Lefatšeng le leholo la tlhahiso ea indasteri, lihokelo tse ngata tsa bohlokoa li ke ke tsa etsa ntle le ts'ehetso ea lisebelisoa tse phahameng tsa ts'ebetso. Kajeno, re tla hlahisa boitsebiso bo nang le karolo ea bohlokoa liindastering tsa setso tse kang li-kilns le tsamaiso ea desulfurization -karabelo sintered silicon carbide ceramics.
silicon carbide ceramic ke eng?
Silicon carbide ceramic ke thepa e tsoetseng pele ea ceramic e entsoeng ka silicon le carbon. Ha se ceramic e tloaelehileng, empa ke "metamaterial" e nang le lisebelisoa tse ngata tse ntle haholo. E na le litšoaneleho tsa matla a mocheso o phahameng, ho hanyetsa ho apara hantle, coefficient e tlase ea ho atolosa mocheso, boima bo phahameng, le khanyetso ea ho senya lik'hemik'hale, e leng se etsang hore e hlahelle har'a lisebelisoa tse ngata.
Reaction sintered silicon carbide ceramics ke mofuta o khethehileng oa silicon carbide ceramics, 'me mokhoa oa bona oa ho lokisetsa o ikhetha haholo - pele, likaroloana tse ntle tsa alpha SiC le li-additives li hatelloa' meleng o motala, ebe li kopana le silicon ea metsi ka mocheso o phahameng. Ka nako ena, carbon e se nang letho e na le ts'ebetso e babatsehang ea lik'hemik'hale ka Si e kentsoeng, e hlahisang β - SiC 'me e tlamahane ka thata le α - SiC. Ka nako e ts'oanang, silicon e sa lefelloeng e tlatsa li-pores, qetellong e fumana thepa ea ceramic e teteaneng haholo.
Lejoe la motheo seboping
Rection sintering ea silicon carbide ceramics ke karolo ea bohlokoa ebile ea bohlokoa libonong tse fapaneng tsa mocheso o phahameng. Mohlala, ka litlolong tsa tlhahiso ea ceramic joalo ka li-roller kilns, kilns, li-shuttle kilns, joalo-joalo, e entsoe ka likarolo tsa bohlokoa joalo ka matsoho a nozzle, lirolara tsa crossbeam le liphaephe tsa moea tse batang.
Sleeve sa nozzle ea lelakabe le ka laola ka nepo ho leka-lekana ha mocheso ka har'a sebōpi. E na le litšobotsi tsa matla a mocheso o phahameng, ho hanyetsa oxidation, ho hanyetsa ho apara, le ho hanyetsa ho pholile ka potlako le ho futhumatsa. E ke ke ea robeha kapa ea senyeha ka mor'a tšebeliso ea nako e telele ea mocheso o phahameng, ho netefatsa tikoloho e tsitsitseng ea mocheso ka har'a sebōpi. E bohlokoa bakeng sa ho chesa lihlahisoa tsa boleng bo holimo tsa ceramic.
Lirolara tsa crossbeam le likotopo tsa moea tse batang ka ho latellana li na le boikarabelo ba bohlokoa ba ho tšehetsa le ho kenya moea. Crossbeam roller e na le litšobotsi tsa botsitso bo botle ba mocheso, ho hanyetsa oxidation, le ho hanyetsa mocheso o phahameng oa mocheso. Ha ho bonolo ho holofatsa le ho khumama ka mor'a tšebeliso ea nako e telele mochesong o phahameng, ho netefatsa botsitso ba sebopeho sa ka hare sa sebōpi le lipalangoang tse boreleli. Setsi sa moea se batang se na le boikarabello ba ho laola phallo ea khase le kabo ea mocheso ka har'a sebōpi, ho netefatsa ts'ebetso e tloaelehileng ea sebōpi.
