Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, and in particular to a microbial waste gas treatment system for environmental protection. Background Technology

[0002] Microbial waste gas treatment is a technology that utilizes the metabolic activity of microorganisms to oxidize and decompose harmful substances in waste gas, thereby purifying the gas. It is suitable for treating low to medium concentrations of organic waste gas, as well as waste gas containing odorous substances. Microbial treatment technology has been widely used in the treatment of VOCs waste gas generated in industries such as chemical engineering, printing, and organic synthesis.

[0003] Existing technologies, such as a microbial fermentation waste gas treatment device (authorization announcement number CN117339378B), can adjust the flow rate of the fermentation waste gas accordingly to prevent insufficient neutralization and substandard results when the flow rate is too high or too fast, thus avoiding significant impacts. This invention uses opposing nozzle assemblies to spray the neutralization solution, achieving uniform spraying. Furthermore, each nozzle assembly features a double-pipe opposing structure, further improving the uniformity of the neutralization solution spraying.

[0004] Currently, there is a lack of a treatment system that can facilitate the initial filtration of waste gas to remove larger particulate matter, then allow the waste gas to come into contact with water and a microbial biofilm to decompose the organic matter in the waste gas, and finally extract the waste gas into a second treatment tank containing an aerobic bacterial active mud layer for further treatment, thus facilitating waste gas treatment.

[0005] Therefore, in order to address the above problems, a microbial waste gas treatment system for environmental protection is proposed to solve these problems. Summary of the Invention

[0006] This invention addresses the shortcomings of existing technologies by developing a microbial waste gas treatment system for environmental protection. This invention facilitates the initial filtration of waste gas, removing larger particulate matter. The waste gas is then brought into contact with water, allowing it to contact a microbial membrane plate for decomposition of organic matter. Finally, the waste gas is extracted and further treated in a second treatment chamber containing an aerobic bacterial active sludge layer, thus facilitating waste gas treatment.

[0007] The technical solution to the problem solved by this invention is as follows: This invention provides a microbial waste gas treatment system for environmental protection, comprising: a first treatment box assembly and a filter box assembly; the filter box assembly includes a filter box, which is fixedly connected to a main air inlet pipe; the first treatment box assembly includes a first treatment box, which is connected to the filter box, and the first treatment box is connected to a conical hood via a set of supporting vertical rods, the conical hood being fixedly connected to an L-shaped gas pipe, the L-shaped gas pipe passing through the first treatment box and the filter box in a sealed manner; the first treatment box is connected to a first piston cylinder and a second piston cylinder, the first piston cylinder containing a first piston whose piston rod passes through the first piston cylinder, and the second piston cylinder containing a second piston whose piston rod passes through the second piston cylinder; the first piston cylinder is fixedly connected to a first extraction pipe, and the second piston cylinder is fixedly connected to a second extraction pipe and a first supply pipe, the first extraction pipe, the second extraction pipe, and the first supply pipe respectively passing through the first treatment box in a sealed manner. By using the filter box assembly, the waste gas is initially filtered to remove larger particulate matter, and then the microorganisms in the first treatment box assembly treat the organic matter contained in the waste gas, thereby achieving the treatment of the waste gas.

[0008] As an optimization, a main power assembly is also included. This main power assembly comprises symmetrical hydraulic rods, each connected to the first treatment chamber. The push rods of the symmetrical hydraulic rods are each connected to an L-mount plate. The piston rods of the first piston and the second piston are also connected to the L-mount plate. By employing hydraulic rods, the movement of the L-mount plate is achieved, providing power for the first treatment chamber assembly to treat the exhaust gas.

