Description

含油性物質の油分分離装置Oil separator for oil-containing substances
　本発明は、オイルサンド、オイルシェール或いはオイルスラッジなどの含油性物質から効率よく油分を分離する含油性物質の油分分離装置に関するものである。 The present invention relates to an oil content separation apparatus for an oil content material that efficiently separates the oil content from the oil content material such as oil sand, oil shale or oil sludge.
　通常原油の埋蔵量は１兆７千億バレルから２兆バレル程度と推定されており、限界がある。また、確認埋蔵量の約半分が中東に集中しており、政治情勢の影響を受けやすく、安定供給が必ずしも保証されているわけではない。それに対し、オイルサンドやオイルシェールから得られる重質原油は埋蔵量４兆バレルともいわれ、これら天然の含油性物質から安全かつ効率的に油分を抽出する技術の実現が待たれている。 通常 Normal crude oil reserves are estimated to be around 1.7 trillion to 2 trillion barrels, which is limited. In addition, about half of the confirmed reserves are concentrated in the Middle East and are easily affected by the political situation, and a stable supply is not necessarily guaranteed. On the other hand, heavy crude oil obtained from oil sands and oil shale is said to have a reserve of 4 trillion barrels, and the realization of a technology for extracting oil from these natural oil-containing substances safely and efficiently is awaited.
　さらに、石油産業から発生するオイルスラッジは、単一の廃棄物としては地球上でもっとも多量に存在しているといわれ、かつ、その量は増大する一方でほとんど処理されず、各地で野積みにされているのが実情である。しかし、焼却処理は大気汚染を招くことから、不法な埋め立てや海洋投棄が行われているという実態があり、それによる環境汚染が社会問題化している。そこで、廃棄されていた含油性物質に含まれている油分を再利用することも社会的要請となっている。 In addition, oil sludge generated from the oil industry is said to be the most abundant on the earth as a single waste. It is the actual situation. However, since incineration causes air pollution, there is the actual situation that illegal landfill and ocean dumping are performed, and environmental pollution caused by that has become a social problem. Therefore, it is a social request to reuse the oil contained in the discarded oil-containing substance.
  含油性物質に含まれている油分を再利用するためは、油分を変質させることなく含油性物質に含まれている固形分等から分離することが必要である。含油性物質に含まれている固形分等から油分を気化させて分離する際には、気化された油分が引火しやすいという危険があり、含油性物質から油分を気化させる際に油分への引火を妨げる技術の開発が要望されていた。 再 In order to reuse the oil contained in the oil-containing substance, it is necessary to separate it from the solids contained in the oil-containing substance without altering the oil. When the oil content is vaporized and separated from the solids contained in the oil-containing substance, there is a risk that the vaporized oil will easily ignite, and when the oil content is vaporized from the oil-containing substance, the oil content is ignited. There has been a demand for the development of technology that prevents this.
  また、液体状態で埋蔵されている石油の掘削と比較して、コスト的に引けを取らないようにするためには、一時に十分な量を含油性物質から分離することが必要である。そこで、処理量を増大させる技術の開発も要望されていた。 In addition, it is necessary to separate a sufficient amount from the oil-containing substance at a time so as not to be inferior in cost compared with the drilling of oil buried in a liquid state. Therefore, there has been a demand for development of a technique for increasing the processing amount.
  従来、含油性物質から油分を気化させる際に油分への引火のおそれを消失させる技術としては、例えば、特許文献１に記載のものが知られている。 2. Description of the Related Art Conventionally, for example, a technique described in Patent Document 1 is known as a technique for eliminating the risk of ignition of an oil component when the oil component is vaporized from an oil-containing substance.
  特許文献１には、含油性物質を過熱水蒸気で瞬時に分解して油分を気化させることで、引火のおそれを消失させる油分分離技術が記載されている。 Patent Document 1 describes an oil separation technique that eliminates the risk of ignition by instantly decomposing an oil-containing substance with superheated steam to vaporize the oil.
特開２０１２－０９１０９１号公報JP 2012-091091 A
  特許文献１に係る油分分離装置では、オイルスラッジに超音速で加熱水蒸気が噴射されるために、スラッジ部分が飛散して処理槽の壁面に衝突したり、噴射ノズルに衝突したりするなどして損傷を与える可能性があるという問題点がある。 In the oil separation device according to Patent Document 1, since heated steam is jetted onto the oil sludge at supersonic speed, the sludge portion scatters and collides with the wall of the treatment tank, or collides with the injection nozzle. There is a problem of possible damage.
