GAS SCRUBBING APPARATUS Russian patent published in 1994 - IPC

FIELD: purification of gases of steam power plants from fly ash. SUBSTANCE: emulsification conditions are created in tubular headpieces of apparatus generated as a result of engagement of twisted flow of impured gas with sprinkling water fed to tubed in bulk in gas counterflow. Flow twisting device is in the form of chamber combining four tubes and looking in plan like as rosette of four semicylinders with four symmetrically positioned holes for tubes. On opposite side surfaced of chamber in places of joint of semicylinders there are two slit holes to receive two counterflows generating four stable vortexes with collision of flows. EFFECT: enhanced operating reliability. 2 cl, 3 dwg
