DMF Solvent Recovery Plant
Pambuyo pa zosungunulira za DMF kuchokera kuzinthu zopangira zimatenthedwa, zimalowa m'kati mwa dehydrating. Dehydrating column imaperekedwa ndi gwero la kutentha ndi nthunzi pamwamba pa ndime yokonzanso. DMF mu thanki yazambiri imakhazikika ndikuponyedwa mu thanki ya evaporation ndi mpope wotulutsa. Pambuyo pa zosungunulira zinyalala mu thanki ya nthunzi zitenthedwa ndi chotenthetsera cha chakudya, gawo la nthunzi limalowa mugawo lokonzanso kuti likonzenso, ndipo gawo lina la madzi limabwezedwa ndikubwezeredwa ku thanki ya evaporation ndi DMF kuti iwukenso nthunzi. DMF imachotsedwa ku distillation column ndikukonzedwa mu gawo la deacidification. DMF yopangidwa kuchokera pamzere wam'mbali wa gawo la deacidification imakhazikika ndikudyetsedwa mu tanki yomalizidwa ya DMF.

DMF Waste Gas Recovery Plant
Poyang'ana mizere yowuma ndi yonyowa yamabizinesi opangira zikopa otulutsa mpweya wa DMF, malo obwezeretsa zinyalala a DMF amatha kupangitsa kuti utsiwo ufikire zofunikira pachitetezo cha chilengedwe, ndikubwezeretsanso zida za DMF, pogwiritsa ntchito ma filler apamwamba kwambiri kuti DMF ibwerere. Kuchita bwino kwambiri. Kuchira kwa DMF kumatha kufika pamwamba pa 95%.

DMAC Solvent Recovery Plant
Dongosolo lobwezeretsa la DMACli limagwiritsa ntchito magawo asanu a vacuum dehydration ndi gawo limodzi lowongolera vacuum kuti alekanitse DMAC ndi madzi, ndikuphatikiza ndi gawo la vacuum deacidification kuti apeze zinthu za DMAC zokhala ndi zolozera zabwino kwambiri. Kuphatikizidwa ndi kusefera kwa evaporation ndi njira yotsalira yamadzimadzi evaporation, zonyansa zosakanizidwa mumadzi amadzimadzi a DMAC zitha kupanga zotsalira zolimba, kuwongolera kuchuluka kwa kuchira ndikuchepetsa kuipitsidwa.

Malo Ochizira a DMA
Panthawi yokonza ndi kuchira kwa DMF, chifukwa cha kutentha kwambiri ndi Hydrolysis, mbali za DMF zidzasokonezedwa ku FA ndi DMA. DMA idzayambitsa kuipitsidwa kwa fungo, ndikubweretsa vuto lalikulu kwa malo ogwirira ntchito ndi bizinesi. Kutsatira lingaliro lachitetezo cha chilengedwe, zinyalala za DMA ziyenera kutenthedwa, ndikutayidwa popanda kuipitsa.

Zowumitsa Zotsalira
Choumitsira chotsaliracho chinayambitsa chitukuko ndi kukwezedwa kungapangitse zotsalira za zinyalala zopangidwa ndi chipangizo cha DMF chowuma chouma, ndi kupanga mapangidwe a slag. Kupititsa patsogolo chiwopsezo cha kuchira kwa DMF, kuchepetsa kuipitsidwa kwa chilengedwe, kuchepetsanso kuchuluka kwa ogwira ntchito. Chowumitsira chakhala m'mabizinesi angapo kuti mupeze zotsatira zabwino.

Dry Solvent Recovery Plant
Njira zowuma zotulutsa zotulutsa kupatula DMF zilinso ndi zonunkhira, ma ketoni, zosungunulira za lipids, mayamwidwe amadzi oyera pazosungunulira zotere ndizosauka, kapena zilibe kanthu. Kampaniyo idapanga njira yatsopano yobwezeretsa zosungunulira zowuma, zomwe zidasinthidwa poyambitsa madzi a ionic monga choyezera, zitha kubwezeretsedwanso mu mpweya wosungunulira mchira, ndipo ili ndi phindu lalikulu pazachuma komanso chitetezo cha chilengedwe.

DCS Control System
DMF kuchira ndondomeko ndi mmene mankhwala distillation ndondomeko, yodziwika ndi mlingo waukulu wa malumikizanidwe ndondomeko magawo ndi chofunika kwambiri zizindikiro kuchira. Kuchokera pazochitika zamakono, dongosolo lachida lachidziwitso ndilovuta kukwaniritsa nthawi yeniyeni komanso yowunikira ndondomekoyi, kotero kulamulira nthawi zambiri kumakhala kosasunthika ndipo mapangidwe ake amaposa muyezo, zomwe zimakhudza kupanga mabizinesi. Pazifukwa izi, kampani yathu ndi Beijing University of Chemical Technology mogwirizana adapanga makina owongolera a DCS a makompyuta obwezeretsanso DMF.
