Description

Technical Field

[0001] The present application relates to the technical field of packing, and particularly to a high-throughput structured packing. Background Art

[0002] Packed towers play a huge role in modern industrial production and are widely used in many fields such as chemical engineering, biology, medicine, environmental protection, etc. The packings in the tower are divided into random packings and structured packings. Random packings are mostly used in experimental-scale towers, and high-efficiency structured packings are more commonly used in industrial production packed towers.

[0003] For example, a high-throughput structured packing disclosed in Chinese Patent Publication No. (CN220677867U) includes a number of forward corrugated sheets and a number of reverse corrugated sheets, and the forward corrugated sheets and the reverse corrugated sheets are parallel to each other and arranged alternately. The forward corrugated sheets and the reverse corrugated sheets are fixed by tying straps. The end faces of the forward corrugated sheets and the reverse corrugated sheets are not flush. For the high-throughput structured packing described in this utility model, the forward corrugated sheets and the reverse corrugated sheets are staggered in the vertical direction, increasing the voids at the top and bottom of the structured packing, realizing the buffering of the rising gas in the packed tower, effectively preventing the occurrence of flooding phenomenon, increasing the material flux, and the processing capacity of the packed tower can be increased by 15 - 20% under the same conditions after adopting this utility model.

[0004] However, the prior art exemplified by the above-mentioned disclosed patent still has the problem of poor lamination adjustment effect for structured packings. In the prior art, the forward corrugated sheets and the reverse corrugated sheets are fixed by tying straps, and the shape of the corrugated sheets is used to realize the structured packing. However, the flux of this method is fixed and it is not convenient to adjust according to specific process requirements and fluid characteristics to make the packing reach the best performance. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the present application provides a high-throughput structured packing, which has the advantages of convenient lamination adjustment, etc., and solves the problem of poor lamination adjustment effect for structured packings.

[0006] To achieve the above object, the present application provides the following technical solution: A high-throughput structured packing includes a fixed outer ring and a spliced outer ring. An adjustment mechanism is provided on the inner walls of the fixed outer ring and the spliced outer ring, and a packing mechanism is provided on the inner wall of the adjustment mechanism;

[0007] The adjusting mechanism includes two threaded inner liners and two adjusting rings. The two threaded inner liners are respectively fixed to the inner walls of the fixed outer ring and the splicing outer ring. The two adjusting rings are respectively threadedly connected to the inner walls of the two threaded inner liners. Adjusting screw holes are formed in the lower surfaces of the two adjusting rings. An adjusting bolt is threadedly connected to the inner wall of the adjusting screw hole. An ejecting column is slidably connected to the inner wall of the adjusting screw hole above the adjusting bolt. A connecting groove is formed in the right inner wall of the adjusting screw hole, and a return spring is fixed to the inner wall of the connecting groove, and the other end of the return spring is fixed with a clamping block.

[0008] By adopting this technical solution, the distance between the fixed outer ring and the splicing outer ring can be adjusted as needed, increasing the flexibility and adaptability of the packing to adapt to different process conditions.

[0009] Furthermore, a slot is formed in the lower surface of the fixed outer ring, and an inserting ring corresponding to the position of the slot is fixed to the upper surface of the splicing outer ring.

[0010] By adopting this technical solution, a simple connection method is provided, facilitating the assembly and fixation of multiple splicing outer rings and improving the installation efficiency.

[0011] Furthermore, fixing screw holes are formed in the opposite sides of the inserting ring and the slot, and fixing bolts are threadedly connected to the inner walls of the fixing screw holes.

[0012] By adopting this technical solution, the use of the fixing screw holes and the fixing bolts ensures the connection stability between the splicing outer ring and the fixed outer ring, enhancing the firmness of the overall structure.

[0013] Furthermore, a splicing groove with the same depth as the inner cavity of the slot is formed in the lower surface of the splicing outer ring, and a hand wheel is fixed to the bottom end of the adjusting bolt.

