Description

本発明は地熱を利用した温泉地熱発電に関する。   The present invention relates to hot spring geothermal power generation using geothermal heat.

地熱エネルギがある処を削井して熱エネルギをとり、発電する地熱発電
は我が国では進んでいない。 Geothermal power generation is not progressing in Japan, where geothermal energy is excavated to generate heat energy.

日本は世界有数の地熱エネルギがある国である。日本には火山が１１０箇所あり、世界の１割を占め、しかも地熱源が都会に近いという世界でも稀な地熱発電最適国なのだが、温泉業界が源が減ることを心配して、地熱発電に反対してきた。従って、日本に地熱源があるのに、地熱発電が少ないという潜在エネルギを無駄にしてきた。
本発明はこのような課題に鑑みてなされたものであり、温泉業界の反対を受けず喜んで地熱発電に協力する発明なので、我が国の潜在エネルギを活用できる画期的な発明である。 Japan is the country with the world's leading geothermal energy. There are 110 volcanoes in Japan, accounting for 10% of the world, and even in the world where geothermal sources are close to the city. I've been against it. Therefore, even though there is a geothermal source in Japan, the potential energy that there is little geothermal power generation has been wasted.
The present invention has been made in view of such problems, and is an epoch-making invention that can utilize the potential energy of Japan because it is an invention that is willing to cooperate with geothermal power generation without receiving opposition from the hot spring industry.

前記した課題を解決する本発明は、地熱発電用の井戸を掘らず、温泉の源泉からのお湯の熱で発電し、これにより源泉の温度を下げ温泉に適する温度に下げるという一石四鳥の発明である。 The present invention that solves the above-mentioned problems is an invention of four birds with one stone that does not dig a well for geothermal power generation, but generates electricity with the heat of hot water from the hot spring source, thereby lowering the temperature of the hot spring to a temperature suitable for the hot spring. It is.

本発明により、地熱用の井戸を新たに掘削する必用がないのでローコストで発電でき、源泉の冷却をタダ又は利益を得てできる上、源泉も減らないので地熱発電に反対している温泉業者が反対しないどころか喜んで協力し、従って我が国の地熱エネルギをフルに有効利用して源泉エネルギを得ることができ一石四鳥の大きな効果がある。
図１は現在の温泉と地熱発電の関連を示す図である。図において、４は源泉である。１はマグマ、２は地球の中の地下水、３は地球の亀裂、６は源泉冷却装置、５は配管、７は温泉、８は地熱発電用井戸、９は蒸気タービン、１０は発電機、１１は発生された電力である。 According to the present invention, since there is no need to newly excavate a geothermal well, it is possible to generate power at a low cost, and the source can be cooled for free or profitable. We are willing to cooperate rather than oppose, so we can obtain the source energy by making full use of our geothermal energy, which has the great effect of four birds with one stone.
FIG. 1 is a diagram showing the relationship between current hot springs and geothermal power generation. In the figure, 4 is a source. 1 is magma, 2 is groundwater in the earth, 3 is cracks in the earth, 6 is a source cooling device, 5 is piping, 7 is hot springs, 8 is a geothermal power generation well, 9 is a steam turbine, 10 is a generator, 11 Is the generated power.

従って、温泉と地熱発電は同じ泉源を使用するので、地熱発電で源泉が減らされ、温泉運営に支障を来すとして温泉業者が地熱発電を歓迎しないため、日本には世界有数の地熱エネルギがあるのに利用されてこなかった。   Therefore, since hot springs and geothermal power generation use the same spring source, Japan has one of the world's leading geothermal energy because hot springs do not welcome geothermal power generation because hot springs are reduced because geothermal power generation reduces the source of hot springs. It has not been used.

図２は現在の温泉システムである。源泉４の温度は８０〜１００℃なので、このままでは熱くて人が入れない。そこで、冷却装置６として湯の中に冷体を浸けて温度を下げたり、枝の沢山ある笹竹１３の上まで熱湯をパイプ１２で導き笹竹１３に降り注ぐと、枝を垂れ落ちる１４間に温度が下がり、溜温１５の温度は４２℃程度の人が入れる温度になるので、これをパイプ１６を通じて温泉部７に導く方法をとっている。   Figure 2 shows the current hot spring system. Since the temperature of the source 4 is 80 to 100 ° C., it is too hot for people to enter. Therefore, as the cooling device 6, the temperature is lowered by immersing a cold body in hot water or lowering the temperature by pouring hot water onto the bamboo bamboo 13 with many branches and pouring it onto the bamboo bamboo 13. Since the temperature of the reservoir temperature 15 falls to a temperature that can be entered by a person of about 42 ° C., a method of guiding this to the hot spring section 7 through the pipe 16 is adopted.

図３は本発明の第１実施例を示す図である。図において、４は源泉であり、８０〜１００℃の温度である。１８は源泉からの熱水を蒸気発生器１９へ導く配管である。蒸気発生器１９のヒーター管２０により釜２１の中の水２２が蒸気２３となり高圧となって、パイプ２４によりタービン２５に送られ、タービン２５を回転させる。
タービン２５のシャフト２６により結合された発電機２７を回転させ、電力２８を発生する。２９は復水器で、水は窯２１に戻る。 FIG. 3 is a diagram showing a first embodiment of the present invention. In the figure, reference numeral 4 denotes a source, which is a temperature of 80 to 100 ° C. A pipe 18 guides hot water from the source to the steam generator 19. Water 22 in the pot 21 becomes steam 23 by the heater tube 20 of the steam generator 19 and becomes high pressure, and is sent to the turbine 25 by the pipe 24 to rotate the turbine 25.
A generator 27 coupled by the shaft 26 of the turbine 25 is rotated to generate electric power 28. 29 is a condenser, and the water returns to the kiln 21.

