は実現されていない。BACKGROUND ART In recent years, with the development of industrial technology, a large amount of industrial waste of various types has been discharged, and incineration is being performed as one of the disposal methods. However, depending on the type of waste, it often has a high calorific value and is difficult to burn completely, emitting a large amount of soot or smoke, or generating a bad odor or toxic gas, resulting in secondary pollution. Therefore, various incinerators for industrial waste have been developed, but a furnace that can perform satisfactory combustion has not yet been realized.

We have developed a combustion device that supplies air from the top of the furnace during combustion. Although this combustion device showed a considerably superior combustion effect compared to conventional combustion devices, it was still not able to sufficiently prevent the emission of soot and toxic gases.

問題点を解決して本発明を完成した。[Means and effects of the invention for solving the problems] As a result of further research, the present inventor found that in a hearthless combustion device consisting of a heat-resistant concrete furnace wall buried in the soil, there is no combustion material on the furnace ceiling. A first combustion chamber having a material input port and an air supply port, a second combustion chamber having an air supply port on the furnace ceiling and arranged above the first combustion chamber, and a second combustion chamber having an air supply port on the furnace ceiling; The present invention has been completed by solving the above problems with a combustion apparatus having a dust collection chamber for guiding combustion waste gas to a chimney and collecting dust in the combustion waste gas.

んどない。The combustion device of the present invention will be explained with reference to the drawings. FIG. 1 is a longitudinal cross-sectional view of the combustion apparatus of the present invention, in which 1 is the furnace side wall made of heat-resistant concrete, 2 is the exposed bottom of the furnace, and 3 is the furnace ceiling made of heat-resistant concrete, the surface of which has been reinforced. When using this combustion device to burn the chip-shaped crushed material of old and damaged fiber-reinforced plastic (FRP) mate, K first opens the furnace lid 5 and connects the first combustion chamber 7 to the approximately second combustion chamber. F until you reach the bottom height of 8
The RP chip is put in, the top thereof is covered with wood chips for ignition, the wood chips are ignited, the furnace lid is closed, and only the air supply port 61 is opened to feed air into the first combustion chamber. When the ignition of the FRP chip is confirmed and its combustion begins, the air supply port 62 is also opened to increase the amount of air 3' supplied to the first combustion chamber. The combustion of the chips progresses gradually from right to left in FIG. 1, and at the same time from top to bottom. Note that it is preferable to arrange an appropriate number of air supply ports to adjust the amount of air supplied. As combustion progresses, the air supply port 63 is also opened appropriately to promote combustion. As the combustion gradually becomes more intense, a wave-like air current is generated in the first combustion chamber, and the chips are gradually incinerated from the surface layer to the core. When this situation is reached, the air supply port 64 of the second combustion chamber is opened. The combustible gas that was not completely combusted in the first combustion chamber is then almost completely combusted in the second combustion chamber 8. The combustion gas coming out of the second combustion chamber enters the cylindrical dust collection chamber 9 having the shape of a cyclone from the tangential direction, where it is subjected to the action of the cyclone and a small amount of the dust contained therein is removed. Unburned materials are collected and accumulate at the bottom of the dust collection chamber. The waste gas after dust collection is almost completely combusted and released into the atmosphere from the chimney 4, but there is almost no odor and there is very little soot, so there is little risk of environmental pollution. do not have.

ある。The materials to be combusted are put into the combustion device of the present invention in a patch manner, and the next combustion operation is started after one combustion process is completed. It is sufficient to remove the ash after completing several dozen incineration operations, and it is sufficient to remove dust from the dust collection chamber once a year.

発生も殆んどない。Although the combustion mechanism of the combustion apparatus according to the present invention is not fully understood yet, as the combustion progresses in the first combustion chamber and the temperature inside the furnace rises, moisture in the soil flows from the exposed top forming the bottom of the furnace. One of the major factors is thought to be that H2 and CO are induced into the combustion chamber and H2 and CO are generated by a water gas reaction, thereby promoting combustion within the first combustion chamber. The moisture extracted from the bottom of the furnace is constantly replenished from the surrounding soil during combustion, and once combustion begins, it is extremely stable and complete. Also, the air flow inside the combustion chamber is very slow compared to the case of a combustion device using a normal grate.
Because of this, there is little soot and dust being kicked up from the materials to be burned, and there is almost no fly ash generated.

臭を有していない。According to the combustion device of the present invention, the combustible gas that has not been completely burned in the first combustion chamber is stored in the second combustion chamber at approximately 120 m
When the combustion gas meets the dust collection chamber, there is almost no unburned material, but since the temperature inside the dust collection chamber is still high, it is burned in the second combustion chamber. The small amount of combustible gas that is not combusted will not be completely combusted within the dust collection chamber. Therefore, the waste gas released into the atmosphere from the chimney has almost no odor.
