Abstract
A method of and apparatus for purifying gases, especially industrial waste ases, according to which a solid surface layer adapted to adsorb impurifications is formed on rotatable discs of which successive portions during the rotation of the discs temporarily protrude from a liquid containing container. This layer, when being contacted by the gas to be purified, adsorbs the impurifications and harmful substances of the gas. The exhausted portion of the surface layer is replaced successively by a new surface layer portion formed by wetting the disc portions when the latter pass through the liquid in the container.
