Description
Technical field
This utility model relates to generation technology, particularly relates to hot wind tower electromotor.
Background technology
1978, Germany professor J.Schlaich proposed the conception of solar chimney generating, is subsidized by one electric power cartel of German Government and Spain subsequently, builds up First solar chimney electric station in the world in nineteen eighty-two in Spain.The chimney height in this power station is 200m, Diameter of chimney 10.3m, and thermal-arrest canopy overlay area diameter is about 250m.On daytime, the rotating speed of turbogenerator is 1500rpm, and output is 100kW；At night, the rotating speed of turbogenerator is lO00rpm, and output is 40kW J.
3 kinds of mature technologies are successfully combined as a whole by solar chimney generation technology: greenhouse technology, chimney technology and wind turbine machine technology.The transparent materials such as thermal-arrest canopy glass or plastics build up, and with metal framework as support, certain gap (height is H) is left on thermal-arrest canopy surrounding and ground.The sun visible ray (shortwave radiation) of about 90% can be absorbed through transparent thermal-arrest canopy by ground in canopy (a diameter of R), simultaneously because greenhouse effect, thermal-arrest canopy can intercept the long-wave radiation that ground sends well.Therefore, solar energy heating canopy is an effective trapping and the storage system of solar energy.Air themperature in heat exchange between air (temperature is Ti) makes thermal-arrest canopy in heated ground (temperature is T) and canopy in canopy raises, heated air rises owing to density declines, enter the chimney (radius is r, and height is H) in the middle part of thermal-arrest canopy.Cold air outside canopy (temperature is T) enters thermal-arrest canopy by the gap of surrounding simultaneously, and in material is thus formed thermal-arrest canopy, the continuous of air flows.Hot-air rate of climb in chimney improves, and ascending air promotes turbogenerator operating generating simultaneously.
Solar chimney generation technology, after proposing, extensively receives concern.Start until now from the eighties in 20th century, solar chimney generating and correlation technique have been carried out a series of research by the U.S., Germany, Spain, India, Australia, Egypt, some countries such as brother and South Africa that rub.It is 10m that nineteen eighty-three American scientist Krisst has built a chimney height, the courtyard-style device of solar generating _ 3J of thermal-arrest canopy diameter 6m, output 10W.The solar chimney model having built three kinds of different types for 1997 in Univ Florida USA garden has carried out substantial amounts of theory and experimentation.The plan building a 100MW solar chimney electric station in the Thar Desert of the La Jiasitan of India was once proved and was come into effect, but owing to the core contest between India and Pakistan makes this fail in one's scheme.Rise since nineteen ninety-five, by physicist Wolf Wo Erte ·；The group of Si Tingna leader have pointed out the plan desert city stannum outlying in South Africa in 2016 emerging near construction 200MW solar chimney electric station scheme, but this huge plan still suffers from many huge difficulties, and wherein required 1500m chimney stack plan is unprecedented.
Solar chimney generation technology is paid close attention to the most widely, be primarily due to it has the advantage that
1) solar chimney generation technology is eco-friendly clean energy resource; will not produce environmental pollution as fossil energy, solar energy is the most inexhaustible; solar chimney generation technology is the exploitation of regenerative resource, and to alleviating, the most serious energy crisis is significant.
2) solar chimney generation technology is suitable for building on underpopulated idle soil, this world today fallen sharply for cultivated area also has important practical significance, therefore solar chimney generation technology is particularly suitable for the west area that China is wide, and unique contribution is made in the development of the West Regions for China.
3) solar chimney generation technology is a kind of well solar energy transformation technology, and the solar energy of thermal-arrest canopy ground absorption can generate electricity not only daytime, and also can release energy in the evening, it is ensured that the continuous operation of generating set.
4) solar energy heating canopy and chimney material all can use existing conventional material, and equipment relatively other generation technology is simple, and operating cost is low；And equipment scale is the biggest, power is the biggest, and the efficiency of generating is the highest, economy is suitable for set up powerful solar chimney electric station.
5) solar chimney generation technology is except being utilized in addition in energy development, in recent years for improving the air diffusion in some areas, eliminates the research report on local air pollution the most a lot.
Solar chimney generation technology is since the Hispanic First demonstration project of 1978, so far still without building up large-scale solar power plant, is primarily due to this technology and there is also following shortcoming:
1) transparent material of thermal-arrest canopy, it is easy to by dust lid, not easy cleaning, make the heat exchanger effectiveness of transparent material decline.
2) under strong wind, transparent material is easily destroyed.
3) safety problem that the Radix Saposhnikoviae of super-high chimney is shockproof also further study.
4) compared with common wind energy conversion system, the turbogenerator in the solar chimney of big structure is non-remunerative economically.
5) solar chimney takies a large amount of land area.
Having a large amount of waste heat to utilize in view of industrial, utilize industrial exhaust heat to be transformed into hot blast, in the thick hot wind tower of similar chimney, hot blast rises along chimney, equally generates electricity, need not take again a large amount of soil, and such device can be referred to as hot wind tower electromotor.
