Kufunika Kokulitsa Ukadaulo Wamakono Wamakono Wamakono

Laimu ndiye nkhani yayikulu komanso yothandiza popanga zitsulo, kupanga calcium carbide, kupanga kotsutsa, kupanga aluminiyamu. Makamaka munyengo yatsopano, ukadaulo watsopano, zopangidwa zatsopano zikupitilizabe kupanga zida za calcium zomwe zikugwiritsidwa ntchito kwambiri. Kuchita kwatsimikizira kuti ukadaulo wamakono wa laimu ndiwowona mtima komanso njira yachidule yopindulitsa mabizinesi azitsulo ndi zitsulo, mabizinesi a calcium carbide, mabizinesi a coking ndi zina zambiri. Pakadali pano, phindu la tani ya laimu laposa phindu la matani achitsulo, matani achitsulo, matani a calcium carbide, matani a coke. Mabizinesi omwe agwiritsa ntchito ukadaulo wamakono a laimu apindula kwambiri, ndipo apindula kwambiri ndi chikhalidwe chawo. Komabe, mabungwe ambiri amaletsedwa ndi kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendedwe kake. Chifukwa chake, ngati tikufuna kuwongolera bwino kuwonongeka kwa uvuni wa nthaka, tiyeneranso kudalira kukhazikitsa kwa uvuni wamakono wa laimu kuti tithetse vuto lakufuna.

Zomwe zimatchedwa ukadaulo watsopano wamakono ndi njira yasayansi yowerengera laimu ndi kuteteza zachilengedwe, ntchito yopulumutsa mphamvu, makina ndi zochita zokha. Chifukwa njirayi imagwiritsa ntchito ukadaulo wamakono wotentha, imatha kugwiritsa ntchito mphamvu zonse, makamaka mpweya womwe umawononga chilengedwe monga gwero lamagetsi ndikusandutsa zinyalala kukhala chuma. Izi sizimangoteteza chilengedwe, komanso zimatulutsa laimu wabwino komanso wotsika mtengo. Ubwino wake wachindunji komanso wosadziwika, maubwino azachuma komanso chikhalidwe ndiwofunika kwambiri. Izi ndizofunikira pakudziwitsa ukadaulo watsopano wa laimu.

2. Mitundu yaukadaulo waukadaulo wamakono

Pali mailo osakanikirana ndi mafuta, ndiye kuti, mafuta olimba, coke, ufa wa coke, malasha ndi uvuni wamagesi. Uvuni gasi zikuphatikizapo kuphulika ng'anjo mpweya, coke uvuni mpweya, calcium carbide mchira mpweya, gasi ng'anjo, gasi ndi zina zotero. Malinga ndi mawonekedwe a uvuni, pali uvuni woyatsira, uvuni woyenda, uvuni wamanja, uvuni wa Vimast (West Germany), uvuni wa Melz (Switzerland), uvuni wa Fucas (Italy) ndi zina zambiri. Pa nthawi yomweyo, pali zabwino kuthamanga ntchito uvuni ndi zoipa anzawo ntchito uvuni. Utsi wamakono wosakanikirana ndi ma cubic metres 800 patsiku wotulutsa pansi pa 500 ndi uvuni wamakono wamakono wokhala ndi ma cubic metres 250, makamaka kupulumutsa mphamvu ndi kuteteza zachilengedwe uvuni woyaka ndi kuphulika kwa gasi la ng'anjo ndi kuyaka kwa gasi wamafuta a coke, apangidwa ndikupangidwa. Kupanga ndi kupanga kwa "launi yamoto yayitali yoyaka moto" kwathetsa vuto loyaka moto la calorific lalitali komanso lawi lalifupi la gasi wa uvuni wa coke, womwe ungagwiritse ntchito bwino mpweya wotsala wa coke. Kuchokera ku gasi woyambirira wa coke "kuyatsa", kuwononga chilengedwe kukhala mphamvu yamphamvu kuti mabizinesi apange phindu. Kwa mabizinesi ang'onoang'ono komanso apakatikati achitsulo komanso achitsulo, mabizinesi akunyumba, mabizinesi a calcium carbide, ndi makampani osokonekera ndiopulumutsa mphamvu, kuteteza zachilengedwe, kuchita bwino komanso njira zothandiza.

MFUNDO ZOTHANDIZA NDI NTCHITO YA ZIPANGIZO

Gawo lalikulu la miyala yamwala ndi calcium carbonate, pomwe gawo lalikulu la mandimu ndi calcium oxide. Mfundo yayikulu yotentha laimu ndikuwononga calcium carbonate mu miyala yamchere kukhala msanga wa calcium oxide ndi carbon dioxide mothandizidwa ndi kutentha kwambiri. Zomwe zimayendera ndizo

CaCO2CaO CO2–42.5KcaI

Njira yake ndikuti miyala yamiyala ndi mafuta amatenthetsedwa m'makina a mandimu (ngati mapaipi amafuta a gasi ndi zotentha zimadyetsedwa) ndikuzikongoletsa pamadigiri 850, zimayikidwa pamadigiri 1200, kenako zimakhazikika ndikutsitsidwa pamoto. Njira zake zonse zowerengera ndizofanana ndi kuchitidwa mu chidebe chosindikizidwa. Maonekedwe osiyanasiyana a uvuni ali ndi njira zothetsera kutentha, kuwerengetsa, kuzirala ndi kutsitsa phulusa. Komabe, mfundo zina zimafanana: kutentha kwa calcination ndi madigiri 850-1200, kutentha kwa madigiri ndi 100- -850 madigiri. Kutentha kwa phulusa kuli pansipa madigiri 100. Mtengo wa zopangira ndizokwera, mtundu wa laimu ndi wabwino; mafuta amafunika kwambiri, kuchuluka kwake ndikochepa; kukula kwa tinthu ta miyala yamiyala ndikofanana ndi nthawi yowerengera; digiri yantchito yofulumira ndiyofanana mofanana ndi nthawi yowerengera komanso kutentha kwa kuwerengera.
