Pamene miyezo yotulutsa mpweya m'mafakitale ikukulirakulira padziko lonse lapansi, ogwira ntchito akukumana ndi funso lovuta kwambiri: mumatsimikizira bwanji kuti mbewu yanu ikutsatira malamulo pomwe malire ololedwa ali otsika kwambiri? Yankho ndilo
ultra-low mpweya kuwunika mosalekeza - ukadaulo womwe umakulolani kuyeza kuchuluka kwa mpweya wabwino, mosalekeza, komanso pafupifupi nthawi yeniyeni.
Bukhuli likufotokoza zomwe kuwunika kwa mpweya wochepa kwambiri komwe kumatuluka mosalekeza ndi, chifukwa chake kuli kofunika, momwe kumagwirira ntchito, ndi zomwe muyenera kuziganizira potumiza makina.
Kodi Kuwunika kwa Gasi Wopanda Kutsika Kwambiri Ndi Chiyani?
Kuwunika kwa mpweya wochepa kwambiri kumatanthawuza kuyeza kosalekeza kwa mpweya woipitsidwa ndi mpweya wochokera m'mafakitale, ma boilers, ndi njira zoyatsira, pazigawo zotsika kwambiri zomwe zimafunidwa ndi malamulo amakono a chilengedwe.
Mawu akuti "utsi wochepa kwambiri" amafotokoza kuchuluka kwa zoipitsa - nthawi zambiri m'magawo amtundu umodzi pa miliyoni (ppm) kapena magawo pa biliyoni (ppb) - zomwe mbewu m'maiko ambiri ziyenera kukumana nazo. Kuyeza molondola pazigawo zotsikazi kumafuna zambiri kuposa kusanthula koyambira; zimafuna odzipereka Continuous Emission monitoring System (CEMS) opangidwa ndi chidwi chokwanira, kukhazikika, ndi kuwongolera kosokoneza.
Mwachidziwitso, makinawa amayesa gasi wa flue kuchokera pamtengowo, amayesa zoipitsa zazikulu mosalekeza, amalemba zomwe zalembedwazo, ndipo nthawi zambiri amazitumiza kwa oyang'anira kapena malo owongolera kuti afotokozere malamulowo.
Chifukwa Chake Kuwunika Kuwunika kwa Ma Ultra-Low Emissions Kufunika
Pali madalaivala akuluakulu awiri omwe akuthandizira kukula kwaukadaulo uwu:
- Kutsata malamulo. Madera ambiri akhazikitsa malire oletsa kutulutsa kwa nitrogen oxides (NOx), sulfure dioxide (SO2), particulate matter, ndi carbon monoxide. Othandizira akuyenera kuwonetsa kuti akutsatira njira zoyezera modalirika, mosalekeza - osati kuyesa kamodzi kokha.
- Udindo wa chilengedwe ndi mbiri. Kuwunika kolondola kumathandizira kuwongolera kuyaka bwino, kutsika kwamafuta, komanso kuyeretsa bwino, komwe kumakhudza madera, makasitomala, ndi osunga ndalama.
Kupitilira kutsata, kuwunika kosalekeza kumathandizira mainjiniya kukhathamiritsa kuyaka bwino, kuzindikira zolakwika msanga, ndi kuchepetsa ndalama zogwirira ntchito.
Kodi Kuwunika kwa Gasi Wotsika Kwambiri Kumagwira Ntchito Motani?
Njira yowunikira mosalekeza ya gasi imapangidwa kuchokera kumagulu angapo ogwirizana:
| Chigawo | Udindo |
| Sampuli dongosolo | Amatulutsa chitsanzo cha mpweya woyimilira pamtengo ndikuchiyika (kusefera, kuyanika, kuwongolera kutentha). |
| Ma analyzer a gasi | Yezerani kuchuluka kwa zoipitsa pogwiritsa ntchito miyeso yodzipereka. |
| Dongosolo lopezera deta | Amalemba zowerengera, amawerengera ma avareji ndi kuchuluka komwe amatulutsa, ndikusunga zidziwitso kuti apereke lipoti. |
| Calibration / kutsimikizira | Kufufuza pafupipafupi kwa zero ndi span kumatsimikizira kuti ma analyzer amakhalabe olondola pakapita nthawi. |
Njira ziwiri zazikuluzikulu za zitsanzo ndizofala:
- Kuwunika kowonjezera (in-situ kapena dilution). - chitsanzo chimatengedwa kuchokera pamtengo ndikutumizidwa ku analyzer kuti chiyezedwe. Izi zimagwiritsidwa ntchito kwambiri popanga ndende zotsika kwambiri chifukwa zimalola kukhazikika bwino komanso kusanja.
