Description
Technical field
The utility model relates to a kind of combustion gas blowing devices, and particularly a kind of sintering machine combustion gas blowing device, belongs to
Sintering art.
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 that blowing 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, make its combustion heat supplying in sinter bed, process diagram is as shown in Figure 1.It is raw that the technology can reduce sinter
Solid carbon dosage and CO2 discharge amount in production, simultaneously as the burning of gaseous fuel broaden sinter bed production when

End is connect with piston, and the other end is stretched out from one end of combustion gas injection tube.Transportable piston is equipped in combustion gas injection tube, mainly
Play two: 1, when being produced using the blowing device of the utility model, that due to blowing is combustion gas, combustion gas Zhang Biran
There are impurity etc., are used for a long time, and squit hole is easy to be washed away by crude gas the case where forming the blocking of tar dirt, reciprocating jet dress
The piston cycle set is reciprocating to be moved in combustion gas injection tube, and injection hole blocks closing by piston cycle, therefore does not have length
Phase is washed away the case where forming tar dirt appearance by crude gas, even if occurring, the piston of reciprocating movement can also be formed just in dirt
Phase is pulverized cleaning when not having intensity still, so compared with the prior art, injection hole is not easy to be blocked, and the service life is longer；
2, charge level coal gas is blown more evenly: since when being produced using the utility model, injection hole is periodically blocked envelope by closure plate
Close, therefore cause in casing coal gas and periodically sprayed out of different spray orifice, thus effectively prevent the prior art due to
Coal gas unevenness situation caused by coal gas source distance is different, thus at effective guarantee charge level coal gas blowing amount uniformity coefficient,
And then effectively ensure that coal gas is inhaled into the even concentration and auxiliaring effect of the bed of material.
In the present invention, the other end of push-pull rod is stretched out from one end of combustion gas injection tube, guarantees push-pull rod and combustion gas
Injection tube link position is to be flexibly connected and it is necessary to be sealed set, that is to say, that combustion gas will not be from push-pull rod and gas injection
The leakage of blowpipe link position.
In the present invention, driving device can be set in the outside of seal closure, also can be set in seal closure
Side is designed according to needs of production.Driving device is electric driving device commonly used in the prior art or pneumatically activated
Device.
In the present invention, the device not being illustrated is device common in the art, is the skill of this field
Equipment known to art personnel.
In the present invention, the length (or running length of sintering pallet) of sintering machine is 50-160 meters, preferably
It is 70-140 meters, preferably, 80-130 meters, 90-120 meters more preferable.
In the present invention, the diameter of combustion gas injection tube is less than or equal to the diameter of combustion gas blowing branch pipe.(each) combustion
The quantity of injection hole is 1-500, preferably 5-400, more preferably 10-200 on gas blowout blowpipe.Preferably, combustion gas injection tube
On direction of the injection hole towards sintering pallet, that is to say, that the bottom position of combustion gas injection tube is arranged in injection hole.
In the present invention, seal closure and blow are general, and combustion gas injection tube, combustion gas injection tube row, injection tube are general,
Expression is the same component.
Compared with prior art, the sintering machine combustion gas blowing device of the utility model has following advantageous effects:
1, combustion gas injection tube is changed to positive arrangement, perpendicular to the traffic direction of sintering pallet so that it is same into
Combustion gas blowing amount above sinter on the sintering pallet of degree is consistent, guarantees that the gas volume at charge level is uniform, so that
The gas concentration for being inhaled into the bed of material is consistent, to guarantee assisted sintering effect；
2, injection hole is not easy to plug: when being produced using the utility model, injection hole by piston cycle due to being hidden
Gear closing, therefore do not have and washed away the case where forming tar dirt appearance by crude gas for a long time, even if occurring, the piston of reciprocating movement
Also cleaning can be pulverized when dirt forms initial stage, still do not have intensity, so compared with the prior art, injection hole is not easy to be blocked
Plug, the service life is longer；
3, charge level coal gas is blown more evenly: since when being produced using the utility model, injection hole is by the closure plate period
Property block closing, therefore cause in combustion gas injection tube coal gas and periodically sprayed out of different spray orifice, thus effectively prevent
Prior art coal gas unevenness situation as caused by different from coal gas source distance, so that coal gas is blown at effective guarantee charge level
The uniformity coefficient of amount, and then effectively ensure that coal gas is inhaled into the even concentration and auxiliaring effect of the bed of material.
