An Acid Fume Scrubber, also known as an acid gas scrubber or simply a fume scrubber, is a pollution control device used to remove acidic gases (such as sulfur dioxide, hydrogen chloride, and hydrogen fluoride) and other hazardous chemical fumes from industrial exhaust streams. These systems are crucial in mitigating air pollution and protecting the environment and human health, especially in industries where corrosive or toxic gases are produced.An acid fume scrubber working process:1.Inlet: The polluted air, laden with acidic fumes, is drawn into the scrubber from an industrial process through an inlet duct.2.Contact with Scrubbing Solution: Inside the scrubber, the polluted air comes into contact with a liquid scrubbing solution. This solution is often water-based and may contain various chemicals or additives depending on the specific pollutants to be removed. The scrubbing solution can neutralize or chemically react with the acidic gases.3.Absorption and Reaction: As the acidic fumes come into contact with the scrubbing solution, chemical reactions occur, leading to the removal of the acid gases from the air. For example, in the case of sulfur dioxide (SO2) removal, the reaction might produce sulfuric acid (H2SO4), which is then dissolved in the liquid solution.4.Separation: The cleaned air, now largely free of acid gases and other pollutants, exits the scrubber through an outlet duct and is released into the atmosphere or further treated if necessary.5.Treatment of Scrubbing Solution: The liquid scrubbing solution, now containing absorbed pollutants, needs to be treated or regenerated for continuous use. Depending on the specific system, this can involve chemical reactions, pH adjustment, or additional treatment steps to recover or neutralize the absorbed pollutants.
