Abstract

Abstract A process for the separation of solid and/or liquid particles from gases or solids from liquids, as well as for the separation of gases or liquids with different densities is proposed, in which a Venturi tube is used. The gas and/or liquid mixture is introduced inwards in radially symmetrical manner from the outside through the slot of an annular nozzle at a high flow velocity which, in the case of gases, extends up to the velocity of sound. The gas is subject to the action of a high centrifugal acceleration in the slot, which has a radius of curvature of approximately 1 to 100 mm.
