Description
Technical field
The invention belongs to the energy, power technology field, it is specifically related to solar energy hot gas flow generating system.
Background technique
Along with world population quantity increases and industrial develop rapidly fast, the electricity power demand constantly increases, and energy crisis highlights day by day, and environmental pollution is also in aggravation, and the global greenhouse effect influence continues to rise, and the mankind's living environment progressively worsens.Non-renewable energy resources such as oil, rock gas exhaust at last, and countries in the world will be strengthened the dependence of the new energy demand of cleaning gradually.The new energy problem of each national capital special concern 21 century, and very good new renewable energy sources.Seek clean energy resource and utilize new technology to become one of research focus, and solar energy generation technology will be the most rising new energy technology.
German professor Schlaich proposed the solar chimney generation technology in 1978; Nineteen eighty-two Germany with Spain's cooperative construction first solar heat air-flow prototype power station of generating electricity; Adopt open printing opacity thermal-arrest canopy; Air is accepted solar irradiance and the temperature rising in the thermal-arrest canopy, forms the hot air flow that rises via chimney; Thermal-arrest canopy internal air pressure forms negative pressure because of the draft effect of chimney, and this negative pressure is ordered about the atmospheric air stream in the outer ground of thermal-arrest canopy and confluxed to thermal-arrest canopy center through the gas-entered passageway around the canopy, is discharged by the chimney top at last; Arrange wind turbine generator in chimney bottom; Hot air flow promotes the wind turbine generator blade, forms hot air flow generating (Schlaich J.chimney:Electricity from the sun [M] .Maurer C, Geislingen; Germany, The solar1995).
After Spain has built up first solar chimney power station, caused the strong interest of countries in the world, and developed a large amount of patented technologies in succession.Like patent: " the solar energy hot blast generating system of combing light voltage technology " (number of patent application: 200810034261.X) proposed to utilize hot blast generating and photovoltaic generation to fully utilize the technology of solar energy.Patent " heat collector that is used for solar energy hot blast power generation system " (number of patent application: 200810034259.2) through heat collector is improved, to improve the thermal efficiency of heat collector.Patent " a kind of device that utilizes solar energy to carry out chimney generation and desalination of sea water " (number of patent application: 200810021605.3) a kind of device that utilizes solar energy to carry out hot blast generating and desalination of sea water processing is provided.
So far, also do not have the solar heat air-flow power station to put into serial production operation, its main cause is that the existing technology generating efficiency is low excessively, and Economy does not have advantage.Find after deliberation; Except natural condition such as illumination; The solar heat air-flow generating efficiency is mainly relevant with the system physical dimension; Comprise diameter, road clearance of height, diameter, shape, the thermal-arrest canopy of chimney etc., especially the diameter of chimney height and thermal-arrest canopy is the remarkable influence factor of system's generated output and efficient.Along with the increase of chimney height, generating efficiency significantly rises, and also increases greatly but build difficulty.Australia promptly plans to build a solar heat air-flow power station in the beginning of this century, the design chimney is up to 1000 meters, but plan is so far stranded because of building reasons such as difficulty is big.Patent " a kind of superelevation smokestack wind-building generating system " (number of patent application: 200810002820.9) proposed a kind of material and construction process of superelevation chimney; The made chimney of ballistic fiber cloth is supported by the hot air flow that solar energy produces; Chimney can be up between the 2000-20000 rice as required; But when not enough, air-flow is difficult to support the huge chimney of height like this to this scheme, and this chimney does not have resistivity under storm condition at night or sunshine.
The another one difficult problem of solar heat air-flow generating is that transparent plane skylight is covered by dust easily, and is not easy to clean, and reduces lighting efficiency.
Summary of the invention
The purpose of the utility model solves mainly that the superelevation chimney is influenced easily by high wind to be destroyed, thermal-arrest plate transparency receives the dust accumulation affects to reduce the technical problem of lighting efficiency, solar beam dimness or generating at night, and a kind of solar energy hot gas flow generating system is provided.
The utility model is to solve the problems of the technologies described above the technological scheme of taking to be:
