By drawing air, the air can be sucked into the furnace and burned incredibly easily.

[III. Function of Incinerator of the present invention]

Functions and features of the incinerator (hereinafter also referred to as incinerator) of the present invention illustrated in FIGS. 1 to 4 are as follows.

① Arrangement of the radiator 3 of burner combustion gas:

In the distillation chamber (1), a radiator (3) of burner combustion gas is arranged.

(2) Arrange the dry gas inlet (7) at the outlet of the radiation container (3):

The outlet of the radiation cylinder 3 is also provided (arranged) with a dry gas inlet 7 at the inlet side of the combustion cylinder 4.

That is, in the present invention, unlike the conventional one, the radiation cylinder of the burner combustion gas which is a cylindrical body instead of the introduction lattice 30 of the distillation gas shown in FIG. 6 described above in the distillation chamber 1 ( 3) was placed, and furthermore, a dry gas inlet 7 into the combustion cylinder 4 was placed at the outlet of the radiation cylinder 3 and the inlet side of the combustion cylinder 4 as well.

As a result, according to the present invention, the following excellent effects are obtained.

① Effective use of burner combustion heat:

In the case where the inlet grating 30 of the dry gas is shown in FIG. 6, the gas containing the water of the incineration object is burned in the burner combustion flame through the inlet grating 30 of the dry gas in the initial stage of heating of the incineration object. Since it flows in, the temperature of a burner combustion flame will fall, and heating of the to-be-burned object by the radiant heat of a burner combustion flame is not performed quickly.

In contrast, according to the present invention, the burner combustion flame is maintained at a high temperature by disposing a radiation cylinder 3 that is a cylindrical body.

As a result, the radiation cylinder 3, which is a cylindrical body, becomes red during the combustion of the burner 2, and the heating of the burned object is started very quickly by the radiant heat of the high temperature burner combustion flame.

② Uniform heating in the furnace up and down direction:

In the case where the inlet grating 30 of the dry gas is shown in FIG. 6 described above, a part of the dry gas is combusted in the inlet grating portion of the dry gas, that is, in the lower part of the furnace, and accordingly, the temperature of the combustion flame in the combustion cylinder 4 Decreases, and the speed of heating, dry distillation and gasification of the incineration object on the upper part of the furnace due to the radiant heat of the combustion cylinder 4 decreases.

In contrast, according to the present invention, instead of the grating for introducing dry gas, the cylindrical radiation cylinder 3 is used, and the inlet port 7 of the dry fuel gas is provided between the radiation cylinder 3 and the combustion cylinder 4. By providing a), since combustion (partially combustion) of the dry gas in the vicinity of the furnace barrel does not occur, the heat of combustion of the dry gas can be effectively used for heating the burned object in the vicinity of the furnace cylinder.

That is, the radiant heat from the radiator 3 by the high temperature burner combustion flame is supplied to the burned-in object near the furnace radiant cylinder, and the radiant heat from the combustion cylinder 4 by the high-temperature combustion flame of all dry gas is the inside flame of the furnace. It is supplied to the incinerator near the communication, and the incinerator is heated uniformly in the up and down or left and right direction in the distillation chamber 1, and the dry and gasification of the incinerator of the whole furnace furnace advances rapidly.

③ Incineration by complete distillation and gasification:

Since the burner combustion flame is surrounded by the radiation cylinder 3, the burned combustion flame containing excess air does not intrude into the distillation chamber 1, and basically, the burned material of the burned object by complete distillation and gasification under anoxic conditions Incineration can be achieved.

As a result, low-temperature combustion of the burned material and dry gas by the mixed oxygen in the dry chamber 1 can be prevented, and the production of dioxins can be prevented.

④ Reduction of heat loss:

Since at least a part of the cylinder of the combustion cylinder 4 and the radiation cylinder 3 are all disposed in the distillation chamber 1, the radiant heat from the combustion cylinder 4 and the radiation cylinder 3 is dissipated out of the furnace, Radiant heat can be directly used to dry and gasify the object.

As a result, the heat loss to the outside of the furnace can be reduced, and the amount of auxiliary fuel such as kerosene used in the burner can be reduced quickly.

As mentioned above, although the function and the characteristic of the incinerator of this invention were demonstrated, according to the incinerator of the above-mentioned 1st-13th preferable example of this invention, the following effect is acquired further.

The inlet port 8 of the dry gas combustion gas for introducing air is arranged.

This is achieved by adjusting both the ratio of the burner combustion air and the burner fuel and the ratio of the dry gas burning air and the dry gas, so that the burner combustion gas temperature in the radiation chamber 3 and the burner in the combustion cylinder 4 are adjusted. Both the temperature of the mixed gas of the combustion gas and the dry gas combustion gas can be adjusted to the maximum temperature, respectively, and the radiant heat of the burner combustion gas and the dry gas combustion gas in the radiation cylinder 3 and the combustion cylinder 4 can be adjusted. This is because the radiant heat of can be utilized to the maximum in heating the incinerated object in the distillation chamber 1.

The gas temperature in the combustion cylinder 4 by indirect heat exchange of the gas in the combustion cylinder 4 and / or the gas in the flue 5 and the dry gas combustion air into the combustion cylinder 4, and preheating the dry gas combustion air. This is because the temperature becomes higher and the radiant heat from the combustion cylinder 4 can be utilized to the maximum.

