mining industry; applicable in dedusting of processes of underground coal mining. SUBSTANCE: device has dust-air ducts with sprinklers and plate moisteners of dust, impeller of axial fan, electric motor and straight-flow cyclone. Impeller is installed coaxially to electric motor shaft at inlet of straight-flow cyclone body whose side wall has longitudinal slot over generating line to tangentially communicate cyclone internal wall with vertical side wall of slime-discharging channel. Dust-air ducts are connected to trapezoidal chamber whose adjacent angles of side walls are equal. EFFECT: simplified design, higher efficiency of air washing and its cleaning from finely dispersed dust fractions. 1 dwg
