Description

Technical Field

[0001] The present invention relates to a gas-liquid separation humidifier. More specifically, by changing the structure of the humidifier and ensuring gas-liquid separation performance, it protects the turbine wheel, improves the deterioration of the humidification membrane, reduces the amount of liquid droplets remaining inside the humidifier, and prevents the liquid droplets from accumulating inside the humidifier, thereby minimizing the supply of a large amount of liquid droplets to the turbine in the transient section. The present invention relates to a gas-liquid separation humidifier.

Background Art

[0002] A fuel cell system is a system that continuously produces electrical energy through the chemical reaction of continuously supplied fuel, and continuous research and development has been carried out as an alternative to solve global environmental problems.

[0003] Fuel cell systems can be classified into phosphoric acid fuel cells (PAFC), molten carbonate fuel cells (MCFC), solid oxide fuel cells (SOFC), polymer electrolyte membrane fuel cells (PEMFC), alkaline fuel cells (AFC), and direct methanol fuel cells (DMFC) according to the type of electrolyte used. Together with the type of fuel used, they can be applied to various application fields such as mobile power sources, transportation, and distributed power generation according to the operating temperature, output range, etc.

[0004] Among these, polymer electrolyte membrane fuel cells are applied in the field of hydrogen vehicles (hydrogen fuel cell vehicles) developed as an alternative to internal combustion engines.

[0005] Hydrogen vehicles are configured to generate their own electricity through a chemical reaction between hydrogen and oxygen, which then drives a motor to propel the vehicle. More specifically, a hydrogen vehicle may include a hydrogen tank for storing hydrogen (H2), a fuel cell stack for producing electricity through the oxidation-reduction reaction of hydrogen and oxygen (O2), a battery for storing the electricity produced by the fuel cell stack, a controller for converting and controlling the produced electricity, and a motor for generating propulsion.

[0006] On the other hand, the gas emitted from the cathode of a fuel cell contains not only air that is discarded after being used in the fuel cell reaction, but also water vapor and liquid droplets. If these liquid droplets enter the turbine, they could potentially shock the high-speed rotating turbine wheel.

[0007] Therefore, appropriately limiting the amount of liquid droplets flowing into the turbine wheel can be considered one of the prerequisites for the smooth operation of a turbine-integrated air compressor.

[0008] Conventionally, a gas-liquid separator has been used at the front of the turbine to protect the turbine wheel from droplets. However, using a gas-liquid separator requires securing space for its installation, and when considering the package-related prerequisites that must be met for the efficiency of the gas-liquid separator, such as vertical or horizontal types, there is a problem in that the degree of freedom of the package is greatly restricted.

[0009] Furthermore, the weight and cost of the gas-liquid separator itself, as well as the weight and cost of hoses and other components connecting the gas-liquid separator to other parts, increase the overall weight and cost of the system. [Overview of the project] [Problems that the invention aims to solve]

[0010] In view of the above points, the present invention aims to solve the above-mentioned problems and provides a gas-liquid separation humidifier that protects the turbine wheel, improves the deterioration of the humidifying membrane, and minimizes the amount of liquid droplets remaining inside the humidifier so that the droplets do not accumulate inside the humidifier, thereby minimizing the supply of a large amount of liquid droplets to the turbine during transient periods. [Means for solving the problem]

[0011] A gas-liquid separation humidifier for achieving the above-described objectives of the present invention comprises a housing having a humidification space inside, a humidification membrane arranged in the humidification space, and forming an inlet space with an inlet and an outlet space with an outlet; and a gas-liquid separation unit installed inside the housing to prevent droplets contained in the exhaust gas discharged from the fuel cell stack and flowing in through the inlet from coming into contact with the humidification membrane, while simultaneously allowing them to be discharged to the outside.

[0012] Here, the gas-liquid separation unit may be located below the inlet inside the housing and may include a droplet guide that guides the movement of the exhaust gas.

[0013] Furthermore, the droplet guide may be installed below the inlet so as to be in contact with the inlet, or it may be installed on the bottom surface of the housing at a predetermined distance from the inlet.

[0014] Furthermore, the droplet guide may be positioned perpendicular to the horizontally formed inner surface of the housing, or at an angle.

[0015] Furthermore, the droplet guide may be provided in the form of a mesh with multiple pores formed on the plate surface.

[0016] Furthermore, the gas-liquid separation unit may be positioned below the outlet inside the housing, which is formed horizontally, and may include a plate-shaped droplet-blocking upper partition wall that prevents droplets contained in the exhaust gas from being discharged to the outside.