(Incinerator of fifth preferred embodiment of the present invention and sixth preferred embodiment)

In the incinerators of the fifth preferred embodiment and the sixth preferred embodiment of the present invention, as illustrated in FIGS. 3 and 4, at least a portion of the combustion cylinder 4 and / or at least a portion of the chimney 5 are double piped. The inner cylinder of the double pipe is a combustion gas distribution channel in which the gas outlet 3a of the radiator 3 communicates with the gas flow path, and the air is introduced into the inlet 8 of the dry gas combustion air. the supply for dry distillation gas to the combustion air supply pipe (P _3), and with at least a portion of the conduit, a configuration having the distribution conduit (20) of the second of the air for combustion inside the dry distillation gas passage formed in the outer trough pipe inertia.

Speak to the barrel (3).

This configuration allows the radiant heat to be directly used for dry distillation and gasification of the incinerated object without the radiant heat from the combustion cylinder 4 and the radiant cylinder 3 being dissipated out of the furnace. It is possible to uniformly dry and gasify the incinerated shell in the cross-sectional direction, and as a result, it is possible to reduce the heat loss to the outside of the furnace and to reduce the amount of auxiliary fuel such as kerosene used in the burner and the burner. Because.

As described above, when the present invention is applied to a vertical incinerator, the length (height) h ₁ of the radiation cylinder 3 of the burner combustion gas and the length (height) h ₂ of the combustion cylinder 4 in the distillation chamber are represented by the following formula ( It is preferable to satisfy | fill 1) and (2), and it is more preferable to satisfy following formula (3) and (4) further.

In addition, the gas temperature at the exit side of the combustion cylinder is 800 ° C. or more in about 7 minutes after the burner ignition, and maintains a high temperature even after that, and it continues to stably dry and gasify the waste (burned material) and burn the dry gas. I found it possible to do.

As a result of this experiment, the dissipation gas emitted from the vertical incinerator of the present invention was lead-free, odorless, flameless, and harmless, and the residues in the incinerator were completely burned only by the carbonized product and the wire contained in the tire. Could.

Incidentally, the incineration throughput of the rubber per incinerator unit volume and unit time was increased by 20% compared to the incineration throughput of the rubber of the vertical incinerator in which the inlet lattice of the distillation gas was arranged at the lower center of the dry compartment in FIG. 6 described above.

This uses a radiation cylinder instead of the conventional lattice for introduction of the distillation gas, and installs an inlet for the distillation gas between the radiation cylinder and the combustion cylinder, so that radiant heat due to the high temperature burner combustion flame is reduced from the radiation cylinder to the lower part of the furnace. At the same time, radiant heat from combustion of dry gas is supplied from the combustion cylinder to the incinerator at the upper part of the furnace, and the incinerator is heated uniformly in the vertical direction in the dry chamber, so that the dry matter and gasification of the incinerator are rapidly progressed. I think it is because.

(Example 2)

In Example 1 mentioned above, since it turned out that the gas temperature of the exit side of the combustion cylinder 4 above the distillation chamber 1 is a high temperature of 800 degreeC or more, the internal volume shown in FIG. 3 mentioned above. Using this 500L vertical incinerator, tire incineration experiments were carried out under the same experimental conditions as in Example 1 above.

In this experiment, copy barrel 3, the length (height) h ₁ = 0.50 × H, open communication (4) the length _{(height) h 2 = 0.45 × H [} H of: the furnace height of the carbonization chamber (1) ] Vertical incinerator was used.

In this experiment, kerosene was used as the fuel of the burner 2.

As a result of this experiment, the incineration throughput of the rubber was increased by 10% compared to that of Example 1.

This dry distillation gas is at a temperature higher than the combustion flame (F _B) of the gas in the dry distillation, opened communication by preheating the combustion air for, is considered to be because the use of radiant heat by the combustion of the dry distillation gas more effectively.

(Example 3)

In Example 1, incineration experiments of rubber, waste plastic, wood chips, and tissues were conducted for three months.

As a result, the incineration process can be carried out smoothly at all times, and the incineration operation and the maintenance of the facility were extremely simple.

As described above, according to the present invention, the following excellent effects are obtained.

(1) Increase in incineration throughput:

Drying and gasification of wastes (burned materials) is started very quickly, and burned materials in the drying chamber are uniformly heated, and dryness and gasification of burned materials is rapidly progressed, thereby increasing the incineration unit volume and incineration throughput per unit time. You can.

(2) Incineration by complete distillation and gasification:

The burner combustion flame containing excess air is not thrown into the distillation chamber, and incineration of the incinerated object by basic distillation and gasification under anoxic conditions can be basically achieved, and generation of dioxins can be prevented.

(3) Reduction of Heat Loss:

The radiant heat can be directly used for dry distillation and gasification of the incinerator, without radiant heat from the combustion cylinder and the radiator being dissipated out of the furnace, resulting in less heat loss to the outside of the furnace. The amount of auxiliary fuel such as kerosene to be used can be reduced.

(4) Simplify the structure of the incinerator, simplify the incineration operation and repair the equipment:

Incinerator of the present invention is easy to structure, incineration operation and repair of equipment is also easy.

Industrial Applicability According to the present invention, it is possible to provide an incinerator which has a high efficiency of dry distillation and incineration of waste (fired incinerators), a simple incinerator structure, and an easy incineration operation and maintenance of equipment.