- In-situ / cross-duct monitoring - osanthula amayezera mkati kapena kudutsa muluwo, nthawi zambiri amagwiritsa ntchito njira zowonera. Izi zimapereka kuyankha mwachangu ndi kusanja kwachitsanzo kochepa.
Zosankha zimatengera mtundu wa gasi, kuchuluka kwa momwe amawukira, malo osungira, komanso malo osamalira pamalo aliwonse.
Ndi Zinthu Ziti Zowononga Zomwe Zimayezedwa?
Dongosolo loyang'anira kuchuluka kwa mpweya wochepa kwambiri nthawi zambiri limatsata magawo angapo:
| Parameter | Chifukwa chake imayang'aniridwa |
| NOx (nitrogen oxides) | Chiwopsezo choyambirira choyendetsedwa ndi kuyaka komanso chothandizira kumvula ya utsi ndi asidi. |
| SO2 (sulfure dioxide) | Zopangidwa kuchokera kumafuta okhala ndi sulfure; zoyendetsedwa mwamphamvu m'mafakitale ambiri. |
| CO (carbon monoxide) | Chizindikiro cha kuyaka kosakwanira komanso chizindikiro chachitetezo ndi magwiridwe antchito. |
| Fumbi / zinthu | Tizilombo tolimba mu gasi wa flue; malinga ndi malire okhwima a misa. |
| O2 (oxygen) | Amagwiritsidwa ntchito kukonza zowerengera ndikuwunika mphamvu zoyatsira. |
| CO2 | Zofunikira kwambiri pakuwerengera kwa gasi wowonjezera kutentha komanso kusanthula kwachangu. |
Mndandanda wazomwe zimayendetsedwa zimasiyana malinga ndi dziko, mtundu wamafuta, ndi gawo lamakampani, motero zofunikira ziyenera kutsimikiziridwa ndi malamulo aderalo pakuyika kulikonse.
Measurement Technologies for Ultra-Low Concentrations
Kufikira kuwerengera kodalirika pazigawo zotsika kwambiri kumafuna osanthula omwe ali ndi chidwi chachikulu komanso kusokoneza kochepa. Njira zodziwika bwino ndi izi:
- Non-dispersive infrared (NDIR) - amagwiritsidwa ntchito kwambiri poyezera CO, CO2, ndi SO2.
- Chemiluminescence - njira yokhazikika ya NOx pamiyeso yotsika.
- UV / DOAS (mawonekedwe osiyana optical mayamwidwe) - yothandiza pa NOx yotsika, SO2, ndi mipweya ina yokhala ndi mayamwidwe a UV.
- Ma analyzer a Laser-based (TDLAS). - perekani kuyankha mwachangu komanso kusuntha pang'ono, komwe kumagwiritsidwa ntchito kwambiri pakuyezera kocheperako.
- Beta-ray kapena triboelectric fumbi mita - zofala pakuwunika kosalekeza kwa zinthu.
Ukadaulo woyenera umadalira pa gasi womwe akufuna, kuchuluka kwake komwe amayembekezeredwa, komanso kusokoneza komwe kulipo mumtundu wina wa gasi wa flue.
Mfundo Zofunika Kwambiri Potumiza Dongosolo
Kuyika makina owunikira kuti azitha kutulutsa mpweya wochepa kwambiri kumaphatikizapo zambiri kuposa kugula makina osanthula. Kuti mupeze zodalirika, zotetezedwa, tcherani khutu ku:
- Kufananiza analyzer ndi osiyanasiyana. Chowunikira chomwe chimakhala chochulukira kwambiri kuti chikhale chotsika kwambiri sichidzapereka kulondola komwe mukufuna.
