Sisitemu yo kugarura NMP mu gukora bateri za lithium ni iki?

JyeIntangiriro

Mu gukora batiri ya lithium, NMP ikoreshwa cyane mu gusiga electrode. Mu gihe cyo kumisha, hakorwa ingano nini y'imyuka isohora umwotsi irimo NMP. Iyo hatabayeho gukira neza, abakora bashobora guhura n'ikibazo cyo gutakaza solvent, gukoresha ingufu nyinshi, ndetse no kubahiriza umuvuduko wa VOC.

Kubera iyo mpamvu, sisitemu zo kugarura NMP zabaye ibikoresho by'ingenzi mu nganda zigezweho za bateri.

Sisitemu yo kugarura NMP ni iki?

Sisitemu yo kugarura NMP ifata umwuka uva mu mwuka usohoka utwikiriye hanyuma ikawuhinduramo amazi ashobora kongera gukoreshwa binyuze mu kugarura ubushyuhe, gushonga, no gutandukanya gazi n'amazi.

Intego yayo nyamukuru ni ukugabanya igihombo cy’ibinyabutabire, kugabanya ikiguzi cy’ingufu, no gushyigikira umusaruro utagira umwanda.

Kuki ari ingenzi?

Inganda zikora batiri zigomba kugenzura ibintu bine icyarimwe: ikoreshwa ry’ibinyabutabire, imyuka ihumanya ikirere ya VOC, ikoreshwa ry’ingufu z’umusemburo, n’umusaruro uhoraho mu buryo burambye.

Uburyo bumwe busanzwe bushobora guhaza ibikenewe by'ibanze byo kugarura ubushyuhe, ariko ubushobozi bwabwo bwo kugarura ubushyuhe akenshi buba hagati ya 60-75% ukurikije imiterere isanzwe. Ku mishinga ifite imikorere myiza kandi ihamye, ibisubizo bigezweho cyangwa bihujwe byo kugarura ubushyuhe bikunze kwitabwaho.

Sisitemu ikora ite?

Kugarura ubushyuhe:

• Umwotsi uva mu kirere uhinduranya umwuka ushyushya n'umwuka ugaruka kugira ngo ugabanye ikoreshwa ry'ingufu. Mu miterere isanzwe, imikorere iterwa n'imiterere ya sisitemu n'imiterere y'imikorere, kandi imikorere ishobora gutandukana mu mishinga itandukanye.

Ubushyuhe:

• Nyuma yo kugarura ubushyuhe, umwuka wa NMP ukonjeshwa uhinduka amazi. Ugereranyije n'imiterere yoroshye yo gukonjesha, ubushyuhe bw'ibice byinshi bukunze gutanga umusaruro uhamye wo kugarura ubushyuhe mu gihe cy'umusaruro uhoraho.

Gutandukanya gazi n'amazi:

• Gutandukanya gazi n'amazi bikoreshwa mu kugabanya uburyo amazi yinjira mu mazi no kunoza ubwiza bwo kuyagarura. Sisitemu z'ibanze zishobora gukoresha inyubako zoroshye zikuraho amazi, bishobora gutuma umwuka ugaruka mu kirere udahindagurika.

Uburyo bwo kuvura VOC:

• Imyuka yo mu mugongo itunganywa kugira ngo ihuze n'ibipimo ngenderwaho by'ibidukikije. Bitewe n'ibisabwa n'umushinga, rotor yo kuvoma cyangwa sisitemu z'iminara yo kwinjiza amazi akenshi zishyirwa mu nzira yo kugarura amazi.

Ingero z'ikoreshwa

Sisitemu zo kugarura NMP zikoreshwa cyane mu miyoboro ya bateri za EV, inganda zibika bateri z'ingufu, n'indi mishinga yo gusiga irangi ifite ibisabwa bikomeye mu kubungabunga ibidukikije no kugenzura ikiguzi.

Ni ingenzi cyane cyane ku mirongo iciriritse n'inini isaba ko ibintu bihinduka mu buryo buhamye kandi bigatwara amafaranga ahagije yo kubikoresha.

Abakora bateri zo muri iki gihe bari kwibanda cyane ku buryo bwo kugarura amazi mu buryo buhuriweho aho kwita ku buryo bworoshye bwo kuyakoresha mu gutunganya umwotsi uva mu kirere.

Urugero, sisitemu ya Pengjin yo kugarura ubushyuhe ihuza uburyo bwo kugarura ubushyuhe, uburyo bwo guhumeka mu byiciro byinshi, no gutunganya imyuka iri inyuma mu buryo bumwe. Sisitemu yayo ya cathode ikoresha 90-95% by'ubushobozi bwo gusubiza umwuka no guhanahana ubushyuhe kugeza kuri 85%. Mu gisubizo cyayo gishingiye kuri rotor, imyuka ihumanya ishobora kugenzurwa kugeza kuri 5-50 mg/Nm³, amakuru yo muri laboratwari akaba ari make nka 1 mg/Nm³, mu gihe igisubizo cyayo gishingiye ku munara gishobora kugera kuri 15-50 mg/Nm³ mu gihe ikora neza.

Sisitemu yo kugarura NMP si igikoresho gikoreshwa mu kubungabunga ibidukikije gusa, ahubwo ni n'igikoresho gifatika cyo kugabanya igihombo cya solvent n'ikiguzi cyo kuyikoresha.

Sisitemu z'ibanze zishobora guhuza imishinga mito, mu gihe ibisubizo bihujwe akenshi biba byiza cyane ku mirongo minini ya bateri ya lithium ifite ibisabwa byinshi byo kuzigama ingufu, kudahungabana mu mikorere, no kugenzura imyuka ihumanya.
