FRP industrial waste gas purifier is a more effective kind of waste gas purifier. The main purification process is that the waste gas is led out from the air pipe and pressurized by the fan and sent to the absorption purification tower. The pollutants in the gas are absorbed and purified in the purification tower, and the purified gas is evacuated through the smoke pipe on the top of the tower. The absorption liquid in the FRP industrial waste gas purification tower adopts about 6-10% NaOH or NaCO3 solution. After being pressurized by the circulating pump in the circulating water tank at the bottom of the tower, it is sprayed down from the top of the tower, contacted with gas-liquid countercurrent, and then flows to the bottom of the tower together with the absorbed pollutants for recycling.

The process and equipment can be widely used in the purification of acid and alkaline waste gas discharged in chemical industry, electronics, metallurgy, electroplating, textile (chemical fiber), food, machinery manufacturing and other industries. Such as seasoning food, acid making, pickling, electroplating, electrolysis, battery, etc.
