Abstract
Scrubbing apparatus for effecting contact between polluted air and a scrubbing liquid may define a serpentine path mounted on a rooftop, an upright tank having a central depending outlet conduit or an upright tank in which contact between the polluted gas and the scrubbing liquid is effected by projecting the scrubbing liquid onto a rotating propeller to effect atomization of the scrubbing liquid. Purification of the scrubbing air is enhanced by producing turbulence in the air carrying the scrubbing liquid by passing the air carrying the scrubbing liquid between closely adjacent, flexible, vibrating sheets disposed parallel to the gas flow. The vibrating characteristics of the flexible sheets can be altered by stretching such sheets and/or by placing such sheets alongside a hard surface struck by the flexible sheets.
