Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of priority from Korean Patent Application No. 10-2023-0109243 filed in the Korean Intellectual Property Office on August 21, 2023, the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present invention relates to a liquid droplet removal device. Background Art

[0004] A fuel cell is a device that converts the chemical energy stored in hydrogen fuel into electrical energy through an electrochemical reaction with air. Specifically, hydrogen ions generated at the anode of the fuel cell stack move to the cathode via an electrolyte, where they react with oxygen to generate water and electricity.

[0005] The generated water must be discharged from the fuel cell. The generated water can be discharged through the exhaust / discharge hole. However, when the generated water is discharged through the exhaust / discharge hole, droplets may splash (e.g., splash onto the rear vehicle, etc.), which may damage and / or reduce the value of the vehicle. Therefore, the air discharged through the exhaust / discharge hole preferably does not contain droplets.

[0006] An expander for recovering energy may be installed on the fuel cell. In this case, if the air flowing into the expander contains liquid droplets, the fuel ratio of the expander will decrease.

[0007] In particular, when a vehicle equipped with a fuel cell is turned on or off (i.e., just after starting or just after shutting down the vehicle), the water remaining in the humidifier is immediately discharged to the outside within about 10 to 30 seconds. In this case, the size of the discharged droplets is larger than that in a normal driving state (corresponding to the state after the vehicle is started and before it is shut down). Summary of the invention

[0008] The following summary presents a simplified overview of certain features. This summary is not an extensive overview and is not intended to identify key or critical elements.

[0009] The present invention describes a system, device and method for removing droplets (e.g., water). The device (e.g., a droplet / water removal device) may include: a body; a first separation component, which is disposed in the body and is configured to separate a first portion of water in a fluid introduced into the first separation component along a first direction; and a second separation component, which is disposed in the body on the first direction side of the first separation component and is configured to secondary separate a second portion of water in the fluid that is not separated by the first separation component. The body may include: an introduction channel, which is configured to guide the inflowing fluid along a first direction; a first body member, which is connected to the introduction channel in the first direction so that the interior of the first body member is connected to the interior of the introduction channel, wherein the diameter of the first body member is greater than the diameter of the introduction channel; a second body member, which is connected to the first body member in the first direction and includes a discharge port opening parallel to the first direction, wherein the diameter of the discharge port is smaller than the diameter of the introduction channel; and a drainage channel, which is connected to one side of the first body member in a second direction perpendicular to the first direction and is configured to discharge the first portion of water and the second portion of water.

[0050] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that when reference numerals are added to components of the accompanying drawings, the same components are represented by the same reference numerals even if they are drawn in different drawings. In addition, when describing embodiments of the present invention, if it is determined that a detailed description of related known configurations and / or functions would hinder the understanding of the embodiments of the present invention, the detailed description thereof will be omitted.

[0051] The present invention discloses a liquid droplet removal device (eg, moisture removal device / apparatus, moisture remover, gas / liquid separator) which can be mounted to a fuel cell portion of a vehicle and has a high separation efficiency for removing large liquid droplets.

[0052] The liquid droplet removal device according to an embodiment of the present invention may be a liquid droplet removal device suitable for a fuel cell system. The liquid droplet removal device may be used to remove moisture from gas discharged (eg, discharged to an exhaust port) by a humidifier of the fuel cell system.

[0053] As an example, the droplet removal device may be disposed on the downstream side of a pressure control valve connected to a humidifier of the fuel cell system. The droplet removal device may be disposed on the upstream side of an expander of the fuel cell system.

[0054] In the present invention, expressions such as "upstream side" and "downstream side" may be based on the flow direction of the fluid. For example, if the fluid flows from the left side to the right side, the left side may correspond to the upstream side, and the right side may correspond to the downstream side. In the present invention, the fluid may refer to air containing moisture.

[0055] According to embodiments of the present invention, a droplet removal apparatus may be used in various applications, such as aircraft, Urban Air Mobility (UAM), ships, and / or hydrogen fuel cell vehicles.

[0056] Figure 1 FIG. 1 is a perspective view showing a droplet removal apparatus according to an embodiment of the present invention. Figure 2 To show Figure 1 A view of the internal structure of the droplet removal device. Figure 3 for Figure 1 Exploded perspective view of a droplet removal device. Figure 4 It is a view conceptually showing a first separation component. Figure 5 It is an exploded perspective view of the second separation component.

