Daim Ntawv Thov ntawm Lub Tshuab Distillation Luv Luv Wiped Film

I. Kev Taw Qhia
Kev siv tshuab sib cais yog ib qho ntawm peb lub tshuab tseem ceeb ntawm kev tsim tshuaj lom neeg. Cov txheej txheem sib cais muaj kev cuam tshuam loj heev rau qhov zoo ntawm cov khoom, kev ua haujlwm zoo, kev siv thiab txiaj ntsig. Lub TFE Mechanically-agitated Short Path Distillation Machine yog ib lub cuab yeej siv los ua kev sib cais los ntawm kev hloov pauv ntawm cov khoom siv. Lub cuab yeej no muaj cov coefficient hloov pauv cua sov siab, qhov kub thiab txias qis, lub sijhawm nyob luv luv ntawm cov khoom siv, kev ua haujlwm thermal siab thiab kev siv zog evaporation siab. Nws yog siv dav hauv kev lag luam ntawm petrochemicals, tshuaj zoo, tshuaj ua liaj ua teb, khoom noj, tshuaj thiab biochemical engineering, los ua cov txheej txheem ntawm kev evaporation, concentration, tshem tawm cov kuab tshuaj, purification, pa stripping, degassing, deodorization, thiab lwm yam.

Lub Tshuab Distillation Luv Luv yog lub tshuab evaporator tshiab thiab ua haujlwm tau zoo uas tuaj yeem ua rau cov zaj duab xis poob evaporation hauv qab qhov chaw nqus tsev, uas cov zaj duab xis raug yuam los ntawm lub tshuab thov zaj duab xis tig thiab muaj qhov ceev ceev, kev hloov pauv cua sov siab thiab lub sijhawm nyob luv luv (kwv yees li 5-15 vib nas this). Nws kuj muaj cov coefficient hloov pauv cua sov siab, lub zog evaporation siab, lub sijhawm ntws luv luv thiab kev ua haujlwm yooj yim, uas yog qhov tshwj xeeb tshaj yog rau kev sib sau ua ke los ntawm kev evaporation, degassing, tshem tawm cov kuab tshuaj, distillation thiab purification ntawm cov ntaub ntawv rhiab heev cua sov, cov ntaub ntawv viscosity siab thiab cov ntaub ntawv yooj yim siv lead ua thiab cov khoom muaj cov khoom me me. Nws muaj ib lossis ntau lub tog raj kheej nrog lub tsho rau cua sov thiab lub tshuab thov zaj duab xis tig hauv lub tog raj kheej. Lub tshuab thov zaj duab xis txuas ntxiv khawb cov khoom pub rau hauv cov zaj duab xis kua sib xws ntawm qhov chaw cua sov thiab thawb lawv mus rau hauv qab, thaum lub sijhawm ntawd cov khoom uas muaj cov ntsiab lus kub qis evaporation thiab lawv cov seem raug tso tawm ntawm hauv qab ntawm lub tshuab evaporator.

II. Cov yam ntxwv ntawm kev ua tau zoo
•Qhov siab nqus tsev qis:
Thaum cov pa roj uas tau ua pa ntawm cov khoom siv hloov mus los ntawm qhov chaw cua sov mus rau lub condenser sab nraud, muaj qee qhov siab sib txawv. Hauv lub evaporator ib txwm muaj, qhov siab poob (Δp) feem ntau yog siab dua, qee zaum mus rau qib tsis lees txais. Hauv kev sib piv, Lub Tshuab Distillation Luv muaj qhov chaw roj loj dua, qhov siab uas yuav luag sib npaug rau qhov hauv lub condenser; yog li ntawd, muaj qhov siab poob me me thiab qib nqus tsev tuaj yeem yog ≤1Pa.
• Kub ua haujlwm qis:
Vim yog cov yam ntxwv saum toj no, cov txheej txheem evaporation tuaj yeem ua tau ntawm qib siab nqus tsev. Txij li thaum qib nqus tsev nce ntxiv, qhov kub ntawm cov khoom sib xws txo qis sai. Yog li ntawd, kev ua haujlwm tuaj yeem ua tau ntawm qhov kub qis dua thiab qhov thermal decomposition ntawm cov khoom yog li txo qis.
• Lub sijhawm ua kom sov luv luv:
Vim yog qhov tshwj xeeb ntawm Lub Tshuab Distillation Short Path thiab kev ua haujlwm ntawm lub tshuab thov zaj duab xis, lub sijhawm nyob ntawm cov khoom siv hauv lub evaporator luv luv; ntxiv rau, qhov kev co sai ntawm zaj duab xis hauv lub evaporator cua sov ua rau cov khoom tsis tuaj yeem nyob ntawm qhov chaw evaporator. Yog li ntawd, nws yog qhov tshwj xeeb tshaj yog rau kev ua kom cov khoom siv kub-rhiab.

• Kev ua pa ntau heev:
Qhov txo qis ntawm qhov kub ntawm cov khoom siv ua rau qhov sib txawv ntawm qhov kub ntawm cov xov xwm kub nce ntxiv; lub luag haujlwm ntawm daim ntawv thov zaj duab xis txo qhov tuab ntawm cov kua zaj duab xis hauv lub xeev turbulent thiab txo qhov thermal tsis kam. Lub caij no, cov txheej txheem tswj hwm qhov caking thiab fouling ntawm cov ntaub ntawv ntawm qhov chaw cua sov thiab nrog los ntawm kev sib pauv cua sov zoo, yog li ua rau kom muaj qhov sib piv ntawm cov cua sov hloov pauv ntawm cov evaporator.

• Kev ywj pheej ua haujlwm loj:
Vim nws cov khoom tshwj xeeb, lub tshuab scraper film evaporator yog qhov tsim nyog rau kev kho cov ntaub ntawv rhiab heev uas xav tau kev ua kom du thiab ruaj khov thiab cov ntaub ntawv viscosity siab uas nws viscosity nce ntxiv nrog rau kev nce ntawm concentration, vim nws cov txheej txheem evaporation yog du thiab ruaj khov.

Nws kuj tseem tsim nyog rau kev evaporation thiab distillation ntawm cov ntaub ntawv uas muaj cov khoom me me lossis thaum muaj crystallization, polymerization thiab fouling.

III. Cov Cheeb Tsam Siv
Lub tshuab scraper zaj duab xis evaporator tau siv dav hauv cov haujlwm pauv cua sov. Nws pab hloov pauv cua sov ntawm cov ntaub ntawv rhiab heev (lub sijhawm luv luv), thiab tuaj yeem distil cov khoom nyuaj nrog nws cov haujlwm sib txawv.
Lub tshuab scraper film evaporator tau siv rau kev sib sau ua ke los ntawm kev ua kom qhuav, tshem tawm cov kuab tshuaj, tshem tawm cov pa tawm, ua kom cov tshuaj tiv thaiv, tshem cov pa roj, tshem cov pa roj, tshem cov pa roj, tshem cov ntxhiab tsw phem (de-aeration), thiab lwm yam hauv cov hauv qab no, thiab tau ua tiav cov txiaj ntsig zoo:
