Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, and in particular to a high-efficiency and low-energy-consumption industrial waste gas purification device. Background Art

[0002] Industrial waste gas contains a large amount of toxic gases, particulate matter, organic matter and other harmful substances. If it is directly discharged into the atmosphere, it will cause great pollution to the atmospheric environment. Therefore, in order to protect the ecological environment, it is necessary to purify industrial waste gas.

[0003] There are many ways to treat industrial waste gas, including absorption, which uses chemical absorbents to absorb harmful components in the waste gas to achieve the purpose of purification;

[0004] For example, a waste gas purification treatment device disclosed in the prior art can filter the waste gas in advance to remove large particles of impurities, and at the same time can rotate and spray the treatment liquid through the nozzle to improve the purification effect of the waste gas.

[0005] The above technology achieves the purification of exhaust gas through the filter and the nozzle, but there are still some shortcomings. Since the filter is arranged inside the intake pipe, and in order to avoid the filter from being blocked and to facilitate the cleaning of impurities, multiple components such as a scraper are arranged. Multiple components are arranged inside the intake pipe, which will greatly occupy the internal space of the intake pipe, hinder the intake, and cause the intake volume to be greatly reduced, which is not conducive to improving the working efficiency. At the same time, it also makes the internal structure of the intake pipe complicated, and the later maintenance is difficult;

[0006] The treatment liquid contacts the exhaust gas by spraying to achieve the purification effect. The treatment liquid needs to be sprayed in large quantities to ensure sufficient contact with the exhaust gas, resulting in a large consumption of the treatment liquid, which greatly increases the cost.

[0007] In summary, the current prior art still has defects and needs to be improved. Summary of the invention

[0008] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0009] Therefore, the object of the present invention is to provide an industrial waste gas purification device with high efficiency and low energy consumption, comprising a housing, and a filter assembly and an absorption assembly arranged in the housing, wherein one side of the housing is open and welded with a gas collecting hood, and the end surface of the gas collecting hood is provided with a through hole.

[0010] The filter assembly includes a separation cylinder, one side of which is open and movably connected to the first side plate bearing, a first sleeve is welded and connected at the center of the other side of the separation cylinder, a second sleeve is welded and connected at the center of the first side plate, and a plurality of slag collecting assemblies are arranged on the inner wall of the separation cylinder in an annular distribution.

[0011] The absorption assembly comprises an inner treatment cylinder and an outer treatment cylinder, the outer treatment cylinder is disposed outside the inner treatment cylinder, a second side plate and a third side plate are disposed on both sides of the inner treatment cylinder and the outer treatment cylinder, and part of the wall of the inner treatment cylinder and the outer treatment cylinder is located in a cleaning pool, and the cleaning pool is disposed at the bottom of the shell,

[0012] The first sleeve passes through the second side plate and is movably connected to the housing bearing, the second sleeve passes through the third side plate and is welded to the housing, an air inlet pipe is inserted into the first sleeve, one end of the air inlet pipe extends into the separation cylinder and is connected to the first air outlet strip;

[0013] The first side plate is penetrated by a first rotating rod connected to a bearing thereof, and the first side plate is penetrated by a collecting box welded to the first rotating rod.

[0014] Nylon bristles are evenly distributed on the first rotating rod, and the nylon bristles on the first rotating rod are in contact with the inner wall of the separation cylinder;

[0015] The third side plate is provided with a coating component for applying absorbent to the inner walls of the inner treatment cylinder and the outer treatment cylinder, and the third side plate is penetrated by two second rotating rods movably connected to their bearings, and nylon bristles are evenly distributed on the second rotating rods, and the nylon bristles on the two second rotating rods are in contact with the inner walls of the inner treatment cylinder and the outer treatment cylinder respectively.

[0016] As the preferred technical solution:

[0017] In the above-mentioned high-efficiency and low-energy consumption industrial waste gas purification device, the first sleeve is welded to the second side plate, the second sleeve is movably connected to the third side plate bearing, and the second side plate is fixedly bonded to the end faces of the inner treatment cylinder and the outer treatment cylinder.

[0018] Through the above technical solution, a motor is bolted to the side wall of the shell, and the motor is gear-connected to the first sleeve. Then, driven by the motor, the first sleeve will rotate axially, and then the second side plate and the separation cylinder will rotate accordingly, and the second side plate will drive the inner treatment cylinder and the outer treatment cylinder to rotate synchronously.

