The operation will be described below. The incinerated matter is, for example, sludge-like residue when a fish body is processed in marine products processing, and a case of incinerating this residue will be described. The residue (hereinafter referred to as "incineration product") generated when the fish body is treated has an extremely large amount of water, and further contains a large amount of fats and oils and odorous components. Therefore, as shown in FIGS. 1 and 2, the incinerator 50 is dehydrated by the dehydrator 17. The incinerator 50 is precipitated by the dehydrator 17 with a coagulant, and then the cake-like water content is dehydrated to about 80% by a filter cloth traveling type solid-liquid separator. Then, the dehydrated incinerated matter is conveyed by the belt conveyor 18 and is supplied to the supply port 2c provided at the base end of the drying conveyor 2 of the drying and incinerating apparatus 1.

On the other hand, the drying and incineration apparatus 1 is in a standby state for drying and incinerating the incineration material supplied. That is, the drying burner 5 is ignited, and the drying conveyor 2, that is, the transport mechanism 21 (FIG. 3) housed in the trough 20 is heated to a high temperature. Then, the transport mechanism 21 is in a state in which the incinerator 50 that is rotationally driven by the drive mechanism 4 and is supplied is dried and can be transported to the combustion furnace 3. At the same time, the dehumidifying blower 12 is driven and the upper portion 20 of the trough 20 is driven.
The gas filled in b can be sent to the base end 22a side in the cylindrical body 22 of the transfer mechanism 21.

Furthermore, the incinerator blower 6 of the combustion furnace 3 is driven, the combustion air is supplied into the lower combustion chamber 35, and the incinerator conveyed into the combustion furnace 3 by the conveying mechanism 21 can be combusted. . The reburn burner 7 is also ignited to enable combustion of the combustion components rising from the lower combustion chamber 35 to the upper combustion chamber 36 through the passage 37. Furthermore, exhaust blower 1
0 is driven so that the exhaust gas in the upper combustion chamber 36 can be discharged to the cyclone 9.

Now, the incineration material 50 supplied to the supply port 2c of the drying conveyor 2 drops to the base end 22a of the cylindrical body 22 of the transfer mechanism 21 as shown in FIG. The transport mechanism 21
The incinerator 50 is heated to a high temperature by the dry burner 5, and is conveyed to the combustion furnace 3 as indicated by an arrow A while being dried by indirect heating. The incinerator 50 is gradually dried and dry-distilled by evaporation of moisture, fats and oils and odorous components when being conveyed while being heated to a high temperature. As a result, a large amount of water vapor, fats and oils, and odorous components are generated from the incinerated material 50. And, these water vapor, oil and fat and odorous components are stored in the trough 2
Fill the upper part 20b of 0. Then, the amount of evaporation is remarkable especially on the base end 20e side of the trough 20.

Moisture (water vapor) filled in the trough 20,
The mixed gas composed of oil and fat and odorous components is supplied from the upper portion 20b on the base end side of the trough 20 to the base end 22a side in the cylindrical body 22 of the transport mechanism 21 by the dehumidifying blower 12, and the cylindrical bodies 22, 27 and the cylinder It is delivered to an annular space 29 between it and the body 28. Then, the mixed gas is heated while being spread in the annular space 29 and is fed to the front side of the flame of the dry burner 5. The inside of the cylindrical body 22 is in an extremely high temperature state due to the flame of the dry burner 5.
Due to the flame, the water content of the mixed gas becomes extremely high-temperature steam, the oil and fat components are almost completely burned, and the odorous components are almost completely thermally decomposed. Then, these gases become a flame and blow out from the tip of the cylindrical body 22 into the combustion furnace 3 (arrow B).

The mixed gas composed of a large amount of water vapor, oil and fat components, odorous components, etc. generated in the trough 20 is fed into the cylindrical body 22 by the dehumidifying blower 12 from the base end side of the trough 20 as described above. Since it is removed by being removed, the inside of the trough 20 becomes extremely low in humidity, and is kept in a high temperature and dry state. As a result, the incineration product 50 is extremely efficiently dried, and the moisture, oil and fat components, and odorous components are satisfactorily removed. When the incinerated material 50 is dried and conveyed, it is scraped off by a scraping plate 20j that is suspended at an appropriate position on the top plate 20d of the trough 20 shown in FIG. As a result, the incinerated material 50 is agitated and dried more favorably.

The scraping plate 20j may be provided at one place, or a plurality of scraping plates 20j may be provided at appropriate intervals along the longitudinal direction of the trough 20. Further, the scraping plate 20j is not always necessary. That is, when the incinerated material 50 is difficult to adhere to the cylindrical body 22 and the transport coil 23 of the transport mechanism 21, it is not necessary to scrape it off, and thus the scraping plate 20j is not necessary.

Then, as shown in FIG. 6, when the incinerated material 50 is transported from the tip 22b of the cylindrical body 22 of the transport mechanism 21 to the moving coil 24, moisture, oil and fat and odorous components are almost completely removed and dried. It is in the state of being The dried incineration material 50 is carried into the lower combustion chamber 35 of the combustion furnace 3 by the moving coil 24, the air supplied from the incineration blower 6 on the combustion table 25, and the cylindrical body 2 of the transfer mechanism 21.
By the flame blown out from the tip 22b of No. 2, it is almost completely burned and incinerated.

