METHOD FOR SEA WATER DESALINATION Russian patent published in 2018 - IPC E03B3/28 C02F1/14 

FIELD: water treatment.

SUBSTANCE: invention relates to methods of autonomous fresh water production by evaporating sea water and condensing a steam-air mixture and can be used for drinking water supply, as well as for household needs. Method of desalination of sea water includes the placement of energy generators forming a steam-air flow, cooling of water vapor in condensers and selection of fresh water. Energy generators are made in the form of lenses collecting sunlight with the lens placed on the main optical axis in the focus of the lenses of solar energy pullers rigidly connected to the lenses, for heating and evaporation of sea water. Pullers are supplied with incoming water conduits and outgoing steam lines. Outgoing steam pipelines and incoming water conduits are connected to heat exchangers for recuperation of heat of condensation and heating of sea water. Energy sweepers, heat exchangers, water lines and steam pipelines are installed inside hollow floats with positive buoyancy, the lids of which are lenses. Incoming waterways are reported at the bottom of the floats with surrounding seawater. Floats are assembled on the surface of the sea, they regulate their buoyancy, ensuring the presence of seawater inside the energy pullers at the focus of the lenses. Lenses are oriented perpendicular to the sun's rays, using solar-tracking systems that feed on solar energy. Condensers are located at the bottom of the floats below sea level. Horizontal fixation of floats during sea waves and their specified buoyancy is provided by cargo suspended by cables to the bottom of the floats. Waterways and steam pipelines are partly flexible to support the work of the sun-watching systems.

EFFECT: invention provides increased productivity of the method for producing fresh water.
