Izinzwa zegesi, njengezingxenye eziyinhloko zokubona imvelo nokuqinisekisa ukuphepha, zigxile kakhulu kuzo zonke izingxenye zomphakathi wanamuhla. Izifundo ezilandelayo zamazwe ngamazwe zibonisa ukuthi izinzwa zegesi zidlala kanjani indima ebalulekile ezimbonini, empilweni yasemadolobheni, ekuvikelweni kwemvelo, kanye nasezintweni zikagesi ezisetshenziswa ngabathengi.
Icala 1: I-United States – Ukuqapha Igesi Enobuthi Nevuthayo Ezindaweni Zezimboni
Ingemuva:
Izimboni e-US, njenge-oyela negesi, amakhemikhali, kanye nokukhiqiza, zisebenza ngaphansi kwemithetho eqinile yokuphepha kwezisebenzi kanye nezempilo (isb., amazinga e-OSHA). Ukuqapha okuqhubekayo kubalulekile ezindaweni ezivalekile noma ezivalekile kancane lapho kungase kuvele khona ukuvuza kwamagesi avuthayo noma anobuthi.
Isicelo kanye nesixazululo:
Izinhlelo zokuthola igesi eziqinile kanye nemishini yokubona igesi ephathekayo zisetshenziswa kabanzi ezindaweni zezimboni ezifana nezimboni, izindawo zokuhluza, kanye nezindawo zokuhlanza amanzi amdaka.
- Lawa madivayisi ahlanganisa izinzwa ezithile kumagesi athile, njenge: Izinzwa ze-Electrochemical (zamagesi anobuthi njenge-carbon monoxide ne-hydrogen sulfide), Izinzwa ze-Catalytic bead (zamagesi avuthayo njenge-methane ne-propane), kanye nezinzwa ze-Infrared (ze-carbon dioxide).
- Ama-fixed detector afakwa ezindaweni ezibalulekile zobungozi futhi axhunywe ohlelweni lokulawula oluphakathi. Uma ukugcwala kwegesi kudlula umkhawulo ophephile, aqala ngokushesha ama-alamu azwakalayo nabonakalayo futhi angasebenza ngokuzenzakalelayo izinyathelo zokunciphisa njengokungenisa umoya.
- Izisebenzi kudingeka zisebenzise ama-detector aphathekayo ukuze zingene ngaphambi kokungena kanye nokuqapha okuqhubekayo ngaphambi kokungena ezindaweni ezivalekile.
Imiphumela:
- Kuqinisekisa Ukuphepha Kwabasebenzi: Kuvimbela kakhulu ubuthi babasebenzi, ukufutha, noma izehlakalo zokuqhuma okubangelwa ukuvuza kwegesi.
- Ukuthobela Imithetho: Kusiza izinkampani ukuba zihambisane nemithetho eqinile yokuphepha kanye nempilo emsebenzini, zigweme izinhlawulo ezinkulu kanye nezingozi zomthetho.
- Kuthuthukisa Impendulo Ephuthumayo: Idatha yesikhathi sangempela ivumela amaqembu okuphepha ukuthola ngokushesha umthombo wokuvuza futhi athathe isinyathelo.
Icala 2: I-European Union - Amanethiwekhi Okuqapha Ikhwalithi Yomoya Wasemadolobheni
Ingemuva:
Ngaphansi kwe-Ambient Air Quality Directive ye-EU, amazwe angamalungu kudingeka ukuthi asungule amanethiwekhi okuqapha ikhwalithi yomoya ezindaweni zasemadolobheni ukuze kulungiswe ukungcola okuvela ezimotweni kanye nokukhishwa kwegesi ezimbonini, ikakhulukazi i-PM2.5, i-PM10, i-nitrogen dioxide, kanye ne-ozone.
Isicelo kanye nesixazululo:
Amadolobha amaningi aseYurophu, njengeLondon neParis, asebenzise amanethiwekhi ahlanganisiwe ahlanganisa iziteshi zokuqapha zezinga lokubhekisela kanye nama-node e-micro-sensor angabizi kakhulu.
