Automatic temperature control system for tank furnace

Abstract

The invention relates to a pot calciner, in particular to a pot calciner flue temperature automatic control system. The pot calciner flue temperature automatic control system comprises bottom layer local control systems and an upper layer central control system. Each pot calciner in a calcinating workshop is provided with one local control system. The local control systems are connected to the upper layer central control system through a network communication system, so that unified management and control over the bottom layer systems are achieved. The pot calciner flue temperature automatic control system has the advantages and effects that temperature distribution of all flues of each pot calciner in the calcinating workshop is precisely controlled, and further, and unified management for all detection and control data of the whole workshop can be achieved; and the system can be used for replacing manual temperature regulation, decreasing the manpower quota and improving the pot calciner production stability and product quality uniformity, furthermore, fluctuations of flue temperatures within target ranges can be precisely controlled, the overheating phenomenon is prevented, and the service lives of the pot calciners are greatly prolonged.

Description

Technical field [0001] The invention relates to a tank furnace, in particular to a tank furnace fire channel temperature automatic control system, which is applied to a tank furnace for the production of aluminum anodes, cathodes, electrodes and carbon graphitized materials in the carbon industry. Background technique [0002] In recent years, due to the continuous decline in electrolytic aluminum prices, the high production costs of enterprises, and the relatively high price of raw materials in the market, the pot calciner has more prominent advantages in the field of petroleum coke calcining and gradually occupy the market. However, the low level of automation and low labor efficiency of retort furnaces are recognized facts in the industry. The retort furnace product depends on the temperature distribution of the material box, and the temperature of the material box depends on the flame shape and temperature distribution in the fire channel. However, at present, the temperatur...

AI Technical Summary

Problems solved by technology

However, at present, the temperature control in the production of tank furnaces depends entirely on manual intervention and production experience. Not only is the labor intensity high, and many temperature adjustment positions are required, but also the temperature adjustment is not timely, and the temperature difference in the fire path is large, which seriously affects the product. quality stability

[0003] More importantly, artificial temperature adjustment often makes mistakes, which makes the temperature of the flue path overheated, which has a great negative impact on the life of the refractory material in the flue path of the tank furnace.
