Environmental teeb meem tabkaum kev loj hlob ntawm lub gravure luam lag luam tab sis kuj txhawb nws transformation thiab kho kom zoo dua
Nrog rau kev txhim kho ntawm lub sij hawm thiab kev txhim kho technology, hnub no, gravure printing, uas tau ua ntau txoj kev koom tes rau lub lag luam kev lag luam, tau ntsib cov teeb meem thiab kev cai raus dej ntawm kev ua lag luam tom qab kev loj hlob sai hauv 20 xyoo dhau los: Kev tiv thaiv ib puag ncig yog qhov teeb meem loj yog teeb meem loj gravure printing. Thaum ntxov li 20 xyoo dhau los, Cov teb chaws thiab cov teb chaws Europe tau tsim cov cai los tiv thaiv lub chaw, thiab ua rau cov kev cai thiab txwv rau VOC emissions. Hauv Suav teb, VOC emissions tswj tau cia li pib thiab ntau cov teeb meem yuav tsum tau daws; cov uas yuav tsum tau ua kom tsim tau lub zog huv thiab txo kev siv zog yog nyob hauv kev lag luam. Nrov suab nrov; khoom siv yuav tsum txawj ntse tshaj; kev thov kev lag luam rau cov khoom siv zoo, chaw ua haujlwm nce; cov neeg muas zaub xav kom tag nrho cov txheej txheem tsim los tswj tag nrho cov txheej txheem; "tus nqi ntau" yog qhov kev tshuaj xyuas tus neeg mob, txiav txim siab txog lawv txoj kev peev xwm Kev Nyuaj Siab ... Cov teeb meem zoo li no tsis zoo, tab sis tom qab ua tib zoo soj ntsuam thiab xaus, nws muaj peev xwm xaus tau tias qhov kev loj hlob zoo ntawm gravure printing yog: kev tiv thaiv, kev txuag lub zog, thiab ntse factories.
Kev tiv thaiv ib puag ncig
Xyoo 2012, lub Xeev Council tau pom zoo rau 12-Tsib-Xyoo Kev Npaj Rau Kev Tiv Thaiv thiab Kev Tswjhwm ntawm Kev Ua Phem Hauv Huab Cua Hauv Lub Nroog. Nws yog thawj zaug uas VOC kev tswj huab cua yog qhov tseem ceeb ntawm kev txhim kho tej yam kev txhim kho ntawm kev tsim kho. Thawj thawj zaug, kev kho VOCs thiab txo qis qis qis tau muab txhais meej meej hauv cov ntaub ntawv hauv teb chaws. lub hom phiaj. "Planning" tau hais tias "kev tswj cov pa paug dej tsis taus uas yog ib feem tseem ceeb ntawm kev txhim kho tej qhov dej num ntawm kev tsim kho, tsim koog paug tswj kev ntsuas", thiab muab tso rau cov chaw tseem ceeb tswj kev lag luam thiab cov tuam txhab loj huab cua, cov lag luam hauv cheeb tsam tseem ceeb, yuav raug nruj Saib xyuas thiab tswj. Cov kev qhia txog kev lag luam luam tawm xws li Beijing, cov tuam txhab luam ntawv uas twb muaj lawm, txhua tus siv 1 tuj ntawm hnyav ntxiv 2000 txog 2500 yuan dej phwj tuaj; Shanghai, yuav xyoo no Thaum xaus ntawm lub xyoo, VOC emissions los ntawm kev lag luam luam tawm raug txwv; nyob rau hauv Jiangsu, lub emission ntawm VOCs los ntawm kev lag luam luam yuav raug txwv nyob rau hauv nruab nrab-2016. Cov kev cai nruj no yog los txhawb kev lag luam khoom hloov khoom dua tshiab thiab neeg pom.
Kev kho kev kho rau VOCs muaj xws li rov qab thiab RTO thermal oxidation, tab sis Tuam Tshoj tus yees tsis yog ntse heev, muaj ntau yam teeb meem, xws li kev poob ceev ceev hauv cov adsorption, hnyav acidification, teeb meem kev nyab xeeb, thiab lig sib cais ntawm mixed solvents tsis yog daws, thiab ntau ntxiv. Qhov tseeb tiag, siv cov txheej txheem zoo thiab cov cuab yeej zoo siv yog txoj cai los daws qhov teeb meem. Tus kws sau ntawv ntseeg hais tias cov txheej txheem ntawm adsorption-rov qab-condensation-distillation yuav ua tau rau cov paug ntawm ib qho hnyav, kom cov tshuaj hnyav purity tau rov ua, uas yog ib puag ncig zoo thiab muaj txiaj ntsim zoo. Cov tshuaj xyaw xyaw, cov tshuaj RTO tuaj yeem siv coj mus ua dua tshiab hluav taws xob. Ntxiv rau, ua ntej qhov kev ua tiav ntawm ob lub VOCs kev ntsuas, cov cuab yeej uas twb muaj lawm tuaj yeem muab ntxiv nrog qhov ntxiv ntawm LEL Safety Circulator, uas yuav txo tau tshaj 40% ntawm VOCs rov qab thiab cov cuab yeej hluav taws xob RTO thermal oxidation.
