Tsis ntev los no, Ministry of Ecological Environment tau tshaj tawm lub xeev ib puag ncig kev tiv thaiv tus qauv "Khoom lithium-ion fais fab cia roj teeb kho cov pa phem tswj kev siv thev naus laus zis (Draft for Comment)" (tom qab no hu ua "Technical Specifications"), txhawm rau tiv thaiv cov hluav taws xob lithium-ion pov tseg. khaws cov roj teeb los ntawm kev ua qias tuaj ib puag ncig, tiv thaiv tib neeg kev noj qab haus huv. Tuam Tshoj muaj lub ntiaj teb loj tshaj plaws tshiab zog tsheb lag luam, nyob rau hauv xyoo tas los no, lub zog loj hlob sai. Lub roj teeb lithium ion tau suav tias yog ib qho ntawm lub zog hluav taws xob nyiam los ntawm lub zog tshiab tsheb vim nws qhov zoo ntawm lub zog ceev, kev ua haujlwm me me ntawm tus kheej, rov siv dua.

Nws yog ib qho tsim nyog sau cia tias vim lub neej tsis muaj roj teeb lithium-ion, cov thev naus laus zis tau hloov kho tas li, thiab cov roj teeb lithium-ion tab tom yuav nce mus rau qhov ntsuas, scrapped "me me ncov". Yog tias lub roj teeb khib nyiab pov tseg tsis raug, nws yuav ua rau muaj teeb meem xws li kev noj qab haus huv, kev nyab xeeb, kev ua qias tuaj ib puag ncig. Yog li "Technical Specification" txhais li cas rau kuv lub teb chaws txoj kev lag luam roj teeb rov qab? Dab tsi ntawm kev txhawb nqa kev siv cov khoom siv rov ua dua tshiab, thiab kev tswj cov pa phem ntawm cov roj teeb hluav taws xob pov tseg, thiab yuav txhawb nqa li cas? Txhawm rau txhim kho cov ntaub ntawv txheeb cais, xyoo no kuv lub teb chaws lub zog roj teeb yuav nkag mus rau qhov ntsuas ntawm cov nyiaj laus, raws li 70% tuaj yeem siv rau kev suav cov ntaiv, txog 60,000 tons ntawm cov roj teeb hluav taws xob yuav tsum tau muab pov tseg.

Lub zog roj teeb rov ua dua tshiab yuav tshwm sim. Qhov twg pov tseg lithium ion fais fab cia, yuav ua li cas kom huv si, ntsuab, txoj kev nyab xeeb, cov teeb meem no dhau los ua qhov kev txhawj xeeb ntawm kev lag luam. Kev taw qhia txog "Technical Specifications" tuaj yeem tso cai rau kev lag luam los txhim kho txoj kev.

"Technical Specifications" ua ntej muab lub ntsiab lus meej ntawm "khoom siv lithium ion fais fab tuag": poob tus nqi siv qub, lossis lithium-ion fais fab tuag roj teeb uas tsis ploj, tab sis muab pov tseg lossis tso tseg, tsis suav nrog lub ntsiab rov qab los ntawm cov khoom siv hluav taws xob. txee lub neej Fault detection, kho refurbished lithium-ion zog cia roj teeb. Tsis tas li ntawd, los ntawm cov yam ntxwv ntawm kev tswj kev ua pa phem, kev ua haujlwm ntawm kev tswj hwm ib puag ncig, kev tswj hwm ib puag ncig thaum muaj xwm txheej ceev, thiab lwm yam "Tam sim no, kev lag luam yuav tsum muaj kev tiv thaiv ib puag ncig, kev taw qhia txog "Technical Specifications", los ntawm kev muaj los yog muaj peev xwm ua rau muaj kuab paug. tam sim no lub hwj chim roj teeb, ntsuab lub hwj chim roj teeb ub txheej txheem, txhawb kev lag luam ntau tus qauv tsim.

