At the same time, the tail gas to be processed is discharged into the box 1 through the air inlet 21. After the tail gas is fully neutralized, filtered and purified by the multiple atomizing nozzles 605 and the tail gas filter plate 10, it is directly discharged from the exhaust port 20 on the other side of the box 1. During the neutralization operation, the atomized neutralizing liquid will condense into neutralization waste liquid on the surface of the inclined plate 11 and accumulate on the surface of the inclined plate 11. When the neutralization operation is completed, After completion, the second drive motor 13 can be started to drive the movable plate 16 to open. With the cooperation of the limit plate 15, the second through hole 18 set on the surface of the movable plate 16 will overlap and open the first through hole 12 of the inclined plate 11, so that the accumulated waste liquid falls into the bottom of the box body 1. At the same time, the first drive motor 7 can be started to drive the scraper holder 9 to scrape and clean the impurities attached to the surface of the exhaust gas filter plate 10. The hanging impurities also fall on the inclined plate 1906 at the bottom of the box body 1.
