Distilling apparatus

Distilling apparatus comprising, in combination:

• input apparatus including a boiling chamber and means for supplying raw liquid to said boiling chamber at a predetermined level;
• a closed condensation chamber above said predetermined level connected to the top of said boiling chamber and communicating therewith so as to receive therefrom only vapor from said raw liquid;
• output apparatus including a liquid collection container below said condensation chamber and communicating therewith to receive liquid from said condensation chamber, and liquid circulating means moving liquid from said container, cooling the liquid, discharging it within said condensation chamber, and allowing the liquid to drain from said condensation chamber with liquid condensed from said raw liquid vapor so as to entrain bubbles of gas therein and provide a pressure head in said output apparatus as said liquids drain to said container, wherein said condensation chamber is cooled by liquid from said container and a subambient pressure is created within said boiling and condensation chambers;
• circulation and vacuum creation augmentation pump means interposed in said output apparatus to further facilitate creation of said subambient pressure in said boiling and condensation chambers;
• a second closed chamber interposed in said output apparatus below said condensation chamber;
• a plurality of conduits extending downward from said condensation chamber into said second closed chamber;
• and
• an inlet conduit from said pump means extending into said second closed chamber, and having an inlet port in said second closed chamber,
• the tops of said plurality of conduits being level with the bottom of said condensation chamber,
• and the bottoms of said plurality of conduits being below said inlet port of said inlet conduit in said second closed chamber.
