以下、添付図面を参照しつつ、本発明の実施形態による亜臨界水処理装置１０について説明する。
亜臨界水処理装置１０は、図１に示したように、内部に、原料である有機系の処理物を収容する閉鎖空間Ｓ１を有する密閉容器１２と、この密閉容器内の原料を攪拌する攪拌手段３０と、前記処理物を亜臨界水処理するための高温高圧の蒸気を噴出する蒸気噴出手段１４を備えている。前記密閉容器１２は、両側端部の直径が中央部の直径より大きくされた横方向回転軸を回転中心とした回転体形状で形成された形態に形成されている。具体的には、直径が両側端部から中央部へ向け順次拡径されて樽状に形成された横長ドラム体（回転楕円体）や球体の形状とされるのが好ましい。要は、その下面が左右方向中心に向かって徐々に斜め下方に傾斜している形状であれば、どのような形状であってもよいが、上記横長ドラム体であることが最も好ましい。この理由から以下の説明では、密閉容器を横長ドラム体として説明する。 Hereinafter, the sub-critical water treatment apparatus 10 according to the embodiment of the present invention will be described with reference to the accompanying drawings.
As shown in FIG. 1, the sub-critical water treatment apparatus 10 has a closed container 12 having a closed space S1 for accommodating an organic processed product as a raw material, and stirring the raw material in the closed container. The means 30 and the steam ejection means 14 for ejecting high-temperature and high-pressure steam for subcritical water treatment of the treated product are provided. The closed container 12 is formed in a form formed in a rotating body shape centered on a lateral rotation axis in which the diameters of both end portions are larger than the diameter of the central portion. Specifically, it is preferably in the shape of a horizontally long drum body (spheroidal body) or a sphere formed in a barrel shape by sequentially expanding the diameter from both side end portions to the central portion. In short, any shape may be used as long as the lower surface thereof is gradually inclined downward toward the center in the left-right direction, but the horizontally long drum body is most preferable. For this reason, in the following description, the closed container will be described as a horizontally long drum body.

前記攪拌手段３０は、前記横長ドラム体内を横方向に延び、両端において、前記横長ドラム体の両側端部に軸支された回転軸２８と、この回転軸に設けられた複数の攪拌羽根４８を有している。撹拌羽根４８の回転軸２８から羽根先端までの長さは、密閉容器１２の横長ドラム体の樽型形状に対応して、回転軸２８の長手方向の中央位置で長く、両端側に行くにしたがって次第に短くなるように形成されている。 The stirring means 30 extends laterally in the horizontally long drum body, and at both ends, a rotating shaft 28 pivotally supported on both side ends of the horizontally long drum body and a plurality of stirring blades 48 provided on the rotating shaft. Have. The length from the rotating shaft 28 of the stirring blade 48 to the tip of the blade is long at the center position in the longitudinal direction of the rotating shaft 28, corresponding to the barrel shape of the horizontally long drum body of the closed container 12, and increases toward both ends. It is formed so as to become shorter and shorter.

前記回転軸２８は、前記蒸気噴出手段１４の一部をなす内部空間を備えた中空管で形成されており、その意味で、蒸気噴出管としても作用する。以下、この蒸気噴出管にも、符号２８を付することがある。 The rotating shaft 28 is formed of a hollow pipe having an internal space that forms a part of the steam ejection means 14, and in that sense, also acts as a steam ejection pipe. Hereinafter, the steam ejection pipe may also be designated by reference numeral 28.

前記蒸気噴出手段１４は、前記蒸気噴出管２８の一端、または両端から、前記内部空間内に蒸気を供給するための蒸気供給手段を備え、この蒸気供給手段は、ボイラー等の蒸気発生装置４６と、蒸気発生装置４６から蒸気噴出管２８内に蒸気を供給する蒸気送管４７を含む。蒸気噴出管２８には、該蒸気噴出管に供給された蒸気を、前記密閉容器内に噴出するための多数の噴出孔４４が形成されている。後に説明するが、この多数の噴出孔４４は、前記密閉容器の横長ドラム体の直径が大きくなるにつれて、単位面積当たりの前記噴出孔のトータル開口面積を大きくされている。 The steam ejection means 14 includes a steam supply means for supplying steam into the internal space from one end or both ends of the steam ejection pipe 28, and the steam supply means includes a steam generator 46 such as a boiler. , Includes a steam delivery pipe 47 that supplies steam from the steam generator 46 into the steam ejection pipe 28. The steam ejection pipe 28 is formed with a large number of ejection holes 44 for ejecting the steam supplied to the steam ejection pipe into the closed container. As will be described later, in the large number of ejection holes 44, the total opening area of the ejection holes per unit area is increased as the diameter of the horizontally long drum body of the closed container is increased.

前記密閉容器１２は、その底側に設けられ開閉機構２６を有する排出口１６と、排出口１６からの直接排出操作のみで処理された処理物と液体とを分離して回収する分離回収手段１８を備えている。密閉容器の下面が排出口へ向けて下り傾斜となっているので、処理された処理物の固形分や液体は、下面側に設けられている排出口１６から重力を利用して排出される。 The closed container 12 has a discharge port 16 provided on the bottom side thereof and having an opening / closing mechanism 26, and a separation / recovery means 18 for separating and recovering a processed product and a liquid treated only by a direct discharge operation from the discharge port 16. It has. Since the lower surface of the closed container is inclined downward toward the discharge port, the solid content and liquid of the treated product are discharged from the discharge port 16 provided on the lower surface side by gravity.

