Gukuraho ivumbi ryo mu itanura rizenguruka birushaho kuba byiza cyane mu itsinda rikomeye

Muri iki gihe, igitutu cy’uruganda rukora ibyuma bizenguruka mu itanura ni kinini cyane. Muri byo, uburyo bwo gukuraho ivumbi ry’imyuka izenguruka mu itanura ni bwo bw’ingenzi kurusha ubundi, kandi ni ngombwa gushyira mu bikorwa impinduka nziza kugira ngo hagerwe ku ibyuka bihumanya ikirere bike cyane. Kubwibyo, guhitamo no gukoresha ikoranabuhanga ryo gukuraho ivumbi mu itanura rizenguruka neza, rifite umutekano kandi ridakoresha cyane byabaye ingingo yihutirwa ku bigo by’ibyuma n’ibyuma.

Uburyo bwo gutose n'uburyo bw'umuvuduko bwo kuzunguruka imyuka yo mu itanura bifite ibyiza byabyo

Ikoranabuhanga ryo gukuraho ivumbi mu itanura rizunguruka rigizwe na OG. OG ni incamake ya Oxygen roting furnace Gas Recovery mu Cyongereza, bivuze oxygen roting furnace gas recovery. Ifuru izunguruka ikoresheje ikoranabuhanga rya OG itanga ingano nini ya CO flue gaze mu itanura ifite ubushyuhe bwinshi kandi ifite imbaraga nyinshi bitewe n’ingaruka zikomeye za oxidation mu gihe cyo guhumeka. Imyuka izunguruka igabanya ukwinjira k’umwuka uyikikije binyuze mu kuzamura ijipo no kugenzura umuvuduko w’umwuka uzunguruka mu gipfundikizo. Mu gihe idatwitswe, ikoranabuhanga rikoresha vaporized cooling flue kugira ngo ikonjeshe flue gaze, kandi nyuma yo gusukurwa n’icyuma gikusanya ivumbi cya Venturi gifite ibyiciro bibiri, yinjira muri sisitemu yo kugarura no kurekura gaze.

Ikoranabuhanga ryo gukuraho ivumbi ryumye mu itanura rizunguruka rigizwe n'amagambo make nkaLT.IcyoLTUburyo bwateguwe ku bufatanye na Lurgi na Thyssen bo mu Budage.LTni incamake y'amazina y'ibigo bibiri. Iri koranabuhanga rikoresha icyuma gikonjesha umwuka mu gukonjesha umwuka uva mu kirere, kandi nyuma yo gusukurwa na cylindrical dry electrostatic precipitator, ryinjira muri sisitemu yo kugarura no kurekura umwuka. Iri tegeko ryatangiye gukoreshwa mu mishinga yo kugarura umwuka mu 1981.

Ikoranabuhanga ryo gukuraho ivumbi ry’ifuru rizunguruka rifite ishoramari rinini rimwe, imiterere igoye, ibikoresho byinshi bikoreshwa, kandi rigoranye cyane mu bya tekiniki. Igipimo cyo kwamamaza isoko mu gihugu cyanjye kiri munsi ya 20%. Byongeye kandi, ikoranabuhanga ryo gukuraho ivumbi ryumye rikoresha icyuma kinini cyuma gikuraho ivumbi ry’ifuru rizunguruka ry’ibanze. Igikoresho cyo gukusanya ivumbi cyoroshye kwegeranya kandi ivumbi risohoka ntirihamye.

Ugereranyije n'uburyo bwo gukuraho ivumbi ryumye, uburyo bwo gukuraho ivumbi ryumye bwa OG bufite imiterere yoroshye, buhendutse, kandi bufite ubushobozi bwo gusukura neza, ariko bufite ingaruka mbi nko gukoresha ingufu nyinshi, gukoresha amazi menshi, gutunganya imyanda igoye, ndetse n'ikiguzi kinini cyo kuyikoresha. Byongeye kandi, ikoranabuhanga ryo gukuraho ivumbi ryumye rijyana ivumbi ryose mu mazi hatitawe ku bunini bw'uduce, bigatuma amazi yumye menshi akurwaho ivumbi. Nubwo urwego rwa tekiniki rwo gukuraho ivumbi ryumye n'ivumbi rwakomeje kunozwa mu buryo bwo gushyira mu mwanya waryo, inenge zaryo ntizirakemuka.

Mu gusubiza iki kibazo cyavuzwe haruguru, impuguke mu nganda zatanze igitekerezo cy’ikoranabuhanga ryo gukuraho ivumbi ryumye mu myaka yashize, ryatejwe imbere mu Bushinwa. Kuri ubu, umubare w’amatanura azunguruka akoresha ikoranabuhanga ryo gukuraho ivumbi ryumye urenze umubare w’amatanura azunguruka akoresha ikoranabuhanga ryo gukuraho ivumbi ryumye. Uburyo bwo gukuraho ivumbi ryumye bukoresha icyuma gikonjesha cyumye kugira ngo gisubize 20%-25% by’ivu ryumye, rigumana ibyiza byo gukuraho ivumbi ryumye kandi rigatsinda inenge z’ikoranabuhanga ryo gukuraho ivumbi ryumye n’iry’amazi. By’umwihariko, iri koranabuhanga rishobora guhindura uburyo bwo gukuraho ivumbi ryumye hatabayeho kuyisenya no kuyivugurura burundu nk’uburyo bwo gukuraho ivumbi ryumye, kugira ngo ibikoresho bya mbere bishobore kugumana ku rugero runini kandi amafaranga y’ishoramari agabanuke.
