Description

A water and medicine dispensing device

Technical Field

The invention relates to the technical field of sewage treatment, in particular to a water and medicine distributing device which can be used for preventing fouling and clogging of a Fenton fluidized bed reactor.

Background Art

Fenton fluidized bed reactors are widely used in the field of water treatment. During its operation, ferrous ions need to react with hydrogen peroxide to produce free radicals with high oxidation capacity, which further oxidize and decompose the organic matter in the wastewater. The Fenton fluidized bed uses a water and drug distribution device to fully and evenly mix water and two liquid medicines and attach the generated FeOOH crystals to the surface of the filler, and stir the water in the reactor to fully vulcanize the crystal filler, greatly improving the reaction efficiency. Therefore, the water and drug distribution device is an extremely important component in the Fenton fluidized bed reactor system, which has three functions: uniform water distribution, mixing liquid medicine, and vulcanizing filler.

Traditional water and medicine distribution devices can be divided into water distribution orifice plates, perforated tubes and water distribution heads. Water distribution orifice plates and perforated tubes are rarely used in fluidized bed reactors because they cannot achieve uniform mixing of the medicine solution. Water distribution heads can fully meet the three functional requirements of fluidized bed reactors and are widely used in fluidized bed reactors. However, in actual operation, water distribution heads are prone to crystal fillers flowing back into the water distribution heads, causing the water distribution heads to become dirty and clogged, affecting the water and medicine distribution effect. In addition, the fillers will also enter other cavities of the equipment, affecting and harming the normal operation of the equipment.

The structure and specific implementation process of the water and medicine dispensing device of the present invention will be described below in conjunction with FIGS. 1 to 6 .

In a specific embodiment of the present invention, a water and medicine dispensing device is provided, as shown in FIG. 1 , comprising a water receiving pipe 1, a water dispersing pipe 2 and a water dispersing switch mechanism 3, wherein a plurality of water inlet holes 11 are provided on the water receiving pipe 1; the water dispersing pipe 2 is connected to the water receiving pipe 1, and a water dispersing hole 21 is provided on the water dispersing pipe 2; the water dispersing switch mechanism 3 is adapted to move relative to the water dispersing pipe 2 to switch between a blocking position and an avoidance position, wherein in the blocking position, the water dispersing switch mechanism 3 blocks the water dispersing hole 21 to close the water dispersing hole 21, and in the avoidance position, the water dispersing switch mechanism 3 avoids the water dispersing hole 21 to open the water dispersing hole 21.

The water and medicine dispensing device in this embodiment can be used to prevent fouling and blockage of Fenton fluidized bed reactors. It is understandable that during the operation of the fluidized bed reactor, the mixed liquid medicine enters the water receiving pipe 1 from the water inlet hole 11 of the water receiving pipe 1, then flows into the water dispersing pipe 2, and flows out from the water dispersing hole 21 of the water dispersing pipe 2. In the water and medicine dispensing device of this embodiment, a water dispersing switch mechanism 3 is provided, and the water dispersing switch mechanism 3 is used to control the opening and closing of the water dispersing hole 21. During the normal operation of the fluidized bed reactor, the water dispersing switch mechanism 3 controls the opening of the water dispersing hole 21, and the mixed liquid medicine flows normally. The liquid medicine flowing out of the water dispersing hole 21 reacts and crystallizes in the reactor and adheres to the surface of the filler. When the equipment is shut down, the liquid medicine stops entering the water receiving pipe 1. At this time, the water dispersing switch mechanism 3 controls the water dispersing hole 21 to close, so that the crystal filler outside the water dispersing hole 21 cannot flow back into the water and medicine dispensing device, which fundamentally solves the problem of crystal filler backflow.

In some examples, the water-spreading pipe 2 is externally connected to the water outlet end of the water-receiving pipe 1, and a plurality of water-spreading holes 21 are arranged circumferentially on the pipe wall of the water-spreading pipe 2. Specifically, four water-spreading holes 21 can be arranged circumferentially along the pipe wall of the water-spreading pipe 2, and the four water-spreading holes 21 are arranged cross-symmetrically, and the aperture size of the water-spreading holes 21 is 8.5 mm.

