Air scrubber design exhaust gas spray tower
Product Description
The air scrubber design exhaust gas spray tower fully contacts the waste gas with the liquid and uses its solubility in water or chemical reaction to reduce its concentration, thereby becoming a clean gas that meets the national emission standards. It is mainly used to treat inorganic waste gas, such as sulfuric acid mist, hydrogen chloride gas, nitrogen oxide gas with different valence states, dust waste gas, etc.
Working Principle
The working principle of air scrubber design exhaust gas spray towers can be divided into three forms: co-current, counter-current, and cross-current. Among them, the most commonly used is countercurrent spraying: acid or alkaline acid mist waste gas is introduced into the purification tower through the air duct, passes through the packing layer, and the waste gas is fed from the bottom of the tower. continuous through the voids of the packing layer. On the surface of the filler, the gas-liquid two phases are fully contacted to absorb and neutralize the reaction to adsorb the acidic or alkaline pollutants contained in the exhaust gas. After the acid mist exhaust gas is purified, the clean gas is discharged from the fan into the atmosphere after dehydration and demisting by the defogging plate. Insoluble viscose particles and dust are poured into the collection tank, suspended particles are discharged from the overflow outlet, and the collected sediment is discharged from the sewage outlet. The absorption liquid is pressurized by the water pump at the bottom of the tower and sprayed down at the top of the tower, and finally refluxed to the bottom of the tower for recycling.
Advantages
The air scrubber design exhaust gas spray tower has low noise, stable operation, and simple and convenient operation; the water-washing waste gas treatment system is cheap and the treatment method is simple; the gaseous, liquid and solid pollution sources can be treated; the system has a low-pressure loss, suitable for large air volume; Type filling layer design to deal with mixed pollution sources. It can treat acid and alkaline waste gas economically and effectively, and the removal rate can be as high as 92% or more.
Applications
Electronic industry, semiconductor manufacturing, PCB manufacturing, LCD manufacturing, steel metal industry, electroplating and metal surface treatment industry, pickling process, dye/pharmaceutical/chemical industry, deodorization/chlorine neutralization, combustion exhaust gas SOx/NOx Removal and treatment of other water-soluble air pollutants.
