　ところで、磁性フロックを含む流体から磁性フロックを分離する方法として、遠心力を利用するハイドロサイクロン方式と磁気力を利用する磁気分離方式が存在する。 By the way, as a method for separating the magnetic floc from the fluid containing the magnetic floc, there are a hydrocyclone method using centrifugal force and a magnetic separation method using magnetic force.
　ハイドロサイクロン方式とは、磁性フロックを含む流体を、頂点を下方に向けた円錐形状容器の底面近くから内部に流入させる。そして、流入した流体を円錐形状の容器の内部で回転させ、比重差を利用して重い不純物を、円錐壁面を滑落させ円錐形状容器の頂点近傍から下方に除去する。そして、重い不純物を含まない処理水を上方から回収する方式である。
　磁気分離方式は、流体中の磁性フロックを磁石の磁気力により引きつけ、流体から磁性フロックを除去した処理水を得る方式である。 In the hydrocyclone system, a fluid containing magnetic floc is allowed to flow into the inside from near the bottom of the conical container with the apex directed downward. Then, the inflowing fluid is rotated inside the conical container, and heavy impurities are slid down the conical wall surface using the difference in specific gravity to remove downward from the vicinity of the apex of the conical container. And it is the system which collect | recovers the treated water which does not contain a heavy impurity from upper direction.
The magnetic separation method is a method for obtaining treated water from which magnetic flocs in the fluid are attracted by the magnetic force of the magnets to remove the magnetic flocs from the fluid.
　特許文献１では、磁性フロックを分離させるために、遠心力を利用する。しかし、当該分離性能を高めるには、遠心力を高めることを目的に流体の速度を上げる必要がある。しかし、それに伴い、磁気フロックが遠心力等により破壊される問題があった。 In Patent Document 1, centrifugal force is used to separate magnetic flocs. However, in order to improve the separation performance, it is necessary to increase the fluid velocity for the purpose of increasing the centrifugal force. However, along with this, there is a problem that the magnetic floc is broken by centrifugal force or the like.
　特許文献２では、磁性フロックを流体から分離させるために、サイクロンから排出された磁性微粒子を磁石の磁気力で壁面に吸着させ、流体から磁性微粒子を分離させる。その後、磁石を壁面から物理的に離すことで磁性微粒子に加わる磁気力を低減または解消する。これにより、壁面から磁性微粒子を離脱させて重力で落下させ、磁性フロックを回収している。この場合は、流体の遠心力と磁気力は、別々に働くため、敢えて一つの装置で行う必要がない。 In Patent Document 2, in order to separate the magnetic floc from the fluid, the magnetic fine particles discharged from the cyclone are attracted to the wall surface by the magnetic force of the magnet, and the magnetic fine particles are separated from the fluid. Thereafter, the magnetic force applied to the magnetic fine particles is reduced or eliminated by physically separating the magnet from the wall surface. As a result, the magnetic particles are separated from the wall surface and dropped by gravity to collect the magnetic floc. In this case, since the centrifugal force and magnetic force of the fluid work separately, it is not necessary to dare to use one device.
　また、磁気力はＮ極とＳ極の両方向に働くのに、一方向しか活用していないという問題がある。また、遠心力のみでは、磁性体を流体から分離するための遠心力が、粒径の小さい粒子は質量が小さいために充分働かず、分離性能が悪いという問題がある。
　また、磁性粒子はサイクロンの側面に付着させることで分離するため、最終的な分離を行うために出口付近のバルブの開閉や、磁場印加手段の移動による磁気力の低減という動作を用いる。そのため、連続的な動作には、不向きであるという問題もある。 In addition, the magnetic force works in both directions of the N pole and the S pole, but there is a problem that only one direction is utilized. In addition, with only the centrifugal force, there is a problem that the centrifugal force for separating the magnetic substance from the fluid does not work satisfactorily due to the small mass of the particles having a small particle size and the separation performance is poor.
Further, since the magnetic particles are separated by adhering to the side surface of the cyclone, an operation of opening / closing a valve near the outlet or reducing magnetic force by moving the magnetic field applying means is used for final separation. Therefore, there is a problem that it is not suitable for continuous operation.
　特許文献３では、磁性フロックを分離させるために、磁気力を利用している。しかし、膜で磁性フロックを分離した後、磁気力で磁性フロックを分離する。磁性フロックを破壊することなく、膜で分離するために、流速を高めることはできないという問題がある。  In Patent Document 3, magnetic force is used to separate magnetic flocs. However, after the magnetic floc is separated by the film, the magnetic floc is separated by the magnetic force. There is a problem that the flow rate cannot be increased because the magnetic flocs are separated without being destroyed.
　上述したように、磁性粒子や磁性フロックを含む流体から、磁性粒子や磁性フロックを分離するニーズは高い。しかし、磁性流体の大きさが小さく遠心力が十分働かない場合や、磁性フロックと流体との比重差が小さく、かつ、フロックの強度が低いため、高速で処理することができない等、磁性粒子や磁性フロックを流体から分離する場合、比重差分離やサイクロン等の遠心力分離が困難となっている。 As described above, there is a great need for separating magnetic particles and magnetic flocs from fluids containing magnetic particles and magnetic flocs. However, when the size of the magnetic fluid is small and centrifugal force does not work sufficiently, or because the difference in specific gravity between the magnetic floc and the fluid is small and the strength of the floc is low, it cannot be processed at high speed. When separating a magnetic floc from a fluid, it is difficult to separate a specific gravity difference or a centrifugal force such as a cyclone.
　本発明は上記実状に鑑み創案されたものであり、磁性粒子や磁性フロックを流体から確実に分離できる磁気サイクロン装置およびその処理方法の提供を目的とする。 The present invention has been devised in view of the above circumstances, and an object thereof is to provide a magnetic cyclone apparatus capable of reliably separating magnetic particles and magnetic floc from a fluid, and a treatment method thereof.
　前記課題を解決するため、第１の本発明の磁気サイクロン装置は、下方に頂点を向けた円錐台形状であり、側方に流入口を有する円筒形状の円筒台部と当該円筒台部の下方に連続して形成され、前記頂点近傍に下流出口が設けられる円錐形状の円錐部とを有するサイクロンと、前記円筒台部の中央部に配置され上流出口が設けられる円筒部と、前記円筒台部の外周近くに設けられる磁石とを備え、前記流入口から前記円筒台部内に流入する被処理液体に含有される磁性フロックを、前記円筒台部の内側面近傍に前記磁石で引き付けた後、前記下流出口から排出し、磁性フロックが除去された被処理液体を前記円筒部の上流出口から流出させている。
　第２の本発明の磁気サイクロン装置の処理方法は、第１の本発明を実現する方法である。 In order to solve the above-described problem, a magnetic cyclone device according to the first aspect of the present invention has a truncated cone shape with a vertex facing downward, a cylindrical cylindrical base portion having an inflow port on a side, and a lower portion of the cylindrical base portion. A cyclone having a conical conical portion formed downstream of the apex and provided with a downstream outlet in the vicinity of the apex, a cylindrical portion disposed in the center of the cylindrical base portion and provided with an upstream outlet, and the cylindrical base portion A magnetic floc contained in the liquid to be treated flowing into the cylindrical base portion from the inflow port and attracted by the magnet near the inner side surface of the cylindrical base portion, The liquid to be treated, which is discharged from the downstream outlet and from which the magnetic floc has been removed, flows out from the upstream outlet of the cylindrical portion.
The processing method of the magnetic cyclone device according to the second aspect of the present invention is a method for realizing the first aspect of the present invention.
