ABSTRACT
Venturi scrubbers are applied to air pollution control problems where very high collection efficiencies are required and where most of the particulate matter being removed is smaller than 2 µm in diameter. There are a number of applications where venturi scrubbers are the only technically feasible solution to an air pollution problem. Performance of venturi scrubbers is independent of particle resistivity, and they can often be used in applications where electrostatic precipitators cannot be used due to the inability to put a static charge on a particle. The mechanisms affecting collection of particulates in venturi scrubbers are numerous. While the predominant application of venturi scrubbers is in the collection of particulate matter from gas streams, they can also be used for gas absorption. Venturi scrubber applications in steel mills usually require high pressure drops. The iron foundry industry uses venturi scrubbers to collect emissions from electric furnaces and from cupola furnaces. Venturi scrubbers are commonly used in inorganic chemical plants.
