DMF Solvent Recovery Plant
Tom qab DMF hnyav los ntawm cov txheej txheem ntau lawm yog preheated, nws nkag mus rau hauv lub cev qhuav dej. Lub dehydrating kem yog muab cov cua sov los ntawm cov chav nyob rau sab saum toj ntawm lub rectification kem. Lub DMF nyob rau hauv kem tank yog concentrated thiab pumped mus rau hauv lub evaporation tank los ntawm lub tso tawm twj tso kua mis. Tom qab cov khib nyiab pov tseg hauv lub evaporation tank yog rhuab los ntawm lub tshuab cua sov, lub vapor theem nkag mus rau hauv lub rectification kem rau rectification, thiab ib feem ntawm cov dej yog zoo tu qab tso thiab rov qab mus rau lub evaporation tank nrog DMF rau re-evaporation. DMF yog muab rho tawm los ntawm kab distillation thiab ua tiav hauv kab deacidification. Lub DMF uas ua los ntawm sab kab ntawm kab deacidification yog txias thiab pub rau hauv DMF cov khoom tiav tank.

DMF Pov Tseg Gas Recovery Plant
Nyob rau hauv lub teeb ntawm qhuav & ntub cov kab ntau lawm ntawm cov hluavtaws tawv cov tuam txhab tso tawm DMF tso pa roj, DMF pov tseg cov roj rov qab cog tuaj yeem ua kom cov pa tawm mus txog qhov yuav tsum tau muaj kev tiv thaiv ib puag ncig, thiab rov ua dua cov khoom siv DMF, siv cov khoom ua haujlwm siab ua DMF rov qab. efficiency siab dua. DMF rov qab tuaj yeem ncav cuag 95%.

DMAC Solvent Recovery Plant
Qhov no DMAC rov qab system siv tsib-theem nqus lub cev qhuav dej thiab ib-theem siab lub tshuab nqus tsev rectification kom cais DMAC los ntawm dej, thiab ua ke nrog lub tshuab nqus tsev deacidification kem kom tau txais DMAC cov khoom uas zoo heev indexes. Ua ke nrog evaporation filtration thiab residual kua evaporation system, cov impurities sib xyaw hauv DMAC cov kua khib nyiab tuaj yeem tsim cov khoom seem, txhim kho tus nqi rov qab thiab txo cov pa phem.

DMA kho cog
Thaum lub sij hawm DMF rectifying thiab rov qab txheej txheem, vim qhov kub thiab txias thiab Hydrolysis, qhov chaw ntawm DMF yuav disintergrated rau FA thiab DMA. DMA yuav ua rau muaj ntxhiab tsw phem, thiab ua rau muaj kev cuam tshuam loj rau kev ua haujlwm ib puag ncig thiab kev lag luam. Ua raws li lub tswv yim ntawm kev tiv thaiv ib puag ncig, DMA pov tseg yuav tsum tau muab pov tseg, thiab tso tawm yam tsis muaj kuab paug.

Toluene Recovery Plant
Lub toluene rov qab cog nyob rau hauv lub teeb ntawm lub super fiber cog extract seem, innovate cov nyhuv evaporation rau ob-effect evaporation txheej txheem, kom txo tau lub zog noj los ntawm 40%, ua ke nrog ntog zaj duab xis evaporation thiab cov residue ua tas mus li kev lag luam, txo cov polyethylene. nyob rau hauv cov seem toluene, txhim kho tus nqi rov qab ntawm toluene.

Residue Tshuab ziab khaub ncaws
Lub tshuab ziab khaub ncaws residue pioneered txoj kev loj hlob thiab kev txhawb nqa tuaj yeem ua rau cov khoom pov tseg uas tsim los ntawm DMF rov qab ntaus ntawv kom qhuav, thiab tsim cov slag. Txhawm rau txhim kho tus nqi rov qab los ntawm DMF, txo cov pa phem ntawm ib puag ncig, txo kev siv zog ntawm cov neeg ua haujlwm, thiab. Lub tshuab ziab khaub ncaws tau nyob hauv ntau lub lag luam kom tau txais txiaj ntsig zoo.

Dry Solvent Recovery Plant
Qhuav cov kab ntau lawm emissions tshwj tsis yog DMF kuj muaj cov ntxhiab tsw, ketones, lipids hnyav, nqus dej ntshiab ntawm cov kuab tshuaj ua haujlwm tsis zoo, lossis txawm tias tsis muaj txiaj ntsig. Lub Tuam Txhab tau tsim cov txheej txheem tshiab qhuav qhuav, hloov pauv los ntawm kev qhia txog cov kua ionic raws li cov khoom nqus, tuaj yeem rov ua dua tshiab hauv cov roj av ntawm cov kuab tshuaj, thiab muaj txiaj ntsig zoo ntawm kev lag luam thiab kev tiv thaiv ib puag ncig.

DCS Tswj System
DMF rov qab txheej txheem yog cov txheej txheem tshuaj distillation ib txwm, uas muaj ntau yam kev sib raug zoo ntawm cov txheej txheem tsis ua haujlwm thiab qhov yuav tsum tau muaj rau cov ntsuas kev rov qab los. Los ntawm cov xwm txheej tam sim no, cov cuab yeej siv tau yooj yim ua kom tiav lub sijhawm thiab kev saib xyuas zoo ntawm cov txheej txheem, yog li kev tswj xyuas feem ntau tsis ruaj khov thiab muaj pes tsawg leeg tshaj tus qauv, uas cuam tshuam rau kev tsim khoom ntawm cov lag luam. Vim li no, peb lub tuam txhab thiab Beijing University of Chemical Technology tau sib koom ua ke tsim DCS tswj qhov system ntawm DMF rov ua haujlwm engineering computer.
