Crystallizer yog dab tsi?
Crystallization yog ib qho txheej txheem hauv kev lag luam chemical uas cuam tshuam nrog nag lossis daus ntawm cov tshuaj yaj yeeb los ntawm kev daws los ntawm kev ua kom txias, evaporation, lossis tshuaj tiv thaiv. Cov khoom uas tsim thaum lub sij hawm crystallization yog hu ua crystals, thiab lawv muaj ib tug txhais cov duab, qhov loj, thiab muaj pes tsawg leeg nyob ntawm seb cov xwm txheej ntawm cov txheej txheem. Crystals muaj ntau yam kev siv, los ntawm cov kws kho mob thiab cov khoom noj khoom haus ntxiv rau cov khoom siv hluav taws xob thiab cov khoom siv, thiab lawv qhov zoo yog qhov tseem ceeb rau lawv cov kev ua tau zoo.
Taw qhia txog kev daws teeb meem:Cov tshuaj uas muaj cov kuab tshuaj kom crystallized yog nkag mus rau hauv cov hlab ntsha crystallizer.
Cua sov qhov kev daws teeb meem:Cov tshuaj yog rhuab siv chav los yog dej kub nyob rau hauv lub cua sov coils los yog lub tsho nyob ib ncig ntawm lub crystallizer hlab ntsha. Thaum cov tshuaj heats li, cov kuab tshuaj pib evaporate.
Nce Solvent Concentration:Raws li cov kuab tshuaj evaporates, cov kuab tshuaj yuav ntau concentrated nyob rau hauv cov tshuaj, ua rau supersaturation. Qhov no txhais tau hais tias qhov kev daws teeb meem ua kom muaj zog ntau dua nrog cov kuab tshuaj ntau dua li qhov nws yuav nyob ntawm qhov sib npaug hauv ib txwm muaj.
Nucleation:Thaum cov tshuaj mus txog qhov tseem ceeb ntawm supersaturation, nucleation tshwm sim. Nucleation yog thawj tsim ntawm cov pob zeb me me hauv cov tshuaj.
Crystal Loj hlob
Nrog rau lub xub ntiag ntawm noob muaju los yog kev pab los ntawm ib tug agitator, cov nucleated crystals loj hlob nyob rau hauv loj raws li ntau cov ntsiab lus txuas rau lawv.
Kev sib cais ntawm Crystals
Raws li cov txheej txheem crystallization zuj zus, cov crystals txuas ntxiv mus txog thaum lawv ncav cuag qhov loj me. Tom qab ntawd cov crystals tau muab cais tawm ntawm cov tshuaj ntxiv uas siv cov txheej txheem sib cais.
