FEASIBILITY ANALYSIS AND DESIGN ON WINDBREAK NET FOR COAL YARD

摘要

Based on the investigations of the coal dust pollution status of the coal yard in Qin Huangdao port and referred to many dustproof techniques, this article indicates that compared with several dust-removing measures, windbreaks are effective barriers that help reduce or redirect wind to restrain the coal dust. Then the dustproof principle is analysed accordingly, and numerical simulation of air flow distributing after windbreak net is taken to obtain the main parameters of the net and the result suggests using windbreak net as main approach, combined with dry or wet method, as well as shelterbelt, and the best scheme of designing the windbreak net is put forward.