[0009] As an optimization, a processing component is also included. This component comprises a main shaft connected to a set of arc-shaped mounting frames. Each arc-shaped mounting frame houses a microbial biofilm plate. The first extraction pipe and the first delivery pipe are fixedly connected to a hollow cylinder. The main shaft bearing connects to the hollow cylinder. The arc-shaped mounting frames are matched to the hollow cylinder. The hollow cylinder and the conical cover are fixedly connected to a hollow square tube. The microbial biofilm plates treat waste gas. When toxic and odorous waste gas containing industrial waste gas, VOCs, etc., is introduced into the equipment, DM microorganisms use the pollutants in the waste gas as nutrients to grow and reproduce. Simultaneously, they biologically absorb, decompose, and deodorize the harmful substances in the waste gas, ultimately degrading them into non-toxic and odorless gases (such as carbon dioxide and water) before discharge. Rubber is used at the edges of the arc-shaped mounting frames to achieve a seal with the hollow cylinder, ensuring that the waste gas, after entering through the first delivery pipe, contacts multiple microbial biofilm plates and is extracted from the first extraction pipe, increasing the contact area between the waste gas and the microbial biofilm plates for better treatment results.

[0010] As an optimization, the L-mount plate is connected to a vertical rod, which passes through the first treatment box. The vertical rod is connected to a frame, which is connected to a bending bracket. The bending bracket is connected to a rack, and the first treatment box is connected to an L-fixed frame. The L-fixed frame is connected to the central shaft of a vertical gear via a bearing. The rack meshes with the vertical gear. The hollow cylinder bearing is connected to the central shaft of a pinion. The central shafts of the vertical gear and the pinion are respectively connected to the synchronous pulleys of the first synchronous belt mechanism. The pinion meshes with a large gear, and the large gear is connected to the main shaft via a one-way bearing. By employing the gear and rack meshing of the first synchronous belt mechanism, gear meshing, and one-way bearings, when the hydraulic rod retracts, the large gear drives the main shaft to rotate; when the hydraulic rod extends, the large gear cannot drive the main shaft to rotate. The main shaft drives the arc-shaped mounting frame and the microbial film plate to rotate intermittently, allowing the microbial film plate to contact the waste gas and achieve the decomposition of organic matter.

[0011] As an optimization, the bending bracket bearing is connected to the central shaft of the synchronous pulley of the second synchronous belt mechanism; the vertical gear is connected to the vertical rotating wheel; a vertical circular block is connected to the eccentric part of the vertical rotating wheel; the upper synchronous pulley of the second synchronous belt mechanism is connected to the L-shaped swing arm; the L-shaped swing arm is provided with a vertical groove; the vertical circular block is disposed in the vertical groove; the bending bracket is connected to a hollow ring; the hollow ring is connected to symmetrical guide rods; the symmetrical guide rods pass through the slide grooves respectively; the central shaft of the lower synchronous pulley of the second synchronous belt mechanism is connected to a turntable; the eccentric part of the turntable is connected to a power arm; the power arm is disposed in the slide groove; the slide groove bearing is connected to a guide shaft; the guide shaft passes through a circular rotating ring; the circular rotating ring bearing is connected to the hollow ring; the circular rotating ring is connected to a set of T-shafts; the guide shaft is connected to a slot plate; each T-shaft is rotatably connected to one end of a U-shaped rod; each U-shaped rod is rotatably connected to an inner connecting rod; and each inner connecting rod is rotatably connected to the slot plate. By employing a second synchronous belt mechanism, the vertical circular block is placed in the vertical groove. The lower the position of the U-shaped rod, the higher the vertical circular block is relative to the top of the vertical groove. When the vertical circular block swings, the swing angle of the L-shaped swing arm is large, and the rotation angle of the turntable is large, so that the swing amplitude of the U-shaped rod is large and matches the shape of the conical shroud. The exhaust gas enters the conical shroud in a converging shape, so that the U-shaped rod can effectively agitate the exhaust gas and water, disperse the exhaust gas, and spray it out from the conical shroud.