また、分離回収手段１８は、密閉容器１２の閉鎖空間Ｓ１とは異なる他の閉鎖空間Ｓ２を有し、排出口１６を介して該密閉容器１２内部に連通する液体の回収部５０と、密閉容器１２内の液体のみを排出口１６を介して自然流下により回収部５０へ回収させる自然流下回収機構５２と、を有することとしてもよい。排出口１６付近で処理された固形の処理物は密閉容器１２内にそのまま残り、液体のみが重力を利用して回収部５０へ自然流下することにより、処理物と液体とを分離回収できる。回収部５０の構成は、例えば、金属製タンクや立体多角形状の箱体、管状体等、液体を回収する閉鎖空間Ｓ２を有するものであれば任意のものでもよい。収容部を複数個形成してもよい。 Further, the separation / recovery means 18 has another closed space S2 different from the closed space S1 of the closed container 12, and has a liquid collecting unit 50 communicating with the inside of the closed container 12 via the discharge port 16 and a closed container. It may have a natural flow recovery mechanism 52 for collecting only the liquid in 12 to the recovery unit 50 by natural flow through the discharge port 16. The solid processed product treated near the discharge port 16 remains as it is in the closed container 12, and only the liquid naturally flows down to the collection unit 50 using gravity, so that the processed product and the liquid can be separated and recovered. The structure of the recovery unit 50 may be arbitrary as long as it has a closed space S2 for collecting liquid, such as a metal tank, a three-dimensional polygonal box body, or a tubular body. A plurality of accommodating portions may be formed.

本実施形態では、密閉容器１２は、支持脚１３で地面からある程度の高さに配置されるように支持されている。前述のように、密閉容器１２は、その径が左右方向中央部から左右両端側の端壁１２ａ側に向けて次第に縮径された横倒し樽型形状に形成されている。密閉容器１２は、例えば、耐熱耐圧性を有するように金属板を加工して形成され、処理物を０．５〜数ｍ^３収容できる程度の大きさで設けられている。密閉容器１２には、中央部の上方に投入部２０が、中央部の底側に排出部２２がそれぞれ設けられており、それぞれ開閉機構２４，２６により開閉されるように設けられている。 In the present embodiment, the closed container 12 is supported by the support legs 13 so as to be arranged at a certain height from the ground. As described above, the closed container 12 is formed in a sideways barrel shape in which the diameter is gradually reduced from the central portion in the left-right direction toward the end walls 12a on both the left and right ends. Sealed container 12 is formed, for example, by forming a metal plate to have a heat pressure resistance, it is provided in a size that can be 0.5 number m ³ housing a processing object. The closed container 12 is provided with a charging portion 20 above the central portion and a discharging portion 22 on the bottom side of the central portion, respectively, and is provided so as to be opened and closed by the opening / closing mechanisms 24 and 26, respectively.

なお、密閉容器１２には、内部圧力が設定値よりも高くなると内部蒸気を開放させる、例えば設定圧を調整可能な安全弁３２が設けられている。また、安全弁３２に接続された排気用管の途中には、消音・消臭装置３４が設けられており、安全弁３２を介して排気される蒸気は消音消臭されて、外気側に排出される。 The closed container 12 is provided with a safety valve 32 that releases the internal steam when the internal pressure becomes higher than the set value, for example, the set pressure can be adjusted. Further, a muffling / deodorizing device 34 is provided in the middle of the exhaust pipe connected to the safety valve 32, and the steam exhausted through the safety valve 32 is deodorized and deodorized and discharged to the outside air side. ..

本実施形態では、排出口１６は、図１に示すように、密閉容器１２の左右中央部の底面側に開口されており、処理物の排出方向を下方にして設けられている。本実施形態では、排出口１６の径は、例えば、閉鎖空間Ｓ１の容積が２ｍ^３の場合、３００ｍｍ程度に設けられている。本実施形態では、排出口１６には、下方に突設された排出筒３６が接続されて処理された処理物の排出経路Ｒ１を形成しているとともに、該排出経路Ｒ１の途中に設けられて排出口１６を開閉する開閉機構２６が設けられている。すなわち、本実施形態では、排出部２２は、排出口１６と、排出筒３６と、開閉機構２６と、を含む構成となっている。なお、密閉容器の排出口からボールバルブまでの距離は、密閉容器のサイズや、処理後の排出物の状態（液体状、固体状）に鑑みて設定することができる。この設定は、特に短縮することが好ましく、短縮した場合、排出通路のバルブまでの空間に、処理中に処理物が溜まり、処理されない状態となることが防止される。したがって、上記の観点からは、排出経路Ｒ１における開閉機構２６の設置位置は、密閉容器１２の排出口１６にできるだけ近接していることが望ましい。
前記本実施形態では、開閉機構２６は、例えば、中心に排出経路Ｒ１に連通する貫通孔が設けられたボール状の弁体を排出経路に対して直交方向に設けられた回転軸の回りに回転させることにより該排出経路Ｒ１を開閉するボールバルブ等の開閉弁からなる。密閉容器１２の上記の形状から、重力により内部の処理物は排出口１６が設けられている中央部に向けて集まりやすく、開閉機構２６を開くだけで簡便に処理物を排出口１６から排出させることができる。 In the present embodiment, as shown in FIG. 1, the discharge port 16 is opened on the bottom surface side of the left and right central portions of the closed container 12, and is provided with the discharge direction of the processed material facing downward. In the present embodiment, the diameter of the discharge port 16 is provided to be about 300 mm ^{, for example, when the volume of the closed space S1 is 2 m 3.} In the present embodiment, the discharge port 16 is connected to a discharge cylinder 36 projecting downward to form a discharge path R1 for the processed product, and is provided in the middle of the discharge path R1. An opening / closing mechanism 26 for opening / closing the discharge port 16 is provided. That is, in the present embodiment, the discharge unit 22 includes a discharge port 16, a discharge cylinder 36, and an opening / closing mechanism 26. The distance from the discharge port of the closed container to the ball valve can be set in consideration of the size of the closed container and the state of the discharged product (liquid or solid) after processing. This setting is particularly preferably shortened, and when it is shortened, it is possible to prevent the processed material from accumulating in the space up to the valve of the discharge passage and not being processed. Therefore, from the above viewpoint, it is desirable that the installation position of the opening / closing mechanism 26 in the discharge path R1 is as close as possible to the discharge port 16 of the closed container 12.
In the present embodiment, for example, the opening / closing mechanism 26 rotates a ball-shaped valve body having a through hole communicating with the discharge path R1 in the center around a rotation axis provided in a direction orthogonal to the discharge path. It is composed of an on-off valve such as a ball valve that opens and closes the discharge path R1 by allowing the discharge path R1 to open and close. Due to the above-mentioned shape of the closed container 12, the processed material inside is easily collected toward the central portion where the discharge port 16 is provided due to gravity, and the processed material is easily discharged from the discharge port 16 simply by opening the opening / closing mechanism 26. be able to.

