METHOD AND EQUIPMENT FOR GAS CLEANING BY SCRUBBING WITHIN A VENTURI COLUMN

摘要

Method for the cleaning of a gas (G) contaminated with liquid and/or solid particles using a venturi column with a vertical axis. The method consists in: pneumatically spraying the throat (3) of the venturi device with a scrubbing liquid in an ascending stream of said gas, the scrubbing liquid being injected in a direction substantially perpendicular to that of said stream; eliminating, downstream of said throat, the scrubbing liquid vesicles carried by the gaseous stream and laden with contaminants. The method is characterized in that a sonic field is generated in the region of the venturi throat (3) to force shifting of the contaminating particles in relation to the scrubbing liquid vesicles. The present invention also concerns a venturi column for carrying out said method.
