摘　　要：选取加氢站的储氢装置为例,定量研究储氢装置的物理爆炸、气云爆炸、射流火、火球等典型事故,利用燃烧爆炸和安全评价相关理论计算冲击波超压、热辐射等重要参数,研究事故后果。基于定量风险分析(QRA)方法,计算得到加氢站内外建筑物安全距离、个人风险,为预测氢基础设施的安全性提供科学依据,为保障安全用氢提供技术手段。The hydrogen storage device in a hydrogen refueling station is selected as an example to quantitatively study the four typical accidents of the hydrogen storage device,including physical explosion,gas cloud explosion,jet fire,and fireball.The important parameters such as shock wave overpressure,thermal radiation,and the consequences of the accident are calculated using theories related to combustion explosion and safety evaluation.Based on the quantitative risk analysis(QRA)method,the safety distance between buildings inside and outside the hydrogen refueling station and personal risks are calculated,providing a scientific basis for predicting the safety of hydrogen infrastructure and providing technical means for ensuring the safe use of hydrogen.
