Description

Technical Field

[0001] The present invention relates to the field of gas-liquid separator equipment, and in particular to a gas-liquid separator and a vehicle having the same. Background Art

[0002] A hydrogen fuel cell is a power generation device that directly converts the chemical energy of hydrogen and oxygen into electrical energy. Its basic principle is to supply hydrogen and oxygen to the anode and cathode respectively. Hydrogen diffuses outward through the anode to react with the electrolyte, releasing electrons to reach the cathode through an external load. Hydrogen fuel cells are a very green and environmentally friendly energy source, which only produces water during the entire reaction process. In order to improve the utilization rate of hydrogen in fuel cells, the hydrogen after the anode reaction of the fuel cell stack will enter the stack through a hydrogen circulation pump or ejector to participate in the electrochemical reaction. Since hydrogen will carry a large amount of liquid water after participating in the electrochemical reaction inside the stack, if this part of the liquid water re-enters the anode of the stack with the hydrogen after the reaction, it will cause the anode of the stack to be "flooded", causing the performance of the stack to drop sharply. Therefore, a gas-liquid separator that can separate liquid water from hydrogen plays an indispensable role.

[0003] With the continuous development of the hydrogen fuel cell industry, various specifications and models of fuel cells have emerged one after another. As the core accessory of fuel cells, gas-liquid separators have correspondingly produced various models of products. The versatility between various products is poor, and the development process of gas-liquid separators runs counter to the modular development principle of the automotive industry.

[0004] The gas-liquid separators of the fuel cell system in the prior art are generally centrifugal and baffle types, and the separation effects of the two gas-liquid separators are different. The centrifugal gas-liquid separator is suitable for conditions with low flow rates, while the baffle gas-liquid separator is suitable for conditions with large flow rates. Therefore, no matter which gas-liquid separator is used, there will be a problem of poor liquid water separation effect under certain conditions. Depending on the type of vehicle the fuel cell system is equipped with, the fuel cell system will use a matching stack, and accordingly, the gas-liquid separator also needs to be redesigned or selected. This has resulted in the complexity and diversity of the specifications and models of the gas-liquid separator, which not only does not meet the requirements of the current modular platform, but also causes a huge waste of resources.

[0005] With respect to the above-mentioned problems in the prior art, no effective solution has been proposed yet. Summary of the invention

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

It should be understood that the terms used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0034] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in a variety of different forms and should not be construed as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for the sake of clarity, the thickness of the layers and regions may be enlarged, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0035] Combination Figures 1 to 4As shown, according to a specific embodiment of the present application, a gas-liquid separator is provided.

[0036] The gas-liquid separator includes a shell 10, a drive assembly 20, and a gas-liquid separation assembly. The shell 10 has a separation chamber 11. The drive assembly 20 is connected to the shell 10. The drive assembly 20 includes a drive shaft 21. Part of the drive shaft 21 is arranged in the separation chamber 11. The gas-liquid separation assembly has a plurality of blades 31. The first side of each blade 31 is rotatably connected to the shell 10. The second side of each blade 31 is rotatably connected to the drive shaft 21. The rotation of the drive shaft 21 can drive the blade 31 to rotate around the rotation axis of the first side of the blade 31 by a preset angle. Among them, the drive shaft 21 has a first working position in which each blade 31 is driven to rotate by a first angle so that the outer surface of each blade 31 is surrounded by a cylindrical surface, and the drive shaft 21 has a second working position in which each blade 31 is driven to rotate by a second angle so that each blade 31 is arranged at a preset distance.

[0037] Applying the technical solution of this embodiment, the gas-liquid separator includes a drive component 20 and a gas-liquid separation component. The drive component 20 drives the blades 31 of the gas-liquid separation component to rotate at a preset angle, so that the working angle of each blade 31 changes, thereby making the gas-liquid separator have a high gas-liquid separation efficiency under various flow rate conditions, and there is no need to re-select or design the gas-liquid separator for different fuel power systems, thereby improving the versatility of the gas-liquid separator and reducing the gas-liquid separation cost. Combined with the gas-liquid separator of the present application, the problem of poor gas-liquid separation effect of the gas-liquid separator in the prior art is effectively solved. The gas-liquid separator in this embodiment is a gas-liquid separator with variable angle blades, which can ensure that the efficiency of hydrogen and liquid water separation is in the best state at different flow rates. At the same time, the technical solution of this embodiment can not only avoid the flooding problem of the fuel cell stack due to excessive hydrogen humidity, but also achieve the effect of one machine for multiple uses of the gas-liquid separator, which can match fuel cell engine systems of different power levels, and finally achieve the effect of reducing costs, effectively improving the separation efficiency and versatility of the gas-liquid separator.

