Abstract

1,120,938. Evaporators, flash type; desalina tion of sea water. WESTINGHOUSE ELECTRIC CORP. 23 June, 1967 [10 Aug., 1966], No. 29039/67. Heading BIB. In an evaporator comprising a series of flash chambers A, B, C communicating with condenser spaces 27, 26, 25 respectively, maintained at progressively lower pressures by ejector pump 50, the condensate collected in trays 33, 32, 31 is cooled by passing it into chamber 75 which is maintained at a lower pressure than chamber C by ejector pump 82 so that a portion of the condensate flashes into vapour which condenses on cooling tubes 80. The cooled condensate is withdrawn through line 88. Ejector 82 exhausts into the conduit 51 connecting chamber C to ejector 50 which discharges air from the system. The apparatus may be used for the desalination of sea water which is pumped in through tubes 80 and 45. A small portion of the sea water is then returned to the sea through conduit 56, and the major portion flows through tubes 46, 47 to heater 60. The heated feed then flows through flash chambers A, B, C. Part of the brine withdrawn from chamber C is discharged from the system, and the remainder is recirculated to tubes 46, 47 through line 72.
