保德选煤厂炼焦配煤增效改造可行性研究

为实现煤炭资源合理优化配置,针对保德选煤厂工艺简单,产品单一的问题,研究了保德选煤厂精煤指标及原煤可选性,分析工艺改造可行性,并对改造后效果进行分析。结果表明,保德矿8-1原煤属于变质程度较高的气煤,通过分选精煤可达到炼焦配煤的指标要求,最大限度提升煤炭产品附加值,达到资源合理配置。选择方案1进行改造,对比现有方式效益能提高17 500万元/a;对主厂房改造量小,对系统影响小,改造后容易恢复现状,分选系统灵活,可随时调整生产方式。 In order to realize rational and optimal allocation of coal resources,aiming at the problems of simple process and single product in Baode coal preparation plant,the indexes of clean coal and the washability of raw coal were studied,and feasibility and effect of technological transformation were analysed.The results show that 8-1 raw coal belongs to gas coal with high metamorphic degree.Clean coal can meet the target requirements of coking coal blending,maximize the added value of coal products,and achieve the rational allocation of resources through coal separation. Selection of scheme 1 can improve by 175 million yuan per year efficiency. Compared with the existing mode,it has little influence on the system,and can easily restore the status quo after the transformation.The sorting system is flexible,and the production mode can be adjusted at any time
