(Method of Incineration of Waste by Vertical Incinerator of First Invention :) The incineration of waste (incineration) by the vertical incinerator of the first invention is performed as follows.

First, after incinerated material is put into the carbonization chamber 1,
The auxiliary combustion device 7 is started. The combustion flame from the auxiliary combustion device 7 (: an auxiliary combustion flame) rises in a gas flow path S which is surrounded by the lattice surface of the carbonization gas introduction lattice 4 and is formed vertically, and is introduced into the combustion cylinder 2.

(Basic structure and constituent members of the vertical incinerator of the first invention :) The vertical incinerator of the present invention illustrated in FIGS.

Auxiliary combustion device 7 for supplying combustion flame (: auxiliary combustion flame) to combustion cylinder 2 via a combustion chamber. (Situation of arrangement of each basic constituent member of first invention :) (combustion cylinder 2 :) 1. As shown in FIG.
Are arranged vertically in the center of the transverse section (horizontal section) of the carbonization chamber 1. (The conical member 17 disposed above the opening 3a of the main combustion air supply pipe 3 :) In the vertical incinerator of the first invention, as shown in FIGS. Air supply piping 3
The conical member 17 is disposed above the opening 3a so that the apex of the conical member 17 is located above the center of the opening 3a in opposition to the opening 3a.

In the present invention, the following effects can be obtained by the above-described arrangement of the conical member 17. Conical member 17
Is not provided, the main combustion air flows through the center line CL of the combustion cylinder 2.
In this case, the ejector effect is maximized and the carbonized gas is drawn in, but the main combustion air and the carbonized gas are not sufficiently mixed and burned without burning. It passes through the cylinder.

Also, contrary to FIGS. 1 and 3, the conical member 17
Is disposed such that the bottom of the conical member 17 is opposed to the opening 3a, the flow of the main combustion air is obstructed, the ejector effect is reduced, and the dry distillation gas from the dry distillation chamber 1 into the combustion cylinder 2 is removed. Is inhibited. On the other hand, by arranging the conical member 17 as described above, the main combustion air is
At the time of collision with the conical member 17, the flow velocity is temporarily reduced,
It rises while forming a vortex flow throughout the combustion cylinder.

The following effects can be obtained by the formation of the upward vortex flow. Sufficient mixing of the main combustion air with the carbonized gas and promotion of combustion: The main combustion air and the carbonized gas are sufficiently mixed and burned. Mixing of the main combustion air with the carbonized gas by uniforming the flow velocity distribution of the main combustion air in the horizontal cross section inside the cylinder of the combustion cylinder 2
Acceleration of combustion: The main combustion air changes its flow velocity distribution in the horizontal cross section inside the cylinder of the combustion cylinder 2 from a central flow along the center line CL of the combustion cylinder 2 to a uniform flow in the horizontal cross section inside the cylinder. Mixing and combustion of air and carbonization gas are promoted, and the residence time of the combustion gas in the combustion cylinder is lengthened, so that the combustion cylinder is heated effectively.

The effect of promoting the introduction of dry distillation gas by the ejector effect of the main combustion air: The conical member 17 is disposed such that the apex of the conical member 17 is opposed to the opening 3a. The effect of promoting the carbonization gas introduction by the ejector effect is exhibited, and the introduction of the carbonization gas from the carbonization chamber 1 into the combustion tube 2 is promoted. As a result, the throughput of the vertical incinerator per unit time can be improved.

As described above, in the present invention, due to the above-described arrangement of the conical member 17, during the main combustion, the main combustion air forms a vortex and is introduced into the combustion cylinder 2, and as a result, The mixing and combustion of the carbonized gas introduced into the combustion cylinder 2 and the main combustion air are promoted, complete combustion is completed in the lower part of the combustion cylinder, and the high-temperature region in the vertical direction in the combustion cylinder 2 becomes longer, It is possible to prevent the generation of dioxins and to improve the throughput per unit time of the vertical incinerator by promoting the introduction of the dry distillation gas from the dry distillation chamber 1 into the combustion tube 2 by the ejector effect of the main combustion air. it can.

In the vertical incinerator of the present invention,
As shown in FIG. 3 (b), it is more preferable to dispose a moving device 17a for the conical member 17 so that the above-mentioned conical member 17 can move in the vertical direction. This is for the following reason. That is, when the supply amount of the main combustion air decreases due to a decrease in the required processing amount per unit time of the vertical incinerator or the like, the linear velocity of the air at the opening 3a of the main combustion air supply pipe 3 decreases. However, the formation of the vortex flow is prevented.

For this reason, the conical member 17 is moved up and down in response to the change in the supply amount of the main combustion air, and the member 17 and the opening 3a are moved.
Is adjusted, the linear velocity of the air flowing through the gap between the opening 3a and the conical member 17 is adjusted, and a stable vortex flow with time can be formed. As shown in FIGS. 1 and 2, the dry distillation gas introduction grid 4 crosses the dry distillation chamber 1 below the above-mentioned cylinder inlet 2K _{2 and at} the lower part of the dry distillation chamber 1. It is arranged in the center of the plane (horizontal section) and in the vertical direction.

