Description

Technical Field

[0001] This application relates to the field of gas drying technology, and in particular to an automotive air drying separator and vehicle. Background Technology

[0002] Air humidity control in the passenger and cargo compartments of a vehicle is crucial. Excessive moisture content not only causes windows to fog up, affecting driver visibility, but also accelerates the corrosion of internal metal components, triggers electrical system malfunctions, and may breed bacteria, affecting the health of passengers or damaging transported goods. Therefore, dehumidification and drying of the air introduced into or recirculated within the vehicle are typically necessary. Automotive air dryers, as the core device for achieving this purpose, are widely installed in the vehicle's air system.

[0003] Currently, automotive air dryers typically consist of a base and a housing, which together form a drying chamber. The base has an air inlet and an exhaust outlet. The drying chamber contains an exhaust pipe and a drying element. Compressed air enters the drying chamber through the air inlet, and the drying element absorbs moisture, achieving drying. The dried air is then discharged from the exhaust outlet through the exhaust pipe. To accommodate the internal structure and guide gas flow, existing air dryers typically use a U-shaped tube as the core exhaust pipe, with the desiccant surrounding or bundled around it. However, the U-shaped tube requires bending and is quite long, increasing material consumption and resulting in higher manufacturing costs. Furthermore, the U-shaped tube occupies considerable internal space, easily interfering with surrounding structures during component assembly, making the installation and positioning of internal components very difficult, and increasing production assembly time and labor costs. Summary of the Invention

[0004] To address the problems of complex internal piping structure, inconvenient installation, and high manufacturing cost of existing automotive air dryer separators, this application provides an automotive air dryer separator.

[0005] Firstly, the vehicle air drying separator provided in this application adopts the following technical solution: An automotive air dryer separator for use in a vehicle, the automotive air dryer separator comprising: A base and a housing, the housing being disposed on the base to form a drying chamber together with the base, the base being provided with an air inlet and an air outlet communicating with the drying chamber; A drying assembly is disposed within the drying chamber. The drying assembly includes an exhaust straight pipe and a drying element. The drying element is disposed on the exhaust straight pipe and is used to dry the gas flowing into the drying chamber. The inlet of the exhaust straight pipe is located within the drying chamber, and the outlet is located at the exhaust port to discharge the dried gas.

[0006] By adopting the above technical solution and replacing the U-shaped tube with a straight exhaust pipe, on the one hand, the straight pipe eliminates the need for bending, simplifying the manufacturing process. Furthermore, the straight pipe is significantly shorter than the U-shaped tube, drastically reducing material consumption and effectively lowering raw material and processing costs. On the other hand, the straight structure of the exhaust pipe makes its positioning and assembly within the drying chamber much simpler and faster. Unlike the U-shaped tube, which requires simultaneous alignment of two ports with the base interface, installation is completed simply by aligning the outlet of the exhaust pipe with the exhaust port, significantly shortening production and assembly time and reducing labor costs. In addition, the compact structure of the straight pipe occupies less space within the drying chamber, allowing for a more rational spatial layout and optimizing the gas flow path, thus improving overall drying efficiency.

[0007] Optionally, the drying assembly further includes a filter element disposed at the inlet of the exhaust straight pipe.

[0008] By adopting the above technical solution, it is possible to effectively prevent desiccant particles or dust from entering the exhaust straight pipe with the drying gas and being discharged into the vehicle's air circuit system. This protects downstream pneumatic components from wear and blockage by particulate matter, helps extend the service life of various components in the air circuit system, and improves the reliability and stability of the vehicle's air circuit system operation.

[0009] Optionally, the filter element includes a filter frame and a filter screen. The filter frame is located at the inlet of the exhaust straight pipe, and a filter port is provided on the periphery of the filter frame. The filter screen is located at the filter port.

[0010] By adopting the above technical solution, gas can enter from the side and exit from the end, which helps to improve the filtration efficiency and filtration capacity of the filter element. The peripherally distributed filter ports provide a larger effective filtration area, making the filter element less prone to clogging due to particulate matter accumulation after prolonged use, thus extending its service life and maintenance cycle. The filter frame, as the supporting skeleton of the filter screen, ensures the morphological stability of the filter screen under airflow impact, preventing deformation or damage due to air pressure fluctuations, and ensuring the continuous reliability of the filtration effect.

[0011] Optionally, the filter frame is inserted into the inlet of the exhaust straight pipe.

[0012] By adopting the above technical solutions, the installation and disassembly of filter components can be greatly simplified, the assembly difficulty and assembly time on the production line can be reduced, and production efficiency can be improved.

