Isebenza njani inkqubo ye-NMP Distillation kwaye kufuneka uyisebenzise nini?
Emva kokubuyiselwa kwe-NMP ngokufunxa, ufumana isisombululo esinyibilikisiweyo (15–30% NMP, 70–85% wamanzi). Esi sisombululo siphantsi kakhulu ekuxinaniseni ukuba singasetyenziselwa kwakhona ngqo ekugqumeni. Ukuze ufumane i-NMP ene-anhydrous ecocekileyo kakhulu, udinga inkqubo yokunyibilikisa. Ukuqonda indima yayo kunceda abenzi bebhetri bavale ngokupheleleyo iluphu ye-solvent.
H1: Yintoni iNkqubo yokuCoca i-NMP?
Inkqubo yokunyibilikisa i-NMP yahlula i-NMP emanzini ngomahluko wamanqaku okubila (i-NMP: 202°C, amanzi: 100°C). Isisombululo esinyibilikisileyo sitshiswa kwikholamu yokunyibilikisa; umphunga wamanzi uphuma phezulu (ujiyile kwaye ukhutshwe), ngelixa i-NMP exineneyo (99.5%+ ubumsulwa) iqokelelwa ezantsi. Iinkqubo eziphambili zisebenzisa i-vacuum distillation ukunciphisa amanqaku okubila nokunciphisa ukubola kobushushu.
H2: Ziziphi iimeko ezifuna i-NMP Distillation ngokupheleleyo?
- Imigca yokugquma ecocekileyo kakhulu:Ukwambathisa i-cathode kunye ne-anode kufuna i-NMP ngamanzi angaphantsi kwe-0.1%; ukufunxwa kukodwa akunakukwenza oku.
- Izityalo ezinkulu zokubuyisela izinto ezisemgangathweni:Iyunithi enye yokunyibilikisa i-distillation isebenza ngemigca emininzi yokugquma, iguqula i-NMP enyibilikisiweyo ibe sisinyibilikisi esilungele ukusetyenziswa.
- Izixhobo zokukhupha umoya ezingenalo uthuli oluvaliweyo:Ukubuyiswa okudibeneyo kunye nokucoca kuphelisa ukuthengwa kwe-NMP entsha.
- Izityalo zokusebenzisa iikhemikhali kwakhona:I-NMP ithengiswa kwakhona kubaboneleli – ifuna ukuhluzwa ukuze ifikelele kwinqanaba lemizi-mveliso.
H2: Indlela i-Distillation ethelekiswa ngayo nezinye iindlela zokuCoca
| Indlela | Isiphumo soBumsulwa | Iindleko Zamandla | Eyona ilungileyo |
| Ukuhluzwa okulula | 99.0–99.9% | Phezulu | Ukucoca ngobuninzi |
| Ukuhluzwa nge-vacuum | 99.5–99.9% | Phakathi | Izicelo ezichaphazela ubushushu |
| Ukwahlulwa kwe-membrane | 90–95% | Iphantsi | Ngaphambi kokugxila kuphela |
Kwi-NMP yomgangatho webhetri, i-vacuum distillation yeyona ndlela isemgangathweni yoshishino. Ithintela ukubola kwe-NMP (okubangela ukutshintsha kombala kunye nokungcola) ngelixa igcina amandla aphezulu.
H2: Kutheni iiNkqubo zokuCoca iGuangdong Pengjin ziLukhetho oluLungileyo
Iinjineli zeGuangdong Pengjin Intelligent Equipment Co., Ltd. zilungiselela izityalo zebhetri ye-lithium. Iingenelo eziphambili:
- Ukuhlanganiswa kwamandla:Isebenzisa ubushushu obungasasebenziyo obuvela kwii-oven zokugquma ukuze ifudumale ukutya kwangaphambili – inciphisa ukusetyenziswa komphunga ngama-30%.
- Ulawulo oluzenzekelayo:Inkqubo ye-PLC ilungisa umlinganiselo we-reflux kunye nobushushu ukuze kubekho ubunyulu obuhlala buyi-99.7%.
- Uyilo oluchasene nokungcolisa:Ii-reboilers ezizihlambululayo zinciphisa ixesha lokungasebenzi.
UPengjin unikezele ngeenkqubo zokunyibilikisa iibhetri ezingaphezu kwama-50 kubavelisi beebhetri kulo lonke elaseAsia.
H2: Iimeko zeSicelo seHlabathi lokwenyani
- Imeko A – Ukucoca okuphakathi kwepaki ye-5GWh:Imigca emine yokugquma inika i-NMP enyibilikisiweyo kwiyunithi enye ye-Pengjin vacuum distillation. Ukuthengwa kwe-NMP entsha kuncitshiswe ngama-95%, ukonga konyaka yi-$2.5M.
- Imeko B - Ukulungiswa kwakhona kwi-closed loop:Umzi-mveliso owawusele ugcwaliswe yi-NMP (unyango lwenkunkuma olubizayo). Emva kokongeza i-Pengjin distillation, bayayiphinda bayisebenzise i-98% ye-NMP ngaphakathi - ixesha lokuhlawula iinyanga ezili-14.
- Imeko C – Ukuthengiswa kwakhona kwe-NMP:Umenzi wekontrakthi yokuvelisa i-distills ubuyisele i-NMP kwi-99.8% yobumsulwa aze ayithengisele ababoneleli beekhemikhali, nto leyo edala umjelo omtsha wengeniso.
Isiphelo
Inkqubo yokunyibilikisa i-NMP iguqula isisombululo sokubuyisela esinyibilikisiweyo sibe sisinyibilikisi esixabisekileyo nesicocekileyo kakhulu. Sibalulekile kuyo nayiphi na indawo yebhetri ejolise ekusebenzeni okuvaliweyo okanye umgangatho wemveliso ophezulu. I-Guangdong Pengjin Intelligent Equipment inikezela ngezisombululo zokunyibilikisa ezisebenza ngombane nezizenzekelayo ezisebenzisa amandla kakuhle ezinika imbuyekezo enkulu kutyalo-mali. Hlanganisa ukunyibilikisa ukuze ugqibezele uthotho lwakho lokurisayikilisha i-NMP.
