Description

Technical Field

[0001] This invention relates to the field of chemical packing tower technology, specifically to an internal support structure for a corrosion-resistant chemical packing tower. Background Technology

[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 chemical, petroleum, and environmental protection fields. Corrosion-resistant chemical packed towers are specifically designed for corrosive media. Due to the highly corrosive nature of the media being processed, the tower body, packing, and internal components must all be made of corrosion-resistant materials, or enhanced with anti-corrosion coatings, linings, and other processes to ensure long-term stable operation. Their core characteristic is the large amount of packing material inside the tower, which increases the gas-liquid contact area through the packing surface, thereby enhancing mass transfer efficiency, such as in absorption and distillation processes.

[0003] In existing technologies, the internal support structure of a corrosive chemical packed tower refers to a component used to support the weight of the packing material, while also allowing the smooth passage of gas and liquid, and being corrosion-resistant itself. During use, the internal support structure of corrosive chemical packed towers mostly employs a hump support plate, with its top convex upwards and hollow interior. When a large amount of packing material is poured in, significant pressure is exerted on the hump support plate. Without internal support, the sides of the hump support plate are prone to denting, bending, and other deformations, damaging the support structure, affecting its support performance, and shortening its service life.

[0004] Therefore, we propose an internal support structure for a corrosion-resistant chemical packed tower to address the problems mentioned in the background section. Summary of the Invention

[0005] The purpose of this invention is to provide an internal support structure for a corrosive chemical packing tower, in order to solve the problem that, in the use of the aforementioned internal support structure for corrosive chemical packing towers, the interior is hollow, and when a large amount of packing is poured in, the lack of internal support makes the sides of the hump support plate easily subjected to pressure and extrusion, resulting in deformations such as dents and bends, which damages the support plate structure and affects its support performance.

[0013] Preferably, two limiting rods are movably embedded inside each of the two toothed plates, and the two ends of the four limiting rods are respectively fixedly installed on both sides inside the fixed cover. Two fixing plates are fixedly installed on the top and bottom of the fixed cover. Four support rods are fixedly installed on the opposite side of each of the two reinforcing support plates. Four movable holes are opened on one side of the outer surface of each of the four fixing plates. The multiple movable holes are divided into eight groups on average, and the outer surfaces of the eight support rods are respectively movably embedded inside the eight groups of movable holes.

[0014] Preferably, the outer surfaces of the plurality of reinforcing rods are movably embedded in the interior of the plurality of reinforcing rods, the inner walls of the two single-fork support plates and the two double-fork support plates are respectively in contact with the three corners inside the two stepped components, the tops of the two reinforcing support plates are respectively in contact with the two sides inside the tower tip component, one end of the rotating shaft is movably embedded in the rear surface wall inside the fixed cover, and one end of the rotating shaft movably extends through to the front surface of the fixed cover.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. In use, the C-shaped hook pulls the lever, pulling the limiting ratchet out of the I-shaped block and separating it from the annular ratchet. Rotating the turntable causes the rotating shaft, I-shaped block, annular ratchet, and anti-corrosion gear to rotate together, simultaneously causing the upper and lower toothed plates to move in opposite directions. This, via the connecting rod, pushes the two reinforcing support plates to move, causing the single-fork support plate and double-fork support plate to abut against the three corners inside the stepped component. The reinforcing rod enters the reinforcing groove, and the two reinforcing support plates abut against the tower tip component. Then, pushing the C-shaped hook downwards causes the limiting ratchet and annular ratchet to re-engage. This provides vertical support to the tower tip component while simultaneously reinforcing the two stepped components with diagonal supports, improving the overall structural strength and integrity of the stepped tower assembly, enhancing its resistance to compression and deformation, ensuring structural stability even under heavy loads, and extending its service life.

[0020] 2. In use, the support components of this invention are independent, detachable modules. Under different working conditions, factors such as the weight of the packing material inside the packed tower vary. The detachable and selectable number of support components facilitates individual replacement of damaged parts and allows for flexible adjustment of support strength according to actual working conditions. Move the retaining shaft to the C-hook, then move the tool lever to the right so that the retaining shaft enters the C-hook. Pushing the tool lever upwards simultaneously lifts multiple C-hooks and pulls multiple limiting ratchet teeth out of the annular ratchet. This eliminates the need to pull each C-hook individually, significantly saving disassembly time and steps when disassembling multiple support components, improving disassembly efficiency, and making the process more convenient.

