Description

Technical Field

[0001] This utility model belongs to the field of gas-liquid separation technology, specifically relating to a liquid separator, compressor and air conditioning system. Background Technology

[0002] In a traditional distributor structure, a steel pipe is built into the distributor. This pipe typically serves as either a suction pipe or an oil return pipe. One end of the pipe extends towards the top of the distributor, while the other end extends into the bottom and connects to the compressor's suction port. The pipe is fixed within the distributor by a partition, with its upper part suspended in the air, forming a cantilever beam structure. When the compressor operates, it generates periodic suction pulsations. These pulsations are transmitted through the refrigerant gas inside the steel pipe, causing axial and radial vibrations. Due to the length of the steel pipe, this increases the noise of the distributor. Utility Model Content

[0003] This utility model provides a liquid distributor, a compressor, and an air conditioning system, which can solve the technical problem of increasing the noise of the liquid distributor by installing steel pipes in it.

[0004] This utility model provides a liquid separator, which includes an inner shell, an outer shell, and a flow guide; The inner shell is disposed inside the outer shell, and an airflow channel is formed between the outer wall of the inner shell and the inner wall of the outer shell. An exhaust port is provided on the outer shell, and the exhaust port is connected to the airflow channel. The flow guide is installed in the inner shell. The gas-liquid mixture flows on the flow guide and undergoes gas-liquid separation. The separated gas flows into the airflow channel and is discharged from the exhaust port.

[0005] In some embodiments, the outer edge of the guide member is connected to the inner wall of the inner shell. In the axial direction of the inner shell, a gas flow channel is provided on the guide member. The liquid after gas-liquid separation flows on the guide member, and the gas after gas-liquid separation flows into the gas flow channel and the gas flow passage in sequence.

[0006] In some embodiments, the flow guide is spiral-shaped and extends spirally along the axial direction of the inner shell, allowing the gas-liquid mixture to flow spirally downwards on the flow guide.

[0007] In some embodiments, the guide element is a continuous spiral blade, with a connecting hole at the center of each spiral blade, and the gas flow channel is formed between the connecting holes.

[0008] In some embodiments, the inner shell has multiple oil return holes on its side wall, and the liquid after gas-liquid separation flows out from the oil return holes and flows downward along the outer wall of the inner shell.

[0009] In some embodiments, when the flow guide is spiral-shaped, the opening direction of the oil return hole is consistent with the tangential direction of the flow guide.

[0010] In some embodiments, the inner housing and the outer housing are fixed together by circumferentially spaced reinforcing ribs.

[0011] In some embodiments, a filter assembly and a cover are also included. The filter assembly is fastened to the top of the housing, and the cover is installed on the top of the housing and covers the filter assembly. The cover is provided with a gas-liquid mixture inlet pipe. The filter assembly is used for first-stage gas-liquid separation of a portion of the gas-liquid mixture, and the guide is used for second-stage gas-liquid separation of the remaining gas-liquid mixture.

[0013] An air conditioning system includes a distributor, wherein the distributor is the distributor described above.

[0014] The liquid separator, compressor, and air conditioning system provided by this utility model have the following beneficial effects: In this invention, the flow guide achieves gas-liquid separation through its structural features. The inner shell provides space and a guiding path for the flow of the gas-liquid mixture, while the outer shell ensures that the separated gas can be smoothly discharged by forming an airflow channel. The synergistic effect of these three components enables the gas-liquid mixture to complete the separation process efficiently within the separator. The separated gas has higher purity, and the liquid can be smoothly discharged, thereby improving the separation efficiency of the entire separator. The airflow channel is formed by the sandwich between the inner shell and the outer shell, replacing the original steel pipe as the airflow channel. This setting eliminates the conventional partition and steel pipe structure, reducing the noise problem caused by the steel pipe partition. The double-shell structure design also plays a role in noise reduction. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0019] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0020] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used here to describe the spatial positional relationship of a device or feature as shown in the figure with other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation of the device as described in the figure. For example, if a device in the figure is inverted, a device described as "above" or "on top of" other devices or structures will subsequently be positioned as "below" or "under" other devices or structures.

