Description
Technical field
The present invention relates to the sintering deposit of bilateral the discharging liquid-tight envelope blast cooling device of slot type and cooling means, belong to ironmaking field
And field of Environment Protection.
Background technology
During modern sintering process, " cooling " is one of more crucial process.Sintering deposit after the roasting by sintering machine,
High temperature finished product ore deposit has been formed, how protectiveness cooling have been carried out to it on the premise of its quality and yield rate is not influenceed, can
It is enough to send into finished product ore storage bin through belt feeder, it is technology in the industry all the time while the sensible heat energy perfection entrained by it is recycled
The problem of personage constantly studies.Since 1960s, the cooling technique of sintering deposit is developed rapidly, and it mainly divides
For belt cooling, ring type cooling three major types are cooled down with disc type.In the market competition in later stage, belt cooling technology is eliminated, remaining
Under ring type cooling with disc type cooling technology respectively have its advantage and disadvantage.But Integrated comparative, the cold utilization rate of waste heat colder than ring of disk is more preferable
(all sintering mine sensible heats are recycled utilization), therefore market is using widely abroad for disk cold, this patent is also cold around disk
Machine technology is illustrated.
Disk cold technology develops since the seventies, most starts cold for transverse type disk, that is, it is outside from the inner ring of disk cold to cool down wind
Circulation is moved, and is horizontally through the bed of material to be cooled and is exchanged heat with it, and the cooling wind after having exchanged heat is directly outer to drain into air.So do both without
Ji also not environmentally, optimizes by continuous research for many years, and newest disk cold technology is that Mitsubishi Hitachi carries with middle Sheng steel
" the air-draft-type longitudinal direction disk refrigeration technique " gone out.This technology uses exhausting, cooling wind is pumped into material bottom to be cooled from air, then
Up longitudinally through the bed of material, finally from bed of material top, blowout enters subsequent handling.The program is compared with the scheme most started,
There is very big optimization and progress, described in detail below for the program.
JP2008232519A (Hitachi of Mitsubishi and middle Sheng steel, call D1 in the following text) discloses the longitudinal disk refrigeration technique of air-draft-type, referring to wherein
Fig. 1：Heat sinter enters feed chute from sintering machine tail clan, and the stock column of certain altitude, such side are piled into chute
Face is to play a part of uniform blanking, is on the other hand to play material envelope to prevent charging aperture string wind action.Mineral aggregate continues downward pass through
Enter after hood in disk cold casing, push into the stock column of certain altitude.At the same time, influenceed by the negative pressure of air exhauster, disk is cold
Air near machine can be inhaled into stock column via blinds air-intake device, exchanged heat therewith through stock column from the bottom up, after heat exchange is finished
Air passed from stock column top surface and enter air outlet, be sent to gravitational precipitator and waste heat boiler, eventually pass outer after air exhauster
Row.Sintering feed after being cooled down by air forms annular accumulation of the cross section for 37 degree of stocking angle triangles at disk cold lower tray
Area, when being turned to discharge zone, sintering feed is scraped by scraper plate device, is completed refrigerating work procedure and is entered next process links.
Hitachi of Mitsubishi is with middle " the air-draft-type longitudinal direction disk refrigeration technique " for containing steel although more conventional technology has marked improvement, but still deposits
In following five point defect：
1) device whole height requires too high：Because " air-draft-type longitudinal direction disk refrigeration technique " takes exhausting mode, so must enter
Material mouth position sets material envelope, that is, the stock column accumulated in D1 Fig. 1 in feed chute, and material envelope height is with disk cold casing
1.2~1.5 times of stock column height are standard.The height of whole series of discs device for cooling is thus virtually increased, will in construction and installation
It is accomplished by rising whole sintering machine absolute altitude, otherwise it is accomplished by down digging the civil engineering plane of disk cold.No matter which kind of side selected
Formula, can all cause a high cost of investment, not calculate very much in economic indicator；
2) distinguished and admirable open circuit circulation causes utilization rate of waste heat low and pollutes environment：Distinguished and admirable due to " air-draft-type longitudinal direction disk refrigeration technique " be
Open circuit circulation, the directly outer row of air come out from waste heat boiler does not recycle, and so causes the air spent also 100 more
Sensible heat is wasted, and contains a large amount of little particle dust in the air arranged outside, and a certain degree of Particulate Pollution is caused for air；
3) material serious wear at charging aperture：Because " air-draft-type longitudinal direction disk refrigeration technique " sets material envelope at feed chute, therefore expect
In envelope bottom and disk cold casing one section of frictional distance is had between charge level upper strata.Now sintering feed is extruded in high temperature and top stock column
Double-deck bad working environments under, be easy to when being rubbed efflorescence become it is broken, so as to reduce the yield rate of sintering machine；
4) environmental pollution is more serious：Due to the negative pressure exhausting technology that " air-draft-type longitudinal direction disk refrigeration technique " is taken, so it is in casing
It is not provided with sealing closure assembly at lower tray.So when sintering deposit is scraped by doctor blade device, easily cause a large amount of fine particles with
Dust splashes.And once air exhauster breaks down and overhauled, the material dust pushed around disk cold can all enter air, to machine
Other operating environment is caused and its ill effect.
5) the waste heat boiler thermal efficiency is not up to highest：Due to " air-draft-type longitudinal direction disk refrigeration technique " not pass the air of the bed of material according to
Wind-warm syndrome is precisely classified, but is all mixed into waste heat boiler, so when low-temperature zone outlet wind-warm syndrome is too low, will certainly be dragged down
Into the air themperature of waste heat boiler, so as to reduce the thermal efficiency value of waste heat boiler.
For above-mentioned five strip defect, we are goed deep into the technology to " air-draft-type longitudinal direction disk refrigeration technique " with device technique
Analysis, by repeatedly groping and improving and optimizating, have developed a set of can not increase cooler height, distinguished and admirable closed cycle, sintering
The patent formula technology that environmental pollution is significantly alleviated by ore deposit high yield rate, machine, makes every effort to effectively solve the problem of prior art is present,
Contributed for sintering circuit energy-conserving and environment-protective index.
