Pakupanga ma electrode a graphite, mavuto okhudzana ndi kugwiritsa ntchito mphamvu amatha kuthetsedwa pogwiritsa ntchito njira zonse, kuphatikizapo kukonza kayendedwe ka njira, kukulitsa kugwiritsa ntchito mphamvu moyenera, kulimbitsa kasamalidwe ka zida, komanso kugwiritsa ntchito ukadaulo wosunga mphamvu. Mayankho enieni ndi awa:
I. Kukonza Njira Zophikira ndi Kuphika Zinthu Zopanda Chidutswa
Kukonzekera Zinthu Zopangira ...
Pa nthawi ya calcination, kuwongolera kutentha (1,250-1,350°C) ndi nthawi yake kumachepetsa kusinthasintha kwa kutentha, kumathandizira kukhazikika kwa kutentha kwa zinthu zopangira, komanso kumachepetsa kugwiritsa ntchito mphamvu yophikira pambuyo pake. Mwachitsanzo, kusintha ng'anjo zachikhalidwe ndi ma microwave ozungulira kapena ng'anjo zamagetsi kungathandize kuti kutentha kugwire bwino ntchito ndi 10%-15%.
Mu kuphika, kuphika kwachiwiri kapena kuyikamo zinthu zingapo (monga kuyikamo zinthu zitatu ndi kuyikamo zinthu zinayi) kumadzaza ma pores, kuchepetsa ma porosity a zinthu zomalizidwa, ndikuwonjezera kuchuluka kwa zinthu ndi mphamvu ya makina, motero kumachepetsa kugwiritsa ntchito mphamvu kwa chinthucho.
Kukonza Njira Yopangira Impregnation
Mu gawo loyikamo, kukonza mphamvu ya phula (1.2-1.5 MPa) ndi kutentha (180-200°C) kumawonjezera kuchuluka kwa kulemera kwa phula (≥14% pa phula loyamba ndi ≥9% pa phula lachiwiri), kuchepetsa kuchuluka kwa kuphika mobwerezabwereza ndikuchepetsa kugwiritsa ntchito mphamvu mwanjira ina.
II. Kukweza Ukadaulo Wothandizira Kujambula Zithunzi
Kukonza Kutentha Kwambiri
Pa nthawi yogwiritsira ntchito graphitization, kusintha ng'anjo zachikhalidwe za Acheson ndi ng'anjo zolumikizidwa ndi kutentha kwamkati (LWG) kumafupikitsa nthawi yogwiritsira ntchito mphamvu (maola 9-15 a ng'anjo za LWG poyerekeza ndi maola 50-80 a ng'anjo za Acheson) ndipo kumachepetsa kugwiritsa ntchito magetsi ndi 30%-50%.
Kuwongolera bwino kutentha kwa graphitization (2,300-3,000°C) kumapewa kutaya mphamvu kuchokera ku kutentha kwambiri pamene kuonetsetsa kuti kapangidwe ka kaboni kakusintha kukhala makristaro a graphite okhala ndi magawo atatu, zomwe zimapangitsa kuti magetsi aziyenda bwino.
Kubwezeretsa ndi Kugwiritsa Ntchito Kutentha Kotayika
Panthawi yozizira ya uvuni wa graphitization, kutentha kotayira kumabwezedwa kuti kutenthetsedwe kwa zinthu zopangira kapena kupanga madzi otentha, zomwe zimachepetsa kugwiritsa ntchito mphamvu yowonjezera. Mwachitsanzo, kampani ina imasunga ma cubic metres opitilira 500,000 a gasi wachilengedwe pachaka kudzera mu njira yobwezeretsa kutentha kotayira.
III. Kulimbitsa Zida Zopangira ndi Kuyang'anira Mphamvu
Kupititsa patsogolo Kugwiritsa Ntchito Mphamvu Mwachangu kwa Zipangizo
Kusankha ma extruder amphamvu kwambiri, ma screw extruder, ndi zida zina zopangira zinthu kumachepetsa kutayika kwa kukangana kwa makina; kugwiritsa ntchito ukadaulo wosinthasintha wa ma frequency drive kuti ulamulire liwiro la injini kuti ligwirizane ndi katundu wopangidwa ndikuchepetsa kugwiritsa ntchito mphamvu zopanda ntchito.
Kusamalira zida zofunika nthawi zonse, monga uvuni wophikira ndi graphitization, kumathandizira kuti mpweya usalowe komanso kuchepetsa kutaya kutentha. Mwachitsanzo, kukonza zigawo zotetezera ng'anjo kungachepetse kugwiritsa ntchito mphamvu ya ng'anjo imodzi ndi 8%-12%.