Ho latela pono ea likarolo tse ikhethileng, reaction sintered silicon carbide e na le melemo e hlakileng tlhahisong ea likarolo tsa sebōpi. Ka lebaka la boholo ba eona bo batlang bo sa fetohe pele le ka morao ho sintering, e ka sebetsoa ka sebopeho leha e le sefe le boholo ka mor'a ho bōptjoa. Bahlahisi ba Kiln ba ka iketsetsa libopeho tse fapaneng le litlhaloso tsa likarolo ho latela meralo e fapaneng ea sebōpi le litlhoko tsa tlhahiso, ho fihlela litlhoko tsa tlhahiso ea lihlahisoa tse kholo le tse rarahaneng, tseo ho leng thata hore lisebelisoa tse ling li ka li fihlela.
Mohala o matla oa ts'ireletso ea sistimi ea desulfurization
Lebaleng la ts'ireletso ea tikoloho joalo ka desulfurization ea semela sa motlakase, li-ceramics tsa sintered silicon carbide le tsona li bapala karolo ea bohlokoa, e bonts'itsoeng haholo ke karolo ea bohlokoa ea li-nozzles tsa desulfurization. Khase ea flue e tsoang litsing tsa motlakase e na le lintho tse ngata tse silafatsang tse kang sulfur dioxide, 'me li-nozzles tsa desulfurization ke lisebelisoa tsa bohlokoa bakeng sa ho tlosa litšila tsena.
The reaction sintered silicon carbide desulfurization nozzle e na le thepa e ntle joalo ka matla a phahameng, boima bo phahameng, khanyetso e matla ea kutu, khanyetso ea ho roala le ho hanyetsa mocheso o phahameng. E na le bophelo bo sa tloaelehang ba tšebeletso tlas'a maemo a thata, a ke keng a bapisoa le thepa e tloaelehileng. Mefuta e sebelisoang hangata ea li-nozzles tsa desulfurization e kenyelletsa li-spiral nozzles le vortex nozzles, tse nang le meralo e fapaneng le melao-motheo ea ts'ebetso, empa e khona ho etsa atomize desulfurizer le ho ikopanya le eona ka botlalo le khase ea flue, ka hona ho fihlela phello e ntle ea desulfurization.
Ka moralo o ikhethang oa sebopeho, sekoti sa spiral se etsa hore mokelikeli o karolong e ka ntle e otle holim'a spiral ka lehlakoreng le itseng holim'a nozzle, e fetola tsela ea ho fafatsa 'me e siea molomo, e etsa sebaka se tiileng sa moholi, se ka fanang ka mefuta e fapaneng ea li-angles tsa spray,' me se ntse se e-na le bokhoni bo phahameng ba ho monya tlas'a khatello e tlaase ka ho fetisisa. Nozzle ea vortex e lumella slurry ho kena ka phaposing e sisinyehang ea nozzle ho tloha ka lehlakoreng le tangent, ebe e tsoa ho orifice ka likhutlo tse nepahetseng ho ea tseleng e kenang. Spray e nyenyane ebile e tšoana, 'me mocha oa vortex o moholo, oo ho seng bonolo ho o thibela.
Bakeng sa likarolo tse ikhethileng tsa litsamaiso tsa desulfurization, reaction sintered silicon carbide e ka etsa sebopeho se nepahetseng ka ho fetesisa sa nozzle, boholo, le litšoaneleho tsa ho fafatsa ho latela lits'ebetso tse fapaneng tsa desulfurization, likhahla tsa phallo ea khase ea flue, likhakanyo le likarolo tse ling, ho netefatsa ts'ebetso e tsitsitseng le e tsitsitseng ea sistimi ea desulfurization le ho kopana le litlhoko tse thata tsa tikoloho.
Li-reaction sintered silicon carbide ceramics li bapala karolo e ke keng ea nkeloa sebaka mafapheng a setso a indasteri joalo ka li-kilns le lits'ebetso tsa desulfurization ka lebaka la thepa ea tsona e ikhethang le melemo eo motho a ka e khethang. Ba fana ka tiisetso e tiileng bakeng sa ts'ebetso e sebetsang hantle, e tsitsitseng, le tikoloho ea tlhahiso ea indasteri le ho kenya ts'usumetso e matla ntlafatsong ea thekenoloji le nts'etsopele ea liindasteri tsa setso.
