摘要/Abstract

摘要： 为探究化工园区多储罐同时爆炸引起的事故风险,提出多储罐爆炸超压损伤演化过程研究方法。首先,计算单一储罐爆炸损伤概率和单一储罐爆炸损伤概率;然后,考虑多储罐同时爆炸,研究多储罐爆炸超压损伤演化过程;最后,以某化工园区为例,验证多储罐同时爆炸的区域损伤概率分布。结果表明:演化结果以储罐o₂的区域损伤概率分布为主,后继区域损伤概率分布逐渐减小。研究得到最大损伤概率储罐爆炸顺序集合、对应损伤概率集合和储罐损伤概率分布集合,可计算多储罐同时爆炸的区域损伤概率。初始爆炸时提供的能量差异与储罐爆炸超压损伤演化过程的不同,造成化工园区储罐爆炸过程的复杂性。

Abstract:

In order to study the accident risks caused by the simultaneous explosions of multiple storage tanks in chemical industrial parks, a research method for the overpressure damage evolution process of multiple tank explosions was proposed. First, the explosion damage probability of a single storage tank and the explosion damage probability distribution of a single storage tank were calculated. Then, considering the simultaneous explosions of multiple storage tanks, the overpressure damage evolution process of multiple tank explosions was studied. Finally, the regional damage probability distribution of the simultaneous explosions of multiple storage tanks was obtained. The results show that the evolution result is mainly based on the regional damage probability distribution of Tank o₂, and the subsequent regional damage probability distribution decreases gradually. Through the research, the tank explosion sequence set with the maximum damage probability, the corresponding damage probability set and the tank damage probability distribution set are obtained, and the calculation of the regional damage probability distribution of the simultaneous explosions of multiple storage tanks is realized. The complexity of the storage tank explosion process in chemical industrial parks is caused by the differences in the energy provided during the initial explosion and the differences in the overpressure damage evolution process of storage tank explosions.

Key words: multi-tank explosion, damage evolution, explosion overpressure, regional damage, probability distribution
