Abstract
The present apparatus is a kind of invention for being integrated using tower structure and improving solar energy utilization ratio, using settled date tracing system, the high power concentrator of photovoltaic cell group is realized, promote photoelectric conversion efficiency, the thermal energy of generation is collected utilization by water cycle simultaneously, the energy is made to reach maximized cascade utilization.
Description
Technical field
The invention belongs to solar energy composites to utilize system, make full use of the electricity generation efficiency of photovoltaic module, improve photoelectric conversion
Rate, and photothermal conversion is utilized simultaneously, it realizes the secondary use of the energy, greatly improves the utilization rate of solar energy, while solving to supply
Electricity and heating demands.
Background technology
Now with the appearance of Bureau of Energy's photo-thermal electricity price, first photo-thermal power generation power generation project will also be completed in the end of the year 18,
But the power generation transformation efficiency of opto-thermal system does not have a distinct increment compared with for photovoltaic generation, comprehensive effectiveness 15%-18% it
Between, unique advantage is that thermmal storage cost is relatively low, can be used as peak load stations use, but there are the higher problems of construction cost, and
Photovoltaic generation passes through years development, and cost is already close to wind-powered electricity generation at present, or even approaches thermoelectricity cost, but comprehensive Solar use effect
Rate is still limited by physical characteristic without big raising, and crystal silicon generating efficiency is directly stored up at present in 14%-17% or so
Electric cost is too high, as method realizes Mass storage function.Solar energy composite utilization ratio how is improved, and can realize that solar energy is deposited
Storage, solving solar power generation discontinuity becomes the another project of current Solar use.It is international and domestic at present that there are also height
The research of times condenser system, but generating efficiency only can be improved, comprehensively utilizes high expensive, there is no fine final result energy storage problem,
The present invention utilizes tower structure, is promoting photoelectric conversion efficiency simultaneously, hot water and heating are solved the problems, such as using photothermal technique.
Technology Ways
The present invention concentrates sunlight to target point by modularization tower structure, with multi-panel heliostat, reaches high power concentrator
Effect promotes the focusing ratio of target point, and to directly improve optoelectronic transformation efficiency, superconductor is used at the cell piece back side, will be hot
Amount is transferred to behind thermal-collecting tube, is controlled altogether using water in thermal-collecting tube and does heat-conducting medium, outlet temperature is maintained at 80 degrees Celsius, Ke Yiti
Supplying hot water and heating remove outside cell piece superficial air convective heat loss, remaining energy, which can be used as, utilizes the energy, wherein battery
The direct photothermal conversion efficiency of piece reaches 30%-40%, and thermal energy heat exchange utilization rate reaches 40%, and comprehensive energy utilization rate reaches 70%
More than, and energy storage effect is carried, realize the continuous utilization of solar energy, while reducing cost.Wherein heliostat uses independent research
Automatic tracking system.Comprehensive electric generating cost is less than thermoelectricity, is the new direction of the following Solar use.
Specific implementation mode
Integral structure layout：System establishes tower type steel structure support, top using central light and heat collection tower mode, in center
Heat collector is placed, heat collector outer surface uses film electrification component, is connected with internal heat system.The settled date is placed on ground around tower
Sunlight is reflected into heat collector, and is aligned in real time by tracing system, and heat collector internal high temperature water enters heat preservation by the circulatory system
Water tank.
1. heliostat part
Heliostat use full independent research system, can when irradiation reaches threshold value automatic start up system, and by sunlight essence
Really it is reflected on thermal-arrest electric organ.Heliostat mechanical part uses biaxial system, control section to be passed using the cellular type of independent research
Sensor controls, automatic straightening, and all execution actions are all in accordance with weather and sunlight conditions adjust automatically.
2. photovoltaic cell component
Photovoltaic module uses film generating battery assembly, component to be fixed on heat collector outer surface by high-termal conductivity silica gel,
Heat collector is positioned over tower top, and the reflected beams converged by ground multi-panel heliostat reach 200 times or more of spotlight effect,
Electricity conversion is promoted to 35%.
3. collecting heat exchanger
Heat collector, which is positioned over inside tower top, uses tubular structure, is exchanged heat by water cycle, cold water is entered by pipeline
In heat collector, the heat of photovoltaic battery panel is carried out in heat-exchange system heat exchange to water, while excluding heat collector, quantity of circulating water uses
Flow valve controls, and by temperature detection, the temperature of battery panel components is kept to control at 80 degrees Celsius or less.
4. heating system
Using stainless steel thermal insulation material attemperater, heat preservation water is entered by pipeline by the high-temperature water of heat exchange in tower top
Case, provides hot water and heating uses.
