Abstract
The self-controlling waste gas purifying device of the utility model mainly is composed of a tower body (2), a purifying layer (3), a spraying ring (7), a demisting layer (8), a defoaming plate (12). The purged liquor stored at the bottom of the tower body is pumped by a circulating pump (13) and sprays to moisten the surface of the plastic stuffing (6) in the purifying layer (3) through the spraying ring (7); the backward exhaust gas is thoroughly contacted and reacted with the moistened surface of the plastic stuffing to create multiform salt, and the salt is quickly dissolved in the purged liquor or deposited at the bottom of the tower body by creating solid particles; the exhaust gas treated by these two stages of purifying process is demisted by the demisting layer (8) and defoamed by the defoaming plate, and finally exhausted to the atmosphere through the chimney on the tower top. The exhaust gas purification rate of the purifying device reaches the emission standard. This device has the advantages of reasonable structure, small exhaust gas resistance, big gas-liquid flow rate and lower manufacturing cost, having a preferable accomplishment effect and social and ecnomic benefits. So the utility model can be widely used in the field of waste gas treatment for industries such as metallurgy, electric plating, chemical industry, pharmacy, etc.