　本発明によれば、磁性粒子や磁性フロックを流体から確実に分離できる磁気サイクロン装置およびその処理方法を提供できる。 According to the present invention, it is possible to provide a magnetic cyclone apparatus that can reliably separate magnetic particles and magnetic flocs from a fluid and a processing method thereof.

　本発明の磁気サイクロン装置１Ｓ（図１参照）は、高速水処理装置における凝集磁気分離とサイクロン分離とを融合することにより、汚濁水を処理する高速、高信頼、高性能を可能とする汚濁水処理装置である。 The magnetic cyclone apparatus 1S of the present invention (see FIG. 1) is a polluted water that enables high speed, high reliability, and high performance to treat polluted water by fusing the agglomeration magnetic separation and cyclone separation in the high speed water treatment apparatus. It is a processing device.
　そのため、磁気サイクロン装置１Ｓは、磁性フロックを破壊することがない低速（例えば、０．２ｍ/s以下）で磁性フロックを分離するために、流体力に加えて磁気力を利用する。汚濁水中に磁性フロックを作る。そして、磁性フロックに磁気力による吸引力を加えることで、サイクロン１内での旋回運動の流速がほぼゼロとなるサイクロン１の側面近傍に、磁性フロックが引きつけられる。これにより、磁性粒子や磁性フロックは、比重が水より重いため自重でサイクロン１の側面の下方が縮径した円錐面に沿って下降し、排出される。 Therefore, the magnetic cyclone device 1S uses a magnetic force in addition to a fluid force in order to separate the magnetic floc at a low speed (for example, 0.2 m / s or less) that does not destroy the magnetic floc. Make magnetic frock in polluted water. Then, by applying an attractive force by magnetic force to the magnetic floc, the magnetic floc is attracted to the vicinity of the side surface of the cyclone 1 where the flow velocity of the turning motion in the cyclone 1 becomes substantially zero. Thereby, since the specific gravity is heavier than water, a magnetic particle and a magnetic floc descend | fall along the conical surface where the lower part of the side surface of the cyclone 1 was reduced in diameter, and are discharged | emitted.
　さらに、電磁石５の磁気力はＮ極とＳ極の磁極５ａ、５ｂで大きい。そこで、サイクロン１近くに電磁石５の磁極５ａ、５ｂの何れかを配置することにより、電磁石５の磁気力を有効に利用し、少ない電流で効率の良い、磁性フロックの分離処置が可能となる。
　以下、本発明の実施形態について、適宜図面を参照しながら詳細に説明する。 Further, the magnetic force of the electromagnet 5 is large at the N-pole and S-pole magnetic poles 5a and 5b. Therefore, by disposing any one of the magnetic poles 5a and 5b of the electromagnet 5 near the cyclone 1, the magnetic force of the electromagnet 5 can be effectively used, and the magnetic floc can be separated efficiently with a small current.
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate.

　急速攪拌装置３２は、磁性体、凝集剤が供給された汚濁水を急速に攪拌し、マイクロフロックを作る。 The magnetic body supply device 30 applies a magnetic body to the liquid to be processed flowing through the pipe k1 in order to create a magnetic floc.

　浮遊物質、アオコ、油、重金属、プランクトン等を含む被処理液の流体１００が配管ｋ１内を任意の速度で流れてくる。配管ｋ１内の流体１００に磁性体供給装置３０、凝集剤供給装置３１からそれぞれ磁性体３０ｓ、凝集剤３１ｓを任意の濃度で添加する。なお、磁性体３０ｓ、凝集剤３１ｓの添加順序は逆でも構わない。 The magnetic cyclone apparatus 1S is an apparatus that attracts a floc containing a magnetic material from a liquid to be processed by an electromagnet 5 and separates the floc into a processing liquid other than the floc. Processing liquids other than floc are acquired.
A fluid 100 of the liquid to be treated including suspended matter, aquatic oil, oil, heavy metal, plankton, etc. flows through the pipe k1 at an arbitrary speed. Magnetic material 30s and coagulant 31s are added to the fluid 100 in the pipe k1 from the magnetic material supply device 30 and the coagulant supply device 31, respectively, at arbitrary concentrations.

On the other hand, the fluid from which the magnetic floc has been removed flows out from the upstream outlet 3 of the upper cylindrical portion 1e and is acquired.
　なお、急速攪拌装置３２の攪拌器３３で攪拌され、全ての数十μｍ程度のマイクロフロックに、磁性体３０ｓが含有されている場合は、無機凝集剤であるポリマー３６ｓを添加し、緩速攪拌装置３４の攪拌器３５で攪拌し、粒径１００μｍ以上の大きな磁性フロックを作る工程は設けなくともよい。 In addition, when the magnetic substance 30s is contained in all the micro flocs of about several tens of μm after being stirred by the stirrer 33 of the rapid stirring device 32, the polymer 36s as an inorganic flocculant is added and the stirring is performed slowly. There is no need to provide a step of stirring with the stirrer 35 of the apparatus 34 to produce a large magnetic floc having a particle size of 100 μm or more.

　上円筒部１ｅは、内面が円筒形状をもつ。上円筒部１ｅは、円筒台部１ｂの中央に設けられる。上円筒部１ｅは、下方が逆円錐部１ｃの内部または円筒台部１ｂの内部に開口され、上方が上流出口３として処理水回収部（図示せず）に連通されている。 The inverted conical portion 1c has a shape in which the inner surface thereof is an inverted cone, and the bottom surface located above has a shape corresponding to the lower surface of the cylindrical base portion 1b, and is continuously formed below the cylindrical base portion 1b. .
The inner surface of the lower cylindrical portion 1d has a cylindrical shape. The upper portion of the lower cylindrical portion 1d communicates with the inverted conical portion 1c, and the lower portion thereof is opened as the downstream outlet 4.
The upper cylindrical portion 1e has a cylindrical inner surface. The upper cylindrical part 1e is provided in the center of the cylindrical base part 1b. The upper cylindrical part 1e is opened at the lower part to the inside of the inverted conical part 1c or the cylindrical base part 1b, and the upper part is communicated with the treated water recovery part (not shown) as the upstream outlet 3.
　サイクロン１の円筒台部１ｂの外周近くに電磁石５のＳ極、Ｎ極の磁極５ａ、５ｂのうち一方の磁極５ａが配置されている。具体的には、電磁石５のＳ極またはＮ極がサイクロン１の一方側の流入口２に対して、他方側（反対側）に位置するように設けられている。
　電磁石５に電流が流されることにより、磁場５、６が生じ、強い磁気力がＳ極とＮ極の両磁極５ａ、５ｂに発生する。 Near the outer periphery of the cylindrical base portion 1b of the cyclone 1, one of the S poles and N poles 5a and 5b of the electromagnet 5 is disposed. Specifically, the S pole or N pole of the electromagnet 5 is provided on the other side (opposite side) with respect to the inlet 2 on one side of the cyclone 1.
When a current is passed through the electromagnet 5, magnetic fields 5 and 6 are generated, and a strong magnetic force is generated in both the S pole and the N pole 5a and 5b.
　磁性粒子や磁性フロックを含む被処理液の流体７が、不図示のポンプによって、流入口２から、入口部１ａを通過してサイクロン１の内部に流入する（図２の矢印α０）。流入した被処理液の流体７は、円筒台部１ｂの側壁面１ｂ１に案内されて、回って流れる（図２の実線矢印α１）。 The fluid 7 to be treated containing magnetic particles and magnetic flocs flows from the inlet 2 through the inlet 1a into the cyclone 1 (arrow α0 in FIG. 2) by a pump (not shown). The fluid 7 of the liquid to be treated which flows in is guided by the side wall surface 1b1 of the cylindrical base portion 1b and flows around (solid line arrow α1 in FIG. 2).
