Kungani Khetha Isixhumi Esisheshayo Sepulasitiki Sesistimu ye-Urea SCR?
Uhlelo lwe-Urea Selective Catalytic Reduction (SCR) seluyingxenye ebalulekile ezinjinini zesimanje zikadizili ukuze kwehliswe ukungcola okuyingozi.Lesi simiso sincike ekulethweni okunembile nangempumelelo kwesisombululo se-urea kumfudlana we-exhaust, lapho sihlangana nama-nitrogen oxides ukuwaguqula abe yi-nitrogen namanzi angenabungozi.Ukuqinisekisa ukusebenza kahle kohlelo lwe-Urea SCR, ukusetshenziswa kwezingxenye zekhwalithi ephezulu njengezixhumi ezisheshayo zepulasitiki kubalulekile.Kulesi sihloko, sizohlola izizathu zokuthi kungani ukukhetha izixhumi ezisheshayo zepulasitiki zohlelo lwe-Urea SCR kuyisinqumo esihlakaniphile.
Ukusebenziseka kalula ekushintsheni nasekulungiseni
Enye yezinzuzo ezibalulekile zokusebenzisa izixhumi ezisheshayo zepulasitiki ohlelweni lwe-Urea SCR wukuba lula abakunikezayo mayelana nokushintshwa nokulungisa.Izixhumi ezisheshayo zepulasitiki ezijwayelekile ze-SAE zenzelwe ukuthi zifakwe kalula futhi zisuswe, okuvumela ukunakekelwa okusheshayo nokungenazinkinga.Lokhu kubaluleke kakhulu kumongo wesistimu ye-Urea SCR, lapho noma yisiphi isikhathi sokuphumula singaholela ekwandiseni ukukhishwa kwekhabhoni kanye nokungahle kube nokungahambisani nemithetho yemvelo.Ngezixhumi ezisheshayo zepulasitiki, ochwepheshe bangashintsha ngokushesha noma balungise izingxenye, banciphise isikhathi sokuphumula sesistimu futhi baqinisekise ukusebenza kwalo okuqhubekayo.
Ukuqina Nokwethenjelwa
Izixhumi ezisheshayo zepulasitiki ezidizayinelwe uhlelo lwe-Urea SCR zakhelwe ukumelana nezimo zokusebenza ezinzima ezihlangatshezwana nazo ezinhlelweni zezimoto.Akhiwe ngezinto zekhwalithi ephezulu ezinikeza ukumelana okuhle kakhulu nokugqwala, ukudlidliza, nokuhamba ngebhayisikili okushisayo.Lokhu kuqina kuqinisekisa ukuthi izixhumi zigcina ubuqotho bazo esikhathini sempilo yesistimu, okunikela ekusebenzeni kwayo okuthembekile.Ukwengeza, ukusetshenziswa kwezixhumi ezisheshayo zepulasitiki kususa ingcuphe yokugqwala kwe-galvanic engenzeka lapho izinsimbi ezingafani zihlangana, kuthuthukise ukwethembeka kwesistimu.
Ukuhambisana nokusebenza
Izixhumi ezisheshayo zepulasitiki zenzelwe ukuhlangabezana nezidingo eziqinile zesistimu ye-Urea SCR, ukuqinisekisa ukuhambisana nesisombululo se-urea nezinye izingxenye zesistimu.Izixhumi zenzelwe ukuhlinzeka ngoxhumano oluvikelekile nolungavuzi, luvimbele noma yikuphi ukulahlekelwa okungaba khona kwesixazululo se-urea nokugcina ukusebenza kahle kwesistimu.Ngaphezu kwalokho, ukwakheka okunembile kwezixhumi ezisheshayo zepulasitiki kunciphisa imikhawulo yokugeleza, okuvumela ukulethwa okushelelayo nokungashintshi kwesixazululo se-urea ku-catalyst, ngaleyo ndlela kuthuthukisa ukusebenza kwesistimu.
Izindleko-Ngempumelelo
Ngaphezu kwezinzuzo zabo zobuchwepheshe, izixhumi ezisheshayo zepulasitiki zinikeza isisombululo esingabizi kakhulu sohlelo lwe-Urea SCR.Ukwakhiwa kwazo okungasindi kanye nenqubo yokufaka eyenziwe lula kunomthelela ekwehleni kwezindleko zomsebenzi nokuhlanganisa.Ngaphezu kwalokho, ukuqina nokuthembeka kwezixhumi ezisheshayo zepulasitiki kunciphisa isidingo sokushintshwa nokulungiswa njalo, okuholela ekongeni kwezindleko zesikhathi eside kubakhiqizi bezimoto nabaqhubi.
Ukucatshangelwa Kwemvelo
Ukusetshenziswa kwezixhumi ezisheshayo zepulasitiki kuhambisana nokugcizelela okukhulayo kokusimama kanye nesibopho semvelo embonini yezimoto.Lezi zixhumi zivame ukwakhiwa kusetshenziswa izinto ezigaywa kabusha, ezinomthelela ekwehliseni umthelela wendawo.Ngaphezu kwalokho, ukusebenza kahle kohlelo lwe-Urea SCR, olwenziwa izixhumi ezisheshayo zepulasitiki zekhwalithi ephezulu, kuholela ekukhiqizweni okuphansi kwe-nitrogen oxides, ukukhuthaza umoya ohlanzekile nokuhambisana nemithethonqubo yokukhipha umoya.
Sengiphetha, ukukhethwa kwezixhumi ezisheshayo zepulasitiki zohlelo lwe-Urea SCR kunikeza inqwaba yezinzuzo, okuhlanganisa lula ukushintshwa nokulungiswa, ukuqina, ukuhambisana, ukuphumelela kwezindleko, nokucatshangelwa kwemvelo.Ngokukhetha izixhumi ezisheshayo zepulasitiki zekhwalithi ephezulu ezihlangabezana nezindinganiso ze-SAE, abakhiqizi nabaqhubi bangaqinisekisa ukusebenza kahle nokuthembeka kwesistimu ye-Urea SCR, ekugcineni kube negalelo emoyeni ohlanzekile kanye nezinto zokuhamba ezisimeme.
