Description

この発明は、水流式浮遊物回収装置、特に海、湖沼、河川などで回収場所に浮かべ、油などの浮遊物を回収する水流式浮遊物回収装置に関する。 The present invention relates to a water flow type floating material collection device, and more particularly to a water flow type floating material collection device that collects floating material such as oil floating in a collection place in the sea, lakes, rivers and the like.

水流式浮遊物回収装置として、水面に浮かぶ油などの汚染物層を除去する装置が知られている（以下の説明では、汚染物が油であるとする）。この油回収装置は、導水路とこれに接続されたサイクロン室を備えており、サイクロン室には円筒状外壁に入口が設けられている。油回収装置は、船に搭載される。水と油とは、油回収装置と水との相対速度を利用して導水路に取り入れられ、導水路から上記入口を経てサイクロン室に外壁接線方向に沿って流れ込む。水から完全に分離した油はサイクロン室の上部の排出口から取り出され、油が取り除かれた水はサイクロン室下部の出口から水中に排出される。   An apparatus that removes a contaminant layer such as oil floating on the water surface is known as a water-flow floating substance recovery apparatus (in the following description, the contaminant is assumed to be oil). This oil recovery apparatus includes a water conduit and a cyclone chamber connected thereto, and the cyclone chamber is provided with an inlet on a cylindrical outer wall. The oil recovery device is mounted on the ship. Water and oil are introduced into the water conduit using the relative speed between the oil recovery device and water, and flow from the water conduit into the cyclone chamber along the tangential direction of the outer wall through the inlet. The oil completely separated from the water is taken out from the discharge port at the top of the cyclone chamber, and the water from which the oil has been removed is discharged into the water from the outlet at the bottom of the cyclone chamber.

従来の水流式浮遊物回収装置では、波がある場合に油回収作業船の前進により導水路内に侵入した水は波エネルギを伴っており、導水路内で波動現象を生じる。波はサイクロン室の外壁に突き当たって反射され、浮遊物が導水路の流入口から流出する。このために、浮遊物の回収効率が低下していた。   In the conventional water-flow floating substance recovery device, when there is a wave, the water that has entered the water conduit by the advance of the oil recovery work ship is accompanied by wave energy, and a wave phenomenon occurs in the water conduit. The wave hits the outer wall of the cyclone chamber and is reflected, and the suspended matter flows out from the inlet of the conduit. For this reason, the collection | recovery efficiency of the floating material fell.

この発明は、波がある場合であっても効率よく浮遊物を回収することができる水流式浮遊物回収装置を提供することを課題としている。   This invention makes it a subject to provide the water-flow type floating substance collection | recovery apparatus which can collect | recover a floating substance efficiently even when there exists a wave.

この発明の水流式浮遊物回収装置は、図１および図２に示すようにサイクロン室１０と、サイクロン室１０に浮遊物を含む水を導く導水路３０とを備えており、サイクロン室１０内に浮上した浮遊物を吸引して、サイクロン室１０外に排出する。導水路流入口３１を横切る固定堰５１が、前記サイクロン室流入口３１に設けられている。   As shown in FIGS. 1 and 2, the water flow type floating substance recovery apparatus of the present invention includes a cyclone chamber 10 and a water conduit 30 that guides water containing floating substances to the cyclone chamber 10. The floated floating material is sucked and discharged out of the cyclone chamber 10. A fixed weir 51 that crosses the water conduit inlet 31 is provided in the cyclone chamber inlet 31.

この発明の水流式浮遊物回収装置１では、サイクロン室流入口３１に設けられた導水路流入口３１を横切る固定堰５１が、導水路３０内に侵入する波エネルギを抑えるとともに、導水路３０内で生じた反射流を小さくする。この結果、導水路３０内に流入した浮遊物が逆流して導水路３０から流出しないので、浮遊物回収効率が高くなる。   In the water flow type floating material recovery apparatus 1 according to the present invention, the fixed weir 51 that crosses the water conduit inlet 31 provided in the cyclone chamber inlet 31 suppresses wave energy that enters the water conduit 30, and the inside of the water conduit 30. To reduce the reflected flow generated in As a result, the floating matter flowing into the water conduit 30 flows backward and does not flow out of the water conduit 30, so that the floating matter recovery efficiency is increased.

