Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a small incinerator for incinerating general garbage, garbage and sludge discharged from general households, factories, recreational facilities, eating and drinking facilities and the like.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 43 and FIG.
Garbage and garbage discharged from households, factories, recreational facilities, eating and drinking facilities, etc., were put together in an incinerator using an incinerator such as No. 3, and were completely forcibly burned by a burner or the like. .

[0003]

However, recently, environmental standards have been extremely restricted not only for large incinerators owned by factory facilities and local governments, but also for small incinerators installed in homes and recreational facilities. However, it was very difficult to reduce the size of the incinerator.
Larger facilities can easily take measures for exhaust gas, combustion temperature, heat and temperature resistance, but the smaller the incinerator,
Such measures were difficult to take both technically and physically.

[0004] In each of the incinerators for which a patent has been registered,
As shown in FIGS. 43 and 44, unless the diameter of the cylindrical smoke exhaust chamber of the cyclone portion (secondary combustion chamber) is to some extent, the flame cannot rotate in the smoke exhaust chamber and cannot be completely burned. When the incinerator was downsized and the diameter of the smoke exhaust chamber was reduced, the rotating flame collided with the returning flame and was disturbed in the smoke exhaust chamber, so that it did not burn completely (January 1997) The second guideline of the Waste Management Law promulgated in Japan requires a new furnace to have a residence time of 2 sec and an incineration temperature of 850 ° C or higher, preferably 900 ° C or higher. ), There is a problem that miniaturization is very difficult.

Further, in general, generation of dioxins is controlled by incineration at high temperatures and rapid cooling of exhaust gas (at the time of incineration of wastes, sufficient residence time at high temperatures to completely oxidatively decompose dioxins or dioxin precursors such as benzene chloride). There is also a research result that it is necessary to incinerate by giving a temperature of 200 ° C. and to rapidly cool the combustion gas to 200 ° C. or less so as not to re-synthesize dioxins around 300 ° C. (to about 200 ° C. in about 1 second). It is said that it is necessary to perform rapid cooling when the incinerator is downsized.

Accordingly, the present invention provides a dioxin and the like which are problematic by maintaining a high temperature while maintaining a high temperature while the flame is extended for a long time without intersecting and colliding with the rotating flames in the flue gas chamber. It is an object of the present invention to provide a small-sized incinerator having a spiral structure capable of pyrolyzing harmful substances at a high temperature.

[0007]

According to the present invention, there is provided an ash receiving chamber having a bottom plate provided with a vent and a slide plate and an ash tray and an incinerator having a mounting plate. It is characterized by comprising an incineration section, a flue section having an air intake, a spiral flue, an exhaust port and a burner, and a cyclone section having a smoke exhaust chamber, a stacking chamber, a chimney, an air inlet, a blower, and an air duct. And a flue used in the spiral structure incinerator is a polygonal tubular body, and a spiral groove and a ridge are provided on an inner surface thereof. Configuration.

FIG. 1 shows a first embodiment of the spiral structure incinerator according to the present invention.
FIG. 2 is a front sectional view of a first embodiment of a spiral structure incinerator according to the present invention.

The helical incinerator 1 of this embodiment comprises an incinerator 2, a flue 5 and a cyclone 7. Incineration unit 2
Is divided into an incineration chamber 2a and an ash receiving chamber 3 by a cradled mounting plate 2b.

An ash tray 3a for receiving incinerated ash produced by completely burning the incinerated material 4 in the incinerator 2a is provided at the center of the ash receiving chamber 3, and a bottom plate 3b of the ash receiving chamber 3 has a slit as a vent. 3c, the opening of the ventilation hole 3c is adjusted by a slit-shaped slide plate 3d.
Can be adjusted to burn completely.

Since the combustion chamber 2a is always under a negative pressure by the blower 9, the mounting plate 2b and the ventilation holes 3 of the ash receiving chamber 3 are formed.
Fresh air can be introduced from c. Therefore, the intake amount of fresh air introduced by the slide plate 3d can be adjusted by the opening amount of the slide plate 3d.

When the incinerated material 4 in the incinerator 2a is ignited and burned by a heat source, the smoke containing dioxins and toxic gas passes through the unburned incinerated material, and the smoke itself is discharged. And the negative pressure in the incinerator 2 caused by the heat of the air and the blower 9.

Incidentally, the heat source is not shown in FIG.
Provided above or below the bottom plate 3b and the slide plate 3d of the ash receiving chamber 3, the temperature of the freshly sucked air introduced from the ventilation holes 3c is raised at a stretch, and the mounting plate 2b (so-called grate) is formed. It also plays a role in igniting the incineration material 4 placed above. The heat source itself is a heat source using a burner using gas, kerosene, heavy oil, or the like as a fuel, a heater using electricity or gas, heating using electromagnetic waves, a conductive heat source such as a nichrome wire, plasma, electric ignition, an electric heater, or the like.

The flue section 5 is composed of a flue chamber 5a, a collecting port 5b, a straight flue 5c, a spiral flue 5d, an outlet 5e and a burner 6. A burner 6 is attached to the straight flue 5c, and a spiral flue 5d is connected. The incinerator 2a and the flue gas chamber 7a are communicated with each other via a straight flue 5c and a spiral flue 5d.

Smoke containing dioxins and toxic gases generated by burning the incineration material 4 in the incineration chamber 2a flows into the straight flue 5c from the air collection port 5b. The smoke discharged through the straight flue 5 c is burned at a high temperature by the flame of the burner 6.

The flame 6a formed by burning the flue gas passes through the spiral flue 5d as a long flame 6a extending in the spiral flue 5d connected to the straight flue 5c, and the flue gas is discharged. Exhaust gas generated by the combustion is discharged from the spiral flue 5d to the flue gas chamber 7a together with the flame 6a.

The flame 6a is generated when the smoke is burned and when the smoke is blown by the blower 9.
In addition to the negative pressure condition a, the spiral structure of the spiral flue 5d
A longer extended flame 6a can be obtained. In addition, it is possible to burn the exhaust gas evenly for a long time by passing the exhaust gas through the flue, as compared with a conventional cyclone unit in which a burner is provided in the exhaust gas chamber.

The cyclone section 7 includes a smoke exhaust chamber 7a, a deposition chamber 7
b, a chimney 8, a blower 9 and a blower tube 10. Exhaust gas generated by the combustion of the flue gas is discharged from the discharge port 5e to the flue gas chamber 7a together with the flame 6a, and the flow of the flue gas generates a vortex in the flue gas chamber 7a.

The flame may remain from the discharge port 5e, so-called afterburner may be generated. And the smoke exhaust chamber 7a
Some of them continue burning, but when the incinerator is downsized, rotating flames may collide with each other and burn poorly. However, there is no problem because the flue gas is completely burnt in the flue chamber 5a of the flue section 5. That is, the spiral incinerator 1 of the present invention can be downsized.

Exhaust gas generated by completely combusting the flue gas rotates in the flue gas chamber 7a and is rapidly cooled, and fine dust and the like in the flue gas settles while rotating. Then, the settled fine dust accumulates in the accumulation chamber 7b.

Further, air is blown from an outlet 10a of a blower tube 10 connected to a blower 9 to an inlet 8a at a lower end of a chimney 8 provided at the center of the cylindrical exhaust chamber 7a. The compressed air blown out from the air outlet 10a to the air inlet 8a causes the smoke exhaust chamber 7a and the spiral flue 5
d, a negative pressure state also occurs in the direct flue 5c and the incineration chamber 2a.

The incinerator 1 is designed to have heat resistance, temperature resistance and fire resistance. For example, a three-layer structure for fire and heat resistance is adopted around the incinerator 2a, and the stacks 5a, 5c, 5c
Similar fire, heat and temperature resistance measures are taken for d and the surroundings forming the smoke exhaust chamber 7a. In particular, the temperature at which dioxins are not generated or the temperature at which dioxins can be decomposed is extremely high (it is said to be 1100 ° C. or higher). Therefore, it is unnecessary to take the above measures when implementing the present invention. It is important to be careful.

FIG. 3 shows a second embodiment of the spiral incinerator according to the present invention.
FIG. 4 is a plan sectional view of a spiral incinerator according to a second embodiment of the present invention. This incinerator 1a

Thus, the amount of ventilation can be adjusted so that the incinerated material 4 can be completely burned.

Since the combustion chamber 2a is forced to blow air from the blower 9 into the chimney 11a, the inside of the chimney chamber 11c is always in a negative pressure state, so that fresh air is supplied from the mounting plate 2c to the combustion chamber. 2a. The amount of fresh air to be introduced through the ventilation holes 3c of the bottom plate 3b can be adjusted by adjusting the degree of opening and closing of the slit-shaped slide plate 3d.

Then, the incinerated material 4 in the incineration chamber 2a is heated by the heat source.
When it is ignited and burned, smoke containing dioxins and toxic gas passes through the gap of the unburned incinerated material 4, passes through the ventilation hole 2f formed in the inner plate 2c, and emits smoke itself. And the air blown by the blower 9 causes a negative pressure state, so that the pressure rises and is sucked into the smoke exhaust chamber 11c.

Although the heat source is not shown in FIG. 8, it is provided above or below the bottom plate 3b and the slide plate 3d of the ash receiving chamber 3, so that the fresh suction air introduced from the vent hole 3c is heated at a stretch. Also, it plays a role of igniting the incineration material 4 mounted above the mounting plate 2b (so-called grate). The heat source itself uses a burner that uses gas, kerosene, heavy oil, or the like as a fuel, a heater that uses electricity or gas, heating using electromagnetic waves, a conductive heat source such as a nichrome wire, plasma, electric ignition, an electric heater, or the like.

The flue section 5 includes an air inlet 5b, a spiral flue 5d,

Smoke containing dioxins and toxic gas generated by burning the incineration material 4 in the incineration chamber 2a is introduced into the spiral flue 5d from the air collection port 5b, and is burned at high temperature by the flame of the burner 6. Let me do.

The flame 6a formed by burning the flue gas becomes a flame 6a elongated by the spiral structure, passes through the spiral flue 5d, and the flue gas generated by burning the flue gas together with the flame 6a It is discharged from the discharge port 5e to the chimney room 11c and is rapidly cooled.

The flame 6a has a spiral flue 5 in addition to the momentum when the flue gas is burned and the negative pressure by the blower 9.
Due to the spiral structure of d, the flame 6a can be extended longer. In addition, it is possible to burn the exhaust gas evenly for a long time by passing the exhaust gas through the flue, as compared with a conventional cyclone unit in which a burner is provided in the exhaust gas chamber.

The exhaust section 11 includes a chimney 11a, an inlet 11
b, a chimney room 11c, a blower 9 and a blower tube 10. Exhaust gas generated by the combustion of the exhaust gas is discharged from the spiral stack 5d to the chimney chamber 11c together with the flame 6a.

Air is blown from an air outlet 10a of a blower tube 10 connected to a blower 9 to an air inlet 11b at a lower end of a chimney 11a provided in the center of a cylindrical chimney chamber 11c. Then, the compressed air blown out from the outlet 10a to the inlet 11b causes a negative pressure state in the chimney chamber 11c, the spiral stack 5d and the incinerator 2a.

The incinerator 1c is provided with heat resistance, temperature resistance and fire resistance. For example, a three-layer structure for fire and heat resistance is adopted around the incineration chamber 2a, and the spiral stack 5d and the chimney chamber 11
Similar measures against fire, heat, and temperature are applied to the surroundings forming c. Particularly, since the temperature at which dioxins are not generated or the temperature at which dioxins can be decomposed is extremely high, it is important to take more care than necessary to take the above measures when practicing the present invention.

Since the combustion chamber 2a is always in a negative pressure state by the blower 9, the mounting plate 2b and the ventilation holes 3 of the ash receiving chamber 3 are formed.
Fresh air can be introduced from a. Therefore, the intake amount of fresh air introduced by the slide plate 3d can be adjusted by the opening amount of the slide plate 3d.

When the incinerated material 4 in the incineration chamber 2a is ignited and burned with a heat source, the smoke containing dioxins and toxic gas passes through the unburned incinerated material, and is discharged. It rises due to its own heat and the negative pressure of the blower 9.

Since the combustion chamber 15 a is always under a negative pressure by the blower 9, fresh air is introduced from the mounting plate 15 b and the ventilation holes 3 a of the ash receiving chamber 3. Therefore, the intake amount of fresh air introduced by the slide plate 3d can be adjusted by the opening amount of the slide plate 3d.

When the incinerated material 4 in the incineration chamber 15a is ignited and burned with a heat source, the smoke containing dioxins and toxic gas passes through the unburned incinerated material, and is discharged. It rises due to its own heat and the negative pressure of the blower 9.

Although the heat source is not shown in FIG. 13, it is provided above or below the bottom plate 3b and the slide plate 3d of the ash receiving chamber 3, so that the fresh suction air introduced from the vent hole 3c is heated at a stretch. Also, it plays a role of igniting the incineration material 4 placed above the mounting plate 15b (so-called grate).

The spiral flue 16c is provided spirally around the silo-shaped incinerator 15 so as to be wound upward from below. By making it wrapped, the incinerator can be reduced in size without taking up space. Unlike the incinerators of the first to fifth embodiments, the incinerator 15, the flue section 16, and the cyclone Separation with tower 18 greatly facilitates assembly and installation.

When the incinerator 14 is provided as an incinerator by storing each part in one box without dividing the incinerator 14 into parts, the spiral incinerator 16c is provided in a state of being wound around the incineration chamber 15a.

FIGS. 27 and 28 show the sixteenth embodiment, and FIGS.
30 and FIG. 30 show the seventeenth embodiment, and FIGS. 31 and 32 show the eighteenth embodiment.
Examples will be described below.

FIG. 27 is a front sectional view of a sixteenth embodiment of the spiral structure incinerator of the present invention, and FIG. 28 is a front sectional view of the sixteenth embodiment of the spiral structure incinerator of the present invention.

The spiral structure incinerator 19 of this embodiment is similar to the incinerator 1
5. It comprises a flue section 20 and a cyclone tower 18.
The incineration tower 15 is divided into an incineration chamber 15a and an ash receiving chamber 3 by a cage-like mounting plate 15b.

An ash tray 3a for receiving incinerated ash formed by completely burning the incinerated material 4 in the incineration chamber 15a is provided at the center of the ash receiving chamber 3, and a bottom plate 3b of the ash receiving chamber 3 has a ventilation hole as a slit. 3a is provided, and the degree of opening and closing of the ventilation holes 3a can be adjusted by the slit-shaped slide plate 3d, so that the incinerated material 4 can be adjusted to completely burn.

The combustion chamber 15a is provided with a blower 9 in a negative pressure state.
, The smoke exhaust chamber 18a is always in a negative pressure state.
Fresh air flows from the mounting plate 15b and the ventilation holes 3a of the ash receiving chamber 3. Therefore, it is possible to adjust the degree of intake of fresh air introduced by the slide plate 3d according to the degree of opening and closing of the slide plate 3d.

When the incinerated material 4 in the incineration chamber 15a is ignited and burned with a heat source, smoke containing dioxins and toxic gas passes through the unburned incinerated material, and the smoke The chimney chamber 11c is brought into a negative pressure state by the heat of the blower 9 and the heat of the
The incineration smoke inside is sucked into the smoke exhaust chamber 18a.

Although the heat source is not shown in FIG. 27, it is provided above or below the bottom plate 3b and the slide plate 3d of the ash receiving chamber 3, and the temperature of the fresh suction air introduced from the ventilation holes 3c is raised at a stretch. At the same time, it also plays a role in igniting the incineration material 4 placed above the mounting plate 15b (so-called grate). The heat source itself uses a burner that uses gas, kerosene, heavy oil, or the like as a fuel, a heater that uses electricity or gas, heating using electromagnetic waves, a conductive heat source such as a nichrome wire, plasma, electric ignition, an electric heater, or the like.

The flue section 20 includes an air inlet 20a, a flue 20
b, a discharge port 20c and a burner 21. The flue 20b and the burner 21 are connected to communicate the incineration chamber 15a and the smoke exhaust chamber 18a.

The flue 20 b is provided downward from the upper end of the side surface of the silo-shaped incinerator 15, and further provided upward so as to be folded back. The flue 20 b is connected to the upper end of the cyclone tower 18. Incinerator 15 and cyclone tower 18
The flue 20b is provided in a curved shape so as to be folded once, and the burner 21 is provided near the middle of the flue 20b.

In this embodiment, when the incinerator 15 and the cyclone tower are provided at separate positions, they can be connected to each other by the flue 20b. The flue 20 is wound around the incinerator 15 and the cyclone tower 18.
If b cannot be installed, it is important to provide the flue 20 b with as many curved portions as possible to increase the length of the flame generated by the burner 21.

Further, by dividing the incinerator 15, the flue section 20 and the cyclone tower 18, the assembly and installation of the incinerator 19 becomes very easy.

Smoke containing dioxins and toxic gas generated by burning the incineration material 4 in the incineration chamber 15a flows into the flue 20b from the air collection port 20a and is burned at high temperature by the flame of the burner 21. Can be

Then, the flame 21a formed by burning the flue gas becomes a flame 21a which is further extended due to the spiral structure provided in the flue 20b.
b, the flue gas produced by burning the flue gas is
A is discharged from the flue 20b to the flue gas chamber 18a together with a.

The flame 21a is not only provided with the momentum when the flue gas is burned and the negative pressure caused by the blower 9, but also with the flue 20a.
Due to the spiral structure b, the flame 21a can be extended longer. In addition, it is possible to burn the exhaust gas evenly for a long time by passing the exhaust gas through the flue, as compared with a conventional cyclone unit in which a burner is provided in the exhaust gas chamber.

The cyclone tower 18 includes a smoke exhaust chamber 18a, a deposition chamber 18b, a chimney 8, a blower 9, and a blower pipe 10. Exhaust gas generated by the combustion of the flue gas is discharged together with the flame 21a from the discharge port 20c to the flue gas chamber 18a, and the flow of the flue gas generates a vortex in the flue gas chamber 18a. At the same time, the exhaust gas is cooled rapidly.

The flame may remain from the discharge port 20c, so-called afterburner may be generated. And the smoke chamber 1
Some burners continue to burn in 8a, but when the incinerator is downsized, the rotating flames may collide with each other and not burn well. However, there is no problem since the flue gas is completely burned in the flue section 20. That is, the spiral incinerator 19 of the present invention can be reduced in size.

Exhaust gas generated by completely combusting the flue gas rotates in the flue gas chamber 18a, and fine dust and the like in the flue gas settles while rotating. The settled fine dust accumulates in the accumulation chamber 18b.

Further, air is blown from an outlet 10a of a blower tube 10 connected to a blower 9 to an inlet 8a at the lower end of a chimney 8 provided at the center of a cylindrical exhaust chamber 18a. Then, the compressed air blown out from the outlet 10a to the inlet 8a causes a negative pressure state in the smoke exhaust chamber 18a, the flue 20b, and the incineration chamber 15a.

The incinerator 19 is designed to have heat resistance, temperature resistance and fire resistance. For example, a three-layer structure for fire and heat resistance is employed around the incinerator 15a, and the flue 20b and the smoke exhaust
Similar measures against fire, heat, and temperature are also applied to the periphery forming a. Particularly, since the temperature at which dioxins are not generated or the temperature at which dioxins can be decomposed is extremely high, it is important to take more care than necessary to take the above measures when practicing the present invention.

The grooves 22a and the ridges 22b are not linear but are spirally provided as shown in FIG. This is because the flame generated inside the flue 22 becomes a spiral flame and the length of the flame becomes very long. As a result, the flue gas containing dioxins and toxic gas is generated inside the flue 22. It is capable of contacting the flame over long distances, completely burning the smoke and decomposing dioxins and toxic gases.

FIG. 35 is a cross sectional view of another embodiment of the flue used in the spiral structure incinerator according to the present invention. Main flue 22

In f, the shape of the tubular body is cylindrical, and a groove cut on the inner surface of the tubular body is provided with a curved groove 22a and a projection 22b.

By using a flue having a sectional shape as shown in FIGS. 33 to 38 in a spiral structure incinerator, dioxins and toxic gases can be more effectively decomposed with high heat.

FIG. 39 is a longitudinal sectional view of another embodiment of the burner used in the spiral structure incinerator according to the present invention. The burner which is used in the flue portion or the exhaust portion of the spiral incinerator according to the present invention shown in FIGS. 1 to 32 and generates the flame provided in the flue, the spiral flue and the straight flue is heated. A catalyst burner 23 using a catalyst may be provided instead.

The catalyst burner 23 includes a heating section 24, a nozzle 25, a blower 26a, an air inlet 26, and a catalyst section 2.
7 is comprised. The catalyst burner 23 is different from the burners shown in the first to eighteenth embodiments in that the burner flame is not provided in the tangential direction of the curved flue, and the flue 29, 29 is not provided. The flue gas combustion is made more efficient by providing a catalyst burner in the middle.

