Description

Technical Field

[0001] This invention relates to the field of gas purification technology, and more particularly to gas nano-purifiers. Background Technology

[0002] In industrial automation, precision manufacturing, and the operation of pneumatic equipment, the quality of high-pressure air directly affects the accuracy and lifespan of end effectors. Raw compressed air typically contains a large amount of condensate, oil, and solid particulate dust. If these impurities are not effectively removed, they can lead to pipe corrosion, jamming of pneumatic components, seal failure, or product contamination. Therefore, air source processing systems usually require drying and purification equipment to remove moisture and dust from the air.

[0003] Existing gas purification equipment typically adopts a split structure, with each component connected in series through numerous external pipelines. The split components occupy a large space, resulting in low overall integration and making it inconvenient to install and maintain in confined spaces. The overall structure is loose, requiring each unit to be fixed separately during transportation and on-site installation, which is cumbersome. The paths between the purification components and gas storage devices are long and the connections are not tight enough, which can easily cause severe pressure fluctuations during gas flow, resulting in poor airflow stability, significant vibration and noise, and even gas leakage. Summary of the Invention

[0004] To address the aforementioned shortcomings, this invention proposes a gas nano-purifier.

[0005] The technical solution adopted in this invention is a gas nano-purifier, comprising:

[0006] Mounting base;

[0007] A gas storage chamber, installed on the mounting base, is used to store clean gas. The upper side wall of the gas storage chamber extends upward to form a mounting plate, and a gas passage hole is opened in the middle of the mounting plate.

[0008] A gas-liquid separator, installed on the mounting plate, is used for the initial purification of the gas to be cleaned.

[0009] An adsorption tower, installed on the mounting plate, is used for secondary purification of the gas to be cleaned.

[0010] The gas to be cleaned flows sequentially through the gas-water separator and the adsorption tower before entering the gas storage chamber; the adsorption tower and the gas storage chamber are connected by an exhaust pipe.

[0011] Preferably, the gas-water separator includes a separator inlet and a swirl assembly; the swirl assembly includes nested swirl blades and a guide tube, the swirl blades include an outer ring and an inner ring arranged coaxially, and several blades, the several blades being spaced apart between the outer ring and the inner ring, the blades forming an acute / obtuse angle with the axial direction of the outer ring; the separator inlet is located above the swirl blades; the guide tube is a cylindrical structure and passes through the center of the inner ring, the interior of the guide tube including several gas channels extending along its axial direction.

[0012] Preferably, the gas-water separator further includes a primary filter element and a separator outlet. The internal cavity of the primary filter element is sealed and connected to the top outlet of the guide tube. The gas in the internal cavity of the primary filter element passes through the wall of the primary filter element and is discharged through the separator outlet.

[0013] Preferably, the adsorption tower comprises:

[0014] The outer tube has a first air outlet on its wall;

[0015] An inner tube is coaxially arranged with and housed within the outer tube. The inner tube is divided into an interconnected air inlet section, an adsorption section, and a dust removal section from bottom to top. The air inlet section has a tower air inlet on its pipe wall. The adsorption section is filled with an adsorbent, and a first filter and a second filter are respectively provided between the adsorption section and the air inlet section, and between the adsorption section and the dust removal section. At least a portion of the sidewall of the dust removal section is configured as a filter layer.

[0016] In the purification process, the high-pressure gas to be treated enters the inner tube from the air inlet of the tower body, then flows from bottom to top through the adsorption section and the dust removal section, then radially passes through the filter layer and enters the annular gap between the inner tube and the outer tube, and finally exits from the first air outlet of the outer tube.

[0017] Preferably, the second filter screen is slidably disposed at the upper end of the adsorption section along the axial direction of the inner tube; the adsorption tower further includes an elastic compensation mechanism, the elastic compensation mechanism comprising:

[0018] A clamping component is installed within the dust removal section;

[0019] The elastic preload member abuts against the clamping member and the second filter screen at both ends along its elastic force.

[0020] Preferably, the outer periphery of the clamping member is provided with an external thread, and the inner wall of the dust removal section is provided with an internal thread that mates with the external thread. The clamping member changes its axial position in the dust removal section by rotating the thread.

[0021] Preferably, a second air outlet is provided at the lower end of the air inlet section; the adsorption tower further includes a regeneration gas chamber, which is connected to the outer pipe body; under purification conditions, after the gas in the dust removal section passes through the filter layer, part of it is discharged from the first air outlet and part of it enters the regeneration gas chamber; under regeneration conditions, the clean gas in the regeneration gas chamber enters the outer pipe body and passes through the filter layer, the second filter screen, the adsorbent and the first filter screen in sequence, and is discharged from the second air outlet.

[0022] Preferably, it further includes a sludge collection chamber, which is fixed on the mounting base and has a sludge inlet; the gas-liquid separator has a first sludge outlet, and the adsorption tower has a second sludge outlet, with the sludge inlet connected to the first and second sludge outlets respectively; the sludge collection chamber is provided with an inclined baffle, which has a first end and a second end opposite to each other, the first end being higher than the second end in the direction of gravity, and the first end being located below the sludge inlet.

[0023] Preferably, the device includes two vent valves and two adsorption towers, with the two adsorption towers symmetrically mounted on the mounting plate and the two vent valves installed between the two adsorption towers. The two adsorption towers are respectively a first adsorption tower and a second adsorption tower, and the two vent valves are respectively a first vent valve and a second vent valve. One end of the first vent valve is connected to the gas-liquid separator, and the other end is used to connect to the inlet end of the first or second adsorption tower. One end of the second vent valve is connected to the gas storage chamber, and the other end is used to connect to the outlet end of the first or second adsorption tower.

[0024] Preferably, the drain valve includes:

[0025] The valve body has one common interface and two switching interfaces;

[0026] A pair of symmetrically arranged valve seats are fixed in the valve body, and each valve seat forms a valve cavity. One end of each valve cavity is connected to the common interface, and the other end is connected to the corresponding switching interface.

[0027] A valve core is slidably disposed between the two valve chambers. The valve core moves under the action of the pressure difference at both ends to alternately close one of the switching ports while opening the other switching port.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. This invention achieves an integrated layout with the gas storage chamber as the base by extending the upper sidewall of the gas storage chamber upward to form a mounting plate, and centrally mounting the vortex assembly of the gas-water separator, the primary filter element, and the adsorption tower on the same side of the mounting plate. The exhaust pipe passes through a horizontally opened gas passage hole on the mounting plate, allowing the connecting pipeline to be housed within the solid structure of the mounting plate, avoiding the pipeline being suspended outside the equipment and significantly reducing the risk of pipeline damage from external impacts or pulling. The guiding effect of the gas passage hole limits the exhaust pipe path to the shortest straight distance, reducing pipeline length and the number of bends, thereby reducing gas flow resistance and leakage risks, resulting in better airflow stability and reduced vibration and noise. Simultaneously, the entire unit forms a side-mounted module; during transportation and on-site installation, only the mounting base needs to be fixed, eliminating the need to adjust the position of each unit separately, greatly simplifying the installation operation and improving the overall integrity and space utilization of the equipment.

[0030] 2. This invention incorporates nested vortex blades and a flow guide tube in the gas-liquid separator. The inclined blades of the vortex blades generate swirling centrifugal separation to remove large droplets. The axial gas channel of the flow guide tube, in conjunction with the flow guide ribs, organizes the airflow into multiple stable axial airflows. Fine droplets are separated by gravity settling and inertial collision. The final product undergoes fine filtration through a primary filter element to remove particulate impurities and gaseous oil and oil vapor, forming a series structure of two-stage centrifugal separation and one-stage fine filtration, which significantly improves gas-liquid separation efficiency and filtration accuracy.

[0031] 3. The adsorption tower adopts a tube-in-tube structure with an outer and inner tube body nested coaxially. Gas radially passes through the filter layer into the annular gap, resulting in a large effective filtration area, low gas resistance, and uniform pressure distribution on the filter layer surface, avoiding localized perforation failure. The elastic compensation mechanism eliminates gaps caused by adsorbent contraction in real time through elastic pre-tightening components and a sliding second filter screen, preventing adsorbent agitation and solving the airflow short-circuit problem caused by the tunnel effect. This ensures the long-term stability of the output gas dew point and extends the adsorbent's service life.

[0032] 4. This invention employs a valve module consisting of two valves and two adsorption towers symmetrically arranged on a mounting plate. The valves are located between the two towers. The first valve controls the intake gas distribution, and the second valve controls the exhaust gas collection. Both valves utilize the fluid's own pressure difference to drive the valve core movement, achieving automatic switching between alternating adsorption and regeneration of the two towers without external electrical control. The valve seat of the valve adopts a combined structure of locking element, limiting sleeve, and baffle seat. The valve core consists of a connecting rod and a composite baffle assembly. Combined with the inclined design of the annular sealing seat and the boss-groove fitting structure of the baffle assembly and the nut, high sealing performance, low friction loss, and high-frequency stable commutation are achieved.

[0033] 5. The sludge collection bin separates the gas and liquid in the regeneration waste gas through inclined baffles. Combined with the first and second baffles, exhaust grille, and sound-absorbing cotton, this achieves multi-stage settling, noise reduction, and clean emission of the waste gas, avoiding secondary pollution. The entire system has a compact structure, simple control logic, and reliable operation, making it suitable for industrial applications with high requirements for gas pressure stability and gas cleanliness.

[0062] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0063] In one embodiment, see Figure 1-2 The gas nano-purifier includes a mounting base 600, a gas storage chamber 500, a gas-water separator 400, and an adsorption tower 100.

