Ekwelashweni kwegesi yoketshezi lwezimboni, uhlelo lokususa i-sulfur ludlala indima ebalulekile, kanti ingxenye eyodwa ebonakala ingabalulekile - i-nozzle, ithinta ngqo ukusebenza kahle kanye nokuzinza kohlelo lonke. Eminyakeni yamuva nje,ama-nozzle okususa i-sulfurization enziwe ngezinto ze-silicon carbidekancane kancane sezibe yintandokazi entsha embonini. Namuhla, ake sixoxe ngezici zazo eziyingqayizivele.
Kuyini i-silicon carbide?
I-silicon carbide (SiC) iyinhlanganisela eyakhiwe yi-silicon ne-carbon, enobulukhuni obuphezulu kakhulu kanye nokumelana nokushisa okuphezulu nokugqwala okuhle kakhulu. Ubulukhuni bayo be-Mohs bufinyelela ku-9.5, bulandela idayimane kuphela, okusho ukuthi ayigugi kakhulu. Ngesikhathi esifanayo, i-silicon carbide ingagcina ukuqina ezindaweni ezinokushisa okuphezulu ezingaphezu kuka-1350 ℃, okuyinika inzuzo yemvelo ezimweni zokusebenza ezinzima.
Kungani ukhethe i-silicon carbide njengomlomo wokususa i-sulfurization?
Indawo yokusebenza yama-nozzles okususa i-sulfur ingachazwa ngokuthi “inzima”:
-Ukuchayeka isikhathi eside ezingcoleni ezibolayo ezine-asidi ne-alkaline
-Ukuhlanza uketshezi ngesivinini esikhulu
-Ukuguquguquka okukhulu kwezinga lokushisa
-Kungase kube nezinhlayiya eziqinile
Ama-nozzle ensimbi endabuko avame ukugqwala nokuguguleka, kuyilapho ama-nozzle epulasitiki engenawo ukumelana nokushisa. I-nozzle ye-silicon carbide ilungisa kahle la maphutha, futhi izinzuzo zayo eziyinhloko zifaka:
1. Ukumelana nokugqwala okunamandla kakhulu
I-silicon carbide inokumelana okuhle kakhulu nezinto ezigqwalisayo ezifana ne-asidi, i-alkali, nosawoti, futhi isikhathi sayo sokusebenza sidlula kakhulu isikhathi sama-nozzle ensimbi nepulasitiki.
2. Ukumelana okuhle kakhulu kokugqokwa
Ngisho noma i-slurry iqukethe izinhlayiya eziqinile, i-nozzle ye-silicon carbide ingagcina ukusebenza okuzinzile kokufutha isikhathi eside futhi ayishintshi kalula ekhoneni lokufutha ngenxa yokuguguleka.
3. Ukusebenza kokumelana nokushisa okuphezulu
Ezindaweni ezinegesi yoketshezi eshisa kakhulu, ama-nozzle e-silicon carbide ngeke ashintshe noma athambe, okuqinisekisa imiphumela yokufafaza eqinile.
4. Ukuqhuba kahle kokushisa
Kusiza i-nozzle ukuthi ikhiphe ukushisa ngokushesha futhi inciphise umonakalo wokucindezeleka kokushisa.
Isimiso sokusebenza se-silicon carbide nozzle
I-nozzle ye-silicon carbide desulfurization i-atomize i-desulfurization slurry (ngokuvamile i-limestone slurry) ibe amaconsi amancane, ahlangana ngokugcwele negesi ye-flue, okwenza izinto ze-alkaline ku-slurry zisabele ngamakhemikhali ne-sulfur dioxide kugesi ye-flue, ngaleyo ndlela kufezwe injongo ye-desulfurization.
Umklamo kanye nezinto zombhobho zithinta ngqo umphumela we-atomization:
-Uma izinhlayiya ze-atomized zicolekile, indawo yokuxhumana inkulu, futhi ukusebenza kahle kwe-desulfurization kuyanda.
-Izinto ze-silicon carbide ziqinisekisa ukuzinza kwesikhathi eside kwembobo yomlomo, zigwema ukwehla komphumela we-atomization ngenxa yokuguguleka nokuqhekeka.
Izimo zohlelo lokusebenza
Ama-nozzles e-silicon carbide desulfurization asetshenziswa kabanzi ku:
-Isitshalo samandla okushisa
-Isitshalo sensimbi
-Indawo yokushisa udoti
-Eminye imikhakha yezimboni edinga ukususwa kwegesi yoketshezi
Iziphakamiso zokunakekelwa kwansuku zonke
Nakuba ama-nozzle e-silicon carbide ehlala isikhathi eside, ukuhlolwa nokugcinwa njalo kusabalulekile:
-Hlola njalo ukuthi umlomo uvaliwe noma ugqokile
-Gcina ukusebenza kahle kohlelo lokuhlunga i-slurry
-Shintsha i-nozzle ngokushesha uma uthola ukuthi ukusebenza kwayo kwehla
isifinyezo
Nakuba i-nozzle ye-silicon carbide desulfurization iyingxenye encane nje ohlelweni lwe-desulfurization, idlala indima ebalulekile ekuthuthukiseni ukusebenza kahle kwe-desulfurization kanye nokunciphisa izindleko zokusebenza. Sekuyisinqumo esikhethwayo samabhizinisi amaningi ngenxa yokumelana kwayo okuhle kakhulu nokugqwala, ukumelana nokuguguleka, kanye nokumelana nokushisa okuphezulu.
Ukukhetha izinto ezifanele zombhobho kanye nomklamo ngeke nje kuthuthukise izinkomba zemvelo, kodwa futhi kuzokwenza ibhizinisi libe nezinzuzo zezomnotho zesikhathi eside. Ezidingweni zemvelo zanamuhla eziqinile, imibhobho yokususa i-silicon carbide desulfurization ivikela buthule isibhakabhaka sethu esiluhlaza okwesibhakabhaka.
