AIR CLEANING DEVICE Russian patent published in 2000 - IPC

FIELD: devices for air dedusting; applicable in chemical and gas industry, and in medicinal and household facilities. SUBSTANCE: air cleaning device includes body with funnel-shaped filtering members installed tightly in plate separating body into two parts communicated with each other; pneumatic pulse device for cleaning of filtering members connected with branch pipes; and pressure pickup connected with automatic control system of gas-turbine plant. Installed inside branch pipes are hollow pistons with rods connected with upper part of filtering members for motion over guides in the form of hollow rods located in center of each filtering member. In this case, installed on guides are springs, and guides are connected with system supplying hot air of gas-turbine plant connected with ice detector. The device allows treatment regeneration of filtering members without shutdown of power plant, more efficient regeneration due to increase of amplitude of shaking of filtering cloth and protection of air cleaning device from possible icing, and refusal from traditional heating unit. EFFECT: higher efficiency, reduced specific quantity of metal and aerodynamic resistance of device. 1 dwg
