WET TYPE DUST COLLECTOR FOR EXHAUST FROM TREATMENT DEVICE FOR GRAIN CROPS

摘要

PROBLEM TO BE SOLVED: To obtain an excellent dust collection effect by providing an exhaust introducing part constituted by connecting a diffuser to a scrubber on the ceiling of a dust collection chamber, a cleaned gas discharging part provided with a mist separator at one of the side walls and a sludge discharging conveyor at the bottom of the lower liquid-stored part. SOLUTION: The follow-up scrubber 4 is provided on the ceiling 3 of the dust collection chamber 2 and the mist separator 5 is provided at one side wall to form an exhaust outlet 6. The exhaust introducing part 25 is fixed so that the opened area of a throat part 7 of the scrubber 4 is maximized and water streams for removing dust are sprayed in a mist state from a spray nozzle 9 of the scrubber 4. The mist sprayed in a mist state is moved to the outlet 6 together with air, separated/removed at the separator 5 and flowed out from the outlet 6. The precipitates such as sludge separated in the liquid- stored part 14 are scraped by a scraping blade 22 of a scraper 15 and discharged from a precipitate discharging port to a precipitate carrying container.
