Description

Technical Field

[0001] This invention relates to the field of heptamethyltrisiloxane hydrolysis reactor preparation technology, specifically a gas collection device for the heptamethyltrisiloxane hydrolysis reactor preparation process. Background Technology

[0002] The heptamethyltrisiloxane hydrolysis reactor is the core equipment used in the heptamethyltrisiloxane hydrolysis reaction, while the gas collection device in the preparation process of the heptamethyltrisiloxane hydrolysis reactor is an environmental protection supporting equipment in the heptamethyltrisiloxane hydrolysis process. It achieves waste gas purification and resource recovery through multi-stage treatment such as closed collection, staged condensation, absorption tower treatment, and activated carbon adsorption. Its function is to treat the acidic, alkaline and organic gases generated during the hydrolysis process.

[0003] In existing technologies, when the gas collected in the gas collection device during the preparation of heptamethyltrisiloxane hydrolysis reactor enters the absorption tower for treatment, the absorbent is mostly sprayed through a spray mechanism to make the absorbent come into contact with the waste gas, so that the absorbent reacts with the waste gas and purifies the waste gas. Since most spray mechanisms are fixed, the fixed spray head is prone to forming local "dry zones", which leads to gas short circuit and reduced absorption efficiency. Moreover, under the fixed spray head, the gas-liquid contact is mainly laminar flow, and the mass transfer resistance is large. Summary of the Invention

[0004] The purpose of this invention is to address the problem that, during the preparation of heptamethyltrisiloxane in a hydrolysis reactor, the gas collected in the gas collection device enters the absorption tower for treatment. In most cases, the absorbent is sprayed through a spray mechanism to contact the waste gas, causing a reaction and purification. However, since most spray mechanisms are fixed, localized "dry zones" easily form at the fixed spray heads, leading to gas short-circuiting, reduced absorption efficiency, and laminar flow with fixed spray heads resulting in high mass transfer resistance. Therefore, this invention proposes a gas collection device for the preparation of heptamethyltrisiloxane in a hydrolysis reactor.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The ring rack five meshes with a set of gears one, causing the rotation of the set of gears one to drive the ring rack five to rotate. Because the ring rack five meshes with the set of gears five, the rotation of the ring rack five drives the rotation of the set of gears five, which in turn drives the rotation of the set of nozzles three. The rotation directions of the set of nozzles three and the set of nozzles two are opposite, so that when the set of nozzles three and the set of nozzles two spray the absorbent liquid, the spraying can be more uniform, further reducing the spray dead angle, thereby further improving the absorption efficiency and allowing the absorbent liquid to contact the gas more evenly.

[0017] 2. A second sprocket is fixed to the top of the outer wall of the reciprocating column, and the second sprocket and a pair of first sprockets are connected by a chain. When the motor drives the rotating shaft, the first sprocket, and the chain to rotate, the second sprocket also rotates, causing the reciprocating column to rotate. The rotation of the reciprocating column causes the activated carbon adsorption layer to move up and down. This up-and-down movement of the activated carbon adsorption layer changes its contact position with the gas, forcing the gas to flow through different areas, avoiding localized penetration, and ensuring that all activated carbon particles fully participate in adsorption. This breaks the fixed path of gas flow, achieving uniform adsorption. During the movement, the activated carbon particles rub against each other, breaking the stacked structure, reducing the dead zone area, and lowering the bed pressure drop.

[0028] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1:

