Abstract

PROBLEM TO BE SOLVED: To provide a garbage disposal device which can decompose even garbage containing waste wood at a comparatively low temperature.SOLUTION: A garbage disposal device is provided with an air diffusion plate 32 inside a side face of a mixture container 12, where this air diffusion plate 32 is bow-shaped similarly to a bottom side surface of the mixture container 12. A top edge of the air diffusion plate 32 is welded to a side wall inner surface of the mixture container 12, and a lower edge of the air diffusion plate 32 extends to a position slightly higher than the bottom of the mixture container 12 and is provided with a spacer 33 between the air diffusion plate 32 and the side wall inner surface of the mixture container 12 so that the gap between the air diffusion plate 32 and the side wall inner surface of the mixture container 12 becomes large at the lower edge. The length of the air diffusion plate 32 is almost equal to the length of the mixture container 12; and therefore, a slit opening 34 with a width of e.g. about 10 mm is formed over the full length of the mixture container 12 to get air containing active oxygens such as hydroxy radical (HO ) produced by an electronized device 30 fed into the mixture container 12 through this opening 34.

Description

本発明は、野菜屑や木屑などを汚泥とともに活性酸素を利用して発酵分解する装置に関する。   The present invention relates to an apparatus for fermenting and decomposing vegetable waste, wood waste and the like together with sludge using active oxygen.

生ゴミなどを好気性分解発酵菌を用いて分解し、コンポスト（堆肥）に変化させる装置として、特許文献１及び特許文献２に開示される装置が知られている。   Devices disclosed in Patent Literature 1 and Patent Literature 2 are known as devices for decomposing raw garbage and the like using aerobic decomposing fermenting bacteria and changing them into compost.

特許文献１に開示される装置は、箱型容器内に好気性分解発酵菌からなるバイオ菌床槽を設け、このバイオ菌床槽に上方から生ごみを投入するとともに、箱型容器内に配置した撹拌羽を回転させることで発酵を促進する構造になっている。   The apparatus disclosed in Patent Document 1 is provided with a bio-bacteria bed tank made of aerobically degrading fermentation bacteria in a box-type container, and the garbage is put into this bio-bacteria bed tank from above and disposed in the box-type container. It has a structure that promotes fermentation by rotating the stirring blades.

また特許文献２には傾斜したコンベアを備えた走行可能な切替し装置を用いた堆肥製造装置が開示されている。この堆肥製造装置は生ゴミなどの堆肥原料を前記切替し装置のコンベアによって少しづつ移動させながら撹拌することで発酵を完了するものである。   Further, Patent Document 2 discloses a compost manufacturing apparatus using a travelable switching device provided with an inclined conveyor. This compost production apparatus completes fermentation by stirring the compost raw materials such as raw garbage while switching them little by little by the conveyor of the apparatus.

上記の特許文献１または２の処理装置における処理対象が野菜屑などであれば、短時間で発酵分解を完了させることができるが、もみ殻や木屑などのセルロースの含有量が多いものは処理時間が長くかかる。   If the processing object in the processing apparatus of Patent Document 1 or 2 is vegetable waste or the like, fermentation decomposition can be completed in a short time, but those having a high cellulose content such as rice husk and wood waste are processing time. Takes a long time.

そこで、特許文献３には活性酸素を利用した有機物（野菜屑や木屑など）を低温（２０〜６０℃）で加水分解する装置が提案されている。
この装置は野菜屑や木屑などを投入するドラム状容器内に撹拌羽を設けるとともに、容器の底部に多孔管を配置し、容器外に設置した電子化装置によって発生した活性酸素を含む空気を前記多孔管から容器内に噴出させ、容器内の野菜屑や木屑などを加水分解する構造になっている。 Therefore, Patent Document 3 proposes an apparatus that hydrolyzes organic matter (vegetable waste, wood waste, etc.) using active oxygen at a low temperature (20 to 60 ° C.).
This device is provided with stirring blades in a drum-shaped container into which vegetable waste, wood waste, etc. is charged, and a porous tube is disposed at the bottom of the container, and air containing active oxygen generated by an electronic device installed outside the container is It has a structure in which it is ejected from the perforated tube into the container to hydrolyze vegetable waste, wood waste, etc. in the container.

上記の電子化装置の構造は特許文献４に開示されている。即ち、電子化装置は、高電圧を流した放電針から電子を発生させる放電管の先端に電磁コイルを巻き付け、その中心に空気を流し込むことで空気中の酸素分子を励起させ、一重項酸素などの活性酸素種を生成するものである。   The structure of the above electronic apparatus is disclosed in Patent Document 4. That is, the electronic device wraps an electromagnetic coil around the tip of a discharge tube that generates electrons from a discharge needle that has passed a high voltage, and excites oxygen molecules in the air by flowing air into the center of the discharge coil, such as singlet oxygen To generate the active oxygen species.

