Large-sized anode roasting furnace for producing charcoal for aluminum

Abstract

The invention relates to a large-sized anode roasting furnace for producing charcoal for aluminum. The large-sized anode roasting furnace comprises a single open type annular roasting furnace formed by connecting 72 furnace chambers end to end, wherein each 18 furnace chambers form a flame system; each of the 72 furnace chambers is provided with 15 flame path walls and 14 material boxes; and S-shaped bricks are symmetrically arranged on two sides of the flame path walls. The large-sized anode roasting furnace is simple in structure, and the unit anode roasting cost and the construction input can be substantially lowered.

Description

technical field [0001] The invention relates to an anode roasting furnace, in particular to a large anode roasting furnace for aluminum carbon production. Background technique [0002] In the carbon industry at home and abroad, carbon products are generally roasted in two furnace types: open ring roaster and covered ring roaster. On the one hand, the traditional open-type ring roasting furnace has brought enormous pressure to many carbon production enterprises due to its high cost, low production capacity, and large investment in equipment and personnel; on the other hand, the volatile content of pitch during the roasting process is stage into the roasting flue gas, because the temperature of the fire path in the preheating furnace chamber is low, and the combustion space in the fire path is small, so a large amount of volatile matter will not be fully burned in the fire path, and will be pumped to the furnace surface equipment and flue gas purification equipment with the fl...

Problems solved by technology

On the one hand, the traditional open-type ring roaster has brought great pressure to many carbon production enterprises due to its high cost, low production capacity, and large investment in equipment and personnel; on the other hand, the volatile content of the pitch during the roasting process is stage into the roasting flue gas, because the temperature of the fire path in the preheating furnace chamber is low, and the combustion space in the fire path is small, so a large amount of volatile matter will not be fully burned in the fire path, and will be pumped to the furnace surface equipment and flue gas purification equipment with the flue gas , resulting in equipment damage and excessive discharge

[0003] Therefore, in order to completely solve the disadvantages of high cost, low production capacity, large investment in equipment and personnel, and the volatilization of pitch during the roasting process, it is necessary to improve the roasting process technology and roasting furnace structure design.