上記水流式浮遊物回収装置において、固定堰５１の直後に配置したフロート５５と、フロート５５に固定され、導水路３１を横切りかつ静水状態での堰頂の位置が固定堰５１のものより高い昇降堰５３とを設けることが好ましい。喫水、油回収作業船の傾斜などの変動により導水路３０に対する水位が変化し、固定堰５１の水面ＷＬに対する堰頂高さ位置が変化してもフロート５５が上下し、昇降堰５３が昇降して所定の堰頂高さを自動的に維持する。これにより、喫水などが変動しても浮遊物を導水路３０内に流入させることができ、浮遊物回収効率が向上する。   In the above-mentioned water flow type floating substance recovery device, the float 55 arranged immediately after the fixed weir 51 and the lift 55 is fixed to the float 55 and crosses the water conduit 31 and the position of the top of the weir in the still water state is higher than that of the fixed weir 51 A weir 53 is preferably provided. Even if the water level with respect to the water guide channel 30 changes due to fluctuations in draft, oil recovery work boat inclination, etc., even if the height of the top of the fixed weir 51 relative to the water surface WL changes, the float 55 moves up and down, and the lifting weir 53 moves up and down To automatically maintain a predetermined weir crest height. Thereby, even if drafts etc. fluctuate, a floating thing can be made to flow in into water guide way 30, and a floating thing recovery efficiency improves.

水面ＷＬに対し導水路の流入口に向かって傾斜する多孔板からな制波板を導水路３０の後端寄り、かつ水面ＷＬ近くに設けるようにしてもよい。制波板はサイクロン室１０に向かって導水路３０内を進行する波のエネルギを吸収し、また波の反射により浮遊物が導水路流入口３１から流出するのを防ぐ。   A wave control plate made of a perforated plate that is inclined with respect to the water surface WL toward the inlet of the water conduit may be provided near the rear end of the water conduit 30 and near the water surface WL. The baffle plate absorbs the energy of waves traveling in the water conduit 30 toward the cyclone chamber 10, and prevents floating substances from flowing out of the water conduit inlet 31 due to the reflection of the waves.

導水路３０の底部４０を網目板で構成するようにしてもよい。網目板は、下方からの波エネルギの侵入を遮断するとともに、導水路３０内で生じた渦流の中心部が下方に流出するのに伴って上層部に蓄積した油粒が流出するのを防止する。   You may make it comprise the bottom part 40 of the water conduit 30 with a mesh board. The mesh plate blocks the invasion of wave energy from below and prevents the oil particles accumulated in the upper layer from flowing out as the central part of the vortex generated in the water conduit 30 flows downward. .

前記サイクロン室１０の周壁と導水路３０の側壁との間の排水路に逆止め弁を設けてもよい。導水路３０内の水位が高くなると、油水が逆流して導水路流入口３１から流出する。水位が高まると逆止め弁が開き、導水路底部４０の水は後方に排出されるので、水位が下がって油水の流出が防がれる。   A check valve may be provided in the drainage channel between the peripheral wall of the cyclone chamber 10 and the side wall of the water conduit 30. When the water level in the water conduit 30 becomes high, the oil water flows backward and flows out from the water conduit inlet 31. When the water level rises, the check valve opens and the water at the water guide channel bottom 40 is discharged rearward, so that the water level falls and the outflow of oil water is prevented.

また、前記水流式浮遊物回収装置において、サイクロン室流入口１３を指向するノズルと、ノズルに加圧水を供給する加圧水供給装置とを設け、サイクロン室流入口１３にジェット水を噴射するようにしてもよい。   Further, in the water flow type floating substance recovery apparatus, a nozzle directed to the cyclone chamber inlet 13 and a pressurized water supply device for supplying pressurized water to the nozzle are provided, and jet water is injected into the cyclone chamber inlet 13. Good.