　この際、電磁石５の磁極５ａ、５ｂの磁気力によって、流体７に含まれる磁性粒子や磁性フロックは円筒台部１ｂの側壁面１ｂ１に向けて引き付けられる。つまり、磁気による停止力が働く。
　そして、磁性粒子や磁性フロックは磁性粒子、磁性フロック以外の流体７より比重が重いので、破線矢印α２のように、磁気サイクロン１の円錐側壁９に沿って下降し、下流出口４を通過して排出される（図２の矢印α５）。 At this time, magnetic particles and magnetic flocs contained in the fluid 7 are attracted toward the side wall surface 1b1 of the cylindrical base portion 1b by the magnetic force of the magnetic poles 5a and 5b of the electromagnet 5. That is, the magnetic stopping force works.
Since the specific gravity of the magnetic particles and magnetic flocs is heavier than that of the fluid 7 other than the magnetic particles and magnetic flocs, the magnetic particles and magnetic flocs descend along the conical side wall 9 of the magnetic cyclone 1 and pass through the downstream outlet 4 as indicated by the broken arrow α2. It is discharged (arrow α5 in FIG. 2).
　一方、磁性粒子や磁性フロック以外の水等の流体７ａは非磁性体であり、磁気力の影響を受けず、つまり磁気による停止力は働かず、しかも流体７より比重が軽い。そのため、遠心力を受けて円筒台部１ｂの側壁面１ｂ１に案内されて上向きに回転する流れとなる（図２の矢印α３）。そして、円筒形状の上円筒部１ｅに流入して廻って流れ上昇し、上流出口３より排出される（図２の矢印α４）。これにより、磁性粒子や磁性フロックを含む流体７は、磁性粒子や磁性フロックと、磁性粒子、磁性フロック以外の流体７ａとに分離される。 On the other hand, the fluid 7a such as water other than the magnetic particles and the magnetic floc is a non-magnetic material, and is not affected by the magnetic force, that is, the magnetic stopping force does not work, and the specific gravity is lighter than that of the fluid 7. Therefore, it receives a centrifugal force and is guided by the side wall surface 1b1 of the cylindrical base portion 1b to rotate upward (arrow α3 in FIG. 2). And it flows into the upper cylindrical part 1e of the cylindrical shape, flows up, and is discharged from the upstream outlet 3 (arrow α4 in FIG. 2). Thereby, the fluid 7 containing the magnetic particles and the magnetic floc is separated into the magnetic particles and the magnetic floc and the fluid 7a other than the magnetic particles and the magnetic floc.
　図３は、実施形態１の磁気サイクロン装置を上方から見た構成例を示す。
　サイクロン１の流入口２から侵入した流体７中の磁性粒子または磁性フロック１０、１１、１２は、流体力および電磁石５によって発生した磁気力によって、引っ張られ実線の細い矢印α０の方向に進行し、磁性粒子または磁性フロック２０、２１、２２のように、サイクロン１の内周面の側壁面１ｂ１近くに移動する。側壁面１ｂ１周辺は摩擦により流速がゼロに近い低速のため、さらには磁気による停止力により磁性粒子または磁性フロック２０、２１、２２は、他の流体７の流れに乗ることはできず、側壁面１ｂ１に付着するかその近傍に存在する。
　磁性粒子または磁性フロック２０、２１、２２は、比重が１より大きいので、流体７中から逆円錐部１ｃの円錐側壁９に沿って自然落下し、下流出口４から排出される。 FIG. 3 shows a configuration example of the magnetic cyclone device according to the first embodiment viewed from above.
Magnetic particles or magnetic flocs 10, 11, 12 in the fluid 7 entering from the inlet 2 of the cyclone 1 are pulled by the fluid force and the magnetic force generated by the electromagnet 5 and travel in the direction of the thin solid arrow α 0, Like the magnetic particles or the magnetic flocs 20, 21, 22, the cyclone 1 moves near the side wall surface 1b1 of the inner peripheral surface. Since the flow velocity around the side wall surface 1b1 is close to zero due to friction, the magnetic particles or the magnetic flocs 20, 21, and 22 cannot get on the flow of other fluids 7 due to the magnetic stopping force. It adheres to 1b1 or exists in the vicinity thereof.
Since the magnetic particles or the magnetic flocs 20, 21, 22 have a specific gravity larger than 1, they naturally fall from the fluid 7 along the conical side wall 9 of the inverted conical portion 1 c and are discharged from the downstream outlet 4.
　以上のことから、流入口２から流入する流体７の流量をＱ１とし、下流出口４（図２参照）から排出される磁性粒子や磁性粒子が含まれる磁性フロックの流量をＱ２とし、上流出口３（図２参照）から排出される処理水（磁性粒子や磁性フロック以外の水等の流体７ａ）の流量をＱ３とすると、
　　　Ｑ１＝Ｑ２＋Ｑ３
　と表される。 From the above, the flow rate of the fluid 7 flowing in from the inflow port 2 is Q1, the flow rate of magnetic particles discharged from the downstream outlet 4 (see FIG. 2) and the magnetic floc containing magnetic particles is Q2, and the upstream outlet 3 When the flow rate of treated water (fluid 7a such as water other than magnetic particles and magnetic floc) discharged from (see FIG. 2) is Q3,
Q1 = Q2 + Q3
It is expressed.
　石油等の水を利用した液状物質の生産において、生産物は、水と混合した状態、つまり、随伴水という形で生産される。さらに、生産物が液体の場合や、下水処理場や藻類培養場等でも水との比重差が少ない物質を水から分離する場合等、比重差や遠心力を利用した分離方法では、効率よい分離は困難である。
　そこで、実施形態１では、磁性粒子や磁性粉を石油や藻類と凝集させて、フロックを作り、分離することで、高性能な分離を可能としている。 In the production of liquid substances using water such as petroleum, the product is produced in a mixed state with water, that is, in the form of accompanying water. In addition, separation methods using specific gravity differences or centrifugal force, such as when the product is a liquid, or when separating substances with small specific gravity differences from water, such as sewage treatment plants and algae culture plants, are effective separations. It is difficult.
Thus, in the first embodiment, high-performance separation is possible by aggregating magnetic particles and magnetic powder with petroleum and algae to form and separate flocs.
　上記構成によれば、磁性粒子や磁性フロックを連続的にサイクロン１で分離するため、サイクロン１に入ってくる磁性粒子や磁性フロックの移動方向と同じ方向、または直交方向に電磁石５の磁極５ａ、５ｂの何れかの磁気力で引っ張ることで、磁性粒子や磁性フロックをサイクロン１の側壁面１ｂ１近傍に引き付ける。 According to the above configuration, since the magnetic particles and the magnetic floc are continuously separated by the cyclone 1, the magnetic poles 5a of the electromagnet 5 are arranged in the same direction as, or perpendicular to, the moving direction of the magnetic particles and the magnetic floc entering the cyclone 1. The magnetic particles and the magnetic floc are attracted to the vicinity of the side wall surface 1b1 of the cyclone 1 by pulling with any one of the magnetic forces 5b.
