摘　　要：河西地区是我国重要产煤区和新疆煤炭进入内地的重要中转站。河西地区的煤炭物流基地数量繁多,且规模大小不一,封闭式煤场与露天煤场并存,装卸方式也大不相同。河西地区特殊的地理条件和煤炭硫磷含量较高,挥发性较强等的特征,使得煤粉扬尘问题严重,对环境和周边居民身体和生活造成了极大的影响,同时造成煤炭资源浪费。本文提出建设河西地区煤炭物流基地扬尘污染防控综合治理体系,包括:设置挡风抑尘网墙,采用复合型抑尘剂和速溶型抑尘剂,对运煤汽车采用自动化抑尘喷洒装置和装卸过程采用高压细小水雾喷洒装置,以实现对煤粉扬尘的控制。本研究亦可为其他具有相似气象及地形的煤炭物流园区提供扬尘治理方案参考。Hexi region is the main coal-producing area in China and an important transit station for Xinjiang coal to enter the mainland.The coal logistics parks in Hexi region are dotted with a large number of different sizes,closed coal yards and open-pit coal yards coexist,and the loading and unloading methods are also very different.Due to the special geographical conditions and the characteristics of high sulfur and phosphorus content and strong volatility of coal in Hexi area,the problem of pulverized coal dust is serious,which has a great impact on the environment and the health and life of surrounding residents,and results in a waste of coal resources.In view of this situation,this paper puts forward the comprehensive control system of dust pollution in Hexi Coal Logistics Park,including:setting up wind screen wall,adopting compound dust suppressant and instant dust suppressant,automatic dust suppression spraying device for the coal truck and high pressure fine water mist spraying device for loading and unloading process to realize the control of pulverized coal dust.It is also hoped to provide a reference for dust control schemes for other coal logistics parks with similar meteorology and topography.
