Description

The present invention relates to a combustion apparatus for burning various wastes.

In recent years, with the development of modern civilization and the diversification of lifestyles, environmental pollution is becoming more serious day by day, and environmental problems such as global warming and destruction of ecosystems are attracting attention. The United Nations, government agencies, and environmental groups around the world have set various goals for environmental protection and are actively conducting research to solve the problems. Also, private companies are actively developing technologies to solve these problems.

However, until now, incineration and landfill disposal have been the main means of disposing of various types of waste. They are being dumped or left unattended, and the problem of environmental pollution is becoming more serious.

In addition, the problem of disposal of various kinds of waste such as household waste, industrial waste, medical waste, etc. is not only a problem of specific countries and regions such as developing countries, but also a problem of all humankind, and is an important issue. It is also an issue.

On the other hand, the incineration method at waste incineration plants, which many countries, especially developed countries, rely on, incurs high initial installation costs, as well as costs for collection, separation, transportation, incineration, and facility operation. There are problems such as In addition, in the landfill disposal method of waste, a wide site for landfilling waste is required one after another. Furthermore, the landfill method also has the problem of causing secondary environmental pollution such as soil contamination and water contamination.

In order to solve these problems, some developed countries have proposed many technologies related to small-sized incinerators using organic matter treatment and high-temperature/low-temperature pyrolysis technology. However, these small incinerators have problems such as the amount of waste that can be processed is limited and the processing of non-combustible waste is difficult. It is also difficult to remove soot, dust, odors, etc., and there are many issues for practical use.

On the other hand, various related studies are being conducted in developed countries including Japan for the incineration of waste. "Small incinerator" described, "High-temperature pyrolysis incinerator" described in Korean Patent No. 10-1483751, and "Environment-friendly incinerator for waste disposal" described in Korean Patent No. 10-1602597 etc., have been proposed.

Japanese Patent Application Laid-Open No. 2002-71116 discloses an incinerator having a decomposition section, a dust collection section, an electric heater, a decomposition catalyst section, etc. on the upper side of a combustion chamber. However, with this device, it is difficult to maintain a high temperature inside the incinerator, making it difficult to treat waste with a high moisture content, and it is necessary to prevent the emission of harmful gases generated by incomplete combustion. There is

In addition, Japanese Patent No. 4093468 describes a small incinerator equipped with an air nozzle for treating combustion gas on the upper side of a combustion chamber consisting of a main combustion chamber and a recombustion chamber. A configuration is disclosed in which a cooling water spray nozzle is provided for this purpose. However, such a small incinerator has a problem that it is not easy to dispose of organic waste with a high water content.

In addition, in Korean Patent No. 10-1483751, it is configured to forcibly blow outside air through the air injection port of the blower pipe installed in the combustion chamber, and to completely burn the incinerated material at high temperature. A high-temperature pyrolysis incinerator is disclosed that can prevent incomplete combustion of the incinerated material by increasing the number of combustion layers. However, in this device, the opening and closing part is provided on the upper side of the combustion part, and there is a danger of fire due to the high temperature combustion gas discharged from the upper part. It is not easy, and there is a possibility that incomplete combustion of organic wastes and wastes with high moisture content may occur due to the close contact in the lower part of the combustion chamber.

In addition, Korean Registered Patent No. 10-1602597 discloses an environment-friendly incinerator for waste disposal, which is configured to reburn combustion gas generated by burning waste and enables complete combustion. However, the configuration of the high-temperature combustion chamber required for waste treatment and the configuration for removing harmful gases are not disclosed.

A mouth 102 is formed. In addition, the combustion chamber 100 has an inner wall formed with a layer composed of a high-concentration ceramic or castable refractory that is excellent in heat resistance and acid resistance and capable of generating radiant heat.
