摘要
随着国家大气环境污染治理标准的不断提高,燃煤电厂露天条形储煤场的封闭化治理势在必行。与传统钢结构相比,封闭式储煤场采用空气支承式膜结构具有抑尘效果好、自重轻、地质条件适用性好、透光性好、耐腐蚀、耐候性强、自洁性能好,施工工期短且造价低等优点。通过工作原理分析,从膜结构的使用寿命、防火、防爆、安全性能以及工程造价等方面进行研究、论证,空气支承式膜结构能满足工程环保治理的要求。经工程实践验证,空气支承式膜结构储煤场满足技术要求,结果符合预期,具有工程推广价值。
With the continuous improvement of the the national air pollution control standards,enclosed management was necessary for outdoor strip-shape coal storage yard in coal-fired power plants.Compared with the traditional steel structure,the airsupported membrane structure used by the enclosed coal storage yard had the advantages of good dust suppression effect,light weight,good adaptability on geological conditions,good light-transmittance,corrosion resistance,good weather-resistance,good self-cleaning performance,short construction period and low cost.Through the analysis of operation principle,this paper studied and demonstrated the service life,fire prevention,explosion proof safety performance and engineering cost of membrane structure,and concluded that the air-supported membrane structure could meet the requirements of the environmental protection.It had been verified by engineering practice that the air-supported membrane structure in the coal storage yard could meet the technical requirements,and as expected,it had the promotion value in the engineering application.
