Description

Technical Field

[0001] The present invention belongs to the technical field of waste gas absorption devices, and specifically relates to a waste gas absorption device for a regenerative incinerator. Background Art

[0002] The problem of environmental pollution caused by tail gas emissions is an important object of supervision by local governments over enterprises. During the production process of carbon fiber, tail gas is generated, and the tail gas contains organic substances such as acrylonitrile and dimethyl sulfoxide. Direct emission will cause harm to the environment and also result in waste of resources.

[0003] The tail gas emitted by the incinerator is very likely to pollute the environment and needs to be treated before being discharged into the environment. Because it is difficult to fully burn the materials during the incineration process in the incinerator, the incinerated tail gas will contain a large amount of combustible small particles. Directly filtering the tail gas will easily clog the filter screen, so it is difficult to effectively treat the tail gas. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the technical solution adopted by the present invention to solve its technical problems is as follows: An exhaust gas absorption device for a regenerative incinerator, including a main processing box, on the surface of the main processing box is fixedly connected a control panel, and inside the main processing box are provided: An extrusion catalytic barrel, the bottom end of which is fixedly connected to the center of the bottom of the inner cavity of the main processing box. At the bottom of the inner cavity of the extrusion catalytic barrel is fixedly connected a rotating fan housing, and inside the rotating fan housing is rotatably connected a rotating shaft fan blade. At the top of the inner cavity of the extrusion catalytic barrel is fixedly connected an air outlet pipe, and slidably connected at the top of the inner cavity of the extrusion catalytic barrel is a pressurizing device, through which the gas inside the extrusion catalytic barrel can be squeezed downward; An intake rotating pipe, one end of which close to the extrusion catalytic barrel is fixedly connected to the inner cavity of the extrusion catalytic barrel. At the top end of the inner cavity of the intake rotating pipe is slidably connected a U-shaped rotating pipe through an anti-backflow device. In the middle of the inner cavity of the U-shaped rotating pipe is fixedly connected a filter, and the end of the U-shaped rotating pipe away from the intake rotating pipe is rotatably connected to an incineration device. The incineration device includes a feeding rod, at the bottom end of which is fixedly connected a flame spraying rod. On both sides of the inner cavity of the flame spraying rod are symmetrically provided spray openings. At the bottom of the surface of the feeding rod is fixedly connected an independent rotating sleeve, and on both sides of the surface of the independent rotating sleeve are rotatably connected heat insulation clamping plates. On one side of the inner cavity of the heat insulation clamping plate away from the independent rotating sleeve is rotatably connected a side cover, and in the middle of the inner cavity of the heat insulation clamping plate is fixedly connected a metal sweeping rod. At the bottom of the surface of the heat insulation clamping plate is rotatably connected a power rotating column, and inside the axis of the power rotating column is inserted a driving motor. At the axis of the inner cavity of the right heat insulation clamping plate is fixedly connected a ventilation pipe. When using this device to carry out the treatment work on the exhaust gas, the exhaust gas is introduced into the inside of this device through the ventilation pipe. First, the exhaust gas enters the inside of the incineration device. During this process, the holes on one side of the fixed disk and the holes on the other side of the misaligned rotating disk are staggered from each other. Therefore, when the ventilation pipe is closed, the feeding rod uses the method of inputting clean fuel to ignite the exhaust gas introduced into the inner cavity of the heat insulation clamping plate through the flame spraying rod to carry out the complete incineration work.

[0005] Preferably, a fixed disk is fixedly connected to one end of the inner cavity of the U-shaped rotating pipe away from the intake rotating pipe. A misaligned rotating disk is rotatably connected to one side of the fixed disk surface close to the incineration device. A through opening is formed on one side of the inner cavity of the fixed disk, and a through opening is also formed on one side of the inner cavity of the misaligned rotating disk. The through opening of the fixed disk and the through opening of the misaligned rotating disk are staggered with each other. The surface of the misaligned rotating disk is fixedly connected to the inner cavity of the left heat insulation clamping disk through a plug rod. During the incineration process, the driving motor controls the self-rotation of the heat insulation clamping disk through the friction force of the power rotating column, so that the metal sweeping rod on the inner wall of the heat insulation clamping disk continuously sweeps across the inner cavity of the heat insulation clamping disk, stirring up the waste gas residues accumulated in the inner cavity of the heat insulation clamping disk, so that the combustible substances in the waste gas can be fully burned by the flame spraying rod in a short time. During this process, because the left heat insulation clamping disk rotates continuously, the burned waste gas will be discharged into the U-shaped rotating pipe through the periodically connected fixed disk and misaligned rotating disk, and then input into the inside of the extrusion catalytic barrel. After reacting with the catalyst to consume toxic substances, it is discharged from the air outlet pipe to complete the waste gas treatment work.

