Description

Deodorizer {DEODORIZATION APPARATUS}

The present invention relates to a deodorizer installed in the kitchen waste processor.

Conventionally, as a processing device for kitchen waste such as vegetable waste, fish waste, shells, meat, etc., kitchen waste such as residues, it is known to decompose and reduce compost waste or combustible waste by fermentation of aerobic fermentation bacteria ( Japanese Patent Laid-Open Publication No. 95-96269 and Japanese Utility Model Publication No. 88-140037).

However, in such a kitchen waste processor, intense odor gas is generated during the decomposition treatment of the kitchen waste, and it is hardly allowed to discharge these gases to the outside for reasons such as nearby environmental hygiene.

Therefore, as a deodorizer installed in such a kitchen waste processor, a deodorization box is provided at a gas exhaust inlet connected to the gas exhaust outlet of the kitchen waste processor, and the deodorization box is provided from the gas exhaust inlet. There is proposed a deodorizer having a plurality of deodorization layers through which the gas exhaust flows toward the gas exhaust outlet provided in the deodorization box and passes therethrough (Japanese Patent Laid-Open No. 10-290976).

However, this deodorizing device has a drawback in that the odor of the gas discharged from the gas exhaust outlet of the kitchen waste processor is so intense that simply passing through a plurality of deodorizing layers does not allow sufficient deodorizing treatment.

In this deodorizing device, the deodorizing layer is formed by filling deodorant materials such as chips, curb, etc. of plant fiber such as wood powder (sawdust), hairs surrounding palm tree trunks, and coconut, and the exhaust gas from the kitchen waste treatment machine Since the deodorizing treatment is carried out by passing through the deodorizing material, there is a drawback that the odor gas is not sufficiently contacted with the deodorizing material.

SUMMARY OF THE INVENTION In view of the above circumstances, the present invention supplies oxygen from a blower fan to an airtight kitchen waste treatment tank in a kitchen waste treatment unit to exhalate the kitchen waste and exhausts the odor gas generated in the kitchen waste treatment tank by an exhaust blower. Deodorizing apparatus forcibly discharging through the deodorizing liquid contained in one or two deodorizing tanks and deodorizing and returning the exhaust gas from the deodorizing tank to the kitchen waste treatment tank through a gas-liquid separator. To propose.
