Mugihe ibipimo by’ibyuka byoherezwa mu nganda bigenda byiyongera ku isi, abashoramari bahura n’ikibazo gikomeye: nigute ushobora kwerekana ko igihingwa cyawe kitubahiriza igihe imipaka yemerewe kuba mike? Igisubizo ni
ultra-low imyuka ihumanya ikomeza gukurikirana gaz ya flue - tekinoroji igufasha gupima ibyuka bihumanya neza, ubudahwema, kandi mugihe nyacyo.
Aka gatabo gasobanura icyo ultra-low imyuka ihumanya ikomeza kugenzura gazi ya flue aricyo, impamvu ifite akamaro, uko ikora, nicyo ugomba gusuzuma mugihe cyohereza sisitemu.
Ni ubuhe buryo bukabije bwohereza imyuka ihumanya ikirere?
Kugenzura imyuka ihumanya ikirere ikomeza kugenzura ibyuka bihumanya ikirere byerekana gupima guhora kwangiza imyuka ihumanya ikirere iva mu nganda zikora inganda, amashyiga, hamwe n’umuriro, ku gipimo gito cyane gisabwa n’amabwiriza y’ibidukikije agezweho.
Ijambo "imyuka ihumanya ikirere" isobanura urwego rwanduye - akenshi mu bice by'imibare imwe kuri miliyoni (ppm) cyangwa ibice kuri miliyari (ppb) - ibihingwa mu bihugu byinshi bigomba guhura nabyo. Gupima neza kuri ibyo bitekerezo bike bisaba ibirenze gusesengura shingiro; bisaba ubwitange sisitemu yo gukurikirana ibyuka bihumanya ikirere (CEMS) byakozwe hamwe na sensibilité ihagije, itajegajega, hamwe no gukosora kwambukiranya.
Mu buryo bufatika, sisitemu ntangarugero isohora gaze iva mukirindiro, igapima umwanda wingenzi ubudahwema, ikandika amakuru, kandi akenshi ikohereza kubashinzwe kugenzura cyangwa icyumba cyo kugenzura kugirango raporo zubahirizwe.
Impamvu Ultra-Ntoya yo Kugenzura Ibyingenzi
Hano haribintu bibiri byingenzi byihishe inyuma yubuhanga bukenewe:
- Kubahiriza amabwiriza. Uturere twinshi twashyizeho imipaka ikabije yo kohereza imyuka ya azote (NOx), dioxyde de sulfure (SO2), ibintu byangiza, na monoxide ya karubone. Abakoresha bagomba kwerekana kubahiriza binyuze mubipimo byizewe, bikomeza - ntabwo ari intoki imwe.
- Inshingano y'ibidukikije n'icyubahiro. Gukurikirana neza bifasha kugenzura neza gutwika, gukoresha lisansi nkeya, nigikorwa kigaragara gisukuye, gifitiye akamaro abaturage, abakiriya, nabashoramari kimwe.
Kurenga kubahiriza, guhora ukurikirana amakuru afasha injeniyeri guhitamo neza gutwika, kumenya amakosa hakiri kare, no kugabanya ibiciro byo gukora.
Nigute imyuka ihumanya ikirere ikomeza gukurikirana imyuka ya gaz ikora?
Sisitemu isanzwe ikurikirana ya gaz ikurikirana yubatswe mubice byinshi bihujwe:
| Ibigize | Uruhare |
| Sisitemu y'icyitegererezo | Gukuramo icyitegererezo cya gaze ihagarariwe mumurongo hamwe nibisabwa (kuyungurura, gukama, kugenzura ubushyuhe). |
| Abasesengura gaz | Gupima imyanda ihumanya ukoresheje amahame yihariye yo gupima. |
| Sisitemu yo gushaka amakuru | Andika ibyasomwe, ubara impuzandengo n'ibisohoka byose, kandi ubike amakuru yo gutanga raporo. |
| Guhindura / kwemeza | Igenzura risanzwe rya zeru na span byemeza ko abasesengura bakomeza kuba ukuri mugihe runaka. |
Uburyo bubiri bwagutse bwo guhitamo ni rusange:
- Gukurikirana (in-situ cyangwa dilution) gukurikirana - icyitegererezo cyakuwe mubirindiro bikajyanwa kubisesengura kugirango bipime. Ibi birakoreshwa cyane mubikorwa bya ultra-low concentration kuberako itanga uburyo bwitondewe hamwe na kalibrasi.
- Gukurikirana-kugenzura / guhuza imiyoboro - abasesengura bapima imbere cyangwa kuruhande, akenshi bakoresheje uburyo bwiza. Ibi bitanga igisubizo cyihuse hamwe nicyitegererezo gike.
Guhitamo biterwa nubwoko bwa gaze, urwego rwimiterere, imiterere yimiterere, hamwe nibidukikije kuri buri kibanza.
Ni ibiki bihumanya byapimwe?
Sisitemu yo gukurikirana ibyuka bihumanya ikirere ikurikirana ibintu byinshi byingenzi:
| Parameter | Impamvu ikurikiranwa |
| NOx (okiside ya azote) | Ikintu cyambere cyateganijwe gutwika umwanda nuwagira uruhare mu mvura yumwotsi na aside. |
| SO2 (dioxyde de sulfure) | Biva mu bicanwa bitwara sulfure; kugenzurwa cyane mu nganda nyinshi. |
| CO (monoxide ya karubone) | Ikimenyetso cyo gutwikwa kutuzuye hamwe nikimenyetso cyumutekano nubushobozi. |
| Ikintu cyihariye / umukungugu | Ibice bikomeye muri gaze ya flue; hashingiwe ku mbibi zikomeye zo kwibandaho. |
| O2 (ogisijeni) | Byakoreshejwe mugukosora ibyasomwe no gusuzuma imikorere yaka. |
| CO2 | Kwiyongera cyane kubijyanye na comptabilite-gaze no gusesengura neza. |
Urutonde rwihariye rwibipimo byateganijwe biratandukana bitewe nigihugu, ubwoko bwa lisansi, ninganda zinganda, bityo ibisabwa bigomba kwemezwa kubirwanya amabwiriza akurikizwa kuri buri gikoresho.
