Description

Anti- external combustion gas blowing device

Technical field

The utility model is related to a kind of sintering machine combustion gas blowing device and its combustion gas blowing method, more particularly to one kind has Firing-fighting medium is blown the anti-external combustion gas blowing device of extinguishing device and its combustion gas blowing method, belongs 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 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 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.
