Iyini uhlelo lokubuyisa i-NMP ekukhiqizweni kwebhethri le-lithium?

Minaisingeniso

Ekukhiqizweni kwebhethri le-lithium, i-NMP isetshenziswa kabanzi ekumbozweni kwe-electrode. Ngesikhathi sokomisa, kukhiqizwa inqwaba yegesi yokukhipha equkethe i-NMP. Ngaphandle kokululama okufanele, abakhiqizi bangase babhekane nokulahlekelwa yi-solvent, ukusetshenziswa kwamandla aphezulu, kanye nengcindezi yokuhambisana ne-VOC.

Ngenxa yalesi sizathu, izinhlelo zokubuyisa i-NMP sezibe yimishini ebalulekile ezitshalweni zebhethri zesimanje.

Iyini uhlelo lokutakula lwe-NMP?

Uhlelo lokutakula i-NMP lubamba umusi we-solvent kusuka kugesi yokukhipha ugesi bese luwuguqula ube uketshezi olungasetshenziswa kabusha ngokubuyisa ukushisa, ukujiya, kanye nokuhlukaniswa kwegesi noketshezi.

Inhloso yayo eyinhloko ukunciphisa ukulahleka kwe-solvent, izindleko zamandla eziphansi, kanye nokusekela ukukhiqizwa okuhlanzekile.

Kungani kubalulekile?

Izitshalo zebhethri zidinga ukulawula izinkinga ezine ngesikhathi esisodwa: ukusetshenziswa kwe-solvent, ukukhishwa kwe-VOC, isidingo samandla okomisa, kanye nokukhiqizwa okuzinzile okukhulu.

Ezinye izinhlelo ezivamile zingahlangabezana nezidingo eziyisisekelo zokubuyisa, kodwa ukusebenza kahle kwazo kokubuyisa ukushisa kuvame ukuba cishe amaphesenti angama-60-75 ngaphansi kwemiklamo evamile. Kumaphrojekthi anezidingo zokusebenza kahle kakhulu nokuzinza, izixazululo zokubuyisa ezithuthukisiwe kakhulu noma ezihlanganisiwe zivame ukucatshangelwa.

Uhlelo lusebenza kanjani?

Ukubuyiselwa kokushisa:

• Umoya wokukhipha umoya ushintshana ngokushisa nomoya obuyayo ukuze kuncishiswe ukusetshenziswa kwamandla. Emiklamo evamile, ukusebenza kuncike esakhiweni sesistimu kanye nezimo zokusebenza, futhi ukusebenza kahle kungahluka phakathi kwamaphrojekthi.

Ukufinyela:

• Ngemva kokubuyiselwa kokushisa, umusi we-NMP upholiswa ube uketshezi. Uma kuqhathaniswa nezakhiwo zokupholisa ezilula, ukuminyana kwezigaba eziningi kuvame ukunikeza ukusebenza okuzinzile kokubuyiselwa ngaphansi kokukhiqizwa okuqhubekayo.

Ukuhlukaniswa kwegesi noketshezi:

• Ukuhlukaniswa kwegesi noketshezi kusetshenziselwa ukunciphisa ukungena koketshezi nokuthuthukisa ikhwalithi yokutakula. Izinhlelo eziyisisekelo zingasebenzisa izakhiwo ezilula zokulahla, okungaholela ezimweni zomoya obuyayo ezingazinzile.

Ukwelashwa kwe-VOC:

• Igesi yomsila iphathwa ukuze ihlangabezane nezindinganiso zemvelo. Kuye ngezidingo zephrojekthi, izinhlelo ze-adsorption rotor noma ze-absorption tower zivame ukuhlanganiswa enkambisweni yokutakula.

Izimo zohlelo lokusebenza

Izinhlelo zokubuyisa i-NMP zisetshenziswa kabanzi emigqeni yamabhethri e-EV, ezitshalweni zamabhethri okugcina amandla, kanye neminye imisebenzi yokumboza enezidingo eziqinile zemvelo kanye nokulawula izindleko.

Zibaluleke kakhulu emigqeni yokumboza ephakathi nendawo nenkulu edinga ukubuyiselwa kwe-solvent okuzinzile kanye nezindleko zokusebenza ezilawulwayo.

Abakhiqizi bamabhethri banamuhla banaka kakhulu izixazululo zokubuyisa ezihlanganisiwe kunokwelashwa okuyisisekelo kokukhipha ugesi kuphela.

Isibonelo, uhlelo lokutakula lwe-NMP lukaPengjin luhlanganisa ukubuyisa ukushisa, ukuminyana kwezigaba eziningi, kanye nokwelashwa kwegesi yomsila ekwakhiweni okuhlangene. Uhlelo lwayo lwe-cathode lusebenzisa ukusebenza kahle kokushintshana komoya nokushisa ngamaphesenti angama-90-95 kuze kufike kumaphesenti angama-85. Esixazululweni salo esisekelwe ku-rotor, ukukhishwa komoya kungalawulwa ku-5-50 mg/Nm³, ngedatha yelabhorethri ephansi njenge-1 mg/Nm³, kuyilapho isisombululo salo esisekelwe kumbhoshongo singafinyelela ku-15-50 mg/Nm³ ngaphansi kokusebenza okuzinzile.

Uhlelo lokutakula i-NMP aluyona nje idivayisi yemvelo, kodwa futhi luyithuluzi eliwusizo lokunciphisa ukulahleka kwe-solvent kanye nezindleko zokusebenza.

Izinhlelo eziyisisekelo zingafanelana namaphrojekthi amancane, kuyilapho izixazululo ezihlanganisiwe zivame ukufaneleka kakhulu emigqeni emikhulu yebhethri le-lithium enezidingo eziphakeme zokonga amandla, ukuzinza kokutakula, kanye nokulawula ukukhishwa komoya.
