NON-VOLATILE SOLAR DESALINATION PLANT Russian patent published in 2025 - IPC C02F1/14 F24S10/95 

FIELD: water desalination.

SUBSTANCE: invention relates to power engineering, namely to production of fresh water by thermal distillation of salt water using solar energy. Non-volatile solar desalination plant contains a solar desalination plant, which housing is made in the form of a truncated parallelepiped, and the solar desalting unit upper inclined part has a translucent coating and a liquid heat exchanger made in the form of a closed circuit consisting of a steam generating and a steam condensing parts, partially filled with a low-boiling liquid. Steam-condensing part of liquid-to-liquid heat exchanger is located in lower part of pool with salt water, and steam-generating part of liquid-to-liquid heat exchanger is located in housing of solar collector. Plant also includes a pool with salty water, located in lower part of housing of solar desalter, and solar collector. Under the inner surface of the rear wall of the solar desalter, made of a highly heat-conducting metal, there is a condensate collecting channel with a branch pipe for removing desalinated water, and the outer surface of the rear wall has finning. Enclosing surface is arranged at distance of 50-60 mm from back wall of solar desalter, creating traction effect for additional cooling of back wall of desalter. On the inner surface of the lower part of a salt water pool there is a layer of heat-insulating material, over which there is a layer of light-absorbing material, over which there are solid-state heat-accumulating elements. In solar collector under steam-generating part of low-boiling liquid heat exchanger there located is light-absorbing material layer; under it there located are solid-state heat-accumulating elements, under which there located is heat-insulating material layer. Closed circuit of liquid heat exchanger is partially filled with low-boiling fluid and is made of high heat-conducting metal tube.

EFFECT: invention provides increased efficiency of the plant by increasing the temperature of salty water in the basin of the solar desalter and, as a result, increased volume of fresh water production.
