Nyaya |Nzira yekushandisa sei mafuta-isina screw blowers uye centrifugal blowers yekuchinja-kuchengetedza simba muindasitiri yesimende?
SCR denitrification tekinoroji, kureva, inosarudzika nzira yekudzikisa, gasi reammonia rinopfapfaidzwa mune yepamusoro-tembiricha flue gasi denitrification mudziyo se denitrification agent.Pasi pechiito checatalyst, iyo NOx mune flue gasi yakaora kuita isiri-chepfu uye isina kusvibiswa-isina N₂ uye H₂O.Muchishandiso cheSCR dhizaini, mwero we denitrification unosvika 80-90%, uye kupukunyuka kweammonia kuri pazasi 3 mg/Nm³, izvo zvinonyatsoenderana nekuwedzera kwepamusoro denitrification zvinodikanwa zvezvirimwa zvesimende.
① Liquid ammonia inotumirwa kubva kumvura ammonia tangi rori kuenda kune yemvura ammonia yekuchengetedza tangi neiyo yekuburitsa compressor.
②Mushure mekubuda muammonia mune evaporation tank, inopinda munzvimbo yebhailer kuburikidza neammonia buffer tank uye pombi yekufambisa.
③Mushure mekusangana zvakaenzana nemhepo, inopinda muSCR reactor kuburikidza nevharuvhu yekugovera pilot yemukati mekuita.Iyo SCR reactor yakaiswa pamberi pemhepo preheater, uye iyo ammonia gasi iri pamusoro peiyo SCR reactor.
④Sanganisa utsi zvakaenzana kuburikidza nechinhu chakakosha chekupfapfaidza
⑤Mushure mekusanganiswa, iyo flue gasi inopfuura nepakati peiyo catalyst layer mune reactor yekudzikisa kuita.
Air compressor air soot blowing tekinoroji
Paunenge uchisarudza iyo soot kuridza nzira, kuwedzera kune soot kuvhuvhuta mhedzisiro, iyo yekupfeka mhedzisiro pacatalyst inofanirwawo kutariswa.Parizvino, nzira dzekufuridza soot dzinowanzo shandiswa muSCR denitration masisitimu dzinosanganisira sonic soot blowing, steam soot kuvhuvhuta uye compressed air soot kuvhuvhuta.
Yakasanganiswa nehunhu hwesimende utsi hwehuni uye guruva, zvakaoma kune sonic soot blowers kuti ienderane kune yakakura uye yakakwirira viscosity ye simenti kiln flue gasi guruva.Pamusoro pezvo, kugadzirwa kwegasi musimende idiki, saka zvinonyanya kukodzera kushandisa mweya wakamanikidzwa kuridza soot.
Mumakore achangopfuura, nekuvandudzwa uye kusimudzira indasitiri yesimende mumunda wekuchengetedza kwezvakatipoteredza, emission standards yakawedzera kusimudzwa.Kudzivirira uye kutonga kwekusvibiswa kwemhepo uye kudzikiswa kweflue gasi nitrogen oxide emissions ave mabasa echimbichimbi anotarisana nemabhizinesi ekugadzira simende.SCR (Catalytic Reduction) tekinoroji ine yakakwira denitrification kunyatsoita uye inokwanisa kuwana yakanyanya-yakaderera emissions yeflue gasi nitrogen oxides uye ammonia kupukunyuka pasi pemamiriro ekushomeka kweammonia.Mumakore achangopfuura, simende kiln flue gasi SCR tekinoroji yakaitawo imwe fambiro mberi, ichipa vimbiso inoshanda kumakambani esimende kuti awane ultra-low emissions.
