Abstract

The invention relates to the cooling field of pot calciners, provides a U-shaped open-type circulated cooling system for pot calciners, and a cooling method, and particularly relates to a cooling system and method for calcined coke of anodes, cathodes, electrodes and carbon graphite materials for aluminum for production in the carbon industry in pot calciners. The U-shaped open-type circulated cooling system is provided with a cooling water jacket, a U-shaped backwater pipe, a cup-shaped container and a water storage tank, wherein the cooling water jacket is connected with the water storage tank through a backwater channel, the cup-shaped container is arranged on the backwater channel, the U-shaped backwater pipe is arranged at one end of the backwater channel, one end of the U-shaped backwater pipe is connected with the water outlet of the cooling water jacket, the other end of the U-shaped backwater pipe is communicated with the inside of the cup-shaped container, the cup-shaped container is communicated with the water tank through a pipeline, and the water tank is connected to the cooling water jacket through a water inlet pipe. The U-shaped open-type circulated cooling system disclosed by the invention solves the problems that in the cooling system in the prior art, the top of a water jacket is burnt without water, local parts are too hot, welded positions have high probability of cracking, the service life is short, the backwater system cannot be monitored, and the cooling efficiency is low.

Description

technical field [0001] The present invention relates to the field of tank-type calciner cooling, in particular to a tank-type calciner U-shaped open circulation cooling system and a cooling method, in particular to a tank-type furnace for producing aluminum anodes, cathodes, electrodes and carbon graphitization materials in the carbon industry A cooling system and method for intermediate calcined coke. Background technique [0002] Calcination refers to the process of high-temperature heat treatment of raw materials under the condition of isolation from air. The purpose is to remove moisture and volatile matter in raw materials, make the volume of carbon raw materials fully shrink, and improve the thermal stability and physical and chemical properties of materials. The carbon raw material is calcined in a pot calciner, which has high heat utilization rate, high calcining temperature, uniform calcined coke quality, small burning loss, high strength, low resistivity, stable ca...
