As shown in FIG. 6, the ceramic ash manufacturing apparatus 100 includes a cylindrical heating furnace 119 having a heat insulating structure, and a lid 120 disposed on the heating furnace 119 via a first opening / closing door 112. And a drying chamber 121. The heating furnace 119 has an inlet 113 for receiving an object to be processed in the ceiling 111, and an inlet 115, 115 a for taking in air that has passed a magnetic field in the side wall 114 below the central position in the height direction.

　ところで、上記従来のセラミック灰の製造装置１００では、排気口１１６には二次燃焼室１５２が設けられ、排ガス中の煤、有害成分、悪臭成分を燃焼処理して除去するようにしているが、これらの燃焼処理には別途加熱のための燃料が必要となる。また、燃焼処理では排ガス中の煤、有害成分、悪臭成分を完全に除去することが難しいという問題がある。 By the way, in the conventional ceramic ash manufacturing apparatus 100, the exhaust port 116 is provided with a secondary combustion chamber 152, and the soot, harmful components, and malodorous components in the exhaust gas are burned and removed. These combustion processes require fuel for heating separately. In addition, there is a problem that it is difficult to completely remove soot, harmful components, and malodorous components in the exhaust gas by the combustion treatment.
　そこで、本発明においては、生ごみ、廃木材や廃プラスチック等の有機性廃棄物等の被処理物を熱分解する熱分解装置などから排出される排気に含まれる煤、有害成分や悪臭成分の燃焼処理に代わる方式により脱煙脱臭を行うことが可能な脱煙脱臭装置を提供することを目的とする。 Therefore, in the present invention, soot, harmful components, and malodorous components contained in exhaust gas discharged from a thermal decomposition apparatus that thermally decomposes an object to be treated such as organic waste such as garbage, waste wood, and waste plastic. An object of the present invention is to provide a smoke removal deodorization apparatus capable of performing smoke removal and deodorization by a method that replaces the combustion treatment.
　本発明の脱煙脱臭装置は、排気路に接続される脱煙脱臭装置であって、排気路内を流れる排気に対して水を噴霧する水霧処理部を有するものである。これにより、排気路内を流れる排気に噴霧された水霧により排気内に含まれる煤、有害成分や悪臭成分が除去され、脱煙脱臭が行われる。 The smoke removal deodorization apparatus of the present invention is a smoke removal deodorization apparatus connected to an exhaust passage, and has a water fog treatment section that sprays water on the exhaust flowing in the exhaust passage. Thereby, the soot, harmful components, and malodorous components contained in the exhaust gas are removed by the water mist sprayed on the exhaust gas flowing in the exhaust passage, and the smoke is removed.

　図１は本発明の実施の形態における熱分解装置の構成を示す概略断面図、図２は図１のＩＩ－ＩＩ線断面図である。 FIG. 1 is a schematic cross-sectional view showing a configuration of a thermal decomposition apparatus according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along the line II-II in FIG.
　図１において、本発明の実施の形態における熱分解装置１は、被処理物Ｍ０が収容される材料タンク２と、材料タンク２から供給される被処理物Ｍ０を処理する処理炉３とを有する。処理炉３は円筒状であり、上部に材料タンク２から供給される被処理物Ｍ０（Ｍ１）を乾燥する乾燥部３Ａを、下部に乾燥部３Ａにおいて乾燥された被処理物Ｍ１（Ｍ２）を熱分解する熱分解部３Ｂを有する。処理炉３の壁１０内には断熱材１１が充填されている。なお、本実施形態における熱分解装置１が処理する被処理物Ｍ０は、生ごみ、廃木材や廃プラスチック等の有機性廃棄物等である。 In FIG. 1, a thermal decomposition apparatus 1 according to an embodiment of the present invention includes a material tank 2 in which an object to be processed M0 is accommodated, and a processing furnace 3 for processing the object to be processed M0 supplied from the material tank 2. . The processing furnace 3 has a cylindrical shape, and a drying unit 3A for drying the processing object M0 (M1) supplied from the material tank 2 is provided at the upper part, and a processing object M1 (M2) dried in the drying part 3A is provided at the lower part. It has a thermal decomposition part 3B for thermal decomposition. A heat insulating material 11 is filled in the wall 10 of the processing furnace 3. In addition, the to-be-processed object M0 which the thermal decomposition apparatus 1 in this embodiment processes is organic wastes, such as garbage, waste wood, and a waste plastic.
