摘要
散货物料风蚀不仅造成经济损失,还严重影响堆场周围环境空气质量。目前堆场常采用湿法、干法等抑尘方法,其中防风网抑尘法使用居多,其抑尘效果较好且具有一次投资长期受益的特点。然而防风网形状、开孔率、开孔孔径、防风网高度、堆垛距等影响防风网抑尘效果。本文从以上几个方面进行了分析,最终给出了较适宜的防风网设计参数。
Wind erosion of the bulk materials not only brings economic losses,but also affects air quality around the yard. At present,wet,dry and other dust suppression methods were used on the bulk yard. And porous fence are used most widely,its benefits include the high effect of dust suppression and the characteristic of an investment in long- term benefit. However,there are many factors have a great influence on the effect of the dust suppression, such as the shape of porous fence,porosity,the diameter of the holes,the height of porous fence,the distance between porous fence and stacking and so on.This paper analyzed the above aspects,and ultimately gave some appropriate design parameters of porous fence.
