1.What yog cov pa phem tau ua los ntawm cov roj sib txuas?
Annealing Furnaces (tshwj xeeb tshaj yog cov khoom txuas ntxiv) feem ntau siv roj nkev (xws li coke cub roj), lossis cov roj me me tseem siv cov thee). Cov txheej txheem combusiontion tsim cov kuab paug hauv qab no:
Qhov teeb meem (PM₂.₅, PM₁₀): Tsis tiav cov roj (xws li roj thiab hnyav (carbon dub, thiab lwm yam kuab paug. Lub sijhawm ntev hluav taws xob yuav ua rau kom nce siab lub nroog atmospheric Partyrulation teeb meem ntau.
Sulphur oxides (so₂): Cov roj uas muaj cov txiv ntoo (xws li cov roj hnyav thiab cov leeg ntshav siab-sulfur thee) tsim kom muaj kev sib txuas. So₂ yog qhov tseem ceeb ua rau cov kua qaub cov kua thiab cov khoom siv kom haum thiab cov nroj tsuag ib puag ncig.
Nitrogen oxides (NOTₓ): Thaum lub tsheb khiav kub (tshwj xeeb yog cov pa roj oxide (nitrogen oxide (nitrogen oxide (NaP) Tsev cog khoom roj (CO₂): Cov khoom tseem ceeb ntawm cov pob zeb roj sib txuas, yog qhov xav tau thoob ntiaj teb uas yuav tsum tau tsom mus rau hauv "Ob lub hom phiaj ntawm" dual carbon "lub hom phiaj.
2.Qhov cov pa phem nyob rau hauv cov roj tso pa tawm?
Txhawm rau tiv thaiv oxidation ntawm steel sawb, ib lub nitrogen-hydrogen-hydrogen-hydrogen-hydrogen mixed tiv thaiv roj yog qhia rau hauv cov rauv rau hluav taws xob. Tsis tas li ntawd, rov qab muaj cov organic teeb meem ntawm sawb saum npoo, xws li dov roj thiab degatible cov neeg sawv cev, yuav xa tawm ntawm qhov kub thiab txias, tsim:
Cov organic cov cheeb tsam (vocs): cov roj av ntxhia thiab cov roj ntsha ua rau cov roj uas tsis yog quav tshuaj, qee qhov uas tuaj yeem koom nrog kev ua qias tuaj.
Cov roj uas tsis zoo ntawm cov pa roj teeb: piv txwv li, yog tias cov roj av muaj qhov tsis tiav
3.Qhov kev cuam tshuam dab tsi ua tus txheej txheem txias hauv lub annealing theem muaj nyob rau ntawm cov khoom siv dej?
Cua Txias Dej
Ceev sai txias (piv txwv li, qhov twg steel sawb yog txias los ntawm 800℃rau hauv qab txias) yuav tsum tau muaj ntau ntawm cov dej txias. Siv ib qho qhib lub tshuab cua txias (xws li lub zog txias (xws li lub tshuab cua txias - uas tuaj yeem ua rau muaj dej evapate, uas tuaj yeem ua rau cov dej evapate, tshwj xeeb hauv dej-thaj chaw.
Tso dej tawm kom tsawg
Yog tias cov dej txias ncig kom txias tsis yog kho kom zoo, nws tuaj yeem ua paug rau cov laj thawj hauv qab no:
Kev xau ntawm corrosion inhibitors (xws li chromates) thiab muab cov dej txias (xws li phosphitors) ntxiv rau cov dej txias lossis EUROPHIC paug ntawm lub cev dej;
Cov nqi me me ntawm cov noob zaub dej khov (xws li hydrochloric acid) seem ntawm cov npoo hlau tuaj yeem nkag mus rau cov pa dej txias nrog rau cov pH muaj nuj nqis thiab tsim acidic dej.
4.What yog cov khib nyiab hauv cov txheej txheem anealing?
Cov Ntaub Ntawv Pov Tseg Hluav Taws Xob Hluav Taws Xob
Annealing Rauv Cov Cua Sov thiab So kom sov thiab soaking txuas ntxiv cov khoom siv hluav taws xob txuas ntxiv) yog ua los ntawm cov khoom siv hluav taws xob txuas ntxiv) yog ua cov kab ke refractory thiab refractory fibers. Cov ntaub ntawv hnub nyoog thiab flake nyob rau hauv lub caij kub siab ntev, tsim cov ntaub ntawv pov khoom siv hluav taws xob hauv lub sijhawm hloov pauv. Yog tias cov ntaub ntawv no muaj cov asbestos (raws li pom hauv cov khoom qub), lawv xav tau kev phom sij los tiv thaiv asbestos fibers los ntawm paug huab cua.
Khib nyiab catalysts thiab adsorbents
Hauv qee cov txheej txheem anealing, cov thaiv cov roj (nitrogen-hydrogen-hydrogen-hydrogen-hydrogen-hydrogen-hydrogen-hydrogen-hydrogation (piv txwv li tshem tawm noo noo thiab CO₂). Adsorbents xws li molecular sieves thiab activated carbon ntau yuav siv, uas ua tau cov khib nyiab thaum cov khib nyiab. Yog tias hydrogen yog tsim los ntawm ammonia decomposition (muab cov catalmosition), xws li cov txheej txheem npib tsib xee) yuav tsum tau kho cov khoom pov tseg thaum cov khib nyiab uas muaj kev phom sij.
Lwm yam khib nyiab Slags
Slags los ntawm roj combusion (piv txwv li, cov roj av hnyav (piv txwv li cov roj av hnyav (piv txwv li cov roj av hnyav) tuaj yeem paug cov av thiab av tsis siv.
5.Txoj kev cuam tshuam dab tsi ua rau cov txheej txheem anealing muaj rau kev siv hluav taws xob thiab cov pa roj carbon monissions?
Noj kev txuas ntxiv txuas ntxiv rauv ua piv txwv, ua ib qho ntawm cov pa roj teeb), ua rau muaj kev sib tw ntawm cov khoom siv hluav taws xob (lossis siv cov roj carbon monission)
Yog tias qhov kev siv hluav taws xob ua kom muaj zog ntawm cov hluav taws xob thermal (cov hluav taws xob ua kom muaj zog ntxiv (cov hluav taws xob tawm rau cov hluav taws xob ua kom tawg
