Description

Technical Field

[0001] The present invention relates to a gas-liquid separation device for separating moisture contained in compressed air, and particularly to a gas-liquid separation device that can supply air to air blowing means (including a container) that receives air dried by the gas-liquid separation device.

Background Art

[0002] When compressed air containing water vapor flowing into a container passes through fluid control holes formed in a partition plate member having a cylindrical, kettle-shaped, inverted umbrella-shaped or the like that controls streamlines constituting a flow layer, the speed of air (airflow) increases, and as a result, it has the effect of not allowing high-density substances to pass through, and has the performance of removing water droplets and foreign substances, which are high-density substances present in the compressed air. This is known to those skilled in the art.

[0003] First, in FIG. 8 of Patent Document 1, there is an intervening connection state between an air sending means that sends compressed air with high moisture density and an air blowing means that blows out dry air with low moisture density, and is fixedly provided inside a long cylindrical container, and has a gas-liquid separation means that separates moisture contained in the compressed air flowing into the inside into water droplets and replaces it with the dry air. A gas-liquid separation device is disclosed.

[0004] The gas-liquid separation means is composed of an inverted umbrella-shaped receiving plate 17 having a gas flow hole at the center and a large number of air holes 15 for fluid control fixed in a substantially horizontal state at the upper end of the receiving plate.

[0005] Although this gas-liquid separation means has the advantage that it can be manufactured at a low cost because of its very simple structure, it has the problem that it does not have the function of cooling the compressed air entering the long cylindrical container 2, and the contact area with the compressed air is small, etc., so that it is impossible to promote the liquefaction phenomenon while rectifying and condensing the compressed air. (The reference numerals are those of Patent Document 1). Next, Patent Document 2 describes a gas-liquid separation device created by the inventor of the present application. However, although the gas-liquid separation means installed vertically in the internal space of the cylindrical partition plate of this gas-liquid separation device has multiple annular protrusions and recesses on its outer surface from the upper end to the lower end, it has the problem that, similar to Patent Document 1, it does not have the function of cooling the compressed air that has entered the long cylindrical container, and the area in contact with the compressed air is small, so it cannot promote the liquefaction phenomenon while rectifying and condensing the compressed air. [Prior art documents] [Patent Documents]

[Effects of the Invention]

[0013] By employing a simple gas-liquid separation mechanism, the compressed air that flows into the container body Controlling the flow This can accelerate the liquefaction phenomenon.

[0014] In other words, (1) the first gas-liquid separation means of the first embodiment has either a radial first cooling fin that guides the compressed air flow in a straight manner from the intake side of the elongated cylindrical container to the inner surface of the bottom wall of the elongated cylindrical container, or a radial second cooling fin that changes direction from the inner surface of the bottom wall of the elongated cylindrical container to the lower end opening of the cylindrical body and guides the air flow during gas-liquid separation that has entered the cylindrical body upward in a straight manner.

Therefore, the compressed air flowing into the container body can be efficiently induced in a rectified state to the inner peripheral wall side of the container body, and condensation can be promoted. Furthermore, the term "umbrella shape" refers to a shape where the circumferential surface, formed in an inclined manner from the edge of the upper opening to the edge of the lower opening, appears as an umbrella shape overall, as is clear from the descriptions in Figures 4 and 15, which show the second embodiment. Umbrella shapes with a vertex or mountain-shaped top surface at the upper opening are excluded from the umbrella shape outer cylinder as used herein.

Further, in the case of an embodiment (use invention) where the gas-liquid separation device is positioned on either the front side or the rear side of the air tank included in the line of the vehicle's air brake system, the molecular device included in the line of the vehicle's air brake system can still be presumed to adsorb a small amount of water vapor with respect to water droplet formation. Therefore, by removing the small amount of water vapor, the quality of the air brake system can be improved.

[0018] Figures 1 to 10 are explanatory diagrams relating to a gas-liquid separation apparatus according to a first embodiment of the present invention. (1) Gas-liquid separator...Figure 1 Figure 1 is a schematic diagram illustrating the main part of the present invention as seen from the front, showing an example of a gas-liquid separation device X. For example, the gas-liquid separation device X is interposed in a connected state between an air supply means A that supplies compressed air with a high density of moisture and an air blowing means B that blows out dry air with a low density of moisture.

