Description
技术领域Technical field
本实用新型涉及电解水制氢一体化集成设备技术领域，具体为一种AEM电解水制氢一体化集成设备。The utility model relates to the technical field of integrated equipment for electrolyzing water and producing hydrogen, specifically an AEM integrated equipment for electrolyzing water and producing hydrogen.
背景技术Background technique
氢能作为最理想的能源载体正成为人们关注的焦点，随着氢燃料电池汽车的推广，氢气市场需求递增，加氢站建设驶入快车道，未来与光伏发电或风力发电配套的电解水制绿氢将成为发展趋势，对于传统的碱液电解制氢氧电解槽存在着体积大、能耗高(～5kWh/Nm3H2)、效率低(50％～70％)、响应时间长(分钟-小时级)，大规模状态下多设备协调控制策略复杂、体积大，现有的PEM电解设备虽然相较于碱液电解槽具有一定优势，但也受制于膜电极技术的发展，存在成本高、维护时催化剂和膜无法单独替换等问题，还有一种固体氧化物电解池尚处于研究阶段，其也受到工作温度高(800～1000℃)装置复杂等限制，因此，需研究一种新型低成本，低能耗，模块化，响应速度快的一体化电解设备，来克服这些问题，实现和风光发电结合的电解水绿氢制备。Hydrogen energy, as the most ideal energy carrier, is becoming the focus of people's attention. With the promotion of hydrogen fuel cell vehicles, the demand for hydrogen is increasing, and the construction of hydrogen refueling stations is entering the fast lane. In the future, electrolytic water production will be matched with photovoltaic power generation or wind power generation. Green hydrogen will become a development trend. For the traditional hydrogen and oxygen electrolyzers produced by alkali electrolysis, there are problems such as large size, high energy consumption (~5kWh/Nm 3 H 2 ), low efficiency (50% ~ 70%), and long response time ( minutes to hours), multi-equipment coordinated control strategies are complex and large in large-scale conditions. Although existing PEM electrolysis equipment has certain advantages over alkali electrolyzers, it is also subject to the development of membrane electrode technology and has costs. High, the catalyst and membrane cannot be replaced separately during maintenance. There is also a solid oxide electrolytic cell that is still in the research stage. It is also limited by the high operating temperature (800~1000℃) and the complexity of the device. Therefore, a new type of solid oxide electrolytic cell needs to be studied. Integrated electrolysis equipment with low cost, low energy consumption, modularity and fast response speed can overcome these problems and achieve the production of green hydrogen from electrolyzed water combined with wind and solar power generation.
目前，大规模商用的碱性电解水制氢设备体积较大，响应速度慢(例如不能直接利用风光发电)，并且对环境的影响较大(例如电解液浓度过高，如30wt％浓度的KOH)，而新型的PEM电解水制氢设备受限于膜电极技术的发展，采用贵金属和钛等材料，造价高，同时催化剂和交换膜无法直接更换，后期维护保养不便，基于阴离子交换膜AEM(Anion-ExchangeMembrane)电解水制氢设备造价低，效率高，响应速度快，体积小，但目前没有可匹配的相关配套设施。At present, large-scale commercial alkaline water electrolysis hydrogen production equipment is large in size, has slow response speed (for example, it cannot directly use wind and solar power generation), and has a large impact on the environment (for example, the electrolyte concentration is too high, such as 30wt% KOH concentration ), and the new PEM water electrolysis hydrogen production equipment is limited by the development of membrane electrode technology. It uses materials such as precious metals and titanium, which is expensive. At the same time, the catalyst and exchange membrane cannot be directly replaced, and subsequent maintenance is inconvenient. Based on the anion exchange membrane AEM ( Anion-Exchange Membrane) electrolytic water hydrogen production equipment has low cost, high efficiency, fast response speed and small size, but there are currently no matching related supporting facilities.

At the same time, the main mechanical components can be made of stainless steel, carbon steel or other low-cost alloy materials, and the electrolyte is made of low-concentration alkaline solution (≤10wt% ), has low corrosiveness, is more environmentally friendly, and costs less than PEM electrolyzers. It can be directly connected to wind and solar power generation systems without the need for intermediate energy storage conversion processes. It has lower electricity costs, fast response speed, low energy consumption, small size, and is more Environmentally friendly, the electrolyte entrained with oxygen and hydrogen from the hydrogen production module 3 flows into the oxygen-side gas-liquid separation module 4 and the hydrogen-side gas-liquid separation module 5 respectively. Under the action of gravity, the gas and liquid are separated and cooled. After the system is cooled, the electrolyte enters the filter from the connecting pipes at the bottom of the oxygen-side gas-liquid separation module 4 and the hydrogen-side gas-liquid separation module 5, and finally flows back into the hydrogen production module 3 through the circulation pump, while oxygen and hydrogen enter the oxygen purity module respectively. Detection module 6 and hydrogen purification module 7. After passing the test, the oxygen coming out of the oxygen side gas-liquid separation module 4 can enter the oxygen storage device or be directly vented through the vent according to demand. The hydrogen coming out of the hydrogen side gas-liquid separation module 5 can enter The hydrogen purification module 7 is washed and purified, and then enters the hydrogen purity detection module 8. After passing the test, it is output to the energy storage unit 9 for storage. If the purity is found to be unqualified after testing, it will automatically flow back to the hydrogen purification module 7 through the built-in solenoid valve. Perform secondary purification to ensure the purity and safety of the output hydrogen and improve equipment reliability.
