The invention relates to a solar sea water evaporator. The solar sea water evaporator comprises a sea water pretreatment unit (1), a sea water tank (3), a lift pump (5) and a heat exchange water tank (8) which are sequentially connected, wherein the heat exchange water tank (8) is internally provided with a spiral heat exchange tube (9); the lower end of the spiral heat exchange tube (9) is provided with a fresh water collection outlet; an outlet at the lower side of the heat exchange water tank (8) is connected with a water inlet in one end of a solar heat pipe type heat collector (14); a water outlet in the other end of the solar heat pipe type heat collector (14) is connected with a solar still (21); condensation pipelines at the two sides of the solar still (21) are connected with a connector at the upper end of the spiral heat exchange tube (9) after passing through an air pump (20); the tail of the solar still (21) is provided with a fresh water collecting outlet and a strong brine collecting outlet. A solar sea water desalination core technology is adopted by the solar sea water evaporator, and the water production rate of solar sea water desalination is multiplied.
Description
technical field [0001] The invention relates to a high-efficiency and energy-saving seawater desalination device, in particular to a solar seawater evaporator. Background technique [0002] At present, the capacity of seawater desalination devices in the world is growing rapidly, at a rate of 10% to 30%, and the growth rate is still increasing gradually. More than 130 countries around the world are desalinating seawater, and more than half of the desalination capacity is concentrated in the Middle East Gulf countries, accounting for 70% of the Middle East's freshwater sources. There are mainly two kinds of engineering seawater desalination process routes at home and abroad: thermal method and membrane method. However, these two methods have the problems of complicated pretreatment, low localization of equipment, large energy consumption, and high processing costs. The comprehensive cost of seawater desalination per ton of water is about 8 yuan. It is difficult to use it o...
