ABSTRACT:
The invention relates to a method according to which the wet scrubbing of a gas flow is performed in at least three, advantageously six successive steps or phases, and the droplet separation of the scrubbed gases is carried out in a uniform cyclone-like droplet separator composed of several nested cylinders. The invention also relates to a method for momentarily bypassing, during a capacity rise, a scrubbing phase that causes pressure loss. As a result, there is obtained a clean and dropless gas that falls below the allowed dust content limits and can thus be either conducted to combustion or discharged in the open air. The invention also relates to an apparatus, a multiphase scrubber, for realizing the method. The invention is particularly suited to be used for scrubbing hot furnace gases from closed reduction furnaces, where said furnace gases contain easily inflammable components.
