[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an incinerator for burning and treating combustion products such as waste wood, and more particularly to an incinerator having a primary combustion chamber and a secondary combustion chamber.

[0002]

2. Description of the Related Art Conventionally, as this kind of incinerator, for example, one disclosed in Japanese Utility Model Laid-Open No. 5-25131 is known. This is, as shown in FIGS. 10 and 11,
A primary combustion chamber 1 and a secondary combustion chamber 2 provided adjacent to the primary combustion chamber 1 are provided. The primary combustion chamber 1 includes an openable / closable opening 3 provided on a side portion to receive a combustible material such as waste wood, a storage unit 4 for storing the combustible material input from the opening 3, and a storage unit 4. The primary combustion unit 5 is provided below the storage unit 4 and primarily burns the combustion material stored in the storage unit 4, and an outside air introduction unit 6 that introduces outside air to the primary combustion unit 5. Reference numeral 5a denotes a grate provided below the primary combustion section 5 to receive a combustion substance. The secondary combustion chamber 2 has a communication port 7 that communicates with the primary combustion section 5 of the primary combustion chamber 1, and a secondary combustion section 8 that performs secondary combustion of the combustion gas from the primary combustion chamber 1, and a secondary combustion section 8. And a chimney 9 erected on the upper side.

[0003] When burning the burned material such as waste wood, the opening 3 is opened and the burned material is put into the storage section 4.
When an appropriate amount has been charged, the opening 3 is closed and the primary combustion section 5 is closed.
Ignites the combustion material. As a result, outside air is introduced from the outside air introduction section 6 and combustion is performed in the primary combustion section 5, and combustion gas in the primary combustion section 5 flows into the secondary combustion chamber 2 through the communication passage 7, and Due to the heat of combustion in the combustion section 5, the storage section 4
Combustion gas in the primary combustion section 5
And flows into the secondary combustion chamber 2 through the communication passage 7. Then, these gases are supplied to the secondary combustion section 8.
It is burned further.

[0004]

By the way, in this conventional incinerator, in the primary combustion section 5, the combustion material is put on the grate 5a and burned. There is a space between them and the density is coarse, so
It cannot be said that the heat volume is always sufficient, and the carbonization efficiency in the storage chamber 4 and the combustion efficiency in the secondary combustion section 8 are not always sufficient, and further improvement in carbonization efficiency and combustion efficiency is desired. There was a fact. Further, the capacity of the accommodation portion of the primary combustion chamber 1 is not always sufficient, and the opening 3
Is located on the side of the storage chamber 4, so that there is also a problem that it is difficult to put the combustion material into the storage section 4. The present invention has been made in view of such a problem, and improves the carbonization efficiency and the combustion efficiency by increasing the heat volume in the primary combustion section of the primary combustion chamber, and also minimizes the capacity of the storage section. It is an object of the present invention to provide an incinerator in which the treatment efficiency is improved by increasing the size of the incinerator.

[0005]

The technical means of the present invention for solving such a problem includes a primary combustion chamber and a secondary combustion chamber provided adjacent to the primary combustion chamber. The chamber is provided with an openable / closable opening into which a combustible material such as waste wood is charged, a storage portion in which the combustible material input through the opening is stored, and a storage portion provided below the storage portion. A primary combustion section for primary combustion of the stored combustion material; and an outside air introduction section for introducing outside air to the primary combustion section. The secondary combustion chamber communicates with the primary combustion section of the primary combustion chamber. An incinerator comprising a secondary combustion section having a communication port for performing secondary combustion of the combustion gas from the primary combustion chamber, and a chimney which communicates with the secondary combustion section and is provided on the upper side. The storage section in which the combustion material of the primary combustion chamber is stored has a cross-sectional area from the upper side to the lower side. Only to have a configuration which is formed in the funnel-shaped so as to gradually reduce.

