Abstract
The utility model discloses a kind of CFB garbage burning boiler air distribution plate, comprise air distribution plate body; Described air distribution plate body is provided with some blast caps, and centre has cinder notch; Described fall the blast cap at cinder notch edge be 7 shapes guiding blast caps, all the other are mushroom-shaped blast cap; The wind direction of described guiding blast cap is along the tangential direction of the circle being the center of circle with the cinder notch central point that falls.Have the air distribution plate of said structure, the heavy caliber be evenly arranged by slag-drip opening surrounding large kinetic energy guiding blast cap, its wind direction circle of contact is arranged, provides enough large slag-drip opening blind area fluidisation power and deslagging guiding force, and fluidisation and the deslagging of guarantee cloth wind blind area are unobstructed; All the other wind distributing faces adopt small-bore mushroom blast cap, and mushroom-shaped blast cap has can flexible arrangement, ensure the uniform advantage of fluidisation, are particularly suitable for using on the air distribution plate of this kind of small-sized fluidized bed band of garbage burning boiler water cooled wind chamber.
Description
Technical field
The utility model relates to a kind of CFB garbage burning boiler air distribution plate.
Background technology
Rubbish is as a kind of extremely uneven simple and mechanical mixture, and in various CFB waste incineration engineering, due to physical condition difference, garbage fuel is before entering incinerator, and various processing mode is different.Enter the fuel granularity size in CFB Boiler Furnace, non-combustible material block group size differences is very large.Rubbish is as the physical mixture of various material, and moisture is higher, the non-constant of mobility, and its deslagging requires higher than conventional fuel.
What existing air distribution plate adopted is all that mushroom-shaped blast cap carries out cloth wind, and its cinder notch that falls is for circular.And the thing block of bulk fluidisation wretched insufficiency in stove, often have influence on the normal operation of CFB boiler, the situation that the deslagging that happens occasionally is not smooth.
Utility model content
For the technical problem of above-mentioned existence, the utility model provides a kind of CFB garbage burning boiler air distribution plate, provides enough large slag-drip opening blind area fluidisation power and deslagging guiding force, and fluidisation and the deslagging of guarantee cloth wind blind area are unobstructed.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of CFB garbage burning boiler air distribution plate, comprises air distribution plate body; Described air distribution plate body is provided with some blast caps, and centre has cinder notch; Described fall the blast cap at cinder notch edge be 7 shapes guiding blast caps, all the other are mushroom-shaped blast cap; The wind direction of described guiding blast cap is along the tangential direction of the circle being the center of circle with the cinder notch central point that falls.
As one preferably, the cinder notch that falls described in is rectangle.Meet the characteristics of motion of boiler material in stove of combustion refuse.
Usefulness of the present utility model is: the air distribution plate with said structure, the heavy caliber be evenly arranged by slag-drip opening surrounding large kinetic energy guiding blast cap, its wind direction circle of contact is arranged, there is provided enough large slag-drip opening blind area fluidisation power and deslagging guiding force, fluidisation and the deslagging of guarantee cloth wind blind area are unobstructed; All the other wind distributing faces adopt small-bore mushroom blast cap, and mushroom-shaped blast cap has can flexible arrangement, ensure the uniform advantage of fluidisation, are particularly suitable for using on the air distribution plate of this kind of small-sized fluidized bed band of garbage burning boiler water cooled wind chamber.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of guiding blast cap.
Fig. 3 is the structural representation of mushroom-shaped blast cap.
Mark in figure: 1 air distribution plate body, 2 fall cinder notch, 3 guiding blast cap, 4 mushroom-shaped blast caps.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 2, its wind direction fixed point is toward a direction for guiding blast cap described in the utility model.And mushroom-shaped blast cap as shown in Figure 3, its wind direction to all the winds, is uniformly distributed along the circumference.
As shown in Figure 3, the utility model comprises air distribution plate body 1; Described air distribution plate body 1 is provided with some blast caps, and centre has cinder notch 2; Described fall cinder notch 2 be rectangle.Described fall the blast cap at cinder notch 2 edge be 7 shapes guiding blast caps 3, all the other are mushroom-shaped blast cap 4; The wind direction of described guiding blast cap 3 is along the tangential direction of the circle being the center of circle with cinder notch 2 central point that falls.
When work, mushroom-shaped blast cap 4 is to four sides even distributing wind; And the wind direction of the blast cap 3 that leads is arranged along the tangential direction of the circle being the center of circle with cinder notch 2 central point that falls, make the wind of guiding blast cap 3 cloth slag can not only be blown into cinder notch 2, formed and slag tap continuously.And can fall in cinder notch 2 to being formed centrally eddy flow, strengthen fluid effect in stove.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
Claims (2)
1. a CFB garbage burning boiler air distribution plate, comprises air distribution plate body; Described air distribution plate body is provided with some blast caps, and centre has cinder notch; It is characterized in that: described in the fall blast cap at cinder notch edge be 7 shapes guiding blast caps, all the other are mushroom-shaped blast cap; The wind direction of described guiding blast cap is the tangential direction of circle that cinder notch central point is the center of circle of falling.
2. a kind of CFB garbage burning boiler air distribution plate according to claim 1, is characterized in that: described in the cinder notch that falls be rectangle.
