Abstract

The invention discloses a water electrolysis hydrogen production system with a vacuum function, which comprises a water electrolysis mechanism, an oxygen separation tank, an oxygen washing tank, a hydrogen separation tank and a hydrogen washing tank, a gas inlet of the oxygen separation tank and a gas inlet of the hydrogen separation tank are respectively connected with an oxygen lead-out port and a hydrogen lead-out port of the water electrolysis mechanism; a gas outlet of the oxygen separation tank is connected with a gas inlet of the oxygen washing tank, a gas outlet of the hydrogen separation tank is connected with a gas inlet of the hydrogen washing tank, and a gas outlet of the hydrogen washing tank is sequentially connected with a hydrogen drying device and a hydrogen purifying device. And the vacuum system is connected with the hydrogen separation tank, the hydrogen washing tank, the hydrogen drying device and the hydrogen purification device and is used for exhausting air therein. According to the water electrolysis hydrogen production system with the vacuum function, the vacuum system is additionally arranged, air in the hydrogen production system is exhausted, and waste of hydrogen is avoided.

Description

technical field [0001] The invention is applicable to the technical field of hydrogen energy, and in particular relates to an electrolysis water hydrogen production system with vacuum function. Background technique [0002] With the advent of the era of photovoltaic and wind grid parity, new energy will continue to maintain a rapid growth trend. Due to the natural volatility and intermittency of new energy power generation, a high proportion of new energy power systems face unprecedented challenges in terms of safety and stability, and must have enough flexible adjustment resources. [0003] As a secondary energy source with a wide range of sources, clean and carbon-free, flexible and efficient, and rich in application scenarios, hydrogen energy is regarded as one of the important solutions to achieve carbon neutrality, and is gradually becoming an important direction of the global energy technology revolution and industrial development. , my country has also incorporated hy...
