Description
Technical field
A kind of sintering machine combustion gas blowing device and its combustion gas blowing method are the utility model is related to, more particularly to one kind can be certainly
The sintering machine blowing device and its blowing method of regulation blowing starting point are adapted to, belongs to sintering art.
Background technology
Sintering process is to smelt iron a key link in flow, and its principle is that various powdery iron-containing raw materials, supplying is suitable
The fuel and flux of amount, appropriate water is added, makes material that a series of physical occur after blended and pelletizing on agglomerating plant
Change 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 sintering deposit is often that high intensity and height are gone back
Originality.In sintering circuit, typically require that sintering deposit has higher intensity, high finished product rate, the relatively low rate of return mine, and it is relatively low
Fuel consumption.The sintering deposit 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 requirement is by as one of bottleneck for restricting 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 considered from environmental protection angle, reduces sintering solid fuel this consumption ratio with reducing blast furnace burden
Fuel ratio turns into the urgent need of ironmaking technology.
Under this overall situation, " the sintering charge level gaseous fuel injection technology " of Japanese JFE companies exploitation arises at the historic moment, and it is former
Reason is that the gaseous fuel of below combustible concentration lower limit is diluted to by being blown above the sintering charge level of the latter segment distance of ignition furnace,
Make its combustion heat supplying in sinter bed, so as to reduce the solid carbon dosage and CO in sintering deposit production2Discharge capacity.Meanwhile
Because 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 sintering deposit and 5~10mm porositys are effectively strengthened.See at present
Carrying out the technology has preferable energy-saving and emission-reduction upgrading effect.
Blowing device structure under prior art：Blowing device is by being blown house steward, injection branch pipe, injection tube row, gas injection
Aperture blowing, blow and side seals form.Wherein it is blown house steward 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 is ranked in blow, and positioned at sintering pallet top.Combustion gas production when, from
Plant area's gas pipeline enters back into injection branch pipe after entering injection house steward, finally enters injection tube row and by being arranged on pipe row
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 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, raw meal particle size, point in material
The fluctuation of the duty parameters such as fire intensity, large flue negative pressure, causes combustion zone after charge level is formed, and smoothly can not evenly move down.
By taking certain domestic 360 flat sintering machine of steel as an example, its 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 chassis 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, now
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, so as to cause auxiliaring effect to be deteriorated, auxiliaring effect can be lost when serious.
