Kwihlabathi elikhulu lemveliso yemizi-mveliso, amakhonkco amaninzi abalulekileyo awanakukwazi ukwenza ngaphandle kwenkxaso yezinto ezisebenza kakuhle. Namhlanje, siza kwazisa izinto ezidlala indima ebalulekileyo kumashishini emveli afana nee-ovens kunye neenkqubo zokususa i-sulfurization -iiseramikhi ze-silicon carbide ezixutywe ne-reaction.
Yintoni i-silicon carbide ceramic?
I-silicon carbide ceramic yinto eyenziwe nge-ceramic ephucukileyo eyenziwe nge-silicon ne-carbon. Ayisiyo i-ceramic eqhelekileyo, kodwa "yi-metamaterial" eneempawu ezininzi ezintle. Ineempawu zokuba namandla aphezulu obushushu, ukumelana nokuguguleka okuhle, i-coefficient ephantsi yokwanda kobushushu, ubunzima obuphezulu, kunye nokumelana nokugqwala ngamakhemikhali, okwenza ukuba ibonakale phakathi kwezinto ezininzi.
Iiceramics zesilicon carbide ezisebenzisa i-reaction sintered luhlobo olukhethekileyo lweeceramics zesilicon carbide, kwaye inkqubo yazo yokulungiselela ikhethekile kakhulu - okokuqala, amasuntswana amancinci e-alpha SiC kunye nezongezo zicinezelwa emzimbeni oluhlaza, emva koko zidibene nesilicon engamanzi kubushushu obuphezulu. Kule ndawo, ikhabhoni engenanto ifumana impendulo emangalisayo yeekhemikhali kunye ne-Si engenileyo, ivelisa i-β - SiC kwaye ibotshelelwe ngokuqinileyo ne-α - SiC. Kwangaxeshanye, isilicon ekhululekileyo izalisa ii-pores, ekugqibeleni ifumana izinto zeceramic ezixineneyo kakhulu.
Ilitye lembombo elise-oven
Ukusila kwee-silicon carbide ceramics yindima ebalulekileyo nebalulekileyo kwii-oven ezahlukeneyo ezinobushushu obuphezulu. Umzekelo, kwii-oven zemveliso ye-ceramic ezifana nee-roller kilns, ii-tunnel kilns, ii-shuttle kilns, njl.njl., zenziwe zibe zizinto ezibalulekileyo ezifana nee-nozzle sleeves, ii-crossbeam rollers, kunye nee-cold air pipes.
Isingxobo somlomo welangatye sinokulawula ngokufanelekileyo ibhalansi yobushushu ngaphakathi kwi-oven. Sineempawu zokuba namandla obushushu aphezulu, ukumelana ne-oxidation, ukumelana nokuguguleka, kunye nokumelana nokuphola ngokukhawuleza kunye nokufudumeza. Asiyi kwaphuka okanye siguquguquke emva kokusetyenziswa ixesha elide kobushushu obuphezulu, ukuqinisekisa imeko-bume yobushushu obuzinzileyo kwi-oven. Kubalulekile ekutshiseni iimveliso zeseramikhi ezikumgangatho ophezulu.
Iirola ezinqamlezileyo kunye neepayipi zomoya obandayo ngokulandelelanayo zinoxanduva olubalulekileyo lokuxhasa kunye nokuphefumla. Irola ezinqamlezileyo zineempawu zokuzinza okuhle kobushushu, ukumelana ne-oxidation, kunye nokumelana nokuqhekeka kobushushu obuphezulu. Akulula ukuyiguqula nokugoba emva kokusetyenziswa ixesha elide kumaqondo obushushu aphezulu, ukuqinisekisa uzinzo lwesakhiwo sangaphakathi se-oven kunye nokuthuthwa kwezinto ezithambileyo. Ipayipi yomoya obandayo inoxanduva lokulawula ukuhamba kwegesi kunye nokusasazwa kobushushu ngaphakathi kwi-oven, ukuqinisekisa ukusebenza okuqhelekileyo kwe-oven.
