FIELD: process engineering.
SUBSTANCE: invention relates to agriculture, particularly to sea water desalination and can be used for purification of sweet water. Sweet water can be produced by evaporation and condensation of water vapours in costal areas and at sea platforms. Sea water desalination includes its evaporation and condensation of water vapour. Sea water is taken separately from top warm and cold bottom layers. Note here that warm water is forced to evaporation while cold water is used for condensation of water vapour resulted from heated sea water and atmospheric air.
EFFECT: lower power and metal input, higher efficiency of desalination.
