FIELD: mining industry, particularly to provide dust control in different processes by ejecting dust-laden air and entraining dust particles with liquid spray cone inside device and by separating the formed sludge. ^ SUBSTANCE: device has body with inlet and outlet orifices, injector nozzle, sludge trap and sludge removal pipe. Spray nozzles communicated with sludge trap through orifices of the body are arranged along inlet orifice perimeter. Sludge trap has floating valve arranged in bottom sludge trap part and installed in sludge removal pipe. Device also has dust catching sheets arranged between inlet and outlet orifices and defining working space for spray cone generated by injector nozzle shaped as expanding diffuser, which provides free spray cone penetration into sludge trap and air suction into inlet orifice. Dust catching sheets located near inlet orifice are inclined from body periphery towards spray cone axis and dust catching sheets arranged near outlet orifice are inclined from spray cone axis to body periphery. ^ EFFECT: increased capacity and efficiency, possibility of rational wetting liquid utilization. ^ 2 dwg |