投入部２０は、本実施形態では、密閉容器１２の上側に投入口４２が開口されており、投入口４２には上方へ突設された投入筒４３が取り付けられ、投入筒４３内を開閉するように例えばボールバルブ等の開閉機構２４が設けられている。開閉機構２４を介して、投入口を開いて処理物を密閉容器内に投入でき、処理時には閉鎖して密閉容器１２内の閉鎖空間Ｓ１の閉鎖状態を維持する。 In the present embodiment, the loading unit 20 has a loading port 42 opened on the upper side of the closed container 12, and a loading cylinder 43 projecting upward is attached to the loading port 42 to open and close the inside of the loading cylinder 43. As described above, for example, an opening / closing mechanism 24 such as a ball valve is provided. The input port can be opened via the opening / closing mechanism 24 to charge the processed material into the closed container, and the processed material can be closed during processing to maintain the closed state of the closed space S1 in the closed container 12.

本実施形態において、蒸気噴出手段１４は、密閉容器１２内に高温高圧の蒸気を噴出するとともに、該密閉容器１２内を高温高圧状態とし、処理物を蒸気の直接的および間接的作用により処理する。すなわち、この時、蒸気は、処理物（主として固形状の成分）を亜臨界水処理しうる高温高圧に設定される。例えば、蒸気噴出管２８から噴出される蒸気は、温度が１８０〜２５０℃、圧力が１５〜３５ａｔｍ程度に設定されている。そして、密閉容器１２内を、温度１８０〜２５０℃、圧力１５〜３５ａｔｍ程度にするようになっている。蒸気噴出管２８（すなわち、回転軸２８）は、密閉容器１２の上下方向略中央位置で横方向に長く配置され、密閉容器の両端壁１２ａに設けられた軸受４５を介して回転自在に軸支されている。すなわち、蒸気噴出管２８は、横軸周りに回転しながら放射状に蒸気を噴出しつつ蒸気を処理物に直接に当てるようになっている。なお、蒸気噴出管２８は、モータ等の回転駆動装置５１からチェーン等を介して回転駆動力を得て回転するようになっている。 In the present embodiment, the steam ejection means 14 ejects high-temperature and high-pressure steam into the closed container 12, puts the inside of the closed container 12 into a high-temperature and high-pressure state, and treats the processed material by the direct and indirect actions of the steam. .. That is, at this time, the steam is set to a high temperature and high pressure at which the treated product (mainly a solid component) can be treated with sub-critical water. For example, the temperature of the steam ejected from the steam ejection pipe 28 is set to about 180 to 250 ° C. and the pressure is set to about 15 to 35 atm. Then, the temperature inside the closed container 12 is set to about 180 to 250 ° C. and the pressure is set to about 15 to 35 atm. The steam ejection pipe 28 (that is, the rotating shaft 28) is arranged long in the horizontal direction at a substantially central position in the vertical direction of the closed container 12, and is rotatably supported via bearings 45 provided on both end walls 12a of the closed container. Has been done. That is, the steam ejection pipe 28 is adapted to directly hit the processed object while ejecting steam radially while rotating around the horizontal axis. The steam ejection pipe 28 rotates by obtaining a rotational driving force from a rotational driving device 51 such as a motor via a chain or the like.