The heating section 24 heats the flue gas in the flue 29 by a burner 24b provided in a heating chamber 24a, and prepares a preparatory gas necessary for generating a temperature for burning dioxins and toxic gases at a high temperature. It is provided to generate heat. The burner 24b may be an electric heater or a stove.

Also, kerosene, heavy oil, gas, or the like is sprayed from the nozzle 25 onto the flue gas passing through the flue, and air rich in oxygen compressed by the blower 26a is blown out from the air inlet 26 into the flue gas. Generate a mixed gas. The mixed gas containing the flue gas is supplied to the heating unit 26.
Heated by

The catalyst section 27 includes a heat holding space 27a, a fan 27b, a mixer 28, a heat catalyst 28a, and a ceramics 28.
b. The mixed gas passes through the mixer 28, the heat catalyst 28a, and the ceramics 28b in a state where the surroundings are covered with the heat holding space 27a and kept warm.

When the mixed gas passes through the mixer 28,
As the mixed gas is burned, the temperature rises to the flash point of the mixed gas (about 200 ° C. or higher). And mixer 2
The mixed gas in the combustion state further mixed in 8 is subjected to catalytic combustion at about 400 ° C. by passing through the thermal catalyst 28a, and becomes a thermal catalyst high-temperature gas of about 800 ° C. to 1300 ° C. or more.

Next, the high temperature gas of the thermal catalyst passes through the ceramics 28b having the honeycomb structure, and passes through the flue. Exhaust gas discharged into the flue is a complete combustion gas containing fine dust, but harmful substances such as dioxins, toxic gases, NOx, SOx, and HCl are completely decomposed. Since it has been removed, it can be disposed of outside the incinerator. The dust contained in the exhaust gas may accumulate in the stacking chamber in the case of a helical incinerator in which a stacking chamber is provided in a flue gas chamber.

As shown in FIG. 39, a fan 27b is provided after the ceramics 28b. In each embodiment of the spiral structure incinerator according to the present invention, a blower 9 is provided.
Smoke exhaust gas and mixed gas are not mixed due to lack of negative pressure
8. Used when it is difficult to pass through the thermal catalyst 28a and the ceramics 28b. The fan 27b may be omitted.

As described above, by using the catalytic burner using a thermal catalyst instead of the burner provided in the flue, the spiral structure incinerator can be further reduced in size.

FIG. 40 is a perspective view of a filter provided in the flue of the spiral incinerator of the present invention, and FIG. 41 is a front sectional view of the spiral incinerator of the present invention when a filter and the like are provided.

It is generally known that the synthesis of dioxins at the time of exhaust gas cooling has the property of proceeding using dust in the exhaust gas as a catalyst. Therefore, the combustion smoke is retained at a high temperature by a flue burner to remove the dioxins. After the complete oxidative decomposition, it is a very effective means to remove the dust in the exhaust gas before cooling rapidly in the cyclone section.

Therefore, in this embodiment, as shown in FIG. 41, the filter 3 is provided after the burner provided in the flue.
1 is provided so as to remove dust. There is no doubt that this is an effective means in the spiral incinerator shown in FIGS. 1 to 32 as well as in this embodiment. Therefore, in the first to eighteenth embodiments shown in FIGS. 1 to 32, it is desirable to provide the filter 30 in the flue behind the burner.

As shown in FIG. 40, the filter 30 is obtained by forming quick lime 30a, slaked lime 30b, and activated carbon 30c into powder, granules, or sponge, and then forming a single plate into a layer. The plate-like layered quicklime 30a, slaked lime 3
0b and a filter that removes dust and toxic gas by passing exhaust gas through activated carbon 30c.

A bag filter may be provided at the same position in the flue instead of the filter 31. The bag filter is
A dust collecting device that collects fine powder with a filter bag or the like has the ability to collect even fine particles. It is commonly found in vacuum cleaners and the like. Since the temperature of the exhaust gas is very high, care must be taken in the material of the filter cloth bag. Especially when the temperature is too high for the filter cloth, spray water from the nozzle,
It is necessary to lower the temperature of the exhaust gas by injecting water and applying liquid.

Further, an electric dust collector may be provided after the filter or the bag filter provided in the flue. An electric dust collector is a device that collects fine particles on an electrode plate by electrostatic force, and is often provided in a chimney of a factory or the like. This is a machine that generates corona discharge in the machine, applies dust negatively, and collects dust at the positive electrode.

