Description
Technical field
The utility model is related to a kind of sintering machine combustion gas blowing device and its combustion gas blowing methods, and in particular to one kind is based on
The combustion gas of charge level video identification is blown adaptive controller, 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 suitable
The fuel and flux of amount, are added 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 to be sent to blast furnace.
In order to reduce the coke ratio and smelting cost of blast furnace ironmaking, 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 lower rate of return mine and lower
Fuel consumption.The sinter of high intensity 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 will be as one of the bottleneck of 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 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 companies exploitation comes into being, former
Reason is to be diluted to combustible concentration lower limit gaseous fuel below by being blown above the sintering charge level of a distance after ignition furnace,
Make its combustion heat supplying in sinter bed, 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 mine temperature-time is extended, so that the intensity of sinter and 5~10mm porositys are effectively reinforced.It sees at present
Carrying out the technology has preferable energy-saving and emission-reduction upgrading effect.
Blowing device structure under the prior art：Blowing device is by injection manifold, injection branch pipe, injection tube row, gas injection
Aperture blowing, blow and side seals form.Wherein injection one end manifold is connected with plant area gas pipeline, and the other end passes through injection
Branch pipe and injection tube row are connected, and injection tube ranking is 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 manifold, finally enters injection tube row and by being arranged on pipe row
Combustion gas injection hole sprays, and with air mixed diluting in blow, the mixed gases of design requirement concentration is formed, 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 is in production application at this stage, due to by many factors shadow such as moisture, binder, grate bar
It rings, the case where charge level regional area whitens is susceptible into the sintering machine charge level in blow.Occur the unusual service condition be because
It is charge level regional area due to being influenced by many factors, igniting degree too, has not only lighted the solid carbon particles in the bed of material,
And a part of iron in Iron Ore Powder has been subjected to melt and reduce, and the charge level in the region is caused to form melting layer, and gas permeability seriously becomes
Difference.
It is directed to the operating mode that this abnormal ignition causes charge level part gas permeability to be deteriorated at present, the prior art does not have any processing
Means, after can only watching charge level by operative employee scene, the artificial manifold valves for judging and integrally turning down combustion gas blowing device are opened
Degree, does so and has the following defects：
1, it is improper to be easy to cause valve adjustment：Melt situation due to lacking to cross for charge level and calculate that combustion gas sprays into decrement and is
System model, so easily causing the amplitude closed when artificially adjustment combustion gas blowing device header valve door aperture too small or mistake
Greatly.If amplitude is too small, then combustion gas spray volume crosses that melting material face region is most with respect to this, and taking out the combustion gas that do not go down can be gradually in cover
Enrichment, finally causes firing accident.If amplitude is excessive, then combustion gas totality spray volume reduces too much, for a long time can be to combustion
Gas blowout blows assisted sintering effect and causes serious negative effect；
2, operative employee's labor intensity is excessive：Due to lacking the means and device of automatic monitoring charge level situation, operative employee must not
Not while handling other busy work, periodically or non-periodically to carrying out burden level monitoring on burden level monitoring platform.So not only
The labor intensity of operative employee is improved, and since the monitoring of operative employee is not continuous, many non-health (cross and melt) charge levels do not have
It is detected, serious negative effect is also brought to the steady production of combustion gas blowing device in this way.
