Description

The present invention relates to a gas-liquid separation device.

2. Description of the Related Art Conventionally, there is known a gas-liquid separation device that separates a gas-liquid mixed fluid in which gas and liquid are mixed into gas and liquid. A general gas-liquid separation device is equipped with a container configured to generate a swirling flow by using the flow of an inflowing gas-liquid mixed fluid, and in this container, centrifugal force is used to generate a gas-liquid mixture. The mixed fluid is separated into gas and liquid. In this case, the liquid (droplets) in the gas-liquid mixed fluid is separated from the gas flow by the centrifugal force, falls under the influence of gravity, and is stored in the liquid storage section provided at the bottom of the container. To be done. The liquid level of the liquid stored in the liquid storage unit is measured, and the discharge of the liquid from the liquid storage unit is controlled based on the measured liquid level. In this way, the amount of liquid stored in the liquid storage section is appropriately maintained.

However, since the liquid level of the liquid stored in the liquid storage section is affected by the flow of gas swirling above the liquid level, the liquid level fluctuates. When the flow velocity of the gas-liquid mixed fluid flowing into the container increases, the liquid level fluctuates significantly, and the liquid may be rolled up. The rolled-up liquid entrains in the gas, and there is a problem that the entrained amount of the liquid entrained in the gas discharged from the container increases. An increase in the amount of liquid entrained may affect the equipment provided downstream of the gas-liquid separation device. For example, when the compressor is connected to the downstream side of the gas-liquid separator, the liquid may adhere to the impeller inside the compressor to cause erosion.

Further, when the liquid level of the liquid in the liquid storage portion is fluctuating, the liquid level decreases near the center and rises near the peripheral edge (near the wall surface of the container). If the liquid level fluctuates in this way, it becomes difficult to measure the liquid level of the liquid stored in the liquid storage section with high accuracy. In particular, when the flow velocity of the gas-liquid mixed fluid flowing into the container increases, the fluctuation of the liquid level may increase. For example, when the flow velocity of the gas-liquid mixed fluid changes transiently, it becomes difficult to measure the liquid level. In this case, it becomes difficult to discharge the liquid from the liquid storage section based on the liquid level, and the liquid storage amount may increase. Then, when the flow rate of the gas-liquid mixed fluid is high in a state where the amount of stored liquid is excessively large, the amount of liquid entrained in the gas discharged from the container may also increase.

The present invention has been made in consideration of such a point, and an object of the present invention is to provide a gas-liquid separation device capable of suppressing fluctuations in the liquid level of a stored liquid.

A gas-liquid separation device according to an embodiment includes a gas-liquid separation unit that separates a gas-liquid mixture into a gas and a liquid while swirling a gas-liquid mixed fluid, and a liquid storage that is provided below the gas-liquid separation unit and stores the separated liquid. And a container having a part. A partition member having a partition opening that communicates the gas-liquid separation unit and the liquid storage unit is interposed between the gas-liquid separation unit and the liquid storage unit. A lid is provided above the partition opening of the partition member.

A gas-liquid separation device according to another embodiment is provided below the gas-liquid separation part, which separates the gas-liquid mixed fluid into gas and liquid while swirling the gas-liquid mixed fluid, and stores the separated liquid. And a container having a liquid storage part. A partition member having a partition opening that communicates the gas-liquid separation unit and the liquid storage unit is interposed between the gas-liquid separation unit and the liquid storage unit. A swirl prevention member that prevents swirling motion of the stored liquid is provided in the liquid storage portion.

According to the present invention, it is possible to prevent the liquid level of the stored liquid from changing.

Hereinafter, a gas-liquid separation device according to an embodiment of the present invention will be described with reference to the drawings.

(First embodiment)
First, the gas-liquid separation device according to the first embodiment of the present invention will be described with reference to FIGS. The gas-liquid separation device according to the present embodiment is a device for separating a gas-liquid mixed fluid in which gas and liquid are mixed into gas and liquid.

