Packing for a mass transfer column and method for producing a packing

The present invention relates to a packing for a mass transfer column.

Furthermore, the present invention relates to a method for producing a packing for a mass transfer column.

By means of mass transfer columns, such as rectification or air separation columns, it is possible to decompose liquefied air into their constituents. Such

Mass transfer column has a cylindrical container in which so-called packages are arranged. Here, a distinction is made between disordered and ordered packs. Disordered packages are beds of defined shaped bodies such as rings, cylinders, calipers or the like. in the

In contrast, in ordered packages metal fabric or sheets are folded and / or wound so that it comes to an intensive steering of the steam and the liquid and the associated intensive contact both. In ordered packs, several packs of discs are stacked on top of each other. The

Packing discs are each in turn made of a variety

built up stacked packing sheets. Packing sheets can be corrugated from a continuous sheet metal strip of a certain width by means of a forming machine and then cut into specific lengths. Packing disks made of such packing sheets can be arranged one on top of the other. Most of the packing discs are aligned so that the packing sheets are crossed. Considering a single packing sheet on the underlying packing disk, this packing sheet should contact a plurality of the underlying packing sheets of the underlying packing disk. Due to manufacturing tolerances, however, it happens that the packing sheet only two underlying

Packing sheets touched, that is, due to the high rigidity of the

Packungsbleche only a two-point contact arises. This has the consequence that it comes to disruptions of the running liquid in the pack and to a so-called Maldistribution (unequal distribution). This can reduce the efficiency of the entire mass transfer column. WO 03/008092 A1 shows a pack with a plurality of packing sheets arranged parallel to one another. The package has an upper edge region and an intermediate main region which has an oblique corrugation, wherein the corrugations of adjacent packaging plates intersect. A part of the packing sheets in the upper edge region has alternately first and second zones in the direction of the upper packing sheet edge. In the first zones, the corrugations from the main area continue unchanged in the edge area. The hydraulic resistance of the packing in the second zones is lower than in the main area.

Against this background, an object of the present invention is to provide an improved packing for a mass transfer column. Accordingly, a packing for a mass transfer column is proposed. The package comprises a first package disk comprising a plurality of first package sheets, and a second package disk comprising a plurality of second package sheets. The first packing disc and the second

Packing disc are arranged on top of each other. A respective end face of the first packing sheets comprises a multiplicity of first deformation elements. The first deformation elements point before a stacking of the first

Packing disk and the second packing disk a non-deformed state and after the stacking of the first packing disk and the second packing disk a deformed state for forming a plurality of contact points between the first packing sheets and the second

Packing sheets on. The first packing sheets each include one

Sheet metal section, wherein the first deformation elements are materialeinstückig formed on the respective sheet metal portion, and wherein the first deformation elements protrude from the sheet metal portion.

By the first deformation elements yielding (or deforming) due to a weight force of the first packing disk or the second packing disk, it can be ensured that a first packing sheet touches a multiplicity of second packing sheets of the second packing on its end face. In other words, the resistance on the face of the first Packing sheets lowered by providing the first deformation elements. Thus, a single two-point contact can be prevented. Consequently, you can

Fluid drainage disturbances at the transitions between two packing slices are reduced. Furthermore, the efficiency of the package is increased. In addition, the allowable manufacturing tolerances of the packing sheets can be increased and thereby costs can be saved.

The deformation elements are of the non-deformed state in the

deformed state can be brought. For this purpose, the deformation elements are adapted to deform in the stacking of the first packing disk and the second packing disk such that the first

Deformation the plurality of contact points between the first

Packing plates and the second packing sheets form. In which

Arranging the first packing disk and the second packing disk causes the compression of the first packing disk and the second packing disk

Deformation elements. The deformation elements are set up to elastically and / or plastically deform when the first pack and the second pack are arranged one on top of the other. The deforming is, for example, upsetting. Preferably, the deformation elements are elastically and / or plastically upset by 10 to 70%, 20 to 60% or 30 to 50% of their length or spring elastically by 0.5 to 20%, 2 to 15% or 5 to 10% of their length , In order to effect the deformation of the deformation elements, an additional force can be temporarily applied to the weight of the overlying packing disks. It is understood that only the first deformation elements are spent in the deformed state, the corresponding points of contact to the second

Form packing plates, that is, the remaining first deformation elements remain in the undeformed state.

