| 摘 要： | 针对因液化石油气泄漏而引发的火灾爆炸事故，结合液化石油气的主要物质的物理化学特征，明确了液化石油气泄漏后可能发生中毒、闪火、池火和BLEVE爆炸等4种事故。利用ALOHA模拟软件对4种事故进行模拟计算，得出了在不同风速和不同泄漏孔径情况下的事故危害影响范围，明确了泄漏扩散距离与风速和泄漏孔径大小之间的关系，提出了人防专业队工程在液化石油气罐泄漏情况下的影响范围，为液化石油气罐泄漏灾害发生时的有利救援提供了参考。 |

| Abstract: | There are combustion and explosion accidents caused by the leakage of the liquefied petroleum gas (LPG). Four kinds of accidents including poisoning, flash, pool fire and BLEVE explosion were clarified combined with the physical and chemical characteristics of the main constitute of LPG. ALOHA simulation software was applied for the simulation of the four kinds of accidents. It is concluded that the different wind speeds and different leak apertures have different influence on the accident area. The relationships between the dispersion distances of LPG leakage and wind speeds and the leakage apertures as well were obtained. Further, the area of the influence of civil air defense professional team engineering in case of the LPG leakage was put forward. The results provide reference for the disaster response when the LPG leaks. |
