Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waste treatment apparatus equipped with a catalyst for incinerating waste and purifying the exhaust gas thereof.

[0002]

2. Description of the Related Art Conventionally, a waste treatment apparatus of this type is shown in FIG.
There was a configuration as shown in.

The structure will be described below with reference to the drawings. As shown in the figure, a heat insulating furnace material 3 is stretched around the inner surface of a combustion furnace 2 having a lid 1 that can be opened and closed,
An exhaust port 4 communicating with the outside is provided on the wall surface, and a purifier 5 is connected to the downstream side of the exhaust port 4. A furnace heater 6 is fixed to an inner bottom portion of the combustion furnace 2 so that a tip of the furnace heater 6 projects inward, and a terminal portion of the furnace heater 6 projects to the outside of the combustion furnace 2. Inside the combustion furnace 2, a metal processing container 7
Is provided, the furnace heater 6 is included in the bottom surface of the processing container 7, and a cylindrical portion 9 having an opening 8 is formed on the wall surface thereof. Further, in the purifier 5, a catalyst body 10 and a purification heater 11 for heating the catalyst body 10 are arranged. Further, an air supply port 12 is provided on the bottom surface of the combustion furnace 2, and an air supply device 13 is used to allow air to flow from the tubular portion 9 into the processing container 7. In the figure, 14 is a waste.

In the above structure, the lid 1 is opened and the waste 1
When the furnace heater 6 is energized after charging 4 and closing the lid 1, the waste 14 is heated and incinerated by thermal energy,
The generated exhaust gas is purified by the purifier 5 and discharged. This operation is controlled by a preset time set by a program timer according to the amount of waste. That is, first, the purifier 5 and the air supply device 13 are operated to bring the purifier 5 into a sufficiently functional state, and then the furnace heater 6 is operated, and after a set time, the operations of the furnace heater 6 and the purifier 5 are stopped. Finish the incineration process. Then, after blowing and cooling the combustion furnace 2, the air supply device 13 is stopped.

[0005]

However, in the above-mentioned conventional structure, the waste 14 to be incinerated has a large amount of heat generation that contains a large amount of oil, and in this case, combustion becomes abnormally intense and oxygen deficiency occurs. Since a large amount of soot is generated due to incomplete combustion, the catalyst body 10 is clogged, deteriorates, and the purification performance deteriorates. As a result, there has been a problem that unpurified exhaust gas is emitted to give off a bad odor to the surroundings.
Further, although the catalyst body 10 is taken out from the purifier 5 when performing maintenance, this operation is not easy and
However, there is a problem that the purification performance is deteriorated due to variations in disassembly and assembly.

The present invention solves the above-mentioned conventional problems. When the catalytic body in the purifier loses its function, the catalytic body can be easily maintained without deterioration of the purification performance. The purpose is to provide a device.

[0007]

In order to achieve the above object, the present invention provides a combustion furnace having an openable / closable lid, an air supply port and an exhaust port, and a furnace provided so as to project from the inner bottom of the combustion furnace. A heater, an air supply device connected to the air supply port, a purifier having a partition plate connected to the exhaust port, and a catalyst body arranged inside the purifier to purify the exhaust gas. The catalyst body is fixed to the partition plate via the receiving plate.

[0008]

In the above structure, when the catalyst body is deteriorated by the exhaust gas, the purifier lid can be removed, the catalyst body can be taken out together with the receiving plate, and after maintenance, the catalyst body can be incorporated into the purifier again. The purifier can be maintained without degrading its performance.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In this example,
The same components as those shown in the above-mentioned conventional example are designated by the same reference numerals, and the description thereof will be omitted. The characteristic configuration of this embodiment is that the catalyst body 10 described in the conventional example can be attached to and detached from the purifier 15. That is, the purifier 15 is composed of a purifier exterior 15a and a purifier lid 15b, a partition plate 16 is provided inside the purifier exterior 15a, and the partition plate 16 has an opening 16a. The catalyst body 10 is fixed to the receiving plate 17 and is provided in close contact with the upper portion of the partition plate 16. There is a clearance between the catalyst body 10 and the purifier exterior 15a, and the inner diameter of the opening 16a is the receiving plate 17
Smaller than the outer diameter of.

In the above structure, the lid 1 is opened and the waste 14
When the furnace heater 6 is energized after charging, the waste 14 is heated by thermal energy, and is heated and incinerated by the combustion air supplied from the air supply device 13. The exhaust gas generated during this combustion enters the purifier 15 through the exhaust port 4, passes through the opening 16a of the partition plate 16, and opens in the opening 17 of the receiving plate 17.
It is guided to the catalyst body 10 from a, is smokeless and deodorized, and is discharged to the outside.

At this time, when a large amount of soot is generated due to incomplete combustion to cause clogging of the catalyst body 10 or deterioration progresses and maintenance is required, the purifier lid 15b is opened and the receiving plate 17 is opened. At the same time, the catalyst body 10 is removed and cleaned or replaced.

As described above, according to the waste treatment apparatus of the embodiment, since the partition plate 16 is provided in the purifier 15 and the catalyst body 10 is fixed to the partition plate 16 via the receiving plate 17, the catalyst body is fixed. Even if 10 is deteriorated by exhaust gas, purifier lid 15b
Since the catalyst body 10 can be taken out together with the receiving plate 17 after maintenance, and after maintenance, the catalyst body 10 can be incorporated into the purifier 15 again, the purifier 15 can be maintained without degrading the purification performance. .

[0013]

As is apparent from the above embodiments, in the waste treatment apparatus of the present invention, the catalyst body is fixed to the partition plate in the purifier through the receiving plate, and this structure is adopted. Thus, when the catalytic body in the purifier loses its function, the catalytic body can be easily maintained without deteriorating the purifying performance, and the practical value is remarkable.
