Background technology
Progress along with society, 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, fully naturally as traditional solar distilling pond, multiple-effect solar still, multistage flash distillation device etc.;
2. active desalination water method prepares fresh water and needs a spot of power consumption, also needs to be equipped with extra device such as blower fan, water pump simultaneously, and the 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 combining with solar energy greenhouse, combine with the technologies such as distillation and flash method of calming the anger etc.
Active method for desalting seawater is owing to improved the heat and mass effect of desalting equipment, and vaporization temperature and condensing temperature can separately be regulated and control, and extremely payes attention to.Energy in the desalting process, moisture, salinity reclaim, heat and mass transfer process is strengthened, fouling characteristic in the parts, the raising of efficiency of energy utilization and producing water ratio etc. is the emphasis of research, solar energy converting utilize link mainly be in the solar energy collector of low potential temperature, the equipment combination relevant with technologies 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, drives hydro-pump reverse osmosis seawater desalting mode again.