[0038] like Figure 2 FIG. 2 shows a schematic diagram of the structure when the drive shaft 21 is in the second working position. When the drive shaft 21 is in the second working position, the gas-liquid separator is mainly separated by the baffle (i.e., the blade 31) to achieve a high gas-water separation efficiency for high-velocity gas. Figure 4The schematic diagram of the structure when the drive shaft 21 is located at the first working position is shown. The gas-liquid separator is mainly centrifugal separation to achieve a high gas-water separation efficiency for low flow rate gas. The gas-liquid separator switches between different working positions, so that the gas-liquid separator has a high separation efficiency for various flow rate conditions. In an optional embodiment, there are multiple second working positions. When the drive shaft 21 is located at different multiple second working positions, the angle between the drive shaft 21 and the blade 31 is different, so the baffle separation effect generated by the blade is different, and it has different separation efficiencies.

[0039] Furthermore, the gas-liquid separator also includes a cover body 40 and a liquid storage chamber 50. The cover body 40 is connected to the top of the shell 10. The liquid storage chamber 50 is connected to the bottom of the shell 10. The liquid storage chamber 50 has a accommodating cavity. The accommodating cavity is used to accommodate liquid in the gas-liquid mixture separated by the gas-liquid separation component. Among them, a filter structure 60 is arranged between the liquid storage chamber 50 and the gas-liquid separation component, and the filter structure 60 is connected to the shell 10. This arrangement allows the gas-liquid separator to form a sealed separation space, and no hydrogen leakage will occur. The liquid storage chamber 50 is arranged so that the gas-liquid separator can work uninterruptedly, and the filter structure can effectively prevent the airflow from disturbing the liquid in the liquid storage chamber 50.

[0040] Furthermore, a gas inlet 41 is provided at one end of the side wall of the housing 10 near the cover body 40. A gas outlet 42 is provided at one end of the side wall of the housing 10 near the filter structure 60. A separation flow channel for the gas-liquid mixture is formed between the gas inlet 41, the gas outlet 42, the gas-liquid separation component and the side wall of the housing 10. By optimizing the layout of the gas inlet 41 and the gas outlet 42, sufficient contact between the gas and the gas-liquid separation component is achieved, and at the same time, the initial momentum of the gas is used to drive the gas-liquid separation component to rotate, without the need to set a separate driving energy source.

[0041] Furthermore, the drive assembly 20 further includes a drive motor 22. The output end of the drive motor 22 is connected to the first end of the drive shaft 21, and the second end of the drive shaft 21 extends through the cover 40 toward the filter structure 60. This arrangement can further reduce the size of the gas-liquid separator while ensuring the rotation accuracy of each blade 31.

[0042] Further, the first side of each blade 31 is rotatably connected to the cover body 40 and the filter structure 60 respectively through the hinge 32. The second side of each blade 31 is rotatably connected to the drive shaft 21 through the pull rod 33. The axis of each pull rod 33 is set to form the same angle with the axis of the drive shaft 21.

[0043] In an optional embodiment, the blade group is composed of 6 blades 31 with the same outer diameter. The blade group takes the drive shaft 21 as the axis, and the 6 blade hinges are evenly distributed at an angle of 60°. The drive motor 22 at the upper cover of the gas-liquid separator is connected to the drive shaft 21, and the drive shaft 21 and the blades 31 are connected by a pull rod 33, and the pull rod 33 and the blades 31 and the drive shaft 21 are connected by a hinge structure. Therefore, when the drive motor 22 drives the drive shaft 21 to rotate a certain angle, the blade pull rod 33 will also drive the blade 31 to rotate a certain angle with the blade hinge as the axis, thereby changing the angle of the blade group. The critical angle of the blade group is determined by the specific structure.

[0044] Furthermore, the surface shape of the blade 31 is a curved surface. The blade 31 is set concavely toward the drive shaft 21. When the drive shaft 21 is in the second working position, each blade 31 is set obliquely relative to the drive shaft 21. The side of the blade 31 close to the drive shaft 21 is rotatably connected to the pull rod 33, and the side of the blade 31 away from the drive shaft 21 is provided with a hinge 32. The use of a curved surface shape can further enhance the baffle separation effect of the blade 31. The structural schematic diagram of the drive shaft 21 in the second working position is shown in FIG. Figure 2 As shown, at this time, each blade is tilted relative to the drive shaft 21.

