Countercurrent-tank-type calcining furnace

Abstract

The invention relates to a countercurrent-tank-type calcining furnace comprising material tanks, fire paths provided on two sides of the material tanks, a front wall, and a back wall. A volatile content centralization channel is arranged above the material tanks. A front wall volatile content vertical channel is arranged in the front wall. A back wall volatile content vertical channel is arranged in the back wall. The front wall volatile content vertical channel communicates the volatile content centralization channel and bottom-layer fire paths. Volatile content drawing boards are arranged at the inlet ports of the bottom-layer fire paths. The back wall volatile content vertical channel communicates the volatile content centralization channel and last-but-two-layer fire paths and middle-part fire paths. Volatile content drawing boards are arranged at inlet ports of the last-but-two-layer fire paths and the middle-part fire paths. A preheated air channel is arranged below the bottom-layer fire paths. A preheated air drawing board is arranged at the inlet port of the preheated air channel. The preheated air channel and the bottom-layer fire paths are communicated at the front wall. First-layer fire paths are communicated with a flue. A cooling water jacket is arranged below the material tanks. With the furnace provided by the invention, maximal calcining temperature can be increased, such that product quality can be improved.

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 ...