　サイクロン１の側壁面１ｂ１近傍の流速はゼロに近いため、さらには磁気力により磁性粒子や磁性フロックの速度をほぼゼロに落とすことで、磁性粒子や磁性フロックは、逆円錐部１ｃの円錐側壁９に落下する。円錐側壁９は、重力方向に対して、斜めの傾斜があるため、磁性粒子や磁性フロックは、重力によって、円錐側壁９に沿って下降する。その結果、磁性粒子や磁性フロックは、サイクロン１の側面に沿って下降して下流出口４から排出される。 Since the flow velocity in the vicinity of the side wall surface 1b1 of the cyclone 1 is close to zero, the magnetic particles and the magnetic flocs are further reduced to zero by the magnetic force, so that the magnetic particles and the magnetic flocs become conical side walls 9 of the inverted conical portion 1c. Fall into. Since the conical side wall 9 has an oblique inclination with respect to the direction of gravity, the magnetic particles and the magnetic flocs descend along the conical side wall 9 due to gravity. As a result, the magnetic particles and the magnetic floc descend along the side surface of the cyclone 1 and are discharged from the downstream outlet 4.
　よって、フィルタを用いることなく汚濁水中の異物、浮遊物質を除去し、浄化水を取り出すことができる。そのため、フィルタ（膜）を必要とせず取扱い性に優れ、フィルタ（膜）やフィルタ交換の作業がなく、ランニングコストが低い。
　従って、低コスト、取り扱い容易に汚濁水から浄化水を取り出すことが可能である。
　以上のことから、取扱い性に優れ低コストの磁気サイクロン装置１Ｓを実現することができる。 Therefore, it is possible to remove foreign substances and suspended substances in the polluted water without using a filter, and to take out purified water. Therefore, the filter (membrane) is not required and the handling is excellent, the filter (membrane) and the filter are not replaced, and the running cost is low.
Therefore, it is possible to take out purified water from the polluted water with low cost and easy handling.
From the above, it is possible to realize a magnetic cyclone device 1S that is excellent in handleability and low in cost.

　図４に、実施形態２に係る磁気サイクロン装置を側方から見た内部構成例を示す。
　実施形態２の磁気サイクロン装置２Ｓは、第１サイクロン２１Ａと第２サイクロン２１Ｂとが、電磁石２５を挟んで配置される。第１・第２サイクロン２１Ａ、２１Ｂは、プラスチック、アルミニウムなどの非磁性体で構成されている。 << Embodiment 2 >>
FIG. 4 shows an internal configuration example of the magnetic cyclone device according to the second embodiment viewed from the side.
In the magnetic cyclone device 2S of the second embodiment, a first cyclone 21A and a second cyclone 21B are arranged with an electromagnet 25 interposed therebetween. The first and second cyclones 21A and 21B are made of a nonmagnetic material such as plastic or aluminum.
　電磁石２５はＳ極とＮ極の磁極２５ａ、２５ｂをもつ。そこで、電磁石２５の磁極２５ａ、２５ｂの何れか一方の磁極を第１サイクロン２１Ａに対向して配置し、何れか他方の磁極を第２サイクロン２１Ｂに対向して配置している。
　磁気サイクロン装置２Ｓにおいて、その他の構成は、実施形態１と同様であるから、同様な構成要素には２０番台の符号を付して示し、詳細な説明は省略する。 The electromagnet 25 has S poles and N poles 25a and 25b. Therefore, one of the magnetic poles 25a and 25b of the electromagnet 25 is disposed to face the first cyclone 21A, and the other magnetic pole is disposed to face the second cyclone 21B.
In the magnetic cyclone device 2S, the other configuration is the same as that of the first embodiment, and therefore, the same components are denoted by reference numerals in the 20th order, and detailed description thereof is omitted.
　第１サイクロン２１Ａは、第１入口部２１ａ１と第１円筒台部２１ｂ１、第１逆円錐部２１ｃ１と、第１下円筒部２１ｄ１と第１上円筒部２１ｅ１とを有する。
　第１下円筒部２１ｄ１には、第１下流出口２４ａが設けられる。 The first cyclone 21A includes a first inlet portion 21a1, a first cylindrical base portion 21b1, a first inverted conical portion 21c1, a first lower cylindrical portion 21d1, and a first upper cylindrical portion 21e1.
A first downstream outlet 24a is provided in the first lower cylindrical portion 21d1.
　第１上円筒部２１ｅ１は、内面が円筒形状をもつ。第１上円筒部２１ｅ１は、第１円筒台部２１ｂ１の中央に形成される。第１上円筒部２１ｅ１は、下方が第１逆円錐部２１ｃ１または第１円筒台部２１ｂ１の内部に開口され、上方が第１上流出口２３ａとして処理水回収部（図示せず）に連通されている。 The inner surface of the first upper cylindrical portion 21e1 has a cylindrical shape. The first upper cylindrical portion 21e1 is formed at the center of the first cylindrical base portion 21b1. The lower part of the first upper cylindrical part 21e1 is opened inside the first inverted conical part 21c1 or the first cylindrical base part 21b1, and the upper part is communicated with a treated water recovery part (not shown) as a first upstream outlet 23a. Yes.
　同様に、第２サイクロン２１Ｂは、第２入口部２１ａ２と第２円筒台部２１ｂ３、第２逆円錐部２１ｃ２と、第２下円筒部２１ｄ２と第２上円筒部２１ｅ２とを有する。第２下円筒部２１ｄ２には、第２下流出口２４ｂが設けられる。第２上円筒部２１ｅ２は、内面が円筒形状をもつ。第２上円筒部２１ｅ２は、第２円筒台部２１ｂ３の中央に形成される。第２上円筒部２１ｅ２は、下方が第２逆円錐部２１ｃ２または第２円筒台部２１ｂ３の内部に開口され、上方が第２上流出口２３ｂとして処理水回収部（図示せず）に連通されている。 Similarly, the second cyclone 21B includes a second inlet portion 21a2, a second cylindrical base portion 21b3, a second inverted conical portion 21c2, a second lower cylindrical portion 21d2, and a second upper cylindrical portion 21e2. A second downstream outlet 24b is provided in the second lower cylindrical portion 21d2. The inner surface of the second upper cylindrical portion 21e2 has a cylindrical shape. The second upper cylindrical portion 21e2 is formed at the center of the second cylindrical base portion 21b3. The lower part of the second upper cylindrical part 21e2 is opened inside the second inverted conical part 21c2 or the second cylindrical base part 21b3, and the upper part is communicated with a treated water recovery part (not shown) as a second upstream outlet 23b. Yes.
　磁性粒子や磁性フロックを含む流体１０３、１０４は、それぞれ、第１サイクロン２１Ａの第１流入口２２ａと第２サイクロン２１Ｂの第１流入口２２ｂから、第１円筒台部２１ｂ１と第２円筒台部２１ｂ３とに反対方向から流入する。
　第１サイクロン２１Ａに流入した流体１０３および第２サイクロン２１Ｂに流入した流体１０４が進む方向は、電磁石２５の磁極２５ａ、２５ｂに向かう方向である。電磁石２５は、制御部２Ｃにより電流の制御が行われる。 The fluids 103 and 104 containing magnetic particles and magnetic flocs are respectively supplied from the first inlet 22a of the first cyclone 21A and the first inlet 22b of the second cyclone 21B from the first cylindrical base 21b1 and the second cylindrical base. 21b3 from the opposite direction.
The direction in which the fluid 103 flowing into the first cyclone 21A and the fluid 104 flowing into the second cyclone 21B travel is the direction toward the magnetic poles 25a and 25b of the electromagnet 25. The electromagnet 25 is controlled in current by the control unit 2C.
