I-DMF Solvent Recovery Plant
Ngemuva kokuthi i-solvent ye-DMF evela kwinqubo yokukhiqiza ishisa ngaphambili, ingena kukholomu yokuqeda amanzi. Ikholomu yokuqeda amanzi emzimbeni inikezwa umthombo wokushisa yisitimu esingaphezulu kwekholomu yokulungisa. I-DMF ethangini lekholomu igxilisiwe futhi iphonswa ethangini lomhwamuko ngepompo yokukhipha. Ngemva kokuba isincibilikisi semfucuza ethangini lokuhwamuka sishisiswe yi-heater yokuphakelayo, isigaba somhwamuko singena kukholomu yokulungisa ukuze kulungiswe, futhi ingxenye yamanzi iyabuyiswa futhi ibuyiselwe ethangini lokuhwamuka nge-DMF ukuze iphinde ihwamuke. I-DMF ikhishwa kukholomu ye-distillation futhi icutshungulwe kukholamu ye-deacidification. I-DMF ekhiqizwa emugqeni oseceleni wekholomu ye-deacidification iyapholiswa futhi ifakwe ethangini lomkhiqizo eliqediwe le-DMF.

I-DMF Waste Gas Recovery Plant
Ekukhanyeni kwemigqa yokukhiqiza eyomile nemanzi yamabhizinisi esikhumba okwenziwa akhipha igesi yokukhipha i-DMF, imboni yokukhipha imfucuza ye-DMF ingenza ukuthi igesi ifinyelele izidingo zokuvikela imvelo, futhi isebenzise kabusha izingxenye ze-DMF, kusetshenziswa izigcwalisi ezisebenza kahle zenza i-DMF ilulame. ukusebenza kahle kuphakeme. Ukutholwa kwe-DMF kungafinyelela ngaphezulu kwama-95%.

I-DMAC Solvent Recovery Plant
Lolu hlelo lokutakula lwe-DMAC lusebenzisa ukuphelelwa amanzi kwe-vacuum okuyizigaba ezinhlanu kanye nokulungiswa kwe-vacuum okuphezulu kwesigaba esisodwa ukuze kuhlukanise i-DMAC emanzini, futhi kuhlanganiswe nekholomu ye-vacuum deacidification ukuze kutholwe imikhiqizo ye-DMAC enezinkomba ezinhle kakhulu. Kuhlanganiswe ne-evaporation filtration kanye ne-residual liquid evaporation system, ukungcola okuxutshwe ku-DMAC waste liquid kungakha izinsalela eziqinile, kuthuthukise izinga lokubuyisela futhi kunciphise ukungcola.

I-DMA Treatment Plant
Phakathi nenqubo yokulungisa nokubuyisela i-DMF, ngenxa yokushisa okuphezulu kanye ne-Hydrolysis, izingxenye ze-DMF zizohlukaniswa zibe yi-FA ne-DMA. I-DMA izodala ukungcoliswa kwephunga, futhi ilethe umthelela omkhulu endaweni yokusebenza kanye nebhizinisi. Ukulandela umqondo wokuvikelwa kwemvelo, udoti we-DMA kufanele ushiswe, futhi ukhishwe ngaphandle kokungcoliswa.

I-Toluene Recovery Plant
Isitshalo sokubuyisela i-toluene ekukhanyeni kwesigaba esikhipha isitshalo se-super fiber, sisungula ukuhwamuka komphumela owodwa wenqubo yokuhwamuka okuphindwe kabili, ukunciphisa ukusetshenziswa kwamandla ngo-40%, kuhlanganiswe nokuhwamuka kwefilimu okuwayo kanye nokusebenza okuqhubekayo kokusalela, ukunciphisa i-polyethylene. ku-toluene esele, yenza ngcono izinga lokutholwa kwe-toluene.

I-Residue Dryer
Umshini wokomisa izinsalela uphayona ukuthuthukiswa nokukhuthazwa kungenza insalela yemfucuza ekhiqizwe idivayisi yokutakula i-DMF yome ngokuphelele, futhi yakhe ukwakheka kwe-slag. Ukwenza ngcono izinga lokutakula kwe-DMF, nciphisa ukungcoliswa kwemvelo, kuncishiswe umfutho wabasebenzi, futhi. Umshini wokomisa ube sezinkampanini eziningi ukuze uthole imiphumela emihle.

I-Dry Solvent Recovery Plant
Ukukhishwa komugqa wokukhiqiza wenqubo eyomile ngaphandle kwe-DMF futhi iqukethe iphunga elimnandi, ama-ketones, i-lipids solvent, ukumuncwa kwamanzi ahlanzekile kulokho kusebenza kahle kwezinyibilikisi akubi, noma akukho mphumela. Inkampani ithuthukise inqubo entsha yokubuyisela i-solvent eyomile, eyashintshwa ngokwethulwa koketshezi lwe-ayoni njengesimunyisi, ingagaywa kabusha kugesi yomsila wezinto ezincibilikayo, futhi inenzuzo enkulu kwezomnotho kanye nenzuzo yokuvikelwa kwemvelo.

I-DCS Control System
Inqubo yokutakula i-DMF iyinqubo evamile yokukhishwa kwamakhemikhali amakhemikhali, ebonakala ngezinga elikhulu lokuhlobana phakathi kwemingcele yenqubo kanye nemfuneko ephezulu yezinkomba zokubuyisela. Kusukela esimweni samanje, isistimu yensimbi evamile inzima ukufeza ukuqapha kwesikhathi sangempela nokusebenza ngempumelelo kwenqubo, ngakho-ke ukulawula kuvame ukungazinzi futhi ukwakheka kudlula izinga, okuthinta ukusebenza kahle kokukhiqiza kwamabhizinisi. Ngalesi sizathu, inkampani yethu kanye ne-Beijing University of Chemical Technology ngokuhlanganyela bathuthukise uhlelo lokulawula lwe-DCS lwekhompyutha yobunjiniyela egaywa kabusha ye-DMF.
