Description

Solar energy pipe collector

The present invention relates to a kind of solar energy conversion using device, exactly, relate to a kind of solar energy pipe collector, be used for long distance oil pipeline and substitute traditional heating station.

Solar energy is extremely abundant, and the utmost point energy to be developed again is radiated the solar energy of earth surface in four ten minutes, be equivalent to the energy consumption in 1 year in the whole world nowadays.Solar energy is a kind ofly clean, pollution-free environment not to be had the good primary energy of influence, of high grade, abundant resource, and just energy density is low, and it is subjected to territorial restrictions hardly, no matter where can utilize.In fact, the present many energy (as coal, oil, waterpower, wind-force etc.) that use of people also are indirect primary energy from solar energy.Along with social development and human civilization advance, people are acceleration tendency to the consumption of primary energy, make the primary energy that stores on the earth reduce year by year.For this reason, since the 60 to 70's, people are seeking the various novel energies of development and use always, especially solar energy has been poured into especially and " be deeply in love ", the applicant is on the basis of development tackling key problem for many years, declared the patent application that multinomial solar energy development is used, as: " a kind of translation solar energy concentrator " (application number: CN93109064.4), " a kind of step intensification numerically controlled solar boiler " application number: CN93117777.4) or the like, for the cause that solar energy promotes the well-being of mankind is done one's bit.

The purpose of this invention is to provide a kind of solar energy pipe collector, seek a new way apart from the uncultivated area development and use of petroleum pipeline and desert solar energy for long.

The present invention is achieved in that and includes support, energy transducer, speculum, copper sheathing and pad, it is characterized in that: said energy transducer has interior pipe and the outer tube made from the silicon boron glass, the outer wall of interior pipe is coated with black film, the port of interior pipe and outer tube is sealed, space between interior pipe and outer tube forms vacuum, said energy transducer is enclosed within the outside of a pipeline, said copper sheathing is housed between the inwall of pipeline outer wall and interior pipe, between said two adjacent energy transducers, said buffering spacer is housed, the said speculum of by said bracket supports is housed below said energy transducer.Said speculum can be the approximate concave curvatures of parabolic cylinder shape, cylindrical shape or polygon prism.Said energy transducer can be done into about the long tubular of 1-1.5 rice, also can make the structure that two involutory adhering and sealings of semicircle form.

In fact the present invention is exactly a pipeline that adds thermal-arrest (conversion of solar energy and come) device, the present invention is installed in the periphery of the long distance oil pipeline that passes through barren beach area, Gobi desert, desert, just can substitute the pipeline heating station and be used for, make oil wherein can grow the unobstructed conveying of distance to pipeline heating.Now, in long distance oil pipeline, for the crude oil that makes viscous transmits unimpeded, the crude oil that accounts for the 1-2% of conveying crude oil total amount to be acted as a fuel the heating station in the supply pipeline to use, because radix is big, can save this part crude oil, quantity also is appreciable.The another kind of potential use of the present invention then is to have under the wide solar energy cumulative occasion, utilize the principle (referring to patent application CN93117777.4) of step intensification numerically controlled solar boiler, lay the pipe type solar energy energy collector device of long distance, and this pipe line area is divided into the endothermic tube that plurality of sections has different temperature rises, utilize the promotion of numerical control circulating pump, when heat absorption working medium is circulated in each pipeline, absorption rises heat absorption working medium temperature by the solar energy of energy transducer inwall absorption, because each pipeline is connected, heat absorption working medium all rises by temperature in each segment pipe, by a plurality of series connection, just can obtain our needed temperature rise, the heat absorption working medium of this moment or carry out heat exchange by heat exchanger and heat-transfer working medium, the solar heat that heat absorption working medium is absorbed passes to heat-transfer working medium, enter boiler output energy by heat-transfer working medium, perhaps directly utilize the acting of heat absorption working medium and the output energy.This it goes without doing pursuit movement, the tubular type energy-collecting device that just can export grade heat energy in the higher temperature not only is suitable for desert or uncultivated area, sandy beach, Gobi desert, for example domestic northwest and California, USA, area such as continent, Arizona utilizes, also can use this device, hot water, heat energy or other heats are provided in the both sides of highway.

Fig. 1 is that structure of the present invention is formed schematic diagram.

Fig. 2 is a structure vertical cross-section schematic diagram of the present invention.

Referring to Fig. 1, Fig. 2, the 1st, pipeline, when the present invention was applied to the petroleum pipeline line, it was exactly an oil pipeline; When being applied to the solar boiler of step intensification, it is exactly the endothermic tube that is loaded with heat absorption working medium.The 3rd, install in pipeline 1 periphery, the nestable glass round tube energy transducer made from the silicon boron glass of circular bilayer, port sealing between its inside and outside two-layer pipe 31,32, make its space form vacuum, the outer wall of pipe 31 is used vacuum plating black film and is handled in it, so that can absorb solar energy to greatest extent and reduce the thermal loss that produces because of cross-ventilation, radiation.These energy transducers should be made 1～1.5 meter long tubular, also can make two structures that the involutory adhering and sealing of semicircle forms of above-mentioned length, so that install and maintenance.The 2nd, with the heat transfer medium that copper sheathing is made, it has certain elasticity, is close to the outer wall of pipeline 1 and the inwall of energy transducer 3, makes heat energy pass to pipeline 1 from energy transducer 3.Between adjacent two energy transducers 3, be installed on buffering spacer 5, be equipped with below energy transducer 3 by speculum 4 stent support, that have gathering solar energy effect, this speculum 4 can be the approximate concave curvatures shape of parabolic cylinder shape, cylindrical shape or polygon prism; In order to reduce manufacturing cost, also can adopt flat speculum to be installed in below the below and the left and right sides of energy transducer 3 sometimes, to improve the energy density of solar energy on the energy transducer surface.Because the annulus speculum has the characteristic on the anchor ring of the light focusing to two of different incidence angles degree/annular radii, if energy transducer 3 is installed to the tangent position of focal plane circular arc of annular speculum, just can make the sun on high during any position, the sunlight that shines speculum 4 can both be reflected to the surface of energy transducer 3, both improved the mean energy density on energy transducer 3 surfaces, the pursuit movement device of speculum need be installed again, simple in structure, reduce cost.

According to applicant's measuring and calculating, if use the present invention, set up solar energy pipe collector in Beijing-Tianjin highway both sides, the heat energy that can collect in 1 year can reach 2.37 * 10 ¹²Kilocalorie, these heat energy can make the annual quota of expenditure coal 3.93 * 10 that reduces ⁵The ton, in 200 yuan in coal per ton, these coals overbalance 100,000,000 yuan.Though, country at present also impossibleization expense huge fund set up the thermal-arrest pipeline in the highway both sides, but utilize the development of cause along with solar energy, about the reduction of device cost and the exhaustion day by day of earth resource, this once invest huge, but on " project sunshine " that can produce effects all the year round can put on the agenda sooner or later.