- Iziteshi zezinga lokubhekisela zisebenzisa abahlaziyi abanokunemba okuphezulu njenge-Optical Particle Counters, i-Chemiluminescence analyzers (ye-nitrogen oxides), kanye ne-UV Absorption analyzers (ye-ozone) ukuze banikeze idatha esemthethweni, evikelekile ngokomthetho.
- Ama-node e-micro-sensor asatshalaliswa kakhulu efenisha yasemgwaqweni, ezigxotsheni zezibani, noma emabhasini, kusetshenziswa izinzwa ze-Metal Oxide Semiconductor (MOS) kanye nezinzwa ze-optical particle ukuze kuhlinzekwe amamephu aphezulu okungcoliswa kwesimo sezulu.
- Idatha evela kulezi zinzwa ihlanganiswe ngamapulatifomu e-IoT futhi ishicilelwe emphakathini ngesikhathi sangempela.
Imiphumela:
- Ukumapha Okuningiliziwe Kokungcola: Kusiza ohulumeni nezakhamuzi ukuqonda imithombo, ukusatshalaliswa, kanye nokuguquguquka kokungcola, kusekela ukwenziwa kwezinqumo zemvelo.
- Ikhuthaza Izenzo Zempilo Yomphakathi: I-Real-time Air Quality Index (AQI) ixwayisa amaqembu azwelayo (isib., iziguli ze-asthma) ukuthi athathe izinyathelo zokuzivikela.
- Ihlola Ukusebenza Kwenqubomgomo: Isetshenziselwa ukuhlola umthelela wezinqubomgomo zemvelo njengezindawo ezikhipha umoya ongcolile kanye nemikhawulo yethrafikhi.
Icala 3: IJapani - Ukuphepha Kwegesi Emakhaya Ahlakaniphile Nezakhiweni
Ingemuva:
EJapane, izwe elivame ukuzamazama komhlaba futhi elinabantu abaningi, ukuvimbela imililo nokuqhuma okubangelwa ukuvuza kwegesi kuyinto eza kuqala ekuphepheni kwezindlu nezebhizinisi. Ngaphezu kwalokho, ukukhathazeka ngekhwalithi yomoya wangaphakathi sekuyingxenye yokuphila okunempilo.
Isicelo kanye nesixazululo:
- Ukuphepha Kwegesi: Ukufakwa kwezinzwa zegesi ezivuthayo (ngokuvamile kusetshenziswa ubuchwepheshe be-catalytic bead noma ubuchwepheshe be-semiconductor) kuyimpoqo cishe kuzo zonke izindlu namafulethi aseJapan ukuze kutholakale ukuvuza kwegesi yedolobha noma i-LPG. Ngokuvamile zixhumene nama-valve okuvala igesi okuphuthumayo, okuvimba ngokuzenzakalelayo ukugeleza kwegesi lapho kutholwa.
- Ikhwalithi Yomoya Wangaphakathi: Ezindlini zokuhlala ezisezingeni eliphezulu, emahhovisi nasezikoleni, izinzwa ze-carbon dioxide (ngokuvamile ezisebenzisa ubuchwepheshe be-Non-Dispersive Infrared) zisebenza “njengobuchopho” bezinhlelo zokungenisa umoya. Lapho amazinga aphezulu e-CO₂ etholakala, uhlelo lusebenza ngokuzenzakalelayo ukuze lungenise umoya omusha, lugcine indawo yangaphakathi ikhululekile futhi inempilo.
- Isexwayiso Somlilo: Izitholi zomusi ze-photoelectric zivame ukuhlanganisa izinzwa ze-carbon monoxide ukuze zinikeze izixwayiso zangaphambi kwesikhathi nezinembile zemililo evuthayo.
Imiphumela:
- Ukuphepha Kwasekhaya Okuthuthukisiwe Kakhulu: Kunciphisa kakhulu izingozi ezibangelwa ukuvuza kwegesi.