"Tus kws tshawb fawb ntawm cov txheej txheem Engineering lub koom haum ntawm Suav Academy ntawm Sciences" Suav Science News ". "Ua ntej no, kuv lub teb chaws tsis tau hais tshwj xeeb tso rau pem hauv ntej kev tiv thaiv kev ua qias tuaj rau lub hwj chim roj teeb rov qab kev lag luam, tsuas yog cov kev cai dav dav. "Yang Qingyu, Tus Lwm Thawj Tuav Haujlwm ntawm Tuam Tshoj Roj Teeb Alliance, ntseeg hais tias yog ib qho tseem ceeb ntawm tag nrho cov kev lag luam kev lag luam rov ua dua tshiab," Cov Lus Qhia Tshwj Xeeb "muaj cov yam ntxwv ntawm kev lag luam nws tus kheej, thiab muab cov ncauj lus kom ntxaws thiab cov cai tshwj xeeb rau kev tswj cov pa phem ntawm kev rov ua dua qub. tuam txhab uas muag, pab nyob rau hauv lub hwj chim roj teeb ub kev lag luam mus rau ntsuab, environmentally friendly txoj kev loj hlob, txhawb kev lag luam transformation thiab upgrading.

Nyob rau hauv qhov tseeb, nyob rau hauv xyoo tas los no, domestic fais fab roj teeb recycling txoj cai tau txuas ntxiv mus hloov tshiab, nrog rau lub hwj chim roj teeb txoj kev tswj, traceability kev tswj, kev tswj platform siv, txheem tej yam kev mob, qhov hluav taws xob tsim thiab kev ua hauj lwm, thiab lwm yam, thiab tsim lub hwj chim roj teeb rov ua dua thiab siv tag nrho lub neej. cycle lub teb chaws Standard system, coj kev lag luam kev noj qab haus huv txoj kev loj hlob, txhawb lub hwj chim roj teeb kev ruaj ntseg thiab orderly recycling. Txoj cai kev taw qhia txhawb kev lag luam rov qab paub txog.

Raws li kev txheeb cais ntawm Tuam Tshoj Roj Teeb Alliance, txij li Lub Ob Hlis 2020, 130 tuam txhab lag luam hauv lub tebchaws tau tshaj tawm 11229 qhov kev pabcuam rov ua dua tshiab, thiab lub tuam txhab tsheb nruab nrab tau tshaj tawm 86 qhov chaw rov ua dua tshiab. "Txoj cai tswjfwm tau maj mam tsim, tus qauv yog maj mam txhim kho, thiab kev tsim kho ntawm tag nrho cov txheej txheem rov ua dua tshiab kuj tau ntau dua. Yang Qingyu tau hais.

Qhov sib txawv ntawm cov kev cai sib txawv ntawm cov kev xav tau sib txawv, kev txhim kho txuas ntxiv ntawm kev tswj cov pa phem ntawm cov saw fais fab, txhawb kev txhim kho ntsuab kom ruaj khov ntawm kev lag luam. Nyob rau hauv cov nqe lus ntawm kev tswj cov pa phem technology, "Technical Specifications" tau piav qhia los ntawm cov kev cai ntawm kev tswj cov pa phem, qhov kawg ntawm kev tswj cov pa phem yuav tsum tau ua. Sun Wei tau hais tias nyob rau hauv cov nqe lus ntawm txoj kev kev, muaj ob lub ntsiab ntawm kev lag luam kev siv.

Ib hom yog cov txheej txheem hluav taws-ntub ntub dej sib koom ua ke, kom cov roj teeb pov tseg tau npaj los ntawm kev kub siab smelting, ntxiv ntub dej sib cais thiab purification, ua rau cov khoom muaj feem xyuam. Lwm hom yog pyrolysis pretreatment - ntub metallurgy ua ke cov txheej txheem rov ua dua tshiab. Ntawd yog, cov organic teeb meem ntawm cov roj teeb pov tseg yog thawj zaug tshem tawm, thiab kev xaiv xaiv, cov hmoov dub uas nplua nuj nyob hauv lithium-nplua nuj cov ntsiab lus tau txais, thiab tom qab ntawd cov hmoov dub tau rov qab los ntawm cov txheej txheem ntub dej kom ntxiv cov roj teeb zoo. khoom.

