HYDROGEN AND OXYGEN GENERATOR AND ITS OPERATION

摘要

PROBLEM TO BE SOLVED: To provide a hydrogen and oxygen generator capable of delivering high-pressure and high-purity gaseous hydrogen and oxygen without using a power source such as a high-pressure pump in which impurities are liable to mix while keeping the inside of a pure water vessel at a high pressure and to furnish its operation. SOLUTION: This hydrogen and oxygen generator consists of a hydrogen and oxygen generating device 1 provided with a water electrolytic cell 2 set in a pure water vessel 3, a makeup water tank 14 connected to the vessel through a makeup water line 13 to replenish pure water to the vessel 3 and a pure water feeder 21 connected through a pure water feed line 20 to supply pure water to the makeup water tank 14. A bypass 22 leading to the makeup water tank from a gaseous oxygen discharge line 5 and a pressure imparting line 26 are furnished, a degassing line 15 communicated with the makeup water tank is provided, and stop valves A to F are furnished to the respective lines.
