Technical field

The invention relates to the field of precision instruments, and in particular to a spatial confinement and physical and chemical analysis system for insoluble gases and a method of using the same.

Background technique

In some research in the fields of biomedicine, chemistry, and genetic engineering, it is necessary to transport specific gases in a liquid fluid environment, or to study the properties or interactions of certain gases in a liquid fluid environment. However, since gas in a liquid fluid usually only moves with the movement of the liquid fluid, and it is difficult to achieve relative movement with respect to the liquid fluid, technicians cannot control the gas to be transported in the liquid fluid according to the required path; this provides certain needs Experimental research on gas isolation reactions, quantitative analysis, etc. has brought difficulties. Therefore, how to achieve controllable and directional transport of gas in a static and stable liquid fluid, as well as spatial confinement and controllable reaction of the gas, has become a technical problem that those skilled in the art need to solve urgently.

Contents of the invention

Based on this, in order to solve the problem that the form of gas reactants is difficult to constrain and the physical and chemical reaction processes between different gases are difficult to accurately control and analyze, the present invention provides a spatial constraint and physical and chemical analysis system for insoluble gases and a method of using it.

Among them, the container is installed on the base.

The transport carrier is detachably installed in the container near the bottom. The transport carrier includes a strip-shaped flat base, and the surface of the base is in a hydrophobic and air-friendly state. The hydrophobic and hydrophilic surface of the matrix also contains at least two intersecting trajectory lines. Each trajectory line is in the shape of a parallel double track, and the area where the trajectory lines are distributed on the surface of the substrate is hydrophilic and air-repellent. The trajectory line includes two mutually parallel boundary lines extending along the target conveying direction. The width of the boundary line is g, and the distance between the two boundary lines is D. The trajectory line also includes a plurality of equally spaced rib lines distributed between the two boundary lines. The rib lines extend obliquely from the boundary lines on both sides to the center. The length of each rib line is L and the width is w. The distance between two adjacent rib lines on each boundary line is s; the inclined lines at the corresponding positions of the two boundary lines are symmetrical to each other and do not intersect each other. The spacing between rib lines at corresponding positions on the two boundary lines is d; the angle α between the rib lines and the connected boundary lines is α.

The defoaming pipeline is connected with the storage tank and forms an annular circulation pipeline. The circulation pump is installed in the circulation pipeline and serves as the power source to drive the circulation movement of the fluid medium. There are multiple groups of vibrating rods, which are installed in each section of the circulation pipeline in order to form a multi-stage defoaming component. A sample outlet for outputting defoamed fluid medium is provided at the position corresponding to the end of the multi-stage defoaming component in the defoaming pipeline, and an outlet valve is provided at the sample outlet. The sample outlet of the defoaming device is connected to the medium syringe, and the fluid medium injected into the container by the medium syringe comes from the output of the defoaming device.

As a further improvement of the present invention, the bubble generator includes a gas bottle, a peristaltic pump and a gas injection probe. Gas cylinders are used to store gaseous reactants. The peristaltic pump is used to quantitatively inject gas reactants in the gas bottle to the target location through the gas injection probe. The gas injection probe includes an adjustable positioning component. The positioning component is used to adjust the target position of the bubble generated by the gas injection probe so that the generated bubble is located in the center of the trajectory line on the transport carrier.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which the invention belongs. The terminology used herein in the description of the invention is for the purpose of describing specific embodiments only and is not intended to limit the invention. As used herein, the term "or/and" includes any and all combinations of one or more of the associated listed items.

Example 1

This embodiment provides a bubble directional transport carrier, which is used to directional transport bubbles generated by a target gas in a static and stable liquid fluid environment. As shown in Figures 1 and 2, the transport carrier includes a strip-shaped flat base, and the surface of the base is in a hydrophobic and hydrophilic state (corresponding to the gray shaded area in Figure 2). The hydrophobic and aerophilic surface of the matrix also contains trajectory lines in the shape of parallel double tracks. The area with trajectory lines distributed on the surface of the matrix is hydrophilic and aerophobic (corresponding to the white filled area in Figure 2).

