Description
Technical field
The utility model relates to a kind of sintering machine combustion gas blowing devices, and in particular to a kind of adaptive optimization charge level negative pressure
Combustion gas blowing device belongs to sintering technology field.
Background technique
Sintering process is the key link smelted iron in process, and principle is by various powdery iron-containing raw materials, and supplying is suitable
The fuel and flux of amount, are added suitable water, make material that a series of physical occur on agglomerating plant with after pelletizing through mixing
Variation is learned, sintering is blocking, so that being sent to blast furnace carries out the next step.
In order to reduce the coke ratio and smelting cost of blast furnace ironmaking, requirement of the blast furnace to sinter is often high-intensitive and high also
Originality.In sintering process, sinter intensity with higher, high finished product rate, the lower rate of return mine and lower are generally required
Fuel consumption.The sinter of high-intensitive 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 that one of the bottleneck for restricting development of iron & steel industry will be become.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 company 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 amount.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 porosity are effectively reinforced.It sees at present
Carry out the technology with preferable energy-saving and emission-reduction upgrading effect.
At application " sintering charge level gaseous fuel injection technology ", preferable charge level negative pressure value is the one of guarantee technology direct motion
A key factor.In general, charge level negative pressure value is influenced by main exhauster power, air leakage rate of sintering machine and bed permeability.
Blowing device structure under the prior art is as shown in Figure 1: blowing device is by blowing general pipeline, blowing branch pipe, injection tube
Row, combustion gas injection hole, blow and side seals form.Wherein blowing one end general pipeline is connected with plant area gas pipeline, another
End is connected by blowing branch pipe and injection tube row, and injection tube ranking is in blow, and positioned at sintering pallet top.Combustion gas exists
When production, blowing branch pipe is entered back into after entering blowing general pipeline from plant area's gas pipeline, injection tube is finally entered and arranges and pass through setting
Combustion gas injection hole on pipe row sprays, and dilution is mixed with air in blow, forms the Combination gas of design requirement concentration
Body, into sinter bed inside assisted sintering, side seals can effectively ensure that combustion gas will not be excessive with mixed gases in cover
To outside cover.
Suitable charge level negative pressure, it is very crucial for combustion gas blowing assisted sintering technology, and the combustion under the prior art
Gas blowout blowing apparatus, due to lacking precisely reliable charge level detection of negative pressure and adaptive-optimum control measure, therefore in production easily
There is the situation that charge level negative pressure is inadequate or excessive in blow, to will lead to following situations:
1, the bed of material can not suck combustion gas: the combustion gas sprayed from injection hole at this time is not by enough downward drafts, combustion
Gas will not according to design theory with cover in air mix after stablize flow to charge level, but it is irregular escape everywhere, so not only
After the safety accident for easily causing live combustion gas to be poisoned occurs, and combustion gas is enriched in cover, it is easy to happen kindling, damages related dress
It sets；
2, combustion gas injection technology is to no effect: since charge level negative pressure not enough causes combustion gas not to be inhaled into the bed of material, thus it is relevant
All beneficial effects cannot achieve, and cause the waste of energy medium；
3, combustion gas is pumped into too fast density unevenness: when charge level negative pressure is excessive, combustion gas just sprays out of pipe just quick
The bed of material is sucked, mixes and dilutes without air in enough time and cover, therefore easily causes gas concentration between each region of charge level uneven, from
And auxiliaring effect is adversely affected.
Under routine techniques, sintering charge level negative pressure is adjusted, mainly there are following two means:
1, main pumping frequency conversion is added: the means not only capital intensive, at high cost, and charge level negative pressure value can only be reduced, in main pumping
Fan capacity natively not enough in the case where, charge level negative pressure value can not be improved without foundation, therefore be not suitable for solving the problems, such as this technology；
2, improve air leakage rate of sintering machine: the means are all the technology that insider pursues exploration all the time, but due to setting
The variety of problems such as standby processing, production level, domestic air leakage rate of sintering machine 25% or more, can be used in effective wind of sintering always
Amount at most accounts for 75%, and effective wind rate is insufficient, and charge level negative pressure value can not also be improved, it is even more impossible to accomplish to adjust in real time, therefore is also not suitable for
In solving the problems, such as this technology.