  また、特許文献１に係る油分分離装置では、採算ベースに乗せるために十分な処理量が得られない可能性があることが判明した。 It has also been found that the oil separation device according to Patent Document 1 may not be able to obtain a sufficient processing amount to be put on the profit base.
  本発明はこのような事情に鑑みてなされたものであり、加熱水蒸気を噴射して含油性物質からの油分の分離を安全かつ効率的に行うことができ、かつ、採算ベースに乗せるために十分な処理量を得ることができる油分分離装置を提供することを目的とする。 The present invention has been made in view of such circumstances, and it is possible to safely and efficiently perform separation of oil from oil-containing substances by injecting heated steam, and is sufficient to be put on a profitable base. An object of the present invention is to provide an oil separation device capable of obtaining a large amount of treatment.
  このような目的に応えるために本発明（請求項１記載の発明）に係る含油性物質の油分分離装置は、外部から供給される含油性物質に対して過熱蒸気噴射口から超音速の過熱蒸気が噴射される噴射空間を有する処理槽を備え、前記処理槽はその本体が円筒状に構成され、前記円筒状本体はその円筒軸方向が天地方向と垂直に交差するように配置され、前記過熱蒸気噴射口が前記円筒状本体の円筒曲面内側円周方向に倣う方向を噴出方向として前記円筒状本体の天地方向底部に開口されて設けられ、前記処理槽の天地方向底部に天地方向下方から上方に向けて前記含油性物質を供給する供給口が設けられ、前記円筒状本体の一方の底面中央に前記円筒状本体の軸線を中心とする円形の含油性物質排出口が設けられている含油性物質の油分分離装置であって、前記円筒状本体の円筒曲面内壁に、前記円筒状本体の半径方向内側に向かって１又は２以上の円形板状の隔壁が円筒状本体の円形平面状底面と平行に設けられ、前記円形板状の隔壁には、前記円筒状本体の軸線を中心とする円形孔部が設けられ、前記円筒状本体の一対の底部平面内壁の間の前記隔壁により区切られてなる処理溝の各々に前記過熱蒸気噴射口と前記含油性物質を供給する供給口とが備えられていることを特徴とする。 In order to meet such an object, the oil content separation apparatus for oil-containing substances according to the present invention (the invention described in claim 1) is directed to superheated superheated steam from the superheated steam injection port for oil-containing substances supplied from the outside. A treatment tank having an injection space through which the main body is jetted, the main body of the treatment tank being configured in a cylindrical shape, the cylindrical main body being arranged so that a cylindrical axis direction thereof intersects the vertical direction vertically, and the overheating A steam injection opening is provided at the bottom in the top-bottom direction of the cylindrical body, with the direction following the inner circumferential direction of the cylindrical curved surface of the cylindrical body as an ejection direction, and the top of the processing tank from above in the top-bottom direction. An oil-impregnated material is provided with a supply port for supplying the oil-containing material toward the center, and a circular oil-containing material discharge port is provided at the center of one bottom surface of the cylindrical body with the axis of the cylindrical body as the center. Oil separation of substances In the apparatus, one or more circular plate-shaped partition walls are provided in parallel with the circular flat bottom surface of the cylindrical main body on the inner wall of the cylindrical curved surface of the cylindrical main body toward the radially inner side of the cylindrical main body. The circular plate-shaped partition wall is provided with a circular hole centering on the axis of the cylindrical body, and a processing groove formed by the partition wall between the pair of bottom planar inner walls of the cylindrical body. Each is provided with the superheated steam injection port and the supply port for supplying the oil-containing substance.
　このような構成によれば、高温高圧の過熱蒸気を超音速で、処理槽円筒状本体内の噴射空間の円筒曲面内側円周方向に沿って前記噴射空間の天地方向底部に噴射し、一方含油性物質を前記円筒状噴射空間の天地方向底部に天地方向下方から上方に向けて供給することにより、この円筒状噴射空間内において、円筒状噴射空間の円周方向に沿った方向に過熱蒸気が噴射される。この過熱蒸気が超高速で含油性物質に衝突することで、前記噴射空間で含油性物質が瞬間的に解砕されて固形物質及び気化した油分に分離される。 According to such a configuration, high-temperature and high-pressure superheated steam is injected at a supersonic speed onto the bottom in the vertical direction of the injection space along the circumferential direction of the cylindrical curved surface of the injection space in the treatment tank cylindrical body, In this cylindrical injection space, superheated steam is generated in a direction along the circumferential direction of the cylindrical injection space by supplying the active substance from the lower side to the upper side in the vertical direction. Be injected. When the superheated steam collides with the oil-containing substance at an ultra high speed, the oil-containing substance is instantaneously crushed in the jetting space and separated into a solid substance and vaporized oil.
