An intelligent temperature control system and temperature control method for a calciner kiln

Abstract

The invention relates to the technical field of petroleum coke calcining in the carbon product industry, in particular to an intelligent temperature control system and method for a calcining furnace kiln. The intelligent temperature control system comprises a plurality of calcining furnace burden tanks; each calcining furnace burden tank is provided with a temperature adjusting and controlling device, and comprises an air door control device and a fire discharging port control device; each temperature adjusting and controlling device controls the actions of the corresponding air door control device and the corresponding fire discharging port control device so as to adjust the temperature of the corresponding calcining furnace burden tank; each temperature adjusting and controlling device performs remote adjusting and controlling setting through an intelligent adjusting and controlling terminal; and the calcining furnace burden tanks are arranged in a parallel connection manner. According to the intelligent temperature control method, the real-time temperature in the calcining furnace burden tanks is compared with a preset temperature interval periodically, the opening states of anair door and a fire discharging port are automatically controlled, it is achieved that the temperature of a calcining furnace is accurately controlled in time, it is avoided that high temperature damages the calcining furnace or low temperature affects the product quality, the service life of the calcining furnace is greatly prolonged, the percent pass of products is greatly increased, and the labor intensity of workers is relieved.

Description

technical field [0001] The invention relates to the technical field of petroleum coke calcination in the carbon industry, in particular to an intelligent temperature control system and a temperature control method for a calcination kiln. Background technique [0002] At present, forged petroleum coke is required in the fields of steelmaking, aluminum carbon products, graphite electrodes, carbon electrodes, etc. Petroleum coke calcining equipment mainly includes rotary kiln and tank-type calcination. It is widely used in domestic carbon factories to produce forged petroleum coke for prebaked anodes for aluminum due to the advantages of small burning loss, high calcination quality, and realization of calcination without additional fuel. Tank-type calciner kilns have been using manual temperature adjustment. This method of temperature control is very rough. Not only is the quality of the calcined carbon products difficult to control, but it is also easy to burn the kiln due to ...

AI Technical Summary

Problems solved by technology

Tank-type calciner kilns have been using manual temperature adjustment. This method of temperature control is very rough. Not only is the quality of the calcined carbon products difficult to control, but it is also easy to burn the kiln due to local high temperatures in a short period of time. With the development of technology, the number of kiln tanks is increasing, the volume is also increasing, and there are more and more temperature adjustment points. The traditional manual temperature adjustment method can no longer meet the normal production needs; in addition, Manual temperature adjustment also requires a lot of worker experience and sense of responsibility, but the energy of the workers is limited, and the kiln does not stop when the workers are on shift. It is inevitable that negligence will cause the temperature of the kiln to be too high or too low during the shift. Affect the service life of the kiln and the quality of the product