[0019] In Figure 1, for example, symbol A represents an air supply means such as an air compressor, blower, or air pump that compresses air. The air supply means A has, for example, a gas storage function, an air generation function, and an air pressure supply function.

[0020] On the other hand, symbol B represents an air blowing means such as an air spray gun, air motor, air breaker, or moisture adsorption function. L1 is a supply pipe (supply line) that supplies compressed air a with high moisture content between the air blowing means B and the air supply means A, and L2 is an exhaust pipe (exhaust line) that supplies low-density dry air (gas) b, after water removal, to the air blowing means B. The lengths of the supply pipe L1 and the exhaust pipe L2 are set appropriately according to the applications of the air supply means A and the air blowing means B.

[0021] The gas-liquid separation device X has a container 1, and a manual or automatic container-type drain C is integrally or detachably attached to a liquid discharge portion that protrudes from the lower end of the container 1. The drain C is generally formed in the shape of a tank.

[0022] (2) Structure of container 1...Figures 1, 2, 3, 8 Figure 2 is an exploded perspective view of a metal container (container body 1a, lid 1b, and fastener 1c) 1, and Figure 3 is a schematic diagram of the main parts (the lid 1b with the tube attached and the connecting tube are shown in a longitudinal section, and the cylindrical body 8 (This is a perspective view.) Container 1 is, for example, a rectangular tube or a cylindrical (in this embodiment) Long cylindrical shape with an opening at the top It consists of a container body 1a and a lid 1b provided at the upper end of the container body, with an annular fastener 1c integrally connecting the container body 1a and the lid 1b.

[0023] The container body 1a has a drain port 2 in the lower center of its bottom wall for discharging the liquid after gas-liquid separation, while the lid 1b has an intake port 3 in a part of its peripheral wall (left side in Figure 1) for drawing in compressed air a supplied from the air supply means A, while an exhaust port 4 in a part of its peripheral wall opposite to the intake port 3 (right side in Figure 1) for discharging the dry air b after gas-liquid separation. Inside the lid 1b, a Landold annular space (a flow path similar to the C mark used in vision tests) 5 is formed, and a C-shaped guide wall 6 and horizontal support portion are provided to separate the intake port 3 and the exhaust port 4, with the base end of the guide wall connected to the inner peripheral wall of the lid (see Figure 8).

[0024] (3) Gas-liquid separation means...Figure 1 Multiple gas-liquid separation means 7 are fixedly installed inside the container 1. The gas-liquid separation means 7 in this embodiment consists of a cylindrical body 8 located in the internal space of the container body 1a, spaced apart from the inner circumferential wall of the container body, and a connecting cylinder 9 that is screwed into a threaded hole in a horizontal support portion continuous with the upper end of the cylindrical body and the lower end of the C-shaped guide wall portion 6 of the lid 1b, and has a partition plate-like obstruction portion 15 in which multiple small holes 15a for gas passage are formed. Here, the cylindrical body 8 is the first gas-liquid separation means, while multiple Small hole for gas passage The connecting cylinder 9 having 15a is referred to as the second gas-liquid separation means. Incidentally, the connecting cylinder 9 has a flange 9a, a cylindrical fitting portion 9b for the cylindrical body 8, a mounting portion 9c for the partition plate-like obstruction portion 15, and a cylindrical screw portion 9d that protrudes from the upper surface of the flange 9a (see Figure 7).

[0025] The second gas-liquid separation means, the obstruction portion 15, may be integrally molded from the same material (for example, synthetic resin or aluminum) as the flange 9a, fitting portion 9b, mounting portion 9c, and connecting screw-in cylindrical portion 9d. In this embodiment, the connecting cylinder 9 and the partition plate-shaped obstruction portion 15 are separate components, but the obstruction portion 15 is integrally attached to the lower end of the connecting cylinder 9 and connected to the horizontal portion of the lid 1b via the screw-in cylindrical portion 9d of the connecting cylinder 9.

[0026] Now, as shown in Figure 1, when the cylindrical body 8 is positioned vertically within the internal space of the container body 1a via the connecting cylinder 9, the lower end opening 10 of the cylindrical body 8 is located approximately in the center of the container body 1a, creating the required space between it and the aforementioned drop-off opening 2. For the sake of explanation, the lower end opening of the cylindrical body 8 is also referred to here as the "vent 10" through which air components enter. The cylindrical body 8 is divided into an upstream gas chamber on the intake port 3 side and a downstream gas chamber on the exhaust port 4 side, with the vent 10 as the reference point. Although not specifically shown, it is preferable to provide a liquid splash prevention partition member formed in the shape of a vertical funnel in cross-section on the inner surface of the bottom wall of the container body 1a (see, for example, Figure 3 of Japanese Patent No. 5467180).