[0057] The liquid droplet removal device according to an embodiment of the present invention may include a main body part 100 (e.g., a main body), a first separation part 200 (e.g., a first separator, a first gas / liquid separator), and a second separation part 300 (e.g., a second separator, a second gas / liquid separator). The first separation part 200 may be disposed in the main body part 100, and / or may be configured to perform a primary separation of water in a fluid introduced therein along a first direction D1. The second separation part 300 may be located on the first direction D1 side of the first separation part 200, and / or may be configured to perform a secondary separation of water in the fluid that has not been separated by the first separation part 200.

[0058] As an example, the first separation component 200 may utilize a condensate tank structure to initially separate the water in the fluid. The second separation component 300 may utilize a separator structure to secondary separate the water in the fluid. However, the first separation component 200 utilizes a separator structure to initially separate the water in the fluid, and the second separation component 300 utilizes centrifugal force to secondary separate the water in the fluid, which may also be considered to be within the scope of the present invention, as a method that can be easily modified by a person of ordinary skill in the art.

[0059] <Main body 100>

[0060] The body part 100 may include an introduction channel 110, a first body member 120 (e.g., a first body), a second body member 130 (e.g., a second body), and a drainage channel 140. The introduction channel 110 may guide the inflowing fluid along a first direction D1. Hereinafter, the inflow direction of the fluid is defined as the first direction D1, and a direction perpendicular to (and / or at least not parallel to) the first direction D1 is defined as a second direction D2.

[0061] As an example, the introduction channel 110 may have a shape in which the end portion of the opposite direction side of the first direction D1 is closed. Then, the main body part 100 may further include an eccentric introduction channel 111. The eccentric introduction channel 111 may extend from one side of the introduction channel 110 in the first direction D1 in a direction intersecting the first direction D1. That is, the shape obtained by combining the introduction channel 110 and the eccentric introduction channel 111 may be a shape similar to an "L" shape.

[0062] The diameter of the eccentric introduction channel 111 (e.g., the diameter of the circular cross section in the D1 direction, the average / maximum / minimum width of the non-circular cross section in the D1 direction) can be smaller than the diameter of the introduction channel 110. The eccentric introduction channel 111 can be connected to a position biased to the upper side or the lower side of the introduction channel 110. Since the eccentric introduction channel 111 is connected to a position biased to the upper side or the lower side of the introduction channel 110, the fluid introduced through the eccentric introduction channel 111 forms a flow of a circular trajectory centered on the first direction D1 when introduced into the introduction channel 110. At the same time, the fluid will be subjected to a force moving along the first direction D1. Therefore, the fluid can draw a spiral trajectory extending along the first direction D1 when flowing. Due to this flow, the water in the fluid will be subjected to a force so that it tends to flow radially outward (e.g., by centrifugal force).

[0063] The first body member 120 may be connected to the side of the introduction channel 110 so that the inside thereof is communicated. The diameter of the first body member 120 may be greater than the diameter of the introduction channel 110. As an example, the first body member 120 may have a shape in which the diameter increases along the first direction D1. The area of ​​the maximum diameter of the first body member 120 may be 200 mm or less.

[0064] The second body member 130 may include a discharge port 131. The discharge port 131 may be opened in the first direction D1, and may have a diameter smaller than that of the introduction passage 110. The second body member 130 may be connected to the first direction D1 side of the first body member 120.

[0065] The drainage channel 140 may be connected to the second direction D2 side of the first main body member 120 and may be configured to discharge the water separated from the fluid. With the opposite direction of the first direction D1 as a reference, the extension direction of the drainage channel 140 may be a direction inclined toward the second direction D2. Since the drainage channel 140 has an inclined shape, when the droplet removal device is installed / oriented vertically and / or horizontally, the water can be naturally discharged in the direction of gravity. Here, vertical installation may mean a situation where the first direction D1 is an upward direction. The horizontal direction may mean a situation where the second direction D2 is a downward direction.

[0066] A region of the body part 100 adjacent to the drain channel 140 may be inclined toward the drain channel 140. That is, the body part 100 may have a gradient toward the drain channel 140 to guide moisture to the drain channel 140.

[0067] The body part 100 may have a moisture guide channel 141. The moisture guide channel 141 may have a shape penetrating the second body member 130. The moisture guide channel 141 may have a structure for guiding moisture generated on the first direction D1 side of the second body member 130 to the drain channel 140. As an example, the moisture guide channel 141 may have a specific inclination toward the drain channel 140.

