Description
Technical field
The utility model is related to a kind of sinter cooler and sinter cooling means, more particularly to a kind of vertical burning of lattice
Mine cooler and sinter cooling means are tied, ironmaking field and field of environment protection are belonged to.
Background technology
During modern sintering process, " cooling " is more crucial one of process.Sinter is in the roasting by sintering machine
After burning, high temperature finished product mine has been formed, how under the premise of not influencing its quality with yield rate protectiveness cooling to be carried out to it,
It can be sent into finished product ore storage bin through belt feeder, while the sensible heat energy perfection entrained by it being recycled, be all the time
The problem of skilled worker constantly studies in the industry.Since the 1960s, the cooling technique of sinter is rapidly developed,
It is broadly divided into cooling belt, ring type cooling and disc type cooling three categories.In the market competition in later stage, belt cooling technology is washed in a pan
It eliminates, 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 disk cold is widely used general in overseas market, and this patent is also
It is illustrated around disk cold technology.
Disk cold technology develops since the seventies, most starts cold for transverse type disk, i.e., cooling wind is out of disk cold
Circumferential outer shroud flowing, is horizontally through the bed of material to be cooled and exchanges heat with it, and the cooling wind after having exchanged heat is directly outer to drain into air.It does so
Both uneconomical or not environmentally, optimize by continuous research for many years, newest disk cold technology is Mitsubishi Hitachi in
It contains " 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 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, in this way
On the one hand it is to play the role of uniform blanking, is on the other hand to play material envelope to prevent feed inlet string wind action.Mineral aggregate continue to
It is lower to enter in disk cold babinet after hood, push the stock column at certain altitude.At the same time, by the negative pressure shadow of exhaust fan
It rings, the air near disk cold can be inhaled into via blinds air-intake device in stock column, exchanged heat, changed therewith across stock column from the bottom up
Air after heat is pierced by from stock column top surface into air outlet, is sent to gravitational precipitator and waste heat boiler, finally by taking out
By outer row after wind turbine.It is 37 degree of stocking angle triangles to form cross section at disk cold lower tray by the sintering feed after air cooling
The annular accumulation area of shape, when being turned to discharge zone, sintering feed is scraped by scraper plate device, and completion cooling process enters next
A process links.
Hitachi of Mitsubishi with it is middle contain steel " air-draft-type longitudinal direction disk refrigeration technique " although more conventional technology has marked improvement, but still
So there is following five point defect：
1) device whole height requires excessively high：Since " air-draft-type longitudinal direction disk refrigeration technique " takes exhausting mode, so necessary
Material envelope is set in gating location, that is, the stock column accumulated in feed chute in Fig. 1 of D1, material envelope height is with disk cold case
1.2~1.5 times of internal stock column height are standard.The height for thus virtually increasing whole series of discs device for cooling is pacified in construction
Or just needing to rise whole sintering machine absolute altitude when dress or just needing 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, it is very not cost-effective 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 "
It is open circuit circulation to flow, and the directly outer row of the air come out from waste heat boiler does not recycle, and causes degree also more than 100 in this way
Air sensible is wasted, and contains a large amount of little particle dust in the air arranged outside, and a degree of particle is caused for air
Object pollutes；
3) material serious wear at feed inlet：Since " air-draft-type longitudinal direction disk refrigeration technique " setting material seals at feed chute,
Therefore one section of frictional distance is had between charge level upper layer in material envelope lower part and disk cold babinet.Sintering feed is expected in high temperature and top at this time
Under the double-deck bad working environments that column squeezes, it is easy to dusting when being rubbed and becomes broken, 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
Sealing closure assembly is not set at lower box pallet.In this way when sinter is scraped by scraper device, it be easy to cause a large amount of subtle
Particle splashes with dust.And once exhaust fan breaks down maintenance, the material dust pushed around disk cold can all enter big
Gas, causes the operating environment by machine and its ill effect.
5) the waste heat boiler thermal efficiency is not up to highest：Since " air-draft-type longitudinal direction disk refrigeration technique " be not the air for being pierced by the bed of material
It is precisely classified according to wind-warm syndrome, but is all mixed into waste heat boiler, it, will certainly in this way when low-temperature zone outlet wind-warm syndrome is too low
The air themperature into waste heat boiler is dragged down, to reduce the thermal efficiency value of waste heat boiler.
Currently, sinter cooling is mainly using the conventional belt based on strong wind rapid cooling, disposable handling cooling principle
Cooler or circular cooler.The sinter cooler generally existing problems with of the prior art：1, it leaks out serious, power consumption is high.
Three kinds of types of cooling are all that sinter is placed on trolley, are cooled down to sinter by air blast or exhausting, trolley and bellows it
Between difficult sealing to solve, general air leak rate of air curtain increases cooling power consumption up to 20% or more, even as high as 50%；2, heat exchange is not filled
Point.Distributary exchanges heat between sinter and cooling air in belt-cooling machine or ring cold machine, and heat transfer effect is poor；Sintered ore materials layer piling height
Low, sinter and cooling air heat-exchange time are short, and heat exchange is insufficient；3, utilization rate of waste heat is low.Cooler both ends are due to cannot
It seals and penetrates into a large amount of wild wind, since wild wind is not only to increase the power and power consumption of wind turbine without sinter bed,
And greatly reduce the flue-gas temperature after heat exchange；In existing sintering machine afterheat generating system, generally from belt-cooling machine or ring cold machine
Higher I, II section of middle temperature takes wind, and sinter and the cooling air heat-exchange end temperature difference are big, and flue-gas temperature is low, and do work capacity loss
Greatly, utilization rate of waste heat is low；4, waste heat parameter fluctuation is big.Yield, temperature and ingredient fluctuation are very big in process of production for sinter,
Larger fluctuation also occurs so as to cause Gas Parameters after heat exchange, the influence to UTILIZATION OF VESIDUAL HEAT IN is very big；5, no matter straight line cooler
Or annular cooler, bulky, investment is high, high energy consumption, plant maintenance heavy workload, and construction investment is long return period.
Therefore, it breaks through that traditional ring type is cooling or the limitation of belt cooling, develops a kind of sintering mine sensible heat high efficiente callback
Technique and technical equipment have been the energy-saving and environment-friendly only ways of sintering industry.
