Abstract

PURPOSE:To provide the title device in which the light and heat collecting efficiency is improved, the use of molten salt is facilitated and generation of thermal strain is prevented by collecting solar light of high density led out by flexible optical fibers to a common heat collector by fixed mirrors disposed within a large number of channels provided radially around a heat collctors, and converting the solar light into thermal energies. CONSTITUTION:Flexible optical fibers 3 are fitted to light collectors 1 and 2 so that one end surface of each of the optical fibers 3 is positioned at a light collecting point of solar light L, and collected solar light is led out by the optical fibers 3. A large number of channels 6 are formed below the ground surface radially centering around the heat collector 4, and are covered with a lid member 7. Perforated holes 7a are provided at suitable positions of the lid member 7. Other ends of the optical fibers are collectively inserted into the perforated holes 7a, and fixed mirrors 8 inclined at an angle of 45 deg. are disposed below the holes 7a. Thus, the light from each optical fiber 3 is reflected toward the heat collector 4. By this arrangement, sun tracking devices of respective light collectors do not reqire high accuracy and may be simple in construction.

大きな熱エネルギーを取り出すための太陽光集光集熱装
置に関する。[Detailed description of the invention] This invention is a solar light concentrator for efficiently concentrating sunlight and extracting a large amount of thermal energy in a system that utilizes the sun's thermal energy such as solar thermal power generation. Regarding a heat collection device.

別される。4. Systems that utilize the sun's thermal energy, especially solar power generation plants that require high-density thermal energy, are broadly divided into ``concentrated systems'' and ``distributed systems.''

プラインによって地上へ導いて、蓄熱器を介して蒸気を
タービン発電機に供給する方式である。The conventional concentration method, also known as the tower concentrating method, involves arranging a large number of hemi-ostats (plane mirrors) on a large flat site, installing a tower in the center of the group of hemi-ostats, and installing a tower at the top of the tower to collect heat. The reflected light from each heliostat is concentrated in a vessel, which converts sunlight into thermal energy, heats the medium (water or molten salt, etc.) in the heat collection tube, and guides it to the ground via a pipeline. This method supplies steam to a turbine generator via a heat storage device.

にも多大な労力と経費を要する。However, this tower condensing method requires a high-precision tracking device for each heliostat in order to concentrate sunlight in one place from a wide area, and the positional relationship between each heliostat and the tower is slightly different. Therefore, each tracking device must be made to move differently, making the tracking mechanism and its control device complicated and expensive, and its maintenance requires a great deal of effort and expense.

しかも、全てのへりオスタットの鏡面に略垂直に太陽光
を入射させるようにはできないので、鏡の有効利用率が
あまり良くない。Moreover, since it is not possible to make sunlight incident approximately perpendicularly to the mirror surfaces of all heliostats, the effective utilization rate of the mirrors is not very good.

また、タワーの頂部に集熱器や蒸気ドラム等の重量物を
地震や強風にも耐えるように支持しなければならないの
で、大型で頑丈なタワー構造を必要とし、建設コストが
高くなる。しかも、風等によりタワーが揺動すると追尾
が困難になるという問題もある。Furthermore, heavy objects such as heat collectors and steam drums must be supported at the top of the tower to withstand earthquakes and strong winds, which requires a large and sturdy tower structure, which increases construction costs. Moreover, there is also the problem that tracking becomes difficult when the tower swings due to wind or the like.

さらに、集熱器を断熱して曇天時や夜間等の保温を計る
ことが困難であり、且つ高温の蒸気を長いパイプライン
で地上へ導く間に多量の熱損失を生じるため、太陽エネ
ルギーの利用効率が低くなってしまう問題がある。Furthermore, it is difficult to insulate heat collectors to keep them warm on cloudy days or at night, and a large amount of heat is lost while leading high-temperature steam to the ground through long pipelines, making it difficult to use solar energy. There is a problem of low efficiency.

この方式では、太陽の追尾精度は集中方式に比べて低く
てよく、しかも各集光装置を全て同じ姿勢で動かせばよ
いので、追尾装置が簡単で安価になるし、タワーを必要
としないので建設コストも安くて済む利点がある。With this method, the tracking accuracy of the sun is lower than that of the concentrated method, and since all the concentrators need to be moved in the same position, the tracking device is simple and inexpensive, and there is no need for a tower. It has the advantage of being low cost.

しかしながら、集光倍率が１０〜１００倍程度と低いた
め、高温が得られにくい。However, since the light collection magnification is as low as about 10 to 100 times, it is difficult to obtain a high temperature.

そこで、前記の集中方式と分散方式の特徴を取り入れた
曲面集光方式による太陽熱発電プラントが香川県仁尾町
に建設されている。Therefore, a solar thermal power generation plant using a curved surface concentrating method that incorporates the characteristics of the above-mentioned concentrated method and distributed method is being constructed in Nio Town, Kagawa Prefecture.

ギーに変換し。In this method, a large number of flat reflecting mirrors are distributed and installed in multiple units, and each unit has a curved mirror with a heat collecting tube at its focal point, which is placed facing each other. The light is reflected toward a curved mirror, and the reflected light from the curved mirror is focused on a heat collection tube. There, sunlight is converted into thermal energy.