[0064] Mounting base 600 is made of welded or cast metal sheet, such as carbon steel or stainless steel. Mounting base 600 has a flat or frame structure and serves to support other components of the equipment and provide a stable foundation. Vibration-damping feet can be installed under mounting base 600 to reduce vibrations transmitted to the ground during equipment operation.

[0065] The gas storage chamber 500 is fixedly installed on the mounting base 600 and is used to store purified gas. The gas storage chamber 500 is a sealed pressure vessel, which can be made of carbon steel or stainless steel, and its shape can be cylindrical, spherical, or rectangular to adapt to different installation spaces and volume requirements. The upper side wall of the gas storage chamber 500 extends upward to form a mounting plate 510, which is integrally formed with the shell of the gas storage chamber 500 or fixedly connected by welding. A gas passage hole is opened in the middle of the mounting plate 510, which extends horizontally through the mounting plate 510 for the subsequent exhaust pipe 520 and various electrical wires to pass through.

[0066] The gas-liquid separator 400 is installed on one side of the mounting plate 510 and is used for the initial purification of the gas to be cleaned. The gas-liquid separator 400 can be a centrifugal or filter type, and its shell is usually made of aluminum alloy, stainless steel or carbon steel, with swirl vanes or filter elements inside. The bottom of the gas-liquid separator 400 has a drain port for discharging the separated liquid water and oil.

[0067] The adsorption tower 100 is also installed on one side of the mounting plate 510 for further purification of the gas after the first purification. The adsorption tower 100 can be a vertical cylindrical structure, filled with an adsorbent such as activated alumina or molecular sieve. Preferably, the adsorption tower 100 and the gas-liquid separator 400 are installed on the same side of the mounting plate 510.

[0068] The gas to be cleaned flows sequentially through the gas-liquid separator 400 and the adsorption tower 100 before entering the gas storage chamber 500. Specifically, the gas to be cleaned first enters the gas-liquid separator 400 from an external gas source. After gas-liquid separation and preliminary filtration by the primary filter element in the gas-liquid separator 400, the gas enters the adsorption tower 100 through a connecting pipeline. Inside the adsorption tower 100, the gas comes into full contact with the adsorbent, and moisture and residual impurities are adsorbed and removed, forming clean gas. After being discharged from the outlet of the adsorption tower 100, the clean gas enters the gas storage chamber 500 through an exhaust pipe 520.

[0069] The adsorption tower 100 and the gas storage chamber 500 are connected by an exhaust pipe 520. The exhaust pipe 520 can be made of metal, with one end connected to the outlet of the adsorption tower 100 and the other end connected to the inlet of the gas storage chamber 500. The exhaust pipe 520 passes through a gas passage hole in the middle of the mounting plate 510. Since the gas passage hole runs horizontally through the mounting plate 510, and both the gas-liquid separator 400 and the adsorption tower 100 are mounted on the same side of the mounting plate 510, the exhaust pipe 520, after exiting the outlet of the adsorption tower 100, passes directly through the gas passage hole into the gas storage chamber 500 in a short straight line, without any unnecessary bends or detours. A gap can be maintained between the inner wall of the gas passage hole and the outer wall of the exhaust pipe 520 to facilitate installation and disassembly. Alternatively, a rubber sleeve or sealing ring can be installed inside the gas passage hole to prevent direct contact and wear between the exhaust pipe 520 and the mounting plate 510.

[0070] This embodiment achieves an integrated layout with the gas storage chamber 500 as a lateral base by extending the upper sidewall of the gas storage chamber 500 upward to form a mounting plate 510, and centrally mounting the gas-liquid separator 400 and the adsorption tower 100 on the same side of the mounting plate 510. The exhaust pipe 520 passes through a horizontally opened gas passage hole on the mounting plate 510, allowing the connecting pipeline to be housed within the solid structure of the mounting plate 510. This avoids the pipeline being suspended outside the equipment, significantly reducing the risk of damage from external impacts or pulling. Due to the guiding and constraining effect of the gas passage hole, the path of the exhaust pipe 520 is limited to the shortest straight distance, reducing pipeline length and the number of bends, thereby reducing gas flow resistance and leakage risks, resulting in better airflow stability and reduced vibration and noise. Meanwhile, the main functional components such as the gas-liquid separator 400 and the adsorption tower 100 are all integrated on the same side of the mounting plate 510, forming a side-mounted module. During transportation and on-site installation, only the mounting base 600 needs to be fixed, without the need to adjust the position of each unit separately, which greatly simplifies the installation operation and improves the overall integrity and space utilization of the equipment.

[0071] In a more specific embodiment, the gas storage chamber 500 adopts a pressure tank structure, and the material can be selected from materials with excellent pressure resistance such as carbon steel with an anti-corrosion lining, stainless steel, or aluminum alloy. The bottom is fixed to the mounting base 600 by multiple sets of support legs, providing sufficient storage space for clean gas. The left or right side of the upper part of the gas storage chamber 500 extends vertically upward to form a mounting plate 510. The mounting plate 510 is a vertical rectangular plate structure, and the material can be selected from metal plates with high structural strength and good corrosion resistance such as carbon steel or stainless steel. The plate surface is arranged perpendicular to the axis of the gas storage chamber 500, and the lower edge of the mounting plate 510 is completely attached to the outer wall of the gas storage chamber 500. It is fixedly connected by full welding or integral casting to form an integrated rigid load-bearing structure.

[0072] Reinforcing ribs can be provided at both ends of the mounting plate 510 to improve its structural strength. Furthermore, components with corresponding functions can be added to the mounting plate according to the actual equipment requirements. The gas-liquid separator 400 and the adsorption tower 100 are located on the side of the mounting plate 510 away from the gas storage chamber 500, facilitating the installation of structures such as the sludge collection chamber 230 below the gas-liquid separator 400 and the adsorption tower 100.

[0073] In one embodiment, see Figure 3-4 The gas-liquid separator 400 includes a lower chamber and an upper chamber. Both chambers can be made of corrosion-resistant metal materials such as aluminum alloy or stainless steel, which also possess certain pressure-bearing properties. They are formed through stamping, casting, or welding processes and are assembled as a single unit using a sealed connection structure to ensure the airtightness of the gas-liquid separator 400 and meet the requirements for high-pressure gas purification. A separator inlet 410 is provided on the outer wall of the lower chamber. The high-pressure gas to be cleaned enters the lower chamber through the separator inlet 410, undergoes gas-liquid separation in the lower chamber, and then enters the upper chamber for filtration. After filtration in the upper chamber, the gas is discharged through the separator outlet 440 on the outer wall of the upper chamber to the adsorption tower for subsequent drying and other steps, achieving directional flow and staged filtration of the gas within the gas-liquid separator 400.

[0074] Specifically, a vane assembly 420 is installed in the lower cavity, and the separator inlet 410 is connected to the vane assembly 420. The separator inlet 410 can be in the form of a pipe connector, with threads machined on its inner wall for connection to an external air intake pipe. The material of the separator inlet 410 is the same as that of the housing, typically aluminum alloy or stainless steel.

[0075] The swirl assembly 420 includes nested swirl blades 421 and a guide tube 422. Each swirl blade 421 consists of a coaxially arranged outer ring, an inner ring, and several blades. Both the outer and inner rings are annular structures, which can be made from sheet metal through stamping, injection molding, or precision casting, using materials such as plastic, stainless steel, or aluminum alloy. Several blades are spaced apart between the outer and inner rings, with each blade's ends fixedly connected to the inner wall of the outer ring and the outer wall of the inner ring, respectively. The blades can be thin-plate structures, with their planes forming an acute or obtuse angle with the axial direction of the outer ring, i.e., the blades are inclined relative to the axial direction. The specific angle of the blades can be optimized according to the requirements of gas flow rate and separation efficiency, typically between 10 and 85 degrees. The blades are made of the same material as the outer and inner rings, and the three can be integrally cast or fixed by welding or riveting.

[0076] The guide tube 422 is a cylindrical structure, inserted through the center of the inner ring of the rotor 421. The axis of the guide tube 422 coincides with the axis of the rotor 421. Inside the guide tube 422, several gas channels extending axially are provided. These gas channels are formed by guide ribs distributed radially along the tube. The guide ribs can be integrally molded from the same material as the tube to ensure structural integrity and impact resistance. The gas channels extend axially through the upper and lower ends of the tube, forming a continuous flow channel for directional upward gas flow.

[0077] The separator inlet 410 is located above the swirl vane 421. After the clean gas enters the gas-water separator 400 through the separator inlet 410, it passes through the swirl vane 421 from top to bottom through the gaps between multiple vanes. Under the guidance of the vanes, a high-speed swirling flow is formed. After the initial centrifugal separation is completed, the gas enters the interior of the cylinder from the lower end of the guide tube 422, flows upward along the axially extended gas channel, and finally exits from the upper end of the guide tube 422 into the upper filter structure.

[0078] The gas-liquid separator 400 also includes a primary filter element 430, which is located in the upper cavity and can be a cylindrical structure. The internal cavity of the primary filter element 430 is sealed to the top outlet of the guide tube 422. A sealing gasket or sealing ring can be installed between them to prevent gas leakage from the connection gap and ensure that all gas discharged through the guide tube 422 enters the internal cavity of the primary filter element 430. The wall of the primary filter element 430 is made of filter material, such as pleated filter paper, rolled filter paper, sintered metal mesh, or polyester fiber. Under pressure, the gas in the internal cavity passes through the wall of the primary filter element 430. Residual liquid droplets and solid particles in the gas are intercepted inside the filter element. Clean gas is collected from the outside of the filter element and discharged through the separator outlet 440 to the subsequent adsorption tower. The filtered impurities fall down under gravity, and the impurities are periodically emptied by controlling the opening and closing of the drain valve below.

