〔発明の目的〕
（産業上の利用分野）
本発明はソーラポンド（太陽池）システムにかかわり、
特に池内の水の濃度勾配の安定性を増加したソーラポン
ドにかかわるものである。[Detailed Description of the Invention] [Object of the Invention] (Field of Industrial Application) The present invention relates to a solar pond system,
This particularly concerns solar ponds which have increased the stability of the water concentration gradient within the pond.
（従来の技術）
太陽エネルギーの利用形態の一つにソーラポンドがある
。これは浅い池に太陽の光に照射して池の水を暖めよう
とするもので、その中でも高温が得られる手法として有
塩ソーラポンドが注目されるようになって来た。有塩ソ
ーラポンドは６０〜９０℃の温度が昼夜を通して得られ
るため、各種の熱源として広い用途が考えられる。(Prior Art) One of the forms of utilizing solar energy is a solar pond. This is an attempt to warm the water in a shallow pond by irradiating it with sunlight, and salted solar ponds have been attracting attention as a method of achieving high temperatures. Since salted solar ponds can provide temperatures of 60 to 90°C throughout the day and night, they can be used in a wide variety of ways as a heat source.
有塩ソーラポンド（以下単にソーラポンドと略す）の基
本的な構造を第２図（ａ）に示す。全体は浅い池となっ
ていて、その深さは数ｍ、水面の面積はシステムの規模
にもよるが数万ボ以上に及ぶものもある。同図（ｂ）の
グラフは池の深さ方向に対する水の温度（Ｔ）および密
度（ρ）の状況を示している。図から明らかなように池
の中の水は３つの層から構成されている。最下層は、水
に溶解して淡水よりも密度の大きな水溶液となる物質、
たとえば食塩などの濃い水溶液から成る蓄熱層１であり
１表層は淡水から成る上部対流層２、中間層はその間に
あって両者の間で適切な濃度勾配を有する水溶液から成
る非対流層３である。The basic structure of a salted solar pond (hereinafter simply referred to as solar pond) is shown in FIG. 2(a). The whole pond is shallow, with a depth of several meters and a water surface area of tens of thousands of ponds or more, depending on the scale of the system. The graph in FIG. 6B shows the temperature (T) and density (ρ) of water in the depth direction of the pond. As is clear from the figure, the water in the pond is composed of three layers. The bottom layer is a substance that dissolves in water to form an aqueous solution with a higher density than fresh water.
For example, the heat storage layer 1 is made of a concentrated aqueous solution such as common salt, the surface layer is an upper convective layer 2 made of fresh water, and the intermediate layer is a non-convective layer 3 made of an aqueous solution having an appropriate concentration gradient between the two.
このような構成の池に太陽光線が入射すると、池内の水
の温度は上昇し、水の密度は温度の上昇と共に小さくな
るるが、濃度による密度の増加が温度の上昇による密度
の減少に打ち勝てば、蓄熱層１の濃い水は暖まっても上
部対流層２まで上って来ることができないので、池全体
としての対流による熱の移動は妨げられ、池内は上部対
流層２で断熱された形となるので、日射条件や熱の利用
形態にもよるが、′？！ｉ熱層１は６０〜９０℃、もし
くはそれ以上の温度の熱エネルギーを蓄熱した状態とな
る。When sunlight enters a pond with this configuration, the temperature of the water in the pond rises, and the density of the water decreases as the temperature rises, but the increase in density due to concentration overcomes the decrease in density due to rise in temperature. For example, even if the dense water in the heat storage layer 1 warms up, it cannot rise up to the upper convective layer 2, so the transfer of heat through convection throughout the pond is hindered, and the inside of the pond is insulated by the upper convective layer 2. Therefore, although it depends on the solar radiation conditions and the form of heat utilization, ′? ! The i-thermal layer 1 is in a state in which thermal energy at a temperature of 60 to 90°C or higher is stored.
この熱を利用するにあたっては、通常のやり方は蓄熱層
１の高温水を温水ポンプ４で汲み出し、熱交換器５に導
いて淡水や低沸点媒体を加熱させた後蓄熱層１に戻す。To utilize this heat, the usual method is to pump high-temperature water from the heat storage layer 1 with a hot water pump 4, guide it to a heat exchanger 5 to heat fresh water or a low boiling point medium, and then return it to the heat storage layer 1.
熱交換器５で高温水から熱を受けた淡水等は、その熱エ
ネルギーを熱負荷６に供給し、循環ポンプ７で熱交換器
５へ戻る。Fresh water or the like that has received heat from the high-temperature water in the heat exchanger 5 supplies its thermal energy to the heat load 6 and returns to the heat exchanger 5 by the circulation pump 7.
（発明が解決しようとする問題点）
濃度勾配を形成するための溶質として、多くはＮａＣＱ
Ｃ食塩）が使われる。その最大の理由は他の溶質に比べ
て入手しやすく、安価だということであるが、 ＮａＣ
Ｑは水への飽和溶解度が温度にあまり関係なくほぼ一定
であるという点が、特性的に・あまり好ましくない。(Problem to be solved by the invention) NaCQ is often used as a solute to form a concentration gradient.
C table salt) is used. The main reason for this is that it is easier to obtain and cheaper than other solutes, but NaC
The characteristic of Q is that its saturation solubility in water is almost constant regardless of temperature, which is not very desirable.
なぜなら、有塩ソーラポンドの特徴は、水中に濃度勾配

