Background

Along with the explosive growth of global population and the change of daily difference of industry and agriculture, the urbanization process is now compared with the original water resources of many areas, and basically, the water resources belong to supply shortage, and the water resources are transferred from other places to solve supply and demand, so that the water resources are not required to be maintained, and cannot be timely treated even after being polluted, and the supply and demand of the water resources are more unbalanced. In the world, the fresh water required by the production of various national industrial and agricultural lives is remarkably pretty, and even worse, a water source meeting the drinking specification of human beings cannot be found in many regions. Therefore, how to solve the daily supply problem of fresh water has become a great problem to be considered urgently by all mankind and related to the survival development of mankind. The research of the seawater desalination technology is a scientific research of great significance, and the seawater desalination technology is a process for desalinating seawater to be fresh water or fresh water. In the world, fresh water resources are deficient, and the research of a high-efficiency and low-cost seawater desalination technology becomes a research hotspot in the field of seawater desalination.

Most of the existing seawater desalination devices utilize solar energy as a heat source, are environment-friendly and harmless, are inexhaustible, and accord with the concept of sustainable development. Compared with the traditional desalination technology with high energy consumption and high pollution, the method has quite high application value. However, there is a part of heat loss in evaporation by using solar energy, and reducing the heat loss can improve the evaporation efficiency, so it is important to design a seawater desalination scheme that uses solar energy as a heat source and can reduce the heat loss.

At present, the seawater desalination technology mainly comprises a multi-stage flash evaporation desalination technology, a multi-effect evaporation desalination technology, a reverse osmosis membrane method and the like, although the device continuously optimizes the performance, the inevitable problem is that the energy consumption is still high, in the multi-stage flash evaporation desalination technology, the continuous circulation of seawater aggravates the energy consumption, in the multi-effect evaporation desalination, the phenomenon of salt deposition is very serious, and the reverse osmosis method mainly utilizes a semi-permeable membrane to separate solute from solution in the seawater under the action of pressure to obtain fresh water. The device described in chinese patent 202110084222.6 belongs to one of membrane methods, and it seems that it is realizable to utilize the capillary principle to make seawater permeate the water-absorbing film and reach the evaporation chamber, and can also complete the process of seawater desalination to a certain extent, but under the long-time overload work of this process, it may cause the pore of the water-absorbing film to be blocked by the deposited salt, and the seawater finally can not reach the evaporation chamber below the spherical membrane, and finally can cause the seawater desalination device to be unable to work.
