[0033] Specifically, when the exhaust gas is treated in a humid environment, the exhaust gas enters the pulse bag dust collector 1 through the air inlet pipe, and then the exhaust gas moves upward, thereby passing through the filter element 21, and the filter element 21 will filter out the impurities in the exhaust gas, thereby treating the exhaust gas, and the treated exhaust gas will be discharged from the outlet 19.

Because the threaded shaft is fixedly connected to the rectangular plate 32, when the threaded shaft rotates and descends, the movable plate 31 will also descend. When the movable plate 31 descends, the brush assembly 34 The entire filter element 21 will be cleaned. When the movable plate 31 moves to the bottom, the threaded rod 18 will reverse to allow the movable plate 31 to rise, and finally the movable plate 31 will be brought to the inside of the recovery tank 22. At this moment, the motor 17 and the motor 345 will stop. At this time, the swept impurities will fall to the bottom of the pulse bag dust collector 1. Finally, the dust discharge port 15 will be opened to discharge the dust from the inside of the pulse bag dust collector 1, thereby achieving the effect of allowing the pulse bag dust collector 1 to clean the filter element 21 even in a humid environment.
