摘要:
针对现有高斯模型进行液氨泄漏扩散模拟时未考虑气体空间叠加效应的问题,提出了改进的引入了时间叠加因素的高斯扩散模型。以某 工业园区用氨单位为实例,模拟毒气泄漏扩散情形,分析液氨泄漏后的浓度分布,在此基础上划分事故影响范围,结合周边实际情况,建立了 风险矩阵和人口密度矩阵,进行区域社会风险分析,验证了模拟的准确性,根据高斯扩散浓度范围及区域社会风险分析结果,确定了疏散区域 及最佳疏散路径,可为工业园区的应急疏散提供决策支撑。
Abstract:
An improved Gaussian diffusion model introducing temporal superposition factor was established in order to solve the problem that the traditional Gaussian model has not taken into account the spatial superposition effect of gas when conducting the simulation of liquid ammonia leakage and diffusion. Taking a enterprise which used the liquid ammonia in a certain industrial park as example, the situation of toxic gas leakage and diffusion was simulated. The concentration distribution after the liquid ammonia leakage was analyzed, and on this basis, the influence range of accident was divided. Combined with the actual circumstance in surrounding area, the risk matrix and population density matrix were established, and the regional social risk was analyzed to verify the accuracy of simulation. Based on the concentration range of Gaussian diffusion and the analysis results of regional social risk, the evacuation region and the optimal evacuation route were determined. It can provide decision support for emergency evacuation of industrial park.