Here, a gas compression system to which the gas-liquid separation device according to the present embodiment is applied will be described with reference to FIG. This gas compression system is a system for supplying compressed gas to turbine equipment and boiler equipment. The gas may be air.

The gas compression system 100 shown in FIG. 1 separates a liquid from the gas discharged from the gas storage tank 102 and the gas 101 which stores the compressor 101 which compresses gas, the gas compressed by the compressor 101. The gas-liquid separator 1 (also called an air dehumidifier) is provided. Since the gas stored in the gas storage tank 102 is accompanied (or contains) a liquid, the gas-liquid separation device 1 is provided to remove the liquid from the gas. In the gas-liquid separator 1, the liquid is removed from the gas and the gas is dehumidified. The dehumidified gas is supplied to the turbine equipment 103 and the boiler equipment 104 and used for various purposes.

The configuration of the gas compression system 100 is not limited to the configuration shown in FIG. 1 and is arbitrary. Further, the gas-liquid separation device 1 according to this embodiment can be applied to a system for any purpose.

Next, the gas-liquid separation device 1 according to this embodiment will be described in more detail.

As shown in FIG. 2, the gas-liquid separation device 1 according to the present embodiment includes a container 10, a partition plate 20 (partitioning member) provided in the container 10, and a cover plate 30 provided in the container 10 ( Lid), and.

The container 10 extends vertically in a cylindrical shape from the bottom surface to the ceiling surface, and is generally formed in a cylindrical shape. Further, the container 10 has a gas-liquid separation chamber 11 (gas-liquid separation unit) and a liquid storage unit 12 provided below the gas-liquid separation chamber 11. The gas-liquid separation chamber 11 is a part that separates the gas-liquid mixture while swirling the gas-liquid mixed fluid. The liquid storage portion 12 is a portion that stores the liquid separated from the gas, and is provided in the lower portion of the container 10. Here, the gas may be air and the liquid may be water.

The container 10 has a fluid inlet 13 into which the gas-liquid mixed fluid flows, a gas outlet 14 from which a gas (dry gas) separated from the gas-liquid mixed fluid flows out, and a liquid separated from the gas-liquid mixed liquid flows out. And a liquid outlet 15. The fluid inlet 13 is arranged in the lower part of the gas-liquid separation chamber 11, and the gas outlet 14 is arranged in the upper part of the gas-liquid separation chamber 11 (the upper part of the container 10). The liquid outlet 15 is arranged in the lower part of the liquid storage part 12 (the lower part of the container 10). Although not shown, the fluid inlet 13 may be arranged so as to be eccentric to one side with respect to the center of the container 10 in the direction orthogonal to the inflow direction when viewed from above. In this case, the gas-liquid mixed fluid can flow from the fluid inlet 13 along the wall surface of the container 10, and a swirl flow can be easily formed in the gas-liquid separation chamber 11. Alternatively, a guide member (not shown) for guiding the inflowing gas-liquid mixed fluid in the direction along the wall surface of the container 10 may be provided in the container 10 near the fluid inlet 13. Even in this case, the gas-liquid mixed fluid can be made to flow along the wall surface of the container 10 in the gas-liquid separation chamber 11, and a swirling flow can be easily formed in the gas-liquid separation chamber 11.

The partition plate 20 is interposed between the gas-liquid separation chamber 11 and the liquid storage portion 12, and partitions the gas-liquid separation chamber 11 and the liquid storage portion 12. That is, the partition plate 20 defines the gas-liquid separation chamber 11 and the liquid storage section 12. The partition plate 20 is arranged at a desired height position, and is arranged below the fluid inlet 13. As a result, the gas-liquid mixed fluid flowing from the fluid inlet 13 is supplied to the gas-liquid separation chamber 11. The outer peripheral edge portion of the partition plate 20 may be fixed to the wall surface of the container 10 by, for example, welding.