り、そのためには、溶質の溶解度が温度の上昇と共に大
きくなることが理想的である。そのような溶質の場合に
は、高温の蓄熱層１から低温の上部対流層２へ溶質が拡
散することが不可能であるから、水中の濃度勾配、それ
は取りも直さず密度勾配でもある、は自然に維持され。This is because the characteristic of salted solar ponds is that they form a concentration gradient in water, increasing the density in the lower layer, and ideally, the solubility of the solute increases as the temperature rises. be. In the case of such a solute, it is impossible for the solute to diffuse from the high-temperature heat storage layer 1 to the low-temperature upper convective layer 2, so the concentration gradient in water, which is also a density gradient, is maintained naturally.
池内の水は安定な状態を保つ。しかるにＮａＣＱは温度
に対する溶解度の変化がほとんどないので。The water in the pond remains stable. However, the solubility of NaCQ hardly changes with temperature.
初期におおきな濃度勾配を形成しても１時間の経過と共
に蓄熱層１から上部対流層２へＮａＣＱが拡散して行き
、そのままではいずれ濃度勾配が崩れて、ソーラポンド
としての機能を失う可能性がある。このＮ ａ ＣＱの
有する問題点を補うためには、連続的または断続的に池
内の濃度勾配を監視し、′蓄熱層１には高濃度の溶液を
、上部対流層２には淡水を注入するなどの操作をしなけ
ればならない。Even if a large concentration gradient is initially formed, NaCQ will diffuse from the heat storage layer 1 to the upper convective layer 2 over the course of one hour, and if left as it is, the concentration gradient may eventually collapse and the solar pond may lose its function. . In order to compensate for this problem with N a CQ, the concentration gradient in the pond should be monitored continuously or intermittently, and a highly concentrated solution should be injected into the heat storage layer 1 and fresh water should be injected into the upper convective layer 2. operations such as.
そして、蓄熱層１の温度が高くなるほどＮａＣＱボンド
の安定性は低下し、濃度勾配の維持は難しくなる。Then, as the temperature of the heat storage layer 1 increases, the stability of the NaCQ bond decreases, and it becomes difficult to maintain the concentration gradient.
一方溶解度の特性に優れる溶質はとかく高価であり、経
済的に不利である。On the other hand, solutes with excellent solubility characteristics are expensive and economically disadvantageous.
本発明は、上記問題に鑑みなされたもので、その目的と

ドを提供することにある。The present invention was made in view of the above problems, and its purpose is to provide a solar pond that is inexpensive and highly self-stabilizing.
（問題点を解決するための手段） 上記目的を達成するために蓄熱層、非対流層。 (Means for solving problems) Heat storage layer, non-convection layer to achieve the above purpose.

を有することを特徴とする。In a salted solar bond consisting of an upper convection layer, heat exchange is carried out in series with a plurality of ponds containing different solutes dissolved in the heat storage layer and the non-convection layer. It is characterized by having an A position.

するものである。(Function) The present invention attempts to make use of the characteristics of the solutes by constructing a plurality of solar bonds with different heat storage temperatures using different types of solutes for each temperature level, and utilizing the heat in series. .
（実施例）
第１・図は本発明によるソーラポンの一実施例を示す構
成図である。本発明ではソーラポンドの個数を複数とし

ソーラポンドＢはＮＨ４Ｎ０１で濃度勾配を形成する。(Embodiment) Figure 1 is a configuration diagram showing an embodiment of a solar pon according to the present invention. In the present invention, a plurality of solar ponds are used, and the solution in the pond is made up of different solutes. For example, the low-temperature solar pond A forms a concentration gradient with NaCQ, and the high-temperature solar pond B forms a concentration gradient with NH4N01.
第３図はソーラポンド用の溶質として通常候補にあげら
れる物質の溶解度曲線であり、水１ｋｇ中に溶解可能な
量を示している。FIG. 3 is a solubility curve of a substance that is usually a candidate as a solute for solar ponds, and shows the amount that can be dissolved in 1 kg of water.