前記サイクロン室底部に設けられた排水ダクトと、排水ダクトを指向するノズルと、ノズルに加圧水を供給する加圧水供給装置とを備え、排水ダクトにジェット水を噴射するようにしてもよい。ジェット水の噴射により、サイクロン室流入口１３の油水にサイクロン室１０内への吸込み力が生じ、排水ダクトからサイクロン室１０内への逆流を防ぐことができる。   A drainage duct provided at the bottom of the cyclone chamber, a nozzle directed to the drainage duct, and a pressurized water supply device that supplies pressurized water to the nozzle may be provided, and jet water may be injected into the drainage duct. By jetting jet water, a suction force into the cyclone chamber 10 is generated in the oil water at the cyclone chamber inlet 13, and backflow from the drain duct into the cyclone chamber 10 can be prevented.

この発明の水流式浮遊物は、導水路流入口を横切る固定堰がサイクロン室流入口に設けられているので、固定堰が導水路内に進入する波のエネルギを抑えるとともに、導水路内で生じた反射流を小さくする。この結果、導水路内に流入した浮遊物が導水路から流出しないので、浮遊物回収効率が高くなる。   In the water flow type floating material of the present invention, since the fixed weir crossing the water channel inlet is provided in the cyclone chamber inlet, the energy of the wave that the fixed weir enters the water channel is suppressed, and the water is generated in the water channel. Reduce the reflected flow. As a result, the floating matter flowing into the water conduit does not flow out of the water conduit, so the floating matter recovery efficiency is increased.

図３〜５はこの発明の実施の１形態を示すのもで、油回収装置２の概略図である。図３は上記油回収装置２の断面側面図であり、図４は正面図であり、図５は断面平面図である。以下、浮遊物が油である場合を例として説明する。   3 to 5 show an embodiment of the present invention and are schematic views of the oil recovery apparatus 2. FIG. 3 is a cross-sectional side view of the oil recovery device 2, FIG. 4 is a front view, and FIG. 5 is a cross-sectional plan view. Hereinafter, a case where the suspended matter is oil will be described as an example.

油回収装置２は主としてサイクロン室１０、導水路３０、油水流入堰５０、強制排水装置６０および油排出装置７０から構成されている。   The oil recovery device 2 mainly includes a cyclone chamber 10, a water conduit 30, an oil / water inflow weir 50, a forced drainage device 60, and an oil discharge device 70.

サイクロン室１０は、円筒状上部室１１、円錐状下部室１５および油回収室１８とからなっている。上部室１１の下端寄り流入口１３が設けられている。サイクロン室１０の内部は凹凸を少なくし、局部渦流の発生を極力少なくしている。サイクロン室１０の上部は、仕切り板１９で仕切られて油回収室１８となっている。上部室１１と油回収室１８とは、短管２０を介して通じている。油回収室１８には、これの頂部に取り付けられた空気抜き管２２を介して船上の真空ポンプ２４が接続されている。   The cyclone chamber 10 includes a cylindrical upper chamber 11, a conical lower chamber 15, and an oil recovery chamber 18. An inlet 13 near the lower end of the upper chamber 11 is provided. The inside of the cyclone chamber 10 has less unevenness, and the generation of local vortices is minimized. The upper part of the cyclone chamber 10 is partitioned by a partition plate 19 to become an oil recovery chamber 18. The upper chamber 11 and the oil recovery chamber 18 communicate with each other through a short pipe 20. A vacuum pump 24 on the ship is connected to the oil recovery chamber 18 via an air vent tube 22 attached to the top of the oil recovery chamber 18.

導水路３０は、先端部が導水路流入口３１となっており、後端はサイクロン室流入口１３に通じるようにしてサイクロン室１０に接続されている。導水路流入口３１には金網がはられており、水に浮かぶごみを捕集し、導水路内へのごみの侵入を防ぐ。導水路３０の左側壁３２の後端部はサイクロン室周壁１２と間隔をおいて周壁１２に取り付つけられており、右側壁３３の後端部はサイクロン室１０の周壁１２に接するようにして周壁１２に固定されている。導水路流入口３１寄りの部分の左側壁３２は、外に向かって開くように傾斜している。左側壁３２の傾斜により、導水路３０内の油水はサイクロン室流入口１３に向かうように流れる。サイクロン室周壁１２と左側壁３２との間は、導水路３０内に流入した油水が後方に流出しないように後壁３５で閉ざされている。   The leading end of the water conduit 30 is a water conduit inlet 31, and the rear end is connected to the cyclone chamber 10 so as to communicate with the cyclone chamber inlet 13. A wire net is attached to the waterway inlet 31 to collect dust floating on the water and prevent the entry of dust into the waterway. The rear end portion of the left side wall 32 of the water conduit 30 is attached to the peripheral wall 12 at a distance from the cyclone chamber peripheral wall 12, and the rear end portion of the right side wall 33 is in contact with the peripheral wall 12 of the cyclone chamber 10. It is fixed to the peripheral wall 12. The left side wall 32 of the portion near the water conduit inlet 31 is inclined so as to open outward. Due to the inclination of the left side wall 32, the oil in the water conduit 30 flows toward the cyclone chamber inlet 13. The cyclone chamber peripheral wall 12 and the left side wall 32 are closed by a rear wall 35 so that the oil that has flowed into the water conduit 30 does not flow backward.

