【摘要】：目前,工业生产安全越来越得到人们关心与重视,对于化学化工行业中的燃爆事故的研究也越来越加深入。本文围绕危险化学品燃爆事故后果调查和应急救援体系的构建开展了资料调查和研究工作。首先,针对化学化工行业可能发生危险化学品泄漏的不同情况,探讨了可能发生泄漏的五种模式：液体经管道泄漏、储罐中的液体经小孔泄漏、液体经管道上小孔泄漏、气体或蒸气经小孔泄漏以及两相流泄漏模式。研究总结喷射火计算模型、池火灾的计算模型、沸腾液体扩展蒸气爆炸(BLEVE)计算模型等典型的火灾事故模型和压力容器物理爆炸的计算模型、蒸气云爆炸(UVCE)计算模型等爆炸事故模型。其次,阐述了燃爆事故调查的目的和原则、事故调查组的组建和事故调查工作的程序和重点。并以南京“7·28”地下丙烯管道泄漏爆燃事故为例,从事故发生原点、泄漏物的认定、泄漏扩散范围、点火源、燃爆破坏范围,事故发生原因等角度开展事故调查和分析。最后,在事故调查和原因分析的基础上,分析公安危化品管理部门在此次事故的抢险救援中的经验和教训,并提出南京市危险化学品燃爆事故的应急救援体系框架。
[Abstract]:At present, people pay more and more attention to the safety of industrial production. The research on explosion accidents in chemical and chemical industry is also more and more in-depth. This paper focuses on the investigation of the consequences of explosion accidents of dangerous chemicals and the construction of emergency rescue system. First of all, in view of the different situations of hazardous chemical leakage in chemical and chemical industry, five possible leakage modes are discussed: leakage of liquid through pipeline, leakage of liquid in storage tank through small hole, leakage of liquid through hole in pipeline, leakage of liquid through pore in pipeline, leakage of liquid through pore in pipeline, leakage of liquid through pore in pipeline, Gas or vapor leakage through small holes and leakage mode of two-phase flow. Research and summary of jet fire calculation model, pool fire calculation model, Some typical fire accident models such as boiling liquid extended vapor explosion model, physical explosion model of pressure vessel and explosion model of vapor cloud explosion are presented. Secondly, the purpose and principle of explosion accident investigation, the establishment of accident investigation team and the procedure and emphases of accident investigation work are expounded. Taking the leakage and deflagration accident of Nanjing's "7.28" underground propylene pipeline as an example, from the origin of the accident and the determination of leakage, The scope of leakage and diffusion, ignition source, explosion damage scope, accident cause and other aspects of accident investigation and analysis. Finally, on the basis of accident investigation and cause analysis, this paper analyzes the experiences and lessons of the dangerous chemicals management department in the rescue and rescue of the accident, and puts forward the framework of the emergency rescue system for the explosion accident of dangerous chemicals in Nanjing.
