Mu mankhwala a mpweya wotuluka m'mafakitale, njira yochotsera sulfur imagwira ntchito yofunika kwambiri, ndipo gawo limodzi losaoneka ngati lofunika kwambiri - nozzle, limakhudza mwachindunji magwiridwe antchito ndi kukhazikika kwa dongosolo lonse. M'zaka zaposachedwa,Ma nozzles opangidwa ndi silicon carbidePang'onopang'ono akhala otchuka kwambiri mumakampaniwa. Lero, tiyeni tikambirane za mawonekedwe awo apadera.
Kodi silicon carbide ndi chiyani?
Silicon carbide (SiC) ndi chinthu chopangidwa ndi silicon ndi carbon, chomwe chili ndi kuuma kwakukulu komanso kutentha kwambiri komanso kukana dzimbiri. Kuuma kwake kwa Mohs kuli pamwamba pa 9.5, chachiwiri pambuyo pa diamondi, zomwe zikutanthauza kuti sichimawonongeka kwambiri. Nthawi yomweyo, silicon carbide imatha kukhala yokhazikika pamalo otentha kwambiri opitilira 1350 ℃, zomwe zimapatsa mwayi wachilengedwe m'malo ovuta kugwira ntchito.
Nchifukwa chiyani mungasankhe silicon carbide ngati nozzle yochotsera sulfurization?
Malo ogwirira ntchito a nozzles ochotsera sulfurization angatanthauzidwe ngati "ovuta":
-Kukhala ndi asidi ndi alkaline kwa nthawi yayitali
-Kutsuka madzi mwachangu kwambiri
-Kusinthasintha kwakukulu kwa kutentha
-Ikhoza kukhala ndi tinthu tolimba
Ma nozzle achitsulo achikhalidwe amatha kuwononga ndi kuwonongeka, pomwe ma nozzle apulasitiki satha kupirira kutentha. Nozzle ya silicon carbide imakwaniritsa bwino zofooka izi, ndipo zabwino zake zazikulu ndi izi:
1. Kukana dzimbiri kwamphamvu kwambiri
Silicon carbide imalimbana bwino ndi zinthu zowononga monga asidi, alkali, ndi mchere, ndipo nthawi yake yogwira ntchito imaposa nthawi ya chitsulo ndi pulasitiki.
2. Kukana bwino kuvala
Ngakhale slurry ili ndi tinthu tolimba, nozzle ya silicon carbide imatha kusunga ntchito yopopera yokhazikika kwa nthawi yayitali ndipo siisintha mosavuta mu ngodya yopopera chifukwa cha kuwonongeka.
3. Kugwira ntchito kolimba kwa kutentha
M'malo otentha kwambiri okhala ndi mpweya wofewa, ma nozzles a silicon carbide sadzasintha kapena kufewa, zomwe zimapangitsa kuti kupopera kukhale kokhazikika.
4. Kutulutsa bwino kutentha
Zimathandiza kuti nozzle ichotse kutentha mwachangu ndikuchepetsa kuwonongeka kwa kutentha.
Mfundo yogwirira ntchito ya nozzle ya silicon carbide
Kamba ka silicon carbide desulfurization kamapangitsa kuti slurry ya desulfurization (nthawi zambiri imakhala slurry ya limestone) ikhale madontho ang'onoang'ono, omwe amakhudzana kwathunthu ndi mpweya wa flue, zomwe zimapangitsa kuti zinthu za alkaline zomwe zili mu slurry zigwirizane ndi sulfur dioxide mu mpweya wa flue, motero kukwaniritsa cholinga cha desulfurization.
Kapangidwe ndi zipangizo za nozzle zimakhudza mwachindunji zotsatira za atomization:
-Tinthu ta atomu tomwe timapangidwa bwino kwambiri, malo olumikizirana amakhala akulu, komanso mphamvu ya desulfurization imakhala yokwera.
-Zinthu zopangidwa ndi silicon carbide zimatsimikizira kukhazikika kwa nthawi yayitali kwa nozzle aperture, kupewa kuchepa kwa atomization effect chifukwa cha kuwonongeka ndi kung'ambika.
Zochitika zogwiritsira ntchito
Ma nozzles a silicon carbide desulfurization amagwiritsidwa ntchito kwambiri mu:
-Mafakitale opangira magetsi
-Chomera chachitsulo
-Fakitale yowotcha zinyalala
-Magawo ena a mafakitale omwe amafunikira kuchotsedwa kwa mpweya woipa
Malangizo okonza tsiku ndi tsiku
Ngakhale kuti nozzles za silicon carbide zimakhala zolimba kwambiri, kuyang'anira ndi kukonza nthawi zonse ndikofunikirabe:
-Nthawi zonse onani ngati nozzle yatsekedwa kapena yatha
-Pitirizani kugwira ntchito bwino kwa makina osefera a slurry
-Bwezerani nozzle mwachangu mukazindikira kuchepa kwa magwiridwe antchito
chidule
Ngakhale kuti nozzle ya silicon carbide desulfurization ndi gawo laling'ono chabe mu dongosolo la desulfurization, imagwira ntchito yofunika kwambiri pakukweza magwiridwe antchito a desulfurization ndikuchepetsa ndalama zogwirira ntchito. Yakhala chisankho chomwe chimakondedwa ndi mabizinesi ambiri chifukwa cha kukana dzimbiri, kukana kuvala, komanso kukana kutentha kwambiri.
Kusankha zipangizo zoyenera zotulutsira mpweya ndi kapangidwe kake sikungowonjezera zizindikiro zachilengedwe zokha, komanso kumabweretsa phindu lachuma kwa nthawi yayitali ku bizinesi. Masiku ano, malinga ndi malamulo okhwima okhudza chilengedwe, ma nozzles a silicon carbide desulfurization akuteteza thambo lathu labuluu mwakachetechete.
