Description
Technical Field
The utility model relates to a flue gas dust removal field, concretely relates to ferrosilicon stove waters indisputable flue gas collection processing apparatus.
Background
Ferroalloys are one of the essential important raw materials for the steel industry. The ferroalloy industry in china has developed rapidly over forty years after 1949, as the steel industry develops. At present, China has 1000 seats for various large, medium and small ferroalloy electric furnaces. The ferroalloy production capacity exceeds 300 million tons. The product not only meets self-sufficiency, but also is exported to the international market. The environmental protection and the comprehensive utilization of the ferroalloy industry in China are still in a relatively laggard state. Most of the silicon iron electric furnaces are of an open furnace type and a semi-closed cover type, only part of the large electric furnaces are provided with smoke dust purification facilities, and most of the medium and small electric furnaces do not have any dust removal facilities. Along with the enhancement of national environmental protection, each enterprise begins to equip a flue gas purification system. The smelting process of the ferroalloy comprises the following steps: the electric furnace is used for continuous smelting, the furnace charge is added in batches, iron is poured discontinuously, and the iron slag flows together. In the smelting process, the waste gas generated by the electric furnace mainly comprises: the reducing agent carbon reacts with oxygen to generate CO and CO2 in the electric furnace molten pool under high-temperature electric heat; the alkaline metal furnace burden in the molten pool is gasified at high temperature, the molten metal is oxidized or directly evaporated into waste gas (then cooled into solid particles), and the metal or hot air flow which is not completely combusted, such as coke powder, mineral powder and the like, is gasified and evaporated is carried out of the molten pool and enters the waste gas; air entering from the opening. These substances constitute the smoke, which we often see.
In the ferroalloy smelting process, the flue gas amount, the flue gas components and the flue gas temperature are constantly changed: the smoke volume is generally smaller in the front and rear periods and maximum in the middle; the smoke concentration is higher in the early and middle stages (because charging is needed in the early stage and furnace charge is needed in the middle stage), and lower in the later stage; the flue gas temperature increases with the temperature of the molten bath. The dust content of the furnace gas is 90-175 g/Nm3, 200-300 kg of dust is generated in smelting of each ton of ferroalloy, and more than 80% of dust with the particle size of less than 1.0 mu m is generated. The dust content of the smoke is generally 1.6-2.69 g/Nm3, and the dust content is 2.1-4.8% when the furnace is pounded. The bulk density of the dust is 0.22 to 0.3t/m 3. The dust particles smaller than 1 μm occupy a large proportion, so that the dust cannot be treated by the common dust removal technology. The temperature of the furnace gas is generally 500-700 ℃, and when the furnace gas is subjected to fire, slag turning and collapse, the temperature of the furnace gas can reach over 1000 ℃. The flue gas temperature after the furnace gas is mixed with the air entering from the outside of the cover is determined by which flue gas purification mode is adopted: when the heat energy recovery for recovering the sensible heat of the flue gas is adopted, the temperature of the flue gas can be 800-900 ℃; if the cooling flue gas is adopted without recovering waste heat, the temperature is generally 500-600 ℃; when the semi-closed cover is adopted for smelting ferrosilicon, the temperature of the flue gas is controlled to be about 450 ℃. The control of the flue gas temperature mainly depends on the adjustment of the amount of air entering from the outside of the cover and the air cooling through the cooler. As the viscosity of the dust is greatly increased when the temperature of the flue gas is reduced, the temperature of the flue gas should be controlled to be between 150 and 210 ℃ as the best.
With the promulgation of various national environmental laws and regulations, the environmental standard is continuously improved, and the environmental protection pressure of ferroalloy enterprises is continuously increased. All aspects of pressure are on the way to force enterprises to develop towards compliance. Enterprises can meet the increasingly strict requirements of the current environment administration law enforcement and supervision only by actively implementing various environmental protection compliance works, environmental law risks are prevented, and more advantages are gained in market competition. In the production process of the traditional submerged arc furnace, the high-temperature molten iron produced in the furnace is required to be poured into an appointed iron casting pool or an appointed casting ingot mould through a ladle, and the high-temperature molten iron is splashed and oxidized after being contacted with a cold container in the pouring process to form smoke with dust. The common treatment method for the smoke in domestic and the same industries comprises the following steps: the control equipment manually operates the upper computer or the operation button to start the equipment to collect dust when the pouring is started, and manually operates the equipment to shut down again after the pouring is finished, so that the labor force is increased, the equipment is shut down or the residual dust collecting equipment is still in operation when residual dust exists, and the high-efficiency utilization of the equipment cannot be achieved.
