[0002]

2. Description of the Related Art Conventionally, in the incineration of waste in an incinerator, highly flammable materials such as wood, paper and plastic are incinerated by the combustion of the waste itself, and low inflammable waste is treated as waste. Since it is difficult to incinerate only by burning itself, incineration is performed using a combustion device for heavy oil, gas and the like. Generally, a method is adopted in which waste put into an incinerator is ignited or continuously incinerated by a heavy oil (kerosene, gas) burner disposed on the side of the incinerator. Such incinerators often consist of a primary combustion chamber that directly burns waste and a secondary combustion chamber that reburns the exhaust gas generated in this primary combustion chamber with a flame radiated from a burner, and contains harmful components. We try to stay out of the incinerator as much as possible. The air required for incineration is
The fan is forced into the combustion chamber by a fan, or a hole for taking in air is provided so that the air naturally flows in accordance with combustion.

[0003]

Since the conventional incinerator is configured as described above, it is difficult to control the amount of air at the time of combustion, and the amount of air is insufficient, so that waste is not completely burned in the incinerator. In addition, there has been a problem that harmful components that pollute the environment, such as soot and smoke or dioxin that affects the human body, are released into the atmosphere.

Particularly, plastic waste has a problem that if the combustion temperature is relatively low (about 500 ° C.), a large amount of harmful by-products such as dioxin is generated, which adversely affects the environment. . On the other hand, in order to prevent this, sufficient air is supplied into the furnace, and the combustion gas is kept at a high temperature (1000
(° C. or higher), the generation of dioxin and the like can be suppressed, but there has been a problem that overheating and damage to the furnace wall, the grate, and the like are likely to occur, resulting in poor durability.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and can appropriately supply combustion air to completely burn waste and does not emit soot, smoke or environmental pollutants to the outside. In addition, an object of the present invention is to provide an incinerator which is excellent in durability without overheating in the furnace.

As shown in the figures, an incinerator 1 according to the present embodiment is formed in a hollow rectangular box shape, and has a primary combustion chamber 11 provided with a waste inlet 11a on the upper surface thereof, A secondary combustion chamber 12 disposed above the combustion chamber 11 and communicating with the primary combustion chamber 11; and a secondary combustion chamber 12 disposed on the side of the primary combustion chamber 11 and the secondary combustion chamber 12 and communicating with the secondary combustion chamber 12. The configuration includes a known cyclone 13 and a known chimney 14 in the form of a hollow cylinder disposed in communication with the cyclone 13.

The primary combustion chamber 11 is formed of a hollow, substantially rectangular box, and a grate 1 is provided on the bottom surface on which the waste 50 is placed.
1b is fixedly disposed, and a door 11c for closing the waste inlet 11a on each side wall and the upper surface is formed in a double structure made of a steel plate. In order to prevent overheating and burning in an intermediate portion of these double structures. This is a configuration in which water 11d is injected. A door 11c that closes the waste input port 11a is arranged to be openable and closable upward, and is configured to be opened and closed by a separately provided chain block (not shown). In addition, a plurality of air outlets 11e are provided at predetermined intervals in the longitudinal direction and vertically over a plurality of stages on two side walls parallel to the longitudinal direction of the primary combustion chamber 11. These air outlets 11e are arranged so that the arrangement positions on the opposite side walls are alternately shifted so that they do not face each other. Air blow pipes (not shown) are arranged in communication with each of the air outlets 11e for each of a plurality of stages, and the air blow pipes of each stage are provided with control valves (not shown) for adjusting the supply amount of compressed air. Omitted)
Through an air compressor (not shown) for supplying compressed air. Further, the primary combustion chamber 1
A primary burner 11f is disposed on a side wall on one end side in the longitudinal direction with the flame emission port facing horizontally.

