A hole forming member 32 is provided. A schematic perspective view of the elongated hole forming member 32 is shown in FIG. This cross section is as shown in FIG.

  The elongated hole forming member 32 is provided in the combustion section 3 and is used for further burning smoke generated by combustion of combustion substances. Specifically, the elongated hole forming member 32 includes a side wall member 321, and further, a smoke guide plate 322 and an inclined plate 323 are provided on the upper side portion of the side wall member 321.

  Further, the side wall member 321 of the elongated hole forming member 32 forms an elongated hole H at the top. Here, the elongate hole means a thin hole along the axial direction of the rotating shaft, but it is only necessary to form a thin and long hole as a whole, and the hole may be blocked in the middle. For example, as shown in FIG. 3, a plurality of plate members 322 that are convex upward or convex downward may be arranged.

  In the present apparatus 1, by forming the elongated hole H in this way, the flow of smoke can be narrowed to make a thin upward flow. As will be apparent from the description below, smoke can be reburned by changing this flow in various directions.

  In addition, as described above, the plate member 322 is preferably arranged in the elongated hole H portion of the elongated hole forming member 32 so as to have an upward convex or downward convex part.

  The smoke guide plate 323 is provided above the side long hole, and is a plate for guiding the rising smoke to the side or the upper side. By providing this plate, it is possible to generate agitated smoke that spreads in the side or diagonally upward direction, rather than a simple upward flow. That is, the smoke guide plate 323 preferably extends obliquely upward from the side long hole side.

  The inclined plate 324 is provided below the side long hole, and is used to return the fine powder generated in the smoke back into the long hole forming member 32 again. As a result, it is possible to prevent the fine powder in the smoke from accumulating in the apparatus. In addition, it is preferable that the edge part of this inclination board 324 bends upwards.

In the present apparatus 1, the combustion material efficiently burned inside the outer wall member 32 is returned again into the outer wall member 32 by the roof member, and the final combustion is performed. Therefore, in this apparatus 1, it is preferable that the roof member 33 has a convex ceiling.

  Here, the flow of smoke generated by the combustion by this apparatus will be described.

  First, the combustion substance combusted in the combustion substance conveying part in the combustion part is carbonized while generating smoke. On the other hand, the smoke rises and is introduced into the elongated hole forming member 32. And by being discharged by the elongated holes and the side elongated holes in the elongated hole forming member 32, the flow is once adjusted and then diffused in the respective directions. In this case, since the inner roof member 325 is provided in the elongated hole forming member 32, the smoke is sufficiently stirred even in the previous stage.

  The smoke discharged from the elongated hole hits the roof member for the elongated hole and is stirred again, and the smoke discharged from the side elongated hole is further guided in the lateral direction by the smoke guide plate and rises again while being stirred.

  The smoke rising from the outer wall member 32 is returned again into the outer wall member by the outer wall member roof member 33. That is, the smoke is agitated many times in the outer wall member, and it is burned and recovered by the heat inside the outer wall member, so that the risk of smoke being discharged out of the device is remarkably reduced, and an extremely transparent air flow is generated. It is discharged from the gap G.

  As mentioned above, the carbonization apparatus which can suppress generation | occurrence | production of smoke can be provided by this invention.

This apparatus has industrial applicability as a carbonization apparatus.