[0006] When the incinerator having this configuration burns the burning material, an opening is opened, and the burning material such as waste wood is introduced into the storage portion of the primary combustion chamber through the opening. In this case, since the storage portion is formed in a hopper shape, the area of the opening can be made larger than in the case where the storage portion is straight, and the combustion material can be easily thrown in. By this charging, the combustion products are stored in the storage unit and reach the primary combustion unit, where they are packed. Then, when an appropriate amount is charged, the opening is closed, and the combustion material is ignited in the primary combustion section. The combustion products are burned by air from the outside air introduction section of the primary combustion chamber. As combustion progresses, in the primary combustion section, the burned material burns red, and a so-called “occurrence” of the burned material occurs,
Combustion in the primary combustion section is stabilized. As a result, the combustion gas in the primary combustion section flows into the secondary combustion chamber through the communication passage, and the combustion heat in the primary combustion section causes the combustion products in the storage section to be carbonized. The fuel is combusted in the section and flows into the secondary combustion chamber through the communication passage. Then, these gases are further combusted in the secondary combustion section.

[0007] In this combustion, the combustibles are gradually burned, but the accommodation portion of the primary combustion chamber is formed in a hopper shape such that the cross-sectional area thereof is gradually reduced from the upper side to the lower side. The load from above largely acts on the combustion material in the primary combustion portion, and the combustion material in the primary combustion portion is condensed. Therefore, the density of the combustion material increases. And the heat volume is increased as compared with the prior art. As a result, the dry distillation efficiency in the storage chamber and the combustion efficiency in the secondary combustion chamber are improved.

[0008] If necessary, the opening of the primary combustion chamber is formed at the upper end of the accommodating portion and opened upward, a door that moves horizontally to open and close the opening, And a support mechanism for supporting the movable member in the horizontal direction. Since the opening is open at the top, the burnable material can be easily put in as compared with the horizontal opening, and the workability of charging the burned material can be greatly improved. In this case, the support mechanism includes a wheel rotatably provided on the door, and a rail provided on the housing portion side and rolling the wheel, and the rail is projected outward of the housing portion. It is effective that all the openings can be opened when the door is opened. As a result, the entire opening can be opened when the door is opened, so that the opening can be widened. As a result, the combustible can be easily put into the storage section, and the workability of charging the combustible can be greatly improved. Can be improved. Further, since the door can be opened and closed by rolling the wheel on the rail, the operability is extremely improved.

Further, a gap adjusting mechanism formed between the door and the opening and capable of adjusting the width of a gap which allows air to flow into the housing portion is provided as required. Since the amount of air to the storage section can also be adjusted, the degree of freedom of air adjustment is increased, so that optimal combustion is easily obtained as compared with the closed type. It is needless to say that the door can be closed so as to eliminate the gap. Further, if necessary, the outside air introduction section of the primary combustion chamber may be provided with an air chamber provided adjacent to the primary combustion section, and an air port provided in the air chamber and capable of introducing outside air into the inside and having an adjustable opening. And a supply port through which the primary combustion section communicates with the air chamber to supply air from the air chamber to the primary combustion section. Since the air warmed in the air chamber can be supplied from the supply port to the primary combustion section, the combustion efficiency can be improved as much as the air can be heated.
Furthermore, the primary combustion chamber is provided with an air port capable of introducing air and adjusting the opening in the primary combustion section. In addition to the outside air introduction section, the amount of air can be adjusted also at this air port, and the degree of freedom in adjusting the air is increased, so that optimal combustion is easily obtained.

If necessary, an air passage which can be heated by the heat of the chimney is provided outside the intermediate portion of the chimney, the inlet of the air passage is open to the outside air, and the outlet of the air passage is connected to the primary combustion chamber. It is configured to be open to the accommodation section. Air is also supplied from the air passage, but since the air is heated by the heat of the chimney, the air heated in the air chamber will be supplied to the primary combustion section, and as much as the air is heated, The combustion efficiency is improved. Further, if necessary, an oil pipe through which oil can flow out is provided in the primary combustion portion of the primary combustion chamber. Immediately after ignition or the like, kerosene or the like can be supplied as a combustion aid to promote combustion, and the start-up to a steady state can be performed reliably and promptly. Further, during combustion, waste oil or the like can be supplied and burned, which is extremely convenient.

