Sea- or lake water desalinator constructed as floating unit, e.g. as a boat

摘要

This unit desalinates sea- or lake water, using an evaporation chamber on or within a float with a solar window. The new arrangement includes a unit (4) in the chamber (2) with a fan on top, extracting air saturated with water vapour. This passes through the evaporation chamber or float base, to a seawater-cooled condenser (6) with lines (7) returning drier air back to the chamber. Desalinated water falls into a collector (8) following the condenser, where devices (9) convey it to a vessel (10) above the water level. Through the base of the evaporation chamber (2) there is a further unit (11) in the form of a heat exchanger, which both returns and abstracts salt water from the source.