[0013] Optionally, the drying assembly further includes a flow guide disposed on the exhaust straight pipe, the flow guide being spaced apart from the base, for guiding the gas flowing into the drying chamber to the periphery of the drying chamber.

[0014] By adopting the above technical solution, the flow path and distribution of gas in the drying chamber can be effectively optimized, so that the gas entering from the inlet can be evenly dispersed to the peripheral area of ​​the drying chamber. This avoids the short-circuit phenomenon where the gas flows directly through the exhaust pipe axis without fully contacting the drying components, which helps to improve the utilization rate of the drying components and the overall drying efficiency. It also enables the gas to form a reasonable flow field distribution in the drying chamber, so that the drying components in each area can participate in the moisture adsorption work evenly, avoiding the uneven phenomenon of local drying components being oversaturated while other areas of drying components are not fully utilized. This helps to extend the overall service life and regeneration cycle of the drying components.

[0015] Optionally, the air guide has opposing windward and leeward sides, with the windward side tapering away from the leeward side.

[0016] By adopting the above technical solution, the airflow on the surface of the guide is made smoother, which helps to reduce the pressure loss and flow resistance when the airflow passes through the guide and maintain a high gas flow efficiency in the drying chamber. At the same time, the airflow can be evenly dispersed to the surrounding areas, avoiding the phenomenon that the airflow concentrates on a certain area of ​​the guide surface and forms a flow dead zone in other areas. This allows the gas to be more evenly distributed to the surrounding areas of the drying chamber, which helps to improve the uniform utilization rate of the drying component and the overall drying performance.

[0017] Optionally, the exhaust pipe includes an exhaust main pipe and an exhaust sleeve. The outlet of the exhaust main pipe is located at the exhaust port, and the exhaust sleeve is fitted onto the exhaust main pipe to define a circulation channel together with the exhaust main pipe, so that some of the filtered gas can flow back into the drying chamber.

[0018] By adopting the above technical solution, some of the dried gas can be circulated back into the drying chamber. This allows the drying element to be continuously partially regenerated during normal operation, which helps to significantly extend the effective working time and service life of the drying element, reduce the replacement frequency and maintenance cost of the drying element, and also plays a certain role in regulating the airflow distribution in the drying chamber, promoting the uniform flow of gas in the drying chamber, and further improving the overall drying efficiency and drying uniformity.

[0019] Optionally, the drying element is fixed to the exhaust straight pipe by a clamp structure.

[0020] By adopting the above technical solution, it can be ensured that the drying element remains in the predetermined position during use and will not loosen due to vibration or airflow impact, thus guaranteeing the stability and reliability of the dryer separator. At the same time, the clamp structure is easy to assemble and disassemble; simply loosening or tightening the clamp strap completes the removal or installation of the drying element, significantly improving the convenience of drying element replacement and maintenance, shortening maintenance time, and reducing maintenance costs.

[0021] Optionally, the drying element includes a drying package filled with a molecular sieve desiccant.

[0022] By adopting the above technical solution, the excellent adsorption performance of molecular sieve desiccant can be fully utilized, enabling the dryer to efficiently remove moisture from the air and ensure that the dryness of the output gas meets the usage requirements. At the same time, the molecular sieve desiccant can be integrated into an independent modular unit, making the installation, disassembly and replacement of the drying components simple and quick. There is no need to fill and clean the bulk desiccant in the drying chamber, which helps to improve maintenance efficiency.

[0023] Secondly, the vehicle provided in this application adopts the following technical solution: A vehicle includes an automotive air dryer separator, the automotive air dryer separator comprising: A base and a housing, the housing being disposed on the base to form a drying chamber together with the base, the base being provided with an air inlet and an air outlet communicating with the drying chamber; A drying assembly is disposed within the drying chamber. The drying assembly includes an exhaust straight pipe and a drying element. The drying element is disposed on the exhaust straight pipe and is used to dry the gas flowing into the drying chamber. The inlet of the exhaust straight pipe is located within the drying chamber, and the outlet is located at the exhaust port to discharge the dried gas.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. This application significantly reduces the consumption of pipe materials and eliminates the cumbersome bending process by using a straight exhaust pipe instead of a U-shaped pipe, effectively reducing raw material and manufacturing costs. At the same time, the straight exhaust structure allows the internal drying components to be installed by simply aligning the outlet in one direction, greatly simplifying the assembly process and reducing manual labor time. Furthermore, the compact straight pipe space layout further optimizes the airflow path in the drying chamber and improves the overall drying efficiency of the machine. 2. By installing a guide with a tapered front side on the exhaust straight pipe, this application can greatly optimize the initial airflow distribution in the drying chamber. With extremely low flow resistance, the concentrated upward airflow is smoothly and evenly dispersed and guided to the peripheral area of ​​the drying chamber, avoiding short-circuiting caused by the airflow going straight out from the center and the generation of local dead zones. This allows the drying components in each area to participate in moisture adsorption evenly, which helps to improve the overall utilization rate of the drying medium. 3. This application utilizes the internal circulation channel constructed by the exhaust pipe and exhaust sleeve to guide a portion of the dehydrated high-quality dry gas back into the drying chamber, thereby achieving continuous micro-purging and online partial regeneration of the drying components. This helps to extend the effective working time and dehumidification life of the molecular sieve. Combined with the tool-free quick-release clamp structure and modular package design, it can significantly reduce the frequency of maintenance and replacement costs of the separator.

