Khoom Description
Kev sib xyaw ntawm cov khoom siv hmoov yog dav siv hauv kev tsim khoom, ua rau kev sib xyaw ntawm cov khoom siv hmoov ua lub luag haujlwm tseem ceeb hauv kev tsim khoom. Piv txwv li, hauv kev tsim cov khoom noj, cov chiv ua liaj ua teb, cov ntaub ntawv ceramic thiab tshuaj, cov khoom sib txawv lossis cov khoom sib txawv yuav tsum tau muab sib xyaw ua ke hauv ib qho kev faib ua feem, thiab tom qab ntawd los ntawm qee cov txheej txheem ua tiav, cov khoom kawg tau txais. Thaum lub sij hawm tsim cov txheej txheem, seb qhov kev faib ntawm cov hmoov yog ib yam ncaj qha cuam tshuam rau qhov kawg ntawm cov khoom.
Cov khoom sib xyaw
Cov khoom sib xyaw yog hais txog qhov kev hloov ntawm txoj hauj lwm thiab qhov nrawm ntawm ob lossis ntau qhov hais raws li qhov kev txiav txim ntawm ib qho kev quab yuam sab nraud (txheej txheem quab yuam lossis lub ntiajteb txawj nqus), thiab los ntawm kev sib txheeb ntawm cov khoom thiab kev sib nrig sib infiltration rau ib leeg particle aggregates, nws tsim cov txheej txheem nyuaj ntawm ntau qhov sib xyaw ua ke. Yog li ntawd, nws ua rau cov khoom ntawm txhua yam yuav tsum tau faib uniformly. Vim lub macroscopic continuity thiab microscopic discreteness ntawm cov hais, cov khoom sib txawv ntawm cov khoom nthuav tawm cov txheej txheem chaotic heev thaum lub sij hawm sib xyaw ua ke ntawm cov txheej txheem disperse.
Mixing mechanism
Txawm hais tias tus txheej txheem ntawm kev sib xyaw hmoov cov ntaub ntawv yog complex thiab intricate, nws tseem ua raws li qee cov cai. Raws li kev sib xyaw ua ke, kev sib xyaw tuaj yeem muab faib ua peb hom: kev sib xyaw ua ke, sib tov sib xyaw, thiab sib tov sib xyaw. Txawm hais tias peb txoj kev sib xyaw ua ke no txuas ntxiv mus rau lub sijhawm, hauv kev xyaum, nws feem ntau ntseeg tias kev sib xyaw ntawm cov khoom sib xyaw yog qhov tshwm sim ntawm kev sib xyaw ua ke ntawm peb qhov kev sib xyaw ua ke, thiab lawv sib tshuam nrog ib leeg.
Peb ua ke mechanisms
Convection sib tov
Convection mixing yog hais txog qhov tshwm sim uas cov khoom raug xa mus rau sab nraud quab yuam, ua rau cov khoom sib txawv ntawm cov khoom sib txawv mus rau qhov chaw tseem ceeb hauv qhov chaw. Qhov kev sib xyaw no tau ua tiav los ntawm sab nraub qaum - thiab - ntws tawm ntawm ib tus neeg, thiab nws feem ntau yog khaus heev tab sis muaj sijhawm luv. Qhov tshwm sim ntawm qhov kev sib xyaw no yog tias cov khoom sib cais maj mam ua uniformly faib.
(2) Shearing sib tov
Shear mixing yog tshwm sim los ntawm tus txheeb ze zawv zawg ntawm dispersed hais. Vim muaj qhov sib txawv ntawm txhua qhov sib txawv, shear mixing plays lub luag haujlwm tseem ceeb hauv kev ua haujlwm kneading.
(3) Kev sib xyaw ua ke
Feem ntau hais lus, qhov sib xyaw hauv zos uas tshwm sim ntawm cov khoom nyob ib sab ntawm qib microscopic hu ua diffusion mixing. Raws li kev cuam tshuam ntawm kev quab yuam sab nraud, txoj haujlwm ntawm cov khoom uas nyob ib sab hloov pauv, ua rau muaj kev sib nkag siab thiab sib xyaw ntawm cov khoom. Thaum qhov sib tov mus txog rau theem diffusion mixing, nws tau txiav txim siab tias kev sib xyaw ua tiav tiav.
