It is related with the heat processing apparatus which can obtain a carbide | carbonized_material.

Conventionally, as this type of heat treatment apparatus, for example, as shown in FIG. 7, a heat treatment apparatus that obtains a carbide by heat-treating an organic combustible material that is a plant waste as a treatment object is known (for example, Published in JP 2002-241760.
This is because the inner cylinder 100 to which the processing object W is supplied from the hopper 101 provided at one end, and the processing object W that is disposed inside the inner cylinder 100 and is supplied to the inner cylinder 100 is transferred to the other end side. The screw 102, a rotating outer cylinder 105 provided with a spiral convex portion 104 so that the processed material dropped from the outlet 103 on the other end side of the inner cylinder 100 through which the inner cylinder 100 is inserted, and the rotation A rotation mechanism (not shown) that rotates the outer cylinder 105 and a burner 107 that injects combustion gas into the combustion chamber 106 provided between the inner cylinder 100 and the rotation outer cylinder 105 are configured.

When the workpiece W is supplied to the hopper 101 provided at one end of the inner cylinder 100, the workpiece W is transferred to the other end side by the screw 102. At this time, since the inner cylinder 100 is heated by the combustion gas, the workpiece W is heated by the inner cylinder 100. The processed product W to be heated is removed by vaporizing the contained water. The removed moisture passes through the combustion chamber 106 from the exhaust port 108 at the upper end of the other end of the inner cylinder 10 and is exhausted from the chimney 109.

  By the way, in the above-described conventional heat treatment apparatus, the workpiece W is transferred to the other end side by the screw 102, but there are many gaps in the inner cylinder 100, so that the inner cylinder heated with the workpiece W is heated. There was a problem that contact with 100 was insufficient, heat conduction to the processed material W in the heating path was insufficient, and heating efficiency was poor. In addition, since the processed product W dropped from the inner cylinder 100 is directly heated by the combustion gas, it may be burned up and easily ashed, and the generation of carbides is difficult to be performed smoothly, and the generation yield is poor. was there.

  The present invention has been made in view of the above-mentioned problems, and can improve the heating efficiency by allowing sufficient heat conduction to the processed material in the heating path, and without directly heating with combustion gas. It is an object of the present invention to provide a heat treatment apparatus that is carbonized by dry distillation to improve the yield of carbide formation.

  In order to achieve such an object, the heat treatment apparatus of the present invention is a heat treatment apparatus for heat-treating an object to be processed, wherein a columnar body is inserted into a cylinder, and between the outer surface of the columnar body and the inner surface of the cylinder. In addition, an inlet through which the processed material is supplied is provided on one end side, and an outlet for the processed material is provided on the other end side. The processed material is sandwiched between the outer surface of the columnar body and the inner surface of the cylindrical body, and is directed from the inlet to the outlet. Forming a movable heating path, and moving means for moving the processing object supplied to the inlet of the heating path toward the outlet of the heating path, and heating the processing object moving in the heating path It is set as the structure which provided the heat provision means to provide the heat of at least any one of the said columnar body and a cylinder.

  Thereby, for example, when an organic combustible material having moisture is heat-treated and carbonized, for example, heat is applied to at least one of the columnar body and the cylindrical body by the heat applying means. In this state, the processing object is supplied to the inlet of the heating path, and the processing object is moved toward the outlet of the heating path by the moving means. During the movement of the processed material in this heating path, the processed material is heated, and the moisture in the processed material is evaporated in the initial stage of the movement and gradually dried. Things are carbonized and carbonized.

  In this case, the processed material is sandwiched and moved between the outer surface of the columnar body and the inner surface of the cylindrical body, so that the treated product is rubbed against the outer surface of the columnar body and the inner surface of the cylindrical body, that is, the outer surface of the columnar body and the inner surface of the cylindrical body. Therefore, heat conduction to the processed material is sufficiently performed, and the heating efficiency is improved. Furthermore, since the processed product is dry-distilled in the heating path, it does not burn up as compared with the case where it is directly heated with combustion gas, and is reliably carbonized. Therefore, the yield of carbide generation is improved.

