Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to industrial waste and garbage discharged from companies, factories, hotels, inns, restaurants, households, etc., without causing pollution and harmless and odorless. The present invention relates to an apparatus for carbonizing. More specifically, the present invention relates to a carbonization apparatus capable of easily and inexpensively converting various wastes into high-quality carbide.

[0002]

2. Description of the Related Art The amount of waste discharged from factories and households has been steadily increasing with the progress of science in recent years, and how to treat the waste is not limited to the parties concerned. , Is one of the social issues. Therefore, various researches and developments have been made on the waste disposal method.

[0003] Above all, in the method of treating waste by carbonizing, it is possible to easily treat waste as carbide by using a relatively simple apparatus, and the carbon produced by the treatment is not easily treated. Since it is harmless and odorless and leads to volume reduction of waste, it is also used by local governments and general companies.

Here, in the conventional carbonization apparatus,
Usually, carbonization is performed at about 300 to 400 ° C.

[0005] However, in the carbide produced by the carbonization treatment at 300 to 400 ° C., the volatile matter is often still contained in the carbide at about 20 to 30%. ), But
The carbide has a problem that it is often poor in practical use as charcoal. This is because it is often difficult to completely remove the volatile components contained in the generated carbide at a temperature of 300 to 400 ° C. at the time of carbonization.

In such a case, the carbonization chamber is set to 400
It is possible to remove volatile components remaining in the carbide by raising the temperature to a high temperature of at least 700 ° C. (for example, about 700 to 900 ° C.). It is difficult to withstand a high temperature of 900 ° C., and it is theoretically possible to provide a carbonized chamber that can withstand a high temperature of about 700 to 900 ° C. It is conceivable that providing high heat resistance is considerably expensive in terms of cost.

[0007] It is also conceivable to provide a new carbonization device in addition to the conventional carbonization device to reprocess the carbide generated from the conventional carbonization device. 700 to 90
Energy for high temperature of 0 ° C is required separately,
Again, it is not economically favorable.

[0008]

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above circumstances, and when carbonizing waste, it is possible to obtain a carbide having higher quality and practicality than conventional carbides. It is an object of the present invention to provide a carbide treatment device which is excellent in economy and workability.

[0009]

In order to achieve the above object, according to the present invention, in claim 1, a carbonization chamber for performing at least carbonization processing and a heating chamber provided around the carbonization chamber to heat the carbonization chamber are provided. A primary carbonization device for carbonizing the object to be treated, a gas treatment device for processing the generated gas generated in the primary carbonization device to a high-temperature gas, and a gas Utilizing the heat of the high-temperature gas generated in the processing device, a secondary carbonizing device for converting the coarse carbides generated in the primary carbonizing device into high-quality carbides, provide.

[0010] The carbonizing apparatus in the present invention has at least a primary carbonizing apparatus, a gas processing apparatus, and a secondary carbonizing apparatus. Then, first, the waste is put into the primary carbonization device and heated in the primary carbonization device to become coarse carbide. Here, the crude carbide refers to a carbide containing more volatile components than generally used charcoal. In the primary carbonization apparatus, carbonization is generally performed at about 300 to 400 ° C., and about 20 to 30% of volatile components are contained in the crude carbonized at that temperature.

In the present invention, first, crude carbide is generated in the primary carbonization device, and the generated gas generated in the primary carbonization device is processed by a gas processing device. This is because the gas generated when generating coarse carbides in the primary carbonization device often contains harmful substances depending on the type of processing target, and releasing it directly to the atmosphere has environmental health problems. Because. The gas processing apparatus according to the present invention can remove harmful substances contained in the generated gas by heating and burning the generated gas. Therefore, the generated gas processed by the gas processing apparatus has an energy Becomes a reusable high-temperature gas (usually 700 to 900 ° C.).

[0012] The carbonization apparatus of the present invention is characterized in that a secondary carbonization apparatus utilizing heat of a high-temperature gas generated by being processed by the gas processing apparatus is provided. By providing a secondary carbonization device,
Crude carbide generated in the primary carbonization device by the heat of the high-temperature gas can be recarbonized. By performing the re-carbonization treatment, volatile components contained in the crude carbide can be removed, and it can be used to obtain high-quality carbide.

As described above, by providing the secondary carbonization device in addition to the primary carbonization device and the gas treatment device, it is possible to produce a carbide having a higher quality than the carbide produced in the conventional carbonization device. The generated gas generated in the apparatus and subjected to the heating and burning treatment for environmental hygiene reasons can be effectively used as a high-temperature gas.

