Technical Field

The invention relates to the technical field of petroleum coke calcination monitoring, in particular to a combustion monitoring system of a petroleum coke calciner.

Background

Petroleum coke is a black or dark gray hard solid petroleum product with metallic luster and porosity, and is a carbon substance formed by granular, columnar or needle-shaped crystals of tiny graphite. The petroleum coke component is hydrocarbon containing carbon 90-97 wt% and hydrogen 1.5-8 wt%, and also contains nitrogen, chlorine, sulfur and heavy metal compounds. Petroleum coke is a byproduct produced when raw oil of a delayed coking device is cracked at high temperature to produce light oil. The petroleum coke yield is about 25-30% of the raw oil. Its low-level heat productivity is about 1.5-2 times of coal, ash content is not greater than 0.5%, volatile component is about 11%, and its quality is close to that of anthracite. In the case of a graphite electrode for steel making or an anode paste (melting electrode) for aluminum or magnesium making, green coke must be calcined to meet the requirements for petroleum coke (green coke). The calcining temperature is generally about 1300 ℃, so that petroleum coke volatile components are removed as much as possible. Therefore, the hydrogen content of petroleum coke remanufacturing products can be reduced, the graphitization degree of the petroleum coke is improved, the high-temperature strength and the heat resistance of the graphite electrode are improved, and the conductivity of the graphite electrode is improved. The calcined coke is mainly used for producing graphite electrodes, carbon paste products, diamond dust, food-grade phosphorus industry, metallurgical industry, calcium carbide and the like, wherein the graphite electrodes are most widely applied.

The calcining of petroleum coke by a pot calciner is a processing technology which is commonly used at home and abroad. The indirect heating of the carbon material is realized in a fixed charging bucket, so that the carbon material is heated to complete the calcination process. The pot calciner is one of the furnace types widely used in the carbon industry. During calcination, the raw materials are added into the tank through the top feeding device, and are gradually heated by flame paths positioned at two sides of the charging tank in the process of moving from top to bottom. The heat generated by the combustion of the fuel in the flue is indirectly transferred to the feedstock through the walls of the flue. When the temperature of the raw materials reaches 350-600 ℃, a large amount of volatile components in the raw materials are released. The volatile components are collected through the volatile component channel and sent into a flame path for combustion. The combustion of volatiles is yet another source of heat for the can calciner. After a series of physicochemical changes of the raw materials are finished at a high temperature of more than 1200-1300 ℃, the raw materials enter a water jacket from the bottom of a charging bucket for cooling, and are finally discharged out of the furnace by a discharging device. The waste flue gas after heat exchange is sent to a waste heat boiler, and the waste heat is used for producing steam, or the waste flue gas is sent to a heat exchange chamber for preheating air for fuel supply and volatile matter combustion.

A large wall of the furnace body is provided with a plurality of flame path observation holes and temperature and pressure measuring holes, so that the furnace is convenient to operate and monitor, and the large wall is built by clay refractory bricks, insulating bricks and red bricks. At present, most petroleum coke production enterprises monitor the condition in the flame path through flame path observation holes, because the petroleum coke calcining furnace is composed of a plurality of small production unit 'cans', the temperature, negative pressure, volatilization and the like in each production unit need to be monitored in production, workers observe the condition in the flame path one by one, firstly, the labor intensity of the workers is high, the workers need to go back and forth along the calcining furnace for a plurality of times every day, and secondly, the actual condition of the flame cannot be preserved through the visual observation of the workers.
