Sintering makina nkhonya akamaumba ndi nsalu mfundo kuwonjezeka

Sintering makina ndi mpweya zokula kudzera mtanda wosanjikiza (Chithunzi 3.6.) Kodi inamangidwa ndi ntchito motere. Mu kamera ndi kukolezera mphasa wosanjikiza mlandu kukakamizidwa mpweya. onse nthambi ntchito ya makina sintering ali okonzeka ndi pogona kwa mndandanda wa mpweya uvuni ndi chilengedwe cha zinthu zabwino ukhondo ntchito mu shopu. Danga pansi pogona ndi salembedwa analigaŵa m'zigawo ziwiri: mpweya wolemera (kwambiri woyaka zone), ndi osauka (paseri) mpweya. Mu wolemera mpweya zone 9 Chilwa mfundo zipinda nkhonya nsalu Kukula amene mpweya umaperekedwa wapanikizidwa osiyana zimakupiza 3-4 kPa, mu mpweya Taphunzira - 6 kuwomba zipinda ndi fani osiyana. Mpweya m'nyumba ya mawere payokha mafani awiri kupereka pogona pansi zingalowe pafupifupi 20 kPa. mipweya wolemera kwa 5-7% woipa sulfure walangizidwa yopanga asidi sulfuric. Mu masiwichi izi 55-60% sulfure amene ali mlandu. mipweya osauka 2-2.5% woipa sulfure kapena zobwezerezedwanso nauzira woyamba zipinda 9 (ntchito ndi recirculation) kapena pambuyo yozizira kuti 450-500 ° C 80 ° C ndi kutumizidwa ku fumbi zosonkhanitsira Zosefera thumba kudzapereka m'mlengalenga. Ife kuwomba agglomachines mfundo zosiyana azinyadira mlandu. Ikuwomba sintering makina kupatsidwa hoppers chakudya atatu; pakuti bedi wosanjikiza ndi pachimake mlandu incendiary. Kutalika kwa bedi wosanjikiza ndi 15-20 mm, 20-25 mamilimita incendiary wosanjikiza ndi wosanjikiza m'munsi mwa 200-250 mm. Kama zakonzedwa ku kufalitsidwa agglomerate tinthu kukula kwa 8-15 mm. Incendiary wosanjikiza ndi kagawo kakang'ono amene anapambulwa pa mkokomo pamaso tsegula mlandu kwa sinter timafupa. Incendiary nyanga ndi minofu compensators ndi mpweya kapena mafuta woyatsa lili pakati pa wodyetsa wosanjikiza ndi pachimake mlandu incendiary. Linawala wosanjikiza kuyendera ndi riboni, n'kusiya wosanjikiza mlandu waukulu. Pansi m'phiri kokha zingalowe chipinda, mmene zingalowe ndi 1-1.5 kPa. Specific zokolola agglomachines kuwomba akamaumba ndi 13-18 T / (m2sut). Osauka ndi sulfure woipa sinter mpweya kupatula ntchito ngati kufalitsidwa madera recirculating adzatengedwe nkhati pambuyo kuchotsa fumbi osiyana processing, mwachitsanzo, citrate njira, monga akuyendera unsembe wa kutsogolera zomera US. Mpweya (Chithunzi 3.8.) Kodi kudyetsedwa kwa mayamwidwe mzati ndi nozzle ndi amasuntha countercurrently ndi njira ya citric acid. Mwachangu wa mayamwidwe woipa sulfure wa citric acid ndi 96-99%. Yankho pambuyo mayamwidwe ndi mankhwala sulfide wa hydrogen ndi sulfure elemental. Zamkati pambuyo kulekana kwa sulfure ndi amawapopa mu chipinda wapadera komwe palafini ndi anawonjezera kuti asamire sulfure. Sulufule anachira isungunuke nawatsanulira mu kuponyera kulemera kwa makilogalamu 45. Kusinthidwa njira ya citric acid mukachipinda flotation amagwanso ndime mayamwidwe. Kukhoza mpweya ndi 2.8-4.2 M3 / Mph mpweya Sulfa - 816 makilogalamu / tsiku.