[0079] After the gas undergoes cyclone separation via the guide tube 422, it enters the internal cavity of the primary filter element 430. Under pressure, it radially penetrates the filter element wall, where the filter media traps and filters residual fine droplets and solid impurities, completing secondary filtration and purification. The filtered clean gas collects in the upper cavity and finally exits the gas-water separator 400 through the separator outlet 440 on the outer wall of the upper cavity. The separator outlet 440 can use the same pipe joint structure as the separator inlet 410, or it can be set as a flange interface according to pipeline connection requirements. Its material is the same as that of the upper cavity shell to ensure the sealing and stability of the high-pressure gas discharge.

[0080] During operation, the gas to be cleaned enters the gas-liquid separator 400 through the separator inlet 410 and first flows into the vortex assembly 420. The gas first enters the blade area of ​​the vortex 421, where the inclined blades force the gas to swirl, using centrifugal force to throw large liquid droplets and solid particles entrained in the gas towards the shell wall, achieving preliminary gas-liquid separation. Subsequently, the gas flows into the guide tube 422 and flows upward through the axial gas channel inside the guide tube 422. During the upward axial flow, fine droplets fall under the action of gravity, achieving further separation of fine droplets. The primary filter element 430 further traps the fine impurities remaining after separation by the vortex assembly 420, and the two work together to ensure the purification effect.

[0081] This embodiment forms a series structure of two-stage separation and one-stage fine filtration by placing the swirl vane assembly 420 in the lower cavity and the primary filter element 430 in the upper cavity. The inclined blades of the swirl vane 421 generate swirling centrifugal separation to remove large particles; the axial gas channel of the guide tube 422, in conjunction with the guide ribs, organizes the swirling gas into multiple stable axial airflows, further utilizing gravity settling and inertial collision to separate fine droplets. The primary filter element 430 provides fine filtration to ensure the cleanliness of the output gas. The guide ribs not only separate multiple independent channels but also enhance the structural strength of the guide tube 422, preventing deformation under high-pressure airflow impact. The overall structure is compact, the airflow path is clear, and the separation efficiency is high, making it suitable for industrial applications with high gas cleanliness requirements.

[0082] In one embodiment, the guide tube 422 is a variable-diameter cylindrical structure, integrally formed by precision casting or CNC machining of stainless steel or aluminum alloy, and is coaxially arranged with the swivel blade 421. The diameter of its cylindrical shaft end gradually changes along the gas flow direction. The diameter of the shaft end of the guide tube 422 at the lower end of the swivel blade 421 is larger than that at the upper end of the swivel blade 421, so that the side wall of the guide tube 422 forms a smooth conical transition structure. The wall thickness of the cylinder remains uniform along the axial direction, ensuring the pressure bearing performance and impact resistance of the structure. This variable-diameter structure is adapted to the airflow reversal space size at the lower end of the swivel blade 421. After the clean gas completes the swirling separation by the swivel blade 421, it can smoothly enter the axial gas channel of the guide tube 422 along the large-diameter shaft end at the lower end of the guide tube 422 during the reversal process, reducing the impact and turbulence caused by the sudden change in the flow channel, effectively reducing the resistance loss during the gas flow process, and improving the flow stability of the airflow in the channel. Meanwhile, the large-diameter shaft end at the lower end of the guide tube 422 increases the contact area with the surrounding cavity, improves the structural stability of the guide tube 422 under the impact of high-pressure airflow, reduces the radial offset and vibration of the tube, ensures the overall coaxiality of the vortex assembly 420, and maintains the consistency of the vortex separation and airflow guidance effects.

[0083] In one embodiment, the lower end of the guide tube 422 is provided with several support rods. The support rods are made of the same stainless steel or aluminum alloy material as the guide tube 422 and the lower cavity, and can adopt a solid rod shape, hollow tube shape, or thin plate shape structure to take into account the requirements of structural strength and lightweight. The several support rods are evenly spaced along the circumference of the lower end of the guide tube 422 to form a stable support array. One end of the support rod is fixedly connected to the outer wall of the lower end of the guide tube 422. The connection method can be welding, integral casting, or bolt fastening. The other end is fixedly connected to the bottom end of the inner wall of the lower cavity, so that the guide tube 422 is rigidly connected to the lower cavity through the support rods. The support rods provide axial and radial positioning support for the bottom of the guide tube 422. Combined with the sealing fit between the upper end of the guide tube 422 and the inner ring of the rotor 421, this achieves bidirectional positioning of the guide tube 422, effectively preventing axial movement or radial displacement of the guide tube 422 under the continuous impact of high-pressure airflow. This ensures the coaxiality of the guide tube 422 and the rotor 421, maintains the dimensional accuracy of the internal flow channel of the rotor assembly 420, and guarantees the gas-liquid separation effect. Simultaneously, the spaced arrangement of the support rods does not obstruct the gas flow path, nor does it affect the downward settling of liquid impurities and solid particles separated in the lower cavity along the cavity wall. Impurities can settle to the bottom of the lower cavity through the gaps between the support rods, facilitating subsequent sewage discharge operations.

[0084] In one embodiment, a transition tube is provided between the internal cavity of the primary filter element 430 and the top outlet of the guide tube 422. The transition tube is arranged in the upper cavity and is a tubular structure with both ends open. Both ends of the transition tube are sealed connections. One end is sealed to the top outlet of the guide tube 422, and the other end is sealed to the inlet of the internal cavity of the primary filter element 430. Sealing structures such as gaskets or sealing rings are provided at the connection points to ensure airtightness during gas transportation and prevent gas leakage from the connection gap. The transition tube can be connected to the inner wall of the upper cavity by welding, bracket fixing, or snap-fitting to achieve its fixed positioning and prevent displacement during gas flow. A separator outlet 440 is opened on the outer wall of the upper cavity. The opening position of the separator outlet 440 corresponds to the axial position of the transition tube, that is, the separator outlet 440 is arranged directly opposite the transition tube. The transition tube provides a flexible, sealed connection between the guide tube 422 and the primary filter element 430, effectively compensating for coaxiality errors and positional deviations during installation. This ensures that all gas discharged through the guide tube 422 enters the internal cavity of the primary filter element 430 in a directed manner, preventing turbulence in the upper cavity and improving the filtration efficiency of the primary filter element 430. Simultaneously, the separator outlet 440 is positioned opposite the transition tube, allowing the clean gas filtered by the primary filter element 430 to exit the upper cavity along the shortest path, reducing gas residence time and pressure loss, and improving the overall gas delivery efficiency of the gas-water separator 400. Furthermore, the transition tube directly guides the outlet airflow of the guide tube 422 to the central area of ​​the primary filter element 430, preventing disordered diffusion of airflow in the upper cavity and improving filter element utilization.

[0085] In one embodiment, adsorption tower 100, see [reference] Figure 5-12 The system consists of an outer tube 110 and an inner tube 120 arranged coaxially within the outer tube 110. This nested layout creates an annular flow space between the outer tube 110 and the inner tube 120. The outer tube 110 has a first air outlet 111 for discharging clean gas. The inner tube 120, serving as the core purification channel, is divided into three interconnected functional areas from bottom to top: an air inlet section 121 at the bottom, an adsorption section 122 in the middle, and a dust removal section 123 at the top. By employing a tube-within-a-tube structure with the outer tube 110 and inner tube 120 coaxially arranged, the system's integration is significantly improved, and its size is reduced.

[0086] The inlet section 121 has an inlet 124 for introducing the high-pressure gas to be treated. The internal chamber of the adsorption section 122 is filled with adsorbent to remove moisture or other impurities from the gas. To securely confine the adsorbent within a specific area, a first filter screen 125 is horizontally installed at the bottom of the adsorption section 122 where it connects to the inlet section 121, while a second filter screen 126 is horizontally installed at the top of the adsorption section 122 where it connects to the dust removal section 123. At least a portion of the sidewall of the dust removal section 123 is designed as a filter layer 127 with a microporous structure; preferably, the entire sidewall of the dust removal section 123 is a filter layer 127 with a microporous structure.

[0087] In terms of specific structural implementation, the outer tube 110 can be a high-strength aluminum alloy extruded cylinder or a pressure tank made of cast steel. The inner tube 120 can be a combined support tube formed by multiple metal pipes connected by threads or fixed by clamps. The adsorbent can be activated alumina balls, molecular sieve particles, or silica gel desiccant, etc. The first filter screen 125 and the second filter screen 126 can be stainless steel woven wire mesh, sintered metal mesh, or perforated metal plates, etc. The filter layer 127 on the side wall of the dust removal section 123 can be high-pressure resistant fiber filter paper, folded metal felt, or porous ceramic filter membrane, etc., wrapped around the tube frame.

[0088] During purification operation, the high-pressure gas to be treated first enters the inlet section 121 of the inner tube 120 through the tower inlet 124. Driven by the pressure difference, the gas overcomes gravity and flows vertically upward, passing through the first filter 125 and entering the adsorption section 122. In the adsorption section 122, the gas comes into full contact with the adsorbent particles and undergoes deep drying. Subsequently, the preliminarily purified gas continues upward through the second filter 126 and enters the dust removal section 123. At this point, the gas is constrained by the top closed structure and changes its flow direction, turning into a radial flow from the inside to the outside through the filter layer 127 on the side wall.