[0030] Please see Figures 1-8As shown, a gas collection device for the preparation of heptamethyltrisiloxane in a hydrolysis reactor includes a base 1; a staged condenser 2 is provided at the top of the outer wall of the base 1; a sealed collection pipe 3 is provided on one side of the outer wall of the staged condenser 2; an absorption shell 4 and an adsorption tower 5 are provided at the top of the outer wall of the base 1; the absorption shell 4, the staged condenser 2, and the adsorption tower 5 are connected to each other by a pair of second pipes; a pump body 6 is provided at the top of the outer wall of the absorption shell 4; the input end of the pump body 6 is connected to the bottom end of the absorption shell 4 through a third pipe, and the output end is connected to the top end of the absorption shell 4 through a fourth pipe; a connecting pipe 7 is fixedly connected to the top of the inner wall of the absorption shell 4, and the connecting pipe 7 is connected to the fourth pipe; a liquid is fixedly connected to the bottom of the outer wall of the connecting pipe 7. The liquid shell 8 has a nozzle 9 at the center of the bottom of its outer wall; a set of nozzles 10 is provided on the outer side of the bottom of the liquid shell 8; a gear 11 is fixedly connected to the outer side of the nozzle 10; an annular rack 12 is slidably connected to the inner side of the absorption shell 4 through a pair of arc-shaped blocks, and the annular rack 12 meshes with the gear 11; a rotating rod 13 is rotatably connected to the top of the outer wall of the absorption shell 4, and the bottom of the outer wall of the rotating rod 13 extends into the absorption shell 4; a gear 14 is fixedly connected to the outer side of the end of the rotating rod 13 inside the absorption shell 4, and the gear 14 meshes with the annular rack 12; a motor 15 is fixedly connected to the top of the outer wall of the base 1 through a support column; a rotating shaft 16 is fixedly connected to the output end of the motor 15. Both the top of the outer walls of the rotating shaft 16 and the rotating rod 13 are fixedly connected to sprockets 17, and the pair of sprockets 17 are connected by a chain 18. Gas from the preparation process of heptamethyltrisiloxane hydrolysis is collected through the sealed collection pipe 3 and transported to the staged condensation equipment 2 for staged condensation. The condensed gas is then transported to the absorption shell 4 through the second pipe between the absorption shell 4 and the staged condensation equipment 2. At this time, the motor 15 drives the rotating shaft 16 to rotate. Because both the top of the outer walls of the rotating shaft 16 and the rotating rod 13 are fixedly connected to sprockets 17, and the pair of sprockets 17 are connected by a chain 18, the rotating shaft 16 drives the rotating rod 13 to rotate through the sprockets 17 and the chain 18. The rotating rod 13 drives the gear 14 to rotate. Gear 14 meshes with ring rack 12, causing gear 14 to drive ring rack 12 to rotate. Since ring rack 12 meshes with a set of gears 11, the rotation of ring rack 12 drives gear 11 to rotate, which in turn drives a set of nozzles 10 to rotate. The set of nozzles 10 rotates while spraying absorbent liquid, thereby increasing the spraying range, reducing spray dead zones, and making it less likely to form local "dry zones" when spraying absorbent liquid, which would cause gas short circuits, thus improving absorption efficiency. When the sprayed absorbent liquid falls to the bottom of the absorption shell 4, pump body 6 sucks it up through the third pipe and then transports the absorbent liquid to the connecting pipe 7 through the fourth pipe, so that the absorbent liquid can be recycled, making the device more environmentally friendly.

[0031] A reciprocating shaft 30 is fixedly connected to the bottom of the outer wall of the rotating rod 13; a filter separation plate 31 is provided on the outer wall of the reciprocating shaft 30; the outer wall of the filter separation plate 31 is slidably connected to the inner wall of the absorption shell 4; a connecting plate is located above the gear 19; a baffle 32 is rotatably connected to the outer wall of a set of rotating rods 23, and the baffle 32 is located above a set of gears 25. When the rotating rod 13 rotates, the rotating rod 13 drives the reciprocating shaft 30 to rotate, and the reciprocating shaft 30 drives the filter separation plate 31 to move up and down reciprocally. When the absorbent liquid comes into contact with the gas and falls onto the filter separation plate 31, the filter separation plate 31 filters the impurities contained in the absorbent liquid, allowing the absorbent liquid to fall through the filter separation plate 31 to the bottom of the absorption shell 4. The filter is circulated through the pump body 6, and the up-and-down reciprocating motion of the filter separation plate 31 causes impurities to move along with it, preventing them from accumulating on the filter separation plate 31. This solves the problem of impurities clogging the filter separation plate 31 and causing a gradual decrease in filtration efficiency, resulting in better filtration efficiency of the filter separation plate 31. Furthermore, the baffle 32 is located above a set of gears 4 25, blocking the set of gears 4 25. The connecting plate 1 is located above gear 3 19, protecting gear 3 19. This prevents gears 4 25 and gear 3 19 from being contaminated with absorbent liquid, reducing absorbent liquid waste and increasing the service life of gears 4 25 and gear 3 19.

