Abstract
The invention relates to an air distribution plate for a sludge incinerator, in particular to an air distribution plate arranged in a hearth of a fluidized bed boiler used for sludge incineration. The air distribution plate comprises a water cooling air chamber, wherein a steel plate is arranged on the top of the water cooling air chamber, pipe holes are uniformly distributed in the steel plate, air distribution short pipes are uniformly distributed in the pipe holes, the upper ends of the air distribution short pipes respectively extend to a position above the steel plate, the upper end of each air distribution short pipe is provided with an air cap, and multilayer small holes are uniformly distributed in the periphery of each air cap. A casing layer used as the bed surface of a fluidized bed is arranged on the steel plate arranged under the air cap. The air distribution plate is characterized in that the upper surface of the casting layer is an approximately V-shaped surface from being seen from the left side or the right side of a boiler, so that an included angle is formed between the upper surface of the casting layer and the horizontal plane. The air distribution plate is adopted, the safe and stable operation of the boiler can be ensured.
Description
Technical field
The present invention 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.
Summary of the invention
The problem to be solved in the present invention 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 that the present invention will solve are realized by following technical scheme:
Sludge incinerator air distribution plate of the present invention 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 approximate 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 approximate 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 approximate 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.
Accompanying drawing explanation
Fig. 1 is sludge incinerator air distributor structure schematic diagram of the present invention;
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 invention, 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.
