Description

technical field [0001] The invention relates to a seawater desalination device utilizing solar energy and wind energy, in particular to a seawater desalination treatment device that does not have negative impact on the environment during operation and is suitable for use in places with abundant seawater resources such as cities near the sea and islands and reefs . Background technique [0002] my country is a country with serious shortage of water resources. At present, the acceleration of industrialization and urbanization in our country has resulted in serious freshwater pollution. With the depletion of fresh water resources, some cities are facing a serious shortage of fresh water, especially resource-based water-scarce coastal cities. In order to solve the problem of fresh water shortage, scientific research adopts the method of seawater desalination and sewage treatment to meet the country's demand for fresh water. However, sewage treatment consumes a lot of energy a...

Problems solved by technology

They generally have the disadvantages of large energy and material resource consumption and high cost.

[0003] Solar energy is widely welcomed as a clean, environmentally friendly and well-reserved energy source, but due to the problems of instability, low energy density and high cost, the utilization of solar energy is limited to a certain extent.

Wind energy is also a kind of clean energy, but because wind energy is regional and seasonal, it is difficult to promote it

[0004] As we all know, there are very few devices suitable for the treatment of living sea water on islands, which cannot solve the serious shortage of fresh water on islands and reefs, which directly restricts our country's military presence on islands and reefs, which has caused the problem of islands and reefs in the South China Sea to worsen day by day. Illegal occupation threatens the personal and property safety of fishermen, which indirectly affects the maintenance of territorial integrity and public safety in the South China Sea
