Claims
- 1. In a power generating system using concentration energy in a concentrated brine solution as an energy source, a brine concentrator comprising:
- an air flow heat exchanger for admitting hot dry air at one end and for exhausting cool humid air at another end;
- a warm water loop contacting said air flow heat exchanger for extracting heat from said air flow to heat a circulating water flow;
- a cool water loop contacting said air flow heat exchanger for adding energy to said air flow;
- a water spray in said air flow heat exchanger intermediate said warm water loop and said cool water loop as an energy exchange medium between said cool water loop and said hot dry air;
- a brine concentrating unit receiving relatively dilute brine, wherein said relatively dilute brine is heated by said warm water loop to evaporate water from said brine solution to form a more concentrated brine solution and said evaporated water is condensed by said cool water loop.
- 2. A brine concentrator according to claim 1, wherein said brine concentrating unit includes a plurality of serially connected stages to progressively concentrate said brine solution.