　乾燥部３Ａは、円筒体１２内に上下方向に間隔を設けて配置された複数の棚３０を有し、熱分解部３Ｂから上昇した熱により棚３０上の被処理物Ｍ１を乾燥するものである。なお、本実施形態においては、乾燥部３Ａにおいて炭化まで行うが、炭化まで行わない場合もある。各棚３０は高温耐熱ステンレス板の上面を耐火セメントによって覆うことにより形成されている。棚３０は、図２に示すように、それぞれの中央部から外側に向かって放射状に形成された複数の間隙３０Ａを有する。各段の棚３０の間隙３０Ａは平面視で重ならない位置となるように配設されている。 The drying unit 3A has a plurality of shelves 30 arranged in the cylindrical body 12 at intervals in the vertical direction, and dries the workpiece M1 on the shelves 30 by the heat rising from the thermal decomposition unit 3B. is there. In the present embodiment, carbonization is performed in the drying unit 3A, but there are cases where carbonization is not performed. Each shelf 30 is formed by covering the upper surface of the high-temperature heat-resistant stainless steel plate with fire-resistant cement. As shown in FIG. 2, the shelf 30 has a plurality of gaps 30 </ b> A that are radially formed from the respective central portions toward the outside. The gaps 30A of the shelves 30 in each stage are arranged so as not to overlap in plan view.
　また、本実施形態においては、上下の棚３０の間隔は２０ｃｍ～３０ｃｍ程度とし、各棚３０の間隙３０Ａは棚３０の面積よりも小さくして、上下の棚３０間の蓄熱効果を上げている。また、相互の棚３０の下面に露出された高温耐熱ステンレス板により熱を反射させることで、棚３０上の被処理物Ｍ１の乾燥炭化を早めている。 In this embodiment, the interval between the upper and lower shelves 30 is about 20 cm to 30 cm, and the gap 30A between the shelves 30 is smaller than the area of the shelves 30 to increase the heat storage effect between the upper and lower shelves 30. . Further, the heat is reflected by the high-temperature heat-resistant stainless steel plate exposed on the lower surfaces of the shelves 30 to accelerate the dry carbonization of the workpiece M1 on the shelves 30.
　また、乾燥部３Ａは、複数の棚３０のそれぞれの上部で複数の棚３０の中央部回りに回転する複数のアーム３１からなる第１アーム群を有する。第１アーム群は、各アーム３１が各棚３０上でそれぞれ回転することで、棚３０上の被処理物Ｍ１を乾燥炭化しながら、複数の間隙３０Ａから下段の棚３０へ順次落としていくものである。また、乾燥部３Ａの上部には壁１０を貫通して処理炉３内の排気を行う排気路６が設けられている。 Further, the drying unit 3A includes a first arm group including a plurality of arms 31 that rotate around the central portions of the plurality of shelves 30 at the upper portions of the plurality of shelves 30, respectively. In the first arm group, each arm 31 is rotated on each shelf 30 to sequentially drop the workpiece M1 on the shelf 30 from the plurality of gaps 30A to the lower shelf 30 while drying and carbonizing. It is. In addition, an exhaust passage 6 that exhausts the inside of the processing furnace 3 through the wall 10 is provided in the upper part of the drying unit 3A.
　さらに、乾燥部３Ａの円筒体１２の周囲には、熱分解部３Ｂから上昇した熱を利用して蒸気を発生させるための蒸気発生パイプ４が螺旋状に設けられている。この蒸気発生パイプ４の入口４Ａおよび出口４Ｂには、例えば蒸気発電機（図示せず。）が接続される。 Furthermore, around the cylindrical body 12 of the drying unit 3A, a steam generation pipe 4 for generating steam by using the heat raised from the thermal decomposition unit 3B is provided in a spiral shape. For example, a steam generator (not shown) is connected to the inlet 4A and the outlet 4B of the steam generating pipe 4.
　熱分解部３Ｂは、熱分解部３Ｂ内を上下方向に分割するロストル３２と、ロストル３２の上下で熱分解部３Ｂの中央部周りにそれぞれ回転する複数のアーム３３からなる第２アーム群を有する。第２アーム群は、各アーム３３の回転により熱分解部３Ｂ内の被処理物Ｍ２を攪拌して、その熱分解を促進する。また、ロストル３２上で熱分解された被処理物Ｍ２はロストル３２の格子の目から熱分解部３Ｂの下部へ落下する。 The thermal decomposition unit 3B has a second arm group including a rooster 32 that divides the interior of the thermal decomposition unit 3B in the vertical direction and a plurality of arms 33 that rotate around the center of the thermal decomposition unit 3B above and below the rooster 32, respectively. . The second arm group promotes the thermal decomposition by stirring the workpiece M2 in the thermal decomposition unit 3B by the rotation of each arm 33. Moreover, the to-be-processed object M2 thermally decomposed on the rooster 32 falls from the lattice of the rooster 32 to the lower part of the pyrolyzing part 3B.