[0012] As an optimization, the L-shaped fixing frame is fixedly connected to the motor via a motor bracket. The output shaft of the motor passes through the L-shaped fixing frame and is connected to a square tube. The hollow ring bearing is connected to the central shaft of the transmission gear. The transmission gear is connected to a square shaft, which is housed within the square tube. The transmission gear meshes with a power gear. The guide shaft passes through the power gear, which is connected to the circular rotating ring. By placing the square shaft within the square tube and employing gear meshing transmission, the U-shaped rod swings and rotates simultaneously, driving water movement. An appropriate amount of water is added to the first treatment tank, allowing some of the moving water to enter the hollow cylinder through the hollow square tube, wetting the microbial membrane plate and facilitating its treatment of waste gas.

[0013] As an optimization, a second treatment box assembly is also included. The second treatment box assembly includes a second treatment box, inside which a main pipe and a set of branch pipes are connected. Each of the branch pipes is fixedly connected to the main pipe, and each of the branch pipes has a set of air outlets. The main pipe is fixedly connected to an L-type air transmission pipe, which passes through the second treatment box in a sealed manner and is fixedly connected to the first piston cylinder. The second treatment box is fixedly connected to the main exhaust pipe, and the first treatment box is connected to the second treatment box. A one-way valve is installed in the L-type air transmission pipe to prevent waste gas from flowing back into the first piston cylinder. An active sludge layer containing aerobic bacteria is placed inside the second treatment box, with the branch pipes positioned on the surface of the active sludge layer. Waste gas flows from the first piston cylinder through the L-type air transmission pipe, the main pipe, and the branch pipes, and is ejected from the air outlets. When residual organic matter in the waste gas dissolves in water, it is decomposed by the active sludge layer containing aerobic bacteria.

[0014] As an optimization, a set of staggered folding plates are fixedly connected inside the filter box. Each folding plate is connected to a horizontal mounting frame, and a filter plate is installed in each horizontal mounting frame. The set of folding plates and the filter box form a set of vertically spaced passageways. Exhaust gas is input into the filter box from the main inlet pipe. The exhaust gas moves gradually through the passageways, repeatedly folding back and forth to contact the filter plates, achieving the filtration of large particles. The exhaust gas then enters the conical hood through the L-shaped air pipe.

[0015] The effects described in the invention are merely those of the embodiments, and not all the effects of the invention. The above technical solutions have the following advantages or beneficial effects:

[0016] 1. This device uses a first piston cylinder and a second piston cylinder to intermittently supply and extract air into the hollow cylinder, allowing the waste gas to come into contact with the microbial membrane plates. As the waste gas flows, it contacts multiple microbial membrane plates, increasing the contact area. Moreover, since a single hydraulic rod is used, the microbial membrane plates rotate intermittently during air extraction and exhaust, allowing the microbial membrane plates to circulate and treat the waste gas, preventing a single microbial membrane plate from remaining in the same position for a long time, which would affect the waste gas treatment effect.

[0017] 2. This device uses vertical circular blocks positioned within a vertical groove. The lower the U-shaped rod, the higher the vertical circular blocks are positioned relative to the groove. When the vertical circular blocks swing, the L-shaped swing arm swings at a large angle, resulting in a large rotation angle of the turntable and a large swing amplitude of the U-shaped rod. This large amplitude matches the shape of the conical hood, causing the exhaust gas to converge upon entering the hood. This allows the U-shaped rod to effectively agitate the exhaust gas and water, dispersing the exhaust gas before it is ejected from the hood. Furthermore, the simultaneous swing and rotation of the U-shaped rod drives the water movement, allowing some of the water to flow through the hollow square tube into the hollow cylinder, wetting the microbial membrane plate and facilitating its treatment of the exhaust gas.

