Kwihlabathi elikhulu lemveliso yezoshishino, ezininzi izixhumanisi eziphambili azikwazi ukwenza ngaphandle kokuxhaswa kwezinto eziphezulu zokusebenza. Namhlanje, siza kwazisa imathiriyeli edlala indima ebalulekileyo kumashishini emveli anje ngeekhilni kunye neenkqubo ze-desulfurization -reaction sintered silicon carbide ceramics.
Yintoni i-silicon carbide ceramic?
I-Silicon carbide ceramic yimathiriyeli ye-ceramic ephezulu eyenziwe ngesilicon kunye nekhabhoni. Ayisiyo i-ceramic eqhelekileyo, kodwa "i-metamaterial" eneempawu ezininzi ezintle. Ineempawu zamandla obushushu obuphezulu, ukumelana nokunxiba kakuhle, i-coefficient ephantsi yokwandiswa kwe-thermal, ubunzima obuphezulu, kunye nokumelana nokugqwala kweekhemikhali, ezenza ukuba zivelele phakathi kwezinto ezininzi.
I-Reaction sintered silicon carbide ceramics luhlobo olukhethekileyo lwe-silicon carbide ceramics, kwaye inkqubo yabo yokulungiselela ihluke kakhulu - okokuqala, amasuntswana amahle e-alpha SiC kunye nezongezo zicinezelwe kumzimba oluhlaza, emva koko zidibene ne-silicon yolwelo kwiqondo lokushisa eliphezulu. Ngeli xesha, i-carbon kwi-blank ithatha i-chemical reaction emangalisayo kunye ne-Si efakwe ngaphakathi, ivelisa i-β - i-SiC kwaye idibanise ngokuqinileyo kunye ne-α - SiC. Kwangelo xesha, i-silicon yasimahla igcwalisa iipores, ekugqibeleni ifumana imathiriyeli exineneyo yeceramic.
Ilitye lembombo eziko
Ukusabela kwi-rection sintering ye-silicon carbide ceramics yindima ebalulekileyo kwaye ibalulekileyo kwiikhilni ezahlukeneyo zobushushu obuphezulu. Umzekelo, kwiikhilni ze-ceramic zokuvelisa ezifana ne-roller kilns, i-tunnel kilns, i-shuttle kilns, njl., Yenziwe ibe zizinto eziphambili ezifana nemikhono ye-nozzle, i-crossbeam rollers, kunye nemibhobho yomoya ebandayo.
Umkhono we-flame nozzle unokulawula ngokufanelekileyo ibhalansi yobushushu ngaphakathi kwe-oven. Ineempawu zamandla obushushu obuphezulu, ukumelana ne-oxidation, ukumelana nokunxiba, kunye nokuchasana nokupholisa ngokukhawuleza kunye nokufudumeza. Ayiyi kuphuka okanye ikhubazeke emva kokusetyenziswa kwexesha elide lobushushu obuphezulu, iqinisekisa indawo yobushushu obuzinzileyo kwiziko. Kubalulekile ukudubula iimveliso ze-ceramic ezikumgangatho ophezulu.
Iirola ze-crossbeam kunye ne-cold air ducts ngokulandelanayo zithwala uxanduva olubalulekileyo lokuxhasa kunye nomoya. I-roller ye-crossbeam ineempawu zokuzinza kakuhle kwe-thermal, ukuxhathisa i-oxidation, kunye nokumelana nobushushu obuphezulu be-creep. Akulula ukuguqula kunye nokugoba emva kokusetyenziswa kwexesha elide kumaqondo okushisa aphezulu, ukuqinisekisa ukuzinza kwesakhiwo sangaphakathi sesibane kunye nokuthuthwa kwezinto eziphathekayo. Umbhobho womoya obandayo unoxanduva lokulawula ukuhamba kwegesi kunye nokuhanjiswa kweqondo lokushisa ngaphakathi kwe-kiln, ukuqinisekisa ukusebenza okuqhelekileyo kwesithando.
