Description
Technical field
The present invention relates to a kind of blast furnace slag treatment device, particularly relate to a kind of expansion slag bead casting drum for blast-furnace slag dry granulation technique.
Background technology
Blast-furnace slag is a kind of well behaved silicate material, by processing, can be used as the raw material of producing material of construction and chemical fertilizer, meanwhile, liquid high temperature furnace slag temperature is between 1350 ℃ to 1500 ℃, belong to high-grade residual heat resources, there is very high recycling and be worth.The liquid blast-furnace slag of China mainly adopts flush slag quenching at present, and the blast-furnace slag after water-cooled can be used for manufacturing the material of construction such as cement, and the subject matter that water cooling exists has: water consumption is serious, processes 1 ton of slag water consumption per ton; In water cooling process, produce a large amount of hydrogen sulfide and sulfur oxide gas enters atmosphere with water vapour, cause environmental pollution, process slag per ton and produce 800m
3water vapour, wherein H
2s content 19mg/m
3, SO
2content 4.3mg/m
3; The waste heat of slag is not effectively recycled; Grain slag water ratio is high, as cement raw material, still needs drying treatment, need to consume certain energy; Investment and the running cost of system are high, and the blast furnace that day output is 2500 tons will be built two cover flush slag equipment, and construction investment is 40,000,000 yuan of left and right; In flush slag process, the slag that iron content is higher easily sets off an explosion; And the purposes of grain slag is more single.
Shortcoming for blast-furnace slag water cooling; abroad the begun one's study method of dry type chilling granulation blast-furnace slag of 20 century 70s; mainly contain wind quench method and centrifugal granulation method; both first by liquid blast-furnace slag quick crashing, be solidified as small-particle, then adopt technique means to reclaim the method for its waste heat.The wind method of quenching be with high-power granulation blower fan produce high pressure, high velocity air by slag stream dispel, the method for granulation, main drawback is that power consumption is large, equipment bulky complex, floor space are large, investment and working cost high.Centrifugal granulation method is to rely on centrifugal force that the high speed rotating of rotating disk or revolving cup produces by liquid blast furnace slag granulation; although do not need the such highly energy-consuming equipment of granulation blower fan; and the size distribution of grain slag is also less; but at high temperature the mechanical reliability of high speed rotating granulating device is poor, it also needs to be confirmed to the adaptability of load change.
It is low that the applicant of present patent application has invented a kind of energy consumption; water consumption is little; noxious gas emission is little; blast-furnace slag dry granulation and waste heat reclaiming process that waste heat recovery rate is high; this technique is that the mode by impelling makes the less solid particulate of the cooling formation particle diameter of slag pearl after air-breathing expansion; and obnoxious flavour is wrapped in particle, then by interchanger and solid particulate, carry out heat exchange.The first step of this technique is that blast-furnace slag is derived from blast furnace, slag is fully contacted with air, in the situation that passing into a small amount of water, make the quick air-breathing expansion of slag cooling, form irregular slag pearl, in order to make the further particle of cooling and formation rule of slag pearl, just need a kind of equipment of special use, by the slag bead casting after air-breathing expansion in air, make the slag pearl profile of cooling and formation rule awing, also will guarantee that this equipment also can steady running under hot environment.
