PP spray tower process and waste gas treatment equipment can be widely used in chemical, electronic, metallurgical, electroplating, textile (chemical fiber), food, machinery manufacturing and other industries in the process of acidic and alkaline waste gas purification. Such as seasoning food, acid making, pickling, electroplating, electrolysis, storage battery, etc.

The acid mist waste gas of pp spray tower is introduced into the purification tower through the air duct. After passing through the packing layer, the waste gas and sodium hydroxide absorption liquid are fully contacted by gas-liquid two-phase absorption and neutralization reaction. After purification, the acid mist waste gas is dewatered and demisted by the demister and then discharged into the atmosphere by the fan. The absorption liquid is sprayed down the tower top after being pressurized by water pump at the tower bottom, and finally returns to the tower bottom for recycling. The purified acid mist exhaust gas meets the emission requirements of the local emission standards of Guangdong Province and is lower than the national emission standards.

PP spray tower adopts packed tower to purify waste gas, which is suitable for the treatment of continuous and intermittent exhaust gas; The process is simple, and the management, operation and maintenance are quite convenient and simple, which will not affect the production of the workshop; It can be widely used to purify various pollutants at the same time; Low pressure drop, large operating flexibility, and good demisting performance; The tower body can be made of FRP/PP/PVC and other materials according to the actual situation; The packing adopts high efficiency and low resistance Bauer ring, which can completely remove the odor and harmful substances in the gas.
