GAS CLEANING DEVICE Russian patent published in 1999 - IPC

FIELD: cleaning of gas flows from solid particles and liquid admixtures; oil, chemical, gas, food-processing industries and power engineering. SUBSTANCE: gas cleaning device has first and second sections connected in series whose working members combined in single detachable unit are built in vertical cylindrical housing blanked off at the top. This unit is provided with partitions which divide inter-tube cavities of first and second sections downward, collector with lateral discharge of cleaned gas and common bin for receiving entrapped admixtures which is located in lower portion of housing. First section with lateral inlet of cleaned gas is made in form of inertial gravitational phase separator and second section is made in form of straight-flow centrifugal separator with gas transfer passage made in form of injector whose injecting gas inlet is brought in communication with upper portion of cavity first of section and inlet of gas being injected is communicated with upper portion of cavity of second section. Mixing tube of injector is located along inner lateral wall of housing opposite to inlet of gas being cleaned. Besides that, radial fins embracing the working members of device are located in cavity of second section tightly to inner lateral wall of housing and in parallel with its generatrix. EFFECT: extended range of loads and increased service life of device. 2 cl, 2 dwg
