液氨泄漏事故伤害范围模拟及人员疏散研究

Liquid Ammonia Leakage Accident Injury Range Simulation and Evacuation

基于高斯烟羽模型,应用风险评估软件对液氨储罐在不同泄漏模式下的液氨伤害范围进行模拟,得出各模式下液氨伤害范围的变化规律,并分析了风速对液氨扩散的影响作用。制定了液氨储罐特定泄漏模拟场景下的人员疏散路径,为液氨泄漏事故下的人员应急救援以及疏散等提供参考。

Based on Gaussian plume model ,the risk assessment software is applied to simulate liquid ammonia leakage damage ranges in different leakage modes of the liquid ammonia tank ,the variation of liquid ammonia injury scope for each mode is obtained and the effect of wind speed on liquid ammonia diffusion is also analyzed .The evacuation route in the spe-cific leakage simulation scenario of liquid ammonia tank is formulated ,which can provide reference for emergency rescue and evacuation under accident of the liquid ammonia leakage .