撹拌手段３０は、密閉容器内で処理される処理物を撹拌して、処理物をむらなく、かつ迅速に処理するための手段であり、上記したように、回転軸２８と、該回転軸２８に取り付けられ同回転軸の周方向に広がる部位を有する撹拌羽根４８と、を含む。撹拌羽根４８は、回転軸４９の軸方向略中央位置で互いに逆巻きに設けられた、右巻き螺旋羽根４８ａと、左巻き螺旋羽根４８ｂと、で形成されている。撹拌羽根４８は、回転軸から羽根先端までの長さが左右中央部から両端側に向けて次第に縮径されるように設けられている。これにより密閉容器１２の横倒し樽型形状に対応して処理物を確実に撹拌できる。さらに、羽根先端と密閉容器１２の内壁との間にある程度の隙間Ｈを形成するように設けられている。螺旋羽根４８ａ、４８ｂは、処理物を中央部から両端壁側に向けて搬送しつつ、固形状の処理物を破砕しながら処理物を撹拌する。なお、本実施形態では、撹拌手段により、処理物は最終的に、例えば、０．３〜０．８ｍｍ程度に破砕されるように設けられている。撹拌羽根４８により両端壁１２ａ側に搬送された処理物は、該端壁１２ａ側で後から搬送されてくる処理物によって押送され、密閉容器１２の内壁に沿いつつ隙間Ｈを介してから中央に戻るように搬送されるようになっている。なお、撹拌手段３０は、本実施形態のものに限らず、例えば、回転軸に取り付けられた複数の板状や翼状の撹拌羽根体やロッド体で撹拌する構成、蒸気等の圧力流体で撹拌する構成等その他任意の構成でもよい。また、処理物の破砕後の大きさは、任意に設定してもよい。 The stirring means 30 is a means for stirring the processed material to be processed in the closed container and processing the processed material evenly and quickly. As described above, the rotating shaft 28 and the rotating shaft 28 Includes a stirring vane 48, which is attached to and has a portion extending in the circumferential direction of the same rotation axis. The stirring blade 48 is formed by a right-handed spiral blade 48a and a left-handed spiral blade 48b, which are provided in opposite directions to each other at a substantially central position in the axial direction of the rotating shaft 49. The stirring blade 48 is provided so that the length from the rotation shaft to the tip of the blade is gradually reduced from the left and right central portions to both ends. As a result, the processed product can be reliably agitated corresponding to the sideways barrel shape of the closed container 12. Further, it is provided so as to form a certain gap H between the tip of the blade and the inner wall of the closed container 12. The spiral blades 48a and 48b stir the processed material while crushing the solid processed material while transporting the processed material from the central portion toward both end walls. In this embodiment, the processed product is finally crushed to, for example, about 0.3 to 0.8 mm by the stirring means. The processed material conveyed to both end walls 12a side by the stirring blade 48 is pushed by the processed material conveyed later on the end wall 12a side, and is sent to the center along the inner wall of the closed container 12 through the gap H. It is designed to be transported back. The stirring means 30 is not limited to that of the present embodiment, and is, for example, a structure in which a plurality of plate-shaped or wing-shaped stirring blades or rods attached to a rotating shaft are used for stirring, or a pressure fluid such as steam is used for stirring. Any other configuration such as a configuration may be used. Further, the size of the processed product after crushing may be arbitrarily set.

本実施形態では、上記のように密閉容器内で高温高圧下で撹拌しながら、所要時間、例えば３０〜６０分程度処理することにより、処理物が処理される。なお、上記のような処理では、例えば処理物中に含まれるＰＣＢの分解も期待できる。例えば、トランス油が混じった処理物等を処理した場合、ＰＣＢ濃度が処理前には８０ｐｐｍあったものが処理後には０．００５ｐｐｍ程度に減少したことが確認されている。密閉容器１２内には、蒸気の一部が液化したり、処理物に含まれる水分等により液体が溜まり、処理されて炭化された処理物と液体とが混在した状態となる。 In the present embodiment, the processed product is processed by processing for a required time, for example, about 30 to 60 minutes while stirring under high temperature and high pressure in a closed container as described above. In the above processing, for example, decomposition of PCB contained in the processed product can be expected. For example, it has been confirmed that when a processed product or the like mixed with transformer oil is treated, the PCB concentration of 80 ppm before the treatment is reduced to about 0.005 ppm after the treatment. In the closed container 12, a part of the vapor is liquefied, or the liquid is accumulated due to the moisture or the like contained in the processed product, and the processed product and the liquid are mixed after being treated and carbonized.

液体回収部５０は、液体回収流路５４を介して密閉容器１２の排出口１６と連通接続されている。この液体回収流路５４には、開閉機構６０が設けられており、この開閉機構６０は、密閉容器内での処理物の処理中には流路を遮断するとともに、処理後に液体のみを分離回収する際には流路を連通させるように切り替えられる。これにより、処理物と同時に処理物中に含まれる水分や蒸気が液化して処理物中の細菌や悪臭成分等を含んで状態の液体は、高温高圧の蒸気で処理させることができる。そして、処理後に分離回収される液体は、殺菌や、悪臭・有害成分の分解等された状態で回収することができ、分離回収した液体を二次処理する必要がなく、労力がかからず、時間短縮を図ることができる。 The liquid recovery unit 50 is communicated with the discharge port 16 of the closed container 12 via the liquid recovery flow path 54. The liquid recovery flow path 54 is provided with an opening / closing mechanism 60, and the opening / closing mechanism 60 shuts off the flow path during processing of the processed material in the closed container and separates and collects only the liquid after the processing. When doing so, it is switched so that the flow path is communicated. As a result, the water and steam contained in the processed product are liquefied at the same time as the processed product, and the liquid containing bacteria, malodorous components and the like in the processed product can be treated with high-temperature and high-pressure steam. The liquid separated and recovered after the treatment can be recovered in a state of being sterilized or decomposed of malodorous and harmful components, and the separated and recovered liquid does not need to be secondarily treated, and no labor is required. The time can be shortened.

