Low-pressure desalinization device

Claim 1

A distillation apparatus comprising: (a) a water chamber with an open, submerged end, an open interior and a closed upper portion, the open end being submersible in a water source; (b) a condensation and collection pipe affixed to and extending from the upper portion of the water chamber; (c) means for exhausting air from the water chamber to create low-pressure conditions therein at less than atmospheric pressure to decrease surface tension of water in the water chamber and to thereby facilitate the generation of vapor in the water chamber; (d) means connected in the condensation and collection pipe for condensing vapor generated from the water chamber; (e) collection means comprising a collection trap connected in the condensation and collection pipe for collecting water condensed by the condensation means, the collection means including a level control means; (f) distilled water conveying means for conveying the water from the collection means to a turbine, the distilled water conveying means having an upper end and a lower end, the upper end being connected to the collection means and disposed at approximately the height of the closed upper portion of the water chamber, the lower end of the distilled water conveying means disposed adjacent the turbine, the distilled water conveying means being curved between its upper and lower ends; and (g) the turbine being driven by water flowing from the lower end of the distilled water conveying means.
