Abstract: A device for separating impurities from gases by means of a washing liquid. The device includes three (3) interconnected chambers: a suction chamber, a mixing chamber and a separating chamber, wherein the outer wall of the mixing chamber is the inner wall of the suction chamber and the inner wall of the mixing chamber is the outer wall of the separating chamber. In the upper portion of the mixing chamber there is an inlet which connects the suction and mixing chambers for conveying contaminated gases rising in the suction chamber downwardly into the mixing chamber. In the upper portion of the mixing chamber below the outlet there is mounted a plurality of spray nozzles for downwardly spraying washing liquids which removes impurities in the contaminated gases as they flow downwardly through the mixing chamber. At the bottom of and directly open to the mixing and separating chambers is a liquid collection chamber for collecting used washing liquids and impurities from the gases.