The water spray switch mechanism 3 is a key structure for controlling the opening and closing of the water spray hole 21. The water spray switch mechanism 3 can be arranged inside the water spray pipe 2 or outside the water spray pipe 2. The structure of the water spray switch mechanism 3 is described below in combination with a specific embodiment structure.

On the basis of the above embodiments, in some embodiments of the water and medicine dispensing device of the present invention, the water dispersing switch mechanism 3 includes a water dispersing pipe seal 31 and a plugging member 32, wherein the water dispersing pipe seal 31 is sleeved on the end of the water dispersing pipe 2 away from the water receiving pipe 1, and at least one pressure balance hole 311 is provided on the water dispersing pipe seal 31; the plugging member 32 is located in the water dispersing pipe 2 and can move along the internal channel of the water dispersing pipe 2 to block or avoid the water dispersing hole 21. Specifically, a boss is provided in the water dispersing pipe 2 to form a first limit position 22, and the inner diameter of the connection between the water dispersing pipe seal 31 and the water dispersing pipe 2 is contracted to form a second limit position 23; the plugging member 32 is suitable for switching between the first limit position 22 and the second limit position 23.

When the water spray switch mechanism 3 is in the blocking position, the blocking member 32 is located at the first limit position 22 and blocks the water spray hole 21 ; when the water spray switch mechanism 3 is in the avoidance position, the blocking member 32 is located at the second limit position 23 and avoids the water spray hole 21 .

It can be understood that, in this embodiment, the water dispersion switch mechanism 3 is located inside the water dispersion pipe 2, and the upper end of the water dispersion pipe 2 is sealed by the water dispersion pipe sealing head 31, so that the sealing member 32 moves up and down in the internal space formed by the water dispersion pipe 2 and the water dispersion pipe sealing head 31, but will not fall out.

Referring to the example structures of Figures 1 and 2 , Figures 1 and 2 illustrate that the blocking member 32 is a spherical body, and the diameter of the spherical blocking member 32 is equal to or slightly smaller than the inner diameter of the water diffusion pipe 2. Initially, as shown in Figure 1 , the blocking member 32 is located at the first limit position 22, and the water diffusion hole 21 is blocked by the blocking member 32.

After the fluidized bed reactor equipment is started, the mixed liquid collected by the water collecting pipe 1 enters the water dispersing pipe 2 from the water collecting pipe 1. Since the diameter of the plugging member 32 is equal to or slightly smaller than the inner diameter of the water dispersing pipe 2, the mixed liquid can bypass the plugging member 32 from the edge to form a bypass resistance or directly push the plugging member 32 upward, so that the plugging member 32 reaches the second limit position 23 from the first limit position 22, as shown in Figure 2. After the plugging member 32 reaches the second limit position 23, the water dispersing hole 21 is opened. Due to the pressure balance hole 311, the pressure above the plugging member 32 is equal to the pressure outside the water dispersing device, and there is continuous mixed liquid entering below the plugging member 32, so the pressure is much greater than the pressure above the plugging member 32, so that the plugging member 32 is always stuck in the second limit position 23, and the mixed liquid continuously flows out of the water dispersing hole 21 to participate in the crystallization reaction of the external filler.

When the equipment is shut down, the mixed liquid medicine stops entering the water collecting pipe 1, and no more mixed liquid medicine enters the space below the blocking member 32. At this time, the blocking member 32 falls back to the first limit position 22 due to the balance of upper and lower pressures and its own gravity, that is, returns to the position shown in FIG. 1. The blocking member 32 at the first limit position 22 just blocks the water diffusion hole 21, so that the external crystal filler cannot flow back into the water and medicine distribution device through the water diffusion hole 21.

3 and 4 , the blocking member 32 is a cylindrical structure, which is similar in principle to the spherical blocking member 32 shown in FIGS. 1 and 2 , and will not be described in detail here. The specific process can refer to the implementation process of the above-mentioned spherical blocking member 32 .