[0006] Preferably, a blower is fixedly connected to one side of the bottom of the inner cavity of the main processing box away from the incineration device. A cooling plate is fixedly connected to the surface of the blower. A beam collecting pipe is fixedly connected to the through opening at the top of the inner cavity of the blower. And a catalytic cylinder shell is fixedly connected to one side of the top of the inner cavity of the beam collecting pipe close to the blower through a connecting pipe. A feeding pipe is fixedly connected to one end of the inner cavity of the catalytic cylinder shell away from the beam collecting pipe. The inner cavity of the catalytic cylinder shell is filled with VOCs gas. One end of the ventilation pipe away from the heat insulation clamping disk extends to the outside of the main processing box. One end of the air outlet pipe away from the extrusion catalytic barrel extends to the outside of the main processing box. The strip-shaped filter plate of this device can filter out a small amount of non-combustible substances in the waste gas, preventing the waste gas from colliding with the blades of the rotating fan during the subsequent compression process, thereby causing the problem of shortened blade life. And the strip-shaped filter plate of this device can, without disassembly, through the operation of external personnel, use an air extraction pump to clean the inner cavity of the strip-shaped filter plate, preventing the problem that frequent replacement of the strip-shaped filter plate easily leads to poor air tightness of the device.

[0007] Preferably, the anti-backflow device includes an inner cylinder shell. A vertical hollow rod is slidably connected to the axis of the inner cavity of the inner cylinder shell. A thrust spring is sleeved on the top surface of the vertical hollow rod. The top end of the inner cavity of the intake rotary pipe is fixedly connected with a sealed fixed shell. A sliding inner shell is slidably connected to the inner cavity of the sealed fixed shell. The bottom end of the sliding inner shell is slidably connected with a dynamometer through a traction pull rod. The left end of the U-shaped rotary pipe and the intake rotary pipe are usually in a separated state. At this time, the thrust spring pushes the vertical hollow rod downward, so that the air groove at the top of the vertical hollow rod enters the inside of the inner cylinder shell, and the inner cylinder shell is in a sealed state. When exhaust is required, the whole U-shaped rotary pipe is pressed downward through an external pressing rod, the feeding rod extends, and the surface of the driving motor slides down along the inner wall of the main processing box. When the left end of the U-shaped rotary pipe descends, the bottom end of the vertical hollow rod first inserts into the axis of the intake rotary pipe directly below. Subsequently, the vertical hollow rod rises along the inner cavity of the inner cylinder shell under the pushing action of the reaction force. The bottom end of the vertical hollow rod pushes the sliding inner shell downward. At this time, the U-shaped rotary pipe is connected to the intake rotary pipe through the vertical hollow rod, and the two dynamometers monitor the descending height of the sliding inner shell.

[0008] Preferably, a side intake groove is formed at the bottom of the inner cavity of the vertical hollow rod. Vertical cutting grooves are uniformly formed at the top of the inner cavity of the sliding inner shell. The bottom end of the vertical hollow rod is slidably connected to the top of the inner cavity of the intake rotary pipe through an axial socket. The bottom end of the vertical hollow rod is pressed against the top of the sealed fixed shell. The top end of the sliding inner shell is slidably connected to the top of the inner cavity of the sealed fixed shell through a connecting spring. The surface of the dynamometer is fixedly connected to the top of the inner cavity of the intake rotary pipe. The surface of the inner cylinder shell is fixedly connected to the bottom end of the inner cavity of the U-shaped rotary pipe. A filter plate is arranged in the middle of the inner cavity of the U-shaped rotary pipe. During the secondary combustion operation, the U-shaped rotary pipe and the intake rotary pipe are separated from each other, and both the U-shaped rotary pipe and the intake rotary pipe are in a relatively sealed state. After the gas inside the U-shaped rotary pipe burns out, it is connected to the intake rotary pipe, automatically forming a passage to realize the gas transfer work, which can effectively prevent the mixed gas from flowing back during the catalytic reaction, resulting in an increase in the consumption of the catalyst. At the same time, the dynamometer can prevent the U-shaped rotary pipe and the intake rotary pipe from being over-pressed and control the pressing effect of the external pressing rod.