[0037] like Figures 1 to 11As shown in Embodiment 1: An environmental protection microbial waste gas treatment system includes: a first treatment box assembly 1 and a filter box assembly 4; the filter box assembly 4 includes a filter box 41, which is fixedly connected to a main air inlet pipe 46; the first treatment box assembly 1 includes a first treatment box 15, which is connected to the filter box 41, and the first treatment box 15 is connected to a conical hood 17 via a set of supporting vertical rods 18, the conical hood 17 is fixedly connected to an L-shaped air pipe 16, and the L-shaped air pipe 16 passes through the first treatment box 15 and the filter box 41 in a sealed manner; the first treatment box 15 is connected to the first... The system comprises a piston cylinder 11 and a second piston cylinder 13. A first piston 12 is housed within the first piston cylinder 11, with its piston rod passing through the first piston cylinder 11. A second piston 14 is housed within the second piston cylinder 13, with its piston rod passing through the second piston cylinder 13. The first piston cylinder 11 is fixedly connected to a first extraction pipe 113, and the second piston cylinder 13 is fixedly connected to a second extraction pipe 111 and a first delivery pipe 112. The first extraction pipe 113, the second extraction pipe 111, and the first delivery pipe 112 are respectively sealed through the first treatment chamber 15. Preliminary filtration of the exhaust gas is achieved using the filter assembly 4, filtering out larger particulate matter. Then, the microorganisms in the first treatment chamber assembly 1 treat the organic matter contained in the exhaust gas, thus achieving exhaust gas treatment.

[0038] One-way valves are installed in the first suction pipe 113, the second suction pipe 111, and the first air delivery pipe 112, respectively, so that air is drawn from the suction pipe into the piston cylinder and discharged through the first air delivery pipe 112.

[0039] It also includes a main power assembly 2, which comprises symmetrical hydraulic rods 21. The symmetrical hydraulic rods 21 are respectively connected to the first treatment box 15, and the push rods of the symmetrical hydraulic rods 21 are respectively connected to the L-mounting plate 22. The piston rods of the first piston 12 and the second piston 14 are respectively connected to the L-mounting plate 22. By using the hydraulic rods 21, the movement of the L-mounting plate 22 is achieved, providing power for the first treatment box assembly 1 to treat the exhaust gas.

[0040] The system also includes a second treatment box assembly 3, which comprises a second treatment box 33. The second treatment box 33 is connected to a main pipe 36 and a set of branch pipes 34. Each set of branch pipes 34 is fixedly connected to the main pipe 36 and has a set of air outlets 35. The main pipe 36 is fixedly connected to an L-type air transmission pipe 31, which passes through the second treatment box 33 in a sealed manner. The L-type air transmission pipe 31 is fixedly connected to the first piston cylinder 11. The second treatment box 33 is fixedly connected to a main exhaust pipe 32. The first treatment box 15 is connected to the second treatment box 33. A one-way valve is installed in the L-type air transmission pipe 31 to prevent waste gas from flowing back into the first piston cylinder 11. An active sludge layer containing aerobic bacteria is placed inside the second treatment box 33, with the branch pipes 34 positioned on the surface of the active sludge layer. The exhaust gas is ejected from the first piston cylinder 11 through the L-type air transmission pipe 31, the main pipe 36 and the branch pipe 34, and then ejected from the air outlet 35. When the residual organic matter in the exhaust gas dissolves in water, it is decomposed by the aerobic bacteria active mud layer.

[0041] A set of staggered folding plates 42 are fixedly connected inside the filter box 41. Each folding plate 42 is connected to a horizontal mounting frame 45, and a filter plate 43 is installed in each horizontal mounting frame 45. The set of folding plates 42 and the filter box 41 form a set of vertically spaced passageways 44. Exhaust gas is input into the filter box 41 from the main air inlet pipe 46. The exhaust gas moves gradually through the passageways 44, and after multiple folding movements, it contacts the filter plates 43, achieving the filtration of large particles. The exhaust gas then enters the conical hood 17 through the L-shaped air pipe 16.

[0042] The workflow of this embodiment is as follows:

[0043] The second treatment box 33 contains an active mud layer containing aerobic bacteria, so that the branch pipe 34 is located on the surface of the active mud layer.

[0044] Pour an appropriate amount of water into the first treatment tank 15.

