Description

A kind of disc type solar energy collecting system

Technical field

The present invention relates to a kind of disc type solar energy collecting system, be mainly used in various industrial process, commercial and civil buildings heat supply, air conditioner refrigerating reaches aspects such as generating.

Background technology

In tower electricity generation system, adopt the minute surface field of double-axis tracking usually, promptly so-called heliostat is with the concentrated receiving system that is arranged in tower center tip position that focuses on of light.This receiving system utilizes the entrained heat generation steam of heat-conducting medium (conduction oil or fuse salt) to come the generating of pushing turbine group.Except the heat conduction, heat-conducting medium also provides the energy memory function.The slot type system uses parabola or U type concentrator that sunray is focused on along the focal line of receiver, places receiving tube on focal line, only needs uniaxiality tracking.Heated medium (heat-conducting medium or water/steam) carries the heat energy that is collected, and drives the Turbo-generator Set generating thereby produce steam by steam generator.

Dish formula focusing system comprises the point focusing harvester that a shape is similar to satellite earth antenna usually, and a receiving system also has a heat engine/generator that is positioned on the concentrator focal position, and engine is generally Stirling-electric hybrid.With regard to dish formula condenser system, its reflecting surface is obtained by the parabola rotation usually.The advantage of dish formula condenser system is: by the solar motion track is followed the tracks of, make incident light vertical incidence always.Owing to be point focusing, thereby focus on than high, can obtain very high temperature, conversion efficiency is the highest in three kinds of types of focusing.The shortcoming of dish formula condenser system is that focus changes along with sun's motion, because receiver at the focus place, therefore will be not easy to solar thermal utilization along with the mobile and same moved further of focus.

This characteristic is brought a series of problem: at first, the physical dimension of receiving system will be restricted.Because oversize will certainly the causing sunlight of receiver blocked, reduce the capture area of condenser, reduce collecting efficiency.Secondly, the weight of receiving system also must strictly be controlled, because if this installation weight is overweight, certainly will greatly increase the burden of drive system.The 3rd, because the position of receiving system is unfixing, various pipelines connect the quite difficulty that becomes, and are unfavorable for forming array architecture, therefore also just are not suitable for the large-scale industrialization solar thermal utilization.At last, same because the position of receiving system is fixing, so being delivered to other place, the very difficult energy that heat collector is collected is used.

There is the cosine effect in the light collecting speculum (for example heliostat in the tower system) that various focuses are fixing though its focus is fixed.And dish formula condenser, though there is not the cosine effect, its focus changes along with sun's motion.In order to address this problem, make the fixed-site of receiving system, researchers have proposed many different solutions, comprise mirror surface is designed to two-way variable curvature, use the high order curved reflector, adopt summer and the different condenser in two sides in winter, whole condenser is around focussing movement, utilizes set screw that scheme such as is regulated in the curvature of condenser and the elevation angle in addition.These schemes have all obtained effect preferably more or less, but also come with some shortcomings simultaneously.For example application number is 200910132985.2, and name is called the patent application of " the dish formula of adjustable focus ratio focuses device ", and its heat dump is spherical, and light is only vertical with the ball surface at the normal place of ball, has influenced the assimilation effect to solar energy.

Summary of the invention

The objective of the invention is to overcome the weak point of original technology, and provide a kind of novel dish formula beam condensing unit, keep its condenser constantly perpendicular to the characteristic of incident sunshine, overcome the defective that its focus changes with solar motion simultaneously, and do not have the cosine effect.

The present invention solves the problems of the technologies described above the technical scheme that is adopted: this disc type solar energy collecting system is made up of following major part:

Solar collecting device is used for the collection of sunshine, is made up of dish formula condenser.This apparatus surface is shaped as the paraboloid of revolution, and the surface reflection material can be selected the rafifinal through anodized for use, or other reflectorized material.

The heat absorption device is made of metal, and its shape is good with the metal helical endless tube.To the requirement of this device is that (promptly not moving with the sun) must be fixed in its position, and the surface of this device scribbles coating for selective absorption.

Autotracker is used to drive dish formula condenser the solar motion track is carried out double-axis tracking, guarantees condenser constantly perpendicular to the incident sunshine, reaching the highest receiving efficiency, and is provided with the light path regulator autotracker.

Convex surface (or concave surface) speculum will become a parallel ray beam and change its direction through the light that converges after the reflection of dish formula condenser.

Light path regulator is used for the adjusting of light path, mainly is made up of plane mirror.

Mounting system is used to support entire equipment, comprises solar collecting device, autotracker, light path regulator and spirality endothermic tube etc.

The said structure design has reached purpose of the present invention.

