Spray tower is a kind of waste gas treatment equipment, which is often used for industrial waste gas treatment. Usually, there are a lot of acid mist waste gas, so it is also called acid mist waste gas tower. The spray tower can not only treat acid mist waste gas, but also other waste gases, such as ammonia (NH3) hydrogen sulfide waste gas, VOC organic waste gas, domestic waste gas, waste combustion waste gas or dust.

Taking the treatment of acid mist waste gas as an example, the working principle, characteristics and structure of spray tower are briefly introduced.

The acid mist waste gas is introduced into the purification tower from the air duct and passes through the packing layer, and the waste gas fully contacts, absorbs and neutralizes with the sodium hydroxide absorption solution. After the acid mist waste gas is purified, it is dehydrated and demisted by demisting plate, and then discharged into the atmosphere by fan. The absorption liquid is pressurized by the bottom water pump, sprayed to the top of the tower, and finally returned to the bottom of the tower for recycling. The purified acid mist waste gas meets the emission requirements of the emission standard and is lower than the national emission standard.

Characteristics of spray tower

1, high dust removal and desulfurization efficiency. When alkaline washing water is used, the desulfurization efficiency can reach 85%.

2, the equipment occupies less land and is convenient to install.

3. The indicators of water consumption and power consumption are low.

4, corrosion resistance, no wear, long service life.

5. The equipment is reliable and easy to maintain.
