Description

Technical Field

[0001] The invention relates to the technical field of chemical packing towers, in particular to an internal support structure of a corrosion chemical packing tower. Background Art

[0002] Chemical packed towers are tower-type equipment used for gas-liquid or liquid-liquid mass and heat transfer processes and are widely used in the chemical, petroleum, and environmental protection industries. Corrosive chemical packed towers are designed for use with corrosive media. Due to the highly corrosive nature of the media being processed, the tower, packing, and internal components must be constructed of corrosion-resistant materials or enhanced with anti-corrosion coatings and linings to ensure long-term, stable operation. Their core feature is the large amount of packing within the tower, which increases the gas-liquid contact area through the packing surface, enhancing mass transfer efficiency in processes such as absorption and distillation.

[0003] In existing technology, the internal support structure of a corrosive chemical packing tower is a component used to support the weight of the packing, while allowing gas and liquid to pass smoothly and being corrosion-resistant. These structures are often constructed using hump-shaped support plates, which have an upwardly convex top and a hollow interior. When large amounts of packing are poured in, significant pressure is exerted on the hump-shaped support plates. Without internal support, the sides of the hump-shaped support plates are prone to deformation, such as dents and bends. This can damage the support plate structure, compromise its support performance, and shorten its service life.

[0004] Therefore, we propose a support structure for a corrosion-resistant chemical packing tower in order to solve the problems raised in the above background technology. Summary of the Invention

[0005] The purpose of the present invention is to provide a support structure inside a corrosion chemical packing tower to solve the problem proposed in the above-mentioned background technology that the support structure inside a corrosion chemical packing tower is hollow when in use.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. When the present invention is used, the pull rod is pulled by the C-hook to pull the limiting ratchet out of the I-shaped block and separate it from the annular ratchet. The turntable is rotated to drive the rotating shaft, I-shaped block, annular ratchet and anti-corrosion gear to rotate together, and at the same time drive the upper and lower tooth plates to move in opposite directions. The two reinforcement support plates are pushed to move by the connecting rod, so that the single-fork support plate and the double-fork support plate are respectively against the three corners inside the step component. The reinforcement rod enters the reinforcement groove, and the two reinforcement support plates are against the spire component. Then push the C-hook downward to make the limiting ratchet engage with the annular ratchet again. While vertically supporting the spire component, the two step components are obliquely supported and reinforced, thereby improving the overall structural strength and structural integrity of the step tower assembly, enhancing its pressure resistance and deformation resistance, ensuring that the structure can remain stable when bearing a large amount of filler, and extending its service life.

[0017] 2. When using the present invention, the support assembly is an independent, detachable module. Under different working conditions, factors such as the weight of the packing in the packing tower vary. By detaching the support assembly and selecting the number of support assemblies as needed, damaged parts can be replaced individually, and the support strength can be flexibly adjusted according to the actual working conditions. Move the clamping shaft to the C-shaped hook, and then move the tool rod to the right to move the clamping shaft into the C-shaped hook. Pushing the tool rod upward can simultaneously push up multiple C-shaped hooks and pull multiple limit ratchets out of the annular ratchet. There is no need to pull the C-shaped hooks one by one. When disassembling multiple support assemblies, the time and steps of disassembly are greatly saved, the disassembly efficiency is improved, and it is more convenient.

[0018] 3. When used, the stepped components of the present invention take on a gentle, curved step shape, making the gas-liquid flow more continuous and gentle, reducing flow resistance and energy loss, while increasing the length of the gas-liquid contact path, thereby improving mass transfer efficiency. The central, pointed tip of the tower guides gas and liquid to flow to both sides, and in conjunction with the stepped components on both sides, distributes the fluid more orderly across the entire tower cross-section. The inclined holes are tilted toward the tower's inner wall, which helps guide gas and liquid closer to the tower's inner wall, improving gas-liquid distribution in the edge area and allowing the edge fillers to fully participate in the mass transfer process.

[0019] 4. When the present invention is in use, the bottom guide assembly provides auxiliary support for the stepped tower assembly, increasing the overall load-bearing capacity of the stepped tower assembly. At the same time, the radial guide plates form radial strip supports, which have a good guiding effect, allowing the liquid to flow more orderly within the tower. In particular, they can effectively guide the liquid to the edge areas, increase the liquid flow rate in the edge areas, reduce liquid retention in the edge areas, and promote better gas-liquid contact. The tapered spikes help force the fluid to disperse, forming multiple streams, thereby more fully contacting the reaction. BRIEF DESCRIPTION OF THE DRAWINGS

One end of the rotating shaft 409 is movably embedded in the rear surface wall inside the fixed cover 404. One end of the rotating shaft 409 movably penetrates the front surface of the fixed cover 404. The auxiliary tool assembly 5 includes a tool rod 501. The top surface of the tool rod 501 is provided with multiple threaded grooves 502. The internal threads of the threaded grooves 502 are embedded with L-shaped rods 503. One end of the L-shaped rod 503 is fixedly mounted with a clamping shaft 504.

