Ekwelashweni kwegesi ye-flue yezimboni, uhlelo lwe-desulfurization ludlala indima ebalulekile, futhi ingxenye eyodwa ebonakala ingabalulekile - i-nozzle, ithinta ngokuqondile ukusebenza kahle nokuzinza kwalo lonke uhlelo. Eminyakeni yakamuva,i-desulfurization nozzles ezenziwe nge-silicon carbide materialkancane kancane ziye zaba intandokazi entsha embonini. Namuhla, ake sikhulume ngezici zabo eziyingqayizivele.
Iyini i-silicon carbide?
I-Silicon carbide (i-SiC) iyinhlanganisela eyakhiwe nge-silicon ne-carbon, enobulukhuni obuphakeme kakhulu kanye nokushisa okuphezulu okuhle kakhulu nokumelana nokugqwala. Ukuqina kwayo kwe-Mohs kuphakeme njengo-9.5, okwesibili ngemuva kwedayimane, okusho ukuthi ayigugi kakhulu. Ngesikhathi esifanayo, i-silicon carbide ingakwazi ukugcina ukuzinza ezindaweni zokushisa ezingaphezu kuka-1350 ℃, okuyinikeza inzuzo engokwemvelo ezimweni ezinzima zokusebenza.
Kungani ukhetha i-silicon carbide njenge-nozzle desulfurization?
Indawo yokusebenza yemibhobho ye-desulfurization ingachazwa ngokuthi "inzima":
-Ukuchayeka isikhathi eside kuma-slurries e-acidic kanye ne-alkaline egqwalayo
-Isivinini esikhulu sokugeza uketshezi
-Ukushintshashintsha kwezinga lokushisa okukhulu
-Ingaqukatha izinhlayiya eziqinile
Imibhobho yensimbi evamile ijwayele ukugqwala futhi iguge, kuyilapho imibhobho yepulasitiki ingakwazi ukumelana nokushisa. I-silicon carbide nozzle inxephezela ngokunembile lezi ziphutha, futhi izinzuzo zayo eziyinhloko zihlanganisa:
1. Ukumelana nokugqwala okuqinile
I-Silicon carbide inokumelana okuhle kakhulu nemithombo yezindaba ebolayo efana ne-asidi, i-alkali, nosawoti, futhi impilo yayo yesevisi idlula kude le yensimbi nemibhobho yepulasitiki.
2. Ukumelana nokugqoka okuhle kakhulu
Ngisho noma i-slurry iqukethe izinhlayiya eziqinile, i-silicon carbide nozzle ingagcina ukusebenza okuzinzile kokufafaza isikhathi eside futhi ayishintshwa kalula ku-angle yokufafaza ngenxa yokugqoka.
3. Ukusebenza kokumelana nokushisa okuphezulu
Ezindaweni ezishisa kakhulu zokushisa ezishisayo, imibhobho ye-silicon carbide ngeke igxumeke noma ithambe, iqinisekise imiphumela ezinzile yokufafaza.
4. Good conductivity ezishisayo
Isiza umlomo wombhobho ukuthi ukhiphe ukushisa ngokushesha futhi unciphise umonakalo wokucindezeleka okushisa.
Isimiso sokusebenza se-silicon carbide nozzle
I-silicon carbide desulfurization nozzle yenza i-desulfurization slurry (imvamisa i-limestone slurry) ibe amaconsi amancane, ahlangana ngokugcwele ne-flue gas, okubangele ukuthi izinto ze-alkaline eziku-slurry zisabele ngamakhemikhali ne-sulfur dioxide kugesi we-flue, ngaleyo ndlela kufezeke inhloso ye-desulfurization.
Idizayini nempahla ye-nozzle ithinta ngqo umphumela we-atomization:
-Ukuqina kwezinhlayiya ze-athomu, indawo yokuxhumana iba nkulu, kanye nokusebenza kahle kwe-desulfurization
-I-silicon carbide impahla iqinisekisa ukuzinza kwesikhathi eside kwembobo ye-nozzle, igwema ukwehla komphumela we-atomization ngenxa yokuguga nokudabuka.
Izimo zohlelo lokusebenza
Imibhobho ye-silicon carbide desulfurization isetshenziswa kabanzi ku:
-Thermal power plant
-Imboni yensimbi
-Imboni yokushisela udoti
-Eminye imikhakha yezimboni edinga i-flue gas desulfurization
Iziphakamiso zesondlo sansuku zonke
Nakuba imibhobho ye-silicon carbide inokuqina okuqinile, ukuhlolwa nokugcinwa njalo kusabalulekile:
-Hlola njalo ukuthi umlomo wombhobho uvaliwe noma ugugile
-Londoloza ukusebenza kahle kohlelo lokuhlunga udaka
-Shintsha i-nozzle ngokushesha lapho uthola ukwehla ekusebenzeni
isifinyezo
Nakuba i-silicon carbide desulfurization nozzle iyingxenye encane kuphela ohlelweni lwe-desulfurization, idlala indima ebalulekile ekuthuthukiseni ukusebenza kahle kwe-desulfurization kanye nokunciphisa izindleko zokusebenza. Isiphenduke inketho ekhethwayo emabhizinisini amaningi ngenxa yokumelana nokugqwala okuhle kakhulu, ukumelana nokuguga, nokumelana nezinga lokushisa eliphezulu.
Ukukhetha izinto ezifanele ze-nozzle kanye nomklamo akukwazi nje ukuthuthukisa izinkomba zemvelo, kodwa futhi kuletha izinzuzo zezomnotho zesikhathi eside ebhizinisini. Ezimfuneko zanamuhla eziqinile zemvelo, imibhobho ye-silicon carbide desulfurization iqapha buthule isibhakabhaka sethu esiluhlaza.