逆止め弁３７が後壁３５に、サイクロン室流入口１３より低い位置に設けられている。固定堰５１が導水路流入口３１にあるために、導水路３０内に流入した油水の水位ＷＬが上昇する。また、導水路３０の底部４０が水流抵抗の大きいエキスパンドメタルで構成されているので、波が導水路３０内に打ち込んだときにも水位が高まる。水位が高くなると、油水が逆流して導水路流入口３１から流出する。逆止め弁３７は水位が高まると開き、導水路底部４０の水は後方に排出される。この結果、水位は下がり、油水の流出が防がれる。水位が下がると逆止め弁３７は閉じ、後方から導水路３０内に侵入する水は阻止される。   A check valve 37 is provided on the rear wall 35 at a position lower than the cyclone chamber inlet 13. Since the fixed weir 51 is in the water conduit inlet 31, the level WL of the oil water that has flowed into the water conduit 30 rises. Moreover, since the bottom 40 of the water conduit 30 is made of expanded metal having a large water flow resistance, the water level is increased even when a wave is driven into the water conduit 30. When the water level rises, the oil water flows backward and flows out from the water conduit inlet 31. The check valve 37 opens when the water level rises, and the water at the water guide channel bottom 40 is discharged rearward. As a result, the water level is lowered and oil water is prevented from flowing out. When the water level drops, the check valve 37 closes, and water that enters the water conduit 30 from behind is blocked.

導水路底部４０は、エキスパンドメタル（網目板）で構成されている。エキスパンドメタルは、下方からの波エネルギの侵入を遮断するとともに、導水路３０内で生じた渦流の中心部が下方に流出することに伴って上層部に蓄積いた油粒が流出するのを防止する。なお、導水路底部４０を網目なし板のめくら板にすると、サイクロン室１０への流入抵抗が大きいために油水の流入が困難となり、流入した油が逆流して導水路３０から流出する。一方、導水路底部４０を底板なしの素通しにすると、油水の流入はよくなるが、導水路３０内に生じた渦流の中心が下方へ流出するときに、上方の油粒がこれに巻き込まれて導水路底部４０より流出する。エキスパンドメタルの網目は、渦流の下方への流れを途中で断ち切り、油粒の流出を防ぐ。   The water conduit bottom 40 is made of expanded metal (mesh plate). The expanded metal blocks the invasion of wave energy from below and prevents the oil particles accumulated in the upper layer from flowing out as the central part of the vortex generated in the water conduit 30 flows out downward. . If the water guide channel bottom portion 40 is made of a meshless plate, the inflow resistance to the cyclone chamber 10 is large, making it difficult for the oil water to flow in. The oil that has flowed back flows back out of the water guide channel 30. On the other hand, if the water channel bottom 40 is passed through without a bottom plate, the inflow of oil is improved. However, when the center of the vortex generated in the water channel 30 flows downward, the upper oil particles are caught in the water and guided. It flows out from the channel bottom 40. The expanded metal mesh cuts off the downward flow of the vortex and prevents oil particles from flowing out.

多数の小孔４３が設けられた２枚の制波板４２が、上下に間隔をおいてサイクロン室周壁１２に取り付けられている。制波板４２は水面近くに配置されており、導水路流入口３１に向かって傾斜している。制波板４２は波のエネルギを吸収し、波の逆流を防ぐとともに波の打込みによる導水路３０内の水流の撹乱を少なくし、油水分離を促進する。   Two damping plates 42 provided with a large number of small holes 43 are attached to the cyclone chamber peripheral wall 12 with a space therebetween in the vertical direction. The wave control plate 42 is disposed near the water surface and is inclined toward the water conduit inlet 31. The wave control plate 42 absorbs the energy of the wave, prevents the reverse flow of the wave, reduces disturbance of the water flow in the water conduit 30 due to the wave driving, and promotes the oil-water separation.

油水流入堰５０は、固定堰５１および昇降堰５３とからなっている。固定堰５１はサイクロン室流入口１３とほぼ同じ高さの位置にあって、導水路流入口３１を横切るようにして左、右側壁３２、３３に固定されている。昇降堰５３は、フロート５５に取りつけられている。フロート５５は、サイドフロート５６と底部フロート５７とからなっている。サイドフロート５６は左フロートおよび右フロートに分かれており、底部フロート５７により連結されて一体となっている。左フロートおよび右フロートは、それぞれ左側壁３２および右側壁３３に設けられたガイド４５に沿って昇降する。昇降堰５３は固定堰５１の直後にあって、導水路流入口３１を横切るようにして底部フロート５７にボルトで取り付けられている。昇降堰５３は上下位置が調整可能となっており、堰頂５４が静水状態で固定堰５１の堰頂５２より少し高くなるように調整されている。   The oil / water inflow weir 50 includes a fixed weir 51 and a lift weir 53. The fixed weir 51 is located at substantially the same height as the cyclone chamber inlet 13 and is fixed to the left and right side walls 32 and 33 so as to cross the water conduit inlet 31. The elevating weir 53 is attached to the float 55. The float 55 includes a side float 56 and a bottom float 57. The side float 56 is divided into a left float and a right float, which are connected by a bottom float 57 and integrated. The left float and the right float move up and down along guides 45 provided on the left side wall 32 and the right side wall 33, respectively. The elevating weir 53 is immediately after the fixed weir 51 and is attached to the bottom float 57 with bolts so as to cross the water conduit inlet 31. The up-and-down weir 53 can be adjusted in the vertical position, and the dam top 54 is adjusted to be slightly higher than the dam top 52 of the fixed weir 51 in a still water state.

強制排水装置６０は、下部室１５の底部に排水ダクト６１が設けられている。水を噴射するジェットノズル６３が、排水ダクト６１内に向かって配置されている。ジェットノズル６３には船上に設置された加圧水ポンプ６６が接続されている。加圧水ポンプ６６は船外の水を汲み上げて、ジェットノズル６３に加圧水管６４を介して加圧水を供給する。固定堰５１は導入路３０内に流入する油水流の抵抗となるので、油水のサイクロン室１０内への押込み力が弱まる。このために、流入量が後述の吸油ポンプ７４の吸込み量を下回ると、排水ダクト６１からも水が吸引されてサイクロン室１０内に逆流し、油回収効率（回収油分濃度）が低下する。この強制排水装置６０は、ジェットノズル６３からジェット水を噴射し、排水ダクト６１の入口周辺の、油が分離された水を誘引してサイクロン室１０外に強制的に排水する。この強制排水により、サイクロン室流入口１３の油水はサイクロン室１０内に吸い込まれる。ジェット水の圧力および流量、ならびに排水ダクトの口径および位置は、押込み力がない場合でも上記逆流が生じない値に設定する。   The forced drainage device 60 is provided with a drainage duct 61 at the bottom of the lower chamber 15. A jet nozzle 63 for injecting water is arranged toward the drain duct 61. A pressurized water pump 66 installed on the ship is connected to the jet nozzle 63. The pressurized water pump 66 pumps outboard water and supplies pressurized water to the jet nozzle 63 via the pressurized water pipe 64. Since the fixed weir 51 provides resistance to the oil / water flow flowing into the introduction passage 30, the pushing force of the oil / water into the cyclone chamber 10 is weakened. For this reason, when the inflow amount falls below the suction amount of the oil pump 74 described later, water is also sucked from the drainage duct 61 and flows back into the cyclone chamber 10, and the oil recovery efficiency (recovered oil concentration) decreases. The forced drainage device 60 jets jet water from the jet nozzle 63, attracts water from which oil has been separated around the entrance of the drainage duct 61, and forcibly drains it outside the cyclone chamber 10. By this forced drainage, the oil water at the cyclone chamber inlet 13 is sucked into the cyclone chamber 10. The pressure and flow rate of the jet water and the diameter and position of the drainage duct are set to values that do not cause the above-described reverse flow even when there is no pushing force.

