Description
Technical field
The present invention relates to side seal device and its control methods, and in particular to a kind of combustion gas injection multilayer coordinated type side
Sealing device and its control method belong to sintering technology field.
Background technology
Sintering process is the key link smelted iron in flow, and principle is by various powdery iron-containing raw materials, and supplying is suitable
The fuel and flux of amount, are added suitable water, through mixing and making material that a series of physical occur on agglomerating plant after pelletizing
Variation is learned, sintering is blocking, and the next step is carried out to be sent to blast furnace.
In order to reduce the coke ratio and smelting cost of blast furnace ironmaking, requirement of the blast furnace to sinter is often that high intensity and height are gone back
Originality.In sintering circuit, generally require sinter that there is higher intensity, high finished product rate, the lower rate of return mine and lower
Fuel consumption.The sinter of high intensity and high reproducibility consumes less coke in blast furnace ironmaking process, to reduce dioxy
Change the discharge of carbon.In the long run consider, carbon dioxide discharge-reduction requires will be as one of the bottleneck of restriction development of iron ＆ steel industry.According to
Related data introduction, sintering account for about the 60% of industrial discharge total amount with blast furnace process CO2 emissions.Therefore, no matter from enterprise
Industry reduces cost consideration and still considers from environmental protection angle, reduces sintering solid fuel this consumption ratio and reduces blast furnace burden
Fuel ratio becomes the urgent need of ironmaking technology.
Under this overall situation, " the sintering charge level gaseous fuel injection technology " of Japanese JFE companies exploitation comes into being, former
Reason is that injection is diluted to combustible concentration lower limit or less above the pallet 1 by a distance after ignition furnace 2 of blowing device 3
Gaseous fuel, keep its combustion heat supplying in sinter bed, schematic diagram as shown in Figure 1.The technology can reduce in sinter production
Solid carbon dosage and CO2 discharge capacitys, simultaneously as the burning of gaseous fuel broaden sinter bed production when high temperature
Bandwidth, so that 1200~1400 DEG C of sinter temperature-time is extended, so that the intensity of sinter and 5
~10mm porositys are effectively reinforced.Apparently the technology has preferable energy-saving and emission-reduction upgrading effect at present, will have in the future
Good market development potential, the present invention are illustrated also for the technology.

1, sealing effect is not good enough：Due to the prior art blow side-sealing device be single-layer type side seal, i.e., only one
Layer side sealing plate, thus when negative pressure is big in cover or blow by ambient wind velocity it is big when, side seal can not just function well as
Sealing function plays counter productive so that cold wind is leak into from blow side to coal gas injection assisted sintering effect；
2, it is easy dust stratification：Since sintering mill (plant) is the more bulk material environment of more dirt, in long-time produces, side-sealing device
Easily dust stratification between sealing plate and trolley board of sintering machine, such as cannot find and be effectively treated in time, can form over time big
Block black dirt, is clipped between trolley breast plate and sealing plate, once there is the phenomenon that breast board flare due to various reasons in trolley breast plate, ash
Dirt will make side sealing plate is driven by trolley to move forwards, to drive a whole set of blowing device as trolley moves forwards,
And then causes the gas piping being connected with blowing device to be torn and rip, cause serious work safety accident.

In the prior art, the present inventor has used combustion gas blowing device in multiple engineerings, is using
In the process, since the factors such as grain size, sintering machine external environment by sinter are influenced, sintering machine blow (or seal closure)
Interior negative pressure often fluctuates, and the negative pressure that single layer side-sealing device can not adapt in blow significantly fluctuates, if suction wave
Dynamic big, often there is the case where leaking out in side-sealing device, cannot play sealing effect well.If side-sealing device leaks out,
So that cooling wind, out of, the side of seal closure enters sintering machine seal closure, which leaks out from the lower section of sintering pallet up
Side is blown, and the combustion gas of combustion gas blowing device injection is sprayed toward lower section above sintering pallet, this allows for combustion gas and leaks out
Convection current occurs so that combustion gas cannot normally enter from sinter charge level in sinter, seriously affect injection effect.In addition, should
Part, which is leaked out, can also make combustion gas be flowed toward the top of seal closure, leaked out out of seal closure, into workshop, be easy to make
At accidents such as gas poisonings.
In the present invention, side-sealing device is arranged to multiple field, 3 layers or 4 layers is generally comprised, is filled by multilayer side seal
The setting set can be good at overcoming the negative pressure in sintering machine blow (or seal closure) to fluctuate the influence brought, ensure sealing
Effect also ensures the normal operation and injection effect of combustion gas injection.Meanwhile the setting of multilayer side-sealing device, also it is avoided that
Sintering inside sintering machine external environment moderate crosswind larger impact sintering machine.
