Esigcawini se-Blue Sky Defense Battle, kukhona 'umnumzana obalulekile' owaziwa kancane oqaphe impilo yethu yokuphefumula - akuwona umbhoshongo omkhulu wokumunca noma uhlelo lokulawula oluyinkimbinkimbi, kodwaflue gas desulfurization nozzle (FGD spray nozzle)ngobubanzi obungamashumi ambalwa kuphela wamamilimitha - le ngxenye encane engabonakali iwumgogodla wokusebenza kahle kwalo lonke uhlelo lwe-desulfurization.
“Njengomphimbo” wesistimu ye-desulfurization, umlomo wombhobho udinga ukumelana “nokuhlolwa okuthathu” kwezinga lokushisa eliphezulu, ukugqwala okuqinile, nokuguga okuphezulu. Izinto zensimbi zendabuko zivame ukuba nezinkinga ezifana nokunwetshwa kosayizi wezimbotshana kanye nokwehluleka kwe-atomization ngemva kwezinyanga ezimbalwa zokuguguleka yi-acidic slurries; Nakuba amapulasitiki obunjiniyela ekwazi ukumelana nokugqwala, kunzima ukumelana namazinga okushisa aqhubekayo. Ngalesi sikhathi, impumelelo eyimpumelelo evela kusayensi yezinto zesimanje - i-reaction sintered silicon carbide ceramics, ibhala kabusha izindinganiso zemboni.
Lolu hlobo olusha lwe-ceramic, olwaziwa ngokuthi "igolide elimnyama lezimboni," libonisa izici ezimangalisayo ezingeni le-microscopic: izigidi zamakristalu e-silicon carbide akha inethiwekhi ecinene ngezinqubo ezikhethekile zokucwilisa, okwenza ubulukhuni obufana nedayimane. Lapho i-desulfurization slurry equkethe izinhlayiya ze-gypsum ishaywa ngomfutho ophezulu kanye nesivinini, izinga layo lokugqoka liphansi kakhulu kunelensimbi evamile. Okubaluleke nakakhulu, “inamandla amakhulu” emvelo okumelana nokugqwala kwe-asidi ne-alkali, futhi ingagcina umzimba wayo ongabhubhi ngisho nangaphansi kwezimo zokuguquguquka okukhulu kwe-pH.
Mayelana nokuzinza, le nto ibonisa impilo yesevisi emangalisayo. Ukuchezuka kwe-engeli ye-atomization yalo mbhobho wento zisalawulwa phakathi kwebanga elincane kakhulu ngemva kweminyaka embalwa, futhi leli khono lokugcinwa elinemba linweba umjikelezo wokulungisa imishini izikhathi ezimbalwa.
Kumakhasimende adinga ukusebenzisa izinhlelo ze-desulfurization, ukukhetha imibhobho ye-silicon carbide kufana nokuthenga "umshwalense wesikhathi sonke" wezinto zokusebenza. Akunciphisi nje kuphela izindleko zokushintshwa kwezingxenye eziyisipele, kodwa okubaluleke nakakhulu, kuqinisekisa ukuzinza okuqhubekayo kokusebenza kahle kwe-desulfurization - okuhlobene ngokuqondile namazinga okuvikela imvelo kanye nokukhiqizwa okuqhubekayo kwamabhizinisi.
Izingxenye zomlomo ezikhiqizwe kusetshenziswa ubuchwepheshe bemishini yokunemba obunelungelo lobunikazi zithola izivivinyo ezinzima eziningi, okuhlanganisa nokuhlolwa kwe-athomu, ngaphambi kokuphuma efekthri ukuze kuqinisekiswe ukuthi izinzuzo ezingokwemvelo zezinto ziguqulwa zibe izinzuzo ezibonakalayo zemvelo.
Ohambweni olusha oluholwa umgomo “wekhabhoni embaxambili”, ukusungulwa okusha kwezobuchwepheshe kufaka ubungqabavu obuhlala njalo ezintweni zokuvikela imvelo. Ukusetshenziswa okusabalele kwe-reaction sintered silicon carbide ceramic nozzles kuwumbhalo waphansi ocacile wenguquko yezinto ezibonakalayo enika amandla ukukhiqizwa okuluhlaza. Uma sibheka phezulu esibhakabhakeni esiluhlaza esicacile, singase sicabange ngalaba "abagadi be-ceramic" abafihle amakhono abo nodumo - baqapha ubumsulwa bezinkulungwane zamamitha ngokukhuthazela kwezinga lamamilimitha.