Kev sib tov
Cov txheej txheem ntawm kev sib xyaw tuaj yeem muab faib ua peb theem: theem ntawm kev sib xyaw ua ke, theem uas cov convective thiab shear rog ua ke, thiab theem uas convective thiab shear rog ua haujlwm ntawm nws tus kheej.
Diffusion thiab mixing theem.
Theem 1: Lub hom phiaj tseem ceeb ntawm kev sib xyaw hauv theem no yog kev sib xyaw ua ke, thiab kev sib tov nrawm heev.
Theem Ob: Cov theem no muaj kev sib koom ua ke ntawm convection thiab shear. Lub sijhawm sib tov yog luv luv.
Ntev.
Theem 3: Cov theem no yog lub diffusion mixing theem, thaum lub sij hawm lub xeev ntawm cov sib tov nyob rau hauv ib tug equilibrium ntawm sib tov thiab sib cais.
Lub xeev yog xws li cov homogeneity fluctuates nyob ib ncig ntawm ib tug tej yam nqi.
Kev sib xyaw ntawm cov hmoov nplej
Yuav kom ua tiav cov homogenization ntawm cov hmoov av, sab nraud quab yuam xws li cov neeg kho tshuab lossis cov kua dej yuav tsum tau siv. Cov khoom siv ntawm cov hmoov hmoov tuaj yeem raug suav hais tias yog "dispersion" thiab "motion". Tus qub yog hais txog kev tawg ntawm cov khoom sib txawv, qhov loj me, thiab cov duab, thaum lub sijhawm tom kawg yog hais txog kev txav mus los, kev hloov pauv, thiab kev sib tsoo. Thaum siv lub paddle rau forcefully homogenize hmoov hais, muaj ntau yam uas cuam tshuam rau homogenization ntawm cov hmoov hais, xws li cov khoom ntawm cov hmoov, cov qauv ntawm lub tshuab sib tov, cov txheej txheem tsis, thiab qhov chaw sib xyaw. Kev paub qhia tau hais tias txhua qhov kev hloov pauv ntawm ib qho ntawm cov xwm txheej no tuaj yeem muaj kev cuam tshuam loj rau cov txheej txheem homogenization thiab cuam tshuam.
Tshawb nrhiav kev sib xyaw cov cuab yeej
Kev ua haujlwm ntawm cov cuab yeej sib xyaw yog kom moisten thiab homogenize cov ntaub ntawv raw khoom, ua tau raws li qhov yuav tsum tau muaj ntawm cov khoom sib xyaw thiab cov ntsiab lus noo noo tsim nyog, yog li tsim cov xwm txheej rau cov khoom zoo. Tam sim no, kev tshawb fawb ntawm cov qauv thiab kev ua tau zoo ntawm cov khoom sib tov tsis yog tsuas yog tsom rau kev tshawb fawb ntawm kev sib xyaw thiab cov qauv ntawm cov khoom sib tov, tab sis kuj tseem them nyiaj rau kev cuam tshuam ntawm cov khoom siv ntawm nws cov khoom sib xyaw, xws li particle loj, cov khoom zoo, cov ntsiab lus ntawm cov khoom, thiab lwm yam, nrog rau kev cuam tshuam ntawm kev sib tov lub sij hawm thiab cov khoom ntim ntawm kev sib tov.
Muaj ntau hom hmoov sib tov khoom. Raws li cov qauv siv hluav taws xob, cov cuab yeej sib xyaw tuaj yeem muab faib ua cov khoom sib xyaw nrog cov sib xyaw ua ke thiab cov uas tsis muaj qhov sib xyaw. Raws li daim ntawv layout ntawm lub tshuab sib tov, nws tuaj yeem muab faib ua kab rov tav thiab ntsug mixers. Raws li hom kev ua haujlwm ntawm lub tshuab sib xyaw, nws tuaj yeem raug cais raws li qhov ruaj khov - lub cev hom thiab txav - lub cev hom. Hauv kev tsim khoom tiag tiag, nws yog qhov tsim nyog los tsim cov khoom sib tov nrog ntau yam khoom sib xyaw ua ke raws li qhov yuav tsum tau ua. Qhov loj ntawm lub tov khoom, qhov teeb tsa ntawm lub stirrer, cov yam ntxwv ntawm cov hniav, thiab qhov kev ncua deb ntawm lub stirrer thiab hauv qab ntawm lub tog raj kheej tag nrho txiav txim nws tus yam ntxwv.
