Desalinization is that conventional desalination technology is hot method desalinization using the method production fresh water of seawater desalination
Technology, mainly there is multi-effect flashing steam method and low-temperature multiple-effect distillation.Multi-effect flashing steam method is by the seawater by heating, successively in multiple
It is evaporated in the flash chamber that pressure is gradually reduced, steam is condensed and fresh water is obtained；Low-temperature multiple-effect distillation is will be a series of
The horizontal tube sprinkling falling-film evaporator that pressure is gradually reduced is together in series, and is input into evaporator with a certain amount of steam, by many
Secondary evaporation and condensation, so as to obtain being multiple times than the desalination process of the distilled water of quantity of steam.
But either multi-effect flashing steam method or low-temperature multiple-effect distillation, are required for building up large-scale desalinization dress
Put, the device relies primarily on the waste heat of the generations such as steam power plant, steel mill, chemical plant, there is significant limitation in terms of addressing,
And being on a grand scale due to above-mentioned sea water desalinating unit, it is necessary to large batch of production fresh water, so could effectively reduce every
The production cost of ton fresh water, thus this characteristic determines that they can only be adapted to the fixation in the region of large area and use, it is uncomfortable
For it is small-scale in the region of the small areas such as remote isolated island, rural area and ships, movably produce fresh water, the scope of application has
Significant limitation, it is not practical enough.
