[0011]

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the incinerator of the present invention will be described below with reference to the drawings. In the incinerator 1 shown in FIGS. 1 to 3, the casing 3 is made of a tubular body having a regular octagonal cross section, and the tip portion (right side of the figure) is slightly inclined to the installation surface G via the leg body 2. It is set.

The casing 3 has lids 3b and 3b fixed to both ends of a horizontally long cylindrical main body 3a.
Bearings 4 and 4 are arranged in the central portions of b and 3b.
A hollow rotary shaft 5 is installed between the four so as to rotate by the drive of a drive means (not shown). The rotation speed of the rotary shaft 5 by this driving means may be constant, but in this embodiment, it can be adjusted by the controller C.

Further, inside the base end of the cylindrical main body 3a, a drying cylinder 7 surrounds the hollow rotary shaft 5 and is held at a hollow position by opening the front end. Below the base end of the drying cylinder 7, a conveyor 8 is fixed to the casing 3 to put incineration materials such as dust.
Are pierced through the cylindrical main body 3a and connected. Conveyor 8
In the illustrated example, the screw conveyor 8
b is built-in, the outlet port 8c on the tip (inner end) side extends linearly, and the inlet port 8d on the base end (outer end) side is curved so as to face sideways.

As shown in FIG. 3, the conveyor 8 is arranged obliquely with respect to the center line of the casing 3, and by adjusting the mounting position with respect to the casing 3 in the longitudinal direction, the tip position of the conveyor 8 is set to the drying cylinder 7. Since it can be adjusted in the front-back direction, it can be changed to the optimum position depending on the type and size of the incineration object. Further, since the conveyor 8 can adjust the conveying speed, the conveying amount can be adjusted according to the incineration condition. Since the conveyor 8 is used as the charging method as described above, the conveying speed of the conveyor 8 can be controlled, an excessive temperature rise of the incinerator can be prevented, and the conveyor 8 can be adjusted according to the type and size of the conveyed object. It is possible to achieve efficient combustion by adjusting to a different charging position.

Next, inside the drying cylinder 7, the hollow rotating shaft 5 is provided with a stirring blade 9 as an example of stirring means via a support 10 extending radially. The stirring blade 9 includes a screw blade (ribbon screw).
You may wind around and carry a to-be-conveyed object.

Inside the tip of the casing 3, a combustion cylinder 11 is provided.
Are fixed to the hollow rotary shaft 5 via a support 12 so as to surround the hollow rotary shaft 5. The combustion cylinder 11 is composed of a drum screen in which a base end portion 11a made of a metal cylinder body and a grate 11b formed in a cylinder shape and having a diameter substantially the same as that of the base end portion 11a are connected in series. The base end portion 11a is externally fitted to the tip end portion of the drying cylinder 7 and is disposed with a rotatable interval,
It is a relay part for transferring the burned material transferred from the drying cylinder 7 to the grate 11b.

Next, the grate 11b is formed by arranging a plurality of linear rods extending in the front-rear direction at equal intervals in the circumferential direction, and using a long round rod around them to spirally incline toward the discharge side. It is wound into a tubular shape and is formed into a tubular shape so that predetermined eye holes are formed in the front and rear. As a result, a force acts on the burned material in the grate 11b in the direction of rotation due to the rotation of the grate 11b, but the peripheral wall of the grate 11b is formed by a spirally wound round bar, and thus is discharged. Guided in the direction.

The transfer of the burned material is not limited to the above configuration,
A transfer blade or other transfer means for transferring the burned material may be provided in the grate 11b. On the outer wall surface of the grate 11b, a transfer means 13 composed of a ribbon screw for transferring the ash dropped from the eye holes of the grate 11b to the front side (discharging side) is spirally mounted.

At the bottom of the casing 3, the grate 11b
From the middle position to the position corresponding to the tip, the ash discharge port 14
Is formed, and a discharge port 15 for the incinerated matter discharged from the tip of the grate 11b is formed at a position corresponding to the tip of the grate 11b. In the illustrated example, one discharge port is used by being divided into two at the front and rear, but separate discharge ports may be provided. In the figure, reference numeral 16 is a flame lid, and a smoke collecting chamber 17 is formed in the casing 3. The smoke collected in the smoke collecting chamber 17 is provided at the top of the casing 3 near the tip of the grate 11b. A smoke outlet 18 for discharging is formed.

