The acid-base gas is sprayed out through the spray pipe 14 to be sprayed and neutralized. At the same time, the sound-absorbing pad 17 is used to absorb and reduce the noise generated when the delivery pump 18 is working. The treated acid-base waste gas is further adsorbed by the adsorption layer 16 and then discharged from the equipment through the outlet channel 6.