[0045] The exhaust gas is fed into the filter box 41 through the main intake pipe 46. The exhaust gas moves gradually through the groove 44 and makes multiple back-and-forth movements to contact the filter plate 43, thereby filtering large particles. The exhaust gas is then discharged through the L-pipe 16 into the conical hood 17.

[0046] The hydraulic rod 21 reciprocates, causing the L-mounting plate 22 to move back and forth. The L-mounting plate 22, in turn, causes the first piston 12 and the second piston 14 to move back and forth. The first extraction pipe 113 draws gas into the first piston cylinder 11, and then discharges it from the L-transmission pipe 31. The second extraction pipe 111 draws gas into the second piston cylinder 13, and then discharges it from the first delivery pipe 112. Gas from the L-transmission pipe 31 enters the main pipe 36 and branch pipes 34, and is discharged from the outlet 35. The aerobic bacteria-containing active mud layer decomposes organic matter dissolved in the water, and the waste gas is discharged from the main exhaust pipe 32. A gas collection system can be connected via pipeline for further treatment.

[0047] Example 2: This example further elaborates on Example 1 and includes a processing component 5. The processing component 5 includes a main shaft 58, which is connected to a set of arc-shaped mounting frames 56. Each arc-shaped mounting frame 56 houses a microbial biofilm plate 57. The first exhaust pipe 113 and the first exhaust pipe 112 are fixedly connected to a hollow cylinder 110. The main shaft 58 is bearing-connected to the hollow cylinder 110. The arc-shaped mounting frames 56 are matched to the hollow cylinder 110. The hollow cylinder 110 and the conical cover 17 are fixedly connected to a hollow square tube 19. The microbial biofilm plate 57 treats waste gas. When industrial waste gas, VOCs, and other toxic and odorous waste gas are introduced into the equipment, DM microorganisms will use the pollutants in the waste gas as nutrients to grow and reproduce. At the same time, they will biologically absorb, decompose, and deodorize the harmful substances in the waste gas, ultimately degrading them into non-toxic and odorless gases (such as carbon dioxide and water) before discharge. The edge of the arc-shaped mounting frame 56 is sealed with rubber to the hollow cylinder 110, so that the exhaust gas enters through the first air supply pipe 112 and comes into contact with multiple microbial membrane plates 57, and is then extracted from the first air extraction pipe 113, increasing the contact area between the exhaust gas and the microbial membrane plates 57 and resulting in better treatment effect.

[0048] Common microorganisms include bacteria such as *Pseudomonas* and *Bacillus*, as well as fungi such as white-rot fungi and *Trichoderma*. In practical applications, it is necessary to select appropriate microbial populations and growth conditions based on the specific composition and conditions of the waste gas to form an effective biofilm.

[0049] The L-mount plate 22 is connected to a vertical rod 23, which passes through the first processing box 15. The vertical rod 23 is connected to a frame 24, which is connected to a bending bracket 59. The bending bracket 59 is connected to a rack 510. The first processing box 15 is connected to an L-fixed frame 114. The L-fixed frame 114 is connected to the central shaft of the vertical gear 514 by a bearing. The rack 510 meshes with the vertical gear 514. The hollow cylinder 110 is connected to the central shaft of the pinion 53 by a bearing. The central shafts of the vertical gear 514 and the pinion 53 are respectively connected to the synchronous pulleys of the first synchronous belt mechanism 54. The pinion 53 meshes with a large gear 52. The large gear 52 is connected to the main shaft 58 through a one-way bearing. By employing the first synchronous belt mechanism 54 with gear and rack meshing, gear meshing, and one-way bearings, when the hydraulic rod 21 retracts, the large gear 52 drives the main shaft 58 to rotate; when the hydraulic rod 21 extends, the large gear 52 cannot drive the main shaft 58 to rotate. The main shaft 58 drives the arc-shaped mounting frame 56 and the microbial film plate 57 to rotate intermittently, so that the microbial film plate 57 comes into contact with the waste gas, thereby decomposing organic matter.

