Description
Technical field
The utility model relates to a kind of distributed solar energy modularization multitower concentrating generating system, belongs to solar energy generation technology field.
Background technology
At present, along with the growing tension of the energy, regenerative resource obtains academia, the wideling popularize of national governments; Wherein, solar energy, as a kind of green, free of contamination regenerative resource, obtains significant progress in recent years;
In the utilization of solar energy, conventional mode is for adopting photovoltaic power generation plate, directly sunlight is converted to electric energy by photovoltaic effect, but, because solar energy shot densities is at the earth's surface lower, the electric energy causing the solar panel of unit are to obtain is lower, thus make as obtaining a large amount of electric energy, the area of solar panel can only be expanded, thus its use cost is greatly increased, the unit price of power obtained also significantly improves, and compared with traditional thermal power generation, the market competitiveness greatly weakens; For this reason, company is had to develop condensation photovoltaic (CPV) generation technology, logical for sunlight after convergence being radiated on photovoltaic battery panel generates electricity by it, so a large amount of uses decreased photovoltaic battery panel, greatly reduce cost of electricity-generating, but there is bottleneck equally in this type of mode, owing to being limited to the light-photoelectric transformation efficiency of solar panel, also only can reach 28% because the efficiency of light energy utilization is the highest, a large amount of solar energy is wasted;
For this reason, industry develops solar heat power generation system, and solar heat power generation system forms primarily of concentrator, heat collector, heat accumulation/combustion-compensating device and thermal electric generator; Compared with solar photovoltaic generating technology, the maximum advantage of solar energy thermal-power-generating technology is that the free of discontinuities that cheap heat accumulation/combustion-compensating device can be used to realize power station is run, and is continuously customer power supply; In addition, along with the expansion of power plant scale, solar energy thermal-power-generating cost can reduce further and realize, with the competition of traditional fossil energy, therefore having good development prospect; Meanwhile, China's solar radiation aboundresources, the prospect of development solar energy thermal-power-generating is boundless;
Conventional solar energy thermal-power-generating condenser system, comprises slot type, tower, dish-style, linear Fresnel formula and ground receiver formula;
Wherein tower condenser system is made up of Jing Chang, tower and tower top heat dump; High density in tower top heat dump, then can be circulated to turn to heat energy and be transferred to ground by heat-transfer working medium (being generally high steam) by heat dump and generates electricity by Jing Chang by low-density solar radiation; Jing Chang is arranged by heliostat and forms, and heliostat realizes following the tracks of the three-dimensional of the sun around dual-axis rotation, and is reflexed on tower top heat dump by sunlight.The condenser performance of heliostat determines the quality of mirror field hot spot; The face shape of heliostat has plane and two kinds, curved surface, and planar heliostats is applicable to low tower structure, and processing is debug simple, and cost is low, ensure that field, good border hot spot effect.Due to light without converging action, heliostat size is general less, to ensure less mirror field hot spot.Toroidal heliostat processing is debug more difficult and cost is high, but condenser performance is better. and heliostat can do very large;
In sum, tower condenser system is the forms of electricity generation being suitable for large-scale popularization at present with regard to economy, practicality most, its simple structure, making and installation are with low cost, thus make cost of electricity-generating low, can contend with thermal power generation after large-scale application, therefore there is most the prior art of market prospects;
But, conventional tower condenser system is obtain larger power, need abundant floor space, arrange that abundant reflection mirror array provides luminous energy to it, so optically focused tower structure is made higher and higher, often reaches the above height of more than 100 rice, and its construction difficulty and safety issue are greatly increased, and heliostat field occupation of land also needs very large area, these bring inconvenience to the installation of scene.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of in-site installation convenient and the distributed solar energy modularization multitower concentrating generating system that fail safe is high.
The purpose of this utility model is achieved in that a kind of distributed solar energy modularization multitower concentrating generating system, described system includes multiple heat collecting module, each heat collecting module all includes the heat absorbing heat exchanger being installed on low top of tower, and described low tower periphery is provided with the reflective array be made up of multiple speculum.
A kind of distributed solar energy modularization of the utility model multitower concentrating generating system, each speculum in reflective array is the level crossing adopting special process, and sunlight being reflexed to the set of heat absorbing heat exchanger relief low-density solar energy becomes the utilance that highdensity energy improves solar energy.
Compared with prior art, the beneficial effects of the utility model are:
The utility model adopts modularized design, selects the heat collecting module of respective numbers can form the solar energy concentration generating system of corresponding demand power according to customer demand, and easy to assembly, and reproducibility is high; Compared to traditional single tower structure, after modularized design, single high tower becomes multiple low tower structures, each low tower its only need receive periphery among a small circle within sunlight, floor space is reduced to less, be suitable for surrounding city to use, because it is highly lower, easy for installation, reduce difficulty of construction and cost, Environmental Safety and reproducibility good, and by combination expand power, contribute to applying of the utility model system.
