FIELD: process engineering.
SUBSTANCE: invention relates to industrial grinder waste air cleaners. Proposed plant comprises wet dust separation unit (18) to bring off air with contaminants in contact with flush fluid. Note here that said unit (18) comprises Venturi scrubber with several Venturi stages (14, 16) connected in series along off air flow. Besides, is includes pressure flotation unit (34) and device (26) to force waste flush fluid from wet dust separator (18) to pressure flotation unit (34).
EFFECT: higher degree of separation of contaminants.
