Isimiso:
Inzwa ye-oxygen iwukucushwa okujwayelekile emotweni.Isebenzisa izinto ezizwelayo ze-ceramic ukukala amandla komoya-mpilo epayipini lokukhipha umoya wemoto, futhi ibala ukugcwala komoyampilo okuhambisanayo ngesimiso sebhalansi yekhemikhali ukuze iqaphe futhi ilawule isilinganiso sokusha sikaphethiloli womoya ukuze kuqinisekiswe ikhwalithi yomkhiqizo Kanye nesici sokulinganisa esihlangabezana nokukhipha umoya. ejwayelekile.
Inzwa ye-oxygen isetshenziswa kakhulu ekulawuleni umkhathi wezinhlobo ezahlukene zokuvutha kwamalahle, ukushiswa kukawoyela, ukusha kwegesi, njll. Iyindlela engcono kakhulu yokulinganisa umkhathi wokuvutha okwamanje.Inezinzuzo zesakhiwo esilula, ukusabela okusheshayo, ukugcinwa okulula, ukusetshenziswa okulula, ukulinganisa okunembile, njll. Ukusebenzisa inzwa ukukala nokulawula umoya wokushiswa akukwazi nje ukuzinza nokuthuthukisa ikhwalithi yomkhiqizo, kodwa futhi kufinyeze umjikelezo wokukhiqiza nokonga amandla. .
Ukulungisa
Inzwa ye-oxygen isebenzisa i-Isimiso se-Nernst.
Ingxenye ewumgogodla iyishubhu le-ceramic le-ZrO2 elinezimbobo, okuyi-electrolyte eqinile, enama-electrode angenazimbobo zeplatinamu (Pt) afakwe nhlangothi zombili.Emazingeni okushisa athile, ngenxa yokugcwala okuhlukene komoyampilo ezinhlangothini zombili, ama-athomu omoya-mpilo ohlangothini lokugxila okuphezulu (uhlangothi lwangaphakathi lweshubhu le-ceramic 4) akhangiswa ku-electrode yeplatinamu futhi ahlanganiswe nama-electron (4e) ukuze akhe. I-oxygen ion O2-, eyenza i-electrode ishajwe kahle, i-O2 -Ama-ion athuthela ohlangothini oluphansi lwe-oxygen concentration (i-exhaust gas side) ngokusebenzisa izikhala ze-ion oxygen ku-electrolyte, ukuze i-electrode ishajwe kabi, okungukuthi, okungenzeka umehluko uyakhiqizwa.
Uma isilinganiso sikaphethiloli womoya siphansi (ingxube ecebile), kuba ne-oksijini encane kugesi ephumayo, ngakho-ke kukhona ama-ion oksijini amancane ngaphandle kweshubhu le-ceramic, okwenza amandla e-electromotive angaba ngu-1.0V;
Uma isilinganiso sikaphethiloli womoya silingana no-14.7, amandla e-electromotive akhiqizwa ezinhlangothini zangaphakathi nangaphandle zeshubhu le-ceramic ngu-0.4V~0.5V, futhi la mandla e-electromotive angamandla e-electromotive eyireferensi;
Uma isilinganiso sikaphethiloli womoya siphezulu (ingxube engenawo amandla), okuqukethwe komoyampilo egesini yokukhipha umoya kuphezulu, futhi umehluko wokuhlushwa kwe-ion ion yomoya-mpilo phakathi kwangaphakathi nangaphandle kweshubhu le-ceramic mncane, ngakho amandla e-electromotive akhiqizwayo aphansi kakhulu, eduze ku-zero.
Umsebenzi
Umsebenzi wenzwa ukunquma ulwazi mayelana nokuthi kukhona i-oksijini eyeqile endaweni yokukhipha umoya ngemva kokusha kwenjini, okungukuthi, okuqukethwe komoyampilo, futhi iguqule okuqukethwe komoyampilo ibe isignali kagesi bese iyidlulisela kukhompyutha yenjini, ngakho-ke. ukuthi injini ikwazi ukubona isilawuli se-loop evaliwe ngesici somoya esidlule njengethagethi;ukuqinisekisa;Isiguquli se-catalytic sezindlela ezintathu sisebenza kahle kakhulu ekuguquleni ezintweni ezintathu ezingcolisa ama-hydrocarbon (HC), i-carbon monoxide (CO) nama-nitrogen oxides (NOX) kugesi yokukhipha umoya, futhi sandisa ukuguqulwa nokuhlanzwa kokungcola .
Inhloso
Izinzwa zomoya-mpilo zisetshenziswa kakhulu ezimbonini ezifana ne-petroleum, amakhemikhali, amalahle, i-metallurgy, ukwenza amaphepha, ukuvikelwa komlilo, ukuphathwa kukamasipala, imithi, izimoto, nokuqapha ukukhishwa kwegesi.
I-YASEN iyingcweti yebhizinisi lokukhiqiza ekukhiqizeni izinzwa zomoya-mpilo we-VM, uma uzidinga, wamukelekile ukuthintana nathi!
