BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small and medium sized incinerator for incinerating waste such as paper, wood chips, garbage and the like discharged from factories and households.

[0002]

2. Description of the Related Art In a conventional incinerator, the lower end of the incinerator body is grounded on the installation floor, an ash recovery port is provided below the incinerator, and an incineration material input door is provided above the incinerator, and a chimney is directly connected to the upper surface of the body. It was to let.

[0003]

In the conventional incinerator, air required for combustion is taken into the furnace from an ash recovery port or an air intake provided below. Therefore, if the incinerated material is pushed downward to block the inside of the furnace, or if ash accumulates and closes the inside of the furnace, the air required for combustion is limited because air is introduced only from a limited position. Insufficient combustion results in a problem that combustion time is prolonged. Further, the supply amount of air in the furnace is higher near the ash recovery port and the air intake, and is not uniform inside the furnace. Therefore, the combustion state was uneven. Also, this kind of incinerator
Buried an incinerator in the ground and made the internal combustion chamber bottomed
With a structure that perforates air holes on the bottom and side surfaces
As disclosed in Japanese Utility Model Publication No. 53-196322,
Is buried underground, so it is difficult to collect ash and burn
The air guide hole is closed by dust and air introduction becomes insufficient,
In addition, the air-guiding area tends to be short and the outside air can be strongly sucked from below.
However, there is a problem that combustion becomes insufficient.

[0004] The problem to be solved by the present invention is to solve these conventional problems, to supply a sufficient amount of air and to enable uniform combustion to improve the combustion state.
Shorter incineration time and easier and faster ash recovery
It is to provide an incinerator that can do it.

[0005]

The gist of the present invention that solves the above problem is that an incineration material charging section is provided on a side wall of a cylindrical body having an open bottom, and an ash-dropping grid is provided in a lower part slightly above the lower end of the body. A chimney is attached to the upper part of the fuselage, and the fuselage is set up at a predetermined height above the installation floor, and furthermore, a ring body surrounding the lower part of the fuselage at an outer peripheral position separated by a predetermined distance from the outer wall surface of the fuselage It was placed, and openably provided ash collection door on a part of the outer periphery of the ring body, upper torso

Form a bypass air intake passage that takes air into the chimney
In the incinerator. Here, the cross-sectional shape of the body is cylindrical and square.
Any shape may be used, and the shape is not limited.
No.

[0006]

According to the present invention, the tubular body is installed in a raised state, and there is a predetermined height interval between the lower edge thereof and the installation floor. Also, since a predetermined distance is provided between the outer ring body and the fuselage, an annular ventilation path is formed between the ring inner wall, the fuselage outer wall, and the floor surface for communicating the atmosphere with the fuselage interior. The air is uniformly sucked from the entire periphery of the lower edge of the body.

Further, the air passing through the ventilation passage is heated and sucked while descending along the outer wall surface of the body heated by combustion. The air sucked from the opening at the bottom of the fuselage tends to rise along the wall of the fuselage and burns the incinerated material from outside to inside. Further, the outer ring body prevents the rainwater / wind from directly flowing into the body, thereby avoiding adverse effects of the rainwater / wind on combustion. The ring body prevents the ash that has fallen from the ash ash grid of the fuselage from flowing out due to wind and rain. In addition, the ash that has fallen on the installation floor is collected as a ring-shaped ash.
Open the door and scrape the ash along the installation floor surface for easy and quick
It can be quickly discharged out of the ring body.

[0008] Further, the smoke outlet of the body is disposed in the smoke inlet of the larger chimney, and a ring body is provided on the outer periphery thereof , and the air intake is provided .
An air passage between the fuselage and the chimney
In the air intake passage , the above-mentioned air suction phenomenon occurs, and secondary combustion is performed in the chimney, and complete combustion is performed to suppress the generation of unburned toxic gas. Make smoke good.

In this embodiment, incinerated materials, such as paper, wood, plastic, etc., are introduced into the body 1 from a door type incinerated material input section 2. When the incinerated material is ignited and the combustion starts, the combustion heat causes an upward flow in the body, and the combustion gas and smoke pass through the first and second chimneys 4 and 5 together with the air and are released to the atmosphere. . If it burns, the fuselage 1 will be heated and a strong airflow rising force will be generated inside the fuselage 1, and a negative pressure will be generated at the bottom opening of the fuselage 1, which will be formed by the ring 7, the installation floor 6, and the lower outer wall of the fuselage 1. Air is uniformly sucked from the annular air passage 15 into the body 1.

The uniform and sufficient intake of air into the body 1 enables uniform combustion. Moreover, the body 1
By introducing the air heated in the above, the combustion state is improved. A similar phenomenon occurs at the connecting portion between the body 1 and the first chimney 4 and at the connecting portion between the first chimney 4 and the second chimney 5, air is uniformly sucked from each of the annular ventilation passages 16 and 17, and good combustion is achieved. It is assumed that Here, inside the first chimney 4,
The secondary combustion is mainly performed by sucking the air from the annular ventilation path 16 to prevent the generation of unburned gas, generate a strong updraft due to the high heat of combustion, and smooth the smoke exhaust. In the second chimney 5, similarly, air is sucked from the annular ventilation passage 17 to dilute the combustion gas, and also, the chimney is prevented from being heated up, and the smoke is smoothly discharged. Therefore, in this example, the combustion of the incinerated material was completed, and the smoke and exhaust gas from the chimney were free from unburned parts, soot, and odor.
