Kwindawo yemfazwe yoKhuselo lweBlue Sky, kukho 'indoda ephambili' engaziwayo ekhusela impilo yethu yokuphefumla ngokuzolileyo - ayisiyonto inkulu yokufunxa okanye inkqubo yokulawula enzima, kodwa yi-umlomo wokukhupha i-flue gas desulfurization (umlomo wokucoca i-FGD)enobubanzi obuziimilimitha ezimbalwa kuphela – le nxalenye incinci ingabonakaliyo yeyona nto iphambili ekusebenzeni kakuhle kwenkqubo yonke yokukhupha i-sulfurization.
Njenge "mqala" wenkqubo yokususa i-sulfurization, umlomo kufuneka umelane "novavanyo oluphindwe kathathu" lobushushu obuphezulu, ukugqwala okunamandla, kunye nokuguguleka okuphezulu. Izinto zesinyithi zemveli zihlala zifumana iingxaki ezifana nokwandiswa kobukhulu beembobo kunye nokungaphumeleli kwe-atomization emva kweenyanga ezininzi zokukhukuliseka yi-asidi slurry; Nangona iiplastiki zobunjineli zimelana nokugqwala, kunzima ukumelana nobushushu obuphezulu obuqhubekayo. Okwangoku, impumelelo enkulu evela kwisayensi yezinto zanamhlanje - i-reaction sintered silicon carbide ceramics, kukubhala ngokutsha imigangatho yoshishino.
Olu hlobo lutsha lwe-ceramic, olwaziwa ngokuba yi-"igolide emnyama yezimboni," lubonisa iimpawu ezimangalisayo kwinqanaba le-microscopic: izigidi zeekristale ze-silicon carbide zenza inethiwekhi exineneyo ngeenkqubo ezikhethekileyo zokusila, zenza ubulukhuni obufana nedayimani. Xa i-desulfurization slurry equlethe amasuntswana e-gypsum igutyungelwa ngoxinzelelo oluphezulu kunye nesantya, izinga layo lokuguguleka liphantsi kakhulu kunelentsimbi eqhelekileyo. Okubaluleke ngakumbi, inamandla "aphezulu" endalo okumelana nokugqwala kwe-asidi kunye ne-alkali, kwaye inokugcina umzimba wayo ungatshabalaliyo naphantsi kweemeko zokuguquguquka okukhulu kwe-pH.
Ngokuphathelele ukuzinza, le nto ibonisa ubomi obumangalisayo benkonzo. Ukuphambuka kwe-atomization angle yale nozzle yezinto kusalawulwa kuluhlu oluncinci kakhulu emva kweminyaka eliqela, kwaye olu buchule bokugcina ngokuchanekileyo buyandisa umjikelo wokugcinwa kwezixhobo izihlandlo ezininzi.
Kubathengi abafuna ukusebenzisa iinkqubo zokususa i-sulfurization, ukukhetha i-silicon carbide nozzles kufana nokuthenga "i-inshurensi yobomi bonke" yezixhobo. Akunciphisi nje kuphela iindleko zokutshintshwa kwezixhobo ezingasetyenziswanga, kodwa okubaluleke ngakumbi, kuqinisekisa uzinzo oluqhubekayo lokusebenza kakuhle kwe-desulfurization - okunxulumene ngokuthe ngqo nemigangatho yokhuseleko lokusingqongileyo kunye nemveliso ezinzileyo yamashishini.
Izixhobo zombhobho ezenziwe ngetekhnoloji yoomatshini bokuchwetheza ngokuchanekileyo ezinelungelo elilodwa lomenzi zivavanywa izihlandlo ezininzi, kubandakanya novavanyo lwe-atomization, ngaphambi kokuba ziphume kumzi-mveliso ukuqinisekisa ukuba iingenelo zezinto ezisetyenzisiweyo ziguqulwa zibe ziingenelo ezibonakalayo zokusingqongileyo.
Kuhambo olutsha olukhokelwa yinjongo "yekhabhoni ephindwe kabini", ubugcisa obutsha bufaka amandla ahlala ixesha elide kwizixhobo zokukhusela okusingqongileyo. Ukusetyenziswa ngokubanzi kwe-reaction sintered silicon carbide ceramic nozzles yingcaciso ecacileyo yotshintsho lwezinto ezisetyenziswayo olunika amandla ukuveliswa kwezityalo eziluhlaza. Xa sijonga phezulu esibhakabhakeni esiluhlaza okwesibhakabhaka, sinokucinga ngaba "bagcini be-ceramic" abafihle izakhono zabo nodumo lwabo - bakhusela ubunyulu bamawaka eemitha ngokunyamezela kwinqanaba le-millimeter.
