Description
【発明の詳細な説明】 本発明は耐振動性水電解装置に関するものである。[Detailed description of the invention] The present invention relates to a vibration-resistant water electrolysis device.
本電解装置の電解槽内には、電解槽内部で水素ガスと酸
素ガスとの混合が起るのを防止するために、陽極室と陰
極室との間にテフロン薄膜あるいはアスベスト薄膜等よ
りなる隔膜が設けられている。In the electrolytic cell of this electrolyzer, there is a diaphragm made of Teflon thin film or asbestos thin film between the anode chamber and the cathode chamber in order to prevent hydrogen gas and oxygen gas from mixing inside the electrolytic cell. is provided.
この隔膜は極めて破壊されやすいものであって、振動等
により陽極室と陰極室との間に圧力差が生じると容易に
破壊し、その場合、電解運転が不可能となる。This diaphragm is extremely easy to break, and if a pressure difference is created between the anode chamber and the cathode chamber due to vibration or the like, it will easily break, and in that case, electrolytic operation becomes impossible.
一方、従来の電解装置では、水素ガス導出側と酸素ガス
導出側との間の圧力バランスを保つために電解槽の陽極
室および陰極室に各各に接続した各気液分離装置間を相
互に連通させており、そのために外部振動に対しては連
通部をとおして電解液が移動することにより各気液分離
装置の液面が非常に変動し易い状態にある。On the other hand, in conventional electrolyzers, in order to maintain the pressure balance between the hydrogen gas outlet side and the oxygen gas outlet side, the gas-liquid separators connected to the anode and cathode chambers of the electrolyzer are mutually connected. Because of this, the liquid level of each gas-liquid separation device is extremely susceptible to fluctuations due to the movement of the electrolyte through the communication portion in response to external vibrations.
各気液分離装置の液面が変動すると気液分離装置の気相
部の圧力変動が生じ、そのとき電解槽の陽極室と陰極室
との間に差圧が生じるため、前記隔膜が破壊され、以後
の運転が不可能となる。When the liquid level in each gas-liquid separator changes, the pressure in the gas phase of the gas-liquid separator changes, and at that time, a pressure difference is created between the anode chamber and the cathode chamber of the electrolytic cell, causing the diaphragm to break down. , further operation becomes impossible.
ところで近い将来、太陽熱発電、波力発電、温度差発電
等が実施されようとしているが、これらの発電設備が洋
上に設置される場合には、その発電エネルギーを陸上ま
で運搬するのに、それを水電解によって水素エネルギー
に転換して行なうことが考えられる。By the way, solar thermal power generation, wave power generation, temperature difference power generation, etc. are about to be implemented in the near future, but when these power generation facilities are installed offshore, it will be necessary to transport the generated energy to land. It is conceivable that this could be done by converting it into hydrogen energy through water electrolysis.
このような場合、叙上のような従来の水電解装置のよう

The pressure balance in the compartment can be maintained by separately controlling the liquid level within the gas-liquid separator and the pressure of their gas phase and suppressing their respective fluctuations.
したがって洋上に設置した場合であっても、波等による
