He aha te pūnaha whakaora NMP i roto i te hanga pākahiko lithium?

ahauwhakataki

I roto i te hanga pākahiko lithium, he whānuitia te whakamahinga o te NMP i roto i te paninga hiko. I te wā whakamaroke, he nui ngā rahinga hau putanga kei roto he NMP ka puta. Ki te kore e tika te whakaora, ka raru pea ngā kaihanga i te ngaronga o te whakarewa, te nui ake o te whakamahinga pūngao, me te pēhanga tutuki VOC.

Nā konei, kua noho ngā pūnaha whakaora NMP hei taputapu nui i roto i ngā tipu pākahiko o ēnei rā.

He aha te pūnaha whakaora NMP?

Ka hopukina e te pūnaha whakaora NMP te kohu whakarewa mai i te hau putanga paninga, ka hurihia hei wai ka taea te whakamahi anō mā te whakaora wera, te hauhautanga, me te wehenga hau-wai.

Ko tōna whāinga matua he whakaiti i te ngaronga o te whakarewa, he whakaiti i te utu pūngao, me te tautoko i te whakaputanga kai ma.

He aha te mea nui?

E whā ngā take me whakahaere e ngā tipu pākahiko i te wā kotahi: te whakamahinga o te whakarewa, ngā tukunga VOC, te hiahia mō te pūngao whakamaroke, me te whakaputanga nui pumau.

Ka taea e ētahi pūnaha tuku iho te whakatutuki i ngā hiahia whakaora taketake, engari ko te pai o te whakaora wera he tata ki te 60–75 ōrau i raro i ngā hoahoa noa. Mō ngā kaupapa he nui ake ngā whakaritenga pai me te pumau, ka whakaarohia ngā otinga whakaora matatau ake, ngā otinga whakaora whakauru rānei.

Me pēhea te mahi a te pūnaha?

Te whakaora wera:

• Ka whakawhitihia te wera e te hau putanga ki te hau hoki hei whakaiti i te whakapaunga pūngao. I roto i ngā hoahoa tuku iho, ka whakawhirinaki te mahi ki te hanganga pūnaha me ngā āhuatanga whakahaere, ā, ka rerekē pea te whai huatanga puta noa i ngā kaupapa.

Te whakapūpūtanga:

• I muri i te whakaoranga o te wera, ka whakamataohia te mamaoa NMP hei wai. Ki te whakatauritea ki ngā hanganga whakamatao māmā ake, ko te whakapūmau maha-wāhanga te tikanga ka whakarato i te mahi whakaoranga pumau ake i raro i te whakaputanga tonu.

Te wehenga hau-wai:

• Ka whakamahia te wehenga hau-wai hei whakaiti i te urunga o te wai, hei whakapai ake hoki i te kounga o te whakaora. Tērā pea ka whakamahia e ngā pūnaha taketake ngā hanganga tango hau māmā ake, ā, ka kore e pumau te āhua o te hau whakahoki.

Te maimoatanga VOC:

• Ka tukatukahia te hau hiku kia tutuki ai ngā paerewa taiao. I runga anō i ngā whakaritenga o te kaupapa, ka whakauruhia ngā pūnaha rotor adsorption, ngā pūnaha pourewa absorption rānei ki te tukanga whakaora.

Ngā horopaki tono

E whakamahia whānuitia ana ngā pūnaha whakaora NMP i roto i ngā raina pākahiko EV, ngā tipu pākahiko rokiroki pūngao, me ētahi atu kaupapa paninga he tino kaha ngā whakaritenga taiao me te whakahaere utu.

He mea tino nui ēnei mō ngā raina paninga reo-rahi, me te rahi e hiahia ana ki te whakaora whakarewa pumau me te utu whakahaere e whakahaeretia ana.

Kei te aro nui ake ngā kaihanga pākahiko o ēnei rā ki ngā otinga whakaora whakauru, kaua ki te maimoatanga noa iho o ngā hauātanga.

Hei tauira, ka whakauruhia e te pūnaha whakaora NMP a Pengjin te whakaora wera, te hauhautanga maha-wāhanga, me te maimoatanga hau hiku ki roto i tētahi hoahoa kotahi. Ka whakamahia e tana pūnaha katote te 90–95 ōrau o te hau whakahoki me te pai o te whakawhiti wera tae atu ki te 85 ōrau. I roto i tana otinga e hangai ana ki te rotor, ka taea te whakahaere i ngā tukunga ki te 5–50 mg/Nm³, me ngā raraunga taiwhanga he iti iho i te 1 mg/Nm³, ko tana otinga e hangai ana ki te pourewa ka taea te whakatutuki i te 15–50 mg/Nm³ i raro i te mahi pumau.

Ehara i te mea he taputapu taiao noa iho te pūnaha whakaora NMP, engari he taputapu whai hua anō hoki hei whakaiti i te ngaronga o te whakarewa me te utu whakahaere.

Tērā pea ka uru ngā pūnaha taketake ki ngā kaupapa iti ake, ko ngā otinga whakauru ia he pai ake mō ngā raina pākahiko lithium nui ake me ngā whakaritenga teitei ake mō te penapena pūngao, te pumau whakaora, me te whakahaere tukunga.