油排出装置７０は、油回収室１８に油移送管７２が接続されており、油移送管７２は船上に設置された吸油ポンプ７４を介して回収油タンク７６に接続されている。   In the oil discharge device 70, an oil transfer pipe 72 is connected to the oil recovery chamber 18, and the oil transfer pipe 72 is connected to a recovered oil tank 76 via an oil absorption pump 74 installed on the ship.

図５に示すように、導水路３０の左側壁３２から延びるアーム８１の先端にＬ形のガイドスライダ８２が設けられている。ガイドスライダ８２は、油回収作業船５の舷側に沿って鉛直方向に延びるガイド８４にはめ合っている。油回収装置２は、船上のクレーン（図示しない）でガイド８４に案内されて吊り下ろされ、または吊り上げられて油回収作業船５の舷側に取り付けられる。導水流路３０の両側壁３２、３３に掛け渡された桁８６に設けられた滑車８７は、油回収装置２を吊り下ろし、あるいは吊り上げる際に用いる。   As shown in FIG. 5, an L-shaped guide slider 82 is provided at the tip of an arm 81 extending from the left side wall 32 of the water conduit 30. The guide slider 82 is fitted to a guide 84 that extends in the vertical direction along the side of the oil recovery work boat 5. The oil recovery apparatus 2 is guided by a guide 84 by a crane (not shown) on the ship and suspended or lifted and attached to the side of the oil recovery work ship 5. A pulley 87 provided on a girder 86 spanned on both side walls 32 and 33 of the water guide channel 30 is used when the oil recovery device 2 is suspended or lifted.

上記のように構成された油回収装置２の運転および作動について、図３〜図５を参照して説明する。油回収装置２は、油が浮遊する油回収場所で油回収作業船５から水面に下ろされる。水面と固定堰５１の堰頂５２との間を油水が流入する高さに、油回収装置２は下ろされる。昇降堰５３の底部フロート５７への取付け位置は、油回収作業船５の喫水変化に応じてあらかじめ調整しておく。   The operation and operation of the oil recovery apparatus 2 configured as described above will be described with reference to FIGS. The oil recovery device 2 is lowered from the oil recovery work ship 5 to the water surface at an oil recovery place where the oil floats. The oil recovery apparatus 2 is lowered to a height at which oil water flows between the water surface and the top of the fixed weir 51. The mounting position of the elevating weir 53 on the bottom float 57 is adjusted in advance according to the draft change of the oil recovery work boat 5.

油回収作業船５の前進に伴い導水路３０に流入した油水は、サイクロン室１０の周壁１２に対しほぼ接線方向に流入口１３からサイクロン室１０内に流入する。このとき、固定堰５１は導水路３０内に進入する波のエネルギを抑えるとともに、導水路３０内で生じた反射流を小さくして流入した油が導水路３０から流出しないようにする。油水の流入が始まると、真空ポンプ２４および加圧水ポンプ６６を駆動する。加圧水ポンプ６６の駆動によりジェットノズル６３から水が排水ダクト６１に向けて噴射される。油水の接線方向の流入およびジェット水の噴射により、油水はサイクロン室１０内で渦運動を生じ、油は水から分離して渦の中心部に集まるとともに浮上する。真空ポンプ２４の駆動により油回収室１８は負圧となり、上部室１１内に浮上した油が油回収室１８内に吸い込まれる。油回収室１８に油が溜まり始めると、吸油ポンプ７４を駆動して、油を船上の油タンク７６に回収する。   The oil water that has flowed into the water conduit 30 as the oil recovery work boat 5 moves forward flows into the cyclone chamber 10 from the inlet 13 in a tangential direction with respect to the peripheral wall 12 of the cyclone chamber 10. At this time, the fixed weir 51 suppresses the energy of waves entering the water conduit 30 and reduces the reflected flow generated in the water conduit 30 so that the oil that flows in does not flow out of the water conduit 30. When the inflow of oil / water begins, the vacuum pump 24 and the pressurized water pump 66 are driven. By driving the pressurized water pump 66, water is jetted from the jet nozzle 63 toward the drainage duct 61. Due to the tangential inflow of the oil water and the jet water jet, the oil water causes a vortex motion in the cyclone chamber 10, and the oil separates from the water and collects at the center of the vortex and rises. By driving the vacuum pump 24, the oil recovery chamber 18 has a negative pressure, and the oil floating in the upper chamber 11 is sucked into the oil recovery chamber 18. When oil begins to accumulate in the oil recovery chamber 18, the oil absorption pump 74 is driven to recover the oil to the oil tank 76 on the ship.