[0019] In the above-mentioned high-efficiency and low-energy consumption industrial waste gas purification device, the inner diameters of the separation cylinder, the inner treatment cylinder and the outer treatment cylinder gradually increase as they move inwards, and the three are coaxial.

[0020] The outer circular wall of the separation cylinder is in the shape of a screen, the outer circular walls of the inner treatment cylinder and the outer treatment cylinder are porous, and the holes on the inner treatment cylinder and the outer treatment cylinder are distributed in a staggered manner.

[0021] Through the above technical solution, the separation cylinder is made of stainless steel, and the inner treatment cylinder and the outer treatment cylinder are made of ceramic. The separation cylinder is used to separate the particulate matter in the exhaust gas. The inner treatment cylinder and the outer treatment cylinder can absorb the harmful components in the exhaust gas through the absorbent coated thereon, thereby achieving the purpose of purification.

[0022] In the above-mentioned high-efficiency and low-energy consumption industrial waste gas purification device, a gear is fixed to one end of the first rotating rod by a bayonet, and a gear ring meshing with the first gear is welded and connected to the inner wall of the separation cylinder;

[0023] Sprockets are fixed by pins on the first rotating rod outside the separation cylinder and the second rotating rod outside the inner treatment cylinder and the outer treatment cylinder. The sprockets on the first rotating rod and the second rotating rod are covered with matching chains.

[0024] Through the above technical solution, since the first side plate will not rotate with the separation cylinder, when the separation cylinder rotates axially, the ring gear will drive the gear to rotate, and the gear will drive the first rotating rod to rotate axially. Under the transmission action of the sprocket and the chain, the two second rotating rods will also rotate with the first rotating rod. Therefore, the rotation of the first rotating rod and the second rotating rod does not need to be driven by power equipment, which can reduce the overall energy consumption of the equipment.

[0025] As described above, in an efficient and low-energy industrial waste gas purification device, arc-shaped baffles are arranged on both sides of the first rotating rod, and connecting blocks are welded to one end of the two baffles close to the first side plate, and the connecting blocks are welded to the first side plate through a fixing rod.

[0026] Through the above technical solution, the arc-shaped baffle can be kept in a fixed state in the separation cylinder through the connecting block and the fixing rod, avoiding shaking and displacement, and ensuring that the rotation of the first rotating rod is not interfered with.

[0027] In the above-mentioned high-efficiency and low-energy consumption industrial waste gas purification device, the first gas outlet strip is located in the separation cylinder, and the separation cylinder is also provided with a second gas outlet strip, and one end of the first gas outlet strip and the second gas outlet strip are both fixed to the first side plate by welding with metal parts;

[0028] The first air outlet strip and the second air outlet strip are both long and flat, and one side of both of them is provided with a long air outlet slot.

[0029] Through the above technical solution, the first air outlet strip and the second air outlet strip can remain in a fixed state in the separation cylinder, and then the first air outlet strip can realize stable exhaust gas spraying, ensuring the normal operation of the exhaust gas purification operation, and the structural design of the first air outlet strip and the second air outlet strip enables the exhaust gas to be sprayed in the shape of a flat air curtain, thereby increasing the contact surface between the exhaust gas and the separation cylinder, the internal treatment cylinder and the external treatment cylinder.

[0030] As described above, a high-efficiency and low-energy consumption industrial waste gas purification device has two concentrically arranged first and second rings welded and connected on the third side plate, a first fixing ring is fixedly bonded to the inner wall of one end of the inner treatment cylinder, and the first fixing ring is movably connected to the second ring bearing, and a second fixing ring is fixedly bonded to the outer wall of one end of the outer treatment cylinder, and the second fixing ring is movably connected to the first ring bearing.

[0031] Through the above technical solution, one end of the inner processing cylinder and the outer processing cylinder can be placed on the third side plate through the first fixing ring and the second fixing ring, thereby ensuring the stability of the inner processing cylinder and the outer processing cylinder. At the same time, in conjunction with the first ring and the second ring, the third side plate will not interfere with the rotation of the inner processing cylinder and the outer processing cylinder when supporting, and the structure is reasonable.