[0050] A one-way bearing, also known as a stop-return bearing, clutch bearing, or overrunning clutch, is a special type of bearing. Its main characteristic is that it can rotate freely in one direction while being locked in the other, thus achieving unidirectional transmission.

[0051] The workflow of this embodiment is as follows:

[0052] When the hydraulic rod 21 reciprocates, the L-mounting plate 22 drives the vertical rod 23, frame 24, bending bracket 59 and rack 510 to reciprocate. The rack 510 drives the vertical gear 514 to rotate. The vertical gear 514 drives the pinion 53 to rotate through the first synchronous belt mechanism 54. The pinion 53 drives the large gear 52 to move. When the hydraulic rod 21 retracts, the large gear 52 drives the main shaft 58 to rotate. When the hydraulic rod 21 extends, the large gear 52 cannot drive the main shaft 58 to rotate. The main shaft 58 drives the arc-shaped mounting frame 56 and the microbial film plate 57 to rotate intermittently, so that the microbial film plate 57 comes into contact with the exhaust gas and decomposes the organic matter.

[0053] Example 3: This example further elaborates on Example 2. The bending bracket 59 is connected to the central shaft of the synchronous pulley of the second synchronous belt mechanism 515 via a bearing. The vertical gear 514 is connected to the vertical rotating wheel 513. A vertical circular block 520 is connected to the eccentric part of the vertical rotating wheel 513. The upper synchronous pulley of the second synchronous belt mechanism 515 is connected to the L-shaped swing arm 511. The L-shaped swing arm 511 is provided with a vertical groove 512. The vertical circular block 520 is disposed in the vertical groove 512. The bending bracket 59 is connected to a hollow ring 530. The hollow ring 530 is connected to symmetrical guide rods 517. The symmetrical guide rods 517 pass through the sliding grooves 523 respectively. The second synchronous belt mechanism 515... The central shaft of the lower synchronous pulley of the stepping belt mechanism 515 is connected to the turntable 521. The eccentric part of the turntable 521 is connected to the power arm 522. The power arm 522 is set in the slide groove 523. The slide groove 523 is connected to the guide shaft 524 by a bearing. The guide shaft 524 passes through the circular rotating ring 525. The circular rotating ring 525 is connected to the hollow ring 530 by a bearing. The circular rotating ring 525 is connected to a set of T-shafts 526. The guide shaft 524 is connected to the groove plate 527. Each T-shaft 526 is rotatably connected to one end of a U-shaped rod 529. Each U-shaped rod 529 is rotatably connected to an inner connecting rod 528. Each inner connecting rod 528 is rotatably connected to the groove plate 527. By employing the second synchronous belt mechanism 515, the vertical circular block 520 is set inside the vertical groove 512. When the position of the U-shaped rod 529 is lower, the vertical circular block 520 is relatively positioned at the upper part of the vertical groove 512. When the vertical circular block 520 swings, the swing angle of the L-shaped swing arm 511 is large, and the rotation angle of the turntable 521 is large, so that the swing amplitude of the U-shaped rod 529 is large, which matches the shape of the conical shroud 17. The exhaust gas enters the conical shroud 17 in a converging shape, so that the U-shaped rod 529 can effectively agitate the exhaust gas and water, disperse the exhaust gas, and spray it out from the conical shroud 17.