In the first aspect of the present invention,
As described in claim 2, it is preferable that the high-temperature gas used for producing high-quality carbide in the secondary carbonization device be sent to the heating chamber in the primary carbonization device as a heating chamber gas.

[0015] With such a structure of the carbonization treatment device, the generated gas generated in the primary carbonization device can be used as a high-temperature gas in the secondary carbonization device for producing high-quality carbides. By returning the high-temperature gas used in the carbonizer to the primary carbonizer as a heating chamber gas,
It can be used as heat energy in a heating chamber used to convert the processing object into a coarse carbide. That is, when the generated gas generated in the primary carbonization device is processed by the gas processing device, the temperature of the generated gas becomes extremely high (about 700 to 900 ° C.) (here, high-temperature gas), and the secondary gas is generated. It is suitable for producing good-quality carbide in a carbonization apparatus. Then, the temperature of the high-temperature gas used for producing high-quality carbide in the secondary carbonization device is lowered to about 300 to 400 ° C. (here, it becomes a gas for a heating chamber). The temperature of this gas is a temperature necessary for turning the treatment target (waste) into coarse carbide in the primary carbonization apparatus as described above, and the efficiency is improved by returning the heating chamber gas to the heating chamber in the primary carbonization apparatus. This makes it possible to carry out carbide treatment well.

In the first or second aspect of the present invention, as described in the third aspect, it is preferable that the primary carbonizing device is a batch type carbonizing device.

In the present invention, the primary carbonizing device is not particularly limited, and any primary carbonizing chamber can be used. Above all, the batch type carbonization chamber
Since the operability is good and most of the existing carbonization chambers are of a batch type, it is preferable because it is easy to modify even the carbonization chamber of the present invention.

Further, in the third aspect of the invention, as described in the fourth aspect, it is preferable that the secondary carbonization apparatus of the present invention is provided with a carbide container that can be taken in and out. .

The carbonizing apparatus of the present invention is characterized in that the coarse carbonized material generated in the primary carbonizing device is converted into high quality carbide in the secondary carbonizing device. In the present invention, the means for transferring the coarse carbide generated in the primary carbonization device to the secondary carbonization device is not particularly limited, and any transfer means can be used. In particular, when the primary carbonization device is of a batch type as described above, it is preferable that a carbide container that can be taken in and out of the secondary carbonization device is provided. When removing the coarse carbide produced in the primary carbonization device, the carbide container is carried to the coarse carbide outlet of the primary carbonization device, and the coarse carbide is directly charged into the carbide container, and then directly into the secondary carbonization device. This is because a high-quality carbide can be obtained by installing the metal carbide. That is, by using the carbide container, the operability can be improved and the operation can be performed more easily.

[0020]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a carbonization apparatus of the present invention will be specifically described with reference to the drawings.

FIG. 1 is a schematic diagram for explaining a carbonization apparatus of the present invention.

The carbonization apparatus 1 of the present invention includes a primary carbonization apparatus 10 for converting a target object into a coarse carbide, a gas processing apparatus 20 for processing a generated gas generated in the primary carbonization apparatus 10, It is roughly constituted by a secondary carbonizing device 30 for converting the coarse carbides generated by the primary carbonizing device 10 into high-quality carbides by utilizing the heat of the high-temperature gas processed in the gas processing device 20.

As described above, by providing the secondary carbonization device in addition to the primary carbonization device and the gas treatment device, it is possible to easily produce a high-quality carbide as compared with the carbide produced in the conventional carbonization device. The generated gas generated in the primary carbonization device can be effectively used.

Hereinafter, the [1] primary carbonization device, [2] gas treatment device, and [3] secondary carbonization device constituting the carbonization device of the present invention will be described in detail.

[1] Primary Carbonization Apparatus The primary carbonization apparatus 10 shown in FIG. 1 is a batch-type primary carbonization apparatus, and a carbonization chamber 12 for carbonizing the object 11 to be treated.
And a heating chamber 13 installed around the carbonization chamber 12 for heating the carbonization chamber 12.

The carbonization chamber 12 has a processing object input port 14 for charging the processing object 11 into the carbonization chamber.
And a stirrer 15 for turning the processing target substance supplied from the processing target input port 14 into carbide while stirring, and a coarse carbide outlet 16 for extracting coarse carbide generated in the primary carbonization device, A generated gas exhaust port 17 for discharging generated gas generated in the carbonization chamber 12 is provided. The generated gas exhaust port 17 is connected to a pipe H1 for connecting to a gas processing device 20 described later.

