Description
Technical field
The present invention relates to a kind of molten slag dry granulation device, belong to industrial waste residue disposal and utilize technical field.
Background technology
Slag is the high temperature producing in burning, metallurgy or chemical process, the trade waste of molten state, as liquid blast furnace slag, slag, copper ashes, phosphorus slag etc., is wherein containing abundant sensible heat resource.Liquid blast furnace is a kind of typical slag, and China's annual blast furnace slag generation number is in hundred million tons, enormous amount.Often adopt at present wet processing.But liquid blast furnace temperature, between 1350 DEG C to 1500 DEG C, has very high heat recovery and is worth.And cooling rear 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.The blast furnace slag of quenching owing to having little time to form crystallization and form the amorphous substance of a large amount of glassy phases in cooled and solidified process rapidly, has higher hydration activity especially, is the high quality raw material of producing the material of construction such as cement, has the huge market requirement.
The liquid blast furnace dry granulation and the sensible heat recovery method that have occurred at present, more representational have wind quench method and a centrifuging.The wind method of quenching is to produce with high-power granulation blower fan that high velocity air dispels, granulation liquid blast furnace; its main drawback is that power consumption is large, equipment bulky complex, floor space are large, investment and working cost high; in the time of liquid blast furnace fluctuations in discharge; wind speed and air quantity are difficult for coordinating, and a large amount of cold wind enters system and also reduced the quality of waste heat.Centrifuging is to rely on the centrifugal force of rotating disk or the generation of revolving cup high speed rotating by liquid blast furnace slag granulation; although do not need the such highly energy-consuming equipment of granulation blower fan; the size distribution of grain slag is also more even; but at high temperature the reliability of the granulating device of high speed rotating is poor; in addition the temperature of granulation effect liquid towards blast furnace slag and fluctuations in discharge are comparatively responsive, only depend on adjusting rotary speed effect unsatisfactory.
Summary of the invention
The purpose of this utility model is in order to solve prior art defect, and a kind of molten slag dry granulation device is provided.
The technical solution adopted in the utility model is:
Molten slag dry granulation device, is characterized in that: described device comprises cooling room, slag director, Rotor Spinning System, pulsing jet system; Described slag director is arranged on cooling room top, and the outlet of slag director is positioned at cooling room top center; Described Rotor Spinning System is by forming around revolving cup and the rotating-cup driving device of vertical turning axle rotation; Pulsing jet system comprises at least one group of nozzle and pulse valve, and jet exit is towards revolving cup, and jet exit is lower than revolving cup upper surface, and the angle α of jet exit medullary ray and cooling room vertical center line is 30-75 °.
In technique scheme, when described nozzle and pulse valve group are more than two, are concentric circles and are evenly arranged around the vertical turning axle of revolving cup.The nozzle ejection of described pulsing jet system be that pressure is the pressurized air of 0.2MPa～2.0MPa or the water vapour that pressure is 0.2MPa～4.0MPa.
The utility model compared with prior art has the following advantages: combine the advantage of centrifugal revolving cup and high-speed pulse jet, can obtain again more excellent granulated slag when having reduced energy consumption.