[0014] By adopting this technical solution, the use of the fixing screw holes and the fixing bolts ensures the connection stability between the splicing outer ring and the fixed outer ring, enhancing the firmness of the overall structure.

[0015] Furthermore, a sliding opening is formed in the left inner wall of the adjusting screw hole, and the clamping block is slidably connected between the front and rear inner walls of the sliding opening.

[0016] By adopting this technical solution, the design of the sliding opening allows the clamping block to move flexibly during the adjustment process, improving the flexibility and adjustment accuracy of the adjusting mechanism.

[0017] Furthermore, guiding inclined surfaces are formed in the opposite sides of the clamping block and the ejecting column.

[0018] By adopting this technical solution, the design of the guiding inclined surfaces helps the clamping block to cooperate smoothly with the ejecting column during the adjustment process, reducing friction and wear during adjustment.

[0019] Furthermore, the packing mechanism includes a first honeycomb packing plate and a second honeycomb packing plate. The first honeycomb packing plate and the second honeycomb packing plate are respectively fixed to the inner walls of two adjusting rings, and hydrophobic films are coated on the outer sides of both the first honeycomb packing plate and the second honeycomb packing plate.

[0020] By adopting this technical solution, the arrangement of the first honeycomb packing plate and the second honeycomb packing plate provides a layered mass transfer surface, while the application of the hydrophobic film enhances the anti-pollution ability and liquid redistribution ability of the packing.

[0021] Furthermore, a number of honeycomb holes are formed inside both the first honeycomb packing plate and the second honeycomb packing plate, and the inner diameter of the honeycomb holes in the second honeycomb packing plate is smaller than that in the first honeycomb packing plate.

[0022] By adopting this technical solution, the design of honeycomb holes with different inner diameters allows the packing mechanism to be optimized according to the flow rate and mass transfer characteristics of the fluid. The smaller honeycomb holes in the second honeycomb packing plate contribute to improving the mass transfer efficiency, especially when dealing with high-viscosity or high-load fluids.

[0023] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0024] 1. For this large-throughput structured packing, the adjusting mechanism provides an accurate and repeatable spacing adjustment mechanism through the cooperation of the threaded inner liner and the adjusting ring. It can dynamically adjust the distance between the honeycomb packing plates according to specific process requirements and fluid characteristics, optimize the flow and distribution of the fluid in the packing layer, thereby improving the mass transfer efficiency and processing capacity. In addition, the locking mechanism composed of the adjusting bolt, the ejecting column, the clamping block and the return spring ensures the stability of the adjusted spacing, prevents the adjustment from failing due to vibration during the operation process, and enhances the reliability and safety of the operation of the packed tower.

[0025] 2. For this large-throughput structured packing, the honeycomb packing plate design adopted by the packing mechanism provides a larger specific surface area, which is beneficial to increasing the contact opportunities between the fluid and the packing and improving the mass transfer efficiency. Especially, the honeycomb pore sizes of the first honeycomb packing plate and the second honeycomb packing plate are different, and can be optimized according to the requirements of fluid dispersion and mixing. The hydrophobic film coated on the outer side of the honeycomb packing plate further reduces the retention of liquid on the packing surface and improves the gas passing rate, which is particularly important for improving the performance of the packed tower under high humidity or liquid phase load conditions. This design enables the packed tower to maintain good operating performance and high processing capacity when dealing with fluids with different viscosities, densities and surface tensions.

Specific embodiments

[0031] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0032] Please refer to Figure 1 , a large-throughput structured packing in this embodiment includes a fixed outer ring 1 and a spliced outer ring 2. An adjustment mechanism 3 is provided on the inner walls of the fixed outer ring 1 and the spliced outer ring 2, and a packing mechanism 4 is provided on the inner wall of the adjustment mechanism 3.

