Description

Technical Field

[0001] This utility model relates to the field of mass transfer separation, and in particular to an accessory for packing material inside a container and a mass transfer separation device having the packing accessory. Background Technology

[0002] Ceramic structured packing is a high-efficiency packing material used in chemical mass transfer equipment (such as towers). Made of ceramic materials, it features a regular geometric structure and orderly arrangement. Silicon carbide, as a material for ceramic structured packing, has excellent strength and corrosion resistance, but lacks elongation. Therefore, when used as structured packing, it is easily broken by gas-liquid impacts and vibrations during operation. Current technologies typically add a filter downstream of the equipment for periodic maintenance of broken pieces. Furthermore, existing ceramic structured packing exhibits wall flow, which affects mass transfer efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a packing accessory that slows down packing breakage and reduces wall flow, and also to provide a mass transfer separation device with the accessory.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] An accessory for container packing, the accessory comprising:

[0006] Gaskets with through holes are used for placement below the packing; and

[0007] A flow guide is arranged circumferentially around the gasket, extending upward to surround the packing circumference, and the upper end of the flow guide is in close contact with the inner wall of the container to guide the wall flow of the inner wall of the container to the packing.

[0008] In this design, a gasket is positioned below the packing material to buffer it and reduce the likelihood of breakage. The gasket has through-holes, allowing the material to be separated to pass smoothly through and contact the packing. A flow guide is arranged circumferentially around the gasket and extends upwards, enabling it to surround the packing. When the fitting is placed inside a container, the upper end of the flow guide adheres tightly to the inner wall of the container, directing wall flow from the inner wall to the packing, thus preventing wall flow.

[0009] Preferably, the flow guiding portion includes a flow guiding plate, the flow guiding plate including a connecting section and a bent section connected to each other; one end of the connecting section is connected to the circumferential edge of the gasket, the other end of the extended connecting section is connected to the bent section, the bent section extends radially outward toward the gasket to form an angle with the plane where the gasket is located, the connecting section extends perpendicular to the gasket and forms a weir for the wall flow liquid flowing down.

[0010] In this design, when the gasket is installed below the packing, the guide vane is positioned in the gap between the packing and the container of the mass transfer separation equipment, thus preventing wall flow. Furthermore, the guide vane is connected at one end and extends freely at the other, giving it a degree of flexibility to adapt to the gap between the packing and the container of the mass transfer separation equipment. Additionally, the connecting section extends perpendicular to the gasket, not only surrounding the circumferential sidewalls of the packing bottom and thus providing some restraint, but more importantly, it acts as a weir, guiding the liquid phase into the packing for gas-liquid contact. Without the connecting section, the liquid phase might simply flow away from the tower wall.

[0011] Preferably, there are multiple guide vanes, which are arranged circumferentially around the gasket at intervals. There are multiple connecting segments corresponding to the guide vanes, and each connecting segment is arranged tightly around the gasket to form a complete cofferdam.

[0012] In this design, multiple guide vanes are used, with gaps between them. This enhances the deformation capacity of individual guide vanes and allows for variations in the overall diameter of the multiple vanes, thus better adapting to the gap between the packing and the equipment housing. Furthermore, the connecting sections are tightly arranged around the circumference of the gasket, forming a weir that guides the liquid phase into the packing for gas-liquid contact.

[0013] Preferably, the thickness of the guide plate is in the range of 0.5 mm to 2 mm;

[0014] And / or, the length of the connecting segment in the extending direction ranges from 10mm to 50mm;

[0015] And / or, the length of the bent section in the axial direction of the gasket ranges from 10mm to 50mm;

[0016] And / or, the angle between the extension direction of the bent section and the plane where the gasket is located is in the range of 120° to 150°.

[0017] Preferably, the total area of ​​the through holes accounts for more than 80% of the area of ​​the gasket.

[0018] In this scheme, the above configuration is adopted so that the gasket can buffer the packing while reducing the resistance to the flow of the material to be separated.

[0019] Preferably, the thickness of the gasket is in the range of 0.5mm to 5mm, and / or the through hole is a plurality of through holes, each through hole having a diameter in the range of 5mm to 10mm.

[0020] Preferably, the gasket has a shape that includes either a circle or a rectangle;

[0021] And / or, the shape of the through hole includes any one of circular, rectangular and rhomboid shapes.

[0022] Preferably, the material of the accessory is fluoroplastic.

[0023] In this solution, fluoroplastics have lower hardness and higher elongation than ceramic structured fillers such as silicon carbide, which is beneficial for improving the buffering and protection of the filler.

