[0012]
DETAILED DESCRIPTION OF THE INVENTION
The present invention aims to carbonize wood chips, wood waste materials, and other industrial waste containing carbonaceous matter into high-quality charcoal, and continuously and line-process them with a tunnel-type processing device. .
[0013]
That is, a working chamber for filling carbonized material is provided on one side of the processing tunnel, and then a container filled with the material is placed in a preheating furnace through a preparation chamber (preheating chamber) on which a cart is placed and sealed. In the preheating furnace, an endothermic gas (a gas used for cooling) and a heated exhaust gas are used to heat the container to a predetermined temperature and maintain that state (for example, for 60 to 120 minutes) to allow dry distillation gas and tar. Discharge as much as possible. This dry distillation gas is refined and used as a heating source for the heating furnace (general gas or kerosene is used for the initial start-up), and exhaust gas during the dry distillation is not emitted at all, and the fuel gas as the heating source is almost supplied by dry distillation gas. It will be. Further, the tar generated by refining the dry distillation gas and the tar taken out from the preheating furnace are collected together and used in the same manner as general tar.
[0014]
After preheating sufficiently as described above and discharging the carbonization gas, etc., the door is opened and the container is pushed into the heating furnace together with the carriage. In this case, by pushing the carriage in the preheating chamber (or stuffing chamber), the trolley in the preheating furnace and the heating furnace also moves, so there is no need to provide power for each, and simply the preheating furnace and the stuffing chamber (or preheating chamber). ), The doors of the preheating furnace and the heating furnace, the heating furnace and the cooling chamber are opened, and one truck is moved forward, so that heat loss due to the movement of the carriage can be minimized. In this way, the next carriage enters without rapidly cooling the inside of the heating furnace by taking in and out the carriage, so that heat loss at the time of replacement can be minimized.
[0015]
In the above, the pipes that cut off heat between the container and the carriage and lead the dry distillation gas etc. from the container to the outside are all made of refractory material, so even if used continuously for a long time, there is little damage and it will be used for a long time be able to.
[0016]
The connection between the inside and outside of the tunnel in the above is only the discharge of dry distillation gas and tar and the circulation of endothermic gas in the cooling chamber, so there are very few internal and external connection parts, little heat loss, and special provisions for providing connection parts. There is no problem.
[0017]
[Example 1]
An embodiment of the present invention will be described with reference to FIG. Carbonized materials such as wood chips, wood scraps, buckwheat, and other wooden waste (small items are pressure-molded to make them 3 cm square or larger, for example) are packed in a container on a trolley in a stuffing room, and this container is preheated Wait in the previous preheating room.

For example, if the preheating furnace is preheated to 250 ° C. to 400 ° C., the dry distillation gas and tar are taken out and sufficiently dry distillation is performed, the doors between the heating furnace, the preheating furnace and the preheating chamber are opened at the same time. After pushing in the table, the doors are closed and preheating is started again, the gas burner is started to start heating, and the inside of the heating furnace is heated to 700 ° C to 1000 ° C. In this case, the combustion gas enters the preheating furnace through a hole provided in the door, heats the preheating furnace, then enters the preheating chamber from the flue, and dissipates from the smoke tube to the outside through the preheating chamber.

In the above, the cooled container is moved forward by one unit, and after the charcoal is taken out at the position advanced by one unit from the cooling position, the container and the carriage are returned to the stuffing chamber and are circulated for use.
[0021]
In the above, stuffing, preheating, heating, and cooling are performed in the same time zone, so that charcoal is efficiently and continuously produced.
[0022]
The dry distillation gas generated in the preheating furnace described above is used as a gas fuel after purification. However, if the amount of dry distillation gas discharged and the amount of gas required for the heating source are substantially the same, it can be operated extremely economically. . When the dry distillation gas increases at a time, it is accommodated in a gas tank for adjustment. When the dry distillation gas is temporarily low, gas fuel or oil fuel is replenished.

Can be insulated.
[0032]
When the preheating chamber 11a and the connecting pipe 9 of each container 5 in the stuffing chamber 11 are connected, the valve body 65 is rotated by rotating the ohm 69 and the ohm gear 68, and the connection of the valves is shown in FIG. If it does in this way, the preheating gas in the container 5 of the preheating chamber 11a will enter the preheating chamber 11a without entering the container 5 in the stuffing chamber 11, and preheat it there.
[0033]
Since the valve body 65 of the connecting pipe 9 of the container 5 in the preheating furnace 12 is also rotated as shown in FIG. 5C, the dry distillation gas and tar in the container in the preheating furnace 12 are the same as those shown in FIG. c) It flows as indicated by the middle arrow 72 and is taken out to the outside (gas treatment system) through the exhaust gas pipe 28.
[0034]
Next, since the valve body in the heating furnace 13 is rotated as shown in FIG. 5 (d), the dry distillation gas flows as shown by an arrow 73 in the figure, and passes through the connecting pipe 9 and the flexible pipe 74 to the preheating furnace. The container 5 in 12 is heated and taken out from the connection pipe 9 to the outside through the exhaust pipe 28 through the path.
[0035]
In the above, when the preheating and heating are completed, the respective doors are opened and then the trolley in the stuffing chamber is pushed out by one in the direction of arrow 32, so that the trolley 2 of the heating furnace 13 is preheated to the cooling chamber 4.

