2. Description of the Related Art A conventional incinerator has a structure shown in FIG.

FIG. 6 is a cross-sectional view showing the entire main structure of a conventional dry distillation type incinerator.

In FIG. 6, the primary combustion chamber 10 has an inlet 11 for incinerated matter at the upper part, an outlet 12 for incinerated ash at the lower part, and an explosion-proof valve 13 at the upper end. . The primary combustion fan 14 introduces outside air into the primary combustion chamber 10 and supplies oxygen to the incinerated material. This primary combustion chamber 10
Although the entire outside of the incinerator is in the shape of a rectangular parallelepiped, the partition plate 15 made of a refractory material in the middle is formed so as to be inclined so that the lower plane area is smaller than the upper plane area.

The secondary combustion chamber 20 has an exhaust gas outlet 21 at the upper end and an incineration ash outlet 22 at the bottom. The exhaust gas from the exhaust port 21 is discharged to the atmosphere from the chimney 24 through the cyclone 23. The cyclone 23 separates dust such as combustion gas, which is wound up by the combustion gas, from the combustion gas and lowers it. The secondary combustion chamber 20 is partitioned by the sloping partition plate 15 so that the lower plane area is larger than the upper plane area.

The cooling water tank 30 prevents the temperature rise of each wall surface of the incinerator including the primary combustion chamber 10 and the secondary combustion chamber 20 excluding the door portion, and enhances the durability of the incinerator.
Naturally, it is also supplied to the partition plate 15.

A combustion pipe 40 provided in the lower portion of the primary combustion chamber 10 located on the side of the incineration product inlet 11 is formed in a cylindrical shape, and connects the lower portion of the primary combustion chamber 10 and the lower portion of the secondary combustion chamber 20. It is in communication. A plurality of air nozzles 51 are arranged around the combustion pipe 40, and the air blown out from the secondary combustion fan 50 is ejected to burn inside the combustion pipe 40. In addition, air is ejected from the secondary combustion fan 50 by the air nozzle 52 from the lower portion of the combustion casing 17 arranged in front of the combustion pipe 40. The valve 50A
Reference numerals 50B and 50B are for opening / closing control for setting the timing at which air is ejected.

In the lower part of the combustion rod 17 of the primary combustion chamber 10,
An ignition burner 60 is provided, and receives fuel such as heavy oil and LP gas to decompose the incinerated matter that has been put into the primary combustion chamber 10.

Further, the combustion pipe 40 under the secondary combustion chamber 20

1 is sealed.

Therefore, the outside air is introduced into the primary combustion chamber 10 by the primary combustion fan 14, and the ignition burner 60 is also provided.
Ignite The ignition of the ignition burner 60 raises the temperature in the primary combustion chamber 10, thereby decomposing the incinerated matter,
It becomes combustion gas. At the same time, the combustion preheater 41 is heated,
Combustion is started near the combustion pipe 40. Therefore, the combustion tube 4
Air is ejected from the air nozzle 52 in front of 0,
Air is ejected from a plurality of air nozzles 51 around the combustion tube 40, and further, the smoke eliminating burner 61 behind the combustion tube 40 in the secondary combustion chamber 20 is ignited. As a result, the incineration material in the primary combustion chamber 10 is decomposed into combustion gas, and the combustion preheater 4

In the figure, a combustion tube 40 provided in the lower portion of the primary combustion chamber 10 is formed in a cylindrical shape, and the primary combustion chamber 1
The lower part of 0 and the lower part of the secondary combustion chamber 20 are communicated with each other, and burns the combustion gas generated from the incinerated material 90 (see FIG. 5) injected into the primary combustion chamber 10 inside. Therefore, a plurality of air nozzles 51 are arranged around the combustion tube 40, and the air blown out from the secondary combustion fan 50 (see FIG. 6) is ejected to perform combustion in the combustion tube 40. ing. Air is also jetted from the lower part of the combustion colander 17 arranged in front of the combustion pipe 40 by the air nozzle 52 (see FIG. 6).

In the lower part of the combustion rod 17 of the primary combustion chamber 10,
An ignition burner 60 is provided, and the secondary combustion chamber 2
A smoke eliminating burner 61 is also disposed behind the combustion pipe 40 in the lower part of 0, and is decomposed in the primary combustion chamber 10
The remaining combustion components burned at 0 are burned completely. A combustion preheater 41 is disposed in front of the combustion tube 40, and heat of the ignition burner 60 and the primary combustion chamber 1 are provided.
The combustion tube 40 is heated by the combustion gas burning at 0
The temperature of the combustion gas that leads to is high.

