Abstract 1,021,573. Gas-scrubbers; spray-producers. AJEM LABORATORIES Inc. Oct. 15, 1962 [Oct. 16, 1961], No. 38938/62. Headings B1R and B2F. In a gas-scrubber a stream of gas enters through an inlet 14 and passes upwardly through a funnel-shaped passage 16 where it is sprayed with spray generated by a rotating cage 24 supplied with liquid by an impeller 62 rotating within a tube 84 with an outwardly flared upper section 92 and with its lower end immersed in the liquid in the bottom of the scrubber, the impeller having a frusto-conical hub 62 with helical blades 68. The pitch of the blades increases upwardly and bends in the lower portions of the blades may be provided to increase the pitch sharply. In a modification the hub of the impeller may be cylindrical and in this case the lower portion of the tube 84 may be downwardly and outwardly flared. The position of the upper section 92 may be adjusted.
IN A GAS SCRUBBING APPARATUS OF THE TYPE HAVING A SCRUBBING CHAMBER, AN INLET DUCT FOR GAS TO BE SCRUBBED, AN OUTLET DUCT FOR SCRUBBED GAS, MEANS FOR CAUSING THE GAS TO FLOW INTO SAID CHAMBER THROUGH THE INLET AND OUT OF SAID CHAMBER THROUGH THE OUTLET, AND MEANS FOR COMPELLING THE FLOW OF GAS TO PASS THROUGH AN ANNULAR SPACE WITHIN THE SCRUBBING CHAMBER, THE COMBINATION THEREWITH OF MEANS LOCATED CENTRALLY OF SAID ANNULAR SPACE AND ADAPTED FOR FORMING AN UPWARDLY DIRECTED OUTWARDLY FLARED STREAM OF LIQUID COMPRISING A CYLINDRICAL SHROUD OUTWARDLY FLARED NEAR ITS TOP DEFINING AN UPWARDLY DIRECTED CHANNEL FOR SAID STREAM, AN OUTER ROTOR SUBSTANTIALLY COAXIAL WITH AND ABOVE SAID SHROUD AND SURROUNDING SAID STREAM, SAID OUTER ROTOR HAVING SPACED LONGITUDINAL FACES WHICH COLLIDE WITH LIQUID OF SAID STREAM DURING ROTATION SPATTERING IT INTO DROPLETS AND THROWING OUTWARD BY CENTRIFUGAL FORCE THE DROPLETS THUS FORMED, MEANS FOR ROTATING SAID ROTOR AT HIGH VELOCITY, AN INNER ROTOR WITHIN SAID SHROUD COMPRISING A HUB BLOCKING THE CENTER OF SAID CHANNEL AND DEFINING WITH SAID SHROUD AN ANNULAR CHANNEL FOR SAID LIQUID, SCREW IMPELLER BLADES ON
