Mumunda we flue gasi denitration, Guangdong GRVNES Environmental Protection Technology Co., Ltd. yakagadzira 3 + 1 akaturikidzana uye akawedzera denderedzwa reammonia kutiza catalyst kugadzirisa chiitiko chekupukunyuka kweammonia kana imwe ammonia yapera kupfapfaidza, kuti iyo inopfuura. yakapfapfaidzwa ammonia inogona kuburitswa mumhepo mushure mekuita mushure mekushanda.
Kurapa kwe denitration ammonia kupukunyuka kubva GRVNES flue gasi panguva imwe chete kurapwa kwe denitration ammonia kutiza neASC ammonia kutiza catalyst
TechnologyRoadmap
Zvinoenderana nezvinodiwa zvepurojekiti uye mamiriro chaiwo ekuburitsa, Green Valley kuchengetedza kwezvakatipoteredza yakateya nzira yehunyanzvi ye "SCR + ASC" kuti isangane nezvinodiwa zveprojekiti.Iyo tekinoroji nzira yeprojekiti inoratidzwa mumufananidzo uri pazasi:
SCR+ASC
SCR + ASC Technology Roadmap
Mutengo wekuwedzera nitrogen komisheni (NOx) kune injini nguva dzose inogona kuderedzwa neinopfuura 90% kuburikidza necatalytic reduction tekinoroji, uye mutengo unoshanda wenitrogen compounds (NOx) unogona kuderedzwa neinopfuura 5% kuburikidza necatalytic kuderedza tekinoroji. .Uye kumanikidzwa kwemashure kwakaderera, uye panenge pasina kuwedzera kwekumanikidzwa kwemashure mukugadzirisa kushandiswa.
Kushanda Nheyo Dhiyagiramu yeSCR Catalys
Kushanda Nheyo Dhiyagiramu yeSCR Catalys
Kushanda Nheyo yeASC Ammonia Escape Catalyst:
ASC oxidation catalyst inonyanya kuumbwa nekutakura uye catalytic coating.Injini yedhiziri inopedza kuchenesa mudziyo.Chinangwa chikuru chemudziyo ndechekuita oxidize yakawandisa NH3 mudhiziri exhaust system ine O2 kugadzira kusvibiswa-isina N2 uye mvura kunze kweinjini, kuitira kuti uone kubuda kwakachena kwedhiziri.Inogona kushandiswa musanganiswa nedhiziri particle catcher uye denitration yekuchenesa catalyst.
Ignition Temperature
Ndiko kuti, tembiricha iyo iyo catalyst inosvika 50% shanduko inoshanda.Iyo tembiricha yekubatidza yeASC ammonia inopukunyuka catalyst i250 ℃.Kuti uwane kutendeuka kwepamusoro, tembiricha yekupedza injini inofanirwa kunge yakakwira.
Packaging Form
Inogona kuputirwa zvakasiyana kana kupindirana neSCR, iyo inogona kusangana nezvinodiwa zvekushanda kwesevhisi.
Emission Standard:
Ammonia yekutiza mwero ≤ 3ppm
NOx emission kuderedzwa vs ammonia kusvibiswa muindasitiri simende
Nekuda kwekuti tsvagiridzo yefiring system ye simende ichiri munzvimbo yakakura, pachine zvakawanda zvinoshomeka mumamiriro ekushanda muchoto uye magadzirirwo ekugadzira nitrogen oxide muindasitiri yesamende.Kune akawanda masosi enitrogen oxides uye akawanda anofurira zvinhu.Mumunda we nitrogen oxide emission kudzikisa tekinoroji, hunyanzvi huripo huripo hunosanganisira SCR, SNCR, dhigirii kupisa uye zvichingodaro.
SCR inosarudza catalytic kuderedza tekinoroji ndiyo huru denitration tekinoroji munyika.Iine ammonia kana urea se denitration agent uye catalytic selective absorption pasi pechiito checatalyst mushongwe yekunyura, chiyero che denitration chinogona kusvika kupfuura 90%.
SNCR tekinoroji inoshandisa yakakodzera tembiricha nzvimbo (900 ℃ ~ 1100 ℃) muchoto chekuora kuisa musanganiswa weammonia mairi.Panguva iyi tembiricha, ammonia (NH3) inopindirana neNOx muflue gasi kugadzira N2 neH2O.The denitration rate inowanzoita 40% - 60%, kushandiswa kweammonia kwakakura, uye kupukunyuka kweNH3 kwakakwirira, iyo inogona kudarika 3 nguva yeSCR.
Parizvino, mabhizinesi esimende epamba atopedza kuvaka kweSNCR dhitration.Iyi tekinoroji inoshandisa huwandu hukuru hweammonia seNOx inoderedza mumiririri.Ammonia iri nyore kudonha mukugadzira, kufambisa, kuchengetedza uye kushandisa, zvichikonzera kusvibiswa kwakakomba kune nharaunda yemhepo.
Naizvozvo, indasitiri yesamende iripo ikozvino yakatarisana nedambudziko rakati rinopesana.Kushandiswa kweammonia denitration kunogona kuderedza nitrogen oxide emissions, asi dambudziko re "ammonia kupukunyuka" rakaoma kugadzirisa.Uyezve, kugadzirwa kweammonia pachayo inzira yekushandiswa kwesimba rakawanda uye kusvibiswa kwakanyanya, uye kutakura, kuchengetedza uye kushandiswa kuchakonzerawo "ammonia kupukunyuka".
Zvichienderana nezvinetso zvakadaro, mabhizinesi esimende anofanirwa kusimbisa manejimendi ekutakura ammonia uye kuchengetedza, kuvandudza mashandisiro eammonia uye kuderedza "ammonia kupukunyuka".
Amoniya Ichapukunyuka Kubva Kupi?
Pasi pemamiriro ezvinhu ekuchengetedza kwezvakatipoteredza, kuderedza kusvibiswa kwekusvibiswa kwemabhizinesi esimende chinhu chisingadzivisiki chemamiriro ekunze;Panguva imwecheteyo, nekudzokororwa kwe tekinoroji yeindasitiri yesimende, kuderera kwesimba rekushandisa uye emission zviyero zvakare maitiro asingadzivisike ekusimudzira indasitiri.
Kune mabhizinesi esimende, kubva pamaonero ehupfumi, mutengo wekushandura weSCR tekinoroji chete unotarisirwa kuve unodarika mamirioni makumi matatu.Mukuwedzera, mutengo we catalyst wakakwira zvakanyanya kupfuura we "SNCR + sosi kurapwa".Chechipiri, pahwaro hwekupisa kwenitrogen yakaderera uye kupfuta kwakamisikidzwa, kwakasanganiswa neSNCR, mamwe mabhizinesi anogona zvakare kusangana neazvino NOx emission miyero pasi pemamiriro emoto akagadzikana.
Zvichienderana nezvikonzero zviri pamusoro, parizvino, mazhinji emabhizinesi esimende epamba anosarudza nzira ye "SNCR + sosi kurapwa" kuti isangane nezvinodiwa zvekudzikisa ammonia oxide emission, asi iyo inokonzeresa yakashata ndeyekuti dambudziko rekupukunyuka kweammonia rinogona kuwedzera.