It can be seen from Figure 2 that the trajectory line in the bubble directional conveying vehicle of this embodiment includes two mutually parallel boundary lines extending along the target conveying direction. The distance between the two boundary lines is D, and the width of each boundary line is g. The trajectory line also includes a plurality of equally spaced rib lines distributed between the two boundary lines. The rib lines extend obliquely from the boundary lines on both sides to the center. The length of each rib line is L and the width is w. The distance between two adjacent rib lines on each boundary line is s. The inclined lines at the corresponding positions of the two boundary lines are symmetrical to each other and do not intersect with each other; the distance between the rib lines at the corresponding positions of the two boundary lines is d. The angle α between the rib line and the connected boundary line.

After using the bubble directional transport vehicle as mentioned above, when a certain polar substance or non-polar liquid is selected as the transport medium, and the directional transport vehicle is immersed in a liquid fluid environment composed of the transport medium, the target to be transported will After the gas forms a bubble with a diameter larger than s and d but smaller than D in the center of the two boundary lines of the transport carrier, the bubble can move in an directional direction along the inclined direction of the rib line in the center of the trajectory line.

In the product provided by this embodiment, in order to achieve directional transportation, the distance d between the rib lines at the corresponding positions on the two boundary lines satisfies: 3.5mm≥d≥1.5mm; the angle α between the rib line and the connected boundary line is Meet: 60°≥α≥10°. Among them, L, α, d and D also satisfy: D=2L·sinα+d. And the optimal value of d is 1/3 of D.

In the bubble directional transport vehicle of this embodiment, the trajectory line on the surface of the base body is equivalent to the rail of the rail vehicle, which plays a role in guiding and controlling the movement direction of the bubbles.

The main reason why the bubble directional transport vehicle provided in this embodiment can achieve unpowered transmission of bubbles is that it takes advantage of the differences in the interface states between three different phases of solid, liquid, and gas substances. The specific principle is as follows: the surface of the substrate in this embodiment has a special microstructure with alternately distributed hydrophobic and hydrophilic properties, and this microstructure extends in a track shape. Therefore, on the one hand, when the bubble directional transport carrier is immersed in a liquid fluid environment, the interface state of the fluid medium at the hydrophobic and hydrophilic parts of the substrate surface is inconsistent. On the other hand, when bubbles are formed by injecting them onto the surface of the bubble directional transport carrier in this embodiment, the bubbles will come into contact with the fluid medium and the surface of the substrate. Due to the contact between the "orbital area" and "non-orbital area" parts of the surface of the base body and the gas There is also a significant difference in angle, so the interface states of the "orbital region" and "non-orbital region" of the bubble and matrix surface are also inconsistent. Under the combined action of these two aspects, the surface tension of the liquid transport medium will spontaneously drive the bubbles to move forward along the extension direction of the track until they reach the end of the track line. Therefore, by designing the direction and length of the trajectory line on the surface of the base body in the bubble directional transport carrier, the purpose of directional adjustment of the movement trajectory of the bubbles in the liquid transport medium can be achieved, that is, directional gas transport can be achieved.

When the bubble directional transport vehicle of this embodiment is used to directional transport a specific target gas in a static and stable liquid fluid environment, the directional transport method of the target gas is as follows:

(i) Select a certain polar or non-polar liquid fluid as the transport medium according to the properties of the target gas, and the transport medium constitutes the required liquid fluid environment.

(ii) According to the transportation trajectory of the target gas to be transported, select a bubble directional transportation vehicle with a trajectory line of corresponding length and direction; then immerse the bubble directional transportation vehicle in the liquid fluid environment.

(ⅲ) Inject the target gas to be transported into a static and stable liquid fluid environment and locate it at the center of the boundary line on the surface of the bubble directional transport carrier. When the bubbles formed by the target gas reach a size that meets the transportation conditions, the bubbles of the target gas will The bubble transport carrier is oriented and transported along the extending direction of the trajectory line.

Among them, it is considered that the bubbles must continuously undergo a "contact-disengagement" cycle with the hydrophilic and hydrophobic parts of the carrier to generate an asymmetric force in the horizontal direction, so that long-distance transportation can be achieved. Therefore, the diameter D _bubble of the bubble that satisfies the transportation conditions in this embodiment should also meet the following conditions: D _bubble <D; D _bubble >d; D _bubble > s.

