Description

  The present invention relates to a separator, and more particularly to a separator that separates contaminants contained in a fluid using a cyclone.

  Conventional cyclonic separators only work in one direction, and a separate separator and switching device must be installed in the opposite direction. For this reason, it was necessary to have a forward direction flow path and a reverse direction flow path (for example, refer patent document 1).

  In addition, there is a thing that requires a reverse cleaning mechanism, a clogging removal device, and the like because the separated matter is clogged at the separated matter outlet (for example, see Patent Document 2).

Embodiment 1 FIG.
1 is a structural diagram of a cyclone section in a bidirectional separator according to Embodiment 1 of the present invention. FIG. 2 shows the forward flow of the fluid in Embodiment 1 of the present invention, and FIG. 3 shows the reverse flow. FIG. 4 is a modification of the configuration of FIG. 1 and shows a structure using a dedicated inlet / outlet connection port. 5 shows the forward flow of the fluid in the configuration of FIG. 4, and FIG. 6 shows the reverse flow of the configuration in FIG. In any of FIGS. 1 to 6, (a) is a horizontal sectional view, and (b) is an axial sectional view. In addition, although demonstrated as a fluid below, suppose that the fluid contains liquid and gas.

  As shown in FIGS. 1 to 3, the main body of the bidirectional separator according to the first embodiment is a shell 1 having a cylindrical shape or a substantially cylindrical shell shape, and has a cyclone function. This is a separator for generating a cyclone in the shell 1 and separating the contaminants mixed in the fluid from the fluid by a centrifugal separation method. In the present embodiment, the flow can be switched to a bidirectional flow, and the contaminants contained in the fluid can be separated in any of the bidirectional flows. As shown in FIG. 1, four cylindrical connection ports 2, 3, 4, 5 are provided so as to protrude in four directions from the outer peripheral surface of the shell 1 through the shell 1. . These bidirectional connection ports 2, 3, 4, and 5 all have the same shape, and are provided at point-symmetric positions as shown in FIG. It arrange | positions so that the direction connection port may become an angle of 90 degrees. That is, even if the shell 1 is rotated by 90 °, the same arrangement is obtained. Further, as shown in FIG. 1 (b), the bidirectional connection ports 2, 3, 4 and 5 are all at an angle of approximately 45 ° with respect to the axial direction of the shell 1 and upward. Is installed. The angle / straightness of the bidirectional connection ports 2, 3, 4, and 5 with respect to the shell 1 varies depending on the arrangement and separation performance. In addition, the arrangement of the bidirectional connection ports 2, 3, 4, and 5 is not limited to this case, and any arrangement other than this example may be used as long as all of them are oriented to generate cyclones in the same direction.

  As shown in FIG.1 (b), the downward direction of the shell 1 is carrying out cone shape (conical shape), and the lower end part (henceforth a cyclone termination | terminus part) is opened. A cylindrical or substantially cylindrical inner cylinder 6 is provided inside the cylindrical shell 1. Since the outer diameter of the inner cylinder 6 is smaller than the inner diameter of the shell 1, a space as shown in FIG. 1B is formed between the outer periphery of the inner cylinder 6 and the inner periphery of the shell 1 without contacting each other. ing. The lower part of the inner cylinder 6 has a cone shape (conical shape), and its lower end is opened and communicated with the cyclone end portion. Also, four holes are provided above the inner cylinder 6 and communicate with the inner ends of the bidirectional connection ports 2, 3, 4 and 5 through the connecting pipes 2A, 3A, 4A and 5A, respectively. Has been. The outer ends of the bidirectional connection ports 2, 3, 4, and 5 are open to the outside, and fluid serves as an entrance / exit. In addition, the cyclone end portion of the shell 1 is provided with a discharge port 7 for discharging separated contaminants. Note that the connecting pipes 2A, 3A, 4A, and 5A connected to the inner ends of the bidirectional connection ports 2, 3, 4, and 5 restrict the flow path as shown in FIG. (That is, the inner diameters of the connecting pipes 2A, 3A, 4A, and 5A are smaller than the inner diameters of the bidirectional connection ports 2, 3, 4, and 5).

