空气层结对港口细煤粉污染扩散的影响分析
Influnce analysis of air stratification to proliferation of fine mine particle pollution in port
摘要
Abstract
In this paper, the diffusion of air stratification to proliferation of fine mine particle pollution in port was analyzed. The peak concentrations of pollutants under stable stratification,neutral stratification and unstable stratification were 1.3 mg/m3、0.27 mg/m3、0.02 mg/m3 when the distance from the source was 0.5 km.And the peak concentrations of pollutants were given when the wind velocity were 5.5 m/s and 7 m/s. The corresponding conclusions are as follows :the concentration distribution is relatively small peak when turbulence in an unstable stratification;with stratification became stable,the concentration is decreased along with the extension of downwind distance. The distance of the ground largest concentration will increase with the increase of stability.关键词
