Description

本発明は、生ごみ、食品端材等の食品廃棄物を炭化処理するのに好適に用いられる有機物の炭化処理装置及び炭化処理方法に関するものである。 The present invention relates to an organic matter carbonization treatment apparatus and a carbonization treatment method preferably used for carbonizing food waste such as kitchen waste and food scraps.

従来の有機物の炭化処理技術において、本件発明者による食品廃棄物等の有機物の炭化処理を連続して行う炭化処理技術が知られている（特許文献１）。 In the conventional carbonization treatment technology for organic substances, there is known a carbonization treatment technology for continuously carbonizing organic substances such as food waste by the present inventor (Patent Document 1).

ＷＯ２０１３／０１１５５５Ａ１WO2013 / 011555A1

特許文献１に記載の技術は、有機物を収容するための収容容器と、該収容容器を移送する移送コンベアと、長さ方向の両端に開口部を有する管状体からなる炭化処理炉と、過熱水蒸気発生装置と、該過熱水蒸気発生装置で発生する過熱水蒸気を前記炭化処理炉の内部に供給する供給管部とを備え、前記炭化処理炉の両端及び長さ方向の中間領域に内部空間を複数に仕切る仕切シャッターが所定の制御下で開閉自在に設けた構成をなし、該仕切られた複数個の独立内部空間のそれぞれに前記供給管部から過熱水蒸気が供給され、前記独立内部空間毎に過熱水蒸気の温度が相違するように制御された構成である。 The technique described in Patent Document 1 includes a storage container for storing organic substances, a transfer conveyor for transferring the storage container, a carbonization treatment furnace composed of tubular bodies having openings at both ends in the length direction, and superheated steam. A generator and a supply pipe portion for supplying superheated steam generated by the superheated steam generator to the inside of the carbonization treatment furnace are provided, and a plurality of internal spaces are provided at both ends of the carbonization treatment furnace and in an intermediate region in the length direction. A partition shutter is provided so as to be openable and closable under a predetermined control, and superheated steam is supplied from the supply pipe portion to each of the plurality of partitioned independent internal spaces, and superheated steam is supplied to each of the independent internal spaces. The configuration is controlled so that the temperature of the water vapor is different.

独立内部空間毎に温度が相違するのは、処理対象物の中には食物残さのほか木材、プラスチック、金属といった様々な物質が含まれていることを考慮し、これらを温度帯によって処理する構成としたものである。上流の低温域では食物残さや木材を炭化処理して炭として回収するほか、プラスチックや基盤、タイヤといった樹脂系の処理対象物は所定の温度で処理することで蒸留気化して油分を回収し、金属類についてもこれに適した温度で溶融回収し、資源の再利用をも図る技術である。 The reason why the temperature differs for each independent interior space is that the treatment target contains various substances such as wood, plastic, and metal in addition to food residue, and these are treated according to the temperature range. It is the one. In the low temperature area upstream, food residue and wood are carbonized and recovered as charcoal, and resin-based processing objects such as plastics, substrates, and tires are distilled and vaporized to recover oil by treating them at a predetermined temperature. This is a technology for reusing resources by melting and recovering metals at a temperature suitable for this.

該技術によれば、独立内部空間毎に所定の温度に制御された過熱水蒸気を発生させるべく、装置の運転中は各水蒸気発生装置及びこれに付随する各種機器を稼動させ続けなければならない。例えば、前記独立内部空間を７つ設けて、各独立内部空間を上流側から１５０℃、３００℃、４５０℃、６００℃、４５０℃、３００℃、１５０℃と制御して炭化処理を行うこととした場合、該７つの独立内部空間毎に各水蒸気発生装置及びこれに付随する各種機器を稼動させて前記所定温度の過熱水蒸気を、前記供給管部を介してそれぞれ供給することとなる。炭化処理を連続稼働することで処理効率の更なる向上を目指す該技術としては、燃料コストの低減が新たな課題として指摘されていた。 According to the technique, in order to generate superheated steam controlled to a predetermined temperature in each independent internal space, each steam generator and various devices associated therewith must be continuously operated during the operation of the device. For example, seven independent internal spaces are provided, and each independent internal space is controlled to 150 ° C., 300 ° C., 450 ° C., 600 ° C., 450 ° C., 300 ° C., and 150 ° C. from the upstream side to perform carbonization treatment. In this case, each steam generator and various devices associated therewith are operated in each of the seven independent internal spaces to supply superheated steam at a predetermined temperature via the supply pipe section. It has been pointed out that reduction of fuel cost is a new issue as the technology aiming at further improvement of processing efficiency by continuously operating carbonization treatment.

そこで、本発明者は、一連の処理工程において必然的に生じる過熱水蒸気の有効利用、即ち、過熱水蒸気の循環利用を行うことで効率的な連続運転が可能な技術を提供することを目的とする。
Therefore, an object of the present inventor is to provide a technique capable of efficient continuous operation by effectively utilizing superheated steam inevitably generated in a series of processing steps, that is, by circulating the superheated steam. ..

The size of the hole is not particularly limited, but it is preferable that the major axis (diameter in the case of a circular shape and diagonal length in the case of a square shape) is set to 7 mm to 15 mm. By providing such a mounting plate, it is possible to prevent a slightly large foreign matter or the like mixed in the object to be treated from moving downward from the mounting plate.