特開２００８−１５５０９０号公報JP 2008-155090 A 特開２００１−３０２３８０号公報JP 2001-302380 A 実用新案登録第３１５０６２８号公報Utility Model Registration No. 3150628 実用新案登録第３１３３３８８号公報Utility Model Registration No. 3133388

特許文献３及び４に開示されるように、酸素分子に磁力線を作用することで一重項酸素を生じさせ、この一重項酸素に遊離電子を加えることで二重項酸素即ちスーパーオキシド（・Ｏ２ −）を生成し、このスーパーオキシド（・Ｏ２ −）に水素を加えることで過酸化水素（Ｈ２Ｏ２）とし、この過酸化水素（Ｈ２Ｏ２）から酸化力が極めて強いヒドロキシラジカル（ＨＯ・）を生成し、このヒドロキシラジカル（ＨＯ・）によって有機物中の炭素原子と水素原子間の結合（Ｃ−Ｈ）を切断することで有機物を分解することで、今まで分解しにくかった木屑なども短時間のうちに分解することができる。 As disclosed in Patent Documents 3 and 4, singlet oxygen is generated by acting magnetic field lines on oxygen molecules, and free electrons are added to the singlet oxygen to thereby form doublet oxygen, that is, superoxide (.O 2 - ) To form hydrogen peroxide (H 2 O 2 ) by adding hydrogen to this superoxide (· O 2 − ), and this hydrogen radical (H 2 O 2 ) is a hydroxyl radical with extremely strong oxidizing power. (HO.) Is generated, and this hydroxyl radical (HO.) Breaks the organic substance by breaking the bond (C—H) between the carbon atom and the hydrogen atom in the organic substance. Wood chips can be decomposed in a short time.

しかしながら、特許文献３に開示される装置にあっては、ドラム状容器の底部に空気の電子化装置とつながる多孔管を配置し、しかも多孔管に形成される孔は上方に向かって開口している。このため、多孔管の孔が野菜屑や木屑で塞がり易く、メンテナンスが面倒となる。   However, in the device disclosed in Patent Document 3, a porous tube connected to an air electronic device is disposed at the bottom of the drum-like container, and the holes formed in the porous tube open upward. Yes. For this reason, the hole of a perforated tube is easy to block with vegetable waste and wood waste, and maintenance becomes troublesome.

上記課題を解決するため、本発明に係る廃棄物の発酵分解装置は、撹拌部材が回転自在に収納された混合容器と、活性酸素種を含む空気を生成する電子化装置とを備え、前記混合容器の側壁には前記電子化装置からの空気供給管が接続され、この空気供給管が接続された側壁の内側には分気板が設けられ、この分気板の上端部は混合容器の側壁に溶接され、また分気板は下方に向かって徐々に混合容器の側壁との間隔が大きくなり、混合容器の側壁との間隔が大きくなった下端部が混合容器内に活性酸素種を含む空気を送り込む開口部となった構造である。   In order to solve the above-mentioned problems, a waste fermentation decomposition apparatus according to the present invention includes a mixing container in which a stirring member is rotatably accommodated, and an electronic device that generates air containing active oxygen species, and the mixing An air supply pipe from the electronic device is connected to the side wall of the container, and a separation plate is provided inside the side wall to which the air supply pipe is connected. The upper end portion of the distribution plate is the side wall of the mixing container. In addition, the air gap between the separation plate and the side wall of the mixing vessel gradually increases downward, and the lower end of the separation plate with the side wall of the mixing vessel is increased. It is the structure which became the opening part which sends in.

前記分気板は混合容器の側壁の内側に配置されるため、攪拌部材と干渉しないようにすることが必要になる。このためには分気板の形状を円筒の一部をなす湾曲形状にするとともに、攪拌部材の回転方向を基準として上流側に前記分気板の上端部が溶接され、下流側に前記分気板の下端が位置するように分気板を取付けることが好ましい。 Since the separation plate is disposed inside the side wall of the mixing container, it is necessary to prevent interference with the stirring member. For this purpose, the shape of the separation plate is a curved shape forming a part of a cylinder, the upper end of the separation plate is welded upstream with respect to the rotation direction of the stirring member, and the separation plate is disposed downstream. It is preferable to attach the air distribution plate so that the lower end of the plate is located.

また、混合容器の側壁と分気板との溶接部はゴミが引っかからないように、なるべく段差が生じないように面一に接続することが好ましい。 In addition, it is preferable that the welded portion between the side wall of the mixing container and the air separation plate be connected flush with each other so as not to cause a step as much as possible so that dust is not caught.

また、混合容器の側壁内側面と分気板の外側面との間に形成される空気の供給路内にゴミが入って空気の供給路を塞ぐことがないようにするために、空気の供給路は攪拌部材の回転方向に沿って形成され、且つ下端の開口部は混合容器の底部よりも若干高い位置となるのが好ましい。   In addition, in order to prevent dust from entering the air supply path formed between the inner side surface of the side wall of the mixing container and the outer side surface of the separation plate, air supply is prevented. The path is preferably formed along the rotation direction of the stirring member, and the opening at the lower end is preferably slightly higher than the bottom of the mixing container.

