Refractories for Hazardous Waste incineration Rotary Kiln

Zowonongeka zomwe zimagwiritsidwa ntchito mumoto wozungulira wa zinyalala zowopsa zimawotchedwa ndi zinthu zovuta komanso zosakhazikika.Cholinga cha kuwerengetsa ndikuwotcha zinyalala zowopsa kukhala slag ndi kuchepetsa kutsika kwa kutentha kwa zotsalira kuchepera 5%. , njira yosankha yosankhira zinyalala mung'anjo yowotchera zinyalala ndi yosiyana kwambiri ndi ya ng'anjo yozungulira.

Pazinthu zokanira zomwe zimagwiritsidwa ntchito mu ng'anjo yozungulira pochiza zinyalala zowopsa, kapangidwe kake ka zinyalala zowopsa ndizovuta chifukwa cha mitundu yake yosiyanasiyana, kotero zimaganiziridwa kuti mankhwala a zinyalala zowopsa amawotchedwa pa kutentha kwa 700-1000 mu ng'anjo zozungulira, ndipo Kuchuluka kwa mpweya wotulutsidwa pambuyo powerengera zinyalala zowopsa kumakhala acidic pang'ono.

Mu refractory, refractory castable kwa mpweya acidic ali bata wabwino, AL2O3 SiO2 zinyalala rotary ng'anjo ndi zabwino dzimbiri kukana ndi castable refractory, posankha refractory zinthu, osati kusankha mankhwala refractory, Fe2O3 zili mmene ndingathere chifukwa Fe2O3 FeCL3 amachitira ndi mpweya wa klorini, gawo la mpweya, wosasunthika komanso wochuluka kwambiri wa njerwa yowumitsa, ng'anjo yozungulira simenti imagwiritsidwa ntchito kwambiri pakukana kwa dzimbiri kwa zinthu zoteteza chilengedwe Magnesia iron spinel njerwa, mu zinyalala zowopsa za ng'anjo yamoto kusankha zinthu zokanira sikoyenera, muzowopsa. zinyalala ng'anjo ng'anjo chakudya ndi potuluka castable, ayeneranso kusankhidwa otsika simenti castable, chifukwa simenti CaO ndi chlorine anachita, mapangidwe madzi gawo CaC1 kuchepetsa kukana kutentha ndi kutentha bata wa castable.

Posankha zida zodzitetezera, ng'anjo yowotchera zinyalala yowopsa iyenera kugwiritsa ntchito zida zokanira zokhala ndi mphamvu yolimba, kukhazikika kwamphamvu kwa kutentha komanso kukana dzimbiri. Kapangidwe ka ng'anjo yowotchera zinyalala zowopsa nthawi zambiri imatenga njira yowotchera pansi. Zinyalala zowopsa zamphepo zimalowa kuchokera mbali imodzi ndipo kutalika kwa ng'anjo kumakhala kocheperako (chiyerekezo cham'mimba mwake nthawi zambiri chimakhala 3-5m). Zomwe zimachitika mu uvuni ndizosavuta, ndiko kuti, kuyaka kwa okosijeni. Pazinthu zamakono zamakono, njerwa ya mullite sic ndi chinthu choyenera kwambiri, ndipo zinthu zowonongeka zimatha kusankhidwa mullite.
