Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waste disposal system for treating municipal solid waste, industrial waste or special waste containing unsorted and untreated materials of various materials and shapes by pyrolysis. And a thermal decomposition furnace apparatus.

[0002]

2. Description of the Related Art Conventionally, as a method of treating general waste or industrial waste, a method of thermally treating waste or the like which may be contaminated with harmful substances is known. This method is described in, for example, Japanese Patent Publication No. Hei 8-24904.

FIG. 12 shows a specific example of a thermal decomposition system used in this method. In the thermal decomposition processing system shown in FIG.
Through the charging device 52 into the pyrolysis furnace main body 53 and subjected to pyrolysis. The organic polymer gas generated by the thermal decomposition is reformed by the gas reformer 54 to become a low molecular flammable gas, purified by the gas purifier 55 and reused as a reformed gas as an energy source. You.

On the other hand, the residue generated in the pyrolysis furnace main body 53 is discharged out of the furnace from a residue discharging device 56, and further generates combustible gas in a gasification and melting furnace 57. The secondary substance discharged from the processing step is divided into a reformed gas that is reused as an energy source in the processing step and a slag discharged from the processing step. That is, in this system, it is possible to reuse the energy source in the form of a combustible gas called a reformed gas.

In such a thermal decomposition waste treatment apparatus, an externally heated rotary kiln for heating a rotary drum from the outside may be used as the thermal decomposition furnace main body 53, for example. FIG. 13 shows an example of a conventional pyrolysis furnace main body using an externally heated rotary kiln.

In the example shown in FIG. 13, waste (object to be treated) is
It is continuously or intermittently supplied from the waste input device 52 to the inside of the rotary drum 53a. The rotating drum 53a
It is supported at two points by rollers 53r and rotates at a low speed by a rotation drive mechanism 53b. The central portion of the drum 53a is disposed inside the combustion chamber 53c,
Is heated from the outside by the combustion gas of the burner 53d attached to the heater. The combustion exhaust gas is supplied to an exhaust gas duct 53.
e, it is discharged out of the combustion chamber 53c. The waste thermally decomposed by heating inside the rotating drum 53a is separated into a pyrolysis gas and a solid residue by a hood 53f at the outlet of the drum. At the connection between the rotating part and the stationary part,
A rotary seal device 53s is provided to partition the inside and outside of the drum. Further, the inside of the rotary drum 53a is usually set to a pressure lower than the atmospheric pressure so that harmful pyrolysis gas does not leak.

What is important when using such a pyrolysis furnace apparatus is to stably load an object to be processed into the furnace. Here, a specific example of the waste input device 52 will be described with reference to FIG.

[0008] In the example of FIG. 14, first, the hopper 5 above the main body cylinder 52 a of the waste input device 52
It is stacked for 2 hours and retained and kept at a certain height or higher so as to prevent unnecessary air from flowing into the furnace and leakage of pyrolysis gas. The waste is moved to the left side in the figure by the screw 52s and is thrown into the rotating drum 53a. The amount of waste introduced into the furnace is adjusted by the rotation speed of the screw 52s.

[0009]

The waste to be treated is a mixture of various kinds of substances and has various shapes. For this reason, particularly in the charging section, a closed state due to entanglement of the waste, a state in which the waste cannot be transported due to the formation of a bridge (bridge), and the like are likely to occur, which is a serious problem in the stable operation of the pyrolysis furnace.

Further, once blockage occurs in the charging section, the temperature of the body of the pyrolysis furnace must be lowered to perform repair work, and the apparatus must be stopped for a long time including reheating, and the operation rate of the apparatus must be reduced. Will decrease.

[0011] Further, the amount of air flowing into the pyrolysis furnace can be reduced.
Alternatively, in order to prevent the pyrolysis gas from flowing out due to the backflow, a so-called material seal in which waste is laminated is provided in the hopper. In order for this to work effectively, it is necessary to maintain the stack height of the waste at a certain height or higher, but the height of the waste is measured due to its irregular shape and unevenness. Difficult and very difficult to control. It has also been proposed to install a contact-type measurement sensor in the hopper, but this has led to the formation of entanglements and bridges in the waste, which hindered the stable input of waste into the furnace.

The present invention has been made in view of the above points, and it is possible to effectively prevent clogging of an object to be processed and always stably load the object into a furnace. An object of the present invention is to provide a pyrolysis furnace apparatus.

[0013]

According to the present invention, there is provided a first charging device into which an object to be processed is charged, a second charging device connected in series with the first charging device, and a second charging device connected to the second charging device. A first pyrolysis furnace main body, wherein the first charging device controls the amount charged to the second charging device while retaining the workpiece, and the second charging device includes the first charging device. The thermal decomposition furnace apparatus is characterized in that an object to be treated introduced from above is smoothly introduced into the thermal decomposition furnace.

According to the present invention, since the charging control and the charging into the furnace are functionally divided by the two-stage charging device, clogging of the workpiece at each charging device portion is effectively prevented. obtain. That is, compared with the conventional case where the stacking height is adjusted and the injection amount is controlled by one injection device, the inside of the injection device is filled with waste and compressed, and the effect of radiant heat from the pyrolysis furnace body side is added. The occurrence of blockage can be significantly reduced.

Further, according to the present invention, since the waste is charged into the pyrolysis furnace main body in a state where the waste is not filled in the second charging device in the latter stage, the waste is clogged. It is possible to perform stable input without any problem.

Preferably, a shutter mechanism is provided between the first input device and the second input device.

In this case, even if a blockage occurs in the first charging device portion or the like in the preceding stage, the shutter mechanism is closed so that the disassembly and inspection work of the first charging device portion can be performed without lowering the temperature of the pyrolysis furnace. It can be implemented. As a result, it is possible to greatly reduce the time during which the input of waste is stopped for maintenance, and to maintain a high operation rate.

[0018] Preferably, the first charging device is provided with a height sensor for detecting the staying height of the workpiece.

In this case, it is possible to easily control the stack height of the waste buildings, so that it is possible to more effectively prevent waste entanglement and bridge formation, and more stable disposal. It becomes possible to input things.
