Stainless hlau DTB crystallizer-txhim kho cov ntsiab lus
Lub DTB crystallizer yog siv lead ua slurry sab hauv kev ncig crystallizer. Nws cov yam ntxwv zoo ib yam yog tias muaj cov stirrers, coj cov raj thiab cov baffles hauv cov crystallizer, nrog rau cov khoom siv sib hloov cua sov thiab cov khoom siv siv lead ua zoo tshem tawm.
Cov kua siv lead ua kua slurry nce los ntawm hauv qab ntawm lub puab qhia raj los ntawm lub built-in stirrer, thiab kev sib cuag nrog cheeb tsam nrog ntau dua supersaturation ntawm cov kua nto kom haus lub supersaturation. Tom qab ntawd nws nqis los ntawm thaj chaw annular hauv cheeb tsam nruab nrab ntawm cov raj qhia sab hauv thiab cov raj qhia sab nraud. Ntawm qhov sib txawv ntawm qhov sib txawv ntawm lub tog raj kheej crystallizer thiab cov raj qhia sab nraud, cov kua siv lead ua kua slurry thiab cov kua ntshiab tau sib cais, thiab cov kua siv lead ua kua slurry txuas ntxiv mus. Cov kua dej ntshiab nkag mus rau hauv cov khoom siv siv lead ua zoo tshem tawm los ntawm qhov sib txawv ntawm qhov sib txawv kom yaj cov khoom siv lead ua zoo tshaj plaws, uas ua kom ntseeg tau tias cov siv lead ua nuclei yuav tsis dhau, ua rau qhov loj me me ntawm cov muaju sib txawv.
Nyob rau hauv cov txheej txheem evaporation crystallization, tus nqi ntawm supersaturation tiam nyob ntawm tus nqi evaporation, uas yog, evaporation siv ntawm cov khoom siv. Qhov ntau dua qhov evaporation siv, qhov ceev ntawm supersaturation yog generated, thiab qhov yooj yim dua nws yog tsim ib tug heev supersaturation. Kev tshem tawm ntawm supersaturation feem ntau yog nyob ntawm tus kheej nucleation thiab kev loj hlob ntawm cov siv lead ua.
Yog tias muaj cov khoom siv lead ua kom txaus thiab qhov kev loj hlob sai hauv cov crystallizer, lub supersaturation tsim los ntawm evaporation tuaj yeem loj hlob tag nrho ntawm cov khoom siv lead ua, thiab qhov supersaturation ntawm cov tshuaj yuav tsis tshaj qhov loj supersaturation ntawm cov tshuaj, yog li ntawd lub solute yuav tsis. tshem tawm cov supersaturation los ntawm cov txheej txheem nucleation, thiab yog li ntau tus siv lead ua nuclei yuav tsis raug tsim tawm.
Yog tias tsis muaj cov khoom siv lead ua tsis txaus hauv cov tshuaj, qhov kev loj hlob ntawm cov siv lead ua tsis txaus los tshem tawm cov supersaturation generated los ntawm evaporation, yog li ntawd lub supersaturation ntawm cov tshuaj yog siab heev thiab nyob rau hauv ib qho chaw tsis ruaj khov. Lub supersaturation ntawm cov tshuaj yuav haus lub supersaturation los ntawm spontaneous nucleation txheej txheem, yog li tsim ib tug loj tus naj npawb ntawm zoo hais. Yog li ntawd, nws yog ib qho tsim nyog los tswj cov evaporation siv thaum lub sij hawm evaporation crystallization txheej txheem kom lub supersaturation ntawm cov siv lead ua yog ib txwm nyob rau hauv lub crystal metastable cheeb tsam, thiaj li yuav xyuas kom meej tias cov tsim evaporation crystallization khoom yuav tsim tau cov khoom uas ua tau raws li cov kev cai. tsim txoj haujlwm.
Qhov ntev ntawm cov siv lead ua nyob rau hauv thaj chaw loj hlob, qhov ntev ntawm cov siv lead ua loj hlob, thiab qhov loj ntawm cov siv lead ua loj. Kev tsim cov pob zeb loj loj yuav tsum muaj lub sijhawm loj hlob txaus. Raws li qhov tseeb crystallization kinetics cov ntaub ntawv, peb yuav tsim ib tug tsim nyog DTB crystallizer raws li cov siv lead ua loj hlob tus nqi thiab cov particle loj yuav tsum tau nyob rau hauv lub tsim txoj hauj lwm.
Raws li tus thawj DTB crystallizer, Kang Jinghui tau ua ntau yam kev txhim kho rau cov crystallizer kom nws ntau dua nyob rau hauv txoj kab nrog cov khoom siv tiag tiag.