In the present invention, the processing object 11 is not particularly limited. Among them, preferred examples include industrial waste discharged from factories and / or general waste such as garbage discharged from households. By turning waste into high-quality charcoal, it is possible not only to reduce the volume of waste, but also to reuse such waste, and to reduce problems such as environmental pollution by waste. Because.

The present invention is not particularly limited in terms of the shape and structure of the carbonization chamber 12 in the batch type primary carbonization apparatus 10 shown in FIG. 1 as long as the object to be treated can be carbonized. Any carbonization chamber may be used. However, in the usual case, the object of treatment (general waste such as garbage, industrial waste discharged from factories, etc.)
Since carbonization requires a temperature of 300 to 400 ° C., the carbonization chamber itself needs to have heat resistance to withstand a temperature of 300 to 400 ° C.

Here, the stirrer 15 is not always necessary for the primary carbonizing device of the present invention, and its installation is optional. This is preferable because heat can be uniformly applied to the entire processing object 11. Further, the piping H1 connected to the generated gas exhaust port to communicate with a gas processing device described later is not an essential configuration of the present invention, and its shape and the like are not particularly limited. For example, when the primary carbonization device and a gas processing device described later are adjacent to each other, it is not necessary to particularly use the pipe H1.

A heating chamber 13 used for heating the carbonizing chamber 12 is provided around the carbonizing chamber 12 described above. The heating chamber 13 has a burner 18 as a heating means. Further, an exhaust tower 19 for exhausting the inside of the heating chamber 13 is provided.

In the present invention, the heating chamber is not particularly limited.
Any material can be used as long as it can be heated to 400 ° C., and a known heating chamber can be used. Also, the present invention is not particularly limited with respect to the burner 18 used in the heating chamber 13,
Heating means other than the burner may be used.

By carbonizing the object to be treated by using the primary carbonizing device, the volume of the object to be treated is about 1/5 to 1/1.
It is possible to obtain a crude carbide having a value of 10.

In the above, the batch type primary carbonizing device 1
However, the batch type primary carbonizing device 10 is an example of the primary carbonizing device in the present invention, and the present invention is not limited to this, and a continuous type carbonizing device may be used. Examples of the continuous carbonization device include a rotary kiln type carbonization device.

[2] Gas Processing Apparatus Next, the gas processing apparatus will be described.

The gas treatment device is provided so as not to be harmful to the human body and the environment when releasing the gas generated when the primary carbonization device produces crude carbide into the atmosphere. Gas processing device 20 shown in
Shows an example of a gas processing apparatus that can be used in the present invention.

The gas treatment device 20 is provided with a gas inlet 21 for introducing the generated gas generated in the carbonization chamber 12 of the primary carbonization device 10 into the gas treatment device.
And a burner 22 used for gas processing, and a high-temperature gas outlet 23 for discharging the gas after the processing. The gas inlet 21 is connected to a pipe H1 for communicating with the generated gas outlet 17 of the coking chamber 12 in the primary carbonizer 10, and the hot gas outlet 23
Is a pipe H2 for connecting to a secondary carbonization device 30 described later.
Is connected to

The generated gas sent into the gas processing apparatus 20 through the pipe H1 is burned by a burner 22 installed in the processing apparatus, and becomes a smokeless and odorless high-temperature gas. It is discharged from 23. The temperature of the high-temperature gas processed by the gas processing device 20 is in a high temperature state of 700 to 900 ° C. Therefore, in the secondary carbonization device 30 described later, the coarse carbide generated in the primary carbonization device 10 can be made to be a high-quality carbide.

The burner 22 and the like in the gas processing device 20 are not particularly limited, and a known device can be used.

When the object to be treated is an organic waste (eg, plastic), it is also possible to remove tar and the like contained in the gas. In this case, the gas purifying device may be provided as a gas processing device, and the device of the present invention is not particularly limited in the gas purifying device. For example, a commonly used tar reformer or the like can be used (not shown).

[3] Secondary carbonization device Next, the secondary carbonization device will be described.

FIG. 1 shows an example of a secondary carbonizing device that can be used in the present invention.

