Description
Technical field
The present invention is multi-use solar energy collection and utilization system, belongs to the heliotechnics application.
Background technology
Solar energy is a kind of never exhausted, inexhaustible clean energy resource, yet, since low, the regional skewness of its energy density, the development cost height of technology such as the collection of solar energy, transmission and utilization, and it is big to apply difficulty.
Rotation parabolic concave face condenser (hereinafter to be referred as the concave surface condenser) is the device commonly used of solar energy collecting, it is to make parabola around the formed concaver of its main axis rotation, is coated with at the concaver concave surface that reflectorized material makes.Adopting concave surface condenser method to focus on directly utilizes heliotechnics that following several shortcoming is arranged: (1) owing to must take energy at the focus place of concave surface condenser, and can only operate out of doors, uses very inconvenient; (2) owing to must take energy at the focus place of concave surface condenser, collection area can not be made very greatly, is affected otherwise use.Because the area of single concave mirror is restricted, and the gross energy that is focused on is little, the gross energy that single assembly focuses on is low, is unfavorable for applying in the lower place of solar radiant energy metric density like this; (3) adopt and directly to be coated with reflection layer at inner concave, for example aluminize, nickel plating or silver etc., or concave surface pastes method such as reflectance coating and makes the concave surface condenser within it, because the atmospheric corrosion effect, this based reflection film can be corroded gradually and lose the optically focused effect, and the life-span is shorter.Traditional employings such as home-use level crossing are coated with metallic reflector in the one side of clear glass earlier, coat erosion shield again on coating, because this method does not realize isolating fully with atmosphere, coating is subject to aqueous vapor and corrodes, and service life is also limited; (4) function singleness, common concave surface condenser has only the solar cooker function, utilizes the time short, and comprehensive benefit is poor.If can overcome above-mentioned shortcoming, will greatly expand the application of solar energy, widen the application region of solar energy.
Aspect the transmission of solar energy, mainly adopt reflective pipe and the total reflection optical fiber bundle transmission technology lost, be transferred to the use point from the condenser focal position with the solar energy that focuses on.Utilize total reflection principle to realize that the long Distance Transmission of light beam is well-known mature technology, for example in the optical communication field, with SiO
2Be the optical fiber of main component, be operated in the near infrared band of 0.8 μ m-1.6 μ m, the minimum theoretical loss that present technology can reach is 0.16dB/km (when the light loss consumption is 0.2dB/km, being equivalent to 50% light loss consumption) at 1550nm wavelength place.Arrive in the solar radiation on ground, maximum with ultrared energy, account for 50-70%, visible light accounts for 46-30%, and ultraviolet ray only accounts for 4-0.1%, has had result of study to show, transition metal impurity such as Fe in the optical transmission medium
2+And OH
-Deng the main absorption composition that is visible light and infrared light, therefore, as long as SiO
2The main light-absorbing impurity content of material mid-infrared light and visible light is controlled, and the solar energy of high-energy-density can be realized by the optical transport technology that is similar to optical fiber.Utility model patent (ZL patent No. 02207211.X) adopts Fresnel Fresnel lens combined method and concave mirror combination with the inlet of solar light focusing to reflecting light tube, and delivers to the use point by reflecting light tube.Publication number is the patent of CN101270921, utilize anaclasis, the principle of reflection of concavees lens, convex lens, reflective surface and reflective prism, they are separately positioned on the getting in the light threeway in a light harvesting threeway, light casing coupling and the power supply device of ending that the light of solar collecting device is collected head, conduction device, the luminous energy that makes collection along the session that is provided with in operative installations.Publication number is the patent of CN1847741, disclose a kind of method that large-area solar energy burst is converged, the reflective mirror sunlight reflected converges in the beam duct through after the concavees lens refraction, in beam duct,, be transferred to the other end in the room through the continuous reflection of reflective membrane.The principle that utility model patent (the ZL patent No. 200710063059.5) adopts parabolic concentrator and the reflection of cylindrical lens reflecting surface has realized the conversion of collimated light beam energy density.Above-mentioned patent all relates to the metal film reflection of light.The transmission that the reflective shortcoming of losing Manifold technology is a light need could be sent to the use point with the light at concave surface condenser focus place by the repeatedly reflection of optical reflection film, the repeatedly reflection of reflectorized material can cause the lot of energy loss, and the once light reflection loss meeting that the high-quality aluminium film of bibliographical information, silverskin are for example arranged is greater than 2%.Therefore, this circulation way only is applicable to short-range luminous energy propagation.Utility model patent (the ZL patent No. 200420017316.3) is according to the optical-fibre communications principle, and the focus place that fibre bundle is placed on solar-energy light collector directly sends solar energy into accumulator.Application number is the patent of CN1955613 (solar fibre-optical conduction energy collection array), is made of concentrator, fibre bundle, light-receiving device and pedestal etc., also is that the sunshine that a plurality of concentrators are assembled projects on the same absorber one by one through fibre bundle.Above-mentioned two patented technologies have been utilized the total reflection principle of light in medium, though feasible, there are optical transmission loss height, shortcoming that collection efficiency is high.Because when the fibre bundle that constitutes with multifiber transmits solar energy, have only and directly be incident on the optical fiber light core, and the light that incidence angle satisfies the total reflection condition of light could pass through spread fiber, according to the transmission principle of light in medium as can be known, this part light that does not satisfy total reflection condition and be incident on fibre bundle gap location optical fiber of escaping out the most at last, the efficiency of transmission of luminous energy is lower, and is particularly all the more so when the beam condensing unit poor-performing.Application number is 200810046510.7 patent of invention " a kind of luminous energy is collected and total reflection luminous energy transmission system ", has utilized the total reflection transmission principle of light in medium, has realized the efficient