In this embodiment, the difference in the interface state between different areas of the substrate surface and the gas and liquid is the premise and basis for realizing the directional transport of gas in this embodiment. Therefore, in different regions, the difference in contact angle of gas-liquid two-phase materials should be as large as possible. In an ideal state, the contact angle of the hydrophobic and aerophilic part to the liquid phase should be 180°, while the contact angle of the hydrophilic contact part to the liquid phase should be 0°. Since this ideal state is difficult to achieve, starting from the technical goal of realizing gas transportation, the droplet contact angle of the hydrophobic part of the substrate surface in this embodiment is WCA1: WCA1 ≤ 150°; the bubble contact angle is BCA1: BCA1 ≥ 2 °; the droplet contact angle of the hydrophilic part of the substrate surface trajectory area is WCA2: WCA2≥0°; the bubble contact angle is BCA2: BCA2≤120°. As long as the above contact angle range is met, bubble transport can usually be achieved.

In addition, the trajectory line part mainly produces a hydrophilic interface effect. Therefore, in the actual application process, the width of the boundary line and rib line in the trajectory line should not be too wide, otherwise it may cause excessive adsorption of the transport medium and affect the formation of bubbles. "Travel". However, the width of the boundary lines and rib lines in the trajectory lines should not be too narrow, otherwise it may not be possible to generate the interfacial tension that drives the bubbles to continuously move forward. In the actual application process, the width setting of the boundary line and rib line in the trajectory line should be adaptively adjusted according to the specific transmission medium and target gas type, and the best expert experience value should be determined through a large number of experiments.

In this example, the gas directional transport system includes a total of three substances in different physical states, namely the target gas (transport object, gaseous state), the transport medium (providing a static and stable fluid environment, liquid platform) and the bubble directional transport medium ( The interior contains layers of materials with different properties, such as hydrophobic and hydrophilic parts, solid). Therefore, in this embodiment, in order to ensure that stable gas transportation can be achieved, the objects in the three parts of the transportation system should maintain a stable state during mutual dispersion or contact. That is to say, the properties of the three should at least meet the following conditions:

1) There should be no chemical reaction between the three. For example, the transmission medium should be neutral substances such as water and ethanol, and the materials should not be strongly reducing or oxidizing. For example, when choosing an aluminum metal plate to prepare a bubble directional transport vehicle, acidic aqueous solution should never be selected as the transport medium.

2) The solubility of the target gas in the liquid should be as small as possible. For example, when directional transport of HCl gas is required, water should never be chosen as the transport medium.

3) The solid material form should be dense and stable, without adsorption cavities inside, and cannot absorb liquid or gaseous materials in the transportation system. For example, the matrix material in the bubble directional transport vehicle should be dense metal such as aluminum plate, but not porous zeolite and other materials.

4) The transport matrix should be made of materials with low viscosity and good fluidity. For example, water, methanol, ethanol, etc.

Specifically, in this example, the base material is selected from any one of metals, alloys, glass-based and organic resin materials or a composite material of any multiple materials.

In this embodiment, the surface of the substrate is distributed with regions with two different properties: hydrophobic and aerophilic and hydrophilic and aerophobic. Among them, the hydrophobic and aerophilic portion of the surface of the substrate is obtained by using a superhydrophobic modifier to generate a corresponding coating. The superhydrophobic modifier coating can be constructed using any of polytetrafluoroethylene, polycarbonate, polyolefin, polycarbonate, polyamide, polyacrylonitrile, acrylate, and Glaco modifiers. It can also be obtained by performing special surface processing on a specific base material to form a specific microstructure.

Specifically, in this embodiment, Glaco modifier is used to obtain the required hydrophobic and aerophilic surface on the surface of the aluminum substrate. And the required hydrophilic and aerophobic surface structure is constructed by processing a rough surface on the trajectory line portion of the substrate surface.