[0032] A gear 19 is fixedly connected to the outer wall of one end of the rotating rod 13 inside the absorption shell 4; a support plate 20 is fixedly connected to the inner wall of the absorption shell 4; a ring rack 21 is rotatably connected to the top of the outer wall of the support plate 20, and the ring rack 21 meshes with the gear 19; a square plate 22 is fixedly connected to the inner wall of the ring rack 21; a set of rotating rods 23 is rotatably connected to the top of the outer wall of the square plate 22; a set of fan blades 24 are fixedly connected to the outer walls of each set of rotating rods 23; a gear 25 is fixedly connected to the outer walls of each set of rotating rods 23; a ring rack 26 is fixedly connected to the inner wall of the absorption shell 4 through a connecting plate, and the ring rack 26 meshes with the gear 25. When the rotating rod 13 rotates, it drives the gear 19 to rotate. Because the ring rack 21 meshes with the gear 19, the gear 19 drives the ring rack. The rotation of rack 21 causes the square plate 22, a set of rotating rods 23, and gears 25 to rotate. Since the ring rack 26 and the set of gears 25 mesh with each other and the ring rack 26 is fixed, the rotation of the outermost gear 25 causes the ring rack 26 to rotate, which in turn drives the other gears 25 to rotate. This rotation of the set of gears 25 drives the rotating rods 23 and their blades 24 to rotate. The blades 24 rotate with the ring rack 21 while blowing air, which is directed at the gas and the sprayed absorbent liquid entering the absorption shell 4. This increases the contact area between the gas and the liquid, improving the absorption efficiency. The airflow disturbance generated by the blades 24 also ensures that the gas is evenly distributed within the absorption shell 4, preventing localized high concentrations.

[0033] An outlet pipe 41 is provided at the top of the outer wall of the adsorption tower 5; a reciprocating column 42 is rotatably connected to the top of the outer wall of the adsorption tower 5, and the bottom end of the outer wall of the reciprocating column 42 extends into the adsorption tower 5; a sprocket 43 is fixedly connected to the top of the outer wall of the reciprocating column 42, and the sprocket 43 and a pair of sprockets 17 are connected by a chain 18; an activated carbon adsorption layer 44 is slidably connected to the inner wall of the adsorption tower 5, and the activated carbon adsorption layer 44 matches the reciprocating column 42. The sprocket 43 is fixedly connected to the top of the outer wall of the reciprocating column 42, and the sprocket 43 and a pair of sprockets 17 are connected by a chain 18, so that the motor 15 drives the rotating shaft 16, the sprockets 17 and the chain 18. When strip 18 rotates, it simultaneously drives sprocket 2 43 to rotate, which in turn drives reciprocating column 42 to rotate. The rotation of reciprocating column 42 causes activated carbon adsorption layer 44 to move up and down reciprocally. This up-and-down movement of activated carbon adsorption layer 44 continuously changes its contact position with the gas, forcing the gas to flow through different areas, avoiding localized penetration, and ensuring that all activated carbon particles fully participate in adsorption. This breaks the fixed path of gas flow, achieving uniform adsorption. Furthermore, during the movement, the activated carbon particles rub against each other, breaking the stacked structure, reducing the dead zone area, and lowering the bed pressure drop.

[0034] A bevel gear 33 is slidably connected to the outer wall of the reciprocating shaft 30, and the bottom end of the outer wall of the bevel gear 33 is rotatably connected to the top end of the outer wall of the filter separation plate 31. A reciprocating rod 34 is rotatably connected to the top end of the outer wall of the filter separation plate 31 via a block. A bevel gear 35 is fixedly connected to one end of the outer wall of the reciprocating rod 34, and the bevel gear 35 meshes with the bevel gear 33. A reciprocating plate 36 is provided on the outer wall of the reciprocating rod 34. The bottom end of the outer wall of the reciprocating plate 36 is in contact with the top end of the outer wall of the filter separation plate 31. When the reciprocating shaft 30 rotates, the reciprocating shaft 30 drives the bevel gear 33. The bevel gear 33 rotates, and because the bevel gear 33 is connected to the top of the outer wall of the filter separation plate 31, the bevel gear 33 rotates while moving up and down with the filter separation plate 31. When the bevel gear 33 rotates, it drives the bevel gear 35 to rotate, which in turn drives the reciprocating rod 34 to rotate. The rotation of the reciprocating rod 34 drives the reciprocating plate 36 to reciprocate. The reciprocating motion of the reciprocating plate 36 cleans the impurities on the filter separation plate 31, thereby further preventing the impurities from clogging the filter separation plate 31 and allowing the filter separation plate 31 to operate better.

