Providing uniform primary air for the garbage bed layer.
As shown in fig. 1, in the embodiment of the present invention, an ash bucket 100 of a garbage incinerator with uniform air distribution is provided, and the ash bucket 100 is located below a fire grate of the garbage incinerator. The ash hopper 100 is located below the grate of the garbage incinerator for discharging ash and providing a flow path for the primary air, and the ash hopper 100 includes a hopper main body including a cone section (cone-like section) 110 and a column section (column-like section) 120 located above the cone section 110, and in one example, the cone section 110 is rectangular and the column section 120 is rectangular as viewed in the direction of a-a. Of course, one skilled in the art will appreciate that the cone segments 110 may also be inverted trapezoidal when viewed from the left-hand direction. The cone segment 110 comprises a first opening 111 located above, a second opening 112 located below, and a sidewall connecting the lower first opening 111 and the second opening 112, the area of the first opening 111 being larger than the area of the second opening 112.

In one example, the second flow directing structure 150 comprises a second flow directing plate having a V-shaped cross-section perpendicular to its direction of extension, i.e., the second flow directing plate comprises two plates joined to one another and integral. In one example, the opening direction of the V-shape is away from the bottom surface of the cone segment 110, i.e. the opening direction of the V-shape is towards the second opening 112. In one example, the first guide plate is arranged below the V-shaped opening of the second guide plate, in one example, the first guide plate is arranged below one guide plate of the second guide plate, namely, in the vertical direction (up-down direction), the central axis (or the vertex of the V-shaped opening) of the V-shaped opening is staggered with the top of the vertically arranged first guide plate by a preset distance, so that primary air can pass through the second guide plate completely, and the effect of uniform air distribution of the second guide plate can be realized.
In one example, the second baffle is provided with holes 151. In one example, as shown in fig. 2, the holes 151 comprise circular holes. The setting up of the circular port on the second guide plate more is favorable to once wind by homodisperse. Those skilled in the art will appreciate that the arrangement of the holes 151 in the second baffle may be various, and will not be described herein. In one example, the holes 151 in the two plates of the second baffle are arranged in the same or different patterns.

In one example, the angle of the opening of the V-shape of the second baffle is between 10 degrees and 45 degrees. Those skilled in the art will appreciate that the angle of the opening of the V-shape of the second deflector can be varied as long as the angle of the opening of the V-shape of the second deflector is less than the angle of repose of the ash, thereby avoiding the deposition of ash on the top surface of the second deflector.
In one example, the plane of the end surface of the portion of the air inlet pipe 130 in the cone segment 110 is at an angle with respect to a plane perpendicular to the axis of the air inlet pipe 130, that is, the end surface of the portion of the air inlet pipe 130 in the cone segment 110 extends obliquely upward from a side near the second opening 112 of the cone segment 110 to a side near the first opening 111 of the cone segment 110. This arrangement prevents falling ash from entering the inlet pipe 130.
In one example, the first and second flow guiding structures 140 and 150 are connected to the inner sidewall of the cone segment 110 by welding.
The flow process of the primary air of the application is as follows: the primary air is firstly divided into a plurality of fluid flows upwards after being shunted by the primary air deflector, and the plurality of fluid flows upwards vertically after passing through the secondary air deflector and is uniformly dispersed into more strands of fine fluid by the round holes on the secondary air deflector, thereby realizing the uniform air distribution effect of the primary air.