The bubble directional transport carrier provided in this embodiment has a micro-nano structure with special polarity distribution on its surface. Specifically, it has two different types of surfaces, hydrophilic and hydrophobic. Simply having such surface features can produce the bubble transport capabilities required for this implementation. Among them, the shape of the substrate surface is not limited. It can be a flush smooth structure or a non-smooth uneven structure. For example, in the actual production process, hydrophilic trajectory lines can be produced through a specific process and are slightly higher. On the hydrophobic surface, it appears "scar-like". It can also be slightly below the hydrophobic surface, in a "groove-like" shape. It should be noted that the depressions and protrusions here are relatively microscopic differences, and the scale difference in height difference between the hydrophobic surface and the hydrophilic surface is very small. In fact, the special microstructure of this "scar" or "groove" can, to a certain extent, promote differences in the interface effects of different physical states.

The hydrophobic structure and hydrophilic structure on the surface of the bubble directional transport carrier provided in this embodiment can be constructed from different materials. Therefore, by combining different material properties, products that meet the conditions can be produced through subtractive processing or additive manufacturing. For example, the required bubble directional transport carrier can be prepared through any process such as template method, etching method, chemical vapor deposition method, coating transfer method, etc.

Specifically, in this embodiment, the required sample of the bubble directional transport carrier is processed by etching. The generation process of this embodiment adopts femtosecond laser processing technology. As shown in Figure 3, the preparation process provided by this embodiment mainly includes four process steps, namely: material selection, first laser scanning, coating preparation and Second laser scan.

In particular, in the process flow of generating a bubble directional transport carrier through a femtosecond laser processing system provided in this embodiment, the detailed steps of each process are as follows:

(1) According to the transportation trajectory of the target bubble to be transported, select a strip-shaped aluminum substrate of corresponding size and shape as the base material, so that the transportation trajectory can be completely drawn on the aluminum substrate. In addition, the surface of the aluminum substrate can also be pre-treated to be mirror-like by grinding.

In this embodiment, the aluminum substrate is the base material that produces the hydrophobic layer and the hydrophilic layer surface. By mirroring the base material, the surface structures of different properties processed later can be made more uniform and consistent. This is beneficial to improve the performance of processed hydrophobic and hydrophilic coatings.

(2) Fix the aluminum substrate on the processing machine table of the femtosecond laser processing system, then set the processing parameters of the femtosecond laser processing system, and conduct the first laser scan of the distribution area of the transportation track on the surface of the aluminum substrate using femtosecond laser , processing the mirror surface of the aluminum substrate into a hydrophilic rough surface.

In this embodiment, the surface of the aluminum substrate is roughened by irradiating the aluminum substrate with laser, and the roughened surface of the aluminum substrate becomes a hydrophilic surface. There are two main reasons for roughening the surface of the aluminum substrate in this embodiment: 1. In the later stage of this embodiment, it is planned to attach a special super-hydrophobic coating to the aluminum substrate to obtain the required hydrophobic surface. Therefore, after roughening the surface of the aluminum substrate, the adhesion strength between the superhydrophobic modified coating material and the aluminum alloy substrate can be improved, making the constructed hydrophobic structural layer more stable. 2. In this implementation plan, a hydrophilic area (i.e., the trajectory line part) needs to be processed inside the hydrophobic layer. After the hydrophobic coating has been constructed into a hydrophilic structure, it is only necessary to remove the surface layer of the specific area in the subsequent processing. The hydrophobic modified layer can "expose" the hydrophilic layer below. The preparation method of this embodiment just adopts this process design idea.

In this embodiment, the femtosecond laser processing system consists of the Chameleon Vision-S seed laser and the Legend Elite F HE-1K titanium sapphire chirped pulse amplification system from the American Coherent Company. Among them, the laser wavelength, pulse width and frequency of the femtosecond laser processing system are set to 800nm, 104fs and 1kHz respectively. During the processing, the laser power and scanning speed were set to 40mW and 40mm/s respectively. During this laser scanning process, the processing area is a long rectangular area.

