SMOKE FILTER Russian patent published in 1994 - IPC

FIELD: purification works. SUBSTANCE: smoke filter includes multi-storeyed building of cylindrical form, for instance. Electric discharge pumps are built in into its floors, outlet chamber is provided with system of tangential nozzles-slots, all floor contact chambers are interconnected in series and are coupled to source of water supply with the aid of pipe-line and pump. With switching on of electric discharge pumps the latter form high pressure over shock wave fronts around dischargers and in chambers which ensures active coagulation of chock waves around dischargers and in chambers and precipitation of solid particles and gas impurities in system of hydraulic ash removal providing for complete cleaning of stack gases. System of tangential nozzles-slots forms torque of cleaned discharged gases providing for increase of altitude of their dispersal which enhances efficiency of filter. EFFECT: enhanced efficiency of filter. 5 dwg
