Abstract
A distillation system is provided having an evaporation conduit and a condensing conduit connected by a transfer system for transferring distillate vapour from the evaporation conduit to the condensing conduit to condense the distillate. The evaporation and condensing conduits operate under vacuum pressure. A distillate conduit communicates with the condensing conduit for dispensing condensed distillate therefrom. An air passage in heat exchanging relationship with the distillate conduit produces an upward heated flow which is directed to a turbine to extract usable energy therefrom. The transfer system comprise a rotor having port therein which extend from the evaporation conduit to the condensing conduit with
Claims20
A distillation system comprising:
- an evaporation conduit;
- an intake supply conduit in communication between a source of solution and the evaporation conduit at the top end of the intake supply conduit;
- an intake return conduit in communication between the evaporation conduit at a top end of the intake return conduit and a return sump;
- a condensing conduit;
- a transfer system connecting the evaporation conduit and the condensing conduit and which is arranged to transfer distillate vapor from the evaporation conduit to the condensing conduit to condense the distillate vapor in the condensing conduit;
- a distillate conduit in communication with the condensing conduit so as to be arranged to collect condensed distillate therein;
- a vacuum pump connected to at least one of the evaporation conduit and the condensing conduit so as to be arranged to evacuate air from the evaporation and condensing conduits;
- a heat exchanger passage in heat exchanging relationship with the distillate conduit so as to be arranged to produce a heated flow of fluid therein;
- and
- a turbine in communication with the heat exchanger passage so as to be arranged to extract usable power from the heated flow of fluid in the heat exchanger passage.

- an evaporation conduit;
- an intake supply conduit in communication between a source of solution and the evaporation conduit at the top end of the intake supply conduit;
- an intake return conduit in communication between the evaporation conduit at a top end of the intake return conduit and a return sump;
- a condensing conduit;
- a transfer system connecting the evaporation conduit and the condensing conduit and which is arranged to transfer distillate vapor from the evaporation conduit to the condensing conduit to condense the distillate vapor in the condensing conduit;
- a distillate conduit in communication with the condensing conduit so as to be arranged to collect condensed distillate therein;
- and
- a vacuum pump connected to at least one of the evaporation conduit and the condensing conduit so as to be arranged to evacuate air from the evaporation and condensing conduits;
- the transfer system further comprising a pump rotor having a first side in communication with, the evaporation conduit, a second side in communication with the condensing conduit, and at least one port communicating between an inlet opening at the first side and an outlet opening at the second side;
- the pump rotor being supported for rotation about a central axis;
- and
- said at least one port being oriented with increasing radial distance from the central axis from the inlet opening to the outlet opening so as to be arranged to transfer fluid from the first side to the second side under centrifugal force when rotated.