本発明に係る廃棄物の発酵分解装置によれば、混合容器内に活性酸素種を含む空気を送り込む構造が、分気板を混合容器の側壁の内側に取り付け、この分気板と混合容器の側壁との間を活性酸素種を含む空気の供給路とし、分気板の下端と混合容器の側壁との間に形成されるスリット状の開口部から、活性酸素種を含む空気を混合容器内に噴出するようにしたので、特許文献３に開示された多孔パイプを用いる場合と比較して、均一且つ大量に活性酸素種を含む空気を混合容器内に送り込むことができる。したがって、反応処理時間を大幅に短縮することができる。   According to the fermentative decomposition apparatus for waste according to the present invention, the structure in which air containing active oxygen species is fed into the mixing container is attached to the inside of the side wall of the mixing container. An air supply path containing active oxygen species is provided between the side walls, and air containing active oxygen species is introduced into the mixing container from a slit-shaped opening formed between the lower end of the separation plate and the side wall of the mixing container. As compared with the case where the porous pipe disclosed in Patent Document 3 is used, air containing active oxygen species in a large amount can be fed into the mixing container. Therefore, the reaction processing time can be greatly shortened.

またプラスチックなどは発酵菌では分解できないため、分別して焼却処理によりガスする。この際、焼却温度が４００〜７００℃の場合はダイオキシンが発生するおそれがあるので、温度管理を行う。 Plastics cannot be decomposed by fermenting bacteria, so they are separated and gasified by incineration. At this time, when the incineration temperature is 400 to 700 ° C., dioxins may be generated, and therefore temperature management is performed.

また本発明に係る発酵分解装置は、異臭の発生が少なく、装置の管理・維持も簡単で、コスト的にも有利である。   In addition, the fermentation decomposition apparatus according to the present invention generates less off-flavors, is easy to manage and maintain, and is advantageous in terms of cost.

以下に本発明の実施例を添付図面に基づいて説明する。
廃棄物処理システムは図１の右端を原料の受入れ部１とし、この受入れ部１に隣接して発酵分解部２が設けられ、この発酵分解部２に隣接して発酵熟成ライン３が設けられ、この発酵熟成ライン３に隣接する左端を堆肥の取出し部４としている。 Embodiments of the present invention will be described below with reference to the accompanying drawings.
The waste treatment system has a raw material receiving unit 1 at the right end of FIG. 1, a fermentation decomposition unit 2 is provided adjacent to the reception unit 1, and a fermentation ripening line 3 is provided adjacent to the fermentation decomposition unit 2, The left end adjacent to the fermentation ripening line 3 is used as a compost take-out portion 4.

前記発酵分解部２には本発明に係る発酵分解装置１０を２基づつ２列に分けて配置している。   In the fermentation decomposition unit 2, two fermentation decomposition apparatuses 10 according to the present invention are arranged in two rows.

発酵分解装置１０は基台１１に混合容器１２が固定されている。この混合容器１２は底部を断面Ｕ字状とし、上面に生ゴミや汚泥などの原料投入口１３が形成され、この原料投入口１３を蓋１４で閉じている。   In the fermentation decomposition apparatus 10, a mixing container 12 is fixed to a base 11. The mixing vessel 12 has a U-shaped cross section at the bottom, and a raw material inlet 13 such as garbage or sludge is formed on the top surface. The raw material inlet 13 is closed by a lid 14.

また混合容器１２の中心には水平軸１５が挿通され、この水平軸１５の両端が基台１１に設けられた軸受１６，１６に回転自在に支持されている。また基台１１にはモータ１７が固設され、このモータ１７の駆動軸に取付けたギヤ１８と前記水平軸１５に取付けたギヤ１９間にチェーン２０を掛け渡すことで水平軸１５が回転せしめられる。   A horizontal shaft 15 is inserted through the center of the mixing container 12, and both ends of the horizontal shaft 15 are rotatably supported by bearings 16, 16 provided on the base 11. A motor 17 is fixed to the base 11, and the horizontal shaft 15 is rotated by passing a chain 20 between a gear 18 attached to the drive shaft of the motor 17 and a gear 19 attached to the horizontal shaft 15. .

前記水平軸１５には水平軸１５と一体的に回転する図６に示す形状の撹拌部材２１が取り付けられている。この撹拌部材２１は水平軸１５に一端が連結するアーム２２とこのアーム２２の外端部に固定されるブレード２３からなる。尚、撹拌部材２１の形状は図示したものに限定されない。   A stirring member 21 having the shape shown in FIG. 6 that rotates integrally with the horizontal shaft 15 is attached to the horizontal shaft 15. The stirring member 21 includes an arm 22 having one end connected to the horizontal shaft 15 and a blade 23 fixed to the outer end portion of the arm 22. In addition, the shape of the stirring member 21 is not limited to what was illustrated.

また、混合容器１２の底部には処理後の原料の取出し口２４が形成され、この取出し口２４を開閉する蓋２５を動作せしめるシリンダユニット２６が混合容器１２の側壁外側面に取付けられている。   Further, a raw material outlet 24 is formed at the bottom of the mixing container 12, and a cylinder unit 26 for operating a lid 25 for opening and closing the outlet 24 is attached to the outer side wall of the mixing container 12.