Ikoreshwa rya tekinoroji ya Ultra-Ntoya
Kugera kubisomwa byizewe kumurongo muke cyane bisaba abasesengura bafite sensibilité yo hejuru hamwe no kwivanga kwinshi. Ubuhanga busanzwe burimo:
- Imirasire idatatanye (NDIR) - ikoreshwa cyane mugupima CO, CO2, na SO2.
- Chemiluminescence - tekinike isanzwe ya NOx kuri concentration nke.
- UV / DOAS (itandukaniro ritandukanye rya optique yo kwinjiza spekitroscopi) - ikora neza kurwego rwo hasi NOx, SO2, nizindi myuka hamwe na bande ya UV.
- Abasesenguzi ba Laser (TDLAS) - tanga igisubizo cyihuse hamwe na drift ntoya, igenda ikoreshwa mugupima-kwibanda cyane.
- Beta-ray cyangwa metero yumukungugu wa triboelectric - ibisanzwe kubikurikirana bikurikirana.
Ikoranabuhanga ryiza riterwa na gaze igenewe, igipimo cyayo giteganijwe, hamwe nimbogamizi igaragara muri materique yihariye.
Ibitekerezo Byingenzi Iyo Kohereza Sisitemu
Gushiraho sisitemu yo kugenzura ibyuka bihumanya ikirere bikubiyemo ibirenze kugura isesengura. Kugirango ubone amakuru yizewe, yiregura, witondere:
- Guhuza nisesengura kurwego. Isesengura rirenze urugero kuri ultra-low concentration ntizatanga ukuri ukeneye.
- Icyitegererezo cyiza. Mugihe gito, ubushuhe, ubushyuhe, nibihumanya murugero birashobora kugoreka gusoma; sisitemu yateguwe neza ni ngombwa.
- Igenzura ryambukiranya imipaka. Indi myuka iboneka muri gaze ya flue irashobora kubangamira gupima; hitamo abasesengura bafite ibyemezo byo kwivanga byagaragaye.
- Guhindura gahunda. Kugenzura zeru na span buri gihe ni ngombwa kugirango ubungabunge ukuri kandi uhuze ibyifuzo byubugenzuzi.
- Ubusugire bwamakuru no gutanga raporo. Sisitemu ikomeye yo gukusanya amakuru yemeza ko inyandiko zuzuye, zashyizweho kashe, kandi ziteguye gusubirwamo.
Inama zo Kubungabunga Sisitemu Zikurikirana
- Hindura abasesengura kuri gahunda isabwa nigikorwa cyawe.
- Kugenzura no guhanagura icyitegererezo hamwe na filteri buri gihe.
- Kurikirana icyitegererezo cya sisitemu yo guhagarika cyangwa guhuza.
- Kurikirana analyseur drift hanyuma usubize iyo yegereye kwihanganira byemewe.
- Gumana ibikoresho bikoreshwa nka filtri na gaze ya kalibrasi ku ntoki.
Ibibazo Bikunze Kubazwa
Ni irihe tandukaniro riri hagati yo gukurikirana gazi ya flu na CEMS? Gukurikirana gaz ya flux nigikorwa rusange cyo gupima ibyuka bihumanya. CEMS (sisitemu yo gukurikirana ibyuka bihumanya ikirere) ni sisitemu ihuriweho, yikora - icyitegererezo, isesengura, hamwe no kubona amakuru - ikora iki gipimo ubudahwema hagamijwe kubahiriza.
Kuki ibyuka bihumanya ikirere bigoye kubipima? Mugihe gito cyane, ibimenyetso ni bito, kubwibyo gusesengura ibyiyumvo, gushikama, hamwe nubushobozi bwo gukosora kubangamira imyuka biba ingirakamaro. Igikoresho gikora neza murwego rwo hejuru gishobora gusa kuba kidahwitse bihagije kurwego rwo hejuru.
Ni kangahe sisitemu yo gukurikirana gaz ya flue igomba guhinduka? Calibration frequency ihindagurika ukurikije amabwiriza hamwe nimyitozo yurubuga. Sisitemu nyinshi ikoresha zeru na span igenzura buri munsi kandi ikora kalibrasi yuzuye kuri gahunda yagenwe yo kubungabunga. Buri gihe ukurikize ibisabwa byaho bikenewe.
Sisitemu imwe irashobora gukurikirana imyanda myinshi? Yego. Sisitemu nyinshi zigezweho zihuza abasesengura benshi cyangwa abasesengura gazi nyinshi kugirango bapime ibipimo byinshi (nka NOx, SO2, CO, na O2) uhereye kumugezi umwe.
Hitamo Umufatanyabikorwa Ukwiye Gukurikirana Amazi Yumuriro
Guhitamo ibyuka bihumanya ikirere bihoraho bikurikirana sisitemu yo kugenzura imyuka ya gazi ni bijyanye no guhuza neza isesengura ryiza hamwe nicyitegererezo cyibikorwa byawe byihariye, imiterere ya stack, nibisabwa n'amategeko. Birakwiye gukorana nuwabitanze yumva tekinoroji yo gupima kandi ashobora kugufasha gukora sisitemu itanga amakuru yukuri, yiregura.