[0035] A set of nozzles 27 is provided at the bottom of the outer wall of the liquid shell 8, and the set of nozzles 27 is located between nozzle 10 and nozzle 9; gears 28 are fixedly connected to the outer walls of the set of nozzles 27; a ring rack 29 is rotatably connected to the bottom of the outer wall of the liquid shell 8; the ring rack 29 meshes with the set of gears 28, and the ring rack 29 meshes with a set of gears 11. When the set of gears 11 rotates, the meshing of the ring rack 29 with the set of gears 11 causes the rotation of the set of gears 11 to drive the ring rack 28. When rack 5 29 rotates, it meshes with a set of gears 5 28, causing the gears 5 28 to rotate. The gears 5 28 then drive the nozzles 3 27 to rotate. The nozzles 3 27 and the nozzles 2 10 rotate in opposite directions. This allows the nozzles 3 27 to spray the absorbent liquid more evenly and further reduces spray dead zones, thereby improving absorption efficiency and ensuring more uniform contact between the absorbent liquid and the gas.

[0036] The activated carbon adsorption layer 44 includes an annular plate 441 and a circular adsorption layer 442; the outer wall of the circular adsorption layer 442 is rotatably connected to the inner wall of the annular plate 441; an annular rack 8 45 is fixedly connected to the top of the outer wall of the circular adsorption layer 442; a gear 8 46 is slidably connected to the outer wall of the reciprocating column 42, and the bottom end of the outer wall of the gear 8 46 is rotatably connected to the top of the outer wall of the annular plate 441; the gear 8 46 and the annular rack 8 45 mesh with each other. When the reciprocating column 42 rotates, the activated carbon adsorption layer 44, including the annular plate 441 and the circular adsorption layer 442, drives the gear 8 46 to rotate. Because the gear 8 46 is rotatably connected to the annular plate 441, the gear 8 46 rotates while moving up and down with the annular plate 441. During rotation, the meshing of gear 846 and ring rack 845 causes gear 846 to rotate, which in turn drives ring rack 845 to rotate, causing the circular adsorption layer 442 to rotate. This causes the circular adsorption layer 442 to move up and down while rotating. The up-and-down movement forces the gas to flow through different height areas, avoiding localized penetration. The rotation, through centrifugal force, causes the gas to form a spiral flow within the adsorption layer, further extending the contact path and making the adsorption amount in each area of ​​the circular adsorption layer 442 more uniform, avoiding localized saturation. At the same time, the centrifugal force disperses the gas distribution, reducing the dead zone area. Through the combined motion of up-and-down reciprocating motion and rotation, this device improves the adsorption efficiency of the circular adsorption layer 442 while extending its service life.

[0037] The reciprocating plate 36 is in the shape of a right triangle; a connecting shell 37 is fixed to one side of the inner wall of the absorption shell 4; a sliding plate 38 is fixed to one side of the inner wall of the connecting shell 37 by a spring, and the sliding plate 38 matches the reciprocating plate 36; a square through groove 39 is opened at the top of the outer wall of the filter separation plate 31; a recovery shell 40 is provided at the bottom of the outer wall of the filter separation plate 31, and the recovery shell 40 is connected to the square through groove 39. When the reciprocating plate 36 moves to the sliding plate 38, the reciprocating plate 36 continues to move and will abut against the sliding plate 38, causing the sliding plate 38 to drive the spring to contract. At this time, the sliding plate 38 will also move along the inclined surface of the reciprocating plate 36 to scrape the impurities on the inclined surface of the reciprocating plate 36. The impurities are scraped to one side of the reciprocating plate 36. At this time, the reciprocating plate 36 moves towards the square channel 39, pushing the impurities until they fall into the recovery shell 40 through the square channel 39 and are collected. This collection and storage of impurities facilitates their recovery and also prevents the large number of impurities from affecting the separation efficiency of the filter plate 31. Furthermore, the position of the connecting shell 37 blocks the bevel gears 7 35 and 6 33, preventing the absorbent liquid from falling onto them. This increases the service life of the bevel gears 6 33 and 7 35 while reducing the waste of absorbent liquid.