前記原料の取出し口２４の下方には発酵分解された原料を搬送するためのスクリューフィーダ２７が配置され、このスクリューフィーダ２７の端部には搬送されてきた原料を原料落下口２８まで搬送するコンベア装置２９が配置されている。   A screw feeder 27 for conveying the fermented and decomposed raw material is disposed below the raw material take-out port 24, and a conveyor that conveys the conveyed raw material to the raw material dropping port 28 at the end of the screw feeder 27. A device 29 is arranged.

一方、発酵分解装置１０の近傍には活性酸素種を含む空気を生成する電子化装置３０が配置され、混合容器１２の側面に電子化装置３０からの空気供給管が連結されるジョイント３１が取付けられている。   On the other hand, an electronic device 30 that generates air containing active oxygen species is disposed in the vicinity of the fermentation decomposition apparatus 10, and a joint 31 is attached to the side surface of the mixing container 12 to which an air supply pipe from the electronic device 30 is connected. It has been.

前記ジョイント３１が取付けられた混合容器１２の側面の内側には分気板３２が設けられている。この分気板３２の形状は混合容器１２の底部側面と同様の湾曲形状をしている。そして、分気板３２の上端は混合容器１２の側壁内側面に溶接され、分気板３２の下端部は混合容器１２の底部よりも若干高い位置まで伸び、且つ下端部において最も分気板３２と混合容器１２の側壁内側面との間隔が大きくなるように分気板３２と混合容器１２の側壁内側面との間にスペーサ３３を設けている。   A gas separation plate 32 is provided on the inner side of the side surface of the mixing container 12 to which the joint 31 is attached. The shape of the air distribution plate 32 has a curved shape similar to that of the bottom side surface of the mixing container 12. The upper end of the separation plate 32 is welded to the inner side surface of the side wall of the mixing container 12, the lower end portion of the separation plate 32 extends to a position slightly higher than the bottom portion of the mixing container 12, and the separation plate 32 is the most at the lower end portion. The spacer 33 is provided between the air separation plate 32 and the inner side surface of the side wall of the mixing container 12 so that the distance between the inner side surface and the inner side surface of the mixing container 12 is increased.

前記分気板３２の長さは混合容器１２の長さと略等しくされ、したがって、混合容器１２の全長に亘って幅が例えば１０ｍｍ程度のスリット状の開口部３４が形成され、この開口部３４から前記電子化装置３０で生成されたヒドロキシラジカル（ＨＯ・）などの活性酸素種を含む空気が混合容器１２内に送り込まれる。   The length of the air separation plate 32 is substantially equal to the length of the mixing container 12. Therefore, a slit-shaped opening 34 having a width of, for example, about 10 mm is formed over the entire length of the mixing container 12. Air containing active oxygen species such as hydroxy radicals (HO.) Generated by the electronic device 30 is sent into the mixing container 12.

ここで、混合容器１２内で撹拌されている原料が前記開口部３４に入らないようにするには、撹拌部材２１の回転方向を基準として、上流側に分気板３２の上端の溶接部が位置し、下流側に分気板３２の下端が位置する側に分気板３２を取付けるようにする。   Here, in order to prevent the raw material stirred in the mixing container 12 from entering the opening 34, the welded portion at the upper end of the air separation plate 32 is provided upstream with respect to the rotation direction of the stirring member 21. The separation plate 32 is attached to the side where the lower end of the separation plate 32 is located on the downstream side.

以上において、原料として例えば下水汚泥（消化汚泥及び生汚泥）と木材チップとを１００：４０の割合で混合したものを用意し、これを混合容器１２内に投入し、同時に電子化装置３０から活性酸素種を含んだ空気を約８ｍ３／分（混合容器の容量が２１ｍ３の場合）で供給する。 In the above, as a raw material, for example, a mixture of sewage sludge (digested sludge and raw sludge) and wood chips in a ratio of 100: 40 is prepared, and this is put into the mixing container 12 and simultaneously activated from the electronic device 30. Air containing oxygen species is supplied at about 8 m 3 / min (when the mixing vessel has a capacity of 21 m 3 ).

混合容器１２内では汚泥に含まれる好気性バクテリアによる分解の他に、供給された空気中に含まれるスーパーオキシド（・Ｏ２ −）、過酸化水素（Ｈ２Ｏ２）或いはヒドロキシラジカル（ＨＯ・）などの活性酸素種による有機物の分解が進行する。 In the mixing vessel 12, in addition to decomposition by aerobic bacteria contained in the sludge, superoxide (.O 2 − ), hydrogen peroxide (H 2 O 2 ) or hydroxy radical (HO.) Contained in the supplied air. Decomposition of organic substances by active oxygen species such as

上記の混合容器１２内での処理によりある程度原料の発酵分解が進行したならば、シリンダユニット２６の作動で蓋２５を移動し、混合容器１２の底部の原料の取出し口２４から原料をスクリューフィーダ２７内に移し、スクリューフィーダ２７により原料をコンベア装置２９まで送り出し、コンベア装置２９によって原料落下口２８から発酵分解が進んだ原料を落下せしめる。尚、スクリューフィーダ２７の代わりにベルトコンベアを用いてもよい。   If the fermentation decomposition of the raw material proceeds to some extent by the processing in the mixing container 12, the lid 25 is moved by the operation of the cylinder unit 26, and the raw material is supplied from the raw material take-out port 24 at the bottom of the mixing container 12 to the screw feeder 27. The raw material is fed to the conveyor device 29 by the screw feeder 27, and the raw material that has undergone fermentation decomposition is dropped from the raw material dropping port 28 by the conveyor device 29. A belt conveyor may be used instead of the screw feeder 27.

