The utility model belongs to the technical field of annular furnace
smelting, and relates to a
system for preparing a novel furnace material by adopting an ultra-thick material layer, which comprises an annular
heating furnace and a
flue gas circulation subsystem, and the annular
heating furnace is sequentially divided into a
forced air drying section, an air draft preheating section, a reaction section, a first-stage cooling section, a second-stage cooling section and a discharging section according to the rotating direction; the
flue gas circulation subsystem comprises a
drying section fan cover, a preheating section fan cover, a reaction section fan cover, a cooling section fan cover, a
drying section
flue gas dust collection bin and a preheating section
flue gas dust collection bin installed below the air draft preheating section. The reaction section
flue gas dust collecting bin is mounted below the reaction section; the cooling section
flue gas dust collecting bin is mounted below the primary cooling section and the secondary cooling section; a
cooling medium conveying pipeline is connected to the bottom of the cooling section flue gas dust collecting bin, the cooling section fan cover is connected with the drying section flue gas dust collecting bin, the reaction section flue gas dust collecting bin is connected with the preheating section fan cover and the reaction section fan cover, and the drying section fan cover and the preheating section flue gas dust collecting bin are connected with a
chimney.