"Ob txoj kev muaj qhov tshwj xeeb, txhua qhov kev cia siab 'los ntawm lub roj teeb', tom qab ntawd 'rov qab mus rau lub roj teeb'. "Sun Wei hais. Qhov tseeb, nyob rau hauv cov nqe lus ntawm lub hwj chim roj teeb rov ua lag luam, kuv lub teb chaws tau mus rau pem hauv ntej, "vim peb cov teeb meem thiab kev thov tau tshwm sim ua ntej, ntau ceev".

Cov khib nyiab lithium-ion fais fab roj teeb rov ua dua tshiab suav nrog kev sib sau, khaws cia, kev thauj mus los, thiab tso tawm, tawg, sib cais, hlau rho tawm, thiab lwm yam, cov ntu sib txawv muaj cov kev cai sib txawv rau kev tswj cov pa phem. Yang Qingyu hais rau "China Science News" hauv kev sau cia, tsom mus rau qhov teeb meem ntawm electrolyte to.

Lithium hexafluorophosphate yog qhov tseem ceeb tshaj plaws ntawm cov electrolyte, txog 43% ntawm cov electrolyte, nws yooj yim rau volatilize, tso tawm hydrogen fluoride kuab paug rau ib puag ncig. Nyob rau hauv lub dismantling sorting, smelting txuas yuav tsum xyuas kom meej kev xaiv ntawm qhov chaw ua hauj lwm, thiab kev kho mob ntawm cov dej khib nyiab khib nyiab pov tseg. "Ua kom muaj kev nyab xeeb ntsuab rov qab, ze rau ntawm cov chaw lag luam, cov khoom siv ib puag ncig, kev tiv thaiv ib puag ncig, thiab lwm yam.

"Sun Wei kuj tau hais tias qhov kev pheej hmoo ntawm cov roj teeb hluav taws xob ib puag ncig muaj kuab paug yog ib qho teeb meem kev txhawj xeeb tshaj plaws hauv kev lag luam. Ntxiv nrog rau cov hluav taws xob xau, kuj tseem muaj cov hlau hnyav hnyav ntawm tooj liab npib tsib xee, lwm yam pov tseg pov tseg thaum kho; ntxiv rau. , yog tias qhov kev kho mob tsis raug, cov hluav taws xob seem yuav ua rau muaj kev sib tsoo, tawg, thiab lwm yam. Nws tau taw qhia tias "cov txheej txheem kev kho mob yav dhau los yog lub hom phiaj ntawm lub hwj chim roj teeb rov qab tswj cov pa phem.

"Nyob rau hauv xyoo tas los no, cov tuam txhab muaj feem cuam tshuam tau pib tsim yuav ua li cas los txiav txim siab yuav ua li cas kom yooj yim dua, muaj kev nyab xeeb thiab tus phooj ywg zoo ib puag ncig thaum lub roj teeb rov qab tau zoo thaum lub roj teeb hauv pem hauv ntej kawg." Txhawm rau coj mus rau qhov xav tau ntawm cov tsheb hluav taws xob, qhov nyuaj. tseem loj heev, tab sis muaj kev sim hauv tsev thiab txawv teb chaws los tshawb nrhiav. "Sun Wei hais.

Cov kev cia siab muaj ntau yam kev tshawb nrhiav tas li, thiab kev loj hlob sai ntawm lub zog tshiab tsheb tau ua rau muaj kev loj hlob ntawm lithium-ion fais fab hlwb, thiab tseem coj tau kev lag luam dav dav rau kev rov ua dua lithium ion zog roj teeb. Muaj cov ntaub ntawv kwv yees, xyoo 2020, kuv lub teb chaws lub zog roj teeb rov ua lag luam yuav ncav cuag 10.7 billion yuan, uas yog kwv yees li 6.