Autotracker is to realize double-axis tracking by the azimuth of the sun and elevation angle are followed the tracks of respectively in the foregoing invention, and dish formula condenser is under the control of solar automatic tracking system, and its primary optical axis remains parallel with the incident sunshine.The sunshine of parallel incident is after the reflection of dish formula condenser, and its entrained concentration of energy is on the focus of the paraboloid of revolution.

Elevation angle-azimuth follows the tracks of and is called horizontal system of coordinates double-axis tracking system again, and in this system, azimuth axis is perpendicular to ground level, and pitch axis then is parallel to ground level.Condenser rotates around azimuth axis and changes the azimuth during work, rotates around pitch axis to change elevation angle, makes condenser vertical with sunray.From motion tracking the time, the intersection point of azimuth axis and pitch axis is fixed, and focus then changes along with sun's motion, and primary optical axis is to connect this straight line of 2.

As can be seen, if receiving system is placed near the focus, then receiving system will move along with moving of focus, has analyzed above, and there are many defectives in such structure, thereby is not suitable for employing.Our design object is, the first, and the position of receiving system must be fixed; The second, the support of dish formula condenser must be fixed, and can not move along with moving of the sun; The 3rd, do not allow the appearance of cosine effect.In order to reach above target, we are installed in convex reflecting mirror in light path near the focus of dish formula condenser, and the primary optical axis of the optical axis of convex reflecting mirror and dish formula condenser coincides.Distance between convex reflecting mirror and the dish formula condenser is changeless, and the focal length that equals dish formula condenser deducts the focal length of convex reflecting mirror.In other words, the virtual focus of convex reflecting mirror overlaps with the focus of dish formula condenser.At this moment, the only a branch of directional light that reflects through convex reflecting mirror.If we adopt concave mirror in light path, then the distance between concave mirror and the dish formula condenser also is changeless, and the focal length that equals dish formula condenser adds the focal length of concave mirror.In other words, the focus of concave mirror overlaps with the focus of dish formula condenser.At this moment, the light that reflects through concave mirror also is a branch of directional light.Adopt convex reflecting mirror still is that concave mirror can decide according to actual conditions actually, does not have essential distinction on principle.Because the parallel direction of light of returning through convex surface (or concave surface) mirror reflects is the major axes orientation along dish formula condenser, therefore, need open a circular hole in the center of dish formula condenser.The diameter of this circular hole is that condition decides hot spot is not had any blocking.Like this, behind incident sunlight process dish formula condenser and convex surface (or concave surface) speculum two secondary reflections, pass the circular hole at dish formula condenser center along the original incidence angle of sunlight with the form of a branch of directional light.At the intersection point place of the pivot and the dish formula condenser primary optical axis of system, light path regulator is installed, adjuster is made up of plane mirror.Along with one day motion of the sun, by the light path regulator autotracker angle of plane mirror is regulated, to reach following purpose: no matter the angle of light degree of returning through convex surface (or concave surface) mirror reflects how, the plane mirror light reflected all arrives the spirality endothermic tube that is positioned at the support below along direction perpendicular to the ground.Just because of we are arranged in the pivot place of whole system with light path regulator, have guaranteed that just the position of spirality endothermic tube can immobilize, and be not subjected to the influence of incident sunshine angle fully.Can think like this that we move by plane mirror, have overcome the defective that dish formula focusing system focus changes with solar motion.Moreover, this device has also been avoided the cosine effect.Because the control of the angle of plane mirror and the angle of whole dish formula condenser are controlled and are had direct relatedly, can be realized by same scm software.The heat absorption device can be made up of the helix tube that the metal/alloy material is made, and working medium circulates in the middle of helix tube under the effect of circulating pump, and constantly absorbs heat, is deposited in the middle of the energy storing device through the heating back.The metal/alloy material that is adopted must have very high thermal conductivity factor, be subjected to the light beam irradiates of high order focusing after, can promptly heat be passed to inner working medium.The metal/alloy helix tube beyond the effect of heating, also play guiding, and the area of the size of heat absorption device and dish formula condenser has direct relation except playing circulation.System frame need play following effect: the total weight that a) supports dish formula condenser; B) carrying is used for the rotating mechanism of dish formula condenser from motion tracking; C) provide the support of necessity and enough spaces for light path regulator; D) the spirality endothermic tube is played fixation.In order to realize above several requirements, can adopt cylindrical stent perpendicular to ground.Native system has two cover robot brain systems, and a cover is used for controlling dish formula condenser, and an other cover is used for controlling light path regulator, and their realization all leans on the mounting system structure to support, therefore, the design of support is most important.The present invention has kept all advantages of dish formula focusing system, has overcome the shortcoming that its focus changes with solar motion simultaneously, and compact conformation is convenient to array, is particularly suitable for various industrial process, commercial and civil buildings heat supply, and air conditioner refrigerating, and generating waits application.