[0027] (4) Specific configuration of the gas-liquid separation means... for example, Figures 3 to 7 First, the cylindrical body (first gas-liquid separation means) 8 constituting the gas-liquid separation means 7 of the first embodiment consists of an outer cylinder 11 having a number of first cooling fins extending radially outward and an inner cylinder 13 having a number of second cooling fins extending radially inward. The number of first cooling fins 12 of the cylindrical body 8 guide the airflow of high-density compressed air a rectified flow while cooling it from the intake port 3 side of the lid 1b of the container 1 to the inner surface of the bottom wall of the container 1.

[0028] In contrast, the numerous second cooling fins 14 of the cylindrical body 8 pass through the first cooling fins 12, fold back on the inner surface of the bottom wall, change direction from the inner surface of the bottom wall of the container body towards the lower end opening (vent) 10 of the cylindrical body, and guide the airflow undergoing gas-liquid separation that has entered the cylindrical body toward the upper end opening while further cooling it.

[0029] In addition, the cylindrical body 8 consists of an outer cylinder 11 on which the first cooling fins 12 are integrally provided on its outer circumference in a radially outward direction, and an inner cylinder 13 on which the outer circumference of the outer cylinder is in close contact with the inner circumference of the outer cylinder, and the second cooling fins 14 are integrally provided on the inner circumference of the inner cylinder in a radially inward direction. The space between the outer circumference of the outer cylinder 11 and the inner circumference of the container body 1 forms a first flow path through which the downward component of the airflow, which is rectified by the first cooling fins 12, passes. In this embodiment, the first cooling fins 12 and the second cooling fins 14 are substantially straight blades along the longitudinal direction of each cylindrical body, but at least one of the first cooling fins 12 or the second cooling fins 14 may be shaped in a slightly spiral or curved shape in order to increase the contact area with the airflow.

[0030] Next, the connecting cylinder (second gas-liquid separation means) 9, which constitutes the gas-liquid separation means 7 of the first embodiment, has its upper end cylindrical threaded portion 9d connected to the exhaust side of the lid 1b, and its lower end connected to the upper end of the cylindrical body 8 in an external fitting state, and the airflow during gas-liquid separation is passed through the numerous flow control small holes 15a of the obstruction portion 15, thereby further removing moisture from the airflow during gas-liquid separation. As described above, the cylinder 9 has a flange 9a at the upper end of the large-diameter section, a thick-walled fitting section 9b below the flange, and a tapered mounting section 9c below the fitting section. On the other hand, a cylindrical threaded section 9d is formed on the upper surface of the flange 9a, and this cylindrical threaded section 9d is screwed into a female thread formed in the horizontal support section of the lid 1b. When the connecting cylinder 9 is screwed into the horizontal support section of the lid 1b, the central hole of the connecting cylinder 9 and the exhaust port 4 of the lid 1b are in communication. The small gas passage holes 15a of the obstruction section 15 are formed in a through-shape from the bottom surface to the top surface. In addition, numerous through-shape gas passage holes 15a are formed radially, and they are in communication with the internal space of the inner cylinder 12 and the central hole of the connecting cylinder 9, respectively. The flow control holes 15a are, for example, about 1 to 2 mm in size.

[0031] Incidentally, in relation to the problem of the invention, which is to promote the liquefaction phenomenon while rectifying and condensing compressed air, the gas-liquid separation means 7 is composed of a cylindrical body (first gas-liquid separation means) 8 having a first cooling fin radially outward and a second cooling fin radially inward, and a partition plate-like obstruction part 15 interposed between the cylindrical body and the lid, which allows the airflow during gas-liquid separation to pass through a number of flow control holes, thereby further removing moisture from the airflow during gas-liquid separation. It is desirable that the gas-liquid separation means 7 (8, 15) be a heat-absorbing member made of a highly thermally conductive material such as aluminum or copper that removes heat from the airflow during liquid separation. In such an embodiment, at least the first gas-liquid separation means 8 has the structure of a simple cooler, so it can be manufactured inexpensively, and the compressed air that flows into the container body 1a is distributed throughout cooling By doing so, condensation can be actively generated, thereby promoting a greater degree of liquefaction.