[0021] 3. In use, the stepped components of this invention feature a gentle, curved stepped shape, resulting in more continuous and smooth gas-liquid flow, reducing flow resistance and energy loss. Simultaneously, it increases the gas-liquid contact path length, which is beneficial for improving mass transfer efficiency. The pointed-corner tower tip component guides the gas-liquid flow to both sides, working in conjunction with the stepped components on both sides to ensure a more orderly distribution of fluid across the entire tower cross-section. The inclined holes are tilted towards the inner wall of the tower, which helps guide the gas-liquid to the vicinity of the inner wall, improving the gas-liquid distribution in the edge areas and allowing the edge packing to fully participate in the mass transfer process.

[0022] 4. In use, the bottom guide assembly provides auxiliary support to the stepped tower assembly, increasing its overall load-bearing capacity. Simultaneously, the radial guide plates form radial strip supports, providing excellent guidance and allowing the liquid to flow more orderly within the tower. In particular, it effectively guides the liquid to the edge areas, increasing the liquid velocity there, reducing liquid stagnation, and promoting better gas-liquid contact. The conical nails help to disperse the fluid, creating multiple flow paths for more complete contact and reaction. Attached Figure Description

A third sealing ring 425 is fixedly connected to the inner wall of each of the third sealing holes 424.The outer surface of the pull rod 422 contacts the inner wall of the third sealing ring 425. The outer surface of the limiting ratchet 421 is movably embedded in the interior of the I-shaped block 416. Two limiting rods 414 are movably embedded in the interior of each of the two toothed plates 410. The two ends of the four limiting rods 414 are respectively fixedly installed on both sides inside the fixed cover 404. Two fixed plates 406 are fixedly installed on the top and bottom of the fixed cover 404. Four support rods 407 are fixedly installed on the opposite side of each of the two reinforcing support plates 401.

The outer surfaces of the eight support rods 407 are movably embedded in the interior of the eight groups of movable holes 428. The outer surfaces of the multiple reinforcing rods 405 are movably embedded in the interior of the multiple reinforcing rods 405. The inner walls of the two single-fork support plates 402 and the two double-fork support plates 403 are... The two reinforcing support plates 401 contact the three corners inside the two stepped components 302 respectively. The tops of the two reinforcing support plates 401 contact the two sides inside the tower tip component 301 respectively. One end of the rotating shaft 409 is movably embedded in the rear surface wall inside the fixed cover 404, and the other end of the rotating shaft 409 movably extends to the front surface of the fixed cover 404. The auxiliary tool assembly 5 includes a tool rod 501. Multiple threaded grooves 502 are opened on the top surface of the outer surface of the tool rod 501. An L-shaped rod 503 is threadedly embedded in the internal threads of the threaded grooves 502. A retaining shaft 504 is fixedly installed at one end of the L-shaped rod 503.

[0039] In this embodiment, during use, a stepped tower assembly 3 of a corresponding size is selected according to the internal dimensions of the first support frame 1 and installed in the first support frame 1. Adjacent stepped tower assemblies 3 are fixedly connected together to form a complete stepped 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. Multiple reinforcing slots 305 are formed at the three corners inside the two stepped components 302, with five reinforcing slots 305 forming a group, and multiple groups of reinforcing slots 305 are provided. The single-fork support plate 402 has one arc-shaped fork, the double-fork support plate 403 has two arc-shaped forks, and one side of each reinforced support plate 401 has three arc-shaped forks. Five reinforcing rods 405 are installed on the inner wall of each arc-shaped fork, forming three groups of five. The positions of the three groups of reinforcing rods 405 correspond to the three groups of reinforcing slots 305 at different positions at the three corners inside the stepped component 302. The initial positions of the two reinforced support plates 401 are close to both sides of the fixed cover 404. By pulling the pull rod 422 upward by the C-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 is no longer fixed, and the rotating shaft 409 becomes movable. Place the support assembly 4 inside the stepped tower assembly 3, aligning the three sets of reinforcing rods 405 on both sides with the corresponding reinforcing grooves 305. Then rotate the turntable 415, causing the rotating shaft 409, I-beam block 416, annular ratchet 417, and anti-corrosion gear 408 to rotate together. Simultaneously, the upper and lower toothed plates 410 move in opposite directions, pushing the connecting rod 411 to move, thus pushing the two reinforcing support plates 401 to the sides, and simultaneously pushing the single-fork support plate 402 and double-fork support plate 403 towards the corners inside the stepped component 302. When the single-fork support plate 402 and double-fork support plate 403 respectively abut against the three corners inside the stepped component 302, the reinforcing rods 405 simultaneously enter the reinforcing grooves 305, and the tops of the two reinforcing support plates 401 abut against the two sides inside the tower tip component 301, as shown. Figure 5 and Figure 7As shown. Then, stop rotating the turntable 415 and push the C-hook 426 downward. The limit ratchet 421 is pushed back into the I-shaped block 416 by the pull rod 422, and it engages with the ring ratchet 417 again, thereby fixing the rotated shaft 409 and preventing the anti-corrosion gear 408 from rotating on its own, which would affect the clamping and supporting force of the reinforcing support plate 401, the single fork support plate 402, and the double fork support plate 403 on the stepped tower assembly 3. The number of support assemblies 4 can be selected according to the stepped tower assembly 3 of different lengths, and they 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 tip component 301, providing vertical support force. The single-fork support plate 402 and double-fork support plate 403 provide diagonal support and reinforcement to the inner walls of the two stepped components 302, effectively distributing the weight of the packing and other external forces, and dispersing the pressure to other support structures. This improves the overall structural strength and integrity of the stepped tower assembly 3, enhances its resistance to pressure and deformation, ensures structural stability when bearing a large amount of packing, and extends its service life. This solves the problem that when the internal support structure of the corrosive chemical packing tower is hollow, the lack of internal support when a large amount of packing is poured in can easily cause the hump support plate to be squeezed by pressure, resulting in dents, bending and other deformations, which damages the support plate structure and affects its support performance.

