Abstract
Excessive hydrogen content in oxygen is easy to lead to safety risks during low-load operation of hydrogen production by renewable energy hydro-electrolysis,which is mainly attributed to lye intermi-xing after separation tank. In view of lye intermixing,the impact of gas partial pressure difference on both sides of the diaphragm and operating load on the in-dex of hydrogen in oxygen accounting for more than 50％,improved measures to reduce the safety risk of hydrogen in oxygen were proposed. In the commonly used alkaline water electrolysis hydrogen production process,the addition of lye degassing tank and the a-daptive capacity modification of the supplement pump can eliminate the influence of lye mixing on hydrogen in oxygen,and the hydrogen content in by-product oxygen can be achieved below 1％ even when running at a low load of 10％,which can meet the safety risk reduction and more fully adapt to the unstable energy characteristics of renewable energy power generation.关键词