Kuwunika ndi Kukonza Mphamvu
Kugwiritsa ntchito Energy Management System (EMS) kumathandiza kuyang'anira magetsi, gasi, ndi kutentha nthawi yeniyeni m'njira zosiyanasiyana, kukonza mapulani opanga kudzera mu kusanthula deta. Mwachitsanzo, kusintha momwe uvuni wophikira umagwirira ntchito kutengera kufunikira kwa oda kumapewa zochitika "zokulirapo".
Kukhazikitsa njira zogulira magetsi m'chigwa chachikulu kumakonza njira zogwiritsira ntchito mphamvu zambiri (monga, graphitization) nthawi zina osati nthawi yogwira ntchito kwambiri kuti muchepetse ndalama zamagetsi.
IV. Kulimbikitsa Ukadaulo Wosunga Mphamvu ndi Mphamvu Yoyera
Kugwiritsa Ntchito Ukadaulo Wopanga Kutentha Kotsika
Kusintha njira zachikhalidwe zopangira mphamvu yamagetsi yokhala ndi mphamvu yamagetsi yokhala ndi kutentha kochepa kapena kusinthasintha kwa kutentha kumachepetsa kugwiritsa ntchito mphamvu yamagetsi yotentha. Mwachitsanzo, kampani ina inachepetsa kugwiritsa ntchito mphamvu pa tani imodzi ya ma elekitirodi omwe amapangidwa ndi 20% kudzera mu njira zopangira mphamvu yamagetsi yokhala ndi kutentha kochepa.
Kulowa M'malo mwa Mphamvu Yoyera
Kuyika pang'onopang'ono gasi wachilengedwe ndi mafuta achilengedwe m'malo mwa malasha mu njira zophikira ndi kuphika kumachepetsa kutulutsa mpweya wa carbon ndi ndalama zamagetsi. Mabizinesi ena apeza kugwiritsa ntchito gasi wachilengedwe woposa 60%, kuchepetsa kutulutsa kwa CO₂ pachaka ndi matani opitilira 10,000.
Kupanga Mphamvu Yotentha ndi Kugula Magetsi Obiriwira
Kugwiritsa ntchito kutentha kochokera ku ng'anjo za graphitization popanga magetsi kumakwaniritsa zosowa zamagetsi zochepa; kupeza magetsi obiriwira (monga mphepo kapena mphamvu ya dzuwa) kumachepetsa kudalira mafuta opangidwa ndi zinthu zakale ndipo kumalola kupanga mpweya wochepa.
V. Kukhazikitsa Kasamalidwe Kosunga Mphamvu Mokwanira
Kukonza Mapulani Opangira
Kuphatikiza njira zofanana (monga kuyika pakati ndi kuphika) kumachepetsa nthawi yoyambira zida ndikuchepetsa kugwiritsa ntchito mphamvu zomwe sizikugwira ntchito nthawi zonse. Mwachitsanzo, kampani ina inasunga magetsi opitilira 2 miliyoni kWh pachaka kudzera mu kukonza nthawi yopangira.
Maphunziro Othandiza Kusunga Mphamvu kwa Ogwira Ntchito
Kuchita maphunziro ogwiritsira ntchito mphamvu zosungira mphamvu nthawi zonse kumawonjezera chidziwitso cha antchito. Mwachitsanzo, kukhazikitsa njira zoyambira/kuzimitsa zida komanso kukonza njira zoyendetsera zinthu kungachepetse kugwiritsa ntchito mphamvu ndi 5%-8%.
Zolemba za Milandu
- Kampani Yaikulu ya Graphite Electrode: Mwa kukweza kukhala uvuni wa LWG graphitization, kugwiritsa ntchito njira ya EMS, ndikuyika malasha m'malo mwa gasi wachilengedwe, kampaniyo idachepetsa kugwiritsa ntchito mphamvu zonse ndi 35%, idachepetsa kutulutsa kwa carbon kuchokera kuzinthu zopanga ndi 40%, ndikusunga ndalama zoposa $7 miliyoni pachaka.
- Machitidwe Oyesera Makampani: Mabizinesi ena apanga "mpweya wochepa kwambiri" pogwiritsa ntchito njira zobwezeretsera kutentha ndi njira zogulira magetsi obiriwira, mogwirizana ndi zomwe zikuchitika padziko lonse lapansi pankhani yosagwirizana ndi mpweya wa carbon ndikuwonjezera mpikisano pamsika.