[0021] See also Figures 1 to 7 As shown, according to an embodiment of the present invention, a liquid separator is provided, which includes an inner shell 1, an outer shell 2, and a flow guide 3; the inner shell 1 is disposed inside the outer shell 2, and an airflow channel 4 is formed between the outer wall of the inner shell 1 and the inner wall of the outer shell 2; an exhaust port 201 is provided on the outer shell 2, and the exhaust port 201 is connected to the airflow channel 4; the flow guide 3 is installed in the inner shell 1, and the gas-liquid mixture flows on the flow guide 3 for gas-liquid separation, and the separated gas flows into the airflow channel 4 and is discharged from the exhaust port 201.

[0022] Specifically, the gas-liquid mixture enters the inner shell 1 through the inlet of the separator. At this time, the gas-liquid mixture is in a relatively high-speed and relatively uniform mixing state, with the gas and liquid intertwined and existing in the form of a mixed fluid. The guide element 3 is installed in the inner shell 1. When the gas-liquid mixture flows through the guide element 3, the liquid, due to its higher density, begins to gradually separate from the gas under the action of centrifugal force, gravity, and surface tension of the guide element 3. The liquid particles will adhere to the surface of the guide element 3 and flow downward along the structure of the guide element 3, eventually converging at the bottom of the inner shell 1. The separated gas, guided by the guide element 3, flows upward along the surface of the guide element 3 or through the internal channels of the guide element 3. During this process, some small droplets may remain in the gas, but as the gas flows on the guide element 3, these droplets will also be gradually separated out, further purifying the gas. After being separated by the guide member 3, the gas flows along the upper structure of the guide member 3 or through the gap between the guide member 3 and the inner shell 1 into the airflow channel 4 between the inner shell 1 and the outer shell 2. The gas continues to flow in the airflow channel 4 and finally exits the distributor through the exhaust port 201 on the outer shell 2. In this embodiment, the exhaust port 201 is connected to the compressor's suction port, allowing the gas in the airflow channel 4 to be drawn out.

[0023] In this embodiment, the flow guide 3 is the core component of the gas-liquid separation. It effectively guides the flow direction of the gas-liquid mixture, optimizes the flow path of the mixture, reduces mutual interference between the gas and liquid, and improves separation efficiency. By rationally designing the structure of the flow guide 3, the flow velocity and direction of the gas-liquid mixture can be controlled, making the separation process smoother and avoiding severe turbulence and mixing, thereby improving the separation effect. The flow guide 3 can buffer and guide the flow of the gas-liquid mixture, reducing the impact and vibration generated during the flow. This buffering effect can effectively reduce the vibration and noise inside the separator and improve the operational stability of the separator.

[0024] In this embodiment, the inner shell 1 provides the necessary space for the separation of the gas-liquid mixture, allowing it to flow fully and separate. The internal structure of the inner shell 1 can be customized to adapt to different flow rates and operating conditions. The shape and structure of the inner shell 1 guide the flow direction of the gas-liquid mixture, enabling it to flow smoothly through the guide member 3 and be separated. An airflow channel 4 is formed between the outer wall of the inner shell 1 and the inner wall of the outer shell 2, providing an independent flow space for the separated gas. This structure allows the separated gas to be separated from the liquid, preventing the gas from mixing with the liquid again, thereby improving the purity of the gas and the separation efficiency. The outer shell 2 encapsulates the gas-liquid mixture inside the separator, preventing leakage and ensuring the system's sealing and safety. By rationally setting the shape and structure of the outer shell 2, the flow characteristics of the airflow channel 4 can be optimized, reducing the resistance of the gas during flow and improving the gas discharge efficiency.

