Description
Technical field
The present invention relates to molten slag granulation technique field, more particularly to a kind of pelletizer system for molten slag granulation
System.
Background technology
China is currently global maximum steel producing country, iron and steel output the first in the world.Chinese pig iron yield reaches within 2015
To 6.91 hundred million tons, the 60% of Gross World Product is accounted for.Chinese pig iron yield is 5.86 hundred million tons within 10 months 2016, accounts for the world total
The 60% of yield.The blast furnace slag for containing huge heat can be produced during manUfaCtUre of pig iron, the tapping temperature of blast furnace slag is general
Between 1400~1550 DEG C, slag per ton contains (1260~1880) × 103The sensible heat of kJ, equivalent to 60kg standard coals.In China
Under existing ironmaking technology, 1 ton of pig iron by-product, 0.3 ton of blast furnace slag is often produced, carried out with current 5.86 hundred million tons of China's pig iron yield
Calculate, the blast furnace slag for producing more than 1.75 hundred million tons can be converted into, its sensible heat amount is equivalent to 10,500,000 tons of standard coals.
Dry pit cooling method and flush slag method are the most common Treating Methods for BF Slag of current China.Dry pit cooling method will
The molten slag of high temperature is directly discharged into dry pit air cooling, auxiliary water cooling.The method produces a large amount of vapor when lowering the temperature, while discharging
Substantial amounts of H2S and SO2Gas, corrosion building, destruction equipment and aggravating working environment are general that the method is only used in accident treatment.
The blast furnace slag of China 90% is all using the treatment of flush slag method.Flush slag method refer to using low temperature cooling water directly with the liquid of high temperature
State slag mixes so that molten slag temperature is reduced and form glass figure's slag granules rapidly.Flush slag method is according to different
Technological process can be divided into Yin Bafa, Tula method, bottom filter method, Lhasa method, Ming Tekefa.Although flush slag technique is continued to develop,
The core of its technology still carries out water spray water quenching to high-temperature liquid state slag, and then reaches cooling and the purpose being granulated, and then carries out
Grain slag is separated, and the water of flushing cinder is recycled after precipitating filtering.Although the glass figure slag that the method is produced can be applied
Recycling is carried out in cement industry, but processing procedure wastes great lot of water resources, produces SO2And H2The pernicious gases such as S,
The high-quality residual heat resources contained by high-temperature liquid state slag can not effectively be reclaimed.
During blast furnace slag dry method centrifugal granulation, liquid slag drops onto the disc surfaces by rotating at a high speed, in centrifugation
It is thrown out of in the presence of power and frictional force, droplet is formed in the presence of molten slag surface tension, these small drops
Forced-convection heat transfer is carried out with the heat transfer medium (generally air) in space, radiation heat transfer is carried out with surrounding environment, make small liquid
Drop temperature is reduced rapidly, and then is undergone phase transition, and forms solidification layer.As temperature is further reduced, drop is gradually transformed into solid
Little particle.For blast furnace slag centrifugal granulation system, granulation system is the core of whole system, and pelletizer is granulation system
Core component, while be also ensure granulation stability and granulation efficiency key.Current dry granulation technology is in liquid
Generally existing problems with during state blast furnace slag granulation：
1. good cooling is not carried out to pelletizer.During liquid blast furnace slag granulation, drive of the pelletizer in motor
Lower high speed rotation.Meanwhile, the blast furnace slag of molten state is constantly dropped onto on pelletizer.The temperature of liquid blast furnace is up to 1450
DEG C, under so severe working environment, if pelletizer does not carry out good cooling, so it is easy to pelletizer
Accident.
2. the replacing difficulty of pelletizer, replacement cost are big.The main component of the liquid blast furnace of high temperature be MgO, CaO,
SiO2, temperature is up to 1450 DEG C, extremely easy that corrosion abrasion is produced to pelletizer, and pelletizer needs periodic replacement.Existing granulation
Device structure pelletizer and base are the designs of integration, and replacing difficulty is high, cost is big.
3. flow perturbation is not applied when molten slag just leaves pelletizer.The disturbance for strengthening air-flow can make liquid
State slag is broken into droplet, enhancing molten slag and the heat convection of air as early as possible, molten slag is solidified as early as possible, strengthens grain
Change effect.Conventional molten slag granulation system does not consider that not applying air-flow when molten slag just leaves pelletizer disturbs
It is dynamic, miss the inning of enhancing granulation effect.
4. without can effectively block the heat transfer of pelletizer to rotating shaft.Pelletizer and temperature are 1450 DEG C of liquid
Slag directly contact, temperature is directly connected to more than 1400 DEG C between traditional molten slag granulation system pelletizer and rotating shaft,
Heat transfer without effectively blocking pelletizer is in rotating shaft.Under the high temperature conditions, the intensity of steel shafts declines, and can make granulation
The fluctuation of service of device, influence granulation effect.