Further, if necessary, the secondary combustion section of the secondary combustion chamber is provided with an air introduction section through which outside air can be introduced. In addition to the outside air introduction section, the air introduction section can also adjust the amount of air, increasing the degree of freedom in adjusting the air, and thus making it easier to obtain optimal combustion.
In this case, the air introduction section is provided with a through hole provided in a wall of the secondary combustion chamber, a cover chamber covering the through hole, and an air opening provided in the cover chamber and capable of introducing air into the inside and adjusting the opening degree. It is effective to provide a possible air port and a shielding plate provided in the covering chamber and facing the through hole. This allows the air to stay in the cover room,
Since the shield plate is provided, the air can be bypassed and flow into the secondary combustion chamber, so that the air can be heated, the decrease in combustion due to cool air is suppressed, and the combustion efficiency is improved.

[0012] If necessary, an opening variable mechanism for changing the opening of the communication port of the secondary combustion chamber is provided. As the combustion of the combustion material progresses and the amount of the combustion material in the storage unit decreases, the amount of “Oki” in the primary combustion unit also decreases, but in such a case, by the opening degree variable mechanism, What is necessary is just to make the opening degree of the communication port of a secondary combustion chamber small. Therefore, the amount of combustible gas in the secondary combustion chamber can be adjusted, and appropriate combustion can be performed in accordance with the amount of the combustible, thereby improving the combustion efficiency. Furthermore, if necessary, the lower side of the chimney of the secondary combustion chamber faces the secondary combustion section, and a mesh body through which exhaust gas can pass is provided at the lower end of the chimney. It is configured to enable combustion. The combustion in the reticulated body and the lower end of the chimney is performed, and the reticulated body performs a catalytic action, so that the combustion in the secondary combustion part is further promoted.

Further, if necessary, a water tank configured as a wall portion of the secondary combustion chamber and containing water is provided outside the secondary combustion chamber at one end as a water inlet and the other end as a water outlet. In addition, a water heating pipe spirally wound and stored in the water tank and heated by the water tank is provided. By the heat exchange of the water heating tube, cold water can be easily obtained as hot water, and the heat can be effectively used. Further, if necessary, a water tank heated by the secondary combustion chamber is provided, and one end is opened at an upper portion of the water tank, and the other end is opened at an intermediate portion of the chimney. It has a configuration in which a steam ejection pipe for ejecting the gas into the inside is provided. Thereby, the inside of the chimney is cooled to prevent excessive heating, and the air and the combustion gas are well mixed to further promote the combustion, so that the combustion efficiency is extremely improved. Further, if necessary, a water tank that can be heated by the heat of the chimney is provided outside the intermediate portion of the chimney, and the water tank passes through the inside of the chimney to reach the lower end of the chimney and is generated in the water tank. A steam injection pipe for injecting the obtained steam to the lower end of the chimney is provided. As a result, the steam injection pipe is heated in the chimney, so that the heating steam is injected from the steam injection pipe, so that the air and the combustion gas are well mixed, the combustion is further promoted, and the combustion efficiency is extremely improved. . In this case, it is effective that a plurality of the steam injection pipes are provided, and the distal end of the steam injection pipe is bent obliquely so that steam is injected along the circumferential direction of the chimney. Since a swirl flow can be generated in the chimney, the mixing of oxygen and gas can be surely promoted, combustion can be further promoted, and combustion efficiency can be improved.

Further, if necessary, a resin decomposer for decomposing resins such as waste plastics is provided in the secondary combustion chamber, and the resin decomposer is disposed in the secondary combustion section and externally provided. A metal resin storage section having a resin input port that can be opened and closed, an exhaust pipe piped to the resin storage section to exhaust gas generated from the resin, and the secondary combustion chamber And a processing unit connected to the exhaust pipe and configured to process gas generated in the resin storage unit. Thereby, the resin stored in the resin storage section in a sealed state is thermally decomposed by the heat of the secondary combustion section, and generates gas. The gas flows into the processing unit through the exhaust pipe and is processed. As a result, the resin can be treated without directly burning it, thereby suppressing the generation of harmful substances.
In this case, it is effective that the processing unit is configured by a tank in which water is put. Since the treatment can be performed with water, the treatment is facilitated.