According to one embodiment, in the stacking up of the first

Packing disc and the second packing disc the variety of the first

Packing sheets crossed arranged to the plurality of second packing sheets. The respective end face of the first packing sheets touches each of the second packing sheets directly underneath or above with the aid of the first

Deformation elements. The first deformation elements, which contact the second packing sheets, are made so soft that the first deformation elements, which contact the second packing sheets, are deformable due to the weight force pressing from above. This can ensure that a maximum number of transitions between the first packing disk and the second packing disk are formed.

The first packing sheets each comprise a sheet metal section. The first deformation elements are material integral formed on the respective sheet metal section.

The first deformation elements protrude from the sheet metal section. This has the advantage that no joining methods have to be used. Furthermore, no additional or different materials need to be used.

According to a further embodiment, in the deformed state, a respective first deformation element is bent about an attachment cross section thereof with the sheet metal section. In the present case, an "attachment cross-section" means a notional limit cross-section between the sheet-metal section and a respective deformation element

Deformation element (or a direction in which a respective first

Deformation of the sheet metal section protrudes) 0 °. Accordingly, an angle greater than 0 ° arises when bending the first deformation element about the connection cross-section. For example, the first deformation element in the deformed state has a curvature. Preferably, the first

Deformation even in the undeformed state a curvature.

For example, a curving of a respective first deformation element in the case of being brought into the deformed state thereof can take place by means of elastic and / or plastic deformation. According to another embodiment, the first deformation element is bent in the undeformed state relative to the sheet metal section by a bending angle. In this case, the bending angle is increased in the deformed state. Thus, the first deformation element in the undeformed state is for example pre-bent. By means of bringing the first deformation element into the deformed state, the first deformation element is bent further. In this case, two successive first deformation elements in the undeformed state along the respective end face of the first packing plate in

be bent different directions, that is, the first

Deformation along this end face are bent alternately with a positive and negative angle relative to the sheet metal section.

In a further embodiment, the first deformation element in the undeformed state has a wave crest. Further, in the deformed state, a height of the crest is larger than in the undeformed state.

Thus, during deployment of the first deformation element, the wave crest is compressed from the undeformed state to the deformed state.

For example, the first deformation element in the undeformed state has two, three or a multiplicity of wave crests. Accordingly, wave crests and wave troughs alternate along a wave direction. Such a corrugation direction runs, for example, perpendicular to the wave crests. The corrugation direction can also be seen as the direction of a respective first deformation element. When the first deformation element is moved from the undeformed state to the deformed state, in addition to the swaging of the wave crest (or crests), bending may be made around the bending angle between the sheet section and the respective first deformation element. In a further embodiment, the sheet metal section of the respective first

Packungsblechs wave peaks and troughs, which alternate along a direction perpendicular to the wave crests first direction.

The wave crests and wave troughs of the sheet metal section can be referred to, for example, as a primary wave. Furthermore, the wave crests of the sheet metal section For example, rounded or run to a point. The first direction and the

Well direction of the deformation element clamp an angle. This angle is for example between 10 and 90 °, 20 and 80 °, 30 and 70 ° or 50 and 60 °. In a further embodiment, the first deformation elements are each configured rectangular, triangular, trapezoidal or parallelogram.

These forms of the first deformation elements arise when viewing the first package sheet in a plan view. In this case, the shape of a respective first deformation element is limited by an outer contour of the deformation element and the connection cross-section to the sheet metal section. Such

Shape consideration is preferably in the undeformed state of the first deformation elements. In a further embodiment, the first deformation elements are designed as first spring elements.

Accordingly, when the first deformation element is moved from the undeformed state to the deformed state, compression takes place. The compression takes place substantially elastically, whereby also small plastic parts can be present. With the aid of the design of the spring elements, in particular a respective spring constant, the formation of the plurality of contact points can be controlled accordingly. For example, the first spring elements of the first

Packing disk forming contact points to the second packing disk, connected in parallel.

