Abstract

Sea water is desalinated in multi-stage flash evaporator comprising four coaxial columns 14, 16, 18, 20 which form an axial chamber 13 and three annular chambers 15, 17, 19, arranged at progressively increasing height, each chamber communicating with the adjacent chamber through lower openings 30 and upper openings 26, 28. The arrangement is such that, when the evaporator is in operation, there is an automatic drop in pressure from chamber 13 to chamber 20. The sea water to be distilled, after flowing through heat exchanger 33 and heater 32, is introduced into the lower section of chamber 13. Cold distilled water is supplied to the upper section of chamber 20. The sea water rises successively through the lower sections of chambers 13, 15, 17, 19 and distilled water flows successively through the upper sections of the chambers in the reverse direction. Flash evaporation of some of the sea water takes place in the lower section of each chamber and the vapours are condensed by a rain of distilled water 24, distributed by perforated plate 27, in the upper section of the chamber. The droplets of distilled water are received in an annular collector 23 in each chamber, and the liquid then flows through openings 28 into the condenser of the next lower chamber. The required difference in pressure between the chambers is established due to the depth of distilled water above the perforated plate 27 in each chamber. Residual brine is withdrawn from chamber 19 through pipe 34, and is in part recirculated with fresh feed to heater 32 and chamber 13. Warm distilled water is withdrawn from the collector in chamber 13, and is cooled by conducting it through heat exchanger 33. Part of the cool distilled water is withdrawn from the system as product, and the remainder is recirculated to the condenser of chamber 20.
