Sintering Umatshini igalelo yokubumba kunye nelaphu amalungu ukwanda

Sintering machine ngomoya eyivuthele nge umaleko ibhetshi (Figure 3.6.) Ngaba kwaye zisebenze ngolu hlobo. Xa ikhamera kunye fan isigxina pallet umaleko ngenkani emoyeni. Yonke isebe yabasebenzi kumatshini sintering kufakwa ngesigqubuthelo ukulungiselela ukuqokelelwa iigesi weziko kunye nokudalwa iimeko ezilungileyo yococeko umsebenzi evenkileni. Isithuba phantsi emthunzini phantsi kwemiqathango ethile yahlulwe imimandla emibini: igesi osisityebi (zone kakhulu ukutshisa), kunye namahlwempu (ngasemva) igesi. Kwamalunga amagumbi ngesibetho ngelaphu ukwanda zone igesi osisityebi 9 ime apho umoya nakwesiphi phantsi koxinzelelo oluvela fan eyahlukileyo 3-4 kPa, xa igesi ndayame - 6 amagumbi kuhanjwa fan eyahlukileyo. Yeegesi evela yokuhlala owawanyayo ngokwahlukeneyo abalandeli ezimbini ngokubonelela yokuhlala phantsi ongenawo malunga 20 kPa. igesi Rich ukusuka 5-7% sulphur dioxide sibhekiswe ukuveliswa kwe-sulphuric acid. Kwezi nokucima 55-60% ye-sulphur eziqulethwe isigxina. igesi Poor ukusuka 2-2.5% sulphur dioxide okanye esirisayikilishiweyo wavuthela zokuqala emagumbini 9 (intsebenziswano kunye recirculation) okanye emva okupholisa ukuya 450-500 ° C 80 ° C ithunyelwa yingqokelela eluthulini ibhegi okucoca lilahle yaya kwi-atmosfera. Thina bevuthela agglomachines node ezahlukeneyo phemba isigxina. Umatshini sintering makazichaze banikwe hoppers ezintathu ukutya; ngokuba umaleko bed and undoqo kwentlawulo sigade. Ukuphakama umaleko umandlalo 15-20 mm, 20-25 mm umaleko sigade noseko nocamba 200-250 mm. Umandlalo ilungisiwe ukususela esasaza ubukhulu bamagaqa agglomerate ka 8-15 mm. maleko sigade maqhezu encinane abazahlulayo kwi ukubharhula phambi yokulayisha sentlawulo mngxilo sinter. Sigade uphondo kunye inyama compensators ngegesi okanye ioli izitofu ephakathi umaleko feeder kunye undoqo kwentlawulo sigade. umaleko lighted ihamba kunye iribhoni, eshiya umaleko intlawulo engundoqo. Phantsi ntaba gumbi ezincamathelayo kuphela, apho ongenawo yi 1-1.5 kPa. agglomachines kwemveliso ethile ixilongo sukube yi 13-18 t / (m2sut). Abaziintsizana sulphur dioxide gas sinter ngaphandle ngokusebenzisa njengoko ajikeleza kwiisekethe ojikelezayo ukuze phantsi emva kususwa nothuli processing ezahlukeneyo, umz, indlela citrate, njengoko kuphunyezwa lofakelo phambili izityalo US. NeGesi (Figure 3.8.) Ngaba anikwe kumhlathi ukufakwa kunye umlomo ngokubhekiswa countercurrently kunye nesisombululo citric acid. Ukusebenza ukufakwa kwe-sulphur dioxide ye citric acid yi 96-99%. Isisombululo emva ukufunxeka iphathwa kunye emanzini ukuya nesalfure iziqalelo. Ido- emva ukungcola sulphur Impontshelwa ibe kwigumbi ekhethekileyo apho separafini yongezwe ayinto nesalfure. I-sulphur wachacha inyibilikiswa kwaye agalelwa ubunzima ekubunjweni 45 kg. isisombululo ahlume of citric acid kwiseli ayinto ibuyiswa kwekholam ukufunxeka. Umthamo igesi yi 2.8-4.2 m3 / min gas Isalfure - 816 kg / ngosuku.
