[0001]

The present invention relates to a carbonization apparatus,
In particular, the present invention relates to a carbonization apparatus provided with a carbonization chamber for carbonizing an object to be treated such as garbage and a combustion chamber for burning and decomposing harmful substances such as dioxin generated at the time of carbonization at a high temperature.

[0002]

2. Description of the Related Art In general, water and air are purified or soil is improved by using a charcoal produced by dry distillation of a piece of wood or the like.

[0003] In a conventional carbonization apparatus, propane gas or bincho charcoal is used as a heating source, and gas or the like generated during carbonization processing is directly discharged from a chimney to an external space.

[0004]

As described above, in the conventional carbonization apparatus using propane gas or Bincho charcoal, the carbonization after the carbonization treatment has a high water content of, for example, 10% or more, so that the utility as carbon is low. There was a problem. This is remarkable in garbage and the like having a high water content.

When Bincho charcoal is used, since Bincho charcoal is porous and its temperature distribution during heating is not uniform, it takes 2 to 3 hours for the carbonization chamber to reach a desired temperature. There was such a problem.

[0006] Further, there is a problem in that the treatment of gas (dioxin) and odor generated at the time of carbonization is inadequate, which impairs the health of workers and nearby residents and deteriorates the environment in the surrounding area.

Therefore, according to the present invention, by providing a combustion chamber for removing harmful substances such as dioxin on the downstream side of the carbonization chamber, so-called, and using a ceramic heater as a heating source for each of the carbonization chamber and the combustion chamber, The time required for each of these chambers to rise to the predetermined processing temperature at the start of operation is shortened, and garbage, etc., also produces low-moisture-content carbides. ・ Emission of harmful gases and odors generated during carbonization to the outside It aims at suppressing.

[0008]

The present invention solves this problem as follows. (1) A carbonization chamber for carbonizing an object to be treated, a combustion chamber into which a harmful gas generated in the carbonization chamber flows through a communication portion, and a first internal space of the carbonization chamber suitable for carbonization processing. A first ceramic heater for setting a temperature, and a second ceramic heater for setting the internal space of the combustion chamber to a second temperature higher than the first temperature and suitable for dioxin treatment. Prepare. (2) In the above (1), a porous gas diffusion member is provided on the inflow side of the combustion chamber. (3) In the above (1) or (2), a conduit for sending a high-temperature gas generated in the combustion chamber to a space in contact with an outer surface of the carbonization chamber is provided.

According to the present invention, as described in (1) above, the object to be treated is carbonized by carbonization by the first ceramic heater in the carbonization chamber. The gas containing odorous substances such as foul odors and dioxins which flows into the combustion chamber via the communicating part, is decomposed by high-temperature combustion by the action of the second ceramic heater.

[0010] Since the carbonization chamber and the combustion chamber are heated by the ceramic heater, the rise time of the carbonization apparatus is shortened, and the carbonized garbage has a low moisture content.

Further, as described in (2) above, the gas containing harmful substances generated in the dry distillation chamber passes through the porous gas diffusion member and is in a state of being dispersed on average, so that the gas is efficiently stored in the combustion chamber. Burn.

Further, as in the above (3), since the high-temperature gas generated in the combustion chamber is sent to the space in contact with the outer surface of the carbonization chamber, the interior of the carbonization chamber is not only the first ceramic heater but also the outer surface of the carbonization chamber. Is also heated.
