摘要
针对液氨泄漏事故建立基于高斯烟羽模式的泄漏扩散模型,模拟液氨储罐泄漏事故,分析液氨扩散后的浓度分布,探讨其危害范围和应急救援区域划分,并其引发人员中毒和爆炸的危险性。研究结果表明:用高斯烟羽模型可以模拟液氨泄漏,模拟评估结果可为现场救援人员采取安全防护措施、疏散现场群众及制定危害管理计划等提供理论依据和技术指导。
A diffusion model of liquid ammonia leakage accident was built based on Gaussian plume mode. An accident of a certain tank containing liquid ammonia was taken as the example. Distribution of diffusion concentration,hazard distance and emergent rescue zones were simulated numerically. On basis of simulation,the hazards of intoxication and explosion were evaluated. Research results show that Gaussian plume model could simulate liquid ammonia leakage accident,and that simulation and evaluation results could provide theoretical basis and technical guidance for emergency rescuers to take safety protection measures,evacuate crowds nearby and make hazard management plans.
