BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a configuration drawing that shows the carbonizing system of the present invention.
FIG. 2 is a configuration drawing that shows the carbonizing system of a modification of the present invention.
DETAILED DESCRIPTION OF WORKING EXAMPLES OF THE INVENTION
Based on the attached drawings, the details of the working examples of the present invention are as described below.
The present invention relates to an apparatus carbonizing forest residues such as stems or branches cut from trees. Carbonization means a pyrolysis process conducted to remove residual moisture and gas from raw materials 100, i.e., waste woods such as forest residues that are cut into small pieces.
In the present invention, a combustion tube 10 that contains a transfer screw 22 in the inner shell 11 has a partition plate 14 between the inner shell 11 and the outer shell 12. The inner shell 11 and the outer shell 12 are placed on the horizontal axis and there is formed a heating space between the shell 11 and the outer shell 12. The heating spaces of the combustion tube 10 are divided by the partition plates 14, and a hopper 16 is connected to the inner shell 11 in the upstream layer. The hopper 16 may have a cutter (drawing omitted) that cuts raw materials 100 into chips. The transfer screw 22 installed horizontally in the inner shell 11 is connected to a motor 24 with a decelerator 26 installed on one side.
It is recommended to form three heating spaces of the combustion tube 10 by using two insulated partition plates 14. Dividing the heating spaces of the combustion tube 10 into the upstream layer, the middle layer and the downstream layer helps to pyrolyze massive raw materials 100 sequentially in a short time. The partition plates 14 not only support the inner shell 11 and the outer shell 12 but also maintain the temperature and the upstream layer, the middle layer and the downstream layer independently in the heating spaces by the insulation function.
In the present invention, each burner 31 is installed in the heating spaces that are divided by the partition plates 14. The drawings herein show only one burner 31 in each heating space, but it is also possible to use multiple burners. The temperature of the upstream layer is maintained approximately at 200-600 C, desirably at 250-400 C to evaporate moisture as the previous stage of pyrolysis. The temperature of the middle layer is maintained approximately at 400-900 C, desirably at 500-700 C to perform the primary pyrolysis process. The temperature of the downstream layer is maintained approximately at 300-800 C, desirably at 400-600 C to perform the secondary pyrolysis process. The temperature of each heating space depends on the type, temperature and water content of raw materials 100 and may be adjusted by using a hot air inducer 33 installed closely to the burner 31. The hot air inducer 33 has a structure that prevents the direct contact of flammables with raw materials 100 and changes the hot air volume.
The heating spaces (upstream layer, middle layer and downstream layer) of the combustion tube 10 have several sensors that measure temperature, which are omitted from the drawings.
The inner shell 11 has exhaust pipes 18 that emit gas from several points to the outside. The exhaust pipes 18 are composed of several independent pipes or one integrated pipe system.
In the present invention, a cooling box 40 that performs cooling during the transfer to the transfer screw 42 is connected with the combustion tube 10 with exhaust pipes 28 installed in the downstream layer. The exhaust pipes 28 are connected from the bottom of the downstream layer of the combustion tube 10 to the top of the upstream of the cooling box 40.
Like the combustion tube 10, the cooling box 40 also contains the transfer screw 22 that transfers raw materials 100. The transfer screw 42 is connected to the motor 44 with a decelerator 46 installed on one side. The cooling box 40 uniformly cools the carbides of approximately 400 C discharged in powder form from the combustion tube 10.
The detailed configuration of the present invention is as follows. The cooling box 40 has a cooling ring 51 with ring-shaped flow path, a nozzle 52 that is installed in the cooling ring 51 and a spray controller 56 that controls the spray status of cooling media through the nozzle 52. The cooling ring 51 that is installed on the outer surface of the cooling box 40 has several nozzles 52 on the inner surface. Cooling media basically use water and may contain slightly viscous liquid and air. The cooling ring 51 is connected to the spray controller 56 with the cooling tube 54 is installed. The spray controller 56 controls the volume and pressure of sprayed water through the nozzle 52. Raw materials 100 flow in from the upstream layer of the cooling box 40 at approximately 400 C and flow out from the downstream layer at approximately 150 C.
If the length of the cooling box 40 is long, it is possible to use multiple cooling media 50. In this case, it is possible to see that the nozzle 52 at the upstream layer sprays water or slightly viscous liquid-containing water, while the nozzle 52 at the downstream layer sprays air. It is also possible to spray a viscosity-maintaining ingredient or a combustion-promoting ingredient if using other raw materials than water or air.
The cooling box 40 may have a discharge tank 48 at the downstream layer to convert fuel into the desired type of pellets. The discharge tank 48 has the function to discharge carbides in circular or angular form and cut them in a certain length. After passing the discharge tank 48, carbides are converted into pellets of approximately 70-120 C (desirably 80-100 C).
As shown in FIG.2, which shows a modification of the present invention, the cooling box 40 may have several height-adjustable legs 35, some of which have a buffer 37. In the present invention, the horizontal combustion tube 10 is advantageous to operate the transfer screw 22. However, if the outer shape is bigger, the burden on the motor 24 is greater.
Considering this problem, it is desirable to install several height-adjustable legs 35 at the bottom of the combustion tube 10. The height-adjustable legs 35 are installed by using height-adjustable jacks or simple bolts. Especially, it is recommended to use a buffer 37 for the height-adjustable legs in the middle layer, except the upstream and downstream layers. A
simple spring may be used for the buffer 37, which reduces vibration that occur from the combustion tube 10.
