Kev loj hlob ruaj khov
Txhua yam khoom siv yeeb nkab tuaj yeem siv tau los ntawm tib neeg mus ib txhis, qhov laj thawj tseem ceeb tshaj plaws yog tias nws tuaj yeem rov siv dua thiab rov siv dua thiab tsis tsim cov pa phem tshiab. Feem ntau ntawm cov ntaub ntawv tsis tuaj yeem rov tsim dua tshiab tom qab siv. Txawm hais tias qee qhov ntawm lawv tuaj yeem siv tau ib nrab, lawv tsis tuaj yeem ua tiav cov khoom siv raw ntawm cov khoom kom muaj nuj nqis thiab zoo, siv ntau lub zog thiab ua cov nqi, thiab feem ntau yuav ua rau muaj kuab paug. Piv txwv li, qee cov kav dej yas muaj pov tseg lossis cov kav dej qub uas tsis tuaj yeem rov ua dua lossis degradable, ua rau muaj kev kub ntxhov rau ib puag ncig. Thiab ntau dua 90% ntawm lub ntiaj teb tooj liab tuaj yeem yaj rau hauv cov tooj liab rov qab siv dua. Recycled tooj liab tuav tag nrho cov khoom zoo tshaj plaws ntawm tus thawj tooj liab, tso cai rau cov tooj liab kom rov ua dua tshiab. Txhim kho cov kav dej tooj liab thiab fittings hauv ib lub tsev yog sib npaug rau kev nqis peev "txuag". Ntau xyoo tom qab, thaum lub tsev puas lawm thiab tag nrho lwm yam khoom siv thiab cov khoom siv tsis muaj txiaj ntsig, cov yeeb nkab tooj liab tseem muaj txiaj ntsig siv.
Tshwj xeeb, nws yuav tsum tau taw qhia tias tooj liab yuav tsis tsim cov pa roj carbon monoxide lossis lwm yam khoom tsis zoo lossis lwm yam pov tseg thaum lub sijhawm rov tsim dua tshiab. Tib hom "kev phooj ywg" rau ib puag ncig tsis muaj nyob rau hauv lwm cov ntaub ntawv. Vim yog qhov zoo ntawm cov kav dej tooj liab saum toj no, lawv tau siv dav hauv kev tsim cov kav dej kub thiab txias hauv cov teb chaws tsim thiab thaj chaw hauv ntiaj teb. Nrog rau kev txhim kho txuas ntxiv ntawm cov pej xeem Suav paub txog cov kav dej tooj liab, kev tsim vaj tsev zoo li dhau los ua ib qho kev sib tw thoob ntiaj teb. Cov kav dej yuav yeej coj tau lub tswv yim tshiab ntawm cov kav dej noj qab haus huv hauv lub xyoo pua 21st.
Daim ntawv thov kev cia siab
Cov kws tshaj lij tau taw qhia tias, raws li txoj kev loj hlob ntawm Tuam Tshoj lub tshuab cua txias thiab lwm yam kev lag luam, Tuam Tshoj tooj liab yeeb nkab lag luam tau zais kev lag luam txawm tias muaj kev hloov pauv, thiab 10 xyoo tom ntej no yuav yog lub sijhawm tseem ceeb rau kev txhim kho Tuam Tshoj cov yeeb nkab tooj liab. kev lag luam. Tsis tas li ntawd, kev sib koom ua ke, kev tsim kho, thiab kev tsim kho tshiab ntawm cov tuam txhab lag luam yuav dhau los ua tus qauv ntawm kev lag luam txoj kev loj hlob, thiab nkag mus rau kev lag luam txawv teb chaws yuav dhau los ua qhov kev xaiv tsis raug rau kev tsim kho kev lag luam. Tuam Tshoj tooj liab yeeb nkab kev lag luam tau ua tiav ib qho zoo leap hauv kev tsom xam ntawm cov kws tshaj lij. Copper yeeb nkab yog ib qho ntawm cov khoom lag luam loj tshaj plaws hauv Suav teb cov khoom siv tooj liab ua ntau lawm. Xyoo 2002, Tuam Tshoj txoj kev tsim cov yeeb nkab tooj liab tau ze rau 1/5 ntawm lub ntiaj teb tag nrho cov yeeb nkab tooj liab tsim. Raws li kev kwv yees ntawm 27 lab lub tshuab cua txias hauv Suav teb xyoo 2002, kev siv cov kav dej zoo tib yam hauv cov xov tooj liab ib leeg mus txog 54,000 tons.