  Next, the configuration of FIG. 4 will be described. 4 to 6, the inlet connection port 9, the outlet connection port 10, and the bidirectional connection port 4 are provided from the outer peripheral surface of the shell 1. As shown in FIG. 4A, the outlet connection port 10 and the bidirectional connection port 4 are provided in parallel so that the outer end faces in the same direction. The bidirectional connection port 4 and the inlet connection port 9 are provided at point-symmetric positions. Moreover, the upper end surface of the shell 1 is opened, and the outlet connection port 11 extends upward from the upper end surface. Inside the shell 1, as in the configuration of FIG. 1, an inner cylinder 6 communicating with the cyclone end portion and the connection ports 4, 9, 10, 11 is provided. Further, the cyclone end portion of the shell 1 is provided with a discharge port 7 for discharging the separated contaminants. The bidirectional connection port 4 and the inner cylinder 6 are connected via a communication pipe 4A. The communication pipe 4A portion of the bidirectional connection port 4 has a narrowed flow path. The flow path is also narrowed at the inner end portion of the inlet connection port 9. The outlet connection ports 10 and 11 are directly connected to the inner cylinder 6. The other configuration is the same as the configuration of FIG. 1, and thus description thereof is omitted here. The arrangement of the connection ports 4, 9, and 10 is not limited to this case, and any arrangement other than this example may be used as long as the direction of generating a cyclone in the same direction is generated even when the inlet and outlet of the fluid are switched. .

  The operation will be described. First, the operation in the configuration of FIG. 1 will be described. In the configuration of FIG. 1, the positive flow of the main fluid from the bidirectional connection ports 2 and 4 as the inlet to the bidirectional connection ports 3 and 5 as the outlet will be described. In FIG. 2 configured as described above, the fluids flowing in from the bidirectional connection ports 2 and 4 serving as the inlets are respectively connected pipes whose flow paths are narrowed from the inner ends of the bidirectional connection ports 2 and 4. Through 2A and 4A, it enters the space inside the shell 1 and outside the inner cylinder 6 to form a swirling flow in the same direction, and a cyclone effect is generated. As described above, when the connection ports 2 and 4 are used as the inlets, ejection occurs in the connecting pipes 2A and 4A, and suction from the inner cylinder 6 occurs (if the ejection is insufficient, It will be a blowout and some will be discharged directly from the inner cylinder 6). Thereby, the contaminant with large specific gravity can be isolate | separated from the fluid. The fluid from which the contaminants are separated flows into the inner cylinder 6 from the lower end of the inner cylinder 6, passes through the connecting pipes 3A and 5A, and is discharged to the outside from the outer ends of the bidirectional connection ports 3 and 5 serving as outlets. Is done. As described above, when the connection ports 3 and 5 are used as the outlet, the fluid pushed out from the inner cylinder 6 is discharged from the connecting pipe to the outlet. A part is ejected at the inner end and returns to the shell 1. On the other hand, the separated contaminants are discharged from the discharge port 7 to the outside. In addition, the separation state can be adjusted by selecting the position, length, and shape of the cyclone end portions of the shell 1 and the inner cylinder 6.

  In addition, the flow of the auxiliary fluid in the communication pipes 2A, 3A, 4A, and 5A in the configuration of FIG. 1 will be described. Since the flow (inflow) from the bidirectional connection ports 2 and 4 serving as the inlets is narrowed in the cross section (flow path) by the connecting pipes 2A and 4A, the flow velocity becomes faster and the pressure is lower than the surroundings. The fluid in the inner cylinder 6 is drawn out to form a circulating flow that is added to the swirling flow. Further, at the inner end portions of the bidirectional connection ports 3 and 5 serving as fluid outlets, the swirl flow from the connection ports 2 and 4 serving as the inlets results in a lower pressure than the surroundings, and from the connecting pipes 3A and 5A to the inner cylinder 6 The fluid inside is drawn out to form a circulating flow that is added to the swirling flow.

  Next, the reverse flow of the main fluid when the inlet and the outlet are switched in the configuration of FIG. 1 will be described. In FIG. 3, the fluid flowing in from the bidirectional connection ports 3, 5 serving as the inlet enters the space inside the shell 1 and outside the inner cylinder 6 from the inner ends of the bidirectional connection ports 3, 5, The swirl flow is in the same direction as before switching the outlet, and a cyclone effect occurs. As a result, the contaminants are separated, and the fluid from which the contaminants are separated flows into the inner cylinder 6 from the lower end of the inner cylinder 6, passes through the connecting pipes 2A and 4A, and is discharged to the outside from the connection ports 2 and 4 serving as outlets. Is done. Further, the separated contaminants are discharged to the outside from the discharge port 7.