　第１サイクロン２１Ａ内の流体１０３の磁性粒子や磁性フロックは、電磁石２５の一方の磁極２５ａに発生する磁気力で、第１円筒台部２１ｂ１の第１側壁面２１ｂ２に引き付けられ、流速が大幅に低下する。 The magnetic particles and magnetic floc of the fluid 103 in the first cyclone 21A are attracted to the first side wall surface 21b2 of the first cylindrical base portion 21b1 by the magnetic force generated in one magnetic pole 25a of the electromagnet 25, and the flow velocity is greatly increased. descend.
　そして、第１サイクロン２１Ａの第１側壁面２１ｂ２に引き付けられた磁性粒子や磁性フロックは、水等の流体より比重が大きいので、第１逆円錐部２１ｃ１を矢印α２２ａに示すように回転しながら落下する。
　最終的に、磁性粒子や磁性フロックは、第１サイクロン２１Ａの下流出口２４ａから排出される（図４の矢印α２５ａ）。 Since the magnetic particles and magnetic floc attracted to the first side wall surface 21b2 of the first cyclone 21A have a specific gravity greater than that of fluid such as water, the first reverse cone portion 21c1 is rotated while rotating as indicated by an arrow α22a. To do.
Finally, the magnetic particles and the magnetic floc are discharged from the downstream outlet 24a of the first cyclone 21A (arrow α25a in FIG. 4).
　一方、磁性粒子や磁性フロックが除去された流体１０３ａは比重が流体１０３より軽いので、流入する流体１０３に押され、矢印α２３ａのように、らせん状の流れとなって上昇し、第１上円筒部２１ｅ１の第１上流出口２３ａから排出される（図４の矢印α２４ａ）。 On the other hand, the fluid 103a from which magnetic particles and magnetic flocs have been removed has a specific gravity lighter than that of the fluid 103, so that it is pushed by the inflowing fluid 103 and rises in a spiral flow as indicated by the arrow α23a. The gas is discharged from the first upstream outlet 23a of the portion 21e1 (arrow α24a in FIG. 4).
　同様に、第２サイクロン２１Ｂ内の流体１０４の磁性粒子や磁性フロックは、電磁石２５の他方の磁極２５ｂに発生する磁気力で、第２サイクロン２１Ｂの第２側壁面２１ｂ４に引き付けられ、流速が大幅に低下する。磁性粒子や磁性フロックと流体１０４ａとの速度差が生じる。 Similarly, the magnetic particles and magnetic floc of the fluid 104 in the second cyclone 21B are attracted to the second side wall surface 21b4 of the second cyclone 21B by the magnetic force generated in the other magnetic pole 25b of the electromagnet 25, and the flow velocity is greatly increased. To drop. A speed difference occurs between the magnetic particles and magnetic floc and the fluid 104a.
　そして、第２サイクロン２１Ｂの第２側壁面２１ｂ４に引き付けられた磁性粒子や磁性フロックは、水等の流体より比重が大きいので、逆円錐部２１ｃ２を矢印α２２ｂに示すように回転しながら落下する。
　最終的に、磁性粒子や磁性フロックは、第２サイクロン２１Ｂの第２下流出口２４ｂから排出される（図４の矢印α２５ｂ）。 Since the magnetic particles and magnetic floc attracted to the second side wall surface 21b4 of the second cyclone 21B have a specific gravity greater than that of fluid such as water, the inverted cone portion 21c2 falls while rotating as indicated by an arrow α22b.
Finally, the magnetic particles and the magnetic floc are discharged from the second downstream outlet 24b of the second cyclone 21B (arrow α25b in FIG. 4).
　一方、磁性粒子や磁性フロックが除去された流体１０４ａは比重が流体１０４より軽いので、流入する流体１０４に押され、矢印α２３ｂのように、らせん状の流れとなって上昇し、第２上円筒部２１ｅ２の第２上流出口２３ｂから排出される（図４の矢印α２４ｂ）。 On the other hand, the fluid 104a from which the magnetic particles and magnetic flocs have been removed has a specific gravity lighter than that of the fluid 104, so that it is pushed by the inflowing fluid 104 and rises in a spiral flow as indicated by the arrow α23b. The gas is discharged from the second upstream outlet 23b of the portion 21e2 (arrow α24b in FIG. 4).
＜磁気サイクロン装置２Ｓの制御パターン＞
　図５は、磁気サイクロン装置の制御パターンの例を示す。図５の横軸に（経過）時間（Ｔ）を示し、縦軸に電流（Ｉ）の大きさを示す。
　電磁石２５に磁気力を発生させるために、電磁石２５に加える電流のパターンの例を図５に示す。 <Control pattern of magnetic cyclone device 2S>
FIG. 5 shows an example of a control pattern of the magnetic cyclone device. The horizontal axis of FIG. 5 shows (elapsed) time (T), and the vertical axis shows the magnitude of current (I).
An example of a pattern of current applied to the electromagnet 25 in order to generate a magnetic force in the electromagnet 25 is shown in FIG.
　一定の電流値を加える電流パターン２００は制御が簡単であるが、図４に示す第１サイクロン２１Ａの第１側壁面２１ｂ２と第２サイクロン２１Ｂの第２側壁面２１ｂ４とに流体中の磁性粒子や磁性フロックが付着し続けるおそれがある。そこで、制御パターンとしてはパルス的な電流パターン２０１が最適である。電流を印加する加電時間２０２、２０３、２０４、２０５、２０６、２０７は、基本的には同じ時間とするが、異なる時間に変化させることも可能ある。 The current pattern 200 for applying a constant current value is easy to control, but the magnetic particles in the fluid and the like on the first side wall surface 21b2 of the first cyclone 21A and the second side wall surface 21b4 of the second cyclone 21B shown in FIG. There is a risk that magnetic flocs will continue to adhere. Therefore, the pulse current pattern 201 is optimal as the control pattern. The heating times 202, 203, 204, 205, 206, and 207 for applying the current are basically the same time, but can be changed to different times.
　一方、電流を印加しない非加電時間２１０、２１１、２１２、２１３、２１４も基本的には同じ時間であるが、変化させることも可能である。
　被被処理液体中の磁性フロック等の濃度が同じとして、被処理液体の流体１０３、１０４の流速が遅いと第１サイクロン２１Ａと第２サイクロン２１Ｂとに流入する流体１０３、１０４中の磁性粒子や磁性フロック（処理すべき量）が少なくなる一方、被処理液体の流体１０３、１０４の流速が遅いと第１サイクロン２１Ａと第２サイクロン２１Ｂとに流入する流体１０３、１０４中の磁性粒子や磁性フロック（処理すべき量）が多くなる。 On the other hand, the non-heating times 210, 211, 212, 213, and 214 in which no current is applied are basically the same time, but can be changed.
Assuming that the concentration of magnetic flocs and the like in the liquid to be processed is the same, the magnetic particles in the fluids 103 and 104 flowing into the first cyclone 21A and the second cyclone 21B when the flow rates of the fluids 103 and 104 of the liquid to be processed are low While the magnetic flocs (amount to be processed) are reduced, the magnetic particles and magnetic flocs in the fluids 103 and 104 flowing into the first cyclone 21A and the second cyclone 21B when the flow rates of the fluids 103 and 104 of the liquid to be processed are low. (Amount to be processed) increases.
　そこで、加電時間２０２、２０３、２０４、２０５、２０６、２０７は、流入する流体の流速によって変化させる。流速に応じて、第１サイクロン２１Ａ内と第２サイクロン２１Ｂ内とを一周する時間とほぼ同じ時間であることが望ましい。 Therefore, the charging times 202, 203, 204, 205, 206, and 207 are changed depending on the flow velocity of the flowing fluid. It is desirable that the time is substantially the same as the time for making a round in the first cyclone 21A and the second cyclone 21B depending on the flow velocity.