Next, at the tip of the casing 3, a mouth of a burner 19 for radiating flames is arranged below the smoke collecting chamber 17. Similarly, at the base end of the casing 3, a burner 19 for radiating flame to the base end of the drying cylinder 7 is also provided.
A mouth portion (not shown) is provided. Thereby, each of the burners 19 can heat the drying cylinder 7 and the combustion cylinder 11, respectively. The heating amount of the burner 19 may be the same, but in the present embodiment, the heating amount can be changed by the controller C for heating.

Next, the hollow rotary shaft 5 is formed with a plurality of fumaroles 5a on its peripheral wall at substantially equal intervals along the longitudinal direction, and is connected to a blower device (not shown). In the case of the illustrated example, the fumaroles 5a are inclined and are provided in a large number at substantially equal intervals in the longitudinal direction of the rotating shaft, but they are provided in pairs in the diametrical direction on the peripheral wall of the rotating shaft, and are adjacent to each other. The fumaroles 5a are arranged at 90 ° intervals along the circumferential direction. Further, the fumaroles 5a, 5a provided facing each other in the front-rear direction are arranged so that the fumes are directed in the opposite directions. This arrangement is not limited to the above-mentioned embodiment. In short, the drying cylinder 7 and the combustion cylinder 11 are provided by providing the fumarole holes at substantially equal intervals in the circumferential direction of the rotary shaft and by providing the fumes in the forward and reverse directions. Air (oxygen) may be supplied uniformly.

Therefore, the front and rear fumaroles 5a and 5a are set so that the front and rear fumes cross each other. In the figure, reference numerals 20 and 20 are connectors for connecting an air supply hose of an air supply means (not shown) for supplying air to the hollow rotary shaft 5 from the outside. The amount of air supplied may be constant, but
In this embodiment, the controller C can appropriately adjust. It is preferable to dispose a flue gas treatment device (such as a cyclone) at the flue gas outlet 18 through a flue gas duct (not shown).

The operation of this embodiment having the above construction will be described. First, by operating the burner 19, the smoke collection chamber 1
7 can be heated to a moderate temperature. Then, when the burned material is carried into the drying cylinder 7 fixed in the casing 3 from the loading conveyor 8, the stirring blade 9 that rotates in conjunction with the rotation of the hollow rotary shaft 5 functions as a scraping blade. Then, the burned material in the drying cylinder 7 is agitated, and the burner 1 at the base end portion is stirred.
The articles to be burned are extruded forward by the articles to be conveyed which are heated by 9 and successively conveyed by the conveyor 8, so that the articles to be combusted are primarily burned and dried, and are extruded from the drying tube 7 to the combustion tube 11 side. At this time, particularly when the transported object is a viscous material such as fresh cream, the transportation speed of the conveyor 8 can be adjusted to prevent an excessive temperature rise in the incinerator.
Alternatively, depending on the type and size of the transported object, the conveyor 8
The tip position of the can be adjusted back and forth to achieve efficient combustion. If blades such as a ribbon screw are used, it becomes easier to transfer the material to be incinerated.

The dried burned material is pushed out of the drying cylinder 7 and moves to the base end side of the combustion cylinder 11. Since the combustion cylinder 11 rotates in conjunction with the hollow rotary shaft 5, the burned material that has entered the combustion cylinder 11 burns while rolling in the combustion cylinder 11 and is granulated while being granulated. The ash smaller than the holes falls on the inner bottom wall of the casing 3. This ash is conveyed to the ash discharge port 14 by the conveyor 13 and discharged.

Since the grate 11b is made of a stainless steel lead material whose peripheral wall is spirally wound toward the discharge side, if the burned material which has become small particles is still larger than the eye hole, Guided by this, the grate 11b is gradually transferred to the discharge side by the rotation of the grate 11b. Then, those that do not fall through the eye holes of the grate 11b fall through the tip opening of the grate 11b and are discharged from the discharge port 15. As a result, the ash and the other can be separated and discharged.