In a further embodiment, the first spring elements are designed as leaf springs. This has the advantage that a clear mode of action of the spring element is ensured. Furthermore, the leaf springs can be provided with little effort.

In a further embodiment, a respective end face of the second packing sheets comprises a multiplicity of second deformation elements, which are located in front of the first Arranging the first packing disk and the second packing disk in a non-deformed state, and after arranging the first packing disk and the second packing disk, have a deformed state for forming a plurality of contact pads between the first packing sheets and the second packing sheets.

Correspondingly, the second deformation elements are configured to deform in the arrangement of the first packing disk and the second packing disk such that the second deformation elements have a plurality of contact points between the first packing sheets and the second packing disk

Form packing plates. For example, the first deformation elements and the second deformation elements face each other. Preferably, the first deformation elements and the second deformation elements are adapted to, in the stacking of the first packing disk and the second

Packing disc interact and deform. For example, the second deformation elements can be brought from a non-deformed state into a deformed state. The provision of the second deformation elements further increases the likelihood of forming the plurality of contact pads between the first package sheets and the second package sheets.

Preferably, the second deformation elements are designed as second spring elements. An interaction of a first spring element with a second spring element is preferably a series connection of the spring elements.

In a further embodiment, the first deformation elements and the second deformation elements are configured identically.

This has the advantage that the first packing sheets and the second packing sheets can be produced in an identical process, resulting in a

Cost saving leads. The identical embodiment means that

for example, the first deformation elements and the second

Deformation elements are produced in the same process.

Furthermore, a mass transfer column with a packing as described above is proposed. The packing is arranged in a container of the mass transfer column. The

Mass transfer column may comprise a plurality of packages, which may be arranged in the container to each other. In addition, a method for producing a packing, in particular as described above, proposed for a mass transfer column. The

A method comprises the following steps: a) providing a first packing disk having a multiplicity of first packing sheets, which have a multiplicity of first deformation elements on their respective end faces, the first ones being the first packing disk

Packing plates each comprise a sheet metal section, wherein the first

Deformation elements are materialeinstückig formed on the respective sheet metal portion, and wherein the first deformation elements protrude from the sheet metal portion, b) providing a second packing disk having a plurality of second

Packing sheets, and c) arranging the first packing disk and the second packing disk, wherein in the stacking-up the first

Deformation elements from a non-deformed state to a deformed state for forming a plurality of pads between the first

Packing plates and the second packing sheets are spent. According to one embodiment, in providing the first packing disk for forming the first deformation elements, a respective blank sheet is entrained

Incisions or recesses provided. Subsequently, the respective blank sheet for forming wave crests and troughs, which alternate along a plane perpendicular to the wave crests first direction, transformed.

For example, after the forming of the blank sheet, cutting takes place to the first packing sheet. Furthermore, subsequently the first packing sheets can be stacked to the first packing disk. Preferably, the second

Packing disc produced analogously. The provision of incisions or

Recesses before generating the wave crests and wave troughs has the advantage that the cuts and recesses can be provided on a flat plate (and correspondingly on a straight edge). This simplifies the production of the packing sheets. For example, the recesses have a rectangular, triangular, trapezoidal or parallelogram shape. The incisions have an incision angle to an edge of the blank sheet at which the incisions be made on. The incision angle is for example 90 °. Alternatively, the incision angle may also be between 30 and 90 °, 40 and 90 °, 50 and 90 ° or 60 and 90 °. The embodiments and features described for the package apply to the method according to and vice versa. The count words "first, second, etc.", such as for the packing sheets, packing disks or

Deformation elements used, serve only to better distinguishability of the respective elements and are arbitrarily interchangeable.

In the present case, "on" is not necessarily to be understood as restricting to exactly one element, but rather to several elements, for example two, three or more, and any other used counting word is not to be understood as limiting to exactly the same Number of elements must be realized. Rather, numerical deviations up and down are possible.

Further possible implementations of the package and / or the method also include combinations of features and embodiments which have not been explicitly mentioned above and which have been described above or below with regard to the exemplary embodiments. The skilled person will also add individual aspects as improvements or additions to the respective basic form of the pack and / or the method.

