Sintering inji duka gyare-gyaren da kuma masana'anta fadada gidajen abinci

Sintering inji tare da iska a cikin ƙaho ta cikin tsari Layer (Figure 3.6.) An gina da kuma aiki kamar haka. A kamara da pallet Layer cajin fan tilasta iska. Duk da aiki reshe na sintering inji sanye take da wani tsari na tarin kiln gas da kuma halittar kyau yanayin tsafta na aiki a shagon. A sarari a karkashin tsari yanaye kasu kashi biyu zones: wani arziki gas (m kona zone), da kuma talakawa (a cikin raya) gas. A arziki gas zone 9 ayi duka bẽnãye masana'anta fadada gidajen abinci a wadda iska ake kawota a karkashin matsin lamba daga raba fan 3-4 kPa, a ramammu gas - 6 hurawa bẽnãye tare da raba fan. Gas daga tsara sucked dabam biyu magoya samar da tsari karkashin injin na game da 20 kPa. Rich gas daga 5-7% sulfur dioxide ne zuwa ga samar da sulfuric acid. A cikin wadannan sauya 55-60% na sulfur dauke a cikin cajin. Poor gas daga 2-2.5% sulfur dioxide ko sake yin fa'ida don busa a cikin na farko da bẽnãye 9 (aiki tare da recirculation) ko bayan sanyaya to 450-500 ° C zuwa 80 ° C da aka aiko zuwa ƙura tarin jakar tace cajuwa cikin yanayi. Mun busa agglomachines daban-daban kumburi ƙone da cajin. Hurawa sintering inji bayar da uku feed hoppers: ga gado Layer kuma da zuciyar incendiary cajin. A tsawo na gado Layer ne 15-20 mm, 20-25 mm incendiary Layer da tushe Layer na 200-250 mm. A gado da aka shirya daga zagawa da agglomerate barbashi size of 8-15 mm. Incendiary Layer ne a kananan sulusi da murabba'i wanda aka raba a ruri kafin loading cajin zuwa sinter tufka. Incendiary Kakakin kuma nama compensators da gas ko mai burners dake tsakanin Feeder Layer kuma da zuciyar incendiary cajin. Haske Layer motsi tare da kintinkiri, da barin wani Layer na babban cajin. A karkashin dutse ne kawai injin jam'iyya, a cikinsa injin ne 1-1.5 kPa. Specific yawan aiki agglomachines busa gyaren ne 13-18 t / (m2sut). Poor da sulfur dioxide gas sinter fãce yin amfani da matsayin da ake zagawa da a recirculating haihuwarka iya hõre bayan kau daga turɓãya raba aiki, msl, citrate hanya, kamar yadda aiwatar a cikin shigarwa na wani gubar Amurka shuke-shuke. Gas (Figure 3.8.) An ciyar da sha shafi tare da wani bututun ƙarfe da kuma motsa countercurrently tare da wani bayani da citric acid. Yadda ya dace da sha na sulfur dioxide da citric acid ne 96-99%. The bayani bayan da sha da aka bi da tare da hydrogen sulfide zuwa elemental sulfur. Ɓangaren litattafan almara bayan rabuwa da sulfur ne pumped cikin wani musamman jam'iyya inda kananzir da aka kara wa sulfur flotation. A gano sulfur da aka narke da kuma zuba a cikin wani simintin nauyi na 45 kg. Sake halitta bayani daga citric acid daga flotation cell da aka koma zuwa ga sha shafi. Da damar da gas ne 2.8-4.2 M3 / min gas Sulfur - 816 kg / rana.
