This disassembly method saves time and effort. At the same time, it is also convenient for users to quickly complete the replacement of the zeolite rotor, thereby prompting the zeolite rotor adsorption unit to be used continuously, greatly improving the practicality of the device.

At this time, the purified gas will push the air baffle plate to squeeze the pressure sensor. When the thrust applied to the pressure sensor is lower than the set value, it can detect that the super-efficiency filter or the zeolite wheel is seriously blocked, so that it is convenient for the staff to clean the surface of the super-efficiency filter or the zeolite wheel in time. Finally, through the coordinated use of the VOCs detector and the pressure sensor, the entire device can have the function of online monitoring, which is convenient for the user to maintain the waste gas treatment device in time, greatly improving the service life of the device.
[0023] 4.

[0024] 5. This zeolite molecular sieve adsorption and desorption integrated waste gas treatment device, through the set graded premixed catalytic combustion unit, first the transmission pipe will transmit the desorbed high-concentration VOCs to the incineration box, then the rotation of the main gear will drive the upper slave gear to rotate, the rotation of the upper slave gear can drive the upper slave rod to rotate, the rotation of the upper slave rod can drive the inner stirring plate and the outer stirring rod to rotate at the same time, through the rotation of the inner stirring plate and the outer stirring rod, the VOCs and air can be quickly mixed, so that the VOCs are evenly distributed in the transmitted gas, and then the middle slow plate can transmit the transmitted gas at a slow speed, and then the burner can be controlled to start to convert the VOCs in the transmitted gas into carbon dioxide and water, and finally the zeolite molecular sieve will filter and discharge the treated gas again, so that the waste gas is treated twice, which greatly improves the purification quality of the waste gas by the entire device.

