Isizathu 1: Ukungaphumeleli kobushushu obuphezulu
Iimeko zexesha elide zokushisa okuphezulu kwe-SCR catalyst ziya kubangela ukucima ukushisa okuphezulu, okuya kunciphisa amandla okusebenza kwesinyithi kwi-SCR catalyst, ngaloo ndlela kunciphisa kakhulu umsebenzi we-catalyst.Nokuba injini ikwimeko entle kwaye ilungiswa ngokufanelekileyo, iimeko zendlela ezahlukeneyo ziya kubangela ubushushu obugqithisileyo be-SCR ye-catalyst yokusetyenziswa kwayo ngokungafanelekanga.
Isizathu sesi-2: ityhefu yekhemikhali
Isixhobo sesinyithi esixabisekileyo kwi-SCR catalyst carrier sine-adsorption eyomeleleyo kwisulfure, i-phosphorus, i-carbon monoxide, izinto ezinokutsha ezingaphelelanga, ilothe, i-manganese, njl. Kwangaxeshanye, i-catalyst yentsimbi ehloniphekileyo ine-oxidation catalysis eyomeleleyo, eyenza ukuba i-oyile ye-adsorbed evuthayo engaphelelanga ibe lula. ukuba i-oxidized, i-condensed kunye ne-polymerized ukwenza idiphozithi ye-colloidal carbon, ebangela ukuvaleka kwe-SCR catalyst.
Isizathu sesi-3: ukuvalwa kwe-carbon deposit deactivation
Ukuvalwa kwe-SCR catalyst carbon deposit yenziwa ngokuthe ngcembe, eguqulwayo.Ukuvaleka kunokuncitshiswa ngeenkqubo zeekhemikhali ezifana ne-oxidation kunye ne-gasification, okanye ngeenkqubo zomzimba ezifana nokuchithwa kunye nokuphuma kwe-evaporation yamacandelo aguquguqukayo kunye ne-gaseous components.
Isizathu 4: Ukuxinana kweendlela
I-catalyst ye-SCR inokuthi ivalwe xa uqhuba kwiindlela ezixineneyo ngenxa yobuninzi bezinto ezinokutsha ezingaphelelanga eziveliswa zizithuthi ngexesha lokukhawuleza kunye nokunciphisa.
Isizathu sesi-5: Akukho kuchithwa, ukucocwa kunye nokugcinwa
Njengoko ubuninzi bekhabhoni ye-colloid iya kuhlanjululwa ngexesha lokucoca, kulula ukubangela ukuba i-catalyst ye-SCR ivalwe, okusisizathu sokunyuka kokusetyenziswa kwepetroli kwezinye izithuthi emva kokugcinwa ngaphandle kokuchithwa.
Isizathu sesi-6: Iqhuma elibi okanye ukutsaleka ezantsi
I-catalytic carrier ye-catalyst yi-ceramic okanye isixhobo sensimbi.Emva kokuba isithuthi esine-SCR catalyst catalyst catalyst carrier sitsalwa, ungquzulwano olumandla lunokwaphula umbindi we-ceramic we-catalyst kwaye uyilahle.
Isizathu sesi-7: Ukusilela kwenkqubo yokubonelela ngamafutha
Isekethe yeoli yindawo enokusilela okuninzi.Nangona iinkqubo ezininzi zolawulo lwe-injini eziphucukileyo ngoku zinemisebenzi yokuzikhusela, xa isilinda isilele, ikhompyutha iya kuzinqumla ngokuzenzekelayo isitofu se-fuel se-cylinder kwaye iyithintele ekuboneleleni ngamafutha ukuze ikhusele i-injini kunye ne-catalyst, bambalwa oomatshini abanaloo nto. imisebenzi ephambili emva kwayo yonke loo nto, kwaye oomatshini abaninzi abanayo imisebenzi enjalo ngoku.
Isizathu se-8: Emva kokungaphumeleli kwenkqubo yonyango
Xa impompo ye-urea kwisithuba sonyango ineengxaki;I-nozzle kwinkqubo ye-urea ivaliwe okanye ineengxaki zomgangatho;I-urea ngokwayo ayifanelekanga;Ukuvuza kombhobho werhasi yomsila;Kuya kukhokelela kwisiphumo esibi se-atomization yenaliti ye-urea.Isisombululo se-urea sitshizwe ngokuthe ngqo kudonga lombhobho wokukhupha.Ngelo xesha, ngenxa yokuba umbhobho womsila uhlala ubushushu obuphezulu, amanzi alula ukuphuphuma, okukhokelela kwi-crystallization.