Note that if the heat applying means is configured to apply heat to the columnar body, heat is transmitted from the inside to the outside, so that compared to the case where heat is applied from the outside of the cylindrical body, heat dissipation. Therefore, heat transfer is performed reliably, so that the heating efficiency is improved. In addition, the structure of the apparatus can be simplified.
On the other hand, when configured to apply heat to the cylindrical body, heat is transferred to the processed material on the columnar body side, but since heat also escapes to the outside of the cylindrical body, heat is applied to the cylindrical body Compared with, the heat transfer rate to the processed product is slightly inferior. Further, since the outside of the cylinder must be covered with a heat insulating material or the like, the apparatus becomes complicated. However, compared with the prior art, heat transfer is reliably performed, and the heating efficiency is improved.

  And, if necessary, the columnar body is formed of a tubular body, and the heat application means includes a burner device that supplies combustion gas from the front end on the outlet side of the heating path of the columnar body to the inside. Yes. Thus, heat is applied to the columnar body by the combustion gas of the burner device, and heat is transmitted from the columnar body to the processed material, so that heat is transmitted from the inside to the outside. Compared with the case where heat is applied from the outside of the body, there is no waste of heat dissipation, heat transfer is performed reliably, and thus the heating efficiency is improved. Moreover, since it can comprise by making a columnar body into a tubular body and installation of a burner apparatus is easy, the structure of an apparatus can also be simplified.

Further, if necessary, the cylindrical body is inserted into the outer cylindrical body, the outer cylindrical body is supported so as to be rotatable about an axis, and the outlet side of the heating path is interposed between the cylindrical body and the outer cylindrical body. The front end has a receiving port for receiving the processed material discharged from the outlet, the processing path has a discharge port at the rear end on the inlet side of the heating path, and the outer cylinder rotates to move the receiving port toward the discharging port. A cooling path for moving the processed material to cool the processed material is provided, and a rotation mechanism for rotating the outer cylinder is provided.
Thereby, the red hot processed material carbonized in the heating path falls from the outlet of the heating path to the receiving port of the cooling path. The outer cylinder is rotated by a rotating mechanism to cool the processed product. In this cooling process, the treated material is exposed to air, so that carbonization is promoted. The cooled processed material is sequentially discharged from the discharge port. At this time, since the processed product can be taken out after being cooled in the outer cylindrical body, it is not necessary to provide a separate cooling line, thereby saving the labor of the apparatus.

  In this case, it is effective to provide the outer cylinder with an inner surface that expands from the outlet side to the inlet side of the heating path. The outer cylinder is rotated by a rotation mechanism, and the inner surface of the outer cylinder has a tapered shape that expands from the outlet side to the inlet side of the heating path. The processed product is gradually moved toward and cooled. For this reason, the processed product can be cooled and conveyed simply by making the inner surface of the outer cylindrical body into a tapered shape, so that the structure becomes extremely simple and the apparatus can be simplified.

  Further, if necessary, the moving means supports the cylinder so as to be rotatable about an axis, and moves the processed material toward the outlet of the heating path on the inner surface of the cylinder by the rotation of the cylinder. A blade is provided, and a rotating mechanism for rotating the cylindrical body is provided. Since the processed object is sandwiched between the outer surface of the columnar body and the inner surface of the cylindrical body and moved by the blades, the processed object is surely rubbed against the outer surface of the columnar body and the inner surface of the cylindrical body, and sufficient heat conduction is performed to the processed object. Can be made.

  In this case, the moving means is provided such that the cylinder is rotatably supported around the axis, and blades are provided on the inner surface of the cylinder to move the workpiece toward the outlet of the heating path by the rotation of the cylinder. A rotating mechanism for rotating the cylindrical body, the cylindrical body and the outer cylindrical body are connected by a connecting member to be integrally rotatable, and the rotating mechanism of the cylindrical body is the rotating mechanism of the outer cylindrical body. It is effective to share it. Since the rotating mechanism of the cylindrical body is shared with the rotating mechanism of the outer cylindrical body, the apparatus is simplified accordingly and labor saving is achieved.