- Umoya Osebenzisa Amandla Kakhulu: Amasu omoya osebenzisa isidingo anciphisa kakhulu ukusetshenziswa kwamandla esakhiweni uma kuqhathaniswa nokusebenza okuqhubekayo.
- Kudala Izindawo Ezinempilo Zangaphakathi: Kunciphisa ngempumelelo ingozi ye-"Sick Building Syndrome" futhi kuthuthukisa induduzo yabantu abahlala khona kanye nezisebenzi.
Icala 4: IJalimane - Ukuqapha Inqubo Yezimboni Nokukhishwa Kwegesi
Ingemuva:
IJalimane inesizinda esiqinile sezimboni futhi ilandela imithetho eqinile yokukhishwa kwegesi ezimbonini ze-EU. Ukuqapha ngokunembile ukugcwala kwegesi ezinqubweni zezimboni kubalulekile ekwenzeni ngcono ukusebenza kahle kokushisa, ukunciphisa ukusetshenziswa kwamandla, kanye nokuqinisekisa ukukhishwa kwegesi okuhambisanayo.
Isicelo kanye nesixazululo:
- Ukulawulwa Kwenqubo: Ezinqubweni zokushisa (isb., ama-boiler, ama-furnace), izinzwa ze-oxygen ze-zirconia zisetshenziswa ukuqapha okuqukethwe kwe-oxygen kugesi ephumayo ngesikhathi sangempela. Lokhu kuvumela ukulawulwa okunembile kwesilinganiso sikaphethiloli nomoya, ukuqinisekisa ukushisa okuphelele nokonga amandla.
- Ukuqapha Ukukhishwa Kwegesi: Izinhlelo Zokuqapha Ukukhishwa Kwegesi Eziqhubekayo zifakiwe ezinqwabeni zentuthu kanye nasezindleleni zokukhipha umoya. Lezi zinhlelo zihlanganisa abahlaziyi abahlukahlukene abanokunemba okuphezulu, njengezinzwa ze-Non-Dispersive Infrared (ze-CO, CO₂), abahlaziyi be-Chemiluminescence (ze-NOx), kanye nabahlaziyi be-UV Fluorescence (ze-SO₂), ukuze banikeze isilinganiso esingaphazanyiswa kanye nokuqoshwa kwamazinga okungcola ukuze kubikwe ukuhambisana nomthetho.
Imiphumela:
- Ukusebenza Kahle Kagesi Okuthuthukisiwe Nokunciphisa Izindleko: Kunciphisa ngqo ukusetshenziswa kukaphethiloli ngokwenza ngcono inqubo yokushisa.
- Iqinisekisa Ukuthobela Imithetho: Ihlinzeka ngemininingwane enembile nengaguquki yokukhishwa kwegesi, iqinisekisa ukuthi izinkampani ziyahlangabezana nemithethonqubo yemvelo futhi igwema izinhlawulo.
- Isekela Izibopho Zezemvelo: Ihlinzeka ngokusekelwa kwedatha yokubika ngokusimama kwenkampani.
Isiphetho
Kusukela ekuphepheni kwezimboni e-US kuya emoyeni wasemadolobheni e-EU, kanye nasemakhaya ahlakaniphile eJapane kuya ekuthuthukisweni kwezinqubo zezimboni eJalimane, la macala abonisa ngokusobala ukuthi ubuchwepheshe bezinzwa zegesi sebube yitshe lesisekelo lokuqinisekisa ukuphepha komphakathi, ukuvikela impilo yemvelo, ukuthuthukisa ikhwalithi yokuphila, kanye nokufeza ubuhlakani bezimboni kanye nokuguqulwa okuluhlaza. Njengoba ubuchwepheshe be-IoT kanye ne-AI buqhubeka nokuhlangana, izinhlelo zabo zokusebenza zizoba ezihlakaniphe kakhulu futhi zibe khona yonke indawo.
Isethi ephelele yamaseva kanye ne-software engenantambo module, isekela i-RS485 GPRS /4g/WIFI/LORA/LORAWAN
