As shown in Figure 1, a kind of design of current recycle fluid-bed boiler slagging mouth are as follows: four feeds are arranged in stokehold
Mouthful, design two normal round slag mouths 1 and an accident slag tap 2, the diameter of round slag mouth 1 are on air distribution plate a
273mm, the diameter of accident slag tap 2 are 273mm.As shown, being additionally provided with blast cap b on air distribution plate a.In actual moving process
In, all there is a problem that in terms of slag certain: the blocking of air distribution plate slag mouth, slag is unsmooth, so as to cause fluctuation of service.
To better ensure that function smoothly, through furtheing investigate, transformation is optimized to boiler slag mouth, using multiple spot slag
Scheme, it may be assumed that cancel accident slag-drip opening, one normal slag mouth of corresponding arrangement, slag mouth are changed to width below each material inlet
Degree is 250mm, and length is the square orifice of 420mm.After Optimizing Reconstruction, four slag mouths carry out slag simultaneously, effective guarantee operation
Period slag continues unimpeded.
As shown in Fig. 2, the utility model is to be disposed with rectangular slag-drip opening 11 on air distribution plate a ', slag-drip opening 11 is corresponding
It is arranged in the lower section of material inlet (being not shown in the figure, before material inlet is arranged in boiler), that is, each slag-drip opening 11 and each material inlet
It is corresponding in position.Wind cap b ' is provided with around slag-drip opening 11, wind cap b's ' is provided with conducive to deslagging.In pot
During the operation of furnace, wind cap b ' orientation blows clinker in boiler, so that dust or leaf of lighter in weight etc. are to moving up
It is dynamic, it does not fall at slag-drip opening 11, only the slag of heavier-weight can be discharged by slag-drip opening 11, so as to avoid the row on air distribution plate
The blocking of cinder notch 11, the problems such as slag is unsmooth, the problem of further avoiding the fluctuation of service of boiler.The utility model passes through increasing
Add the opening size of slag-drip opening 11, while wind cap is arranged near slag-drip opening 11 in setting near slag-drip opening 11
Quick slag thus may be implemented in b ', so that slag is unobstructed, so that boiler is stable.
In order to enable above-mentioned scheme can implement or better implementation, the utility model has also done improvement below: 1,
Set curved for the water screen tube c ' of the utility model, due to the scum pipe of slag-drip opening connection, scum pipe surrounding is annular
Straight water screen tube c ' if straight tube water screen tube c ' can conflict with header, therefore is become bend pipe by header.2, entire water cooling wind is replaced
Room, due to overall variant, four slag mouths are carried out according to actual size.3, front wall lower header is replaced, the bottom Hou Qiang collects above and below
Case increases front wall bottom lower header totally four headers newly.4, increase slag nozzle nearby big blast cap, wind cap and blast cap set
Pipe, lower part is sealed with steel plate.5, replacement down-comer distributes header to water-cooling wall front wall lower header, rear wall lower header, side wall next part
Case is lauched connecting tube.6, slag dropping tube is replaced, that is, using the slag for the material production that castable refractory and heat resisting cast steel combine
Pipe, replacement manual inserting plate door, increase slag mouth and pressgang able-bodied men.7, increase the corresponding slag cooler of slag mouth and transportation system.
In one example, the length of the square aperture of slag-drip opening 11 is 420mm-450mm, and the width of slag-drip opening 11 is
250mm-280mm.As a preferred example, a length of the 420 of the square aperture of slag-drip opening 11, width 250mm.
In one example, the quantity of slag-drip opening 11 is 4, and the quantity of material inlet is 4.
Certainly, skilled person will appreciate that dawn, the quantity of slag-drip opening 11 and the size of slag-drip opening 11 are not to limit this reality
With the condition of novel protection scope, the quantity of slag-drip opening 11 and the size of slag-drip opening 11 are also possible to other numerical value.
In one example, the surrounding of each slag-drip opening 11 arranges 10 wind caps.
In one example, large number of big blast cap is arranged on air distribution plate, it is preferable that big blast cap is the big blast cap of bell.
The similar replacement or deformation of individual part or component in this practical boiler each fall within the guarantor of the utility model
Within the scope of shield.
The utility model uses multiple spot slag scheme, it may be assumed that cancels accident slag-drip opening, corresponds to cloth below each material inlet
A normal slag mouth is set, it is 250mm that slag-drip opening, which is changed to width, and length is the square orifice of 420mm.After Optimizing Reconstruction, four rows
Cinder notch carries out slag simultaneously, and slag continues unimpeded during effective guarantee is run.
The utility model is illustrated through the foregoing embodiment, but it is to be understood that, above-described embodiment is
Purpose for illustrating and illustrating, and be not intended to limit the invention within the scope of described embodiment.Furthermore ability
Field technique personnel are it is understood that the utility model is not limited to above-described embodiment, and introduction according to the present utility model is also
