Acid alkali waste gas tower

Principle of acid-base waste gas tower

The principle of acid-base waste gas tower is mainly to convert acidic or alkaline substances in the waste gas into neutral substances through acid-base neutralization reaction, thereby eliminating their pollution to the environment. Acid alkali waste gas towers are usually composed of multiple tower bodies, each with nozzles inside that spray corresponding neutralizing liquids to react with acidic or alkaline substances in the waste gas. At the same time, the tower body is also equipped with packing and exhaust systems to ensure the progress of neutralization reactions and effective removal of exhaust gases.

When the waste gas enters the acid-base waste gas tower, the neutralizing solution is sprayed out through the nozzle and undergoes neutralization reaction with acidic or alkaline substances in the waste gas, generating neutral substances and water. At the same time, the neutralizing liquid on the packing material will adsorb, absorb, and react with other pollutants in the exhaust gas, further removing harmful substances from the exhaust gas. Finally, the exhaust system discharges the treated exhaust gas and replenishes an appropriate amount of fresh air into the tower to ensure the neutralization reaction and effective removal of exhaust gas. In summary, the acid-base waste gas tower is an effective method for treating waste gas containing acidic or alkaline substances. The principle is to convert acidic or alkaline substances in exhaust gas into neutral substances through acid-base neutralization reaction, thereby eliminating their pollution to the environment.