[0009] Preferably, the filter plate includes an external pressure rod, a vertical connecting rod is fixedly connected to the axis center of the top of the inner cavity of the external pressure rod, the surface of the vertical connecting rod is slidably connected to an adaptive baffle, the surface of the adaptive baffle is fixedly connected to the middle of the inner cavity of the U-shaped rotating tube, the bottom end of the vertical connecting rod is fixedly connected to a spring clamp, the top of the inner cavity of the spring clamp is fixedly connected to a strip filter plate, and the side of the inner cavity of the adaptive baffle close to the incineration device is fixedly connected to an exhaust pump. Under normal circumstances, the exhaust gas after combustion enters the U-shaped rotating tube through the through-hole of the fixed disk. When passing through the middle of the U-shaped rotating tube, it passes through the strip filter plate for simple filtration. However, the middle of the inner cavity of the strip filter plate after filtration will be clogged. After a period of filtration, the exhaust gas is stopped, the external pressure rod is pressed downward, and the vertical connecting rod slides down along the inner cavity of the adapter baffle, pushing the strip filter plate downward. At this time, the side-mounted vacuum pump can reversely extract the residue in the inner cavity of the strip filter plate, and then drop it to the bottom of the inner cavity of the adapter baffle. The strip filter plate of this device can filter out a small amount of incombustible substances in the exhaust gas, preventing the exhaust gas from colliding with the blades of the rotating fan blades during the subsequent compression process, thereby shortening the life of the blades. The strip filter plate of this device can be cleaned by an external person using a vacuum pump without disassembly, preventing the frequent replacement of the strip filter plate from easily causing the airtightness of the device to deteriorate.

[0010] Preferably, the pressurizing device includes a folding cylindrical shell, the bottom end of which is fixedly connected to a sliding chassis, the top end of which is fixedly connected to the top of the inner cavity of the extruded catalytic barrel, the top of the surface of the sliding chassis is fixedly connected to a telescopic pull rod, the axis of the inner cavity of the sliding chassis is slidably connected to a piston push plate, and the bottom end of the sliding chassis is fixedly connected to a buffer plate. During the catalytic reaction, the catalytic cylindrical shell passes the VOCs gas in the inner cavity into the extruded catalytic barrel through the cluster pipe, and then the blower ventilates to prevent gas backflow. At this time, the telescopic pull rods on both sides push the sliding chassis downward, and the sliding chassis mixes and compresses the VOCs gas at the bottom with the toxic gas introduced from the right end. Subsequently, the shaft at the top end of the rotating shaft fan blade is inserted into the inner cavity of the sliding chassis. During this process, the rotating shaft fan blade continuously rotates to mix the gas, so that the toxic gas is fully purified. Subsequently, the top end of the rotating shaft fan blade pushes the piston push plate upward, and the gas enters the interior of the folding cylindrical shell and is discharged to the outside of the device through the outlet pipe to complete the purification work. When the device uses VOCs gas to remove toxic substances in exhaust gas, the exhaust gas and VOCs gas react fully through the compression of the sliding chassis and the rotation of the shaft fan blades, thereby effectively preventing the problem of insufficient reaction of toxic substances. In addition, during the catalytic reaction, VOCs gas can be added at any time without gas leakage to enhance the catalytic reaction, avoiding the problem of waste due to excessive addition of VOCs gas and insufficient reaction due to insufficient addition.