[0025] In this embodiment, the flow guide 3 achieves gas-liquid separation through its structural features. The inner shell 1 provides space and a guiding path for the flow of the gas-liquid mixture, while the outer shell 2 ensures that the separated gas can be smoothly discharged by forming an airflow channel 4. The synergistic effect of these three components enables the gas-liquid mixture to complete the separation process efficiently in the separator. The separated gas has higher purity, and the liquid can be smoothly discharged, thereby improving the separation efficiency of the entire separator. The airflow channel 4 is formed by the sandwich between the inner shell 1 and the outer shell 2, replacing the original steel pipe as the airflow channel 4. This setting eliminates the conventional partition and steel pipe structure, reducing the noise problem caused by the steel pipe partition. The double shell structure setting can also play a role in noise reduction.

[0026] In one specific implementation, an exhaust port 201 is located at the bottom of the outer shell 2, and a bent pipe 8 is connected to the exhaust port 201, allowing the gas-liquid mixture to flow in from the top of the inner shell 1. The inner cylinder is disposed inside the outer cylinder, and the two are arranged coaxially or eccentrically to form an annular interlayer space, which is also the airflow channel 4.

[0027] See also Figures 1 to 3As shown, the outer edge of the guide 3 is connected to the inner wall of the inner shell 1. In the axial direction of the inner shell 1, the guide 3 is provided with a gas flow channel 301. The liquid after gas-liquid separation flows on the guide 3, and the gas after gas-liquid separation flows into the gas flow channel 301 and the air flow channel 4 in sequence.

[0028] Specifically, the outer edge of the guide member 3 is connected to the inner wall of the inner shell 1, forming a stable support structure. When the gas-liquid mixture flows through the guide member 3, the liquid, due to its higher density, adheres to the surface of the guide member 3 under the action of centrifugal force, gravity, and surface tension. As the gas-liquid mixture flows, the liquid gradually flows downward along the surface of the guide member 3 and eventually converges at the bottom of the inner shell 1. The separated gas flows upward through the gas flow channel 301 on the guide member 3. The gas flow channel 301 on the guide member 3 provides an independent flow path for the separated gas. The gas enters the upper space of the inner shell 1 through these channels. The separated gas flows into the airflow channel 4 from the upper space of the inner shell 1. Since the exhaust port 201 is located at the bottom of the outer shell 2, the gas and liquid flow downward along the airflow channel 4 and are finally discharged from the separator through the exhaust port 201 on the outer shell 2.

[0029] In this embodiment, the separated gas enters the upper space of the inner shell 1 through the gas flow channel 301 on the guide member 3, and then flows into the airflow channel 4, avoiding re-mixing of gas and liquid and ensuring the purity of the gas. The design of the inner shell 1 and the outer shell 2 optimizes the flow path of the gas-liquid mixture, reduces flow resistance and turbulence, and makes the flow of the gas-liquid mixture in the separator more stable. The design of the gas flow channel 301 and the airflow channel 4 ensures that the separated gas can smoothly enter the airflow channel 4 from the guide member 3 and be discharged from the separator through the exhaust port 201, avoiding blockage or backflow of gas during the flow process. The outer edge of the guide member 3 is connected to the inner wall of the inner shell 1 to form a stable support structure, preventing the guide member 3 from being displaced or deformed under the impact of the gas-liquid mixture, ensuring the operational stability of the separator. The guide member 3 can buffer the flow of the gas-liquid mixture, reducing the impact and vibration during the flow process. The structural design of the inner shell 1 and the outer shell 2 can further disperse and absorb vibration energy, reduce the transmission of vibration to the outside, and reduce the vibration and noise during the operation of the separator. The gas flow channel 301 on the guide 3 and the airflow channel 4 between the inner shell 1 and the outer shell 2 work together to ensure that the separated gas and liquid can flow along their respective paths, avoiding the re-mixing of gas and liquid and improving the efficiency of gas-liquid separation.

