Tso lus
Crystallization yog ib qho kev sib cuam tshuam uas yog qhov tseem ceeb rau kev lag luam sib txawv, los ntawm cov tshuaj mus rau kev tsim khoom noj. Ntawm nws qhov chaw, crystallization yog kev tsim cov pob zeb muaj txiaj ntsig zoo los ntawm cov lus teb lossis yaj. Thaum nws tuaj yeem ua suab ncaj, muaj ntau qhov kev tshawb fawb thiab cov txheej txheem tom qab ua tiav qhov zoo tshaj plaws crystallization. Hauv qhov kev nkag blog no, peb yuav tshawb xyuas cov txheej txheem sib txawv ntawm crystallization, nrog rau qhov tshwj xeeb tsom teeb rau ntawmCrystallization Reactor - Ib qho tseem ceeb ntawm cov iav hauv lub voj voog no.
Nkag siab txog Lub hauv paus ntawm Crystallization
Ua ntej peb poob rau hauv cov tswv yim, peb yuav tsum tshawb xyuas ib ntus seb crystallization yog dab tsi. Thaum cov khoom txav los ntawm cov kua lossis roj mus rau lub xeev cov khoom thiab tsim cov qauv siv lead ua, cov txheej txheem no hu ua crystallization. Qhov kev sib cuam tshuam no yog tswj hwm los ntawm ob yam tseem ceeb: siv lead ua kev loj hlob thiab nucleation, los yog qhov pib tsim ntawm me me siv lead ua nuclei.
Kev tswj cov kev hloov pauv no txhawm rau tsim cov khoom siv lead ua nrog qhov xav tau loj, zoo li, thiab purity yog lub hom phiaj ntawm txhua txoj kev crystallization. Lub reactor ntawm crystallization thiab lwm txoj kev tshwj xeeb thiab cov cuab yeej tuaj ua si ntawm qhov no.

Cov txheej txheem ntawm Crystallization
Muaj ntau ntau hom kev siv los ntxias thiab tswj crystallization, txhua tus nrog nws tus kheej zoo thiab kev siv. Cia peb tshawb txog qee qhov kev siv ntau tshaj plaws:
1. Txias Crystallization
Qhov no yog kab tias cov txheej txheem ncaj tshaj plaws. Nws yuav maj mam txias qhov kub, saturated tov. Raws li kev daws txias, nws lub peev xwm los tuav cov tshuaj yaj yeeb txo qis, ua rau cov muaju los ua. Txoj kev no yog siv dav hauv kev lag luam tshuaj thiab tuaj yeem ua tau zoo hauv Crystallization Reactor.
01
2. Evaporation Crystallization
Nyob rau hauv txoj kev no, cov kuab tshuaj yog maj mam evaporated los ntawm ib tug tov, ua kom lub concentration ntawm yaj tshuaj kom txog thaum nws tshaj nws solubility txwv thiab pib crystallize. Cov txheej txheem no feem ntau siv rau hauv kev tsim cov ntsev los ntawm cov dej hiav txwv.
02
3. Antisolvent Crystallization
Qhov no suav nrog ntxiv ib feem thib peb (cov tshuaj tiv thaiv) rau kev daws kom txo cov solubility ntawm lub hom phiaj, ua rau nws crystallize. Txoj kev no yog tshwj xeeb tshaj yog muaj txiaj ntsig zoo hauv kev lag luam kws tshuaj rau kev tsim cov tshuaj muaj kuab zoo siab.
03
4. Cov tshuaj tiv thaiv crystallization
Nyob rau hauv cov txheej txheem no, crystals yog tsim los ntawm ib tug tshuaj tiv thaiv. Cov khoom ntawm cov tshuaj tiv thaiv muaj qis solubility tshaj cov reactants, ua rau nws crystallize tawm ntawm cov tshuaj. Txoj kev no feem ntau siv rau hauv kev tsim cov tshuaj inorganic.
04
5. Melt Crystallization
Tsis zoo li lwm txoj kev uas pib nrog kev daws, yaj crystallization pib nrog cov khoom molten. Raws li cov yaj yog txias, muaju pib tsim. Cov txheej txheem no yog siv rau hauv kev ua kom huv ntawm cov organic tebchaw thiab hauv kev tsim khoom ntawm qee cov hlau.

Lub luag haujlwm ntawm Crystallization Reactor
Lub Crystallization Reactor yog ib qho tshwj xeeb ntawm cov cuab yeej tsim los muab kev tswj xyuas meej ntawm cov txheej txheem crystallization. Cov reactors no tuaj nyob rau hauv ntau yam qauv, tab sis txhua lub hom phiaj los tsim ib qho chaw zoo tagnrho rau kev tsim thiab kev loj hlob.
01
Lub reactor ntawm crystallization plays lub luag haujlwm tseem ceeb hauv ntau txoj kev uas peb tau tham txog. Rau kev ua kom txias crystallization, nws muab kev tswj qhov kub thiab txias los tswj tus nqi txias. Hauv evaporation crystallization, nws tuaj yeem nruab nrog lub tshuab nqus tsev kom yooj yim tshem tawm cov kuab tshuaj. Rau antisolvent thiab cov tshuaj tiv thaiv crystallization, nws muaj kev tswj kev sib xyaw ntawm cov khoom.
02
Ntxiv mus, cov reactors siab heev ntawm crystallization feem ntau suav nrog cov cuab yeej saib xyuas hauv tsev uas tso cai rau lub sijhawm taug qab ntawm cov siv lead ua thiab kev loj hlob. Cov ntaub ntawv no tuaj yeem siv los kho cov txheej txheem tsis ua haujlwm ntawm ya, ua kom cov txiaj ntsig zoo.
