Cyclonic scrubbers

​Cyclonic spray scrubbers are used to help in air pollution control and they use the features of a spray chamber and a dry cyclone to remove pollutants from gas streams. The inlet gas enters the chamber tangentially, swirls through in a corkscrew motion, and exits while liquid is sprayed inside the chamber. As the gas swirls around the chamber, pollutants collide with the liquid and are removed by the droplets as they are thrown to the walls, and washed back down and out.
