技术领域 technical field

The acid mist tower has the characteristics of being able to remove harmful gases in the air, wide application range, high purification efficiency, low equipment resistance, and small footprint. The acid waste gas is collected through the air pipe, and enters the acid mist tower by the twitch of the fan.

Since the alkali solution absorbs acid waste gas, the conductivity of the spray water in the acid mist tower will increase after a period of time, which will easily lead to The crystallization of the packing requires manual drainage and replenishment; it also requires manual regular inspection of the pH value of the acid mist tower spray, the liquid level of the alkali tank, etc., which is not only inconvenient to operate, but also increases the exposure of personnel to chemicals, which is not conducive to In good health.