  Next, the operation in the configuration of FIG. 4 will be described. In the configuration of FIG. 4, the forward flow of the main fluid from the inlet connection port 9 as the inlet and the bidirectional connection port 4 as the inlet to the outlet connection ports 10 and 11 as the outlet will be described. The inlet connection port 9 is not provided with a connecting pipe, and the bidirectional connecting port 4 has a flow path restricted at the connecting pipe 4A portion, and a side flow is generated at that portion. Since it is configured in this way, as shown in FIG. 5, the fluid flowing in from the inlet connection port 9 serving as the inlet flows from the inner ends of the inlet connection port 9 and the bidirectional connection port 4 to the inside of the shell 1. And it enters the space which is the exterior of the inner cylinder 6, becomes a swirl flow, and a cyclone effect occurs. Thereby, the contaminant with large specific gravity can be isolate | separated from the fluid. The fluid from which the contaminants are separated flows into the inner cylinder 6 from the lower end of the inner cylinder 6 and is discharged to the outside from the outer end portions of the connection ports 10 and 11 serving as outlets. On the other hand, the separated contaminants are discharged from the discharge port 7 to the outside. In addition, the separation state can be adjusted by selecting the position, length, and shape of the cyclone end portions of the shell 1 and the inner cylinder 6.

  Further, in the configuration of FIG. 4, the flow of the sub fluid in the communication pipe 4 </ b> A will be described. Since the flow (inflow) from the bidirectional connection port 4 serving as the inlet is narrowed in cross section (flow path) at the inner end, the flow velocity becomes faster and the pressure is lower than the surroundings, so the flow from the inner end of the bidirectional connection port 4 The fluid in the inner cylinder 6 is drawn out to form a circulating flow that is added to the swirling flow.

  Next, the reverse flow of the main fluid when the inlet and outlet of the bidirectional connection port 4 are switched in the configuration of FIG. 4 will be described. In FIG. 6, the fluid that has flowed in from the inlet connection port 9 and the bidirectional connection port 4 serving as the inlet is inside the shell 1 and outside the inner cylinder 6 from the inner ends of the inlet connection port 9 and the bidirectional connection port 4. A swirl flow in the same direction as before entering the space and switching between the entrance and the exit, and a cyclone effect occurs. As a result, the contaminants are separated, and the fluid from which the contaminants are separated flows into the inner cylinder 6 from the lower end of the inner cylinder 6 and is discharged to the outside through the connection ports 10 and 11 serving as outlets. Further, the separated contaminants are discharged to the outside from the discharge port 7.

  As described above, since the cyclone functions even when the direction of the fluid is reversed, the contaminants can be separated in any of the bidirectional flows. Until the flow rate and fluid resistance are balanced, the secondary fluid circulates internally, and both the circulation flow rate and the circulation speed increase, thereby improving the cyclone effect. Note that the discharge port 7 is not necessarily provided. When the discharge port 7 is not provided and the lower end of the shell 1 is not open, the separated contaminants are stored in the shell 1. Further, in the present embodiment, since the inner cylinder 6 is provided, it serves as a guide for the center of the cyclone, helps to form the cyclone, and can separate a portion with a large amount of foreign matter from the exhaust, thereby improving the separation efficiency. be able to. Note that the inner cylinder 6 is not necessarily provided, and operates in the same manner as in the present embodiment when the specific gravity difference between the fluid and the contaminant is large.

Embodiment 2. FIG.
In the first embodiment described above, the cyclone is set in a certain direction. In the second embodiment, a case where the cyclone direction is reversed or stirred will be described. FIG. 7 shows the structure of the cyclone section in such a case, FIG. 8 shows the forward flow of the fluid in Embodiment 2 of the present invention, and FIG. 9 shows the reverse flow. 7A to 9B, (a) is a horizontal sectional view and (b) is an axial sectional view.

  7 to 9, a bidirectional connection port 2 serving as an entrance from the outer peripheral surface of the shell 1 and a bidirectional connection port 3 serving as an exit are provided, and a cyclone end portion and a bidirectional connection port 2 are provided inside the shell 1. 3 is provided. The cyclone end of the shell 1 is provided with a discharge port 7 for separated contaminants. The bidirectional connection ports 2 and 3 and the inner cylinder 6 are connected by connecting pipes 2A and 3A. The communication pipes 2A and 3A of the bidirectional connection ports 2 and 3 are narrowed in the flow path. In the present embodiment, as shown in FIG. 7 (a), the bidirectional connection ports 2 and 3 are provided in parallel and opposite to each other with the inner cylinder 6 in between at a line-symmetrical position, The outer ends of the bidirectional connection ports 2 and 3 are directed in the same direction.