[0089] It should be noted that in traditional adsorption towers 100, adsorbent particles are easily pulverized into fine dust particles under the impact and friction of long-term high-pressure airflow. These adsorbent dust particles can enter downstream pipelines with the airflow, causing secondary pollution and damaging downstream precision components. In this embodiment, the gas must pass through the filter layer 127 after leaving the adsorption section 122 before entering the annular gap. This structural design traps the adsorbent dust inside the inner tube 120, avoiding secondary pollution. By placing the filter layer 127 on the side wall of the dust removal section 123, the gas must pass through the filter layer 127 radially, which has two significant advantages compared to traditional axial end-face filtration. First, the filter layer 127 is continuously arranged circumferentially along the inner tube 120, and its effective filtration area is the area of ​​a cylindrical surface, which is much larger than the cross-sectional area of ​​the axial end face filtration under the same radial dimension. This significantly reduces the filtration rate and reduces air resistance under the same gas flow rate. Second, the radial flow path makes the gas form a uniform distribution pressure on the surface of the filter layer 127, avoiding local perforation failure caused by concentrated airflow impacting the central area of ​​the filter layer during axial filtration.

[0090] The filtered clean gas enters the annular gap between the inner tube 120 and the outer tube 110. This annular gap serves as a confluence and pressure stabilization point, where the gases converge and are ultimately discharged continuously from the first outlet 111 of the outer tube 110. Because the flow cross-sectional area of ​​the annular gap is much larger than the total opening area of ​​the filter layer 127 on the side wall of the dust removal section 123, the gas undergoes volume expansion here, the flow velocity decreases significantly, and the dynamic pressure is converted into static pressure, forming a low-pressure, stable air cushion zone. When multiple streams of gas enter the annular gap from different circumferential positions through the filter layer 127, they are fully mixed and pressure equalized within this air cushion zone before being discharged through the first outlet 111. This process effectively eliminates pressure fluctuations caused by local resistance differences or airflow pulsations in the filter layer 127, making the output gas pressure more stable.

[0091] The longitudinal arrangement of the inlet section 121, adsorption section 122, and dust removal section 123 in the inner tube 120 conforms to the characteristics of airflow dynamics. Specifically, the gas flows vertically from bottom to top, in the opposite direction to gravity, which is conducive to the natural sedimentation of large particles and maintains the structural stability of the adsorbent layer under gravity. The height of the adsorption section 122 can be independently designed according to the gas volume and purification requirements. Under a given gas flow rate, the contact time between the gas and the adsorbent can be controlled by adjusting the bed height, ensuring that the gas obtains sufficient residence time in the adsorbent layer to complete deep drying.

[0092] The conventional air intake method of adsorption tower 100 often leads to tunneling or localized flow deviation in the airflow within the adsorbent layer, resulting in uneven adsorbent utilization. This not only shortens the adsorbent replacement cycle but may also cause fluctuations in the dew point of the output gas. Dew point is the temperature at which water vapor in a cooled gas begins to condense into liquid or solid condensate, reflecting the moisture content of the gas. This application also provides an adsorption tower 100 including an elastic compensation mechanism 128, which can automatically eliminate gaps in the packing in real time, thereby greatly solving the tunneling effect caused by adsorbent contraction and the resulting airflow short-circuiting phenomenon.

[0093] The elastic compensation mechanism 128 is mainly composed of a clamping component 128b and an elastic pre-tightening component 128a. The clamping component 128b serves as a force-bearing or positioning reference and is securely placed within the dust removal section 123. Meanwhile, the second filter screen 126, originally located at the upper end of the adsorption section 122 to constrain the adsorbent, is designed as a movable structure, allowing it to slide freely up and down along the central axis of the inner tube 120, thereby adjusting its position in real time according to the filling height of the adsorbent.

[0094] In terms of specific structural implementation, the clamping component 128b can be a retaining spring or a ring-shaped steel plate with a certain thickness. The clamping component 128b can be fixed to the inner wall of the dust removal section 123 by means of plugging or other methods. The material of the clamping component 128b is usually stainless steel, aluminum alloy, or carbon steel with rust-proof surface treatment, which have good mechanical strength and chemical stability. The second filter screen 126 can be specifically composed of a high-hardness stainless steel support frame and multiple layers of fine wire mesh. Its outer diameter maintains a slight gap fit with the inner wall of the adsorption section 122 of the inner tube 120 to ensure smooth sliding.

[0095] The elastic preload 128a is longitudinally clamped between the clamping member 128b and the second filter screen 126. In the assembled state, the elastic preload 128a is in a pre-compressed deformation process, with its two ends tightly abutting against the bottom surface of the clamping member 128b and the top surface of the second filter screen 126, respectively. The elastic preload 128a can be specifically embodied as a cylindrical helical spring, a multi-layered stacked disc spring, or a high-elasticity, high-temperature resistant synthetic rubber column. These components can be made of high-performance spring steel, such as manganese steel or silicon-manganese alloy steel, to ensure that stable elastic force output is maintained without permanent deformation under long-term high-temperature and high-pressure environments.

[0096] This embodiment introduces a continuous axial compressive force above the adsorption section 122, making the second filter screen 126 a dynamic pressure cap that can move in real time according to the change in the internal packing volume of the adsorption section 122. When the adsorbent wears and breaks due to long-term airflow scouring or when the accumulated volume decreases due to gravitational vibration, the elastic pre-tightening member 128a releases the stored elastic potential energy and pushes the second filter screen 126 to automatically move downward. This dynamic compensation effect ensures that the adsorbent particle layer is always in a tight packing state, reduces the airflow tunneling effect induced by loose adsorbent particles, effectively prevents the degradation of purification performance caused by airflow short circuit, and ensures the long-term stability of the dew point of the output gas of the adsorption tower 100.

[0097] In one embodiment, the clamping member 128b is further designed as a threaded adjustment assembly, with continuously distributed external threads machined on its outer peripheral surface. Correspondingly, the inner peripheral wall of the dust removal section 123 of the inner tube body 120 is provided with internal threads that precisely match the external threads. This threaded pair fit creates an axially movable positioning structure inside the dust removal section 123, allowing the clamping member 128b to be installed and fixed at a predetermined depth in the dust removal section 123 by screwing it in.

[0098] The clamping component 128b can be made of a high-strength and wear-resistant metal material, such as 304 stainless steel, brass, or surface-hardened aluminum alloy. To facilitate torque transmission during assembly, the top surface of the clamping component 128b can be provided with a slotted groove, a cross-shaped groove, or circumferentially distributed lever holes for use with external tools to drive its rotation. The internal thread of the dust removal section 123 can be directly tapped into the metal wall of the inner tube 120, or a threaded metal bushing can be pre-embedded inside the tube body through interference fit, insertion, or welding.

[0099] By applying external torque to drive the clamping member 128b to rotate, the lead effect of the thread can convert the circumferential rotational motion into linear displacement along the axial direction of the inner tube 120. This change in axial position can directly act on the elastic pre-tightening member 128a, causing a change in the degree of compression it is subjected to within a limited space. Since the elastic pre-tightening member 128a is always positioned between the clamping member 128b and the second filter screen 126, the downward axial displacement of the clamping member 128b increases the deformation of the elastic pre-tightening member 128a, thereby increasing the initial clamping force on the bottom adsorbent layer. Conversely, rotating the clamping member 128b upwards can release part of the pre-tightening force.

[0100] This embodiment provides a quantifiable and fine-tunable initial pre-tightening force control method for the adsorption tower 100 through threaded rotation adjustment. This allows the adsorption tower 100 to flexibly adapt to the filling requirements of adsorbents with different materials and particle strengths. Operators can compensate for filling errors by adjusting the axial position of the clamping component 128b according to the actual filling height, ensuring that the elastic compensation mechanism 128 is always within the optimal working pressure range. This precise adjustment capability effectively avoids particle loosening and wear due to insufficient pressure, while also preventing adsorbent breakage due to excessive pressure, greatly improving the flexibility of equipment assembly and operational reliability.

[0101] When the adsorbent undergoes gradual volume shrinkage due to long-term use, exceeding the automatic compensation range of the elastic preload 128a, the compression stroke can be supplemented by manually tightening the clamping component 128b, restoring the compensation mechanism to its optimal clamping state. This dual adjustment mechanism achieves both real-time automatic compensation during operation and provides a means of manual intervention during maintenance, ensuring that the adsorbent layer remains structurally dense throughout its entire service life.

[0102] In one embodiment, the clamping member 128b is a hollow annular component. This hollow annular design provides ample space for airflow while ensuring mechanical strength. The inner ring edge of the annular component protrudes radially inward to form a stop block 128c, and multiple stop blocks 128c are spaced apart along the circumference of the inner ring of the annular component. The specific shape of the stop block 128c can be a rectangular boss, a triangular reinforcing rib, or an arc-shaped positioning tooth. During manufacturing, the stop blocks 128c and the main body of the annular component are typically integrally cast, injection molded, or formed using precision CNC machining to ensure the positional accuracy between the stop blocks 128c.

[0103] The stop block 128c serves a dual function in the structure. First, it limits the radial displacement of the elastic preload 128a. When the elastic preload 128a is installed below the clamping member 128b, its top end is constrained within the range defined by the multiple stop blocks 128c, thereby preventing the elastic preload 128a from lateral displacement, twisting, or instability due to high-pressure airflow disturbance when subjected to axial compressive force. Second, the stop block 128c also serves as a manual rotation point. Since the clamping member 128b is threadedly connected to the inner wall of the dust removal section 123, when the axial position of the clamping member 128b needs to be adjusted, the operator can insert a tool into the gap between adjacent stop blocks 128c, or directly apply circumferential torque by pressing the radial protrusion of the stop block 128c with their fingers, thereby easily tightening or loosening the clamping member 128b.

