Description
Technical field
The utility model belongs to the desalination with Solar Energy field, relates in particular to a kind of self-supporting moisturizing disc type solar energy sea water desalinating plant.
Background technology
The ocean covers 71% of earth surface-area, and the seawater reserves are about 13.7 hundred million cubes of kms, account for 95% of global Total Water; Land fresh water reserves are about 0.35 hundred million cube of km, account for 2.53% of global water reserves, wherein can only account for 0.266% of fresh water reserves, 7/100000ths of the total moisture storage capacity of the not enough earth for the human fresh water that directly utilizes.China's seashore line length, all there are serious shortage of fresh water problem in a lot of island, coastal and landlocked brackish water area.Therefore, the development desalination technology to alleviate current shortage of fresh water, the imbalance between supply and demand distinct issues have far-reaching strategic importance.
Sea water desaltination is exactly that the salinity in the seawater (or brackish water) is separated with moisture, finally obtains the process of fresh water and concentrated salt solution.The most frequently used technology of seawater (or brackish water) desalination mainly contains multiple-effect distillation, multistage flash evaporation method, reverse osmosis method, extraction process and electroosmose process.
Multiple-effect distillation is that the heating of seawater distillation is produced steam, and steam produces fresh water and emits latent heat in the process of condensation, and fresh water flows into fresh-water pool, and latent heat is used for the seawater of next effect of heating and produces steam, carries out according to this multiple-effect utilization, reduces heat energy consumption.This process also needs the certain driven by power water pump of additive decrementation and blower fan except consuming heat energy.
The multistage flash evaporation method is that the seawater that is heated to certain temperature is introduced the flashing chamber that several pressure reduce gradually successively, because the pressure of flashing chamber is lower than saturated vapour pressure corresponding to seawater temperature, seawater is vaporized rapidly after entering step by step flashing chamber, salt concentration increases step by step, and temperature reduces step by step, because heat is from the decline of salt water self-temperature, there is not special hot face, avoid inorganic salt to separate out fouling, until discharge, obtained fresh water behind the vapor condensations at different levels.This process also need consume a large amount of driven by power vacuum pumps and water pump except consuming heat energy.
Reverse osmosis method is to utilize reverse osmosis membrane that seawater and fresh water are separated, and applies enough large pressure (surpassing penetration of sea water presses) in the seawater side, and dilute side is arrived in the water molecules reverse osmosis in the seawater.This method does not consume heat energy, produces enough large external pressure but need to consume a large amount of electric power, and is very high to the requirement of reverse osmosis membrane in addition yet.
Electroosmose process is take potential difference as power, and the selectivity of utilizing ion-exchange membrane sees through and removes the desalination process of water intermediate ion.Electrodeionization combines dialysis with ion-exchange, fill ion-exchanger in the freshwater room of electrodialyzer, under the effect of DC electric field, realizes the continuously process of electricity regeneration of electrodialysis, ion-exchange demineralization and ion-exchange.Electrodeionization is not used in brackish water desalination, mainly for the production of high purity water.This method does not consume heat energy, but needs to introduce electric power.
Cold method be with seawater freezing to below freezing, fresh water freezes, separates, melts is the process of fresh water.Cold method is utilized natural ice method and artificial cold method.But technology is still immature.
Traditional desalination technology investment is high, and energy expenditure is large, according to statistics, produces the device of 1,300 ten thousand tons of desalination waters every day, annual 1.3 hundred million tons of the consumption crude oil that need.Remove outside the expense of this fuel, the problems such as the Greenhouse effect that bring thus, atmospheric pollution also can not be ignored.With regard to China, can not set up traditional sea water desalinating plant on the boats and ships for the isolated island at sea and navigation.Solar seawater desalination fresh water technology is the effective way that solves these particular locality shortage of fresh waters, emergency survival problem, has a extensive future.