[0040] Furthermore, the support component 4 is designed as an independently detachable module. Under different operating conditions, factors such as the weight of the packing material inside the packed tower vary. By using detachable support components 4 and selecting the number as needed, the support strength can be flexibly adjusted according to the actual operating conditions. Moreover, the installation positions of the reinforcement groove 305 and the support component 4 do not affect the flow hole 303, meaning that the increased strength and load-bearing capacity of the internal support structure do not affect the normal operation of the packed tower.

[0041] Furthermore, by repeating the installation process of the support component 4, the reinforcing 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. At the same time, the reinforcing rod 405 can be moved out of the reinforcing groove 305, and the individual support component 4 can be removed. The detachable design makes it easy to replace the damaged parts individually without removing the entire support plate, thus reducing maintenance difficulty and cost.

[0042] 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 components 4, six L-shaped rods 503 at corresponding positions are threadedly connected through threaded grooves 502. The tool rod 501 is moved to the bottom of the fixed cover 404, and the L-shaped rods 503 and retaining pins 504 are moved to the C-hooks 426. Then, the tool rod 501 is moved to the right, causing all six retaining pins 504 to move into the C-hooks 426. The tool rod 501 is then pushed upwards, causing the six L-shaped rods 503 to move the six retaining pins 504 upwards simultaneously, thus simultaneously pushing the six C-hooks 426 upwards. This simultaneously pulls the six limiting ratchet teeth 421 out of the annular ratchet teeth 417. Finally, the worker only needs to rotate the turntable 415 in reverse order to remove multiple support components 4 from inside the stepped tower assembly 3, without having to pull each C-hook 426 individually. This significantly saves disassembly time and steps, improves disassembly efficiency, and makes disassembly more convenient when removing multiple support components 4.

[0043] Example 2: Figure 1 , Figure 5 and Figure 7 As shown, a bottom guide component 2 is provided at the bottom of the first support frame 1, a stepped tower component 3 is provided inside the first support frame 1, and a support component 4 is provided inside the stepped tower component 3; the stepped tower component 3 includes a tower tip component 301, and stepped components 302 are fixedly installed on both sides of the bottom of the tower tip component 301. Multiple reinforcing grooves 305 are provided at the three corners inside the two stepped components 302. Multiple flow holes 303 are provided on the outer surfaces of both sides of the tower tip component 301 and the top of the two stepped components 302. Multiple inclined holes 304 are provided at the two corners of the outer surfaces of the two stepped components 302. The cross-section of the two stepped components 302 is stepped, and the corners of the outer surfaces of the two stepped components 302 are curved. The outer surface of the stepped tower component 3 is fixedly installed on the inner wall of the first support frame 1.

[0044] In this embodiment, during use, the stepped tower assembly 3 features a pointed center and curved stepped designs on both sides. This stepped structure alters 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 resulting in a more uniform distribution throughout the packing layer. The stepped component 302 has a gentle curved stepped shape, making the gas-liquid flow more continuous and smooth, reducing flow resistance and energy loss, while increasing the gas-liquid contact path length, which is beneficial for improving mass transfer efficiency. The pointed tower tip component 301 guides the gas-liquid flow to both sides, working in conjunction with the stepped components 302 on both sides to ensure a more orderly distribution of fluid across the entire tower cross-section, preventing excessive fluid concentration in the central area. The inclined holes 304 are inclined towards the inner wall of the tower, which helps guide the gas-liquid to the vicinity of the inner wall, improving the gas-liquid distribution in the edge areas, allowing the edge packing to fully participate in the mass transfer process, and improving the overall mass transfer uniformity of the tower. All structural components involved in this internal support structure are made of corrosion-resistant materials.

