Kwimveliso yemizi-mveliso, ukususwa kwesulfurization ngumsebenzi obalulekileyo kwindalo esingqongileyo onxulumene nokuphuculwa komgangatho womoya kunye nophuhliso oluzinzileyo. Kwinkqubo yokususwa kwesulfurization, umlomo wokususwa kwesulfurization udlala indima ebalulekileyo, kwaye ukusebenza kwawo kuchaphazela ngokuthe ngqo isiphumo sokususwa kwesulfurization. Namhlanje, siza kutyhila isigqubuthelo esingaqondakaliyoumlomo wokucoca i-silicon carbide ceramickwaye ubone ukuba zeziphi iimpawu ezikhethekileyo ezinazo.
Impumlo yokususa isalfurization: "isixhobo sokudubula esiphambili" senkqubo yokususa isalfurization
I-desulfurization nozzle yinxalenye ebalulekileyo yenkqubo ye-desulfurization. Umsebenzi wayo ophambili kukufafaza i-desulfurizer ngokulinganayo (njenge-limestone slurry) kwi-flue gas, okuvumela i-desulfurizer ukuba iqhagamshelane ngokupheleleyo kwaye isabela kwiigesi ezinobungozi ezifana ne-sulfur dioxide kwi-flue gas, ngaloo ndlela ifezekisa injongo yokususa iigesi ezinobungozi kunye nokucoca i-flue gas. Kunokuthiwa i-desulfurization nozzle ifana "ne-shooter" echanekileyo, kwaye isiphumo sayo "sokudubula" simisela impumelelo okanye ukungaphumeleli kwedabi le-desulfurization.
Iiceramics ze-silicon carbide: "indlu enamandla" yendalo ekunyibilikiseni i-sulfurization
I-silicon carbide ceramic luhlobo olutsha lwezinto ze-ceramic ezineempawu ezininzi ezintle, nto leyo eyenza ukuba ibe lolona khetho lufanelekileyo lokwenza i-desulfurization nozzles:
1. Ubunzima obuphezulu kunye nokumelana nokuguguleka okunamandla: Ngexesha lenkqubo yokususa i-sulfurization, umlomo kufuneka umelane nokuhamba kwe-desulfurizer ngesantya esiphezulu kunye nokuguguleka kwamasuntswana kwigesi ye-flue ixesha elide. Izinto eziqhelekileyo ziguguleka lula, nto leyo ebangela ukuba ubomi be-nozzle bufutshane kwaye kunciphe ukusebenza. Ubunzima be-silicon carbide ceramics buphezulu kakhulu, bulandela kuphela izinto ezimbalwa ezifana nedayimani kunye ne-cubic boron nitride, kwaye ukumelana nokuguguleka kuphezulu ngokuphindwe kaninzi kunokwesinyithi esiqhelekileyo kunye nezinto ze-ceramic. Oku kwenza ukuba umlomo we-silicon carbide ceramic desulfurization usebenze ngokuzinzileyo ixesha elide kwiindawo zokusebenza ezinzima, nto leyo enciphisa kakhulu iindleko zokugcina kunye nokutshintsha izixhobo.
2. Ukumelana okugqwesileyo nobushushu obuphezulu: Ubushushu begesi ye-flue yemizi-mveliso buhlala buphezulu, ngakumbi kwezinye iinkqubo zoshishino ezinobushushu obuphezulu ezifana nokuveliswa kwamandla obushushu kunye nokunyibilikiswa kwentsimbi. Izixhobo eziqhelekileyo zinobuthathaka bokuthamba, ukuguqulwa, kunye nokunyibilika kubushushu obuphezulu, okwenza zingakwazi ukusebenza kakuhle. Iiseramikhi ze-silicon carbide zinokumelana okugqwesileyo nobushushu obuphezulu kwaye zinokugcina iipropati zomzimba nezikhemikhali ezizinzileyo kwiindawo ezinobushushu obuphezulu ngaphezulu kwe-1300 ℃, ukuqinisekisa ukusebenza okuthembekileyo kwee-nozzles kwigesi ye-flue enobushushu obuphezulu ngaphandle kokuchaphazela ukusebenza kakuhle kwe-desulfurization.
3. Ukumelana nokugqwala okunamandla: Uninzi lwee-desulfurizers zinomlinganiselo othile wokugqwala, kwaye igesi yeflue ikwanazo neegesi ezahlukeneyo ze-asidi kunye nokungcola, okubangela umngeni omkhulu kwizinto ze-nozzle. Iiceramics ze-silicon carbide zinozinzo oluphezulu lweekhemikhali kwaye zinokubonisa ukumelana nokugqwala okunamandla kwiindawo ezahlukeneyo ze-corrosive ezifana ne-asidi, i-alkali, ityuwa, njl.njl., zikwazi ukumelana ngempumelelo nokugqwala kweekhemikhali ngexesha lenkqubo ye-desulfurization kwaye zandise ubomi benkonzo yee-nozzle.
Umgaqo wokusebenza kunye neenzuzo ze-silicon carbide ceramic desulfurization nozzle
Xa isebenza, i-silicon carbide ceramic desulfurization nozzle isebenzisa uyilo lwayo olukhethekileyo lolwakhiwo ukutshiza i-desulfurizer kwi-flue gas ngendlela ethile yokutshiza kunye ne-engile. Iimilo eziqhelekileyo zokutshiza yi-solid cone kunye ne-hollow cone. Ezi zakhiwo zinokudibanisa ngokupheleleyo i-desulfurizer kunye ne-flue gas, zonyuse indawo yoqhagamshelwano phakathi kwazo, kwaye ngaloo ndlela ziphucule ukusebenza kakuhle kwe-desulfurization.
1. Ukusebenza kakuhle kwe-desulfurization: Ngenxa ye-silicon carbide ceramic desulfurization nozzle, i-desulfurizer inokutshizwa ngokulinganayo nangokucokisekileyo kwi-flue gas, okuvumela i-desulfurizer ukuba iqhagamshelane ngokupheleleyo neegesi ezinobungozi ezifana ne-sulfur dioxide, okukhuthaza kakhulu ukusabela kweekhemikhali kunye nokufezekisa ukusebenza okuphezulu kwe-desulfurization, okunciphisa ngempumelelo ukukhutshwa kwegesi okunobungozi.
2. Ubomi obude benkonzo: Ngenxa yokusebenza kakuhle kwee-silicon carbide ceramics ngokwazo, ii-silicon carbide ceramic desulfurization nozzles zisenokugcina ukusebenza kakuhle xa zijongene neemeko ezinzima zokusebenza ezifana nobushushu obuphezulu, ukugqwala, kunye nokuguguleka, kwaye ubomi bazo benkonzo buyandiswa kakhulu xa kuthelekiswa nee-nozzles zezinto eziqhelekileyo. Oku akunciphisi nje kuphela ixesha lokungasebenzi kwezixhobo zokulungisa, kuphucula ukusebenza kakuhle kwemveliso, kodwa kunciphisa neendleko zokusebenza zeshishini.
3. Uzinzo oluhle: Iipropati zomzimba nezekhemikhali ze-silicon carbide ceramics zizinzile, nto leyo evumela i-desulfurization nozzle ukuba igcine ukusebenza okulinganayo ngexesha lokusebenza ixesha elide ngaphandle kokuguquguquka okukhulu ngenxa yeemeko zendalo, nto leyo enika inkxaso enamandla yokusebenza okuzinzileyo kwenkqubo ye-desulfurization.