[0030] See also Figures 1 to 5As shown, the guide member 3 is spiral in shape and extends spirally along the axial direction of the inner shell 1. The gas-liquid mixture flows spirally downward on the guide member 3, and the separated gas flows upward from the gas flow channel 301. Since the exhaust port 201 is located at the bottom of the outer shell 2, the separated gas flows into the air flow channel 4 from the gas flow channel 301 and flows downward. That is, the flow direction of the gas in the gas flow channel 301 and the air flow channel 4 is opposite.

[0031] Specifically, the guide element 3 is spiral-shaped and extends spirally along the axial direction of the inner shell 1. After the gas-liquid mixture enters the guide element 3, it flows downward along the spiral path. This spiral flow path increases the residence time and contact area of ​​the gas-liquid mixture on the guide element 3, making the gas-liquid separation more complete. During the spiral flow process, due to its higher density, the liquid will gradually move to the outer wall of the guide element 3 and adhere to the surface of the guide element 3 under the action of centrifugal force. As the gas-liquid mixture flows downward in a spiral, the liquid gradually converges downward along the surface of the guide element 3 and eventually flows into the bottom of the inner shell 1; while the gas phase tends to flow in the direction of the center of the inner cylinder. Therefore, after gas-liquid separation, the gas phase will move upward from the middle position, and the separated gas will flow upward through the gas flow channel 301 on the guide 3. The gas flow channel 301 on the guide 3 provides an independent flow path for the separated gas. The gas enters the upper space of the inner shell 1 through these channels. An airflow channel 4 is formed between the outer wall of the inner shell 1 and the inner wall of the outer shell 2. Since the exhaust port 201 is located at the bottom of the outer shell 2, the separated gas flows into the airflow channel 4 from the upper space of the inner shell 1 and then flows downward along the airflow channel 4. Finally, it is discharged from the separator through the exhaust port 201 at the bottom of the outer shell 2.

[0032] In this embodiment, the spiral guide 3 extends spirally along the inner shell 1, greatly increasing the contact area between the gas-liquid mixture and the guide 3. This means that the gas-liquid mixture has more opportunities to interact with the surface of the guide 3 during the flow process, thereby achieving more complete separation. Due to the spiral flow path, the liquid moves to the outer wall of the guide 3 and adheres to the surface under the action of centrifugal force. This centrifugal separation mechanism makes it easier for liquid particles to separate from the gas and flow downward along the surface of the guide 3, thereby improving the separation efficiency. The long path length of the spiral guide 3 increases the residence time of the gas-liquid mixture in the inner shell 1, which provides more time for gas-liquid separation and further improves the separation efficiency. The spiral guide 3 can guide the gas-liquid mixture to flow smoothly along the spiral path, reducing turbulence and resistance during the flow process. This flow method makes the gas-liquid mixture flow more smoothly in the separator and reduces energy loss. Since the exhaust port 201 is located at the bottom of the outer shell 2, the separated gas flows upward in the gas flow channel 301 and then flows into the air flow channel 4 and flows downward. This reverse flow setting allows the gas to further separate any possible residual liquid particles during the flow process, ensuring that the discharged gas is purer. The spiral guide 3 can buffer the flow of the gas-liquid mixture and reduce the impact and vibration during the flow process. The encapsulation of the inner shell 1 and the outer shell 2 can further disperse and absorb vibration energy and reduce the transmission of vibration to the outside, thereby reducing the vibration and noise during the operation of the separator.

[0033] See also Figures 1 to 5 As shown, the flow guide 3 is a continuous spiral blade, with a connecting hole 302 at the center of each spiral blade, forming a gas flow channel 301 between the connecting holes 302. The outer edge of the spiral blade is connected to the inner wall of the inner shell 1, forming a stable support structure to ensure that the flow guide 3 will not be displaced or deformed under the impact of the gas-liquid mixture. In other embodiments, the flow guide 3 is a segmented spiral structure, and similarly, a connecting hole 302 is provided at the center of the segmented spiral structure.