The partition plate 20 has a partition opening portion 21 that connects the gas-liquid separation chamber 11 and the liquid storage portion 12 to each other. As shown in FIG. 3, the partition opening 21 is arranged in the center of the partition plate 20 and is formed in a circular shape when viewed from above. Further, as shown in FIG. 2, the partition plate 20 is inclined so as to be positioned downward toward the partition opening 21. In other words, the partition plate 20 is inclined so as to be located upward toward the outer peripheral edge portion, and is formed in an inverted truncated cone shape.

As shown in FIG. 2, the cover plate 30 is provided above the partition opening portion 21 of the partition plate 20, and covers the partition opening portion 21 from above. The cover plate 30 is separated from the partition plate 20, and a space through which the liquid separated in the gas-liquid separation chamber 11 can pass is formed between the cover plate 30 and the partition plate 20.

In the present embodiment, lid plate 30 is inclined so as to be positioned downward toward the outer peripheral edge portion. In other words, the lid plate 30 may be formed in a conical shape that is inclined so as to be located upward toward the center and is convex upward. The lid plate 30 may be formed in a circular shape when viewed from above. The cover plate 30 may be formed concentrically with the partition opening 21. The outer diameter of the cover plate 30 is smaller than the outer diameter of the partition plate 20, but may be larger than the diameter of the partition opening 21. That is, when viewed from above, the lid plate 30 is formed so as to extend outside the partition opening portion 21, and the partition opening portion 21 may be entirely covered with the lid plate 30.

As shown in FIG. 3, the lid plate 30 may have a through hole 31 penetrating the lid plate 30. The through hole 31 causes the liquid on the upper surface of the cover plate 30 to drop from the cover plate 30. Plural such through holes 31 may be provided in the cover plate 30. Further, the through hole 31 may be entirely formed in the cover plate 30.

As shown in FIGS. 3 and 4, the lid plate 30 may include at least one of the hanging ear 32 and the handle 33. In FIGS. 3 and 4, an example in which the lid plate 30 has both the hanging ear 32 and the handle 33 is shown.

The hanging ear 32 is, for example, a member for hanging the lid plate 30 via a chain on a crane when carrying the container 10 into the container 10. FIG. 3 shows an example in which the two hanging ears 32 are formed so as to extend outward from the outer peripheral edge portion of the lid plate 30, but the number and arrangement of the hanging ears 32 are arbitrary.

The handle 33 is a member that allows an operator to grip the cover plate 30 when moving the cover plate 30. The handle 33 can be suitably used when attaching the lid plate 30 in the container 10 or when removing the lid plate 30. For example, as shown in FIG. 4, the handle 33 is formed so as to stand upright from the center of the upper surface of the lid plate 30. In the examples shown in FIGS. 3 and 4, two grips 33 are fixed to the cover plate 30, but the number and arrangement of the grips 33 are arbitrary.

As shown in FIGS. 2 to 4, the lid plate 30 is supported by the legs 40. The leg 40 extends upward from the partition plate 20. That is, the lower ends of the legs 40 are attached to the upper surface of the partition plate 20, and the upper ends of the legs 40 are attached to the lower surface of the lid plate 30. For example, the leg 40 may be fixed to the partition plate 20 and the cover plate 30 by welding. In the present embodiment, the cover plate 30 is supported by the plurality of legs 40. As shown in FIG. 3, the plurality of legs 40 may be arranged on the outer peripheral edge of the cover plate 30 and may be arranged concentrically with the cover plate 30 and the partition opening 21.

As shown in FIGS. 3 and 4, the leg 40 may be formed so as to extend vertically in a cylindrical shape. For example, the leg 40 may be formed in a solid shape, or may be formed in a hollow shape and formed in a cylindrical shape as a whole. The legs 40 adjacent to each other are separated from each other, and a space through which the liquid separated in the gas-liquid separation chamber 11 can pass is formed between the legs 40 adjacent to each other.