[0032] Therefore, in addition to the cylindrical body 8 (outer cylinder 11 and inner cylinder 13 in the embodiment) as the first gas-liquid separation means, the gas-liquid separation means 7 includes a second gas-liquid separation means, an obstruction 15 whose upper end is connected to the exhaust side of the lid 1b and whose lower end is connected to the upper end of the upper end opening of the cylindrical body 8, and which allows the airflow during gas-liquid separation to pass through a number of flow control holes 15a, thereby further removing moisture from the airflow during gas-liquid separation. By the way, the cylindrical body 8, the first and second cooling fins 12 and 14, and the obstruction part 15 are in the gas-liquid separation process. Cool the air The heat-absorbing member is made of either aluminum or copper, a material with high thermal conductivity, and the heat from the heat-absorbing member is released from outside the container 1 via the connecting cylinder 9 and the lid 1b. Go out .

[0033] However, in order to reduce the contact resistance with the air component, it is preferable to appropriately select materials with high thermal conductivity for each component, including the cylindrical body 8, the first and second cooling fins 12 and 14, the obstruction part 15, the connecting cylinder 8, and the lid 1b, taking into consideration factors such as the contact pressure with the air component, the contact area, the surface roughness of the contact surface, the thermal conductivity of each material, the length and thickness of each component, and the hardness of each component. For this reason, aluminum or copper, and their alloys, are naturally included.

[0034] (5) Streamline direction of air components First, the upper schematic diagram (a) in Figure 8 shows the streamlines of compressed air a flowing into the lid 1b of container 1, and the lower schematic diagram (b) shows the streamlines of compressed air that change direction within the lid 1b and flow downward. As mentioned above, a Landold annular space (a flow path similar to the C mark used in vision tests) 5 is formed between the inner circumferential wall of the lid 1b and the C-shaped guide wall in plan view. Therefore, the streamlines of compressed air a entering the internal space from the intake port 3 split into clockwise and counterclockwise directions, as indicated by the arrows. The split air components are blocked by the inner wall of the upper wall of the lid and flow downward, as shown in schematic diagram (b).

[0035] Next, the upper schematic diagram (c) of Figure 9 shows the streamlines of compressed air flowing from the lid 1b side toward the flow path between the inner circumferential wall at the upper end of the container body 1a and the outer circumferential wall of the outer cylinder 11 of the cylindrical body 8, and the lower schematic diagram (d) shows the streamlines of compressed air that change direction by swirling around the inner wall at the lower end of the container body 1a and toward the lower end opening 10 of the outer cylinder 11. In Figure 9, the compressed air descends while contacting the inner circumferential wall at the upper end of the container body 1a, the outer circumferential wall of the outer cylinder 11 of the cylindrical body 8 and the surfaces of the numerous radial first cooling fins 12. At this time, the moisture-containing air is guided toward the surfaces of the first cooling fins 12 and rectified toward the downward direction, and is cooled by the outer circumferential wall of the outer cylinder 11 and the numerous radial first cooling fins 12.

[0036] Furthermore, by allowing moisture in the compressed air to come into contact with the outer circumferential wall of the outer cylinder 11 and the surfaces of the numerous radially arranged first cooling fins 12, condensation can be actively generated, thereby promoting the liquefaction phenomenon. Here, the compressed air is cooled temporarily, which efficiently causes the water droplet phenomenon to occur, and impurities (substances with a specific gravity greater than air) can be removed from the gas.

[0037] Next, the upper schematic diagram (e) of Figure 10 shows the streamlines of compressed air entering the internal space of the cylindrical body, and the lower schematic diagram (f) shows the streamlines of dry air passing through the baffle plate and connecting pipe. In this embodiment, the inner cylinder 13 is also provided with second cooling fins 14, so the cold compressed air entering from the lower end opening 10 of the inner cylinder 13 is further cooled secondarily by contacting the inner circumferential wall of the inner cylinder 13 and the surfaces of the numerous radially arranged second cooling fins 14.