[0034] In this embodiment, the spiral blades are arranged so that the gas-liquid mixture flows downward along the spiral path. Under the action of centrifugal force, the liquid moves towards the outer wall of the spiral blades and adheres to the surface, flowing downward along the spiral blades and finally converging at the bottom of the inner shell 1. The surface structure of the spiral blades can effectively guide the liquid flow, allowing the liquid to gradually converge during the flow process, avoiding local accumulation of liquid on the surface of the guide 3, and ensuring that the liquid can be smoothly discharged from the distributor. The connecting hole 302 at the center of a single spiral blade forms a gas flow channel 301. The separated gas flows upward through these connecting holes 302 and enters the upper space of the inner shell 1. Since the exhaust port 201 is located at the bottom of the outer shell 2, the gas flows from the upper space of the inner shell 1 into the airflow channel 4 and flows downward, finally being discharged from the distributor through the exhaust port 201. This reverse flow arrangement further ensures the purity of the gas and avoids the re-mixing of gas and liquid. The structure of the spiral blades can guide the gas-liquid mixture to flow smoothly along the spiral path, reducing turbulence and resistance during the flow process. This flow method makes the gas-liquid mixture flow more smoothly in the separator and reduces energy loss. The gas flow channel 301 formed by the connecting hole 302 provides an independent and smooth flow path for the separated gas, avoiding blockage or backflow of gas during the flow process.

[0035] See also Figures 1 to 7 As shown, multiple oil return holes 101 are provided on the side wall of the inner housing 1. The liquid after gas-liquid separation flows out from the oil return holes 101 and flows downward along the outer wall of the inner housing 1. It falls from the bottom of the inner housing 1 to the bottom of the distributor and enters the bend pipe 8 to achieve smooth oil return from the compressor.

[0036] Specifically, the guide member 3 is spiral-shaped and extends axially along the inner shell 1. After the gas-liquid mixture enters the guide member 3, it flows downward along the spiral path. During the spiral flow, due to its higher density, the liquid gradually moves towards the outer wall of the guide member 3 and adheres to its surface under the action of centrifugal force. As the gas-liquid mixture flows downward in a spiral, the liquid gradually converges downward along the surface of the guide member 3. Multiple oil return holes 101 are provided on the side wall of the inner shell 1. These oil return holes 101 provide an independent outflow path for the separated liquid. The liquid flows out of the inner shell 1 through the oil return holes 101 and enters the space between the inner shell 1 and the outer shell 2. The liquid flowing out of the oil return holes 101 flows downward along the outer wall of the inner shell 1 and finally converges at the bottom of the distributor, entering the bend pipe 8 to achieve smooth oil return from the compressor.

[0037] In this embodiment, the oil return hole 101 provides an independent outflow channel for the separated liquid, allowing it to flow smoothly out of the inner shell 1 and preventing liquid accumulation within the inner shell 1. This helps ensure that the liquid inside the separator can be discharged in a timely manner, reducing the residence time of the liquid inside the separator. After flowing out through the oil return hole 101, the liquid flows downward along the outer wall of the inner shell 1 and eventually converges at the bottom of the separator. This design prevents the liquid from flowing back into the gas channel, ensuring the purity of the gas in the gas channel and further improving the gas-liquid separation effect. The uniform distribution of the oil return holes 101 allows the liquid to flow out of the inner shell 1 evenly, avoiding local liquid accumulation and reducing the unevenness that may occur during the separation process, further improving the uniformity of gas-liquid separation. After being discharged through the oil return hole 101, the liquid can promptly converge at the bottom of the separator, reducing the residence time of the liquid inside the separator and preventing excessive liquid level fluctuations due to excessive liquid accumulation. This helps the system maintain a stable operating state and reduces system failures or instability that may be caused by liquid level fluctuations. It is worth noting that lubricating oil is an essential component in applications such as refrigeration systems. Through the oil return hole 101, the separated liquid can smoothly exit the distributor and enter the system's oil return line, ensuring that the lubricating oil can return to critical components such as the compressor in a timely manner. This helps maintain the system's lubrication effect, ensures the normal operation of components such as the compressor, and extends the system's service life. Without the oil return hole 101, lubricating oil may accumulate in the distributor, preventing it from returning to the system in a timely manner. This would not only reduce the system's lubrication effect but may also increase the dilution effect of the lubricating oil on the refrigerant, affecting the system's refrigeration performance. The oil return hole 101 effectively avoids this problem, ensuring the circulation of lubricating oil and the normal operation of the system.

