低温液氢加注系统间歇泉现象风险评估研究

摘要

分析了液氢加注系统竖直管路内间歇泉现象产生的过程,总结了间歇泉现象产生的原因与危害性.采用改进的风险矩阵法,对间歇泉现象产生时给加注管路以及贮箱带来的危害进行了风险评估.为提前发现液氢加注过程中间歇泉现象引起的风险及风险发生后的风险转移提供理论参考,从而减小风险对液氢加注系统的影响.%The process of emerging geysering phenomenon in liquid hydrogen loading system vertical pipe was analyzed in detail,emerging reasons and harmfulness were summarized.At same time,the harmfulness of emerging geysering phenomenon to loading pipe and storage box was assessed by using the improved risk matrix method.A theoretical reference for finding out the risk of emerging geysering phenomenon in liquid hydrogen loading process in advance and transferring the risk after emerging were provided so that the influence on liquid hydrogen loading system could be minimized.
