随着公众对石油需求量的增加,国内外的油罐油气泄漏及火灾爆炸事故也更频繁的出现。而石化企业火灾爆炸事故的主要原因之一是泄漏。本文主要针对有毒气体泄漏后的扩散过程,采用高斯模型建立模型,并应用VB软件进行数值模拟,体现有毒气体浓度和下风向距离的关系,评价可能造成的伤亡人数,为确定风险影响范围、减少伤亡提供依据。
As public demand for oil increased, oil and gas leaks at home and abroad and fire and explosion accidents also occurred more frequently. One of the main causes of fire and explosion accidents in petrochemical enterprises is leakage. In this paper, aiming at the diffusion process of toxic gas after the spill, Gaussian model is used to establish the model, and the numerical simulation is carried out by VB software. The relationship between toxic gas concentration and downwind distance is evaluated. The possible casualties are estimated. Provide basis for casualties.