[0038] See also Figures 1 to 7 As shown, when the guide member 3 is spiral, the opening direction of the oil return hole 101 is consistent with the tangential direction of the guide member 3. Specifically, the oil return hole 101 is a teardrop shape arranged horizontally, and the large end of the oil return hole 101 extends in the spiral direction.

[0039] In this embodiment, the opening direction of the oil return hole 101 is consistent with the tangential direction of the guide member 3, so that the liquid flows along the tangential direction when leaving the guide member 3. This directionality allows the liquid to flow more smoothly from the surface of the guide member 3 into the oil return hole 101, avoiding the accumulation and backflow of liquid on the surface of the guide member 3. When the liquid enters the oil return hole 101 along the tangential direction, it can reduce the turbulence and resistance when the liquid enters the oil return hole 101, making the liquid flow more stable and further optimizing the liquid discharge path. The spiral guide member 3 itself separates the liquid through centrifugal force. The tangential direction setting of the oil return hole 101 allows the liquid to make better use of centrifugal force when leaving the guide member 3, further enhancing the liquid separation effect. After the liquid enters the oil return hole 101 along the tangential direction, it can more effectively prevent the liquid from flowing back into the gas channel 301, further improving the efficiency of gas-liquid separation and the purity of the gas.

[0040] See also Figures 1 to 6 As shown, the inner shell 1 and the outer shell 2 are fixed together by reinforcing ribs 5 distributed circumferentially. The arrangement of the reinforcing ribs 5 does not affect the flow of gas in the airflow channel 4.

[0041] In this embodiment, the reinforcing rib 5 provides additional support between the inner shell 1 and the outer shell 2, effectively dispersing and transferring stress between them. This arrangement allows the distributor to maintain higher structural strength when subjected to internal fluid pressure and external environmental pressure. The reinforcing rib 5 prevents deformation of the inner shell 1 and outer shell 2 during operation due to pressure differences or mechanical impacts. Its role is particularly important under high-pressure or high-flow conditions, ensuring long-term stable operation of the distributor. The reinforcing rib 5 effectively buffers vibrations between the inner shell 1 and outer shell 2, reducing vibrations and noise caused by gas-liquid mixture flow or mechanical impacts. This buffering effect improves the smoothness of the distributor's operation and reduces operating noise. By rationally setting the distribution and stiffness of the reinforcing rib 5, resonance phenomena that may occur during operation can be effectively reduced. Resonance can lead to structural fatigue and damage; the reinforcing rib 5 effectively avoids this problem.

[0042] See also Figures 1 to 7As shown, it also includes a filter assembly 6 and a cover 7. The filter assembly 6 is fastened to the top of the outer shell 2, and the cover 7 is installed on the top of the outer shell 2 and covers the filter assembly 6. The cover 7 is provided with a gas-liquid mixture inlet pipe. The filter assembly 6 is used for the first-stage gas-liquid separation of a portion of the gas-liquid mixture, and the guide member 3 is used for the second-stage gas-liquid separation of the remaining gas-liquid mixture. In one specific embodiment, the axial length of the inner shell 1 is less than the axial length of the outer shell 2. After the filter assembly 6 is fastened to the outer shell 2, there is still a certain distance between the filter assembly 6 and the top outer wall of the inner shell 1. After the gas-liquid mixture is separated by the filter assembly 6, the gas can flow smoothly into the airflow channel 4. In other embodiments, an air outlet can also be opened on the side wall of the inner shell 1, and the air outlet is connected to the airflow channel 4. Similarly, the gas separated by the guide member 3 flows smoothly into the airflow channel 4 after flowing into the upper part of the inner shell 1 through the gas flow channel 301.