Ngokwembono yeendawo ezenzelwe wena, i-reaction sintered silicon carbide ineengenelo ezicacileyo ekuvelisweni kweendawo ze-oven. Ngenxa yobukhulu bayo obungatshintshiyo ngaphambi nasemva kokuyitshisa, ingacutshungulwa ibe yiyo nayiphi na imilo kunye nobukhulu emva kokuyila. Abavelisi be-kiln banokwenza ngokwezifiso iimilo ezahlukeneyo kunye neenkcukacha zeendawo ngokweemfuno ze-oven ezahlukeneyo kunye neemfuno zemveliso, ukuhlangabezana neemfuno zemveliso yeemveliso ezinkulu nezintsonkothileyo, okunzima ukuba ezinye izinto zifezekiswe.
Umgca wokhuselo oqinileyo wenkqubo yokukhupha i-sulfurization
Kwicandelo lokhuseleko lokusingqongileyo olufana nokususwa kwesulfurization yezityalo zamandla, iiseramikhi zesilicon carbide ezisebenzisa i-reaction sintered nazo zidlala indima ebalulekileyo, ebonakala kakhulu kwicandelo eliphambili leempumlo ze-desulfurization. Igesi yeflue ekhutshwa kwizityalo zamandla iqulethe inani elikhulu leempumlo ezifana ne-sulfur dioxide, kwaye iimpumlo ze-desulfurization zizixhobo ezibalulekileyo zokususa ezi mpumlo.
I-nozzle ye-silicon carbide desulfurization ene-reaction ineempawu ezintle kakhulu ezifana namandla aphezulu, ubulukhuni obuphezulu, ukumelana nokugqwala okunamandla, ukumelana nokuguguleka, kunye nokumelana nobushushu obuphezulu. Inomsebenzi ongaqhelekanga phantsi kweemeko ezinzima, okungenakuthelekiswa nezinto eziqhelekileyo. Iindidi ze-nozzle ze-desulfurization ezisetyenziswa rhoqo ziquka i-spiral nozzles kunye ne-vortex nozzles, ezineedizayini ezahlukeneyo kunye nemigaqo yokusebenza, kodwa zinokusebenzisa i-atomizer ye-desulfurizer ngokufanelekileyo kwaye zidibanise ngokupheleleyo negesi ye-flue, ngaloo ndlela zifezekisa isiphumo esihle se-desulfurization.
Ngenxa yoyilo olukhethekileyo lwesakhiwo, i-spiral nozzle yenza ulwelo olukwindawo engaphandle lubethe umphezulu we-spiral kwi-engile ethile kwi-nozzle, lutshintshe indlela yokutshiza kwaye lushiye i-nozzle, lwenze intsimi yenkungu eqinileyo, enokubonelela ngee-engile ezahlukeneyo zokutshiza, kwaye isenokusebenza kakuhle kokufunxa phantsi koxinzelelo oluphantsi. I-vortex nozzle ivumela i-slurry ukuba ingene kwigumbi elijikelezayo le-nozzle ukusuka kwicala eli-tangent, ize ikhuphe kwi-orifice kwii-engile zasekunene ukuya kwicala lokungena. I-spray incinci kwaye iyafana, kwaye i-vortex channel inkulu, ekulula ukuyivimba.
Kwiindawo ezenzelwe wena zeenkqubo zokususa i-sulfurization, i-silicon carbide exutywe ne-reaction ingenza ngokwezifiso imo ye-nozzle, ubungakanani, kunye neempawu zokutshiza ezifanelekileyo ngokweenkqubo ezahlukeneyo zokususa i-sulfurization, amazinga okuhamba kwegesi ye-flue, ubuninzi, kunye nezinye iiparameter, ukuqinisekisa ukusebenza okusebenzayo nokuzinzileyo kwenkqubo yokususa i-sulfurization kunye nokuhlangabezana neemfuno ezingqongqo zokusingqongileyo.
Iiseramikhi ze-silicon carbide ezisebenzisa i-reaction sintered zidlala indima engenakutshintshwa kwiinkalo zoshishino zemveli ezifana nee-ovens kunye neenkqubo zokususa i-sulfurization ngenxa yeempawu zazo ezizodwa kunye neenzuzo ezinokwenziwa ngokwezifiso. Zibonelela ngesiqinisekiso esiqinileyo sokusebenza ngokufanelekileyo, okuzinzileyo, kunye nokusingqongileyo kwemveliso yezimboni kwaye zifaka impembelelo enamandla ekuphuculweni kwetekhnoloji kunye nophuhliso lwemizi-mveliso yemveli.