In this way, the container 5 is cooled, the container 5 is cooled by absorbing heat, flows in the fixed pipe 8 as indicated by an arrow 39, enters the preheating pipe 16 again, and circulates to heat the preheating furnace 12.
[0037]
After the inside of the heating furnace 13 is heated by the burners 20 and 20a, the exhaust gas passes through the communication hole 17 of the shut-off door 15b and enters the preheating furnace 12 as indicated by an arrow 39 and heats the inside of the preheating furnace 12. Then, the air enters the preheating chamber 11a from the flue 18, and is discharged from the chimney 18a on the upper side as indicated by an arrow 40.
[0038]
Since the inside of the preheating furnace 12 is heated to a predetermined temperature (250 ° C. to 400 ° C.) by the endothermic gas and the heated exhaust gas as described above, the carbonized material (for example, wood chips) is dry-distilled to discharge the dry-distilled gas. , Exhaust tar (or tar gas or wood acetic acid, etc.). Accordingly, the dry distillation gas is conveyed to the treatment device via the connection pipe 9 and the exhaust gas pipe 28, and the tar is connected to the exhaust gas pipe 28 via the drain pipe 10 and processed.
[0039]
The dry distillation gas collects in the exhaust head 7, moves down the fixed pipe 8 as indicated by arrow 41, moves to the exhaust gas pipe 28 through the connecting pipe 9, and passes through the exhaust gas pipe 28 as indicated by arrows 42 and 43. The tar is separated by being cooled by the cooler 27, and only the gas passes through the diffusion gas pipe 25 as indicated by arrow 44, rises in the water in the water tank 24a as indicated by arrow 45, and accumulates in the gas tank 24. It passes through the gas pipe 22 as shown by an arrow 46 and is burned by the gas burner 20a. In this case, if the amount of gas generated is larger than the amount of combustion, it is stored in the gas tank 24. If the amount of gas generated is small, the amount stored in the gas tank 24 is raised to adjust the unbalance in supply and demand ( When it is high) or descend (when low).
[0040]
When the pipe in the cooler 27 becomes clogged or dirty (mostly time-controlled), steam generated by the steam generator 30 is pressurized and fed into the cooler 27 as indicated by arrows 47 and 48, and the valve 49 is closed, the valve 50 is opened, and all the dirt and the like in the cooler 27 are removed as indicated by an arrow 63. If cleaning is performed in this manner, the cleaning time can be controlled by a timer or manually.
[0041]
In the above, when tar comes out from the drain pipe 10 through the exhaust gas pipe 28, the tar 31 passes through the cooler 28, is cooled by the water tank 26, and accumulates at the bottom of the water tank 26. The water is discharged from the faucet 51 as indicated by an arrow 64.
[0042]
In the above, in order to advance the carriage, each door is opened, and each carriage in the cooling chamber, the heating furnace, the preheating furnace, the preheating chamber, and the stuffing chamber is advanced by one. Thus, since the whole can be moved by intermittently moving it by one carriage, heat loss can be reduced as much as possible.
[0043]
Next, another embodiment of the connection between the connecting pipe 9 and the exhaust gas pipe 28 will be described with reference to FIG. When the auxiliary pipe 80 is slidably opposed to the connecting pipe 9a and the handle 81 of the auxiliary pipe 80 is unlocked (not shown), the auxiliary pipe 80 is moved in the direction of the arrow 83 by the spring 82. And the tip is inserted into the connecting pipe 9a. In the figure, 84 is a groove of the handle 81.
[0044]
Another example of connection between the connection pipe 9 and the base end of the exhaust gas pipe 28 will be described with reference to FIG. A valve rod 9c and a coupling rod 9a are sequentially installed in series at the distal end of the connection pipe 9, and a valve plate 51 is rotatably mounted on the valve shaft 52 by a shaft 52 in the valve rod 9c. Since the spring 53 is fitted and the shaft 52 is urged in the direction of the arrow 54, when no external force is applied to the valve plate 51, the spring 53 is always closed as shown in FIG. ing.
[0045]
The connecting rod 9a can be fitted at the distal end of the auxiliary pipe 55, and the auxiliary pipe 55 is slidably inserted into the connecting pipe 56 connected to the base end of the exhaust gas pipe 28. A grip 57 fixed to the auxiliary pipe 55 is loosely fitted in a groove 56 a parallel to the axis of the connection pipe 56.
[0046]
In the above structure, if the connecting pipe 9 stops at a fixed position, when the grip 57 is gripped and moved in the direction of the arrow 58, the auxiliary pipe 55 is also moved in the direction of the arrow 59, and the tip thereof is the valve plate 51. Since the valve plate 51 rotates the valve shaft 52 in the direction of the arrow 60 against the spring 53, the valve plate 51 also rotates in the same direction, and the connecting pipe 9 and the exhaust gas pipe 28 communicate with each other. Therefore, the dry distillation gas generated in the container 5 flows as indicated by arrows 61 and 62 and enters the cooler 27 through the exhaust gas pipe 28.
[0047]
In the above-described embodiment, the connection between the connection pipe 9 and the exhaust gas pipe 28 has been described. However, the connection to the drain pipe 10 or the gas receiving port of the preheating pipe 16 is exactly the same. The connection structure is not particularly limited, and any connection structure can be adopted as long as it is simple, reliable, and easy to operate. It is even better if this connection or disconnection can be made automatically.
[0048]
