I. Muab pov tseg rau hauv cov khoom muaj nqis: Kev siv cov khoom siv ntawm Desulfurized Gypsum
Hauv kev tsim khoom ib txwm muaj, gypsum board feem ntau tso siab rau ntuj gypsum ore. Peb cov thev naus laus zis tseem ceeb tsom mus rau qhov loj - nplai siv "desulfurized gypsum" ua raw khoom.
Dab tsi yog Desulfurized Gypsum?
Marine desulfurized gypsum yog ib hom desulfurized gypsum uas tsim nyob rau hauv industrial flue gas desulfurization khoom nyob rau hauv thee - hluav taws xob fais fab nroj tsuag. Cov sulfur dioxide nyob rau hauv cov roj flue yog hloov mus rau hauv gypsum los ntawm limestone -gypsum ntub desulfurization txheej txheem. Keeb kwm, cov khoom lag luam no tau raug denigrated raws li qhov chaw -kev siv pov tseg tsis txaus ntseeg tau suav hais tias "tsuas yog pov tseg" thiab tau muab pov tseg rau hauv qhov chaw pov tseg uas lawv ua rau muaj kev txhawj xeeb txog ib puag ncig.
Peb yuav ua li cas hloov nws mus rau hauv siab - cov ntaub ntawv zoo?
Directly tsim desulfurized gypsum muaj qee qhov dej noo thiab impurities thiab tsis tuaj yeem siv ncaj qha rau hauv kev tsim khoom. Yog li ntawd, peb tau tsim ib tug nruj pretreatment txheej txheem:
Ntxuav thiab Purification: Ua ntej, peb ntxuav cov khoom nyoos kom tshem tawm cov dej tsis huv, xws li soot, uas tuaj yeem sib xyaw.
Lub cev qhuav dej thiab ziab: Siv lub tshuab nqus dej centrifugal zoo heev thiab lub tshuab ziab khaub ncaws, peb tuaj yeem txo cov dej noo ntawm desulfurized sludge gypsum los ntawm 10%, nqis mus rau hauv qab 1%, thiaj li ua tau raws li qhov xav tau ntau lawm.
Homogenization Nco ntsoov: Gypsum hmoov tom qab milling yuav raug xa mus rau homogenization silo los xyuas kom meej qhov siab tshaj plaws ntawm cov khoom zoo rau clinker yuav tsum tau. Thiab qhov no yog qhov tseem ceeb los xyuas kom meej tias qhov kev ua tau zoo ntawm cov khoom kawg tseem zoo li qub.
Lub desulfurized gypsum muaj qhov purity thiab lub cev ua yeeb yam sib npaug los yog zoo dua li cov Nature Gypsum qib II lossis siab dua, yog li siv tau los ua cov khoom siv zoo tshaj plaws rau kev ua gypsum board.
Environmental thiab Economic Benefits:
Kev txo qis hauv mining: Txhua tuj ntawm desulfurized gypsum siv txuag ntuj gypsum, uas tau muab rho tawm hauv av thiab tswj hwm thaj chaw ntuj thiab geological formations.
Kev txo cov khib nyiab: Hloov cov khoom pov tseg los ntawm cov khoom ua paug rau hauv cov khoom noj khoom haus qhia txog lub tswv yim kev lag luam ncig hauv kev nqis tes ua.
Cov Khoom Zoo: Vim yog qhov loj me me thiab ruaj khov ntawm desulfurized gypsum, peb cov gypsum board muaj cov qauv denser, muaj zog dua, thiab ua haujlwm zoo dua qub.
II. Zero Wastewater Discharge hauv Kev Tsim Khoom:
Nyob rau hauv lub ntiaj teb niaj hnub no, qhov twg cov dej muaj txiaj ntsig ntau dua, peb cov kab ntau lawm ua tiav qhov kev kaw tag nrho -loop recycling system rau cov txheej txheem dej khib nyiab, kom ntseeg tau tias "zero paug."
- Cov dej khib nyiab tuaj qhov twg?
Cov dej khib nyiab hauv gypsum board ntau lawm feem ntau yog los ntawm:
Cov khoom siv thiab cov kav dej ntxuav dej.
Dej ntws thiab dej ncig tshuab thaum lub sij hawm gypsum slurry npaj.
- Peb yuav ua li cas thiaj ua tau rov siv dua thiab rov siv dua?
Peb tau tsim ib qho kev sau thiab kho cov dej khib nyiab ywj pheej:
Sau thiab Sedimentation Cov dej khib nyiab ntau lawm yog sau rau hauv lub tank sedimentation qhov twg cov khoom raug tshem tawm (tseem ceeb gypsum) los ntawm ntuj txhais tau tias.
Neutralization thiab Refinement: Tus nqi pH rau cov dej khib nyiab uas tej zaum yuav tsis muaj zog acidic lossis tsis muaj zog alkaline thaum thawj txheej txheem raug kho kom nruab nrab nrog qhov tseeb.
Kaw Circuit Court Fibro 3Reuse: Tag nrho cov dej kho tau rov qab siv tau zoo - lub voj kaw. Tsis muaj cov txheej txheem dej khib nyiab raug xa tawm ntawm qhov chaw tsis siv vim yog fibrothionic gypsum thiab txhuam cov tshuab slurry tau ua tiav rov qab rau hauv cov txheej txheem ntau lawm, feem ntau yog siv rau kev tu cov cuab yeej thiab gypsum slurry npaj lub hom phiaj.
Core Values of this Initiative:
Kev Tiv Thaiv Kev Tiv Thaiv Dej: Qhov no txo qis kev siv dej tshiab rau kev tsim khoom, txo qhov siab ntawm cov chaw kho dej hauv zos.
Kev Tiv Thaiv Kev Ua Phem: Ua kom ntseeg tau tias cov khoom siv uas muaj peev xwm nqa tau thaum lub sijhawm tsim khoom tsis nkag mus rau sab nrauv dej, tiv thaiv cov av ib puag ncig thiab dej hauv av.
Txhim Kho Lub Zog Ua Haujlwm Zoo: Cov dej ntws mus rau hauv lub kaw lus kaw, txo qis kev siv hluav taws xob rau cua sov dej tshiab thiab txo qis cov pa roj carbon hneev taw ntxiv.