Unless otherwise indicated.

Fig. 1 shows a highly simplified schematic sectional view of an embodiment of a mass transfer column 1. The mass transfer column 1 may be a rectification or air separation column. By rectification is meant a thermal separation process which is an extension of the distillation or a series connection of many distillation steps. Compared to distillation, the advantages of rectification are that the plant can be operated continuously and that the separation effect is many times higher than that of distillation, since the vapor is in countercurrent contact with the liquid several times in succession. The Mass transfer column 1 thus operates energetically more favorable, technically less expensive and space-saving than a series connection of

Simply distillations. The mass transfer column 1 comprises a container 2, which is a cylindrical

Has geometry. The container 2 may for example be made of an aluminum material or a steel material. Preferably, the container 2 is made of an aluminum material. The container 2 is cylindrically constructed around a symmetry or center axis M2. The container 2 may for example have a height of 30,000 to 50,000 mm. The container 2 may have a circular or approximately circular, for example an oval, cross-section. The container 2 is preferably constructed of many container sections or jacket sections, which are materially connected to one another. The container sections may also be referred to as container sections, jacket sections or jacket sections. The center axis M2 is vertical in the orientation of FIG. H. in

Gravity direction, arranged.

In the container 2, a plurality of stacked packages 3 is arranged, of which in Fig. 1, however, only one is shown. The package 3 is a so-called ordered or structured package. In such packages 3, in contrast to disorderly packages, metal fabric or metal sheets folded and / or wound so that it comes to an intensive steering of the steam and the liquid and the associated intensive contact both. By further structuring of the surface and by the attachment of holes, both the wettability of the packing surface and the mass transfer column are further increased.

The package 3 can have a plurality of ordered or structured packing disks 4 to 8, which are arranged one above the other. This is a first

Packing disk 4 is arranged under a second packing disk 5, wherein the second packing disk 5 rests on the first packing disk 4. Furthermore, a third packing disk 6 lies on the second packing disk 5, a fourth

Packing disc 7 on the third Packungsscheibe 6 and a fifth

Packing disc 8 on the fourth packing disc 7 on. The packing disks 4 to 8 may also be referred to as packing layers or packing layers. Such packing disks 4 to 8 consist of thin, corrugated and / or perforated metal plates or wire nets. The design of packing discs 4 to 8 ensures an optimum exchange between the different phases (liquid / gaseous or liquid / liquid) with minimal pressure resistance. The number of packing disks 4 to 8 per pack 3 is arbitrary.

The packing disks 4 to 8 are made of vertically arranged first

Packing sheets 10 (Fig. 2), in particular made of corrugated aluminum sheets. The packing disks 4 to 8 form due to their structure

Condensation surfaces, for example, in the air separation

Air components can condense. For example, the first

Packing sheets 10 have a thickness of 0.1 mm. The packing disks 4 to 8 are not segmented. That is, the package disks 4-8 are not divided into individual package packages. Each packing disk 4 to 8 may, for example, have a thickness of 100 to 500 mm. The package 3 may thus have a height H3 of, for example, 1,000 to 7,000 mm. Between the container 2 and the packing 3 or between the container 2 and each packing disk 4 to 8, a circumferential packing collar or sealing collar 9 can be provided. The sealing collar 9 is optional and thus dispensable.

Fig. 2 shows a schematic perspective view of a part of a

Embodiment of the first packing sheet 10, of a plurality of which the first packing disk 4 is constructed. The first packing sheet 10 includes a

Sheet metal section 1 1. The sheet metal section 1 1 of the first packing sheet 10 has

Wave peaks 12 and troughs 13 on, extending along a perpendicular to the

Wave crests 12 extending first direction R1 alternate. In this case, the center axis M2 and the first direction R1 clamp a first angle α. The first angle α is for example between 20 and 70 °, 30 and 60 ° or 40 and 50 °,

in particular 45 °. In this case, the wave peaks 12 and troughs 13 as

Primary wave to be called. In addition, the first packing sheet 10

Have corrugations, perforations, holes and / or breakthroughs. The first packing sheet 10 may also be net or lattice. The first packing sheet 10 is preferably made of an aluminum mini umwerkstoff and may, as already mentioned, have a thickness of 0.1 mm. To make the first

Packing disk 4 is a plurality of such first packing sheets 10th stacked. The second, third, fourth and fifth packing disk 5, 6, 7, 8 are constructed analogously, for example.

