Problems solved by technology

[0003] In recent years, photoelectric power generation is often used in hydrogen production technology. Based on the inherent characteristics of photovoltaic power generation such as intermittent and fluctuating, electrolyzers need to be started and stopped frequently. That is, affected by weather conditions, electrolyzers often need to be started when the light is good. , shut down when the light is poor and the photovoltaic power is insufficient, so when the electrolyzer is turned on again, it is necessary to heat the electrolyte in the electrolyzer to the working temperature before the electrolytic reaction can occur in the electrolyzer, which greatly affects the hydrogen production efficiency of the electrolyzer

Abstract

The invention discloses a hydrogen production method and a hydrogen production system.The hydrogen production method comprises a hydrogen production electrolyte circulating method, and the hydrogen production electrolyte circulating method comprises the following steps that a gas-liquid mixture discharged from an electrolytic bath is subjected to heat preservation treatment, and layered hot gas and hot electrolyte are obtained after the gas-liquid mixture stands; carrying out at least one time of gas-liquid separation on the hot gas to obtain to-be-purified gas containing no thermal electrolyte, recycling the separated thermal electrolyte, and carrying out heat preservation treatment again; carrying out purification treatment on the gas to be purified; and the thermal electrolyte subjected to heat preservation treatment is circularly conveyed to the electrolytic bath to be subjected to an electrolytic reaction. According to the technical scheme, the hydrogen production efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of hydrogen production, in particular to a hydrogen production method and a hydrogen production system. Background technique [0002] At present, in the hydrogen production process, the gas-liquid mixture on the hydrogen side and the gas-liquid mixture on the oxygen side produced by the electrolysis of the electrolyzer enter their respective gas-liquid separators, and the electrolytes separated by the gas-liquid separators are combined and then enter the heat exchanger for cooling. , and then returned to the electrolyzer. [0003] In recent years, photoelectric power generation is often used in hydrogen production technology. Based on the inherent characteristics of photovoltaic power generation such as intermittent and fluctuating, electrolyzers need to be started and stopped frequently. That is, affected by weather conditions, electrolyzers often need to be started when the light is good. , shut down when...