[0024] Preferably, the material of the accessory is PTFE or PFA.

[0025] Preferably, the packing material is a ceramic structured packing material.

[0026] A mass transfer separation device includes an accessory for a container packing as described above, the mass transfer separation device having a plurality of packings, each of which is provided with the accessory below it, the packings being situated on a gasket, and the flow guide surrounding the packings.

[0027] Preferably, the mass transfer separation device further includes a container, the packing is disposed inside the container, and the extended end of the flow guide contacts the inner wall of the container.

[0028] The positive and progressive effects of this utility model are as follows: the gasket is placed below the packing material, which can buffer the packing material and reduce the possibility of packing material breakage; the gasket has through holes, allowing the material to be separated to pass through the gasket smoothly and come into contact with the packing material. The guide part is arranged around the circumference of the gasket and extends in a direction away from the gasket and at an angle to the plane of the gasket, which allows the guide part to surround the periphery of the packing material. When the accessory is placed in a container, the upper end of the guide part is close to the inner side wall of the container, guiding the wall flow of the inner side wall of the container to the packing material, thereby preventing the generation of wall flow.

[0038] Accessory 1, gasket 100, through hole 110, flow guide 200, flow guide plate 210, connecting section 211, bending section 212, extension end 213, included angle α, ceramic structured filler 2. Detailed Implementation

[0039] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0040] Example 1

[0041] This embodiment provides an accessory 1 for filling material inside a container, such as... Figures 1-4 As shown, accessory 1 includes a gasket 100 with a through hole 110 for placement below the packing; and a flow guide 200 arranged circumferentially around the gasket 100, extending upward to surround the packing 2, with the upper end of the flow guide 200 adhering to the inner wall of the container to guide wall flow from the inner wall of the container to the packing. The gasket 100, positioned below the packing, buffers the packing and reduces the possibility of packing breakage. The gasket 100 has a through hole 110, allowing the material to be separated to pass smoothly through the gasket 100 and contact the packing. The flow guide 200, arranged circumferentially around the gasket 100 and extending upward, allows it to surround the packing. When accessory 1 is placed inside the container, the upper end of the flow guide 200 adheres to the inner wall of the container, guiding wall flow from the inner wall of the container to the packing 2, thereby preventing wall flow.

[0042] like Figure 1 and Figure 8 As shown, accessory 1 is used for, as Figure 8 Taking the ceramic structured packing 2 shown as an example, the bottom of the ceramic structured packing 2 is basically on the same plane, and the gasket 100 has a sheet-like structure. The size of the gasket 100 is basically the same as the size of the ceramic structured packing 2, or slightly larger than the size of the ceramic structured packing 2. This container is a container for a mass transfer separation device.

[0043] The flow guide 200 includes a flow guide vane 210, one end of which is connected to the edge of the gasket 100, and the other end extends radially outward toward the gasket 100; as Figure 8 As shown, the extended end 213 of the flow guide 200 has a larger dimension than the gasket 100, which is also larger than the radial dimension of the ceramic structured packing 2.

[0044] Furthermore, the guide vane 210 includes a connecting section 211 and a bent section 212 connected to each other; one end of the connecting section 211 is connected to the circumferential edge of the gasket 100, and the other end of the extended connecting section 211 is connected to the bent section 212. The bent section 212 extends radially outward toward the gasket 100 to form an angle α with the plane where the gasket 100 is located. The connecting section 211 extends perpendicularly to the gasket 100 and forms a weir for the wall flow liquid. When the gasket 100 is installed below the packing 2, it can be located at the gap between the packing and the container of the mass transfer separation device, thereby preventing the generation of wall flow. In addition, the guide vane 210 is connected at one end and has a free extension end at the other end, giving the guide vane 210 a certain degree of flexible deformation capability, thereby adapting to the gap between the packing and the container of the mass transfer separation device. Also, the connecting section 211 extends perpendicularly to the gasket 100, such as... Figure 8 As shown, it can not only surround the circumferential sidewall at the bottom of the packing, thus limiting the bottom of the packing, but more importantly, the connecting section 211 has a certain weir effect, that is, it guides the liquid phase into the packing for gas-liquid contact. Without the connecting section, the liquid phase may flow directly away from the tower wall.

[0045] In one feasible implementation, such as Figure 1 , Figure 2 and Figure 3 As shown, there are multiple guide vanes 210, which are spaced apart and arranged circumferentially around the gasket 100. The multiple guide vanes 210 and the gaps between them enhance the deformation capacity of each individual vane 210, allowing for variations in the overall diameter of the multiple vanes and thus better adapting to the gap between the packing and the equipment housing. Multiple connecting sections 211 correspond to the guide vanes 210, and each connecting section 211 is tightly arranged circumferentially around the gasket 100 to form a complete containment dam, thereby guiding the liquid phase into the packing for gas-liquid contact.

