Abstract
A solar condenser comprises condenser reflecting boards, a heat collecting tube, a reflecting board support and condenser stand columns. The solar condenser is characterized in that the condenser reflecting boards comprise two parabolic reflecting boards which meet requirements of a specific formula. The solar condenser has a wind power pressure relief function and a rain water self-cleaning function. According to the solar condenser, weight of per unit length is reduced on the basis of a same condensation ratio, and therefore material and cost are saved; length of a single driving parabolic groove is increased, and therefore quantity of connection pieces, the condenser stand columns and control and tracking components is reduced; and optical condensation accuracy is effectively improved and resonance frequency is improved.
Description
Technical field
The present invention relates to a kind of solar concentrator.
Background technology
Relate to a kind of solar collector that is applicable to solar energy collecting system at US2011/0108091A1, its formation comprises collector, supports support and the tracking system that collector is moved along at least one axle tracking sun of collector.This collector comprises one or more reflecting plates, one or more solar receivers, and a supporting construction, and this structure supports for reflecting plate and solar receiver provide mechanics.Some design comprises a reflecting plate, and this reflector panel has the curvature of space.That is to say, this reflector panel has a convex shape along a direction, and has a concave along another direction.This invention on the other hand, this collector comprises a space frame supporting construction.
At US 8,039,777B2 relates to a kind of solar collector that is applicable to solar energy collecting system, although demonstrate the reflector panel of three separation, it should be noted: any amount of reflecting plate can consist of concave reflecting surface.Can adopt and connect in any suitable manner these reflecting plates.For example, in illustrated concrete device, the edge of reflector panel 310a/310b/310c is superimposed each other, and uses any suitable method jointly fixing, for example adopts securing member, bolt, bonding agent, latch, welding etc.Various concrete devices comprise a plurality of reflecting plates, and each reflecting plate is all crooked so that their one of common formations have concave surface and/or parabolic reflecting surface.In other concrete devices, each reflecting plate 310a/310b/310c is all smooth on the x-y plane in fact, but angled, thus their concave surface of common splicing or parabolic shapes.They can be slight curving along the longitudinal axis.
The weak point of above-mentioned two parts of patents is, the mirror surface arc length under identical open condition is excessive, and without letting out the wind gap, windage is large, and integral hoisting brings construction inconvenience.Said structure is applicable to the focusing surface that focusing center requires low (can appropriateness disperse) more.
Summary of the invention
For overcoming the deficiency of above-mentioned prior art, increase the parabola groove width for current popular, namely, increase sun incident area and improve optically focused than the thermal-arrest trend with reply directly-heated steam (DSS) or fuse salt heat-carrying agent (Molten-SaltHTF), the shortcoming of the wide technology of existing single parabola is, parabola groove structure and spatial volume, weight and with material also corresponding increase thereupon.Wind load, large mirror are made and the operation distortion, and resonance characteristics all can be challenged.This pair of throwing will address the above problem with burnt solar energy parabola groove technology.Have in addition the minute surface that is beneficial in rainwater automatically cleaning and conventional operation and clean advantages such as being difficult for laying dust.The invention provides a kind of mirror surface arc length short, windage is little, and solar concentrator easily is installed.
Solar concentrator of the present invention comprises concentrator reflecting plate, thermal-collecting tube, reflecting plate support and concentrator column, it is characterized in that the concentrator reflecting plate has two parabolic reflection boards, wherein:
1, the cross section parabola of first parabolic reflection board, i.e. basic parabola, coincidence formula:
2, the cross section parabola of second parabolic reflection board, namely at a distance of the parabola bunch that is a, coincidence formula:
Wherein, "-" number is over focus line gradually bunch; "+" number is progressive focal line bunch.
In above-mentioned formula, y1 is parabola 1; Y2 is parabola 2; X is the parabola horizontal coordinate value; F is for being parabolical focal length; A is two distances between parabola.Wherein f value scope is 1500-2000mm, and preferred value is 1650-1800mm; The span of a is 100-1000mm, and preferred value is 300-500mm.
The invention has the advantages that:
1, unit length loss of weight under identical optically focused ratio, save material and cost;
2, wind-force release of pressure function;
3, rainwater self-cleaning function;
4, separate related distortion, improve the optical concentration precision;
5, improve resonant frequency;
6, parabola groove length is singly driven in increase, and then reduces connector and control trace component;
7, be specially adapted to the focusing surface that focusing center requires high (should not disperse).
Description of drawings
Accompanying drawing is structural representation of the present invention, is made of concentrator reflecting plate (2), thermal-collecting tube (1), concentrator column (4) and reflecting plate support (3).
The specific embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are further described.
With reference to accompanying drawing, the present invention includes concentrator reflecting plate (2), thermal-collecting tube (1), concentrator column (4) and reflecting plate support (3), concentrator reflecting plate (2) has two parabolic reflection boards, wherein:
1, the cross section parabola of first parabolic reflection board, i.e. basic parabola, coincidence formula:
2, the cross section parabola of second parabolic reflection board, namely at a distance of the parabola bunch that is a, coincidence formula:
Wherein, "-" number is over focus line gradually bunch; "+" number is progressive focal line bunch.
In above-mentioned formula, y1 is parabola 1; Y2 is parabola 2; X is the parabola horizontal coordinate value; F is parabolical focal length; A is two distances between parabola.Wherein f value scope is 1500-2000mm, and preferred value is 1650-1800mm; The span of a is 100-1000mm, and preferred value is 300-500mm.When a is less than or equal to 100mm, there is no " wearing wind " offloading functions, inadvisable; When a is greater than or equal to 1000mm, because of solar angle, will greatly affect optical accuracy, also inadvisable.
