Description

本発明は、食品廃棄物などの処理装置であって、とくに好気性発酵菌を利用する有機性廃棄物処理装置に関するものである。   The present invention relates to a processing apparatus for food waste and the like, and more particularly to an organic waste processing apparatus that uses aerobic fermentative bacteria.

従来の有機性廃棄物処理装置は、処理槽に生ゴミ等の有機性廃棄物を投入し、撹拌羽根を回転させることにより処理槽内の有機性廃棄物と発酵菌とを混ぜ合わせるとともに、撹拌羽根から処理槽内に温風を吹き出すことによって有機性廃棄物から水分を蒸発させ、有機性廃棄物に適度な温度と湿度を与えることにより、効果的な発酵を確保して有機性廃棄物の発酵分解を促進させるように構成されている。   Conventional organic waste treatment equipment mixes organic waste and fermenting bacteria in the treatment tank by putting organic waste such as garbage into the treatment tank and rotating the stirring blades, and stirring. By blowing warm air from the blades into the treatment tank, the water is evaporated from the organic waste, and by giving the organic waste an appropriate temperature and humidity, effective fermentation is ensured. It is configured to promote fermentation decomposition.

しかしながら、上記の有機性廃棄物処理装置では、処理機から送出される排気がそのまま外部に放出される構造となっており、排気の悪臭が外部にまき散らされるという問題があり、処理装置に付随して脱臭装置を設置する必要があった。   However, the above-mentioned organic waste treatment apparatus has a structure in which the exhaust gas sent from the treatment machine is discharged to the outside as it is, and there is a problem that the bad smell of the exhaust gas is scattered outside. It was necessary to install a deodorizing device.

そこで、処理槽に投入された被処理物に向けて温風を送出する温風発生器と、処理槽内の湿潤した温風を除湿するとともに、除湿された空気を筐体の外部に排出することなく、前記温風発生器に環流して温風発生器から再度処理槽に送出させる温風の循環送風手段とを設けた有機性廃棄物処理装置が提案されている（特許文献１参照。）。   Therefore, a hot air generator that sends out hot air toward the object to be processed put into the processing tank, and dehumidified hot air in the processing tank are dehumidified, and the dehumidified air is discharged to the outside of the housing. There has been proposed an organic waste treatment apparatus provided with a circulating air blowing means for circulating warm air to the hot air generator and sending it from the hot air generator to the treatment tank again (see Patent Document 1). ).

しかしながら、上記特許文献１に提案されている有機性廃棄物処理装置は、処理槽と、温風発生器と、温風の循環送風手段とを密閉可能な筐体内に収容し、処理槽内で発生する臭気が外部に放出させない構造とするものであるが、外気と完全に遮断した状態で温風を循環させることは極めて困難なものであり、必然的に臭気が外部に漏れるものであり、脱臭のための脱臭装置が必要となるものであった。   However, the organic waste treatment apparatus proposed in Patent Document 1 contains a treatment tank, a warm air generator, and a circulating means for circulating hot air in a sealable casing, Although the structure is designed to prevent the generated odor from being released to the outside, it is extremely difficult to circulate hot air in a state of being completely cut off from the outside air, and odor inevitably leaks to the outside. A deodorizing device for deodorization is required.

上記の問題点に鑑み本発明者は、有機性廃棄物を好気性発酵菌によって発酵分解処理する際に発生するガスを再利用すると共に、バーナーの燃焼によって脱臭を行なうことができる有機性廃棄物処理装置を提供するに至った。   In view of the above problems, the present inventor recycles the gas generated when the organic waste is fermented and decomposed by aerobic fermentation bacteria, and the organic waste can be deodorized by burning the burner.

この構成において、主バーナーの燃料は通常の灯油、重油だけでなく天ぷら油、廃油などの代替燃料が使用され、また燃焼用空気として処理槽内で発生する臭気を含んだガスが使用され、種火バーナーによって着火される。   In this configuration, the fuel for the main burner is not only ordinary kerosene and heavy oil, but also alternative fuels such as tempura oil and waste oil, and gas containing odors generated in the treatment tank is used as combustion air. Ignited by a fire burner.

The gas containing odor generated from the organic waste that is used in the fermentation treatment of organic waste and fermented in the treatment tank is again reused together with the heated outside air circulating in the treatment tank. It is used as combustion air for the burner and has the effect that it can be deodorized when the main burner is burned.

尚、主バーナーの燃料には灯油、重油だけでなく、天ぷら油、廃油などの代替燃料が使用できる。   As the fuel for the main burner, not only kerosene and heavy oil but also alternative fuels such as tempura oil and waste oil can be used.

さらに、燃焼用空気の送気経路を三方弁によって変更することが可能であり、主バーナーの消火後であっても、燃焼用空気に含まれる臭気を含んだガスをスクラバーによって脱臭できるという効果を有する。   Furthermore, it is possible to change the air supply path of the combustion air with a three-way valve, and even after the main burner is extinguished, the gas containing the odor contained in the combustion air can be deodorized by the scrubber.

Moreover, the spray apparatus is installed in the main body upper part, and sprinkles water in the cylindrical body 20 direction.

筒状体２０は、その内部に木炭２１が複数充填されており、表面にメッシュ状の開口部を有し上記したガスの通過やスプレー装置による散水の通過を自在とする。そして側面一端側には上記駆動装置と連結する連結管２２が設けられており、駆動装置の回動伝達軸２３と連結して周方向に回動可能とされている。筒状体の材質としては、防錆性のステンレスが望ましいが、ＦＲＰなどの強化プラスチックであっても構わない。   The cylindrical body 20 is filled with a plurality of charcoal 21 inside, and has a mesh-like opening on the surface, allowing the gas to pass and the spraying device to pass through. A connecting tube 22 connected to the driving device is provided at one end of the side surface, and is connected to the rotation transmission shaft 23 of the driving device so as to be rotatable in the circumferential direction. The material of the cylindrical body is preferably rust-proof stainless steel, but may be reinforced plastic such as FRP.

排気ファン１５によって吸引される有機性廃棄物の発酵時に発生する臭気を含んだガスは、三方弁１６を介してスクラバー装置１７のガス流入口から本体１９内に送気され、複数の筒状体２０を通過しながらガス排出口から大気へ放出される。この際、複数の筒状体２０は常に連動して周方向に回動しており、筒状体２０内の木炭２１とガスとの接触面積を変化させると共に、上部に設けられたスプレー装置からの散水によってガスに含まれる粉塵と臭気成分が取り除かれる。尚、落下した水は、一端受けタンクに溜められた後、再度ポンプによって散水装置へ送られて利用される。また、本実施例においては水を使用する例で説明したが、次亜塩素酸ソーダ溶液なども使用できる。 Gas containing odor generated during the fermentation of organic waste which is sucked by the exhaust fan 1 5 is air through the three-way valve 16 from the gas inlet of the scrubber unit 17 in the main body 19, a plurality of cylindrical While passing through the body 20, it is released from the gas outlet to the atmosphere. At this time, the plurality of cylindrical bodies 20 always rotate in the circumferential direction in conjunction with each other, change the contact area between the charcoal 21 and the gas in the cylindrical body 20, and from the spray device provided in the upper part. Dust and odor components contained in the gas are removed by water spraying. The dropped water is once stored in the receiving tank and then sent again to the watering device by the pump for use. Moreover, although the example which uses water demonstrated in the present Example, the sodium hypochlorite solution etc. can also be used.
