【考案の詳細な説明】
本考案は下水汚泥、し尿汚泥などの有機性廃棄
物の焼却に好適な回転式焼却炉（ロータリーキル
ン）に関するものである。[Detailed Description of the Invention] The present invention relates to a rotary incinerator (rotary kiln) suitable for incinerating organic wastes such as sewage sludge and human waste sludge.
従来例えば下水汚泥、し尿汚泥などは最終的に
焼却処理されるのが一般であり、そのための装置
として回転式焼却炉が多用されている。 Conventionally, for example, sewage sludge, human waste sludge, and the like have generally been finally incinerated, and rotary incinerators have often been used as equipment for this purpose.

し後者では臭気分は焼却炉内で燃焼される利点が
あるものの省エネルギー的な焼却処理が困難であ
るなど、前者と裏返しの長所・欠点がある。 There are two types of rotary incinerators, the so-called counter-current type and the co-current type.The former uses the heat of the combustion exhaust gas to dry the sludge, which has the advantage of reducing auxiliary energy consumption in the incinerator. On the other hand, the exhaust gas outlet temperature decreases (generally 150 to 250
°C) and the odor components are not decomposed and are emitted together with the exhaust gas, which poses problems in odor treatment. On the other hand, although the latter has the advantage that the odor components are burned in an incinerator, it is difficult to incinerate in an energy-saving manner, and has the same advantages and disadvantages as the former.

構成が複雑となる問題点がある。 Therefore, methods for treating high concentration odors generated from organic waste include (1) direct combustion (deodorization) method; (2)
There are catalytic combustion (deodorizing) methods, (3) chemical cleaning (deodorizing) methods, etc., but although chemical cleaning methods have the advantage of low running costs, their deodorizing effects are low, and they are particularly difficult to treat odors with a burnt smell. It is said that it is not suitable. The direct combustion method and catalytic combustion method are excellent methods for completely removing odors, but the direct combustion method has high running costs because it is necessary to constantly maintain the reaction temperature at 800-850℃ and the residence time at 1 second or more. There is a drawback. The catalytic combustion method has a low reaction temperature of 350 to 400 degrees Celsius, but it requires energy to raise the temperature of the odor gas to 350 to 400 degrees Celsius, and also requires a mechanism to remove dust attached to the catalyst surface. There is a problem that the configuration is complicated.

The purpose is to

The inner cylinder has a double structure so that the outer cylinder and the inner cylinder can rotate together, and the space between the outer cylinder and the inner cylinder is filled with a granular deodorizing metal catalyst to form a catalyst layer.

Proceed to. In other words, most of the odorous gases mainly composed of hydrocarbon compounds and sulfides are converted into relatively odorless gases such as H 2 O, CO 2 , and SO 2 through the catalytic action, and then deodorized gases are used.

Most of the dust generated during the combustion process is discharged to the outside through the rotary valve 23 and the electrostatic precipitator 13, and a small portion flows into the catalyst layer 5 together with the exhaust gas and adheres to the metal catalyst surface. Due to the movement of the catalyst particles due to the rotation of the
The pressure drop remains constant at all times, so there is no need to worry about blockages.

The deodorizing performance is maintained at a high level, and the problems of conventional countercurrent incinerators, which require a separate odor gas treatment device, are definitely solved, and the By using dissipated heat as a deodorizing heat source, it is possible to obtain a deodorizing effect in an extremely energy-saving manner, making it possible to incinerate sludge, etc. in densely populated areas, and the device structure is simple and compact, making it easy to install. It has practical effects such as being able to reduce the area, easy to operate and maintain, and greatly contributing to improving the efficiency of human waste collection in local governments.

A rotary incinerator that incinerates materials to be incinerated by bringing them into contact with combustion air in a countercurrent manner, in which the main body of the incinerator is provided with an outer cylinder and concentrically with the outer cylinder. The inner cylinder has a double structure made of metal plates, allowing the outer cylinder and inner cylinder to rotate as a unit, and the space between the outer cylinder and the inner cylinder is filled with granular deodorizing metal catalyst to form a catalyst layer. An incinerator further characterized in that the combustion exhaust gas outlet of the inner cylinder and the catalyst layer are communicated via a flow path. 2. The incinerator according to claim 1, wherein the inner cylinder is constructed using a heat-resistant steel plate as the metal plate. 3. The incinerator according to claim 2, wherein the portion of the inner cylinder that forms the catalyst layer is provided with metal fins protruding toward the outer cylinder. 4. Utility model registration claim 2, wherein the inner cylinder is provided with a metal tube in the catalyst layer, the axially both end portions of which are spaced apart in the axial direction of the inner cylinder and communicate with the inside of the inner cylinder. The incinerator mentioned. 5. The incinerator according to claim 2, 3, or 4, wherein the catalyst layer is formed by filling a metal catalyst supported on alumina. 6 Utility model registration claims 2, 3, 4, or 5, wherein the outer cylinder is a metal perforated plate having vent holes smaller in diameter than the metal catalyst.
Incinerator described in section. 7. The flow path communicating the combustion exhaust gas outlet and the catalyst layer is equipped with an electrostatic precipitator, an indirect cooling type cooling device, a desulfurization device, and an induction fan in order along the flow direction of the combustion exhaust gas. Certain utility model registration claims paragraphs 2, 3, and 4,
The incinerator described in paragraph 5 or 6. 8. A claim for utility model registration in which the catalyst layer is provided with an inlet for the combustion exhaust gas to be deodorized on the combustion exhaust gas outlet side and an outlet for the deodorized gas on the combustion air supply side. The incinerator according to the range 2, 3, 4, 5, 6 or 7.
