摘要
火灾消防时期会排放出很多污染物,主要呈烟雾气形态。鉴于污染现状和保护大众生命财产安全的现实需求,提出并构建基于高斯分布的火灾消防处理时期排放污染物的非稳态扩散模型。为了提高污染物非稳态模型构建精确度,详细分析并计算了浓度背景值、高斯模型参数、风速影响阈值、风向影响参数和湿度影响参数等扩散模型构建需要考虑的因素。基于因素确定,针对单一火灾消防处理点排放污染物非稳态扩散模型进行构建。以污染物分布情况为依据,在设定的污染物范围结构中,构建污染物非稳态扩散模型。
During the fire emergency period,many pollutants will be emitted,mainly in the form of smoke.In view of the current situation of pollution and the practical need to protect the safety of people s lives and property,an unsteady diffusion model of pollutants discharged during the fire treatment period based on Gaussian distribution is proposed and constructed.In order to improve the accuracy of the unsteady model construction of pollutants,the factors that need to be considered in the construction of diffusion models such as concentration background value,Gaussian model parameters,wind speed influence threshold,wind direction influence parameters and humidity influence parameters are analyzed and calculated in detail.Based on the factors,a non-steady-state diffusion model of pollutant emissions from a single fire-fighting treatment point was constructed.
