Imirongo yubucucike bwa metero ni umukino uhindura denitration mumashanyarazi mugihe cyinganda. Ibipimo byubwenge buhanga byemerera abashoramari gukurikirana ubucucike mugihe nyacyo, nibikoresho byingenzi bikemura ibibazo bya chimique bigoye. Ni ngombwa ko abashoramari bahura n’ibibazo bikora nko kubahiriza amategeko akomeye kandi akomeye y’ibidukikije. Reba mubihe birambuye bakoreramo kugirango bakemure ibibazo byinganda bigoye kandi bakureho imirimo itoroshye ariko isubirwamo.
Amayeri ya Tekiniki Dilemmas muri Denitration
Guhindura imyuka ya azote (NOx) ntabwo ari umurimo woroshye. Okiside ya azote ntishobora kuvaho burundu, hatitawe ku makara yaka, yatwitswe n'amavuta ndetse no mu bimera bya biomass. Gucunga ibyuka bihumanya neza bifitanye isano no kugabanya Catalitike yo kugabanya (SCR) cyangwa kugabanya kutagabanya kugabanuka (SNCR), aho reagent zongerwa mumigezi ya gazi kugirango irusheho kwitwara. Nubwo bimeze bityo ariko, kugenzura neza kugihe gikwiye guhura nibibazo byinshi bivuye mubikorwa bigoye. Kubeshya mubipimo bishobora gutera kunyerera kwa ammonia kandi reagents imyanda.
Igishushanyo mbonera kandi gitanga umusaruro uburebure bwa meterokubipimo byo guhora bibanda kugirango wirinde amakosa yabantu muri sample gakondo. Icyitegererezo cyabantu gishingiye cyane kubigenzura buri gihe no kugereranya bitaziguye. Bene anmetero yubucucike kumurongoishoboye kumenya ihindagurika rito mugukurikirana ubucucike kugirango ifashe guhinduka neza, kugumya inzira zose zerekana ko zihamye kandi neza.
Mubyongeyeho, ikora kandi mugutanga ibipimo byerekana kuvanga ubuziranenge, reagent idahwitse ndetse nigipimo cy umuvuduko. Kurugero, kudahuza imigezi ya urea gushonga mumazi bihagarika chimie reaction. Mugukurikirana ibicucu mu muyoboro, metero yubucucike bwerekana neza ko icyerekezo cyifuzwa gikomeza kubikwa kugeza kubitera inshinge, bikagabanya ingaruka ziterwa n’imikorere idahwitse cyangwa kutubahiriza ibidukikije.
Basabwe gupima ubucucike bwinganda
Gutezimbere Automation muri Denitration na Sisitemu Yizewe
Igihe cyashize abakora inganda bagombaga gushingira kubikorwa byintoki kugirango baterwe neza. Ibipimo bya kijyambere bigezweho byinjiza bidasubirwaho muri sisitemu yo gukwirakwiza igenzura (DCS) cyangwa Programmable Logic Controllers (PLC), itanga ibitekerezo byuzuye byikora. Iyo gusoma ubucucike bitandukanije nurutonde rwateganijwe, sisitemu ihita ihindura umuvuduko wa reagent cyangwa igabanya igisubizo nkuko bikenewe. Uku kwikora ntigabanya gusa umutwaro kubakoresha ahubwo binakuraho gutinda bijyana no gufata ibyemezo byabantu.
Ni ngombwa kuringaniza imigezi yimiti muguhuza desulfurizasi hamwe no gutunganya denitration, aho lime slurry na ammonia ibisubizo bikoreshwa icyarimwe. Kugenzura ubwinshi bwayo mazi yombi nicyo gisabwa kugirango imikorere isanzwe ya desulfurizasi na denitration. Uru rwego rwo guhuza rufasha gukumira ibibazo bisanzwe nko gutembera mu miyoboro ya hekeste cyangwa kurenza urugero rwa amoniya, byombi bishobora kuviramo guhagarara cyangwa kubungabunga amafaranga menshi.
Uretse ibyo, metero ndende irambuye irwanya ibihe bibi mumashanyarazi. Kubishushanyo bidasanzwe kugirango bihangane nubushyuhe bwinshi nigitutu, nibyiza gukoresha imiti yangirika mubihe bigoye nka sisitemu yo kwangiza gaz.
Gushyira mu bikorwa Ubucucike bwa Inline mu makara yaka umuriro
Muri rusange, amashanyarazi akoreshwa n’amakara ahangayikishijwe n’imikorere idahwitse mu gupima ubucucike hamwe n’ibibazo bya tekiniki bifitanye isano bikurikiranye, harimo ariko ntibigarukira gusa ku gufunga imiyoboro, kunyerera kwa amoniya no kubungabunga ibidukikije. Ikibanza cya inline yubucucike nigikoresho cyiza cyubwenge kumurongo wo gutera amoniya hamwe na sisitemu ya hekimone.
Ibisubizo byarahindutse. Kugenzura igihe nyacyo byatumaga igihingwa gihuza neza na reagent ikoreshwa neza kandi itigeze ibaho. Urwego rwo kunyerera rwa Amoniya rwaragabanutse hejuru ya 90%, mugihe kugabanya NOx kurenga 92%. Amabuye ya hekeste, yari yarateje mbere kwipimisha no kuzibira, yagumishijwe ku bucucike bwiza, bivanaho kubungabunga gahunda idateganijwe no kugabanya amasaha 20%. Iterambere ntabwo ryatumye uruganda rwubahiriza ibipimo by’ibidukikije gusa ahubwo rwanagabanije ibiciro by’ibikorwa 15%.
Impamvu Inline Ubucucike Bwingenzi
Igishyiraho umurongo wa metero zingana nubundi buryo bwo gukurikirana ibisubizo ni byinshi kandi bihuza n'imiterere. Ntabwo bagarukira gusa ku kwamagana; ibyifuzo byabo bigera kubikorwa byose byinganda bisaba gucunga neza amazi. Mu rwego rw’amashanyarazi, ibi bikubiyemo sisitemu yo guta amazi, gutunganya amazi mabi, hamwe n’ibikorwa byo kuvanga lisansi. Ubushobozi bwabo bwo gutanga amakuru nyayo, yukuri, kandi akoreshwa atuma baba umusingi wibikorwa bigezweho.
Mugushira mubikorwa ibyo bikoresho, amashanyarazi arashobora kugera kurwego rwo kugenzura ibikorwa bitagerwaho. Inyungu zirenze kubahiriza no gukora neza; zirimo kandi ibikoresho byongerewe igihe kirekire, kugabanya ibiciro byo kubungabunga, hamwe no gukomeza kuramba. Kubakoresha baha agaciro imikorere ninshingano zibidukikije, metero yubucucike ntabwo ishoramari gusa - birakenewe.
Umwanzuro
Iyemezwa rya metero yubucucike muri sisitemu yo kwerekana byerekana uburyo ikoranabuhanga ryateye imbere rishobora guhindura inzira zinganda. Mugukemura ibibazo nka reagent idahwitse, kunyerera kwa ammonia, no gutunganya ibyikora, ibi bikoresho bifasha amashanyarazi gukora neza, birambye, kandi byunguka. Ibyerekanwe byerekana mubikorwa nyabyo byisi bishimangira agaciro kabo nkigikoresho gikomeye mukurwanya imyuka ihumanya ikirere. Niba ushaka kuzamura ibikorwa byawe byo kwamagana, nta gihe cyiza cyo gucukumbura ubushobozi bwo gupima ubucucike.