[0024] In this embodiment, when in use, according to the internal dimensions of the first support frame 1, a step tower assembly 3 of corresponding size is selected and installed in the first support frame 1. Adjacent step tower assemblies 3 are fixedly connected together to form a complete step tower support structure, such as Figure 1As shown. Each stepped tower assembly 3 consists of a tower top component 301 and two stepped components 302. A plurality of reinforcement grooves 305 are provided at the three corners inside the two stepped components 302. Five reinforcement grooves 305 form a group, and multiple groups of reinforcement grooves 305 are provided. The single-fork support plate 402 has one arc-shaped fork, and the double-fork support plate 403 has two arc-shaped forks. There are three arc-shaped forks on one side of a reinforcement support plate 401. Five reinforcement rods 405 are installed on the inner wall of each arc-shaped fork. There are three groups of five in a group. The positions of the three groups of reinforcement rods 405 correspond to the three groups of reinforcement grooves 305 at different positions at the three corners inside the stepped component 302. The initial positions of the two reinforcement support plates 401 are close to both sides of the fixed cover 404. By pulling the pull rod 422 upward through the C-shaped hook 426 (under the action of the third sealing ring 425, the pull rod 422 is tightly embedded in the third sealing hole 424, and external pulling force is required to make the pull rod 422 move up and down in the third sealing hole 424), the limiting ratchet 421 is pulled out from the I-shaped block 416 and separated from the annular ratchet 417. At this time, the I-shaped block 416 loses its fixation and the rotating shaft 409 becomes active. Place the support assembly 4 inside the stepped tower assembly 3, and align the three groups of reinforcement rods 405 on both sides with the reinforcement slots 305 at the corresponding positions. Then rotate the turntable 415 to drive the rotating shaft 409, the I-shaped block 416, the annular ratchet 417 and the anti-corrosion gear 408 to rotate together, while driving the upper and lower toothed plates 410 to move in opposite directions. By pushing the connecting rod 411 to move, the two reinforcement support plates 401 are pushed to the sides, and the single-fork support plate 402 and the double-fork support plate 403 are pushed to the inner corners of the stepped component 302. When the single-fork support plate 402 and the double-fork support plate 403 respectively collide with the three corners inside the stepped component 302, the reinforcement rods 405 simultaneously enter the reinforcement slots 305, and the tops of the two reinforcement support plates 401 respectively collide with the two sides inside the tower top component 301. Figure 5 and Figure 7As shown. The turntable 415 is then stopped, and the C-shaped hook 426 is pushed downward. The pull rod 422 pushes the limiting ratchet 421 back into the I-shaped block 416, reengaging the annular ratchet 417. This secures the rotating shaft 409 and prevents the anti-corrosion gear 408 from rotating on its own, which would affect the tightening and supporting force of the reinforcement support plate 401, the single-prong support plate 402, and the double-prong support plate 403 on the stepped tower assembly 3. The number of support assemblies 4 installed can be selected based on the length of the stepped tower assembly 3, and can be installed in different positions for support. The reinforced support plate 401 in the support assembly 4 supports both sides of the interior of the tower top component 301 to provide vertical support force, and the single-fork support plate 402 and the double-fork support plate 403 are used to obliquely support and reinforce the inner walls of the two step components 302, effectively sharing the weight of the filler and other external forces, and dispersing the pressure to other supporting structures, thereby improving the overall structural strength and structural integrity of the step tower assembly 3, enhancing its pressure resistance and deformation resistance, ensuring that the structure can remain stable when bearing a large amount of filler, and extending its service life. It solves the problem that when the support structure in the corrosive chemical packing tower is in use, its interior is hollow. When a large amount of filler is poured in, there is a lack of internal support, and the side of the hump support plate is easily squeezed by pressure, resulting in deformation such as depression and bending, which damages the support plate structure and affects its support performance.