喫水、油回収作業船５の傾斜などの変動により導水路３０に対する水位が変化すると、固定堰５１の水面ＷＬに対する堰頂高さ位置が変化する。このため、固定堰５１を超える水量が微妙に変動するので、昇降堰５３により堰頂高さ位置を自動的に調整する。例えば、水面ＷＬが導水路３０に対し上昇するとフロート５５が上昇し、昇降堰５３が固定堰５１に代わって所定の堰頂高さを自動的に維持する。   When the water level with respect to the water guide channel 30 changes due to fluctuations in draft and the inclination of the oil recovery work boat 5, the height of the top of the fixed weir 51 relative to the water surface WL changes. For this reason, since the amount of water exceeding the fixed weir 51 slightly fluctuates, the height of the weir top is automatically adjusted by the elevating weir 53. For example, when the water surface WL rises with respect to the water conduit 30, the float 55 rises, and the elevating weir 53 automatically maintains a predetermined weir top height instead of the fixed weir 51.

図６は、この発明の他の実施の形態である油回収装置３を示している。固定堰５１および昇降堰５３を設けたことにより、油水がサイクロン室流入口１３に流入し難くなり、サイクロン室流入口１３の手前に油が堆積しやすくなる。油の粘度が高い場合、特に堆積しやすい。この実施の形態では、油回収装置３に油水押込み装置９０を設けて油の堆積を防ぐようにしている。油水押込み装置９０は、サイクロン室流入口１３に向かって水を噴射するジェットノズル９２を備えている。ジェットノズル９２には、船上に設置された加圧水ポンプ９６が接続されている。加圧水ポンプ９６は船外の水を汲み上げて、ジェットノズル９２に加圧水管９４を介して加圧水が供給する。   FIG. 6 shows an oil recovery apparatus 3 according to another embodiment of the present invention. Providing the fixed weir 51 and the elevating weir 53 makes it difficult for oil water to flow into the cyclone chamber inlet 13, and the oil tends to accumulate in front of the cyclone chamber inlet 13. It is particularly easy to deposit when the viscosity of the oil is high. In this embodiment, the oil recovery device 3 is provided with an oil water pushing device 90 to prevent oil accumulation. The oil-water pushing device 90 includes a jet nozzle 92 that jets water toward the cyclone chamber inlet 13. A pressurized water pump 96 installed on the ship is connected to the jet nozzle 92. The pressurized water pump 96 pumps outboard water and supplies the pressurized water to the jet nozzle 92 via the pressurized water pipe 94.

ジェット水をサイクロン室流入口１３に向けて噴射することにより、流入口１３手前の油水はサイクロン室１０内に押し込まれ、サイクロン室流入口１３付近に堆積した油は水流に押し込まれ、あるいは誘引されて導水路３０からサイクロン室１０へ流れ込む。なお、油が高粘度である場合、油水をサイクロン室流入口１３で撹拌しても、油粒のエマルジョン化は小さい。   By jetting jet water toward the cyclone chamber inlet 13, the oil water before the inlet 13 is pushed into the cyclone chamber 10, and the oil deposited near the cyclone chamber inlet 13 is pushed into the water stream or attracted. Then, it flows into the cyclone chamber 10 from the water conduit 30. In addition, when oil is high viscosity, even if oil water is stirred by the cyclone chamber inflow port 13, emulsification of an oil particle is small.
