After the connection, the waste gas can be injected into the box body 1 through the air inlet 19. At the same time, the exhaust fan 8 is connected to the external power supply for operation. The exhaust fan 8 can discharge the air in the box body 1 into the external transportation pipeline under the guidance of the filter cartridge 3, the bellows 4 and the pipe body 5. At this time, since the waste gas enters the box body 1, the waste gas will be filtered by the filter cartridge 3 and the suction factor of the exhaust fan 8 and discharged into the external transportation pipeline. At this time, the dust removal and filtration processing work of the waste gas is completed. When the filter cartridge 3 is blocked due to the filter material, the push rod 10 drives the plate body 9 and the two groups of filter cartridges 3 to move downward, and the two groups of filter cartridges 3 will be at the corresponding opening 2. Insert it into the corresponding dust removal filter bag 13 and place it. After placement, close the connection between the exhaust fan 8 and the pipe body 5 with the solenoid valve 7, and connect the air intake fan 6 to the external power supply for operation. The air intake fan 6 will suck the airflow into the pipe body 5 and inject it into the two groups of filter cartridges 3 under the guidance of the pipe body 5 and the bellows 4. The airflow will pass through the mesh on the filter cartridge 3 and enter the dust removal filter bag 13. At this time, the airflow can flush the filtered matter blocked on the filter cartridge 3 into the dust removal filter bag 13 for collection and storage. When the cleaning is completed, the push rod 10 drives the two groups of filter cartridges 3 to move up and reset, cancel the threaded connection between the ring body 12 and the threaded sleeve 11, take out the filtered matter in the dust removal filter bag 13, and then the exhaust gas treatment work can be carried out again.