[0068] The body part 100 may further include a third body member 150 (eg, a third body). The third body member 150 may be connected to the second body member 130 in the first direction D1 and its interior may communicate with the discharge port 131. The second separation part 300 may be disposed inside the third body member 150.

[0069] The body part 100 may further include a fourth body member 160 (eg, a fourth body). The fourth body member 160 may be connected to the first direction D1 side of the third body member 150.

[0070] The body part 100 may further include an air discharge passage 170. The air discharge passage 170 may be connected to the first direction D1 side of the fourth body member 160. The air discharge passage 170 may have a diameter smaller than that of the fourth body member 160. The air discharge passage 170 may be a passage through which a fluid flowing through the first separation part 200, the second separation part 300, and the heating part 400 (e.g., a heater) to be described below is discharged.

[0071] <First Separation Component 200>

[0072] The first separation part 200 may be disposed in the introduction channel 110. The first separation part 200 may separate moisture in the introduction channel 110 by centrifugal force.

[0073] As an example, the first separation part 200 may be formed in the second body member 130. As an example, the first separation part 200 may include at least one condensation groove 210. The condensation groove 210 may be formed on a side surface of the second body member 130 in a direction opposite to the first direction D1, and may be open in a direction opposite to the first direction D1.

[0074] A plurality of condensation grooves 210 may be formed. As an example, the plurality of condensation grooves 210 may have concentric shapes with different diameters. Since the condensation grooves 210 have a circular shape (e.g., a substantially circular shape and / or an arc shape), moisture in the fluid rotates along a circle (e.g., and / or an arc shape), and in this process, condensation may be performed more smoothly by centripetal force. As another example, the condensation grooves may be formed in a plurality of spiral shapes.

[0075] The moisture introduced into the introduction channel 110 may rotate due to being introduced via the eccentric introduction channel 111, and may collide with the surface of the second body member 130 facing the opposite direction of the first direction D1. The condensation groove 210 may be a space where the moisture that collides with the surface of the second body member 130 in the opposite direction of the first direction D1 may be condensed and / or flow. The moisture may be condensed and / or may be guided to the drainage channel 140 (e.g., in the form of droplets).

[0076] The first separation member 200 may further include a second guide groove 220. The second guide groove 220 may be formed to communicate with ends of the plurality of condensation grooves 210 in the second direction D2, may extend toward the second direction D2, and may be configured to guide moisture in the condensation grooves 210 to the drain channel 140.

[0077] <Second Separation Component 300>

[0078] The second separation part 300 may include a plurality of separation holes 311. The separation holes 311 may be configured so that droplets are formed. For example, the second separation part 300 may have a grid structure and / or include a grid-like object. Compared with the first separation part 200 using the centripetal force, the second separation part 300 can easily separate droplets of relatively large size.

[0079] As an example, the second separation part 300 may include: a second separation member 310 having a separation hole 311 , and / or a fixing member 320 configured to fix the second separation member 310 .

[0080] The second separation part 300 may be arranged so that the direction faced by the second separation part 300 intersects with the first direction D1 (for example, the direction faced by the second separation part 300 is not parallel or anti-parallel to the first direction D1). As an example, the second separation part 300 may be arranged so that the end of the second separation part 300 in the opposite direction of the second direction D2 is closer to the second body member 130 than the end of the second separation part 300 in the second direction D2. This may mean that, due to the shape of the fixing member 320, the second separation member 310 is arranged to be inclined relative to the first direction D1 as described above.

[0081] According to the present invention, since the second separation member 300 is disposed obliquely, the liquid droplets formed in the second separation member 310 may naturally drop in the second direction D2. The dropped liquid droplets may be guided to the drainage channel 140.

[0082] Accordingly, compared with the case where the second separating part 300 is disposed perpendicular to the first direction D1, the probability of the droplets passing through the second separating part 300 can be reduced.

[0083] The second separation member 310 may be folded in a zigzag shape, which can increase the volume-to-surface area of ​​the second separation member 310 and effectively block the flow of liquid droplets.

[0084] The fixing member 320 may have a bypass channel to prevent the fluid flow from being blocked. As an example, the bypass channel may have a hole shape. This is a structure designed to prevent the flow path from being blocked when the amount of droplet introduction is greater than the maximum limit amount of droplets that the second separation member 310 can separate.