The secondary combustion chamber 12 is formed of a substantially cylindrical body having a double structure made of a steel plate, is disposed so as to protrude upward from a part of the upper surface of the primary combustion chamber 11, and has a lower portion in the primary combustion chamber 11. It is the structure made to communicate with. Like the primary combustion chamber 11,
Water is injected into the middle part of the secondary structure of the secondary combustion chamber 12. In the secondary combustion chamber 12, an auxiliary combustion tube 12a formed of a cylindrical body having a large number of holes formed in a mesh shape and a large number of holes formed in a mesh shape with a disk supporting the auxiliary combustion tube 12a. Is provided. Further, the two secondary burners 12c direct the flame emission port horizontally into the secondary combustion chamber 12, and the emission direction is shifted from the center of the secondary combustion chamber 12 so as to be tangential to the auxiliary combustion cylinder 12a. It is arranged on the side wall of the secondary combustion chamber 12. On the other hand, at the inlet communicating with the primary combustion chamber 11 of the secondary combustion chamber 12, a substantially cylindrical sub-combustion cylinder 15 having a peripheral side wall with a large number of holes formed in a mesh shape protrudes into the primary combustion chamber 11. Is arranged.

Next, the incineration operation in the incinerator based on the above configuration will be described. As shown in FIG. 8, in the incineration process in the primary combustion chamber 11, first, waste 50 is put into the primary combustion chamber 11 from the waste input port 11a (step 1), the door 11c is closed, and the primary The flame is radiated from the flame radiating port of the burner 11f to ignite the waste 50 (step 2). Further, the air compressor is operated to supply compressed air into the primary combustion chamber 11 from the air outlet 11e. When the compressed air is supplied, by adjusting the control valve, the amount of air to be blown out is increased as the plurality of air outlets 11e become lower at the start of combustion so that the entire waste 50 can be ignited reliably (step). 3).

Changes in the flame color / flame temperature in the combustion chamber, or the amount and components of smoke discharged from the combustion chamber are detected by various sensors (not shown), and a control unit ( If it is determined that the entire waste 50 has shifted to a steady combustion state in which a flame is generated (not shown) (step 4), conversely, the air amount to be blown out is increased as the air outlet 11e becomes higher (step 4). 5), while supplying appropriate air to the burning waste 50 and continuously burning it, sufficient air is blown into the unburned gas and flying dust contained in the exhaust gas rising by the combustion to reburn. Thus, the amount of these flowing out to the secondary combustion chamber 12 is reduced.

Since the compressed air is locally blown out from the plurality of air outlets 11e, the entire combustion chamber does not have a uniform air supply state. In the lower layer, the amount of supplied air can be suppressed, and the excess air volume results in high combustion speed and high combustion temperature, while preventing the generation and outflow of harmful by-products such as dioxin Thus, damage due to overheating of the combustion chamber can be reliably prevented. In the present embodiment,
The control unit determines the transition from the combustion start state to the steady combustion state and changes the amount of air blown out from the air outlet at each stage. The control unit can adjust the amount of air blown out from each air blow-out port based on the combustion state to continuously control the combustion.

Due to the combustion in the primary combustion chamber 11,
The waste 50 leaves residual ash and becomes exhaust gas (including unburned gasified or vaporized components) and unburned dust, and is sent to the secondary combustion chamber 12. The exhaust gas and flying dust decrease the flow velocity by passing through each hole of the sub-combustion cylinder 15 on the way from the primary combustion chamber 11 to the secondary combustion chamber 12, and take a sufficient residence time to cause a sufficient residence time in the secondary combustion chamber 12. Combustion proceeds reliably. Further, when passing through the holes of the sub-combustion cylinder 15, the sub-combustion cylinder 15, which is heated by the heat in the primary combustion chamber 11, is partially burned by contact with the sub-combustion cylinder 15, and the unburned portion decreases.