As shown in FIG. 5, the leg 40 may be reinforced by a reinforcing rib 50 (reinforcing member). A plurality of reinforcing ribs 50 may be provided around the fixing point between the lower end of the leg 40 and the upper surface of the partition plate 20. The reinforcing ribs 50 may be fixed to the legs 40 and the partition plate 20 by welding. Similarly, a plurality of the reinforcing ribs 50 may be provided around the fixing point between the upper end of the leg 40 and the lower surface of the lid plate 30, or may be fixed to the leg 40 and the lid plate 30 by welding. ..

As shown in FIG. 2, the container 10 of the gas-liquid separation device 1 is provided with a liquid level meter 60. That is, the liquid outlet 15 and the gas-liquid separation chamber 11 described above are connected by the measurement line 61. A liquid level meter 60 is provided on the measurement line 61. The measurement line 61 has a portion that extends in the vertical direction, and at this portion, a part of the liquid stored in the liquid storage portion enters to the same height as the liquid storage portion 12. Therefore, by measuring the liquid level of the liquid in the measurement line 61, the liquid level of the liquid storage section 12 can be obtained. If the liquid can enter the measurement line 61 to the same height as the liquid surface level of the liquid storage unit 12, the measurement line 61 is not the liquid outlet 15 but the lower part of the liquid storage unit 12 and the liquid discharge line 70 (open/close described later). The liquid outlet 15 may be connected to the valve 71).

A liquid discharge line 70 (drain line) is connected to the liquid outlet 15 of the gas-liquid separator 1 configured as described above. The liquid discharge line 70 is provided with an opening/closing valve 71 capable of switching between an open state and a closed state. The opening/closing valve 71 is a valve for permitting or blocking the discharge of the liquid from the liquid storage section 12 by the liquid discharge line 70. That is, the open/close valve 71 permits the discharge of the liquid from the liquid storage portion 12 in the open state, and shuts off the discharge of the liquid from the liquid storage portion 12 in the closed state.

As shown in FIG. 2, the opening/closing valve 71 may be controlled by the controller 80. In this case, an electric signal corresponding to the liquid level measured by the liquid level meter 60 is transmitted to the control device 80, and the controller 80 obtains the liquid signal measured by the liquid level meter 60 from the electric signal. The on-off valve 71 is controlled based on the surface level. For example, when the liquid level is equal to or higher than a predetermined upper limit reference value, the on-off valve 71 is opened to discharge the liquid stored in the liquid storage unit 12, and when the liquid level is equal to or lower than the predetermined lower limit reference value. Alternatively, the on-off valve 71 may be closed to stop the liquid discharge. The open/close valve 71 is not limited to being controlled by the control device 80, and may be switched by a manual operation by an operator.

Next, the operation of the present embodiment having such a configuration will be described.

When the gas-liquid mixed fluid in which gas and liquid are mixed flows into the fluid inlet 13 of the container 10 of the gas-liquid separation device 1, it swirls in the gas-liquid separation chamber 11. Here, the liquid mixed in the gas-liquid mixed fluid is entrained in the gas in the form of droplets or mist for various reasons. For example, when a cooling device is provided on the upstream side of the gas-liquid separator 1 and the gas-liquid mixed fluid is cooled in advance, the liquid is entrained in the gas in the state of droplets or mist generated by condensation. ing. However, the gas-liquid separation device 1 according to the present embodiment is not limited to being provided on the downstream side of the cooling device.

