Description
Technical field
The present invention relates to a kind of sintering machine combustion gas blowing device and its combustion gas blowing methods, and more particularly to one kind can be adaptive
The sintering machine blowing device and its blowing method of regulation blowing starting point, belong 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 fitted
The fuel and flux of amount, add in 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 so as to be sent to blast furnace.
In order to reduce the coke ratio of blast furnace ironmaking and smelting cost, 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 relatively low rate of return mine and relatively low
Fuel consumption.The sinter of high intensity and high reproducibility consumes less coke in blast furnace ironmaking process, so as to reduce dioxy
Change the discharge of carbon.In the long run consider, carbon dioxide discharge-reduction is required one of bottleneck as restriction development of iron ＆ steel industry.According to
Related data introduction, sintering account for 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 with reducing 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 be by the way that injection is diluted to gaseous fuel below combustible concentration lower limit above the sintering charge level of a distance after ignition furnace,
Make its combustion heat supplying in sinter bed, so as 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 ore deposit temperature-time is extended, so that the intensity of sinter and 5~10mm porositys are effectively strengthened.It sees at present
Carry out the technology with preferable energy-saving and emission-reduction upgrading effect.
Blowing device structure under the prior art：Blowing device is by injection manifold, injection branch pipe, injection tube row, gas injection
Aperture blowing, blow and side seals form.It is wherein blown manifold one end with plant area gas pipeline to be connected, the other end passes through injection
Branch pipe and injection tube row are connected, and injection tube ranking is in blow, and positioned at sintering pallet top.Combustion gas production when, from
Plant area's gas pipeline enter injection manifold after enter back into injection branch pipe, finally enter injection tube arrange and pass through be arranged on pipe arrange on
Combustion gas injection hole spray, in blow with air mixed diluting, formed design requirement concentration mixed gases, into sintering
Assisted sintering inside the bed of material, side seals can effectively ensure that combustion gas will not be excessive outer to covering with mixed gases in cover.
Combustion gas blowing device under the prior art, due to can not automatic adjusument injection starting point, therefore exist in production
Following defect：
1st, easily catch fire and trigger security incident：Sintering machine is in production, often because of moisture, material size, point in material
The fluctuation of the duty parameters such as fire intensity, large flue negative pressure, causes combustion zone to can not be successfully and evenly move down after charge level is formed.
By taking certain domestic 360 flat sintering machine of steel as an example, combustion zone is after charge level generation, and 1-6 bellows are all always present in charge level position
It can not move down, just quickly be moved down after trolley goes to No. 7 bellows.Once running into this unusual service condition, combustion gas blowing device is former
The injection starting point for having design will carry out respective change, and otherwise when gas injection is blown to charge level, combustion zone is also in charge level, at this time
It may result in combustion gas to catch fire, trigger security incident；
2nd, easily cause auxiliaring effect difference or lose auxiliaring effect：When the combustion gas under unusual service condition, being ejected to charge level is caught fire
During burning, combustion gas injection ancillary technique also just loses original meaning that gas injection is entered to the intensified-sintered effect of bed of material internal-combustion
Justice is deteriorated so as to cause auxiliaring effect, auxiliaring effect can be lost when serious.