Therefore, when the incinerator according to this embodiment burns the combustible material W, the following is performed. Now, a description will be given of the case where the burned material W is, for example, waste wood that is generated when a building is broken. The water tank 41 and the water tank 60 are filled with water in advance. First, the door 18 is opened, and a combustible material W made of waste wood is put into the storage portion of the primary combustion chamber 10 through the opening 17 using a shovel loader or the like. In this case, the rail 22 is provided so as to protrude out of the housing portion 14, and the door 18 fully opens the opening 17 when the door is opened, so that the opening 17 is widened. It can be placed in the section 14 to facilitate storage. Further, since the opening 17 is open at the top, it can be easily inserted as compared with the conventional horizontal opening. In addition, the accommodation unit 14
Is formed in the shape of a hopper, so that the area of the opening 17 can be made larger than in the conventional straight case, and in this regard, the combustion material W can be easily introduced. By this charging, the combustion products W are stored in the storage section 14 and reach the bottom of the primary combustion section 15 and are packed. If there is any resin such as waste plastic, it is put in the resin storage section 72 of the resin decomposition device 70.

Then, when an appropriate amount is introduced, the opening 1
Close 3. In this case, the door 18 is closed, but the wheels 21 of the door 18 roll on the rails 22, so that the door 18 can be easily closed. If the left and right doors 18 are closed, the left and right doors 18
Connect and lock. In this state, the door 35 of the air port 34 of the primary combustion chamber 10 is opened, and the primary combustion section 15 is opened by using a combustion aid such as sawdust impregnated with kerosene.
Ignites the combustion material W. In this case, if kerosene or the like is allowed to flow out of the oil pipeline 38 to the primary combustion section 15, combustion in the early stage of ignition can be promoted. Then, the gap adjusting mechanism 23 of the opening 13 of the primary combustion chamber 10 and the outside air introduction unit 1
6. The opening of the air port 34 and the first and second air introduction portions 46 and 47 of the secondary combustion chamber 40 are adjusted to adjust the air amount to promote combustion. In the gap adjusting mechanism 23, the bolts 28 are appropriately loosened and tightened, so that the bracket 2
The door 18 is moved up and down with respect to 4, the width of the gap e between the door 18 and the opening 17 is adjusted, and the amount of air to the storage section 14 is adjusted. In this case, since the amount of air to the accommodating portion 14 can also be adjusted, the degree of freedom of air adjustment is increased, and therefore, it is possible to easily obtain optimum combustion as compared with the conventional closed type.

As the combustion proceeds, the burned material W burns red in the primary combustion section 15 to generate a so-called “occurrence” of the burned substance W, and the combustion in the primary combustion section 15 becomes steady. As a result, the combustion gas in the primary combustion section 15 flows into the secondary combustion chamber 40 through the communication port 42, and the combustion heat in the primary combustion section 15 causes the combustion products W in the storage section 14 to be carbonized.
The carbonized gas is also burned in the primary combustion section 15 and flows into the secondary combustion chamber 40 through the communication port 42. Then, these gases are further combusted in the secondary combustion section 43. In this case, outside air is introduced from the outside air introduction unit 16. Since the outside air introduction unit 16 includes the air chamber 30, the air warmed in the air chamber 30 is supplied from the supply port 32 to the primary combustion unit 15. Therefore, the combustion efficiency is improved as much as the air is heated. Further, air is also supplied from the air passage 37, but the air passage 37 is provided outside the intermediate portion of the chimney 44 and the air is heated by the heat of the chimney 44. Since the air is supplied to the combustion section 15, the combustion efficiency is improved by the amount of heating the air.

Furthermore, in the secondary combustion chamber 40, air is also supplied to the secondary combustion section 43 from the first and second air introduction sections 46 and 47.
Since the shield plate 47d is provided in the inner combustion chamber 7b, the air is stopped in the cover chamber 47b, so that the air is heated even slightly, and the air flows into the secondary combustion chamber 40 by bypassing the shield plate 47d. Therefore, a decrease in combustion due to cool air is suppressed, and also in this point, the combustion efficiency is improved due to the heating of the air. Further, the lower side of the chimney 44 of the secondary combustion chamber 40 faces the inside of the secondary combustion section 43, and the lower end of the chimney 44 is provided with a mesh body 56 through which exhaust gas can pass. Since combustion is performed in the lower end portion of 44 and the reticulated body 56 acts as a catalyst, combustion in the secondary combustion section 43 is further promoted.