[0045] Example 3: Figures 2-4 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, and a support assembly 4 is provided inside the stepped tower assembly 3. The bottom guide assembly 2 includes a second support frame 201. A mounting bracket 202 is fixedly installed on the top surface inside the second support frame 201. Multiple radial guide plates 203 are bolted to the outer surface of the bottom of the mounting bracket 202. Multiple conical nails 204 are fixedly installed on the top and bottom of the multiple radial guide plates 203. One side of the outer surface of the multiple radial 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. The first support frame 1 and the second support frame 201 are connected by bolts.

[0046] In this embodiment, during use, the bottom of the stepped tower assembly 3 is bolted to the bottom guide assembly 2. The bottom guide assembly 2 provides auxiliary support to the stepped tower assembly 3, increasing its overall load-bearing capacity and ensuring overall structural strength. Multiple radial guide plates 203 are installed in the second support frame 201, arranged radially, with the channel width gradually increasing from the center to the edge. These radially arranged strip supports have excellent guiding properties, directing liquid flowing from the central region to the edge channels, preventing liquid from flowing off course or accumulating in the central region. This guiding effect allows the liquid to flow more orderly within the tower, effectively guiding it to the edge regions, increasing the liquid velocity in the edge regions, reducing liquid stagnation, and promoting better gas-liquid contact. Multiple conical nails 204 are installed at the top and bottom of the radial guide plates 203, which helps to force the fluid to disperse, forming multiple flow paths, thus ensuring more thorough contact and reaction.

[0047] The overall effect and working principle of the mechanism are as follows: the C-shaped hook 426 pulls the pull rod 422 upward, pulling the limiting ratchet 421 out of the I-shaped block 416 and separating it from the ring ratchet 417. The support assembly 4 is placed inside the stepped tower assembly 3, and the three sets of reinforcing rods 405 on both sides are aligned with the corresponding reinforcing grooves 305. Then, the turntable 415 is rotated, causing the rotating shaft 409, I-shaped block 416, ring ratchet 417 and anti-corrosion gear 408 to rotate together. At the same time, the upper and lower toothed plates 410 are moved in opposite directions. By pushing the connecting rod 411, the two reinforcing support plates 401 are pushed to both sides, and the single fork support plate 402 and double fork support plate 403 are pushed to move towards the corner inside the stepped component 302. When the single-fork support plate 402 and the double-fork support plate 403 abut against the three corners inside the stepped component 302, the reinforcing rod 405 simultaneously enters the reinforcing groove 305, and the tops of the two reinforcing support plates 401 abut against the two sides inside the tower tip component 301. Then, the C-shaped hook 426 is pushed downward, causing the limiting ratchet 421 to engage with the annular ratchet 417 again. At this time, the reinforcing support plates 401 support the two sides inside the tower tip component 301, providing vertical support force. The single-fork support plate 402 and the double-fork support plate 403 provide oblique support and reinforcement to the inner walls of the two stepped components 302, effectively distributing the weight of the filler and other external forces, and enhancing its 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 retaining shaft 504 to the C-shaped hook 426. Then move the tool rod 501 to the right so that all six retaining shafts 504 move into the C-shaped hooks 426. Then push the tool rod 501 upward so that the six L-shaped rods 503 drive the six retaining shafts 504 to move upward simultaneously, thus pushing the six C-shaped hooks 426 upward at the same time, which pulls the six limiting ratchet teeth 421 out of the annular ratchet teeth 417. Finally, the operator only needs to rotate the turntable 415 in reverse order to remove the multiple support components 4 from the inside of the stepped tower component 3. The tower tip component 301 with a sharp corner in the middle can guide the gas and liquid to flow to both sides. Together with the stepped components 302 on both sides, the fluid is more orderly distributed to the entire tower cross section. The stepped components 302 are in the shape of a gentle curved step, which makes the gas and liquid flow more continuous and gentle, reduces flow resistance and energy loss, and increases the gas-liquid contact path length, which is beneficial to improving mass transfer efficiency. The bottom guide assembly 2 provides auxiliary support for the stepped tower assembly 3, increasing the overall load-bearing capacity of the stepped tower assembly 3. At the same time, the radial guide plates 203 form radial strip support components, which have a good guiding effect, allowing the liquid to flow more orderly in the tower.
