摘　　要：以某氯碱厂液氯泄漏为研究对象,采用计算流体力学(CFD)Fluent软件模拟计算得出区域一、区域二、区域三疏散路线中各监测点的氯气扩散实时浓度,并考虑全部泄漏场景的发生概率,通过不同泄漏场景中各位置的氯气实时浓度来评估不同的人员疏散方案,优选出在所有泄漏场景中人员累计中毒风险较小的最优疏散路线。优化结果表明:当某氯碱厂液氯发生泄漏事故时,区域一的第二条路线、区域二的第一条路线和区域三的第二条路线为最优疏散路线。Taking the liquid chlorine leakage of a chlor-alkali plant as the research object,this paper conducts numerical simulation to work out the real-time concentration of chlorine in the monitoring points on regional one,regional two and regional three evacuation routes by the Computational Fluid Dynamics(CFD)software Fluent.Then the paper takes the occurrence probability of all the leakage scenarios into account,evaluates different evacuation plans according to the real-time concentration at each position.Finally the paper selects the optimal evacuation routes with the minimal cumulative poisoning risk of personnel in all the leakage scenarios,i.e.,the second route of region one,the second route of region two and the second route of region three.
