Izintambo ezibamba ilangabi: Onogada abangabonakali abavikela umphakathi wanamuhla

Ehlathini lensimbi lezakhiwo zesimanje nezindawo zezimboni, izintambo ezingenakubalwa zixhumene kakhulu njengohlelo lwezinzwa lomzimba womuntu. Lapho umlilo efulethini eliphakeme eDubai ngo-2022 ubangela ukusabalala kwezintambo ezivamile, onjiniyela emhlabeni wonke baphinde bagxila kubuchwepheshe bezintambo ezivimbela ilangabi. Ingozi eyabangela amashumi ezigidi zamaRandi iveze iqiniso elinonya: lapho kubhekene nemililo, izintambo ezivamile zivame ukuba ama-fuse abulalayo. Izintambo ezivimbela umlilo ziwubuchwepheshe obuyinhloko emkhakheni wokuphepha kagesi, futhi ukubaluleka kwazo akungaphansi komklamo womlilo wezakhiwo zokwakha. Le ntambo ekhethekile ingagcina isakhiwo esiphelele emalangabini, inciphise ngempumelelo ukusabalala komlilo, futhi ilwele isikhathi esiyigugu sokususwa kwabasebenzi kanye nokuhlenga umlilo. "Kuyindlela yokuphila" ebalulekile ohlelweni lokuvikela ukuphepha lwesimanje. Emkhakheni wezakhiwo eziphakeme kakhulu, ukusetshenziswa kwezintambo ezivimbela ilangabi kuhlobene ngqo nekhono lokuvimbela nokulawula inhlekelele. Ohlelweni lokunikezwa kwamandla eShanghai Central Building, zonke izintambo eziqondile zisebenzisa indinganiso ye-Class B1 evimbela ilangabi, futhi ikhebula ngalinye lemitha liqukethe okungaphezu kwama-300g okugcwala okuvimbe umlilo okungaphili. Lo mklamo uvumela i-cable shaft enezitezi ezingu-20 ukuthi isakaze isivinini sokusabalala komlilo ku-1/5 yesakhiwo esivamile ekuhlolweni komlilo okulingisiwe. Ikhebula le-optical elivimbela umlilo elisetshenziswa esakhiweni esihlakaniphile, izinto zalo ezikhethekile ze-sheath lizophopha futhi likhule lapho livutha, lenze ungqimba lokuvikela ukushisa olunobubanzi obuphindwe kathathu kunobukhulu bokuqala, livikele ngempumelelo i-optical fiber yangaphakathi ekulimaleni. Uhlelo lokuhamba ngesitimela lunezidingo eziqinile zokusebenza kwezintambo ezivimbela umlilo. Ikhebula elivimbela umlilo elisetshenziswa emhubheni wesitimela kumele liqinisekiswe yi-HL3 ngokwezinga le-EN 45545-2, okusho ukuthi lapho ikhebula lishiswa elangeni elingu-800 °C, ubuningi bomusi abudluli ku-0.5m²/s ngomzuzu. I-Siemens, eJalimane, yakha ngokukhethekile ikhebula elivimbela umlilo elikhethekile lesitimela saseMunich. Yamukela isakhiwo sokugoqa ibhande le-mica elinezingqimba ezimbili. Ekuhlolweni kokushisa, ukuhanjiswa kokukhanya kwegesi ye-flue bekulokhu kungaphezu kuka-80%, okuthuthukisa kakhulu ukubonakala endaweni yomhubhe.
