Denitration ntchito Mpweya umene denitration luso

Mankhwalawa denitrification chitachitidwa ntchito zobwera chifukwa cha okosijeni denitrification luso mamolekyulu yogwira (Mpweya umene) kukwaniritsa chandamale cha NOx mfundo umuna. Pa nthawi yomweyo, zinthu kumamukopa ndende mpweya, kuzirala madzi kutentha ndi kusintha kukatentha katundu anali kusanthula kale. Zotsatira zake zinasonyeza kuti pamene kumamatira kuthamanga ndi desorption kuthamanga kwa VPSA mpweya jenereta anali 40-48 kPa ndi -45-55 kPa, ndende mpweya anafika mtengo mulingo woyenera kwambiri pa 92%. Yozizira madzi kutentha sayenera upambana 32 ° C. Pa nthawi yomweyo, iwo akufuna kuti umuna NOx nthawi zonse zoletsedwa ndi ulamuliro kachulukidwe wa benchi kukakomana ndi kusintha kukatentha katundu.

Ndi m'chilengezo za "ndondomeko Kupewa ndi Control wa Atmospheric lowononga mpweya" ndi kuchepetsa winanso wa umuna wa zoipitsa mpweya flue ku malasha amapanga boilers, ulamuliro wa nitrogen oxide NOx wakhala patsogolo. SCR panopa ngati luso denitrification ndi zothandiza kwambiri kuchotsa dzuwa. Komabe, pamene n'cholinga a m'munsi umuna NOx, luso uyu adzachititsa kwambiri amoniya Pepala chifukwa kusanganikirana ake chibadidwe ndi nthenda yotaya munda m'goli. Pa nthawi yomweyo, monga chothandizira potsegula ukuwonjezeka, mlingo kutembenuka kwa SO2 kuti kuchuluka SO3, ndi utsi komaliza Kuwonjezeka kwa anthu ambiri NH3 ndi SO3 mu mpweya zidzalimbikitsa kukulitsa ndi jamming wa preheater mpweya. The zobwera chifukwa cha okosijeni denitrification luso zochokera otsika kutentha mamolekyulu yogwira zabwino kwambiri kupewa mavuto pamwamba. Wosiyana SCRs, mamolekyulu yogwira (monga O3) ndi njira mankhwala synergistic mpweya flue mwa makutidwe ndi okosijeni wa zoipitsa monga NO ndi zitsulo zolemera. Zimenezi ziribe kanthu kochita ndi mtundu wa kukatentha, chinthu chithandizo ndi mchira mpweya wa kukatentha, ndi makutidwe ndi okosijeni wa NO ndi zitsulo mu mpweya flue kwa mkulu-mtengo NOx ndi zitsulo oxides, ndiyeno mgwirizano zoipitsa monga NOx, SO2, ndi zitsulo. Chotsani.

Mu pepala ili, yogwira zobwera chifukwa cha okosijeni luso denitration anamugwiritsa kuphunzira NOx umuna kulamulira mu malasha amapanga flue mpweya, ndi zinthu zokhudza denitration Mwachangu monga ndende mpweya, yozizira kutentha madzi ndi kusintha kukatentha katundu anali kusanthula kale.

1, kusintha pulogalamu

The kukatentha choyambirira cha amagetsi ndi akanema 2 35t / h ndi 1 ya 50t / h unyolo ng'anjo. The original yonyowa desulfurization dongosolo amagwiritsa ya laimu gypsum njira SO2 kuchotsa. The yogwira maselo zobwera chifukwa cha okosijeni denitration luso umagwiritsidwa ntchito mchira flue pambuyo flue mpweya confluence. Choncho okha flue mlingo mpweya otaya ndi nitrogen oxide zili ndi mchira flue ayenera kuganizira, amene zimadalira pa kuyaka akafuna kukatentha kwambiri. Kugwiritsa choyambirira zipangizo desulfurization okha choyambirira flue mpweya desulfurization nsanja polowera flue anali kusinthidwa ndi yogwira maselo riyakitala anakhazikitsidwa. Onse a kusinthika ndi zipangizo zatsopano monga tikuonera Chithunzi 1. dongosolo oxygen, yogwira dongosolo maselo, yozizira dongosolo madzi ndi magetsi ndi chida kulamulira machitidwe wothandiza. Kachitidwe mpweya amagwiritsa ntchito adsorbent kupatukana mpweya ndi asafe mu mlengalenga ndi kumamatira ndi desorption kutulutsa ndende apamwamba a oxygen. Pambuyo pressurization, deoiling, ndipo fumbi kuchotsa, mpweya akulowa yogwira jenereta maselo, ndipo potsiriza molekyulu yogwira (O3) ndi kwaiye kudzera kumaliseche tsankho m'chipinda kumaliseche. The kumaliseche magetsi mkulu-voteji kwa mpweya m'chipinda kumaliseche amapanga wambirimbiri kutentha, kotero madzi kunja kuzirala chofunika kuti kutenthetsa-kuchitira kumaliseche chipinda kuonjezera ndende ya molekyulu yogwira (O3).