The dry distillation gas introduction grid 4 according to the present invention includes a plate having an opening, a curved plate having an opening, a rod, a pipe, a rod having a bend, a pipe having a bend, a protrusion, and the like.
The carbonization gas can be introduced from the carbonization chamber 1 into the combustion tube 2, and the incineration (incineration) in the carbonization chamber 1 is introduced into the gas flow path S formed by being surrounded by the carbonization gas introduction grid 4. The type of the grid is not limited as long as it can prevent intrusion.

The “grating plane” in the present invention means a plane formed by a grid. That is, for example, when the carbonization gas introduction lattice is formed by a plurality of rods, it means a surface including the plurality of rods in a common plane when the rods are regarded as lines, and the carbonization gas introduction lattice forms an opening. In the case of a plate-like lattice having the same, it means a surface surrounded by the plate surface. (Features of the vertical incinerator of the first invention :) The vertical incinerator of the present invention has the following excellent features (1) to (3).

(1) Acceleration of dry distillation gasification: According to the vertical incinerator of the present invention, first, the combustion cylinder 2 is quickly and rapidly heated by the high-temperature auxiliary combustion flame introduced from the auxiliary combustion device 7 into the combustion cylinder 2. It is sufficiently heated, and the radiant heat of the combustion tube 2 quickly starts gasification of the incinerated material (waste). The combustion flame of the carbonized gas itself further heats the combustion tube 2 to a higher temperature, and the radiant heat incinerates it. Dry distillation gasification of the product is further promoted.

(2) Stabilization of incineration: According to the vertical incinerator of the present invention, even when the temperature in the carbonization chamber 1 is reduced, the high temperature from the auxiliary combustion device by restarting the auxiliary combustion device 7 is obtained. By the auxiliary combustion flame, it is possible to carry out the dry distillation of the incinerated material without delay. (3) Promotion of combustion, prevention of generation of dioxins, and improvement of throughput per unit time of the incinerator:
According to the vertical incinerator of the present invention, as described above, by disposing the conical member 17 above the opening 3 a of the main combustion air supply pipe 3, the carbonized gas and the main combustion air are separated. Mixing and combustion are promoted, and the generation of dioxins can be prevented, and the throughput of the incinerator per unit time can be improved. [First preferred embodiment of the first invention:] In the present invention,
As shown in FIGS. 1 and 2, the center line of the gas flow path S formed in the vertical direction and surrounded by the lattice plane of the carbonization gas introduction lattice 4,
And arranged both upwardly open central auxiliary combustion flame inlet O ₁ in order to introduce an auxiliary combustion flame of the auxiliary combustion device 7 to the gas flow passage S is located on the center line CL of the combustion liner 2 Is preferred.

In the present invention, the opening 3a of the main combustion air supply pipe 3 is an upward opening, and the center of the opening 3a is located on the center line CL of the combustion cylinder 2. Is more preferable. This is because the effects (1) to (3) below can be obtained by adopting the above configuration, and it is possible to increase the incineration capacity of waste per unit time and unit time of the carbonization chamber. is there.

(1): Increasing the temperature of the incinerated material in the carbonization chamber and carbonizing gasification; combustion flame of the auxiliary combustion device 7 which rises in the gas passage S and the combustion cylinder 2 during auxiliary combustion (an auxiliary combustion flame) The concentration distribution and the velocity distribution in the cross section of the flow path become symmetrical distributions with respect to the center line CL of the combustion cylinder 2, and the temperature rise of the incineration material and the carbonization gasification opposed to the carbonization gas introduction grid 4 and the combustion cylinder 2 are performed. ,
This can be performed uniformly over the entire dry distillation chamber 1.

(2): Uniform carbonization gasification of the incinerated material in the carbonization chamber during main combustion; It is possible to uniformly gasify the incinerated material in the carbonization chamber 1 during main combustion. (3): Rapid incineration of waste (: incineration); (1) and (2) above
This makes it possible to quickly incinerate all the waste in the carbonization chamber 1. [Second Invention:] FIG. 4 shows an example of a vertical incinerator of the second invention in a longitudinal sectional view (a partial sectional view showing a longitudinal section of a carbonization chamber and an auxiliary combustion device), and FIG. , FIG. 4A
FIG.

[0036] 4, 5, 200 feeding tube, S ₁ feed auxiliary combustion flame is formed in a vertical direction surrounded by the outer peripheral surface of the feed tube 200 lattice planes of carbonization gas introducing grid 4 and feeding the auxiliary combustion flame Done,
The cross-sectional shape of the flow path is an annular dry distillation gas flow path, and other reference numerals indicate the same contents as those in FIGS. Incidentally, the flow path cross-sectional shape carbonization gas flow path S ₁ of the annular is a portion hatched by the dotted line in FIG. 5 (a).

