Description
Technical field
The utility model relates to a kind of blast-furnace slag dry granulation device, and in particular, the utility model relates generally to a kind of high-temperature liquid state blast-furnace slag gas granulation device.
Background technology
Blast-furnace slag is a kind of byproduct that blast furnace ironmaking produces, and is a kind of well behaved silicate material, through processing treatment, is mainly used in making the raw material of material of construction and chemical fertilizer.Simultaneously, in the blast furnace production process, enter various former, the fuel of stove after smelting, except obtaining molten iron (conversion pig or foundry iron) and byproduct blast furnace gas, gangue in the iron ore, ash content in the fuel and flux merge and just form liquid slag, and its general temperature is 1450～1650 ℃, regularly discharge from cinder notch, iron mouth.Usually will be called from the slag that cinder notch is discharged " upper slag ", from be called " the lower slag " of iron mouth in company with the molten iron discharge, often be mixed with a small amount of molten iron in the lower slag.The chemical ingredients of blast-furnace slag depends on that the working of a furnace in material composition, smelt iron kind, working method and the smelting process changes.Main component is CaO, MgO, SiO in the blast furnace slag
2And A1
2O
3, accounting for more than 95% of total amount, these four kinds of compositions can determine the metallurgical performance of blast furnace slag substantially.The Flos Bombacis Malabarici vanadium titano-magnetite contains more TiO
2, the packet header baiyuneboite contains more CaF
2, with these particular iron ore smeltings, corresponding TiO in the slag
2, CaF
2More.In addition, also contain a small amount of FeO, MnO and CaS and some minor compounds in the slag, its basicity is generally 0.9～1.25.When blast-furnace smelting normally carried out, slag composition changed little, but sometimes needs to adjust in process of production charge composition, this moment the slag composition respective change, the working of a furnace changes slag composition and also can change, Feo, SiO in the slag when stove is cold
2Content can slightly have and increases.1 ton of pig iron of every production is wanted by-product 300～400kg slag, and outflow temperature is at 1450～1650 ℃, and the 1t blast furnace slag contains the heat of 1800MJ approximately, amounts to the 64kg standard coal.The blase furnace cast iron output of China in 2011 is 6.3 hundred million t, and the generation of blast furnace slag is about 2.14 hundred million t, and institute's heat content is amounted to 1,370 ten thousand t standard coals.
At present, the liquid blast-furnace slag of China adopts water quenching to produce grain slag more than 90%, and the blast-furnace slag after the water-cooled can be used for making the material of construction such as cement, and water treating method commonly used has Yin Bafa, figure daraf(reciprocal of farad), Lhasa method etc.The method Main Problems has: water consumption is serious, processes 1 ton of slag water consumption per ton, and a large amount of H that produce
2S and SO
XGas enters atmosphere with water vapour, causes environmental pollution.Process the 1t slag and produce 800m
3Water vapor, wherein H2S content 19mg/m
3, SO2 content 4.319mg/m
3The waste heat of slag is not effectively recycled; The grain slag water ratio is high simultaneously, still needs drying treatment as cement raw material, needs to consume certain energy; The investment of system and running cost are high, and the blast furnace of a daily output 2500t will be built two cover flush slag equipment, and generally about 4,000 ten thousand yuan, in the flush slag process, the slag that iron content is higher easily sets off an explosion in construction investment; And the grain slag purposes is more single.The H that produces
2S and SO
XEnter atmosphere Deng obnoxious flavour with steam, promote the formation of acid rain, the accumulation of Water Quenching Slag has taken a large amount of land areas, even sand can occur, worsens environment, causes serious environmental pollution.Domestic blast furnace slag heat recovery only limits to the using exhaust heat of slag flushing water heating.There was the report that adopts using exhaust heat of slag flushing water to solve plant area's part heating or bathroom supplying hot water in the enterprises such as Shoudu Iron and Steel Co, Ji steel, Xuan Gang, Anshan iron and steel plant, this steel, Laigang, An Gang.But this utilization only accounts for the seldom part of blast furnace slag complete sensible heat, and the waste heat recovery rate is low, only is about 10%, and is subjected to time and regional limits, and in summer with without the southern area of warming installation, this part energy can only be wasted, and therefore applies being restricted.
Shortcoming for the blast-furnace slag water quenching; 20 century 70s, the method for the dry granulation slag that begun one's study both at home and abroad mainly contains wind quench method and centrifugal granulation method; both first with liquid blast-furnace slag quick crashing, be solidified as small-particle, adopt again the method for technique means recovery waste heat.The wind method of quenching be with high-power granulation blower fan produce high pressure, high velocity air with slag dispel, the method for granulation.Centrifugal granulation is to rely on centrifugal force that the high speed rotating of rotating disk or revolving cup produces with the method for liquid blast furnace slag granulation.The method main drawback is that power consumption is large but existing wind is quenched, equipment bulky complex, floor space are large, investment and working cost are high.
