Abstract

The invention discloses an electrolysis water treatment system and a hydrogen production system. The electrolysis water treatment system comprises a first water inlet end, first purification equipment, second purification equipment, an intermediate tank, a water outlet end and a control valve pipeline, the first water inlet end is respectively communicated with the first purification equipment and the second purification equipment through a control valve pipeline, the intermediate tank is respectively communicated with the first purification equipment and the second purification equipment, and the water outlet end is respectively communicated with the first purification equipment and the second purification equipment; when the control valve pipeline works in a first discharging mode, the first water inlet end, the first purification equipment, the intermediate tank, the second purification equipment and the water outlet end are controlled to be communicated in sequence; when working in a second discharging mode, the first water inlet end, the second purification equipment, the intermediate tank, the first purification equipment and the water outlet end are controlled to be communicated in sequence; according to the invention, the automation and integration degree of electrolysis water treatment and the maintainability of equipment are improved.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an electrolysis water treatment system and a hydrogen production system. Background technique [0002] With the implementation of carbon emission and carbon neutrality policies, green hydrogen has been officially included in the national energy strategic plan. At present, green hydrogen is mainly obtained by electrolysis of alkaline solution (ALK) or pure water. Among them, electrolysis of pure water to hydrogen (PEM) is the focus of future research and development due to its advantages of high current density, high hydrogen production purity, and high load flexibility. . Due to the high water quality requirements of electrolytic pure water hydrogen production (PEM), a certain conductivity is required to meet the normal operation of the electrolyzer. Therefore, water treatment is also an indispensable part of the electrolytic pure water process. [0003] In the prior a...
