Abstract

1,200,221. Purification of water. CURZON DOBELL. 1 Aug., 1967, No.35178/67. Heading B1B. [Also in Divisions F3 and F4] Potable water is obtained from sea water (or other non-potable water) in reservoir 20 by passing a stream of atmospheric air over briaded-cotton wick plates 22, which are saturated with the sea water, so that the air takes up water-vapour, drawing the moistened air by if an 25 in section 17 where the air is cooled by coils 32, 33 and water-vapour condenses. The condensate .(i.e. potable water) is withdrawn from section 17 through pipe 41 by pump 42, and is received in tank 44. Partially unsaturated atmospheric air enters the apparatus through inlet 19 and is heated in section 15 before it passes over wick plates 22. The air may be heated by the sun, in which case baffle plates 30 are painted black. As shown, the apparatus will float in the sea at level 39; and rudder 45 adjusts its position so that inlet 19 is constantly facing the wind. Air is discharged from the apparatus through outlet 46. Coils 32, 33 may be cooled by feed water which then passes through pipe 36 to reservoir 20. A land-based apparatus is described wherein the air to be heated flows up an annular passage, the external wall of which has annular fins to absorb solar heat.
