摘要
重介质选煤工艺是煤炭分选中一种常用的选煤方式,悬浮液中重介质密度的变化直接影响对煤炭的分选效率和精煤产品的品质。分析了一种不依赖于控制模型的MFAC理论,对选煤过程中的重介质密度进行有效控制。仿真分析结果表明该控制方案具有算法响应速度快、可靠性好的优点,极大地提升了选煤企业的煤炭分选效率和精煤品质,具有极大的应用推广价值。
Dense medium coal preparation process is a common coal preparation method in coal separation.The change of dense medium density in suspension directly affects the separation efficiency of coal and the quality of clean coal products.This paper analyzed an MFAC control theory independent of the control model to effectively control the density of dense media in the coal preparation process.The results of simulated analysis show that the control scheme has the advantages of fast algorithm response and good reliability,which greatly improves the coal separation efficiency and the quality of clean coal in coal preparation enter-prises,and has great application and popularization value.