[0043] Specifically, the gas-liquid mixture enters the separator through the gas-liquid mixture inlet pipe on the cover 7. The inlet pipe introduces the gas-liquid mixture above the filter assembly 6, preparing for the first stage of gas-liquid separation. After entering the filter assembly 6, the flow rate of the gas-liquid mixture is rapidly reduced due to the obstruction of the filter. This reduction in flow rate makes the relative motion between the gas and liquid in the mixture more pronounced, creating preliminary conditions for subsequent gas-liquid separation. The filter assembly 6 consists of multiple layers of filter screens, which can perform preliminary separation of the gas-liquid mixture. When liquid particles pass through the filter screen, due to their higher density, they adhere to the filter screen, forming droplets and gradually converging. The liquid adhering to the filter screen gradually converges and flows downward along the surface of the filter screen, eventually flowing into the inner shell 1. The gas separated by the filter assembly 6 enters the inner shell 1 through the pores of the filter screen, where some of the gas undergoes further gas-liquid separation, and some flows into the airflow channel 4. The gas-liquid mixture after initial separation by filter assembly 6, or the remaining gas-liquid mixture that filter assembly 6 failed to separate, enters the inner shell 1. At this point, the liquid particles in the mixture have been significantly reduced, but may still contain a small number of tiny droplets. The guide member 3 is spiral-shaped and extends along the axial direction of the inner shell 1. After the gas-liquid mixture enters the guide member 3, it flows downward along the spiral path. During the spiral flow, the liquid particles, due to their higher density, will gradually move towards the outer wall of the guide member 3 and adhere to the surface under the action of centrifugal force. As the gas-liquid mixture spirals downward, the liquid gradually converges downward along the surface of the guide member 3 and eventually flows into the bottom of the inner shell 1. The separated gas flows upward through the gas flow channel 301 on the guide member 3 and enters the upper space of the inner shell 1. The separated gas enters the upper space of the inner shell 1 through the gas flow channel 301 on the guide member 3, then flows into the airflow channel 4 and flows downward, finally exiting the separator through the exhaust port 201 at the bottom of the outer shell 2. The separated liquid gradually converges as it flows on the surface of the guide 3, eventually flowing into the bottom of the inner shell 1. The liquid flows out through the oil return hole 101 on the side wall of the inner shell 1, flows down along the outer wall of the inner shell 1, and finally converges at the bottom of the distributor and is discharged from the distributor.

[0044] In this embodiment, the filter assembly 6 performs preliminary separation of the gas-liquid mixture entering the separator, mainly removing larger liquid particles. The multi-layer structure of the filter effectively intercepts liquid particles, causing them to adhere to the filter and converge and flow out, thereby reducing the amount of droplets entering the inner housing 1. The gas-liquid mixture after preliminary separation by the filter assembly 6 enters the inner housing 1, where the guide element 3 performs fine separation of the remaining gas-liquid mixture. The guide element 3 further separates fine droplets through a spiral path and centrifugal force, ensuring the purity of the gas. This two-stage separation setup makes the separation process more thorough. The filter assembly 6 and the guide element 3 complement each other and work together to significantly improve the efficiency and effect of gas-liquid separation. The filter assembly 6 can initially decelerate and distribute the gas-liquid mixture, reduce the fluid impact force entering the inner shell 1, and reduce turbulence and resistance. The guide component 3 guides the gas-liquid mixture to flow smoothly through a spiral path, further reducing turbulence and resistance during the flow process. This arrangement makes the flow of the gas-liquid mixture in the separator more stable and improves the separation efficiency. The synergistic effect of the filter assembly 6 and the guide component 3 optimizes the flow path of the gas-liquid mixture, allowing the gas to pass smoothly through the two-stage separation structure and finally be discharged from the exhaust port 201.
