FIELD: gas scrubbing from impurities; may be used in any industry where cleaning of gas flows is required, in particular, in chemical and food industry. SUBSTANCE: plant consists of body in the form of cylinder and truncated cone coaxial with body; inlet pipe for supply of dust-laden gas; injector and outlet pipe for discharge of cleaned gas. Installed in body side part is branch pipe for regulation of liquid level and suction branch pipe for supply of liquid to injector. Body lower part is provided with gate. Branch pipe for discharge of cleaned gas is made in the form of hollow cylinder with lower conical part and is provided with drip pan and located in body upper part. Injector is a hollow tube consisting of cylindrical part, diffuser and contraction. Connected to injector are branch pipe for liquid supply and branch pipe for supply of dust-laden gas. Ratio of injector outlet diameter to diameter of outlet pipe for discharge of cleaned gas equals to 0.5-0.7 and ratio of distance from the level of cleaning liquid to outlet pipe for cleaned gas to its diameter is 0.3-0.5. EFFECT: higher efficiency. 1 dwg