原料落下口２８にはトラクターが待ち受けており原料を受け取る。そして、受け取った原料を隣接する発酵熟成ライン３の床に積み上げる。発酵熟成ライン３の床に積み上げられた原料は移送装置４０によって所定量づつ下流側（図１において左側）へ送られる。   A tractor is waiting at the raw material outlet 28 and receives the raw material. And the received raw material is piled up on the floor of the adjacent fermentation ripening line 3. The raw material stacked on the floor of the fermentation and aging line 3 is sent to the downstream side (left side in FIG. 1) by a predetermined amount by the transfer device 40.

即ち、移送装置４０は斜めに傾斜したコンベア装置４１を備えると共に発酵熟成ライン３に沿って設けられたレール４２に走行可能に取り付けられている。
そして、発酵熟成ライン３の床に積み上げた原料はコンベア装置４１によって下流側に送られると共に上方から床面上に落下せしめられる。これにより原料は撹拌され、更に発酵と分解が進む。 That is, the transfer device 40 includes a conveyor device 41 that is inclined obliquely, and is attached to a rail 42 provided along the fermentation ripening line 3 so as to run.
And the raw material piled up on the floor of the fermentation ripening line 3 is sent to the downstream side by the conveyor apparatus 41, and is dropped on the floor surface from above. As a result, the raw material is stirred, and further fermentation and decomposition proceed.

発酵熟成ライン３に沿った原料の移動速度は３ｍ／日程度であり、２０日程度で熟成し堆肥となって取出し部４に到達する。堆肥の取出し部４では発酵分解が完了した原料を粒度選別機４３にかけ、堆肥として不都合な大きな粒子が混じっている場合には取り除く。   The moving speed of the raw material along the fermentation and ripening line 3 is about 3 m / day, matures in about 20 days and becomes compost and reaches the take-out part 4. The compost extraction unit 4 applies the raw material that has been fermented and decomposed to the particle size sorter 43, and removes large particles that are inconvenient as compost.

本発明に係る発酵分解装置は、野菜屑などの生ゴミに限らず、木屑やプラスチック片等が含まれる廃棄物も分解することができ、広い用途で適用可能である。   The fermentation decomposition apparatus according to the present invention is not limited to raw garbage such as vegetable waste, but can also decompose waste containing wood waste, plastic pieces, etc., and can be applied in a wide range of applications.

また特許文献２には傾斜したコンベアを備えた走行可能な切替し装置を用いた堆肥製造装置が開示されている。この堆肥製造装置は生ゴミなどの堆肥原料を前記切替し装置のコンベアによって少しづつ移動させながら撹拌することで発酵を完了するものである。   Further, Patent Document 2 discloses a compost manufacturing apparatus using a travelable switching device provided with an inclined conveyor. This compost production apparatus completes fermentation by stirring the compost raw materials such as raw garbage while switching them little by little by the conveyor of the apparatus.

上記の特許文献１または２の処理装置における処理対象が野菜屑などであれば、短時間で発酵分解を完了させることができるが、もみ殻や木屑などのセルロースの含有量が多いものは処理時間が長くかかる。   If the processing object in the processing apparatus of Patent Document 1 or 2 is vegetable waste or the like, fermentation decomposition can be completed in a short time, but those having a high cellulose content such as rice husk and wood waste are processing time. Takes a long time.

そこで、特許文献３には活性酸素を利用した有機物（野菜屑や木屑など）を低温（２０〜６０℃）で加水分解する装置が提案されている。
この装置は野菜屑や木屑などを投入するドラム状容器内に撹拌羽を設けるとともに、容器の底部に多孔管を配置し、容器外に設置した電子化装置によって発生した活性酸素を含む空気を前記多孔管から容器内に噴出させ、容器内の野菜屑や木屑などを加水分解する構造になっている。 Therefore, Patent Document 3 proposes an apparatus that hydrolyzes organic matter (vegetable waste, wood waste, etc.) using active oxygen at a low temperature (20 to 60 ° C.).
This device is provided with stirring blades in a drum-shaped container into which vegetable waste, wood waste, etc. is charged, and a porous tube is disposed at the bottom of the container, and air containing active oxygen generated by an electronic device installed outside the container is It has a structure in which it is ejected from the perforated tube into the container to hydrolyze vegetable waste, wood waste, etc. in the container.

上記の電子化装置の構造は特許文献４に開示されている。即ち、電子化装置は、高電圧を流した放電針から電子を発生させる放電管の先端に電磁コイルを巻き付け、その中心に空気を流し込むことで空気中の酸素分子を励起させ、一重項酸素などの活性酸素種を生成するものである。   The structure of the above electronic apparatus is disclosed in Patent Document 4. That is, the electronic device wraps an electromagnetic coil around the tip of a discharge tube that generates electrons from a discharge needle that has passed a high voltage, and excites oxygen molecules in the air by flowing air into the center of the discharge coil, such as singlet oxygen To generate the active oxygen species.