　また、熱分解部３Ｂには、ロストル３２の上下に、それぞれ空気を取り入れるコック付き空気吸入口３４と、被処理物Ｍ２に点火するための点火用バーナ３５と、炉内の高温空気を攪拌するためのファン３６とを備えている。点火用バーナ３５は運転初期に約１５分程度被処理物Ｍ２の点火に使用され、点火後は熱分解部３Ｂ内の被処理物Ｍ２が継続的に熱分解する。コック付き空気吸入口３４は、熱分解部３Ｂ内の被処理物Ｍ２が継続的に熱分解するように低酸素状態を維持するために使用される。低酸素状態では、被処理物Ｍ２は酸化（燃焼）に移行することなく、熱分解が進行する。 The pyrolysis unit 3B agitates the air inlet 34 with a cock for taking in air above and below the rooster 32, an ignition burner 35 for igniting the workpiece M2, and high-temperature air in the furnace. Fan 36 is provided. The ignition burner 35 is used to ignite the workpiece M2 for about 15 minutes in the initial stage of operation. After the ignition, the workpiece M2 in the thermal decomposition unit 3B is continuously pyrolyzed. The cocked air inlet 34 is used to maintain a low oxygen state so that the workpiece M2 in the thermal decomposition unit 3B is thermally decomposed continuously. In the low oxygen state, the object to be processed M2 undergoes thermal decomposition without shifting to oxidation (combustion).
　また、処理炉３内には、乾燥部３Ａから熱分解部３Ｂまで鉛直方向に延びる回転軸５を有する。回転軸５は処理炉３の上方の材料タンク２内に設けられたモータ５０により回転駆動される。上述の第１アーム群および第２アーム群は、この回転軸５の周りに固定され、回転軸５とともに回転する。 Further, the processing furnace 3 has a rotating shaft 5 extending in the vertical direction from the drying unit 3A to the thermal decomposition unit 3B. The rotating shaft 5 is rotationally driven by a motor 50 provided in the material tank 2 above the processing furnace 3. The first arm group and the second arm group described above are fixed around the rotating shaft 5 and rotate together with the rotating shaft 5.
　上記構成の熱分解装置１では、生ごみ、廃木材や廃プラスチック等の有機性廃棄物等の被処理物Ｍ０は、材料タンク２から処理炉３内へ供給され、熱分解部３Ｂから上昇した熱により乾燥部３Ａにおいて乾燥炭化処理される。このとき、被処理物Ｍ１は、乾燥部３Ａ内に上下方向に間隔を設けて配置された複数の棚３０上でそれぞれ第１アーム群のアーム３１により回転され、複数の棚３０上で順次乾燥炭化されつつ、各棚３０に放射状に形成された複数の間隙３０Ａから落下する。これにより、被処理物Ｍ１は乾燥部３Ａにおいて短時間で効率良く乾燥炭化される。 In the thermal decomposition apparatus 1 configured as described above, an object to be processed M0 such as organic waste such as garbage, waste wood and waste plastic is supplied from the material tank 2 into the processing furnace 3 and rises from the thermal decomposition unit 3B. Dry carbonization is performed in the drying unit 3A by heat. At this time, the object to be processed M1 is rotated by the arms 31 of the first arm group on the plurality of shelves 30 arranged at intervals in the vertical direction in the drying unit 3A, and sequentially dried on the plurality of shelves 30. While being carbonized, it falls from a plurality of gaps 30 </ b> A formed radially on each shelf 30. Thereby, the to-be-processed object M1 is dry carbonized efficiently in the drying part 3A in a short time.
　そして、乾燥部３Ａにおいて乾燥炭化された被処理物Ｍ１は、続けて下部の熱分解部３Ｂにおいて熱分解される。熱分解部３Ｂでは、コック付き空気吸入口３４により低酸素状態が維持されるように空気が吸入されることで、熱分解部３Ｂ内の被処理物Ｍ２は酸化（燃焼）に移行することなく、熱分解が進行する。すなわち、酸素濃度の薄い状態では空気の大部分が窒素となり、熱分解部３Ｂ内は低酸素状態で燃焼が抑制され、熱分解（蒸し焼き状態）が進行する。 And the to-be-processed object M1 dry-carbonized in the drying part 3A is thermally decomposed in the lower thermal decomposition part 3B continuously. In the pyrolysis section 3B, air is sucked so that the low oxygen state is maintained by the air inlet 34 with a cock, so that the object M2 in the pyrolysis section 3B does not shift to oxidation (combustion). Thermal decomposition proceeds. That is, in a state where the oxygen concentration is low, most of the air becomes nitrogen, and combustion in the pyrolysis portion 3B is suppressed in a low oxygen state, and thermal decomposition (steamed state) proceeds.
