摘要:

神渭输煤管道项目设计能力1000万t/a,因关中地区环保政策限制及终端用户消纳能力不足(361万t/a)导致煤浆富余。针对该问题,提出了煤浆脱水后的储装运系统优化设计方案。通过融合物料特性分析(粒度小于等于1.2mm、含水率21%~28%、堆积密度0.75~0.92 t/ m3) 与一期工程实践经验,创新性地采用“顶堆侧取堆取料圆形储煤场+智能装车”系统架构,攻克了湿粘煤料储运技术瓶颈。经3年实际运行,系统累计输送脱水煤2000万t, 给企业创造了良好效益。研究成果可为大规模湿粘煤储运工程提供参考。

Abstract:

The Shen-wei pipeline coal transport project is subject to the environmental protection industrial policy of the Guanzhong region, and the large gap between the transportation capacity of pipeline coal transport (10 million tons/year) and the consumption capacity of the terminal chemical plant leads to a large surplus of coal slurry. In order to ensure the safe and stable operation of coal transport pipeline and the best comprehensive benefit of coal transport pipeline, surplus coal slurry needs to be dehydrated and sold. At present, there is no engineering case of this scale in China for reference. Combining the product characteristics of coal slurry after dehydration (fine, wet and sticky) and the design experience of Shen-wei pipeline coal transport project phase I, the scheme selection and optimization design of each process system of storage and loading are carried out. At present, the surplus coal slurry application engineering storage and loading system has been running stably for 3 years, and has transported about 20 million tons of coal in total, which has created good benefits for enterprises.
