重气体泄漏的扩散特征及应急处置要点

Diffusion Characteristics of Heavy Gas Leakage and Key Points of Emergency Disposal

文章对重气体扩散行为的特点做了简要介绍,对近年重气扩散的研究进展进行综述,结合浙江温岭“6·13”液化石油气罐车爆炸事故案例,以ALOHA软件模拟,结合现场目击照片分析的形式,对事故现场液化石油气的扩散过程进行还原,根据重气泄漏扩散的一般规律,总结了重气泄漏事故现场处置工作的若干通用原则。

The paper briefly introduces the characteristics of heavy gas diffusion behavior,summarizes the research progress of heavy gas diffusion in recent years,combines the case of“6·13”explosion accident of lique fied petroleum gas tanker in Wenling,Zhejiang,restores the diffusion process of liquef ied petroleum gas at the accident site in the form of ALOHA software simulation and on-site witness photo analysis,some general principles are summarized for field disposal of heavy gas leakage accidents according to the general law of heavy gas leakage and diffusion.