In front of the combustion preheater 41 at the inlet of the combustion tube 40, a vertical lattice 70 is arranged so that the incinerated matter 90 thrown into the primary combustion chamber 10 does not directly enter. The vertical grid 70 has a grid interval set in accordance with the size of the main incinerated material 90. Usually, the lattice spacing is obliquely arranged and set to a spacing of about 3 to 10 [cm]. The vertical grid 70 has the function of increasing the temperature of the combustion gas that is heated by the heat of the ignition burner 60 and the combustion gas that is burning in the primary combustion chamber 10 due to its heat capacity and is guided to the combustion tube 40. In addition, as will be described later, the function of the melt holder 80 can be provided.

Further, at the lower end of the partition plate 15 for partitioning the primary combustion chamber 10 and the secondary combustion chamber 20, the central bent end portion 81 of the inverted V-shaped melt holder 80 is located and opened. Leg end 8
0a and 80b are located on the upper part of the burning coffin 17. This inverted V-shaped melt retainer 80 is formed by bending a round bar having a diameter of about 8 to 20 [mm] so that the heat capacity above a predetermined level can be maintained. The portion 81 is curved with an appropriate curvature.

However, the vertical grating 70 may be omitted when implementing the present invention. That is, as shown in FIG. 4, the vertical grid 70 may be omitted. This can be the second embodiment.

The conventional dry-distillation type incinerator thus constructed operates as follows. In particular, in order to simplify the description, the configuration of the second embodiment will be described.

As in the conventional case, the charging port 1 of the primary combustion chamber 10
The incinerator 90 is charged from 1 and the charging port 11 is closed when a predetermined amount of the incinerator 90 is charged. Outside air is introduced into the primary combustion chamber 10 by the primary combustion fan 14, and the ignition burner 60 is ignited. The incineration material 90 in the primary combustion chamber 10 is thermally decomposed by the ignition of the ignition burner 60, and the incineration material 90 becomes combustion gas. At the same time, the combustion preheater 41 is heated and combustion is started near the combustion pipe 40. Therefore, air is ejected from an air nozzle 52 in front of the combustion pipe 40, and a plurality of air nozzles 51 around the combustion pipe 40 are provided.
From the combustion pipe 4 of the secondary combustion chamber 20.
The smoke extinguishing burner 61 behind 0 is ignited. As a result, the incineration material 90 in the primary combustion chamber 10 is decomposed into combustion gas, which is heated by the combustion preheater 41, air is ejected from the air nozzle 52 in front of the combustion pipe 40, and the surrounding of the combustion pipe 40 is also ejected. By ejecting air from the plurality of air nozzles 51, the combustion in the combustion tube 40 is burned in a state close to complete combustion. Further, the smoke extinguishing burner 61 behind the combustion pipe 40 of the secondary combustion chamber 20 burns the combustion components that could not be completely burned by the combustion in the combustion pipe 40, and discharges the exhaust gas from the exhaust port 21.

At this time, the incinerated material 90 put into the primary combustion chamber 10 is usually placed in an atmosphere at a temperature of 170 to 300 ° C. and decomposed at that temperature. Although it softens or the rubber component melts, it falls on the surface of the partition plate 15 and the combustion preheater 41
Run down to the side. When the rubber or synthetic resin softens and flows down, it becomes a viscous nodule having a high viscosity. The surface tension of the viscous nodule acts to reduce the surface area. The viscous nodule rides on the central bent end 81 of the inverted V-shaped melt retainer 80 and flows down toward the open leg end 80a and open leg end 80b. At this time, the integrated viscous nodule is divided into two parts, and the heated melt holder 80 causes the contact portion, the ignition burner 60, and the primary combustion chamber 10 to come into contact.
It is heated by the combustion gas that is burning in and decomposed into combustion gas.

In particular, the viscous nodule that has been integrated is divided into two parts on both sides when flowing down in the direction of the open leg end portion 80a and open leg end portion 80b, and while being pulled in the direction of gradually widening the interval, It flows down in the direction of the leg end portion 80a and the open leg end portion 80b, widens the surface area of the viscous nodule, and makes it easier to decompose into combustion gas. Therefore, in a normal operation state, the synthetic resin or the like softens and descends on the surface of the partition plate 15,
When flowing from the central bent end 81 of the inverted substantially V-shaped melt retainer 80 toward the open leg end 80a and the open leg end 80b, a viscous nodule is divided into two and the heated melt retainer is held. Ingredient 80
It is heated by itself, the ignition burner 60, and the combustion gas burning in the primary combustion chamber 10, and is efficiently decomposed into combustion gas.

Therefore, even if the synthetic resin or the like introduced into the primary combustion chamber 10 softens and descends on the surface of the partition plate 15 made of a refractory material, it adheres to the surface of the combustion preheater 41 and the combustion preheater 41.
Of the combustion pipe 40
There is no adverse effect such as changing the amount of air and the amount of combustion gas that passes through, and as a result, a good combustion state can be maintained and incomplete combustion does not occur.