[0038] Example 2:

[0039] Please see Figures 7-8As shown, the top of the outer wall of the annular plate 441 is fixedly connected to an annular rack 47 via a connecting plate 9; the top of the outer wall of the circular adsorption layer 442 is rotatably connected to a rotating rod 48 via a set of blocks 9; one end of the outer wall of the rotating rod 48 is fixedly connected to a gear 49, and all of the gears 49 mesh with the annular rack 47; a set of flexible rods 50 is fixedly connected to the outer wall of the rotating rod 48; one end of the outer wall of the flexible rods 50 is fixedly connected to a vibrating ball 51, which is connected to the rotating rod 50 via a set of blocks 9. The nine-axis mechanism drives a set of rotating rods 48 to rotate, which in turn drives a set of gears 49 to rotate. Since all gears 49 mesh with the ring rack 47, and the ring rack 47 is fixed, the rotation of the gears 49 causes the ring rack 47 to rotate, which in turn drives the rotating rods 48 to rotate. The rotating rods 48 then drive the flexible rod 50 and the vibrating ball 51 to rotate, causing the vibrating ball 51 to strike the circular adsorption layer 442, causing the circular adsorption layer 442 to vibrate. The vibrating ball 51 periodically impacts the active... The carbon layer generates high-frequency micro-vibrations, causing gas to form turbulence and further disrupting the laminar boundary layer. This completely breaks the path dependence of gas flow, allowing the activated carbon in the circular adsorption layer 442 to uniformly contact the gas. This solves part of the problem of low activated carbon utilization, reducing activated carbon waste and extending the service life of the circular adsorption layer 442. Furthermore, the high-frequency vibration causes adsorbate molecules within the activated carbon pores to undergo desorption-readsorption cycles, dynamically renewing the pore surface, avoiding local saturation, reconstructing the dynamic pore structure, eliminating dead zones and short circuits, and generating a "micro-convection" effect that enhances the external diffusion process. This increases the relative velocity between the gas and activated carbon, thereby strengthening the mass transfer process, shortening the adsorption equilibrium time, and improving the mass transfer coefficient. Thus, through multiple composite movements of reciprocating motion, rotation, and vibration, this device improves the adsorption efficiency of the circular adsorption layer 442, extends the activated carbon replacement cycle, increases the mass transfer coefficient, and reduces operating costs.

[0040] In use, the gas produced during the hydrolysis of heptamethyltrisiloxane is collected through the sealed collection pipe 3 and transported to the staged condensation device 2 for staged condensation. The condensed gas is then transported to the absorption shell 4 through the second pipe between the absorption shell 4 and the staged condensation device 2. At this time, the motor 15 drives the rotating shaft 16 to rotate. Since the top of the outer wall of both the rotating shaft 16 and the rotating rod 13 are fixedly connected to sprockets 17, and a pair of sprockets 17 are connected by a chain 18, the rotating shaft 16 drives the rotating rod 13 to rotate through the sprockets 17 and the chain 18. Rotating rod 13 drives gear 14 to rotate. Since gear 14 meshes with ring rack 12, it drives the ring rack 12 to rotate. Since the ring rack 12 meshes with a set of gears 11, the rotation of the ring rack 12 drives the set of gears 11 to rotate, which in turn drives a set of nozzles 10 to rotate. The set of nozzles 10 rotates while spraying absorbent liquid, thereby increasing the spraying range, reducing spray dead zones, and making it less likely to form local "dry areas" when spraying absorbent liquid, which would cause gas short circuits, thus improving absorption efficiency.

[0041] When the sprayed absorbent falls to the bottom of the absorbent shell 4, the pump body 6 draws it in through the third pipe and then transports the absorbent to the connecting pipe 7 through the fourth pipe, so that the absorbent can be recycled and the device can be made more environmentally friendly.

