Detailed description of the invention
As depicted in figs. 1 and 2, a kind of saturated vapor catalytic burner for cement decomposing furnace of the present invention includes: inner sleeve 6,
Saturated vapor passage 4, catalyst tank 3, taper chamfering 8, Whirl deposite tank wing 10.Wherein, catalyst tank 3 and saturated vapor passage
4 connect, and saturated vapor passage 4 is connected with inner sleeve 6 that (saturated vapor passage 4 and inner sleeve 6 link position are positioned at inner sleeve 6
Leading portion at reducing), it is provided with taper chamfering 8 and Whirl deposite tank wing 10 at inner sleeve 6 port of export.Saturated vapor 1 is through catalyst tank 3
Two-way is divided to enter in saturated vapor passage 4.The catalyst promoting that coal dust reacts with saturated vapor is installed additional in catalyst tank 3,
Catalyst tank 3 plays regulation saturated vapor resistance and the effect of flow velocity simultaneously.In the embodiment shown in fig. 4, catalyst tank 3 is wrapped
Including a saturated vapor entrance 1, two saturated vapor outlets 12, mid portion loads catalyst 15, the shape of catalyst 15
For latticed disk, being provided with Pressure gauge in catalyst tank 3 reserves installing port 13 and draining pressure regulator valve 14 etc. simultaneously, reserved peace
The Pressure gauge of dress and draining pressure regulator valve 14 play regulation saturated vapor resistance and the effect of flow velocity.The effect of taper chamfering 8 is by force
Dispersion coal wind trend, expands the dispersion angle of coal dust, makes coal dust disperse evenly；The effect of Whirl deposite tank wing 10 is to make coal dust with saturated
Steam rotates in dore furnace, forms one " recirculating zone " at coal tube end, reaches to generate CO and H2Purpose.At Fig. 3
In illustrated embodiment, Whirl deposite tank wing 10 is equally distributed；The angle of Whirl deposite tank wing 10, depends on the selection of coal, Fig. 3
In show 8 Whirl deposite tank wings 10, angle initialization is 25 °.The effect of taper chamfering 8 is to make coal dust dispersion bigger, it is considered to
To the factors such as burner head coking, taper chamfering 8 value 13-15 °.Adjusting screw 5 He is also set up outside inner sleeve 6
Outer sleeve 7, regulation adjusting screw 5 can regulate the relative position of outer sleeve 7 and inner sleeve 6, adjust the angle of flare of coal dust with
Diffusion length etc..It is provided with coal wind entrance 2 and burner upper cover 9, due to the pipeline pipe of coal wind entrance 2 at inner sleeve 6 arrival end
Footpath is less than the caliber before inner sleeve 6 reducing, easily causes leakage, therefore sets burner upper cover 9 and seals.
The whole burner of the present invention does not has igniter, does not introduce First air, and equipment is simple, and the burner of the present invention is by three
Individual passage forms, wherein, and two-way saturated vapor passage 4 and coal wind, steam passage inner sleeve 6, and saturated vapor 1
In 3 points of two-way of catalyst tank enter saturated vapor passages 4, coal wind through coal wind entrance 2 in inner sleeve 6 arrival end enters
In sleeve 6, cross with the leading portion at inner sleeve 6 reducing of the saturated vapor 1 from saturated vapor passage 4, mixed in reducing district
Close, because pipeline reducing diameter, it may appear that the effect of " turbulent flow ", improves mixed effect.Owing to the temperature in cement decomposing furnace is higher,
Can get up with automatic combustion when pulverized coal injection is entered, therefore this burner is without igniter, and in order to realize manufacturing " water coal vapour ", also
Without introducing First air, device structure is simple, reduces manufacturing cost.The medium sprayed in inner sleeve 6 includes coal dust, sky
Gas and saturated vapor three kinds, coal wind is the mixing of coal dust and air, and in inner sleeve 6 reducing district, saturated vapor mixes with coal wind, warp
After crossing reducing, in inner sleeve 6 reducing interval, realize " turbulent flow " effect, make coal dust with air, saturated vapor degree of mixing more preferably,
Again through taper chamfering 8 and Whirl deposite tank wing 10, reaching to improve diffusance, eddy flow enters and reacts inside dore furnace, generates CO
And H2Purpose.In order to be lowered into the air capacity of dore furnace, coal wind is only strengthened mixing dynamics by saturated vapor by this burner,
Promote combustion reaction can occur under oxygen lean conditions.Described saturated vapor 1 derives from Technology in Surplus Heat Power Generation of Cement Factory main pipeline, and flow is about
20 40kg/h, pressure 0.4 0.6MPa.Because not introducing primary air, truly reach combustion with meagre oxygen, also
React, with fixed carbon, the condition of creating, so that " water gas " reaction quickly occurs for saturated vapor.This burner is sprayed
Saturated vapor catalysis burning (promoting combustion reaction can occur under oxygen lean conditions) is there is in the coal dust gone out in the dore furnace of high temperature.By
Ignition temperature in cement decomposing furnace is higher, and up to 850 900 DEG C of these scopes, combustion reaction is carried out under oxygen-lean atmosphere
Meanwhile, nor affect on heating and the catabolic process of raw material, not only reduce the generation of the fuel NO that coal dust firing generates
Amount, improves the ambient air quality in cement plant, and the reduction component produced after adding saturated vapor can reduce and more generate
NOx, reduce charges for disposing pollutants and the operating cost in whole cement plant；Meanwhile, dust is to the furnace wall of dore furnace and washing away of burner
Have also been obtained with abrasion dynamics and effectively reduce, thus improve the service life of equipment.Whole combustion process does not affect cement and decomposes
The heating of raw material and decomposition in stove.
