There is a problem such as In addition, the waste landfill treatment method requires a large amount of land for landfilling waste one after another. Further, the landfill treatment method has a problem that secondary environmental pollution such as soil pollution and water pollution occurs.

In order to solve these problems, in some developed countries, many technologies related to small incinerators using organic matter treatment and high-temperature / low-temperature pyrolysis technology have been proposed. However, these small incinerators have problems such as a limited amount of waste treatment and difficulty in treatment of non-combustible waste, so that only selective treatment is possible, and they are generated at the time of incineration. It is also difficult to remove soot, dust, and odors, and there are many problems in putting it into practical use.

On the other hand, various related studies are being conducted in developed countries including Japan for the incineration treatment of waste. For example, "Incinerator" described in JP-A-2002-71116 and Japanese Patent No. 4093468 are being conducted. "Small incinerator" described, "High temperature thermal decomposition incinerator" described in Korean Registered Patent No. 10-1483751 and "Friendly environment incinerator for waste treatment" described in Korean Registered Patent No. 10-1602597. Etc. have been proposed.

Japanese Unexamined Patent Publication No. 2002-71116 discloses an incinerator provided with a decomposition unit, a dust collector, an electric heater, a decomposition catalyst unit, and the like on the upper side of the combustion chamber. However, with this device, it is difficult to maintain the high temperature inside the incinerator, it is difficult to dispose of waste with a high water content, and it is necessary to prevent the emission of harmful gas generated by incomplete combustion. There is.

Further, in Japanese Patent No. 4093468, the temperature of combustion gas is lowered in a small incinerator provided with an air nozzle for treating combustion gas on the upper side of a combustion chamber composed of a main combustion chamber and a recombustion chamber. Therefore, a configuration provided with a cooling water spray nozzle is disclosed. However, the small incinerator has a problem that it is not easy to treat organic waste having a high water content.

Further, the Korean Registered Patent No. 10-1483751 is configured to forcibly blow external air through the air injection port of the blower pipe installed in the combustion chamber, and completely burns the incinerated product at a high temperature. A high-temperature thermal decomposition incinerator capable of preventing incomplete combustion of an incinerated product by forming multiple layers of combustion layers is disclosed. However, in this device, an opening / closing part is provided on the upper side of the combustion part, and there is a risk of fire due to the high temperature combustion gas discharged from the upper part, and dust generated at the time of throwing in waste can be removed. It is not easy, and incomplete combustion of organic waste and waste with high water content may occur due to the close contact state at the bottom of the combustion chamber.

Further, in Korean Registered Patent No. 10-1602597, a friendly environment incinerator for waste treatment, which is configured to be able to reburn the combustion gas generated by burning waste and enables complete combustion, is disclosed. However, the configuration of the high temperature combustion chamber required for waste treatment and the configuration for removing harmful gas are not disclosed.
