FIELD: manufacturing technology.
SUBSTANCE: invention relates to a dust collection technique. Dust collection unit consists of pre-filter and thin filter, interconnected by duct, so that the outlet of pre-filter is connected to the input of thin, prefilter comprises body consisting of cylindrical and conical parts, peripheral gas flow inlet and axial outlet of purified gas located in its upper part, is provided with acoustic column, which in its lower part is connected to axial outlet branch pipe of purified gas and contains conical baffle, installed by its large base in lower base of the column, and the cavity formed by surfaces of baffle plate and column is connected by bypass tap with peripheral gas flow inlet, and in upper part of acoustic column there is outlet branch of purified gas and oscillation generator connected to control unit, and on cylindrical part of the body a ring is rigidly fixed connected by means of brackets to the base or pedestal, and remaining cylindrical part of the body with conical part is attached to ring by additional ring and elastic element, while the vibrator with control unit is located on the ring, rigidly connected to conical part of cyclone and to base through elastic element.
EFFECT: increasing efficiency of dust collection.