Yog li ntawd, yog tias Tuam Tshoj cov cua txias tso zis tau mus txog 30.5 lab units hauv xyoo 2005, ces tus nqi ntawm cov khoom siv hauv cov xov tooj liab zoo tib yam yuav nyob ze rau 92,000 tons. Yog li ntawd, cov kws tshaj lij kev lag luam ntseeg tias 10 xyoo tom ntej no yuav yog lub sijhawm tseem ceeb rau kev txhim kho Tuam Tshoj txoj kev lag luam yeeb nkab tooj liab. Cov zis ntawm Tuam Tshoj cov kav dej tooj liab yuav loj hlob ntawm qhov nruab nrab ntawm 5% hauv ib xyoos, thiab qhov kev loj hlob no tseem tuaj yeem ncav cuag 8 ua ntej 2005. %. Raws li kev taw qhia ntawm Lub Tsev Haujlwm Saib Xyuas Kev Tshawb Fawb Copper Pipe ntawm Tuam Tshoj Industrial Products Production License Office, tam sim no muaj 260 tuam txhab uas muag tau thov rau daim ntawv pov thawj ntawm cov ntawv tso cai ntawm cov yeeb nkab tooj liab. Nws yog kwv yees los ntawm qhov no tias yuav tsum muaj txog 300 Suav tooj liab yeeb nkab ntau lawm tuam txhab. Raws li qhov tseeb cov ntaub ntawv tsom xam ntawm CRU, Tuam Tshoj tau dhau los ua qhov thib ob loj tshaj plaws tooj liab raj tsim thiab siv lub teb chaws hauv ntiaj teb tom qab Tebchaws Meskas. Hauv xyoo 2002, kev tsim khoom thiab kev siv cov raj tooj liab tau mus txog 460, 000 tons thiab 481,{16}} tons raws li, piv nrog rau xyoo 2001 Piv nrog rau xyoo dhau los, kev loj hlob tau nce siab txog 15% thiab 10. % raws. Yog hais tias xam ntawm qhov nruab nrab txhua xyoo kev loj hlob ntawm 8%, tag nrho cov kev siv ntawm Suav tooj liab kav xyoo 2005 thiab 2010 yuav ncav cuag 560, 000 tons thiab 820, 000 tons, raws li, qhia tau hais tias Tuam Tshoj tus tooj liab yeeb nkab kev ua lag luam yog dav heev. Tom qab kev hloov pauv thev naus laus zis thiab kev nthuav dav hauv 10 xyoo dhau los, kev tsim cov tooj liab coils hauv Suav teb tau hloov pauv zoo heev, thiab cov khoom tsim tawm thiab kev ua tau zoo tau ua keeb kwm leaps, pib mus txog lub ntiaj teb qib siab. Raws li kev txheeb cais tsis tiav, txij li thaum kawg ntawm xyoo 2002, Tuam Tshoj tus tooj liab coil muaj peev xwm tsim tau txog 300,{30}} tons, qeb thib ib hauv ntiaj teb; tam sim no qhov tseeb ntawm cov tooj liab coils yog kwv yees li 120, 000 tons, ntawm cov xov hauv xov tooj yog li 60,{34}} tons. Tsis tsuas yog nws tuaj yeem ua tau raws li qhov xav tau ntawm kev lag luam hauv Suav teb, tab sis kuj muaj qee cov khoom xa tawm mus rau txawv teb chaws. Muaj zog thov rau high-efficiency tshav kub dissipation tooj liab tubes Nyob rau hauv xyoo tas los no, ntxiv rau qhov poob ntawm tooj liab raj nyob rau hauv Western lub teb chaws nyob rau hauv lub xyoo los ntawm lub xyoo, thiab kev sib tsoo loj heev ntawm smuggling, kev loj hlob tus nqi ntawm Tuam Tshoj lub tshuab cua txias tsim kev loj hlob tau tsim ib tug zoo heev. ntau lawm rau Tuam Tshoj tus tooj liab coil ntau lawm. lub sijhawm.