  Further, in this case, it is effective that the blades are constituted by screw blades that are spirally continuous, and a gap is formed between the blades and the columnar body through which the gas generated from the heated processed material can pass. It is. Since it is a screw blade | wing, a processed material can be moved continuously. Moreover, even if generated gas containing water vapor is generated from the processed material in the heating path, the generated gas can be discharged to the outside through the gap between the screw blade and the columnar body.

  Furthermore, it is set as the structure provided with the suction device which attracts | sucks the generated gas generated in the said heating path from the entrance side of this heating path as needed. Even if generated gas containing water vapor is generated from the processed material in the heating path, the generated gas can be forcibly sucked and discharged to the outside. In addition, since the generated gas is allowed to pass through the untreated material, heat exchange with the untreated material is performed, and the treated material is heated to some extent. The heating efficiency at is further improved.

  Moreover, it is set as the structure provided with the gas-liquid separation apparatus which isolate | separates a liquid from the generated gas suck | inhaled with the said suction device as needed. The generated gas can be exhausted after being cleaned.

  Furthermore, if necessary, the columnar body is formed of a tubular body, and the heat application means includes a burner device that supplies combustion gas from the front end on the outlet side of the heating path of the columnar body, The gas separated by the gas-liquid separation device is mixed with the combustion air of the burner device. Since the separated gas is mixed with the combustion air of the burner device, the heat of the gas can be used, so that the combustion efficiency is improved accordingly, and harmful components in the gas can be thermally decomposed in the combustion gas.

  If necessary, the treated product is composed of an organic combustible material, and the treated product is carbonized in the heating path to obtain a carbide. As a processed material, a fluid organic combustible material containing moisture such as livestock waste, food waste, sewage sludge, etc. can be heat-treated to obtain a carbide.

  According to the heat treatment apparatus of the present invention, in the heating path, the processed material is sandwiched and moved between the outer surface of the columnar body and the inner surface of the cylindrical body, so that it is rubbed against the outer surface of the columnar body and the inner surface of the cylindrical body. Therefore, heat conduction to the processed material can be sufficiently performed, and the heating efficiency can be greatly improved. In addition, since the treated product is dry-distilled in the heating path, it does not burn up as compared with the case where it is directly heated with combustion gas, and can be reliably carbonized, and the yield of carbide generation can be improved. As a result, it is extremely useful for fluidized organic combustible materials containing water such as livestock waste, food waste, sewage sludge, etc. Can be performed.

It will be.

  The heat applying means 60 includes a burner device 61 that supplies combustion gas from the front end on the outlet 12 side of the heating path Rh of the columnar body 1 to the inside. The burner device 61 burns oil from an oil tank (not shown) with combustion air taken in by a built-in fan and blows it into the heating path Rh. As the oil, kerosene or waste oil is used.

Therefore, for example, the case where livestock manure is processed as the processed product W by the heat treatment apparatus according to this embodiment is as follows.
First, the burner device 61 is driven. Combustion gas is supplied from the burner device 61 into the columnar body 1, and the columnar body 1 is heated. The exhaust gas is exhausted from the chimney 62.
Then, the lid 18 is opened and closed in the hopper 13, and the workpiece W is loaded when the lid 18 is opened, and the rotating mechanism 40 and the suction device 70 are driven. Loading into the hopper 13 is performed intermittently by opening and closing the lid 18 at appropriate times. In addition, you may make it throw in continuously with a pump.

  As a result, the outer cylinder 20 and the inner cylinder 10 rotate, and the scraping portion 52 of the screw blade 51 provided on the inner cylinder 10 supplies the processed material W in the hopper 13 from the inlet 11 of the heating path Rh to the inside. Furthermore, the workpiece W is moved in the heating path Rh from the inlet 11 toward the outlet 12 by the screw blades 51. During the movement of the treatment object W in the heating path Rh, the treatment object W is heated by the columnar body 1, and moisture in the treatment object W is evaporated at the initial stage of movement, and is gradually dried and moved. From the middle period to the latter period, the processed product W is carbonized by heating and carbonized.