液体回収流路５４は、液体導入口５８が開閉機構２６よりも排出上流側の位置に連通接続されている。よって、排出口１６の開閉機構２６を閉じた状態で、液体回収流路５４の開閉機構６０を開いて流路を連通状態にすることにより、排出口から液体を分離して回収させる。本実施形態では、液体回収流路５４は排出筒３６と直交方向に接続されており、液体の回収経路Ｒ２が処理物の排出経路Ｒ１に対して直交方向に設けられている。すなわち、開閉機構２６の閉鎖状態では、密閉容器内の処理物の堆積圧がかかる方向に対して交差方向に液体が流れるようになっている。これにより、簡単な構造で、液体導入口５８に処理物が入りにくい構造となり、液体のみを液体回収路５４に自然流下させて、液体の分離回収を良好に行なうことができる。なお、密閉容器１２内の液体が液体導入口５６へ流れる勢いが強すぎると、液体の流れの力によって処理物がともに流れされるおそれがあるので、好適には、処理された処理物を流し運ばない程度の緩やかな流れになるように、液体回収路や液体導入口等の接続構成が設定される。本実施形態では、液体回収路５４が、液体導入口５８から水平に設けられており、液体導入口への自然流下の流速が比較的低くなるように設定されている。図１の実施形態では、液体回収流路５４は、排出口１６との連通側（液体導入口側）から回収部側に向けて全体的に水平に設けられている。これにより、液体回収流路での液体の流れはスムーズに行われ、排出口から回収部へ自然流下される。液体導入口５８には、必要に応じてフィルタ等を設けることとしてもよい。 In the liquid recovery flow path 54, the liquid introduction port 58 is communicated and connected at a position on the discharge upstream side of the opening / closing mechanism 26. Therefore, with the opening / closing mechanism 26 of the discharge port 16 closed, the opening / closing mechanism 60 of the liquid recovery flow path 54 is opened to bring the flow path into a communicating state, so that the liquid is separated from the discharge port and collected. In the present embodiment, the liquid recovery flow path 54 is connected to the discharge cylinder 36 in the direction orthogonal to the discharge cylinder 36, and the liquid recovery path R2 is provided in the direction orthogonal to the discharge path R1 of the processed material. That is, in the closed state of the opening / closing mechanism 26, the liquid flows in the crossing direction with respect to the direction in which the deposition pressure of the processed material in the closed container is applied. As a result, the structure is such that the processed material does not easily enter the liquid introduction port 58 with a simple structure, and only the liquid can be naturally flowed down into the liquid recovery path 54, so that the liquid can be separated and recovered satisfactorily. If the momentum of the liquid in the closed container 12 flowing to the liquid introduction port 56 is too strong, the processed material may flow together due to the force of the liquid flow. The connection configuration of the liquid recovery path, liquid inlet, etc. is set so that the flow is gentle enough not to be carried. In the present embodiment, the liquid recovery path 54 is provided horizontally from the liquid introduction port 58, and is set so that the flow velocity of the natural flow to the liquid introduction port is relatively low. In the embodiment of FIG. 1, the liquid recovery flow path 54 is provided horizontally as a whole from the communication side with the discharge port 16 (the liquid introduction port side) toward the recovery portion side. As a result, the liquid flows smoothly in the liquid recovery flow path and naturally flows down from the discharge port to the recovery section. The liquid introduction port 58 may be provided with a filter or the like, if necessary.

さらに、図１に示すように、本実施形態では、自然流下機構５２は、液体の回収操作前に、密閉容器１２の閉鎖空間Ｓ１と回収部５０の閉鎖空間Ｓ２とを同圧に形成させる同圧形成手段６２を含む。処理後の密閉容器１２内は高圧であるから、液体回収流路では、密閉容器内に比べて低圧である回収部の閉鎖空間Ｓ２に向けて圧力差による圧送力が働く。このような圧送力が働くと液体と処理物とがともに液体回収流路５４に流れこむこととなり、液体と処理物との分離回収が困難となるとともに、処理物が液体回収流路内に詰まるおそれが高い。本実施形態のように、同圧形成手段６２により、液体の回収操作前に密閉容器１２と回収部５０との２つの閉鎖空間Ｓ１，Ｓ２を同圧にしておくことにより、該２つの閉鎖空間Ｓ１、Ｓ２の気圧の差により生じる処理物が圧送されるのを防止でき、液体の自然流下作用を利用して、処理物と分離しながら良好に回収部に回収できる。また、処理後の密閉容器内の高圧状態でも分離回収作業を行えるので、作業時間を短縮できる。 Further, as shown in FIG. 1, in the present embodiment, the natural flow mechanism 52 forms the closed space S1 of the closed container 12 and the closed space S2 of the recovery unit 50 at the same pressure before the liquid recovery operation. The pressure forming means 62 is included. Since the inside of the closed container 12 after the treatment has a high pressure, a pressure feeding force due to a pressure difference acts toward the closed space S2 of the recovery portion, which has a lower pressure than the inside of the closed container. When such a pumping force acts, both the liquid and the processed material flow into the liquid recovery flow path 54, which makes it difficult to separate and recover the liquid and the processed material and clogs the processed material in the liquid recovery flow path. There is a high risk. As in the present embodiment, the same pressure forming means 62 keeps the two closed spaces S1 and S2 of the closed container 12 and the recovery unit 50 at the same pressure before the liquid recovery operation, whereby the two closed spaces. It is possible to prevent the processed material generated by the difference in atmospheric pressure between S1 and S2 from being pumped, and by utilizing the natural flow action of the liquid, it can be satisfactorily collected in the recovery unit while being separated from the processed material. Further, since the separation and recovery work can be performed even in the high pressure state in the closed container after the treatment, the work time can be shortened.