[0033] Please refer to Figures 2 to 3, To facilitate the adjustment of the structured packing, the adjustment mechanism 3 in this embodiment includes two threaded inner liners 31 and two adjustment rings 32. The two threaded inner liners 31 are respectively fixed to the inner walls of the fixed outer ring 1 and the spliced outer ring 2. The two adjustment rings 32 are respectively threadedly connected to the inner walls of the two threaded inner liners 31. Adjustment screw holes 33 are formed on the lower surfaces of the two adjustment rings 32. An adjustment bolt 34 is threadedly connected to the inner wall of the adjustment screw hole 33. An ejection post 35 is slidably connected to the inner wall of the adjustment screw hole 33 above the adjustment bolt 34. Loosen the adjustment bolt 34 so that the adjustment ring 32 can rotate along the inner wall of the threaded inner liner 31. Using the adjustment bolt 34 as a lever, rotate the adjustment ring 32 and move it within the threaded inner liner 31 to achieve precise adjustment of the packing layer spacing. A connection groove is formed on the right inner wall of the adjustment screw hole 33, and a return spring 36 is fixed to the inner wall of the connection groove. The other end of the return spring 36 is fixed with a block 37. After the adjustment is completed, tighten the adjustment bolt 34. As the bolt is tightened, it will push the ejection post 35 upward. Under the action of the guiding inclined surface, the block 37 is pushed outward. The block 37 slides out along the sliding opening and abuts against the threaded inner liner 31 to play a limiting role and prevent the adjustment ring 32 from accidentally rotating.

[0034] In this embodiment, a slot 38 is formed on the lower surface of the fixed outer ring 1, and a plug ring 39 corresponding to the position of the slot 38 is fixed to the upper surface of the spliced outer ring 2. According to the use requirements, the spliced outer ring 2 is inserted into the slot 38 of the fixed outer ring 1 through the plug ring 39 to form structured packing of different heights. Fixed screw holes are formed on the opposite sides of the plug ring 39 and the slot 38, and a fixing bolt is threadedly connected to the inner wall of the fixed screw hole. The plug ring 39 is fixed to the outer rings 1 and 2 using the fixing bolt to ensure the stability of the connection. A splicing groove with the same depth as the inner cavity of the slot 38 is formed on the lower surface of the spliced outer ring 2. When multiple outer rings are spliced and used, they can be connected into the required stacked structure through the cooperation of the plug ring 39 and the splicing groove. Adjust the spacing between the packing layers according to the requirements. A handwheel is fixed to the bottom end of the adjustment bolt 34. A sliding opening is formed on the left inner wall of the adjustment screw hole 33, and the block 37 is slidably connected between the front and rear inner walls of the sliding opening. Guiding inclined surfaces are formed on the opposite sides of the block 37 and the ejection post 35.

[0035] It should be noted that when the spacing needs to be readjusted, loosen the adjustment bolt 34 downward, and the ejection post 35 will fall accordingly. The elastic force of the return spring 36 pulls the block 37 back to its original position. After the block 37 is reset, the adjustment ring 32 can be rotated again to adjust the spacing to adapt to different process conditions. After the spacing adjustment and fixation are completed, install the packing mechanism 4 on the adjustment ring 32 to ensure that the first honeycomb packing plate 41 and the second honeycomb packing plate 42 are correctly placed and fixed. Start running the fluid in the packed tower and use the surface area provided by the structured packing for mass transfer operations.

