Abstract

983,212. Distillation of water. COW & GATE Ltd. Jan. 3, 1963 [Jan. 3, 1962], No. 295/62. Heading B1B. Fresh water is obtained from an aqueous salt solution, e.g. sea water, by supplying the solution to a series of annular trays 23, Fig. 1, or to a series of annular discs 50, Fig. 2, made of porous material, while hot air is passed over the trays or discs whereby water is evaporated from the solution, and leading the moistureladen air into contact with a surface, which is cooled by some of the salt solution, so that the moisture-laden air is cooled and the watervapour condensed to yield the required fresh water. In Fig. 1, the salt solution is introduced into tank 26 through pipe 27. Some of the solution flows through pipes 30 and 33 on to plate 34 which distributes the solution on to the top tray 23, from which it drips down through holes 24 on to the next tray. Some of the solution in tank 26 overflows through pipe 28 into jacket 15, where it functions as cooling- liquid for the condenser-surface 11. Air is introduced into the apparatus through tube 20; the air is heated by heat-exchangers 18, mounted in duct 13, and the hot air flows up over the solution which it is flowing down from tray to tray. Water-vapour is condensed out of the air on the bottom of tank 26 and on the inner wall of tube 11; and the distilled water, which collects in vessel 17, is withdrawn through pipe 42. Concentrated salt solution collects in vessel 39, and is drained off through pipe 40. The cooled air is recirculated to the heat-exchangers 18 through openings 21. The heat-exchangers may consist of an expansion chamber in the exhaust system of an internal combustion engine. A fan may be used to increase the circulation of the air. The salt solution may be continuously circulated through jacket 15. Cooling may also be assisted by the provision of gilled tubes or fins on the inner surface of tube 11. In Fig. 2, the porous discs 50 are mounted on pipes 51; and there are small holes 53 drilled in each pipe 51 to form communicating passages to the porous discs. The salt solution flows from tray 56 to the pipes 51, and thence to the discs. The discs become saturated with salt solution, and excess solution drips down into tray 54. The discs may be made of felt, supported on wire-mesh.
