Description
Technical Field
The utility model relates to a sintering machine gas jetting device, concretely relates to gas jetting device based on video identification belongs to sintering technical field.
Background
The sintering process is a key link in the iron-smelting process, and the principle is that various powdery iron-containing raw materials are mixed with proper amount of fuel and flux, proper amount of water is added, after mixing and pelletizing, the materials are subjected to a series of physical and chemical changes on sintering equipment, and are sintered into blocks, so that the blocks are sent to a blast furnace for the next working procedure.
In order to reduce the coke ratio and smelting cost of blast furnace ironmaking, the blast furnace often requires high strength and high reducibility for sintered ore. In the sintering process, the sintered ore is generally required to have higher strength, high yield, lower return fines rate and lower fuel consumption. The high-strength and high-reducibility sintered ore consumes less coke in the blast furnace smelting process, thereby reducing the emission of carbon dioxide. In the long run, the requirement of carbon dioxide emission reduction becomes one of the bottlenecks that restrict the development of the steel industry. According to the relevant data, the carbon dioxide emission of sintering and blast furnace processes accounts for about 60% of the total industrial emission. Therefore, reducing the consumption rate of the sintering solid fuel and reducing the fuel ratio of the blast furnace charge are urgent needs of the iron-making technology from the viewpoint of cost reduction of enterprises and environmental protection.
Therein, theUnder large environment, the 'sintering charge level gas fuel injection technology' developed by the Japan JFE company comes into play, and the principle is that gas fuel diluted to be below the lower limit of combustible concentration is injected above the sintering charge level at a distance behind an ignition furnace, so that the gas fuel is combusted in a sintering charge layer to supply heat, and the solid carbon consumption and CO in the production of sintering ore are reduced2And (4) discharging the amount. Meanwhile, the combustion of the gas fuel widens the width of a high-temperature belt of a sinter bed during production, so that the temperature time of the sinter at 1200-1400 ℃ is prolonged, and the strength and the porosity of 5-10 mm of the sinter are effectively enhanced.
In the production application of the gas injection device at the present stage, the condition that the local area of the charge level is yellow or whitish is easy to appear on the charge level of the sintering machine entering the injection cover due to the influence of various factors such as moisture, material pressing, trolley furnace bars and the like. The abnormal working condition is caused by that the ignition is not successful or the ignition degree is too high in the local area of the charge level due to the influence of various factors. The solid carbon particles in the fuel layer are not ignited successfully in the ignition process, and if the ignition intensity of the area cannot be improved in time in the situation, the sintered ores produced in the area are defective ores, so that the yield of the sintering machine is reduced seriously. If the ignition degree is too high, solid carbon particles in the material layer are ignited, and part of iron in the iron ore powder is melted and reduced, so that an over-melting layer is formed on the material surface of the area, and the air permeability is seriously deteriorated.
At present, aiming at the abnormal working condition of local appearance of the charge level caused by abnormal ignition, the charge level can be observed only by an operator on site, and then the injection amount of the fuel gas is artificially judged and integrally adjusted. Not only the labor intensity is high, but also the operation precision is low. With the coming of the artificial intelligence era, post staff reduction has become a necessary trend in the market, and a charge level identification device capable of replacing manual observation operation is urgently needed, so that the real-time online monitoring of the sintering charge level is realized.
