DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for burning feces and the like. More specifically, the present invention relates to a combustion apparatus capable of efficiently incinerating animal waste such as chicken dung, waste such as cake obtained by dehydrating activated sludge, laying material such as a barn or garbage without generating a bad odor. .

[0002]

2. Description of the Related Art For example, in recent years, the breeding of broilers, which is a source of chicken meat, has been gradually increasing in scale, but with this, treatment of chicken manure has become a major problem. Methods of treating chicken dung include composting and incineration. Composting is most desirable in terms of effective utilization of chicken dung,
As a practical matter, the demand is small and it cannot be sold, so the amount that can be processed is limited. Therefore, in recent years, incineration of cattle and pig manure as well as poultry manure has become commonplace, but it has become a social problem due to the generation of offensive odors. A deodorant combustion device has been proposed.

[0003]

However, the above-mentioned conventional combustion apparatus has the following problems. That is,
In the case of the reburning type combustion device, extra fuel for reburning is required, and the processing cost increases. In addition, even in a system in which a chemical reaction is caused by a chemical to deodorize, the processing cost is still increased due to the use of the chemical. In addition, there is a problem that the processing speed is slow in any of the above cases, and it is not functionally sufficient to process a large amount of chicken dung.

The present invention solves the above-mentioned problems. For example, it is possible to generate odors from livestock dung such as chicken dung, waste such as cakes obtained by dehydrating activated sludge, laid objects such as livestock barns, and garbage. It is an object of the present invention to provide a combustion device which can be incinerated efficiently without any problem.

Thereafter, the high-temperature gas is discharged from the ventilation holes 21 to the outside through the exhaust duct 3. If the odor still leaks outside the device, the auxiliary burner device 26
Can be operated to burn odor components in the high-temperature gas.

The odor gas generated from the feces storage 9 stored in the storage unit 1 is directly supplied to the combustion unit 4 by the gas supply device 8 and can be burned. Since the gas pressure in the storage unit 1 is reduced by drawing the gas with the fan device 81, the odor gas can be prevented from leaking to the outside. The ash after the feces storage 9 has been burned is discharged to the outside by the ash discharging device 7.

As described above, since the feces storage 9 is preheated in advance by the heating and transporting cylinder 20 which is heated by using the high-temperature gas generated in the combustion section 4 to burn off moisture before burning. The combustion in the combustion section 4 can be performed efficiently without requiring auxiliary fuel or the like.