[0104] In one embodiment, the intake section 121 includes a conical portion 121b. The conical portion 121b is configured as a conical cylindrical structure with an inner diameter that gradually increases axially from bottom to top. The high-pressure gas to be treated enters the interior of the conical portion 121b from its lower end port. Multiple pillars are uniformly arranged circumferentially on the inner wall of the conical portion 121b. Each pillar extends upward from the inner wall surface of the conical portion 121b, with its top end located in the same horizontal plane. A first filter screen 125 is horizontally disposed at the bottom end of the adsorption section 122, and the lower surface of the first filter screen 125 contacts and is supported by the top ends of the multiple pillars.

[0105] The conical section 121b can be made by stamping or casting metal sheets, and the material can be stainless steel or aluminum alloy to ensure structural strength. The column can be integrally cast with the conical section 121b, or it can be a separate structure that is fixed to the inner wall of the conical section 121b by welding or threaded connection. The first filter screen 125 can be a filter material with a certain degree of rigidity, such as stainless steel woven wire mesh, sintered metal mesh, or perforated metal plate.

[0106] When high-pressure gas enters from the lower end of the conical section 121b, the gradually increasing inner diameter of the conical section 121b causes the cross-sectional area for gas flow to gradually expand along the flow direction. According to the fluid continuity equation, the gas velocity decreases accordingly, and the dynamic pressure is partially converted into static pressure. This process effectively slows down the gas flow velocity, creating conditions for a uniform gas distribution before entering the adsorption section 122.

[0107] The columns form a multi-point support structure inside the conical section 121b. The tops of the multiple columns together form a flat support plane, allowing the first filter screen 125 to be stably fixed to the bottom of the adsorption section 122. The gaps between the columns form an open gas distribution cavity, where the gas is further diffused and homogenized after being decelerated within the conical section 121b, and then uniformly passes through the first filter screen 125 into the adsorption section 122.

[0108] This structure achieves airflow deceleration and stabilization through the diffusion effect of the conical section 121b, preventing high-speed airflow from directly impacting the central area of ​​the first filter screen 125 and causing local perforation or deformation of the screen. The column support structure ensures that the first filter screen 125 remains stable under the action of bidirectional airflow, preventing the screen from denting downwards or bulging upwards due to pressure. The gas distribution chamber formed between the columns allows the gas to be evenly distributed laterally before reaching the first filter screen 125, eliminating the problem of local saturation of the adsorbent caused by concentrated airflow jets, thereby improving the overall utilization rate of the adsorbent.

[0109] In one embodiment, the air inlet section 121 further includes a cylindrical section 121a communicating with the conical section 121b. The cylindrical section 121a is configured as a straight pipe with a constant inner diameter along the axial direction. The cylindrical section 121a is located below the conical section 121b, and the lower end of the conical section 121b communicates with the upper end of the cylindrical section 121a. The tower body air inlet 124 is formed in the pipe wall of the cylindrical section 121a for introducing the high-pressure gas to be treated.

[0110] The cylindrical section 121a can be made of metal tubing, and the material can be stainless steel or aluminum alloy. The cylindrical section 121a and the conical section 121b can be fixedly connected by welding, threaded connection, or integral molding. The tower body air inlet 124 can be set as a circular through hole, which is opened radially on the tube wall of the cylindrical section 121a. The tower body air inlet 124 can be pre-threaded for connection with the external air intake pipeline.

[0111] After the high-pressure gas enters the cylindrical section 121a radially through the inlet 124 of the tower body, it first undergoes a directional change inside the cylindrical section 121a. The gas flow changes from radial to axial and moves upward along the axial direction of the cylindrical section 121a. The constant-diameter straight pipe structure of the cylindrical section 121a provides a stable flow buffer zone for the gas, causing the local turbulence generated upon entry to gradually attenuate within this zone, and the flow velocity distribution tends to be uniform. Subsequently, the gas enters the conical section 121b from the upper end of the cylindrical section 121a.

[0112] The cylindrical section 121a separates the tower inlet 124 from the conical section 121b by a certain distance, ensuring a relatively stable axial flow state for the gas before it enters the conical section 121b. This design avoids the wall-attached jet phenomenon that might occur when the tower inlet 124 is directly opened on the wall of the conical section 121b, preventing gas from directly rushing towards the edge of the first filter screen 125 along the inner wall of the conical section 121b, causing localized airflow concentration. Through the flow stabilization and buffering effect of the cylindrical section 121a, the gas enters the conical section 121b at a uniform flow rate, creating favorable initial conditions for diffusion and uniform flow in the conical section 121b. Simultaneously, the stepped or continuous combination of the cylindrical section 121a and the conical section 121b guides the gas to achieve more uniform volume diffusion during its ascent, laying the foundation for a stable laminar flow field to form in the adsorption section 122. This structural layout improves the adsorption tower 100's ability to withstand instantaneous high-pressure impacts and enhances the stability of the purification process.

[0113] In one embodiment, a vent hole 112 is provided on the wall of the outer tube 110 for communicating with external clean gas. A second outlet 129 is provided at the lower end of the cylindrical portion 121a for discharging gas during regeneration. The vent hole 112 can be a circular through hole, radially formed on the wall of the outer tube 110. Internal threads can be pre-machined at the vent hole 112 for connection to an external pipeline. The second outlet 129 is located at the bottom end or near the bottom end of the cylindrical portion 121a, with its opening facing downwards or to the side, for connection to an external discharge pipeline. A one-way valve or a solenoid switching valve can be added at the connection between the second outlet 129 and the external pipeline to precisely control the flow of air. Both the vent hole 112 and the second outlet 129 can be sealed by welding or threading metal pipe fittings to the tube body.

[0114] During regeneration, the second outlet 129 is opened, reducing the air pressure inside the inner tube 120. The pressure inside the outer tube 110 is greater than that inside the inner tube 120, allowing clean gas to enter the outer tube 110 through the vent 112. Since an annular gap is formed between the outer tube 110 and the inner tube 120, the clean gas first fills this gap. Driven by the pressure difference, the clean gas radially inwards through the filter layer 127 on the side wall of the dust removal section 123 and enters the interior of the dust removal section 123. The gas then flows downwards, passing sequentially through the second filter 126, the adsorbent in the adsorption section 122, and the first filter 125, entering the cylindrical portion 121a of the inlet section 121, and finally exiting from the second outlet 129 at the lower end of the cylindrical portion 121a. The opening and closing of the second outlet 129 can be controlled by the solenoid valve 130.

[0115] In this regeneration mode, the gas flow direction is opposite to that in the purification mode, forming a counter-current regeneration path and producing a significant backwashing effect. During the counter-current regeneration process, dry, clean gas passes through the adsorbent from top to bottom, carrying away the moisture and impurities adsorbed inside the adsorbent. Simultaneously, as the gas flows in the reverse direction through the filter layer 127, the first filter screen 125, and the second filter screen 126, it blows away the adsorbent dust adhering to the surfaces of these elements, achieving self-cleaning of the filter layer 127, the first filter screen 125, and the second filter screen 126. This structural design not only extends the service life of the core adsorption section 122 but also greatly improves the automated regeneration efficiency of the adsorption tower 100, ensuring the reliability of the adsorption tower 100 during continuous operation.

[0116] In one embodiment, the adsorption tower 100 further includes a regeneration gas chamber 113. The regeneration gas chamber 113 is connected to the outer pipe body 110 through a vent 112. Specifically, the regeneration gas chamber 113 can be a metal tank welded to the outer wall of the outer pipe body 110, or an independent cylindrical container connected to the vent 112 via a high-pressure hose and connector. Its material is typically chosen for its good pressure resistance and chemical stability, such as aluminum alloy, stainless steel, or carbon steel with rust-proof inner walls. The volume of the regeneration gas chamber 113 is proportioned according to the amount of adsorbent loaded in the adsorption tower 100 to ensure that the stored clean gas is sufficient to complete one complete backwash cycle.

[0117] Under purification conditions, the gas to be treated is dried in the adsorption section 122 and then enters the dust removal section 123. It then radially passes through the filter layer 127 and enters the annular gap between the inner tube 120 and the outer tube 110. After the gas collects in the annular gap, a portion of the gas is discharged from the first outlet 111 of the outer tube 110 for use by downstream equipment. The other portion of the gas enters the regeneration gas chamber 113 through the vent 112 and is stored there. The gas entering the regeneration gas chamber 113 is clean gas that has undergone deep drying in the adsorption section 122 and precise filtration in the dust removal section 123; it has a low dew point and is free of impurities.

[0118] Under regeneration conditions, the clean gas stored in the regeneration gas chamber 113 is driven by the pressure difference and flows in reverse from the regeneration gas chamber 113 into the outer pipe 110 through the vent 112. The clean gas then flows along the counter-current path through the filter layer 127, the second filter screen 126, the adsorbent, and the first filter screen 125, and is discharged from the second outlet 129 at the lower end of the columnar section 121a, completing the backwash regeneration of the internal structure of the adsorption tower 100.

[0119] This embodiment achieves pre-storage of a portion of clean gas under purification conditions by setting a regeneration gas chamber 113 outside the adsorption tower 100, and utilizes this pre-stored gas for backflushing regeneration under regeneration conditions. The introduction of the regeneration gas chamber 113 enables the adsorption tower 100 to have energy self-balancing capability, eliminating the need for an external regeneration power source. The gas used in the regeneration process originates from the clean gas purified by the adsorption tower 100 itself, ensuring the purity of the regeneration gas and avoiding secondary pollution that may be introduced by an external gas source. The setting of the regeneration gas chamber 113 also decouples the regeneration operation from the purification conditions in time. Under purification conditions, gas can be slowly filled into the regeneration gas chamber 113, and under regeneration conditions, the regeneration gas chamber 113 can release gas instantaneously, meeting the instantaneous gas volume requirements of backflushing regeneration.