[0046] In another feasible embodiment, the guide portion 200 is configured as an integral guide plate, forming a cylindrical structure at its connecting section and a funnel-shaped opening at its bending section.

[0047] In implementation, the dimensions of each part of the guide vane 210 can be selected according to requirements. The thickness of the guide vane 210 ranges from 0.5mm to 2mm; and / or, the length of the connecting section 211 in the extension direction ranges from 10mm to 50mm; and / or, the length of the bending section 212 in the axial direction of the gasket 100 ranges from 10mm to 50mm; and / or, the angle α between the extension direction of the bending section 212 and the plane where the gasket 100 is located ranges from 120° to 150°.

[0048] The total area of ​​the through holes 110 accounts for more than 80% of the area of ​​the gasket 100. This allows the gasket 100 to buffer the packing while reducing resistance to the flow of the internal medium. Figure 1 , Figure 2 and Figure 3 As shown, the gasket has multiple through holes, which are evenly arranged on the gasket.

[0049] During implementation, the dimensions of other parts of accessory 1 can also be selected according to requirements. Among them, the thickness of gasket 100 ranges from 0.5mm to 5mm, and the diameter of each through hole 110 among the multiple through holes ranges from 5mm to 10mm.

[0050] During implementation, the shape of the gasket 100 can be matched according to the formation of the filler, such as... Figures 1-4 As shown, the gasket 100 is circular. In other embodiments, the gasket 100 may also be rectangular or other shapes. Furthermore, the through-hole 110 can also be configured in various shapes, as in this embodiment... Figure 1 , Figure 2 and Figure 3 As shown, the through hole 110 is circular in shape.

[0051] The material of accessory 1 can be selected to have lower hardness and higher elongation than silicon carbide. As a specific material, accessory 1 is made of fluoroplastic. Preferably, accessory 1 is made of PTFE or PFA.

[0052] In specific implementation, such as Figures 1-7 As shown, the flow guide 200 and the gasket 100 are integrally formed into a single structure. In other embodiments, the flow guide 200 and the gasket 100 can also be separately configured, that is, the flow guide 200 and the gasket 100 are not connected and have a gap between them. In this embodiment, the gasket 100 is disposed below the packing, and the flow guide 200 can be located at any suitable position around the circumferential sidewall of the packing.

[0053] In specific implementation, such as Figures 1-7As shown, accessory 1 forms an integral structure. In other embodiments, accessory 1 can also be a split structure. It is understood that the packing itself can be configured as a split structure, with the packing divided into multiple sub-parts in its circumferential direction, and the multiple sub-parts together forming the packing as a whole. For this type of packing, accessory 1 can also be divided circumferentially into sub-accessories 1 that are adapted to the sub-parts of the packing.

[0054] Example 2

[0055] This embodiment provides a component 1 for filling material inside a container. The structure of component 1 in this embodiment is basically the same as that of the component in embodiment 1, except that, for example... Figure 5 and Figure 6 As shown, the through hole 110 is rhomboid in shape.

[0056] Example 3

[0057] This embodiment provides a component 1 for filling material inside a container. The structure of component 1 in this embodiment is basically the same as that of the component in embodiment 1, except that, for example... Figure 7 As shown, the through hole 110 is rectangular in shape.

[0058] Furthermore, the through hole 110 can be configured with the same shape, or multiple shapes can be configured on the gasket 100 simultaneously as needed.

[0059] Example 4

[0060] This embodiment also provides a mass transfer separation device, which includes an accessory 1 for packing material inside a container as described in any of embodiments 1-3 above. The mass transfer separation device has multiple packing materials, and an accessory 1 is disposed below each packing material. The packing material 2 is located on a gasket 100, and a flow guide 200 surrounds the packing material. In practice, the mass transfer separation device generally has multiple stacked ceramic structured packing materials 2, and an accessory 1 can be disposed below each ceramic structured packing material 2.

[0061] The mass transfer separation equipment also includes a container, with packing material disposed inside the container, and the extended end 213 of the flow guide 200 contacting the inner wall of the container. For example, Figure 4 and Figure 8 As shown, the extension end 213 of the guide section 200 is the extension end of the guide plate 210, that is, the opposite end of the guide plate 210 and the gasket connection end. The ceramic structured filler 2 is a silicon carbide filler 2.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
