FIELD: gas cleaners with movable nozzles for cleaning gases from finely-dispersed particles in various industries. SUBSTANCE: proposed device is divided into sections; each section consists of hollow perforated cylinder located on perforated horizontal partition; upper portion of section of hollow cylinder is made in form of circular shutter grate as far as horizontal partition. Horizontal perforated partitions used for distribution of gas and limitation of height of fluidized layer have different open areas. Sprinkling of sections is effected due to delivery of liquid under pressure through perforations of hollow cylinder; removal of liquid from sections is effected due to fall through perforated partitions and through circular shutter grate. EFFECT: enhanced efficiency of contact of phase due to stability of fluidized layer and organization of sprinkling of each section with fresh liquid. 5 cl, 2 dwg