特許文献３及び４に開示されるように、酸素分子に磁力線を作用することで一重項酸素を生じさせ、この一重項酸素に遊離電子を加えることで二重項酸素即ちスーパーオキシド（・Ｏ２ −）を生成し、このスーパーオキシド（・Ｏ２ −）に水素を加えることで過酸化水素（Ｈ２Ｏ２）とし、この過酸化水素（Ｈ２Ｏ２）から酸化力が極めて強いヒドロキシラジカル（ＨＯ・）を生成し、このヒドロキシラジカル（ＨＯ・）によって有機物中の炭素原子と水素原子間の結合（Ｃ−Ｈ）を切断することで有機物を分解することで、今まで分解しにくかった木屑なども短時間のうちに分解することができる。 As disclosed in Patent Documents 3 and 4, singlet oxygen is generated by acting magnetic field lines on oxygen molecules, and free electrons are added to the singlet oxygen to thereby form doublet oxygen, that is, superoxide (.O 2 - ) To form hydrogen peroxide (H 2 O 2 ) by adding hydrogen to this superoxide (· O 2 − ), and this hydrogen radical (H 2 O 2 ) is a hydroxyl radical with extremely strong oxidizing power. (HO.) Is generated, and this hydroxyl radical (HO.) Breaks the organic substance by breaking the bond (C—H) between the carbon atom and the hydrogen atom in the organic substance. Wood chips can be decomposed in a short time.

しかしながら、特許文献３に開示される装置にあっては、ドラム状容器の底部に空気の電子化装置とつながる多孔管を配置し、しかも多孔管に形成される孔は上方に向かって開口している。このため、多孔管の孔が野菜屑や木屑で塞がり易く、メンテナンスが面倒となる。   However, in the device disclosed in Patent Document 3, a porous tube connected to an air electronic device is disposed at the bottom of the drum-like container, and the holes formed in the porous tube open upward. Yes. For this reason, the hole of a perforated tube is easy to block with vegetable waste and wood waste, and maintenance becomes troublesome.

上記課題を解決するため、本発明に係る廃棄物の発酵分解装置は、撹拌部材が回転自在に収納された混合容器と、活性酸素種を含む空気を生成する電子化装置とを備え、前記混合容器の側壁には前記電子化装置からの空気供給管が接続され、この空気供給管が接続された側壁の内側には分気板が設けられ、この分気板の上端部は混合容器の側壁に溶接され、また分気板は下方に向かって徐々に混合容器の側壁との間隔が大きくなり、混合容器の側壁との間隔が大きくなった下端部が混合容器内に活性酸素種を含む空気を送り込む開口部となった構造である。   In order to solve the above-mentioned problems, a waste fermentation decomposition apparatus according to the present invention includes a mixing container in which a stirring member is rotatably accommodated, and an electronic device that generates air containing active oxygen species, and the mixing An air supply pipe from the electronic device is connected to the side wall of the container, and a separation plate is provided inside the side wall to which the air supply pipe is connected. The upper end portion of the distribution plate is the side wall of the mixing container. In addition, the air gap between the separation plate and the side wall of the mixing vessel gradually increases downward, and the lower end of the separation plate with the side wall of the mixing vessel is increased. It is the structure which became the opening part which sends in.

前記分気板は混合容器の側壁の内側に配置されるため、攪拌部材と干渉しないようにすることが必要になる。このためには分気板の形状を円筒の一部をなす湾曲形状にするとともに、攪拌部材の回転方向を基準として上流側に前記分気板の上端部が溶接され、下流側に前記分気板の下端が位置するように分気板を取付けることが好ましい。 Since the separation plate is disposed inside the side wall of the mixing container, it is necessary to prevent interference with the stirring member. For this purpose, the shape of the separation plate is a curved shape forming a part of a cylinder, the upper end of the separation plate is welded upstream with respect to the rotation direction of the stirring member, and the separation plate is disposed downstream. It is preferable to attach the air distribution plate so that the lower end of the plate is located.

また、混合容器の側壁と分気板との溶接部はゴミが引っかからないように、なるべく段差が生じないように面一に接続することが好ましい。 In addition, it is preferable that the welded portion between the side wall of the mixing container and the air separation plate be connected flush with each other so as not to cause a step as much as possible so that dust is not caught.

また、混合容器の側壁内側面と分気板の外側面との間に形成される空気の供給路内にゴミが入って空気の供給路を塞ぐことがないようにするために、空気の供給路は攪拌部材の回転方向に沿って形成され、且つ下端の開口部は混合容器の底部よりも若干高い位置となるのが好ましい。   In addition, in order to prevent dust from entering the air supply path formed between the inner side surface of the side wall of the mixing container and the outer side surface of the separation plate, air supply is prevented. The path is preferably formed along the rotation direction of the stirring member, and the opening at the lower end is preferably slightly higher than the bottom of the mixing container.