  そうして分離された固形物質及び気化した油分は円筒状噴射空間内側において円筒曲面によって形成される円周方向に倣う方向に上方に吹き上げられ、円周方向に回動し、その過程で固形物質は自重と処理槽内の空気との摩擦により回動速度が減少することで、処理槽円筒状本体の軸線中央部を中心に処理槽円筒状本体の軸線中央部寄りを回動することになり、過熱蒸気が継続して噴射されていることで処理槽内の気圧が外部より高くなっていることから、処理槽円筒状本体の一方の底面に設けられた含油性物質排出口から排出される。一方、気化した油分は上記と混合され、処理槽内の気圧が外部より高くなっていることから、含油性物質排出口から固形物質と共に排出される。 The separated solid substance and the vaporized oil are blown upward in a direction following the circumferential direction formed by the cylindrical curved surface inside the cylindrical injection space and rotated in the circumferential direction. The rotation speed decreases due to the friction between its own weight and the air in the processing tank, and the center of the axis of the processing tank cylindrical body rotates around the center of the axis of the processing tank cylindrical body. Since the superheated steam is continuously injected, the pressure inside the treatment tank is higher than the outside, so that it is discharged from the oil-containing substance discharge port provided on one bottom surface of the treatment tank cylindrical body. . On the other hand, the vaporized oil is mixed with the above, and since the atmospheric pressure in the treatment tank is higher than the outside, it is discharged together with the solid substance from the oil-containing substance discharge port.
  ここで本発明では、処理槽円筒状本体の一方の閉じた底面ともう一方の含油性物質排出口との間に、中央に円形の孔部を備える隔壁を底面と平行に設けることにより底面と隔壁、或いは隔壁同士に挟まれた複数の処理溝各々に熱蒸気噴射口が備えられていることで、処理量を増大させることができる。 Here, in the present invention, by providing a partition with a circular hole in the center in parallel with the bottom surface between one closed bottom surface of the treatment tank cylindrical body and the other oil-containing substance discharge port, the bottom surface The amount of processing can be increased by providing the thermal vapor injection port in each of the partition walls or each of the plurality of processing grooves sandwiched between the partition walls.
  含油性物質排出口から排出された固形物質と油分混合蒸気は、含油性物質排出口に接続された遠心分離機に流し込まれ、固形物質はその重量により下方に落下し、油分混合蒸気は遠心分離機上方に設けられた気化物質排出口から排出され、冷却液化機構において、油分と水分に分離され、分離された油分が利用可能となる。 The solid substance and oil mixed vapor discharged from the oil-containing substance outlet are poured into a centrifuge connected to the oil-containing substance outlet, the solid substance falls downward due to its weight, and the oil mixture vapor is centrifuged. It is discharged from the vaporized substance discharge port provided at the upper part of the machine, and is separated into oil and moisture by the cooling liquefaction mechanism, and the separated oil becomes available.
  特許文献１に係る油分分離装置では、図１に示すように、処理槽円筒状本体において、高温の過熱蒸気が内壁に超音速で吹き付けられるため、処理槽円筒状本体は所定の強度、耐腐食性を備える必要があり、その直径があまり大きなものを製造するには、困難が伴う。さらにあまり直径が大きなものを使用すると、処理槽円筒状本体の天地方向底部で噴出された過熱蒸気と衝突した固形物質が処理槽円筒状本体の天地方向上部方向に回動している途中で角速度を失い、処理槽円筒状本体の一方の底面に設けられた含油性物質排出口から十分に排出されずに処理槽内に残留することになる。その状態の処理槽内に新たな含油性物質を供給すると、処理槽内に残留する固形物質がさらに増加することになり、固形物質に回動するために十分な角速度を与えることがさらに困難になる。また、角速度を補うために、加熱水蒸気の速度を上げれば、スラッジ部分が飛散して処理槽の壁面に衝突したり、噴射ノズルに衝突したりするなどして損傷を与える可能性がさらに大きくなる。以上の理由から、処理槽の直径を大きくすることにより処理量を増加させることは困難である。 In the oil separation device according to Patent Document 1, as shown in FIG. 1, in the treatment tank cylindrical body, high-temperature superheated steam is blown onto the inner wall at supersonic speed, so that the treatment tank cylindrical body has a predetermined strength and corrosion resistance. It is difficult to manufacture a product having a large diameter. If a material with a too large diameter is used, the solid velocity that collides with the superheated steam ejected from the bottom of the processing tank cylindrical body in the vertical direction is rotating in the middle of the processing tank cylindrical main body toward the celestial region improvement section. And remains in the treatment tank without being sufficiently discharged from the oil-containing substance discharge port provided on one bottom surface of the treatment tank cylindrical main body. If a new oil-containing substance is supplied into the treatment tank in that state, the solid substance remaining in the treatment tank will further increase, making it more difficult to give sufficient angular velocity to rotate the solid substance. Become. In addition, if the heating steam speed is increased to compensate for the angular velocity, the possibility that the sludge portion will scatter and collide with the wall surface of the treatment tank or collide with the spray nozzle is further increased. . For the above reasons, it is difficult to increase the processing amount by increasing the diameter of the processing tank.
