VORTEX SCRUBBER Russian patent published in 2005 - IPC

FIELD: heat-and-mass exchange apparatus; chemical and food-processing industries; metallurgy.

SUBSTANCE: proposed scrubber is used for wet cleaning of gases from solid, liquid and gaseous admixtures as well as for cooling and condensation of vapor, conducting chemical reactions in the gas-liquid-solid systems. Proposed scrubber includes housing 1 equipped with cylindrical and taper contraction tube 2, neck 3 and diffuser 4, nozzle 5 mounted coaxially in housing and provided with branch pipe 11 for admitting the dust-and-gas flow and L-shaped supply branch pipes 7 which are turnable around their axes; it is also provided with gas-separating reservoir 8 equipped with branch pipes for discharge of cleaned gas and water with entrapped particles; supply branch pipes 7 are connected to liquid absorbent delivery system; nozzle 5 is axially movable relative to housing 1. Dust-concentration sensor 12 built in dust-and-gas flow inlet branch pipe is connected with controller 13 connected in its turn to actuating mechanism 14 of adjusting valve 15 mounted between liquid absorbent delivery system and supply branch pipes 7. Branch pipe 9 used for discharge of liquid containing entrapped particles is mounted tangentially relative to gas separating reservoir 8. Cleaned gas is evacuated from apparatus through branch pipe 10. Nozzle 5 is mounted hermetically in housing 1 by means of seal 6. Proposed scrubber makes it possible to conduct violent reactions in liquid-solid systems and in gas-liquid-solid systems without preliminary cleaning in other apparatus and to exclude use of drip pans; it also provides for control of force (centrifugal) field in scrubber depending on parameters of dust-and-gas flow.

EFFECT: enhanced efficiency of scrubbing; reduced length of apparatus with no change in productivity.