[0027] The following is in conjunction with the appendix Figure 1 - Appendix Figure 7 This application will be described in further detail below.

[0028] In one embodiment of this application, please refer to Figure 1 and Figure 2An automotive air dryer separator 100 is used in a vehicle. The automotive air dryer separator 100 includes a base 11, a housing 12, and a drying assembly 2. The housing 12 is disposed on the base 11 to form a drying chamber 13 together with the base 11. The base 11 is provided with an air inlet 111 and an exhaust outlet 112 communicating with the drying chamber 13. The drying assembly 2 is disposed in the drying chamber 13 and includes an exhaust straight pipe 21 and a drying element 22. The drying element 22 is disposed on the exhaust straight pipe 21 to dry the gas flowing into the drying chamber 13. The inlet of the exhaust straight pipe 21 is located in the drying chamber 13, and the outlet is located at the exhaust outlet 112 to discharge the dried gas.

[0029] Understandably, the base 11, as the fundamental load-bearing component of the entire separator, is typically made of metal and possesses sufficient structural strength to withstand internal air pressure and external installation loads. The base 11 has an inlet 111 and an outlet 112. The inlet 111 is used to introduce compressed air to be dried, and the outlet 112 is used to discharge the dried clean gas. Both the inlet 111 and outlet 112 are connected to the drying chamber 13. The housing 12, mounted on the base 11, can be cylindrical or dome-shaped, and together with the base 11, forms a closed drying chamber 13, which is the working space for gas drying. The drying assembly 2 is located within the drying chamber 13. The drying assembly 2 includes an exhaust straight pipe 21 and a drying element 22. The exhaust straight pipe 21 is a straight tube. The inlet of the exhaust straight pipe 21 is inside the drying chamber 13 to receive the dried gas, and the outlet of the exhaust straight pipe 21 is located at the outlet 112 on the base 11 to discharge the dried gas to the external gas path. A drying element 22 is mounted on the exhaust straight pipe 21 to adsorb and dehumidify the gas flowing into the drying chamber 13. Further, compressed air enters the drying chamber 13 through the air inlet 111 on the base 11. The gas flows within the drying chamber 13 and comes into full contact with the drying element 22 mounted on the exhaust straight pipe 21. The desiccant in the drying element 22 adsorbs moisture from the gas, significantly reducing its humidity. The dried gas then enters the exhaust straight pipe 21 from its inlet and flows directly along the straight pipe path to its outlet, finally exiting through the exhaust port 112 on the base 11 into the vehicle's air system. Because the exhaust straight pipe 21 adopts a straight pipe structure, the gas flows in a straight line. Compared to a U-shaped pipe where the gas needs to pass through a bend to change its direction, the airflow resistance inside the straight pipe is lower, resulting in smoother gas flow and improved exhaust efficiency. Meanwhile, the straight structure of the exhaust straight pipe 21 significantly reduces its space occupation in the drying chamber 13. Unlike the U-shaped pipe, it does not occupy a large amount of lateral space due to the presence of the bend section, thus leaving more ample installation space for the arrangement of the drying component 22 and other internal components, reducing the possibility of interference between components during assembly.

[0030] In this embodiment, by using a straight exhaust pipe 21 instead of a U-shaped pipe, two advantages are achieved. First, the straight pipe eliminates the need for bending, simplifying the manufacturing process. Furthermore, the pipe length is significantly shorter than that of a U-shaped pipe, drastically reducing material consumption and effectively lowering raw material and processing costs. Second, the straight structure of the exhaust pipe 21 makes its positioning and assembly within the drying chamber 13 much simpler and faster. Unlike a U-shaped pipe, it does not require simultaneous alignment of both ports with the interfaces on the base 11. Installation is completed simply by aligning the outlet of the exhaust pipe 21 with the exhaust port 112, significantly shortening production and assembly time and reducing labor costs. In addition, the compact structure of the straight pipe occupies little internal space within the drying chamber 13, resulting in a more rational spatial layout. This optimizes the gas flow path within the drying chamber 13, improving overall drying efficiency.

