摘要
随着中国经济的发展及人们环保意识的增强,露天煤场带来的粉尘问题也越来越引起重视。防风网作为一种控制煤堆场起尘与扩散的有效手段,近年来得到广泛应用。该文概要地介绍了国内外防风网的研究及应用现状;阐述了防风网的抑尘机理;分析总结了防风网的板型、开孔率和设置方式、网高、网宽、网-堆距等因素对其防风抑尘效果的影响,为今后在工程应用中合理选择防风网的各项参数提供了参考;并对防风网防尘技术在中国的发展提出建议。
With the development of economy and the enhancement of people＇s environmental protection consciousness, the open - air coal dust attracts increasing attentions from the public. Porous fences, acted as a kind of artificial windbreak, provide shelter for downwind stockpile by reducing the wind speed and have been widely used to abate dust emission. The dust - removing mechanism and the present research progress and engineering application of porous fence were introduced briefly in this paper to provide a reference for selecting the reasonable parameters of the windproof net in engineering application. The effect of windbreak＇s plate type, the porosity, the layout pattern, height and width on dust control efficacy were analyzed and summarized. Furthermore, several suggestions on the application of windbreak in China were offered.
