DEVICE FOR SEA WATER DESALTING AND METHOD OF USING OF SOLAR ENERGY FOR CONTINUOUS SUPPLY OF HEAT

FIELD: hydraulic engineering.SUBSTANCE: invention relates to a device and a method for sea water desalting using solar energy for continuous supply of heat and to scope of sea water desalting (including desalting of internal brackish water). Invention can also be used in treatment of waste water. Device comprises a system of treatment of sea water and sea water desalting system, where sea water treatment system consists of a well for extraction of sea water, reservoir for sterilizing treatment of sea water multistage ultra filter and tank for purified sea water; and sea water desalting system consists of a device for concentration of solar energy and heat collection, storage tank of heat solar energy, heater of purified sea water and multistage instant evaporator of sea water. Device for concentration of solar energy and heat accumulation accumulates thermal energy of sun light by means of heat-conducting working medium in the afternoon, saves thermal energy of sun light in the tank for storage of heat solar energy and then heat purified sea water by means of heat-conducting working medium to a certain temperature; hot sea water is directed to multi-step instant evaporator of sea water, and sprayed and evaporated stage by stage, and fresh water and brine are separated. Also disclosed is a method of sea water desalting using solar energy for continuous supply of heat.EFFECT: device for sea water desalting using solar energy for continuous heat feed, can effectively collect relatively dissipated solar energy to heat and evaporate seawater, quality of fresh water reaches the drinking water standards, and solar energy is stored, enabling continuous operation of obtaining fresh water.10 cl, 2 dwg Изобретение относится к устройству и способу для опреснения морской воды с использованием солнечной энергии для непрерывной подачи тепла и к области опреснения морской воды (включая опреснение внутренней жесткой воды).