[0085] <Heating Component 400>

[0086] Figure 6 4 is an exploded perspective view of a heating component 400. The droplet removal device according to an embodiment of the present invention may further include a heating component 400. The heating component 400 may be disposed inside the fourth body member 160 to heat the fluid. The heating component 400 may heat the fluid passing through the second separation component 300 and may prevent residual moisture in the fluid from condensing.

[0087] As an example, the heating member 400 may include a heater 410 and a heat sink 420. When viewed along the first direction D1, the heater 410 may have a cross region 411 in a cross shape and a peripheral region 412 surrounding the cross structure. The cross region 411 may be a region that may be heated to transfer heat to the heat sink 420. The peripheral region 412 may be a region that blocks the transfer of heat radiated from the cross region 411.

[0088] The heat sink 420 may be disposed between the cross region 411 and the peripheral region 412. The heat sink 420 may receive heat from the cross region 411 and may heat the fluid passing through the heat sink 420.

[0089] The heating part 400 may further include a power connection part. The power connection part may be a part exposed to the outside of the body part 100 to be electrically connected to an external power source.

[0090] The heating part 400 may further include a sealing member 430. The sealing member 430 may seal a gap between the heating part 400 and the body part 100. As an example, the sealing member 430 may include a first sealing member 430a and a second sealing member 430b. The first sealing member 430a may be disposed on the first direction D1 side of the peripheral area 412, and the second sealing member 430b may be disposed in the opposite direction thereto.

[0091] The first body member 120 may include a first guide groove 121. The first guide groove 121 may be recessed from the inner surface of the first body member 120 to guide the moisture separated from the fluid. In addition, or alternatively, a guide boss may protrude from the inner surface of the first body member 120 to guide the moisture separated from the fluid. As an example, the first guide groove 121 may be formed in a circular shape to guide the moisture separated from the fluid.

[0092] <Operation of the present invention>

[0093] In the following, reference will be made to Figure 7 and Figure 8 The operation of the present invention will be described in detail. First, the situation under a general driving condition will be described in detail, and then, the situation under a start is ON or OFF condition will be described in detail. Figure 7 The figure conceptually shows the flow of fluid under normal driving conditions. Figure 8 The diagram conceptually illustrates the flow of fluid in an activated or deactivated state.

[0094] Under normal driving conditions (when the vehicle is moving), the fluid may contain dry air, small droplets, large droplets, and saturated steam. The fluid flowing in through the introduction channel 110 will pass through the first separation component 200. By flowing through the first separation component 200, small droplets can be mainly removed from the fluid. The small droplets separated by the first separation component 200 can be discharged to the drainage channel 140.

[0095] The fluid passing through the first separation part 200 may pass through the second separation part 300. In this process, large droplets may be removed. The large droplets separated from the fluid via the second separation part 300 may be discharged through the drainage channel 140.

[0096] The fluid passing through the second separation part 300 may pass through the heating part 400. The saturated steam may be heated by the heating part 400, thereby preventing its condensation. Accordingly, the fluid passing through the heating part 400 may be finally discharged in a state where the ratio of dry air to saturated steam is high.

[0097] In the case of startup or shutdown, the moisture stored for about 10 seconds to 30 seconds will be discharged to the outside. In this case, there is almost no saturated vapor in the fluid, and large droplets account for the majority.

[0098] As in a general driving condition, the fluid flowing in through the introduction channel 110 may first remove small liquid droplets by passing through the first separation member 200. Therefore, the fluid passing through the first separation member 200 may be in a state where small liquid droplets are mainly removed.

[0099] The fluid passing through the first separation part 200 can pass through the second separation part 300. In the start-up or shutdown condition, the proportion of large droplets is very high, but the second separation part 300 physically blocks the flow of fluid through the grid structure, whereby the large droplets can be separated smoothly (for example, compared with the case of using only centrifugal force).

[0100] Accordingly, the fluid passing through the second separation element 300 can be discharged in a state where the ratio of dry air to saturated air is high.

[0101] The present invention aims to solve the above-mentioned problems in the prior art while maintaining the advantages of the prior art.

[0116] The direction in which the drainage channel extends may be a direction inclined toward the second direction based on the opposite direction of the first direction.

[0118] The diameter of the eccentric introduction passage may be formed smaller than the diameter of the introduction passage, and the eccentric introduction passage may be connected to a position offset to an upper side or a lower side of the introduction passage.

[0119] According to the present invention, all operations of droplet separation using centrifugal force, droplet separation by a separator, and droplet separation by heating can be performed, whereby the droplet separation efficiency can be improved.
