Acid alkali waste gas treatment unit
At present, most corrosive gases (such as acid and alkaline waste gas) are treated by liquid absorption method. The acid mist waste gas is introduced into the purification tower through the air duct. After passing through the packing layer, the waste gas and the sodium hydroxide absorption solution are fully contacted by the 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 from the tower top after being pressurized by water pump at the tower bottom, and then returns to the tower bottom for recycling.

Equipment principle
At present, most corrosive gases (such as acid and alkaline waste gas) are treated by liquid absorption method. The acid mist waste gas is introduced into the purification tower through the air duct. After passing through the packing layer, the waste gas and the sodium hydroxide absorption solution are fully contacted by the gas-liquid two-phase absorption and neutralization reaction.

The absorption liquid is sprayed down from the tower top after being pressurized by water pump at the tower bottom, and then returns to the tower bottom for recycling.
Equipment characteristics
This equipment uses a 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 (spiral demister);
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 remove the odor and harmful substances in the gas.
