Abstract
A multiphase scrubber for the wet scrubbing of gases in several different phases comprises at least three separate basic scrubbing units so that the scrubbing of the gas is carried out in at least three, advantageously six, successive steps. The droplet separation of the scrubbed gases is carried out in a uniform cyclone-like droplet separator composed of several nested cylinders. A clean dropless gas contains a dust content below the acceptable limit. The scrubber is suited for scrubbing hot furnace gases from closed reduction furnaces.