Fig. 3 shows a schematic perspective view of the first packing disk 4 and the second packing disk 5 in a stacking the same, wherein the first packing disk 4 and the second packing disk 5 are shown spaced from each other. When installed, the second is located

Packing disc 5 directly on the first packing disc 4. The first

Packing disk 4 comprises a plurality of the first packing sheets 10. A respective first packing sheet 10 has an end face 14. In this case, the front side 14 is an upper end side, so that a sum of the end faces 14 forms an upper side 15 of the first packing disk 4. The top 15 is the first

Packing disk 4 a bottom 16 of the second packing disk 5 faces. The bottom 16 of the second packing disk 5 is made of a variety

End faces 17 of second packing sheets 18 of the second packing disk 5 are formed. The end face 17 forms a lower end face of the second

Packing plate 18 off. Thus, when the first packing disk 4 and the second packing disk 5 are stacked on each other, the upper side 15 and the lower side 16 come into contact. In the stacking of the first packing disk 4 and the second packing disk 5, the plurality of first packing sheets 10 are arranged crossed to the plurality of second packing sheets 18. Ideally, the respective end face 14 of the first packing sheets 10 touches each of the directly overlying second packing sheets 18 in order to ensure a high efficiency of the packing. As can be seen from FIG. 3, the second packing disk 5 is rotated by, for example, 90 ° about the center axis M2 relative to the first packing disk 4.

FIG. 4 shows a schematic perspective view of the first packing disk 4 with a single second packing sheet 18, which is arranged on the first packing disk 4. The other second packing sheets 18 are not shown to illustrate the positional relationship. It can be seen that the end face 17 of the second packing plate 18 on a plurality of end faces 14 of the first

Packing plates 10 rests. Thus, the second packing plate 18 is crossed over to the first packing sheets 10. 5 shows a first packing sheet 10 in a schematic perspective view. The end face 14 of the first packing sheet 10 includes a plurality of first deformation members 19 which form a non-deformed state before stacking the first packing disk 4 and the second packing disk 5 and a deformed state after forming the first packing disk 4 and the second packing disk 5 Have a plurality of contact points 23 (Fig. 9) between the first packing sheet 10 and the second packing sheets 18. Thus, the end face 14 touches a plurality of end faces 17 of the second packing sheets 18 by means of the first deformation elements 19. Such touching means that a contact point 23 (FIG. 9) is formed between the first packing sheet 10 and the second packing sheet 18.

The first deformation elements 19 are materialeinstückig formed on the respective sheet metal portion 1 1. In the undeformed state, the first deformation elements 19 protrude from the sheet metal section 11 in a second direction R2 (also referred to as the direction of projection). The second direction R2 and the first direction R1 include a second angle β. Preferably, the second angle β is 90 °. For example, the second angle β can also be between 20 and 90 °.

Fig. 6 shows a schematic perspective view of a section Vl-Vl of Fig. 5. It can be seen that the first deformation elements 19 in the

undeformed state each having a wave crest 20. This can

For example, be referred to as corrugation of the respective first deformation element 19. The primary shaft and the corrugation of the first deformation element 19 (wave crest 20) represent different corrugations.

FIG. 7 shows a schematic side view of the first deformation element 19 with a wave crest 20, as shown in FIG. 6. The first deformation element 19 has a connection cross section 21 to the sheet metal section 11. In this case, the connection cross section 21 can only be regarded as a fictitious limit cross section, since the first deformation element 19 is connected to the sheet metal section 11 in the form of a single piece of material. In the undeformed state, the first deformation element 19 has the wave crest 20, wherein in the deformed state a height H of the Wellenbergs 20 is greater than in the undeformed state. The height H extends in a third direction R3, which is perpendicular to the second direction R2. Consequently, when the first deformation member 19 is moved from the

Undeformed state in the deformed state, a compression of the first deformation element 19, and the wave crest 20 causes.

