Abstract

<PICT:0819025/III/1> In a method for obtaining fresh water from sea water or other raw water by passing it through an evaporator 7 under reduced pressure wherein water is evaporated at a temperature not exceeding 48 DEG C., and condensing the vapours in condenser 29, the formation of scale in the evaporator is obviated by using an hourly supply rate of raw water to the evaporator equalling 10 to 20 times the water-containing volume of the evaporator while maintaining a salt concentration in the water in the evaporator not exceeding twice the original salt concentration in the raw water. The heating is effected in a large number, e.g. 500 to 800, narrow vertical tubes 15, and the evaporator is also provided with a wide centre tube 14, the dimensions being such that the amount of water in the narrow tubes constitutes at least one third, preferably 48 to 60 per cent, of the total quantity of water in the evaporator. Tube 14 may have a diameter of 200 to 300 mm., while the diameter of tubes 15 may be 16.5 mm. Tubes at may be heated by circulating the water from the cooling jacket of a marine diesel engine around them, this water being introduced at a temperature of about 65 DEG through line 9, and removed through line 12. Reduced pressure is maintained in the plant by means of pump 49 which is connected to the condenser by line 47. Sea water is circulated through the cooling-tubes 30 of the condenser via lines 31 and 33, a valve 34a being inserted between line 33 and the feed-line 1 to the evaporator. The preheated sea water is fed into the evaporator through lines 1 and 6, and the concentrated water is withdrawn through lines 16 and 19. A constant water-level is maintained in the evaporator by float-valve 2. Line 19 is connected to conductivity meter 61 and relay 62. The concentration of the effluent water is controlled by meter 61 which, when it records a predetermined concentration, releases an alarm (not shown), or reduces the flow of hot water in line 9 by means of valve 63, or increases the flow of sea water through the evaporator by means of valve 64. The vapours, formed in the evaporator, flow into cyclone 27, and then down tube 28 into the condenser. Distilled water is withdrawn from the condenser via line 36 and pump 38.