[0011] Preferably, the buffer disk includes a flat buffer disk housing. In the middle of the inner cavity of the flat buffer disk housing, a transfer ring is fixedly connected. On the surface of the transfer ring, an arc-shaped rotating cylinder is rotatably connected. On the side of the arc-shaped rotating cylinder surface away from the piston push disk, a pressing switch is slidably connected. At the bottom end of the pressing switch, a control magnetic plate is fixedly connected. The top end of the rotating shaft fan blade is slidably connected to the axis center of the inner cavity of the flat buffer disk housing. The surface of the arc-shaped rotating cylinder is rotatably connected to the top end of the rotating shaft fan blade. The top of the arc-shaped rotating cylinder is fixedly connected to the top of the inner cavity of the flat buffer disk housing through a spring band. During the continuous descent of the sliding chassis, the shaft rod at the top end of the rotating shaft fan blade first inserts into the axis center of the flat disk housing. Subsequently, the shaft rod at the top end of the rotating shaft fan blade has relative friction with the outer surfaces of the two arc-shaped rotating cylinders on both sides, thereby causing the arc-shaped rotating cylinder to rotate along the transfer ring and pressing the pressing switch below. At this time, the control magnetic plate starts to work, endowing the bottom of the sliding chassis with magnetism. Moreover, a magnet is also arranged in the inner cavity of the rotating shaft fan blade. The magnets on the upper and lower sides generate a repulsive force, making it increasingly difficult for the sliding chassis to slide downward, thereby effectively preventing the problem that the sliding chassis slides excessively downward, resulting in the fan blades of the rotating shaft fan blade touching the sliding chassis and causing damage to the fan blades.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The device can remove impurities from the tail gas discharged from the incinerator through secondary combustion, thereby consuming the impurity particles in the tail gas and making it not easy to block the filter screen inside the device during the filtering process of the tail gas, so that the device filters more smoothly. And during the process of secondary combustion of the tail gas in the inner cavity of the heat insulation chuck, the continuously rotating metal sweeping rod can disperse the waste gas residues accumulated in the inner cavity of the heat insulation chuck, thereby making the combustion efficiency of the waste gas of the device higher, and then reducing the time and energy consumption required for combustion.

[0014] [[ID=IO]]2. The strip-shaped filter plate of the device can filter out a small amount of non-combustible substances in the waste gas, preventing the waste gas from colliding with the blades of the rotating fan during the subsequent compression process, thereby avoiding the problem of shortening the blade life. And the strip-shaped filter plate of the device can, without disassembly, be cleaned by an external operator using an air pump to clean the inner cavity of the strip-shaped filter plate through external operation, preventing the problem that frequent replacement of the strip-shaped filter plate easily leads to poor airtightness of the device.

[0015] 3. During the secondary combustion operation, the U-shaped rotating pipe and the intake rotating pipe are separated from each other, and both the U-shaped rotating pipe and the intake rotating pipe are in a relatively sealed state. After the gas inside the U-shaped rotating pipe is burned out, it is connected to the intake rotating pipe, automatically forming a passage to realize the gas transfer work, which can effectively prevent the problem that the mixed gas flows back during the catalytic reaction, resulting in an increase in the consumption of the catalyst. At the same time, the tensiometer can prevent the U-shaped rotating pipe and the intake rotating pipe from being overly squeezed and control the pressing effect of the external pressing rod.

[0016] It should be noted that in the original text, "[[ID=IO]]" should probably be "", and this has been corrected in the translation.4. When the device uses VOCs gas to remove toxic substances in the waste gas, through the compression of the sliding chassis and the rotation of the rotating shaft fan blades, the waste gas and VOCs gas can react fully, thus effectively preventing the problem of insufficient reaction of toxic substances. And during the catalytic reaction process, VOCs gas can be added at any time without gas leakage to enhance the catalytic reaction, avoiding the problems of waste caused by excessive addition of VOCs gas and insufficient reaction caused by too little addition.

[0017] 5. During the continuous descent of the sliding chassis, the shaft rod at the top of the rotating shaft fan blade first inserts into the center of the flat disk shell. Subsequently, the shaft rod at the top of the rotating shaft fan blade has relative friction with the outer surfaces of the two arc-shaped rotating cylinders on both sides, causing the arc-shaped rotating cylinders to rotate along the adapter ring. Press the pressing switch below. At this time, the control magnet starts to work, endowing magnetism to the bottom of the sliding chassis. And there is also a magnet in the inner cavity of the rotating shaft fan blade. The magnets on the upper and lower sides generate repulsive force, making it increasingly difficult for the sliding chassis to slide downward, thus effectively preventing the problem that the sliding chassis slides down excessively, resulting in the fan blades of the rotating shaft fan blade touching the sliding chassis and causing damage to the fan blades.

