本文在对秦皇岛港煤堆场煤尘污染现状深入调查的基础上,对比几种主要防尘措施的特点,认为可采用设置防风网为主,其他已有装置为辅的防尘措施,综合处理,全面防治。并分析了防风网的防尘机理,对采用防风网后煤场的气流分布和扬尘状况进行了数值模拟,提出了利用防风网技术进行煤堆场防尘的合理方案。
Based on the investigation of the status quo of coal dust pollution in coal yard of Qinhuangdao Port, this paper compares the characteristics of several main dust control measures, and considers that dust-proof measures with wind-proof nets and supplemented by other existing equipment can be adopted and comprehensive treatment , Comprehensive prevention and treatment. The dustproof mechanism of the windbreaking net was analyzed. The airflow distribution and dusting condition in the coal yard after the windbreaking net was simulated were numerically simulated. The reasonable scheme of using the windbreaking net technology to dustproof the coal yard was put forward.
