Sintering umshini igalelo udini kanye Indwangu ukunwetshwa amalunga omzimba

Sintering mshini emoyeni kushaywa ngokusebenzisa batch ungqimba (Figure 3.6.) Ingabe esakhiwe nokusebenzisa kanje. Ngo ikhamera nge fan Pallet ungqimba icala ophoqelelwe emoyeni. Zonke legatsha lomtshikatshika umshini sintering ifakwe indawo ukuqoqwa kuhhonela amagesi kanye kudalwa izimo ezinhle sanitary umsebenzi esitolo. Isikhala emthunzini kunemibandela wahlukaniswa ngamaqembu amagatsha amabili: gas ocebile (olujulile esivuthayo zone), futhi abampofu (langemuva) igesi. Esikhathini ocebile igesi zone 9 elitholakala igalelo emakamelweni Indwangu ukunwetshwa amalunga omzimba lapho umoya ihlinzekwa ecindezelwa fan ahlukene 3-4 KPA, e igesi mafutha - 6 ohlabayo emakamelweni nge fan ehlukile. Amagesi kusukela nendawo yokuhlala ukusivumela eceleni abalandeli ababili isikhoselo ngaphansi cleaner labangaba ngu-20-KPA. amagesi Rich kusukela 5-7% sulphur dioxide siqondiswe ukukhiqizwa sulfuric acid. Kulezi ukushintsha 55-60% we-sulphur eziqukethwe kwenkokhelo. amagesi abampofu 2-2.5% sulphur dioxide noma ezase wafuthela ngowokuqala emakamelweni 9 (operation recirculation) noma ngemva ukupholisa ukuba 450-500 ° C kuya ku-80 ° C ithunyelwe uthuli iqoqo isikhwama izihlungi futhi lingashajwa emkhathini. Thina nishaye agglomachines node ezahlukene okhela ukukhokha. Esivunguzela sintering umshini unikezwe okuphakelayo hoppers ezintathu: ngoba i-ungqimba embhedeni kanye core kwenkokhiso incendiary. Ukuphakama ungqimba Umbhede 15-20 mm, 20-25 mm ungqimba incendiary futhi base ungqimba 200-250 mm. Umbhede ibhalwe kusuka afundwa agglomerate ubukhulu kuyizinhlayiyana ka 8-15 mm. ungqimba Incendiary kuyinto encane okuyinto ehlukaniswe ukubhonga ngaphambi kulayishwa kwenkokhiso engumucu Sinter. Incendiary uphondo nezicubu compensators nge gas noma uwoyela izitofu elise phakathi ungqimba Element kanye nengaphakathi kwenkokhiso incendiary. ungqimba elikhanyayo ezihambayo kanye iribhoni, ushiya ungqimba indleko main. Ngaphansi wasentabeni cleaner ekamelweni kuphela, lapho cleaner kuyinto 1-1.5 KPA. Specific umkhiqizo agglomachines nishaye udini kuyinto 13-18 t / (m2sut). Kubi nge-sulphur dioxide igesi Sinter ngaphandle usebenzisa njengoba afundwa recirculating izifunda okufanele abekeke emva ukususwa uthuli ukucutshungulwa ehlukile, isib, indlela citrate, njengoba ukusebenza kule ukufakwa sengisiza US izitshalo. Negesi (Figure 3.8.) Ingabe fed kukholamu ukumuncwa nge umlomo wombhobho futhi ushukumisela countercurrently nge isixazululo of citric acid. Nekusebenta ukumuncwa kwe-sulphur dioxide of citric acid 96-99%. Isixazululo ngemva ukumuncwa ziphathwe hydrogen sulfide ukuze sulphur zokucathula. Iincwadi ezingakatloleki kuhle ngemva ngokuhlukana we-sulphur akhishwa ku indawana ekhethekile lapho kaphalafini yengezwe flotation nesibabule. I-sulphur walulama Incibilikile futhi batheleka isisindo Ukuxoshwa 45 kg. isixazululo ezivuselela of citric acid kusukela cell flotation ebuyiselwa ikholomu ukumuncwa. Umthamo we gas 2.8-4.2 m3 / imiz igesi Sulphur - 816 kg / usuku.
