Abstract

1,047,981. Multi-stage flash comparator; distilling sea water. RICHARDSONS, WESTGARTH & CO. Ltd. Oct. 31, 1962 [Nov. 8, 1961], No. 40091/61. Heading B1B. In a flash evaporator, particularly for distilling sea water, comprising a series of stages, each comprising a flash chamber 14 and an associated heater-condenser 12 or 24, wherein the vapour is cpndensed, thus preheating the liquid to be evaporated, the vapour generated in one of the intermediate stages is withdrawn and compressed by a mechanical compressor 33, e.g. rotary compressor or piston compressor, and the compressed vapour, mixed with steam from an external source, is used to heat the brine in heater 20 to the required temperature before it enters the first flash chamber. Fresh cool brine, supplied to the evaporator via pump 28 and line 26,passes through the heatercondensers 24 and then via line 30 into the last flash chamber 14, where it mixes with the concentrated brine leaving the evaporator. Part of this brine mixture is discarded, andthe remainder is pumped to the first stage of the evaporator via line 10, heater-condensers 12,and heater 20. The vapour generated in flash chamber 14 passes into heater-condensers 12 or 24 via lines 13 or 25, and heats either the recirculated brine or the fresh brine. Vapour is withdrawn from heatercondenser 12a, or 24a or vapour receiver 40, via line 36, 38 or 42 respectively,by compressor 33, which is driven by steam turbine 32 receiving high pressure steam from boiler 31. The low pressure exhaust steam from turbine 32 is mixed with the compressed vapour from compressor 33, and the mixture is passed into heater 20 via line 22. The condensate from heater 20 may be removed for boiler feed water via line 21,or supplied to the condensate in receiver 12 of the first stage via line 23. The condensate formed in receivers 12 and 24 is finally removed by pump 16.