  特許文献１に係る油分分離装置では、処理槽円筒状本体の両底面の間隔をその直径に比して１０％から２０％程度としていたが、処理槽の直径を大きくすることにより処理量を増加させることが困難であるため、処理槽円筒状本体の両底面の間隔を広げることにより処理量を増加させることを試みた。処理槽の直径を大きくせずに処理量を増加させることができれば、加熱水蒸気の噴射速度を抑えることができ、スラッジ部分が飛散して処理槽の壁面に衝突したり、噴射ノズルに衝突したりするなどして損傷を与える可能性を減少させることができるからである。 In the oil separation device according to Patent Document 1, the interval between both bottom surfaces of the cylindrical body of the processing tank is set to about 10% to 20% compared to the diameter, but the processing amount is increased by increasing the diameter of the processing tank. Since it is difficult to do so, an attempt was made to increase the processing amount by widening the distance between both bottom surfaces of the cylindrical body of the treatment tank. If the treatment amount can be increased without increasing the diameter of the treatment tank, the heating steam injection speed can be suppressed, and the sludge part can scatter and collide with the wall of the treatment tank, or collide with the injection nozzle. This is because the possibility of damaging it can be reduced.
  しかし処理槽円筒状本体の両底面の間隔を広げることでは、処理量を有意に増加させることはできなかった。 However, the treatment amount could not be increased significantly by increasing the distance between the bottom surfaces of the cylindrical body of the treatment tank.
  特許文献１に係る油分分離装置では、図２に示すように、処理槽円筒状本体の円周方向に固形物質が回動する際に、固形物質は処理槽円筒状本体の底面と側部曲面内壁とからなる隅部寄りを回動する。 In the oil separation device according to Patent Document 1, as shown in FIG. 2, when the solid material rotates in the circumferential direction of the treatment tank cylindrical body, the solid material is removed from the bottom surface and the side curved surface of the treatment tank cylindrical body. The corner near the inner wall is rotated.
  図３に示すように、処理槽円筒状本体の両底面の間隔を広げても、固形物質が処理槽円筒状本体の底面と側部曲面内壁とからなる隅部寄りを回動するために、処理槽円筒状本体の容積を増やしたことに比例するほど有意な増加量を得ることができなかった。 As shown in FIG. 3, even if the interval between both bottom surfaces of the treatment tank cylindrical body is widened, the solid substance rotates near the corner formed by the bottom surface of the treatment tank cylindrical body and the side curved inner wall. A significant increase could not be obtained in proportion to the increase in the volume of the treatment tank cylindrical body.
  そこで、本発明に係る油分分離装置では、処理槽円筒状本体内に中央に円形孔部を備える隔壁を設け、底面と隔壁或いは隔壁同士に挟まれた処理溝に過熱蒸気噴射装置と含油性物質を供給する供給口とが備えられることにより、底面と側部曲面内壁とからなる処理溝の隅部だけでなく、隔壁面と側部曲面内壁とからなる処理溝の隅部を固形物質が回動するので、供給量を増やした分の含油性物質が固形物質と気化した油分に分離される。 Therefore, in the oil separation device according to the present invention, a partition wall having a circular hole is provided in the center in the cylindrical main body of the processing tank, and the superheated steam injection device and the oil-containing substance are disposed in the processing groove sandwiched between the bottom surface and the partition wall or between the partition walls. The supply port for supplying the solid material allows not only the corner of the processing groove formed by the bottom surface and the side curved inner wall but also the corner of the processing groove formed by the partition wall surface and the side curved inner wall to rotate. Therefore, the oil-containing substance corresponding to the increased supply amount is separated into the solid substance and the vaporized oil.