If dust removal is to be more effective, a wet dust collector or a spray tower may be provided instead of the filter or bag filter as a larger device for removing dust in exhaust gas. Wet dust collectors and spray towers not only remove dust in exhaust gases, but also play a role in rapidly cooling high-temperature exhaust gases.

The wet dust collector is a so-called scrubber which removes impurities while spraying or spraying water on dust-containing exhaust gas while lowering the temperature. It is used to wash out water-soluble components present in small amounts in the exhaust gas. The exhaust gas flow is made up of a cyclone scrubber that collects dust by colliding dust-containing exhaust gas that swirls inside the cylinder with droplets sprayed radially from the center of the cylinder, or a hollow synthetic resin such as a ping-pong ball. It is advisable to use a fluidized bed scrubber that collects dust in a liquid-suitable manner from the upper nozzle while floating.

The spray tower is a so-called cooling tower, which is a so-called cooling tower, which applies a scrubber which removes dust by dispersing a washing liquid from a large number of nozzles, dispersing droplets or liquid films or bubbles in a direction opposite to the dust-containing exhaust gas flow. Things. The longer the contact time between the droplets and the exhaust gas, the higher the removal rate of harmful gases and dust, and is often used in small incinerators.

As described above, the filters, bag filters, electric precipitators, wet precipitators, sprays, and the like are provided in the flue of the first to eighteenth embodiments of the spiral structure incinerator shown in FIGS. 1 to 32. Providing a tower is very effective.

In order to remove dust more effectively,
It is good to use a combination of two or more. For example, FIG.
It is preferable to provide a wet dust collector and a bag filter at the position of the filter 31 of the flue indicated by 1, or a cooling tower and a filter at the same position, or a wet dust collector and an electric dust collector.

FIG. 42 is a front sectional view of the spiral incinerator according to the present invention when a filter or the like is provided after the cyclone portion. Since there is a possibility that dust of several μm may be mixed in the gas discharged by implementing this spiral structure incinerator,
FIG. 42 shows a filter in which a filter 32 is provided after the cyclone section 18 for safety and an induction ventilator 33 and a chimney 34 are connected. The induction ventilator 33 is a fan that sucks combustion gas from the furnace and sends it to the chimney, and is generally called an induction fan.

Instead of the filter 32, as shown in FIG. 41, a bag filter, an electric dust collector, a wet dust collector, or a spray tower may be used. Alternatively, two or more of these may be combined and provided at the same position of the filter 32 shown in FIG.

For further safety, a filter is provided after the burner of the flue as shown in FIG. 41, and a filter is provided after the cyclone as shown in FIG. It is more effective to collect dust. Of course, a bag filter, an electric dust collector, a wet dust collector, a spray tower, or a combination of two or more of these may be used instead of the filter.

The incinerator, the spiral flue, the burner or the catalytic burner, the cyclone tower,
Filters, bag filters, electric dust collectors, wet dust collectors,
Spray towers, induction ventilators, and chimneys can be manufactured individually, and a spiral incinerator suitable for the installation location or incineration conditions can be assembled and installed by combining the individual devices. It is possible.

[0142]

The present invention has the following effects because it has the structure as described above. First, by providing a spiral flue and providing a spiral groove also on the inner surface of the flue, the flame is wound into a complete spiral and further spirally twisted, so in the flue Since the flame is completely well-equipped and the flame spreads very well to increase the combustion efficiency and maintain a high temperature for a long time, the unburned gas, dioxins, toxic gases, etc. can be completely decomposed, and smoke and smoke are extinguished. Exhibits the effect of odor.

Second, in the incinerator, if the diameter of the cyclone for smoke combustion is not larger than a certain size, the rotating flame hits the returning flame again and is disturbed inside the cyclone. Although the flame was not perfect throughout and it was very difficult to reduce the size of the incinerator, it is possible to increase the length of the flame by using the spiral flue and to reduce the size of the incinerator.

Third, the incinerator having the ability to decompose dioxins and toxic gases can be downsized.
Even if you do not collect a lot of garbage in one place like factories and entertainment facilities with large facilities, municipal incinerators, etc.
It is possible to completely incinerate without generating dioxins and toxic gases.
