Brady, J D; Graves, K M

Gas scrubbing apparatus for removing sulfur dioxide from a gas stream with a cleaning liquid capable of absorbing the sulfur dioxide in the gas stream comprising a housing defining scrubbing chamber therein, a plurality of baffles in the scrubbing chamber at longitudinally spaced positions therealong for generating turbulence in the gas stream and rotating the gas stream about the central axis of the scrubbing chamber, spray means for spraying the cleaning liquid into the scrubbing chamber between the baffles to absorb the sulfur dioxide from the gas stream, and a mist eliminator downstream of the baffles to remove liquid droplets from the gas stream. The baffles are oriented so that each baffle rotates the gas stream approximately ninety degrees about the central axis of the scrubbing chamber as the gas stream flows thereby with all of the baffles rotating the gas stream in the same direction about said central axis. The apparatus also includes quenching means for cooling and saturating the gas stream prior to passage into the scrubbing chamber. Filtration means may also be provided for removing submicron and larger particulates from the gas stream after passage through the scrubbing chamber.
