Chikonzero 1: Kutadza kwekushisa kwakanyanya
Kureba kwenguva yakareba tembiricha mamiriro eSCR catalyst anokonzeresa kupisa tembiricha, izvo zvinoderedza simbi yekushanda simba muSCR catalyst, nekudaro ichideredza zvakanyanya chiitiko checatalyst.Kunyangwe injini iri muchimiro chakanaka uye yakanyatsogadziriswa, akasiyana migwagwa mamiriro anokonzeresa yakawandisa SCR catalyst tembiricha yekushandiswa kwayo zvisina kunaka.
Chikonzero chechipiri: chepfu yemakemikari
Precious metal catalyst pa SCR catalyst carrier ine adsorption yakasimba pasarufa, phosphorus, carbon monoxide, incombustibles isina kukwana, lead, manganese, etc. Panguva imwecheteyo, noble metal catalyst ine yakasimba oxidation catalysis, iyo inoita kuti adsorbed isina kukwana inopisa mafuta edizeli ive nyore. kuve oxidized, condensed uye polymerized kuita colloidal carbon deposit, zvichikonzera kuvharika kweSCR catalyst.
Chikonzero chechitatu: kabhoni dhipoziti blockage deactivation
Iyo blockage ye SCR catalyst kabhoni dhipoziti inoumbwa zvishoma nezvishoma, iyo inodzoreredzwa.Iyo blockage inogona kuderedzwa nemakemikari maitiro senge oxidation uye gasification, kana nemaitiro emuviri senge desorption uye evaporation yezvinhu zvinoputika uye gasi zvinhu.
Chikonzero chechina: Kuwandisa kwemugwagwa
Iyo SCR catalyst inogona kuvharika kana uchityaira mumigwagwa yakatsvikinyidzana nekuda kwehuwandu hwehuwandu hwekupisa husina kukwana hunogadzirwa nemotokari panguva yekumhanyisa uye kuderera.
Chikonzero 5: Hapana kubvisa, kuchenesa uye kugadzirisa
Sezvo huwandu hukuru hwecolloid kabhoni huchagezwa pasi panguva yekuchenesa, zviri nyore kuita kuti SCR catalyst ivharwe, icho chiriwo chikonzero chekuwedzera kushandiswa kwemafuta emamwe mota mushure mekugadzirisa pasina disassembly.
Chikonzero chechitanhatu: Bambo rakasimba kana kukwevera pasi
Iyo catalytic inotakura yecatalyst ndeye ceramic kana simbi mudziyo.Mushure mekunge mota ine SCR catalyst ceramic catalyst carrier yadhonzwa, kudhumhana kwakanyanya kunogona kutyora musimboti weceramic wecatalyst woirasa.
Chikonzero 7: Kutadza kwemafuta ekupa system
Dunhu remafuta inzvimbo ine kukundikana kwakawanda.Kunyange zvazvo masisitimu mazhinji epamberi ekudzora enjini ave aine mabasa ekuzvidzivirira, kana silinda ikangotadza, komputa inodzima kamwe kamwe jekiseni remafuta rehumburumbira yodzivirira kuti isapise mafuta kuitira kudzivirira injini uye chinokonzeresa, michina mishoma ine zvakadaro. mabasa epamberi mushure mezvose, uye michina mizhinji haina mabasa akadaro parizvino.
Chikonzero 8: Mushure mekutadza kwehurongwa hwekurapa
Apo iyo urea pombi mumashure ekurapa ine matambudziko;Iyo muromo paurea system yakavharwa kana ine matambudziko emhando;Iyo urea pachayo haina kukodzera;Kubuda kwemuswe gasi pombi;Izvo zvinotungamira kune hurombo atomization mhedzisiro yeurea jekiseni.Mushonga weurea unopfapfaidzwa zvakananga pamadziro epombi epombi.Panguva imwecheteyo, nokuti pombi yemuswe inogara iri pakupisa kwepamusoro, mvura iri nyore kubuda, iyo inotungamirira kukristalllization.
