A venturi scrubber is designed to effectively use the energy from the inlet gas stream to atomize the liquid being used to scrub the gas stream. This type of technology is a part of the group of
air pollution controls collectively referred to as
wet scrubbers.
Venturi devices have also been used for over 100 years to measure fluid flow (
Venturi tubes derived their name from
Giovanni Battista Venturi, an Italian physicist). About 35 years ago, Johnstone (1949) and other researchers found that they could effectively use the venturi configuration to remove particles from gas streams. Figure 1 illustrates the classic venturi configuration.