Zog txuag
Thaum lub sij hawm luam ntawv, VOCs raug rho tawm thaum tseem siv cov nqi hluav taws xob ntau heev. Cov hluav taws kub lub zog yog lub latent heat ntawm vaporization ntawm qhov hnyav uas yuav tsum tau luam cov ziab nws tus kheej, thiab cov cua sov ntawm VOCs cov pa roj. Tshaj tawm raws li qhov nyiaj ntawm cov kob siv luam ntawv, cov kev ua cua sov ntawm cov xim yog 5 mus rau 10 KW, thiab ua rau lub zog ziab no feem ntau yog nyob rau ntawm 30 mus rau 72 KW los yog ntau dua. Lub zog yuav tsum tau rau kev ziab hauv kev lag luam luam rau 2% rau 5% ntawm tag nrho cov khoom muag khoom, txawm qhov nyiaj ntawm cov luam ntawv kev lag luam tseem khaws cia nyob rau theem no. Yog li no, yog tias muaj ib qho kev siv tshuab, qhov ziab tshev tawm ntawm cov txwm luam tau raug txo. Ib nrab, ces nws txhais tau hais tias lub tuam txhab cov profits yuav ob. Nyob rau hauv daim ntawv thov ntawm lub zog-saving kev ntsuas, Shaanxi Beiren tau coj tus hlau nyob rau hauv qhia txog ob txoj kev txuag hluav taws xob nyob hauv Suav teb: cov twj tso cua kub thiab cov kav dej kub. Thaum lub qhov ziab tshav kub yuav tsum tau luam tawm tsawg dua 100 ° C, yuav siv lub tshuab ua kom sov. Thaum twg ziab tshav kub yuav tsum luam tawm tau siab tshaj 100 ° C, ib qho kev siv tshav kub yog siv.
Thaum tshav kub kub twj
Thaum tshav kub kub twj feem ntau txuag 60% mus rau 70%. Tam sim no, 25% ntawm cov luam ntawv hauv lub teb chaws siv hluav taws xob ua cua sov. Yog tias cov tuam txhab luam ntawv hloov mus rau cov cua sov, lub teb chaws luam tawm kev lag luam yuav txuag tau 1.02 billion kWh ntawm hluav taws xob txhua xyoo, uas yog sib npaug ntawm tag nrho cov hluav taws xob tiam ntawm Liujiaxia hydropower chaw nres tsheb rau 2 lub hlis, sib npaug kom tsawg 100,000 tons ntawm carbon dioxide. Raws li lub Cuaj Hli xyoo no, lub teb chaws kub twj tso kua mis nruab tau muaj peev xwm tshaj 1,000 units.
Cua sov yeeb nkab
Cov tshuab raj tshuab ua haujlwm tau dav dav siv rau hauv aerospace, tub rog thiab lwm yam lag luam. Txij li nws tau nkag mus rau hauv lub tshuab hluav taws xob tsim, cov neeg tau hloov cov tswv yim tsim ntawm cov khoom siv hluav taws xob.
Txoj kev ua hauj lwm ntawm kev sib tw ntawm lub tshav kub hauv txauv hluav taws xob kub yog li nram qab no: lub cua tso pa dhau ntawm lub tshav kub ntawm lub tshav kub txeem hluav taws xob, qhov kawg ntawm lub yeeb nkab yog rhuab, cov kua nruab nrab hauv cov hlab ntim capillary sai sai, lwm qhov kawg (condensing kawg) nyob rau hauv qhov ntsuas me ntsis, thiab cua ntshiab dhau ntawm lub sijhawm ua kom haum, qhov nruab nrab ntawm cov kav dej kub thaum sov thiab txias rau hauv cov kua. Cov kua ntws rov qab mus rau qhov evaporation kawg raws qhov kev txiav txim siab ntawm cov khoom siv ntxig rau hauv cov kav dej kub. Cov voj voog no rov qab ua dua, thiab lub tshav kub yog hloov los ntawm ib qho kawg ntawm cov yeeb nkab mus rau lwm qhov kawg. . Lub tshav kub hloov ntawm kev tshav kub yog nyob ntawm theem hloov hauv nruab nrab ntawm cov yeeb nkab, uas yog txuag thiab sai, thiab nws qhov kev hloov hluav taws xob tuaj yeem ncav ntau tshaj 60%. Vim hais tias raws li txoj cai ntawm evaporation tsim, ntau dua qhov khiav hauj lwm kub cheeb tsam ntawm lub kub yeeb nkab, ntau pom tseeb lub zog-txuag cov nyhuv, thiab nws lub zog txuag yog feem ntau yog 35% mus rau 55%.