By the way, the inverted V-shaped melt retainer 80 arranged at the lower end of the partition plate 15 for partitioning the primary combustion chamber 10 and the secondary combustion chamber 20 in the above-mentioned embodiment has a central bent end. It is bent at the portion 81 and is provided with the open leg end portions 80a and 80b.
Although it is formed by bending a round bar having a diameter of about 20 [mm], in the case of carrying out the present invention, the viscous nodule softened by heat is divided into a plurality of pieces, and is efficiently chemically converted into combustion gas. Since it suffices to obtain a physical change so as to be decomposed, it is sufficient to use a constituent member having a narrow upper interval and a wide lower interval. Therefore, the inverted V-shaped melted material holders 80 can also be double-mounted with different open angles.

In other words, in this sense, the vertical lattice 70 arranged in front of the combustion preheater 41 at the inlet of the combustion pipe 40 is divided into a plurality of heat-softened nodular nodules as shown in FIG. Since it suffices to obtain a physical change so as to be chemically decomposed into combustion gas well, it is sufficient to use a constituent member having a narrow upper interval and a wide lower interval. Further, in particular, the vertical lattice 70 has a predetermined heat capacity,
More effective combustion gasification of viscous nodules becomes possible.

In the first and second embodiments described above, the inverted V-shaped melt holder 80 is used, but when the present invention is carried out, it is extended from the partition plate 15. The upper space may be narrower and the lower space may be wider.

Further, in the above embodiment, the melt holder 80
Is configured such that the upper space is narrow and the lower space is wide. However, when the present invention is carried out, depending on the selection of the heat capacity of the melt holder 80, the upper space and the lower space may be different. The intervals may be the same.

Furthermore, as in the present embodiment, the melt holder 80 is adapted to receive the viscous nodule softened by the heat flowing down from the inclined surface of the partition plate 15. Alternatively, the flow may be received from another inclined surface. However, as in the embodiment of the present invention, the partition plate 1
When 5 is tilted, the whole structure of the furnace can be made compact.

Therefore, even if the synthetic resin or the like softens in the primary combustion chamber 10 and moves down the wall surface of the primary combustion chamber 10, the molten material holder 80 is moved to the upper portion and placed in a high temperature atmosphere. The rate of decomposition into combustion gas can be increased so that the combustion state is not affected. Therefore, even if the synthetic resin or the like is softened and descends the wall surface of the primary combustion chamber, the combustion state is not affected.

Therefore, even if the synthetic resin or the like softens in the primary combustion chamber 10 and moves down the wall surface of the primary combustion chamber 10, the molten material holder 80 is moved to the upper portion and placed in a high temperature atmosphere. The rate of decomposition into combustion gas was increased so that the combustion state was not affected. In particular, softened synthetic resin or the like is burned from the lower part of the burning rod 17,
Even when the wall surface of the primary combustion chamber 10 is lowered, the melt holder 80
By moving it to the upper part and placing it in a high temperature atmosphere, the rate of decomposition into combustion gas is increased, and the speed of decomposition into combustion gas is increased. Therefore, even if the synthetic resin or the like is softened and descends the wall surface of the primary combustion chamber, the combustion state is not affected.

In the incinerator of the above-described embodiment, the molten material holder 80 inclinedly arranged in the lower portion of the primary combustion chamber 10 is the primary combustion chamber 1

In the incinerator according to any one of claims 1 to 3, the melt holder 80 of the above embodiment has a narrow upper portion and a wide lower portion. Yes, this can be the embodiment of claim 4. Therefore, the softened material such as synthetic resin that has flowed down like a viscous nodule will descend while being pulled on both sides,

It becomes easy to soften into combustion gas.

The melt holder 80 of the above embodiment is formed continuously from the wall surface of the primary combustion chamber 10 such that the width of the upper portion is narrowed and the width of the lower portion is widened. It is the incinerator according to any one of claims 5 and can be the embodiment of claim 6. Therefore,
Since the width of the upper part is narrowed and the width of the lower part is formed continuously from the wall surface of the primary combustion chamber 10, the softened material such as synthetic resin flowing down like a viscous nodule is lowered while being pulled on both sides. However, the viscous nodule is divided and becomes smaller, and its surface area is increased, so that it becomes easy to turn into combustion gas.

The melt holder 80 of the above embodiment is provided below the primary combustion chamber 10 located on the incineration material inlet 11 side and the secondary combustion chamber 20 located on the exhaust gas exhaust side after combustion. The combustion pipe 40, which connects the primary combustion chamber 10 and the secondary combustion chamber 20 to each other, is located in front of a combustion preheater 41 disposed in a front opening inside the primary combustion chamber 10, and the primary combustion chamber is provided.
