Kev Ntsuas Qhov Ntsuas Ntawm Cov Nqaij Npuas
Feem ntau, cov pulp concentration hauv lub tshuab ua haujlwm ncav cuag 2.5–3.5%. Yuav tsum muaj dej los dilute cov pulp kom qis dua rau cov fibers uas tawg zoo thiab tshem tawm cov impurity.
Raucov tshuab plaub lub tshuab, qhov concentration ntawm cov pulp uas nkag mus rau hauv lub mesh yog 0.3–1.0% raws li cov yam ntxwv ntawm cov pulp, cov khoom siv, thiab cov ntawv zoo. Nyob rau theem no, qib ntawm kev dilution sib raug rau qhov concentration ntawm cov pulp uas xav tau ntawm lub mesh, txhais tau tias tib qhov concentration yog siv rau kev ntxuav, kev lim dej, thiab kev tsim ntawm lub mesh.
Qhov concentration ntawm cov pulp ntawm lub mesh qis dua li 0.1–0.3% tsuas yog rau cov tshuab kheej kheej xwb. Qhov nrawm ntawm kev ntxuav thiab lim dej yog siab dua li qhov xav tau nrog cov pulp uas muaj concentration tsawg. Ntxiv mus, xav tau ntau cov khoom siv ntxuav thiab lim dej kom ua tiav cov pulp uas muaj concentration tsawg, xav tau ntau peev, qhov chaw loj dua, cov kav dej nyuaj dua, thiab kev siv hluav taws xob ntau dua.
Cov tshuab raj kheej feem ntau siv atxheej txheem dilution ob theem,nyob rau hauv uas qhov concentration yog txo qis rau 0.5 ~ 0.6% ua ntej rau kev ntxuav ua ntej thiab lim; ces txo qis rau lub hom phiaj concentration ntxiv ua ntej nkag mus rau hauv mesh hauv lub thawv stabilizing.
Kev siv dej dawb los ntawm cov ntaub mesh los ua kom cov dej huv thiab rov qab tau cov fibers zoo, cov khoom siv ntxiv, thiab cov tshuaj los ntawm cov dej dawb. Kev siv dej dawb los ua kom cov dej dawb rov qab tau zoo yog qhov zoo rau kev txuag hluav taws xob rau cov tshuab uas xav tau cua sov cov ntaub.
Cov Yam Tseem Ceeb Uas Cuam Tshuam Rau Qhov Kev Ntsuas Ntawm Cov Nqaij Qhuav
Kev Hloov Pauv Hauv Kev Ntsuas Pulp Nkag Mus Rau Hauv Lub Thawv Tswj
Qhov kev hloov pauv ntawm qhov sib xws los ntawm kev ntaus lossis kev hloov pauv ntawm lub kaw lus tawg tuaj yeem ua rau muaj kev hloov pauv ntawm cov pulp concentration. Kev ncig tsis zoo hauv lub thawv tshuab tuaj yeem ua rau muaj kev sib txawv ntawm cov pulp concentration thoob plaws ntau qhov chaw, ua rau muaj kev tsis ruaj khov ntxiv.
Kev Rov Qab Los ntawm Kev Tsis lees txaiss nyob rau hauvKev ntxuav thiabkev lim dej
Cov khoom pov tseg uas tau los ntawm kev ntxuav thiab lim dej feem ntau raug rov qab muab tso rau hauv lub kaw lus nrog cov dej uas tau diluted. Kev hloov pauv ntawm qhov ntim thiab qhov concentration ntawm cov khoom pov tseg no nyob ntawm kev ua haujlwm ntawm cov khoom siv ntxuav thiab lim dej thiab cov kua dej ntawm cov qhov nkag ntawm lub twj tso kua mis.
Cov kev hloov pauv no ua rau muaj kev cuam tshuam rau qhov concentration ntawm cov dej dawb uas siv rau kev dilution thiab, ua rau, qhov concentration ntawm cov pulp kawg. Cov teeb meem zoo sib xws tuaj yeem tshwm sim hauv cov kab ke rov qab ntawm lub tshuab lub tog raj kheej overflow tanks.