　上記制御パターンは、間欠的に電磁石２５に電流を加えるので、磁性粒子や磁性フロックが第１サイクロン２１Ａの第１側壁面２１ｂ２と第２サイクロン２１Ｂの第２側壁面２１ｂ４とに、付着し続けることがない。そのため、流体１０３、１０４中の磁性粒子や磁性フロックを効果的にかつ確実に流体１０３、１０４中から除去できる。
　なお、以上説明した制御パターンは、実施形態１の磁気サイクロン装置１Ｓに適用してもよい。 Since the control pattern intermittently applies current to the electromagnet 25, the magnetic particles and the magnetic floc continue to adhere to the first side wall surface 21b2 of the first cyclone 21A and the second side wall surface 21b4 of the second cyclone 21B. There is no. Therefore, the magnetic particles and magnetic floc in the fluids 103 and 104 can be effectively and reliably removed from the fluids 103 and 104.
The control pattern described above may be applied to the magnetic cyclone device 1S of the first embodiment.
　実施形態２の構成によれば、電磁石２５は、第１サイクロン２１Ａの第１円筒台部２１ｂ１と第２サイクロン２１Ｂの第２円筒台部２１ｂ３との間に磁極２５ａ、２５ｂとを向けて設けられるので、電磁石２５が一つで済む。
　２つの第１サイクロン２１Ａ、第２サイクロン２１Ｂに対して一つの電磁石２５で済むので構成が簡素であり、磁気サイクロン装置２Ｓの低コスト化が可能である。 According to the configuration of the second embodiment, the electromagnet 25 is provided with the magnetic poles 25a and 25b facing between the first cylindrical base portion 21b1 of the first cyclone 21A and the second cylindrical base portion 21b3 of the second cyclone 21B. Therefore, only one electromagnet 25 is required.
Since one electromagnet 25 is sufficient for the two first cyclones 21A and the second cyclone 21B, the configuration is simple, and the cost of the magnetic cyclone device 2S can be reduced.
　また、磁気サイクロン装置２Ｓは、２つの第１サイクロン２１Ａ、第２サイクロン２１Ｂと一つの電磁石２５で構成できるので小型にできる。
　加えて、電磁石２５に間欠的に電流を流すことで、流入した磁性粒子や磁性フロックが第１・第２サイクロン２１Ａの第１・第２円筒台部２１ｂ１、２１ｂ３の各第１・第２側壁面２１ｂ２、２１ｂ４に付着し続けることが抑制される。
　従って、低コスト、小型であり、信頼性が高い磁気サイクロン装置２Ｓを実現できる。 Further, the magnetic cyclone device 2S can be made compact because it can be constituted by the two first cyclones 21A, the second cyclone 21B, and one electromagnet 25.
In addition, by passing an electric current intermittently through the electromagnet 25, the magnetic particles and the magnetic floc that flowed in are first and second sides of the first and second cylindrical base portions 21b1 and 21b3 of the first and second cyclones 21A. The adhesion to the wall surfaces 21b2 and 21b4 is suppressed.
Therefore, it is possible to realize a magnetic cyclone device 2S that is low in cost, small in size, and highly reliable.

　変形例１の磁気サイクロン装置３Ｓは、第１サイクロン３１Ａと第２サイクロン３１Ｂとで電磁石３５を挟んで配置される。そして、磁気サイクロン装置３Ｓは、第１サイクロン３１Ａの入口部３１ａ１の流入方向と第２サイクロン３１Ｂの入口部３１ａ２の流入方向とが逆方向に配置される。第１・第２サイクロン３１Ａ、３１Ｂは、プラスチック、アルミニウムなどの非磁性体で構成されている。 << Modification 1 >>
FIG. 6 shows a configuration example of the magnetic cyclone device according to the first modification viewed from above.
The magnetic cyclone device 3S of Modification 1 is arranged with an electromagnet 35 sandwiched between a first cyclone 31A and a second cyclone 31B. In the magnetic cyclone device 3S, the inflow direction of the inlet portion 31a1 of the first cyclone 31A and the inflow direction of the inlet portion 31a2 of the second cyclone 31B are arranged in opposite directions. The first and second cyclones 31A and 31B are made of a nonmagnetic material such as plastic or aluminum.
　電磁石３５は、それぞれの第１サイクロン３１Ａの第１入口部３１ａ１の流入方向（図６の矢印α３１）と第２サイクロン３１Ｂの入口部３１ａ２の流入方向（図６の矢印α３２）とに挟まれる位置に配置される。 The electromagnet 35 is sandwiched between the inflow direction of the first inlet portion 31a1 of each first cyclone 31A (arrow α31 in FIG. 6) and the inflow direction of the inlet portion 31a2 of the second cyclone 31B (arrow α32 in FIG. 6). Placed in.
　詳細には、電磁石３５の一方の磁極３５ａを第１サイクロン３１Ａの第１入口部３１ａ１の流入方向に対向させて第１円筒台部３１ｂ１の外周近傍に配置している。また、電磁石３５の他方の磁極３５ｂを第２サイクロン３１Ｂの入口部３１ａ２の流入方向に対向させて第２円筒台部３１ｂ３の外周近傍に配置している。
　その他の構成は、実施形態２の構成と同様であるので詳細な説明は省略する。 Specifically, one magnetic pole 35a of the electromagnet 35 is disposed in the vicinity of the outer periphery of the first cylindrical base portion 31b1 so as to face the inflow direction of the first inlet portion 31a1 of the first cyclone 31A. Further, the other magnetic pole 35b of the electromagnet 35 is disposed in the vicinity of the outer periphery of the second cylindrical base portion 31b3 so as to face the inflow direction of the inlet portion 31a2 of the second cyclone 31B.
Since other configurations are the same as those of the second embodiment, detailed description thereof is omitted.
　これにより、第１サイクロン３１Ａの第１入口部３１ａ１に流入する被処理液体の流体中の磁性粒子や磁性フロックが、流体の流れの力（図６の矢印α３１）に加えて電磁石３５の磁極３５ａの磁気力により引き付けられる。
　また、第２サイクロン３１Ｂの第２入口部３１ａ２に流入する被処理液体の流体中の磁性粒子や磁性フロックが、流体の流れの力（図６の矢印α３２）に加えて電磁石３５の磁極３５ｂの磁気力により引き付けられる。 As a result, the magnetic particles and the magnetic floc in the fluid of the liquid to be processed flowing into the first inlet portion 31a1 of the first cyclone 31A are added to the fluid flow force (arrow α31 in FIG. 6), and the magnetic pole 35a of the electromagnet 35. It is attracted by the magnetic force.
Further, the magnetic particles and the magnetic floc in the fluid of the liquid to be processed flowing into the second inlet 31a2 of the second cyclone 31B are added to the magnetic force 35b of the electromagnet 35 in addition to the fluid flow force (arrow α32 in FIG. 6). Attracted by magnetic force.
　そのため、第１サイクロン３１Ａの第１入口部３１ａ１から流入する流体中の磁性粒子や磁性フロックが、電磁石３５の磁極３５ａの磁気力により、第１円筒台部３１ｂ１の第１側壁面３１ｂ２の側に引き付けられ、第１側壁面３１ｂ２に付着または第１側壁面３１ｂ２近傍に存在する。 Therefore, the magnetic particles and magnetic floc in the fluid flowing in from the first inlet portion 31a1 of the first cyclone 31A are moved toward the first side wall surface 31b2 of the first cylindrical base portion 31b1 by the magnetic force of the magnetic pole 35a of the electromagnet 35. The attracted and attached to the first side wall surface 31b2 or the vicinity of the first side wall surface 31b2.
