选煤厂封闭式煤炭输送通道实时安全监控系统

Real-time safety monitoring system for closed coal conveying way in coal preparation plant

为了保障选煤厂安全、高效生产,结合选煤厂封闭式煤炭输送通道的特点,提出了选煤厂封闭式煤炭输送通道实时安全监控系统,主要对系统中带式输送机、煤尘浓度、烟雾的监测方法和细水雾喷淋消除安全隐患技术进行了研究,并设计了系统架构,给出了不同情况下的应急处置方案。通过对整个生产环节的信息进行实时全面监测,使生产过程的安全系数大幅提高,可在保障选煤厂安全生产的同时,有效提高选煤员工的劳动生产率,提升选煤厂经济效益。

In order to ensure the safe and high-efficiency operation of coal preparation plants,a real-time safety monitoring system for closed belt conveyance way is proposed in line with the characteristics of such ways of coal preparation plants.The work made in the paper involves mainly the study of the methods for the monitoring of the operation of belt conveyor,detection and monitoring of concentration of coal dust and smoke and the atomising spray technique for elimination of safety hazards.Based on result of study the system architecture is designed and the schemes for dealing with emergency cases in different scenarios are worked out.As the information of the overall coal conveyance way is completely under real-time monitoring,the safety factor of the belt conveyance way is significantly improved.Practice shows that the use of the system can lead to not only higher safety in belt conveyance,but also effective rise of labor productivity and improvement of economic performance of coal preparation plant.
