Patent Document 1 discloses a solid-liquid separation device that improves the ability to separate impurities from raw water and prevents re-mixing of separated impurities into treated water.

JP 2011-83696 JP Japanese Unexamined Patent Publication No. 2005-21835 JP 2002-66375 A

  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.

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.

  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.

  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.

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.

  In patent document 3, in order to isolate | separate a magnetic floc, magnetic force is utilized. 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.

  As described above, there is a great need for separating magnetic particles and magnetic flocs from a fluid 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.

  The present invention has been devised in view of the above circumstances, and an object thereof is to provide a magnetic cyclone apparatus that can reliably separate magnetic particles and magnetic flocs from a fluid and a processing method therefor.

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.

  ADVANTAGE OF THE INVENTION According to this invention, the magnetic cyclone apparatus which can isolate | separate a magnetic particle and a magnetic floc from a fluid reliably, and its processing method can be provided.

  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.

  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.

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.

<< Embodiment 1 >>
In FIG. 1, the structural example of the purification system of the magnetic cyclone apparatus of Embodiment 1 is shown.
The purification system S of the first embodiment includes a magnetic substance supply device 30s, a flocculant supply device 31s, a rapid stirring device 32, a polymer supply device 36s, a slow stirring device 34, and a magnetic cyclone device 1S.

  The magnetic substance supply device 30s, the flocculant supply device 31s, the rapid stirring device 32, the slow stirring device 34, and the magnetic cyclone device 1S are connected via a pipe k (k1, k2, k3). The polluted water of the fluid that is the liquid to be treated flows through the pipe k. The polluted water is, for example, sewage, ballast water, oil, accompanying water containing heavy metals, water, water containing SS (Suspended Solid), and the like.

The magnetic body supply device 30s imparts a magnetic body to the liquid to be processed flowing through the pipe k1 in order to create a magnetic floc.
The flocculant supply device 31s supplies the flocculant to the liquid to be processed flowing through the pipe k1 in order to collect the floating substances and foreign matters in the liquid to be processed to form micro flocs. The micro floc is a mass having a diameter of 100 μm or less.
The rapid stirring device 32s rapidly stirs the polluted water supplied with the magnetic material and the flocculant to make micro flocs.

The polymer supply device 36s supplies a polymer as an inorganic flocculant in order to collect the micro flocs including the magnetic material and the micro flocs not including the magnetic material to make the floc including the magnetic material. A floc is a lump with a diameter of 1 mm or more.
The slow stirrer 34s collects the micro flocs containing the magnetic substance and the micro flocs not containing the magnetic substance from the polymer of the inorganic flocculant to make the flocs containing the magnetic substance, and the liquid to be treated flowing through the pipe k2 is collected. Stir gently.

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. The magnetic body 30 and the coagulant 31 are added to the fluid 100 in the pipe k1 at arbitrary concentrations from the magnetic body supply device 30s and the coagulant supply device 31s, respectively. The order of adding the magnetic body 30 and the flocculant 31 may be reversed.

The fluid 100 to which the magnetic body 30 and the flocculant 31 are added is stirred by the stirrer 33 of the rapid stirring device 32, and a micro floc having a particle size of about several tens of μm is formed.
Thereafter, the polymer 36 of the inorganic flocculant is added to the fluid 100 flowing through the pipe k2 from the polymer supply device 36s. The fluid 100 to which the polymer 36 has been added is stirred by the stirrer 35 of the slow stirring device 34, and a large magnetic floc having a particle size of 100 μm or more is created by the aggregation action of the polymer 36.

A fluid 7 containing magnetic floc flows into the cyclone 1. Near the outer periphery of the cyclone 1, any one of the magnetic poles 5a and 5b of the electromagnet 5 is disposed. The electromagnet 5 is controlled to be turned on / off by the controller 1C.
The magnetic floc in the fluid 7 flowing into the cyclone 1 is attracted to the magnetic pole 5 a of the electromagnet 5, separated from the fluid 7, falls downward by gravity, and is discharged from the downstream outlet 4. 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 1d and is acquired.

  In addition, when the magnetic substance 30 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 36 that is an inorganic flocculant is added and the stirring is performed slowly. It is not necessary to provide a process of stirring with the stirrer 35 of the apparatus 34 to create a large magnetic floc having a particle size of 100 μm or more.

<Magnetic cyclone device 1S>
FIG. 2 is a diagram illustrating a configuration of the magnetic cyclone device according to the first embodiment when viewed from the side.
A magnetic cyclone device 1S according to the first embodiment includes a cyclone 1 and an electromagnet 5. The cyclone 1 is made of a nonmagnetic material such as plastic or aluminum.
The cyclone 1 includes an inlet 2, an upstream outlet 3, and a downstream outlet 4. The cyclone 1 has an inlet portion 1a, a cylindrical base portion 1b, an inverted conical portion 1c, a lower cylindrical portion 1d, and an upper cylindrical portion 1e.

The inlet portion 1a has a cylindrical shape whose inner surface is a horizontal axis. One of the inlet portions 1a is the inflow port 2, and the other inner surface is communicated with a cylindrical base portion 1b having the following cylindrical shape.
The cylindrical base portion 1b and the reverse cone portion 1c form an inverted truncated cone portion whose apex is directed downward.
The inverted truncated cone part has an upper inner surface (side wall surface 1b1) having a cylindrical cylindrical part 1b, and a lower inner surface (conical sidewall 9) having an inverted conical inverted cone part 1c.

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.

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 the N pole of the electromagnet 5 is provided on the other side with respect to the one inlet 2 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.

  A fluid 7 to be treated containing magnetic particles and magnetic flocs flows from the inlet 2 into the cyclone 1 through the inlet 1a by an unillustrated pump (arrow α0 in FIG. 2). 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).

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).

  On the other hand, the fluid 7a such as water other than the magnetic particles and the magnetic floc is a non-magnetic material, is not affected by the magnetic force, that is, does not act as a magnetic stopping force, and has a lighter specific gravity than 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.

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.

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.

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.

  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.

  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.

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.

<< 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.

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.

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.

  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.

  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.

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 1C.

  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.

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).

  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. It is discharged from the first upstream outlet 23a of the portion 21e1 (arrow α24a in FIG. 4).

  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.

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).

  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. It is discharged from the second upstream outlet 23b of the portion 21e2 (arrow α24b in FIG. 4).

<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, and the vertical axis shows the magnitude of current.
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.

  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.

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.

  Therefore, the heating times 202, 203, 204, 205, 206, and 207 are changed according to 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.

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.

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.

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 high in reliability.

<< 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.

  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.

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.

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.

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.

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.

  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.

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.

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.

However, as long as they are arranged so as to cross each other, they are not necessarily vertical.

  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. .
