Description
Technical field
Vertical sinter cooler and the sintering deposit cooling means with chute feeder is the utility model is related to, is belonged to
Ironmaking field and field of Environment Protection.
Background technology
During modern sintering process, " cooling " is one of more crucial process.Sintering deposit is in the roasting by sintering machine
After burning, high temperature finished product ore deposit has been formed, how on the premise of its quality and yield rate is not influenceed protectiveness cooling to be carried out to it,
Finished product ore storage bin can be sent into through belt feeder, while the sensible heat energy perfection entrained by it is recycled, is all the time
The problem of skilled worker constantly studies in the industry.Since the 1960s, the cooling technique of sintering deposit is developed rapidly, its
It is broadly divided into belt cooling, ring type cooling and disc type cooling three major types.In the market competition in later stage, belt cooling technology is washed in a pan
Eliminate, remaining ring type cooling respectively has its advantage and disadvantage with disc type cooling technology.But Integrated comparative, the cold UTILIZATION OF VESIDUAL HEAT IN colder than ring of disk
Rate is more preferable (all sintering mine sensible heats are recycled utilization), therefore market application is very extensive abroad for disk cold, and this patent is also
It is illustrated around disk cold technology.
Disk cold technology develops since the seventies, most start for transverse type disk it is cold, that is, cool down wind be out of disk cold
Ring outer shroud flows, 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 it is uneconomical or not environmentally, optimize by continuous research for many years, newest disk cold technology is Mitsubishi Hitachi with
Contain " air-draft-type longitudinal direction disk refrigeration technique " that steel proposes.This technology uses exhausting, and cooling wind is pumped into material bottom to be cooled from air
Portion, then up longitudinally through the bed of material, finally from bed of material top, blowout enters subsequent handling.The program and the scheme phase most started
Than having had very big optimization and progress, having been described in detail below for the program.
JP2008232519A (Hitachi of Mitsubishi and middle Sheng steel, call D1 in the following text) discloses air-draft-type longitudinal direction disk refrigeration technique, referring to
Fig. 1 therein：Heat sinter enters feed chute from sintering machine tail clan, the stock column of certain altitude is piled into chute, so
On the one hand it 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 continue to
It is lower to enter after hood in disk cold casing, push into the stock column of certain altitude.At the same time, by the negative pressure shadow of air exhauster
Ring, the air near disk cold can be inhaled into stock column via blinds air-intake device, exchanged heat, changed therewith through stock column from the bottom up
Air after heat is passed into air outlet from stock column top surface, is sent to gravitational precipitator and waste heat boiler, finally by taking out
By outer row after blower fan.It is 37 degree of stocking angle triangles that sintering feed after being cooled down by air forms cross section at disk cold lower tray
The annular accumulation area of shape, when being turned to discharge zone, sintering feed is scraped by scraper plate device, and completion refrigerating work procedure enters next
Individual process links.
Hitachi of Mitsubishi with it is middle Sheng steel " air-draft-type longitudinal direction disk refrigeration technique " although more conventional technology has marked improvement, but still
Following five point defect so be present：
1) device whole height requires too high：Because " air-draft-type longitudinal direction disk refrigeration technique " takes exhausting mode, so necessary
Material envelope, that is, the stock column accumulated in D1 Fig. 1 in feed chute are set in gating location, material envelope height is with disk cold case
1.2~1.5 times of internal stock column height are standard.The height of whole series of discs device for cooling is thus virtually increased, is pacified in construction
Either just need to rise whole sintering machine absolute altitude during dress, or just need down to dig the civil engineering plane of disk cold.No matter choosing
Which kind of mode is selected, a high cost of investment can be all caused, not calculate very much in economic indicator；
2) distinguished and admirable open circuit circulation causes utilization rate of waste heat low and pollutes environment：Due to the wind of " air-draft-type longitudinal direction disk refrigeration technique "
Flow for open circuit circulation, the directly outer row of the air come out from waste heat boiler does not recycle, and so causes what is spent also 100 more
Air sensible is wasted, and contains a large amount of little particle dust in the air arranged outside, and a certain degree of particle is caused for air
Thing pollutes；
3) material serious wear at charging aperture：Because " air-draft-type longitudinal direction disk refrigeration technique " sets material envelope at feed chute,
Therefore have one section of frictional distance between charge level upper strata in material envelope bottom and disk cold casing.Now sintering feed is expected in high temperature and top
Under the double-deck bad working environments of post extruding, efflorescence is easy to when being rubbed and becomes 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, thus it
It is not provided with sealing closure assembly at lower box pallet.So when sintering deposit is scraped by doctor blade device, easily cause a large amount of trickle
Particle splashes with dust.And once air exhauster breaks down and overhauled, the material dust pushed around disk cold can all enter big
Gas, is caused and its ill effect to the operating environment by machine.
5) the waste heat boiler thermal efficiency is not up to highest：Because " air-draft-type longitudinal direction disk refrigeration technique " be not the air for passing the bed of material
Precisely it is classified according to wind-warm syndrome, but is all mixed into waste heat boiler, will certainly so when low-temperature zone outlet wind-warm syndrome is too low
The air themperature into waste heat boiler is dragged down, so as to reduce the thermal efficiency value of waste heat boiler.
At present, sintering deposit cooling is mainly using the conventional belt based on strong wind rapid cooling, disposable handling cooling principle
Cooler or circular cooler.No matter which kind of type of cooling used, it is big air leak rate of air curtain to be all present in cooler, and blower fan power consumption is high, sensible heat
The rate of recovery is low, the problems such as boiler thermal output is low.In other words, in the Vehicles Collected from Market requirement with green manufacturing energy-saving to sintering production
Under increasingly stricter overall situation, originally device structure has been difficult to realize sintering mine sensible heat high efficiente callback with utilizing.
Therefore, the limitation of traditional ring type cooling or belt cooling is broken through, develops a kind of sintering mine sensible heat high efficiente callback
Technique and technical equipment, it has been the only way of sintering industry energy-conserving and environment-protective.