源泉４の温度はヒータ２０で温度が下がり、パイプ１６で温泉７に供給される。
本発明第２の実施例として源泉温度が８２℃等と低い場合は水２２の代わりにフレオン等沸点の低いものを用いる。気化したフレオンガス２３は配管２４を介してタービン２５に送られ回転する。このタービン２５の回転力は回転軸２６を介して発電機２７に与えられ、発電機のロータ（図示せず）を回転させ、発電機のロータが回転すると、発電機２７で交流電圧を発生させる。該発電機２７は交流電源２８として所定の負荷に送り、負荷を駆動することになるのは、第１実施例で述べたと同様である。 The temperature of the source spring 4 is lowered by the heater 20 and supplied to the hot spring 7 by the pipe 16.
As the second embodiment of the present invention, when the source temperature is as low as 82 ° C., a water having a low boiling point such as Freon is used instead of water 22. The vaporized freon gas 23 is sent to the turbine 25 via the pipe 24 and rotated. The rotational force of the turbine 25 is applied to the generator 27 via the rotating shaft 26, and the generator rotor (not shown) is rotated. When the generator rotor rotates, the generator 27 generates an AC voltage. . The generator 27 is sent to a predetermined load as the AC power supply 28 to drive the load, as described in the first embodiment.

このような一連の動作の中で、タービン２５からの蒸気は復水器２９に入り、配管３０を介してガス発生部２１に液体状２２で戻され循環して使用される。配管１８から出射された熱水はガス発生部２１を加熱するので温度が下がり４２℃程度となり、人が浸かれる温度まで下がるので、温泉７として利用することができる。     In such a series of operations, the steam from the turbine 25 enters the condenser 29 and is returned to the gas generation unit 21 through the pipe 30 in the liquid state 22 and circulated for use. Since the hot water emitted from the pipe 18 heats the gas generation unit 21, the temperature is lowered to about 42 ° C. and is lowered to a temperature at which a person is immersed, so that it can be used as the hot spring 7.

図４は本発明第３の実施例である。源泉４からの熱湯をヒーター管３２（形状は加熱効率を最大にするように曲管としてもよい）に導き、熱電素子３３を加熱する。熱電素子３３は熱を加えると、発電することは公知である。これを所定の電圧、電流を得るように直列又は並列に結合３４して電力２８を得る。第１と第２実施例は、タービンを使用する動的且つ大型，中型発電であり、第３実施例は熱電素子を使用するソリッドステートの静的且つ無音の小型発電であり、それぞれに適している温泉に使用する実施例である。   FIG. 4 shows a third embodiment of the present invention. Hot water from the source 4 is guided to the heater tube 32 (the shape may be a curved tube so as to maximize the heating efficiency), and the thermoelectric element 33 is heated. It is known that the thermoelectric element 33 generates electricity when heat is applied. This is coupled 34 in series or in parallel to obtain a predetermined voltage and current to obtain electric power 28. The first and second embodiments are dynamic, large and medium power generation using a turbine, and the third embodiment is a solid state static and silent small power generation using a thermoelectric element. This is an example used for hot springs.

第４の実施例では、前記の電気エネルギ以外のエネルギ、例えば熱エネルギとして地上式暖房や各種エネルギ用熱源と上記の温泉として使用する本発明である。従来の温泉では、源泉を冷やすのに、熱を外に捨てていた。本発明では、熱エネルギを発電機用やその他のエネルギに用いるので、地熱活用により、温泉地の収益となるので、温泉業者が地熱発電に反対しないので国家の地熱エネルギを有効に活用できる。   In the fourth embodiment, the present invention is used as above-mentioned hot springs as ground heat or various energy heat sources as energy other than the electric energy, for example, heat energy. In traditional hot springs, heat was thrown away to cool the source. In the present invention, since thermal energy is used for generators and other energy, the profit of the hot spring area is obtained by using the geothermal heat, so the hot spring trader does not oppose the geothermal power generation, so that the national geothermal energy can be effectively used.

本発明は温泉業者の反対が起こらず、また地熱発電のため新たな井戸を掘らなくても温泉の源泉を用いて発電することができるので、ローコストの発電ができるのみならず全国に点在する温泉を利用して発電などエネルギ供給することができ、その温泉近辺の温泉宿や民家の電力エネルギをまかなうことができるので、我が国の熱源泉を産業に活用できる産業上の利用可能性大である。   Since the present invention does not oppose the hot spring operators and can generate power using hot spring sources without digging a new well for geothermal power generation, it can be generated not only at low cost but also scattered throughout the country. Since it can supply energy such as power generation using hot springs, it can cover the power energy of hot spring inns and private houses in the vicinity of the hot springs, so it has great industrial applicability that can utilize Japanese heat sources for industry. .
