Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rollover type incinerator capable of efficiently incinerating highly water-containing wastes containing plenty of water such as fruit juice, sludge, waste liquid, and garbage. is there.

[0002]

BACKGROUND ART Incineration is a phenomenon in which organic matter in waste reacts with oxygen in the air (oxidation reaction) and burns with heat and light. Usually, in a so-called vertical type carbonization furnace, control air is introduced from the bottom, partial combustion is generated at the bottom, the adjacent part is heated by the heat, decomposition vaporization of organic matter begins, and the entire bottom becomes a fire bed. Following the (red heat layer), the upper part is decomposed and vaporized (fluidized layer), and the upper part is absorbed (heat transfer layer), and the uppermost part becomes decomposed gas (gas layer). Burn slowly to.

[0003] When the pyrolysis of the organic matter is completed, the carbonization ends and the carbonization reaction starts, and the decomposition gas attracted from the carbonization furnace is heated by the auxiliary combustion in the gas combustion furnace to supply the necessary air. Completely burned. However, as described above, the combustion of the organic substances mixed in the high water content waste by the conventional carbonization furnace is gradually burned from the lower part to the upper part as described above, and therefore, for example, fruit juice, sludge, waste liquid, or garbage. The burning efficiency of organic matter that is hard to incinerate with abundant moisture was very poor, and it was not suitable for incinerating such high water content waste.

[0004]

Therefore, in the conventional incineration treatment of high-water-content waste, it is necessary to introduce a dehydration treatment device into the waste, for example, by introducing a dehydration treatment apparatus into the waste. The amount of water contained is reduced as much as possible to carry out combustion treatment, or to mix combustion promoting materials etc. in the waste to improve combustion efficiency, or to set the gas burner temperature to an abnormally high temperature. At present, various methods are adopted.

Therefore, conventionally, in addition to an incinerator, a dehydration treatment device must be installed, a combustion promoting material needs to be specially purchased, and the temperature inside the furnace body is raised to an unnecessarily high temperature. Since it has to be set, there is a problem that fuel consumption becomes very expensive. In the case of the conventional vertical incinerator, waste such as high water content waste is supplied from the upper part of the incinerator and dropped while it is burned by the gas burner arranged below, so the amount of waste supplied is It is very difficult to control the burning rate, so it is very difficult to aim for complete incineration, and there are various residues such as a large amount of residue and therefore post-treatment is extremely complicated. Was there.

Therefore, in consideration of the above-mentioned problems, the lateral inversion incinerator 20 disclosed in FIG. 2 has been developed in the past. The overturning incinerator 20 is configured such that a overturning drive means 22 is provided above a main body base 21 and a furnace main body 23 is rotatably mounted above this. The overturning driving means 22 includes an electric motor 22a and a body gear 2 provided on an outer wall of the furnace body 23 at an output gear 22b of the electric motor 22a.
3a is engaged to laterally roll the furnace body 23, and the rolling furnace body 23 is a free rotating roller 22c, 22c provided on the left and right of the body base 21, and the left and right flanges 23b provided on the outer wall of the furnace body 23. , 23b, so that the furnace body 23 can smoothly roll over.

The overall shape of the furnace main body 23 has an opening 23d at the bottom 23c (located on the rear side), a small diameter on the bottom 23c side, and a large opening 23e (located on the front side). It has a large-diameter taper-like substantially bottomed cylinder shape. On the side of the large opening 23e, a gas burner 24 having a flame port facing the inside of the furnace body 23, a smoke exhausting means (including a dust collecting device) 25, and a residue discharge port 26 which can be opened and closed downwards.
And a closing body 28 having a blowing means 27. Further, the opening 23 is provided on the side of the bottom portion 23c.
Screw 2 with the supply port facing the inside of the furnace body 23 from d
A waste supply means 29 with a built-in 9a is provided, and the waste supply means 29 supplies a predetermined amount of waste in the hopper 30 into the furnace main body 23 for incineration.

However, the overturning incinerator 2 having the above structure
Furnace main body 23 facing the waste supply means 29 in No. 0
As shown in the same figure, the inside is constructed in a substantially hermetically sealed state, so that the furnace main body 2 is continuously screwed with the screw 29a.
Part of the water contained in the high water content waste supplied to the inside of the furnace 3 is immediately changed to steam when supplied to the inside of the furnace body 2
3 rises above the inner wall and lowers the temperature around the waste supply means 29, or adheres to the inner wall to significantly reduce combustion efficiency. Therefore, incomplete combustion is observed inside the furnace main body 23, secondary combustion is not easy, and the combustion temperature must be maintained in anticipation of such temperature decrease, resulting in increased fuel consumption. In addition, since adhesion of water vapor to the inner wall and repeated rapid heating and the like are repeated without interruption, durability of the inner wall of the furnace body 23 is significantly impaired, resulting in high frequency of separation of the inner wall surface of the furnace body 23 and maintenance cost. There was a problem that it became expensive.
