Top 7-9 centimetre of said aqueous vapor separation control bushing 4a is provided with second aqueous vapor separation control bushing 4b, controls bushing 4b second aqueous vapor separation and is uniformly distributed with several leakage holes two 8b, and the aperture of leakage hole two 8b is the 8-10 millimeter.Second aqueous vapor separated the control bushing, on first basis, strengthened the effect that aqueous vapor is separated more; The fused time of waste gas and water is longer; Acid group, carbon monoxide, sulfur dioxide are adsorbed in the water liquid, fused more abundant, reach better exhaust-gas treatment effect.
The following bottom direction of aqua storage tank 7 of leaning on of said aqueous vapor exchange pipe 2 is uniformly distributed with several aqueous vapor exchange holes 3.Aqueous vapor exchange hole 3 is the contacts area that increased waste gas and water, the contacting with water of stereoscopic and omnibearing.Said aqueous vapor exchange pipe 2 is made as the 10-15 root; These aqueous vapor exchange pipes 2 add several aqueous vapor exchange holes 3; Increase thousands of times contact area than traditional shower, added that roots blower increases the effect of blast, in aqua storage tank, formed some gas columns; Make the fusion of water and waste gas more thorough, more comprehensive.
The waste gas that described gas sampling pipe 6 is collected is acid mist, carbon monoxide, sulfur dioxide, but is not limited to.
Described aqua storage tank 7 is an anticorrosive, for a kind of in plastics, fiberglass, polyethylene, the stainless steel but be not limited to.
Described aqua storage tank 7 is for square, circular or taper but be not limited to;
Said waste gas is acid mist, and the material of aqua storage tank 7 is plastics, in aqua storage tank 7 water, adds alkali, and pH value is 10-14.