  The operation will be described. The flow of the main fluid in the positive direction from the bidirectional connection port 2 serving as the inlet to the bidirectional connection port 3 serving as the outlet will be described. In FIG. 8 configured in this way, the fluid flowing in from the bidirectional connection port 2 serving as the inlet enters the space inside the shell 1 and outside the inner cylinder 6 from the inner end of the bidirectional connection port 2, It becomes a swirl flow. Thus, the contaminants are separated, and the fluid from which the contaminants are separated flows into the inner cylinder 6, passes through the connecting pipe 3A, and is discharged to the outside from the bidirectional connection port 3 serving as an outlet. On the other hand, the separated contaminants are discharged from the discharge port 7.

  Next, the flow in the reverse direction of the main fluid when the inlet and outlet of the bidirectional connection ports 2 and 3 are switched will be described. In the present embodiment, since the bidirectional connection ports 2 and 3 are provided in line-symmetric positions, the fluid flowing from the bidirectional connection port 3 serving as an inlet in FIG. It enters the space inside the shell 1 and outside the inner cylinder 6 from the part, and the swirl flow is in the opposite direction to that before switching the inlet and outlet. Thus, the contaminants are separated, and the fluid from which the contaminants are separated flows into the inner cylinder 6, passes through the communication pipe 2A, and is discharged from the bidirectional connection port 2 serving as an outlet. The separated contaminants are discharged from the discharge port 7. At this time, in the forward flow shown in FIG. 8, it is assumed that the separated mixture is deposited at the end of the cyclone and becomes a deposit as shown in FIG. 8B. In this embodiment, in the flow in the reverse direction of FIG. 9, a swirl flow in the opposite direction to that before switching between the inlet and the outlet is formed. Therefore, as shown in FIG. Since the fluid collides and peels off the deposit from the inner wall of the shell 1, the deposit is discharged from the discharge port 7 to the outside.

  As described above, in the present embodiment, the fluid direction changes and the flow is disturbed at the time of switching between the inlet and the outlet, so that a reverse force is applied to the contaminants stably accumulated at the end of the cyclone, The contaminants deposited by the impact move to the discharge port 7. By removing the accumulated contaminants, a stable swirl flow is obtained thereafter.

Embodiment 3 FIG.
In the above-described first and second embodiments, the shell 1, the bidirectional connection ports 2, 3, 4, and 5, the inner cylinder 6, the inlet connection port 9, and the outlet connection ports 10 and 11 have an integral structure, or , The connection ports 2, 3, 4, 5, the inlet connection port 9, the outlet connection ports 10, 11 and the inner cylinder 6 need to be sealed, but in the third embodiment, the connection ports 3, 4, 9, An embodiment in which a gap can be provided between the inner cylinder 6 and the inner cylinder 6 so as to be indirectly linked to each other to enable the amount of internal circulation to be positively increased with a structure that can be separately manufactured will be described. In the present embodiment, as shown in FIG. 10B, the positions of the connection ports 3, 4, 9, and 10 are shifted downward by the gap as compared with the configuration of FIG. Further, in the present embodiment, a guide for mainly guiding the flow direction and adjusting the opening dimension and the clearance dimension on the inner cylinder side and the connection port side is provided, and this guide allows the flow from this portion to the connection port. Whether the fluid to be used is the outer periphery of the inner cylinder or the inner cylinder is adjusted. This adjustment is performed at the design stage, and the guide is fixed by the adjustment. As shown in FIG. 10A, the inlet connection port 9 and the inner cylinder 6 are not in direct communication with each other and are provided apart from each other. The inner end portion of the outlet connection port 10 is closed or shortened or changed in direction, and connected to the inner cylinder 6 via the connecting pipe 10A and the guide 10B. Here, the closed short circuit is a case where there is no gap. In this case, since the opening of the inner end portion of the outlet connection port 10 communicates directly with the inner cylinder 6, the state is referred to as a closed short circuit. I will call it.