[0017] Furthermore, the upper droplet-blocking partition wall may be in contact with the lower side of the outlet and positioned perpendicularly to the horizontally formed inner surface of the housing, or at an angle.

[0018] Furthermore, a gas-liquid separation chamber may be formed on the bottom surface of the housing below the outlet, which communicates with the humidification space of the housing and collects the separated liquid droplets.

[0019] Furthermore, the upper part of the gas-liquid separation chamber may be provided with a droplet-blocking lower end partition wall that shields the upper surface of the gas-liquid separation chamber from the outside, in order to prevent droplets collected in the gas-liquid separation chamber from scattering.

[0020] Furthermore, the droplet-blocking lower end partition wall may include a first partition wall arranged along the width direction of the gas-liquid separation chamber and a second partition wall arranged along the height direction of the gas-liquid separation chamber.

[0021] The first partition wall may be positioned horizontally, or it may be positioned so that it is inclined downward toward the inside of the gas-liquid separation chamber as it approaches its ends.

[0022] Furthermore, the second partition wall may be positioned vertically, or it may be inclined so that it becomes closer to the wall surface of the gas-liquid separation chamber as it moves upward.

[0023] Furthermore, a discharge port is formed at the lower part of the gas-liquid separation chamber, allowing the collected liquid droplets to be discharged to the outside. A discharge valve may be installed at the discharge port to enable selective discharge of the collected liquid droplets.

[0024] In addition, in order to determine whether the discharge valve can be opened or closed, another water level sensor capable of measuring the water level of the collected liquid droplets can be installed on one side of the gas-liquid separation chamber.

[0025] Further, on the bottom surface of the housing, a bypass hole formed through a partition plate that partitions the inflow space and the discharge space is provided so that the liquid droplets contained in the exhaust gas flowing in through the inflow port flow along the bottom surface of the housing and are discharged to the gas-liquid separation chamber side.

[0026] Also, a plurality of the bypass holes can be formed along the width direction of the partition plate.

Advantages of the Invention

[0027] As described above, the gas-liquid separation humidifier according to the present invention protects the turbine wheel, improves the deterioration of the humidification film, and reduces the amount of liquid droplets remaining inside the humidifier by ensuring gas-liquid separation performance through structural changes of the humidifier. By preventing the liquid droplets from accumulating inside the humidifier, it is possible to minimize the supply of a large amount of liquid droplets to the turbine during the transient period.

[0039] As illustrated in these drawings, the gas-liquid separation humidifier according to the present invention comprises a housing 100 having a humidification space 101 inside, a humidification membrane 110 placed in the humidification space 101, and an inlet space 120 provided with an inlet 121 and an outlet space 130 provided with an outlet 131, and a chamber installed inside the housing 100 so as to collect droplets contained in the exhaust gas discharged from the fuel cell stack and flowing in through the inlet 121, and at the same time discharge them to the outside.

[0040] Here, the chamber can be configured with a gas-liquid separation unit 200 that prevents liquid droplets from coming into contact with the humidifying film 110 and separates the gas and liquid.

[0041] The housing 100 is equipped with a humidification space 101 inside, which is divided by a partition plate 140 into an inlet space 120 into which exhaust gas discharged from the fuel cell stack flows, and an outlet space 130 into which the flowing exhaust gas is discharged.

[0042] Furthermore, a humidifying membrane 110 is formed inside the housing 100. The humidifying membrane 110 allows dry air to flow in contact with its inner surface and humid air to flow in contact with its outer surface, thereby transferring moisture from the humid air to the dry air and enabling humidification of the dry air.

[0043] An inlet 121 is formed on one side of the inlet space 120, which serves as a passage for exhaust gas to flow in, and an outlet 131 is formed on one side of the discharge space 130, which serves as a passage for exhaust gas to be discharged.

[0044] The gas-liquid separation unit 200 is installed inside the housing 100 and separates liquid droplets contained in the exhaust gas flowing into the housing 100, ensuring that the exhaust gas does not contain liquid droplets when it is discharged to the outside through the outlet 131.

[0045] By removing liquid droplets from the exhaust gas, even if the exhaust gas, after passing through the housing 100 of the gas-liquid separation humidifier according to the present invention, flows into the turbine side where it is rotating at high speed, damage to the turbine wheel can be prevented.