The remaining combustion components generated from the incineration material 50 combusted in the lower combustion chamber 35 are sent to the upper combustion chamber 36 through the communication passage 37 together with the high temperature steam and gas discharged from the cylindrical body 22. The reburning burner 7 reburns the rest of the combustion components sent to the upper combustion chamber 36. And
The exhaust gas after being completely combusted in the upper combustion chamber 36 is taken into the cyclone 9 by the exhaust blower 10 shown in FIG. 1, the gas content is discharged from the chimney 11 together with the high temperature steam, and the ash content is the ash box. 45 (FIG. 1). As a result, the gas discharged from the chimney 11 hardly contains dust and odorous components.

On the other hand, the ash content of the incineration material burned in the lower combustion chamber 35 is stored in the ash box 46 (FIG. 1) through the discharge hole 3e from the tip of the combustion table 25 as the moving coil 24 rotates. In this way, the sludge-like incinerator 50 in which a large amount of water, fats and oils and odorous components are mixed is dried and completely incinerated without discharging a bad odor. The ash content of the incinerator 50 is easy to process because the oil and fat content and the odor are completely removed.

In the drying and incineration apparatus 1, if the dehumidifying burner 12 is stopped due to some reason during incineration, the afterburner 8 is ignited and the afterdehumidifying blower 13 is operated to generate in the trough 20. The mixture is fed to the upper combustion chamber 36 of the combustion furnace 3 and burned. That is, the after-dehumidification blower 13 is activated immediately after the dehumidification blower 12 is stopped, and the mixed gas of water vapor, oil and fat and odorous components generated in the trough 20 is transferred to the trough 20 as shown in FIG.
Is taken in from the front end side, is fed to the communication passage 37 of the combustion furnace 3 through the pipes 42 and 43, and is fed into the upper combustion chamber 36. The afterburner 8 burns the oil / fat component fed into the upper combustion chamber 36 and thermally decomposes the odorous component.
As a result, the oil and fat components and odorous components of the air-fuel mixture generated in the trough 20 are completely incinerated. At this time, the after-dehumidification blower 13 operates as an auxiliary blower, and the after burner 8 operates as an auxiliary burner.

In addition, the drying and incinerating device 1 includes an incinerator 50.
After completion of incineration, the drying conveyor 2, the drying burner 5,
The dehumidifying blower 12, the incineration blower 6, and the reburning burner 7 are stopped. However, even after the incineration is completed, a slight amount of the mixed gas of water vapor, fats and oils and odorous components remains in the trough 20. Therefore, the afterburner 8 and the after-dehumidification blower 13 are operated to completely incinerate these residual components, particularly the oil and fat components and the odorous components. Then, after the incineration process of the oil and fat components and the odorous components remaining in the trough 20 is completed, the afterburner 8 and the after-dehumidification blower 13 are stopped, and the incineration process of the incineration material 50 is completed.

The pipe 4 to which the dehumidifying blower 12 is connected
The position of the suction port (hole 20h) on the trough 20 side of No. 0 is not particularly limited, but in the present embodiment, as shown in FIG. 5, it is slightly on the tip side of the incineration material supply port 2c of the trough 20. By positioning, it is possible to immediately remove large amounts of water vapor, fats and oils, and odorous components that are generated near the base end of the drying conveyor 2, that is, near the supply port 2c, and supply the water to the cylindrical body 22. There is an advantage that the inside of the trough 20 can be maintained at a low humidity and the incineration material 50 can be dried more favorably. However, the suction port of the pipe 40 may be at the rear end of the trough 20 or at the intermediate position,
Further, it may be provided on the upper surface of the trough 20, that is, on the top plate 20d.

Further, in the present embodiment, the transport mechanism 21 of the drying conveyor 2 has a configuration in which the transport coil 23 is continuously provided in a spiral shape on the cylindrical body 22 from the base end to the tip, but it is not limited to this. Instead, it may have a structure in which a large number of feed blades are intermittently arranged in a spiral shape. Further, the moving coil 24 which is spirally continuous is provided at the tip of the cylindrical body 22 and is moved in the combustion furnace 3 while stirring the incinerated matter conveyed from the conveying coil 23, but the present invention is not limited to this. Instead, another structure, for example, a central axis is arranged at the center position of the tip of the cylindrical body 22 along the longitudinal direction of the cylindrical body, and the base end thereof is provided at the distal end of the cylindrical body 22 via a support rod radially provided. A large number of support rods of predetermined length are provided in a radial direction at appropriate intervals along the longitudinal direction of the central axis, and spiral blades are provided at the tip of each support rod to send the incinerated matter while stirring. Such a structure may be used.

Furthermore, in the present embodiment, the case where the gun type oil burner is used as the reburn burner 7 has been described, but the present invention is not limited to this, and other types of burners may be used. In addition, in the above-mentioned example, a large amount of water, such as the residue of fish bodies in seafood processing as incineration, a large amount of water, fats and oils, a case of incinerating a sludge-like substance mixed with an odor component, etc. was described. The material to be dried or incinerated, which is not limited, and which produces a bad odor particularly when dried or incinerated, for example,
Needless to say, it can be applied to incineration of livestock wastes from poultry farms and pig farms, and wastes when processing prepared foods.
