A method and apparatus for scrubbing gases with liquid. It employs at least one nozzle which discharges a stream of gas downwardly against the surface of a body of scrubbing liquid (e.g., water). The nozzle is made with converging flat side walls to provide an elongated discharge opening which extends horizontally over the body of scrubbing liquid. The impingement of the discharging gas upon the liquid body serves to depress the surface of the liquid to form a trough-like region. Some scrubbing action is caused by such impingement, and the impingement causes some of the liquid to be entrained in the gas flow whereby a gas-liquid mixture flows in opposite lateral directions from the sides of the trough-like region. The nozzle is provided with shield means whereby the movement of gas and entrained liquid from the trough-like region is confined. Preferably the method and apparatus makes use of a plurality of such nozzles disposed side by side. |