Like the combustion tube 10, it is also possible to install height-adjustable legs 35 at the bottom of the cooling box 40. In any case, flexible pipes are included in the exhaust pipes 28 for the relative motions between the combustion tube 10 and the cooling box 40.
The operating procedure is as follows. Raw materials 100 flow into the upstream layer of the inner shell 11 through the hopper 16 and go through 3-phase pyrolysis processes while transferred by the transfer screw 22 at the designated speed. They are then discharged into the cooling box 40 in carbide form (energy-generating fuel) through the exhaust pipes 28 and converted into pellets, etc. while transferred again by the transfer screw 42 at the designated speed.
As described above, fuel is generated continuously in the discharge tank 48 of the cooling box 40 after sequential pyrolysis processes although raw materials 100 are put in the hopper 16 continuously. Since the length of the combustion tube 10 may range from a few meters to 30m or longer, the present invention is advantageous to process raw materials 100 of massive forest residues efficiently.
There are other working examples of the present invention besides the given example, and it is obvious to a person with common knowledge in the field of this technology that the present invention is variously modifiable and transformable without deviation from the idea and the scope of the present invention. Therefore, the examples of such modifications and transformations fall into the scope of patent claims for the present invention.

The heating spaces (upstream layer, middle layer and downstream layer) of the combustion tube 10 have several sensors that measure temperature, which are omitted from the drawings.
The inner shell 11 has exhaust pipes 18 that emit gas from several points to the outside. The exhaust pipes 18 are composed of several independent pipes or one integrated pipe system.
In the present invention, a cooling box 40 that performs cooling during the transfer to the transfer screw 42 is connected with the combustion tube 10 with exhaust pipes 28 installed in the downstream layer. The exhaust pipes 28 are connected from the bottom of the downstream layer of the combustion tube 10 to the top of the upstream of the cooling box 40.
Like the combustion tube 10, the cooling box 40 also contains the transfer screw 22 that transfers raw materials 100. The transfer screw 42 is connected to the motor 44 with a decelerator 46 installed on one side. The cooling box 40 uniformly cools the carbides of approximately 400 C discharged in powder form from the combustion tube 10.
The detailed configuration of the present invention is as follows. The cooling box 40 has a cooling ring 51 with ring-shaped flow path, a nozzle 52 that is installed in the cooling ring 51 and a spray controller 56 that controls the spray status of cooling media through the nozzle 52. The cooling ring 51 that is installed on the outer surface of the cooling box 40 has several nozzles 52 on the inner surface. Cooling media basically use water and may contain slightly viscous liquid and air. The cooling ring 51 is connected to the spray controller 56 with the cooling tube 54 is installed. The spray controller 56 controls the volume and pressure of sprayed water through the nozzle 52. Raw materials 100 flow in from the upstream layer of the cooling box 40 at approximately 400 C and flow out from the downstream layer at approximately 150 C.
If the length of the cooling box 40 is long, it is possible to use multiple cooling media 50. In this case, it is possible to see that the nozzle 52 at the upstream layer sprays water or slightly viscous liquid-containing water, while the nozzle 52 at the downstream layer sprays air. It is also possible to spray a viscosity-maintaining ingredient or a combustion-promoting ingredient if using other raw materials than water or air.
The cooling box 40 may have a discharge tank 48 at the downstream layer to convert fuel into the desired type of pellets. The discharge tank 48 has the function to discharge carbides in circular or angular form and cut them in a certain length. After passing the discharge tank 48, carbides are converted into pellets of approximately 70-120 C (desirably 80-100 C).
As shown in FIG.2, which shows a modification of the present invention, the cooling box 40 may have several height-adjustable legs 35, some of which have a buffer 37. In the present invention, the horizontal combustion tube 10 is advantageous to operate the transfer screw 22. However, if the outer shape is bigger, the burden on the motor 24 is greater.
Considering this problem, it is desirable to install several height-adjustable legs 35 at the bottom of the combustion tube 10. The height-adjustable legs 35 are installed by using height-adjustable jacks or simple bolts. Especially, it is recommended to use a buffer 37 for the height-adjustable legs in the middle layer, except the upstream and downstream layers. A
simple spring may be used for the buffer 37, which reduces vibration that occur from the combustion tube 10.
Like the combustion tube 10, it is also possible to install height-adjustable legs 35 at the bottom of the cooling box 40. In any case, flexible pipes are included in the exhaust pipes 28 for the relative motions between the combustion tube 10 and the cooling box 40.
The operating procedure is as follows. Raw materials 100 flow into the upstream layer of the inner shell 11 through the hopper 16 and go through 3-phase pyrolysis processes while transferred by the transfer screw 22 at the designated speed. They are then discharged into the cooling box 40 in carbide form (energy-generating fuel) through the exhaust pipes 28 and converted into pellets, etc. while transferred again by the transfer screw 42 at the designated speed.
As described above, fuel is generated continuously in the discharge tank 48 of the cooling box 40 after sequential pyrolysis processes although raw materials 100 are put in the hopper 16 continuously. Since the length of the combustion tube 10 may range from a few meters to 30m or longer, the present invention is advantageous to process raw materials 100 of massive forest residues efficiently.
There are other working examples of the present invention besides the given example, and it is obvious to a person with common knowledge in the field of this technology that the present invention is variously modifiable and transformable without deviation from the idea and the scope of the present invention. Therefore, the examples of such modifications and transformations fall into the scope of patent claims for the present invention.
