DUST COLLECTION SEPARATING APPARATUS FOR IMPROVING STRAIGHTNESS OF STREAM OF POLLUTED AIR BY FOG DEVICE, SPIRAL STRUCTURE AND AIR CURTAIN AND IMPROVING DUST COLLECTION EFFICIENCY EVEN AT LARGE WORKPLACE BY PURIFIER AND BLOWERS

摘要

PURPOSE: To provide a fog mixed air curtain type dust collection separation apparatus for improving straightness of polluted air sent to a dust collector from blowers and preventing contamination of components of the blowers such as impeller, thereby improving durability thereof while improving straightness and dust collection efficiency of the polluted air. CONSTITUTION: In an ordinary wet dust collection apparatus for precipitating dust along with falling water and exhausting purified air from polluted air forcibly sucked to purify dust of a workplace, the fog mixed air curtain type dust collection separation apparatus comprises a blower(100) comprising an impeller(120) for forcibly sucking polluted air containing dust, a spiral structure formed on the inner circumferential surface of a duct in which the impeller is installed to form an air stream, a fog device installed on an outer circumferential part of the exit of the duct such that fog is included in the air stream, and a blowing pipe for dividing a blowing air produced by the impeller so that an air curtain is formed around the air stream; and a dust collector(200) comprising a suction duct(210) for sucking the air stream formed in the blower, and nozzles(220) installed in a rear upper part of the suction duct from which water is sprayed to precipitate dust contained in the air stream into a catchment tank(230) and exhaust purified air to the outside of the workplace.
