Description
Technical field
The utility model relates to solar energy optical-thermal conversion equipments, more particularly, to a kind of loop type bifocal slot type solar energy
Collecting system.
Background technique
Trough type solar power generation is one of important directions of solar energy thermal-power-generating.Currently, solar energy resources state abundant
Family and area, such as southern Spain, California, USA, Dubai, trough type solar power generation project development are rapid.China is to the sun
The hot power generation project of energy is attached great importance to, and in recent years, the multinomial supportive policy of successively issue, such as: National Development and Reform Committee, Bureau of Energy issue
" production of energy and consumption revolution strategic (2016-2030) " (hair changes basis [2016] 2795), propose the non-fossil energy across
It develops more action, to the year two thousand thirty, the specific gravity that non-fossil energy generated energy accounts for whole generated energy strives reaching 50%.Preresearch estimates,
China possesses 1700 kilowatt hours of available year DNI >/m2About 940,000 km of soil2, it is mainly distributed on the Inner Mongol, Tibet, blueness
Sea, Xinjiang, Gansu province.The resources supplIes of China's photo-thermal power generation are as follows: the annual electricity generating capacity of every 100,000 square kilometres of areas: 54000
× 108 kilowatt hours.It using hourage is 3500 to calculate by configuration heat reservoir unit, 100,000 square kilometres of soils can install appearance
About 1,500,000,000 kilowatts of amount.
Although photo-thermal power generation has fine prospect, mature technology, the road improved efficiency are full of challenge.Domestic aspect,
The rate for incorporation into the power network of photovoltaic power generation down to 0.55 yuan/kilowatt hour, report according to IRENA " 2017 renewable energy cost " by international aspect
It accuses, photo-thermal power generation levelized cost in 2017 is 0.22 dollar/kilowatt hour, the year two thousand twenty and photo-thermal bid electricity price generally reaches before
6-10 cents/kilowatt hour, the estimated the year two thousand twenty LCOE of IEA is 10 cents/kilowatt hour, and U.S. Department of Energy (USDOE) is 2025 expected
LCOE is 5-7 cents/kilowatt hour.
For the current slot type photo-thermal power generation benefit in China, by taking 100MW slot type power generation project as an example, project static investment
About 25000 to 30000 yuan/kilowatt of cost per kilowatt, project investment payoff period are about (the above project investment income in 13.96
Analysis, which is built upon National Development and Reform Commission and puts into effect " notice about solar energy thermal-power-generating mark post rate for incorporation into the power network policy " and send out, changes valence
Lattice [2016] 1881 --- 1.15 yuan/kilowatt hour).Investment payback time is too long, for investor, solar light-heat power-generation
Such as chicken ribs, tastele when eaten but a pity to throw away.The year two thousand twenty is pointed out in National Energy Board " solar energy develops " 13 " planning ",
Installation reaches 5,000,000 kilowatts, and cost of electricity-generating drops to 0.8 yuan/kilowatt hour.It can be seen that development pressure is heavy.
The system that groove type solar collecting system under current techniques generallys use American-European sizing, generally by a paraboloid
Reflective mirror and the evacuated collector tube composition (our referred to herein as single focal line list thermal-arrest casts) on paraboloid focal length, exist
The problems such as in the form of a single, application mode is limited to, photoelectric conversion efficiency is not high.Solar energy resources abundant area in China's collects mostly
In the ground such as Xinjiang, Qinghai, Inner Mongol, Tibet more than 40 latitudes, this list focal line list thermal-arrest cast heat collector is in high latitude
The solar irradiation in area is influenced very greatly by latitude, and collecting efficiency is lower.By taking Turfan as an example, the horizontal plane sun in June is straight
Penetrating radiation monthly average day irradiation is 14.423 units: MJ/(m2.d), and inclination angle be equal to local latitude inclined surface on the sun
Global radiation monthly average day irradiation is 20.352 units: MJ/(m2.d).Well known, groove profile parabolic reflector is according to its daylighting
Mode is divided into East and West direction and two kinds of north-south placement form.When north-south is placed, if heat collector is made inclining for certain angle
Tiltedly, light gathering efficiency is cosine function, and when tilt angle reaches local latitude, effect is best, and light gathering efficiency can be improved 30%；If
It then can be improved 35% using dual-axis tracking system light gathering efficiency.Therefore, a kind of novel heat collector is developed, with opening suitable China
New equipment, the new opplication scheme of reason feature are the task of top priority.
It is documented that once having heat collector axis meridian line with certain inclination angle (less than 8 degree inclination angles) placement, by east orientation
The west tracking sun, but practical application is not obtained, only exist in conceptual design or experimental study stage；Groove type heat collector also has using double
The experiment of axis tracking, the double-axis tracking mode of this list focal line list thermal-arrest cast are considered economically seeing infeasible.Analysis
The reason of above-mentioned test, failure, is: above two to test the single focal line list thermal-arrest cast thermal-arrest being based under current techniques
No matter device, and defect of single focal line list thermal-arrest cast heat collector in structure, do not conformed to using inclined design or double-axis tracking
It is suitable.Such as single focal line list thermal-arrest cast heat collector is combined when being placed using inclination angle, length is too long, certainly will cause pillar that must build
Too high, only by taking 100 meters long of heat collector combination as an example, when inclination angle reaches 45 degree, strut height is up to more than 70 rice, it is clear that no
Reality；And it is swung as distinguishing son using the oil guide pipe at both ends when double-axis tracking also unrealistic.How to design one kind and meets China
High latitude geographical environment not only with slant setting but also can be that this is practical with the novel slot solar thermal collection system of double-axis tracking
Novel purpose.