[0054] The workflow of this embodiment is as follows:

[0055] When the hydraulic rod 21 reciprocates, the bending bracket 59 drives the hollow ring 530, guide rod 517, slide groove 523, second synchronous belt mechanism 515, L-shaped swing arm 511, turntable 521, power arm 522, guide shaft 524, circular rotating ring 525, T-shaft 526, groove plate 527, inner connecting rod 528, and U-shaped rod 529 to move. The vertical gear 514 drives the vertical rotating wheel 513 to rotate, and the vertical rotating wheel 513 drives the vertical circular block 520 to swing along the vertical groove 512. The vertical circular block 520 drives the L-shaped swing arm 511 to swing back and forth. The L-shaped swing arm 511 drives the turntable 521 to rotate back and forth through the second synchronous belt mechanism 515. The turntable 521 drives the power arm 522 to swing within the slide groove 523. The power arm 522 drives the slide groove 523 to move along the guide rod 517. The slide groove 523 drives the guide shaft 524 and the groove plate 527 to move. The groove plate 527 drives the inner connecting rod 528 to swing. The inner connecting rod 528 drives the U-shaped rod 529 to swing back and forth.

[0056] Example 4: This example further elaborates on Example 3. The L-shaped fixing frame 114 is fixedly connected to the motor 51 via a motor bracket. The output shaft of the motor 51 passes through the L-shaped fixing frame 114 and is connected to the square tube 55. The hollow ring 530 is connected to the central shaft of the transmission gear 518 via a bearing. The transmission gear 518 is connected to the square shaft 519, which is located inside the square tube 55. The transmission gear 518 meshes with the power gear 516. The guide shaft 524 passes through the power gear 516, which is connected to the circular rotating ring 525. By placing the square shaft 519 inside the square tube 55 and using gear meshing transmission, the U-shaped rod 529 swings and rotates simultaneously, driving water movement. An appropriate amount of water is added to the first treatment tank 15, allowing some of the moving water to enter the hollow cylinder 110 through the hollow square tube 19, wetting the microbial membrane plate 57 and facilitating its treatment of waste gas.

[0057] The workflow of this embodiment is as follows:

[0058] When the hydraulic rod 21 reciprocates, the hollow ring 530 drives the transmission gear 518 to move, the circular rotating ring 525 drives the power gear 516 to move, the transmission gear 518 drives the square shaft 519 to move along the square tube 55, and controls the motor 51 to rotate. The motor 51 drives the square tube 55, the square shaft 519 and the transmission gear 518 to rotate. The transmission gear 518 drives the power gear 516, the guide shaft 524, the circular rotating ring 525 and the groove plate 527 to rotate. The circular rotating ring 525 drives the T-shaft 526 to swing, the groove plate 527 drives the inner connecting rod 528 to swing, and the inner connecting rod 528 and the T-shaft 526 drive the U-shaped rod 529 to swing.

[0059] This device uses a first piston cylinder 11 and a second piston cylinder 13 to intermittently supply and extract air into the hollow cylinder 110, allowing the waste gas to come into contact with the microbial membrane plates 57. As the waste gas flows, it contacts multiple microbial membrane plates 57, increasing the contact area. Furthermore, since the same hydraulic rod 21 is used, the microbial membrane plates 57 rotate intermittently while the air is being extracted and exhausted, allowing the microbial membrane plates 57 to circulate and treat the waste gas. This prevents a single microbial membrane plate 57 from remaining in the same position for a long time, which would affect the waste gas treatment effect.

[0060] This device arranges a vertical circular block 520 within a vertical groove 512. When the U-shaped rod 529 is positioned low, the vertical circular block 520 is relatively positioned above the vertical groove 512. When the vertical circular block 520 swings, the swing angle of the L-shaped swing arm 511 and the rotation angle of the turntable 521 are both large, resulting in a large swing amplitude of the U-shaped rod 529. This matches the shape of the conical shroud 17, causing the exhaust gas to converge upon entering the conical shroud 17. This allows the U-shaped rod 529 to effectively agitate the exhaust gas and water, dispersing the exhaust gas before it is ejected from the conical shroud 17. Furthermore, the simultaneous swing and rotation of the U-shaped rod 529 drives the water movement, allowing some of the moving water to enter the hollow cylinder 110 through the hollow square tube 19, wetting the microbial membrane plate 57 and facilitating its treatment of the exhaust gas.

[0061] Although the specific embodiments of the invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the invention. Based on the technical solutions of the invention, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the invention.