[0042] When the rotating rod 13 rotates, it drives the gear 19 to rotate. Because the ring rack 21 meshes with the gear 19, the gear 19 drives the ring rack 21 to rotate. The ring rack 21 then drives the square plate 22, a set of rotating rods 23, and the gear 25 to rotate. Because the ring rack 26 meshes with the set of gears 25, and the ring rack 26 is fixed, when the outermost gear 25 rotates, it rotates through the ring rack 26. The rotation of the side gear 4 25 drives the rotation of other gears 4 25, thus causing a set of gears 4 25 to rotate, which in turn drives a set of rotating rods 1 23 and the fan blades 24 of the rotating rods 1 23 to rotate. The fan blades 24 rotate with the ring rack 3 21 while blowing air, which blows the air onto the gas and the sprayed absorbent liquid delivered into the absorption shell 4, increasing the contact area between the gas and the liquid, improving the absorption efficiency, and the airflow disturbance generated by the fan blades 24 makes the gas evenly distributed in the absorption shell 4, avoiding the occurrence of excessively high local concentrations.

[0043] When a set of gears 11 rotates, the ring rack 29 meshes with it, causing the ring rack 29 to rotate. The ring rack 29 meshes with a set of gears 28, causing the gears 28 to rotate, which in turn drives the nozzles 27 to rotate. The nozzles 27 and 20 rotate in opposite directions, allowing for more even spraying of the absorbent liquid and reducing dead zones. This improves absorption efficiency and ensures more uniform contact between the absorbent liquid and the gas.

[0044] When the rotating rod 13 rotates, it drives the reciprocating shaft 30 to rotate. The reciprocating shaft 30 drives the filter separation plate 31 to move up and down reciprocally. When the absorbent liquid comes into contact with the gas and falls onto the filter separation plate 31, the filter separation plate 31 filters out the impurities contained in the absorbent liquid. The absorbent liquid then falls through the filter separation plate 31 to the bottom of the absorption shell 4 and is circulated by the pump body 6. The up-and-down reciprocating motion of the filter separation plate 31 causes the impurities to move along with it, preventing them from accumulating in the filter. The filter separation plate 31 solves the problem of impurities clogging the filter separation plate 31 and causing the filtration efficiency to gradually decrease, thus making the filtration efficiency of the filter separation plate 31 better. Furthermore, the baffle 32 is located above a set of gears 25, which blocks the set of gears 25. The connecting plate is located above gear 19, which protects gear 19. This makes it less likely for the set of gears 25 and gear 19 to be contaminated with absorbent liquid, reducing absorbent liquid waste and increasing the service life of gears 25 and gear 19.

[0045] When the reciprocating shaft 30 rotates, it drives the bevel gear 6 33 to rotate. Since the bevel gear 6 33 is connected to the top of the outer wall of the filter separation plate 31, the bevel gear 6 33 rotates and moves up and down with the filter separation plate 31. When the bevel gear 6 33 rotates, it drives the bevel gear 7 35 to rotate, which in turn drives the reciprocating rod 34 to rotate. The rotation of the reciprocating rod 34 drives the reciprocating plate 36 to reciprocate. The reciprocating motion of the reciprocating plate 36 cleans the impurities on the filter separation plate 31, thereby further preventing the impurities from clogging the filter separation plate 31 and allowing the filter separation plate 31 to operate better.

[0046] When the reciprocating plate 36 moves to the sliding plate 38, the reciprocating plate 36 continues to move and will block the sliding plate 38, causing the sliding plate 38 to drive the spring to contract. At this time, the sliding plate 38 will also move along the inclined surface of the reciprocating plate 36, scraping the impurities on the inclined side of the reciprocating plate 36 until the impurities are scraped to the straight side of the reciprocating plate 36. At this time, the reciprocating plate 36 moves towards the square through groove 39, pushing the impurities until the impurities fall through the square through groove 39 into the recovery shell 40 and are collected. This collection and storage of impurities facilitates their recovery and also prevents the separation efficiency of the filter separation plate 31 from being affected when the amount of impurities is large. Furthermore, the position of the connecting shell 37 blocks the bevel gears 7 35 and 6 33, preventing the absorbent liquid from falling onto the bevel gears 6 33 and 7 35. This increases the service life of the bevel gears 6 33 and 7 35 while reducing the waste of absorbent liquid.

