Description
Technical field
The present invention relates to the technical field that solar energy and wind energy integrative utilizes, refer to utilize solar wind-energy seawater and brackish water desalination device and method of replacing especially
Background technology
According to the data that the World Bank provides, China's year per capita the water resources owning amount be about 2151 cubic metres, this has only 1/4th of world average level, is one of country that the own water stock number is minimum per capita in the world; And the north per capita the water resources owning amount have only 757 cubic metres every year, less than southern 1/4th, be about 1/11st of world average level, be lower than usually 1000 cubic metres of state's value levels that are defined as " water is rare ".
Solar wind-energy be use not to the utmost, inexhaustible renewable energy source, clean nontoxic and non-environmental-pollution, and the area of lack of water arid often all is the resourceful area of solar wind-energy; In solar radiation intensive season, it also just in time is maximum season of demand fresh water.Therefore, utilize solar wind-energy seawater or the brackish water desalination engineering of benefiting the nation and the people and helping environment of can yet be regarded as.
See that from geographical environment China is fit to the sea water desaltination of development solar wind-energy very much, because China's shoreline total length is 3.2 ten thousand kilometers, wherein mainland coastline is 1.8 ten thousand kilometers, 1.4 ten thousand kilometers in shoreline, island.Along with Global climate change, the situation of China's lack of water is serious all the more in addition, so, how " to want " fresh water to the sea, do not have the island of thermal source to obtain fresh water and become a problem.
Will provide thermal source to evaporate seawater at present, need seawater or brackish water temperature higher, the domestic vacuum heat collection pipe that generally occurs all is low temperature (being lower than 80 ℃); Producing hot water is used to have a bath etc.; But concerning sea water desaltination, such temperature is still not enough, and efficient is not high.How to improve the fresh water production output, key is the raising in the Hot swapping temperature.
Summary of the invention
The present invention mainly adopts a plurality of sun power cambered surface reflection thermal-arrest plates; Thermal-arrest plate cambered surface reflection heat build-up point is gone up with support many thermal-collecting tubes is installed side by side, is marked with thermostable heat-conductive oil in the thermal-collecting tube, in the thermal-collecting tube high temperature heat conductive oil after the solar heating is driven pneumatic pump by wind energy compressor; Circulation constantly is input to thermal-arrest to be changeed in the thermic devices; The seawater or the brackish water that change in the thermic devices with thermal-arrest carry out the heat conversion, make seawater or brackish water temperature after the conversion can reach 100 ℃, and wind energy compressor drives pneumatic pump high temperature seawater or brackish water are sprayed with splash head in vaporizer; Obtain a large amount of water vapour; Water vapour utilizes the cold of seawater that fresh water is condensed, thereby in fresh-water tank, obtains fresh water up to standard through condensing surface.
The high density seawater that sprayed or brackish water through preheating can to new seawater tentatively heat the back discharge back marine or the lake in; The seawater or the brackish water of just heating through preheating can carry out the high temperature shift heating by wind energy compressor drive pneumatic pump injection thermal-arrest commentaries on classics thermic devices.
For a large amount of displacement fresh water, can set up a plurality of thermal-arrest plates, multichannel high temperature heat conductive oil pipe input thermal-arrest is changeed the temperature replacing velocity that increases seawater or brackish water in the thermic devices.
Implementing process of the present invention is simple, and is cheap, and significant advantage is arranged on energy efficiency, and safe and reliable, aquifer yield is big, and water cleaning is up to standard; Can reduce the water production rate cost of unit collector area, because facility is simple, flow process is simple and direct as far as possible, easy to use and maintenance, and maintenance workload is little, helps on the island and environmental protection and energy saving are used in area that the brackish water lake lacks fresh water.
To achieve these goals, technical solution of the present invention is: the first step, and by a plurality of sun power cambered surface reflection thermal-arrest plates, thermal-arrest plate cambered surface reflection heat build-up point is gone up with support many thermal-collecting tubes is installed side by side, is marked with thermostable heat-conductive oil in the thermal-collecting tube; In second step, in the thermal-collecting tube high temperature heat conductive oil after the solar heating being input to thermal-arrest by the circulation of wind-force pneumatic pump changes in the thermic devices, and the seawater or the brackish water that change in the thermic devices with thermal-arrest carry out the heat conversion.In the 3rd step, the wind-force pneumatic pump sprays high temperature seawater or brackish water in vaporizer, obtain a large amount of water vapour; The 4th step, the high density of spraying and brackish water pass through preheating can to new seawater tentatively heat afterwards discharge back marine or the lake in; Seawater or brackish water through preheating can heating just carry out the high temperature shift heating by wind-force pneumatic pump injection thermal-arrest commentaries on classics thermic devices; In the 5th step, water vapour utilizes the cold of seawater that fresh water is condensed, thereby in fresh-water tank, obtains fresh water up to standard through condensing surface.
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Accompanying drawing is solar wind-energy seawater of the present invention and brackish water desalination device and method of replacing synoptic diagram.
Among the figure: 1, solar panels cambered surface reflection thermal-arrest plate, 2, thermal-collecting tube, 3-1. 2. 3. 4., the wind-force pneumatic pump, 4, thermal-arrest changes thermic devices; 5, vaporizer, 6, preheating can, 7, condensing surface, 8, fresh-water tank; 9, splash head, 10, wind energy compressor, 11, seawater gets into and add pipe, 12, the water outlet pipe; 13, condensing surface preheating seawater water inlet pipe, 14, the discharging mouth of pipe, 15, condensing surface circulating seawer, 16, support.