[0032] In the above-mentioned high-efficiency and low-energy consumption industrial waste gas purification device, the through hole on the end surface of the gas collecting hood is sealed and connected to the flange at the head end of the gas outlet pipe, the tail end of the gas outlet pipe passes through the second sleeve and extends into the separation cylinder, and the tail end of the gas outlet pipe is connected to the second gas outlet strip;

[0033] The shell wall opposite to the air outlet slot of the second air outlet strip is arc-shaped, and a plurality of air outlet holes are formed in the arc-shaped portion of the shell.

[0034] Through the above technical solution, the purified exhaust gas will flow to the gas collecting hood, and after being gathered by the gas collecting hood, it can be concentrated and sent into the exhaust pipe, and finally ejected through the second exhaust strip. The ejected gas will eventually be discharged to the outside through the exhaust hole.

[0035] As described above, a high-efficiency and low-energy industrial waste gas purification device, the slag collecting component includes a movable plate, one side of the movable plate is in contact with the inner wall of the separation cylinder, the movable plate is in the shape of a long strip as a whole, and a rotating shaft fixedly bonded to the movable plate passes through the movable plate, one end of the rotating shaft passes through the fixed plate and is movably connected to the fixed plate bearing, the fixed plate is welded and fixed to the inner wall of the separation cylinder, a torsion spring is sleeved on the rotating shaft between the fixed plate and the movable plate, and the two ends of the torsion spring are respectively fixed to the fixed plate and the movable plate.

[0036] Through the above technical solution, the movable plate can rotate through the rotating shaft. When the movable plate contacts the baffle as the separation cylinder rotates, the movable plate will be squeezed and rotated, so that it can move over the baffle to ensure that it will not touch the first rotating rod. When the movable plate is separated from the baffle, the movable plate will rotate and reset under the action of the torsion spring.

[0037] As described above, a high-efficiency and low-energy consumption industrial waste gas purification device, the coating assembly includes a liquid collecting box and a sponge sleeve, one end of the liquid collecting box passes through the third side plate and is welded to the third side plate, one end of the liquid collecting box is welded to a liquid guide pipe, and a through groove is opened at the top of the liquid collecting box.

[0038] The sponge sleeve is mounted on the rotating roller, the sponge sleeve protrudes from the through slot, and the two ends of the rotating roller are movably connected to the bearings of the wall of the liquid collecting box.

[0039] The liquid guiding tube is used to guide the absorbent into the liquid collecting box.

[0040] Through the above technical solution, when the inner treatment cylinder and the outer treatment cylinder rotate, since the inner walls of both are in contact with the sponge cover, under the action of friction, the sponge cover and the rotating roller as a whole will also rotate axially. When the sponge cover rotates, it can continuously absorb the absorbent in the liquid collection box and coat the absorbent on the inner walls of the inner treatment cylinder and the outer treatment cylinder.

[0041] Beneficial effects:

[0042] (1) The present invention provides an efficient and low-energy industrial waste gas purification device, which is provided with a separation cylinder. The industrial waste gas is introduced into the separation cylinder through an air inlet pipe and a first air outlet strip. When the industrial waste gas passes through the separation cylinder, solid particles in the waste gas can be separated, thereby ensuring the subsequent chemical absorption treatment effect. At the same time, a slag collection component and a collection box are provided in the separation cylinder, so that the separated solid particles can be automatically collected as the separation cylinder rotates. A first rotating rod is also provided, and the first rotating rod can drive the bristles thereon to brush the inside of the separation cylinder by rotating, thereby ensuring the overall separation effect.

[0043] The above overall structure is simple, will not interfere with the flow of exhaust gas, ensures the exhaust gas treatment capacity, and the cleaning of the separation cylinder and the collection of solid particles can be carried out synchronously with the operation of the equipment without stopping the equipment for processing, thus ensuring the operating efficiency of the equipment.

[0044] (2) The present invention provides a high-efficiency and low-energy consumption industrial waste gas purification device, which is provided with an inner treatment cylinder and an outer treatment cylinder. When the waste gas passes through the separation cylinder, it will pass through the inner treatment cylinder and the outer treatment cylinder in sequence. The inner treatment cylinder and the outer treatment cylinder will also rotate synchronously. During the rotation process, the coating component can evenly coat a layer of chemical absorbent on the inner walls of the inner treatment cylinder and the outer treatment cylinder. Then, when the waste gas passes through the inner walls of the inner treatment cylinder and the outer treatment cylinder, it can be ensured that the absorbent is fully in contact with the waste gas, which not only ensures the purification effect of the waste gas, but also reduces the use of the absorbent, which is conducive to reducing costs;

[0045] (3) The present invention is a high-efficiency, low-energy consumption industrial waste gas purification device, which is also provided with a second rotating rod and a cleaning pool.