[0047] After the gas reacts with the absorbent liquid and is purified, the purified gas is transported to the adsorption tower 5 through the second pipe between the absorbent shell 4 and the adsorption tower 5.

[0048] When gas enters the adsorption tower 5, a sprocket 43 is fixed to the top of the outer wall of the reciprocating column 42. The sprocket 43 and a pair of sprockets 17 are connected by a chain 18. When the motor 15 drives the rotating shaft 16, sprockets 17 and chain 18 to rotate, it also drives sprocket 43 to rotate. The sprocket 43 drives the reciprocating column 42 to rotate. The rotation of the reciprocating column 42 causes the activated carbon adsorption layer 44 to move up and down. Because the activated carbon adsorption layer 44 moves up and down, it constantly changes its contact position with the gas, forcing the gas to flow through different areas, avoiding local penetration, and ensuring that all activated carbon particles fully participate in adsorption. This breaks the fixed path of gas flow, achieves uniform adsorption, and during the movement, the activated carbon particles rub against each other, breaking the stacked structure, reducing the dead zone area, and reducing the bed pressure drop.

[0049] The activated carbon adsorption layer 44 includes an annular plate 441 and a circular adsorption layer 442. When the reciprocating column 42 rotates, it drives the gear 46 to rotate. Since the gear 46 is rotatably connected to the annular plate 441, the gear 46 rotates while moving up and down with the annular plate 441. When the gear 46 rotates, it meshes with the annular rack 45, causing the annular rack 45 to rotate, which in turn drives the circular adsorption layer 442 to rotate. The circular adsorption layer 442 moves up and down while rotating. The up and down movement forces the gas to flow through different height areas, avoiding local penetration. The rotation, through centrifugal force, causes the gas to form a spiral flow within the adsorption layer, further extending the contact path and making the adsorption amount in each area of ​​the circular adsorption layer 442 more uniform, avoiding local saturation. At the same time, the centrifugal force disperses the gas distribution, reducing the dead zone area. This device improves the adsorption efficiency of the circular adsorption layer 442 and extends its service life through the combined motion of up and down reciprocating motion and rotation.

[0050] When the circular adsorption layer 442 rotates, it drives a set of rotating rods 48 via a set of square blocks 9, which in turn drives a set of gears 49. Since all gears 49 mesh with an annular rack 47, and the annular rack 47 is fixed, the rotation of the gears 49 drives the rotating rods 48 via the rotation of the annular rack 47, which in turn drives the flexible rod 50 and the vibrating ball 51 to rotate. The vibrating ball 51 strikes the circular adsorption layer 442, causing it to vibrate. The vibrating ball 51 periodically impacts the activated carbon layer, generating high-frequency micro-vibrations, which create turbulence in the gas and further disrupt the laminar boundary layer. This completely breaks the path dependence of gas flow, allowing the activated carbon in the circular adsorption layer 442 to contact the gas uniformly. This solves part of the problem of low activated carbon utilization, thereby reducing activated carbon waste and extending the service life of the circular adsorption layer 442. Furthermore, high-frequency vibration causes the adsorbate molecules in the activated carbon pores to undergo desorption-readsorption cycles, dynamically renewing the pore surface, avoiding local saturation, reconstructing the dynamic pore structure, eliminating dead zones and short circuits, and generating a "micro-convection" effect from high-frequency vibration, which enhances the external diffusion process and increases the relative velocity between the gas and activated carbon. This strengthens the mass transfer process, shortens the adsorption equilibrium time, and improves the mass transfer coefficient.

[0051] After the gas is purified by adsorption by the circular adsorption layer 442, it is discharged to other equipment through the gas outlet pipe 41 for the next process or testing.

[0052] The internal structure of the adsorption tower 5 in this application improves the adsorption efficiency of the circular adsorption layer 442, extends the replacement cycle of activated carbon, increases the mass transfer coefficient, and reduces operating costs through multiple compound movements of reciprocating motion, rotation, and vibration. In addition, the spray mechanism, blower mechanism, and cleaning mechanism in the adsorption tower not only enable the absorbent liquid and gas to have more complete contact and reaction, but also reduce spray dead zones and properly collect and retain impurities generated after the reaction.
