Nk'igice cy'ingenzi cy'uburyo bugezweho bwo gusukura imyuka ihumanya ikirere,Utuzu twa FGD twa karubide ya silikonibigira uruhare runini mu nganda nko mu ngufu z'ubushyuhe n'ubutare. Uyu muyoboro wa silicon carbide ceramic wakemuye neza ikibazo cy'imiyoboro gakondo y'ibyuma mu gihe cy'ubushyuhe bwinshi n'ingufu nyinshi binyuze mu miterere mishya y'inyubako n'ubuhanga mu bikoresho, binongera cyane imikorere myiza yo gusukura ibyuma.
1, Imiterere y'ibikoresho ni yo ishingira ku mikorere myiza
Ubukomere bwa Mohs bwaibumba rya karubide rya silikoniIgera kuri 9.2, ikaba iya kabiri nyuma ya diyama, kandi gukomera kwayo gucika ni inshuro eshatu ugereranyije n’ibumba rya alumina. Iyi miterere ya kristu ikora neza cyane ituma ibikoresho birwanya kwangirika, kandi bitewe n’uruvange rw’amazi rwihuta rurimo kristu za gypsum (umuvuduko w’amazi ugera kuri 12m/s), igipimo cyo kwangirika kw’ubuso ni 1/20 gusa cy’imiyoboro y’icyuma. Mu bidukikije bisimburana na aside hamwe n’ishingiro bifite pH ya 4-10, igipimo cyo kwangirika kwa silicon carbide kiri munsi ya 0.01mm/umwaka, bikaba ari byiza cyane kuruta 0.5mm/umwaka by’icyuma kitagira umugese cya 316L.
Igipimo cyo kwaguka k'ubushyuhe bw'ibikoresho (4.0 × 10 ⁻⁶/℃) kiri hafi y'icyuma, kandi gishobora gukomeza kubungabunga imiterere y'ibikoresho mu gihe ubushyuhe bwa 150 ℃ buhagaze. Ibumba rya silicon carbide ryakozwe hakoreshejwe uburyo bwo gushwanyaguza ibintu rifite ubucucike burenze 98% n'ubuso buri munsi ya 0.5%, bikarinda kwangirika kw'imiterere y'ibikoresho guterwa no kwinjira mu buryo buciriritse.
2, Uburyo bwo gutunganya neza atomization n'uburyo bwo kugenzura imiterere y'amazi
Itsindaumunwa w'uruziga rwa silikoni karubidebyongera cyane umuvuduko wo kuzenguruka kw'urutare, kandi iyo umwobo usohoka neza, ugabanya urutare rw'amabuye y'agaciro mo uduce duto kandi dusa. Igipimo cyo gupfundikira umuyoboro w'amazi ukozwe muri uru rukuta ni kinini cyane, kandi igihe cy'ibitonyanga mu munara cyongerwaho amasegonda 2-3, 40% hejuru y'igihe cy'imiyoboro gakondo.
3, guhuza sisitemu no kunoza imikorere y'ubuhanga
Mu munara usanzwe wo gusukura,imiyoboro ya FGD ya karubide ya silikoniHakoreshejwe uburyo bwa chessboard, intera iri hagati ya 1.2-1.5 n'umurambararo wa spray cone, igakora urwego rwa 3-5 rw'ibice bitwikiriye. Iyi gahunda igenzura ko uburebure bw'umunara wo gusukura umuyaga burenga 200%, bigatuma habaho guhuza guhagije hagati y'umwuka uva mu kirere n'umuyoboro w'amazi. Iyo umunara urimo ubusa utemba wa 3-5 m/s, igihombo cy'umuvuduko wa sisitemu kigenzurwa mu ntera iri hagati ya 800-1200 Pa.
Amakuru y’imikorere agaragaza ko ubushobozi bwo gukuraho isukari mu buryo bwa FGD hakoreshejwe imiyoboro ya silicon carbide bukomeje kuba bwiza ku kigero kirenga 97.5%, kandi ubushuhe bw’ibikomoka kuri gypsum bugabanuka bukagera munsi ya 10%. Igihe cyo kubungabunga ibikoresho cyongerewe kuva ku mezi 3 ku miyoboro y’icyuma kikagera ku myaka 3, kandi ikiguzi cyo gusimbuza ibice bisigaye cyagabanutseho 70%.
Ishyirwa mu bikorwa ry'ibiUmunwa wa FGDIgaragaza intambwe iva ku bikoresho binini bigamije kurinda ibidukikije ikagera ku bikoresho bifatika byo kurinda ibidukikije. Ikoranabuhanga rya keramike rya 3D rimaze gukura, imiterere y’imiyoboro y’amazi ishobora kugerwaho mu gihe kizaza, ibi bikaba bishobora kongera imikorere ya atomike ku kigero cya 15-20% no guteza imbere ikoranabuhanga ryo kugabanya cyane imyuka ihumanya ikirere kugira ngo ryinjire mu cyiciro gishya cy’iterambere.