DETAILED DESCRIPTION

[0056] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0057] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0058] like Figure 1-3 As shown, a high-efficiency and low-energy consumption industrial waste gas purification device comprises a housing 1, and a filter assembly and an absorption assembly arranged in the housing 1, wherein the filter assembly comprises a separation cylinder 5, one side of the separation cylinder 5 is open and movably connected to a first side plate 17 bearing, a first sleeve 2 is welded and connected at the center of the other side of the separation cylinder 5, a second sleeve 3 is welded and connected at the center of the first side plate 17, an air inlet pipe 4 is inserted into the first sleeve 2, one end of the air inlet pipe 4 extends into the separation cylinder 5 and is connected to a first air outlet strip 6;

[0059] When the first sleeve 2 rotates, it will drive the separation cylinder 5 to rotate, and the exhaust gas to be treated will be introduced into the air inlet pipe 4. Finally, the exhaust gas will be ejected through the first air outlet strip 6 in the form of a flat air curtain. The ejected exhaust gas can pass through the separation cylinder 5. The separation cylinder 5 can separate the particulate matter in the exhaust gas through the sieve holes thereon. Since the separation cylinder 5 rotates continuously, different parts can be switched to contact with the exhaust gas, thereby improving the separation effect.

[0060] like Figure 1 and Figure 8 As shown, the first sleeve 2 passes through the second side plate 20 and is movably connected to the bearing of the shell 1, the second sleeve 3 passes through the third side plate 21 and is welded to the shell 1, the first sleeve 2 is welded to the second side plate 20, the second sleeve 3 is movably connected to the bearing of the third side plate 21, and the second side plate 20 is fixedly bonded to the end faces of the inner treatment cylinder 18 and the outer treatment cylinder 19.

[0061] Two concentrically arranged first and second rings 32 and 33 are welded and connected on the third side plate 21; the first fixing ring is fixedly bonded to the inner wall of one end of the inner treatment cylinder 18, and the first fixing ring is movably connected to the second ring 33 with bearings; the second fixing ring is fixedly bonded to the outer wall of one end of the outer treatment cylinder 19, and the second fixing ring is movably connected to the first ring 32 with bearings.

[0062] Both ends of the inner treatment cylinder 18 and the outer treatment cylinder 19 can be supported on the second side plate 20 and the third side plate 21. The second side plate 20 can rotate with the first sleeve 2 and drive the inner treatment cylinder 18 and the outer treatment cylinder 19 to rotate synchronously.

[0063] When the inner treatment cylinder 18 and the outer treatment cylinder 19 rotate, the other ends thereof can roll and rotate on the third side plate 21 , and thus will not drive the third side plate 21 to rotate synchronously.

[0064] like Figure 1 , Figure 2 and Figure 6 As shown, the absorption assembly includes an inner treatment cylinder 18 and an outer treatment cylinder 19. The outer treatment cylinder 19 is disposed outside the inner treatment cylinder 18. A second side plate 20 and a third side plate 21 are disposed on both sides of the inner treatment cylinder 18 and the outer treatment cylinder 19, respectively. The third side plate 21 is provided with a coating assembly for applying an absorbent to the inner walls of the inner treatment cylinder 18 and the outer treatment cylinder 19.

[0065] The coating assembly includes a liquid collecting box 25 and a sponge cover 27. One end of the liquid collecting box 25 passes through the third side plate 21 and is welded to the third side plate 21. One end of the liquid collecting box 25 is welded to a liquid guide tube 24. A through groove is provided at the top of the liquid collecting box 25.

[0066] The sponge cover 27 is sleeved on the rotating roller 26, and the sponge cover 27 protrudes from the through groove. The two ends of the rotating roller 26 are movably connected to the wall bearings of the liquid collecting box 25.

[0067] The liquid guide tube 24 is used to introduce the absorbent into the liquid collection box 25. The absorbent can be selected from sodium sulfite solution, aluminum sulfate solution, calcium hydroxide slurry, etc. It can be selected according to actual needs.