[0120] In one embodiment, the gas nano-purifier further includes a sludge collection chamber 230, which is fixed to the mounting base 600 and has a sludge inlet 220. The gas-liquid separator 400 has a first sludge outlet 450, and the adsorption tower 100 has a second sludge outlet. The sludge inlet 220 is connected to both the first and second sludge outlets. The first sludge outlet 450 is located at the bottom end of the lower cavity of the gas-liquid separator 400 and is connected to the lower cavity of the gas-liquid separator 400. Impurities filtered by the gas-liquid separator 400 are discharged into the sludge collection chamber 230 through the first sludge outlet 450. The second sludge outlet of the adsorption tower 100 is also the second gas outlet 129 of the adsorption tower 100 in the above embodiment.

[0121] Both the gas-liquid separator 400 and the adsorption tower 100 can be equipped with control sensing components. By real-time monitoring of information such as pressure, liquid level, and gas flow rate in the gas-liquid separator 400 and the adsorption tower 100, the opening and closing of the first drain port 450 and the second gas outlet 129 can be controlled. Specifically, for example, liquid level sensors can be installed at the bottom of the gas-liquid separator 400 and the adsorption tower 100. When the liquid level reaches a preset height, the liquid level sensor will send a signal to the controller, automatically opening the first drain port 450 and the second gas outlet 129 to achieve automatic drainage. The controller can be a solenoid valve or a butterfly valve.

[0122] The sludge collection bin 230 is configured as an independent closed or semi-closed container, made of metal materials such as stainless steel or carbon steel, providing a centralized buffer space for the waste discharged from the gas-liquid separator 400 and the adsorption tower 100. The shape of the sludge collection bin 230 can be configured as a rectangular box or a cylindrical cylinder, with an internal cavity for containing the regeneration waste gas. The sludge inlet 220 is opened on the wall of the sludge collection bin 230.

[0123] See Figure 13-14 The sludge collection bin 230 is equipped with an inclined baffle 233. The inclined baffle 233 is made of metal sheet and is generally flat or curved, and is fixedly installed on the inner wall of the sludge collection bin 230. The inclined baffle 233 can be a solid metal flat plate, a guide plate with a fine texture, or a composite plate with a sound-absorbing coating. The inclined baffle 233 has a first end and a second end, with the first end positioned higher than the second end in the direction of gravity; that is, the inclined baffle 233 is arranged along an inclined direction, with the first end at a higher position and the second end at a lower position. The inclined baffle 233 can be fixed by welding, bolting, or plugging, securing the edge of the inclined baffle 233 to the inner wall of the sludge collection bin 230.

[0124] The first end of the inclined baffle 233 is located below the waste inlet 220, allowing the exhaust gas discharged from the waste inlet 220 to be directly sprayed onto the upper surface of the inclined baffle 233. Through the cooperation between the waste collection bin 230 and the inclined baffle 233, the problems of random gas-liquid spraying and physical impact during the regeneration process are effectively solved. The inclined baffle 233, utilizing its tilt angle and physical barrier effect, transforms the originally highly destructive directional jet into a controlled fluid sliding along the baffle surface, greatly reducing the direct impact of the airflow on the inner wall of the waste collection bin 230 and providing excellent structural protection. Simultaneously, utilizing the inertial collision effect, the water vapor and oil mist carried in the airflow rapidly condense and converge into droplets after impacting the inclined baffle 233. Guided by gravity, these droplets flow along the inclined baffle 233 from the first end to the second end, eventually settling smoothly into the bottom of the waste collection bin 230. This design significantly improves the gas-liquid separation efficiency, ensures that waste can be stably collected in a specific area, and greatly improves the cleanliness of the surrounding environment.

[0125] In one embodiment, the gas nano-purifier includes two vent valves 300 and two adsorption towers 100. The two adsorption towers 100 are a first adsorption tower 100 and a second adsorption tower 100, respectively, and the two vent valves 300 are a first vent valve and a second vent valve, respectively.

[0126] Two adsorption towers 100 are symmetrically mounted on a mounting plate 510. Specifically, the mounting plate 510 has a rectangular plate structure with left and right sides in the horizontal direction. The first adsorption tower 100 and the second adsorption tower 100 are fixed to the left and right sides of the mounting plate 510, respectively, and are mirror-symmetrical with respect to the vertical center line of the mounting plate 510. The air inlet 124 of the adsorption tower 100 is used to receive the gas processed by the gas-water separator 400, and the first air outlet 111 is used to output the gas purified by the adsorption tower 100 to the gas storage chamber 500.

[0127] Both vent valves 300 are installed between the two adsorption towers 100, that is, the first vent valve and the second vent valve are located in the area between the first adsorption tower 100 and the second adsorption tower 100. The first vent valve is located at the lower end of the second vent valve. The shells of the first vent valve and the second vent valve are integrally formed, and the two ends of the shells are respectively fixed to the outer walls of the outer tubes 110 of the first adsorption tower 100 and the second adsorption tower 100.

[0128] One end of the first drain valve is connected to the gas-liquid separator 400, and the other end is used to connect to the air inlet of the first adsorption tower 100 or the second adsorption tower 100, i.e., the tower body air inlet 124. Specifically, the first drain valve has a common interface 311 and two switching interfaces 312. The common interface 311 is connected to the separator outlet 440 of the gas-liquid separator 400, and the two switching interfaces 312 are respectively connected to the tower body air inlet 124 of the first adsorption tower 100 and the tower body air inlet 124 of the second adsorption tower 100. The internal valve core 330 of the first drain valve moves automatically under the action of the pressure difference between the two ends, so that the common interface 311 is alternately connected to one of the switching interfaces 312, thereby realizing the alternating delivery of the gas discharged from the gas-liquid separator 400 to the first adsorption tower 100 or the second adsorption tower 100.

[0129] One end of the second vent valve is connected to the gas storage chamber 500, and the other end is used to connect to the gas outlet of the first adsorption tower 100 or the second adsorption tower 100, i.e., the first gas outlet 111. Specifically, the second vent valve also has a common interface 311 and two switching interfaces 312. The common interface 311 is connected to the gas inlet of the gas storage chamber 500, and the two switching interfaces 312 are respectively connected to the first gas outlet 111 of the first adsorption tower 100 and the first gas outlet 111 of the second adsorption tower 100. The internal valve core 330 of the second vent valve also automatically switches according to the pressure difference between the two ends, so that the common interface 311 is alternately connected to one of the switching interfaces 312, thereby transporting the dry gas output from the adsorption tower 100 in the adsorption state to the gas storage chamber 500 for storage.

[0130] By installing two relief valves 300 between two adsorption towers 100 and symmetrically arranging the two towers 100, a compact gas path layout is formed. The first relief valve is responsible for inlet gas distribution, and the second relief valve is responsible for outlet gas collection. Working together, they achieve automatic switching between alternating adsorption and regeneration of the two towers without the need for external electrical control. The symmetrical installation of the two adsorption towers 100 places the center of gravity of the entire unit at the center of the mounting plate 510, resulting in balanced stress and improved equipment stability. The relief valves 300, located between the two towers, shorten the length of the connecting pipelines, reducing pressure drop and leakage risks, while also facilitating maintenance and repair. This layout makes full use of the planar space of the mounting plate 510, making the overall structure more compact and suitable for installation and use in limited spaces.

[0131] In one embodiment, a drain valve 300, see [reference] Figures 15-21Its core structure lies in the automated switching of flow channels achieved through an integrated valve body 310 and internally symmetrically arranged power components. The valve body 310, serving as the external carrier and pressure vessel of the entire device, has its internal space precisely divided into a flow passage area and a functional installation area. In terms of spatial layout, the valve body 310 has a common interface 311 in the middle for connecting to the system's main pipeline, while two switching interfaces 312 are symmetrically arranged at its two ends. This three-port flow channel design, combined with the internally continuous fluid channels, constitutes the physical basis for supporting multi-directional fluid flow.

[0132] Inside the fluid passage of the valve body 310, a pair of valve seats 320 are fixedly installed in a centrally symmetrical manner. Each valve seat 320 is not only a physical support component, but also defines an independent valve chamber. The valve chamber, as the core transit space for fluid exchange, has one end that remains normally open to the central common interface 311, while the other end points to the corresponding switching interface 312. This structural design ensures that the fluid, after entering the valve chamber, has the possibility of flowing in different directions. The valve seats 320 can be made of corrosion-resistant and high-strength materials such as stainless steel, high-strength aluminum alloy, or engineering plastics to withstand the erosion and pressure loads of different fluid media.

[0133] The valve core 330, as a moving component that performs flow channel switching, is slidably positioned across and between the two valve chambers. Driven by the pressure difference between its two ends, the valve core 330 undergoes axial displacement. When the pressure at one end is higher than the other, the resultant force generated by the pressure difference pushes the valve core 330 towards the low-pressure side. At the end of its travel, the end structure of the valve core 330 forms a sealing fit with the switching interface 312 on the low-pressure side, thereby closing the flow channel on that side; simultaneously, the high-pressure side switching interface 312, which was originally closed, is opened. This dynamic logic of alternating closure and opening allows the fluid to automatically switch flow directions based on the system's own pressure fluctuations without external control interference.

[0134] This embodiment utilizes the pressure energy of the medium itself to drive the valve core 330, eliminating the reliance on electromagnetic drive components, sensors, and complex electronic control logic for the valve 300. This purely mechanical differential pressure response mechanism significantly improves the reliability of the switching action, especially under harsh conditions such as high-frequency switching or flammable and explosive environments, effectively avoiding safety hazards caused by electrical failures. Furthermore, the symmetrical layout of the valve seat 320 and valve cavity ensures force balance during flow channel switching, reducing friction and wear of moving parts, thereby extending the overall maintenance cycle and service life of the device.

