Isebenza Kanjani Uhlelo Lokuncibilikisa i-NMP Futhi Kufanele Ulusebenzise Nini?
Ngemva kokululama kwe-NMP ngokumunca, uthola isisombululo esincibilikisiwe (15–30% NMP, 70–85% amanzi). Lesi sixazululo siphansi kakhulu ekugxilweni ukuze sisetshenziswe kabusha ngqo ekumbozeni. Ukuze uthole i-NMP ehlanzekile kakhulu, udinga uhlelo lokuncibilikisa. Ukuqonda indima yalo kusiza abenzi bamabhethri ukuvala ngokuphelele iluphu ye-solvent.
H1: Iyini i-NMP Distillation System?
Uhlelo lokuhluza i-NMP luhlukanisa i-NMP emanzini ngomehluko wamaphuzu okubila (NMP: 202°C, amanzi: 100°C). Isixazululo esihluzwayo siyashiswa kukholomu yokuhluza; umhwamuko wamanzi uphuma phezulu (ugobile futhi ukhishwe), kuyilapho i-NMP egxilile (99.5%+ ubumsulwa) iqoqwa phansi. Izinhlelo ezithuthukisiwe zisebenzisa i-vacuum distillation ukuze zehlise amaphuzu okubila futhi zinciphise ukuwohloka kokushisa.
H2: Yiziphi Izimo Ezidinga Ukuhluzwa Kwe-NMP Ngempela?
- Imigqa yokumboza ehlanzekile kakhulu:Ukuhlanganiswa kwe-cathode ne-anode kudinga i-NMP ngamanzi angaphansi kuka-0.1%; ukumuncwa kukodwa akukwazi ukufeza lokhu.
- Izitshalo ezinkulu zokuvuselela eziphakathi:Iyunithi eyodwa yokucwilisa isebenzisa imigqa eminingi yokumboza, iguqula i-NMP encibilikisiwe ibe yi-solvent elungele ukusetshenziswa.
- Izikhungo zokukhipha igesi ezingavalwanga:Ukuvuselelwa okuhlanganisiwe + ukuhluzwa kuqeda ukuthengwa kwe-NMP entsha.
- Izitshalo zokusebenzisa kabusha amakhemikhali:I-NMP ithengiswa kabusha kubaphakeli - idinga ukuhluzwa ukuze ihlangabezane nezinga lezimboni.
H2: Indlela i-distillation eqhathaniswa ngayo nezinye izindlela zokuhlanza
| Indlela | Umphumela Wokuhlanzeka | Izindleko Zamandla | Okuhle Kakhulu Kwaba |
| Ukuhluzwa okulula | 99.0–99.9% | Phezulu | Ukuhlanzwa ngobuningi |
| Ukuhluzwa kwe-vacuum | 99.5–99.9% | Okuphakathi nendawo | Izinhlelo zokusebenza ezithinta ukushisa |
| Ukuhlukaniswa kwe-membrane | 90–95% | Phansi | Ukugxila ngaphambi kokugxila kuphela |
Ku-NMP yezinga lebhethri, i-vacuum distillation iyindinganiso yemboni. Ivimbela ukubola kwe-NMP (okubangela ukushintsha kombala nokungcola) ngenkathi igcina umkhiqizo ophezulu.
H2: Kungani Izinhlelo Zokuhluza ZikaGuangdong Pengjin Ziyisinqumo Esihlakaniphile
Onjiniyela be-Guangdong Pengjin Intelligent Equipment Co., Ltd. bakhiqiza amayunithi okuhlanza nge-vacuum aklanyelwe izitshalo zebhethri le-lithium. Izinzuzo ezibalulekile:
- Ukuhlanganiswa kwamandla:Isebenzisa ukushisa okulahliwe okuvela kuma-oven ambozayo ukuze ifudumale ukudla kusengaphambili – inciphisa ukusetshenziswa komusi ngo-30%.
- Ukulawula okuzenzakalelayo:Uhlelo lwe-PLC lulungisa isilinganiso se-reflux kanye nokushisa ukuze kube nobumsulwa obungaguquki obungu-99.7%.
- Umklamo wokulwa nokungcola:Ama-reboilers azihlanzayo anciphisa isikhathi sokungasebenzi.
UPengjin ulethe izinhlelo zokucwilisa ezingaphezu kuka-50 kubakhiqizi bamabhethri kulo lonke elase-Asia.
H2: Izimo Zohlelo Lokusebenza Lomhlaba Wangempela
- Isimo A – Ukuhluzwa okuphakathi kwepaki ye-5GWh:Imigqa emine yokumboza iphakela i-NMP encibilikisiwe kuyunithi eyodwa yokucwilisa i-vacuum ye-Pengjin. Ukuthengwa kwe-NMP entsha kuncishiswe ngo-95%, ukonga konyaka okungu-$2.5M.
- Isimo B – Ukufakwa kabusha ku-loop evaliwe:Ifektri eyayikade igcwaliswe i-NMP (ukwelashwa kwemfucuza okubizayo). Ngemva kokufaka i-Pengjin distillation, baphinda basebenzise ama-98% e-NMP ngaphakathi - isikhathi sokukhokha izinyanga eziyi-14.
- Isimo C - Ukuthengiswa kabusha kwe-NMP:Umkhiqizi wenkontileka ubuyisele ubumsulwa be-NMP ku-99.8% futhi uyithengisela abahlinzeki bamakhemikhali, okudala umfudlana omusha wemali engenayo.
Isiphetho
Uhlelo lokuhluza i-NMP luguqula ikhambi lokubuyisa elincibilikisiwe libe yi-solvent eyigugu, ehlanzekile kakhulu. Kubalulekile kunoma yisiphi isitshalo sebhethri esihlose ukusebenza okuvaliwe noma ikhwalithi yomkhiqizo wekhwalithi ephezulu. I-Guangdong Pengjin Intelligent Equipment inikeza izixazululo zokuhluza ezisebenza kahle futhi ezenzakalelayo ezikhulisa imbuyiselo ekutshalweni kwemali. Hlanganisa ukuhluza ukuze uqedele uchungechunge lwakho lokuvuselela i-NMP.
