摘要
泄漏、扩散、点火这3个因素,在液氨泄漏源附近一定的时空范围内,按不同时序可以演变成BLEVE、喷射火、闪火、蒸气云爆炸和大气中扩散等5种事故后果模式。该文针对液氨的独特理化性质,对液氨泄漏及其在大气中扩散物理过程进行了分析,并通过算例对比研究了5种液氨事故模式的危害范围和程度,为预防液氨泄漏事故发生和液氨泄漏事故预警提供参考。
Three factors, such as leakage, diffusion, and ignition, could evolve into five kinds of accident modes, BLEVE, jet fire, flash fire, vapor cloud explosion and poisonous vapor diffusion in air in close vicinity of leakage source of anhydrous ammonia. Owe to the particular characteristics of anhydrous ammonia, its particular physical mechanism of leakage and diffusion is analyzed. Damage range and extent of five kinds of accident modes are comparatively studied by an example.
