Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an incinerator for incinerating household, general, and industrial wastes, and more specifically, to reduce unburned gas and unburned gas as much as possible. It concerns the structure of the devised incinerator.

[0002]

2. Description of the Related Art In a conventional incinerator, unburned gas and unburned gas increase when the temperature in the furnace chamber decreases when the thermal power in the furnace chamber becomes weak near the start and end of combustion. However, there is a drawback that those gases are released into the atmosphere as they are and pollute the atmosphere.

In particular, in an incinerator which is portable and does not have a chimney or has an extremely short chimney, and which incinerates general waste in a relatively small scale, the equipment cost is suppressed and the combustion cost is reduced. In order to do so, the auxiliary combustion chamber was omitted or the structure was suppressed to a small scale, so there was a drawback that the release of unburned gas and incompletely burned gas to some extent was unavoidable, and there was also an incinerator. There was also a restriction that it could not be enlarged.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the drawbacks described in the prior art, without the need for installing a long chimney or an expensive and large-scale incinerator as in the prior art. The object of the present invention is to provide an incinerator that can reduce unburned gas and unburned gas as much as possible at low cost.

[0005]

Means for Solving the Problems At appropriate places in a furnace chamber, a partition having an air hole, a partition having a tropical zone, a partition having a blade, a partition made of fine ceramics having a burning ball effect, or a fine ceramics It has a mesh-shaped or honeycomb-shaped partition wall containing small particles.

[0006]

When the unburned gas or the unburned gas comes into contact with the partition having the air holes, a part of the gas circulates in the central part of the furnace chamber,
It burns, and the rest escapes from the air holes so as not to weaken the firepower. That is, the air hole functions as a control valve.

When unburned gas or incombustible gas stagnating inside the partition wall tends to be deficient in oxygen and comes into contact with the partition wall having a tropical zone, the gas is forcibly heated and burned.

When the unburned gas or the unburned gas comes into contact with the partition wall having the blade, an air flow is generated along the curved surface of the blade, and the unburned gas or the unburned gas is circulated in the central portion of the furnace chamber. , Burn those gases.

When uncombusted gas or non-combusted gas comes into contact with the partition wall made of fine ceramics having a hot-ball effect,
The gas is heated and burns. Further, fine ceramics generate far infrared rays and heat particles such as soot in the unburned gas or the unburned gas, which is effective.

When uncombusted gas or noncombustible gas comes into contact with the mesh-shaped or honeycomb-shaped partition walls containing small particles of fine ceramics, the gas is heated, and the far infrared rays generated from the fine ceramics cause soot in the gas. The particles are heated, so that the combustion efficiency is further improved. Further, since it has a mesh shape and a honeycomb shape, the frequency of contact of unburned gas and non-burned gas is dramatically increased, which is effective.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to explain the drawings showing an example of the embodiment of the present invention, FIG.
As shown in FIG. 3, partition walls 3 made of ceramics or the like having air holes 2 are provided. For example, as shown in the cross-sectional view in FIG. Partition wall 3 having honeycomb-shaped exothermic zone 5, as shown in FIG. 4, air holes 2 at appropriate locations.
A partition wall 3 made of ceramics or the like having an open blade 6, as shown in FIG. 5, and a partition wall 3 made of fine ceramics having a fired ball effect in which air holes 2 are opened at appropriate places, as shown in FIG. A mesh-shaped partition wall 3 containing small particles of fine ceramics or a honeycomb partition wall 3 containing small particles of fine ceramics, as shown in FIG.

FIG. 1 shows an example in which the partition wall 3 is installed on the ceiling of the furnace chamber. However, the position is not limited to this position, and unburned gas and unburned gas are likely to stagnate.
Can be applied anywhere. Although the partition wall 3 shown in FIG. 1 has a conical shape, it is not limited to this shape, and it is most effective at a place such as a disc, a polygon, a concave shape, and a convex shape depending on the installation location. Various shapes can be selected.

In FIG. 1, 7 is a furnace chamber upper lid, 8 is a chimney, 9 is an air pipe, and 10 is a grate. Also, the partition 3
It is preferable to divide the unit into units of an appropriate size that are easy to assemble and attach and detach so that economical mass production is possible. The air holes 2, the tropical zone 5, the mesh, etc. are controlled by adjusting the energizing current value according to the temperature in the furnace, the smoke concentration, the odor concentration, etc.
You may be allowed to do this.

[0014]

[Effect] Since the present invention is configured as described above,
It has the following effects.

Since the unburned gas and the unburned gas burn almost completely, odors and soot can be removed from the exhaust gas.

The tropics of ceramics or ceramic fibers generate far infrared rays to accelerate combustion.

Combustion efficiency is further improved by forming the partition walls into a mesh or honeycomb shape containing fine ceramic particles.

Since the secondary combustion chamber and the chimney are extremely small and can be omitted in some cases, the equipment cost can be greatly reduced.

For burning unburned gas and unburned gas,
Since it does not use heavy oil, it is clean and saves resources.

Since the partition has a simple structure, it can be mass-produced. The present invention has the above-mentioned remarkable effects and has a high industrial utility value.