  FIG. 10 shows the structure of the cyclone section in such a case, FIG. 11 shows the forward flow of the fluid in Embodiment 3 of the present invention, and FIG. 12 shows the reverse flow. 10A to 12B, (a) is a horizontal sectional view, and (b) is an axial sectional view. 10 to 12, from the outer peripheral surface of the shell 1 to the inlet connection port 9, the bidirectional connection port 4 serving as the inlet, the bidirectional connection port 3 serving as the outlet, the outlet connection port 10, and the outlet connection port from the upper end surface of the inner cylinder 6. 11 is provided on the inner surface of the shell 1, and an inner cylinder 6 is provided in communication with the cyclone end portion, the bidirectional connection ports 3 and 4, and the outlet connection ports 10 and 11. The cyclone end of the shell 1 is provided with a discharge port 7 for separated contaminants. The inner cylinder 6 is provided with connecting pipes 3A, 4A and 10A, and the bidirectional connection ports 3 and 4 and the outlet connection port 10 are provided with guides 3B, 4B and 10B. With the guides 3B, 4B, and 10B, it is possible to adjust whether the fluid flowing into the connection port is the outer periphery of the inner cylinder 6 or the inner cylinder 6. The inner cylinder 6 is attached to the shell 1 via a gasket 8 as shown in FIG. The outlet connection port 11 is directly attached to the inner cylinder 6. FIG. 27 shows a detailed enlarged view. As shown in FIG. 27, the gasket 8 is interposed by a gap between the connection ports 3, 4, 9, 10 formed in the shell 1 and the inner cylinder 6, and is fixed by a stud bolt, a nut, a washer or the like. Has been. This is called a stud seat shape. A modified flange seat shape is shown in FIG. In the case of FIG. 28, it is fixed from above and below with bolts and nuts using washers. In FIG. 27 and FIG. 28, for the sake of clarity, the gasket 8 is illustrated with a gap above and below the gasket 8, but in practice, the stud bolt or bolt is tightened until the gap between the gasket 8 is eliminated. It is firmly fixed. Further, the inner cylinder 6 can be integrated with the shell 1. In addition, although it is set as the gasket 8 in FIG. 10, it is not restricted to this case, In a small thing, it can be set as a screw type (refer FIG. 29), an O-ring one stop ring type (refer FIG. 30), etc.

  In the present embodiment, as shown in FIG. 10A, four connection ports 3, 4, 9, and 10 are provided so as to protrude in four directions from the outer peripheral surface of the shell 1. As shown in FIG. 10A, these connection ports 3, 4, 9, and 10 are arranged such that adjacent connection ports are at an angle of 90 °. Further, as shown in FIG. 10B, the connection ports 3, 4, 9, and 10 are all installed at an angle of approximately 45 ° with respect to the axial direction of the shell 1 and upward. Has been.

  Next, the flow in the connecting pipes 3A, 4A, 10A and the guides 3B, 4B, 10B will be described with reference to FIG. The flow that flows in from the inlet connection port 9 becomes a swirling flow. Further, the flow that flows in from the bidirectional connection port 4 serving as an inlet becomes a low pressure from the surroundings by the guide 4B, and the fluid in the inner cylinder 6 is drawn out from the outer peripheral surface of the inner cylinder 6 through the connecting pipe 4A. To form a circulating flow. At the inner end of the bidirectional connecting port 3 serving as the outlet, the swirl flow from the bidirectional connecting port 4 serving as the inlet causes the pressure to be lower than the surroundings, and at the same time the fluid in the inner cylinder 6 is drawn from the guide 3B through the connecting pipe 3A. A fluid is also drawn from the outer peripheral surface to form a circulating flow that is added to the swirling flow. At this time, a part of the fluid flowing from the outer peripheral surface of the inner cylinder 6 is mixed into the mainstream and discharged from the connection port 3. At the outlet connection port 10, the fluid that flows in is mainly ejected from the inner cylinder 6 and discharged from the outer end thereof. At this time, the fluid in the shell is sucked out or ejected from the gap depending on the position, size, and shape of the guide 10B and the connecting pipe 10A. At the outlet connection port 11, the fluid with the least foreign matter in the system ejected from the inner cylinder 6 is discharged. FIG. 12 shows a case where the entrance and exit of the bidirectional connection port are reversed.

