Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention dry-distills (combusts) industrial waste such as waste tires, synthetic resins such as plastics, film materials, wood chips, wrapping paper materials, strings, waste paper, adhesives, or non-recyclable waste materials. ) The present invention relates to a dry distillation treatment apparatus for industrial waste, which is capable of treating and effectively using thermal energy of gas generated by the dry distillation (combustion).

[0002]

2. Description of the Related Art Conventionally, there is a dry distillation furnace in which industrial waste such as waste tires is self-combusted and the gas generated by combustion at that time is reused as thermal energy. FIG.
Is a conventional type carbonization furnace.
Waste such as a waste tire is put in the container, the lid 23 is hermetically closed, and the waste such as the waste tire is forcibly or self-combusted by the burner 21 for dry distillation (combustion) treatment. Then, the gas resulting from the combustion of the waste is sent from the exhaust port 22 to the boiler or the like.

[0003]

In the conventional type carbonization furnace, when the waste such as waste tires is carbonized in the carbonization furnace chamber, the wastes put in the furnace chamber are burned at once, and the combustion It becomes impossible to open the lid inside. Therefore, when the lid 23 of the furnace chamber 20 in operation is opened as shown in FIG. 13, an intense flame spreads over a wide area, and the surrounding area is extremely dangerous. For this reason, the work of opening the lid 23 of the furnace chamber 20 in operation and successively throwing in the waste has a risk that the worker is exposed to a flame due to combustion from the waste in the furnace chamber 20.

Therefore, until the combustion of the waste in the furnace chamber 20 is completed, there is the inconvenience that the lid 23 of the furnace chamber 20 cannot be opened and the next new waste cannot be thrown in. The processing of goods will be significantly delayed. In addition, the combustion of the waste in the furnace chamber gradually moves to the waste in the upper layer from the lower layer,
In many cases waste is not completely burned in practice,
The efficiency of the dry distillation (combustion) treatment work of the waste was reduced, and the reuse of the thermal energy of the gas generated by the dry distillation (combustion) treatment of the waste was often extremely inefficient.

[0005]

In order to solve the above-mentioned problems, the inventors of the present invention have made earnest studies, and as a result, according to the present invention, a bottom body is provided in the lower portion of the tubular wall body, and the above-mentioned tubular wall body is provided. A plurality of blower inflow holes only near the lower part of the, and a waste storage furnace that can be closed by providing an openable lid at the upper end of the tubular wall body;

The lower end of the pipe portion is fixed to the upper surface of the bottom plate, the upper end of the pipe portion communicates with the outside from the upper side of the tubular wall body, and the dry distillation gas externally provided with a plurality of gas inflow holes near the lower portion of the pipe portion. A dry distillation treatment device for industrial waste, which is composed of a supply pipe, and in which the cooling water can be circulated in the cylindrical wall body, the bottom body and the pipe portion, makes the dry distillation treatment of industrial waste more efficient. In addition, only the lower-layer waste is burned in the furnace, the upper-layer industrial waste is in a non-combustible state, and new waste can be safely input even during operation. It is a solution to the problem.
