摘要：1,210,546. Purifying liquids by distillation; desalination of sea water. R. I. ZALLES. 14 May, 1968 [19 May, 1967], No. 22951/68. Heading B1B. Liquid, e.g. sea water or sewage, supplied through valve 38, is heated to about 30‹C above ambient temperature in, heater 33 and is then fed through conduit 35 to a thick, porous layer of fibrous material 11 wherein the liquid forms thin films on the fibres, and air or other gas, supplied by blower 34 to central chamber 30, is directed transversely through the porous layer so that it evaporates some of the liquid flowing over the fibres. The mixture of air and vapours flows to condenser 41; and the condensate, i.e. purified liquid, is withdrawn through conduit 42. In the apparatus shown, the porous layer has a ring-shaped crosssection; it may be made of cotton gauze, and the layer should preferably be at least 0.5 inches thick. The conduit 35, which supplies liquid to the upper part of the porous layer, has a serpentine shape and is perforated with orifices 36. The air may also be preheated in unit 33. Non-evaporated feed liquid is withdrawn from the apparatus through valve 23. In a modified arrangement, the vapours may be condensed on the inner surface of shell 15, around which cooling tubed are disposed. Also described is an apparatus for the desalination of sea water on a large scale, wherein a succession of pans, containing porous material wetted with sea water, moves on rollers through a chamber while air is blown through open-mesh screens in the bottom of the pans. The air may be heated in a series of opaque pipes exposed to the rays of 'the sun. The layer of fibrous material may be replaced by a layer of open-cell foamed or other cellular material.
