Description
Technical field
The utility model relates to a kind of fluidized-bed combustion boiler.Specifically, the air distribution plate in the fluid bed boiler furnace of burning sludge is used to.
Background technology
At present, the air distribution plate be used in the fluid bed boiler furnace of burning sludge mainly comprises water cooled wind chamber, steel plate is arranged at water cooled wind chamber top, steel plate is evenly equipped with pore, cloth wind short tube is all had in pore, cloth wind upper end of short tube is all stretched out on steel plate, and cloth wind upper end of short tube all has blast cap, and the surrounding of blast cap is evenly equipped with one deck aperture.Steel plate under blast cap has pouring layer, and the surface of this pouring layer is horizontal plane.Surface due to pouring layer is horizontal plane, in boiler running process, the large granular materials such as the fragment of brick in mud, cement block, iron wire easily accumulate on the pouring layer below blast cap aperture, and be difficult to discharge, thus cause pouring layer and the higher even coking of fluid bed bed surface local temperature, make fluidized-bed combustion boiler be difficult to run with security and stability.Again because the aperture of blast cap surrounding is that individual layer is arranged, there is the dead angle that some are difficult to blow to wind, after burning, the slag being in dead angle place is difficult to be blown away, and is difficult to smooth discharge, and this also can affect the safe and stable operation of boiler.
Utility model content
Problem to be solved in the utility model is to provide a kind of sludge incinerator air distribution plate.Adopt this air distribution plate, the safe and stable operation of boiler can be guaranteed.
The problems referred to above to be solved in the utility model are realized by following technical scheme:
Sludge incinerator air distribution plate of the present utility model comprises water cooled wind chamber, and steel plate is arranged at water cooled wind chamber top, and steel plate is evenly equipped with pore, cloth wind short tube is all had in pore, cloth wind upper end of short tube is all stretched out on steel plate, and cloth wind upper end of short tube all has blast cap, and the surrounding of blast cap is evenly equipped with multilayer aperture.Steel plate under blast cap there is the pouring layer as fluidized bed face.Be characterized in the upper surface of described pouring layer on the left of boiler or right side be seen as V-arrangement face, to make to form angle between the upper surface of pouring layer and horizontal plane.
The upper surface of described pouring layer wherein on front side of boiler or rear side be seen as waveform face,
Take such scheme, have the following advantages:
As can be seen from the above scheme, because the upper surface of described pouring layer is V-arrangement face, make to be formed with angle between the upper surface of pouring layer and horizontal plane.Again because described multilayer aperture is in being staggered in arrangement.Utilize being staggered in arrangement of multilayer aperture on the V-arrangement inclined plane of pouring layer upper surface and blast cap, make the large granular materials of fragment of brick, cement block, iron wire and so on can under the purging of water cooled wind chamber, V-arrangement inclined plane along pouring layer surface slides in the deslagging mouth of pipe of lower, on the pouring layer that large granular materials is not easily accumulated in below blast cap aperture, avoid the generation of pouring layer and the higher even coking situation of fluid bed bed surface local temperature, thus ensure that the operation with security and stability of fluidized-bed combustion boiler.

Fig. 2 is that schematic diagram is looked on a left side of Fig. 1;
Fig. 3 is the blast cap enlarged drawing in Fig. 1.
Detailed description of the invention
As shown in Figure 1, Figure 2 and Figure 3, sludge incinerator air distribution plate of the present utility model, comprises water cooled wind chamber 1, and water cooled wind chamber 1 top is steel plate 2, and steel plate 2 is evenly equipped with pore, is all provided with cloth wind short tube 4 in pore.Described cloth wind short tube 4 upper end is all stretched out on steel plate 2, and cloth wind short tube 4 upper end is all provided with blast cap 3, and steel plate 2 upper under blast cap 3 has the pouring layer 5 as fluidized bed face.The surrounding of described blast cap 3 is processed with three layers of aperture 7, in being staggered in arrangement between the levels in described three layers of aperture 7.
The upper surface of described pouring layer 5 is approximate V-arrangement face on the left of boiler or viewed from right side, and viewed from the front side or right side of boiler, be waveform face, thus makes to form angle between the upper surface of pouring layer 5 and horizontal plane, and wherein, described angle is 15 degree.Utilize being staggered in arrangement of multilayer aperture 7 on the V-arrangement inclined plane of pouring layer 5 upper surface, waveform face and blast cap 3, make the large granular materials of fragment of brick, cement block, iron wire and so on can under the purging of water cooled wind chamber 1, slide in the mouth of pipe of scum pipe 6 of lower along the V-arrangement inclined plane on pouring layer 5 surface and waveform face, on the pouring layer 5 that large granular materials is not easily accumulated in below blast cap 3 aperture, avoid the pouring layer 5 i.e. generation of the higher even coking situation of fluid bed bed surface local temperature, thus ensure that the operation with security and stability of fluidized-bed combustion boiler.