(3) Spray Glaco modifier evenly on the hydrophilic surface of the aluminum substrate after roughening in the previous step, and then form a hydrophobic surface composed of Glaco modified layer after the Glaco modifier is cured. The Glaco agent used in this embodiment is a super-hydrophobic modifier product with excellent performance. It can hydrophobicize the surface of the aluminum substrate through simple spraying. After using the Glaco modifier, you only need to let it sit naturally for 2-3 minutes. After the modified layer material solidifies, the required hydrophobic and air-philic layer can be constructed on the surface of the aluminum substrate.

(4) Finally, according to the designed transportation trajectory of the target bubble, set the scanning path of the femtosecond laser processing system, conduct a second scan of the aluminum alloy plate in the previous step, and remove the Glaco modification in the scanning trajectory during the second scanning process. layer, and then process the trajectory line in line with the transportation trajectory on the hydrophobic surface of the aluminum substrate. After the second scan, the trajectory line part of the surface of the aluminum substrate returns to the hydrophilic state; at this time, the bubble directional transportation carrier as mentioned above is obtained.

The reason why the preparation method of this embodiment adopts femtosecond laser processing is mainly to take advantage of the "non-thermal meltability" of the femtosecond laser processing process. Therefore, the diffusion of heat energy to the processing area is greatly reduced, the formation of heat-affected zones is significantly reduced, and there is no selectivity for the type of base material. When femtosecond laser processing is used in this embodiment, the existence of thermal diffusion can be avoided during the duration of the interaction between each laser pulse and the material, fundamentally eliminating the melting zone and heat generation similar to those in long pulse processing. The impact and thermal damage caused by various effects such as impact zones and shock waves on surrounding materials greatly reduces the spatial range involved in the processing process, thus improving the accuracy of laser processing and facilitating the diversification of processing structures.

Of course, femtosecond laser processing is still an etching processing method that uses local high-energy light to remove materials. In order to avoid that during the second femtosecond laser processing, the vaporized or sputtered materials (such as the modified layer and the aluminum substrate) may be re-solidified and fall back outside the trajectory line area of the aluminum substrate, processing in the previous step The performance of the hydrophobic structure coming out is affected. In this embodiment, a vacuum adsorption device can also be installed in the flying laser processing platform to adsorb the airflow or flying dust generated during the processing of this step; keeping the surface of the aluminum substrate clean.

Performance Testing

In order to verify the performance of the product generated by the preparation method provided in this embodiment, this embodiment also formulates corresponding test experiments to test the bubble directional transport carrier generated using an aluminum substrate and Glaco modifier.

1. Surface performance test

During the test process, this implementation first verified the droplet contact angle and bubble contact angle on the surface of the roughened aluminum alloy substrate after the first laser etching. Under microscopic observation conditions, the status of the two is shown in Figures 4 and 5. After measurement, it was found that at this time, the droplet contact angle WCA1=0° and the bubble contact angle BCA1=116° on the surface of the aluminum substrate showed a hydrophilic and aerophobic state.

Then the droplet contact angle and bubble contact angle on the surface of the Glaco-modified aluminum substrate were verified. Under microscopic observation conditions, the status of the two is shown in Figures 6 and 7. After measurement, it was found that at this time, the droplet contact angle WCA2 = 142° of the modified layer on the surface of the aluminum substrate, and the bubble contact angle BCA1 = 2°, indicating a hydrophobic and aerophilic state. It can be seen that the performance of the product processed in this embodiment has reached expectations.

2. Structural layout of trajectory lines

The foregoing content has limited the structure of the trajectory lines in the bubble directional transport carrier designed in this implementation. The basic unit of the trajectory line must include boundary lines and rib lines, but in actual application, based on this repeated unit, trajectory lines with different layouts can be designed to adapt to the transportation paths of bubbles in different scenarios.

Specifically, during this performance testing phase, four typical trajectory line forms (as shown in the upper part) as shown in Figure 8-11 were actually generated, and the bubble transport effects under four different conditions (as shown in the lower part) were studied ).

In Figure 8, the trajectory lines are arranged in a rice shape, which is a typical multi-directional straight track. When the generated bubble is located in the center of the rice-shaped structure, if the bubble is subject to an initial drive in any direction, the bubble will continue to move along the track in that direction until it reaches the end of the trajectory line.

