[0027] Preferably, a filling port 21 is installed on the outer side of the washer liquid tank 1 , and an air inlet 22 is installed on the left side of the washer liquid tank 1 .

[0028] Working principle: the waste gas enters the washing tower 2 through the air inlet 22, and the second pump 11 works. The second liquid extraction pipe 12 will suck the washing liquid in the washing liquid tank 1 on the upper part of the partition plate 3, and then spray it through the spray pipe 13, and the sprayed washing liquid will fall back into the washing liquid tank 1.