Nyob rau hauv 1998, tag nrho cov zis ntawm Tuam Tshoj lub tshuab cua txias tshaj 10 lab units, nyob rau hauv 2001 nws tshaj 26 lab units, thiab nyob rau hauv 2002 nws tshaj 30 lab units. Tam sim no, Tuam Tshoj lub peev xwm ntau lawm yog li 40 lab units. Txhawm rau hloov mus rau kev txhim kho ntawm kev lag luam cua txias, raws li qhov kawg ntawm 2000, Tuam Tshoj tus tooj liab coil thiab lub tshuab cua txias raj muaj peev xwm tau nce mus rau 280,{35}} tons, nce ntxiv. ntawm li 4 npaug piv nrog rau xyoo 1990. Copper coils muaj kev ua haujlwm ruaj khov, muaj tus kheej zoo, cov khoom siv siab blanking lub sij hawm thiab siab yield tus nqi. Yog li ntawd, feem ntau cov tshuab cua txias tshuab siv tooj liab coil hnyav ntawm 100-200 kg. Txhawm rau txhawm rau txhim kho cov thermal efficiency thiab txuag hluav taws xob, thiab tsim cov khoom siv hluav taws xob zoo, txuag hluav taws xob thiab ib puag ncig-phooj ywg cua txias, nws yog ib qho tsim nyog yuav tsum tau siv cov xov tooj tooj cua sab hauv. Piv nrog rau cov raj du, thaj chaw sab hauv yog nce 2 mus rau 3 zaug. Tsis tas li ntawd, cov xov sab hauv ua rau qhov nruab nrab los tsim cov dej ntws tawm thiab ua kom nws cov dej ntws nrawm, kom cov thermal conductivity zoo heev piv nrog cov yeeb nkab du ntawm tib cov lus qhia, uas ua rau kom cov thermal efficiency nce 20% {{22} }% thiab txuag tau 15% zog. Raws li qhov kawg ntawm xyoo 2002, kev siv cov xov tooj cua sab hauv hauv cov tshuab cua txias tau mus txog 50% ntawm tag nrho cov kev siv tooj liab, thiab kwv yees li 60% hauv xyoo 2003 (lub tshuab cua txias tseem ceeb tau mus txog kev siv. threaded raj hauv 2003 70%), nws yuav siab li 80% los ntawm 2005. Yog hais tias, nyob rau hauv 2001, 2002 thiab 2005, tag nrho cov kev thov rau tooj liab coils ntawm lub tshuab cua txias yog 60,{{37} } tons, 80,000 tons thiab 150,{41}} tons raws li, ntawm qhov kev thov tag nrho rau cov xov tooj hauv xov tooj ntawm tes yuav ncav cuag 30,000 tons, 50,{{45} } tons thiab 120,000 tons. Nkag mus rau kev ua lag luam txawv teb chaws tau dhau los ua kev xaiv rau kev txhim kho kev lag luam. Los ntawm qhov kev xav ntawm kev ua lag luam thiab kev xav tau, Tuam Tshoj cov tooj liab coils tau tshaj cov khoom siv. 2002 yog lub xyoo sib tw tshaj plaws hauv Tuam Tshoj txoj kev lag luam tooj liab. Ntawm qhov tod tes, kev txhim kho tas mus li ntawm Tuam Tshoj txoj kev lag luam cua txias tau tsav qhov kev loj hlob tsis tu ncua ntawm Tuam Tshoj cov yeeb nkab tooj liab noj, muab kev lag luam loj loj thiab kev tsim kho rau cov tooj liab coils; ntawm qhov tod tes, nrog rau kev nce qib ntawm cov tshuab cua txias tsim tshuab, qhov zoo thiab cov kev xav tau tau nce siab dua, thiab cov qauv kev lag luam ntawm cov khoom siv ntau dhau tau txhawb kev sib tw hauv cov yeeb nkab tooj liab ua lag luam los txhim kho txhua hnub, yuam ntau yam. cov tuam txhab tsim khoom kom tsis tu ncua txhim kho lawv cov cuab yeej siv cuab yeej thiab nrhiav txoj hauv kev tawm ntawm kev lag luam nplai thiab cov khoom lag luam zoo. Kev ua lag luam tau dhau los ua kev teeb tsa ntawm Tuam Tshoj. Lub cev tseem ceeb ntawm cov yeeb nkab tooj liab ntau lawm. Cov kws tshaj lij kwv yees tias nyob rau hauv 10 xyoo tom ntej, thaum cov zis yuav nce sai, ntau yam, ntau lawm technology thiab khoom siv ntawm Tuam Tshoj cov kav dej tooj liab kuj yuav hloov raws li. Ntawm lawv, cov cua txias cua txias cua sov yeeb nkab yuav maj mam paub tag nrho cov xov sab hauv, thiab yuav txhim kho mus rau cov kev taw qhia ntawm me me txoj kab uas hla, complex hniav zoo, siab kub dissipation thiab siab huv. Nyob rau tib lub sijhawm, kev tsim khoom thiab kev siv cov vuam siv hluav taws xob muaj txiaj ntsig zoo rau cov kav dej thiab cov kav dej finned sab nraud kuj tseem yuav ua tiav Kev Ua Haujlwm Zoo. Nyob rau tib lub sijhawm, thev naus laus zis thiab cov cuab yeej siv qib ntawm Tuam Tshoj cov yeeb nkab tooj liab ntau lawm kuj tseem yuav txhim kho, uas yog, kab rov tav casting-planetary dov-coil daim duab thiab nce-kos duab txias ua cov txheej txheem yuav tau txais kev mloog ntau dua los ntawm cov lag luam.