本実施形態において、同圧形成手段６２は、排出口１６を介した液体の回収経路Ｒ２（本実施形態では液体回収流路５４）とは異なる別の経路Ｒ３で密閉容器１２の閉鎖空間Ｓ１と回収部５０の閉鎖空間Ｓ２とを連通させる同圧連通管６４を含む。同圧連通管６４は、例えば、金属製管からなり、簡単な構造でしかも効率的に２つの閉鎖空間Ｓ１，Ｓ２を同圧にできる。図１では、同圧連通管６４は、一端側が密閉容器１２の左右中央部の上端側に連通接続され、他端側を回収部５０の上端側に連通接続されている。本実施形態では、別の経路Ｒ３を形成する同圧連通管６４と密閉容器１２との連通は、密閉容器１２の上端側に設定された連通接続部６８を介して行なわれるようになっている。本実施形態では、連通接続部６８の密閉容器との接続口が下方に向けて設定されている。これにより、同圧連通管６４内に密閉容器１２内で堆積している処理物が管内に入りにくくなっており、処理物が管内に詰まるのを防止して同圧連通管の連通状態を保持し、密閉容器１２と回収部５０とを確実に同圧にさせることができる。本実施形態では、同圧連通管６４は、常時連通状態となっており、液体回収流路５４の開閉機構６０を閉じた状態では、密閉容器１２内、回収部５０、液体回収流路５４内が同じ圧力状態になる。これにより、液体回収流路５４の開閉機構６０を開いた直後にも排出口１６の液体導入口５８側で圧力差による処理物の圧送を防止できる。さらに、開閉機構６０を開いて液体が回収する際にも、密閉容器１２内と回収部５０内は常時同圧状態が保持される。したがって、回収前から回収終了後まで同圧状態となり、良好に液体のみを排出口１６から自然流下させて分離回収することができる。なお、同圧形成手段６２は、実施形態の構成に限らず任意の構成でよい。例えば、同圧形成手段６２は、回収部内を高圧にする他の高圧形成装置を設け、密閉容器内の圧力をセンサーで監視しながら回収部内の圧力を調整して、密閉容器内の圧力と同圧にするようにしてもよい。また、密閉容器内を減圧することとしてもよい。 In the present embodiment, the pressure forming means 62 meets the closed space S1 of the closed container 12 in another path R3 different from the liquid recovery path R2 (the liquid recovery flow path 54 in the present embodiment) via the discharge port 16. Includes the same pressure communication pipe 64 that communicates with the closed space S2 of the recovery unit 50. The same pressure communication pipe 64 is made of, for example, a metal pipe, and can efficiently make the two closed spaces S1 and S2 have the same pressure with a simple structure. In FIG. 1, one end side of the same pressure communication pipe 64 is communicated with the upper end side of the left and right central portions of the closed container 12, and the other end side is communicated with the upper end side of the recovery portion 50. In the present embodiment, the communication between the same pressure communication pipe 64 forming another path R3 and the closed container 12 is performed via the communication connecting portion 68 set on the upper end side of the closed container 12. .. In the present embodiment, the connection port of the communication connection portion 68 with the closed container is set to face downward. As a result, the processed material accumulated in the closed container 12 in the same pressure communication pipe 64 is less likely to enter the pipe, and the processed material is prevented from being clogged in the pipe to maintain the communication state of the same pressure communication pipe. Then, the closed container 12 and the collecting unit 50 can be surely made to have the same pressure. In the present embodiment, the same pressure communication pipe 64 is always in a communication state, and when the opening / closing mechanism 60 of the liquid recovery flow path 54 is closed, the inside of the closed container 12, the recovery unit 50, and the liquid recovery flow path 54. Is in the same pressure state. As a result, it is possible to prevent pressure feeding of the processed material due to the pressure difference on the liquid introduction port 58 side of the discharge port 16 immediately after opening the opening / closing mechanism 60 of the liquid recovery flow path 54. Further, even when the opening / closing mechanism 60 is opened to collect the liquid, the same pressure state is always maintained in the closed container 12 and the collecting unit 50. Therefore, the pressure is the same from before the recovery to after the recovery, and only the liquid can be satisfactorily flowed down from the discharge port 16 for separation and recovery. The pressure forming means 62 is not limited to the configuration of the embodiment and may have any configuration. For example, the same pressure forming means 62 is provided with another high pressure forming device for increasing the pressure inside the recovery unit, and adjusts the pressure inside the collection unit while monitoring the pressure inside the closed container with a sensor to match the pressure inside the closed container. It may be pressured. Further, the pressure inside the closed container may be reduced.

本発明においては、前記蒸気噴出管２８に多数設けられた蒸気噴出孔４４の該蒸気噴出管の単位面積当たりのトータル開口面積が、横長ドラム体の直径が大きくなるにつれて大きくなるように設定されている。
具体的には、図２に示すように、各蒸気噴出孔４４の開口径は同一であるが、蒸気噴出孔４４の配置ピッチが、蒸気噴出管の両側から、中央に向かうにつれて狭く設定されているもの、図３に示すように、蒸気噴出孔４４の開口径が、蒸気噴出管の両側から、中央に向かうにつれて大きくされているもの、図４に示されているように、
各蒸気噴出孔４４の開口径は同一であるが、蒸気噴出孔４４の単位面積当たりの配置数が、蒸気噴出管の両側から、中央に向かうにつれて多くされているもの等が挙げられるが、ようするに、密閉容器の直径が大きい中央部に向かって、噴出される蒸気の量が多くなればよい。すなわち、密閉容器内における処理物の量の分布に見合う量の蒸気が噴出・供給されればよい。 In the present invention, the total opening area per unit area of the steam ejection pipes 44 of the steam ejection holes 44 provided in the steam ejection pipe 28 is set to increase as the diameter of the horizontally long drum body increases. There is.
Specifically, as shown in FIG. 2, the opening diameters of the steam ejection holes 44 are the same, but the arrangement pitch of the steam ejection holes 44 is set narrower from both sides of the steam ejection pipe toward the center. As shown in FIG. 3, the opening diameter of the steam ejection hole 44 is increased from both sides of the steam ejection pipe toward the center, as shown in FIG.
Although the opening diameter of each steam ejection hole 44 is the same, the number of arrangements of the steam ejection holes 44 per unit area may be increased from both sides of the steam ejection pipe toward the center. It is sufficient that the amount of steam ejected toward the central portion where the diameter of the closed container is large increases. That is, it is sufficient that the amount of steam corresponding to the distribution of the amount of the processed material in the closed container is ejected and supplied.