[0028] Embodiment 1

[0029] Please refer to Figures 1-4 , the present invention provides a technical solution: an exhaust gas absorption device for a regenerative incinerator, including a main processing box 1, a control panel 12 is fixedly connected to the surface of the main processing box 1, and the following are arranged in the inner cavity of the main processing box 1:

[0030] An extrusion catalytic barrel 2, the bottom end of the extrusion catalytic barrel 2 is fixedly connected to the axis of the bottom of the inner cavity of the main processing box 1, a rotating fan shell 21 is fixedly connected to the bottom of the inner cavity of the extrusion catalytic barrel 2, a rotating shaft fan blade 22 is rotatably connected to the bottom of the inner cavity of the rotating fan shell 21, an exhaust pipe 14 is fixedly connected to the top of the inner cavity of the extrusion catalytic barrel 2, and a pressurizing device 7 is slidably connected to the top of the inner cavity of the extrusion catalytic barrel 2. Through the pressurizing device 7, the gas in the inner cavity of the extrusion catalytic barrel 2 can be extruded downward;

[0031] An intake rotary pipe 23, one end of the intake rotary pipe 23 close to the extrusion catalytic barrel 2 is fixedly connected to the inner cavity of the extrusion catalytic barrel 2. A U-shaped rotary pipe 11 is slidably connected to the top end of the inner cavity of the intake rotary pipe 23 through a backflow prevention device 6. A filter is fixedly connected to the middle of the inner cavity of the U-shaped rotary pipe 11. One end of the U-shaped rotary pipe 11 away from the intake rotary pipe 23 is rotatably connected to an incineration device 5.

[0032] The incineration device 5 includes a feeding rod 51. A spraying rod 52 is fixedly connected to the bottom end of the feeding rod 51. Spray ports 54 are symmetrically arranged on both sides of the inner cavity of the spraying rod 52. An independent rotating sleeve 53 is fixedly connected to the bottom of the surface of the feeding rod 51. Heat insulation clamping plates 55 are rotatably connected to both sides of the surface of the independent rotating sleeve 53. A side cover 56 is rotatably connected to one side of the inner cavity of the heat insulation clamping plate 55 away from the independent rotating sleeve 53. A metal sweeping rod 57 is fixedly connected to the middle of the inner cavity of the heat insulation clamping plate 55. A power rotating column 59 is rotatably connected to the bottom of the surface of the heat insulation clamping plate 55. A driving motor 58 is inserted into the axis of the inner cavity of the power rotating column 59. A ventilation pipe 13 is fixedly connected to the axis of the inner cavity of the right heat insulation clamping plate 55.

[0033] A fixed disk 510 is fixedly connected to one end of the inner cavity of the U-shaped rotary pipe 11 away from the intake rotary pipe 23. A misaligned rotary disk 511 is rotatably connected to one side of the surface of the fixed disk 510 close to the incineration device 5. A through port is arranged on one side of the inner cavity of the fixed disk 510. A through port is also arranged on one side of the inner cavity of the misaligned rotary disk 511. And the through port of the fixed disk 510 and the through port of the misaligned rotary disk 511 are staggered with each other. The surface of the misaligned rotary disk 511 is fixedly connected to the inner cavity of the left heat insulation clamping plate 55 through a plug rod.

[0034] A blower 3 is fixedly connected to one side of the bottom of the inner cavity of the main processing box 1 away from the incineration device 5. A cooling plate 31 is fixedly connected to the surface of the blower 3. A bundled ventilation pipe 42 is fixedly connected to the through port at the top of the inner cavity of the blower 3. And one side of the inner cavity of the bundled ventilation pipe 42 close to the blower 3 is fixedly connected to a catalytic cylinder shell 4 through a connecting ventilation pipe.