[0068] When the inner treatment cylinder 18 and the outer treatment cylinder 19 are rotating, the coating assembly can evenly coat a layer of absorbent on the inner walls of the inner treatment cylinder 18 and the outer treatment cylinder 19. When the exhaust gas passes through the inner treatment cylinder 18 and the outer treatment cylinder 19 in sequence, it can evenly contact with the absorbent, so that the absorbent can absorb harmful substances in the exhaust gas, thereby achieving the purpose of exhaust gas purification.

[0069] A medicine box is provided at the bottom of the shell 1 for loading the absorbent, and the top of the liquid guide tube 24 is connected to the bottom of the medicine box, and then under the action of gravity, the absorbent will flow into the liquid collecting box 25 through the liquid guide tube 24. When the absorbent inside the liquid collecting box 25 reaches a certain liquid level, the sponge cover 27 will absorb the absorbent, and then the sponge cover 27 can continuously rotate to continuously coat the absorbent on the inner walls of the inner treatment cylinder 18 and the outer treatment cylinder 19.

[0070] like Figure 1 , Figure 2 and Figure 5 As shown, a plurality of slag collecting components distributed in a ring shape are arranged on the inner wall of the separation cylinder 5, and the slag collecting components include a movable plate 9, one side of the movable plate 9 is in contact with the inner wall of the separation cylinder 5, the movable plate 9 is in a long strip shape as a whole, and a rotating shaft 10 fixedly bonded to the movable plate 9 is passed through the movable plate 9, one end of the rotating shaft 10 passes through the fixed plate 8 and is movably connected to the bearing of the fixed plate 8, the fixed plate 8 is welded and fixed to the inner wall of the separation cylinder 5, and a torsion spring 11 is sleeved on the rotating shaft 10 between the fixed plate 8 and the movable plate 9, and two ends of the torsion spring 11 are respectively fixed to the fixed plate 8 and the movable plate 9, and a collecting box 23 welded and connected to the first side plate 17 is passed through.

[0071] There are multiple movable plates 9, and two connected movable plates 9 and the outer circular wall of the separation cylinder 5 are enclosed to form a collection tank. When the exhaust gas passes through the separation cylinder 5, the separated particles will fall into the separation cylinder 5. As the separation cylinder 5 rotates, these particles will be concentrated in the above-mentioned collection tank. When the collection tank rotates to the top of the collection box 23, and the top of the collection box 23 is open, the particles can slide along the movable plate 9 into the collection box 23.

[0072] One end of the collecting box 23 is located outside the separation cylinder 5, and the bottom end of the collecting box 23 is in a sloped shape, so that the collected particles will slide down to one end of the collecting box 23 for centralized processing.

[0073] like Figure 1 and Figure 2 As shown, the first side plate 17 is penetrated by a first rotating rod 13 connected to its bearing, and nylon bristles are evenly distributed on the first rotating rod 13, and the nylon bristles on the first rotating rod 13 are in contact with the inner wall of the separation cylinder 5;

[0074] The third side plate 21 is penetrated by two second rotating rods 28 movably connected to the bearings thereof. Nylon bristles are evenly distributed on the second rotating rods 28 . The nylon bristles on the two second rotating rods 28 are in contact with the inner walls of the inner treatment cylinder 18 and the outer treatment cylinder 19 , respectively.

[0075] A gear is fixed to one end of the first rotating rod 13 by a bayonet, and a gear ring 12 meshing with the first gear is welded to the inner wall of the separation cylinder 5;

[0076] Sprockets are fixed by pins on the first rotating rod 13 located outside the separation cylinder 5 and the second rotating rod 28 located outside the inner treatment cylinder 18 and the outer treatment cylinder 19. The sprockets on the first rotating rod 13 and the second rotating rod 28 are covered with matching chains.

[0077] When the separation cylinder 5 rotates, the first side plate 17 will not rotate therewith. When the inner treatment cylinder 18 and the outer treatment cylinder 19 rotate, the third side plate 21 will not rotate therewith. In addition, under the transmission action of the gear ring 12 and the gear, the first rotating rod 13 will rotate by itself, thereby driving the nylon bristles to continuously scrape the inner wall of the separation cylinder 5 to prevent the separation cylinder 5 from being blocked.