Ngokwembono yamacandelo alungelelanisiweyo, i-react sintered silicon carbide ineengenelo ezicacileyo ekuvelisweni kwezixhobo ze-kiln. Ngenxa yobukhulu bayo obuphantse bungakhange butshintshwe ngaphambi nasemva kokucwiliswa, inokucutshungulwa kuyo nayiphi na imilo kunye nobukhulu emva kokubumba. Abavelisi beKiln banokwenza ngokwezifiso iimilo ezahlukeneyo kunye neenkcukacha zamacandelo ngokweendlela ezahlukeneyo zoyilo kunye neemfuno zemveliso, ukuhlangabezana neemfuno zemveliso yeemveliso ezinkulu nezintsonkothileyo, ekunzima ukuba ezinye izinto zifezekiswe.
Umgca wokukhusela oqinileyo wenkqubo ye-desulfurization
Kwinkalo yokhuseleko lwendalo esingqongileyo efana ne-desulfurization yeplanti yamandla, i-reaction sintered silicon carbide ceramics nayo idlala indima ephambili, ibonakaliswa ikakhulu kwicandelo eliphambili lemilomo ye-desulfurization. Irhasi yeflue ephuma kwizityalo zamandla iqulethe isixa esikhulu songcoliseko olufana nesulfure dioxide, kunye nemilomo ye-desulfurization zizixhobo ezibalulekileyo zokususa ezi ngcoliseko.
Impendulo ye-sintered silicon carbide desulfurization nozzle ineepropathi ezigqwesileyo ezinje ngokuqina okuphezulu, ukuqina okuphezulu, ukuxhathisa okuqinileyo kwe-corrosion, ukumelana nokunxiba, kunye nokumelana nobushushu obuphezulu. Inobomi benkonzo obungaqhelekanga phantsi kweemeko ezinzima, ezingenakuqhathaniswa nezinto eziqhelekileyo. Iindidi ezisetyenziswa ngokuqhelekileyo zemilomo ye-desulfurization ziquka imilomo ye-spiral kunye ne-vortex nozzles, ezinoyilo olwahlukileyo kunye nemigaqo yokusebenza, kodwa zinokusebenza ngokufanelekileyo i-atomize i-desulfurizer kwaye iqhagamshelane nayo ngokupheleleyo negesi yombane, ngaloo ndlela ifezekisa isiphumo esihle se-desulfurization.
Ngoyilo olulodwa lolwakhiwo, umbhobho ojikelezayo wenza ukuba ulwelo olukumaleko wangaphandle lubethe umphezulu ojikelezayo kwi-engile ethile emlonyeni, lutshintshe indlela yokutshiza kwaye luwushiye umlomo, lwenza intsimi yenkungu eyomeleleyo, enokubonelela ngee-engile zokutshiza, kwaye isenokusebenza okuphezulu kokufunxa phantsi kolona xinzelelo luphantsi. Umbhobho we-vortex uvumela uludaka ukuba lungene kwigumbi lokujikeleza lombhobho ukusuka kwicala le-tangent, kwaye likhuphe ukusuka kwi-orifice kwii-engile ezichanekileyo ukuya kwicala lokungena. I-spray incinci kwaye ifanayo, kwaye i-vortex channel inkulu, akulula ukuyivimba.
Kwiindawo ezilungiselelwe iinkqubo ze-desulfurization, i-action sintered silicon carbide inokwenza eyona milo ye-nozzle ifanelekileyo, ubungakanani, kunye neempawu zokutshiza ngokweenkqubo ezahlukeneyo ze-desulfurization, amazinga okuhamba kwerhasi ye-flue, ugxininiso, kunye nezinye iiparameters, ukuqinisekisa ukusebenza ngokufanelekileyo kunye nokuzinza kwenkqubo ye-desulfurization kunye nokuhlangabezana neemfuno ezingqongqo zokusingqongileyo.
Iiseramikhi ze-silicon carbide zokusabela zidlala indima engenakuphinda zithathelwe indawo kwiindawo zoshishino zemveli ezifana neekhilni kunye neenkqubo ze-desulfurization ngenxa yeepropathi zazo ezizodwa kunye noncedo olunokwenzeka. Babonelela ngesiqinisekiso esiluqilima sokusebenza okusebenzayo, okuzinzileyo, kunye nokusingqongileyo kwimveliso yamashishini kwaye bafaka impembelelo eyomeleleyo kuphuculo lwetekhnoloji kunye nophuhliso lwamashishini emveli.
