FIELD: cleaning of gases (air) from different impurities, for instance, from dust, oil, heavy metals, etc. SUBSTANCE: cleaner has cylindrical-conical body whose conical part is made in the form of changeable nozzle whose height H= (1.5-2.0)Dk, and diameter of discharge opening of nozzle d=(0.6-0.8)Dk, for cleaning gases from heavy metals; d=(0.4-0.6)Dk, for cleaning from dust; d=(0.2-0.3)Dk, for cleaning from water and oil. Diameter of exhaust pipe is D=(0.3-0.6)Dk, while inlet area of tangential branch pipe is F=(0.2-0.4) of the area of diametrical cross-section of body cylindrical part. Dk is diameter of cleaner body. Cleaner may be provided with removable receiving chamber made in the form of sleeve opened from below and accommodating vertical screen covering tangential inlet. EFFECT: higher efficiency. 4 cl, 2 dwgs |
