浮选柱及精煤压滤机回收煤泥的实践研究郎会荣

郎会荣,李桂芬(七台河职业学院、黑龙江七台河　154600)　:分析了兴发选煤厂煤泥水处理系统的改造原因,并介绍了改造后的工艺流程主要特点,指出在原料煤性质、入料浓度相同的情况下,采用以浮选柱与加压过滤机作为浮选精煤压滤机联合使用,可提高选煤厂煤泥水处理能力和精煤产率。:浮选柱;压滤机;处理能力;精煤产率:TD943;TD462.2　　　　:B:1007-7677(2008)02-0067-01ThepracticeandresearchonrecoveringslimebyflotationcolumnandcleancoalpressurefilterLANGHui-rong,LIGui-fen(QitaiheProfessionalCollege,Qitaihe154600,China)Abstract:Thecauseoftransformationofslime-watertreatmentsystemintheXingfaCoalPreparationPlantisanalyzed.Themaincharacteristicsofnewtechnologicalprocessareintroduced.Itispointedthatusingflotationcolumnandpressurefilterasflotationcleancoalpressurefiltercanimproveslime-waterprocessingcapacityandcleancoalyieldinthecaseofkeepingaconsistencyintherawmaterialcoalpropertyandfeedcoalconcentration.Keywords:flotationcolumn;pressurefilter;processingcapacity;cleancoalyield1　,0.5mm,。。,,。,,,。2　(1),,200m3/h320m3/h,。(2),,。,。(3),,,,,。(4),,。3　(1)0.5mm15%21%,,。(2)3000mm,300m3/h,200m3/h。,,。4　、,2.0%,45t/a60t/a。4t/,800t,605/t,110/t,33.14。140,,。(69)672200833.2　(1)XJM-S16“,”,,,,,。(2),XK。,,,,。、。1.6kg/t。(3)。,,,,、,,。(4)。,。,“”。(5)。,,,120～150t。4　4.1　(1),100t/a。(2)549/t(,)。(3)110/t()。(4),2.0,2.0。(5)710。370,160,180。4.2　(1)1098,:100t×2.0%×549=1098(2)17%,35。100t×17%×(2.0-1.6)kg/t×5200/t=35(3)171。,740kW,115,21,21,35。(4)220。:100t×2.0%×110=220(5)742。:1098+35-171-220=742(),,。5　　　,,,200711。,。　　:邵良增(1964-),,,,。　(收稿日期:2007-11-01)(67)60t/a、,、。5　　　:,。,,,,。　　:郎会荣(1966-),,,,,。　(收稿日期:2007-12-13)69220083