- Zitsanzo zowongolera khalidwe. Pazochepa kwambiri, chinyezi, kutentha, ndi zowonongeka mu chitsanzo zimatha kusokoneza kuwerenga; dongosolo lachitsanzo lopangidwa bwino ndilofunika kwambiri.
- Kuwongolera kosokoneza. Mipweya ina yomwe imapezeka mu mpweya wa flue imatha kusokoneza muyeso; sankhani ma analyzer okhala ndi zovomerezeka zosokoneza.
- Kuwongolera mwachizolowezi. Kuwunika kwa ziro pafupipafupi ndikofunikira kuti musunge zolondola ndikukwaniritsa zoyembekeza zowunikira.
- Kukhulupirika kwa data ndi malipoti. Dongosolo lokhazikika lopeza deta limatsimikizira kuti zolembedwazo zatha, zosindikizidwa nthawi, ndikukonzekera kuwunikiranso owongolera.
Maupangiri Othandizira Pamachitidwe Opitilira Kuwunika
- Sinthani ma analyzer pa ndandanda yofunikira ndi ntchito yanu ndi malamulo.
- Yang'anani ndikuyeretsa zofufuza ndi zosefera pafupipafupi.
- Yang'anirani zitsanzo zamachitidwe opangira ma blockages kapena condensation.
- Tsatirani kusuntha kwa analyzer ndikuyankha ikayandikira kulekerera kovomerezeka.
- Sungani zotsalira za zinthu monga zosefera ndi mpweya wa calibration pamanja.
Mafunso Ofunsidwa Kawirikawiri
Kodi pali kusiyana kotani pakati pa kuwunika kwa gasi wa flue ndi CEMS? Kuyang'anira gasi wa flue ndi mchitidwe wamba woyezera kuchuluka kwa mpweya. CEMS (njira yowunikira mosalekeza) ndi njira yophatikizika, yodzipangira - sampling, analyzer, ndi kupeza deta - yomwe imachita muyesowu mosalekeza kuti izitsatira.
Chifukwa chiyani utsi wotsika kwambiri ndi wovuta kuyeza? Pamalo otsika kwambiri, ma siginecha amakhala ang'onoang'ono, kotero kukhudzidwa kwa analyzer, kukhazikika, komanso kuthekera kowongolera mpweya wosokoneza kumakhala kovuta. Chipangizo chomwe chimagwira ntchito bwino kwambiri mwina sichingakhale cholondola pamilingo yotsika kwambiri.
Kodi kangati kachitidwe koyang'anira gasi wonyezimira iyenera kuyesedwa kangati? Kuchuluka kwa ma calibration kumasiyanasiyana malinga ndi malamulo ndi machitidwe a malo. Makina ambiri amangoyesa zero ndi span tsiku ndi tsiku ndikuwongolera kwathunthu pandandanda yokhazikika yokonza. Nthawi zonse tsatirani zofunikira za mdera lanu.
Kodi dongosolo limodzi lingayang'anire zowononga zambiri? Inde. Machitidwe amakono ambiri amaphatikiza ma analyzer angapo kapena ma analyzer a gasi ambiri kuti ayese magawo angapo (monga NOx, SO2, CO, ndi O2) kuchokera kumtsinje womwewo.
Sankhani Wothandizirana Naye Woyenera Pakuwunika kwa Mafuta a Flue mosalekeza
Kusankha njira yolondola yowunikira mpweya wochepa kwambiri wopitilira muyeso ndi kufananiza chowunikira choyenera ndi masanjidwe amiyeso kumayendedwe anu enieni, momwe mumachulukira, komanso zofunikira pakuwongolera. Ndikoyenera kugwira ntchito ndi wothandizira amene amamvetsetsa luso la kuyeza ndipo angakuthandizeni kupanga dongosolo lomwe limapereka deta yolondola, yotetezedwa.