[0031] In one embodiment of this application, please refer to Figure 2 and Figure 4 The drying assembly 2 also includes a filter element 23, which is located at the inlet of the exhaust straight pipe 21. The filter element 23 intercepts and filters desiccant particles, dust, or other fine impurities that may be carried in the gas. Further, compressed air enters the drying chamber 13 through the inlet 111 and comes into contact with the dryer element 22 to complete the drying process. The dried gas, carrying desiccant particles that may have detached from the dryer element 22 or residual dust from the drying chamber 13, flows towards the inlet of the exhaust straight pipe 21. At this point, the filter element 23 intercepts and filters the gas, trapping solid particles and impurities on its surface or inside, allowing only clean, dried gas to pass through the filter element 23 into the exhaust straight pipe 21 and finally exit from the exhaust port 112. Thus, by incorporating the filter element 23, desiccant particles or dust can be effectively prevented from entering the exhaust straight pipe 21 with the dried gas and being discharged into the vehicle's air system. This protects downstream pneumatic components from wear and blockage by particulate matter, helps extend the service life of various components in the air system, and improves the reliability and stability of the vehicle's air system operation.

[0032] In one embodiment of this application, please refer to [the relevant documentation]. Figure 2 and Figure 4The filter element 23 includes a filter frame 231 and a filter screen. The filter frame 231 is located at the inlet of the exhaust straight pipe 21. Filter ports 2311 are provided on the periphery of the filter frame 231, and the filter screen is located at the filter ports 2311, allowing gas flowing into the filter element 23 to enter from the side and exit from the end. The filter frame 231 is a frame with a certain structural strength, which can be made of metal or engineering plastic. Located at the inlet of the exhaust straight pipe 21, the filter frame 231 serves to support and position the filter screen. The filter ports 2311 are through holes or openings on the sidewall of the filter frame 231, and one or more can be provided, distributed circumferentially along the filter frame 231. The filter screen is located at the filter ports 2311 to filter the gas passing through them. The bottom of the filter frame 231 can be a closed structure to guide gas from the peripheral filter ports 2311 into the interior of the filter frame 231. Furthermore, when the dried gas flows from the drying chamber 13 to the filter element 23, since the filter port 2311 is located on the periphery of the filter frame 231, the gas enters the internal space of the filter frame 231 after being filtered by the filter screen from the side of the filter frame 231, and then enters the exhaust straight pipe 21 from the end of the filter frame 231. This achieves a side-in, end-out flow pattern, causing the flow direction of the gas entering the filter element 23 to form a certain angle with the flow direction of the gas entering the exhaust straight pipe 21. Heavier particles carried in the gas are difficult to follow the airflow change due to inertia when the flow direction changes, thus being effectively separated and trapped on the outside of the filter screen, improving the filtration efficiency. At the same time, the filter ports 2311 are distributed on the periphery of the filter frame 231, allowing gas to enter the filter element 23 from multiple directions simultaneously, effectively increasing the filtration area, reducing the airflow velocity per unit area, and reducing airflow resistance. Thus, by placing the filter ports 2311 on the periphery of the filter frame 231, allowing the gas to enter from the side and exit from the end, it helps to improve the filtration efficiency and filtration capacity of the filter element 23. The peripherally distributed filter ports 2311 provide a large effective filtration area, making the filter element 23 less prone to clogging due to particulate matter accumulation after prolonged use, thus extending its service life and maintenance cycle. The filter frame 231, as the supporting skeleton of the filter screen, ensures the morphological stability of the filter screen under airflow impact, preventing deformation or damage due to air pressure fluctuations, and ensuring the continuous reliability of the filtration effect.