[0078] Under the transmission action of the sprocket and the connection, the two second rotating rods 28 will also rotate synchronously. The second rotating rods 28 can scrape the inner treatment cylinder 18 and the outer treatment cylinder 19 through the designed bristles. Since part of the wall of the inner treatment cylinder 18 and the outer treatment cylinder 19 are located in the cleaning tank 22, the cleaning tank 22 is arranged at the bottom of the shell 1. When clean water is injected into the cleaning tank 22, the inner walls of the inner treatment cylinder 18 and the outer treatment cylinder 19 can be cleaned by scraping with the bristles to ensure the subsequent absorbent coating effect.

[0079] like Figure 2 and Figure 7 As shown, one side of the shell 1 is open and welded with a gas collecting hood 29, a through hole is provided on the end face of the gas collecting hood 29, the through hole on the end face of the gas collecting hood 29 is sealed and connected with the flange at the head end of the gas outlet pipe 30, the tail end of the gas outlet pipe 30 passes through the second sleeve 3 and extends into the separation cylinder 5, the tail end of the gas outlet pipe 30 is connected with the second gas outlet strip 7, the wall of the shell 1 opposite to the gas outlet slot of the second gas outlet strip 7 is arc-shaped, and a plurality of gas outlet holes 31 are provided on the arc-shaped part of the shell 1,

[0080] The first air outlet strip 6 is located in the separation cylinder 5, and the second air outlet strip 7 is also provided in the separation cylinder 5. One end of the first air outlet strip 6 and the second air outlet strip 7 are both fixed to the first side plate 17 by welding of metal parts. The first air outlet strip 6 and the second air outlet strip 7 are both long and flat, and a long air outlet slot is opened on one side of both.

[0081] The purified exhaust gas will flow toward the side of the gas collecting hood 29, and will flow to the exhaust pipe 30 under the gathering of the gas collecting hood 29, and finally flow into the second exhaust strip 7 and be ejected. The ejected airflow will pass through the separation cylinder 5, the inner treatment cylinder 18 and the outer treatment cylinder 19. When passing through the inner treatment cylinder 18 and the outer treatment cylinder 19, the water stains remaining on the inner walls of the inner treatment cylinder 18 and the outer treatment cylinder 19 can be blown dry to ensure the subsequent absorbent coating effect.

[0082] After passing through the inner treatment cylinder 18 and the outer treatment cylinder 19, the airflow will flow to the arc-shaped corner of the housing 1, and finally be discharged through the air outlet 31. By reusing the purified waste gas, the overall practicality of the equipment can be further improved.

[0083] The second air outlet strip 7 is located above the collecting box 23 . This design ensures that the particles can slide into the collecting box 23 .

[0084] like Figure 1 and Figure 2 As shown, the inner diameters of the separation cylinder 5, the inner treatment cylinder 18 and the outer treatment cylinder 19 gradually increase as they move inwards, and the three are coaxial.

[0085] The outer circular wall of the separation cylinder 5 is in the shape of a screen, and the outer circular walls of the inner treatment cylinder 18 and the outer treatment cylinder 19 are in a porous shape. The holes on the inner treatment cylinder 18 and the outer treatment cylinder 19 are distributed in a staggered manner.

[0086] The holes of the inner treatment tube 18 and the outer treatment tube 19 are staggered so that after the exhaust gas passes through the inner treatment tube 18 and contacts the outer treatment tube 19, the exhaust gas will not pass through directly. Instead, the exhaust gas will turn and pass through the outer treatment tube 19, thereby increasing the contact area between the exhaust gas and the outer treatment tube 19, thereby improving the purification effect of the absorbent on the exhaust gas.

[0087] The inner walls of the inner treatment cylinder 18 and the outer treatment cylinder 19 may be coated with the same type of absorbent or different types of absorbents, which may be switched according to the type of exhaust gas.

[0088] like Figure 2 and Figure 4 As shown, arc-shaped baffles 14 are arranged on both sides of the first rotating rod 13 , and connecting blocks 15 are welded to one end of the two baffles 14 close to the first side plate 17 , and the connecting blocks 15 are welded to the first side plate 17 through fixing rods 16 .

[0089] The two arc-shaped baffles 14 wrap the first rotating rod 13 to prevent the movable plate 9 from directly contacting the first rotating rod 13 , thereby ensuring that the rotation of the first rotating rod 13 is not disturbed.