次に、本実施形態に係る有機系処理物の処理装置の操作・作動について、簡単に説明する。
先ず、排出口１６の開閉機構２６、液体回収流路５４の開閉機構６０を閉じた状態で、密閉容器１２の投入口の開閉機構２４を開いて、例えば、２ｍ^３程度の処理物を投入する。投入口の開閉機構２４を閉じて密閉容器１２を閉鎖した状態で、該密閉容器内に蒸気噴出手段１４の蒸気噴出管２８から、例えば、２５０℃、２５ａｔｍ程度に設定された高温高圧の蒸気を、密閉容器１２の中央向かう程多量に噴出する。噴出された蒸気により、密閉容器１２内は例えば、均一に、２５０℃、２５ａｔｍ程度の高温高圧状態となる。同時に、同圧連通管６４を介して回収部５０の閉鎖空間Ｓ２は、密閉容器内と同圧状態となり、例えば、２５０℃、２５ａｔｍ程度の高温高圧状態となる。密閉容器内で高温高圧の条件下で、回転する撹拌羽根４８により処理物を撹拌、破砕させながら処理物を処理する。処理物に含まれる（あるいは付着している）病原体等は十分に滅菌されるとともに、悪臭成分等を分解しながら処理される。また、処理中では、液体回収流路の開閉機構６０により流路が遮断されているので、処理物と同時に処理物に含まれる水分も高温高圧の蒸気で処理される。このような処理を所要時間、例えば、約４０分間行なうと、処理物は、例えば、０．３〜０．８ｍｍ程度の粒状に破砕された炭状態に処理される。 Next, the operation and operation of the processing apparatus for the organic processed material according to the present embodiment will be briefly described.
First, with the opening / closing mechanism 26 of the discharge port 16 and the opening / closing mechanism 60 of the liquid recovery flow path 54 closed, the opening / closing mechanism 24 of the input port of the closed container 12 is opened, and for example, a processed material of about ^{2 m 3 is charged.} .. With the opening / closing mechanism 24 of the inlet closed and the closed container 12 closed, high-temperature and high-pressure steam set to, for example, about 250 ° C. and 25 atm is blown into the closed container from the steam ejection pipe 28 of the steam ejection means 14. , A large amount of steam is ejected toward the center of the closed container 12. Due to the ejected steam, the inside of the closed container 12 is uniformly, for example, in a high temperature and high pressure state of about 250 ° C. and 25 atm. At the same time, the closed space S2 of the recovery unit 50 is in the same pressure state as in the closed container via the same pressure communication pipe 64, and is in a high temperature and high pressure state of, for example, about 250 ° C. and 25 atm. The processed product is processed while being stirred and crushed by a rotating stirring blade 48 under high temperature and high pressure conditions in a closed container. Pathogens and the like contained (or adhered to) in the treated product are sufficiently sterilized and treated while decomposing malodorous components and the like. Further, during the treatment, since the flow path is blocked by the opening / closing mechanism 60 of the liquid recovery flow path, the moisture contained in the processed product is treated with the high-temperature and high-pressure steam at the same time as the processed product. When such a treatment is carried out for a required time, for example, about 40 minutes, the treated product is treated into a charcoal state crushed into particles of, for example, about 0.3 to 0.8 mm.

上記のように処理物を処理した後には、密閉容器１２内には処理された処理物と液体が混在した状態となっているので、分離回収手段を介して、先ず液体のみを分離回収させる。液体回収流路５４の開閉機構６０を開くと、排出口から液体回収流路内へ液体が自然流下して回収部に回収される。すなわち、本実施形態の液体回収方法では、上記のように処理物を処理する密閉容器を第１の閉鎖容器とし、密閉容器の排出口を介して連通接続されるとともに、排出口とは異なる同圧連通管を介して密閉容器１２と同圧になる回収部５０を第２の閉鎖容器とし、密閉容器と回収部とを同圧にした状態で、排出口を介して液体を自然流下させることにより、回収部に液体のみを分離回収する。密閉容器１２内と回収部５０内とが同圧であるから液体と処理物とが一緒になって圧送されることがなく、密閉容器１２内に溜まった液体の重力による自然流下により、液体のみが液体導入口５０から液体回収流路５４内へ流れる。さらに、本実施形態では、密閉容器と回収部とは同圧連通管を介して常時同圧状態であるから、処理物を処理した後、すぐに液体の分離回収を行うことができ、作業時間を短縮することができる。例えば、１５〜２０分程度放置し、液体を自然流下させて分離回収した後に、密閉容器１２の排出口１６の開閉機構２６を開いて、処理された処理物を排出する。処理された処理物は、例えば、含水率が３０％程度の状態で液体とほとんど分離した状態となっており、運搬、管理等の際にも扱いやすい状態で回収することができる。これにより、一台の装置だけで、処理物の処理と、処理物と液体とを分離して回収できる。また、液体と混ざった状態の扱いにくい処理物を外部に出す必要がなく、処理に連続して、密閉容器から直接に簡単な操作で分離回収できる。また、分離回収の構成も簡単であり、低コストで製造できる。なお、各開閉機構は、手動操作で開閉する構成でもよく、或いは電気等を用いた機械的な操作で開閉させる構成でもよい。 After the treated product is treated as described above, the treated product and the liquid are mixed in the closed container 12, so that only the liquid is first separated and recovered via the separation / recovery means. When the opening / closing mechanism 60 of the liquid recovery flow path 54 is opened, the liquid naturally flows down from the discharge port into the liquid recovery flow path and is collected by the recovery unit. That is, in the liquid recovery method of the present embodiment, the closed container for processing the processed material is set as the first closed container as described above, and the closed container is communicated and connected via the discharge port of the closed container, and is different from the discharge port. The recovery section 50, which has the same pressure as the closed container 12 via the pressure communication pipe, is used as the second closed container, and the liquid naturally flows down through the discharge port with the closed container and the recovery section at the same pressure. As a result, only the liquid is separated and recovered in the recovery section. Since the pressure inside the closed container 12 and the inside of the collecting unit 50 are the same, the liquid and the processed material are not pumped together, and only the liquid is naturally flowed by the gravity of the liquid collected in the closed container 12. Flows from the liquid introduction port 50 into the liquid recovery flow path 54. Further, in the present embodiment, since the closed container and the recovery unit are always in the same pressure state via the same pressure communication pipe, the liquid can be separated and recovered immediately after the processed product is processed, and the working time can be increased. Can be shortened. For example, the liquid is left to stand for about 15 to 20 minutes, and after the liquid is naturally allowed to flow down and separated and recovered, the opening / closing mechanism 26 of the discharge port 16 of the closed container 12 is opened to discharge the processed product. The treated product is, for example, in a state of being almost separated from the liquid in a state of having a water content of about 30%, and can be recovered in a state of being easy to handle even during transportation, management, and the like. As a result, the processed product can be processed and the processed product and the liquid can be separated and collected with only one device. In addition, it is not necessary to take out the unwieldy processed material mixed with the liquid to the outside, and the processed material can be separated and recovered directly from the closed container by a simple operation in succession to the processing. In addition, the structure of separation and recovery is simple, and it can be manufactured at low cost. Each opening / closing mechanism may be opened / closed by a manual operation, or may be opened / closed by a mechanical operation using electricity or the like.

