Description
Technical field
The present invention relates to a kind of treatment unit of blast furnace slag, in particular, the present invention relates generally to a kind of blast-furnace slag dry granulation refrigerating unit of moudle type.
Background technology
Blast-furnace slag is a kind of sub product that blast furnace ironmaking produces, and is a kind of well behaved silicate material, through processing treatment, is mainly used in the raw material of manufacture building material and chemical fertilizer.Simultaneously; In the blast furnace production process, various former, the fuel of going into stove removes acquisition molten iron (conversion pig or foundry iron) and the sub product blast furnace gas after smelting; Gangue in the iron ore; Temperature is 1450～1650 ℃ as ash content in the fuel and the flux fusion just formation liquid slag, one of which, regularly discharges from cinder notch, iron mouth.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 64kg standard coal equivalent.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 coal equivalents.
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 material of construction such as cement, and water treating method commonly used has Yin Bafa, figure daraf(reciprocal of farad), Lhasa method etc.The subject matter that this method exists has: water consumption is serious, handles 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.Handle the 1t slag and produce 800m
3Water vapor, wherein H
2S content 19mg/m
3, SO
2Content 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 higher slag of iron content is prone to set 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, and aggravating working environment causes serious environmental to pollute.Domestic blast furnace slag heat recovery only limits to the using exhaust heat of slag flushing water heating.
Shortcoming to the blast-furnace slag water quenching; The seventies in 20th century, 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; The both be earlier that liquid blast-furnace slag is broken fast, be solidified as small-particle, adopt the method for technique means recovery waste heat again.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, main drawback is that power consumption is big, equipment bulky complex, floor space are big, investment and working cost are high, and produces the secondary dust pollution.Centrifugal granulation is to rely on cf-that the high speed rotating of rotating disk or revolving cup produces with liquid blast furnace slag granulation; Have that the granulation energy consumption is low, the size distribution of grain slag is even; Be easy to realize characteristics such as sensible heat recovery; Be the hot research direction that current blast furnace slag is handled, it is theoretical many granulating to have occurred, and has obtained and partly tested achievement.Slag particle granulating cooling distance in prilling granulator is bigger, generally need 5-7 rice, and the transmission mechanism of existing prilling granulator granulation dish designs all below prilling granulator, so its transmission shaft is longer, and maintenance is very inconvenient, does not also have reliable interchangeability.
