Kwicandelo lonyango lwegesi yolwelo lwemizi-mveliso, inkqubo yokucoca i-sulfur ifana "nesicoci" esikhusela isibhakabhaka esiluhlaza kunye namafu amhlophe, kwaye umlomo wokucoca i-sulfur "yindibaniselwano echanekileyo" yale nkqubo. Kwiminyaka yakutshanje,ii-nozzles ze-desulfurization ezenziwe ngezinto ze-silicon carbideziye kancinci kancinci zaba lukhetho oludumileyo lokuphucula izixhobo zokukhusela okusingqongileyo ngenxa yeenzuzo zazo zokusebenza ezikhethekileyo. Ziziphi iimpawu ezibalaseleyo zale nozzle intsha yezinto ezibonakalayo? Siza kukusa ukuze uhlolisise inyaniso.
1, 'Iqhawe lesinyithi' elingagugiyo ngokwendalo
I-silicon carbide yaziwa ngokuba “lizinyo lemizi-mveliso” kwaye ubulukhuni bayo bulandela idayimani kuphela. I-nozzle eyenziwe ngayo inokugcina umphezulu uthambile kwaye umtsha nokuba ikwi-lime slurry ekhawulezayo. Olu phawu oluqhelekileyo lokumelana nokuguguleka lwandisa ubomi be-nozzle ixesha elide kunezixhobo zemveli, nto leyo enciphisa kakhulu ixesha lokungasebenzi kunye nokutshintshwa, nto leyo eyenza ukuba ifaneleke ngakumbi kwiimeko ezifana nokuveliswa kombane oshushu kunye nokunyibilikiswa kwentsimbi okufuna ukusebenza ixesha elide.
2, Ingcali enganyangekiyo ngumhlwa enokumelana ne-asidi kunye ne-alkali
Ngexesha lenkqubo yokususa i-sulfurization, i-nozzle ayimelani nje kuphela nokusingqongileyo kodaka kunye nokuguquguquka okukhulu kwe-pH, kodwa ikwajongene nokukhukuliseka kweegesi ezine-sulfur ezinobushushu obuphezulu. Izinto ze-silicon carbide zinamandla kakhulu ekungeneni kweekhemikhali, azisabelani ne-acidic okanye i-alkaline media, kwaye azidli ziikhompawundi ezine-sulfur. Olu phawu "olungenabungozi" luqinisekisa ukusebenza okuzinzileyo kwe-nozzle phantsi kweemeko zokusebenza ezinzima.
3, uMnu. Zola phantsi kobushushu obuphezulu
Ukugcina uzinzo kwisakhiwo nokuba kumaqondo obushushu aphezulu angama-1350 ℃ – ubuchule obukhethekileyo be-silicon carbide buvumela ii-nozzles ze-desulfurization ukuba ziphathe ubushushu begesi echithwa yi-boiler flue ngokulula. Ngokungafaniyo nengxaki yokuguquguquka kobushushu bezinto zesinyithi kunye nokuchaphazeleka kubushushu kunye nokuqhekeka kwezinto ze-ceramic, ii-nozzles ze-silicon carbide zinokugcina ii-engile ezichanekileyo ze-atomization ngexesha lokubanda okukhulu kunye nokutshintshana okushushu.
4, 'umculi we-atomization' oyilwe ngononophelo
Ii-nozzles ze-silicon carbide zanamhlanje zamkela isakhiwo esicwangcisiweyo, esinokwenza i-desulfurization slurry ibe ngamaconsi amancinci ngokubala ngokuchanekileyo ukugoba kodonga lwangaphakathi. Esi siphumo se-atomization siyandisa kakhulu indawo yoqhagamshelwano phakathi kwe-slurry kunye negesi ye-flue, nto leyo ephucula kakhulu ukusebenza kwe-desulfurization.
5, 'Uvulindlela Wendalo' Wemveliso Eluhlaza
Yonke inkqubo yokuvelisa ii-nozzles ze-silicon carbide, ukusuka ekulungisweni kwezinto eziluhlaza ukuya ekutshisweni kwemveliso egqityiweyo, ayivelisi inkunkuma enobungozi. Ubomi bayo obude kakhulu benkonzo bunciphisa ukusetyenziswa kwezixhobo ezibangelwa kukutshintshwa kwezixhobo, nto leyo efezekisa ukhuseleko lokusingqongileyo kulo lonke ixesha lobomi ukususela kwimveliso ukuya ekusetyenzisweni.
Njengokwenziwa kwe-crystallization yetekhnoloji yanamhlanje yokukhusela okusingqongileyo kunye nesayensi yezinto, ii-nozzles ze-silicon carbide desulfurization zibonelela ngezisombululo ezithembekileyo ngakumbi zonyango lwegesi ye-flue yemizi-mveliso. Siyaqhubeka nokwandisa ulwazi lwethu kwicandelo le-ceramics ezikhethekileyo, sisebenzisa uyilo lokuguqulwa kwezinto kunye nokwenza ngcono i-fluid dynamics ukwenza i-nozzle nganye ibe ngumqobo oqinileyo wokukhusela isibhakabhaka esiluhlaza. Phantsi kwesikhokelo se-"dual carbon" target, olu hlobo lutsha lwecandelo elinobuhlobo nokusingqongileyo elilinganisela ukusebenza kakuhle kunye nokuqina ngokungathandabuzekiyo luya kufaka amandla obuchwephesha kutshintsho oluhlaza lwamashishini amaninzi.