[0046] Such a gas-liquid separation unit 200 is located below the inlet 121 inside the housing 100 and may include a droplet guide 210 that guides the movement of the exhaust gas. The droplet guide 210 can consist of one or more units and may be made of metal, plastic, rubber, etc. The plate surface may have multiple pores formed through it or may not have any pores.

[0047] However, if the plate surface is formed in a mesh-like manner with multiple pores that penetrate through it, it is preferable that the pore diameter be made small enough so that only moist air can pass through and liquid droplets cannot, in order to minimize the decrease in humidification performance.

[0048] The droplet guide 210 may be installed on the bottom surface of the housing 100 at a predetermined distance from the inlet 121, as shown in Figures 1 and 2, or it may be installed below the inlet 121 so as to be in contact with the inlet 121, as shown in Figures 3 and 4.

[0049] As shown in Figures 1 and 2, when the droplet guide 210 is installed on the bottom surface of the housing 100, separated from the inlet 121 by a predetermined distance, it has the effect of allowing the exhaust gas flowing into the humidification space 101 of the housing 100 via the inlet 121 to flow quickly into the exhaust space 130.

[0050] Furthermore, as shown in Figures 3 and 4, when the droplet guide 210 is installed below the inlet 121 in contact with the inlet 121, it has the effect of preventing diffusion within the inlet space 120 when exhaust gas flows in through the inlet 121, and allowing it to move quickly to the discharge space 130 along the droplet guide 210.

[0051] The droplet guide 210 may be positioned perpendicular to the inner surface of the housing 100, which is formed horizontally, or it may be positioned at an angle. When the droplet guide 210 is positioned at an angle, the angle of inclination may vary depending on the size of the humidifier, and the length of the droplet guide 210 should also vary depending on the size of the humidifier.

[0052] Furthermore, when installing the droplet guide 210 inside the housing 100, it is preferable that the ends of the droplet guide 210 do not penetrate the window side in order to minimize the reduction in the humidification performance of the humidifier.

[0053] The gas-liquid separation unit 200 is located below the outlet 131 inside the horizontally formed housing 100 and may include a plate-shaped droplet-blocking upper partition wall 220 to prevent droplets contained in the exhaust gas from being discharged to the outside.

[0054] The droplet-blocking upper end partition wall 220 contacts the lower side of the outlet 131 and may be positioned perpendicular to the horizontally formed inner surface of the housing 100, or it may be positioned at an angle, the angle at which it is positioned at an angle may vary depending on the size of the humidifier, and its length may also be formed to vary depending on the size of the humidifier, and the number of droplet-blocking upper end partition walls 220 may be one or more.

[0055] Furthermore, the end of the droplet-blocking upper bulkhead 220 must be configured to prevent intrusion from the window side. Its material can be metal, plastic, rubber, etc., and both porous and non-porous forms can be installed. However, if pores are formed, it is effective to make the diameter of the pores small enough so that droplets cannot pass through, and only moist air can pass through, in order to minimize the reduction in the energy recovery efficiency of the turbine.

[0056] A gas-liquid separation chamber 230 can be formed on the bottom surface of the housing 100 below the discharge port 131, which communicates with the humidification space 101 of the housing 100 and collects separated droplets. The gas-liquid separation chamber 230 has an opening at its top and is in communication with the discharge space 130.

[0057] Furthermore, a droplet-blocking lower end partition wall 240 can be provided at the top of the gas-liquid separation chamber 230 to shield the upper surface of the gas-liquid separation chamber 230 from the outside, in order to prevent droplets collected in the gas-liquid separation chamber 230 from scattering.

[0058] The droplet-blocking lower end partition wall 240 may include a first partition wall 241 arranged along the width direction of the gas-liquid separation chamber 230 and a second partition wall 242 arranged along the height direction of the gas-liquid separation chamber 230.

[0059] The first partition wall 241 may be positioned horizontally or inclined downward toward the inside of the gas-liquid separation chamber 230 towards its ends, and the second partition wall 242 may be positioned vertically or inclined toward the wall surface of the gas-liquid separation chamber 230 towards its upper side.

[0060] As shown in Figures 6 and 8, when the first partition wall 241 is positioned horizontally, not only can a large amount of liquid droplets be collected inside the gas-liquid separation chamber 230, but the area shielded by the first partition wall 241 on the upper surface of the gas-liquid separation chamber 230 can be maximized, thereby effectively preventing the scattering of liquid droplets.

[0061] As shown in Figures 5 and 7, when the first partition wall 241 is positioned so that it slopes downward toward the inside of the gas-liquid separation chamber 230 as it approaches its ends, it is possible to increase the efficiency of water collection by collecting even the droplets placed on the upper surface of the first partition wall 241 into the gas-liquid separation chamber 230.

