A kind of tank calciner volatile matter channel

Abstract

The invention relates to a volatile matter channel for a pot type calcining furnace. The volatile matter channel for the pot type calcining furnace comprises a material pot, a material pot upper portion volatile matter concentrated channel, a front wall and a rear wall; a front wall volatile matter vertical channel is formed inside the front wall; a fire channel smoke concentrated channel is arranged on the lower portion of the front wall; the front wall volatile matter vertical channel is directly communicated with the fire channel smoke concentrated channel from the material pot upper portion volatile matter concentrated channel; a first layer fire channel volatile matter concentrated channel, a third layer fire channel volatile matter concentrated channel and a fifth layer fire channel volatile matter concentrated channel are communicated with the front wall volatile matter vertical channel; a rear wall volatile matter vertical channel is formed inside the rear wall; a second layer fire channel volatile matter concentrated channel, a fourth layer fire channel volatile matter concentrated channel and a sixth layer fire channel volatile matter concentrated channel are communicated with the rear wall volatile matter vertical channel. The volatile matter channel for the pot type calcining furnace has the advantages of enabling redundant volatile matters in high volatile matter raw materials to be directly discharged to the fire channel smoke concentrated channel through the front wall volatile matter vertical channel, enabling energy of the redundant volatile matters after burning to be utilized by following devices and not needing return matching technology.

Description

technical field [0001] The invention relates to a volatile matter passage structure, in particular to a pot type calciner volatile matter passage for producing prebaked anodes, cathodes, electrodes and carbon graphitized materials. Background technique [0002] With the westward movement of domestic electrolytic aluminum production capacity, tank-type calciners are more and more popular in the production of prebaked anodes. The calcined products are of good quality and have small burning losses. However, compared with rotary kilns, tank-type furnaces have an obvious disadvantage. : The environmental protection situation of the tank furnace is relatively poor. The main reason is that if the volatile matter in the raw material is relatively large, the excess volatile matter will be released and burned through the cleaning hole of the furnace surface.

[0002] With the westward movement of domestic electrolytic aluminum production capacity, tank-type calciners are more and more popular in the production of prebaked anodes. The calcined products are of good quality and have small burning losses. However, compared with rotary kilns, tank-type furnaces have an obvious disadvantage. : The environmental protection of the tank furnace is poor

The main reason is that if the volatile matter in the raw material is relatively large, the excess volatile matter will be released and burned through the cleaning hole of the furnace surface. The surface environment is harsh, which affects the operation and health of employees, and the release of volatile matter depends on manual experience. If more volatile matter is released, the furnace will lack energy, and the product quality is not up to standard. If the release is too small, the furnace will overheat and reduce the service life of the furnace.

If you want to avoid the dangerous operation of "fire" on the furnace head, you must use the back-mixing process, which will reduce the output by about 15%