While the gas-liquid mixed fluid is swirling in the gas-liquid separation chamber 11, a part of the liquid in the gas-liquid mixed fluid receives centrifugal force and is separated from the gas flow to reach the wall surface of the container. The liquid that has reached the wall surface of the container is affected by gravity and descends along the wall surface of the container and reaches the partition plate 20. Further, even liquid that does not reach the wall surface of the container falls under the influence of gravity and reaches the partition plate 20 and the lid plate 30. The liquid that has reached the partition plate 20 flows toward the partition opening 21 on the upper surface of the partition plate 20. The liquid that has reached the lid plate 30 flows on the upper surface of the lid plate 30 toward the outer peripheral edge portion of the lid plate 30 and drops from the outer peripheral edge portion. A part of the liquid (reference numeral L shown in FIG. 3) reaching the lid plate 30 also descends from the through hole 31 provided in the lid plate 30. The liquid that has dropped from the outer peripheral edge portion of the lid plate 30 or the through hole 31 reaches the partition plate 20 and flows on the upper surface of the partition plate 20 toward the partition opening portion 21.

The liquid toward the partition opening 21 reaches the partition opening 21 through the space between the legs 40 adjacent to each other. The liquid that has reached the partition opening portion 21 descends from the partition opening portion 21 and is stored in the liquid storage portion 12.

When the liquid level of the liquid stored in the liquid storage unit 12 becomes equal to or higher than a predetermined upper limit reference value, the opening/closing valve 71 provided in the liquid discharge line 70 opens and the liquid stored in the liquid storage unit 12 is discharged. .. On the other hand, when the liquid level of the liquid stored in the liquid storage unit 12 becomes equal to or lower than the predetermined lower limit reference value, the opening/closing valve 71 is closed and the discharge of the liquid from the liquid storage unit 12 is stopped. In this way, the liquid level of the liquid stored in the liquid storage section 12 is maintained within the desired range.

By the way, in the gas-liquid separation chamber 11, the gas-liquid mixed fluid forms a swirling flow, but the liquid storage section 12 is partitioned from the gas-liquid separation chamber 11 by the partition plate 20. As a result, the influence of the swirling flow on the liquid storage portion 12 is suppressed, and the liquid level of the liquid stored in the liquid storage portion 12 is suppressed from changing.

In the present embodiment, lid plate 30 is provided above partition opening 21 of partition plate 20. As a result, the influence of the swirling flow in the gas-liquid separation chamber 11 on the partition opening 21 is suppressed. Therefore, the swirl flow is prevented from being formed in the partition opening 21, and the influence of the swirl flow in the gas-liquid separation chamber 11 on the liquid storage portion 12 is further suppressed. Therefore, the swirling flow is suppressed from being formed in the gas existing in the liquid storage section 12 (the space below the partition plate 20). In this case, the liquid level of the liquid stored in the liquid storage section 12 can be suppressed from varying and the liquid level can be stabilized. Therefore, it is possible to suppress the liquid from being rolled up from the liquid storage unit 12, and it is possible to reduce the amount of the liquid entrained in the gas discharged from the gas outlet 14 of the gas-liquid separator 1.

As described above, according to the present embodiment, the cover plate 30 is provided above the partition opening 21 of the partition plate 20 interposed between the gas-liquid separation chamber 11 and the liquid storage unit 12. This can suppress the formation of a swirl flow in the partition opening 21. Therefore, it is possible to prevent the liquid level of the liquid stored in the liquid storage unit 12 from changing. In this case, it is possible to prevent the liquid stored in the liquid storage unit 12 from being rolled up, and to reduce the amount of the liquid entrained in the gas discharged from the container 10. Further, since the fluctuation of the liquid level of the liquid stored in the liquid storage section 12 can be suppressed, the liquid level can be stabilized. Therefore, it is possible to facilitate the measurement of the liquid level and improve the measurement accuracy. As a result, it is possible to appropriately discharge the liquid from the liquid storage portion 12 based on the liquid surface level, and it is possible to maintain the liquid storage amount within a desired range. Also in this respect, it is possible to prevent the liquid stored in the liquid storage unit 12 from being rolled up and the amount of the liquid entrained in the gas discharged from the container 10 from increasing. That is, when the stored amount of the liquid is excessively large, the stored liquid tends to be easily rolled up, but by appropriately maintaining the stored amount of the liquid, the liquid is rolled up due to the increase of the stored amount. Can be suppressed. For example, when a compressor is connected to the gas outlet 14 of the gas-liquid separator 1, the amount of liquid entrained in the gas flowing into the compressor can be reduced, and erosion is generated in the impeller of the compressor. It can be suppressed from occurring.

