Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0002]

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.

And the discharge pipe (4) are connected in parallel. Therefore, each of the pyrolysis furnaces can be individually operated and controlled. The individual operation of each pyrolysis furnace is disclosed below. That is, each valve connected to the pyrolysis furnace (81) is closed, and the inner tube (80) for pyrolysis of the pyrolysis furnace (81) is taken out and filled in the inner tube (80) for pyrolysis. Then, an appropriate amount of waste to be treated is loaded into the pyrolysis furnace, the furnace is closed, the extraction valve (P ₁ ) is opened, and the vacuum pump 71 is started to activate the pyrolysis furnace (81). A gas is extracted from the inside of the internal cylinder (80) to make a vacuum state. Ki extracted After extracting from the inner tube for thermal decomposition (80) to make a vacuum, the extraction valve (P ₁ ⁽¹⁾ ) is closed and the recovery valve (g _c ⁽¹⁾ ) is opened. In this case, the collection valve (g

Further, steam is removed from the pyrolysis gas that is not distilled (so-called gas) to achieve complete combustion in the second combustion chamber (7). The liquid combustion oil and liquid water are separated by an oil / water separator and recovered respectively. Finally, the gas enters the second combustion chamber (7) via the recovery pipe (5) and is burned. In the second combustion chamber (7), the quality of the entering liquid fuel oil and air The combustion temperature of the second combustion chamber (7) is controlled within the range having a high destructive removal rate for the quality, and based on the data of the composition and concentration of the released gas measured by the waste composition measuring equipment (94).

Next, after the thermal decomposition of the treated waste was completed in the thermal cracking internal chassis (80), closing the respective valves to be connected to the pyrolysis furnace before extraction valve (P ₁
⁽¹⁾ Only) is opened, the gas generated by the pyrolysis remaining in the inner tube for pyrolysis (80) is passed through the cooling heat exchanger (72), and is again sucked by the vacuum pump (71). The gas flows into the second combustion chamber (7) via the recovery pipe (5) and is burned. After a predetermined time, the extraction valve (P 1 ^₍₁₎₎ to close the opening the intake valve (a 2 ^_(1)), advancing the fresh cold air to the internal chassis pyrolysis (80) the . After the cold air is filled, the extraction valve (P ₁
⁽¹⁾ ) is opened and the intake valve (a ₂ ⁽¹⁾ ) is closed. Then, after extracting the air again to make a vacuum,
Close the extraction valve (P ₁ ⁽¹⁾ ) (this step is for cooling the inner cylinder for pyrolysis, but the gas generated by the pyrolysis is not released directly into the air. ), The heating chamber formed by the outer layer (C1) of the pyrolysis furnace (81) is opened, and another inner cylinder for pyrolysis (80) filled with waste is newly charged into the heating chamber to perform pyrolysis. . The thermal decomposition work is performed by circulating in this manner. In addition, the same applies to the steps related to the pyrolysis operation of the pyrolysis furnace.
