Description
Technical field
The utility model relates to the solar energy generation technology field, relates in particular to a kind of sun power secondary condensation frequency divider based on dish formula optically focused.
Background technology
Global solar radiation amount about 1.7 * 10
17W, wherein China accounts for 1%(1.8 * 10
15W is equivalent to 1.9 trillion tons of mark coal/years), be present year 680 times of total energy consumption of China.Electric power is the secondary energy of consumption maximum in the world, and solar energy generation technology is an effective means of alleviating current energy crisis, and application prospect is extremely wide.
Solar energy generation technology mainly is divided into photovoltaic generation and photo-thermal power generation two big classes.Photovoltaic generation mainly is to utilize the photoelectric effect of photovoltaic battery panel to generate electricity.The main at present three big shortcomings that exist of this technology: (1) generated output changes with sunlight intensity, can not generate electricity fully with overcast and rainy at night, electrical network is impacted big; (2) the sunshine current density is low, and the required photovoltaic battery panel area of unit generating capacity is big, and the photovoltaic cell board manufacturing process is seriously polluted, cost is very high; (3) photovoltaic battery panel mainly concentrates on high-frequency short waves zone (400＜λ＜1100 nm) to the response wave band of solar spectral, the energy of low frequency Long wavelength region then major part is converted into heat, causes the rising of photovoltaic cell plate temperature, photoelectric transformation efficiency reduction, serviceable life to shorten.The usable floor area, the employing divided thin film frequency method that adopt the concentrating photovoltaic power generation method can reduce photovoltaic battery panel at double shine photovoltaic battery panel after the low frequency long wave in the sunshine is separated again, are two important directions of present photovoltaic power generation technology; For discontinuous problem round the clock, photovoltaic power generation technology itself is difficult to overcome, and mainly relies on supporting the replenishing of accumulator or energy storage power generation system (as storage station etc.), and cost is very high.
The photo-thermal power generation technology is mainly to be to utilize parabolic mirror (or Fresnel mirror) that sunshine is gathered together, and produces steam or heating fluid driveable engine (as steam turbine, Stirling-electric hybrid etc.) is generated electricity by photo-thermal conversion and heat-exchanger rig; Its advantage is that this technology can absorb full wave sunshine, can realize uninterruptable power generation round the clock by accumulation of heat.Parabolic mirror mainly is divided into slot type, tower and dish formula three major types.Wherein, the slot type mirror is that sunshine is accumulated on the line parallel with minute surface, and this technology is only carried out the one dimension tracking to sunshine, and the sun power utilization ratio is lower.Tower optically focused normally utilizes thousands of (or more) individual heliostats sunshine to be accumulated on the heat collector on high tower top, and this system's floor area is big, and the orientation of each heliostat and curved surface are all inequality, the control system complexity.Dish formula optically focused is made up of integral body rotation parabolic minute surface or multiaspect mirror usually, sunshine can be accumulated in the small size, and floor area and optically focused are more adjustable than flexibly, are the important directions of current development; Current dish formula concentrating generating system need be installed in stirling generator on the focus of dish formula mirror, and stirling generator is very heavy, and the system energy consumption when this has just increased solar tracking has greatly obviously reduced simultaneously system balancing and wind resistance.
From present technical indicator, the peak efficiencies of concentrating photovoltaic power generation and dish formula photo-thermal power generation all can reach about 30%.If can adopt the optically focused dividing method, concentrating photovoltaic power generation (utilizing high-frequency short waves) and dish formula photo-thermal power generation (utilizing the low frequency long wave) are combined, not only can realize uninterruptable power generation round the clock, and the peak efficiencies of totally generating electricity can reach about 45%; If can then can effectively reduce system energy consumption with the focal spot of optically focused from transferring to system below or ground in the air, improve the balance and the wind resistance of system.