本発明に係る廃棄物の発酵分解装置によれば、混合容器内に活性酸素種を含む空気を送り込む構造が、分気板を混合容器の側壁の内側に取り付け、この分気板と混合容器の側壁との間を活性酸素種を含む空気の供給路とし、分気板の下端と混合容器の側壁との間に形成されるスリット状の開口部から、活性酸素種を含む空気を混合容器内に噴出するようにしたので、特許文献３に開示された多孔パイプを用いる場合と比較して、均一且つ大量に活性酸素種を含む空気を混合容器内に送り込むことができる。したがって、反応処理時間を大幅に短縮することができる。   According to the fermentative decomposition apparatus for waste according to the present invention, the structure in which air containing active oxygen species is fed into the mixing container is attached to the inside of the side wall of the mixing container. An air supply path containing active oxygen species is provided between the side walls, and air containing active oxygen species is introduced into the mixing container from a slit-shaped opening formed between the lower end of the separation plate and the side wall of the mixing container. As compared with the case where the porous pipe disclosed in Patent Document 3 is used, air containing active oxygen species in a large amount can be fed into the mixing container. Therefore, the reaction processing time can be greatly shortened.

前記発酵分解部２には本発明に係る発酵分解装置１０を２基づつ２列に分けて配置している。   In the fermentation decomposition unit 2, two fermentation decomposition apparatuses 10 according to the present invention are arranged in two rows.

発酵分解装置１０は基台１１に混合容器１２が固定されている。この混合容器１２は底部を断面Ｕ字状とし、上面に生ゴミや汚泥などの原料投入口１３が形成され、この原料投入口１３を蓋１４で閉じている。   In the fermentation decomposition apparatus 10, a mixing container 12 is fixed to a base 11. The mixing vessel 12 has a U-shaped cross section at the bottom, and a raw material inlet 13 such as garbage or sludge is formed on the top surface. The raw material inlet 13 is closed by a lid 14.

A motor 17 is fixed to the base 11, and the horizontal shaft 15 is rotated by passing a chain 20 between a gear 18 attached to the drive shaft of the motor 17 and a gear 19 attached to the horizontal shaft 15. .

前記水平軸１５には水平軸１５と一体的に回転する図６に示す形状の撹拌部材２１が取り付けられている。この撹拌部材２１は水平軸１５に一端が連結するアーム２２とこのアーム２２の外端部に固定されるブレード２３からなる。尚、撹拌部材２１の形状は図示したものに限定されない。   A stirring member 21 having the shape shown in FIG. 6 that rotates integrally with the horizontal shaft 15 is attached to the horizontal shaft 15. The stirring member 21 includes an arm 22 having one end connected to the horizontal shaft 15 and a blade 23 fixed to the outer end portion of the arm 22. In addition, the shape of the stirring member 21 is not limited to what was illustrated.

また、混合容器１２の底部には処理後の原料の取出し口２４が形成され、この取出し口２４を開閉する蓋２５を動作せしめるシリンダユニット２６が混合容器１２の側壁外側面に取付けられている。   Further, a raw material outlet 24 is formed at the bottom of the mixing container 12, and a cylinder unit 26 for operating a lid 25 for opening and closing the outlet 24 is attached to the outer side wall of the mixing container 12.

前記原料の取出し口２４の下方には発酵分解された原料を搬送するためのスクリューフィーダ２７が配置され、このスクリューフィーダ２７の端部には搬送されてきた原料を原料落下口２８まで搬送するコンベア装置２９が配置されている。   A screw feeder 27 for conveying the fermented and decomposed raw material is disposed below the raw material take-out port 24, and a conveyor for conveying the conveyed raw material to the raw material dropping port 28 at the end of the screw feeder 27. A device 29 is arranged.

一方、発酵分解装置１０の近傍には活性酸素種を含む空気を生成する電子化装置３０が配置され、混合容器１２の側面に電子化装置３０からの空気供給管が連結されるジョイント３１が取付けられている。   On the other hand, an electronic device 30 that generates air containing active oxygen species is disposed in the vicinity of the fermentation decomposition apparatus 10, and a joint 31 is attached to the side surface of the mixing container 12 to which an air supply pipe from the electronic device 30 is connected. It has been.

前記ジョイント３１が取付けられた混合容器１２の側面の内側には分気板３２が設けられている。この分気板３２の形状は混合容器１２の底部側面と同様の湾曲形状をしている。そして、分気板３２の上端は混合容器１２の側壁内側面に溶接され、分気板３２の下端部は混合容器１２の底部よりも若干高い位置まで伸び、且つ下端部において最も分気板３２と混合容器１２の側壁内側面との間隔が大きくなるように分気板３２と混合容器１２の側壁内側面との間にスペーサ３３を設けている。   A gas separation plate 32 is provided on the inner side of the side surface of the mixing container 12 to which the joint 31 is attached. The shape of the air distribution plate 32 has a curved shape similar to that of the bottom side surface of the mixing container 12. The upper end of the separation plate 32 is welded to the inner side surface of the side wall of the mixing container 12, the lower end portion of the separation plate 32 extends to a position slightly higher than the bottom portion of the mixing container 12, and the separation plate 32 is the most at the lower end portion. The spacer 33 is provided between the air separation plate 32 and the inner side surface of the side wall of the mixing container 12 so that the distance between the inner side surface and the inner side surface of the mixing container 12 is increased.