Further, according to the present embodiment, the cover plate 30 is separated from the partition plate 20. As a result, a space through which the liquid separated in the gas-liquid separation chamber 11 can pass can be formed between the cover plate 30 and the partition plate 20. Therefore, the liquid can be made to flow to the liquid storage portion 12 through the partition opening portion 21 and can be stored in the liquid storage portion 12.

Further, according to the present embodiment, the leg 40 extending upward from the partition plate 20 supports the lid plate 30. Thus, the partition plate 20 is stably supported by the partition plate 20 while forming a space between the partition plate 20 and the cover plate 30 through which the liquid separated in the gas-liquid separation chamber 11 can pass. You can

Further, according to the present embodiment, the leg 40 is reinforced by the reinforcing rib 50. As a result, the support strength of the cover plate 30 can be improved. Therefore, even when the flow velocity of the gas-liquid mixed fluid flowing into the gas-liquid separation chamber 11 changes transiently, the lid plate 30 can be stably supported.

Further, according to the present embodiment, the cover plate 30 is supported by the plurality of legs 40. As a result, the support of the cover plate 30 can be stabilized.

Further, according to the present embodiment, the leg 40 is welded to the partition plate 20 and the lid plate 30. Thereby, the leg 40 can be firmly fixed to the partition plate 20 and the lid plate 30, and the support of the lid plate 30 can be stabilized. Further, since it is possible to fix the legs 40 and the partition plate 20 at the fixing points and the leg 40 and the cover plate 30 at the fixing points without using bolts or the like, it is possible to prevent corrosion deterioration.

Further, according to the present embodiment, lid plate 30 is inclined so as to be positioned downward toward the outer peripheral edge portion. As a result, the liquid that has dropped onto the upper surface of the lid plate 30 can quickly flow toward the outer peripheral edge portion, and it is possible to prevent the liquid from remaining on the upper surface of the lid plate 30. Therefore, the liquid that has reached the upper surface of the lid plate 30 can be quickly dropped from the lid plate 30, and the liquid can be prevented from being rolled up on the upper surface of the lid plate 30.

Further, according to the present embodiment, the cover plate 30 has the through hole 31 penetrating the cover plate 30. As a result, the liquid that has dropped onto the upper surface of the lid plate 30 can drop from the lid plate 30 through the through holes 31, and it is possible to prevent the liquid from remaining on the upper surface of the lid plate 30. Therefore, the liquid that has reached the upper surface of the lid plate 30 can be quickly dropped from the lid plate 30, and the liquid can be prevented from being rolled up on the upper surface of the lid plate 30.

Further, according to the present embodiment, lid plate 30 has at least one of hanging ear 32 and handle 33. When the hanging ear 32 is provided, the carrying operation of the lid plate 30 into the container 10 can be facilitated by using the hanging ear 32. When the cover 33 is provided, the lid plate 30 can be easily gripped, and workability at the time of attaching or removing the lid plate 30 can be improved.

Further, according to the present embodiment, the partition plate 20 is inclined so as to be positioned downward toward the partition opening 21. As a result, the liquid that has dropped onto the upper surface of the partition plate 20 can quickly flow toward the partition opening portion 21, and it is possible to prevent the liquid from remaining on the upper surface of the partition plate 20. Therefore, the liquid that has reached the upper surface of the partition plate 20 can be quickly dropped from the partition plate 20, and it is possible to prevent the liquid from being rolled up on the upper surface of the partition plate 20.

