A Venturi Scrubber has two cones placed vertically with a narrow throat joining the two. The gas enters the top cone (converging section) where it is sprayed with water. Both then converge at the narrow aperture of the throat where the velocity of the gas increases and there is heavy pressure drop creating a turbulent condition. This mixture then moves to the bottom cone (diverging section) where the water turns into fine drops and the mixture moves into the re-circulation tank.