前記分気板３２の長さは混合容器１２の長さと略等しくされ、したがって、混合容器１２の全長に亘って幅が例えば１０ｍｍ程度のスリット状の開口部３４が形成され、この開口部３４から前記電子化装置３０で生成されたヒドロキシラジカル（ＨＯ・）などの活性酸素種を含む空気が混合容器１２内に送り込まれる。   The length of the air separation plate 32 is substantially equal to the length of the mixing container 12. Therefore, a slit-shaped opening 34 having a width of, for example, about 10 mm is formed over the entire length of the mixing container 12. Air containing active oxygen species such as hydroxy radicals (HO.) Generated by the electronic device 30 is sent into the mixing container 12.

The separation plate 32 is attached to the side where the lower end of the separation plate 32 is located on the downstream side.

以上において、原料として例えば下水汚泥（消化汚泥及び生汚泥）と木材チップとを１００：４０の割合で混合したものを用意し、これを混合容器１２内に投入し、同時に電子化装置３０から活性酸素種を含んだ空気を約８ｍ３／分（混合容器の容量が２１ｍ３の場合）で供給する。 In the above, as a raw material, for example, a mixture of sewage sludge (digested sludge and raw sludge) and wood chips in a ratio of 100: 40 is prepared, and this is put into the mixing container 12 and simultaneously activated from the electronic device 30. Air containing oxygen species is supplied at about 8 m 3 / min (when the mixing vessel has a capacity of 21 m 3 ).

混合容器１２内では汚泥に含まれる好気性バクテリアによる分解の他に、供給された空気中に含まれるスーパーオキシド（・Ｏ２ −）、過酸化水素（Ｈ２Ｏ２）或いはヒドロキシラジカル（ＨＯ・）などの活性酸素種による有機物の分解が進行する。 In the mixing vessel 12, in addition to decomposition by aerobic bacteria contained in the sludge, superoxide (.O 2 − ), hydrogen peroxide (H 2 O 2 ) or hydroxy radical (HO.) Contained in the supplied air. Decomposition of organic substances by active oxygen species such as

上記の混合容器１２内での処理によりある程度原料の発酵分解が進行したならば、シリンダユニット２６の作動で蓋２５を移動し、混合容器１２の底部の原料の取出し口２４から原料をスクリューフィーダ２７内に移し、スクリューフィーダ２７またはベルトコンベアにより原料をコンベア装置２９まで送り出し、コンベア装置２９によって原料落下口２８から発酵分解が進んだ原料を落下せしめる。   If the fermentation decomposition of the raw material proceeds to some extent by the processing in the mixing container 12, the lid 25 is moved by the operation of the cylinder unit 26, and the raw material is supplied from the raw material take-out port 24 at the bottom of the mixing container 12 to the screw feeder 27. The raw material is fed to the conveyor device 29 by the screw feeder 27 or the belt conveyor, and the raw material that has undergone fermentation decomposition is dropped from the raw material dropping port 28 by the conveyor device 29.

原料落下口２８にはトラクターが待ち受けており原料を受け取る。そして、受け取った原料を隣接する発酵熟成ライン３の床に積み上げる。発酵熟成ライン３の床に積み上げられた原料は移送装置４０によって所定量づつ下流側（図１において左側）へ送られる。   A tractor is waiting at the raw material outlet 28 and receives the raw material. And the received raw material is piled up on the floor of the adjacent fermentation ripening line 3. The raw material stacked on the floor of the fermentation and aging line 3 is sent to the downstream side (left side in FIG. 1) by a predetermined amount by the transfer device 40.

即ち、移送装置４０は斜めに傾斜したコンベア装置４１を備えると共に発酵熟成ライン３に沿って設けられたレール４２に走行可能に取り付けられている。
そして、発酵熟成ライン３の床に積み上げた原料はコンベア装置４１によって下流側に送られると共に上方から床面上に落下せしめられる。これにより原料は撹拌され、更に発酵と分解が進む。 That is, the transfer device 40 includes a conveyor device 41 that is inclined obliquely, and is attached to a rail 42 provided along the fermentation ripening line 3 so as to run.
And the raw material piled up on the floor of the fermentation ripening line 3 is sent to the downstream side by the conveyor apparatus 41, and is dropped on the floor surface from above. As a result, the raw material is stirred, and further fermentation and decomposition proceed.

発酵熟成ライン３に沿った原料の移動速度は３ｍ／日程度であり、２０日程度で熟成し堆肥となって取出し部４に到達する。堆肥の取出し部４では発酵分解が完了した原料を粒度選別機４３にかけ、堆肥として不都合な大きな粒子が混じっている場合には取り除く。   The moving speed of the raw material along the fermentation and ripening line 3 is about 3 m / day, matures in about 20 days and becomes compost and reaches the take-out part 4. The compost extraction unit 4 applies the raw material that has been fermented and decomposed to the particle size sorter 43, and removes large particles that are inconvenient as compost.