Conventionally, as sintering mill (plant) is the more bulk material environment of more dirt, and in long-time produces, side-sealing device
Sealing plate and trolley board of sintering machine between easily dust stratification, such as cannot find and be effectively treated in time, can form over time
Bulk black dirt, is clipped between trolley breast plate and sealing plate.The accumulative sealing effect for inherently influencing side-sealing device of dust, reaches
To after constant weight, the load of side-sealing device will increase so that the spacing between side-sealing device and sintering pallet becomes larger,
The occurrence of causing to leak out；In addition, if solid black dirt is formed, and it is hardened on side-sealing device, if sintering pallet goes out
The case where now deforming can drive black dirt, and to can also drive side-sealing device, and side-sealing device is integrally fixed on seal closure
, ash top can move seal closure in the case of this, first, influencing sealing effect；More seriously, due to the one of combustion gas blowing device
Part is fixedly connected with seal closure, and the mobile of seal closure can be so that sealing device displacement or mobile so that fuel gas transportation pipeline
It disconnects or fracture, consequence is hardly imaginable.In addition, side-sealing device in the prior art is fixed, if necessary to clean side
Dust on sealing device is needed after sintering pallet is out of service and cools down completely, could be cleared up, and the one of sintering machine
As be all long-play, this just brings prodigious problem to the cleaning of dust.
In the present invention, side-sealing device is arranged to it is movable, can using rotation axis connection connecting plate and force bearing plate
The angle of free adjustment sealing plate, if necessary to clear up dust, due to the setting of rotary shaft, it is only necessary to by force bearing plate to rotate
Axis is that the center of circle is rotated around connecting rod, you can so that dust on force bearing plate and sealing plate is naturally de- due to the effect of its own gravity
It falls, reaches self-cleaning effect.In addition, the setting of driving device or spring part, the rotation that force bearing plate may be implemented is automatic
It realizes, can realize intellectualized operation by control system.
The side seal device of the present invention is according to the improvement for the problem that exists in the prior art, and applicant of the present invention is
Combustion gas blowing device is used in multiple engineerings, in use, since sintering machine is used for the sintering of sinter, sinter
It generally is large-sized solid matter, the longtime running of sintering pallet inevitably will receive the impact of sinter and deform, by
In the big weight of mineral aggregate substance, sintering pallet is large scale equipment, it is impossible to often be replaced, so in the process using sintering machine
In, sintering pallet after a period of use, inevitably will appear trolley sideslip, flare deformation or inside information deformation, take
Bridge collapses equal devices, in existing technique, if the above situation occurs in sintering pallet, all without solving to do well
Method.Gently then there is the situation of leaking out in these situations, and seal closure or blow lose effect having itself, and influence combustion gas injection
Effect；It is heavy then seal closure can be caused to be sintered machine trolley and blocked, and sintering pallet is followed to move, due to blowing device be all with
What seal closure was fixedly connected, if seal closure moves, entire blowing device is inherently driven to change position, to which spray will be changed
The original structure of blowing apparatus, cause between gas pipeline and seal closure it is de- split, cause serious production accident, lose combustion completely
The meaning that gas blowout is blown.In addition, combustion gas is not blown into sinter, but it is enriched in seal closure, with the promotion of concentration,
There are the danger that combustion gas external firing is even exploded.
In the present invention, side seal device rotary adjustable structure has been changed to by the fixed of the prior art.This
The special structure of kind, in normal use and operational process, as long as the running orbit of sintering pallet is constant, entire side seal
Device can play sealing function, ensure the effect of combustion gas injection.When the running orbit of sintering pallet changes, such as
There is sideslip, flare, introversion, situations such as putting up a bridge or collapsing in sintering pallet, then sintering machine breast board inherently change it is original
Running orbit so that the gap between seal closure and trolley board of sintering machine changes, at this point, since the present invention is with rotation
It in the side seal device of shaft, can deform upon, in a certain range, if between seal closure and trolley board of sintering machine
Gap change, adjust rotary shaft, can according to the operation conditions of sintering pallet, adjust automatically sealing structure, to
Ensure sealing effect.
In the present invention, setting driving device is to facilitate the adjustment of whole device, in the process of running due to sintering machine, temperature
Degree it is higher, it is impossible to realization manually adjust, therefore, driving device can under sintering machine operating status, as needed, with
When adjust side seal device.
In the present invention, it is preferred to which it is rubber gasket sheet that scheme, which is sealing plate,.Preferably high-temperature wearable rubber gasket sheet.Using
Flexible material rubber so that the end of sealing plate is in close contact with sintering pallet lateral wall and a part for lower seal plate
