Counterflow pot calciner

Abstract

Provided is a counterflow calcine furnace, which comprises a material tank (1), a fire channel (5) disposed at two sides of the material tank (1), a front wall, and a rear wall. A volatile component gathering channel (2) is disposed above the material tank, a front wall volatile component vertical channel (3) is disposed inside the front wall, a rear wall volatile component vertical channel (4) is disposed inside the rear wall, the front wall volatile component vertical channel communicates with the volatile component gathering channel (2) and a bottom layer fire channel, a volatile component pulling plate (6) is disposed at the entrance of the bottom layer fire channel, the rear wall volatile component vertical channel communicates with the volatile component gathering channel and the second lowest layer fire channel and the middle portion fire channel, a volatile component pulling plate (6) is disposed at the entrances of the second lowest layer fire channel and the middle portion fire channel, a preheating air channel is disposed below the bottom layer fire channel, a preheating air pulling plate (7) is disposed at the entrance of the preheating air channel, the preheating air channel communicates with the rear wall of the bottom layer fire channel, the first layer fire channel communicates with a flue (8), a cooling water sleeve (10) is disposed below the material tank. The calcine furnace is capable of increasing the maximum calcining temperature, so as to improve the quality of products.

Description

technical field [0001] The invention relates to a pot-type calciner, in particular to a counter-current pot-type calciner for producing aluminum anodes, cathodes, electrodes and carbon graphitized materials in the carbon industry. Background technique [0002] With the continuous increase of production capacity of modern carbon enterprises, especially large-scale electrolytic aluminum plants and electrode plants, while the production capacity of carbon products continues to increase, the requirements for the quality of calcined coke are becoming more and more stringent. Now the electrolytic cell current is gradually increasing, the anode current density is increasing, and the degree of automation is gradually increasing, so the quality requirements for carbon anodes are also gradually increasing. Calcination is the first process of anode products, and the quality of calcined coke largely determines the quality of anodes. At present, the commonly used calcination equipment ...
