GAS SCRUBBING UNIT Russian patent published in 2004 - IPC

FIELD: cleaning gas flows from solid and liquid admixtures; oil, chemical, gas and food-processing industries; power engineering. SUBSTANCE: proposed unit includes first and second sections connected in series with working members built in vertical cylindrical housing which is blanked off at the top through partitions dividing inter- tube spaces of first and second seconds; scrubbing unit includes also side branch pipe for escape of cleaned gas and common bin for receiving admixtures; first section provided with side inlet for 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 bypass passage. Novelty of invention consists in form of bypass passage made as axial-flow ejector whose ejecting gas inlet is combined with outlet of gas to be cleaned from nozzle of sharply bent branch pipe connected to side inlet; ejecting gas inlet is communicated with lower portion of first section through intake pipe whose lower end is open to bin and upper end is open to cavity of first section in such way that partitions are bounded with wall which is perpendicular to coaxial inlet and outlet on one side and by part of vertical cylindrical housing on other side; on side of second section wall has cut directed to cavity of intake pipe. EFFECT: enhanced operational reliability; extended range of loads at retained efficiency of process. 2 cl, 3 dwg
