Beschreibung
Zusammenfassung:	FIELD: metallurgy; methods of preparation of process gases containing high-ohmic dust for cleaning in electrical filters. SUBSTANCE: proposed method includes preliminary treatment of process gases by humidification and cooling at temperature of dust-laden process gases before electrical filter from 30 to 150 C; cleaning gases from dust is performed at temperature exceeding dew point by 5-10 C; as temperature of gases increases, intensity of moisture saturation as compared with initial magnitude is regulated in synchronism with dynamics of moisture content at dew point exceeded by at least 4-7 C at each rise of temperature by 10 C ensuring rise of temperature above controllable dew point. EFFECT: enhanced efficiency of electrical deposition of dust. 2 cl, 2 dwg