It should be understood that, whether it is a spherical plugging member 32 or a cylindrical plugging member 32, both act on the inside of the water dispersion pipe 2. When the equipment is running, the pressure below the plugging member 32 is greater than the pressure above, and the plugging member 32 is lifted to the second limit position 23 to open the water dispersion hole 21. When the equipment stops running, the pressure below the plugging member 32 disappears. Under the action of the pressure above, the plugging member 32 falls back to the first limit position 22 to block the water dispersion hole 21. Among them, the pressure above the plugging member 32 is connected to the outside world through the pressure balance hole 311. When the outside world connected to the pressure balance hole 311 has a certain pressure, the water and medicine distribution device of the present invention can be arranged in any direction. When the outside world connected to the pressure balance hole 311 is atmospheric pressure, the water and medicine distribution device of the present invention needs to be arranged vertically. When the equipment stops, the plugging member 32 can fall back by its own gravity.

In the above two embodiments, at least one pressure balance hole 311 is provided on the water diffuser head 31. In some specific examples, the pressure balance hole 311 is located on the side wall of the water diffuser head 31. There are an even number of pressure balance holes 311, and they are arranged symmetrically in pairs, for example, they can be set to two or four. Referring to the structures in FIG. 1 to FIG. 4, the pressure balance hole 311 obliquely penetrates the side wall of the water diffuser head 31, and the inclination direction is inclined from the inside of the water diffuser head 31 to the outside toward the direction close to the water diffuser 2; the aperture size of the pressure balance hole 311 is 2 mm. Such a setting can prevent the crystal filler from flowing back into the water and medicine dispensing device from the pressure balance hole 311 to a certain extent, and the blocking member 32 is in the first limit position 22, blocking the water diffuser hole 21 to form a check mechanism, and the blocking member 32 also blocks the end of the water receiving pipe 1 in the first limit position 22, forming a second check mechanism, which strengthens the function of preventing backflow.

In addition to being arranged inside the water dispersion pipe 2, the water dispersion switch mechanism 3 can also be arranged outside the water dispersion pipe 2 for blocking and opening the water dispersion hole 21. In other embodiments, as shown in Figures 5 and 6, the water dispersion switch mechanism 3 includes a sliding sleeve 33 slidably arranged outside the water dispersion pipe 2 and a plug 34 installed at the end of the sliding sleeve 33; when the water dispersion switch mechanism 3 is in the blocking position, the sliding sleeve 33 blocks the water dispersion hole 21; when the water dispersion switch mechanism 3 is in the avoiding position, the sliding sleeve 33 avoids the water dispersion hole 21.

Specifically, an annular retaining portion 331 is provided inside one end of the sliding sleeve 33 that is sleeved on the water diffusion pipe 2, and a limiting convex portion 24 is provided on the outer peripheral surface of the water diffusion pipe 2 away from the water receiving pipe 1. The limiting convex portion 24 is used to cooperate with the annular retaining portion 331 to limit the sliding sleeve 33. It should be understood that in the sealing structure composed of the plug 34 and the annular retaining portion 331 in this embodiment, a pressure balancing hole is also provided (its structure is the same as the pressure balancing hole 311 in the water diffusion pipe sealing head 31 of the above-mentioned embodiment, not shown in the figure), which can be provided in the plug 34 or in the annular retaining portion 331. The pressure balancing hole here also plays a role in balancing the pressure.

As shown in FIG. 5 , initially, the sliding sleeve 33 is entirely sleeved on the outside of the water diffusion pipe 2 , and the sliding sleeve 33 blocks the water diffusion hole 21 .

After the fluidized bed reactor equipment is started, the mixed liquid collected by the water collecting pipe 1 enters the water dispersing pipe 2 from the water collecting pipe 1, and the mixed liquid entering the water dispersing pipe 2 continues to move upward and acts on the plug 34. As the mixed liquid continues to enter, the mixed liquid will push the plug 34 and the sliding sleeve 33 to move upward along the outer periphery of the water dispersing pipe 2 until the annular clamping portion 331 of the sliding sleeve 33 reaches the limiting convex portion 24 of the water dispersing pipe 2. At this time, referring to FIG. 6, the annular clamping portion 331 and the limiting convex portion 24 are restrained and limited, and the water dispersing hole 21 is opened. As the mixed liquid continues to enter, the plug 34 and the sliding sleeve 33 are always resisted and pushed, and the state shown in FIG. 6 is maintained, and the mixed liquid continuously flows out of the water dispersing hole 21 to participate in the crystallization reaction of the external filler.