Ntse Hoobkas
Lub ntse tsim thiab ntse zauv uas tau ua ntawv thov nyob rau hauv lub ntsiab lus ntawm Kev Lag Luam Ntiaj Teb 4.0 tau ceev nrooj. Hnub no, ntau lub lag luam xws li tsheb tsim, tshuaj, kev lag luam, thiab lwm yam yog cov kev hloov, thiab lawv yuav mus rau Kev Lag Luam 4.0 vim kev lag luam 3.0. Cov lag luam luam ntawv sau tau ntawv zoo rau cov neeg ua haujlwm cov kev txawj thiab cov ntawv xov xwm ntws rau kev tsim khoom. Lawv yog cov neeg ua haujlwm, haus cov khoom siv hluav taws xob, loj thiab tsis kho, thiab tsis muaj kev lag luam competitiveness. Nws yuav hais tau tias Tuam Tshoj txoj kev lag luam luam tseem yog nyob rau hauv 2.x era, los yog qis dua. Raws li tus yam ntxwv ntawm kev lag luam luam, Shaanxi Beiren formulated tus qauv digital ua lag luam ntse ua qauv rau kev lag luam luam.
Kev lag luam thiab ntim ntse Hoobkas yog ib txoj haujlwm loj thiab loj heev, uas yog cov tswvcuab kev ua lag luam, kev tswj hwm software, cov ntaub ntawv sau khaws cia, thiab cov khoom siv tswv yim zoo. Los ntawm kev sib koom ua haujlwm ntawm ntau lub tshuab, ib lub siab ua haujlwm ntse ntse tau ua. Nyob hauv ib lub tsev ntse ntse, cov khoom siv thiab cov khoom siv sib txuas, cov neeg txuas nrog txhua tus, thiab cov neeg muaj kev cob cog rua cov khoom siv. Qhov ntawd yog, cov khoom hauv lub cev sib txuas lus sib txuas lus sib txuas lus nrog rau kev sib txuas lus thiab sib pauv lus sib hloov. Txhua lub hauv paus muaj kev sib nkag siab sib txuas.
Nyob rau hauv lub printing thiab ntim ntse lub Hoobkas, luam ntawv thiab ntim cov khoom siv tsis yog cov cuab yeej siv lossis ntau yam khoom loj, tab sis ib feem ntawm tag nrho cov txheej txheem ntawm kev txawj ntse. Tag nrho cov hauj lwm yog kev sib koom tes thiab kev xa tawm ntsej muag yog siv-thauj cov ntaub ntawv los ntawm lub tsev lag luam ntse los rau cov khoom siv luam ntawv; tus neeg teb xov tooj ntawm cov khoom siv luam ntawv tsis tas yuav thauj khoom thiab tawm lub yob, thiab cov cuab yeej ua ntse yuav tuaj yeem ua kom tiav cov yuaj thiab nce; cov txheej txheem tsis suav ntawm tag nrho cov cuab yeej raug xa los ntawm MES system. Rau lub cuab yeej, tus ntaus ntawv yuav tau nyeem thiab sau thiab ua tiav cov kev ntsuas qhov parameter. Nyob rau hauv no txoj kev, cov neeg tsav tsheb tsuas ua kev saib xyuas thiab soj ntsuam, uas yuav txo tau cov neeg ua hauj lwm hauv lub tuam txhab los ntawm 50%.
Kev tiv thaiv ib puag ncig, hluav taws xob txuag thiab ntse zov yog cov kev txhim kho yav tom ntej ntawm gravure printing. Nws ntseeg hais tias nrog cov kev tshaj tawm ntawm cov technologies saum toj no nyob rau hauv kev lag luam, cov tuam txhab luam ntawv yuav hloov thiab koom ua ke, cov lag luam hauv cheeb tsam thiab tsis muaj kev lag luam yuav raug yuam kom sib txuas thiab hloov, thiab kev sib tw ua lag luam yuav tsis sib haum.