Alternatively, the first deformation element 19 may be present in the undeformed state as a cuboid, which protrudes from the sheet metal portion 1 1, wherein the wave peak 20 is formed only when moving in the deformed state. For example, the first deformation element 19 in the non-deformed state when viewed from the side may have a rectangular geometry. In this case, the first deformation element 19 does not necessarily have to be present as a cuboid, but can also be formed from the third direction R3 (plan view) triangular, parallelogram or trapezoidal.

FIG. 8 shows a further embodiment of the deformation element 19 in a schematic side view. In this case, in the deformed state (shown in phantom), the first deformation element 19 is bent around the connection cross section 21 of the first deformation element 19 with the sheet metal section 11. Bending can also be referred to as bending over. For example, the bending of the first deformation element 19 takes place about a fourth direction R4 which is perpendicular to the second direction R2 and to the third direction R3. In the undeformed state, the first deformation element 19 can not be bent relative to the sheet-metal section 11, so that the sheet-metal section 11 and the deformation element 19 are flat when viewed from a side view. When spending the first

Deformation element 19 in the deformed state becomes the first

Deformation element 19 bent by a bending angle γ relative to the sheet metal portion 1 1. Alternatively, the first deformation element 19 may already have a bending angle γ relative to the sheet metal section 11 in the undeformed state. In this case, the bending angle γ is increased in the deformation in the deformed state. The first deformation element 19 can also be curved during such a movement. Furthermore, a curvature may also be present even before the dispensing, wherein the curvature is increased when being brought into the deformed state, so that a radius of curvature (not shown) is reduced. Moreover, it is also possible that the first deformation element 19 with a wave crest 20th (As shown in Fig. 7) is bent by a bending angle γ about the connection cross-section 21.

The first deformation elements 19 can also be designed as spring elements. For example, the movement of the first deformation element 19 into the deformed state takes place predominantly elastically. Alternatively or additionally, a plastic deformation can take place during the movement. The spring elements may be formed, for example, as leaf springs. Viewed from the direction R3 (top view), the first deformation elements 19 each have a rectangular, triangular, trapezoidal or

parallelogram-shaped shape. In the process, this figure is replaced by the

Connection cross-section 21 limited. 9 shows an interaction of the first deformation element 19 with a second deformation element 22 in a schematic side view. Out

Illustrative reasons are in the illustration shown in FIG

Deformation directions of the first deformation element 19 and the second

Deformation element 22 is rotated in a common plane. However, since the first packing sheets 10 and the second packing sheets 18 can be arranged crossed, the deformation elements 19, 22 are preferably twisted relative to one another, so that the corresponding wave peaks 20 are oriented in different directions. The end face 17 of the second packing sheet 18 comprises a plurality of second deformation elements 22 which form a non-deformed prior to the stacking of the first packing disk 4 and the second packing disk 5

Condition and after the stacking of the first packing disk 4 and the second packing disk 5 have a deformed state for forming a plurality of contact points 23 between the first packing sheets 10 and the second packing sheets 18. FIG. 9 shows the first deformation element 19 and the second deformation element 22 in the deformed state, that is to say after the first packing disk 4 and the second one are arranged one on top of the other

Packungsscheibe 5. Here, the first deformation element 19 and the second deformation element 22 cooperate in such a way that both compared to

deformed undeformed state. The first deformation element 19 and the second deformation element 22 are configured identically. The two deformation elements 19, 22 are designed like the first deformation element 19 shown in FIG. In this case, the second deformation elements 22 are formed on the end face 17 of the second packing disk 5 (as shown in FIG. 3). Alternatively, the deformation elements 19, 22 could be configured as shown in FIG. 8. Furthermore, it is also possible that the first deformation element 19 as shown in Fig. 7 and the second deformation element 22 as shown in Fig. 8 is configured. This would cooperate with two differently configured deformation elements 19, 22. It is understood that due to the crossed arrangement of the first packing sheets 10 and the second packing sheets 18, only the deformation elements 19, 22 cooperate, which are arranged directly above one another.
