Process Optimization On Power Coal Of Panyi Coal Preparation Plant

Ignored by many people generally, the subject of coal cleaning process optimization has a bright application prospects. Through the data handling of three preparation equipments(Heavy medium shallow groove sorting machine, medium cyclone and spiral separator), the paper worked out the cleaned coal yield and cleans ash of each equipment,draw the partition curve,modeled it and got the separation density and the Ep and I. In this case, the raw coal data was detailed. Then the actual washability curve was drawn by the actual raw coal detailing data obtained by the translation of partition curve. Finally, the interpolation relation between synthetic coal and separation density was modeled. Combined with math software Matlab, the human-computer interface with good operability was founded. Under the precondition with the ash of synthetic coal the same as the ash in actual production, the structure of craft was optimized according to the actual production. The optimization result showed that the clean coal yiled was increased1.11%and the mount of clean coal was increased666thousand ton. Giving the the production decision and theoretical guidance, the creation of Matlab GUI was not only can adjust parameter to meet the demand when the quality requirements were changed but also maximize the economic benefit. Ultimately, for the deep research by othters, the problem unsolved and the prospect was proposed.