[0045] Furthermore, when the drive shaft 21 is in the second working position, each blade 31 is arranged parallel to the drive shaft 21, and the straight-line distance between the surface of the drive shaft 21 and the edge of the blade 31 is equal to the length of the pull rod 33. Figure 4 As shown, at this time, the blades are parallel to the driving shaft 21, and the separation effect is mainly achieved by the centrifugal force generated by the rotation of the gas-liquid mixture.

[0046] Furthermore, the bottom of the liquid storage chamber 50 is configured as a conical structure, a drainage channel is provided at the bottom of the liquid storage chamber 50 , and a liquid level sensor is provided on the side wall of the liquid storage chamber 50 .

[0047] Furthermore, the filter structure 60 is a filter plate, and a plurality of filter holes are arranged on the filter plate.

[0048] The working process of the gas-liquid separator is described as follows: hydrogen with liquid water (i.e., a gas-liquid mixture) enters the gas-liquid separator from the gas inlet 41, and after separation by the gas-liquid separation component, the dry hydrogen flows out from the gas outlet 42, and the separated liquid water enters the water storage chamber through the mesh plate, and then is discharged from the gas-liquid separator through the drain port.

[0049] According to another specific embodiment of the present invention, a vehicle is provided. The vehicle includes a gas-liquid separator. The gas-liquid separator is the gas-liquid separator in the above embodiment.

[0050] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0051] According to one embodiment of the present invention, an embodiment of a control method for a gas-liquid separator is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0052] The method embodiment can be executed in an electronic device or similar computing device in a vehicle including a memory and a processor. For example, Figure 5 As shown, the electronic device of the vehicle may include one or more processors 102 (the processor may include but is not limited to a central processing unit (CPU), a graphics processing unit (GPU), a digital signal processing (DSP) chip, a microprocessor (MCU), a field programmable logic device (FPGA), a neural network processor (NPU), a tensor processing unit (TPU), an artificial intelligence (AI) type processor, etc.) and a memory 104 for storing data. Optionally, the electronic device of the above-mentioned car may also include a transmission device 106 for communication functions, an input and output device 108, and a display 110. It can be understood by those skilled in the art that Figure 1 The structure shown is for illustration only and does not limit the structure of the electronic device of the vehicle. For example, the electronic device of the vehicle may include more or fewer components than those described in the above structure, or may have a configuration different from that described in the above structure.

[0053] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the control method of the gas-liquid separator in the embodiment of the present invention. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, the control method of the gas-liquid separator described above is realized. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories may be connected to the mobile terminal via a network. Examples of the above-mentioned network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and a combination thereof.

[0054] The transmission device 106 is used to receive or send data via a network. The specific example of the above network may include a wireless network provided by a communication provider of the mobile terminal. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device can be a radio frequency (Radio Frequency, referred to as RF) module, which is used to communicate with the Internet wirelessly.

[0055] The display 110 may be, for example, a touch screen type liquid crystal display (LCD) and a touch display (also referred to as a "touch screen" or a "touch display screen"). The liquid crystal display may enable a user to interact with a user interface of the mobile terminal. In some embodiments, the mobile terminal has a graphical user interface (GUI), and a user may interact with the GUI by finger contact and / or gestures on a touch-sensitive surface, wherein the human-computer interaction functions here may optionally include the following interactions: creating web pages, drawing, word processing, making electronic documents, games, video conferencing, instant messaging, sending and receiving emails, call interfaces, playing digital videos, playing digital music and / or web browsing, etc. The executable instructions for executing the above human-computer interaction functions are configured / stored in a computer program product or a readable storage medium executable by one or more processors.

[0056] This embodiment provides a control method for a gas-liquid separator of an electronic device running on the above vehicle.

[0060] like Figure 7 A flow chart of another specific embodiment of the control method of the gas-liquid separator is shown. Since the angle of the blade group of the gas-liquid separator can be infinitely changed within a variable range, this will complicate the control system. In order to simplify the control model, this control method sets the angle of the blade group to N limited gears for use, and it is necessary to perform a performance test on the gas-liquid separator before use to obtain the separation efficiency Map of the gas-liquid separator under different gas flow rates and different humidity.
