| 摘要 |
The invention relates to an electrolysis installation for decomposing water into hydrogen and oxygen, comprising: an electrolysis stack (5); a water recirculation system supplying water to the stack, the recirculation system comprising a circuit (11, 13) and a recirculation pump (15), a first and a second separator (7, 9) for separating from the water the hydrogen and the oxygen respectively produced in the stack (5); a hydraulic supply means which supply the recirculation circuit (11, 13) with deionised water so as to compensate for the water consumed by the production of gaseous hydrogen and oxygen, and an extinguishing means for inertising the first and second separators (7, 9) when the installation is shut down, characterised by extinguishing means which comprise a first and a second relief valve (36, 23) provided on the first and second separators (7, 9) respectively, the valves being provided to relieve the pressure in the two separators simultaneously while keeping the water level inside the two separators substantially constant, and by extinguishing means which control the supply means so as to completely fill the two separators (7, 9) with water once the two separators have been relieved of pressure.