[0025] Furthermore, support assembly 4 is configured as a independently removable module. Under different operating conditions, factors such as the weight of the packing within the packed tower vary. By making the support assembly 4 removable and available in selectable quantities, the support strength can be flexibly adjusted based on the actual operating conditions. Furthermore, the installation positions of reinforcement groove 305 and support assembly 4 do not affect flow holes 303. This increases the strength and bearing capacity of the internal support structure without affecting the normal operation of the packed tower.

[0026] Furthermore, by repeating the installation process of the above-mentioned support assembly 4, the reinforcement support plate 401, the single-fork support plate 402 and the double-fork support plate 403 can be moved and reset by reversing the turntable 415, and at the same time, the reinforcement rod 405 is moved out of the reinforcement groove 305, and the individual support assembly 4 can be removed. The detachable design facilitates the replacement of damaged parts individually without the need to remove the support plate as a whole, thereby reducing the difficulty and cost of maintenance.

[0027] Furthermore, the L-shaped rod 503 on the tool rod 501 can be selected according to the number of corresponding support components 4, such as Figure 6As shown, when there are six support assemblies 4, six L-shaped rods 503 at corresponding positions are threadedly connected through the thread groove 502. The tool rod 501 is moved to the bottom of the fixed cover 404, and the L-shaped rod 503 and the clamping shaft 504 are moved to the C-shaped hook 426. Then, the tool rod 501 is moved to the right so that the six clamping shafts 504 are all moved into the C-shaped hook 426. Then, the tool rod 501 is pushed upward so that the six L-shaped rods 503 drive the six clamping shafts 504 to move upward at the same time, and the six C-shaped hooks 426 can be pushed upward at the same time, that is, the six limiting ratchets 421 are pulled out of the annular ratchet 417 at the same time. Finally, the staff only needs to rotate the turntable 415 in reverse order to remove multiple support assemblies 4 from the inside of the stepped tower assembly 3, without having to pull the C-shaped hooks 426 one by one. When disassembling multiple support assemblies 4, the disassembly time and steps are greatly saved, the disassembly efficiency is improved, and it is more convenient.

[0028] Example 2: Figure 1 、 Figure 5 and Figure 7 As shown, a bottom guide assembly 2 is provided at the bottom of the first support frame 1, a step tower assembly 3 is provided inside the first support frame 1, and a support assembly 4 is provided inside the step tower assembly 3; the step tower assembly 3 includes a spire component 301, and step components 302 are fixedly installed on both sides of the bottom of the spire component 301, and a plurality of reinforcement grooves 305 are provided at the three corners inside the two step components 302, and a plurality of flow holes 303 are provided on the outer surfaces of both sides of the spire component 301 and the tops of the two step components 302, and a plurality of inclined holes 304 are provided at the two corners of the outer surfaces of the two step components 302, the cross-sections of the two step components 302 are both stepped, and the corners of the outer surfaces of the two step components 302 are both curved, and the outer surface of the step tower assembly 3 is fixedly installed on the inner wall of the first support frame 1.

[0029] In this embodiment, when in use, the stepped tower assembly 3 has a central sharp angle and a curved stepped design on both sides. The stepped structure changes the gas-liquid flow path, causing the fluid to continuously change direction during ascent or descent, increasing the chances of gas-liquid mixing and contact, and more evenly distributing it throughout the packing layer. The stepped component 302 has a soft curved stepped shape, making the gas-liquid flow more continuous and gentle, reducing flow resistance and energy loss, while increasing the length of the gas-liquid contact path, which is beneficial for improving mass transfer efficiency. The central sharp angle of the tower top component 301 can guide the gas and liquid to flow to both sides, and in conjunction with the stepped components 302 on both sides, the fluid is more orderly distributed throughout the tower cross-section, avoiding excessive concentration of fluid in the central area. The inclined hole 304 is tilted and tilted toward the tower inner wall, which helps guide the gas and liquid to the vicinity of the tower inner wall, improves the gas-liquid distribution in the edge area, allows the edge packing to fully participate in the mass transfer process, and improves the mass transfer uniformity of the entire tower. All structural components involved in this internal support structure are made of corrosion-resistant materials.

