FIELD: gas cleaning and/or cooling. SUBSTANCE: thin-filmed liquid is supplied in the form essentially of umbrella-shaped shells, or of linear curtain in regular spacing and distributed in two or more phases perpendicular to direction of main flow of gas. Thin-filmed liquid is supplied so that gas is distributed due to pulse action of liquid exerted on gas in direction square to gas main flow. Orthogonal distance between adjacent planes to which thin-filmed liquid is supplied is regulated so that there is no significant equalizing of gas flow between planes. Liquid in adjacent planes is supplied in direct flow and in counterflow to the gas main flow. EFFECT: higher efficiency. 10 cl, 11 dwg
