Kwinkqubo yokucoca igesi yolwelo lwemizi-mveliso, inkqubo yokukhupha i-sulfurization idlala indima ebalulekileyo, kwaye enye into ebonakala ingabalulekanga - umlomo, ichaphazela ngokuthe ngqo ukusebenza kakuhle kunye nokuzinza kwenkqubo yonke. Kwiminyaka yakutshanje,ii-nozzles ze-desulfurization ezenziwe ngezinto ze-silicon carbideziye kancinci kancinci zaba yeyona nto ithandwayo kushishino. Namhlanje, masithethe ngeempawu zazo ezikhethekileyo.
Yintoni i-silicon carbide?
I-silicon carbide (i-SiC) yikhompawundi eyenziwe yi-silicon kunye ne-carbon, enobunzima obuphezulu kakhulu kunye nokumelana nobushushu obuphezulu kunye nokugqwala. Ubunzima bayo be-Mohs bufikelela kwi-9.5, bulandela idayimani kuphela, oko kuthetha ukuba ayigugi kakhulu. Kwangaxeshanye, i-silicon carbide inokugcina uzinzo kwiindawo ezinobushushu obuphezulu obungaphezulu kwe-1350 ℃, nto leyo eyinika ithuba lendalo kwiimeko ezinzima zokusebenza.
Kutheni ukhetha i-silicon carbide njengomlomo wokukhupha i-sulfurization?
Indawo yokusebenza yeempumlo ze-desulfurization ingachazwa njenge "ngqongqo":
-Ukuvezwa ixesha elide kwi-slurry ebolileyo ene-asidi kunye ne-alkaline
-Ukucoca ulwelo ngesantya esiphezulu
-Ukuguquguquka okukhulu kobushushu
-Ingaba namasuntswana aqinileyo
Iimpumlo zesinyithi zemveli zidla ngokugqwala kwaye ziguge, ngelixa iimpumlo zeplastiki zingenalo ukumelana nobushushu. Impumlo ye-silicon carbide ilungisa ngokuchanekileyo ezi ntsilelo, kwaye izibonelelo zayo eziphambili ziquka:
1. Ukumelana nokugqwala okunamandla kakhulu
I-silicon carbide inokumelana kakuhle ne-corrosive media efana ne-asidi, i-alkali, kunye netyuwa, kwaye ubomi bayo budlula kakhulu obo be-nozzles zesinyithi nezeplastiki.
2. Ukumelana nokuguguleka okugqwesileyo
Nokuba i-slurry iqulethe amasuntswana aqinileyo, i-silicon carbide nozzle inokugcina ukusebenza okuzinzileyo kokutshiza ixesha elide kwaye ayitshintshi lula kwi-engile yokutshiza ngenxa yokuguguleka.
3. Ukusebenza kokumelana nobushushu obuphezulu
Kwiindawo ezinegesi yolwelo olushushu kakhulu, iimpumlo ze-silicon carbide aziyi kujika okanye zithambise, nto leyo eqinisekisa ukuba imiphumo yokutshiza izinzile.
4. Ukuqhuba kakuhle kobushushu
Inceda umlomo ukuba ukhuphe ubushushu ngokukhawuleza kwaye unciphise umonakalo obangelwa kuxinzelelo lobushushu.
Umgaqo wokusebenza kwe-silicon carbide nozzle
I-silicon carbide desulfurization nozzle i-atomize i-desulfurization slurry (ngokuqhelekileyo i-limestone slurry) ibe ngamaconsi amancinci, adibana ngokupheleleyo negesi ye-flue, nto leyo ebangela ukuba izinto ze-alkaline kwi-slurry zisabele ngokwekhemikhali kwi-sulfur dioxide kwigesi ye-flue, ngaloo ndlela kufezekiswa injongo ye-desulfurization.
Uyilo kunye nezinto ezisetyenziswa kwi-nozzle zichaphazela ngokuthe ngqo isiphumo se-atomization:
-Okukhona amasuntswana e-atomized ecolekile, kokukhona indawo yoqhagamshelwano inkulu, kwaye kokukhona ukusebenza kakuhle kwe-desulfurization kuphezulu
-Izinto ze-silicon carbide ziqinisekisa uzinzo lwexesha elide lwe-nozzle aperture, zithintela ukwehla kwesiphumo se-atomization ngenxa yokuguguleka nokukrazuka.
Iimeko zesicelo
Ii-nozzles ze-silicon carbide desulfurization zisetyenziswa kakhulu kwezi:
-Isikhululo samandla esishushu
-Isityalo sentsimbi
-Isityalo sokutshisa inkunkuma
-Amanye amacandelo emizi-mveliso afuna ukususwa kwegesi yolwelo
Iingcebiso zokugcinwa kwemihla ngemihla
Nangona imilomo ye-silicon carbide iqinile, uhlolo nokugcinwa rhoqo kusabalulekile:
-Jonga rhoqo ukuba umlomo uvaliwe okanye unxilile
-Gcina ukusebenza kakuhle kwenkqubo yokucoca uludaka
-Tshintsha umlomo ngokukhawuleza xa ufumanisa ukuba ukusebenza kwawo kuyehla
isishwankathelo
Nangona umlomo we-silicon carbide desulfurization uyinxalenye encinci kwinkqubo ye-desulfurization, udlala indima ebalulekileyo ekuphuculeni ukusebenza kakuhle kwe-desulfurization kunye nokunciphisa iindleko zokusebenza. Ube lukhetho olukhethwayo kumashishini amaninzi ngenxa yokumelana kwayo okuhle nokugqwala, ukumelana nokuguguleka, kunye nokumelana nobushushu obuphezulu.
Ukukhetha izixhobo zomlomo ezifanelekileyo kunye noyilo akunakuphucula nje kuphela izalathisi zokusingqongileyo, kodwa kunokuzisa neenzuzo zoqoqosho zexesha elide kwishishini. Kwimfuno yokusingqongileyo yanamhlanje engqongqo ngakumbi, imilomo yokukhupha i-silicon carbide desulfurization ikhusela isibhakabhaka sethu esiluhlaza okwesibhakabhaka ngokuthula.
