Caij nplooj zeeg Film Evaporator

Falling film evaporation yog ntxiv cov kua rau hauv lub raj cua ntawm lub raj cua ntawm lub raj cua evaporator.Thiab cov kua ua kua thiab cov yeeb yaj duab sib dhos, nws tau muab faib rau cov hlab xa hluav taws xob.

Kev taw qhia

Falling film evaporation yog ntxiv cov kua mus rau hauv lub raj ntawm lub cua sov ntawm cov cua hauv tsev uas ua rau cov hluav taws xob ntog los ntawm cov thawv ntuag thiab ua yeeb yaj kiab tsim, nws tau muab faib rau hauv lub tshav kub pauv. cua ntws, nws tsim ib cov yeeb yaj duab zoo.Flow from to top mus rau hauv qab.Nrhiav lub ndlwg, nws yog rhuab thiab vaporized los ntawm lub plhaub ntais cua sov nruab nrab, thiab cov tshuab ua tiav thiab cov dej ua kua nkag mus rau kev sib cais chamber ntawm evaporator.The vapor -cov yog yoojyim sib cais, thiab cov pa nkag mus rau lub condenser rau kev siv ua haujlwm (ib qho haujlwm zoo tib yam) los yog nkag mus rau cov evaporator tom ntej.Qhov nruab nrab yog rhaub kom ua tiav cov haujlwm ntau, thiab cov ua kua dej yog rho tawm ntawm qhov chaw sib cais.

Txheej txheem khiav

Cov txheej txheem khiav muaj plaub hom: downstream (cocurrent), piv txwv, sib xyaw khiav (crossflow) thiab kev tawm tsam.

Yam ntxwv

(1) Cov kua qaub ntawm cov zaj duab xis ntawm cov cua evaporator tso rau sab saum toj ntawm cov evaporator, thiab nqis los ntawm phab ntsa ntawm lub raj hauv qhov kev txiav txim ntawm lub ntiajteb txawj nqhis, thiab yog cov kua qaub nyob hauv tus txheej txheem, hauv qab.Qhov zaj duab xis ntog evaporator tuaj yeem evaporate cov ntaub ntawv nrog ntau dua concentration thiab siab dua viscosity.

(2) Txij li thaum cov kua ntws hauv ib zaj yeeb yaj kiab hauv ib qho evaporator, tus kub hloov coefficient siab dua.

(3) Lub sijhawm nyob yog luv luv, nws tsis yog yooj yim ua rau khoom puas tsuaj, thiab nws tsim nyog rau cov khoom siv hluav taws xob.

(4) Lub hwj huam ua kua yog me, thiab yuav tsum ua kom tau sai sai raws li cov kev hloov hauv lub zog, qhov khoom nqus, noj nyiaj, concentration,

(5) Txij li thaum cov kua dej ntws mus raws nkaus nkaus xwb qhov kev txiav txim siab ntawm qhov tsis yog qhov sib txawv, qhov kub tsis tshua muaj kev sib txawv.

(6) Falling film evaporator yog tsim rau evaporation thiab concentration ntawm foaming cov ntaub ntawv.Vim cov kua kua evaporates hauv lub cua sov, nws cov vapor-kua sib cais.Ntawm qab ntawm cov nyhuv lub cev, feem ntau ntawm cov kua yog pumped tseg ib feem me me ntawm cov kua ua kua thiab tag nrho cov theem nrab nkag mus rau lub separator ntxiv dag zog rau kev sib cais, thiab cov kua rau txheej txheem tsis tsim kev cuam tshuam ntau heev, tsis txhob tsim cov npuas dej.