  本発明（請求項１記載の発明）に係る含油性物質の油分分離装置は、請求項１に記載の含油性物質の油分分離装置であって、前記円筒状本体の直径が１０００ｍｍ以上１５００ｍｍ以下であり、前記処理槽の幅が１００ｍｍ以上３００ｍｍ以下であり、前記円形板状の隔壁の前記円筒状本体の円筒曲面内壁との接合部から前記円形板状の隔壁に設けられた円形孔部の縁までの高さが５０ｍｍ以上３００ｍｍ以下であることを特徴とする。 An oil-separating device for oil-containing substances according to the present invention (the invention described in claim 1) is the oil-separating device for oil-containing substances according to claim 1, wherein the cylindrical main body has a diameter of 1000 mm to 1500 mm. A width of the processing tank is 100 mm or more and 300 mm or less, and an edge of a circular hole provided in the circular plate-shaped partition wall from a joint portion between the circular plate-shaped partition wall and a cylindrical curved inner wall of the cylindrical main body The height is up to 50 mm to 300 mm.
  このように構成することで、処理槽円筒状本体の直径の製造にさほど困難がなく、処理槽円筒状本体の天地方向底部で噴出された過熱蒸気と衝突した固形物質が処理槽円筒状本体の天地方向上部方向に回動している途中で角速度を失い、処理槽円筒状本体の一方の底面に設けられた含油性物質排出口から十分に排出されずに処理槽内に残留すること、及び、処理溝の幅が広すぎるときに処理溝の隅部を固形物質が回動することにより噴射空間の容積を増やしても処理量が有意に増加しないという問題とを防止することができ、処理槽円筒状本体の軸線中央部を中心に処理槽円筒状本体の軸線中央部寄りを回動する固形物質が隔壁に妨げられずに排出口から排出される。 By comprising in this way, there is not so much difficulty in manufacture of the diameter of a processing tank cylindrical main body, and the solid substance which collided with the superheated steam spouted at the top-bottom direction bottom part of a processing tank cylindrical main body of a processing tank cylindrical main body The angular velocity is lost while rotating in the direction of the Tenchi region improvement part, and it remains in the treatment tank without being sufficiently discharged from the oil-containing substance discharge port provided on one bottom surface of the treatment tank cylindrical body, and When the width of the processing groove is too wide, the solid material rotates around the corner of the processing groove, thereby preventing the problem that the processing amount does not increase significantly even if the volume of the injection space is increased. A solid substance that rotates around the center of the axis of the cylindrical body of the tank turns around the center of the axis of the cylindrical body of the processing tank and is discharged from the discharge port without being blocked by the partition wall.
　以上説明したように本発明に係る油分分離装置によれば、加熱水蒸気を噴射して含油性物質からの油分の分離を安全かつ効率的に行うことができ、かつ、採算ベースに乗せるために十分な処理量を得ることができる油分分離装置を得ることができる。 As described above, according to the oil separation device according to the present invention, it is possible to safely and efficiently separate the oil from the oil-containing substance by injecting heated steam, and is sufficient for placing on the profit base. An oil separation device that can obtain a large amount of treatment can be obtained.

　図４乃至図５は本発明に係る含油性物質の油分分離装置の実施例を示す。

In these drawings, what is indicated by reference numeral 1 as a whole is an oil component separation apparatus for oil-containing substances that characterizes the present invention.
  図４は本発明の含油性物質の油分分離装置１の処理槽円筒状本体を平面状底面の方向から見た模式図である。
　図４において、符号１０は、本発明に係る含油性物質の油分分離装置の処理槽円筒状本体であり、その円筒軸方向が天地方向と垂直に交差するように配置され、過熱蒸気噴射装置３０が円筒状本体１０の天地方向底部１０ａにおいて円筒状本体１０の円筒軸方向と直角の方向で天地方向と垂直に交差するように接続され、過熱蒸気噴射口３１が処理槽円筒状本体１０の円筒曲面内側円周方向に倣う方向を噴出方向として前記円筒状本体１０の天地方向底部１０ａに開口されて設けられている。 FIG. 4 is a schematic view of the cylindrical body of the treatment tank of the oil-containing substance oil separator 1 according to the present invention as viewed from the plane bottom.