れだけ安くはなるが、各平面鏡の追尾は、タワー集光方
式と同様に高精度を要する。According to this method, it is possible to obtain steam at the same high temperature and pressure as the tower condensing method, so the power generation capacity is also about the same, and since no tower is required, the construction cost is lower. Tracking of each plane mirror requires high precision, similar to the tower condensing method.

また、この方式によっても、集熱器における保温が困難
なこと及びパイプラインにおける熱損失の問題は解決さ

温度が２００℃以下に低下すると凝固してしまうため、

If the temperature drops below 200℃, it will solidify, so
In each of the conventional methods described above, the heat collector (
It was difficult to keep heat collecting pipes and pipelines at 200°C or higher at all times, so they could not be used.

さらに、従来の集中方式や曲面集光方式では。Furthermore, in the conventional focusing method and curved surface focusing method.

集熱器又は集熱管の全面に均等に太陽光を集光するのは
困難であり、集光むらにより表面の各部に大きな温度差

も問題があった。It is difficult to concentrate sunlight evenly over the entire surface of a heat collector or heat collection tube, and uneven light concentration causes large temperature differences on different parts of the surface, which can lead to damage due to thermal distortion, which reduces durability. But there was a problem.

It is an object of the present invention to provide a solar light condensing and heat concentrating device that is easy to install, can prevent the occurrence of thermal distortion, and can be constructed at relatively low cost.

ある。Mr. Tsuji Therefore, the solar light concentrating heat collecting device according to the present invention is a movable reflector equipped with a tracking device for tracking the sun, similar to the light concentrating device in the conventional distributed type solar heat collector described above. Sunlight is concentrated by multiple concentrators made of mirrors or lenses, and then guided as light through flexible optical fibers. Fixed mirrors arranged in a number of radial channels collect the heat toward a common collector, where it is converted into thermal energy.

ヌー施二四 以下、添付図面を参照してこの発明の詳細な説明する。Nu Shi 24 Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

5.23 and the tracking device 14. The optical axis of the parabolic mirror 11 or Fresnel lens 21 (
(indicated by a dashed-dotted line) is tracked so that it points approximately toward the sun, but the tracking accuracy does not need to be that high.

この集光器１及び２は、それぞれ太陽光線りの集光点に

する。Each of the light concentrators 1 and 2 has a flexible optical fiber (B) attached so that one end face thereof is located at the condensing point of sunlight, and the collected sunlight is led out through the fiber 3.

。As shown in Fig. 2, a large number of such condensers 1 and 2 (only one of them may be used) are arranged in blocks (seven in the illustrated example), and a large number of condensers 1 and 2 are arranged in the central part of the whole. A heat collector 4 is covered with a heat insulating wall 5 and installed underground or semi-underground.

そして、この集熱器４を中心として放射状に多数のチャ
ンネル６を地表面（第１図にＳで示す）下に形成し、蓋
体７で覆っている。A large number of channels 6 are formed radially below the earth's surface (indicated by S in FIG. 1) around this heat collector 4, and are covered with a lid 7.

ミラー８で略水平に集熱器４に向けて反射させる。A through hole 7a is provided at an appropriate position on the lid 7 of each channel 6,
The other ends of the optical fibers 3, one end of which is connected to a plurality of concentrators 1 or 2 constituting one block, are inserted into one through hole 7a, and a 45° angle A tilted and fixed mirror 8 is disposed to radiate high-density light substantially vertically from the end face of each optical fiber B, and the fixed mirror 8 reflects it substantially horizontally toward the heat collector 4.

タービン発電機１０に供給して発電する。Therefore, it is possible to collect high-density sunlight almost uniformly around the outer circumference of the heat collector 4 through each channel 6, convert it into thermal energy, and introduce the heat collecting medium (water (or molten salt) W is used to generate high-temperature, high-pressure steam (2), which is supplied to the turbine generator 10 shown in FIG. 2 through a short pipe 9b to generate electricity.

できるので、蓄熱器の役目を兼ねることができる。In this case, high-temperature, high-pressure steam may be supplied to the turbine generator via a heat storage device, but since the heat collector 4 itself is installed underground and covered by a heat insulating wall 5, heat retention is good. Furthermore, since a heat storage material can be placed inside the heat collector 4, it can also serve as a heat storage.

円周方向の異なる位置を照射するようにしてもよい。In the example shown in Figure 1, the depth of the channel 6 is set to two levels, and the sunlight collected by the two blocks of collectors passes through a part of the common channel and is directed upward and downward to the collectors. I am trying to irradiate different positions, but this is done in 3 different locations.
There may be more than one stage, or there may be only one stage, and all different positions in the circumferential direction of the heat collector may be irradiated.

It may be formed by embedding a U-shaped groove block or a pipe material made of metal or synthetic resin.

集熱器４としては、用途に応じて、細いＵ字状のパイプ

。(3) The transmission loss of optical energy through optical fibers is extremely small, but the length of the optical fibers used can be shortened.
Most of the light energy is transmitted directly to the heat collector through the spatial light path secured by the channel, and the heat collector can be installed in one place above ground or underground, so it can be easily connected to thermal energy utilization devices such as turbine generators. Piping can be made extremely short and energy loss can be significantly reduced.

The use of molten salt also eliminates the risk of solidification.

（７）チャンネルを地表面丁番こ形成すれば、チャンネ
ル内の温度変化を少なくすると共に、風やもや等の影響
