Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a dust incinerator, especially waste paper,
The present invention relates to an incinerator that is suitable for incinerating combustible waste such as wood chips and pieces of cloth.

[0002]

2. Description of the Related Art Disposal of so-called dust (garbage) has become a serious social problem, and measures such as so-called separate collection of garbage have been taken, but originally, the garbage problem should be treated as much as possible at the source. Is preferred. As for the garbage generated in the household, flammable garbage can be incinerated in each household as much as possible, and the amount of generated garbage can be greatly reduced. Conventionally, incinerators of various types, from simple and small ones with a chimney to the ones to oil- or gas-assisted combustion to full-scale incinerators with a built-in dust collector. It has been known.

[0003]

However, when incinerating waste in a general household, it is not possible to equip the household with an incinerator with a built-in dust collector, and even an oil- or gas-assisted incinerator, In practice, it is difficult to use due to various restrictions. Usually, at home, a small and simple one with a chimney attached to the furnace is often used, but combustion efficiency is poor with just a chimney attached to the furnace, and a large amount of smoke is generated due to the burning of dust,
In particular, white smoke is generated, so it is virtually impossible to use in densely populated areas of the city. For this reason, the waste generated at home is left to the public institution to collect the waste without being incinerated, and as a matter of fact, the waste problem still cannot be solved.

It is an object of the present invention to provide an incinerator which has a simple structure in which a chimney is attached to the furnace, but produces almost no smoke.

[0005]

To achieve the above object, the incinerator according to the present invention is an incinerator filled with a far-infrared functional material, the far-infrared functional material being heated by combustion of the incinerated material. , A far-infrared radiation source that radiates thermal energy in the wavelength range of 2.5 to 1,000 μm.

Further, the far-infrared functional material is an amorphous solid substance, and a large number of solid substances are packed in layers in a combustion chamber of an incinerator.

The solid layer of the far-infrared functional material is supported by a mesh cylinder inserted into the combustion chamber and is filled to a constant thickness along the inner wall of the combustion chamber. It forms a gap that communicates. It is a thing.

[0008]

The present invention utilizes the radiation of far-infrared energy emitted by the far-infrared radiation functional material to enhance the burning efficiency of dust. Far infrared rays are infrared rays having a very long wavelength among infrared rays. Although there is no clear boundary, it indicates an infrared ray having a wavelength of about 2.5 to 1,000 μm, and this wavelength range is called a far infrared range. There are three types of heat transfer, "conduction", "convection", and "radiation". Of these, infrared heating is a method of heating by radiation of heat energy and generates it. Material is called infrared radiation functional material (New Material Handbook 1988
(See p. 78-82, Intergovernmental Materials Research Committee). The material that generates far infrared energy is a far infrared radiation functional material.

As a typical far infrared radiation functional material,
Ceramics containing zirconium oxide and silicon oxide, which have large long-wavelength emissivity, as main components are known. This ceramic is 5-2 when it is secondarily heated by another heat source.
It radiates far infrared energy in the radiation wavelength region of 5 μm, and this ceramic is industrially used as a material for a far infrared heater.

The far-infrared radiation functional material is not limited to artificially produced ceramics, but can be obtained from natural stones containing zirconium oxide, silicon oxide and other components having the same effect as main components. For example, natural stone commercially available as pyroxene andesite is an effective far-infrared radiation functional material. If pyroxene andesite is crushed and filled in the combustion chamber of an incinerator, heat energy is radiated by using heat generated by combustion of waste as a heat source, combustion efficiency of incineration is increased, and generation of smoke can be significantly reduced.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, the incinerator shows a small household incinerator in which the chimney 2 is only attached to the furnace body 1. In this type of incinerator, a dust inlet is provided on a part of the upper surface of the furnace body 1, and the inlet is closed by a lid 3. An air intake 4 is opened at the bottom of the furnace body 1, and a sludge 6 is installed at the bottom of the combustion chamber 5 in the furnace body. The chimney 2 is attached to the upper part of the furnace body 1 so as to communicate with the combustion chamber 5.

In the present invention, as shown in FIGS. 2 and 3, a net cylinder 7 is provided inside the combustion chamber 5 of the furnace body 1, and the net cylinder 7 and
The far-infrared radiation functional material 8 is filled in the gap formed between the combustion chamber 5 and the inner wall thereof. As the far-infrared radiation function material 8, for example, natural stone known as pyroxene andesite is crushed and the crushed stone is filled. The size of the crushed stone is not necessarily limited, but it is preferable that the crushed stone is crushed in an irregular shape to form a gap in the layer of crushed stone. A gap is formed between the net cylinder 7 and the crushed stone filled between the inner walls of the combustion chamber 5, and this serves as a flue leading to the chimney.

Combustible waste such as waste paper, wood waste, rags, and dead leaves is put into the combustion chamber 5 through the inlet, and the lid 3 is closed.
When this is combusted, the heat generated by the combustion serves as a heat source to secondarily heat the far-infrared radiation functional material 8 and radiate thermal energy to increase the combustion efficiency of dust in the combustion chamber 5, resulting in incomplete combustion. Combustion gas emitted from the inner layer portion of the layer of the combustible substance M in the combustion chamber, which easily occurs, flows out in the circumferential direction, passes through the mesh cylinder 7, and flows into the gap between the layers of the far-infrared radiation functional material 8.
The heat energy is radiated and completely burned, and as it is, it rises in the gap between the layers of the far-infrared radiation function material 8 and is emitted from the upper part of the combustion chamber through the chimney 2 to the outside air.

A large amount of white smoke is generated by the incomplete combustion of the combustible material, but the combustion gas emitted from the inner layer of the layer of the combustible material M, which easily causes the incomplete combustion, rises in the gap between the far infrared radiation functional material layers. In the meantime, it burns completely and almost no white smoke is produced.

A height of 320 mm and a diameter of 27 are provided in an incinerator having a cylindrical combustion chamber having a height of 500 mm and a diameter of 350 mmφ.
A mesh cylinder with a rough mesh of 0 mmφ is concentrically installed, and 17 kg of pyroxene andesite crushed into an irregular shape with a diameter of several cm is filled between the mesh cylinder and the inner wall of the combustion chamber. ， When we put combustible material including waste paper into the combustion chamber and burned it, white smoke was observed immediately after the start of combustion, but after that, the white smoke disappeared until the combustion ended. Almost no white smoke was observed during this period.

On the other hand, when the same amount of combustible material was incinerated under the same conditions without filling pyroxene andesite, white smoke was observed from immediately after the start of combustion, and white smoke was not generated. , Only for a short period of time, when all the flammable materials seemed to be burning in red heat.

[0017]

As described above, according to the present invention, the thermal energy radiation by the secondary heating of the far-infrared radiation functional material is effectively utilized to enhance the combustion efficiency, and the incineration is performed without generating smoke when burning the combustible waste. be able to. In particular, the periphery of the combustion chamber is filled with a layer of amorphous far-infrared radiation functional material,
The combustion gas generated by the incomplete combustion can be effectively re-combusted while passing through the gap between the far-infrared radiation functional material layers to eliminate the generation of smoke from the chimney. Further, the far-infrared radiation functional material is not limited to artificially produced materials such as ceramics, but natural stone can be used. ADVANTAGE OF THE INVENTION According to this invention, substantially smokeless can be implement | achieved, without using combustion energy like gas and oil for incineration of garbage, and the outstanding effect as a general incinerator, especially a domestic incinerator is acquired. .
