Pib thaum Lub Rau Hli 2020, thiab tam sim no xaus rau xyoo 2021, tus nqi ntawm cov iav photovoltaic tau dhau los ntawm ob lub coasters, ib zaug maj mus rau saum, thiab ib zaug poob rau saum toj.
Thaum lub Kaum Ib Hlis 2020, ntau lub tuam txhab photovoltaic module koom ua ke tshaj tawm cov ntaub ntawv hu rau kev daws teeb meem rau qhov tsis txaus ntawm cov iav photovoltaic. Thaum Lub Kaum Ob Hlis 16, Ministry of Industry thiab Information Technology tau tshaj tawm" Kev Ua Haujlwm Kev Ua Haujlwm rau Kev Hloov Lub Peev Xwm hauv Cement Glass Kev Lag Luam (Cov Ntawv Kho Dua Tshiab)" rau cov lus pom, qhia meej tias cov iav photovoltaic dov tsis raug rau cov kev txwv tsis pub muaj peev xwm hloov pauv.
Tus nqi me me uas tau pib thaum lub Cuaj Hlis xyoo no yog vim qhov nce ntawm cov nqi ntawm cov khoom siv raw rau cov iav photovoltaic, xws li thermal thee, soda tshauv, thiab quartz xuab zeb.
Lub luag haujlwm tseem ceeb ntawm photovoltaic iav hauv kev lag luam photovoltaic
Txawm hais tias tus nqi ntawm cov iav photovoltaic tsuas yog 6%, nws qhov kev ua tau ncaj qha txiav txim siab qhov ua tau zoo thiab lub neej ntawm photovoltaic zog tsim. Kev tsim cov txheej txheem ntawm cov iav photovoltaic nyob ntawm seb hom ntawm cov hluav taws xob photovoltaic hauv qab. Tam sim no, feem ntau paub tab thiab siv dav siv tshuab photovoltaic cell yog crystalline silicon cell, uas muaj kev lag luam thoob ntiaj teb feem ntau tshaj 80% (lwm yam yog nyias-film cell). Yog li ntawd, cov txheej txheem ntawm cov iav photovoltaic feem ntau yog ultra-dawb dov txheej txheem. Ultra-dawb txhais tau hais tias lub iav muaj cov hlau tsis tshua muaj hlau thiab muaj lub teeb pom kev zoo. Cov qauv txhais tau tias txo qhov kev xav ntawm lub teeb thiab txhim kho qhov xa tawm ntawm lub hnub ci.
Photovoltaic iav yuav tsum tau mus dhau ntau tshaj 10 kauj ruam los ntawm thawj daim ntawv mus rau cov khoom tiav, cov kev kho mob tempering tuaj yeem ua rau muaj zog ntawm cov iav photovoltaic.
Lub teeb xa hluav taws xob + lub zog siab tuaj yeem hais tias yog tib txoj hauv kev rau cov iav photovoltaic los tuav txoj haujlwm tseem ceeb.
Cov dej ntws ntawm cov iav photovoltaic yog dej qab zib tshauv (sodium carbonate), quartz xuab zeb thiab petrochemical kev lag luam. Cov khoom siv raw yog dej qab zib tshauv thiab quartz xuab zeb, thiab cov roj yog thermal thee, natural gas thiab lwm yam. Ob leeg no suav nrog ntau dua 80% ntawm tag nrho cov nqi. Raws li qhov xwm txheej no, tus nqi ntawm cov khoom lag luam nce toj tau nce, thiab nws nyuaj rau iav kom tsis txhob nce nqi.
Yuav ua li cas txo tus nqi ntawm cov iav photovoltaic
1) Txhawb kev tsim khoom muaj peev xwm
Lub iav photovoltaic nws tus kheej muaj qib siab ntawm kev tsim qauv, tab sis tus nqi ntawm cov khoom lag luam los ntawm cov tuam txhab sib txawv yog qhov zoo ib yam.
Yog li los ntawm qhov kev xav ntawm qhov qhib, nthuav cov peev txheej ntau lawm yog txoj hauv kev huab tais rau cov neeg ua si los txeeb lub khw. Xyoo 2020, cov khoom tsim tawm ntawm ultra-clear dov iav yog 7.5 lab tons, ib xyoo-rau-xyoo nce ntawm 22%. Nyob rau hauv ob peb xyoos tom ntej no, ntau lub koom haum kwv yees hais tias raws li cov downstream photovoltaic kev lag luam yog kev txhim kho, thiab hla ciam teb vaj ntxwv (xws li Kibing Group thiab Fuyao iav) txuas ntxiv mus rau hauv, lub peev xwm ntawm photovoltaic iav yuav tsum tau nthuav mus ntxiv.
2) Kev tswj tus nqi
Feem ntau hais lus, qhov loj dua qhov cub hluav taws xob ntsuas, qhov kev siv hluav taws xob tsawg dua ib tuj ntawm cov ntaub ntawv thiab roj, thiab qhov ua tau zoo dua. Feem ntau, ob leeg muaj kwv yees li kev sib raug zoo. Nyob rau tib lub sijhawm, raws li kev pabcuam lub neej ntawm lub cub tawg los tsim cov iav photovoltaic nce, cov ntaub ntawv refractory nyob rau hauv lub cub tawg yuav maj mam poob, thiab cov cua sov poob yuav nce, uas yuav txo tau lub zog efficiency ntawm lub kiln. Chav tsev nqi ntawm 1000 tons / hnub ntau lawm kab yog 10% -20% qis dua li ntawm 650 tons / hnub.