[0033] Furthermore, there are various ways to install the filter frame 231. In one embodiment of this application, please refer to... Figure 2 and Figure 5The filter frame 231 is inserted into the inlet of the exhaust straight pipe 21. The filter frame 231 is connected to the inlet of the exhaust straight pipe 21 via an insertion method. During assembly, simply align the insertion part of the filter frame 231 with the inlet of the exhaust straight pipe 21 and apply a certain axial thrust to insert the filter frame 231 into place. No bolts, nuts, or other fasteners are needed, nor are special tools required for tightening or locking. The entire assembly process is quick and easy. Similarly, when it is necessary to disassemble the filter element 23 for cleaning or replacement, simply pull the filter frame 231 out of the inlet of the exhaust straight pipe 21 axially. The disassembly process is equally convenient and quick. Thus, the insertion connection between the filter frame 231 and the exhaust branch pipe greatly simplifies the installation and disassembly of the filter element 23, reduces assembly difficulty and time on the production line, and helps improve production efficiency.

[0034] In one embodiment of this application, please refer to Figure 2 and Figure 5 The drying assembly 2 also includes a guide member 24 disposed on the exhaust straight pipe 21. The guide member 24 is spaced apart from the base 11 and is used to guide the gas flowing into the drying chamber 13 to the periphery of the drying chamber 13. The guide member 24 is disposed on the exhaust straight pipe 21, located within the internal space of the drying chamber 13, and is typically positioned on the side of the exhaust straight pipe 21 closer to the base 11. A certain distance is maintained between the guide member 24 and the base 11, and this distance constitutes the initial flow area of ​​the gas after it enters the drying chamber 13 from the inlet 111. The function of the guide member 24 is to guide the gas flowing into the drying chamber 13 from the inlet 111 to the periphery of the drying chamber 13, that is, to guide the gas to flow towards the outer area of ​​the drying chamber 13. Furthermore, after the gas enters the drying chamber 13 through the air inlet 111 on the base 11, it first reaches the space between the guide member 24 and the base 11. Due to the obstruction and guidance effect of the guide member 24, the gas cannot flow directly along the axial direction of the exhaust straight pipe 21, but is forced to change its flow direction and diffuse along the surface of the guide member 24 towards the periphery of the drying chamber 13. After reaching the periphery of the drying chamber 13, the gas flows upward along the outer area of ​​the drying chamber 13, and in this process, it comes into full contact with the drying members 22 distributed on the exhaust straight pipe 21, achieving efficient moisture adsorption and drying treatment. This airflow path that diffuses from the center to the periphery makes the gas diffuse more evenly throughout the drying chamber 13, and the residence time in the drying chamber 13 is longer, the contact area with the drying members 22 is larger, and the drying effect is more thorough. The guide member 24 is spaced apart from the base 11, so that the gas at the air inlet 111 can smoothly enter the drying chamber 13 without blocking the air intake channel due to the guide member 24 directly contacting the base 11.

[0035] In this embodiment, by setting a guide 24 spaced apart from the base 11, the flow path and distribution of gas in the drying chamber 13 can be effectively optimized, so that the gas entering from the air inlet 111 can be evenly dispersed to the peripheral area of ​​the drying chamber 13. This can avoid the short-circuiting phenomenon where the gas flows directly through the exhaust pipe 21 without fully contacting the drying element 22, which helps to improve the utilization rate of the drying element 22 and the overall drying efficiency. It can also make the gas form a reasonable flow field distribution in the drying chamber 13, so that the drying elements 22 in each area can participate in the moisture adsorption work evenly, avoiding the uneven phenomenon where the local drying elements 22 are oversaturated while the drying elements 22 in other areas are not fully utilized, which helps to extend the overall service life and regeneration cycle of the drying elements 22.

[0036] In one embodiment of this application, please refer to [the relevant documentation]. Figure 2The air guide 24 has a windward side 2411 and a leeward side 2421, with the windward side 2411 tapering away from the leeward side 2421. The windward side 2411 is the surface facing the air inlet 111 (i.e., the side facing the base 11), and the leeward side 2421 is the surface away from the air inlet 111 (i.e., the side away from the base 11). The windward side 2411 tapering away from the leeward side 2421 means that its outer contour gradually decreases from the end closer to the leeward side 2421 to the end farther away, forming a cone-shaped, conical, or arc-shaped protrusion. This causes the cross-sectional area of ​​the windward side 2411 of the air guide 24 to gradually decrease away from the leeward side 2421, with the tip or narrow end of the windward side 2411 facing the base 11 and the wide end or base facing the leeward side 2421. Furthermore, when compressed air enters the drying chamber 13 from the inlet 111 and impacts the windward side 2411 of the guide 24, due to the tapered shape of the windward side 2411, the airflow first contacts the tip or narrow end region of the windward side 2411, and then slides and diffuses outward along the slope of the tapered surface. The tapered shape of the windward side 2411 provides a smooth guiding effect for the airflow. The airflow does not experience a drastic change in direction when flowing along the slope, but gradually changes its flow direction under the guidance of the tapered surface, smoothly transitioning from axial flow to radial flow, and is finally guided to the periphery of the drying chamber 13. This smooth airflow transition process can effectively reduce the separation and eddy current phenomena of the airflow on the surface of the guide 24, and reduce the degree of airflow turbulence and energy loss. Thus, the windward side 2411 adopts a tapered design, which not only makes the airflow on the surface of the guide 24 smoother, but also helps to reduce the pressure loss and flow resistance when the airflow passes through the guide 24, which is conducive to maintaining a high gas flow efficiency in the drying chamber 13. It can also evenly disperse the airflow to the surrounding areas, avoiding the phenomenon that the airflow concentrates and impacts in a certain area of ​​the surface of the guide 24, forming a flow dead zone in other areas. This allows the gas to be more evenly distributed to the surrounding areas of the drying chamber 13, which helps to improve the uniform utilization rate of the drying component 22 and the overall drying performance.

