提高选煤生产效率的系统优化与改造

System optimization and reformation to improve the efficiency of coal preparation plant

阐述了纳林河选煤厂生产过程中存在设备保护误报警、煤流堵塞造成生产延误、重介悬浮液密度不稳定导致产品质量波动等影响生产效率的问题。通过对生产系统进行分析,采取合理的技术改造后,系统的稳定性、选煤效率、产品质量均有提高,设备故障率大大降低,减少了维修成本,达到了提质增效的效果。

In view of the frequent occurrence of electrical failures during the production process, the actual production efficiency fails to meet the design expectations, the extremely unstable belt protection and chute blockage alarm system, and the unstable density control system of heavy medium suspension, which cause large fluctuations in the coal quality of the cleaned coal products, Nalinhe Coal Preparation Plant specially proposes the subject of improving the production efficiency of coal preparation for research, The existing problems that restrict the continuity of production and the stability of product quality are systematically analyzed and optimized.After the transformation, the stability of the system, the efficiency of coal preparation, and the product quality have been improved, and the equipment failure rate has been greatly reduced.It not only saves power consumption for enterprises but also improves product recovery rate, which can reduce cost and increase efficiency by about 15 million yuan every year.
