Abstract
A liquid spray-type stack gas clarifier is adapted to be mounted within existing stacks and supported therein from the top of the stack structure. Means are provided for maintaining gas flow velocity within the stack to compensate for pressure changes resulting from the cooling effect of the liquid spray curtain discharged into the stack to entrain and absorb particulate and gaseous pollutants from the stack gas. The spray liquid and absorbed pollutants are collected within and drained from the stack, and means may be provided for shielding existing stack structure from adverse effects of the scrubbing liquid.
