Abstract
A thermal desalination system connected to a heat source, such as a power plant that generates waste heat, that produces a heated liquid. The heated liquid is routed to a heat exchanger and/or a desalination device before being returned to the heat source. When present, the heat exchanger preheats water for subsequent purification by distillation, thereby producing potable water.
Claims20
A thermal desalination system comprising:
- a heat source that heats a substance to produce a heated liquid;
- a fluid path for transferring the heated liquid to a thermal desalination tower configured to receive the heated liquid;
- a return path for transferring the heated liquid from the thermal desalination tower to the heat source;
- a raw water source with raw water;
- a raw water line that transfers the raw water from the raw water source to the thermal desalination tower, the thermal desalination tower configured to distill the raw water using heat from the heated liquid, thereby producing potable water;
- a potable water tank for storing the potable water;
- and
- the thermal desalination tower comprising a lower distillation portion comprising:
- a hot liquid jacket with a double-walled chamber that is disposed about a hollow cavity, the raw water being transferred to the hollow cavity through a raw water input port, the heated liquid entering the double-walled chamber through a fluid input and exiting through a fluid output, thereby heating the raw water in the hollow cavity to produce vaporized water;
- an interior surface for condensing the vaporized water, thereby producing distilled water;
- and
- at least one gutter disposed within the thermal desalination tower such that the at least one gutter receives the distilled water from the interior surface.
