Description
Technical field
The invention belongs to solar energy heat utilization technical field, more particularly to a kind of solar energy storage heat collector and solar energy
The technology of collecting system.
Background technology
One side mankind's energy-consuming level is improved constantly, on the other hand conventional fossil energy increasingly depleted, and conventional
The adjoint pollutant emission problem of fossil energy can not increasingly meet people for the demand of future source of energy.Solar energy is used as one kind
Inexhaustible new cleaning fuel, just increasingly obtains the attention of people, for solar energy development just
Increasingly making progress.
Solar electrical energy generation popular at present is broadly divided into two kinds of forms of photovoltaic generation and solar light-heat power-generation.Wherein
Photovoltaic generation adopts solar panel or battery thin film receives sunlight, and luminous energy is changed into electric energy directly, but is sending out
There is very big deficiency in terms of electrical efficiency and battery life.By existing technology point, solar light-heat power-generation then can be divided into slot type too
Positive energy heat generates electricity, butterfly solar electrical energy generation and tower type solar thermal-arrest generate electricity.
Trough type solar power generation is not high due to focusing ratio, and the vapor (steam) temperature of generation is relatively low, therefore generating efficiency system
About.
Butterfly solar electrical energy generation is then made up of multiple scattered small-sized concentrating generation devices, and single-machine capacity is little, same unfavorable
In the raising of overall generating efficiency.
And it is then, using numerous reflectors, large-area sunray to be gathered in one that tower type solar thermal-arrest generates electricity
On heat extractor, therefore very high temperature can be obtained, improve electricity generation system steam initial temperature, obtain higher generating efficiency.
But, for the tower-type electricity generation system of prior art, have and its development constrained with next factor：
1, system structure is complicated, initial investment is big, construction period is long；
2, in existing tower solar-thermal generating system, the energy storage material for being adopted all is fused salt, at present fused salt, which makes
Ceiling temperature is 560 degrees Celsius, and up temperature raising can cause the decomposition of fused salt, cause very big danger in itself to system and fused salt
Evil.
3, molten salt energy-storage material is easy to freeze, once freeze the injury for causing system very big；
4, molten salt energy-storage material has certain corrosivity and energy storage density is little.
In sum, current tower photo-thermal power generation, although focusing ratio is high, but the restriction of energy storage material is limited to, its
The operating temperature of heat-transfer working medium still can drop to less than 560 °, for generating efficiency has a great impact, if also walked traditional
Technology path, then the potentiality of tower photo-thermal power generation are just limited.
And a new technique " supercritical carbon dioxide generating set " is used in photo-thermal power generation, it will be following photo-thermal power generation
Outlet, supercritical CO 2 generating set has excellent characteristic, is mainly manifested in：Its power density is high, small volume, generally
The 1/20～1/30 of steam turbine, only 4 to 6 cubic metres of the equipment of 10 mw scales；Its low cost, initial outlay compare steam turbine
It is low by 30%～40%；It is lower than gas turbine by 20%；Its thermal efficiency is high, reaches as high as 55%；Its simple structure, amount of parts
It is few；Its operating temperature low (compared with gas turbine), low cost；Which belongs to external-combustion engine, it is possible to use pluralities of fuel, energy security
Property it is high；Due to the terseness of supercritical CO 2 circulation, which can be used as the bottoming cycle of combined cycle；Due to supercritical carbon dioxide
Circulation belongs to single-phase circulation (Brayton cycle), and no phase transition process does not use condenser, the quantity of the valve for being used, only
/ 10th of Rankine cycle；Conventional stainless steel material, low cost of manufacture can be used.Supercritical carbon dioxide generating set
Except small volume, it is lightweight in addition to, can also be without using water, be adapted to desert water-deficient area application, be solar light-heat power-generation
Ideal chose, when doing working medium using CO2, does not have that working medium is freezed, and without electric tracing on pipeline, construction is simple, and can
Significantly reduce cost.2011, the U.S. announced to develop a kind of new supercritical carbon dioxide Brayton cycle turbine, and which is high
The characteristic such as efficiency, pollution-free, small volume, becomes the mark post of world's power cycle generation technology, and this new nest wheel machine can be by thermoelectricity
Conversion efficiency improves up to 50% (general only three one-tenth more).
Due to the limitation of existing energy storage technology, the technology of current photo-thermal power generation is difficult supercritical carbon dioxide to be heated to
More than 700 °, and the tower system for adding energy storage of tradition is excessively complicated, transporting resistance of the supercritical carbon dioxide in system pipeline
To be very big, and can also affect application of the new technique in tower photo-thermal power generation.
So, the heat collector and efficient solar thermal collection system of novel efficient and energy energy storage are developed, for reduction
Photo-thermal power generation cost and raising power plant's reliability and popularization in future supercritical carbon dioxide solar power system all have weight
Want strategic importance.
Solar light-heat power-generation is realized into extensive industrialization, most critical still in the breakthrough of technical elements, in heat build-up
To there are technological innovation, technological break-through in mode, need once the technology of the property changed, promote out and out energy technology leather
Life.
