隔膜式压滤机在济三煤矿井下的应用高艳阳1,焦红光1,靳建伟2(河南理工大学材料科学与工程学院,河南焦作454003;2.登封市煤炭协会,河南登封452470)＊摘要:为处理水煤脱水筛的筛下煤泥水,采用浓缩压滤工艺,在井下安装了500m2的隔膜压滤机.由于地面和井下进行煤泥脱水的条件要求差异性和压滤机的机体庞大,使压滤机在井下的安装使用面临的难度较大,为此采取了严格的电器防爆措施,并将压滤机的机体进行主梁切割、部件拆分后运到井下进行安装调试,从而解决了压滤机井下应用的难题.进行了井下煤泥水处理的工业性试验,分析了井下使用隔膜压滤机进行煤泥脱水的影响因素,试验结果表明,此工艺的应用大幅度降低了原煤水分,使滤液水排放达到了国家一级标准.关键词:压滤机;井下;煤泥水处理中图分类号:TD462+.2文献标识码:A文章编号:1673-9787(2009)04-0436-05ApplicationofmembranefilterpressintheundergroundNO.3coalmineofJiningGAOYan-yang1,JIAOHong-guang1,JINJian-wei2(1.SchoolofMaterialScienceandEngineering,HenanPolytechnicUniversity,Jiaozuo454003,Henan,China;2.CoalAssociationofDeng-feng,Dengfeng452470,Henan,China)Abstract:Inordertotreatcoalsludgewaterunderthedehydratedscreen,craftofconcentrationandfilterpressingisadopted,and500m2membranefilterpressisinstalledinundergroundmine.Becauseofthedif-ferentconditionrequestforcarryingoutthecoalsludgedehydrationbetweengroundandunderground,andthehugebodyoffilterpress,thedifficultywillbegreatifthefilterpressisinstalledandusedinundergroundmine.Sothestrictexplosionprecautionofelectricappliancesistaken.Afterthekingpostiscutandallthepartsareresoluted,thefilterpressorganismistransportedtothemineandinstalledanddebugged.Thediffi-cultproblemthatthefilterpressisapplicatedinundergroundmineissolvedsuccessfully.Industrialexperi-mentalstudyofprocessingcoalsludgewaterisdoneunderground,andtheinfluencingfactorofusingthemembranefiltertocarryonthecoalsludgewatertreatmentisanalyzed.Theresultoftheexperimentshowsthatthecraftapplicationreduceswatercomponentofrawcoallargely,andenablesthefiltratewateremissionstoachievethenationalprimarystandard.Keywords:filterpress;undergroundmine;coalsludgewatertreatment0引言近年来,煤矿矿井水突出引起的井下煤泥水大量增加成为了影响矿井安全生产的新难题.焦作矿第28卷第4期2009年8月河南理工大学学报(自然科学版)JOURNALOFHENANPOLYTECHNICUNIVERSITY(NATURALSCIENCE)Vol.28No.4Aug.2009＊收稿日期:2009-02-04基金项目:河南省重点科技攻关项目(072302190002).作者简介:高艳阳(1985-),男,河南长垣人,从事洁净煤技术研究.E-mail:gaoyy2004@163.comDOI:10.16186/j.cnki.1673-9787.2009.04.011区九里山矿、神东矿区榆家梁矿、兖矿集团济宁三号煤矿等矿井采掘工作区先后出现过矿井水
