Description
Technical field
This utility model relates to a kind of chiller and using method thereof, is specifically related to a kind of vertical cooling dress in mining and metallurgy field
Put and using method, particularly to a kind of DRI vertical water-wind method for composite cooling and device thereof.
Background technology
DRI (DRI-Direct Reduced Iron is called for short DRI) refers to essence iron powder or ferrum oxide warp in stove
The low-carbon (LC) cellular material that low-temperature reduction is formed, its chemical composition stability, impurity content is few.Enter with oxide pellet with sintering deposit
Blast furnace ironmaking is different, and direct-reduction iron mine major part is used as the raw material of electric furnace and pneumatic steelmaking, can increase steel uniformity, also may be used
Improve the physical property of steel, thus reach to produce the purpose of high-quality steel.DRI is not only replacing of high-quality steel scrap
For thing, or produce the requisite high-grade materials of high-quality steel.
The technological process of production of DRI is divided into seven operations: dispensing, be dried, crush, mix, preheat, roasting with
Cooling.Finished product direct-reduction iron mine after refrigerating work procedure can enter finished product ore storage bin, serves as the former of electric furnace or pneumatic steelmaking
Material.Can hold " cooling " this last to close, making the first six procedure, unlikely all that has been achieved is spoiled, final production goes out qualified, the DRI of high-quality
Finished product ore deposit, is a problem being concerned about of each technical staff.
The cooling means of DRI has two kinds the most on the market: direct contact type water cooling and indirect contact water-cooled
Method.Direct contact type water cooling refer to by by the high temperature DRI pellet (about 1400 DEG C) after roasting directly and Cold Water Exposure from
And heat exchange cooling, the typical equipments of this technology is interior shower water cooling tower, and this technological merit is that the coefficient of heat transfer is high, cooling effectiveness
Good；But DRI ore deposit is because of high-temperature quenching, it is susceptible to efflorescence thus reduces yield rate, and reduction of iron ore contacts with water and easily occurs two
Secondary oxidation, therefore do not accept for market.Indirect contact water cooling refer to by high temperature DRI pellet indirectly and Cold Water Exposure thus
Heat exchange cools down, and the typical equipments of this technology is that outer shower water rotates cooling cylinder, and this technological merit is that reduction of iron ore is not straight with water
Contact, pulverization rate is all substantially reduced with secondary oxidation rate, and yield rate is greatly improved, although the coefficient of heat transfer does not has contact method
Height, but can be made up by the method increasing heat exchange area, existing market is wide to the application of this technology.
But tradition indirect contact water cooling is horizontal outer spray water law, there is following two defect:
1.DRI process scale cannot maximize: owing to using horizontal type structure, cooling cylinder needs support roller device to support.Existing
Having DRI technique maximum-norm is 150,000 tons/year, and its cooling cylinder length has reached 35 meters, needs to arrange three pairs of support roller devices.With
The maximization of DRI process scale, the length of cooling cylinder is more and more longer, and the quantity of support roller device also can get more and more,
And support roller device too much can cause the series of problems such as load distribution is difficult uniformly, carrying roller is concentric with cooling cylinder installation settings difficulty, institute
To say that the cooling cylinder of horizontal type structure limits the maximization of DRI technique, it is impossible to adapt to the technological requirement after maximizing；
The most single methods for cooling causes cooling effectiveness low: due to outer shower water horizontal cooling cylinder technology the most solely
With water as the methods for cooling of cooling medium, although its improvement technology is by arranging Horizontal water cooling set, spiral fin etc. necessarily
Cooling effectiveness is enhanced in degree, but the overall cooling effectiveness of system or on the low side, cooling effect is not good enough.And cool down what water was taken away
Physical sensible heat cannot be recycled, and causes system entirety energy consumption index higher.
