Khoom Description
OSLO lub tshuab nqus tsev crystallizer yog lub txaj fluidized crystallizer nrog particle loj cais. Nws lub ntsiab feature yog tias cov kua supersaturated ntws ncaj nraim mus rau hauv qab ntawm crystallizer raws tus downcomer nyob rau hauv nruab nrab ntawm lub crystallizer, thiab ces tig mus rau sawv. Thaum lub sij hawm nce, cov kua supersaturated dhau los ntawm lub txaj fluidized thiab tag nrho hu rau cov khoom siv hluav taws xob tshem tawm, kom cov crystal nuclei tuaj yeem loj hlob thiab supersaturation tuaj yeem raug tshem tawm. OSLO crystallizer tuaj yeem tsim cov khoom siv lead ua nrog cov khoom loj dua.
Thaum lub sij hawm evaporation crystallization txheej txheem, 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 heev supersaturation. Kev tshem tawm ntawm supersaturation feem ntau yog nyob ntawm qhov tshwm sim ntawm nucleation ntawm cov muaju thiab cov txheej txheem loj hlob ntawm cov muaju. Yog tias muaj cov khoom siv lead ua txaus txaus thiab kev loj hlob sai hauv cov crystallizer, lub supersaturation generated 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. Lub solute yuav tsis tshem tawm cov supersaturation los ntawm cov txheej txheem nucleation, yog li ntawd ntau tus siv lead ua nuclei yuav tsis tsim.
Yog tias cov khoom siv lead ua hauv cov tshuaj tsis txaus, qhov kev loj hlob ntawm cov khoom siv lead ua tsis txaus los tshem tawm cov supersaturation los ntawm evaporation, ua rau cov tshuaj supersaturation siab dhau thiab nyob rau hauv qhov chaw tsis ruaj khov. Lub supersaturation ntawm cov tshuaj yuav tau noj los ntawm tus txheej txheem ntawm nucleation, 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 crystallization system yog ib txwm nyob rau hauv lub crystallization metastable cheeb tsam, yog li xyuas kom meej tias cov tsim evaporation crystallization khoom yuav tsim tau cov khoom uas ua tau raws li qhov yuav tsum tau ntawm tus tsim txoj hauj lwm. .
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. Peb yuav tsim OSLO crystallizer tsim nyog raws li qhov tseeb crystallization kinetics cov ntaub ntawv, raws li cov siv lead ua kev loj hlob tus nqi thiab cov particle loj yuav tsum tau nyob rau hauv lub tsim ua hauj lwm.Raws li tus thawj OSLO, ENCO tau ua ntau yam kev txhim kho rau lub crystallizer kom nws ntau. nyob rau hauv txoj kab nrog cov khoom siv tiag tiag.
Txoj kev ua haujlwm: nruam crystallization, intermittent crystallization
Crystallization txoj kev: dej txias crystallization, evaporation crystallization, khov crystallization, nqus crystallization
