According to the solar saline water desalination and comprehensive utilizationsystem and method, various saline water desalination technologies and solar energy resources are sufficiently utilized, energy consumption is reduced, the production of freshwater is increased and theeconomic feasibility of the project is improved.

Description

technical field [0001] The invention relates to a comprehensive utilization system and method for solar salt water desalination, belonging to the field of comprehensive utilization of solar energy. Background technique [0002] At present, there are many methods for desalination of salt water, such as distillation, reverse osmosis, electrodialysis, etc., each has its own advantages and disadvantages, as well as its own scope of application. The distillation method obtains fresh water by heating, vaporizing and condensing, and is not limited by the concentration of salt water. large, low water production efficiency, such as the publication date is September 30, 2015, and the publication number is CN104944485A in the Chinese patent, which discloses a distillation seawater desalination system and its desalination method; the reverse osmosis method uses reverse osmosis membranes, Reverse osmosis of high-pressure salt water to generate fresh water, because there is no phase chan...

Problems solved by technology

The distillation method obtains fresh water by heating, vaporizing and condensing, and is not limited by the concentration of salt water. large, low water production efficiency, such as the publication date is September 30, 2015, and the publication number is CN104944485A in the Chinese patent, which discloses a distillation seawater desalination system and its desalination method; the reverse osmosis method uses reverse osmosis membranes, Reverse osmosis of high-pressure salt water to generate fresh water, because there is no phase change, the energy consumption is small, but the concentration of salt water should not be too high, and the purity of the fresh water produced is not enough. For example, the public date is April 27, 2011, and the public number is In the Chinese patent of CN102030391A, a wind power generation reverse osmosis seawater desalination system is disclosed; the electrodialysis method is characterized in that salt ions are removed from salt water, and the energy conversion method is reasonable. Removes uncharged impurities and becomes less economical with increasing salt content

[0003] In the dry areas of Northwest my country and the eastern coastal areas, fresh water resources are relatively tight, there is a large amount of seawater or brackish water, and there is a demand for salt water desalination. However, the economics of a single salt water desalination method is limited by objective conditions.