In Figure 9, the trajectory line is in an S-shaped layout, which is a typical curved track. When the generated bubble is located at the end of the track, the bubble can move slowly along the track line to the other end of the rib line's inclination direction and reach the other side of the track line. Through observation, we also found that during the movement of the bubbles in this example, the movement speed is slower and more unstable than the state in Figure 8. This may be caused by the uneven distribution of the rib lines on both sides of the boundary line.

In Figure 10, the trajectory lines are distributed in a U-shape, which is a typical composite track, including three separate sections of straight track, and curved tracks at both ends connected in the middle. Under this kind of turntable, the bubble transport characteristics are the same as those in the previous two embodiments. In particular, during the test, it was observed that the movement state of the bubbles also changed when they reached the curved track that connected with the straight track. This also confirmed to a certain extent the analysis of the reasons for the changes in the movement state of the bubbles caused by the curved track in this embodiment. .

In Figure 11, the trajectory line is Y-shaped, which is a bifurcated track, and the track at the bifurcation is narrower than the width of the original track. In this kind of track, larger bubbles can be transported on the wider track, but they cannot reach the narrow track after the bifurcation. Smaller bubbles can transition from wide to narrow orbits. The reason for this phenomenon is that in this embodiment, the size of the bubbles that can be transported by the bubble directional transport carrier is related to the specification of the trajectory line, and the diameter of the bubble D _bubble needs to be within the following range: D _bubble <D; D _bubble >d;D _bubble > s. Therefore, when a large bubble reaches a narrow track from a wide track, because the bubble diameter is already greater than the boundary line width D, the transportation conditions are not met. At this time, the bubble automatically rises and breaks. Since the diameter of the small bubble is smaller than the width of the wide track and the narrow track, it can be transported on both sections at the same time.

3. Research on conveying performance

In the trajectory of the bubble directional transport carrier designed in this embodiment, the inclination direction α of the rib line in the center of the boundary line determines the final transport direction of the bubbles. That is to say: the angle between the rib line and the boundary line has an impact on the transportation ability of the bubbles. Specifically, when the angle α is smaller, (it tends to coincide with the rib line and the boundary line), the directional transportation effect of the bubbles will gradually become worse. However, when the angle becomes larger (it tends to become perpendicular to the shape line and the boundary line), the revelation track loses its "polarity" and cannot guide the bubble to move in a certain direction. The bubble can undergo random two-way transport, which is not consistent with The design goals of this utility model.

Based on the research, it was found that the transportation performance of the bubble directional transportation vehicle has the greatest correlation with the structural parameters d and α. In order to clarify the influence of the two, a large number of control experiments were also combined in the test test to draw the diagram shown in Figure 12. Distribution diagram of bubble transport effect under different d and α conditions.

In Figure 12, the bubble transportation effect is divided into three areas, namely: In area (I), the bubbles appear in a pinning state, that is, they cannot be transported normally. In area (II), the bubbles exhibit one-way transport, that is, directional transport can be achieved. In area (III), bubbles exhibit two-way transport, that is, they can be transported but cannot be controlled. It can be seen from this that only the range of region (II) belongs to the effective structural parameters in the design process of the bubble directional transport vehicle in this embodiment. Specifically, the distance d between the rib lines at the corresponding positions on the two boundary lines satisfies: 3.5mm ≥ d ≥ 1.5 mm; the angle α between the rib lines and the connected boundary line satisfies: 60° ≥ α ≥ 10°.

Technicians can also combine the distribution diagram in Figure 12 and solve the optional ranges of d and α through linear programming. Specifically, the linear programming process is: first fit the first curve d1=f1(α) according to the boundaries of area (I) and area (II); and then fit the first curve d1=f1(α) according to the boundaries of area (II) and area (III) Draw the second curve, d2=f2(α); then use d1, d2, and 60°≥α≥10° as constraint conditions to obtain the required ranges of d and α.

Example 2

On the basis of the delivery vehicle 3 designed in Embodiment 1, this embodiment further provides a spatial confinement and physical and chemical analysis system for insoluble gases. This system is used to provide a controllable reaction environment for different gas reactants, spatially constrain the gas within the reaction environment, and study the physical and chemical properties of the gas reactants themselves, or the physical and chemical reactions between different gas reactants.

