Description

[Detailed description of the invention]

[0001]

[Industrial application field] The present invention is applicable to general homes, factories, shops,
The present invention relates to a simple incinerator used to incinerate combustible waste such as garbage at schools.

[0002]

2. Description of the Related Art A conventional incinerator generally comprises a cylindrical combustion chamber and a chimney provided on a lid of the combustion chamber. And
At the lower part of the combustion chamber, there is formed an ignition port which opens on the upper side of the roaster and an air inlet which opens on the lower side of the roaster, and the lid of the combustion chamber is half-opened to serve as a dust inlet.

[0003]

In the above-mentioned conventional incinerator, since the lid is opened and garbage is charged, the ignition port is opened and ignited by incineration, the garbage burns from the bottom. Therefore, when a large amount of garbage is pushed in and burned, there is not enough space in the garbage to not only burn well, but also generate a large amount of colored, odorous and harmful incomplete combustion gas. Become. Therefore, the conventional incinerator cannot incinerate a large amount of garbage at a time, the incineration time is slow, the incineration efficiency is low, and there is a possibility that harmful gas may be generated. In addition, in the case of a conventional incinerator, an auxiliary fuel is often used to increase the combustion power. Therefore, an object of the present invention is to provide an incinerator that can completely and quickly incinerate a large amount of garbage without generating harmful gas and without using auxiliary fuel.

[0004]

SUMMARY OF THE INVENTION According to the present invention, a bottom roster is disposed at a lower portion of a combustion chamber, and a center portion of the bottom rostre is provided.
A vertical rostral extending up to the upper end of the combustion chamber is erected, and an ignition port and an air intake opening below the bottom rostral are provided at a lower portion of the combustion chamber.
A lid having a chimney and capable of being fully or partially opened is attached, and the vertical loss is provided at the base of the chimney with respect to the lid.
Larger diameter than Torr, with metal mesh layer inside
The above problem was solved by an incinerator having a re-combustion chamber . Preferably, a combustion suppressing cylinder is provided on an upper end of the vertical roaster.

[0005]

[Operation] Since there is a vertical roaster as a combustion cylinder in the center, refuse can be satisfactorily burned from the inside, and incompletely burned gas is reburned in the heated vertical roaster. When the re-burning chamber is provided, the metal mesh layer is heated within a short time after the start of combustion, so that the incomplete combustion gas that has not been completely re-burned in the vertical roaster is re-burned there,
It is emitted as a non-polluting gas from the chimney.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a partial sectional front view of the incinerator according to the present invention, and FIG.
Is a partial sectional front view thereof. In the figure, reference numeral 1 denotes a metal combustion chamber similar to the conventional one, which usually has a cylindrical shape. On the inner bottom of the combustion chamber 1, there is generally provided a bottom rostrole 2 having a large number of heat-resistant rods arranged radially and having their ends bent downward along the inner surface of the combustion chamber 1. You. The central part of the bottom part 2 is recessed to form a shallow mortar.

[0007] At the center of the bottom part 2, a vertical part 3 is installed. The vertical rostru 3 is made by arranging bars similar to the above in a circular shape, and the support member 4 is fixed to the inside or outside thereof as appropriate to maintain the cylindrical state. The vertical rostral 3 may be a porous long cylinder. Preferably, a combustion suppression cylinder 5 is fitted to the upper end of the vertical roaster 3.

[0008] At the lower end of the combustion chamber 1, an openable ignition port 6 is provided which is open to the lower surface side of the bottom rostral 2, and an air intake port 7, whose opening is preferably adjustable, is provided.
Or a plurality is installed. The igniter 6 also serves as an outlet for the ash stored under the bottom rostral 2. On the upper surface of the combustion chamber 1, a lid 8 provided with a chimney 10 is provided via a re-combustion chamber 9. The lid 8 may be a fully open type or a half open type.

The re-combustion chamber 9 is wider than the vertical roaster 3, and a downwardly extending combustion suppression tube fitting portion 11 is formed at the lower surface opening thereof. The upper end of the combustion suppression tube 5 is fitted therein. Is done. Normally, the recombustion chamber 9 is integrated with the lower end of the chimney 10. Reference numeral 12 denotes a metal net layer such as a thin iron wire provided from the upper portion of the re-combustion chamber 9 to the lower portion of the chimney 10.

When the incinerator according to the present invention having the above structure is used, the lid 8 is opened and dust is introduced into the combustion chamber 1. However, unlike the conventional incinerator, a large amount of dust may be pushed. Absent. After the lid 8 is closed, when old newspaper or the like is inserted through the ignition port 6 and ignited, the garbage is transferred to the garbage in contact with the surroundings of the vertical roaster 3, and the garbage is burned from the inside. Therefore, the outside surface of the combustion chamber 1 does not become so hot, so there is no danger. Since the air taken in from the air inlet 7 flows through the vertical roaster 3, dust around the vertical roaster 3 burns well.

A combustion suppressing cylinder 5 is fitted on the upper part of the vertical roaster 3 to suppress the burning of dust around it. As a result, the unburned debris in the upper part collapses inward toward the vertical roaster 3 as the debris around the lower part of the vertical roaster 3 burns.

After the start of combustion, the hot air rises again from the vertical roaster 3 into the recombustion chamber 9, so that the vertical roaster 3 and the metal mesh layer 12 are heated within a short time, and the temperature becomes considerably high. As a result, the incompletely burned gas that has escaped into the vertical roaster 3 is reburned there, and the gas that has not been completely burned there is reburned in the reburning chamber 9.
By the way, since the diameter of the re-combustion chamber 9 is larger than that of the vertical roaster 3, the gas that has risen up the vertical roaster 3 temporarily stays there without going into it and escaping at once. By making full contact with the metal mesh layer 12 that has been used, complete combustion is ensured.

[0013]

[Effects of the Invention] Since the present invention is as described above, it can be provided at a price that is not so different from the conventional one with a simple configuration.
The garbage burns from the inside in good condition because it has a rostral extending vertically in the center as well as the bottom,
In addition, the incompletely combusted gas is re-burned and re-burned (completely burned) in the vertical roaster and the after-burning chamber,
It has the effect of being emitted as non-polluting gas.
