Pot-type carbon calciner

Abstract

The invention discloses a pot-type carbon calciner and belongs to calciners for carbon production. One combustion chamber is formed by each four calcination pots and furnace walls with heating fire channels, the furnace walls with the heating fire channels are located on two sides of a pot body, expansion joints and smoke converging flues are arranged among the combustion chambers, each of the furnace walls with the heating fire channels has 8 to 10 layers of fire channels, the fire channels are communicated with a preheated air channel, the calcination pot body is connected with a material discharge pot, and an interlayer cooling water jacket is disposed on the periphery of the material discharge pot. The pot-type carbon calciner is characterized in that the entire calciner is formed by 18 combustion chambers which are linearly arranged and 72 calcination pots, a calciner protection large cutter frame is arranged outside the front wall of the calciner, a calciner protection frame is arranged outside the rear wall of the calciner, the bottoms of the combustion chambers are supported by supporting columns at the bottom of the calciner, a feed opening is disposed at the top of the calcination pot body, the material discharge pot is connected with the bottom of the calcination pot body, the interlayer cooling water jacket is disposed on the periphery of the material discharge pot, a material discharge device is installed at the lower end of the material discharge pot, and a small storage bin is mounted between the material discharge device and a discharge valve, so that volatile matter two-way utilization is achieved, the full-automatic closed type continuous discharging is achieved, and the pot-type carbon calciner has good economic and environmental benefits.

Description

technical field [0001] The invention belongs to a calcining kiln, in particular to a pot-type calcining furnace for carbon production. Background technique [0002] Tank calciner is a commonly used calcination equipment for carbon production. The material is isolated from the air in the tank for indirect heating and calcination to remove the volatile components in the carbon material. This calciner can make full use of the combustion of a large amount of volatiles released from the carbon material during calcination. Heat reduces energy consumption, but the existing tank-type calciner has shortcomings such as a small number of groups and insufficient air supply, resulting in insufficient use of waste heat, low calcining efficiency and quality. Contents of the invention [0003] In order to overcome the disadvantages of insufficient utilization of waste heat and low thermal efficiency of existing calcination furnaces, the present invention provides a pot-type carbon calcina...
