Description
Technical field
The present invention relates to a kind of combustion gas blowing device and its method, more particularly to a kind of rotary gas blowing device and
Its 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 endosperm is fitted
The fuel and flux of amount, add in suitable water, through mixing and making material that a series of physics occur on agglomerating plant after pelletizing
Chemical change, 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 amount with blast furnace process CO2 emissions.Therefore, no matter from enterprise
It reduces cost consideration still from environmental protection angle to consider, reduces sintering solid fuel this consumption ratio with reducing the combustion of blast furnace burden
Material is than the urgent need as ironmaking technology.
Under this overall situation, " the sintering charge level gaseous fuel injection technology " of Japanese JFE companies exploitation comes into being, former
Reason is that injection is diluted to below combustible concentration lower limit above the sintering pallet of a distance after ignition furnace by blowing device
Gaseous fuel, make its combustion heat supplying in the sintering machine bed of material.The technology can reduce sinter production in solid carbon dosage with
And CO2Discharge capacity.Simultaneously as the burning of gaseous fuel broadens high temperature bandwidth of the sintering machine bed of material in production, so
So that 1200-1400 DEG C of sinter temperature-time is extended, so that the intensity of sinter and 5-10mm porositys
Effectively strengthened.Apparently the technology has preferable energy-saving and emission-reduction upgrading effect at present, will have good market in the future and dive
Power.
Blowing device of the prior art is by injection supervisor, injection branch pipe, injection tube row, blow and side seals group
Into.In production, combustion gas enters back into injection branch pipe after entering injection manifold from plant area's gas pipeline, finally enters injection tube row simultaneously
It sprays.Combustion gas mixes after spraying in blow with air, the mixed gases of design requirement concentration is formed, into sinter bed
Internal assisted sintering.Wherein blow, side seals and sintering pallet form a confined space, ensure in cover combustion gas with
Mixed gas will not be excessive.
But there are following defects for blowing device of the prior art：
1st, combustion gas injection height differs, and each point injection is uneven.Since the blowing device under the prior art uses fixing pipe
Row's formula structure, when mounted, pipe are discharged into toward that can not fully achieve horizontal welding, even if in the installation of accurate controlled level state
In the case of, deformation during welding also easily causes injection tube to be arranged can not be vertical in strict accordance with 90 degree between the numerical value section of injection branch pipe
Straight docking.Therefore easily lead to injection tube and come the situation for being presented that one side is high, one side is low on sintering machine, directly result in injection dress
It puts on sintering machine different position injection height just to differ, be blown uneven, differ greatly.
2nd, assisted sintering effect is bad.As previously mentioned, when blowing device is blown height height on sintering machine different position
For the moment, the combustion gas of ejection does not differ into the distances travelled walked before charge level, so as to can cause combustion gas into before charge level with
The degree that air mixing is diluted differs, and in turn results in and differs into the gas concentration after charge level, can be thus blown to combustion gas
The effect of assisted sintering is negatively affected, reduction even technology for eliminating advantageous effect.