  In this case, since the processed object W is heated by the heat from the columnar body 1 to the outside, compared with the case where heat is applied from the outside of the cylindrical body 10, there is no waste of heat dissipation and heat transfer is surely performed. Is carried out, so that the heating efficiency is improved. In addition, as shown in FIG. 5, in this case, the workpiece W moves while being sandwiched between the outer surface of the columnar body 1 and the inner surface of the cylindrical body 10, so that it is rubbed against the outer surface of the columnar body 1 and the inner surface of the cylindrical body 10. That is, it proceeds while rubbing against the outer surface of the columnar body 1 and the inner surface of the cylindrical body 10, so that the heat conduction to the processed object W is sufficiently performed, and the heating efficiency is also improved in this respect. Furthermore, since the processed product W is dry-distilled in the heating path Rh, it does not burn up as compared with the case where it is directly heated with combustion gas, and is surely carbonized. Therefore, the yield of carbide generation is improved.

  Further, in the heating path Rh, a generated gas containing water vapor is generated from the processed material W. However, since the suction fan 71 of the suction device 70 is connected to the hopper 13, the inside of the hopper 13 has a negative pressure, and the generated gas is It is introduced into the hopper 13 through the gap S between the screw blade 51 and the columnar body 1, and is sucked and discharged by the suction fan 71 through the hopper 13. In this case, since the generated gas passes through the processed product W in the hopper 13, heat exchange with the processed product W is performed, so that the processed product W is heated to some extent. The heating efficiency in Rh is further improved.

  Further, as shown in FIG. 1, the generated gas containing water vapor sucked by the suction device 70 reaches the gas-liquid separation device 80, and the liquid mainly composed of water is separated by the cyclone tower 81. The liquid is recovered from the recovery port 83 of the cyclone tower 81 in a timely manner. The gas exhausted from the exhaust pipe of the cyclone tower 81 is sucked into the burner device 61, reaches the combustion air intake side of the burner device 61, and is mixed with the combustion air of the burner device 61. Therefore, since the heat of the gas can be used, the combustion efficiency can be improved accordingly, and harmful components in the gas can be thermally decomposed in the combustion gas. Further, since the generated gas is separated into gas and liquid and exhausted, the generated gas can be exhausted after being purified.

  As shown in FIG. 3, the red-hot-processed product W carbonized in the heating path Rh falls from the outlet 12 of the heating path Rh to the receiving port 23 of the cooling path Rc. The outer cylinder 20 is rotated by the rotation mechanism 40, and the inner tube 21 of the outer cylinder 20 is tapered so as to expand from the outlet 12 side to the inlet 11 side of the heating path Rh. The workpiece W is gradually moved from the receiving port 23 toward the discharge port 24 by the rotation of the body 20 and cooled. In this cooling process, the workpiece W is exposed to air, so that carbonization is promoted. The cooled processed product W is sequentially discharged from the discharge port 24. In this case, since the processed product W can be taken out after being cooled in the outer cylindrical body 20, it is not necessary to provide a separate cooling line, thereby saving the labor of the apparatus.

  FIG. 6 shows another example of the moving means 50 in the heat treatment apparatus according to the embodiment of the present invention. In this case, instead of the continuous screw blades 51, a large number of rectangular blades 51 are arranged on the inner surface of the cylindrical body 10 so as to advance the workpiece W by the rotation of the cylindrical body 10 and project. It has been made. The hopper 13 is inclined toward the heating path Rh, and the workpiece W is directly introduced into the inlet 11 of the heating path Rh. According to this, since there are intervals between the numerous rectangular blades 51, the flow of the generated gas from the workpiece W becomes smooth. Other actions and effects are the same as described above.