　同様に、第２サイクロン３１Ｂの第２入口部３１ａ２から流入する流体中の磁性粒子や磁性フロックが、電磁石３５の磁極３５ｂの磁気力により、第２円筒台部３１ｂ３の第２側壁面３１ｂ４の側に引き付けられ、第２側壁面３１ｂ４に付着または第２側壁面３１ｂ４近傍に存在する。 Similarly, the magnetic particles and magnetic floc in the fluid flowing from the second inlet portion 31a2 of the second cyclone 31B are moved to the second side wall surface 31b4 side of the second cylindrical base portion 31b3 by the magnetic force of the magnetic pole 35b of the electromagnet 35. And attached to the second side wall surface 31b4 or in the vicinity of the second side wall surface 31b4.
　その後、第１サイクロン３１Ａの第１側壁面３１ｂ２に付着または第１側壁面３１ｂ２近傍に存在する磁性粒子や磁性フロックは、重力により不図示の第１逆円錐部の円錐側壁を滑落して、第１下流出口３４ａから排出される。一方、磁性粒子や磁性フロックが除去された流体は、第１上流出口３３ａから取水される。 Thereafter, the magnetic particles and the magnetic flocs adhering to the first side wall surface 31b2 of the first cyclone 31A or existing in the vicinity of the first side wall surface 31b2 slide down on the conical side wall of the first inverted conical portion (not shown) due to gravity. 1 is discharged from the downstream outlet 34a. On the other hand, the fluid from which the magnetic particles and the magnetic floc have been removed is taken from the first upstream outlet 33a.
　同様に、第２サイクロン３１Ｂの第２側壁面３１ｂ４に付着または第２側壁面３１ｂ４近傍に存在する磁性粒子や磁性フロックは、重力により不図示の第２逆円錐部の円錐側壁を滑落して、第２下流出口３４ｂから排出される。一方、磁性粒子や磁性フロックが除去された流体は、第２上流出口３３ｂから取水される。 Similarly, magnetic particles and magnetic flocks attached to the second side wall surface 31b4 of the second cyclone 31B or present in the vicinity of the second side wall surface 31b4 slide down the conical side wall of the second inverted conical portion (not shown) due to gravity, It is discharged from the second downstream outlet 34b. On the other hand, the fluid from which the magnetic particles and magnetic floc have been removed is taken from the second upstream outlet 33b.
　上記構成によれば、第１サイクロン３１Ａの第１入口部３１ａ１の流入方向と第２サイクロン３１Ｂの第２入口部３１ａ２の流入方向とが逆方向である。
　そして、電磁石３５の磁極３５ａと磁極３５ｂを第１サイクロン３１Ａの第１入口部３１ａ１の流入方向と第２サイクロン３１Ｂの第２入口部３１ａ２の流入方向とに向かい合う位置に配置する。
　そのため、流体中の磁性粒子や磁性フロックがそれぞれ第１円筒台部３１ｂ１の第１側壁面３１ｂ２と第２円筒台部３１ｂ３の第２側壁面３１ｂ４とに、流体の流れの力（図６の矢印α３１、α３２）に加えて電磁石３５の磁極３５、３５ｂの各引力により引き寄せられる。
　従って、効果的に流体中の磁性粒子や磁性フロックを流体から分離することができる。 According to the above configuration, the inflow direction of the first inlet portion 31a1 of the first cyclone 31A is opposite to the inflow direction of the second inlet portion 31a2 of the second cyclone 31B.
And the magnetic pole 35a and the magnetic pole 35b of the electromagnet 35 are arrange | positioned in the position facing the inflow direction of the 1st entrance part 31a1 of 1st cyclone 31A, and the inflow direction of the 2nd entrance part 31a2 of 2nd cyclone 31B.
Therefore, the magnetic particles and the magnetic flocs in the fluid flow on the first side wall surface 31b2 of the first cylindrical base part 31b1 and the second side wall surface 31b4 of the second cylindrical base part 31b3 (arrows in FIG. 6). In addition to [alpha] 31 and [alpha] 32), the magnetic poles 35 and 35b of the electromagnet 35 are attracted to each other.
Therefore, magnetic particles and magnetic flocs in the fluid can be effectively separated from the fluid.
＜＜変形例２＞＞
　図７は、変形例２に係る磁気サイクロン装置を上方から見た構成例を示す。
　変形例２の磁気サイクロン装置４Ｓの第１サイクロン４１Ａと第２サイクロン４１Ｂは、図７に示すように、電磁石４５を挟んで対称に配置されている。第１・第２サイクロン４１Ａ、４１Ｂは、プラスチック、アルミニウムなどの非磁性体で構成されている。 << Modification 2 >>
FIG. 7 shows a configuration example of the magnetic cyclone device according to the second modification viewed from above.
As shown in FIG. 7, the first cyclone 41 </ b> A and the second cyclone 41 </ b> B of the magnetic cyclone device 4 </ b> S of Modification 2 are arranged symmetrically with the electromagnet 45 interposed therebetween. The first and second cyclones 41A and 41B are made of a nonmagnetic material such as plastic or aluminum.
　電磁石４５は、第１サイクロン４１Ａと第２サイクロン４１Ｂのそれぞれの第１入口部４１ａ１と第２入口部４１ａ２の各流入方向（図７の矢印α４１、α４２）に直交した位置に配置されている。変形例２では、磁気力は流体の流れに直交して、第１入口部４１ａ１および第２入口部４１ａ２の各最外面の流路に向かって該磁性粒子や磁性フロックを吸引する。この場合、流路の磁性粒子や磁性フロックが磁気力で第１側壁面４１ｂ２、第２側壁面４１ｂ４に固着する可能性は低いため、電磁石４５は永久磁石でも構わない。その他の構成は、実施形態２の構成と同様であるので詳細な説明は省略する。 The electromagnet 45 is disposed at a position orthogonal to each inflow direction (arrows α41 and α42 in FIG. 7) of the first inlet 41a1 and the second inlet 41a2 of the first cyclone 41A and the second cyclone 41B. In the second modification, the magnetic force is perpendicular to the fluid flow, and attracts the magnetic particles and magnetic flocs toward the channels on the outermost surfaces of the first inlet portion 41a1 and the second inlet portion 41a2. In this case, the electromagnet 45 may be a permanent magnet because there is a low possibility that the magnetic particles and the magnetic floc in the flow path are fixed to the first side wall surface 41b2 and the second side wall surface 41b4 by magnetic force. Since other configurations are the same as those of the second embodiment, detailed description thereof is omitted.
　磁気サイクロン装置４Ｓでは、電磁石４５が第１サイクロン４１Ａの第１円筒台部４１ｂ１と第２サイクロン４１Ｂの第２円筒台部４１ｂ３とに挟まれて配置される。
　そして、第１サイクロン４１Ａの第１入口部４１ａ１からの流入方向に対して、電磁石４５のＮ極とＳ極の何れか一方の磁極４５ａが交差する方向の略垂直方向であって第１円筒台部４１ｂ１の近傍に配置されている。 In the magnetic cyclone device 4S, the electromagnet 45 is disposed between the first cylindrical base part 41b1 of the first cyclone 41A and the second cylindrical base part 41b3 of the second cyclone 41B.
The first cylindrical base is substantially perpendicular to the direction in which one of the N and S poles of the electromagnet 45 intersects the inflow direction from the first inlet 41a1 of the first cyclone 41A. It arrange | positions in the vicinity of the part 41b1.
