Pulp Concentration Measurement
Lub pulp concentration nyob rau hauv lub hauv siab tshuab nce mus txog 2.5-3.5% feem ntau. Dej yuav tsum tau dilute lub pulp mus rau qis concentration rau zoo-dispersed fibers thiab impurity tshem tawm.
Raufourdrinier tshuab, lub pulp concentration nkag mus rau hauv lub mesh yog 0.3-1.0% nyob rau hauv raug raws li lub pulp yam ntxwv, khoom siv, thiab ntawv zoo. Nyob rau theem no, theem ntawm dilution sib haum mus rau qhov xav tau ntawm cov ntaub so ntswg ntawm lub mesh, lub ntsiab lus tib lub ntsiab lus yog siv rau kev ua kom huv, pom, thiab tsim ntawm lub mesh.
Lub pulp concentration ntawm mesh yog qis dua rau 0.1-0.3% tsuas yog rau lub tog raj kheej tshuab. Flow tus nqi los ntawm kev ua kom huv thiab pom yog siab dua li qhov yuav tsum tau muaj xws li cov kua qaub qis. Tsis tas li ntawd, yuav tsum muaj kev lim dej ntau dua thiab pom cov khoom siv los ua cov khoom siv qis qis, xav tau ntau lub peev, qhov chaw loj dua, cov kav dej ntau dua, thiab siv zog ntau dua.
Lub tog raj kheej tshuab feem ntau txais yuav aob-theem dilution txheej txheem,nyob rau hauv uas cov concentration yog txo qis rau 0.5 ~ 0.6% ua ntej rau kev lim dej ua ntej thiab pom; tom qab ntawd txo qis rau lub hom phiaj concentration ntxiv ua ntej nkag mus rau hauv mesh hauv stabilizing lub thawv.
Pulp dilution siv dej dawb los ntawm cov mesh nyob rau hauv ib txwm rau kev txuag dej thiab rov qab zoo fibers, muab tub lim, thiab tshuaj los ntawm cov dej dawb. Cov dej dawb rov qab muaj txiaj ntsig zoo rau kev txuag hluav taws xob rau cov cav tov uas xav tau cov cua sov pulp.
Yam tseem ceeb cuam tshuam rau Diluted Pulp Concentration
Variations nyob rau hauv Pulp Concentration nkag mus rau hauv Regulating Box
Kev hloov pauv hauv qhov sib xws los ntawm kev ntaus los yog kev hloov pauv hauv lub cev tawg tuaj yeem ua rau muaj kev hloov pauv hauv cov pulp concentration. Kev tsis zoo nyob rau hauv lub hauv siab tshuab tuaj yeem ua rau lub siab tsis sib haum xeeb nyob hauv ntau qhov chaw, ua rau muaj kev tsis ruaj khov ntxiv.
Backflow ntawm Rejects hauvPurification thiablim
Kev tsis lees paub los ntawm kev lim dej thiab lim dej feem ntau yog rov ua dua rau hauv qhov system nrog cov dej dilution. Variations nyob rau hauv lub ntim thiab concentration ntawm qhov kev tsis lees paub yog nyob ntawm qhov ua tau zoo ntawm cov khoom siv purification thiab filtration thiab cov kua theem ntawm lub twj tso kua mis inlets.
Cov kev hloov no ua rau muaj kev cuam tshuam rau cov dej dawb concentration siv rau dilution thiab, nyob rau hauv lem, qhov kawg pulp concentration. Cov teeb meem zoo sib xws tuaj yeem tshwm sim hauv cov tshuab xa rov qab ntawm lub tog raj kheej tshuab hla lub tank.
Variations nyob rau hauv diluted pulp concentration tuaj yeem cuam tshuam rau ob qho tib si kev ua haujlwm ntawm daim ntawv tshuab thiab daim ntawv kawg. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tsum tau saib xyuas cov pulp concentration nrogsib xws meter pulptsim los ntawmLonnmeterthaum lub sij hawm ntau lawm thiab kho cov inflow mus rau lub regulating lub thawv kom ruaj khov concentrations. Cov tshuab ntawv niaj hnub feem ntau siv cov cuab yeej siv hluav taws xob rau:
- Automatically kho covpulp concentrationnkag mus rau lub regulating box.
- Kho cov inflow raws li kev hloov pauv hauv daim ntawv hnyav thiabheadbox pulp concentration.
Qhov no ua kom lub siab ruaj khov ntawm cov tawv nqaij.
Cov txiaj ntsig ntawm Concentration Adjustment rau Diluted Pulp
Concentration tswj ntawm diluted pulp pab rau ob qho tib si pom kev ua hauj lwm ntawm daim ntawv tshuab thiab daim ntawv zoo tswj.
Rau lub tog raj kheej Machine
Thaum cov pulp muaj qhov qis qis thiab dewaters sai, cov dej sab hauv thiab sab nraud hauv ntu mesh raug txo, ua rau tsis muaj zog ntawm daim ntawv txheej rau mesh. Qhov no ua rau kom cov nyhuv concentration, txo cov dej ntws tawm, thiab ua rau kom qhov sib txawv ntawm qhov sib txawv ntawm cov pulp thiab mesh, ua rau cov ntawv tsis sib xws.
Txhawm rau hais txog qhov no, kev siv dej dawb yog nce ntxiv kom txo qis ntawm cov kua txiv hmab txiv ntoo, ua kom tus nqi ntws mus rau mesh. Qhov no nce qhov sib txawv ntawm cov dej, nce dej ntws, txo cov teebmeem concentration, thiab txo qhov sib txawv ceev, yog li txhim kho daim ntawv sib xws.
Rau Fourdrinier Machinery
Kev sib ntaus sib tua siab ua rau cov dej tsis yooj yim, txuas ntxiv cov kab dej, ua kom cov dej noo hauv cov ntawv ntub dej, thiab ua rau embossing lossis crushing thaum nias. Daim ntawv nro thoob plaws lub tshuab txo, thiab shrinkage thaum ziab nce, ua rau muaj qhov tsis xws luag xws li folds thiab wrinkles.
Txhawm rau kov yeej cov teeb meem no, diluted pulp concentration tuaj yeem nce ntxiv los ntawm kev txo qis kev siv dej dawb, txo cov dej ntws tawm.
Hloov pauv, yog tias qhov kev ntaus nqi qis qis, fibers zoo li flocculate, thiab cov kua dej tshwm sim sai dhau ntawm cov mesh, cuam tshuam rau daim ntawv sib xws. Nyob rau hauv cov ntaub ntawv no, kev siv dej dawb ntxiv kom txo cov diluted pulp concentration tuaj yeem txo qis flocculation thiab txhim kho uniformity.
Xaus
Dilution yog ib qho tseem ceeb ua haujlwm hauv papermaking. Hauv kev tsim khoom, nws yog qhov tseem ceeb rau:
- Ua tib zoo saib xyuas thiab nruj me ntsis tswj cov kev hloov pauv hauv dilutedpulp concentrationkom muaj kev ruaj ntseg ua haujlwm.
- Ua tib zoo saib xyuas cov kev hloov ntawm cov khoom zoo thiab kev ua haujlwmthiab, thaum tsim nyog, kho pulp concentration raws li lub cuab yeej los kov yeej cov teeb meem zoo li cov uas tau hais los saum no.
Los ntawm kev tswj cov pulp dilution zoo, ruaj khov ntau lawm, cov ntawv zoo, thiab kev ua haujlwm zoo tuaj yeem ua tiav.