In this case, the hollow rotating shaft 5 has the fumarole 5a.
Since it is opened, oxygen can be evenly and sufficiently supplied to the rolling combustible material even in a slender incinerator, and the fumes ejected from the fumaroles 5a are before and after the furnace. Since the hot air can be agitated by intersecting the directions, the combustion effect is remarkably improved.

A burner may also be arranged at the base end of the drying cylinder 7, and the hot air in the drying cylinder 7 enhances the granulation and the drying effect in the drying cylinder 7, and the base end of the furnace. And tip burners 19
Since the hot air of 2 intersects in the central part of the furnace, the heating effect is improved. The set temperatures in the drying cylinder 7 and the combustion cylinder 11 are around 650 ° C. to 700 ° C. in the case of this embodiment, but the combustion temperature of both burners 19 and the air supply means such as a blower device at both ends of the rotary shaft 5 are fed. It can be changed by controlling the air volume and controlling smoke emission such as adjusting the opening area of the smoke exhaust port as necessary.

A lower heating temperature is suitable for drying the material to be burned. When the heating temperature is high, it is completely combusted, and when it is at an intermediate temperature, it can be carbonized. Further, when the water content of the material to be burned is high, it is necessary to lower the rotation speed of the combustion cylinder 11 (rotation speed of the rotary shaft 5), and the water content of the material to be burned can be adjusted each time. Optimum values of these temperatures are experimentally determined depending on the type of burned material and the input amount, and are stored as data for the controller C.

For that purpose, driving means such as a rotary motor of the rotary shaft 5, air feeding means such as a blower device, and a burner 19
Can be automatically controlled by the controller C. The transfer speed of the loading conveyor 8 can also be automatically controlled by the controller C.
That is, as shown in FIG. 8 and FIG. 9, the type of burned material (type sorted by material, moisture content, etc.) and input amount, and degree of combustion (“dry”, “carbonized”, “incinerated”) And the like) are input to the controller C via input means such as buttons. In the controller C, in the arithmetic processing unit, based on the input conditions, the conveying speed of the conveyor 8, the heating temperature by the burner, and the air supply amount by the blower corresponding thereto,
The time for which the transported object is heated (residence time in the furnace) is determined. In this case, as shown in FIG. 10, since the relationship between the heating temperature and the residence time in the furnace has a constant relationship for each type of burned material, the control value is determined based on this data. Based on this determination, the heating temperature of the burner is controlled via an actuator (not shown) to heat the inside of the furnace at a predetermined temperature, the amount of air supplied is controlled, and the air is supplied from the fumaroles. The rotary motor of the rotary shaft is controlled so as to correspond to the internal residence time, and the rotary shaft rotates at a predetermined speed to determine the moving speed of the burned material in the furnace.

Further, the operation processing unit may determine the operation pattern based on the input condition, and the combustion in the drying cylinder and the combustion in the combustion cylinder may be separately controlled based on the operation pattern. Good. For example, in the combustion pattern for incineration of cuttings, the burner 19 on one side (for example, the drying cylinder 7) is used to set the heating temperature lower than the ignition temperature of the burned object and heat it for a predetermined time to dry it. And then
Next, incineration is performed by using both burners 19 to set the maximum temperature considerably higher than the ignition temperature and heating for a predetermined time. In addition, in the carbonization pattern for incineration of cuttings, both burners 19 are heated to the maximum temperature for a predetermined period of time, and the air supply amount is set to be equal to or more than the required theoretical air amount, and then the ignition temperature of the burned material is set. The temperature is lowered to a temperature slightly higher than that of the theoretical air amount by 50%, and heating is performed for a predetermined time. Then, after heating is completed and the inside of the furnace is at room temperature, it is discharged to obtain a carbide. Further, as will be described later, if the combustion cylinder is tilted using the lifting device so that the tip end faces upward, the residence time in the combustion cylinder can be adjusted regardless of the speed of the rotating shaft. In this way, by controlling the heating temperature and the heating time, it is possible to perform optimum combustion according to the property and the degree of combustion of the burned material.

