Tank calciner U-shaped open circulation cooling system and cooling method

Abstract

The invention relates to the field of tank calciner cooling, specifically a U-shaped open circulation cooling system and cooling method for a tank calciner, and particularly relates to a tank furnace used in the carbon industry to produce anodes, cathodes, electrodes for aluminum and carbon graphitization materials. Cooling system and method for medium-forged coke. The system is equipped with a cooling water jacket, a U-shaped return pipe, a cup-shaped container, and a reservoir. The specific structure is as follows: the cooling water jacket and the reservoir are connected through a return channel, and a cup-shaped container is provided on the return channel. One end of the water channel is equipped with a U-shaped return pipe. One end of the U-shaped return pipe is connected to the water outlet of the cooling water jacket. The other end of the U-shaped return pipe leads into a cup-shaped container. The cup-shaped container is connected to the reservoir through the pipeline. The water reservoir is connected to the cooling water jacket through the water inlet pipe. The invention can solve the problems existing in the existing cooling system such as empty burning at the top of the water jacket, local overheating, easy welding, short service life, inability to monitor the return water system, and low cooling efficiency.

Description

Technical field

[0001] The invention relates to the field of tank calciner cooling, specifically a U-shaped open circulation cooling system and cooling method for a tank calciner, and particularly relates to a tank furnace used in the carbon industry to produce anodes, cathodes, electrodes for aluminum and carbon graphitization materials. Cooling system and method for medium-forged coke. Background technique

[0002] Calcination refers to the process of high-temperature heat treatment of raw materials under air-isolated conditions. The purpose is to eliminate moisture and volatile matter in the raw materials, fully shrink the volume of the carbon raw materials, and improve the thermal stability and physical and chemical properties of the materials. The tank calciner is used to calcine carbon raw materials, which has the characteristics of high heat utilization rate, high calcining temperature, uniform calcined coke quality, small burning loss, high strength, low resistivity,...