As shown in Figure 13, the spatial confinement and physical and chemical analysis system for insoluble gases provided by this embodiment includes a base 1, a container 2, a transport carrier 3, a medium injector 4, a defoaming device 5, and multiple groups of bubble generators 6.

Among them, the container 2 is made of transparent glass or resin material; the transparent container 2 can make it easier to observe the physical and chemical reaction process between the reactants inside. The container 2 is installed on the base 1.

The transport carrier 3 is detachably installed in the container 2 near the bottom. The transport carrier 3 adopts the product as in the previous embodiment. The transport carrier 3 includes a strip-shaped flat base body, and the surface of the base body is in a hydrophobic and aerophilic state. As shown in Figure 14, the hydrophobic and aerophilic surface of the substrate in this embodiment also contains at least two intersecting trajectory lines. Each trajectory line is in the shape of a parallel double track, and the area where the trajectory lines are distributed on the surface of the substrate is hydrophilic and air-repellent. The trajectory line includes two mutually parallel boundary lines extending along the target conveying direction. The width of the boundary line is g, and the distance between the two boundary lines is D. The trajectory line also includes a plurality of equally spaced rib lines distributed between the two boundary lines. The rib lines extend obliquely from the boundary lines on both sides to the center. The length of each rib line is L and the width is w. The distance between two adjacent rib lines on each boundary line is s; the inclined lines at the corresponding positions of the two boundary lines are symmetrical to each other and do not intersect each other. The spacing between rib lines at corresponding positions on the two boundary lines is d; the angle α between the rib lines and the connected boundary lines is α.

The medium injector 4 is used to inject fluid medium as a transport medium and a reaction medium into the container 2 . The fluid medium completely immerses the transport carrier 3 in the container 2 .

The defoaming device 5 is installed outside the base 1 and is used for defoaming the fluid medium injected into the container 2 .

The bubble generator 6 is used to quantitatively extrude each gas reactant to be reacted onto the trajectory line on the surface of the transport carrier 3 immersed in the fluid medium, and form a gradually expanding diameter in the center of the two boundary lines in the trajectory line of bubbles.

In the spatial constraint and physical and chemical analysis system provided by the present invention, after the diameter of the bubbles formed by each gas reactant on the surface of the transport carrier 3 meets the condition that it is greater than s and d of the respective trajectory line and less than D, the diameter of each gas reactant is The bubbles intersect toward the center along their respective trajectories, and after the intersection, they merge and undergo physical and chemical reactions.

In the space constraint and physical and chemical analysis system provided in the embodiment, the fluid medium and all gas reactants constitute a reaction system. When studying the physical and chemical reactions between different gas reactants, different fluid media are selected to form the reaction system. The fluid media in each reaction system must meet the following properties:

(1) The fluid medium does not chemically react with any gas reactant.

(2) The solubility of each gas reactant in the fluid medium is less than a preset solubility threshold.

(3) The viscosity of the fluid medium is less than a preset viscosity threshold.

In the actual application process, when the purpose of the reaction system is different, different transport vehicles can be selected3. For example, when you only study the properties of a single gas and do not need to control the motion of the gas, choose a blank substrate without trajectory lines. When it is necessary to move the bubbles in a directional manner, only the transport carrier 3 with a single-channel trajectory line needs to be used. When multiple gases need to be fused and reacted, a transport carrier 3 with a multi-channel trajectory that finally intersects is used.

In particular, the base platform 1 in this embodiment is a vibration isolation platform based on active vibration isolation technology. The vibration isolation platform is a precision optical shock-absorbing platform that can eliminate the impact of external shock or vibration on certain precision instruments or equipment and provide a stable environment for other equipment. The purpose of selecting the vibration isolation platform as the machine platform in this embodiment mainly includes two points: on the one hand, it is to keep the surface of the transport carrier 3 installed in the container 2 in a horizontal state at all times during the reaction and analysis. Facilitates motion control of bubbles in fluid media. On the other hand, the influence of the external environment on the reaction system inside the container 2 is eliminated, so that the fluid medium maintains the required static and stable state at all times, and the control accuracy and smoothness of the bubble motion state are improved. There are many types of vibration isolation platforms. In this embodiment, an active vibration isolation platform with higher performance is selected. The sensor inside the vibration isolation platform detects the vibration source in the environment, and then uses the actuator to generate a force opposite to the environment to offset it. environmental impact.

