Description
Technical field
The present invention relates to a kind of Blast Furnace Top Gas Recovery Turbine Unit (TRT), relate in particular to a kind of solar condensing power generation device.
Background technology
Concentrating solar photovoltaic generating can reduce the photovoltaic generation cost significantly.Along with improving constantly of new and effective concentrator cell efficient, concentrating generating system will be more and more important in the solar energy power generating field.Light-gathering optics has various ways, and main application is parabolic reflector formula point focusing system at present, and the advantage of this system is: can change more high efficiency battery; Light concentrating times is variable; Cost low (the speculum cost is low, and light concentrating times can be very high, to the demand minimizing of battery).But following shortcoming is arranged also: the one, it is higher that speculum is made required precision, local error will cause the inhomogeneous of battery surface Energy distribution, form focusing and will cause receiver to damage on the receiver surface easily, perhaps the excessive receiver that overflows of hot spot reduces generating efficiency and reduce energy output; The 2nd, large-scale parabolic reflector system generally is divided into fritter when making, be combined into complete reflecting system when installing in system.Paraboloid structure makes its assembly work very complicated, must use big machinery to help work, has increased system's mounting hardness.
This just requires original reflecting system is redesigned, to solve above potential problems.
Summary of the invention
Purpose of the present invention is to solve the problems referred to above that prior art exists, provide a kind of light distribution evenly, be easy to assemble, tracking accuracy is required not high again solar condensing power generation device.
The object of the present invention is achieved like this: a kind of solar condensing power generation device, comprise concentrator, sunlight receiver and solar automatic tracking device, solar automatic tracking device can be from the motion tracking sun so that concentrator points to the sun all the time, described concentrator is made up of at least one class plane mirror light focusing unit, class plane mirror light focusing unit is by the class planar substrates and be installed in suprabasil a plurality of plane mirror and form, each plane mirror has certain incline direction and angle respectively with respect to the class planar substrates, each plane mirror all can converge to the sunlight of incident the outer surface of sunlight receiver, and the sunlight that converges to the sunlight receiver outer surface has the shape with sunlight receiver outer surface basically identical.
The bottom surface of described class planar substrates is the plane, the installed surface that is used for the mounting plane speculum has the display of being made up of a plurality of declining lugs, and the incline direction on the inclined plane of each declining lug and angle are suitable with the incline direction and the angle of each plane mirror respectively.
Described concentrator is made up of a plurality of class plane mirror light focusing unit, a plurality of class plane mirror light focusing unit big or small identical.
Described concentrator is made up of a plurality of class plane mirror light focusing unit, the varying in size of a plurality of class plane mirror light focusing unit.
Described a plurality of class plane mirror light focusing unit is symmetrical in the axis of sunlight receiver and arranges.
Solar condensing power generation device of the present invention is made up of at least one class plane mirror light focusing unit owing to its concentrator, class plane mirror light focusing unit is combined by a plurality of plane mirrors of class planar substrates and mounted thereto again, each plane mirror is radiated at the hot spot that the sunlight of incident pools with receiver area basically identical on the receiver, the onesize hot spot of a plurality of such small reflector reflections overlaps on receiver, thereby has improved light concentrating times.The beam intensity ratio that converges on the receiver of each plane mirror is more even like this, and, when the hot spot that is converged by a plurality of such plane mirrors was overlapping on receiver, the surface error of individual mirror was very little to light distribution inhomogeneities influence total on the receiver.The distance of speculum and receiver is short more, and is low more to the requirement of mirror surface precision, also low more to the required precision of tracker simultaneously.
