Mu rwego rwo kwerekana gazi ya flue, Guangdong GRVNES ishinzwe kurengera ibidukikije ikora ibijyanye n’ibidukikije, Ltd yateguye ibice 3 + 1 kandi yongeramo urwego rw’ibikoresho byo guhunga amoniya kugira ngo bikemure ikibazo cyo guhunga amoniya igihe amoniya yarangije guterwa, ku buryo birangiye ammonia yatewe irashobora gusohoka mu kirere nyuma yo gukora nyuma yo gukora.
Umuti wo guhunga ammonia uva muri GRVNES flue gaz icyarimwe kuvura icyarimwe ammonia guhunga hamwe na ASC ammonia guhunga

Ukurikije ibisabwa n’umushinga n’ibihe byangiza ikirere, kurengera ibidukikije mu kibaya cya Green Valley byagennye inzira ya tekinike ya "SCR + ASC" kugira ngo yujuje ibisabwa n’umushinga.Inzira ya tekiniki yumushinga irerekanwa ku gishushanyo gikurikira:
SCR + ASC
Igishushanyo mbonera cya SCR + ASC
Igiciro cyo kongeramo azote (NOx) kuri moteri buri gihe gishobora kugabanuka hejuru ya 90% hifashishijwe ikoranabuhanga ryo kugabanya catalitiki, kandi igiciro cyiza cyibintu bya azote (NOx) gishobora kugabanuka hejuru ya 5% hifashishijwe ikoranabuhanga ryo kugabanya catalitiki .Kandi umuvuduko winyuma ni muke, kandi ntanubwo kwiyongera k'umuvuduko winyuma mugikorwa cyo gukoresha.

Ihame ry'akazi rya ASC Ammonia Guhunga Catalizator:
ASC oxydeire ya ASC igizwe ahanini nubwikorezi hamwe na catalitike.Nibikoresho bya moteri ya mazutu.Intego nyamukuru yiki gikoresho ni uguha okiside NH3 irenze muri sisitemu ya mazutu ya mazutu hamwe na O2 kugirango habeho N2 itagira umwanda n’amazi ava muri moteri, kugirango tumenye imyuka ihumanya ya mazutu.Irashobora gukoreshwa ifatanije na mazutu ifata hamwe na catisale yo kweza.
Ubushuhe Ubushuhe
Nukuvuga, ubushyuhe aho catalizator igera kuri 50% ihinduka neza.Ubushyuhe bwo gutwika ASC ammonia guhunga ni 250 ℃.Kugirango ugere ku ihinduka ryinshi, ubushyuhe bwa moteri bugomba kuba hejuru.
Ifishi yo gupakira
Irashobora gutwikirwa ukwayo cyangwa igashyirwa hamwe na SCR, ishobora kuzuza ibisabwa kugirango serivisi itangwe neza.
Ibipimo byangiza ikirere:
Igipimo cyo guhunga Amoniya ≤ 3ppm
Kugabanya imyuka ihumanya ikirere vs kwanduza amoniya mu nganda za sima
Kubera ko ubushakashatsi bwakozwe kuri sisitemu yo gucana itanura rya sima buracyari muburyo bwagutse, haracyari ibitagenda neza mubikorwa byakazi mu itanura hamwe nuburyo bwo gukora oxyde ya azote mu nganda za sima zo murugo.Hariho amasoko menshi ya azote ya azote nibintu byinshi bigira ingaruka.Mu rwego rwa tekinoroji yo kugabanya imyuka ya azote, tekinoroji nyamukuru iriho harimo SCR, SNCR, gutwikwa hamwe nibindi.
SCR yatoranije kugabanya catalitiki yo kugabanya ni tekinoroji nyamukuru yo kwamagana kwisi.Hamwe na ammonia cyangwa urea nkumukozi wa denitration hamwe na catalitike yo gutoranya kwinjizwa mu gikorwa cya catalizator mu munara winjira, igipimo cyo guta agaciro gishobora kugera kuri 90%.
Ikoranabuhanga rya SNCR rikoresha umwanya wubushyuhe bukwiye (900 ℃ ~ 1100 ℃) mu itanura ryangirika kugirango rishyiremo imvange ya amoniya.Kuri ubu bushyuhe, ammonia (NH3) ikorana na NOx muri gaze ya flue kugirango itange N2 na H2O.Igipimo cyo guta agaciro muri rusange ni 40% - 60%, gukoresha ammonia ni nini, kandi igipimo cyo guhunga NH3 ni kinini, gishobora kuba inshuro zirenga 3 za SCR.
Kugeza ubu, inganda za sima zo murugo zarangije ahanini kubaka inyubako ya SNCR.Iri koranabuhanga rikoresha ammonia nyinshi nka NOx igabanya agent.Amoniya iroroshye kumeneka mugikorwa cyo gukora, gutwara, kubika no gukoresha, bikaviramo umwanda mwinshi kubidukikije.
Kubwibyo, inganda za sima ziriho ubu zihura nikibazo kivuguruzanya.Gukoresha ammonia birashobora kugabanya imyuka ya azote, ariko ikibazo cyo "guhunga amoniya" kiragoye kugikemura.Byongeye kandi, umusaruro wa ammonia ubwayo ni inzira yo gukoresha ingufu nyinshi n’umwanda mwinshi, kandi gutwara, kubika no gukoresha nabyo bizatera "guhunga amoniya".
Hashingiwe kuri ibyo bibazo, inganda za sima zigomba gushimangira imicungire y’ubwikorezi no kubika amoniya, kunoza imikoreshereze ya amoniya no kugabanya "guhunga amoniya".
Amoniya izahungira he?
Muri iki gihe cyo kurengera ibidukikije muri iki gihe, kugabanya imyuka ihumanya y’inganda za sima ni byanze bikunze ibidukikije biva hanze;Muri icyo gihe, hamwe no gusubiramo ikoranabuhanga mu nganda za sima, gukoresha ingufu nkeya hamwe n’ibipimo byangiza ikirere nabyo byanze bikunze kuzamura inganda.
Ku mishinga ya sima, ukurikije ubukungu, igiciro cyo guhindura ikoranabuhanga rya SCR cyonyine giteganijwe kurenga miliyoni 30.Mubyongeyeho, ikiguzi cya catalizator kiri hejuru cyane kuruta "SNCR + ivura isoko".Icya kabiri, hashingiwe ku gutwika kwa azote nkeya no gutwikwa, hamwe na SNCR, ibigo bimwe na bimwe birashobora kandi kuba byujuje ubuziranenge bw’imyuka ihumanya ikirere mu gihe cy’itanura rihamye.
Hashingiwe ku mpamvu zavuzwe haruguru, kuri ubu, inganda nyinshi za sima zo mu rugo zihitamo inzira ya "SNCR + ivura isoko" kugira ngo zuzuze ibisabwa byo kugabanya imyuka ihumanya ikirere, ariko ingaruka zavuyemo ni uko ikibazo cyo guhunga amoniya gishobora kwiyongera.
