Distillation of salt water with solar heat
专利汇可以提供Distillation of salt water with solar heat专利检索，专利查询，专利分析的服务。并且PURPOSE: To produce fresh water from salt water at a high efficiency, by combining a solar energy collector with a multiple-effect evaporator, and controlling a temperature of an energy collecting water at its inlet side in accordance with a temperature necessary for the evaporator.
CONSTITUTION: Sea water sucked up by a pump 28 is used for cooling vapor from the third evaporator III, and then partially carried to the group of horizontal heat pipes 4. An energy collecting water, which was controlled according to a temperature of the first evaporator I, is also carried to the horizontal heat pipe group 4 for heat exchange with the sea water. Due to this heat exchange, vapor is generated from the sea water. This vapor is used for preheating sea water in a preheater 8, and carried to the second evaporator II for heat exchange with a condensed brine. In summer much solar energy is collected, so the temperature difference between the last cooler 2 and the horizontal heat pipe group 4 of the distillator 1 is kept great, resulting in the production of a larger amount of fresh water. In winter little energy is collected, so the distillator cunsumes an energy corresponding to the collected little energy. Thus, the distillator is operated continuously day and night, and fresh water can be produced at a high efficiency.
