Description
Technical field
It the utility model is related to the sintering machine combustion gas blowing device and combustion gas blowing method of a kind of sequential type, more particularly to one
The sintering machine combustion gas blowing device and its sintering process of sequential type of the kind with steam blowing equipment, belong 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 blocks removing or removing means due to lacking effective spray orifice, is given birth to for a long time
Spray orifice is easily often blocked by tar in production, so as to trigger problems with：
1. injection is uneven：In production, after tar plugs gas jet orifice, if could not effectively be removed,
The hole there is no combustion gas ejection, which results in part without gas and situation that other local combustion gas spray volumes increase, serious shadow
The uniformity of injection is rung, and then the effect that assisted sintering is blown to combustion gas brings significant negative impact；
2. safety coefficient reduces：Because tar plugs gas jet orifice, other local location combustion gas spray volumes can be caused to increase
It is more, and combustion gas its each location point injection amount before the bed of material is sprayed into be have passed through calculating (just with air mixed diluting in cover
To design concentration).Increasing for local location gas quantity can cause the position gas concentration value to steeply rise, once concentration value reaches
The lower limit of gas explosion scope, then it is very possible to trigger blast, cause serious production accident；
3rd, spray orifice blocks, and cleaning is extremely difficult.Because sintering machine is constantly run, and sintering machine internal temperature is higher by (one
As be 400-600 DEG C), if injection hole plug, it is necessary to sintering machine is out of service, with the sintering deposit in whole device and device
After cooling, injection hole could be cleaned, this certainly will influence the operation of sintering machine；Meanwhile if sintering machine is out of service, it can influence
The running of whole process, equipment will also be affected including cooler etc.；In addition, if injection hole plug, stops sintering suddenly
The operation of machine, the sintering of sintering deposit in sintering machine will be influenceed, reduce product quality.
