Abstract
Systems and methods for desalting seawater by means of distillation are disclosed. Warm air is fed into the bottom of a natural draft tower. The warm air passes through seawater in an exchange means to increase the water content of the air. The moisture-laden air then rises and is drawn through a condensing means. The condensing means is cooled by cold water drawn from deep ocean depths. Desalted seawater is
Claims17
A natural draft tower having two contiguous open chambers for the desalination of seawater comprising:
- (a) solar heating means for heating incoming air,
- (b) first chamber having air-liquid exchange means and open to receive said heated incoming air to produce moisture-laden air,
- (c) second chamber open and contiguous to said first chamber having condensing means for cooling said moisture-laden air, and
- (d) tubular means connected to condensing means and extending to an ocean depth where ocean water is less than 7° C.

A method for desalting seawater in a natural draft tower having two contiguous-chambers comprising:
- (a) feeding warm seawater to water evaporation means in first chamber,
- (b) warming ambient air in solar heating means,
- (c) passing said warm air through said water evaporation means in said first chamber to produce moisture-laden air,
- (d) passing deep-ocean water of less than 7° C. through condensing means in second contiguous chamber,
- (e) channeling said moisture-laden air through said condensing means to produce fresh water, and
- (f) collecting said fresh water.
