Description

明細書  Specification
動力産出装置 技術分野 Power production equipment Technical field
本発明は発電所やエンジン等の動力産出装置における熱サイクルに関する。 背景技術  The present invention relates to a heat cycle in a power production device such as a power plant or an engine. Background art
発電所等で用いられるクローズサイクルでは熱源と冷却源を必要とする熱サ イタルが用いられる (文献：西脇仁一編、熱機関、東京大学出版会、 1965年 1 月 P70)。  In the closed cycle used in power plants and the like, a heat site that requires a heat source and a cooling source is used (Literature: Jinichi Nishiwaki, Heat Engine, University of Tokyo Press, January 1965, p. 70).
熱源の温度は冷却源の温度より十分に高くする必要があり、その高温を得る ため燃料が必要になる。しかし、燃焼ガスによる環境汚染の問題や将来的な燃 料不足の問題がある。 発明の開示  The temperature of the heat source must be sufficiently higher than the temperature of the cooling source, and fuel is required to achieve that high temperature. However, there is a problem of environmental pollution by combustion gas and a problem of fuel shortage in the future. Disclosure of the invention
本発明は上述の課題を解決するためになされたものであって、冷却源を持た ず、単に熱源のみを持つクルーズサイクルによる動力産出装置を考案した。 本発明は冷却源を持たないから、熱源の温度の制限が無くなり、太陽熱によ り自然に供給される大気温度の熱源から動力が得られ、燃料は不要になる。 図の簡単な説明  The present invention has been made in order to solve the above-mentioned problems, and has devised a cruise cycle power production device having no heat source and only a heat source. Since the present invention does not have a cooling source, there is no limit on the temperature of the heat source, power can be obtained from a heat source at ambient temperature that is naturally supplied by solar heat, and no fuel is required. Brief description of figures
図一 1は、本発明の代表的な実施例に関する動力算出装置の系統図をしめ す。同図中の構成要素は次ぎの通りである。 1 :熱源（太陽熱）、 2 :タービン、 3 :気液分離器、 4 :ポンプ、 5 :圧縮機、 6 :気液混合器、 7 :発電機、 8 :回転軸 発明を実施するための最良の形態  FIG. 11 is a system diagram of a power calculation device according to a representative embodiment of the present invention. The components in the figure are as follows. 1: Heat source (solar heat), 2: Turbine, 3: Gas-liquid separator, 4: Pump, 5: Compressor, 6: Gas-liquid mixer, 7: Generator, 8: Rotary shaft Best practice for carrying out the invention Form
本発明をより詳細に説明するために、図一 1にその系統図を示し説明する。 太陽からの熱により温度を保つ熱源 1を通過した作動流体はタービン 2に入り、 熱エネルギーが動力に変換され、タービン軸を回転させる。 タービン軸には発電機 7と圧縮機 5が回転軸 8で連結されている。タービン動 力は圧縮機を駆動し、また発電機出力を生じる。 In order to explain the present invention in more detail, FIG. 11 shows and illustrates a system diagram thereof. The working fluid that has passed through the heat source 1 that maintains the temperature by the heat from the sun enters the turbine 2, where the heat energy is converted into power and rotates the turbine shaft. A generator 7 and a compressor 5 are connected to a turbine shaft by a rotating shaft 8. Turbine power drives the compressor and produces generator output.
作動流体はタービン出口で約 10%〜40%が凝縮し、気液分離器 3で気相と 液相に分離される。  About 10% to 40% of the working fluid is condensed at the turbine outlet, and is separated into a gas phase and a liquid phase by the gas-liquid separator 3.
液相はポンプ 4により加圧され、気相は圧縮機 5により加圧される。液相と気 相は気液混合器 6で混合されて熱源 1に戻る。このようにして作動流体のクロー ズサイクルが形成される。  The liquid phase is pressurized by a pump 4 and the gas phase is pressurized by a compressor 5. The liquid phase and the gas phase are mixed by the gas-liquid mixer 6 and return to the heat source 1. In this way, a closed cycle of the working fluid is formed.
具体的な試算例を以下に示す。  A specific example of a trial calculation is shown below.
作動流体 ： 一酸化窒素 (NO)  Working fluid: Nitric oxide (NO)
タービン入口 ： 圧力 38(bar)、温度 170(k)  Turbine inlet: pressure 38 (bar), temperature 170 (k)
液相重量率 0%  Liquid phase weight ratio 0%
タービン出口 ： 圧力 0. 5(bar)、温度 108(k)  Turbine outlet: pressure 0.5 (bar), temperature 108 (k)
液相重量率 25%  Liquid phase weight ratio 25%
発電機出力 ： タービン軸動力の約 7%  Generator output: About 7% of turbine shaft power
上の計算結果では、作動流体はタービン出口で約 25%凝縮し、気相は流 れ全体の 75 %に減少するから圧縮機の消費動力がタービン軸動力より小さく なるため発電機出力が産出される。 産業上の利用可能性  According to the above calculation result, the working fluid is condensed at the turbine outlet by about 25%, and the gas phase is reduced to 75% of the total flow, so the power consumption of the compressor is smaller than the turbine shaft power, and the generator output is produced. You. Industrial applicability
作動流体として、気液飽和温度が大気温度より低いガス種を用いることにより、 大気温度を熱源として動力を産出することが可能となる。  By using a gas species whose gas-liquid saturation temperature is lower than the atmospheric temperature as the working fluid, it becomes possible to generate power using the atmospheric temperature as a heat source.
太陽熱により自然に供給される大気温度の熱源を用いて動力が得られるから 燃料は不要となる。  No power is required because power is obtained using an ambient temperature heat source that is naturally supplied by solar heat.
太陽熱を動力に変換する以外には自然への影響は生じず環境を汚染しな いクリーンエネルギーが得られる。  Other than converting solar heat into power, there is no effect on nature and clean energy that does not pollute the environment can be obtained.
