DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a refuse incinerator capable of completely burning refuse and eliminating oily smoke and general smoke accompanying the combustion.

[0002]

2. Description of the Related Art A conventional refuse incinerator comprises a combustion furnace and a chimney, and the chimney is mounted on the combustion furnace. The chimney was still used only for exhaust and smoke emission purposes, and seemed to give little to the combustion itself. Many measures have been taken to increase the combustion efficiency of combustion furnaces and make them burn more completely.However, smoke has not been completely eliminated, and oil and other fumes have not been solved as an environmental problem. The drawback was that it was bothering the neighborhood and the cars that were running.

[0003] Due to these problems, in particular, refuse, soot,
Prevents offensive odors, unburned components, etc. from leaking out and smoke
A garbage incinerator that prevents the occurrence of a sudden red heat phenomenon has been launched.
No. 32236.

According to this, this refuse incinerator is used in a combustion chamber.
And is arranged through an exhaust port formed above the combustion chamber
A chimney, and traverses the combustion gas flow near the exhaust port.
Partition made of air-permeable solid
Is arranged. And the garbage of the burned material
Prevents soot and the like from flowing out to the outside by the partition
At the same time, the temperature of the combustion gas is reduced by the partition.
This will prevent the chimney from becoming red hot.

[0005]

The object of the invention is to be Solved However, the conventional real HirakiAkira
The garbage incinerator shown in No. 58-32236 is a
To prevent spillage of garbage and soot from outside
In addition, the temperature of the combustion gas decreases,
To prevent elephants,
Gas escapes to the outside. Therefore, it leaked out
Influence on others by smoke and gas (neighboring or running cars, etc.
Annoyance etc.) still have environmental issues while issues remain
It was not a solution from the beginning.

The present invention solves the above-mentioned problems.
Innovative garbage burning that can achieve smokeless and odorless during combustion
To provide a rejection machine.

[0007]

Means for Solving the Problems A garbage incinerator according to the present invention has the following configuration to solve the above-mentioned problems. That is, refuse incineration having an outer wall, a combustion furnace disposed in the outer wall, a chimney connected to the combustion furnace, and a flue for smoke generated from the combustion furnace to enter the chimney. Wherein the lower surface of the chimney is located near the bottom of the combustion furnace and a crater cut is formed in the lower surface of the chimney, between the side walls of the combustion furnace and the outer wall and between the bottom surface of the combustion furnace and the side wall. The flue is disposed between bottom walls of the continuously provided outer walls, and the flue is connected to the combustion furnace and the lower surface of the chimney, and maintains a high temperature inside the chimney in the combustion furnace. Hollow heat insulator
But so that the outside of the heat insulator contacts the inner surface of the chimney
An air pipe is provided so as to be able to adjust the amount of air from the bottom of the flue formed between the lower surface of the combustion furnace and the bottom wall into the chimney, and the tip of the air pipe is maintained at the tip. It is characterized by being located immediately below the heat body. Further, the refuse incinerator has an outer wall, a combustion furnace disposed in the outer wall, a chimney connected to the combustion furnace, and a flue through which smoke generated from the combustion furnace enters the chimney. Wherein the lower surface of the chimney is disposed near the bottom surface of the combustion furnace, and a crater cut is formed in the lower surface of the chimney. The chimney is disposed between a bottom wall of an outer wall connected to the furnace bottom surface and the side wall, and the chimney is connected to the combustion furnace and the lower surface of the chimney, and the chimney in the combustion furnace is provided. Hollow heat insulator that maintains high temperature inside
But so that the outside of the heat insulator contacts the inner surface of the chimney
An air pipe is provided so as to be able to adjust the amount of air from the bottom of the flue formed between the lower surface of the combustion furnace and the bottom wall into the chimney, and the tip of the air pipe is maintained at the tip. A chimney outer cylinder is arranged near the lower portion of the heat body and further above the outer wall so as to cover an upper part of the chimney,
An open / close air hole is formed between the chimney outer cylinder and the outer wall.

[0008]

[Operation and effect of the invention] This garbage incinerator has a chimney with a combustion furnace.
Since it is arranged to the bottom, generated smoke is immediately exhausted.
Not issued. In addition, this chimney is
, The surrounding temperature is kept high.

In the chimney, a heat retaining body is provided, so that a high temperature required for secondary combustion is maintained. Then, the smoke generated in the combustion furnace convects in the combustion furnace, flows into the chimney from the lower surface of the chimney, and supplies air in the chimney kept at a high temperature.
This causes secondary combustion.

[0010] Some of the smoke generated in the combustion furnace is in the flue.
Through the chimney and into the chimney from the lower surface of the chimney, causing secondary combustion.
Rub

Further, an air pipe provided in the chimney
The supply of oxygen increases to promote secondary combustion.

That is, if the heat retaining body of the chimney is heated to a high temperature and garbage is charged into the combustion furnace maintained at a high temperature, part of the smoke generated in the combustion furnace flows into the chimney from the combustion furnace. Another part flows through the flue and into the chimney. Then, the smoke that has flowed into the chimney is heated by the heat retaining body and the air pipe to cause secondary combustion and complete combustion, so that smokeless and odorless can be achieved. Also, open and close the space between the chimney outer cylinder and the outer wall.
Since the pores are formed, it should be
The smoke that did not come from the opening / closing air vent through the upper end of the chimney
It can be reburned by the air that has flowed in,
Smokeless and odorless can be achieved.

Therefore, in general, soot (oil smoke) of styrene and vinyl can be easily eliminated and incinerated. Therefore, the refuse incinerator of the present invention can greatly contribute to improvement of environmental problems. In addition, it is clear from the above operation and the figure.
Thus, the present invention provides a superheater for generating secondary combustion.
Does not require a speaker. Uses overheating burner
Running costs because no fuel costs are incurred
This is very practical because it can reduce the number of objects. Further
In the unlikely event that secondary combustion gas or smoke is left,
New combustion by opening and closing air hole formed between cylinder and outer wall
Can generate complete smokeless and odorless
You.