[0030] Example 3: Figure 2-Figure 4 As shown, a bottom guide assembly 2 is provided at the bottom of the first support frame 1, a stepped tower assembly 3 is provided inside the first support frame 1, a support assembly 4 is provided inside the stepped tower assembly 3, and the bottom guide assembly 2 includes a second support frame 201, a mounting frame 202 is fixedly installed on the top surface inside the second support frame 201, a plurality of radiation guide plates 203 are fixedly installed on the outer surface of the bottom of the mounting frame 202 by bolts, a plurality of conical nails 204 are fixedly installed on the top and bottom of the plurality of radiation guide plates 203, an outer surface of one side of the plurality of radiation guide plates 203 is bolted to the bottom surface of the inner wall of the second support frame 201, the outer surface of the top of the second support frame 201 is movably embedded in the bottom surface inside the first support frame 1, and the first support frame 1 and the second support frame 201 are connected by bolts.

[0031] In this embodiment, when in use, the bottom of the stepped tower assembly 3 is connected to the bottom guide assembly 2 by bolts, and the bottom guide assembly 2 provides auxiliary support to the stepped tower assembly 3, thereby increasing the overall load-bearing weight of the stepped tower assembly 3 and ensuring the overall strength of the structure. A plurality of radial guide plates 203 are installed in the second support frame 201, which are radially distributed, and the flow channel width gradually increases from the center to the edge. The radial strip support has a good guiding effect. It can guide the liquid flowing from the central area to the edge area into the edge flow channel, preventing the liquid from being deflected or gathering in the central area during the flow process. This guiding effect allows the liquid to flow more orderly in the tower, especially effectively guiding the liquid to the edge area, increasing the liquid flow rate in the edge area, reducing liquid retention in the edge area, and promoting better contact between gas and liquid. A plurality of conical nails 204 are installed on the top and bottom of the radial guide plate 203, which is conducive to forcing the fluid to disperse and form multiple streams to flow, thereby more fully contacting the reaction.

[0032] The effect and working principle of the entire mechanism are as follows: by pulling the pull rod 422 upwards through the C-shaped hook 426, the limit ratchet 421 is pulled out of the I-shaped block 416 and separated from the annular ratchet 417. The support assembly 4 is placed inside the step tower assembly 3, and the three sets of reinforcement rods 405 on both sides are aligned with the reinforcement grooves 305 at corresponding positions. Then, the turntable 415 is rotated to drive the rotating shaft 409, the I-shaped block 416, the annular ratchet 417 and the anti-corrosion gear 408 to rotate together, while driving the upper and lower toothed plates 410 to move in opposite directions. By pushing the connecting rod 411 to move, the two reinforcement support plates 401 are pushed to the sides, and the single-pronged support plate 402 and the double-pronged support plate 403 are pushed to move toward the inner corner of the step component 302. When the single-pronged support plate 402 and the double-pronged support plate 403 respectively contact the three corners inside the stepped component 302, the reinforcement rod 405 simultaneously enters the reinforcement groove 305, and the tops of the two reinforcement support plates 401 contact the two sides inside the spire component 301. The C-shaped hook 426 is then pushed downward, causing the limiting ratchet 421 to engage the annular ratchet 417 again. At this point, the reinforcement support plates 401 support the two sides inside the spire component 301, providing vertical support force. The single-pronged support plate 402 and the double-pronged support plate 403 provide oblique support and reinforcement for the inner walls of the two stepped components 302, effectively sharing the weight of the filler and other external forces, and enhancing their resistance to compression and deformation. Move the tool rod 501 to the bottom of the fixed cover 404, and move the L-shaped rod 503 and the clamping shaft 504 to the C-shaped hook 426. Then move the tool rod 501 to the right, so that all six clamping shafts 504 move into the C-shaped hook 426. Then push the tool rod 501 upward, so that the six L-shaped rods 503 drive the six clamping shafts 504 to move upward simultaneously, thereby pushing the six C-shaped hooks 426 upward simultaneously, that is, simultaneously pulling the six limiting ratchets 421 out of the annular ratchet 417. Finally, the staff only needs to rotate the turntable 415 in the opposite direction to remove the multiple support assemblies 4 from the interior of the stepped tower assembly 3. The central pointed tower tip component 301 can guide the flow of gas and liquid to both sides, and cooperate with the stepped components 302 on both sides to distribute the fluid more orderly throughout the entire tower cross-section. The stepped components 302 have a soft curved step shape, which makes the gas and liquid flow more continuous and gentle, reduces flow resistance and energy loss, and increases the length of the gas-liquid contact path, which is conducive to improving mass transfer efficiency. The bottom guide assembly 2 provides auxiliary support for the stepped tower assembly 3, thereby increasing the overall load-bearing capacity of the stepped tower assembly 3. Meanwhile, the radial guide plates 203 form radial strip supports, which have a good guiding effect, allowing the liquid to flow more orderly in the tower.