[0037] Furthermore, in one embodiment of this application, please refer to [reference needed]. Figure 2 and Figure 3The guide member 24 includes a guide body 242 and a guide portion 241, which together form a water collection cavity 2422. The windward side 2411 includes the side of the guide portion 241 facing away from the guide body 242. The guide portion 241 and the guide body 242 are spaced apart to form an inlet annular gap, allowing droplets to flow into the water collection cavity 2422. The guide portion 241 is located on the windward side 2411 of the guide body 242, i.e., the side facing the base 11, and its side facing away from the guide body 242 constitutes the aforementioned windward side 2411. The guide portion 241 and the guide body 242 are spaced apart, forming an inlet annular gap that extends circumferentially along the guide member 24. The water collection chamber 2422 is a closed space formed between the guide body 242 and the guide section 241, used to collect and temporarily store liquid water droplets separated from the gas. Further, when moisture-containing air enters the drying chamber 13 through the air inlet 111, it impacts the windward side 2411 surface of the guide section 241. Some of the moisture in the gas condenses on the surface of the guide section 241 to form droplets, or the liquid water droplets originally carried in the gas are trapped after impacting the surface of the guide section 241. These droplets flow towards the periphery along the surface of the guide section 241 under the action of the airflow. When the droplets reach the liquid inlet annular gap between the guide section 241 and the guide body 242, they flow into the water collection chamber 2422 for collection and temporary storage. Thus, by setting up a water collection cavity 2422 formed by the guide body 242 and the guide section 241, and by using the liquid inlet annular gap between the guide section 241 and the guide body 242 to collect the separated droplets, some of the liquid moisture can be effectively separated and collected before the gas enters the dryer 22. This significantly reduces the dehumidification burden on the dryer 22, helping to extend its service life and regeneration cycle. Furthermore, by setting up the water collection cavity 2422, the separated liquid water will not re-mix into the airflow, avoiding the problem of rapid saturation and failure of the dryer 22 due to repeated contact with liquid water. The liquid inlet annular gap also ensures that droplets in all directions around the guide section 24 can be effectively collected, improving the liquid water separation efficiency and significantly reducing the liquid water content in the gas entering the dryer 22, thereby improving the overall drying effect and the performance of the dryer separator.

[0038] In one embodiment of this application, please refer to [the relevant documentation]. Figure 3The liquid inlet slit 2423 is inclined, with the inclination direction being inclined towards the leeward side 2421 in the direction towards the periphery of the guide member 24. That is, the liquid inlet slit does not extend in a direction perpendicular to the surface of the guide member 24, but is inclined at a certain angle relative to the axis or surface normal of the guide member 24. Specifically, when viewed from the center of the guide member 24 towards the periphery, the direction of the liquid inlet slit 2423 gradually shifts towards the leeward side 2421 (i.e., the side away from the base 11), so that the inlet end of the liquid inlet slit is located on the windward side 2411, and the outlet end extends into the water collection cavity 2422 in the direction towards the leeward side 2421, forming a liquid introduction channel that is inclined from the outside to the inside and from the windward side 2411 to the leeward side 2421. When a droplet flows along the windward side 2411 of the guide section 241 towards the periphery and reaches the inlet of the liquid inlet annular slit, the liquid inlet slit 2423 is inclined towards the leeward side 2421. Under the action of surface tension, the droplet can naturally flow into the water collection cavity 2422 along the inclined slit. The inclination direction is consistent with the natural flow trend of the droplet under gravity, which is conducive to the smooth introduction of the droplet. More importantly, the inclination of the liquid inlet slit 2423 towards the leeward side 2421 makes the direction of the slit form a certain angle with the main impact direction of the airflow on the windward side 2411. The airflow is difficult to directly pour into the water collection cavity 2422 along the inclined slit, thus effectively preventing the high-speed airflow from disturbing the liquid already collected in the water collection cavity 2422. Thus, by adopting the liquid inlet slit 2423, the flow path of droplets from the surface of the guide 24 into the water collection chamber 2422 can be optimized, making the droplet introduction process smoother and more efficient, reducing the retention and accumulation of droplets at the inlet of the liquid inlet slit 2423, and effectively enhancing the liquid retention capacity of the water collection chamber 2422, preventing the collected liquid water from overflowing back from the liquid inlet slit 2423 and re-entering the drying chamber 13 under the impact of airflow, thus ensuring the stability and reliability of the liquid water separation effect.