Kev hloov pauv ntawm cov kua txiv hmab txiv ntoo uas tau diluted tuaj yeem cuam tshuam rau ob qho kev ua haujlwm ntawm lub tshuab ntawv thiab qhov zoo ntawm daim ntawv kawg. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tsum saib xyuas cov kua txiv hmab txiv ntoo kom zoo nroglub ntsuas kev sib xws ntawm pulptsim los ntawmLonnmeterthaum lub sijhawm tsim khoom thiab kho qhov ntws mus rau lub thawv tswj kom tswj tau qhov sib xyaw kom ruaj khov. Cov tshuab ntawv niaj hnub feem ntau siv cov cuab yeej siv tsis siv neeg los:
- Kho qhovkev sib sau ua ke ntawm cov pulpnkag mus rau hauv lub thawv tswj hwm.
- Kho qhov ntws los ntawm kev hloov pauv ntawm qhov hnyav ntawm daim ntawv thiablub taub hau pulp concentration.
Qhov no ua kom muaj qhov ruaj khov ntawm cov pulp.
Cov txiaj ntsig ntawm kev kho qhov concentration rau cov kua txiv hmab uas tau diluted
Kev tswj hwm qhov concentration ntawm cov kua txiv hmab txiv ntoo diluted pab tau rau kev ua haujlwm zoo tshaj plaws ntawm lub tshuab ntawv thiab kev tswj xyuas zoo ntawm daim ntawv.
Rau Cov Tshuab Kheej Kheej
Thaum cov pulp muaj qhov ntaus qis thiab cov dej tawm sai sai, cov dej sab hauv thiab sab nraud hauv ntu mesh raug txo qis, ua rau cov ntawv txuas rau ntawm mesh tsis muaj zog. Qhov no ua rau muaj kev sib sau ua ke ntau dua, txo cov dej ntau dhau, thiab ua rau qhov sib txawv ntawm cov pulp thiab mesh nce ntxiv, ua rau cov ntawv tsis sib xws.
Yuav kom daws tau qhov teeb meem no, kev siv dej dawb raug nce ntxiv kom txo qhov concentration ntawm cov pulp, ua rau cov dej ntws mus rau hauv mesh ntau dua. Qhov no ua rau qhov sib txawv ntawm cov dej nce siab, ua rau cov dej ntws ntau dua, txo cov teebmeem ntawm cov concentration, thiab txo qhov sib txawv ntawm qhov ceev, yog li ua kom cov ntawv sib xws.
Rau Cov Tshuab Plaub Drinier
Cov qib siab ntawm kev ntaus ntawv ua rau cov dej ntws nyuaj, ua rau cov kab dej ntev dua, ua rau cov ntawv ntub dej ntau ntxiv, thiab ua rau cov ntawv embossing lossis tsoo thaum nias. Cov ntawv nruj ntawm lub tshuab txo qis, thiab cov ntawv me me thaum lub sijhawm ziab nce ntxiv, ua rau muaj qhov tsis zoo xws li cov kab thiab cov kab ntxhib.
Yuav kom kov yeej cov teeb meem no, cov kua txiv hmab uas tau diluted tuaj yeem nce ntxiv los ntawm kev txo cov dej dawb siv, txo cov teeb meem ntws tawm.
Ntawm qhov tod tes, yog tias qib kev ntaus qis, cov fibers feem ntau yuav flocculate, thiab cov dej ntws tawm sai dhau ntawm lub mesh, cuam tshuam rau daim ntawv sib npaug. Hauv qhov no, kev siv dej dawb ntau ntxiv kom txo qhov concentration ntawm cov pulp diluted tuaj yeem txo qhov flocculation thiab txhim kho qhov sib npaug.
Xaus lus
Kev dilution yog ib qho tseem ceeb hauv kev ua ntawv. Hauv kev tsim khoom, nws yog ib qho tseem ceeb rau:
- Saib xyuas thiab tswj hwm cov kev hloov pauv hauv cov khoom sib xyawkev sib sau ua ke ntawm cov pulpkom ntseeg tau tias kev ua haujlwm ruaj khov.
- Ua tib zoo saib xyuas cov kev hloov pauv ntawm cov khoom zoo thiab cov xwm txheej ua haujlwmthiab, thaum tsim nyog, kho qhov concentration ntawm cov pulp ua ib qho cuab yeej los kov yeej cov teeb meem zoo li cov uas tau hais los saum toj no.
Los ntawm kev tswj hwm kev sib xyaw ntawm cov pulp kom zoo, kev tsim khoom ruaj khov, daim ntawv zoo, thiab kev ua haujlwm zoo tshaj plaws tuaj yeem ua tiav.
