煤焦油加工厂冷却器泄露事故树分析

Fault Tree Analysis of Cooler Leakage in a Coal Tar Processing Factory

对煤焦油加工厂冷却器泄露事故进行了事故树编制.通过对事故树利用数值法进行分析,获取了该事故树的最小割集和最小径集.根据分析结果,提出了防止泄露事故发生的对策,并对每一种对策进行了简要阐释.最终形成了防止泄露事故的具体方案,取得了良好的效果.

A fault tree on cooler leakage of a coal tar processing factory is complied in this paper. Through analyzing this fault tree with value method,the minimum cut sets and minimum path sets are obtained. According to the result,this paper proposes some countermeasures to avoid the occurrence of cooler leakage. Meanwhile,it also gives some brief explanations to the countermeasures. Finally,this paper works out a specific program for preventing the leakage from happening,which has been proved to be effective.
