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