Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a boiler for incinerating waste such as household garbage and excrement.

[0002]

2. Description of the Related Art An apparatus of this kind is disclosed in JP-T-Hei 2-50.
No. 0820, which is referred to as “incinerator toilet with catalyst container”. In this device, an annular electric heating coil is disposed above an ash pan for collecting waste, and when excrement is dropped into the ash pan through the center of the annular electric heating coil,
The annular electric heating coil generates heat, and the heat incinerates the excrement in the ashtray. The vaporized gas generated by the incineration is sucked into a catalyst provided along the outer periphery of the annular electric heating coil, and is discharged after the catalyst removes the odor.

[0003]

In the above-mentioned conventional apparatus, since an electric heating coil is used, power is naturally consumed. However, this electric power has a problem that the cost is high as compared with other gas and kerosene, so that the maintenance cost is increased.

[0004] In addition, although there are devices utilizing gas or kerosene, there has been no device which sufficiently considers deodorizing gas generated by incineration.

[0005] Therefore, an object of the present invention is to provide a boiler for incinerating filth that uses an inexpensive fuel such as gas or kerosene and has a sufficient capacity for deodorization.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a boiler for incinerating wastes according to the present invention has a substantially cylindrical shape.
A fuel combustion chamber is provided below the boiler
A vaporization chamber is provided above the boiler body, and the boiler body
An exhaust hole is provided at the upper end, and an incinerator is placed between the combustion chamber and the vaporization chamber.
There is a pan holder for the incinerator, and the outside diameter of the incinerator is
-Smaller than the inner diameter of the main body,
Plurality that passes through the gap between the outer circumference of the incinerator and the inner circumference of the boiler body
Are formed.

[0007]

According to this invention, the incinerator is placed on the pan holder above the combustion chamber, so that when the fuel is burned in the combustion chamber, the incinerator is heated. Therefore, if filth is put in this incinerator, this filth is incinerated. The outer diameter of the burning pot is smaller than the inner diameter of the boiler body, between the inner periphery of the incineration pan <br/> periphery and boiler body, a gap is formed. The pan support has a plurality of passages from the combustion chamber to the gap .
Since the small holes are formed, exhaust gas in the combustion chamber reaches the vaporizing chamber through the path of the combustion chamber → pot cradle of the small holes → incineration pan and boiler body clearance. In the vaporization chamber, the exhaust gas mixes with the vaporized gas generated by incineration of the waste in the incinerator, and raises the temperature of the vaporized gas to promote the vaporization of the vaporized gas. Thereby, the odor component of the vaporized gas is decomposed, and the vaporized gas is deodorized.

Further , fuel is burned in a vaporization chamber of a boiler body.
A burner may be provided for
Can be further promoted.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows a sectional structure of one embodiment of an incineration boiler according to the present invention, and FIG. 2 shows an appearance of the incineration boiler of this embodiment.

As shown in these figures, in this incineration boiler, a combustion chamber 2 is provided below a substantially cylindrical boiler body 1.
Is formed, and a gas stove 3 is disposed in the combustion chamber 2. Above the combustion chamber 2, a pan support 4 is provided, and an incinerator 5 is placed on the pan support 4. The pan holder 4 is annular, and the bottom of the incineration pan 5 is exposed to the combustion chamber 2 through the hole 4 a inside the pan holder 4. Above the incinerator 5 is a vaporization chamber 6.

The outer diameter of the incinerator 5 is sufficiently smaller than the inner diameter of the boiler body 1, and the outer circumference of the incinerator 5 and the boiler body 1
A gap is formed between the inner circumferences. Further, a plurality of small holes 4b are formed in the pan receiver 4. For this reason, the exhaust gas generated in the gas stove 3 of the combustion chamber 2 reaches the vaporization chamber 6 through the small holes 4 b of the pan support 4 and the gap around the incinerator 5.

On the side wall of the boiler main body 1, a thermocouple 7, a gas burner 8, a waste introduction pipe 9, and an air introduction adjustment pipe 1 are provided.
0 is fixed therethrough.

The heat-sensitive portion at the tip of the thermocouple 7 and the burning portion at the tip of the gas burner 8 are arranged above the incinerator 5.

