Description
Technical field
The present invention relates to the heat-transfer technology of a kind of high-temperature metal superconducting pipe, particularly a kind of superconduction geothermal power generation method.
Background technology
The mankind begin to utilize geothermal energy a long time ago, such as, utilize hot spring bath, medical treatment, utilize geothermal water heating, build crops greenhouse, aquaculture and dry corn etc., and the fairly large exploitation of geothermal energy resources started from 20th century.
The U.S. is enhancement mode geothermal system research country the earliest, and within 1972, two mouthfuls of deep inclined shafts of about 4000m have been beaten on U.S.'s Fenton mountain, carries out power first and reaches 2300kW, USDOE's report display, and to the year two thousand fifty, U.S.'s application strengthens geothermal system can realize 100,000,000 kW that install;Britain is the most second-biggest-in-the-world hot dry rock experimental project in the hot dry rock research project that Cornwall group implements, and project starts from 1977, within 2009, is supported by European Union;Britain plans is carried out " Garden of Eden project " Cornwall group, cost 87,000,000 pounds, this project hot storage space 4km under earth's surface, and whole site is expected to provide the electricity needs of up to 10% for Britain;Australia is that another one EGS progress is the most national, and it is movable that this Guo You 7 company is engaged in EGS, wherein the most notable with Geodynamics Inc.'s achievement.The said firm carries out power station test in the cooper basin of Australia, and once arrives China and seek moment of cooperation;Say this, the country such as German, French all carries out the water injection test of experimental power station, and obtains certain achievement EGS；
The research of EGS is started late by China's Progress In Geothermal Studies at present, Chinese Energy Research Institute underground heat Professional Committees in 2007 and Petratherm company of Australia sign cooperation agreement, to China's southeastern coast and Tibet, territory, big underground heat REGION OF WATER INJECTION OILFIELD, Yunnan two carries out studying to be developed, world's underground heat conference statistics in 2010, the whole world has 78 countries and is developing ground thermal technology, 27 countries utilize geothermal power generation, total installation of generating capacity is 10715MW, annual electricity generating capacity 67246GW h, mean utilization 72%, develop this renewable and clean energy resource, to Global climate change, promote geothermal energy resources further, particularly in the penetration and promotion application of China's shallow layer geothermal energy.
Geothermal power generation is the most important mode of geothermal utilization, and high-temperature geothermal fluid should be initially applied to generating, and geothermal power generation is the same with the principle of thermal power generation, is all that the heat energy utilizing steam is changed into mechanical energy in steam turbine, then drives electrical power generators.Except that, huge boiler is equipped in geothermal power generation unlike thermal power generation, it is not required that consuming fuel, its energy used is exactly geothermal energy.
The process of geothermal power generation, it is simply that underground heat energy is transported to ground, is being changed into mechanical energy by heat energy by heat energy machine system, by system engineering equipment, the process of the program electrical network transformed mechanical energy into electricity.When not losing geotemperature for realizing extraction underground heat, we have developed metal superconducting pipe.The natural steam of the thermophore that can be utilized by geothermal power station at present, mainly underground and hot water.According to the difference of thermophore type, temperature, pressure and other characteristic, currently available technology can the model split of BADIRE generating be steam type geothermal power generation and hot-water type geothermal power generation two class.
For this, we work out a kind of superconduction geothermal power generation method further.Metal superconducting pipe is the sealed tube body synthesized by vacuum and chemical mediator, one end of metal superconducting pipe is mixed with geothermal layer, by metal superconduction body, transfer thermal energy to rapidly carry out on ground thermal efficiency conversion, it is changed into mechanical energy by the thermal energy of steam-turbine, then mechanical energy is converted to a kind of stratum heat-transferring method of electric energy.
Summary of the invention
Geothermal power generation is the most important mode of geothermal utilization, high-temperature geothermal fluid should be initially applied to generating, geothermal power generation is the same with the principle of thermal power generation, it is all that the heat energy utilizing steam is changed into mechanical energy in steam turbine, then electrical power generators is driven, except that huge boiler is equipped in geothermal power generation not as thermal power generation, also without consuming fuel, its energy used is exactly geothermal energy, the process of geothermal power generation, it is exactly that underground heat energy is first converted into mechanical energy, the process transformed mechanical energy into electricity the most again.Underground heat energy to be utilized, it is necessary first to haveThermophoreThe heat energy of underground is taken on ground, the thermophore that can be utilized by geothermal power station at present, it is mainly natural steam and the hot water of underground, according to the difference of thermophore type, temperature, pressure and other characteristic, can the model split of BADIRE generating be steam type geothermal power generation and the big class of hot-water type geothermal power generation two；
Present thermophore is instead of for this high-temperature superconductor metal tube, and solve steam type geothermal power generation and the complex engineering of hot-water type geothermal power generation, improve the efficiency of heat energy, by direct for underground heat heating installation system generating, and supplying hot water is the geothermal utilization mode being only second to geothermal power generation.Because this Land use systems is simple, good economy performance, various countries are enjoyed to pay attention to.
In place of above-mentioned the deficiencies in the prior art, the invention provides a kind of high-temperature superconductor geothermal power generation method, the sealing metal superconduction body synthesized by vacuum and chemical mediator, one end of bad high-temperature metal superconducting pipe is mixed with geothermal layer, by heat-insulation metal superconduction body, transfer thermal energy to rapidly carry out on ground heat energy conversion, be mechanical energy by the thermal energy of steam-turbine, then mechanical energy is converted to a kind of stratum heat-transferring method of electric energy.
Superconducting metal heat pipe transmission speed is fast, has the thermal efficiency utilization amount that efficiently promotes, thus is fully solved the not enough problem of above-mentioned steam type geothermal power generation and hot-water type geothermal power generation.
The technical solution used in the present invention is: uses high-temperature superconductor metal tube to instead of present thermophore, including metal tube, has vacuum-sealed cavity in body, it is characterised in that: it is provided with tinsel in described vacuum-sealed cavity, vacuum-sealed cavity is filled superconducting fluid.
