Cooling water jacket of pot type calcining furnace

Abstract

The invention relates to a cooling water jacket of a pot type calcining furnace. The cooling water jacket is structurally composed of an upper water jacket and a lower water jacket, the upper water jacket is of a structure with a narrower bottom and a wider top, the lower water jacket is of a structure with a wider top and a narrower bottom, a water outgoing pipe I and a water outgoing pipe II are arranged on the upper portion of the upper water jacket, a water incoming pipe I and a water incoming pipe II are arranged on the lower portion of the lower water jacket, the lower portion of the upper water jacket and the upper portion of the lower water jacket are communicated through a connecting pipe, and the connecting pipe is arranged outside the upper water jacket and the lower water jacket. The cooling water jacket of the pot type calcining furnace has the advantages that mounting space of a furnace bottom is saved, steam girder arrangement space of the furnace bottom is increased, and maintenance of the cooling water jacket is facilitated; heat exchange area is greatly increased through the structure with narrower top and bottom and a wider middle than conventional structures, and cooling effect is more excellent; by the arrangement, cooling water can flow smoothly, flowing dead areas of the cooling water can be reduced, and cooling effect can be greatly improved; and an exhausting device is mounted, so that vaporized steam in the cooling water jacket can be exhausted smoothly, material cooling effect is guaranteed, and the service life of the cooling water jacket is prolonged.

Description

technical field [0001] The invention relates to a cooling water jacket of a tank type calcination furnace, in particular to a cooling water jacket for calcined coke in a tank type furnace for producing aluminum anodes, cathodes, electrodes and graphitized carbon materials in the carbon industry. The calcined raw materials include petroleum coke, Pitch coke, anthracite, etc. Background technique [0002] The main purpose of calcination is to remove the water and volatile matter in the raw coke, so that the material shrinks, the structure becomes dense, the crystal lattice is formed, and the physical and chemical properties are changed. The maximum calcination temperature determines the final quality of calcined coke, including true density, resistivity, air reactivity, carbon dioxide reactivity, etc. Tank calciner is widely used due to its unique advantages in calcining carbon raw materials. [0003] After the raw coke is calcined at high temperature, the temperature is as...

Problems solved by technology

The high-temperature material is indirectly cooled by the cooling water during the process of passing through the cooling water jacket. If the heat transfer effect is not good or the cooling water flow is not smooth, the temperature of the material discharged to the belt is high, which greatly reduces the service life of subsequent equipment.
