TECHNICAL FIELD OF THE INVENTION
The present invention relates to a carbonization system that heats an object, extracts useful substances, and does not emit harmful substances to the outside to prevent environmental pollution.
[0002]
[Prior art]
BACKGROUND ART Conventionally, there is a carbonization system in which an object is subjected to a heat treatment to extract a useful substance.
[0003]
In this carbonization system, objects such as wood-based waste materials and wastes are subjected to heat treatment (pyrolysis) in a pyrolysis furnace, and the generated smoke is cooled and liquefied by a condenser (cooler). This distilled liquefied product is fractionated by a fractionation boiler and divided into a low boiling fraction, a wood vinegar solution, a high boiling fraction residue, and the like.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0012]
As shown in FIG. 1, the carbonization system of this embodiment heats (pyrolyzes) an object such as wood-based waste material and waste in a wood-based pyrolysis furnace, and converts a gas component such as generated wood smoke into a condenser. (Cooler) is liquefied. The number of capacitors may be set to one or two or more.
[0013]
The liquefied product in the condenser is heated and fractionated by a fractionating boiler and fractionated into low-boiling fractions, wood vinegar, and high-boiling fraction residues. A purified wood vinegar liquid is taken out from the wood vinegar liquid fraction, and thus useful substances such as charcoal and wood vinegar liquid can be obtained.
[0014]
Also, secondary contaminants (such as smoke from a burner burning heavy oil) generated during the combustion of fuel generated during the heat treatment in the wood-based pyrolysis furnace are cooled and liquefied by the condenser (1A in the figure). Smoke from burning fuel). Secondary contaminants generated during the combustion of the fuel during the heat treatment in the fractionation boiler are also cooled and liquefied by the condenser (see (1) in FIG. 1B).
[0015]
Unnecessary gas components generated by heating garbage in the accompanying garbage disposal plant (garbage composting plant, garbage carbonization plant, etc.) are also cooled and liquefied by the condenser (see FIG. 1). (1) Smoke during combustion of C fuel).
[0016]
On the other hand, fuel combustion residues during the heat treatment in the wood-based pyrolysis furnace (the fuel residue of A in FIG. 2) and fuel combustion residues during the heat treatment in the garbage treatment plant (FIG. 2) ▼ Fuel residue of B), fractionation boiler (fuel residue of C in Fig. 2) and condenser (solid residue during liquefaction in Fig. 3) are left in the incinerator. To incinerate completely at high temperatures.
[0017]
Also, components that cannot be recovered as useful substances are completely incinerated at a high temperature by the incinerator. Here, the gas components discharged when these are incinerated in an incinerator are guided to the condenser to be cooled and liquefied (such as the gas generated during combustion as shown in FIG. 4).
[0018]
Next, the use state of the carbonization system of this embodiment will be described.
[0019]
In this carbonization system, secondary contaminants generated during the heat treatment during the combustion of the fuel (smoke generated during the combustion of the fuel in FIG. 1A) are also cooled and liquefied by the condenser, and collected in a liquefied state. So that the pollutants do not have to be exhausted to the atmosphere. In other words, the secondary contaminants do not have to be liquefied and collected, and do not need to be exhausted to the atmosphere. Therefore, there is an advantage that substances that are harmful or possibly harmful to the external environment are not released as compared with the related art.
[0020]
In addition, secondary contaminants generated during the combustion of the fuel during the heat treatment in the fractionation boiler (smoke generated during the combustion of the fuel shown in (1) B) and gas generated by heating the accompanying garbage treatment plant The components (smoke generated during fuel combustion of C in FIG. 1) are also cooled and liquefied by the condenser, so that substances that are harmful or potentially harmful to the external environment are not released and garbage disposal is performed. There is an advantage that useful components can be taken out by cooling and liquefying gas components and the like generated in the plant.
[0021]
Further, the fuel combustion residue at the time of the heat treatment (the fuel combustion residue of A in FIG. 2) and the fuel combustion residue at the time of the heat treatment in the garbage processing plant (the fuel combustion residue of the B in FIG. 2) ), The residue remaining in the boiler for fractionation boiler (combustion residue of fuel in Fig. 2C) and the condenser (solid residue in liquefaction in Fig. 3) is completely incinerated at high temperature in an incinerator. Therefore, there is an advantage that it is more environmentally friendly than before.
[0022]
The components that cannot be recovered as useful substances are completely incinerated at high temperatures.Therefore, if the useful substances are removed and the finally unrecoverable residues are completely incinerated at high temperatures, the environment will be more environmentally friendly than before. It has the advantage of being easy.
[0023]
In addition, the gas components discharged during incineration in the incinerator are also cooled and liquefied by a condenser (such as the gas generated during combustion in FIG. 4), and the processable temperature is low due to the processing capacity of the incinerator. In particular, there is an advantage that by repeating these steps, secondary contaminants can be liquefied and harmful substances can not be emitted to the outside, especially when they can not completely burn and become harmless .
[0024]
In this way, the carbonization system has a closed system in the whole system, and has an excellent advantage that no harmful substances or potentially harmful substances are released to the outside.
[0025]
【The invention's effect】
The present invention is configured as described above and has the following effects.
[0026]
Since the secondary contaminants do not need to be liquefied and collected and exhausted to the atmosphere, it is possible to provide a carbonization system that does not emit harmful substances to the external environment as compared with the related art.
