DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an organic material continuous carbonization apparatus for drying and carbonizing organic material such as sewage sludge, food processing waste, sludge of a paper mill or livestock dung.

[0002]

2. Description of the Related Art As this type of continuous carbonizing apparatus, a 300
There is one described in Japanese Utility Model Registration No. 9966.
In this apparatus, a semi-cylindrical transport path and a cylindrical transport path for transporting organic raw materials such as livestock dung are arranged in a rectangular cylindrical furnace having a combustion chamber at the bottom. The organic material is dried and carbonized by heat generated in the combustion chamber while the organic material is being conveyed by the passage.

[0003]

However, in the above-mentioned conventional apparatus, when an organic material having a high water content exceeding about 60 to 70%, such as sewage sludge, is supplied to the apparatus, the raw material is not supplied. Adheres to the inner wall of the transport path or the screw, thereby closing the transport path, and a phenomenon occurs in which the organic material cannot be transported. In addition, when the conveyance becomes impossible, maintenance work such as cleaning accompanied by disassembly of the conveyance path is required, so that there is a disadvantage that the operation efficiency is lowered and the cost is increased.

Further, as the organic raw material is conveyed from the upper conveying path to the lower conveying path, its water content evaporates. However, the combustion chamber is disposed at the bottom of the rectangular tubular furnace body. As a result, the heating efficiency of the organic material that is conveyed through the upper conveying path and therefore contains a large amount of water is low, and the water contained therein cannot be efficiently evaporated. In addition, it takes time to raise the temperature inside the rectangular cylindrical furnace to the set temperature, and it takes time to start up the apparatus.

Further, utilizing the heat generated in the combustion chamber,
Since the organic raw material is merely dried and carbonized, the organic raw material, which is already chemically adsorbed with impurities and cannot be activated, cannot be activated, and its use is limited.

The apparatus for continuously carbonizing an organic material according to the present invention can satisfactorily transport the organic material regardless of the water content of the organic material, and can efficiently evaporate the water content of the organic material. It is intended to be activated.
