I. Kev Taw Qhia
Kev sib cais thev naus laus zis yog ib qho ntawm peb txoj kev siv tshuaj lom neeg loj. Cov txheej txheem sib cais muaj kev cuam tshuam zoo rau cov khoom lag luam zoo, kev ua tau zoo, kev siv thiab txiaj ntsig. Lub TFE Mechanically-agitated Short Path Distillation Tshuab yog ib qho cuab yeej siv los ua kev sib cais los ntawm qhov tsis muaj zog ntawm cov ntaub ntawv. Cov cuab yeej no muaj cov coefficient ntawm cov cua kub hloov pauv, tsis tshua muaj evaporation kub, cov khoom siv nyob hauv lub sijhawm luv, thermal efficiency thiab siab evaporation siv. Nws yog dav siv hauv kev lag luam ntawm petrochemicals, tshuaj zoo, tshuaj lom neeg ua liaj ua teb, zaub mov, tshuaj thiab biochemical engineering, ua cov txheej txheem ntawm evaporation, concentration, hnyav tshem tawm, purification, steam stripping, degassing, deodorization, thiab lwm yam.
Txoj Kev luv luv Distillation yog ib qho tshiab thiab muaj txiaj ntsig evaporator uas tuaj yeem nqa tawm cov yeeb yaj kiab evaporation nyob rau hauv lub tshuab nqus tsev, uas cov yeeb yaj kiab raug yuam ua los ntawm cov neeg siv zaj duab xis rotating thiab muaj kev kub ceev, siab kub hloov efficiency thiab lub sij hawm nyob luv luv (txog 5-15 vib nas this). Nws kuj muaj cov coefficient ntawm cov cua kub hloov pauv, siab evaporation lub zog, lub sijhawm luv luv thiab kev ua haujlwm loj, uas yog tshwj xeeb tshaj yog haum rau cov concentration los ntawm evaporation, degassing, hnyav tshem tawm, distillation thiab purification ntawm cov ntaub ntawv kub-rhiab, cov ntaub ntawv siab viscosity thiab yooj yim. siv lead ua thiab particle-muaj cov ntaub ntawv. Nws muaj ib los yog ntau lub tog raj kheej nrog lub tsho rau cua sov thiab ib zaj duab xis applicator rotating nyob rau hauv lub tog raj kheej. Tus neeg siv zaj duab xis txuas ntxiv txhuam cov khoom noj rau hauv cov yeeb yaj kiab ua kua ntawm cov cua sov thiab thawb lawv mus rau hauv qab, thaum lub sij hawm cov khoom uas tsis tshua muaj kub kub evaporate thiab lawv cov residues tawm hauv qab ntawm lub evaporator.
II. Cov yam ntxwv ua haujlwm
• Lub tshuab nqus tsev siab poob qis:
Thaum cov roj vaporized ntawm cov ntaub ntawv hloov ntawm lub cua sov mus rau sab nraud condenser, muaj qee qhov sib txawv siab. Nyob rau hauv ib tug raug evaporator, xws li ib tug siab poob (Δp) yog feem ntau kuj siab, tej zaum mus rau ib tug tsis txaus degree. Nyob rau hauv sib piv, lub Short Path Distillation Tshuab muaj ib tug loj gas qhov chaw, lub siab ntawm uas yuav luag sib npaug zos rau cov condenser; yog li ntawd, muaj qhov poob siab me me thiab lub tshuab nqus tsev kawm ntawv tuaj yeem yog ≤1Pa.
• Ua haujlwm kub qis:
Vim yog cov cuab yeej saum toj no, cov txheej txheem evaporation tuaj yeem ua tiav ntawm lub tshuab nqus tsev siab. Txij li thaum lub tshuab nqus tsev kawm ntawv nce, qhov sib thooj ntawm cov khoom siv hluav taws xob txo qis sai. Yog li ntawd, kev ua haujlwm tuaj yeem ua tiav ntawm qhov ntsuas kub qis dua thiab cov thermal decomposition ntawm cov khoom yog li txo.
• Lub sijhawm cua sov luv:
Vim yog cov qauv tshwj xeeb ntawm Txoj Kev Luv Distillation Tshuab thiab cov twj tso kua mis ntawm tus neeg siv zaj duab xis, lub sijhawm nyob ntawm cov ntaub ntawv hauv cov evaporator yog luv; Nyob rau hauv tas li ntawd, qhov ceev ceev turbulence ntawm zaj duab xis nyob rau hauv lub cua sov evaporator ua rau cov khoom nyob rau hauv lub evaporator nto. Yog li ntawd, nws yog tshwj xeeb tshaj yog haum rau evaporation ntawm tshav kub-sensitive cov ntaub ntawv.
• Siab evaporation siv:
Qhov txo qis ntawm qhov kub ntawm cov ntaub ntawv nce qhov kub ntawm qhov sib txawv ntawm cov khoom cua sov; kev ua haujlwm ntawm tus neeg siv zaj duab xis txo cov thickness ntawm cov kua zaj duab xis nyob rau hauv ib tug turbulent xeev thiab txo cov thermal kuj. Lub caij no, cov txheej txheem suppresses lub caking thiab fouling ntawm cov ntaub ntawv nyob rau hauv lub cua sov nto thiab yog nrog los ntawm zoo tshav kub pauv, yog li ua rau tag nrho cov tshav kub hloov coefficient ntawm lub evaporator.
• Kev ua haujlwm loj ua haujlwm yooj yim:
Vim nws cov khoom tshwj xeeb, cov khoom siv hluav taws xob evaporator yog tsim rau kev kho cov ntaub ntawv kub-rhiab heev uas yuav tsum tau evaporation du thiab ruaj khov thiab cov ntaub ntawv viscosity siab uas nws cov viscosity nce ntau heev nrog kev nce siab, vim nws cov txheej txheem evaporation yog du thiab ruaj khov.
Nws kuj yog tsim rau evaporation thiab distillation ntawm cov ntaub ntawv uas muaj hais los yog nyob rau hauv cov ntaub ntawv ntawm crystallization, polymerization thiab fouling.
III. Cov cheeb tsam thov
Lub scraper zaj duab xis evaporator tau siv dav hauv cov phiaj xwm kev sib hloov cua sov. Nws pab cov cua sov sib pauv ntawm cov ntaub ntawv kub-rhiab heev (lub sijhawm luv) tshwj xeeb, thiab tuaj yeem cuam tshuam cov khoom lag luam nrog nws ntau yam haujlwm.