[0036] Please refer to Figure 4 , in order to improve the flux of structured packing, the packing mechanism 4 in this embodiment includes a first honeycomb packing plate 41 and a second honeycomb packing plate 42. The first honeycomb packing plate 41 and the second honeycomb packing plate 42 provide a large surface area through their honeycomb structures, which increases the chance of fluid contact with the packing, thereby improving the mass transfer efficiency, contributing to the uniform distribution of the fluid in the packing layer, ensuring the full flow of the fluid in the entire packing layer. The first honeycomb packing plate 41 and the second honeycomb packing plate 42 are respectively fixed to the inner walls of the two adjusting rings 32, and hydrophobic films 43 are coated on the outer sides of the first honeycomb packing plate 41 and the second honeycomb packing plate 42. By means of the adjusting bolts 34 and the adjusting rings 32 in the adjusting mechanism 3, the spacing between the honeycomb packing plates can be adjusted to adapt to different fluid characteristics and operating conditions. The hydrophobic films 43 coated on the outer sides of the honeycomb packing plates help to reduce the retention of liquid on the packing surface and improve the gas passing rate.

[0037] In this embodiment, a number of honeycomb holes are formed inside both the first honeycomb packing plate 41 and the second honeycomb packing plate 42, and the inner diameter of the honeycomb holes of the second honeycomb packing plate 42 is smaller than that of the first honeycomb packing plate 41. The first honeycomb packing plate 41 and the second honeycomb packing plate 42 have honeycomb holes with different inner diameters. This design can be optimized according to the requirements of fluid dispersion and mixing, and improve the flow efficiency of the fluid in the packing layer.

[0038] The working principle of the above embodiment is as follows:

[0039] (1)According to the usage requirements, insert the splicing outer ring 2 into the slot 38 of the fixed outer ring 1 through the insertion ring 39 to form regular packings with different heights. Use the fixing bolts to fix between the insertion ring 39 and the outer rings 1 and 2 to ensure the stability of the connection. When multiple outer rings are spliced and used, they can be connected into the required stacked structure through the cooperation of the insertion ring 39 and the splicing groove. Adjust the spacing between the packing layers according to the requirements. First, loosen the adjusting bolt 34 so that the adjusting ring 32 can rotate along the inner wall of the threaded inner cylinder 31. Use the adjusting bolt 34 as a force-applying rod to rotate the adjusting ring 32 and move within the threaded inner cylinder 31 to achieve precise adjustment of the spacing between the packing layers. After the adjustment is completed, tighten the adjusting bolt 34. As the bolt is tightened, it will push the ejecting column 35 upward. Under the action of the guiding inclined surface, the ejecting column 35 will push the block 37 outward. The block 37 slides out along the sliding opening and abuts against the threaded inner cylinder 31 to play a limiting role and prevent the adjusting ring 32 from accidentally rotating. When the spacing needs to be readjusted, loosen the adjusting bolt 34 downward, and the ejecting column 35 will fall accordingly. The elastic force of the return spring 36 pulls the block 37 back to its original position. After the block 37 is reset, the adjusting ring 32 can be rotated again to adjust the spacing to adapt to different process conditions. After the spacing adjustment and fixation are completed, install the packing mechanism 4 on the adjusting ring 32 to ensure that the first honeycomb packing plate 41 and the second honeycomb packing plate 42 are correctly placed and fixed. Start running the fluid in the packed tower and use the surface area provided by the regular packing for mass transfer operations.

[0040] (2)The first honeycomb packing plate 41 and the second honeycomb packing plate 42 provide a large amount of surface area through their honeycomb structures, which increases the opportunity for the fluid to contact the packing, thereby improving the mass transfer efficiency and contributing to the uniform distribution of the fluid in the packing layer to ensure that the fluid flows fully throughout the packing layer. By adjusting the adjusting bolt 34 and the adjusting ring 32 in the adjusting mechanism 3, the spacing between the honeycomb packing plates can be adjusted to adapt to different fluid characteristics and operating conditions. The hydrophobic film 43 coated on the outside of the honeycomb packing plate helps to reduce the retention of liquid on the packing surface and improve the gas passing rate. The first honeycomb packing plate 41 and the second honeycomb packing plate 42 have honeycomb holes with different inner diameters, and this design can be optimized according to the requirements of fluid dispersion and mixing to improve the flow efficiency of the fluid in the packing layer.