  As described above, when the inner cylinder 6 can be separated, manufacturing and assembly of the shell 1, the inlet connection port 9, the bidirectional connection ports 3 and 4, and the outlet connection port 10 can be facilitated. Further, the amount of fluid drawn can be adjusted by the positional relationship, size, shape, etc. of the guides 3B, 4B, 10B and the connecting pipes 3A, 4A, 10A.

Embodiment 4 FIG.
In the first, second, and third embodiments described above, the inner cylinder 6 is required. However, in the fourth embodiment, a case where the contaminants can be easily separated by a cyclone that does not use the inner cylinder is shown. . FIG. 13 shows the structure of the cyclone section in such a case, FIG. 14 shows the forward flow of the fluid in Embodiment 4 of the present invention, and FIG. 15 shows the reverse flow. Moreover, the structure in the case of not providing a discharge port in FIGS. 16-18 is shown. Further, FIGS. 19 to 21 show a structure when no guide is provided. In any of FIGS. 13 to 21, (a) is a horizontal cross-sectional view, and (b) is an axial cross-sectional view. 13 to 21, bidirectional connection ports 2 and 4 that serve as inlets from the outer peripheral surface of the shell 1 and bidirectional connection ports 3 and 5 that serve as outlets are provided. These bidirectional connection ports 2, 3, 4 and 5 are provided with guides 2B, 3B, 4B and 5B. These bidirectional connection ports 2, 3, 4, and 5 are arranged so that adjacent bidirectional connection ports are at an angle of 90 ° as shown in FIGS. 13 (a) to 21 (a). , Are arranged at point-symmetric positions. Further, as shown in FIGS. 13B to 21B, the bidirectional connection ports 2, 3, 4, and 5 all have the same shape and are substantially in the axial direction of the shell 1. They are installed at an angle of 45 ° and upward. Note that the arrangement of the bidirectional connection ports 2, 3, 4, and 5 is not limited to this case, and any arrangement other than this example may be used as long as all of them are oriented to generate cyclones in the same direction. Moreover, in the example of FIGS. 13-15 and FIGS. 19-21, the discharge port 7 of the separated material is provided in the cyclone termination | terminus part of the shell 1. FIG. Other configurations are the same as those in the above-described embodiment, and thus description thereof is omitted here.

  Next, in FIGS. 13 to 15 configured as described above, as shown in FIG. 14, the flow from the bidirectional connection ports 2 and 4 serving as the inlet becomes a swirl flow in the shell 1 to separate contaminants. The fluid from which the contaminants are separated passes through the cyclone vortex core, flows into the bidirectional connection ports 3 and 5 from the guides 3B and 5B, and is discharged to the outside. At the guides 2B and 4B of the bidirectional connection ports 2 and 4 serving as the inlets, the pressure becomes lower than the surroundings and the circulating flow is drawn out. Further, the inner ends of the bidirectional connection ports 3 and 5 serving as outlets are also at a lower pressure than the surroundings, and draw a circulating flow from the guides 3B and 5B. At this time, since there is no cooperation by the inner cylinder, a part of the fluid flowing in from the bidirectional connection ports 2 and 4 serving as the inlets flows from the inner ends of the bidirectional connection ports 2 and 4 and the guides 2B and 4B to the bidirectional connection port 2. , 4 are discharged. Double flow occurs at the inner ends of the bidirectional connection ports 2 and 4. The contaminants separated from the fluid are discharged to the outside from the discharge port 7.

  Since the operations in the configuration shown in FIGS. 16 to 18 are the same, the description thereof is omitted here. However, in the example of FIGS. 16 to 18, the bottom of the shell 1 is closed and the discharge port 7 is not provided, so that contaminants separated from the fluid accumulate on the bottom of the shell 1. In order to make it possible to take out the accumulated contaminants, in this case, the bottoms of the connection ports 2, 3, 4, 5 or the shell 1 are fixed with screws or flanges so that the structure can be disassembled. desirable.

  On the other hand, when there is no guide 3B, 5B of FIGS. 19-21, it enters from the inner end of the bidirectional connection ports 3 and 5 and is discharged. In FIG. 21, the flow from the connection ports 3 and 5 as the inlet becomes a swirl flow in the shell 1 to separate the contaminants, and the fluid from which the contaminants are separated passes through the cyclone vortex core and is connected from the guides 2B and 4B. It flows into the mouths 2 and 4 and is discharged. At the guides 3B and 5B of the bidirectional connection ports 3 and 5 serving as the inlets, the pressure is lower than the surroundings, and the circulating flow is drawn out.
