Venturi Scrubber

A venturi scrubber is an air pollution control device that uses the energy of a high-velocity inlet gas stream to atomize the liquid used to scrub the stream, and it belongs to the broader group of air pollution controls known as wet scrubbers. Gas is forced through a narrowing throat section, which accelerates its velocity and creates strong turbulence that brings the gas into intimate contact with fine liquid droplets, allowing particles and some gaseous pollutants to be captured by the liquid before it is separated back out downstream. This reliance on the gas stream itself to atomize the scrubbing liquid, rather than a separate spray system, distinguishes venturi scrubbers from other wet scrubber designs such as packed or plate towers, which rely on other mechanisms and tend to be more efficient for gaseous absorption specifically even as venturi scrubbers excel at particle removal through their high-velocity turbulent contact.
