Nyob rau hauv cov txheej txheem ntawm cov ntaub ntawv pov tseg ntawm kev lag luam papermaking, hydrapulper yog undoubtedly cov khoom tseem ceeb. Nws ua lub luag haujlwm tseem ceeb ntawm kev rhuav tshem cov ntawv pov tseg, cov ntaub qhwv cov ntaub so ntswg thiab lwm yam khoom siv raw rau hauv cov ntaub so ntswg, tso lub hauv paus rau cov txheej txheem papermaking tom ntej.
1. Kev faib tawm thiab cov qauv tsim
(1) Kev faib tawm los ntawm Concentration
- Low-consistency hydrapulper: Qhov kev ua haujlwm tsis sib xws feem ntau yog qis, thiab nws cov qauv feem ntau yog tsim los ntawm cov khoom xws li rotors, troughs, riam hauv qab, thiab cov phaj phaj. Muaj ntau hom rotors xws li tus qauv Voith rotors thiab lub zog txuag Voith rotors. Hom kev txuag hluav taws xob tuaj yeem txuag tau 20% mus rau 30% lub zog piv nrog cov qauv qauv, thiab cov hniav tsim tau zoo dua rau cov khoom siv pulp. Lub trough feem ntau yog cylindrical, thiab qee qhov siv lub D-shaped troughs. Lub D-shaped trough ua rau lub pulp flow turbulent, lub pulping sib xws tuaj yeem ncav cuag 4% mus rau 6%, lub peev xwm ntau lawm yog ntau tshaj 30% siab dua li ntawm lub voj voos kheej kheej, thiab nws muaj thaj chaw me me, tsis tshua muaj zog thiab cov nqi peev. Cov riam hauv qab feem ntau yog detachable, ua los ntawm cov hlau muaj zog, thiab cov hniav ntug yog lined nrog cov ntaub ntawv hnav-resistant xws li NiCr steel. Txoj kab uas hla ntawm lub qhov screen ntawm lub phaj phaj yog me me, feem ntau 10-14mm. Yog hais tias nws yog siv rau kev ua lag luam pulp boards, lub qhov screen yog me me, xws li 8-12mm, uas plays lub luag hauj lwm nyob rau hauv pib sib cais loj-loj impurities.
- High-consistency hydrapulper: Kev ua haujlwm sib xws yog 10% - 15% lossis siab dua. Piv txwv li, lub rotor high-consistency tuaj yeem ua rau lub pulp tawg sib xws li 18%. Muaj turbine rotors, high-consistency rotors, thiab lwm yam. Lub turbine rotor muaj peev xwm ncav cuag lub pulp tawg sib xws ntawm 10%. Lub rotor high-consistency nce qhov chaw sib cuag nrog lub pulp thiab paub txog kev tawg los ntawm kev siv cov shearing txiav txim ntawm fibers. Cov qauv trough zoo ib yam li qhov tsis sib xws, thiab D-shaped trough kuj tau txais yuav maj mam, thiab kev ua haujlwm feem ntau yog sib quas ntus. Txoj kab uas hla ntawm qhov screen ntawm lub phaj phaj yog loj dua, feem ntau 12-18mm, thiab qhov chaw qhib yog 1.8-2 npaug ntawm qhov zoo ntawm qhov hluav taws xob qhov hluav taws xob.
(2) Kev faib tawm los ntawm cov qauv thiab kev ua haujlwm
- Raws li cov qauv, nws tuaj yeem muab faib ua kab rov tav thiab ntsug; raws li hom kev ua haujlwm, nws tuaj yeem muab faib ua ntu ntu thiab ntu. Lub ntsug nruam hydrapulper tuaj yeem tshem tawm cov impurities tsis tu ncua, nrog kev siv cov cuab yeej siv siab, muaj peev xwm ntau lawm thiab kev nqis peev tsawg; ntsug hydrapulper ntsug hydrapulper muaj kev ruaj ntseg tawg, tab sis muaj chav tsev siab zog noj thiab nws lub peev xwm ntau lawm cuam tshuam los ntawm lub sij hawm tsis tawg; kab rov tav hydrapulper tsis tshua muaj kev sib cuag nrog hnyav impurities thiab hnav tsawg dua, tab sis nws lub peev xwm ua haujlwm feem ntau me me.
2. Txoj Cai Ua Haujlwm thiab Kev Ua Haujlwm
Lub hydrapulper tsav lub pulp los ua kom muaj zog turbulence thiab mechanical shearing force los ntawm kev sib hloov ceev ntawm lub rotor, kom cov ntaub ntawv nyoos xws li cov ntawv pov tseg raug torn thiab dispersed mus rau hauv pulp. Nyob rau tib lub sij hawm, nrog kev pab los ntawm cov khoom xws li tshuaj ntsuam daim hlau thiab 绞绳 cov cuab yeej (txoj hlua reels), pib sib cais ntawm cov tawv nqaij thiab impurities, tsim cov xwm txheej rau cov txheej txheem purification thiab tshuaj ntsuam tom ntej. Cov pulper uas tsis tshua muaj siab tsom mus rau kev sib tsoo thiab kev tshem tawm thawj zaug impurity, thaum lub siab sib xws pulper ua tiav kev tawg zoo nyob rau hauv siab sib xws los ntawm muaj zog hydraulic agitation thiab kev sib txhuam ntawm fibers. Nws yog qhov tshwj xeeb tshaj yog tsim rau cov kab ntau lawm uas yuav tsum tau deinking, uas tuaj yeem ua rau tus number case yooj yim cais tawm ntawm cov fibers, thiab muaj kev tshem tawm zoo dua ntawm cov khoom kub-kua ntau dua li cov pulpers uas tsis muaj qhov sib xws.
3. Daim ntawv thov thiab qhov tseem ceeb
Hydrapulpers yog siv dav hauv cov ntawv pov tseg pulping cov kab ntau lawm thiab yog cov cuab yeej tseem ceeb rau kev paub txog kev siv cov ntawv pov tseg. Lawv cov kev ua haujlwm tau zoo tuaj yeem tsis tsuas yog txhim kho qhov kev siv ntawm cov ntawv pov tseg, txo tus nqi ntawm cov ntaub ntawv raw, tab sis kuj txo qhov kev cia siab ntawm cov ntoo nyoos, uas yog nyob rau hauv txoj kab nrog txoj kev loj hlob ntawm kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig. Ntau hom hydrapulpers tuaj yeem xaiv tau yooj yim raws li kev xav tau ntau lawm. Piv txwv li, ntsug ntsug hom tuaj yeem xaiv rau kev ua cov ntawv pov tseg nrog ntau cov impurities, thiab hom kev sib txuam siab tuaj yeem raug xaiv kom xav tau kev sib tsoo siab thiab deinking, thiaj li ua si qhov kev ua tau zoo tshaj plaws hauv cov xwm txheej ntau lawm thiab txhawb txoj kev loj hlob ntawm kev lag luam papermaking.
