Description
Technical field
The utility model relates to field of sea water desalting technology, and particularly a kind of wind power generating set that adopts is the reverse osmosis desalination device of system's power supply.
Background technology
China's Coastal Areas has abundant seawater resources, and making full use of seawater resources by sea water desaltination is to solve main path coastal, the offshore area shortage of fresh water.Sea water desaltination claims again " sea water desalinization ", obtains the technology of fresh water exactly from seawater.The desalination technology of practical application at present is mainly distillation method and reverse osmosis membrane two big classes, and distillation sea water desalting mainly uses heat energy, and electric energy is mainly used in the reverse osmosis membrane sea water desaltination.Compare with distillation method, reverse osmosis membrane desalinizes seawater and has advantages such as investment is little, energy consumption is low, take up an area of less, the construction period is short, easy and simple to handle, be easy to control, and since entering desalination technology market, its engineering is used in rising trend always.Reverse osmosis membrane is to adopt the selectivity semipermeable membrane device, when the communicating vessels brine side to liquid pressure during greater than osmotic pressure, water molecules in the salt solution will advance people's dilute side and solute still is isolated from brine side by semi-permeable membranes by semi-permeable membranes, cause brine concentration to strengthen, this process is opposite with the normal process of osmosis of nature, is called reverse osmosis.For reverse osmosis unit is normally moved, brine side pressure must be higher than osmotic pressure, and pressure is relatively stable, and generally in 4 ~ 6MPa scope, at this moment film allows the water molecules in the seawater to see through, and most molecules of salt are stopped, thereby obtains fresh water.
Sea water desaltination is the energy-intensive industry, because the desalination technology main process is ripe relatively, is that effective combination is carried out in sea water desaltination and power supply so reduce the main path of sea water desaltination cost, realizes the optimization utilization of the energy.In recent years, new forms of energy especially the fast development of wind-powered electricity generation become the new research field of sea water desaltination development for sea water desaltination provides new thinking.
1999, Spain has carried out independent wind power generation seawater desalination research, and carried out test in place in the sharp archipelago of Ghana, successively the feasibility of wind-powered electricity generation independent operating sea water desaltination, the desalination technology of the most suitable wind-powered electricity generation independent operating have been studied, by the direct sea water desaltination of the most suitable wind-powered electricity generation of evidence reverse osmosis technology.Recently certain research has been done aspect the sea water desaltination in that wind-powered electricity generation is directly used in by Germany, has gone out the reverse osmosis wind power generation seawater desalination system of moudle type in conjunction with its own aerogenerator product development, and at Norway's Utsira island trial run.China Chinese Academy of Sciences Guangzhou energy is carrying out the multiple complementary sea water desaltination of wind-powered electricity generation-diesel oil-sun power experimental study.According to domestic and foreign research results, the direct sea water desaltination of wind-powered electricity generation is feasible fully technically, and more existing small-sized checking demonstration projects are built up and operational excellence.
