隔膜式压滤机在济三煤矿井下的应用高艳阳

高艳阳1,焦红光1,靳建伟2(,　454003;2.,　452470)＊: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.　　:压滤机;井下;煤泥水处理:TD462+.2　:A　:1673-9787(2009)04-0436-05ApplicationofmembranefilterpressintheundergroundNO.3coalmineofJiningGAOYan-yang1,JIAOHong-guang1,JINJian-wei2(1.SchoolofMaterialScienceandEngineering,HenanPolytechnicUniversity,Jiaozuo　454003,Henan,China;2.CoalAssociationofDeng-feng,Dengfeng　452470,Henan,China)Abstract:Inordertotreatcoalsludgewaterunderthedehydratedscreen,craftofconcentrationandfilterpressingisadopted,and500m2membranefilterpressisinstalledinundergroundmine.Becauseofthedif-ferentconditionrequestforcarryingoutthecoalsludgedehydrationbetweengroundandunderground,andthehugebodyoffilterpress,thedifficultywillbegreatifthefilterpressisinstalledandusedinundergroundmine.Sothestrictexplosionprecautionofelectricappliancesistaken.Afterthekingpostiscutandallthepartsareresoluted,thefilterpressorganismistransportedtothemineandinstalledanddebugged.Thediffi-cultproblemthatthefilterpressisapplicatedinundergroundmineissolvedsuccessfully.Industrialexperi-mentalstudyofprocessingcoalsludgewaterisdoneunderground,andtheinfluencingfactorofusingthemembranefiltertocarryonthecoalsludgewatertreatmentisanalyzed.Theresultoftheexperimentshowsthatthecraftapplicationreduceswatercomponentofrawcoallargely,andenablesthefiltratewateremissionstoachievethenationalprimarystandard.Keywords:filterpress;undergroundmine;coalsludgewatertreatment0　　,.28420098　　()JOURNALOFHENANPOLYTECHNICUNIVERSITY(NATURALSCIENCE)　　Vol.28　No.4Aug.2009＊　　:2009-02-04　　:(072302190002).　　:(1985-),,,.　　E-mail:[e-mail]:10.16186/j.cnki.1673-9787.2009.04.011、、[1].,,,.,,,[2].,,[3],.,.500t,、,,,.,,2006.,,,,XSKG,,、、,,,.,.1　1.1　,.,,;,,,.1.2　6304.,,179.13t/h,,25.04t/h.,,600t,.6.15,,,.0～1mm,,150g/L,0.3mm9.5m3/m2·h.154.09t/h,25.04t/h,1.5g/cm3,146.70g/L,0.9m3/m2·h.,0.1mm(0.1mm),,.20081,,:,,,,119,.1.3　、、.,.,、,、,,(437　4　　　　　　　　　　　,:20%～24%),(0.1g/L).:(1),,,.(2),,,.(3)、,,.(4),,.,,:(1),,,.(2)、,,,、、.(3)、、,,.(4),,、、[4].(5),,[5].(6),、.1.4　,,,.,:(1),500m2,,500m2.,,.(2),.(3),.,..1.5　1.5.1　压滤空间的布置20082,,,,,.,,.,,、、,.1.5.2　防爆性能设计,,.,、.1.5.3　压滤机的运输安装20084,.,,2,、、、.,,..、,,、,,438()　　　　　　　　　　　　200928　、,,.20085、,.1.6　1.6.1　压滤机的结构和　　　主要技术参数,.,500m2XSKG,1..　　　　　:500m2;　　　　　　　　　:25MPa;:10m2;:31.5MPa;:1500mm×1500mm;:5.5kW;:≤0.7MPa;:;:≤0.8MPa;:25min;:5m3;:12m3.1.6.2　压滤机的工作原理,.,,,,,.,,.,,,(),,,.,,,,,,.,[6].2　20086,.,.,.2.1　、、、、,、.(1).,,.,400～500g/L,600g/L,300g/L.(2).,.0～0.5mm,-200.-200,,.,,,.,,,,,439　4　　　　　　　　　　　,:,.(3)..,,.,,,,,,.(4)..,,,.,,.0.6MPa.(5)..,,.,,,.80～120m3/h.2.2　,:(1)400g/L,5m3,20min.,20h,1d300m3.(2),300g/L,40min,20%.、,、.500g/L,15min,19%.(3),4.5kg,18%～20%,4.1kg,22%～24%.,.(4)19.7%,8.1,17mmg/L,100mg/L.3　　、、,XSKG,.(1)XSKG,,、.(2),6%～8%,;,,.(3),,、、.:[1]　.[J].,2008,14(2):98-101.[2]　,,.[M].:,2002.[3]　.[J].,2001,32(4):27-28.[4]　,.[J].,2007(1):12-14.[5]　.[M].:,2007.[6]　.[M].:,2001.(责任编辑　宫福满)440()　　　　　　　　　　　　200928