[0038] Therefore, condensation further promotes the liquefaction phenomenon, and droplet formation occurs efficiently within the inner cylinder 13, allowing impurities (substances with a specific gravity greater than air) to be removed from the gas. Then, as shown in schematic diagram (f), the compressed air during gas-liquid separation, which has been secondarily cooled, passes through the numerous flow control holes 15a of the partition plate-shaped obstruction 15, and as it passes through, moisture is further removed from the airflow during gas-liquid separation, becoming dry air b which is then discharged from the exhaust port 4.

[0039] It is known to those skilled in the art that when air passes through fluid control holes formed in the partition plate member, the velocity of the air (airflow) increases, resulting in an effect that prevents high-density substances from passing through, and thus has the ability to remove water droplets and foreign matter, which are high-density substances present in compressed air. [Examples]

[0040] This section briefly describes other embodiments of the cylindrical body 8A that constitute the gas-liquid separation means. Furthermore, other embodiments of the cylindrical body of the present invention will be described with reference to Figures 11 to 13. Additionally, the gas-liquid separation means 7A of the second embodiment of the present invention will be described with reference to Figures 14 to 21. Finally, a novel application example of the present invention will be described with reference to Figure 22. In describing these embodiments, parts identical to those in the first embodiment are denoted by the same or similar reference numerals, and redundant explanations are omitted.

[0041] First, Figure 11 is a perspective view showing a second embodiment of the cylindrical body 8A of the present invention, and Figure 12 is a cross-sectional view taken along line 12-12 of Figure 11. As can be seen from Figures 11 and 12, the main difference between the cylindrical body 8A of the second embodiment and that of the first embodiment is that the cylindrical body 8A consists of "one" cylinder. Numerous first cooling fins extend radially outward from the outer circumferential surface of this single cylinder, and numerous second cooling fins 14A extend radially inward from the inner circumferential surface of the same single cylinder. The contact area of ​​the numerous first cooling fins 12A and second cooling fins 14A, the surface roughness of the contact surfaces, the thermal conductivity of each material, the length and thickness of each component, and the hardness of each component are all appropriately designed.

[0042] Next, Figure 13(a) shows an embodiment in which the cylindrical body 8B has cooling fins 12B only in the radially outward direction, and Figure 13(b) shows an embodiment in which the cylindrical body 8C has cooling fins 14B only in the radially inward direction.

[0043] Next, a second embodiment of the present invention will be described with reference to Figures 14 to 21. The main differences from the first embodiment of the present invention described above are as follows.

[0044] (a) The first gas-liquid separation means 8D of the gas-liquid separation means 7A provides a plurality of means that guide the airflow of compressed air in a straight manner from the intake port 3 side of the container 1 to the inner surface of the bottom wall of the elongated cylindrical container. As a linear depression The second gas-liquid separation means 9A consists of an umbrella-shaped outer cylinder 11A having grooved lines 21 on its outer surface and an inner cylinder 13A integrally provided on the outer cylinder. The second gas-liquid separation means 9A is provided at the lower end of the connecting cylinder 9 connected to the lid 1b and is a partition plate-shaped obstruction (9c=15A) having a plurality of small gas passage holes 15a that further remove moisture from the airflow during gas-liquid separation that has entered the inside of the inner cylinder 13A. The definition of "umbrella-shaped" is as previously stated.

[0045] (b) In addition, the second gas-liquid separation means has at least a connecting cylinder 9A, and the obstruction portion (9c=15A) of this connecting cylinder 9A is integrally formed with the lower end of the fitting portion 9b in a thicker form using the same material. The multiple small holes 15a for gas passage are preferably formed to penetrate from the outer circumferential surface to the inner circumferential surface of the partition plate-like obstruction portion 15A.

[0046] (c) The small holes 15a for gas passage are formed at predetermined intervals in the circumferential direction on the outer surface, for example, 6 to 8 in number, and are in communication with the flow path of the connecting cylinder 9A.

[0047] (d) A columnar connecting portion 23 is formed to protrude downward from the center of the lower surface of the partition plate-like obstruction portion 15 of the connecting cylinder 9A. This connecting portion 23 is used to connect two, three, or more gas-liquid separation means 7A in the vertical direction, for example, when there are multiple gas-liquid separation means 7A of the same configuration, by tightly fitting the cylindrical threaded portion 9d of the gas-liquid separation means 7A located below to the connecting portion 23 when there are multiple gas-liquid separation means 7A located above.

