Cov txiaj ntsig zoo tshaj plaws ntawm Membrane Squeeze Filter Press

Ib qho kev daws teeb meem tshiab hauv kev lag luam uas cais cov khoom khov thiab kua, lub tshuab lim dej membrane squeeze ua rau cov ncuav mog qhuav dua thiab lub sijhawm ua haujlwm sai dua li cov khoom siv lim dej ib txwm muaj. Cov thev naus laus zis no pab cov chaw tsim khoom siv hauv kev khawb av, kev kho dej khib nyiab, thiab cov chaw tsim tshuaj lom neeg txo cov nqi pov tseg thiab ua tau raws li cov qauv kev ua raws li ib puag ncig los ntawm kev siv cov diaphragms ywj pheej uas siv cov khoom siv sib zog thib ob.

Introduction

Cov kws ua haujlwm txheej txheem thiab cov thawj coj cog qoob loo hauv kev tswj hwm cov khoom siv hauv kev khawb av, kev kho cov av qias neeg hauv nroog, thiab kev tsim tshuaj lag luam ntsib teeb meem tas li: cov dej noo ntawm cov ncuav mog qab zib ua rau cov nqi pov tseg nce ntxiv, cov voj voog dewatering qeeb qeeb, thiab qhov zoo ntawm cov ncuav mog qab zib sib txawv, ua rau kev ua raws li txoj cai nyuaj. Thaum dewatering slurries lossis xav tau qhov qhuav kawg rau cov nqi landfill lossis kev ua thermal, cov tshuab nias recessed chamber ib txwm ua tsis tiav. Cov tshuab nias lim dej ob theem dewatering membrane squeeze daws cov teeb meem no. Tom qab kev lim dej ib txwm tsim cov ncuav mog qab zib, cov membrane sib xyaw ua ke inflate nrog cua compressed lossis dej kom nyem cov khoom khov 'interstitial noo noo. Cov thev naus laus zis nias lim membrane squeeze muaj xya qhov txiaj ntsig uas tau ua pov thawj uas cov pab pawg B2B nrhiav kev ua haujlwm zoo, txo nqi, thiab cov khoom siv ruaj khov yuav tsum xav txog. Kev nkag siab txog cov txiaj ntsig no pab cov neeg txiav txim siab xaiv cov txheej txheem lim dej uas ua tau raws li kev ruaj khov thiab kev them taus.

Nkag Siab Txog Lub Tshuab Lim Membrane Squeeze

Yuav Ua Li Cas Membrane Technology Txhim Kho Kev Ua Haujlwm Dewatering

Lub tshuab lim dej membrane squeeze sib xyaw ua ke cov phaj-thiab-ncej nrog cov chambers lim dej membrane squeeze nrog cov diaphragms elastomeric. Cov slurry pub nkag mus rau hauv qhov chaw nkag hauv qab kev siab, txav cov kua los ntawm cov ntaub lim thiab cov khoom khov ua ncuav mog qab zib. Hauv theem nyem, cov khoom nruab nrab inflation-feem ntau dej ntawm 1.6–3.0 MPa-nkag mus tom qab cov membranes kom nthuav dav thiab nias lub ncuav mog qab zib los ntawm ob sab tom qab cov chambers puv. Qhov kev nias tshuab no tshem tawm cov dej noo ntawm cov qauv ncuav mog qab zib txawm tias tom qab lim ntev. Nws txo cov dej noo los ntawm 10–20% piv rau cov chamber presses ib txwm muaj. Cov chambers ntim hloov pauv tuaj yeem tswj cov khoom sau ib nrab yam tsis cuam tshuam rau kev nias, uas yog qhov tseem ceeb rau kev ua cov slurries nrog cov khoom khov hloov pauv.

Qhov sib txawv ntawm Cov Khoom Siv Lim Txheem

Tsuas yog lub twj tso kua mis xwb thiaj li tsav cov kua los ntawm cov lim dej hauv cov tshuab nias recessed chamber. Kev tiv thaiv hydraulic loj hlob sai nrog lub ncuav mog qab zib tuab, ua rau qhov kawg consolidation tsis ua haujlwm zoo thiab siv sijhawm ntau. Membrane squeeze lim presses pab txo qhov teeb meem no: 80% ntawm cov khoom khov kho tshwm sim thaum lub sijhawm twj, thiab lub voj voog squeeze dewaters hauv ib feem ntawm lub sijhawm passive consolidation. Qhov sib txawv yooj yim no ua rau cov voj voog luv dua, throughput zoo dua, thiab txo qis kev siv zog ib tuj khoom qhuav.