In the vertical incinerator according to the second aspect of the present invention, as shown in FIGS. 4 and 5, the vertical incinerator is formed so as to be vertically surrounded by the lattice surface of the dry distillation gas introduction lattice 4 in FIGS. and the gas flow path S, the sheet tube 200 feeding vertically auxiliary combustion flame from the auxiliary combustion flame inlet O ₁ to the combustion cylinder 2 is provided. That is, in the vertical incinerator of the second aspect of the invention, the dry distillation gas flow channel cross section from carbonization gas introducing grid 4 is introduced into the carbonization gas flow path S ₁ of the annular, without mixing with the auxiliary combustion flame combustion vertical carbonization gas flow path formed in the outer peripheral surface of the feed tube 200 lattice planes of carbonization gas introducing grid 4 and feeding the auxiliary combustion flame (flow path cross section flow channel of annular) via the S ₁ It is introduced into the cylinder 2.

On the other hand, the auxiliary combustion flame from the auxiliary combustion flame inlet O ₁ rises in the auxiliary combustion flame feed cylinder 200 and is introduced directly into the combustion cylinder 2. In the second invention, the auxiliary combustion flame feed cylinder 200 is different from the auxiliary combustion flame feed cylinder 200 in that the height of the upper end opening of the auxiliary combustion flame feed cylinder 200 is the same as the height of the upper end of the opening of the carbonization gas introduction grid 4 or FIG. As shown in the figure, it is preferable to arrange the carbonization gas introduction grid 4 so as to be higher than the upper end of the opening.

Further, it is preferable that the distance h between the height of the upper end of the opening of the dry distillation gas introduction grid 4 and the height of the upper end of the auxiliary combustion flame feeding cylinder 200 satisfies the following expression (1). It is more preferable that the distance h satisfies the following expression (2). H ≧ h ≧ 10 mm (1) H ≧ h ≧ 20 mm (2) [In the formulas (1) and (2), H is the height of the upper end of the opening of the carbonization gas introduction grid 4 and the main combustion. The distance from the height of the upper end of the air supply pipe 3 is shown. The distance H is preferably about 50 to 100 mm.

This is because when the height of the opening of the auxiliary combustion flame feed cylinder 200 is lower than the upper end of the opening of the dry distillation gas introduction grid 4, the dry combustion gas is introduced into the combustion cylinder 2 by the auxiliary combustion flame feed cylinder 200. The effect of promoting introduction decreases, and conversely, the height of the opening is excessively high,
If h exceeds H, the vortex of the main combustion air is disturbed at the time of main combustion, which hinders mixing with the carbonization gas, resulting in incomplete combustion.

When the distance H is less than 50 mm,
Good vortex of main combustion air is not formed, conversely 100mm
If it exceeds, the thermal efficiency will decrease. (Method of Incineration of Waste by Vertical Incinerator of Second Invention :) The incineration of waste (incineration) by the vertical incinerator of the second invention is performed as follows.

First, after incinerated material is put into the distillation chamber 1,
The auxiliary combustion device 7 is started. The combustion flame from the auxiliary combustion device 7 (: auxiliary combustion flame) rises in the auxiliary combustion flame feeding cylinder 200, is directly introduced into the combustion cylinder 2, and is discharged from the chimney 90. The combustion tube 2 is heated by the auxiliary combustion flame, and the radiant heat and conduction heat transfer of the heated combustion tube 2 causes the carbonization chamber 1 to heat.
The incineration inside is heated and the incineration starts to dry distillation in an oxygen-free state.

The dry distillation gas generated by dry distillation of incinerated has a passage cross-section is introduced into the combustion cylinder 2 via the carbonization gas flow path S ₁ of the annular from carbonization gas introducing grid 4. on the other hand,
Prior to the generation of carbonized gas by heating and heating the combustion cylinder 2,
The combustion air blower 8 is started, and the main combustion air is supplied from the air supply opening 3a of the main combustion air supply pipe 3 to the combustion tube 2.
In the lower part of the inside.

The carbonization gas generated by carbonization of the incinerated material is combusted by the mixture of the high-temperature auxiliary combustion flame and the main combustion air, the main combustion starts, and the heating of the combustion cylinder 2 is continued by the combustion heat of the main combustion. Then, gasification of the incinerated material in the carbonization chamber 1 and burning of the carbonized gas, that is, incineration of the incinerated material are continuously performed. In the vertical incinerator of the present invention, it is possible to stop the auxiliary combustion of the auxiliary combustion device after the combustion of the mixed gas of the carbonization gas and the main combustion air following the auxiliary combustion, that is, after the main combustion starts. However, when the temperature in the carbonization chamber 1 decreases, the auxiliary combustion device 7 is restarted, and the auxiliary combustion flame from the auxiliary combustion device 7 causes the incineration (to be incinerated) to be carbonized and gasified. Combustion, that is, incineration of incinerated material can be performed quickly without delay.