[0055] During operation, the exhaust gas is initially filtered: first, the super-efficient filter 304 can efficiently filter the particulate matter in the exhaust gas, so that the preliminary treatment of the exhaust gas is quickly completed, and then the fan blade 317 is rotated by the large amount of exhaust gas introduced into the air inlet pipe 302, and the rotation of the fan blade 317 can drive the brush 318 to rotate, and the rotation of the brush 318 can clean the blocked surface on the left side of the super-efficient filter 304, so that the super-efficient filter unit 3 has a self-cleaning function, which greatly improves the filtration efficiency and quality of the super-efficient filter unit 3 for the exhaust gas;
[0056] Exhaust gas adsorption: First, the zeolite rotor 404 can adsorb VOCs in the exhaust gas, and then the control motor 2 414 is started to drive the main gear 415 to rotate, and the rotation of the main gear 415 can drive the driven gear ring 412 and the zeolite rotor 404 to rotate at the same time. The rotation of the zeolite rotor 404 can cause the hot air to continuously desorb the VOCs on its surface, and the rotation of the zeolite rotor 404 can also cause the cold air to quickly cool down the heating area of the zeolite rotor 404, so that the zeolite rotor 404 can continuously adsorb VOCs in the exhaust gas, greatly improving the working efficiency of the zeolite rotor adsorption unit 4;
[0057] Exhaust gas desorption: First, the cold air pipe 703 can transmit the cold air from the outside to the desorption box 702 on the left, and the desorption box 702 on the left then transmits the cold air to the desorption box 702 on the right through the zeolite wheel 404. The desorption box 702 on the right then transmits the cold air to the heat exchange tube 704. At this time, the control heater 705 is started to convert the cold air passing through the heat exchange tube 704 into hot air, and the converted hot air will be transmitted through the desorption box 702 on the left. To the desorption box 702 on the left, and the hot air passing through the zeolite rotor 404 will quickly complete the desorption of VOCs in the holes of the zeolite rotor 404, and the desorbed VOCs will be transmitted to the next process through the transmission pipe 706, so that the desorption work of the zeolite rotor 404 is quickly completed. At the same time, the desorption and cooling of the zeolite rotor 404 are quickly completed through the continuous exchange of hot air and cold air on the surface of the zeolite rotor 404, which can improve the utilization rate of the zeolite rotor 404;
[0058] Online monitoring: First, the VOC detector 601 can monitor the purified gas passing through the exhaust pipe 809, so that it can monitor in real time whether the VOCs content in the purified gas meets the emission standards, which greatly improves the user experience. Then, the air blocking plate 604 can partially block the purified gas passing through. At this time, the purified gas passing through will push the air blocking plate 604 to squeeze the pressure sensor 603. When the thrust received by the pressure sensor 603 is lower than the set value, it can be detected that the super-efficient filter 304 or the zeolite wheel 404 is seriously blocked, so that it is convenient for the staff to clean the surface of the super-efficient filter 304 or the zeolite wheel 404 in time. Finally, the coordinated use of the VOC detector 601 and the pressure sensor 603 can enable the entire device to have the function of online monitoring, so that it is convenient for the user to maintain the exhaust gas treatment device in time;
[0059] Incineration catalysis: First, the transmission pipe 706 will transmit the desorbed high-concentration VOCs to the incineration box 801. At this time, the rotation of the main gear 415 will drive the upper slave gear 803 to rotate. The rotation of the upper slave gear 803 can drive the upper slave rod 802 to rotate. The rotation of the upper slave rod 802 can drive the inner stirring plate 804 and the outer stirring rod 805 to rotate at the same time. The rotation of the inner stirring plate 804 and the outer stirring rod 805 can quickly complete the mixing of VOCs and air, thereby promoting the VOCs to be evenly distributed in the transmitted gas. Then, the middle slow plate 806 can transmit the transmitted gas at a slow speed, and then control the start of the burner 807 to convert the VOCs in the transmitted gas into carbon dioxide and water. Finally, the zeolite molecular sieve 808 filters the treated gas again and discharges it, thus performing secondary treatment on the exhaust gas.
[0060] The removal and replacement of the super-efficient filter 304 are as follows: first, the rocker arm 314 is controlled to reverse and disengage from the surface of the half clamping ring 306. At this time, pulling the handle bar 312 upward can drive the super-efficient filter 304 to disengage from the inner cavity of the assembly hole 303, thus quickly completing the removal of the entire super-efficient filter 304. Then, the handle bar 312 is controlled to move downward. The downward movement of the handle bar 312 can squeeze the lower ends of the two upper movable plates 311 at the front and rear to move in opposite directions. The movement of the lower ends of the two upper movable plates 311 in opposite directions can drive the front and rear lower support blocks 310 to move in opposite directions. The movement of the front and rear lower support blocks 310 in opposite directions can drive the two half clamping rings 306 to disengage from the inner cavities of the two slots 305. At this time, the super-efficient filter 304 can be quickly separated from the half clamping rings 306, thereby facilitating the user to replace the three super-efficient filters 304. The two half clamping rings 306 are respectively disassembled and replaced, and the disassembly and replacement of multiple filter screens are relatively convenient. Then, the four fingers of both hands drag the two half clamping rings 306 respectively, and the thumbs of the two hands press the handle 312 respectively to drive the two half clamping rings 306 to move in opposite directions. At this time, the two half clamping rings 306 are clamped into the positions of the two clamping grooves 305 again, and the handle 312 is released. The elastic force of the spring 1 309 will pull the two half clamping rings 306 to move in opposite directions. When the two half clamping rings 306 are clamped into the inner cavity of the clamping groove 305 again, the three super-efficient filter screens 304 are locked again. The super-efficient filter screen 304 is inserted into the inner cavity of the assembly hole 303 again, and the rocker 314 is controlled to rotate forward. When the rear end of the rocker 314 moves into the screw groove at the front end of the half clamping ring 306 in front, the installation and replacement of the super-efficient filter screen 304 is quickly completed.
[0061] Disassembly and replacement of zeolite rotor 404: First, control motor 1 411 to reverse and drive main adjusting rod 410 to reverse and drive two guide plates 405 and two snap rings 403 to move in opposite directions at the same time. When two snap rings 403 are fully out of the grooves on both sides of zeolite rotor 404, pulling handle 417 forward can drive center bearing 409 and zeolite rotor 404 to move forward at the same time. The forward movement of zeolite rotor 404 can drive slide 408 to move in rail 407. When slide 408 is fully out of the inner cavity of rail 407, disassembly of zeolite rotor 404 can be completed quickly. This disassembly method saves time and effort. Then slide 408 is inserted into the inner part of rail 407 again and handle 417 is pushed to move backward. The backward movement of handle 417 can drive zeolite rotor 404 to move backward to the initial position. Then control motor 1 411 to rotate forward and drive The main adjustment rod 410 rotates forward, and the forward rotation of the main adjustment rod 410 can drive the two retaining rings 403 to move in opposite directions. When the ends of the two retaining rings 403 that are close to each other are fully inserted into the grooves on both sides of the zeolite rotor 404, the replacement of the zeolite rotor 404 is quickly completed, thereby enabling the zeolite rotor adsorption unit 4 to be used continuously. Among them, when the retaining ring 403 moves, the camera 416 will be controlled to start. When the camera 416 is started, it is convenient for the staff to remotely observe the meshing position of the driven gear ring 412, the main gear 415 and the upper slave gear 803. If misalignment occurs, the motor 2 414 will be controlled to start. When the motor 2 414 is started, it can drive the main gear 415 to rotate. When the gear teeth on the main gear 415 are meshed with the tooth grooves on the driven gear ring 412, and the gear teeth on the main gear 415 are meshed with the tooth grooves on the upper slave gear 803, it is convenient to complete the connection between the zeolite rotor adsorption unit 4 and the staged premixed catalytic combustion unit 8.
