    • Devices and methods for producing purified water. The device includes a reverse osmosis subsystem, a dehumidification subsystem and a purified water storage tank fluidly coupled to the subsystems such that purified water produced by each can be locally stored. A vehicular platform, such as a ship, can be used to locate the device adjacent a supply of saline water and humid air. A saline water inlet, membrane and purified water outlet cooperate in the reverse osmosis subsystem to allow preferential passage of water relative to salt in a saline water supply, while the dehumidification subsystem includes a heat exchanger that extracts moisture from the ambient humid air. Purified water produced by each of the subsystems can be used as a potable water source. When used in conjunction with a ship, part or all of the reverse osmosis subsystem can be submersed to a depth sufficient to generate a hydrostatic pressure that is in turn sufficient to passively operate the reverse osmosis membrane such that additional pressurizing equipment, such as a pump, is not needed. Furthermore, the temperature of the water purified by the reverse osmosis subsystem may be low enough to be used as a condensing agent for the ambient humid air passing through the dehumidification subsystem.
    • 用于生产纯净水的装置和方法。 该装置包括反渗透子系统,除湿子系统和与子系统流体耦合的净化储水箱,使得由每个子系统产生的净化水可以被局部存储。 诸如船的车辆平台可用于将设备定位在邻近盐水和潮湿空气的供应处。 盐水入口,隔膜和纯净水出口在反渗透子系统中配合,以允许在盐水供应源中相对于盐优先通过水,而除湿子系统包括从周围潮湿空气中提取水分的热交换器。 由每个子系统产生的净化水可以用作饮用水源。 当与船舶一起使用时,部分或全部反渗透子系统可以浸没到足以产生静水压力的深度,这进一步足以被动地操作反渗透膜,使得附加的加压设备,例如泵 ,不需要。 此外,由反渗透子系统净化的水的温度可能低到足以用作通过除湿子系统的环境潮湿空气的冷凝剂。

    • 1,031,141. Condensing vapours and melting ice; distillation of water. DESALINATION PLANTS (DEVELOPERS OF ZARCHIN PROCESS) Ltd. April 6, 1964 [April 29, 1963], No.14103/64. Heading B1B. An apparatus for condensing vapour and melting ice in a vacuum chamber 102 and which is particularly applicable to the production of pure water by distillation comprises a rotatable, hollow, frusto-conical ice receiver 116,a drive 124 for rotating the receiver, an inlet 156 through which ice is introduced into the chamber, an opening 102 through which vapour is supplied into contact with the ice to condense the vapour and melt the ice, and in outlet 164 for removing the condensate and the melted ice from the chamber. The receiver 116 is supported by a sleeve 126 which is carried by the drive 124 and has a plurality of T-shaped supports 128 welded thereto, the power portion of the receiver 116 also being secured to the supports. Further support members 132 are also employed. To delay the movement of ice along the inclined surface of the receiver movable and pivotal plates 180 which have a plurality of perforations therein to permit vapour to contact the ice are suspended from horizontal members 182,184 and 186. The condensate flows along the inclined surface and through apertures 119 of a ring 121 which is mounted on a frusto conical support which provides drain means for the condensate and then passes through apertures 160 in the supports 128 to the outlet 164. Air is removed from the chamber by passing through a central opening 179 in the member 122 and flowing, as shown by arrows, to outlet 174. In a desalination apparatus (Fig. 1, not shown) sea water is introduced into a low pressure chamber 20 where it flash evaporates so producing vapour and forming pure ice. The vapour then passes to a compressor 54 and is delivered radially outwardly into the condensing chamber 102 through an annular outlet 58 by means of a rotating impellor 72. The brine with ice crystals therein is delivered to a separator washer where the ice is separated and washed free of salt and fed to inlet 156 of the condensing chamber.