In this combustion, the combustion material W is gradually burned, and the accommodating portion 14 of the primary combustion chamber 10 is formed in a hopper shape such that the cross-sectional area thereof gradually decreases from the upper side to the lower side. The combustion product W of the primary combustion unit 15
The load from the upper part acts greatly to condense the combustible material W in the primary combustion section 15, so that the density of the combustible material W increases, so that the so-called “Oki” density also increases. The heat volume is increased. As a result, the dry distillation efficiency in the storage chamber and the combustion efficiency in the secondary combustion chamber 40 are improved. That is, since the density of so-called "Oki" is high, the temperature in the secondary combustion chamber becomes high, and
Combustion and thermal decomposition of organic gas are promoted extremely well, the function of mineralizing harmful organic gas such as dioxin is greatly improved, and the situation of being exhausted from the chimney 44 or remaining in residual ash is reliably prevented, It will be extremely useful. According to experiments by the applicant, generation of harmful organic gases such as dioxin was hardly recognized.

When the combustion proceeds and the temperature of the entire incinerator rises, the water in the water tank 41 and the water tank 60 boils. As a result, first, the steam in the water tank 41 is ejected from the steam ejection pipe 58 to an intermediate portion of the chimney 44. Therefore, cooling is performed to prevent excessive heating, and the air and the combustion gas are well mixed to further promote the combustion, so that the combustion efficiency is extremely improved. Further, the steam of the water tank 60 is injected at the lower end of the chimney 44 through the steam injection pipe 61. In this case, the steam injection pipe 61 is connected to the chimney 44
Since the steam is heated through the inside, the steam becomes the heated steam and is injected. Therefore, the air and the combustion gas are well mixed by the injected heating steam, and the combustion is further promoted.
The combustion efficiency becomes extremely good. In this case, the steam injection pipe 6
Since the tip of 1 is bent obliquely so that steam is injected along the circumferential direction of the chimney 44, the mixing of oxygen and gas can be surely promoted, and the combustion efficiency can be further improved. Can be That is, even by the heating steam injected from the steam injection pipe 61, the combustion and thermal decomposition of the organic gas in the secondary combustion chamber 40 are promoted extremely well, and the function of mineralizing harmful organic gas such as dioxin is greatly improved. It will improve. Further, when water flows through the water heating pipe 57 due to the boiling of the water in the water tank 41, heat is exchanged with the water in the water tank 41 in the water heating pipe 57, so that hot water can be obtained. Therefore, it is possible to easily obtain cold water as warm water, and it is possible to effectively use heat.

Next, the operation of the resin decomposition apparatus 70 will be described. As shown in FIG. 9, the resin stored in the resin storage section 72 in a sealed state is thermally decomposed by the heat of the secondary combustion section 43 to generate gas. The gas flows into the processing unit 74 through the exhaust pipe 73 and is processed. Since water is contained in the processing section 74, a gas reacts with water or a component that melts the gas is taken into the water. For example, chlorine gas reacts with water to form hydrochloric acid (HCl). The gas after the reaction is discharged into the storage section 14 of the primary combustion chamber 10 through the discharge pipe 76, and is further decomposed by combustion in the primary combustion section 15. Further, the water in the tank 75 may be appropriately taken out and fresh water may be supplied. Further, the decomposed residue remaining in the resin container 72 may be removed later and burned in the primary combustion chamber 10.

Then, as the combustion of the combustibles W proceeds and the amount of the combustibles W in the storage section 14 decreases, the amount of “Oki” in the primary combustion section 15 also decreases. The opening degree of the communication port 42 of the secondary combustion chamber 40 may be reduced by moving the shutter 51 by the opening degree variable mechanism 50. Therefore, the amount of combustible gas in the secondary combustion chamber 40 can be adjusted, and appropriate combustion can be performed in accordance with the amount of the combustion material W, so that the combustion efficiency can be improved. During the combustion, the gap adjusting mechanism 23 of the opening 13 of the primary combustion chamber 10 is used.
The opening degree of the outside air introduction part 16, the air port part 34, and the first and second air introduction parts 46 and 47 of the secondary combustion chamber 40 is adjusted to adjust the amount of air to promote combustion.
