Mwisi nini yumusaruro winganda, amahuriro menshi yingenzi ntashobora gukora adashyigikiwe nibikoresho bikora neza. Uyu munsi, tuzamenyekanisha ibikoresho bifite uruhare runini mu nganda gakondo nk'itanura na sisitemu ya desulfurizasi -reaction yacumuye silicon karbide ceramics.
Silicon carbide ceramic ni iki?
Silicon carbide ceramic nibikoresho byateye imbere bigizwe na silicon na karubone. Ntabwo ari ceramic isanzwe, ahubwo "metamaterial" ifite ibintu byinshi byiza cyane. Ifite ibiranga imbaraga zubushyuhe bwo hejuru, kwihanganira kwambara neza, coefficient nkeya yo kwagura ubushyuhe, ubukana bwinshi, hamwe no kurwanya ruswa ya chimique, bigatuma igaragara cyane mubikoresho byinshi.
Imyitwarire ya silicon carbide ceramics nubwoko bwihariye bwa silicon carbide ceramics, kandi uburyo bwo kuyitegura burihariye - icya mbere, uduce duto twa alpha SiC ninyongeramusaruro dushyirwa mumubiri wicyatsi, hanyuma ugahura na silikoni yamazi mubushyuhe bwinshi. Kuri ubu, karubone iri mubutaka ihura nigitangaza cyimiti hamwe na Si yinjiye, ikabyara β - SiC kandi igahuza cyane na α - SiC. Muri icyo gihe, silikoni yubusa yuzuza imyenge, amaherezo ikabona ibikoresho byubutaka bwuzuye cyane.
Ibuye rikomeza imfuruka
Gukora reaction ya silicon carbide ceramics ninshingano zingirakamaro kandi zingenzi mumatara atandukanye yubushyuhe bwo hejuru. Kurugero, mumatara yumusaruro wibumba nka feri ya roller, itanura ya tunnel, itanura rya shitingi, nibindi, bikozwe mubice byingenzi nkamaboko ya nozzle, umuzingo wa crossbeam, hamwe nu miyoboro ikonje ikonje.
Ikirimi cya flame nozzle gishobora kugenzura neza ubushyuhe bwimbere mu itanura. Ifite ibiranga imbaraga zubushyuhe bwo hejuru, kurwanya okiside, kurwanya kwambara, no kurwanya ubukonje bwihuse nubushyuhe. Ntabwo izavunika cyangwa ngo ihindurwe nyuma yigihe kirekire cyo gukoresha ubushyuhe bwo hejuru, byemeza ko ubushyuhe budahinduka mumatara. Nibyingenzi kurasa ibicuruzwa byiza byubutaka bwiza.
Imizinga ya crossbeam hamwe numuyoboro ukonje ufite inshingano zingenzi zo gushyigikira no guhumeka. Uruziga rwa crossbeam rufite ibiranga ubushyuhe bwiza bwumuriro, kurwanya okiside, hamwe nubushyuhe bwo hejuru. Ntibyoroshye guhindura no kunama nyuma yo kumara igihe kinini ukoresheje ubushyuhe bwinshi, ukareba neza imiterere yimbere yimbere y itanura no gutwara ibintu neza. Umuyoboro ukonje ufite inshingano zo kugenzura imyuka ya gaze no gukwirakwiza ubushyuhe mu itanura, bigatuma imikorere isanzwe y’itanura.
Urebye ibice byabigenewe, reaction ya silicon karbide ifite ibyiza bigaragara mugukora ibice by'itanura. Bitewe nubunini bwacyo budahindutse mbere na nyuma yo gucumura, birashobora gutunganywa muburyo ubwo aribwo bwose nyuma yo kubumba. Abakora itanura barashobora gutandukanya imiterere itandukanye hamwe nibisobanuro byibigize ukurikije ibishushanyo mbonera bitandukanye nibikenerwa mu musaruro, byujuje ibisabwa kugirango habeho umusaruro w’ibicuruzwa binini kandi binini, bigoye kubindi bikoresho kubigeraho.
Umurongo ukomeye wo kwirwanaho wa sisitemu ya desulfurizasi
Mu rwego rwo kurengera ibidukikije nka desulfurizasi y’amashanyarazi, reaction ya sinteri ya silicon carbide ceramics nayo igira uruhare runini, bigaragarira cyane cyane mubintu byingenzi bigize nozzles. Umwuka wa flue uva mu mashanyarazi urimo imyanda myinshi ihumanya nka dioxyde de sulfure, na nozzles ya desulfurizasi ni ibikoresho byingenzi byo gukuraho ibyo bihumanya.
Igisubizo cyacumuye silicon carbide desulfurisation nozzle ifite ibintu byiza cyane nkimbaraga nyinshi, ubukana bwinshi, kurwanya ruswa ikomeye, kwihanganira kwambara, no kurwanya ubushyuhe bwinshi. Ifite ubuzima bwa serivisi budasanzwe mubihe bibi, bitagereranywa nibikoresho bisanzwe. Ubwoko bukoreshwa muburyo bwa desulfurizasiya burimo nozle izunguruka hamwe na vortex nozzles, bifite ibishushanyo bitandukanye n'amahame y'akazi, ariko birashobora gukora atomize neza desulfurizer kandi ikabihuza neza na gaze ya flue, bityo bikagera ku ngaruka nziza ya desulfurizasi.
Binyuze muburyo budasanzwe bwubatswe, nozzle izenguruka ituma amazi yo murwego rwo hanze akubita hejuru yumuzenguruko ku mpande runaka kuri nozzle, agahindura icyerekezo cyo gutera hanyuma akava muri nozzle, agakora umurima ukomeye wibicu, ushobora gutanga impande zitandukanye za spray, kandi uracyafite ubushobozi bwo kwinjiza cyane munsi yumuvuduko muto. Vortex nozzle yemerera kwihuta kwinjira mucyumba kizunguruka cya nozzle uhereye ku cyerekezo gifatika, hanyuma ugasohoka uva muri orifice ku mfuruka iburyo ugana icyerekezo cyinjira. Imiti ni ntoya kandi imwe, kandi umuyoboro wa vortex nini, ntabwo byoroshye guhagarika.
Kubice byabigenewe bya sisitemu ya desulfurizasiya, karibide ya silicon ya reaction irashobora guhitamo imiterere ikwiye ya nozzle, ingano, hamwe na spray ikurikije inzira zitandukanye za desulfurizasi, igipimo cy’imyuka ya gazi, kwibanda hamwe, hamwe nibindi bipimo, bigatuma imikorere ikora neza kandi ihamye ya sisitemu yo kwangiza no kubahiriza ibidukikije bikenewe cyane.
Imyitwarire ya silicon karbide ceramics igira uruhare rudasubirwaho mubikorwa byinganda gakondo nkitanura na sisitemu ya desulfurizasi kubera imiterere yihariye nibyiza byihariye. Zitanga ingwate ihamye yimikorere inoze, ihamye, kandi yangiza ibidukikije yumusaruro winganda kandi itera imbaraga zikomeye mukuzamura ikoranabuhanga no guteza imbere inganda gakondo.