The tip of the waste introduction pipe 9 is bent downward. The waste introduction pipe 9 is connected to a toilet tank 11 and connected to a pump 12 inside the toilet tank 11. In the toilet tank 11, filth is stored, and the filth is pumped by a pump 12.
Incinerator 5 through the waste introduction pipe 10
Sent to. When the waste is gradually sucked out of the toilet tank 11 and the toilet tank 11 is almost empty, the lower limit float 13
Is lowered, and it is detected that the toilet tank 11 is almost empty.

The air introduction adjusting pipe 10 is provided for introducing an appropriate amount of air into the vaporization chamber 6.

A cover 14 is placed on the upper side of the boiler main body 1. An exhaust hole 15 is formed in the lid 14, and a deodorizing catalyst 16 is provided in the exhaust hole 15.

The boiler body 1 is covered with a heat insulating material so that the boiler does not easily radiate heat. This helps to save fuel and prevent overheating around the boiler.

Now, in the incineration boiler having such a configuration, waste is incinerated in the following procedure.

First, the gas stove 3 and the gas burner 8 are ignited, and gas is burned in each part, the boiler body 1 and the incineration pot 5 are ignited, and the deodorizing catalyst 16 is heated and activated. As a result, the detected temperature of the thermocouple 7 rises. When the detected temperature reaches a predetermined temperature, the pump 12 of the toilet tub 11 is operated for a fixed time to incinerate a substantially constant amount of waste. Feed into pan 5.

The waste from the incinerator 5 is quickly heated, boiled and incinerated since the boiler body 1 and the incinerator 5 are left empty. Thereby, vaporized gas is generated in the incinerator 5, and the vaporized gas fills the vaporization chamber 6.

In the vaporization chamber 6, combustion is performed by a gas burner 8, and the combustion chamber 2 → each small hole 4 of the pan receiver 4.
b → High-temperature exhaust gas is sent in through a gap around the incinerator 5. Therefore, the vaporized gas in the vaporizing chamber 6 is further heated to accelerate vaporization, and the odor component of the vaporized gas is almost decomposed. Thereafter, the exhaust gas and the vaporized gas in the vaporizing chamber 6 pass through the deodorizing catalyst 16 to completely remove the odor, and are discharged from the exhaust holes 15.

As confirmed by experiments, the odor of the vaporized gas can be almost completely removed by heating in the vaporizing chamber 5. For this reason, even if the deodorizing catalyst 16 is removed, the odor of the filth is not felt from the gas discharged from the exhaust hole 15.

Here, when the filth is sent into the incineration pot 5, moisture is accumulated in the incineration pot 5, so that the temperature detected by the thermocouple 7 temporarily decreases. Thereafter, the temperature detected by the thermocouple 7 gradually rises in the process of boiling and burning the filth of the incinerator 5. By the time the incineration of the waste in the incinerator 5 is completed, the temperature detected by the thermocouple 7 reaches a predetermined temperature. At this time, it is determined that the incineration of the waste in the incinerator 5 has been completed.

Subsequently, if any filth remains in the toilet tank 11, a substantially constant amount of filth is sucked out by the pump 12, and the filth is sent to the incineration pot 5, where the filth is incinerated. Such a process is repeated until it is detected that the lower limit float 13 is completely lowered and the toilet tub 11 is empty.

As the waste is repeatedly incinerated, ash accumulates in the incinerator 5. In this case, if the door 17 of the boiler main body 1 is opened and the ash of the incineration pan 5 is sucked out by a dedicated vacuum cleaner, the ash of the incineration pan 5 can be easily discarded.

Further, the lid 14 on the upper side of the boiler main body 1 is removed, and the deodorizing catalyst 16 and the incineration pot 5 are extracted, and the thermocouple 7, the gas burner 8, the filth introduction pipe 9, and the air introduction adjustment pipe 10 are removed. If removed, not only the incinerator 5 but also the boiler body 1 can be cleaned.

In this embodiment, gas is used as fuel, but the present invention is not limited to this, and liquid fuel such as kerosene may be used. Of course, the liquid fuel may be vaporized and then burned.

Further, when the boiler body 1 is tilted due to an earthquake or the like, it is preferable to detect this tilt and extinguish the gas stove 3 and the gas burner 8.

[0030]
