Cov txheej txheem ntau yam evaporator yog tsim nyog thiab zoo nkauj hauv kev tsim, ruaj khov hauv kev ua haujlwm, txuag hluav taws xob thiab qis hauv chav noj. Cov qauv tsim tshwj xeeb tuaj yeem hloov pauv thiab hloov kho los ntawm kev ua haujlwm yooj yim kom haum rau kev tsim cov khoom sib txawv. Lub dav hlau cua kub twj tso kua mis yuav rov nqus tau ib feem ntawm cov chav thib ob. Lub plhaub sab ntawm ib qho kev cuam tshuam evaporator tuaj yeem siv tag nrho cov cua sov. Tshav kub cov ntaub ntawv thiab cov kua dej maj mam. Nws muaj feem xyuam rau cov concentration ntawm cov ntaub ntawv kub-rhiab heev. Tom qab cov roj-kua sib cais nyob rau hauv qab ntawm lub evaporator, cov ntaub ntawv thiab cov kua nkag mus rau hauv lub separator rau re-sparation, uas txhim khu kev sib cais nyhuv thiab ua rau tag nrho cov khoom siv tau yooj yim dua nyob rau hauv kev khiav hauj lwm. Cov cuab yeej loj siv cov qauv hauv pem teb ntsug. Tag nrho cov cuab yeej muaj cov qauv compact, me me hauv pem teb thiab layout yooj yim thiab du.
Nws sawv cev rau txoj kev loj hlob ntawm loj ua tiav cov khoom siv evaporation. Kev pub noj tsis tu ncua thiab kev tso tawm thiab cov txheej txheem ntawm cov khoom siv thiab cov kua uas dhau los ntawm cov khoom siv ib zaug tuaj yeem ncav cuag qhov xav tau concentration. Cov cuab yeej tau nruab nrog CIP tu kav dej kom ua tiav hauv qhov chaw tu. Tag nrho cov cuab yeej siv tau yooj yim ua haujlwm. Lub condenser nrog cov qauv tshwj xeeb tuaj yeem ua haujlwm ib txwm ntawm 30 degree C lossis siab dua dej kub. Lub hwj chim tswj yog txhua yam paub los ntawm lub txee tswj. Lub tshuab tswj tsis siv neeg tuaj yeem ntsia tau raws li tus neeg siv yuav tsum tau ua, thiab cov khoom siv tuaj yeem ua haujlwm tsis tu ncua.
1. Thaum siv cov tshuaj corrosive thiab evaporating corrosive tov, cov yeeb nkab cua sov ntawm ntau yam evaporator yuav tsum tau ua los ntawm cov ntaub ntawv teev los yog lined nrog corrosion-resistant cov ntaub ntawv. Yog tias cov tshuaj tsis ntshai ntawm kev ua qias tuaj, nws kuj tuaj yeem siv ncaj qha rau cov evaporator ntawm ntau qhov cuam tshuam.
2. Lub viscosity thiab viscosity variation ntau yam ntawm kev daws yog ib qho tseem ceeb rau kev xaiv thaum lub sij hawm evaporation txheej txheem ntawm multi-effect evaporator.
3. Muaj cov tshuaj precipitated los ntawm siv lead ua. Thaum cov crystals nyob rau hauv cov kev daws yog sib cais, sab nraud cua sov evaporator los yog yuam kev evaporator yuav tsum tau siv.
4. Thermal stability ntawm kev daws. Tom qab cua sov rau lub sijhawm ntev, nws yooj yim rau evaporate thiab decompose. Thaum cov tshuaj scaling yuav tsum tau evaporated, evaporator nrog tsawg tuav thiab lub sij hawm tuav luv yuav tsum tau siv.
5. Tus nqi ntawm cov tshuaj thiab cov nqi ntawm cov tshuaj yuav tsum tau txiav txim siab. Thaum lub tshav kub hloov chaw ntau dua 10, nws raug nquahu kom tsis txhob siv lub tshuab ntxhua khaub ncaws los ua kom cov evaporator muaj txiaj ntsig ntau. Thaum tshav kub hloov chaw ntau dua 20, cov evaporator muaj ntau yam tuaj yeem siv tau.
6. Rau cov kev daws teeb meem uas yooj yim nthuav dav, txawm tias cov tshuaj twg yog evaporated, yog tias nws siv rau lub sijhawm ntev tom qab evaporation, yuav muaj plua plav ntawm cov khoom siv hluav taws xob. Vim tias cov thermal conductivity ntawm cov txheej txheem scaling me me, nws yog ib qho tsim nyog yuav tau xaiv cov evaporator ntau yam. Cov tshuaj uas yooj yim los ntxuav thiab muaj kev daws teeb meem ceev ceev yog yooj yim rau scale.
7. Nws yog ib qho yooj yim rau hlwv. Thaum cov tshuaj foaming evaporates, ntau txheej txheej txheej yuav raug tsim. Cov npuas dej uas yuav tsis tawg yooj yim nyob rau hauv tag nrho cov cais chamber, uas yog, lub chav los ntawm ntau cov nyhuv evaporator yog tawm ob zaug, uas tsis tsuas yog poob cov ntaub ntawv, tab sis kuj pollutes thiab condenses.