When the equipment is shut down, the mixed liquid stops entering the water receiving pipe 1, and the plug 34 and the sliding sleeve 33 are no longer pushed by the mixed liquid. Under the action of their own gravity (or the external pressure of the plug 34 and the sliding sleeve 33), they start to move downward until they return to the initial state, that is, the state shown in FIG. 5 . At this time, the sliding sleeve 33 forms a blockage for the water diffusion hole 21 again, so that the external crystal filler cannot flow back into the water and medicine distribution device through the water diffusion hole 21.

Based on the structures of the water and medicine dispensing devices in the above-mentioned embodiments, in this embodiment, the water receiving pipe 1 is vertically arranged, and the water receiving pipe 1 is arranged through the upper mounting plate 4 and the lower mounting plate 5 arranged in parallel. The water dispersing pipe 2 is sleeved on the outside of the top of the water receiving pipe 1, and the bottom end of the water dispersing pipe 2 contacts the upper surface of the upper mounting plate 4; the lower part of the water receiving pipe 1 is sleeved with a fastener 6, and the fastener 6 contacts the lower surface of the lower mounting plate 5.

The water-spreading pipe 2 is externally connected to the water-collecting pipe 1, and the outer diameter of the water-spreading pipe 2 is larger than that of the water-collecting pipe 1, so that the connection between the water-spreading pipe 2 and the water-collecting pipe 1 presents a platform, and this platform cooperates with the fastener 6, as well as the upper mounting plate 4 and the lower mounting plate 5, so that the water-distributing and medicine-distributing device can be fixed on the upper mounting plate 4 and the lower mounting plate 5. Among them, in order to ensure the sealing, sealing gaskets are arranged on the assembly surface between the bottom end of the water-spreading pipe 2 and the upper mounting plate 4, and on the assembly surface between the fastener 6 and the lower mounting plate 5, and the gasket material can be selected as a flexible material. In addition, in order to ensure the stability of the installation, in some examples, the fastener 6 can include a fastener A and a fastener B, and the two fasteners are together mounted on the outside of the water-collecting pipe 1 to form an anti-loosening structure.

In this embodiment, the water inlet 11 includes an upper water receiving hole 111, a middle water receiving hole 112 and a lower water receiving hole 113, wherein one upper water receiving hole 111 can be provided, with a hole diameter of 7 mm, an opening angle perpendicular to the axial direction of the water receiving pipe 1, and a position close to the lower surface of the upper mounting plate 4, which can be used to collect the liquid medicine in the middle layer between the upper mounting plate 4 and the lower mounting plate 5, and release the gas in the middle layer to the uppermost cylinder through the water and medicine distribution device as much as possible, and finally release it into the air. Two middle water receiving holes 112 can be provided, with a hole diameter of 7 mm, and the two middle water receiving holes 112 are arranged opposite to each other, with an opening angle perpendicular to the axial direction of the water receiving pipe 1, and a position close to the upper surface of the lower mounting plate 5, which can be used to collect the liquid medicine in the middle layer between the upper mounting plate 4 and the lower mounting plate 5. The lower water receiving hole 113 is the bottom water inlet of the water receiving pipe 1, which can be used to collect the liquid medicine in the lower layer of the lower mounting plate 5.

Combined with the structures in the above-mentioned embodiments or examples, the water distributing and medicine distributing device provided by the present invention, when the equipment stops or the liquid volume fluctuates and there is a risk of backflow, the water distributing switch mechanism 3 will immediately fall back, block the water distributing hole 21, and block the crystal filler on the outside of the overall water distributing and medicine distributing device, which fundamentally solves the problem of crystal filler backflow. In some examples, the water distributing switch mechanism 3 can also form a second check mechanism to enhance the function of preventing backflow. When the water distributing and medicine distributing device of the present invention is in operation, the water distributing switch mechanism 3 is stably supported in the limit position through the principle of pressure balance difference, avoiding the water distributing switch mechanism 3 from being knocked and worn in the water distributing pipe 2, and improving the service life of the water distributing and medicine distributing device. Moreover, through the setting of the mounting plate and the fasteners, the loosening and falling off of the water distributing and medicine distributing device due to vibration can be avoided, and the stability of operation is improved.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