In the above embodiment, the outer cylinder 20 is provided to form the cooling path Rc. However, the present invention is not necessarily limited to this, and the outer cylinder 20 may not be provided. In this case, the carbide generated in the heating path Rh is cooled in another line. However, in order to increase the efficiency of the line, it is more preferable to provide the outer cylinder 20 and include the cooling path Rc. Further, the moving means 50 is not limited to the above-described example, and can be appropriately changed in design.
Further, the treated product W has been described in the case of livestock manure, but is not necessarily limited thereto, and can be applied to various wastes. Of course, the present invention is not limited to waste, and may be applied to various processed products.

Forming a movable heating path, and moving means for moving the processing object supplied to the inlet of the heating path toward the outlet of the heating path, and heating the processing object moving in the heating path the heat has a configuration which is adapted to carbonize by dry distillation of the set heat applying means for applying a columnar body only, treated with heating path.

Thus, for example, when an organic combustible material having moisture is carbonized by heat treatment, for example, heat is applied to the columnar body by the heat applying means. In this state, the processing object is supplied to the inlet of the heating path, and the processing object is moved toward the outlet of the heating path by the moving means. During the movement of the processed material in this heating path, the processed material is heated, and the moisture in the processed material is evaporated in the initial stage of the movement and gradually dried. Things are carbonized and carbonized.

In addition, since the heat applying means is configured to apply heat to the columnar body, heat is transmitted from the inside toward the outside, so compared to the case where heat is applied from the outside of the cylindrical body. In addition, there is no waste of heat dissipation and heat transfer is performed reliably, so that heating efficiency is improved. In addition, the structure of the apparatus can be simplified.
In addition, when it is configured to apply heat to the cylindrical body, heat is transmitted to the processed material on the columnar body side, but heat escapes also to the outside of the cylindrical body, so when heat is applied to the cylindrical body Compared with, the heat transfer rate to the processed product is slightly inferior. Further, since the outside of the cylinder must be covered with a heat insulating material or the like, the apparatus becomes complicated. However, compared with the prior art, heat transfer is reliably performed, and the heating efficiency is improved.

And it forms on SL columnar body tube, said heat applying means, and configured to include a burner device for supplying an internal combustion gases from the outlet side of the front end of the heating path of the columnar body. As a result, heat is applied to the columnar body by the combustion gas of the burner device, and heat is transmitted from the columnar body to the processed material, so that heat is transmitted from the inside to the outside. Compared with the case where heat is applied from the outside of the body, there is no waste of heat dissipation, heat transfer is performed reliably, and thus the heating efficiency is improved. Moreover, since it can comprise by making a columnar body into a tubular body and installation of a burner apparatus is easy, the structure of an apparatus can also be simplified.

Furthermore, in this invention, it is set as the structure provided with the suction device which attracts | sucks the generated gas generated in the said heating path | route from the entrance side of this heating path | route. Even if generated gas containing water vapor is generated from the processed material in the heating path, the generated gas can be forcibly sucked and discharged to the outside. In addition, since the generated gas is allowed to pass through the untreated material, heat exchange with the untreated material is performed, and the treated material is heated to some extent. The heating efficiency at is further improved.

Further, a hopper for supplying a processed material to the inlet of the heating path is provided, and the suction device is configured to suck the generated gas generated in the heating path through the hopper. As a result, the generated gas passes through the processed material in the hopper, so that heat exchange with the processed material is performed, so that the processed material is heated to some extent, and thus the heating efficiency in the heating path of the processed material is improved. It can be further improved.
If necessary, the treated product is composed of an organic combustible material, and the treated product is carbonized in the heating path to obtain a carbide. As a treated product, a fluid organic combustible material containing water such as livestock waste, food waste, sewage sludge, etc. can be heat treated to obtain a carbide.

In the above embodiment, since the outer cylinder 20 is provided to form the cooling path Rc, the carbide generated in the heating path Rh is cooled by another line without providing the outer cylinder 20. in comparison, the increase the efficiency of the line, yo more preferable. Further, the moving means 50 is not limited to the above-described example, and can be appropriately changed in design.
Further, the treated product W has been described in the case of livestock manure, but is not necessarily limited thereto, and can be applied to various wastes. Of course, the present invention is not limited to waste, and may be applied to various processed products.