In FIG. 4, reference numeral 10 denotes a treatment tank cylindrical main body of the oil content separation apparatus for oil-containing substances according to the present invention, which is arranged such that the cylindrical axis direction intersects the vertical direction vertically, and the superheated steam injection device 30. Are connected so as to intersect the vertical direction perpendicular to the cylindrical axis direction of the cylindrical main body 10 at the vertical bottom 10a of the cylindrical main body 10, and the superheated steam injection port 31 is the cylinder of the processing tank cylindrical main body 10. A direction following the inner circumferential direction of the curved surface is provided as an opening in the bottom 10a in the vertical direction of the cylindrical main body 10 with an ejection direction.
　前記処理槽円筒状本体１０の天地方向底部１０ａに天地方向下方から上方に向けて前記含油性物質を供給する含油性物質供給口２１が設けられ、前記含油性物質はスクリューコンベア２０により天地方向下方から上方に向けて供給される。 An oil-containing substance supply port 21 for supplying the oil-containing substance from below to above is provided at the bottom 10a in the top-bottom direction of the cylindrical body 10 of the treatment tank. From above.
この含油性物質供給口２１を介して外部より供給される含油性物質に対して過熱蒸気噴射口３１から超音速の過熱蒸気を噴射する。過熱蒸気を超音速流として、供給されている含油性物質に対して強制衝突させることによって処理槽円筒状本体１０に供給された含油性物質を解砕、撹拌しつつ油分を気化させ、固形物質と分離する。　 Supersonic superheated steam is injected from the superheated steam injection port 31 to the oily material supplied from the outside through the oil-containing material supply port 21. The superheated steam is forced to collide against the supplied oil-containing substance as a supersonic flow to crush the oil-containing substance supplied to the treatment tank cylindrical main body 10, vaporize the oil while stirring, and solid matter And separate. *
  そうして分離された固形物質及び気化した油分は円筒状噴射空間１１において円筒曲面によって形成される円周方向に倣う方向に天地方向上部１０ａに向けて吹き上げられ、円周方向に回動する。噴射空間１１内を回動する固形物質は自重と処理槽内の空気との摩擦により回動速度が減少することで、噴射空間１１内の矢印に示されるように処理槽円筒状本体１０の軸線中央部を中心に処理槽円筒状本体１０の軸線中央部寄りを回動することになり、過熱蒸気が継続して噴射されていることで噴射空間１１内の気圧が外部より高くなっていることから、処理槽円筒状本体１０の一方の底面に設けられた含油性物質排出口１７から排出される。一方、気化した油分は前記過熱蒸気と混合され、噴射空間１１内の気圧が外部より高くなっていることから、含油性物質排出口１７から固形物質と共に排出される。 The solid substance and the vaporized oil component thus separated are blown up toward the celestial region improvement unit 10a in a direction following the circumferential direction formed by the cylindrical curved surface in the cylindrical injection space 11, and rotate in the circumferential direction. The solid material that rotates in the injection space 11 is reduced in rotation speed due to friction between its own weight and the air in the processing tank, so that the axis of the cylindrical body 10 of the processing tank as indicated by the arrow in the injection space 11. The central portion of the treatment tank cylindrical body 10 is rotated around the center of the axis, and the superheated steam is continuously injected, so that the atmospheric pressure in the injection space 11 is higher than the outside. Are discharged from an oil-containing substance discharge port 17 provided on one bottom surface of the treatment tank cylindrical main body 10.

　サイクロン分離機４０において遠心分離、衝突分離等により過熱蒸気と混合された気化した油分と固形物質５１との分離が行われる。分離された過熱蒸気と混合された気化した油分はサイクロン離機４０上方の気化物質排出口４１から排出され、冷却液化機構において、油分と水分に分離され、分離された油分が利用可能となる。この際、気化物質排出口４１にはバグフィルタ等を備え、サイクロンで捕集しきれなかった超微粉を捕集することが望ましい。一方、固形物質５１はサイクロン離機４０下方の固形物質排出口から残渣タンク４３へ排出される。 In the cyclone separator 40, the vaporized oil and the solid substance 51 mixed with superheated steam are separated by centrifugal separation, collision separation, or the like. The vaporized oil mixed with the separated superheated steam is discharged from the vaporized substance discharge port 41 above the cyclone releaser 40, and is separated into oil and moisture by the cooling liquefaction mechanism, and the separated oil can be used. At this time, it is desirable that the vaporized substance discharge port 41 is provided with a bag filter or the like to collect ultra fine powder that could not be collected by the cyclone.
