Method for desalting seawater mainly divides two major classes, and one kind is membrane separation process, such as reverse osmosis, electrodialysis, membrane distillation, another
Class is the way of distillation, such as single-stage distillation, multiple-effect evaporation, multistage flash distillation, and membrane separation process is represented directly generates fresh water with electric energy
Developing direction, device is simple, is easy to that miniaturization, low energy consumption for specific yield, but this method sea water preprocessing device is complicated, film
Layer is expensive, and daily maintenance is costly.The way of distillation uses a large amount of thermal energy, generates fresh water by the evaporation and condensation of water, repeats
It using the latent heat of vapor and condensation process, is allowed to while preheating raw water, condensed steam becomes freshwater product.
Multiple-effect evaporation and multi-stage flash process are generally realized by cogeneration of heat and power mode, and the vapour of water can be used repeatedly
Change latent heat, the fresh water yield of specific energy consumption is higher, however, the energy used mostly at present is solar energy, solar radiation quantity variation
Greatly, and the only conversion between thermal energy and electric energy, cause the supply and demand of thermal energy to be difficult to synchronize sometimes so that multiple-effect evaporation and
Multistage flash distillation is difficult steady-state operation, in addition, multistage flash distillation process needs accurate pressure control, and must be tieed up between different series
Constant pressure difference is held, therefore, solar energy multiple-effect evaporation and multi-stage flash process are difficult to realize.
It clicks distillation and is divided into nature evaporation type and vacuum boiling type.The vaporization that nature evaporation type cannot reuse water is latent
Can, the daily output of unit area is relatively low, and heat transfer is slow, and heat loss is big, and efficiency is low；Vacuum boiling type can reuse the vaporization of water
Potential, but equally face for thermally labile, supply and demand be difficult to it is synchronous to can not steady-state operation the case where.
