Abstract:
1. A method of removing salt from an evaporative fluid in a desalination system evaporator having a weir disposed within an evaporator vessel, the weir defining first and second volumes within the evaporator vessel and a gas delivery tube extending into the evaporator vessel into the first volume, comprising: supplying an evaporative fluid to the evaporator vessel at rate sufficient to maintain an evaporative fluid surface level in the evaporator vessel near or above a first end of the weir; providing gas through the gas delivery tube to force the gas through an exit in the gas delivery tube to cause mixing of the gas and the evaporative fluid within the first volume by creating a circular flow of evaporative fluid from the first volume around the first end of the weir into the second volume and from the second volume around a second end of the weir and into the first volume; removing exhaust gases through an exhaust stack in the evaporator vessel; and condensing evaporative fluid vapor contained within the removed exhaust gases.