[0048] (e) Formed on the outer surface of the umbrella-shaped outer cylinder 11A from the upper end to the lower end As a linear depression The grooved sections 21 have the function of cooling the compressed air a. A way to align the flow of droplet-like water in one direction.It is provided for the purpose of straightening the flow and causing the droplets of water to collide with the inner wall surface of the container body 1b. Therefore, the inclination angle of the outer surface of the outer cylinder 11A can be set arbitrarily. In the embodiment, as shown in Figure 16, the grooved grooves 21 are spaced at predetermined intervals in the circumferential direction of the outer surface of the outer cylinder 11A. Many (for example, 8) It is formed.

[0049] (f) In this embodiment, the roughly cylindrical inner cylinder 13A is longer than the umbrella-shaped outer cylinder 11A. However, the difference in length between the two is not an essential aspect of the invention. Furthermore, an annular gap 22 is formed between the outer circumferential surface of the roughly cylindrical inner cylinder 13A and the inner circumferential surface of the outer cylinder 11A, but this annular gap 22 is also not an essential aspect of the invention.

[0050] On the other hand, since the gas that has entered the inner cylinder 13A during gas-liquid separation needs to flow into the flow path of the connecting cylinder 9A, a narrow annular gap 24 is required between the outer surface of the obstruction portion 15 at the lower end of the connecting cylinder 9A and the upper end of the inner surface of the inner cylinder 13A.

[0051] (g) The number of grooved grooves 21 and gas passage holes 15a can be set arbitrarily. The umbrella-shaped outer cylinder 11A and inner cylinder 13A of the gas-liquid separation means 7A are the same as in the first embodiment during gas-liquid separation. Cool the air It is preferable that the heat-absorbing component be made of either aluminum or copper, which are materials with high thermal conductivity.

[0052] Figure 20 shows the streamlines of compressed air a guided to the suction side 3 of the lid 1b and the first gas-liquid separation means 8A, as well as the state of water droplet fall. Figure 21 shows the streamlines of compressed air entering the internal space of the inner cylinder 13A, as well as the state of water droplet fall. Even with the configuration described above, the main objective of the present invention can be achieved in the same way as in the first embodiment.

[0053] Finally, Figure 22 is a schematic diagram illustrating another embodiment of an application example of the present invention. The gas-liquid separator X is an air tank included in the line of the vehicle's air brake system. hmm Ku Upstream or downstreamIt can be positioned in one of the following two categories. This is because the molecular equipment included in the vehicle's air brake system line can be presumed to still adsorb a small amount of water vapor with respect to droplet formation.

[0054] Figure 22 shows an embodiment in which the device is positioned in front of the air tank included in the air brake system line of a vehicle, for example. Although not specifically shown, since water vapor cools and turns into water droplets in the piping, the downstream area of ​​the line is considered better than the upstream area, so it is naturally possible to position it behind the air tank, taking into consideration the efficiency of water droplet removal.

[0055] Here, we will describe the embodiment shown in Figure 22. The gas-liquid separation device X of the present invention is interposed in a connected state between a vehicle compressor, which serves as an air supply means A for supplying compressed air, and a vehicle dry air storage unit, which serves as an air blowing means B for blowing out dry air with low moisture density. The density of the compressed air depends on the performance of the vehicle compressor.

[0056] In other words, the air supply means A in this embodiment is a compressor powered by the engine, electric motor, or capacitor mounted on a vehicle such as a train or automobile, and the vehicle compressor A is connected to the intake port 3 side of the container 1 via a first pipe 31 that supplies relatively high-density compressed air. On the other hand, the air blowing means B is a vehicle dry air storage device (for example, a molecular chemical dryer device) connected to the exhaust port 4 side of the container 1 via a second pipe 32, and the vehicle dry air storage device B is connected to an air tank 34 that constitutes the vehicle's air brake system Y via a third pipe 33.

[0057] Regarding the configuration of the vehicle's air brake system Y, reference numeral 35 denotes a brake pedal, 36 a brake valve, 37 a plurality of control valve devices including a differential pressure valve, 38 an air master, and 39 a brake device that applies braking to the wheels 40. Since the vehicle's air brake system Y is publicly known technology, a detailed explanation is omitted (for example, Japanese Patent Publication No. 6-1219).

[0058] In the above configuration, in particular, when the vehicle dry air storage unit B does not have a water droplet capture device, applying the liquid separation device X of the present invention can ultimately improve the performance and quality of the air brake system Y. [Industrial applicability]
