Abstract

Dust is removed from a gas using a venturi washer of variable section obtd. by means of a layer of liq. laid against the convergent wall and against the throat of the venturi washer. The thickness of the layer is adjusted depending on the gas flow. The washer is constituted by a venturi and a liq. atomiser. The gas is introduced at high speed into the convergent part of the venturi. The atomiser is situated in the convergent part and is capable of producing droplets of fluid for catching the dusts. The dia. of the venturi is adjusted by feeding liq. to create a layer of fluid of variable thickness against the convergent wall and the throat of the venturi. The plant includes means of retaining the droplets charged with dusts and of discharging the gas from which the dust has been removed. Used for the purificn. of industrial fumes before discharge to atmos. They are less complicated and easier to operate than existing processes and plant in which the problem of obtaining satisfactory coating of the dusts at different gas rates is resolved by the use of a number of washers or by mechanical devices for adjusting the dia. of the throat of the venturi.
