Description
Technical field
The utility model is related to a kind of sintering machine combustion gas blowing devices, and in particular to a kind of adaptive adjustable anti-escape
Combustion gas blowing device, belongs to sintering art.
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 to be diluted to combustible concentration lower limit gaseous fuel below by being blown above the sintering charge level of a distance after ignition furnace,
Make its combustion heat supplying in sinter bed, to reduce the solid carbon dosage and CO in sinter production2Discharge capacity.Meanwhile
Since the burning of gaseous fuel broadens high temperature bandwidth of the sinter bed in production, so that 1200~1400 DEG C of burning
Knot mine temperature-time is extended, so that the intensity of sinter and 5~10mm porositys are effectively reinforced.It sees at present
Carrying out the technology has preferable energy-saving and emission-reduction upgrading effect.

The example factors such as not enough, which cause to be blown the situation that section part bed permeability is bad, charge level negative pressure value is not high enough, to be occurred, and combustion gas can horse
On up escape, do not enter and participate in assisted sintering production in the bed of material;This will result in a large amount of wasting of resources, in combustion gas resource
Increasingly precious industrial market, cannot be allowed to;
2, safety coefficient reduces:When combustion gas can not be sucked by charge level, when largely up escaping, combustion gas in workshop can be also caused
Increasing concentrations (semiclosed and sealed canister is especially apparent), and such as CO, NO gas is harmful in combustion gas, is enriched to
When a certain concentration can moment causing death, therefore result in the reduction of sintering machine safety coefficient.

The junction of bearing member is to the vertical range between the opposite other end of anti-escape plate.
The utility model introduces escaping coefficient, and the escaping coefficient refers to combustion gas and escape upwards occurs in injection produces
Possibility probability value.Real-time escaping coefficient refers to current gas and the possibility probability value escaped upwards occurs.Escaping coefficient it is big
It is small, determine that anti-escape plate should be with the size of horizontal plane angle.Escaping coefficient value is bigger, anti-escape plate angle with horizontal plane
Value is answered smaller.This is because escaping coefficient value is bigger, indicates that combustion gas Escape Probability is higher, anti-escape plate should be laid flat at this time and push down combustion
Gas to prevent it from escaping upwards, i.e., answer smaller by anti-escape plate angle with horizontal plane value;Conversely, escaping coefficient value is smaller, combustion is indicated
Gas Escape Probability is lower, at this time not influence the production of charge level exhausting, should as far as possible erect anti-escape plate, reduce exhausting resistance
Power, i.e., anti-escape plate angle with horizontal plane value should be bigger.
In the present invention, the reality that control system is measured according to charge level negative pressure monitoring device and gas flow monitoring device
When data, calculate real-time escaping coefficient, by real-time escaping coefficient calculate to obtain current anti-escape plate should with formed by horizontal plane
Then angle should go out anti-escape plate side margins according to anti-escape plate with angle calcu-lation formed by horizontal plane and need the height being elevated
Degree, the lifting driving device for finally controlling adjustable anti-release apparatus export corresponding power, are driven and lifted by level-one drawstring
Bar moves up and down, and the setting of quiet pulley then ensure that lifting rod being capable of vertical up-or-down movement.Lifting rod does vertical up-or-down movement,
Two level drawstring and three-level drawstring can be driven to move therewith, to drive anti-escape plate to rotate around bearing member is adjusted,
I.e. anti-escape plate forms corresponding angle with horizontal plane as needed.In process of production, in order to not influence sintering pallet material
The exhausting in face produces, and reduces exhausting resistance, and the angle between anti-escape plate and horizontal plane is traditionally arranged to be more than 30 °.
Compared with prior art, the utility model has the advantages that:
1, resources effective utilization:Since the utility model is in such a way that real-time monitoring, anti-escape plate real-time control solve,
Once occurring the situation that injection section part bed permeability is bad, charge level negative pressure value is not high enough, this section of anti-escape plate in production
Respective action can be made in real time, pushing down combustion gas makes it that can not escape, and with the movement of sintering machine charge level, when abnormal charge level moves
It walks, when normal charge level enters, the combustion gas being held down, which will continue to enter in the bed of material, participates in assisted sintering production, to reduce resource wave
Take;
2, safety coefficient is high:The utility model carries out the combustion gas that charge level is blown according to product practice adaptive anti-escape
The possibility that combustion gas is largely up escaped effectively has been evaded in ease control, therefore gas such as CO, NO harmful in combustion gas is also
It will not permeate into workshop condition so that the safety coefficient of sintering machine production is effectively guaranteed.
In conclusion by using the adaptive adjustable anti-escape gas injection blowing apparatus of the utility model and method, can have
Effect solves the defect of the prior art, improves the safety coefficient and resource utilization of package unit system, it is ensured that assisted sintering effect.
The utility model is more safe and reliable compared with prior art, it is anticipated that it has great potential in future market.