　また、第２サイクロン４１Ｂの第２入口部４１ａ２からの流入方向に対して、電磁石４５のＮ極とＳ極の何れか他方の磁極４５ｂが交差する方向の略垂直方向であって第２円筒台部４１ｂ３の近傍に配置されている。 Further, the second cylindrical base is substantially perpendicular to the direction in which the other magnetic pole 45b of the N pole and S pole of the electromagnet 45 intersects with the inflow direction from the second inlet portion 41a2 of the second cyclone 41B. It arrange | positions in the vicinity of the part 41b3.
　第１サイクロン４１Ａには、第１入口部４１ａ１から、被処理液体の磁性フロックを含有する流体が第１円筒台部４１ｂ１に流入する（図７の矢印α４１）。電磁石４５のＮ極とＳ極の何れか一方の磁極４５ａが、第１入口部４１ａ１からの被処理液体の磁性フロックを含有する流体の流入方向に交差する略垂直方向に配置され、流体中の磁性フロックを第１円筒台部４１ｂ１の第１側壁面４１ｂ２に向けて引き付ける。 In the first cyclone 41A, the fluid containing the magnetic floc of the liquid to be processed flows into the first cylindrical base 41b1 from the first inlet 41a1 (arrow α41 in FIG. 7). Either one of the N pole and the S pole of the electromagnet 45 is arranged in a substantially vertical direction intersecting the inflow direction of the fluid containing the magnetic floc of the liquid to be processed from the first inlet portion 41a1, and is in the fluid. The magnetic floc is attracted toward the first side wall surface 41b2 of the first cylindrical base portion 41b1.
　これにより、流体中の磁性フロックを第１側壁面４１ｂ２に付着または第１側壁面４１ｂ２近傍に存在させる。そして、磁性フロックは、重力により不図示の第１逆円錐部の円錐側壁を滑落して、第１下流出口４４ａから下方に排出される。
　一方、磁性粒子や磁性フロックが除去された流体は、第１上流出口４３ａから取水される。 As a result, the magnetic floc in the fluid adheres to the first side wall surface 41b2 or exists in the vicinity of the first side wall surface 41b2. The magnetic flock slides down on the conical side wall of the first inverted conical portion (not shown) due to gravity and is discharged downward from the first downstream outlet 44a.
On the other hand, the fluid from which the magnetic particles and magnetic floc have been removed is taken from the first upstream outlet 43a.
　第２サイクロン４１Ｂには、第２入口部４１ａ２から、被処理液体の磁性フロックを含有する流体が第２円筒台部４１ｂ３に流入する（図７の矢印α４２）。電磁石４５のＮ極とＳ極の何れか他方の磁極４５ｂが、第２入口部４１ａ２からの被処理液体の磁性フロックを含有する流体の流入方向に交差する略垂直方向に方向に配置され、流体中の磁性フロックを第２円筒台部４１ｂ３の第２側壁面４１ｂ４に向けて引き付ける。 In the second cyclone 41B, the fluid containing the magnetic floc of the liquid to be processed flows into the second cylindrical base 41b3 from the second inlet 41a2 (arrow α42 in FIG. 7). The other magnetic pole 45b of the N pole and the S pole of the electromagnet 45 is disposed in a direction substantially perpendicular to the inflow direction of the fluid containing the magnetic floc of the liquid to be processed from the second inlet portion 41a2, and the fluid The inside magnetic floc is attracted toward the second side wall surface 41b4 of the second cylindrical base portion 41b3.
　これにより、流体中の磁性フロックを第２側壁面４１ｂ４に付着または第２側壁面４１ｂ４近傍に存在させる。そして、磁性フロックは、重力により不図示の第２逆円錐部の円錐側壁を滑落して、第２下流出口４４ｂから下方に排出される。
　一方、磁性粒子や磁性フロックが除去された流体は、第２上流出口４３ｂから取水される。 As a result, the magnetic floc in the fluid adheres to the second side wall surface 41b4 or exists in the vicinity of the second side wall surface 41b4. The magnetic flock slides down the conical side wall of the second reverse conical portion (not shown) due to gravity and is discharged downward from the second downstream outlet 44b.
On the other hand, the fluid from which the magnetic particles and magnetic floc have been removed is taken from the second upstream outlet 43b.
　上記構成によれば、電磁石４５を第１サイクロン４１Ａの第１入口部４１ａ１の流入方向と第２サイクロン４１Ｂの第２入口部４１ａ２の流入方向とに略垂直な方向に電磁石４５のＮ極とＳ極の磁極４５ａ、４５ｂを配置する。そのため、流体中の磁性粒子や磁性フロックが、それぞれ第１円筒台部４１ｂ１の第１側壁面４１ｂ２と第２円筒台部４１ｂ３の第２側壁面４１ｂ４とに磁力により効果的に引き寄せられる。
　従って、流体中の磁性粒子や磁性フロックを流体から効果的に分離することができる。 According to the above configuration, the N pole of the electromagnet 45 and the S in the direction substantially perpendicular to the inflow direction of the first inlet portion 41a1 of the first cyclone 41A and the inflow direction of the second inlet portion 41a2 of the second cyclone 41B. Polar poles 45a and 45b are arranged. Therefore, the magnetic particles and the magnetic floc in the fluid are effectively attracted by the magnetic force to the first side wall surface 41b2 of the first cylindrical base part 41b1 and the second side wall surface 41b4 of the second cylindrical base part 41b3, respectively.
Therefore, magnetic particles and magnetic flocs in the fluid can be effectively separated from the fluid.
　なお、図７では、電磁石４５の磁極４５ａ、４５ｂが、第１サイクロン４１Ａの第１入口部４１ａ１からの流入方向と第２サイクロン４１Ｂの第２入口部４１ａ２からの流入方向とに略垂直の場合を説明したが、交差するように配置すれば必ずしも垂直でなくてもよい。 In FIG. 7, the magnetic poles 45a and 45b of the electromagnet 45 are substantially perpendicular to the inflow direction from the first inlet portion 41a1 of the first cyclone 41A and the inflow direction from the second inlet portion 41a2 of the second cyclone 41B. However, as long as they are arranged so as to cross each other, they are not necessarily vertical.
　なお、前記実施形態１、２、変形例１、２では、電磁石５、２５、３５、４５を例示して説明したが、電磁石５、２５、３５、４５に代えて永久磁石を用いてもよい。 In the first and second embodiments and the first and second modifications, the electromagnets 5, 25, 35, and 45 are described as examples. However, permanent magnets may be used instead of the electromagnets 5, 25, 35, and 45. .
　また、前記実施形態１、２、変形例１、２で説明した各構成を適宜組み合わせて構成してもよい。 Further, the configurations described in Embodiments 1 and 2 and Modifications 1 and 2 may be combined as appropriate.
　また、前記実施形態１、２、変形例１、２は、本発明の例を示したものであり、本発明は特許請求の範囲内で様々な具体的形態、変形形態が可能である。 The first and second embodiments and the first and second modified examples 1 and 2 show examples of the present invention, and the present invention can have various specific forms and modified forms within the scope of the claims.
　本発明では、磁性粒子や磁性粉を上記石油や藻類と凝集させて、フロックを作り、分離することで、高性能な分離が可能となる。従来、高効率な処理が困難であった石油生産現場や下水処理場、藻類等の培養施設での利用の可能性は高い。
　また、バラスト水の浄化装置にも活用が可能である。 In the present invention, high-performance separation is possible by agglomerating the magnetic particles and magnetic powder with the petroleum and algae to form and separate flocs. There is a high possibility of use in oil production sites, sewage treatment plants, and culture facilities such as algae, which have been difficult to achieve with high efficiency.