The secondary carbonizing device 30 shown in FIG. 1 converts the coarse carbide generated in the primary carbonizing device 10 into the secondary carbonizing device 3.
0, a high-temperature gas inlet 32 for feeding the high-temperature gas treated in the gas treatment device 20 into the secondary carbonization device 30;
An exhaust port 33 is provided for discharging the high-temperature gas used for converting the coarse carbide into high-quality carbide in the secondary carbonization chamber to the outside of the secondary carbonization device. The high-temperature gas inlet 32 is connected to a pipe H2 for communicating with the gas processing device. The secondary carbonization device 30 is provided with a carbide container 34 that can be taken in and out. The secondary carbonizing device 30 is preferably formed of a heat-resistant material that can withstand a high temperature of 700 to 900 ° C.

FIG. 2 is a schematic longitudinal sectional view of the secondary carbonizing device 30 shown in FIG. The coarse carbide generated by the primary carbonization device 10 is transferred to the carbide container 34 and is put into the secondary carbonization device 30 as it is. Since the high-temperature gas is fed into the secondary carbonizing device 30 from the gas processing device 20 through the high-temperature gas inlet 32, the secondary carbonizing device is filled with the high-temperature gas of about 700 to 900 ° C. As a result, the volatile component contained in the crude carbide in the carbide container is removed by the heat of the high-temperature gas, and a high-quality carbide is generated.

Here, the carbide container 34 is not always necessary in the present invention, but it is preferable to use the container because it is possible to easily produce high-quality carbide. That is, in the present invention, it is necessary to feed the crude carbide generated in the primary carbonization device to the secondary carbonization device. Here, in the case where the carbide container 34 that can be taken in and out of the secondary carbonization device is installed,
First, the carbide container 34 is taken out of the secondary carbonization device, and this container 34 can be used as a container to be used when removing the coarse carbide from the primary carbonization device. It is because it becomes possible to obtain a high-quality carbide by re-entering the inside.

Therefore, the shape and size of the carbide container are not particularly limited because it is used for convenience in handling carbide. For example, handles may be provided on both sides of the container for easy carrying. Since the carbide container is only required to have a simple shape as a container, it is often exposed to a high temperature state, but this is not a major problem in terms of cost.

Further, the present invention does not particularly limit the position, installation method, and the like when installing the carbide container in the secondary carbonization apparatus. In particular, since it is preferable to uniformly heat the coarse carbide in the carbide container, a support 35 is provided in the apparatus as shown in FIG.
It is preferable to install a container on 5.

The carbide container preferably has a lid 36. This is because having the cover 36 can prevent impurities such as dust from being mixed when transferring the carbide from the primary carbonizing device to the secondary carbonizing device.
In this case, the lid 36 has an exhaust pipe 37.
Is preferably provided, and its shape is preferably an inverted J-shape. This is because, by forming the exhaust pipe 37 into an inverted J-shape, falling objects (for example, rain and dust) can be prevented from entering the carbide container.

Next, the exhaust port 33 of the secondary carbonizing device will be described. The exhaust port 33 is used for exhausting the high-temperature gas used in the secondary carbonization device, and its shape is not particularly limited in the present invention.

Further, in the present invention, as shown in FIG. 3, the exhaust port 33 provided in the secondary carbonizing device can be directly connected to the heating chamber of the primary carbonizing device by the pipe H3. By doing so, the high-temperature gas used for producing good-quality carbide in the secondary carbonization device can be reused when carbonizing a new processing target in the primary carbonization device. Because.

In the present invention, the temperature of the gas discharged from the secondary carbonization device through the exhaust pipe is 300 to 400 ° C., and the temperature is substantially the same as the temperature at which the target object is carbonized in the primary carbonization device. Therefore, it can be used in the primary carbonization apparatus without any treatment, which is effective as a whole. Note that the above-described respective devices (primary carbonizing device, gas processing device, and secondary carbonizing device) can also be used in the carbonizing device shown in FIG.

The present invention is not limited to the above embodiment. The above embodiment is an exemplification, and any one having substantially the same configuration as the technical idea described in the claims of the present invention and having the same function and effect can be obtained. It is included in the technical scope of the present invention.

For example, in the above-described embodiment, the primary carbonizing device, the gas treatment device, and the secondary carbonizing device are separated from each other and connected to each other by pipes. However, in the present invention, it is not always necessary to separate them. Instead, the respective devices may directly communicate with each other. Since each device is in direct communication, heat loss can be reduced when high-temperature gas or the like moves in the pipe.

[0053]

By providing a secondary carbonization device in addition to a primary carbonization device and a gas treatment device, it is possible to easily and inexpensively produce high-quality carbide compared to a carbide produced in a conventional carbonization device. The gas generated in the primary carbonization device can also be used effectively.
