ABSTRACT:
An arrangement for intercepting entrained contaminants from a gaseous medium in a scrubbing liquid has a whirling chamber, a droplet-separating passage, and an impeller arranged coaxially downstream of one another. The whirling chamber has a constant-width inner annular zone and an outer annular zone surrounding the inner annular zone and decreasing in its axial width in the radially outward direction. A housing surrounds the impeller and/or the passage and is either cylindrical or spiral-shaped or partly both, and in the latter event the differently shaped parts of the housing are separated by a partition which has a central orifice of a smaller diameter than that of the impeller. The contaminated gaseous medium is admitted into the whirling chamber tangentially thereof and droplets of scrubbing liquid are introduced into the whirling chamber through a plurality of apertures arranged in an annular fashion for the scrubbing liquid to become admixed with the gaseous medium and to thus intercept the contaminants therefrom. A stripping slot is formed at the downstream end of the passage between the casing bounding the same and an inlet nozzle of the impeller.