い替えれば、温度の低い水に溶解できる量は少ないから
、ソーラボンド内の密度勾配はいやが応でも保たれる。As mentioned above, the solubility of N a CQ is almost constant with respect to temperature, and although it increases slightly as the temperature rises, the change is very small. However, NH, No
The solubility of 3 (ammonium nitrate) and KNO2 (potassium nitrate) increases rapidly as the temperature rises. In other words, since only a small amount can be dissolved in cold water, the density gradient within SolarBond is maintained at all costs.

熱され、目的の温度に達し熱負荷６へ供給される。In the present invention, fresh water or a low-boiling point medium, etc. pressurized by the circulation pump 7 is first heated to a certain temperature by receiving heat in the low-temperature heat exchanger 5a of the low-temperature solar pond A.
It is further heated by the high-temperature heat exchanger 5b of the high-temperature solar bond B, reaches the target temperature, and is supplied to the heat load 6.

常時拡散して行くから、蓄熱層１が９０℃のような高温
になると、池の中の密度勾配は安定度が低下し、それを
維持するためには、厳重な監視と制御が必要となる。For example, if the temperature t2 required by the heat load 6 is 85℃, and the return temperature 2 from the heat load 6 is 35℃, the temperature of the heat storage layer 1 of the solar pond should be 90℃, but
In a solar pond with NaCQ as the solute as shown in Figure 2, the heat storage layer 1 contains 40
Since less than 0 g of NaCQ L will not dissolve, the density of the heat storage layer 1 cannot be increased any further, and the NaCQ in the heat storage layer 1 is constantly diffusing toward the lower temperature upper convective layer 2, so it is difficult to store heat. When layer 1 reaches high temperatures, such as 90° C., the density gradient within the pond becomes less stable and requires close monitoring and control to maintain it.
そこで、本発明では、 ＮａＣＱを用いた低温用ソーラ

には第３図から明らかなように、９０℃の水１ｋｇには
７０００ ｇも溶解し、一方大気温度に近い上部対流層
２に於いては水１ｋｇに３０００〜４０００ｇしか溶解
できないので、池の中の密度勾配は極めて安定である。Therefore, in the present invention, the temperature of the heat storage layer of the low-temperature solar pond A using NaCQ is kept at about 80°C to increase its stability, and the outlet temperature of the low-temperature heat exchanger 5a is increased.
is 75°C, and solar bond B for high temperature using solutes such as NH and NO3 is used to increase the temperature from 75°C (“t3”) to 85°C (=
The temperature will be raised to tl). As is clear from Figure 3, in the case of NH4NO3, as much as 7000 g can be dissolved in 1 kg of water at 90°C, while in the upper convective layer 2, which is close to atmospheric temperature, only 3000 to 4000 g can be dissolved in 1 kg of water. Therefore, the density gradient within the pond is extremely stable.
そして、上述の事例では、低温用熱交換器５ａおよび高
温用熱交換器５ｂにおける淡水等被加熱流体の昇温幅は
、それぞれ１．−１２：４０℃、ｔｌ−ｔ、：１０℃で
あるから、その間に被加熱流体に相変化がなければ、面
熱交換器の交換熱量はほぼ４：１である。In the above-mentioned case, the temperature increase width of the fluid to be heated such as fresh water in the low-temperature heat exchanger 5a and the high-temperature heat exchanger 5b is 1. -12: 40°C, tl-t: 10°C, so if there is no phase change in the fluid to be heated during that time, the exchange heat amount of the surface heat exchanger is approximately 4:1.
このように１本発明を用いれば溶質にかかわる費用をお
さえたうえで池内の密度勾配の安定性を向上させること
が可能となる。As described above, by using the present invention, it is possible to improve the stability of the density gradient within the pond while suppressing the cost associated with solutes.
本発明において熱負荷６は１つに限る必要はなく、要求
温度の異なる複数のものであっても良い。In the present invention, the number of heat loads 6 is not limited to one, and may be a plurality of heat loads having different required temperatures.
その場合、例えばｔ工の温度とｔ３の温度を必要とする

、系統の途中で分岐させ供給すれば良い。In that case, for example, if the temperature at t and the temperature at t3 are required, the former includes a low-temperature and high-temperature heat exchanger 5a,
Heat may be supplied in the state of tl after heat exchange with both the low temperature heat exchanger 5b, and the latter may be branched in the middle of the system and supplied with heat exchanged only with the low temperature heat exchanger 5a.
適用する溶質の種類は２種に限るものではなく、もし必
要ならば３種類以上の溶質を用いて温度レベルを３段階

As the solute for low temperature use, a solute whose saturated solubility does not change much with temperature can be used, and as the solute for high temperature use, a solute whose solubility increases as the temperature rises can be used.

It is possible to form a solar pond that is inexpensive, has a stable water density gradient in the pond even during high-temperature heat storage, and is easy to operate and manage.