[0135] In one embodiment, the valve seat 320 adopts a modular stacked structure, forming a core space for guiding fluid and accommodating moving parts through the precise axial engagement of multiple independent functional components. Specifically, the valve seat 320 is composed of a locking element 321, a limiting sleeve 322, and a baffle seat 323 arranged sequentially and tightly combined in the axial direction. The locking element 321 serves as the axial fastening power source for the entire assembly, and its outer peripheral wall is provided with locking threads. By engaging with the internal threads on the inner wall of the valve body 310, the rotational torque is converted into axial clamping force. The locking element 321 can be made of chrome-plated carbon steel or high-strength alloy steel to ensure the reliability and fatigue resistance of the threaded connection.

[0136] The limiting sleeve 322, a key component defining the axial length of the valve cavity, is located between the locking member 321 and the baffle seat 323. The limiting sleeve 322 is typically a hollow cylindrical tubular structure, with its axial end faces machined for flatness to ensure tight contact with adjacent components. The baffle seat 323 is located at the innermost side of the valve seat 320 and directly bears the fluid distribution function. In the assembled state, the screwing action of the locking member 321 transfers the axial load sequentially to the limiting sleeve 322 and the baffle seat 323, ultimately firmly pressing the baffle seat 323 against the pre-set stepped or stepped surface on the inner wall of the valve body 310. This method of fixing through mechanical pressing avoids complex welding or adhesive processes, greatly improving the mechanical stability of the internal structure.

[0137] A closed and controlled valve chamber is formed by the inner diameter surface of the locking element 321, the inner diameter surface of the limiting sleeve 322, and the inner surface of the baffle seat 323. This valve chamber not only serves as a physical channel for fluid exchange but also provides precise stroke space for the reciprocating movement of the valve core 330. The limiting sleeve 322 and the baffle seat 323 can be made of stainless steel, brass, or erosion-resistant composite ceramic materials, depending on the characteristics of the medium. This three-in-one combined valve seat 320 design ensures a high degree of consistency in the valve chamber geometry, and the opening and closing stroke of the valve core 330 can be precisely controlled by adjusting the axial length of the limiting sleeve 322. In addition, this split configuration allows for independent replacement of each component, significantly reducing the maintenance difficulty and parts replacement cost after long-term wear.

[0138] In one embodiment, the valve core 330, serving as the core actuator for flow path switching, primarily comprises a connecting rod 331 and baffle assemblies 332 symmetrically fixed to both ends of the connecting rod 331. The connecting rod 331, acting as a rigid frame for power transmission, spans between the two valve chambers. It can be made of stainless steel, alloy steel, or surface-hardened metal rods to ensure sufficient axial rigidity and fatigue resistance during frequent reciprocating linear motion. The baffle assemblies 332, as components directly in contact with the fluid and providing a sealing function, have precisely designed outer diameters that confine them within the corresponding valve chambers.

[0139] During dynamic operation, the baffle assembly 332 is configured to displace under the influence of the fluid pressure difference generated across the valve core 330. When the fluid pressure in one valve chamber exceeds that of the other, the resulting pressure difference acts on the connecting rod 331 through the baffle assembly 332, driving the entire valve core 330 to slide axially towards the low-pressure side. This displacement causes the baffle assembly 332 on the low-pressure side to move towards the corresponding switching interface 312 and eventually abut, thereby physically cutting off the flow path on that side. Simultaneously, the baffle assembly 332 on the high-pressure side moves away synchronously with the connecting rod 331, releasing the flow path of the switching interface 312 on that side. The baffle assembly 332 can be constructed as a single-layer or multi-layer stacked disc-shaped structure. Its material can be selected from synthetic rubber, fluoroplastics, or a composite structure of metal substrate and elastic sealing layer with a certain degree of elasticity, to balance mechanical strength and airtightness.

[0140] This valve core 330 configuration, combining the connecting rod 331 with the baffle assembly 332, achieves a highly responsive differential pressure drive logic. Since the baffle assembly 332 is directly located within the valve cavity and serves as a pressure sensing unit, its force-bearing area and movement trajectory exhibit extremely high consistency, enabling rapid response to minute fluctuations in system pressure. By fixing the baffle assembly 332 to both ends of the connecting rod 331, the device ensures a high degree of linkage and interlocking between the two switching ports 312 in their operation; that is, the closure of one port is necessarily accompanied by the opening of the other, effectively avoiding dead zones during flow channel switching. Furthermore, this structural design is extremely compact, minimizing the number of moving parts, which not only reduces fluid resistance loss but also significantly reduces action lag caused by mechanical friction, thereby ensuring the switching accuracy and operational stability of the valve 300 in various complex fluid environments.

[0141] In one embodiment, the flow channel structure and spatial relationship inside the valve 300 are defined to construct an efficient and non-interfering fluid transmission path. Specifically, the locking member 321 has a first through hole 321a extending through its axis in the middle, which directly serves as the terminal flow channel connecting the valve cavity and the switching interface 312. Meanwhile, the baffle seat 323 adopts a double-hole design, with a second through hole 323a in the middle and multiple third through holes 323b distributed circumferentially. In this layout, the valve cavity achieves controlled communication with the switching interface 312 through the first through hole 321a, and achieves constant communication with the common interface 311 through the third through holes 323b. This multi-hole spatial arrangement allows fluid input from the common interface 311 to enter the valve cavity through the third through holes 323b around the baffle seat 323, and then selectively exit through the first through hole 321a in the center of the locking member 321 according to the position of the valve core 330, achieving a scientific distribution of fluid dynamics.

[0142] The connecting rod 331, as an integral actuator, has its two ends passing through the second through holes 323a in the middle of the two baffle seats 323 and extending into the corresponding valve chambers, thereby rigidly linking the motion states of both sides. To achieve reliable flow path interruption, the outer diameter of the baffle assembly 332 is configured to be larger than the diameters of the first through hole 321a and the second through hole 323a, respectively. When the valve core 330 is pressed and displaced to the end of its stroke, the baffle assembly 332 can completely cover and press against the end face of the first through hole 321a, thereby cutting off the flow path to the switching interface 312. The baffle assembly 332 can adopt a composite structure of a rubber sealing layer and a metal skeleton, utilizing its radial dimension advantage to cover the first through hole 321a, while its back side can abut against the central area of ​​the baffle seat 323 to achieve axial limitation. The outer diameter of the baffle assembly 332 is configured to be larger than the diameter of the second through hole 323a, so that the baffle assembly 332 will not detach from the second through hole 323a of the baffle seat 323.

[0143] Specifically, this embodiment optimizes the fluid connectivity stability through geometric projection relationships. The axial projection of the baffle assembly 332 and the axial projection of the third through hole 323b are configured not to completely overlap. This means that when the valve core 330 moves inward and abuts against the baffle seat 323, the edge of the baffle assembly 332 will not completely block the circumferentially distributed third through holes 323b, thereby ensuring that there is always physical space for fluid circulation between the common interface 311 and the valve cavity. This non-overlapping projection design avoids the risk of common flow channel blockage caused by the movement of the valve core 330 from the structural source. The baffle seat 323 can be made of high-strength alloy or other materials, and its circumferential third through hole 323b can be processed into a waist-shaped hole, a fan-shaped hole, or a circular array hole, etc., to maximize the flow area while ensuring support strength.

[0144] By differentiating the functions of the first through-hole 321a, the second through-hole 323a, and the third through-hole 323b, and in conjunction with the size difference and projection avoidance logic of the baffle assembly 332, it is ensured that the common flow channel remains open when the evacuation valve 300 performs a switching action, while the switching flow channel can achieve instantaneous and relatively thorough shut-off. This design effectively reduces the local pressure loss of fluid in complex channels, prevents pressure fluctuations caused by the valve core 330 blocking, and improves the smoothness and response accuracy of the evacuation valve 300 in precision pneumatic or hydraulic control systems.

[0145] In one embodiment, the locking member 321, near the valve cavity, employs a stepped coaxial end face design, spatially dividing it into two distinct annular regions. See also Figures 19-20Located at the outermost radial edge of the locking element 321 is an annular abutment surface 321b, which is a flat annular surface. In the assembled state, this annular abutment surface 321b acts directly on the end of the limiting sleeve 322, firmly pressing it into the preset position through axial load. This edge abutment design ensures uniform transmission of the fastening force and effectively prevents the limiting sleeve 322 from displacing under complex pressure pulsations.

[0146] The annular sealing seat 321c is located in the central region of the annular abutment surface 321b and protrudes significantly into the valve cavity. The first through hole 321a axially penetrates the center of the annular sealing seat 321c, forming the core channel for fluid discharge. The surface of the annular sealing seat 321c is specifically configured as a sealing interface for physical contact with the moving baffle assembly 332. Due to the axial height difference and inward protrusion of the annular sealing seat 321c relative to the annular abutment surface 321b, the sealing interface is closer to the movement trajectory of the baffle assembly 332, shortening the effective sealing stroke. The locking element 321 can be made entirely of wear-resistant stainless steel or hard alloy material, and the surface of its annular sealing seat 321c can be precision ground, polished, or hardened to improve the fitting accuracy of the sealing pair.

[0147] This dual-ring coaxial configuration achieves functional separation between structural rigidity and precision sealing. The annular contact surface 321b bears the main mechanical assembly stress, while the inwardly protruding annular sealing seat 321c focuses on providing reliable sealing contact. This protruding design not only effectively guides the axial positioning of the baffle assembly 332, but also generates higher contact pressure per unit area at the moment of sealing, thereby ensuring high airtightness during flow channel switching. In addition, the protruding structure of the annular sealing seat 321c provides physical clearance space for fluid flow within the valve cavity, reducing turbulence at the moment of valve closure and significantly improving the smoothness and response speed of the reversing action.

