A gas-scrubbing apparatus for treating contaminated gas with a liquid to remove particulates and other impurities. Liquid is discharged radially outwardly from a central nozzle or jet and is directed between a pair of upper and lower walls which converge radially outwardly, and then diverge radially outwardly, to define an annular venturi. Gas flowing upwardly through a central opening in the lower wall passes outwardly through the venturi where it intimately mixes with the liquid discharged from the nozzle. In one embodiment, the upper wall has a trough-shaped upper surface communicating directly with the throat of the venturi for introducing recirculated liquid into the liquid-gas mixture flowing outwardly through the venturi. |