[0039] In one embodiment of this application, please refer to the following: Figures 5 to 7The exhaust straight pipe 21 includes an exhaust main pipe 211 and an exhaust sleeve 212. The outlet of the exhaust main pipe 211 is located at the exhaust port 112. The exhaust sleeve 212 is fitted onto the exhaust main pipe 211, together defining a circulation channel 213 so that some of the filtered gas can flow back into the drying chamber 13. The exhaust main pipe 211 is the core pipe of the exhaust straight pipe 21, and its outlet is located at the exhaust port 112 on the base 11, used to discharge the dried gas to the external gas system. The exhaust sleeve 212 is fitted onto the outside of the exhaust main pipe 211, meaning that the inner diameter of the exhaust sleeve 212 is larger than the outer diameter of the exhaust main pipe 211. The exhaust sleeve 212 coaxially or approximately coaxially covers the periphery of the exhaust main pipe 211. The annular gap between the exhaust sleeve 212 and the exhaust main pipe 211 together defines the circulation channel 213, which is an annular channel extending axially along the exhaust main pipe 211. The function of the circulation channel 213 is to allow a portion of the filtered gas to flow back from the exhaust pipe 211 to the drying chamber 13, achieving gas recycling. Specifically, the dried gas enters the exhaust pipe 211 through the inlet of the exhaust straight pipe 21, and a portion flows along the exhaust pipe 211 and is discharged to the external gas path through the exhaust port 112. Simultaneously, another portion of the dried and filtered clean gas flows back to the drying chamber 13 through the circulation channel 213 between the exhaust pipe 211 and the exhaust sleeve 212. The clean, dried gas flowing back into the drying chamber 13 mixes with the moisture in the drying chamber 13, reducing the overall humidity of the gas within the drying chamber 13. Furthermore, as the dried return gas passes through the moisture-adsorbed drying element 22, it carries away some of the adsorbed moisture from the drying element 22, effectively regenerating it. This allows the drying element 22 to continuously undergo partial regeneration during operation, helping to slow down its saturation rate.

[0040] In this embodiment, by forming a circulation channel 213, some of the dried gas can be circulated back into the drying chamber 13. This allows the drying element 22 to be continuously partially regenerated during normal operation, which helps to significantly extend the effective working time and service life of the drying element 22, reduce the replacement frequency and maintenance cost of the drying element 22, and also plays a certain role in regulating the airflow distribution in the drying chamber 13, promoting the uniform flow of gas in the drying chamber 13, and further improving the overall drying efficiency and drying uniformity.