As a specific example, when treating 1.5 m ³ of cuttings (water content 59%) such as street trees, the furnace temperature is 650.
° C, combustion cylinder rotation speed 10 rpm, throughput 1.25 m ³ /
Emission amount is 0.2 when H is 72 minutes
m ³ , the volume reduction rate was 13.3%, the inner diameter of 2 mm or more was 0.08 m ³ , 2 mm or less was 0.1 m ³ , and cyclone collection was 0.02 m ³ , and a good incineration effect was obtained. The results of processing by changing the specifications in this processing are as follows.

Since the ignition temperature of the cuttings is about 142 ° C., the burner 19 on the drying cylinder 7 side is used to set the furnace temperature to 1
The water content of the cuttings was set to 13% by setting the temperature to 20 ° C., the rotation speed of the rotary shaft 5 of 5 rpm, and the processing time of 20 minutes. After that, both burners 19 were used to set the furnace temperature to 650 ° C., and the number of revolutions of the combustion cylinder 11 was set to 10 rpm for incineration. As a result, the processing time could be shortened by 11 minutes as compared with the above case.

In order to treat the cuttings, the front and rear burners 19 are used, the furnace temperature is set to 650 ° C., the rotation speed of the combustion cylinder 11 is set to 5 rpm, and the combustion components are required for combustion. Supply more than the theoretical air amount, and after 20 minutes, lower the furnace temperature to 180 ° C and change the air supply amount to 50% of the theoretical air amount.
%, The cyclone capacity was set to 50%, and the operation was stopped after 80 minutes had elapsed. Combustion cylinder 11 as the furnace temperature rises
Was rotated at high speed to discharge the contents. The amount of discharge is about 0.85 m ³ , of which 0.0
At 5 m ³ , the remaining unburned material was obtained as granular porous carbide with a particle size of 6 mm or less.

As described above, in this embodiment, the combustion degree of the incineration object is controlled by controlling the input amount of the combustion object, the temperature in the furnace, the air supply amount, the exhaust amount, and the rotation speed of the rotary shaft. It was recognized that it could be changed arbitrarily. In particular, by providing a burner also at the base end of the furnace and supplying air from the rotary shaft, efficient combustion can be performed in the drying cylinder. Further, the obtained carbide can be utilized as a resource, and the gravel-like non-incinerated matter obtained by incinerating sludge can be reused for landfilling.

In this embodiment constructed as described above, the apparatus can be downsized and the primary combustion (drying) step can be omitted to perform the combustion step.
In addition, the combustion cylinder 11 that rotates in conjunction with the hollow rotary shaft 5 is slowed down to dry the material to be burned in a state where the furnace temperature is low, and then heated to a high temperature for combustion or carbonization. In addition, it can be operated depending on the application. In this case, the front part of the casing 3 can be raised by the operation of the elevating device 21 in order to prevent the combustion object from advancing during drying.

The incinerator 1 is substantially the same as the first embodiment except that the discharge ports 14 and 15 are provided separately, and therefore, the same reference numerals are given to the same configurations and the description thereof will be omitted. The casing 3 of the incinerator 1 is loaded and fixed on a truck 23 via a pedestal 22. A first pipe conveyor 24, which continuously transfers the burned material, extends from the left outside of the vehicle and is detachably connected to the input port of the conveyor 8. That is, the discharge port 24a is formed on the inner end side of the first pipe conveyor 24 and is disposed right above the input port, and the input port 24b is formed on the outer end side disposed on the installation surface. It is possible to add a burnt material.

A movable screw conveyor 25 is disposed on the loading platform below the ash discharge port 14 so as to extend forward and backward toward the tip side, and at the lower part of the discharge port 25a, extends to the right outside of the vehicle.

The third pipe conveyor 27 is connected to the second pipe.
Along with the pipe conveyor 26, it extends in parallel and the outer end side rises obliquely to form a discharge port 27a. This allows
The second pipe conveyor 26 and the third pipe conveyor 27 can be sorted into two storage boxes 28a and 28b to transport ash and non-incinerated matter or dried matter. Reference numerals 24c, 26c,
