Intelligent temperature-adjusting method of petroleum coke calcining furnace

Abstract

The invention provides an intelligent temperature-adjusting method of a petroleum coke calcining furnace. The intelligent temperature-adjusting method comprises the steps that the opening and closingdegree of a wedge disc of the petroleum coke calcining furnace is related to a temperature measurement result of a temperature measurement device of the petroleum coke calcining furnace, a curvilinearrelationship of the furnace temperature and the opening and closing degree of the wedge disc is set in a control system of the petroleum coke calcining furnace, the control system controls a wedge disc adjusting rod to push and pull the wedge disc to adjust furnace flames by the set corresponding opening and closing degree of the wedge disc after obtains the furnace temperature fed back by temperature measurement device of the petroleum coke calcining furnace, and the opening and closing degree of the wedge disc is intelligently adjusted with the changing of the furnace temperature. Accordingto the intelligent temperature-adjusting method of the petroleum coke calcining furnace, the size of a volatile wedge disc or an air wedge disc can be intelligently adjusted according to the real-time furnace temperature.

Description

technical field [0001] The invention relates to the technical field of petroleum coke calcination furnaces, in particular to an intelligent temperature regulation method for petroleum coke calcination furnaces. Background technique [0002] Petroleum coke is a black or dark gray hard solid petroleum product with a metallic luster and a porous appearance. It is a carbon body composed of tiny graphite crystals in the form of granular, columnar or needle-shaped. Petroleum coke components are hydrocarbons, containing 90-97% carbon, 1.5-8% hydrogen, and nitrogen, chlorine, sulfur and heavy metal compounds. Petroleum coke is a by-product of the cracking of raw oil in delayed coking unit at high temperature to produce light oil. The yield of petroleum coke is about 25-30% of the raw oil. Its low calorific value is about 1.5-2 times that of coal, the ash content is not more than 0.5%, the volatile matter is about 11%, and the quality is close to that of anthracite. In order to ma...

Problems solved by technology

The structure of the existing gate adjustment rod in the furnace is very simple, usually a structure with a right-angled hook at the end of a long rod, which has the following disadvantages: 1. When the gate is pushed and pulled, the open operation hole makes the furnace The high temperature directly radiates the face of the operator, which is not conducive to the labor protection of workers; 2. The opening size of the through hole is based on experience and feeling, which is random, so the adjustment of volatile matter or hot air is not accurate, and the operator needs experience. Only richness can be grasped well, which is seriously limited by the experience level of the operator; 3. The operator needs to open the observation window of the fire channel regularly to observe the temperature in the furnace, and then open the volatile gate or the air gate adjustment port to adjust the position of the gate through the adjustment rod ,low efficiency
