  • Patent number: 4010080
    Abstract: A solar powered distilling device, and more particularly, a device wherein a plurality of convex lenses concentrate the heat energy of sunlight to heat and vaporize a quantity of water, said water vapor rising from a vaporization chamber to a cooling chamber by virtue of spaces provided between troughs located there between, the water vapor is cooled by virtue of the circulating air in an air cooling chamber condensing the vapor into water droplets; said droplets being collected in said collection troughs provided for this purpose.

  • Patent number: 3980526
    Abstract: A water distillation unit is disclosed herein. The unit preferably comprises an upper boiler container and a lower condensation container which are rigidly maintained in spaced apart relationship by a molded coupling member containing a plurality of water passageways and fittings. The coupling member is integral with the condensation container and is removably and threadably attached to the upper boiler container so that same may be easily removed when desired for cleaning. The boiler container receives raw liquid which is vaporized by an interiorly disposed heater element. The condensation container houses a condenser tube which receives steam from the boiler container and conducts distillate exteriorly of the apparatus. To improve thermal efficiency the condenser tube is cooled by raw liquid which is routed through the condensing container.

  • Patent number: 3935077
    Abstract: An automatic water distiller has an insulated evaporator to which water is supplied after being preheated by cooling the steam, which is produced by the evaporator, in a condensing chamber with which the water is in heat exchange relation. Air also flows in heat exchange relation with the condensing chamber to aid in condensing the steam. A storage chamber is disposed above the evaporator and beneath the condensing chamber to receive the condensed steam and the air, which flows over the condensing chamber to cool the steam therein, is first passed in heat exchange relation with the distilled water in the storage chamber. The vapors in the condensing chamber are vented to the chamber in which the water is in heat exchange relation with the condensing chamber.
