Description
Technical field
The present invention relates to mining slot type liquid sealing blast cooling device and cooling means is sintered, belong to ironmaking field and ring
Guarantor field.
Background technique
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, it is how cooling to its progress protectiveness under the premise of not influencing its quality and yield rate,
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 the cooling three categories of disc type.In the market competition in later period, belt cooling technology is washed in a pan
It eliminates, remaining ring type is cooling respectively to have its advantage and disadvantage with disc type cooling technology.But it is comprehensively compared, the cold UTILIZATION OF VESIDUAL HEAT IN colder than ring of disk
Rate is more preferable (all sintering mine sensible heats are recycled), therefore disk cold is very widely used 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 ring 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 atmosphere.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 atmosphere
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, Mitsubishi and middle Sheng Gangtie, 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 cabinet 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 stock column via blinds air-intake device, passed through stock column from the bottom up and exchanged heat therewith, change
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 outlet after blower.Being formed cross section at disk cold lower tray by air sintering feed after cooling is 37 degree of stocking angle triangles
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, Mitsubishi and it is middle contain steel " air-draft-type longitudinal direction disk refrigeration technique " although having marked improvement compared with routine techniques, 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, that is, the stock column accumulated in feed chute in Fig. 1 of D1 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
When dress or just needs to rise whole sintering machine absolute altitude or just need down to dig the civil engineering plane of disk cold.Regardless of 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 "
Stream is open circuit circulation, and the direct outlet of air come out from waste heat boiler does not recycle, and causes also more than 100 degree in this way
Air sensible is wasted, and contains a large amount of little particle dust in the air of outlet, causes a degree of particle for atmosphere
Object pollution；
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 cabinet.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: the negative pressure exhausting technology taken due to " air-draft-type longitudinal direction disk refrigeration technique ", thus it
Not set sealing closure assembly 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 and dust splash.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 bad influence；
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.
For above-mentioned five strip defect, we carry out the technology and device technique of " air-draft-type longitudinal direction disk refrigeration technique "
Analyse in depth, by repeatedly groping and improve and optimizate, have developed it is a set of can not increase cooler height, distinguished and admirable closed cycle,
The patent formula technology that environmental pollution is substantially alleviated by sinter high yield rate, machine, makes every effort to effectively solve of the existing technology
Problem contributes for sintering process energy conservation and environmental protection index.
