Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary drum type incinerator which incinerates wastes from general companies, factories, etc. efficiently and with low pollution. Particularly, flame retardants such as kitchen garbage are extremely efficient. It is also characterized in that it can be incinerated with low pollution.

[0002]

2. Description of the Related Art Conventionally, generally used incinerators are mainly metal incinerators with a chimney. Even if it looks like the outside is completely burned, things such as high-moisture contents and heavy-humid contents often cannot be completely incinerated because the core remains unburned. The slag increased the amount of incinerated waste and was an obstacle to cleaning.

Further, in the case of the conventional incinerator, it is necessary to clean and remove the incineration slag or ash every time or every time a certain amount of ash is accumulated, otherwise there is a drawback that the combustion efficiency is remarkably deteriorated. The result was defeated for the purpose of treating the waste without much effort.

Further, there is a problem in terms of pollution, such as smoke from the chimney, which emits smoke containing harmful substances, due to incomplete combustion such as the unburned residue as described above.

Therefore, the applicant previously filed Japanese Patent Application No. 3-6800.

EXAMPLE An example of the present invention will now be described with reference to the drawings. In the rotary drum incinerator of the present invention, the cylindrical outer drum a ₁ and the outer drum a ₁ are set around the same center line. cylindrical mesh drum a ₂ having at intervals, and with a 3 drum cylindrical mesh drum a ₃ equipped at a set interval polymerization integrally provided net-drum a _2, each drum A combustion drum A in which a feed plate 1 which is angled so as to form a substantially spiral shape on the inner surface is established and fixed, a rotary drive mechanism B for driving the combustion drum A to rotate at a controlled speed, and a waste drum net a.
₂ , a hopper C for charging into ₂ and a hopper D for charging the flame-retardant material into the mesh drum a ₃ , and a smoke exhausting means E for smoke and combustion gas,
It is composed of a combustion slag and an ash discharging means F.

In the above, the combustion drum A is a cylindrical drum drum a made of a metal mesh or a perforated plate in which a large number of small holes are formed in the metal plate inside a cylindrical outer drum a ₁ made of a metal plate.
₂ is inserted into the mesh drum a ₂ , and a cylindrical mesh drum a ₃ made of a wire mesh or a perforated plate in which a large number of small holes are formed in a metal plate is inserted into each drum a ₁ , a. ₂ and a ₃ are integrally connected to each other with a stay 2 or the like at a set interval.

However, the combustion drum A is installed on the base 3 so as to be rotatable in a fixed position, and the hoppers C and D are provided at the inlet sides of the mesh drums a ₂ and a ₃ of the combustion drum A, and the combustion drum A is provided. A smoke exhausting means E including a smoke circulation chamber 4, a partition plate 5, and a chimney 6, and an exhausting means F including an exhaust port 7, an adjusting door 8, a combustion slag, an ash receiving box 9, and the like are provided on the outlet side of the.

A rail 11 on the outer peripheral surface of the combustion drum A is engaged and mounted on a roller 10 installed on the pedestal 3, and the combustion drum A is rotatably fixed in position on the pedestal 3.
The gear 12 and the speed control motor 13 on the outer peripheral surface of the combustion drum A
The rotation driving mechanism B is constructed by rotating the gear 14 around the chain 15 to drive the combustion drum A for speed control and forward / reverse rotation.

As in the embodiment of FIG. 1, the net drum a
_When the hopper D of ₃ is provided on the side of the smoke exhausting means E on the outlet side of the combustion drum A, the feed plate 1 which establishes and fixes the inner surface of the mesh drum a _{3 at} an angle so as to form a substantially spiral shape. The flame retardant introduced from the hopper D is conveyed in the direction of the inlet of the combustion drum A with the angle of the above being reversed.

Further, as in the embodiment of FIG. 3, the mesh drum a
_When the hopper D of ₃ is provided in the hopper C on the inlet side of the combustion drum A, the angle of the feed plate 1 of the mesh drum a ₃ is the same as that of the other drums a ₁ and a ₂ , so that the hopper D The flame-retardant material introduced from the above is conveyed toward the exit of the combustion drum A.

[0013]

The combustion drive drum B (each of the drums a ₁ , a ₂ and a _{3 is} rotated in the same direction) is rotated slowly by the rotary drive mechanism B, and when the waste is put into the hopper C and ignited, the waste is burned. a sent rotation and mesh drum a ₂ inner surface of the burned while being stirred by a feed plate 1 slowly to乍Ra outlet direction, the mesh drum a ₂ through the ash mesh of a net drum a ₂ produced by during the combustion It is separated between the outer drums a _{1 and} is also sent in the direction of the outlet by the feed plate 1 and is discharged from the discharge port 7 of the discharge means F.
And the slag is discharged to the ash container 9.