[0041] In one embodiment of this application, please refer to Figure 2 and Figure 5The leeward side 2421 is provided with a groove 2424, and the end of the circulation channel 213 away from the inlet of the exhaust main pipe 211 extends into the groove 2424. The groove 2424 is a groove-shaped structure formed by an inward indentation on the surface of the leeward side 2421, and its depth and width are designed according to the size of the circulation channel 213 and the airflow rate. The end of the circulation channel 213 away from the inlet of the exhaust main pipe 211 extends into the groove 2424, meaning that the upper end (the end away from the base 11) of the annular circulation channel 213 formed between the exhaust sleeve 212 and the exhaust main pipe 211 extends into the groove 2424 of the leeward side 2421 of the guide member 24, so that the outlet of the circulation channel 213 is located in the internal space of the groove 2424. Furthermore, the clean, dry gas returning through the circulation channel 213 flows out from the upper end of the circulation channel 213 and first enters the groove 2424 on the leeward side 2421 of the guide member 24. The groove 2424 serves to converge and buffer the returning gas. After the returning gas undergoes preliminary velocity adjustment and direction distribution within the groove 2424, it then diffuses evenly into the internal space of the drying chamber 13 from the edge or opening of the groove 2424. The presence of the groove 2424 ensures that the outlet of the circulation channel 213 is not directly exposed to the main airflow area of ​​the drying chamber 13, avoiding direct collision and interference between the returning gas and the main airflow entering from the inlet 111, and reducing airflow turbulence. Thus, by setting the groove 2424 and extending the circulation channel 213 into the groove 2424, the transition process of the return gas from the circulation channel 213 into the drying chamber 13 is optimized. This allows the return gas to be buffered and evenly distributed within the groove 2424 before diffusing to various areas of the drying chamber 13. This prevents the return gas from directly impacting the drying element 22 in the form of a high-speed jet or violently colliding with the main airflow, thereby improving the uniformity and stability of the airflow distribution within the drying chamber 13. In one embodiment of this application, the drying component 22 is fixed to the exhaust straight pipe 21 by a clamp structure 25. The clamp structure 25 can be of various forms, such as bolt-fastened clamps, spring clamps, or quick-release clamps, and can be made of metal or plastic. The drying component 22 is fixed to the outer wall of the exhaust straight pipe 21 by the clamp structure 25, and one or more clamp structures 25 can be provided along the axial direction of the exhaust straight pipe 21 to firmly fix the drying component 22 in a predetermined position. Thus, by using the clamp structure 25 to fix the drying component 22 to the exhaust straight pipe 21, it can be ensured that the drying component 22 remains in the predetermined position during use and will not loosen due to vibration or airflow impact, ensuring the stability and reliability of the dryer separator. At the same time, the clamp structure 25 is easy to install and remove; simply loosening or tightening the clamp strap completes the removal or installation of the drying component 22, which can greatly improve the convenience of replacing and maintaining the drying component 22, shorten maintenance time, and reduce maintenance costs.

[0042] In one embodiment of this application, please refer to Figure 2 and Figure 5 The dryer 22 is detachably installed on the clamp structure 25. When the dryer 22 becomes saturated with desiccant after prolonged use and needs replacement, the operator simply opens or loosens the clamp structure 25 to remove the worn-out dryer 22 from the exhaust straight pipe 21, places the new dryer 22 in the corresponding position on the exhaust straight pipe 21, and then tightens the clamp structure 25 again to complete the replacement. The entire replacement process does not require disassembly of other components of the dryer separator or the use of complex special tools, making the operation simple and quick. This detachable connection method not only makes the replacement of the dryer 22 more convenient, significantly reducing maintenance time, but also allows users to replace only the worn-out dryer 22 while retaining other components such as the clamp structure 25 for continued use, avoiding unnecessary component waste and reducing long-term maintenance and parts consumption costs.

[0043] In one embodiment of this application, the drying component 22 includes a drying package filled with molecular sieve desiccant. The drying package is a drying unit that encapsulates desiccant within a breathable packaging material. The outer packaging material is typically made of materials with good breathability, such as non-woven fabric, breathable cotton cloth, mesh fabric, or microporous membrane. These materials allow gas to freely permeate and fully contact the internal desiccant while simultaneously encapsulating the desiccant particles to prevent them from scattering. Molecular sieve desiccant is a synthetic aluminosilicate material with a uniform microporous structure. Commonly used types include 3A, 4A, 5A, and 13X. Its micropore size is uniform and can be selected as needed, allowing selective adsorption of water molecules of specific sizes. It has advantages such as large adsorption capacity, fast adsorption speed, and maintaining high adsorption capacity even in low humidity environments. Furthermore, the drying bag is installed on the exhaust straight pipe 21 via a clamp structure 25 or other fixing method. When compressed air containing moisture flows in the drying chamber 13 and passes through the drying bag, the gas permeates through the outer breathable packaging material of the drying bag and enters the interior of the drying bag, making full contact with the molecular sieve desiccant filled inside. The microporous structure of the molecular sieve desiccant has a strong adsorption effect on water molecules. Water molecules in the gas are selectively adsorbed in the micropores of the molecular sieve, while other gas molecules continue to flow through the drying bag, thereby achieving efficient drying of the gas. In this way, by using a drying bag filled with molecular sieve desiccant, the excellent adsorption performance of the molecular sieve desiccant can be fully utilized, enabling the dryer separator to efficiently remove moisture from the air and ensure that the dryness of the output gas meets the usage requirements. At the same time, the molecular sieve desiccant can be integrated into an independent modular unit, making the installation, disassembly, and replacement of the drying component 22 simple and quick, eliminating the need for filling and cleaning of bulk desiccant in the drying chamber 13, which helps to improve maintenance efficiency.