Cov Kev Zoo Tseem Ceeb ntawm Membrane Squeeze Filter Presses

Qhov Zoo 1: Kev Ua Haujlwm Zoo Tshaj Plaws ntawm Kev Tshem Dej thiab Cov Nqi Pov Tseg Tsawg Dua 

Lub tshuab lim dej membrane squeeze nrov vim nws muaj peev xwm ziab cov ncuav mog qab zib zoo dua li cov khoom siv niaj hnub. Cov tshuab xovxwm txheem tso cov av qias neeg ntawm 70-75% dej noo hauv cov dej khib nyiab hauv nroog. Kev nias membrane ua tau raws li cov qauv kev lees txais ntawm cov chaw pov tseg yam tsis tau ziab los ntawm kev txo cov dej noo rau 55-60%. Lub kaw lus qhuav cov khoom seem hauv qab 20% dej noo, txo cov nuj nqis ntawm ib puag ncig thiab cov nqi kho vaj tse ntawm cov pas dej ntub dej hauv kev khawb av. Kev thauj mus los thiab pov tseg qhov hnyav txo qis nrog cov dej noo qis dua. Los ntawm kev txo cov dej noo ntawm ncuav mog qab zib los ntawm 70% mus rau 60%, lub chaw kho dej khib nyiab ua 50 tons ib hnub ntawm cov khoom qhuav yuav txuag tau ntau dua $ 200,000 hauv kev xa khoom thiab pov tseg. Txawm tias muaj kev siv nyiaj ntau dua li cov tshuab xovxwm ib txwm muaj, kev them rov qab nyiaj txiag yog 18-36 lub hlis.

Qhov Zoo 2: Txo Lub Sijhawm Ua Haujlwm thiab Ua Kom Muaj Zog Ntau Ntxiv

Piv rau kev lim dej ib txwm muaj, kev nias daim nyias nyias nrog lub tshuab nias lim daim nyias nyias txo lub sijhawm ua haujlwm los ntawm 20–50%. Kev nias tshuab los ntawm lub tshuab nias lim daim nyias nyias sai sai tshem tawm cov dej noo uas feem ntau xav tau kev ntws tawm tsis siv neeg, tso cai rau ntau pawg txhua qhov hloov pauv yam tsis muaj peev xwm nce. Qhov kev txuag sijhawm no ua rau cov khoom tsim tawm txhua xyoo los ntawm cov khoom siv uas twb muaj lawm hauv kev tsim tshuaj lom neeg, qhov twg qhov ceev ntawm kev tig rov qab los ntawm ib pawg mus rau ib pawg cuam tshuam rau lub sijhawm tsim khoom. Cov nqi zog thiab lub zog qis dua ib pawg thiab tuj ua tiav yog los ntawm lub voj voog luv dua nrog lub tshuab nias lim daim nyias nyias. Nrog tsawg dua cov chav nias, cov neeg ua haujlwm tuaj yeem ua tau raws li kev xa khoom txhua hnub lossis tsim cov khoom tsim tawm yam tsis muaj kev nqis peev. Kev ua tiav sai dua thiab kev tso tawm qhuav dua ua rau lub tshuab nias lim daim nyias nyias muaj txiaj ntsig zoo rau kev ua haujlwm uas txwv qhov chaw lossis kev tsim kho vaj tse.

Qhov Zoo 3: Kev Ntxuav Ncuav Mog Qab Zib Zoo Dua thiab Kev Huv Si ntawm Cov Khoom

Tshem tawm cov dej cawv niam tawm ntawm lub ncuav mog qab zib lim kom ntseeg tau tias cov khoom huv si hauv cov tshuaj lom neeg zoo thiab cov tshuaj siv. Channeling tshwm sim hauv cov tshuab nias txheem thaum cov kua ntws los ntawm cov kab nrib pleb es tsis yog lub ncuav mog qab zib. Kev nias membrane nias lub ncuav mog qab zib, kaw cov channel no thiab faib cov kua ntxuav hla cov khoom me me. Qhov kev ua kom zoo dua no txo ​​​​​​kev siv dej los ntawm 40% thiab tshem tawm cov khoom tsis huv zoo dua. Cov ntsev seem ua rau cov xim zoo dua hauv cov xim thiab cov xim sib xyaw, tab sis kev ntxuav membrane tso cai rau cov neeg tsim khoom ua tiav cov qauv kev huv si yam tsis tas siv dej tsis tsim nyog lossis cov voj voog ntxuav. Lub kaw lus kuj tseem muaj kev ntxuav countercurrent, uas siv cov dej cawv huv dua los ua kom zoo dua qhov kev hloov pauv ntawm cov khoom tsis huv nrog dej ntxuav tsawg dua.