When a flame-retardant material such as food waste is charged from the hopper D in parallel with the waste charging from the hopper C, the flame-retardant material is rotated by the combustion drum A and the feed plate 1 on the inner surface of the mesh drum a ₃ . While being agitated, it is dried by the heat of combustion of the waste material of the mesh drum a ₂ , and the dried material is burned and sent slowly toward the outlet,

[0015] For example apparatus of FIG. 1, to fall from the outlet to the network drum a _2, further combusted with the waste of the net-drum a _2,

In the case of the apparatus of the embodiment shown in FIG. 3, the outlet reaches the discharge port 7 of the discharge means F, and from there, the combustion slag and the ash container 9
Is discharged to.

The ash produced by the combustion in the network drum a ₃ falls to the network drum a ₂ through the eyes of the net-drum a _3, are processed together with the ashes of the net drum a _2.

In addition, the rotation speed of the combustion drum A is adjusted by the rotary drive mechanism B in accordance with the kind and amount of waste and flame retardant, the state of combustion, and the rotation of waste and flame retardant. Agitation speed, advancing speed from the inlet side to the outlet side (retention time in the combustion drum), etc. are freely adjusted by adjusting the rotation speed of the combustion drum A, the angle of the feed plate 1, the size, the number of installations, etc. .

Smoke and gas generated by the combustion in the combustion drum enter the smoke circulation chamber 4 of the smoke exhausting means E from the outlet side, circulate by the guide of the partition plate 5 and enter the chimney 6 to be discharged to the outside. Here, since the chimney 6 is located in the smoke circulation chamber 4, it is heated by the high-temperature smoke and gas circulating in the smoke circulation chamber 4, and
The smoke and gas are recombusted in the chimney 6 and then discharged to the outside.

[0020]

[Effect] The combustion drum is rotationally driven to stir and rotate the wastes and flame retardants in the net drums a ₂ and a ₃ so that a new combustion surface is always exposed and the wastes and flame retardants are also exposed. By supplying oxygen between them to promote combustion, and the ash generated by combustion is automatically separated through the mesh drum,
The mixture of the combustion product and the ash disappears, and the combustion efficiency can be significantly improved.

[0021] In particular, waste that is general waste and flame-retardant materials such as food waste that are hard to burn due to a large amount of water are classified into separate hoppers C and D from the net drum a ₂ (waste) and net drum a. ₃ so as to put the (flame combustibles), since the flame combustibles net drum a ₃ to be burned with dry combustion heat of mesh drum a _2, combustion than in case of combustion remains both mixed The efficiency can be remarkably improved.

Since a hopper for charging waste and flame-retardant material, and a discharge means for combustion slag and ash are provided separately on the inlet side and the outlet side of the combustion drum, the input of waste and the combustion slag and ash are performed. There is an advantage that it can be taken out at any time and at the same time, and therefore, there is a part that is always burning in the combustion drum, and high heat is retained, and the new waste is sequentially dried by the heat and continuously burned. Therefore, even a flame-retardant material such as a water-rich garbage can be completely burned.

The rotation speed of the combustion drum is adjusted by a rotary drive mechanism in accordance with the type and amount of waste and flame retardant, the state of combustion, the stirring speed of the waste, and the speed of progress from the inlet to the outlet. (That is, the retention time of waste and flame-retardant material in the combustion drum) can be adjusted to an optimal state for combustion.
The flame retardant can be completely burned.

Since the incinerator is configured in a chimney shape like a cylinder, including the combustion drum having a triple cylinder structure,
The air can be spread efficiently throughout and improve combustion efficiency. Further, in the smoke exhausting means E, the chimney 6 is connected to the smoke circulation chamber 4
Since it is inside, it is heated by the hot smoke and gas circulating in the smoke circulation chamber 4, so that the smoke and gas in the chimney 6 are recombusted, and as a result, further complete combustion is achieved. Hazardous smoke, gas, dust ash, etc. are rarely emitted to the outside, which can contribute to reduction of pollution.

Since the combustion drum can be rotated not only in the forward rotation but also in the reverse rotation by the rotation driving mechanism, there is an advantage that the inside can be easily cleaned.
