医院火灾消防处理过程有机污染物扩散模型研究

Research on Model of Organic Pollutants Diffusion in Hospital Fire Fighting Process

针对严峻的环境污染现状与维护人民生命财产安全的现实需求,设计了医院火灾消防处理过程有机污染物扩散模型。首先以高斯分布为基础分析多起火点共同的作用,再根据烟雾扩散形式建立扩散模型;基于此,求解平面空间中确定点源的高斯分布模型参数,再利用烟雾浓度与影响因子间的关联性获取浓度分布函数,依据浓度梯度与扩散速度判定医院各区域有机污染物的浓度变化。仿真实验表明该模型可以精准预测有机污染物的扩散形式,具备较好的稳定性和可靠性。

In view of the severe environmental pollution and the need to maintain the safety of people's life and property,the diffusion model of organic pollutants in the process of hospital fire control was designed.Firstly,the common action of multiple ignition points is analyzed based on Gaussian distribution,and then the diffusion model is established according to smoke diffusion form.The parameters of the Gaussian distribution model for determining the point sources in the plane space were solved,and then the correlation between smoke concentration and influence factors was used to obtain the concentration distribution function.The concentration variation of organic pollutants in each area of the hospital was determined according to the concentration gradient and diffusion velocity.The simulation results show that the model can accurately predict the diffusion form of organic pollutants and has good stability and reliability.
