Abstract
Multi-mode tower type solar energy thermal power generation device of the present invention uses special cermacis solar receiver, substitutes the heat transfer heat-storage medium such as conduction oil or fused salt with " drift sand ", and the sensible heat carried by drift sand and hyperthermia radiation realize the generating of supercritical carbon dioxide Bretton heat；On the basis of innovation fused salt heat-storage technology, achieve and the technology complementation such as organic Lang Ken heat generating, LiBr-Air-conditioner, biomass energy, feel free to try in number, expansion range when reducing cooling water, reduction cost, extending generating, establish technical foundation for final replacement fossil energy generating.This device belongs to solar energy thermal-power-generating technical field.
Description
Technical field
Multi-mode tower type solar energy thermal power generation device of the present invention takes into account different heat transfer mediums, uses innovation
Solar receiver, keep fused salt heat accumulation technical foundation on, add and biological energy complementary technology,
Reduce cooling water, when reducing cost, prolongation generating, in number, expansion range, all have bigger technology to dash forward
Broken.This device belongs to solar energy thermal-power-generating technical field.
Background technology
The most prominent advantage of the hot generation technology of Brayton cycle is that system thermal photoelectric transformation efficiency is high, mainly adopts
It is power working medium with air, helium, carbon dioxide gas, and is carried by fuel oil, combustion gas, nuclear energy, solar energy
Run for high temperature heat.It is obvious that this technology not only fuel gas generation, nuclear power field and at solar heat
Power field also will have good application prospect.United States Patent (USP) US7685820 " supercritical carbon dioxide optically focused
Solar power system device " detail by fused salt heat exchanging and use supercritical carbon dioxide gas as dynamic
The device structure of power working medium, this patent is rankine cycle to be steamed on the basis of tradition solar molten salt heat storage and exchange
The hot generation technology of vapour simply replaces with supercritical Brayton cycle dynamic power, the Chinese patent families of this patent
It is 200710306179.3.U.S. Patent application US2012216536A1 identical with this patent then changes double
Tank heat accumulation is single tank heat accumulation.United States Patent (USP) US4479353A utilizes solid particle heat accumulation and heat transfer to realize Lang Ken steaming
Vapour cycle generates electricity, and same is patent US8109265B1, it is intended to obtain high temperature air by solid particle
Heat exchange drives Brayton cycle thermal electric generator, with this patent similarly Chinese patent again
" 200910090284.7 solid sphere flux heat absorber for solar thermal power generation ", its defect is the solid particle of customization
Becoming freely falling body to decline in light radiation environment, thermal absorptivity is the lowest.In fact, relatively early propose supercritical
What Brayton cycle power technology was applied in solar energy thermal-power-generating field is polytechnical university of BeiJing, China, next to that
First, the China using Brayton cycle principle to set up in development zone, Nanjing of China Jiangning in 2005 is tower too
Sun can thermal power station.This power station makees heat-transfer working medium by solar energy cavity type receptor with air, is aided with sky
So gas and small size gas turbine take the lead in achieving the heat generating dress utilizing solar energy and Brayton cycle technology to combine
Putting, owing to cavity-type solar receptor entrance is the least, intake air temperature is difficult to supporting with combustion gas cause the failure of an experiment.
" Flos Tulipae Gesnerianae " small-sized tower type solar energy thermal power generation pilot project that Israel and Australia implement really should
The continuation of technology.Chinese patent 201210418099.8 " uses the tower sun of integration of drift sand heat accumulation heat transfer
Can thermal electric generator " the pipe type solar energy receptor that selects exists with tradition live (open) steam and fused-salt medium receptor
Big difference is there is no in structure, the most identical with WO2013006630A2 patent.The common defects that they exist
Be solar receiver all be use metal comb directly absorb heat, have class with traditional fused salt solar heat absorber
Like part.The inherent shortcoming of tower type solar energy thermal power generation is wind load resistant poor performance, the wind load of heliostat and face
Amassing and be directly proportional, the biggest wind load of area is the biggest, and therefore heliostat shake is the most serious, thus directly results in the sun
Can decline to a great extent by receptor surface energy flux density, heat-transfer medium temperature also can occur fluctuation therewith.Therefore,
For the inherent shortcoming overcoming tower type solar energy thermal power generation device to exist, it is necessary to innovation solar receiver, only
Maximize favourable factors and minimize unfavourable ones, just can give full play to the advantage that tower type solar focusing ratio is high, temperature is high, for using efficiency more
High Brayton cycle dynamic power pattern lays the foundation.
Summary of the invention
The technical problem to be solved is to select multi-mode for tower type solar energy thermal power generation device
Dynamic power technology, use brand-new solar receiver and heated structure thereof and heat-transfer working medium, by not
Complementation and thermal energy step with technology utilize and realize light, heat, electricity utilization ratio maximization.The present invention is taked
Technical measures mainly have four, be first to play special cermacis heat absorption capacity and the high advantage of heat conductivity,
Use multiple structure solve solar receiver absorb heat, conduct heat, the problems such as insulation of being heated；Two is to use mine-laying
Pause cycling hot generation technology, simplifies structure, reduces manufacturing cost as far as possible；Three is tower type solar generating dress
Put the organic Lang Ken thermal electric generator of configuration or LiBr-Air-conditioner unit, it is achieved thermal energy step utilizes；Four is by tower
Formula device of solar generating is complementary with biogas generating means, it is achieved solar energy and biomass utilization efficiency
Maximize.
The present invention is achieved by the following technical solutions:
1, multi-mode tower type solar energy thermal power generation device includes heliostat light-condensing array, and solar energy receives
Tower, solar receiver, metallic heat exchanging tube, catalyst converter, the insulation material of coating high temperature resistant heat insulation coating,
Power working medium, air accumulator, gas fuel boiler, dynamic power device；Drift sand, drift sand heat exchanger, stream