Exhaust gas and flying dust entering the secondary combustion chamber 12 are regulated by the partition plate 12b, enter the auxiliary combustion cylinder 12a, and pass through a large number of holes provided on the side of the peripheral wall to form the secondary combustion chamber. It spouts into 12. The exhaust gas and the flying dust receive the flame emission from the secondary burner 12c in the secondary combustion chamber 12, and are re-burned together with the stirring, so that the unburned components are completely burned. Exhaust gas and fly ash generated by complete combustion are discharged from the secondary combustion chamber 12 and sent to the cyclone 13 where the exhaust gas and ash are separated. The ash falls and accumulates on the bottom of the cyclone 13 and is collectively discharged later.
Exhaust gas exits the central cylinder of cyclone 13 and goes into chimney 1
4 to the outside.

As described above, in the incinerator according to the present embodiment, the air outlets 11e are disposed in a plurality of stages vertically while shifting the air outlets 11e alternately in the horizontal direction on the opposite side wall of the primary combustion chamber 11. By making it possible to adjust the amount of compressed air to be blown up and down at each stage in accordance with the combustion state, after the entire waste 50 is securely ignited, an appropriate amount of air is supplied to the combustion temperature of the waste 50 itself. Not to become too high temperature, and it is also possible to blow sufficient air locally from the upper air outlets 11e to unburned gas and dust contained in the exhaust gas to completely burn at high combustion temperature. In addition to reducing the harmful components more effectively and reducing the amount of effluent flowing to the subsequent stage, the compressed air is locally blown and the primary combustion chamber 1
By not significantly affecting the air amount of the whole 1, overheating damage to the grate 11 b of the primary combustion chamber 11 and the like hardly occur, and the durability is excellent. In addition, an auxiliary combustion cylinder 12a and a partition plate 12b are provided in the secondary combustion chamber 12 and the primary combustion chamber 1
By arranging the sub-combustion cylinder 15 between the primary combustion chamber 12 and the secondary combustion chamber 12 and controlling the flow of the exhaust gas and the unburned components with these,
After prolonging the residence time of the exhaust gas and unburned components in the secondary combustion chamber 12, the exhaust gas and unburned components re-combust while being stirred in the secondary combustion chamber 12, and the unburned components in the exhaust gas Completely burns, and the amount of harmful components released to the outside can be significantly suppressed.

(Second Embodiment of the Present Invention) An incinerator according to a second embodiment of the present invention will be described with reference to FIG. FIG. 9 shows a schematic configuration diagram of main parts of an incinerator according to the present embodiment. As shown in FIG. 9, the incinerator 2 according to the present embodiment includes a primary combustion chamber 21, a secondary combustion chamber 22, a cyclone and a chimney (not shown), as in the first embodiment.

The secondary combustion chamber 22 is formed of a substantially cylindrical body having a double structure made of a steel plate, is disposed so as to protrude upward from a part of the upper surface of the primary combustion chamber 21, and has a lower portion inside the primary combustion chamber 21. It is the structure made to communicate with. Like the primary combustion chamber 21,
Water is injected into the intermediate portion of the double structure of the secondary combustion chamber 22. In the secondary combustion chamber 22, a large number of holes are formed in a mesh shape with an auxiliary combustion tube 22a formed of a cylindrical body having a large number of holes formed in a mesh shape and a disk supporting the auxiliary combustion tube 22a. Is provided. Furthermore, the two air supply fans 22c direct the outlet horizontally into the secondary combustion chamber 22, and shift the outlet direction from the center of the secondary combustion chamber 22 so as to be tangential to the auxiliary combustion cylinder 22a. It is arranged on the side wall of the next combustion chamber 22.

Next, the incineration operation in the incinerator based on the above configuration will be described. Similarly to the first embodiment, the waste 50 is supplied from the waste inlet 21a to the primary combustion chamber 2.
1, the door 21c is closed, the waste 50 is ignited, and compressed air is supplied into the primary combustion chamber 21 from the air outlet 21e. At the start of combustion, the supply of compressed air increases the amount of air to be blown out as the air outlets 21e of a plurality of stages become lower, and in the steady combustion state, increases the amount of air to blow out as the air outlet 21e becomes upper. The air is always appropriately supplied to the waste 50 and burned.