　このとき、低酸素状態中の酸素分子は、燃焼（酸化）で炭素分子と化合することなく、着火により燃焼を始めた被処理物Ｍ２（有機物）の分子構造体に並進状態で衝突することにより、衝突時のポテンシャルエネルギが熱エネルギに変換され、それぞれの有機物特有の臨界温度付近（低温プラズマ状態）で熱イオン分解（化学反応を伴う分子動力学）を始める。一方、この熱イオン分解に関わらなかった酸素分子は、有機物が熱イオン分解で徐々に炭素（Ｃ）や窒素（Ｎ）などのセラミックス（灰）化される過程で、酸素分子のファンデルワールス力とその物質の壁が持っているポテンシャルエネルギで互いに引き合うことにより、また、プラズマ状態で生起する電磁界中で酸素分子が格子状（梯子状）に整列した状態で内部に閉じ込められる。これにより、強磁性を持つ磁性セラミックスが生成される。 At this time, oxygen molecules in the low oxygen state do not combine with carbon molecules by combustion (oxidation), and collide with the molecular structure of the object to be processed M2 (organic matter) that started combustion by ignition in a translational state. The potential energy at the time of collision is converted into thermal energy, and thermal ion decomposition (molecular dynamics with chemical reaction) starts near the critical temperature peculiar to each organic substance (low temperature plasma state). On the other hand, the oxygen molecules that were not involved in the thermal ion decomposition, the organic matter is gradually converted into ceramics (ash) such as carbon (C) and nitrogen (N) by the thermal ion decomposition, van der Waals force of oxygen molecules By attracting each other with the potential energy possessed by the wall of the substance, oxygen molecules are confined in a lattice (ladder) state in an electromagnetic field generated in a plasma state. Thereby, magnetic ceramics having ferromagnetism are generated.
　熱分解部３Ｂのロストル３２上部では、ファン３６により高温空気が攪拌されながら、乾燥部３Ａにおいて乾燥炭化された被処理物Ｍ２がアーム３３により攪拌されて熱分解処理が促進され、炭化状態から磁性灰化が進行し、セラミック灰へ変化する。この熱分解処理では、被処理物Ｍ２の含有成分はそのままセラミック灰に残り、水分のみが蒸発する。被処理物Ｍ２がセラミック灰に変わると、容積が減少するため、セラミック灰に変わった被処理物Ｍ２の上方の被処理物Ｍ２は順次下方に移動する。 At the upper part of the rooster 32 of the thermal decomposition part 3B, the high temperature air is stirred by the fan 36, while the workpiece M2 dried and carbonized in the drying part 3A is stirred by the arm 33 and the thermal decomposition process is promoted. Ashing proceeds and changes to ceramic ash. In this thermal decomposition treatment, the components contained in the workpiece M2 remain in the ceramic ash as it is, and only moisture evaporates. When the object to be processed M2 is changed to ceramic ash, the volume is reduced, so that the object to be processed M2 above the object to be processed M2 changed to ceramic ash sequentially moves downward.
　こうして生成されたセラミック灰は粉末状であるため、ロストル３２の空隙からロストル３２下部に落下する。ロストル３２下部では、ファン３６により高温空気が攪拌されながら、落下した被処理物Ｍ２がロストル３２下部のアーム３３により攪拌され、さらに熱分解処理が促進されて、さらに磁性化が進んだセラミック灰となる。 Since the produced ceramic ash is in a powder form, it falls from the void of the rooster 32 to the lower portion of the rooster 32. At the lower part of the rooster 32, while the high-temperature air is stirred by the fan 36, the dropped workpiece M <b> 2 is stirred by the arm 33 below the rooster 32, the thermal decomposition process is further promoted, and the further magnetized ceramic ash Become.
　本実施形態における熱分解装置１では、この熱分解部３Ｂにおいて発生した熱が乾燥部３Ａに上昇し、乾燥部３Ａにおいて前述のように被処理物Ｍ１の乾燥炭化に利用されるので、被処理物を事前に乾燥することが不要となり、効率良く熱分解処理することが可能となる。また、本実施形態における熱分解装置１では、乾燥部３Ａの周囲に螺旋状に設けられた蒸気発生パイプ４によりこの被処理物Ｍ１の乾燥炭化に利用される熱の排熱を利用して蒸気を発生させ、例えば蒸気発電機により発電を行うことが可能である。さらに、おの発生させた蒸気の余熱を給湯に利用することも可能である。 In the thermal decomposition apparatus 1 in the present embodiment, the heat generated in the thermal decomposition unit 3B rises to the drying unit 3A and is used for dry carbonization of the workpiece M1 in the drying unit 3A as described above. It becomes unnecessary to dry the object in advance, and it becomes possible to efficiently perform the thermal decomposition treatment. Further, in the thermal decomposition apparatus 1 according to the present embodiment, steam is generated by utilizing the exhaust heat of heat used for dry carbonization of the workpiece M1 by the steam generation pipe 4 provided spirally around the drying unit 3A. Can be generated, for example, by a steam generator. Furthermore, it is also possible to use the remaining heat of the generated steam for hot water supply.
