Description
One, technical field
The utility model relates to a kind of gas mixed ceramic combustor that the smelting iron and steel blast funnace hot blast stove is used.
Two, background technology
Rapid economy development, for Iron and Steel Production provides good opportunity, China particularly, Iron and Steel Production has had very big development especially, but sees with regard to present circumstances, and the product steel quality of China also can not show a candle to developed country, its fundamental cause is that the wind-warm syndrome of steel-making blast furnace is low and causes, and the wind-warm syndrome of raising steel-making blast furnace is that ceramic burner decides, therefore, improve furnace temperature, just must reform ceramic burner, and the burner of use is because structural unreasonable at present, furnace temperature is low, make steel of poor quality, can not satisfy in the rapid economic development needs to the high quality iron and steel, therefore, high wind furnace is imperative with the innovation of burner.
Three, utility model content
Actual needs at above-mentioned situation and smelting high-quality steel, the purpose of the utility model just provides novel a kind of gas mixed ceramic combustor that a kind of blast funnace hot blast stove is used, can effectively improve furnace temperature, solve the problem that causes the steel quality difference in the smelting iron and steel because of furnace temperature is low, the technical scheme of its solution is, this burner is the bottom by furnace wall and interior wall every putting the blast furnace gas passage that constitutes, combustion air passage and coke-oven gas passage constitute, the stove beam is arranged at triple channel top, the blast furnace gas distribution channel that is made of furnace wall and top internal partition wall is arranged at Lu Liang top, combustion air distribution channel and coke-oven gas distribution channel, the interlaced arrangement of each distribution channel, the blast furnace gas passage communicates with the blast furnace gas distribution channel, the combustion air passage communicates with the combustion air distribution channel, the coke-oven gas passage communicates with the coke-oven gas distribution channel, the gas mixing duct that is connected with three distribution channel is equipped with on inherent three of furnace wall top above the distribution channel, the gas orifice of connection is housed above the gas mixing duct, and communicate with the combustion chamber on top, the utility model structure uniqueness, novel, sufficient combustion, the calorific value height, gas mixes, CO content is low, hotblast stove temperature raising speed is fast, send into the wind-warm syndrome height of blast furnace, the steel product quality of producing good (high-quality), cost is low, and significantly reduced pollution to environment, collect energy-conservation, environmental protection has the wide development application prospect in one.

Five, embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
Provide by Fig. 1-8, the utility model is every the blast furnace gas passage 3 that is set to by furnace wall 1 and interior wall 2, combustion air passage 4 and coke-oven gas passage 5 constitute, stove beam 6 is arranged at triple channel top, the blast furnace gas distribution channel 9 that is made of furnace wall 1 and top internal partition wall 14 is arranged at Lu Liang top, combustion air distribution channel 10 and coke-oven gas distribution channel 11, the interlaced arrangement of each distribution channel, the blast furnace gas passage communicates with the blast furnace gas distribution channel, the combustion air passage communicates with the combustion air distribution channel, the coke-oven gas passage communicates with the coke-oven gas distribution channel, the gas mixing duct 13-1 that is connected and interlocks and arrange in length and breadth with three distribution channel is equipped with on inherent three of furnace wall top above the distribution channel, 13-2, the gas orifice 12 of connection is housed above the gas mixing duct, and communicates with the combustion chamber 15 on top.
In order to guarantee result of use, insert fire-resistant casting material 7 in said blast furnace gas distribution channel 9, combustion air distribution channel 10 and the coke-oven gas distribution channel 11, it is taken the form of inclined plane with corresponding blast furnace gas passage 3, combustion air passage 4 and coke-oven gas passage 5 respectively be connected; 14 of top internal partition walls have horizontal support 8, make the stable distance of maintenance between passage and the passage.
Service condition of the present utility model is, when blast furnace gas, combustion air and the coke-oven gas passage by separately enters in the burner, and the distribution channel through communicating with each passage enters in the mixed gas duct on top again, it is even to carry out thorough mixing, gas after mixing sprays through gas orifice, enter the combustion chamber, make it perfect combustion, reach the purpose of smelting.
By said structure as can be seen, the utility model has adopted blast furnace gas, combustion air and coke-oven gas, changed general blast furnace and be the coal gas that self produces and the mode of combustion air mixed firing, on former basis, increased coke-oven gas again, increased flammable raw material, improved furnace temperature greatly, owing to adopted the structure formation of unique triple channel and three distribution channel, gas has obtained sufficient uniform mixing, sufficient combustion, the thermo-efficiency height, the energy utilization rate height, can improve more than furnace temperature 100-200 ℃ than traditional blast furnace after tested, satisfied fully smelting high-quality steel pyritous needs more than 1820 ℃, and CO content is very low in the gas of discharging, does not have the black smoke phenomenon fully, has improved the pollution problem of traditional blast furnace to air ambient greatly, because the abundant burning of fuel, improved the utilization ratio of heat energy, effectively saved the energy, according to test, energy-conservation reaching more than 30%, because under high temperature and the abundant oxygen, guaranteed the complete oxidation reduction reaction of iron ore in blast furnace, smelting speed is fast, the efficient height, thereby improved smelting output, can be up to more than 20%, and produce the fine steel.
Therefore, of the present utility model succeeding in developing is to existing creationary innovation of ceramic burner and improvement, through on probation, obtained gratifying effect, and it is applied, and must make huge creative contribution for Iron and Steel Production, and DEVELOPMENT PROSPECT is boundless.
