Abstract

792,588. Centrifugal separators. RESEARCH-COTTRELL. Inc. May 3, 1956 [July 29, 1955], No. 13695/56. Class 23 [Also in Group XL(a)] In a combined electrostatic and mechanical gas cleaning apparatus, tubular collecting electrodes 24, which are supported in a header plate 22, are positioned vertically above separator tubes 44 supported in a header plate 42. Discharge electrodes 38, having disc-like members which provide a plurality of corona discharge edges, depend from a high tension frame 30. Gas containing suspended particulate material enters the apparatus through the inlet 16 and is then mixed with water particles from spray nozzles 62. The gas and entrained water passes between the lower, narrower portions of the collecting electrodes and the inner surfaces of the separator tubes where it is given a vortical motion by means such as vanes or tangential inlets. The gas is subjected to centrifugal separation within the tubes 44 and a portion of the particulate material leaves the tubes through narrow outlets communicating with hopper means at the lower end of the apparatus. The gas stream then passes up through the collecting electrodes where corona discharge and the high voltage maintained between the discharge electrodes and the collecting electrodes separates the remainder of the material suspended in the gas stream which is precipitated upon the inner surfaces of the collecting electrodes. Flushing liquid from the ponds maintained by conduit means 28 above the plate 22 flushes the precipitated material from the inner surfaces of the collecting electrodes down through the outlets of the separator tubes 44.