次に、図６および図７を参照して、本発明の他の実施形態による亜臨界水処理装置について説明する。なお、この説明においては、上記図１等を参照して説明した実施の形態の亜臨界水処理装置と同じ部材、部品については、同一の符号を付してその説明を省略する。
この実施の形態による亜臨界水処理装置１０は、前記処理用の密閉容器１２が、処理物である有機系廃棄物の投入部と、処理後の処理物（液体、固体）を排出する排出部を兼ねる投入兼排出部１００を備えているとともに、処理物の投入時、および処理時には、前記投入兼排出部が上方に配置される処理物投入・処理位置と、処理済み処理物を排出するため、前記投入兼排出部が上方に配置される処理物排出位置とを取りうるように、前記横方向回転軸（前記回転軸２８と同軸）周りに１８０度回転可能に構成されている。 Next, the sub-critical water treatment apparatus according to another embodiment of the present invention will be described with reference to FIGS. 6 and 7. In this description, the same members and parts as those of the sub-critical water treatment apparatus of the embodiment described with reference to FIG. 1 and the like will be designated by the same reference numerals and the description thereof will be omitted.
In the sub-critical water treatment apparatus 10 according to this embodiment, the airtight container 12 for the treatment has an input unit for organic waste as a processed product and a discharge unit for discharging the treated product (liquid, solid) after the treatment. In addition to providing the loading / discharging unit 100 that also serves as the above, at the time of loading and processing of the processed material, the processing material charging / processing position where the charging / discharging unit is arranged above and the processed material are discharged. It is configured to be rotatable 180 degrees around the lateral rotation axis (coaxial with the rotation axis 28) so that the input / discharge unit can take a position of discharging the processed material arranged above.

そのため、本実施の形態では、前記密閉容器１２は、その両側端に、そこからそれぞれ外側に延在するほぼ円筒形の支持ハブ１２ａ、１２ｂが固定され、この支持ハブ１３ａ、１３ｂは、それぞれ支持台１１０ａ、１１０ｂに設けられたベアリング装置１１２ａ、１１２ｂにより、回転自在に支持されている。この構造によって、前記密閉容器１２は、接地面から所定の高さで回転自在に配置されている。 Therefore, in the present embodiment, the closed container 12 has substantially cylindrical support hubs 12a and 12b extending outward from the closed container 12 fixed to both side ends thereof, and the support hubs 13a and 13b are supported, respectively. It is rotatably supported by bearing devices 112a and 112b provided on the bases 110a and 110b. With this structure, the closed container 12 is rotatably arranged at a predetermined height from the ground plane.

そして、前記支持台１１０ａには、密閉容器１２を１８０度回動するための回転駆動装置１２０が設けられている。この回転駆動装置１２０は、モータ１２２と、このモータの回転駆動力を前記密閉容器１２の支持ハブ１２ａに伝達するための歯車列機構１２４を備えている。 The support base 110a is provided with a rotation drive device 120 for rotating the closed container 12 by 180 degrees. The rotary drive device 120 includes a motor 122 and a gear train mechanism 124 for transmitting the rotary drive force of the motor to the support hub 12a of the closed container 12.

以上の構成により、本実施の形態では、密閉容器１２内での原料である廃棄物の処理が完了した後、前記回転駆動装置１２０を駆動して、密閉容器を１８０度回動して、図７に示した処理物排出位置に位置付ける。
この位置では、図からも分かるように、前記投入兼排出部１００も密閉容器の回転に伴って、１８０度回動して、密閉容器１２の真下に配置され、排出部としての機能を果たす。
その結果として、前記投入兼排出部１００は、投入部としても排出部としても機能を果たし、その結果、密閉容器の原料・排出物のための開口が兼用でき、したがって、バルブの設置も一つで済むようになる。
なお、前記密閉容器１２内での原料である廃棄物の処理中に、前記前記回転駆動装置１２０を作動させて、該密閉容器を回移動させれば、内部の廃棄物が反転するので、攪拌がより良好なものとなる。 With the above configuration, in the present embodiment, after the treatment of the waste as a raw material in the closed container 12 is completed, the rotary drive device 120 is driven to rotate the closed container by 180 degrees. It is positioned at the processed product discharge position shown in 7.
At this position, as can be seen from the figure, the loading / discharging unit 100 also rotates 180 degrees with the rotation of the closed container and is arranged directly under the closed container 12 to function as a discharging unit.
As a result, the input / discharge unit 100 functions as both an input / discharge unit and, as a result, an opening for the raw material / discharge of the closed container can be shared, and therefore, one valve is installed. Will be enough.
If the rotary drive device 120 is operated to rotate the closed container during the treatment of the waste as a raw material in the closed container 12, the internal waste is inverted, so that the mixture is stirred. Will be better.
