Seawater desalting plant continuously supplied with solar heat and method thereof

The present invention relates to a seawater desalination apparatus and method for solar heating of a continuous, belonging desalination (including inland brackish water desalination) technology. Including water purification systems, seawater desalination system; water purification system by pumping Tihai wells, water sterilization clarifier, multi-stage ultrafiltration cell, consisting of net sea pool. Seawater desalination system solar concentrating collector by means of solar heat storage tank, a net water heater, and water composed of multi-stage flash. The solar concentrating collector means for collecting the working medium by a heat energy of sunlight during the day, stored in the heat storage tank, and then the thermally conductive working fluid is heated to a certain net water temperature, the hot water exports multi-stage flash evaporator, steaming stepwise, isolated freshwater and salt brine. The present invention can be dispersed relatively efficient collection of solar heating evaporation seawater, freshwater output quality drinking water standards, store solar energy for the production of continuous operation at night when no light fresh water, desalination rate of 40% greater yield.