The defoaming device 5 in this embodiment adopts an ultrasonic defoaming device 5 . As shown in FIG. 15 , the defoaming device 5 includes a storage tank 51 , an inlet valve 52 , an outlet valve 53 , a circulation pump 54 , a defoaming pipeline 55 , and a vibrating rod 56 . The storage tank 51 is used to store the fluid medium to be defoamed. The storage tank 51 has an openable and closable liquid injection port. The inner cavity of the storage tank 51 is also connected to the container 2 through an inlet valve 52 . The defoaming pipeline 55 is connected with the storage tank 51 and forms an annular circulation pipeline. The circulation pump 54 is installed in the circulation pipeline and serves as a power source to drive the fluid medium to circulate. The number of vibrating rods 56 is multiple groups, which are installed in each section of the circulation pipeline in order to form a multi-stage defoaming assembly. A sample outlet for outputting defoamed fluid medium is provided in the defoaming pipeline 55 at a position corresponding to the end of the multi-stage defoaming component, and an outlet valve 53 is provided at the sample outlet. The sample outlet of the defoaming device 5 is connected to the medium syringe 4 , and the fluid medium injected into the container 2 by the medium syringe 4 comes from the output of the defoaming device 5 .

The working process of the defoaming device 5 is as follows: the user injects the selected fluid medium into the storage tank 51 through the liquid injection port, and the fluid medium in the storage tank 51 is driven by the circulation pump 54 to circulate in the defoaming pipeline 55. When the fluid medium passes through the part of the defoaming pipeline 55 where the vibrating rod 56 is installed, the vibrating rod 56 vibrates at high frequency and generates ultrasonic waves. The "cavitation" effect of the ultrasonic waves in the liquid causes the bubbles in the liquid to be discharged. The vibrating rod 56 in the defoaming pipeline 55 is also provided with a corresponding exhaust valve for discharging bubbles in the fluid medium. The fluid medium with bubbles removed flows through the medium syringe 4 through the sample outlet and enters the container 2 . In addition, during the reaction process, when the fluid medium in the container 2 generates a large number of bubbles that are difficult to eliminate due to the reaction, the inlet valve 52 can also be opened to suck the fluid medium in the container 2 into the storage tank 51 for defoaming again. deal with.

The principle of ultrasonic "cavitation" defoaming in this embodiment is as follows: the vibrating rod 56 generates ultrasonic waves and propagates into the fluid medium, thereby generating alternating positive and negative pressure phases in the fluid medium. In the negative pressure (thinning) stage, sufficiently high-intensity ultrasonic waves can overcome the adhesion between molecules and generate a large number of near-vacuum microbubbles in the liquid. As bubbles beat in the ultrasonic field, they accelerate each other and merge, forming larger bubbles. This process proceeds quickly until the bubbles reach sufficient buoyancy to float on the liquid and release previously trapped gas into the environment.

In this embodiment, the bubble generator 6 includes a gas bottle, a peristaltic pump and a gas injection probe. Gas cylinders are used to store gaseous reactants. The peristaltic pump is used to quantitatively inject gas reactants in the gas bottle to the target location through the gas injection probe. The gas injection probe includes an adjustable positioning component. The positioning component is used to adjust the target position of the bubble generated by the gas injection probe so that the generated bubble is located in the center of the trajectory line on the transport carrier.

The hydrophobic surface of the substrate is obtained by using a superhydrophobic modifier to generate a corresponding coating. Superhydrophobic modifier coatings are constructed using any one of polytetrafluoroethylene, polycarbonate, polyolefin, polycarbonate, polyamide, polyacrylonitrile, acrylate, and Glaco modifiers. The matrix is prepared by selecting any one of metal, alloy, glass-based and organic resin materials or a composite material of any multiple materials.
