Description
Technical field
The invention belongs to field of sea water desalting technology, particularly relate to a kind of sea water desalinating plant.
Background technology
Fresh water is the indispensable base substance that the mankind depend on for existence and produce.The water total reserves in the whole world is 13.88 hundred million km
3, seawater amount account for wherein more than 97%, and because seawater saltness is higher, thus the mankind directly can not drink it, and the total amount of remaining fresh water amount accounts for 2.53% of total moisture storage capacity on the earth.Moreover, even if in the fresh water of this small proportion like this, its distribution is extremely unbalanced again, wherein the fresh water of 98.8% is frozen among the polar region, north and south two of the earth and the glacier of severe cold areas, and is present in 0.36% of fresh water total amount on the not enough earth of fresh water that river, lake and underground water etc. directly can utilize for the mankind.China's seashore line length, all there is serious shortage of fresh water problem in a lot of island, coastal and inland brackish water area.Therefore, develop desalination technology, to the current shortage of fresh water of alleviation, imbalance between supply and demand distinct issues, there is far-reaching strategic importance.
Sea water desaltination is exactly be separated with moisture by the salinity in seawater (or brackish water), finally obtains the process of fresh water and concentrated salt solution.Seawater (or brackish water) is desalinated the most frequently used method and is mainly contained multistage flash vaporization, multiple-effect distillation, reverse osmosis method, extraction process and electroosmose process.
Multistage flash evaporation (MSF) technology introduces flashing chamber after raw material seawater is heated to certain temperature, because the pressure in flashing chamber is lower than the corresponding at such a temperature saturated vapour pressure of raw material seawater, thus raw material seawater became hot solution after entering flashing chamber, part is crossed hot sea water and is evaporated rapidly, the temperature of raw material seawater self reduces, and the vapor condensation produced discharges the circulating seawer that latent heat comes in preheating prolong at the corresponding levels.
Multi-effect distilling (MED) is occurred outward by the heat transfer tube of seawater equably in the first single-effect evaporator being heated to working temperature to spray falling liquid film, then in heat transfer tube, a certain amount of heat source stream is passed into, the heat of condensation of releasing is utilized to make the seawater outside pipe produce secondary steam by thermal evaporation, secondary steam is as the heat source stream of lower 1st effective evaporator, all there is similar process in later each single-effect evaporator, thus obtain the fresh water amount being multiple times than steam input, apparatus structure more complicated and huge.
Reverse osmosis method utilizes reverse osmosis membrane seawater and fresh water to be separated, and applies enough large pressure (exceeding penetration of sea water pressure), by the water molecules reverse osmosis in seawater to dilute side in seawater side.This method does not consume heat energy, but need consume the enough large external pressure of a large amount of electric power generation, and device volume is huger.
Electroosmose process is power with potential difference, utilize the selectivity of ion-exchange membrane through and remove the desalination process of water intermediate ion.Electroosmose process is not used in brackish water desalination, mainly for the production of high purity water.
Cold method is by seawater freezing to below freezing, and fresh water freezes, be separated, melt process for fresh water again.Cold method due to refrigeration temperature low, energy consuming ratio is larger.
