Background technology
Along with social progress, development and the raising of industry, agricultural production industry and domestic life, increasing to energy demand, our times energy structure situation is more and more severeer, climate change becomes clear day by day, and environmental pollution is serious all the more, faces unprecedented challenge, energy-saving and emission-reduction are very urgent, are badly in need of development new forms of energy and more Freshwater resources.
The fundamental research of new forms of energy field of sea water desalting technology concentrates on:
1. passive type desalination water method, changes driving by sun power and envrionment conditions, completely naturally as traditional solar distilling pond, multiple-effect solar still, multistage flash distillation device etc.;
2. active desalination water method, prepares a small amount of power consumption of fresh water needs, also needs to be equipped with the extra means such as blower fan, water pump simultaneously, and heat and mass transfer enhancement effect improves system performance;
3. wind energy, sea energy drive air pressure and hydro-pump, and reverse osmosis seawater desalting and energy recovery combine;
4. realize energy cascade utilization, the composite system of above-mentioned technology and other correlation technique integrated application etc., as combined with solar energy greenhouse, combine with the techniques such as distillation and flash method of calming the anger etc.
Active method for desalting seawater is owing to having improved the heat and mass effect of desalting equipment, and vaporization temperature and condensing temperature can separately regulate and control, and extremely payes attention to.Energy in desalting process, moisture, salinity reclaim, heat and mass transfer process strengthening, fouling characteristic in parts, the raising of efficiency of energy utilization and producing water ratio etc. is the emphasis of research, it is mainly the solar energy collector of middle low-temperature level that solar energy converting is utilized link, the equipment combination relevant to the techniques such as distillation, flash distillation, pressure steam distillation and various heat and mass transfer process, Wind Power Utilization is mainly used in wind-power electricity generation, then drives hydro-pump reverse osmosis seawater desalting mode.

Step 5: wet air pressurized, heated, enter condensing chamber, condense into fresh water and middle pressure freezing air, separate by air water separator, middle pressure freezing air enters gas drive liquid pressurized cylinder by vapor pipe, produces high pressure water and enters reverse osmosis and energy recycle device, fresh water enters fresh-water tank and stores, and offers user;
Step 6: without the sun but while having wind, open bidirectional control valve, high-pressure air directly drives gas drive liquid pressurized cylinder through high pressure gas pipeline, produces high pressure water to reverse osmosis and energy recycle device, carries out sea water desaltination when long-time;
Step 7: when long-time calm but when the sun is fine, open bidirectional control valve make after dehumidification through gas-liquid separator out in force down warm freezing air and oppositely get back to ultrasonic wave atomizing nozzle, make pre-hot sea water atomization, drive separately humidification dehumidification sea water desaltination.
9. the desalination method that a kind of sun energy line optically focused-wind energy synergistic supersonic wave sea water desalinating plant as claimed in claim 8 adopts, the fixing bar shaped minute surface solar concentrator of described step 3 reflexes to solar ray on glass metal valve tube resorber, glass metal valve tube resorber is followed the tracks of sun line optically focused, enter glass metal valve tube resorber by solar energy collector intake pump from fresh-water tank part water coolant out, be heated to form High Temperature High Pressure hot steam in 110-170 DEG C.