In addition, in the above-described present embodiment, the example in which the leg 40 extends in the vertical direction in a cylindrical shape has been described. However, the present invention is not limited to this, and the leg 40 may be formed in a radial shape or a spiral shape when viewed from above. This can further prevent the flow of the liquid around the leg 40 toward the partition opening 21 from being obstructed. Note that the legs 40 are formed radially so that the legs 40 are formed so as to extend in the radial direction with respect to the center of the partition opening 21 (the center of the container 10) when viewed from above. Means Further, the leg 40 is formed in a spiral shape when the leg 40 is viewed from above, the leg 40 is a gas-liquid mixture in the gas-liquid separation chamber 11 with respect to the center of the partition opening 21 (the center of the container 10). It means that it is formed in a spiral shape along the swirling flow of the fluid. In this case, it is possible to prevent the leg 40 from interfering with the swirling flow of the gas. Therefore, it is possible to prevent the swirling flow in the gas-liquid separation chamber 11 from being weakened more than necessary, and improve the efficiency of separating the liquid from the gas. In addition, the flow of the liquid toward the partition opening 21 around the leg 40 can be rectified, and the liquid can smoothly flow into the partition opening 21.

(Second embodiment)
Next, the gas-liquid separation device according to the second embodiment will be described with reference to FIGS. 6 to 8.

The second embodiment shown in FIGS. 6 to 8 is mainly different in that a swirl prevention member is provided in the liquid storage portion, and other configurations are the same as those of the first embodiment shown in FIGS. 1 to 5. Is almost the same as the form. 6 to 8, the same parts as those of the first embodiment shown in FIGS. 1 to 5 are designated by the same reference numerals and detailed description thereof will be omitted.

In the present embodiment, as shown in FIG. 6, the liquid storage portion 12 is provided with a swirl prevention member 90. The swirl prevention member 90 is a member for preventing swirling motion of the liquid stored in the liquid storage portion 12, and is provided in the lower portion of the container 10.

As shown in FIGS. 6 and 7, the swirl prevention member 90 in the present embodiment includes four partition plates 92 (partition portions) that partition the liquid storage portion 12 into four areas 91 when viewed from above. I'm out. Each partition plate 92 is formed so as to extend in the radial direction with respect to the center of the liquid storage section 12 (the center of the container 10) when viewed from above. The four partition plates 92 are arranged at 90° intervals in the circumferential direction of the liquid storage section 12 when viewed from above. The four partition plates 92 may be integrally formed. For example, the four partition plates 92 may be welded to each other so that they are formed in a cross shape when viewed from above.

As shown in FIG. 6, a communication opening 93 may be provided between the lower end of each partition plate 92 and the bottom surface of the container 10. The areas 91 adjacent to each other communicate with each other through the communication opening 93. The upper end of each partition plate 92 may be arranged in the vicinity of the partition plate 20 so as to be located above the liquid surface of the liquid stored in the liquid storage section 12. Further, each partition plate 92 may be connected (or contacted) with a part of the partition plate 20.

As described above, according to the present embodiment, the liquid storage section 12 is provided with the swirl prevention member 90 for preventing the swirling motion of the liquid stored in the liquid storage section 12. As a result, the swirling motion of the liquid stored in the liquid storage portion 12 can be prevented. Therefore, it is possible to prevent the liquid level of the liquid stored in the liquid storage unit 12 from changing.

Further, according to the present embodiment, the swivel prevention member 90 includes the partition plate 92 that partitions the liquid storage section 12 into a plurality of sections 91 in the circumferential direction of the liquid storage section 12 when viewed from above. .. As a result, the liquid storage section 12 can be divided into a plurality of pieces in the circumferential direction. Therefore, the swirling flow of the liquid stored in the liquid storage portion 12 can be blocked, and the swirling motion of the liquid can be effectively prevented.

Further, according to the present embodiment, the communication opening 93 is provided between the partition plate 92 and the bottom surface of the container 10.