[0148] In one embodiment, the outer circumferential surface of the annular sealing seat 321c at the center of the locking member 321 is machined into a specific bevel. As the sealing seat extends from the body of the locking member 321 into the valve cavity, its cross-sectional area gradually decreases, forming a structure similar to a chamfer or a cone. This means that the top of the annular sealing seat 321c, i.e., the surface that directly contacts the baffle assembly 332, is the part with the smallest outer diameter in the entire protruding structure. By defining the outer diameter of the annular sealing seat 321c as a gradually narrowing structure, the contact bandwidth of the sealing pair is physically reduced to improve sealing tightness, and a smooth pressure gradient transition zone is constructed in the flow channel. The flow-guiding effect of the bevel eliminates the back pressure impact and eddy current disturbance generated by the fluid at the moment of valve opening and closing, making the axial force on the valve core 330 assembly more stable, effectively avoiding jamming or response delay caused by pressure fluctuations, thereby achieving high-frequency stable commutation of the valve core 330 while ensuring sealing tightness.

[0149] In one embodiment, see Figures 19-20 An elastic sealing ring 324 is provided between the locking member 321 and the limiting sleeve 322. This elastic sealing ring 324 is positioned in the physical gap at the junction of the locking member 321 and the limiting sleeve 322. The axial clamping force generated when the locking member 321 is screwed into the valve body 310 causes the elastic sealing ring 324 to undergo radial or axial elastic deformation within the confined space, thereby blocking the path of fluid leakage along the component connection gap. The elastic sealing ring 324 can adopt a typical ring structure, and its cross-section can be designed as circular, rectangular, or star-shaped according to the shape of the sealing groove. In terms of material selection, the elastic sealing ring 324 is made of an elastomer material with excellent resistance to compression set, media corrosion, and aging, such as fluororubber, EPDM rubber, nitrile rubber, or perfluoroether rubber. An annular sealing groove can be pre-machined on the end face of the locking member 321 or the limiting sleeve 322 to radially position the elastic sealing ring 324, preventing it from shifting during assembly or being extruded and damaged under pressure fluctuations.

[0150] In one embodiment, see Figures 17-21The baffle assembly 332 includes a first baffle 333 and a second baffle 334 arranged sequentially along the axial direction. The first baffle 333 is made of rubber and is located near the locking member 321, while the second baffle 334 is made of metal and is located near the baffle seat 323. The baffle assembly 332 provided in this embodiment adopts a functionally layered composite configuration. By arranging components with different material properties axially, it achieves a synergistic improvement in sealing performance and mechanical strength. The baffle assembly 332 is divided into a first baffle 333 and a second baffle 334 arranged sequentially along the axial direction. The first baffle 333, as an elastic element that directly performs the sealing action, is located near the first through hole 321a, i.e., facing the locking member 321. The first baffle 333 is made of a rubber material with high resilience and excellent physical sealing properties, such as fluororubber, nitrile rubber or silicone rubber, to compensate for the gap between the sealing surfaces through its own slight elastic deformation when it abuts against the locking member 321, thereby ensuring the absolute airtightness of the switching interface 312 in the closed state.

[0151] The second baffle 334, serving as the rigid framework and load-transfer component of the baffle assembly 332, is positioned adjacent to the first baffle 333 and close to the baffle seat 323. The second baffle 334 is made of metal, typically stainless steel, brass, or high-strength alloy steel. Structurally, the second baffle 334 is a flat disc or a sheet-like component with reinforcing ribs. Its rigid support ensures that the first baffle 333 will not undergo excessive deformation or edge overturning when subjected to high-pressure fluid impact. This combination of metal and rubber provides the baffle assembly 332 with both soft-seal characteristics and a robust mechanical limiting foundation, effectively coping with the impact loads generated by frequent system reversals.

[0152] The rubber material of the first baffle 333 ensures immediate sealing response under low pressure differential conditions, while the metal material of the second baffle 334 solves the problem of fatigue damage or being squeezed into the channels of rubber components under long-term high-frequency impact. When the valve core 330 moves towards the baffle seat 323, the metal second baffle 334 can mechanically abut against the baffle seat 323 and play a reliable stroke limiting role, preventing frictional loss caused by direct contact between the elastic sealing material and the baffle seat 323. Through this complementary cooperation of soft and hard materials, the baffle assembly 332 significantly improves the fatigue resistance of the core moving components while ensuring the tightness of the valve 300 switching, providing physical protection for the long-term stable operation of the drying and purification system.

[0153] In one embodiment, the inner diameter of the first baffle 333 is larger than the inner diameter of the second baffle 334. By limiting the inner diameter of the first baffle 333 to be larger than the inner diameter of the second baffle 334, a stepped clearance area is formed at the root of the baffle assembly 332 to compensate for the radial deformation of the first baffle 333 under axial compression. This ensures that after the rubber is deformed under pressure, its inner edge will not interfere with the screwing of the nut 335 due to excessive compression, nor will the baffle assembly 332 as a whole be axially skewed due to the squeezed gap.

[0154] In one embodiment, the connecting rod 331 has external threads at both ends and is equipped with nuts 335. The nuts 335 press and fix the baffle assembly 332 to the end of the connecting rod 331, and the outer diameter of the nuts 335 is smaller than the diameter of the first through hole 321a. The connecting rod 331, as the transmission center running through the entire flow channel, has external threads machined at both ends located inside the valve cavity. These external threads can be standard fine threads or trapezoidal threads to enhance the self-locking performance of the connection. Each end of the connecting rod 331 is fitted with a nut 335, and the engagement of the nut 335 with the external thread generates an axial clamping force. The nut 335, as a key fastening element, can be a hexagonal nut 335, a round nut 335, or a flange nut 335 with an anti-loosening structure. Its material is typically stainless steel or hard alloy that matches the connecting rod 331 to ensure chemical stability under long-term fluid scouring conditions.

[0155] Under this assembly logic, the nut 335 securely presses and fixes the baffle assembly 332 to the shoulder or preset position of the connecting rod 331 through a screwing action. This threaded fastening method ensures a rigid connection between the baffle assembly 332 and the connecting rod 331, effectively preventing axial displacement or wobbling of the baffle assembly 332 during frequent alternation of pressure differences at both ends. Simultaneously, this embodiment precisely defines the radial dimension of the nut 335, specifically, the maximum outer diameter of the nut 335 is configured to be smaller than the diameter of the central first through hole 321a of the locking member 321. This means that when the nut 335 moves with the connecting rod 331, it can freely extend into or pass through the internal space of the first through hole 321a without interfering with or colliding with the hole wall of the first through hole 321a.

[0156] Because the outer diameter of the nut 335 is smaller than the diameter of the first through hole 321a, the nut 335 can be inserted into the first through hole 321a as part of the valve core 330, thereby maximizing the use of the axial space inside the valve body 310 and shortening the overall valve length. This space-avoiding design ensures that the movement trajectory of the valve core 330 is unobstructed when performing the switching action, thus ensuring that the baffle assembly 332 can achieve a complete and flat sealing contact with the end face of the locking member 321, significantly improving the smoothness of the valve 300's operation and the tightness of its sealing under high-speed switching conditions.

[0157] In one embodiment, the surface of the first baffle 333 is provided with an annular boss 333a along its circumference, and the surface of the nut 335 is provided with an annular groove 335a that matches the annular boss 333a. When the nut 335 presses and fixes the baffle assembly 332 to the end of the connecting rod 331, the annular boss 333a is embedded in the annular groove 335a. This embodiment further optimizes the mechanical connection strength and sealing stability of the valve core 330 end, and achieves radial limiting and anti-dislodgement functions between components through specific micro-morphological matching. The surface of the first baffle 333 is constructed with an annular boss 333a along its circumference. The annular boss 333a is a continuous or discontinuous annular ridge extending axially from the baffle plane. Correspondingly, the pressing end face of the nut 335 is machined with an annular groove 335a that perfectly matches the annular boss 333a in geometric dimensions and spatial position. The polarity matching of the boss and the groove forms a set of mechanical interlocking interfaces at the end of the connecting rod 331.

[0158] During assembly, when the nut 335 tightens and fixes the baffle assembly 332 to the end of the connecting rod 331 through threaded engagement, the annular boss 333a on the surface of the first baffle 333 is axially compressed and completely embedded in the annular groove 335a on the surface of the nut 335. The first baffle 333, as an elastic sealing element, is typically made of materials with excellent resilience, such as fluororubber, EPDM rubber, or high-density polyurethane, while the nut 335 is made of rigid materials such as stainless steel or hard alloy. This embedded fit between dissimilar materials not only enhances the frictional resistance of the contact interface but, more importantly, forms a physical barrier in the radial direction, preventing the elastic first baffle 333 from radial displacement or creeping when subjected to lateral shear force from the fluid or high-frequency vibration.

[0159] Through the precise coupling of the annular boss 333a and the annular groove 335a, the constraint force of the nut 335 on the first baffle 333 is upgraded from simple end-face friction to mechanical shear resistance, greatly improving the stress state of soft rubber materials under high-speed switching conditions. Furthermore, this structure also provides automatic centering, ensuring that the first baffle 333 remains coaxial with the connecting rod 331, thus guaranteeing the circumferential consistency of the sealing interface when sealing the first through hole 321a. This interlocking design effectively avoids the risk of uneven wear or dislodgement of the seal due to long-term impact, providing reliable mechanical protection for the long-term operation of the valve 300.
