Patent ID: 7832714

Claim:
A desalination system comprising: a desalination system evaporator comprising: a first vessel having an interior adapted to hold a liquid; a tube disposed within the first vessel and adapted to transport a gas into the interior of the first vessel; a weir disposed within the first vessel adjacent the tube in a manner that defines a confined volume between the tube and the weir; a vapor pipe adapted to transport exhaust vapor from the interior of the first vessel; and a liquid inlet adapted to supply a liquid to the interior of the first vessel; wherein the weir includes a first weir end and a second weir end and is disposed within the vessel to define a first circulation gap between the first weir end and a first wall of the first vessel and to define a second circulation gap between the second weir end and a second wall of the first vessel which enables liquid within the first vessel to flow through the first and second circulation gaps when gas is introduced into the first vessel from the tube; and a condensing unit comprising: a second vessel having an inlet and an outlet for supplying a cooling fluid; a vapor pipe passing through the second vessel and at least partially surrounded by the cooling fluid within the second vessel; a liquid collection and exit port for removing condensed liquid from the second vessel.