4 billion yuan nyob rau hauv txoj kev tsheb ciav hlau, thiab kev lag luam rov tsim dua yog li 4.3 billion yuan. Yang Qingyu tau hais tias lub hauv paus tseem ceeb ntawm kev rov ua dua roj teeb yog txhawm rau txuas lub neej tag nrho ntawm lub roj teeb, txhim kho tus nqi ntawm kev rov tsim dua tshiab.

Ntawm lawv, lub roj teeb ntaiv yog tsim nyog rau kev saib xyuas, los ntawm lub hwj chim roj teeb unloaded los ntawm lub zog tshiab lub tsheb, raws li kev soj ntsuam kev nyab xeeb thiab kev kwv yees lub neej, nws kuj tseem siv tau rau cov tsheb uas tsis muaj hluav taws xob, hluav taws xob tsheb kauj vab, me me faib. lub zog cia. "Ntxiv rau cov thev naus laus zis, kev lag luam tam sim no muaj kev txhawj xeeb txog kev rov ua dua tshiab thiab kev lag luam." Yang Qingyu ntseeg siab, tus naj npawb ntawm cov roj teeb hluav taws xob so hauv khw tau qis dua qhov kev cia siab ntawm kev lag luam, kev rov qab los tsis txaus, tsis muaj qhov cuam tshuam loj tuaj yeem. yog cov teeb meem tshwm sim ntawm cov roj teeb rov ua lag luam.

Hauv nws qhov kev xav, qhov laj thawj yuav suav nrog cov neeg siv khoom tsis nco qab, cov khoom siv rov ua dua tsis zoo, thiab lwm yam "Thaum lub zog roj teeb muaj peev xwm attenuated rau 80%, nws ncav cuag tus qauv tsheb, tab sis lub roj teeb siab dua, thiab cov neeg siv khoom yuav ' hloov lub roj teeb tsis zoo li ob xyoos. "Yang Qingyu tau hais tias feem ntau, lub roj teeb tau so haujlwm, kev lag luam dav dav, ib sab yuav tsum tau coj cov neeg siv khoom siv roj teeb rov qab los ntawm cov kev sib txuas, ntawm qhov tod tes, kom muaj zog. kev saib xyuas.

Li Jinhui, xib fwb Li Jinhui, ib tug Tsinghua University Environmental College, nyob rau hauv tsis ntev los no foundations ntawm daim ntawv ntawm 15th Solid Waste Management and Technology International Conference, tam sim no kev tsim kho ntawm kuv lub teb chaws lub hwj chim roj teeb ub system tsis zoo tag nrho. Tam sim no, lub zog hluav taws xob rov ua dua tshiab feem ntau yog nyob ntawm kev tsim kho tsheb tsim cov tuam txhab, muaj qee yam kev pheej hmoo kev nyab xeeb, thiab kev tshaj lij ntawm cov neeg ua haujlwm tsis txaus. Tsis tas li ntawd, qhov kev pab cuam ntawm lub hwj chim roj teeb rov qab system yog nce, thiab tag nrho cov nqi rov qab yog siab, thiab cov efficiency ntawm recycling thiab siv tsis pom tseeb.

Kev koom tes ntawm cov lag luam sab saud thiab qis qis yuav tsum muaj zog, thiab kev faib cov peev txheej ntawm cov khoom siv rov ua dua tshiab yuav tsum tau ua kom zoo dua. Nyob rau hauv kev pom ntawm Sun, yav tom ntej yuav tsum tau ntxiv dag zog rau automation theem ntawm roj teeb rov qab technology thiab khoom siv. "Vim qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv ntawm cov roj teeb pob, muaj kev txhim kho loj hauv kev siv tshuab dismantling thiab lwm yam thev naus laus zis.

"Cov kws tshaj lij tau taw qhia tias nws yog qhov tsim nyog los tsim lub tuam txhab-coj roj teeb rov ua lag luam cov saw hlau, thiab tseem yuav tsum tau txhawb nqa kev taw qhia, kev txhawb nqa kev tshawb fawb, kev txhawb nqa pej xeem, thiab lwm yam Xov Xwm Tuam Tshoj Science News.
