Furthermore, the bottoms of the front sides of the first absorption tower and the second absorption tower are respectively provided with a drain outlet, and a viewing mirror is arranged on the drain outlet.
Furthermore, the filler layer in the second absorption tower is activated carbon.
Compared with the prior art, the utility model has the following beneficial effects:
according to the utility model, the air blower communicated with the chimney is arranged to generate suction force to suck acid-base waste gas generated by reaction of materials in the reaction tank into the first absorption tower, the acid-base waste gas is fully neutralized, reacted and absorbed by absorption liquid in the first absorption tower, then the acid-base waste gas is discharged into the second absorption tower to be diluted and absorbed again, and the acid-base waste gas is discharged after peculiar smell is removed, so that the effect of thoroughly removing harmful substances in the acid-base waste gas is achieved.
