The electrolytic bath, the direct current power supply, the water treatment supply device, the hydrogen treatment device and the oxygen treatment device are combined to form a set of system for producing hydrogen by electrolyzing pure water. Compared with an alkali liquor electrolysis hydrogen production system, the electrolysis raw material is pure water, alkali liquor does not need to be added into water to improve the conductivity, and pollution is avoided. Compared with the traditional coal hydrogen production and natural gas hydrogen production, the method has the advantage that carbon emission and other pollution can not be generated.
In the water treatment supply device of the hydrogen production system, a core component is a deionizer which is responsible for removing impurity ions in municipal water to form pure water with low conductivity meeting the requirements of a pure water electrolysis system. If the conductivity of the water supplied to the cell is too high, contamination of the cell, reduced life or failure of the cell may result. The deionizers have limited impurity ion treatment capacity and need to be replaced after working for a period of time, the replacement time is related to factors such as municipal water ion content, working environment temperature and the like, the prediction cannot be carried out in advance, and the system can automatically or inform an operator to manually shut down the system to replace the deionizers only when the system monitors that the water conductivity is close to or exceeds the standard. The process requires manual intervention in time and can cause system shutdown. If preventive replacement is used, the deionizer is wasted. For an unattended system for producing hydrogen by electrolyzing pure water in a field wind and light power plant, the downtime can be longer, and the hydrogen production is seriously influenced; therefore, the high-reliability water supply device of the system for producing hydrogen by electrolyzing pure water is provided.