By the combustion in the primary combustion chamber 21,
The waste 50 leaves the residual ash and becomes exhaust gas (including unburned components that have been gasified or vaporized) and residual dust, and is sent to the secondary combustion chamber 22. Exhaust gas and flying dust entering the secondary combustion chamber 22 while maintaining the temperature are regulated by the partition plate 22b, enter the auxiliary combustion cylinder 22a, and pass through a large number of holes provided on the side of the peripheral wall to form the secondary exhaust gas. It is jetted into the combustion chamber 22. These exhaust gas and flying dust are supplied with compressed air in the secondary combustion chamber 22, are re-burned with stirring, and the unburned components are completely burned. Exhaust gas and fly ash generated by complete combustion are discharged from the secondary combustion chamber 22, sent to the cyclone as in the first embodiment, and separated into exhaust gas and ash,
Discharged separately.

As described above, in the incinerator according to the present embodiment, similarly to the first embodiment, in the primary combustion chamber 21, the combustion temperature of the waste 50 itself is set so as not to become too high. Overheating damage to the lattice 21b and the like is unlikely to occur, and
Harmful components can be more effectively reduced from exhaust gas,
Furthermore, by appropriately controlling the flow of the exhaust gas and the unburned components in the secondary combustion chamber 22 and reburning the unburned components only by blowing air without using the secondary burner, the harmful components can be reduced. It is possible to reduce the cost of the apparatus by omitting the secondary burner while maintaining the reduction of the emission to the apparatus.

The burned part will be locally burned with sufficient air, and the gasified combustion component in the blown part will be completely burned at a high temperature and a fast burning rate to generate no harmful components, and the incinerator The emission of such harmful components can be reduced as a whole, and the compressed air blowing does not significantly affect the air volume in the entire combustion chamber. This produces an effect that the room is hardly damaged by overheating and has excellent durability. Further, in the present invention, the air outlets are arranged so as to be staggered on the facing side walls so that the blown air does not interfere with each other, so that the compressed air forms a wide enough area of the air by the interference. Therefore, it is possible to increase the number of blowing points while maintaining the local blowing without excessively promoting the combustion of the waste, which has the effect of reducing harmful components more effectively. Further, in the present invention, the outlets are disposed in a plurality of stages vertically, and the blowing state of the compressed air can be different between the upper part and the lower part of the combustion chamber. Thus, the combustion state of the exhaust gas and the unburned gas that have risen to an optimum level can be adjusted to optimal states, respectively. This has the effect of reducing harmful components due to complete combustion and preventing overheating of the bottom and side walls of the combustion chamber. Further, in the present invention, by increasing the amount of compressed air blowout at the lower side at the start of combustion as compared to the upper side of the combustion chamber, and by increasing the amount at the upper side of the combustion chamber in the steady combustion state, the entire waste is reduced. After igniting properly, supply appropriate air to prevent the combustion temperature from becoming too high, and blow enough air to unburned gas and flying dust contained in exhaust gas to increase the combustion temperature. Thus, there is an effect that the reduction of harmful components and the prevention of overheating of the combustion chamber can be reliably achieved in a series of incineration processes without deteriorating ignitability. Further, in the present invention, a sub-combustion cylinder is disposed between the primary combustion chamber and the secondary combustion chamber, and the exhaust gas and unburned components are passed through the holes on the peripheral side wall of the sub-combustion cylinder, so that the passage resistance of the holes is reduced. As a result, the flow rate of the exhaust gas is reduced, so that the residence time of the exhaust gas and unburned components in the secondary combustion chamber can be lengthened, combustion can proceed reliably, and the sub-combustion cylinder glows with heat in the primary combustion chamber. As a result, the combustion of the unburned components can be promoted by the contact between the exhaust gas and the unburned components, and the harmful components can be further reduced from the discharged exhaust gas. Also,
