Isizathu 1: Ukwehluleka kwezinga lokushisa eliphezulu
Izimo zokushisa eziphakeme zesikhathi eside ze-SCR catalyst zizobangela ukucisha ukushisa okuphezulu, okuzonciphisa amandla okusebenza kwensimbi ku-catalyst ye-SCR, ngaleyo ndlela kunciphise kakhulu umsebenzi we-catalyst.Ngisho nalapho injini isesimweni esihle futhi ilungiswe kahle, izimo zomgwaqo ezihlukene zizobangela izinga lokushisa elinamandla le-SCR le-catalyst ukuze lisetshenziswe ngokungafanele.
Imbangela 2: ubuthi bamakhemikhali
I-precious metal catalyst ku-SCR catalyst catalyst ine-adsorption eqinile ku-sulphur, i-phosphorus, i-carbon monoxide, izinto ezivuthayo ezingaphelele, umthofu, i-manganese, njll. Ngesikhathi esifanayo, i-noble metal catalyst ine-catalysis eqinile ye-oxidation, eyenza izinto ezivuthayo ezingaphelele ze-adsorbed zibe lula zikadizili. ifakwe i-oxidized, ifinyezwe futhi yenziwe i-polymerized ukuze yenze idiphozithi ye-colloidal carbon, okubangela ukuvinjelwa kwe-SCR catalyst.
Isizathu sesi-3: ukuvalwa kwe-carbon deposit blockage
Ukuvinjwa kwe-SCR catalyst carbon deposit kwakheka kancane kancane, okubuyiseleka emuva.Ukuvinjwa kungancishiswa ngezinqubo zamakhemikhali ezifana ne-oxidation kanye ne-gasification, noma ngezinqubo ezibonakalayo ezifana nokukhipha kanye nokuhwamuka kwezingxenye eziguquguqukayo nezingxenye zegesi.
Isizathu 4: Ukuminyana emgwaqeni
I-catalyst ye-SCR cishe izovinjwa lapho ushayela emigwaqweni eminyene ngenxa yenani eliphakeme lezinto ezivuthayo ezingaphelele ezikhiqizwa izimoto ngesikhathi sokusheshisa nokunciphisa.
Isizathu sesi-5: Akukho ukudilizwa, ukuhlanzwa nokugcinwa
Njengoba inani elikhulu le-colloid carbon lizogezwa phansi ngesikhathi sokuhlanza, kulula ukubangela ukuba i-catalyst ye-SCR ivinjwe, okuyisizathu sokunyuka kokusetshenziswa kukaphethiloli kwezinye izimoto ngemva kokugcinwa ngaphandle kokuhlakazeka.
Isizathu 6: Iqhubu elibi noma ukuhudula phansi
Isithwali se-catalytic se-catalyst iyisisetshenziswa se-ceramic noma sensimbi.Ngemuva kokuthi imoto ene-SCR catalyst ceramic catalyst catalyst idonswa, ukushayisana okukhulu kungase kwephule umongo we-ceramic we-catalyst futhi uyilahle.
Isizathu sesi-7: Ukuhluleka kwesistimu yokuphakelwa kwamafutha
Umjikelezo kawoyela uyindawo enokwehluleka okuningi.Nakuba izinhlelo eziningi ezithuthukisiwe zokulawula izinjini manje sezinemisebenzi yokuzivikela, uma isilinda sihluleka, ikhompuyutha izozinqamula ngokuzenzakalelayo umjovo kaphethiloli we-cylinder futhi iwuvimbele ekunikezeni uphethiloli ukuze kuvikelwe injini kanye ne-catalyst, imbalwa imishini enalokhu. imisebenzi ethuthukisiwe phela, futhi imishini eminingi ayinayo imisebenzi enjalo okwamanje.
Isizathu sesi-8: Ngemva kokuhluleka kwesistimu yokwelapha
Lapho ipompo ye-urea ngemuva kokwelashwa inezinkinga;I-nozzle ohlelweni lwe-urea ivinjiwe noma inezinkinga zekhwalithi;I-urea ngokwayo ayifanelekile;Ukuvuza kwepayipi legesi yomsila;Kuzoholela kumphumela omubi we-atomization womjovo we-urea.Isixazululo se-urea sifafazwa ngokuqondile odongeni lwepayipi lokukhipha umoya.Ngesikhathi esifanayo, ngenxa yokuthi ipayipi lomsila lihlala lishisa kakhulu, amanzi alula ukuhwamuka, okuholela ku-crystallization.