[0035] When using this device to treat waste gas, the waste gas is introduced into the interior of the device through the ventilation pipe 13. The waste gas first enters the interior of the incineration device 5. During this process, the holes on one side of the fixed disk 510 are staggered from the holes on the other side of the misaligned rotating disk 511. Therefore, when the ventilation pipe 13 is closed, the feeding rod 51 ignites the waste gas introduced into the inner cavity of the heat insulation chuck 55 by inputting clean fuel through the flame spraying rod 52 for complete incineration. During this process, the driving motor 58 controls the self-rotation of the heat insulation chuck 55 through the friction of the power rotating column 59, so that the metal sweeping rod 57 on the inner wall of the heat insulation chuck 55 continuously sweeps across the inner cavity of the heat insulation chuck 55, dispersing the waste gas residues accumulated in the inner cavity of the heat insulation chuck 55, so that the flame spraying rod 52 can fully burn the combustibles in the waste gas in a short time. During this process, because the left heat insulation chuck 55 rotates continuously, the burned waste gas will be discharged into the U-shaped rotating pipe 11 through the periodically connected fixed disk 510 and misaligned rotating disk 511, and then input into the interior of the extrusion catalytic barrel 2. After reacting with the catalyst to consume toxic substances, it is discharged from the air outlet pipe 14 to complete the waste gas treatment work.

[0036] Embodiment 2

[0037] Please refer to Figures 1-8 , the present invention provides a technical solution: on the basis of Embodiment 1, the anti-backflow device 6 includes an inner cylinder shell 61. A vertical hollow rod 62 is slidably connected to the axis of the inner cavity of the inner cylinder shell 61. A thrust spring 63 is sleeved on the top of the surface of the vertical hollow rod 62. The top end of the inner cavity of the intake rotating pipe 23 is fixedly connected with a sealed fixed shell 64. A sliding inner shell 65 is slidably connected to the inner cavity of the sealed fixed shell 64. The bottom end of the sliding inner shell 65 is slidably connected with a tensiometer 66 through a traction pull rod.

[0038] A side intake groove is opened at the bottom of the inner cavity of the vertical hollow rod 62. Vertical cutting grooves are uniformly opened at the top of the inner cavity of the sliding inner shell 65. The bottom end of the vertical hollow rod 62 is slidably connected to the top of the inner cavity of the intake rotating pipe 23 through an axial socket. The bottom end of the vertical hollow rod 62 is pressed against the top of the sealed fixed shell 64. The top end of the sliding inner shell 65 is slidably connected to the top of the inner cavity of the sealed fixed shell 64 through a connecting spring. The surface of the tensiometer 66 is fixedly connected to the top of the inner cavity of the intake rotating pipe 23. The surface of the inner cylinder shell 61 is fixedly connected to the bottom end of the inner cavity of the U-shaped rotating pipe 11. A filter plate 8 is arranged in the middle of the inner cavity of the U-shaped rotating pipe 11.

[0039] The filter plate 8 includes an externally connected pressure rod 81. At the axis of the top of the inner cavity of the externally connected pressure rod 81, a vertical connecting rod 83 is fixedly connected. The surface of the vertical connecting rod 83 is slidably connected with an adapted retaining disc 82. The surface of the adapted retaining disc 82 is fixedly connected with the middle part of the inner cavity of the U-shaped rotating pipe 11. The bottom end of the vertical connecting rod 83 is fixedly connected with a spring clamping plate 84. At the top of the inner cavity of the spring clamping plate 84, a strip-shaped filter plate 85 is fixedly connected. On one side of the inner cavity of the adapted retaining disc 82 close to the incineration device 5, an air extraction pump 86 is fixedly connected.

[0040] The pressurizing device 7 includes a folding cylinder shell 71. The bottom end of the folding cylinder shell 71 is fixedly connected with a sliding chassis 72. The top end of the folding cylinder shell 71 is fixedly connected with the top of the inner cavity of the extrusion catalytic barrel 2. At the top of the surface of the sliding chassis 72, a telescopic pull rod 73 is fixedly connected. At the axis of the inner cavity of the sliding chassis 72, a piston push plate 74 is slidably connected. The bottom end of the sliding chassis 72 is fixedly connected with a buffer plate 9.

