処理が難しいといった問題が存在する。2. Description of the Related Art At present, relatively advanced methods of treating medical waste and hazardous business waste include incineration treatment using first and second combustion chambers and incineration treatment using a fluidized bed furnace. Or high temperature processing using plasma. Among them, the method using plasma requires high equipment cost and can achieve a high temperature due to the influence of the range of use of plasma, but it is difficult to perform a uniform treatment. In addition, the cost of the incineration process itself is high, and resource recovery cannot be completely achieved. Incineration treatment using a fluidized bed furnace can treat oily sludge and wastes that are difficult to mix with air, but cannot perform thermal decomposition under conditions in which oxygen is cut off. In addition, since complete combustion is not possible, the destruction and removal rate for harmful substances is too low, and harmful substances cannot be clearly treated because combustion and thermal decomposition occur simultaneously during incineration of waste. In addition, a large amount of gas having a composition that causes harmful air pollution is generated, and the concentration is high. For this reason, equipment for treating air pollution is required, which increases the cost of the equipment and the running cost. When treating medical waste by incineration using the first and second combustion chambers, combustion and thermal decomposition also occur simultaneously in the first combustion chamber. For this reason, a large amount of a composition serving as a harmful pollution source after the combustion treatment is performed by the second combustion chamber is generated. The concentration is also high. Therefore, there is a problem that subsequent processing is difficult.

The waste in the inner cylinder (80) is heated indirectly. The combustion exhaust gas after heating is supplied to an exhaust valve (gh , e).
(1) After flowing out from) and being collected through a discharge pipe (4), the collected water enters a washing tower (91) to remove harmful substances by extraction and filtration. In this case, the liquid harmful substances are neutralized in the acid / alkali neutralization tank (9), and the gas is guided to the chimney (93) by the ventilation fan (92) and discharged. The contaminated air equipment from the washing tower (91) to the chimney (93) is provided by applying a conventional technique. However, the exhaust gas composition measuring equipment measures the gas emitted from the chimney over a 24-hour period, and measures the quantity and concentration of the constituent components of the exhaust gas emitted. For this reason, it is possible to know the relationship between the components of the harmful substances serving as the main air pollution sources and the operating conditions of the pyrolysis furnace and the second combustion chamber. Also, it can be demonstrated that the composition of the pollutant contained in the exhaust gas emitted by the system of the present invention has the lowest concentration.