[0062] Furthermore, the lower droplet-blocking partition wall 240, like the upper droplet-blocking partition wall 220, must be configured so that its end does not allow ingress from the window side. Its material may be metal, plastic, rubber, etc., and both porous and non-porous forms can be installed. However, if pores are formed, it is effective to form the pores with a diameter small enough that droplets cannot pass through, and only moist air can pass through, in order to minimize the reduction in the turbine's energy recovery efficiency.

[0063] As shown in Figure 9, a discharge port 231 is formed at the bottom of the gas-liquid separation chamber 230, which can discharge the collected liquid droplets to the outside. A discharge valve 232 can be installed at the discharge port 231 to enable selective discharge of the collected liquid droplets.

[0064] A discharge port 231 is formed at the bottom of the gas-liquid separation chamber 230, extending for a predetermined length. This allows for the discharge of large amounts of liquid droplets collected in the gas-liquid separation chamber 230 to the outside, enabling continuous collection of droplets. A discharge valve 232 is provided at the discharge port 231 to prevent the droplets from being discharged into the gas-liquid separation chamber 230 until they reach a predetermined level.

[0065] Furthermore, in order to determine whether or not to open or close the discharge valve 232, it is effective to install another water level sensor 233 on one side of the gas-liquid separation chamber 230 that can measure the water level of the collected droplets.

[0066] On the other hand, the bottom surface of the housing 100 may be provided with a bypass hole 150 formed through a partition plate 140 that separates the inlet space 120 and the discharge space 130, so that droplets contained in the exhaust gas that flows in through the inlet 121 can flow along the bottom surface of the housing and be discharged towards the gas-liquid separation chamber 230.

[0067] These bypass holes 150 are formed at multiple locations along the width direction of the partition plate 140, and multiple bypass holes may be provided. The bypass holes 150 serve to move droplets that move to the bottom surface of the inflow space 120 towards the gas-liquid separation chamber 230, allowing them to be immediately discharged to the outside.

[0068] Furthermore, it is preferable that the bottom surface of the housing 100 be formed smoothly and without steps so that droplets can be quickly moved to the gas-liquid separation chamber 230 side through the bypass hole 150.

[0069] Since not only liquid droplets but also air inside the housing 100 can flow through such bypass holes 150, this may affect the humidification performance. Therefore, it is effective to make the position, number, and area of ​​the windows adjustable to prevent a decrease in humidification performance.

[0070] As shown in Figure 10, the bottom surface of the housing 100 below the inlet 121 is provided with an auxiliary gas-liquid separation chamber 250 that communicates with the humidification space 101 of the housing 100 and collects separated droplets. Another bypass member 260 may be installed between the auxiliary gas-liquid separation chamber 250 and the gas-liquid separation chamber 230 to connect them.

[0071] Such a bypass member 260 is effective in allowing droplets collected in the auxiliary gas-liquid separation chamber 250 to flow smoothly into the gas-liquid separation chamber 230 by ensuring that there are no steps between the bottom surfaces of the gas-liquid separation chamber 230 and the auxiliary gas-liquid separation chamber 250, thus creating a flat, interconnected surface.

[0072] If necessary, the other side of the bypass member 260 connected to the gas-liquid separation chamber 230 may be positioned lower than one side of the bypass member 260 connected to the auxiliary gas-liquid separation chamber 250, so that droplets collected in the auxiliary gas-liquid separation chamber 250 can quickly flow into the gas-liquid separation chamber 230.

[0073] The gas-liquid separation humidifier according to the present invention, having the configuration described above, protects the turbine wheel, improves the deterioration of the humidifying membrane, and reduces the amount of liquid droplets remaining inside the humidifier, thereby minimizing the supply of a large amount of liquid droplets to the turbine during transient periods by ensuring gas-liquid separation performance through structural changes to the humidifier, reducing the amount of liquid droplets remaining inside the humidifier and preventing the accumulation of liquid droplets inside the humidifier.

[0074] The above description focuses on preferred embodiments achievable by the present invention. However, these are merely examples and do not limit the invention. A person with ordinary skill in the art to which the invention pertains will understand that various modifications and applications not exemplified above are possible, without departing from the essential characteristics of these embodiments. For example, each component specifically shown in the embodiments can be modified and implemented. Furthermore, any differences related to such modifications and applications should be interpreted as being within the scope of the invention as defined in the appended claims.