[0041] The buffer plate 9 includes a flat buffer plate shell 91. In the middle of the inner cavity of the flat buffer plate shell 91, an adapter ring 92 is fixedly connected. The surface of the adapter ring 92 is rotatably connected with an arc-shaped rotating cylinder 93.

The top of the arc-shaped rotating cylinder 93 is fixedly connected with the top of the inner cavity of the flat buffer plate shell 91 through a spring belt.

[0043] Under normal circumstances, the exhausted gas after combustion enters the U-shaped rotating pipe 11 through the through holes of the fixed disc 510. When passing through the middle of the U-shaped rotating pipe 11, it undergoes a simple filtering operation through the strip-shaped filter plate 85. However, the middle part of the inner cavity of the filtered strip-shaped filter plate 85 will have a clogging problem. After a period of filtering operation, the input of the exhausted gas is stopped. The externally connected pressure rod 81 is pressed downward, and the vertical connecting rod 83 slides down along the inner cavity of the adapted retaining disc 82, pushing the strip-shaped filter plate 85 downward. At this time, the lateral air extraction pump 86 can reverse-extract the residues in the inner cavity of the strip-shaped filter plate 85, and then they fall to the bottom of the inner cavity of the adapted retaining disc 82.

[0044] The left end of the U-shaped transfer pipe 11 is normally separated from the intake transfer pipe 23. At this time, the thrust spring 63 pushes the vertical hollow rod 62 downward, so that the air groove at the top of the vertical hollow rod 62 enters the interior of the inner cylinder shell 61, and the inner cylinder shell 61 is in a sealed state. When exhaust is required, the entire U-shaped transfer pipe 11 is pressed downward through the external pressing rod 81. The material conveying rod 51 extends, and the surface of the driving motor 58 slides along the inner wall of the main processing box 1. When the left end of the U-shaped transfer pipe 11 descends, the bottom end of the vertical hollow rod 62 first inserts into the axis of the intake transfer pipe 23 directly below. Subsequently, the vertical hollow rod 62 rises along the inner cavity of the inner cylinder shell 61 under the pushing action of the reaction force. The bottom end of the vertical hollow rod 62 pushes the sliding inner shell 65 downward. At this time, the U-shaped transfer pipe 11 is connected to the intake transfer pipe 23 through the vertical hollow rod 62, and the two-sided tensiometers 66 monitor the descending height of the sliding inner shell 65.

[0045] During the catalytic reaction process, the catalytic cylinder shell 4 passes the VOCs gas in the inner cavity into the extrusion catalytic barrel 2 through the beam pipe 42. Then the blower 3 ventilates to prevent gas backflow. At this time, the two-sided telescopic pull rods 73 push the sliding chassis 72 downward. The sliding chassis 72 mixes and compresses the VOCs gas at the bottom and the toxic gas introduced from the right end. Subsequently, the shaft rod at the top of the rotating shaft fan blade 22 inserts into the inner cavity of the sliding chassis 72. During this process, the rotating shaft fan blade 22 continuously rotates to mix the gas, so that the toxic gas is fully purified. Subsequently, the top of the rotating shaft fan blade 22 pushes the piston push plate 74 upward, and the gas enters the interior of the folding cylinder shell 71 and is discharged to the outside of the device through the air outlet pipe 14 to complete the purification work.

[0046] During the continuous descent of the sliding chassis 72, the shaft rod at the top of the rotating shaft fan blade 22 first inserts into the axis of the flat plate shell 91. Subsequently, the shaft rod at the top of the rotating shaft fan blade 22 relatively rubs against the outer surfaces of the two-sided arc-shaped rotating cylinders 93, thereby causing the arc-shaped rotating cylinders 93 to rotate around the adapter ring 92. The pressing switch 94 below is pressed. At this time, the control magnetic plate 95 starts to work, endowing the bottom of the sliding chassis 72 with magnetism. There are also magnets in the inner cavity of the rotating shaft fan blade 22. The magnets on the upper and lower sides generate repulsive forces, making it increasingly difficult for the sliding chassis 72 to slide downward, thereby effectively preventing the problem that the sliding chassis 72 slides excessively, resulting in the fan blades of the rotating shaft fan blade 22 touching the sliding chassis 72 and causing damage to the fan blades.
