ABSTRACT:
This invention utilizes distillation to purify water but instead of the usual application of heat to boil the water and then condense it, heat is applied to a relatively small quantity of water which is confined until it is superheated. When the pressure reaches a pre-set level the water is released allowing sudden expansion to a vapor to create a high velocity directed through a venturi to suck water from the main body of water lifting it into an expansion chamber located at the elevation above the main body of water equaling the maximum lift by suction. The vapor is then led through a heat exchanger where it will circulate until it is condensed. Some of the condensate will replenish the water to be heated while the remainder is led around the vacuum chamber to heat the water therein and then to storage. In-as-much as a vacuum system is used to lift the water, the lower end of the vacuum chamber may be left open to the source of the water, which may be the ocean, and the concentrated pollutants will disburse back to the source and keep the fouling of the inside of the vacuum system to a minimum. Flow resistance is utilized to aid in separating the higher concentration of pollutants in the vacuum chamber from the polluted water freshly arriving.
