[0002]

2. Description of the Related Art Conventionally, as a processing machine for cooking garbage such as vegetable waste, seafood waste and skin, meat and the like, and garbage such as garbage, garbage is decomposed and reduced by the fermentation action of aerobic fermentative bacteria. It is known that the waste is composted or burnable (Japanese Unexamined Patent Publication No. 7-96269 and Japanese Unexamined Utility Model Publication No. 63-140037).

[0003] However, in such a garbage disposer, an intense odorous gas is generated during the decomposition treatment of the garbage, and it is extremely difficult to discharge these gases to the outside as they are for environmental hygiene reasons. It is not allowed.

[0004] Therefore, as a deodorizing device juxtaposed to such a garbage disposal machine, a deodorization box is provided at an exhaust air receiving port connected to an exhaust air outlet of the garbage disposal machine. Has proposed a deodorizing apparatus provided with a plurality of deodorizing layers through which an exhaust air flow flowing from the exhaust air receiving port toward an exhaust air outlet provided in the deodorizing box comes into contact (JP-A-10-290976).
No.).

[0005]

However, in this deodorizing apparatus, since the bad odor of the gas discharged from the exhaust outlet of the garbage disposer is too strong, it is not sufficient to simply pass through a plurality of deodorizing layers. There is a drawback that a deodorizing treatment cannot be performed.

In this deodorizing apparatus, the deodorizing layer is formed by filling wood powder (sawdust), hair wrapping palm trunks, plant fiber chips such as palm nuts, and deodorizing materials such as soft stones,
Since the exhaust gas from the garbage disposal machine is passed between the deodorizing materials to perform the deodorizing treatment, there is a disadvantage that the contact between the malodorous gas and the deodorizing material is not sufficiently performed.

[0007]

SUMMARY OF THE INVENTION In view of the above circumstances, the present invention sends oxygen from a blower fan into a closed garbage disposal tank in a garbage disposal machine to aerobically ferment the garbage and produce garbage. The offensive odor gas generated in the processing tank is forcibly discharged through an exhaust pipe by an exhaust blower, and is passed through one or more deodorizing water tanks to perform deodorizing treatment. The present invention proposes a deodorizing device in which exhaust gas from a water tank is returned to the garbage disposal tank through a gas-liquid separation device.

[0008]
