The distributing method of row cooling.The invention still further relates to the warm fraction device for discharging used in the process.
Background technology
Sintering deposit is a kind of primary raw material of blast furnace ironmaking.High temperature sintering ore deposit is iron ore, coke powder and one
A little additives etc. after fully mixed, are evenly arranged on sintering machine, and ignition furnace is by the upper table of the bed of material
Cake fires, and under suction pressure effect, burns gradually downward until bottom the bed of material along raw materials for sintering layer.
In bed of material sintering process, combustion air required during lower floor's bed of material burning to complete through oversintering
The upper strata bed of material, combustion air is usually normal temperature air herein, at the sintering deposit sintered through upper strata
Will cool down upper strata sintering ore bed during Ceng, such sintering machine sinters ore bed upper layer material layer temperature will
It is gradually lowered with sintering time, and lower floor's bed of material will gradually rise due to combustion material layer temperature, so
On sintering machine afterbody bed of material arbitrary cross-section, the temperature of Different layer of the compost height sintering ore bed is different, typically presents
Layer temperature low lower floor temperature is high, the state gradually changed with bed depth.
At sintering machine afterbody, all sintering deposits discharging under gravity in chassis, through single roll crusher
Falling in central cooler distribution device after Po Sui, sintering deposit is evenly arranged on circular cooler trolley, cooling sky
Gas enters circular cooler trolley inside from chassis bottom grate plate and carries out sufficient heat exchange with sintering deposit, and sintering deposit is cold
But cooling down air while and be heated as heat smoke, heat smoke is discharged from circular cooler trolley top.Enter ring
The mean temperature that initial temperature is whole sintering deposit in cold high temperature sintering ore deposit, central cooler is by high temperature sintering ore deposit
It is cooled to room temperature and is easy to the techniques such as follow-up screening transport.
The mode of current UTILIZATION OF VESIDUAL HEAT IN mainly arranges one or more collector mat on circular cooler trolley top will
Sintering deposit cooling procedure produces heat smoke collect, collection heat smoke feeding bootstrap system is added
To utilize.
Research shows, in sintering machine afterbody chassis, the temperature of sintering ore bed is relatively big along short transverse difference in distribution,
As it is shown in figure 1, upper surface sintering ore bed temperature has been ambient temperature, far below sintering deposit in central cooler
Unload ore deposit temperature, and lower floor's sintering ore bed temperature is due to combustion, is in the condition of high temperature.Fig. 2 is tradition
Cooling technique sintering deposit discharging schematic diagram, the sintering ore bed unification in afterbody chassis 2 ＇ of sintering machine 1 ＇ is entered
Row discharging, enters single roll crusher 3 ＇ and crushes, and utilizes sintering machine to unload after ore bucket 4 ＇ is collected,
Enter central cooler distribution device 5 ＇, utilize distribution device that broken rear sintering deposit is evenly arranged in central cooler platform
Carrying out cooling operations on car 6 ＇, this kind of mode there is problems in that
One, low-temperature sintering ore bed temperature is far below central cooler discharge temp, it is not necessary to enters central cooler and carries out
Cooling operations, tradition cooling technique adds the sintering deposit treating capacity that central cooler is unnecessary.
Its two, currently employed sintering deposit circulating cooling waste heat reclaiming process, enter circular cooler trolley cooling
The temperature of air is higher than the temperature of low-temperature sintering ore bed, so low-temperature sintering ore bed will absorb cooling sky
The heat of gas, reduces sintering deposit waste heat flue-gas temperature.
