淮北选煤厂乳化浮选系统实践周宗丰,朱宏政,赵晴(淮北矿业集团淮北选煤厂,安徽淮北235025)摘要:淮北选煤厂属于矿区型选煤厂,入选多个矿井原煤,煤种复杂、煤泥含量大以及煤质不稳定,为选煤厂的浮选工艺控制带来困难,增加了选煤厂的运行成本。为提高精煤产率,减少浮选药剂使用量,淮北选煤厂安装应用一套乳化加药系统,通过现场试验的结果显示:捕收剂乳化后进入浮选,总精煤灰分平均约降低2.5%,精煤产率也有明显提高,浮选可燃体回收率平均增加约3%。使用该系统为企业节省了药剂耗量,提高了经济效益,在行业上起到了示范作用,产生一定的社会效益。关键词:选煤厂;药剂乳化;浮选;搅拌器中图分类号:TD943文献标识码:A文章编号:1005⁃8397(2023)04⁃0016⁃04PracticalresearchonemulsificationflotationsysteminHuaibeiCoalPreparationPlantZHOUZong-feng,ZHUHong-zheng,ZHAOQing(HuaibeiMiningGroup,HuaibeiCoalPreparationPlant,Huaibei,Anhui235025,China)Abstract:HuaibeiCoalpreparationplantbelongstotheminingareatypecoalpreparationplant,selectedmanyminerawcoal,coalcomplex,largeslimecontentandunstablecoalquality,fortheflotationprocesscontrolofcoalpreparationplantbroughtdifficulties,increasedtheoperationcostofcoalpreparationplant.Inordertoimprovethecleanedcoalyieldandreducetheuseofflotationreagent,HuaibeiCoalPreparationPlanthasinstalledandappliedasetofemulsifieddosingsystem.Thefieldtestresultsshowthatthetotalcleanedcoalashconten...
