Method and apparatus for filtering an air stream using an aqueous foam with nucleation.

摘要

Procedure filtering contaminants super and submicron a stream of contaminated air, wherein: said contaminated air stream passes into and through a contained aqueous solution, in which an aqueous foam is generated from said aqueous solution and continuously maintained above said aqueous solution contained forming said aqueous foam a washing chamber in which contaminants are trapped inside bubbles of said aqueous froth, and wherein said contaminated air stream passes through said aqueous foam , characterized in that: a fine mist of aqueous solution is produced from nozzle (s) nebulizer (as) (750) and the fine mist into said contaminated air stream is introduced prior to said contaminated air stream between in said aqueous foam, saturating said fine mist said contaminated air stream, the aqueous foam is cooled thereby trapping contaminants in mic rogotas of liquid, suspended in air, inside bubbles of aqueous froth, these pollutants are removed from said air stream onto the surfaces of the bubbles of aqueous foam bringing said contaminants into contact with the liquid surfaces of said foam bubbles aqueous in said wash chamber; said contaminants are transferred from the surfaces of said aqueous froth bubbles in said scrubbing chamber to a reservoir of said aqueous solution and the decontaminated air stream is discharged.
