A buffer separation device for a gas compressor

Abstract

This invention discloses a buffer separation device for a gas compressor, belonging to the technical field of separation devices. The device includes a separation tank, a centrifugal assembly, and a recovery assembly. This solution utilizes baffles to stabilize and redirect the centrifuged gas flow, achieving inertial sedimentation of medium-sized droplets. The gas flow, which may contain sputtered liquid mist, is then collected and treated. At the sharp bend in the recovery pipe, tiny droplets generated by sputtering impact the outer wall of the bend due to inertia and are firmly adsorbed and locked by adsorption strips, thus achieving final collection of secondary contaminants and ensuring extremely high dryness of the outlet gas. Simultaneously, the adsorbed liquid can be automatically heated and evaporated and discharged during shutdown, restoring the gas to its original condition. The water-absorbing ring for collecting fluid from the wall is equipped with a squeezing assembly driven by a wave-shaped abutment groove, enabling periodic squeezing and dehydration, fundamentally consolidating the long-term effectiveness in solving the secondary entrainment problem and ensuring consistently stable separation performance.

Description

Technical Field

[0001] This invention relates to the field of separation device technology, and in particular to a buffer separation device for a gas compressor. Background Technology

[0002] In gas compressors and subsequent process systems, the efficient removal of liquid components (such as water, oil mist, or condensate) from process gases is crucial for ensuring long-term stable operation of equipment, preventing liquid hammer damage, and improving the quality of gas products. Currently, gas-liquid separation using the principle of physical centrifugal force is one of the most widely used and efficient technologies. Specifically, by designing a spiral channel or tangential inlet structure, the liquid-containing gas is made to rotate at high speed within the device. The gas and liquid phases of different densities are rapidly separated in a strong centrifugal force field. Larger droplets are thrown towards the outer wall and initially collected. This method exhibits excellent separation performance for visible, large-diameter droplets, with high processing efficiency and rapid response.

[0003] However, as industrial applications demand increasingly stringent requirements for gas dryness, the limitations of this technology have become increasingly apparent. The core problem lies in the incomplete match between the "separation" and "discharge" stages. During the high-speed rotating separation process, droplets are forcibly thrown against the spiral pipe wall, but the liquid film or droplet clusters adhering to the wall cannot be completely removed instantly. Under the influence of gravity, this liquid slowly moves downstream along the complex spiral wall, coalesces, and eventually drips. This dripping often occurs in areas where the airflow is still active. When the liquid hits the bottom or other internal structures, it inevitably produces violent splashing, forming numerous secondary liquid mists. More importantly, the mainstream gas flow, which has already completed primary centrifugal separation and is flowing downstream towards the baffle elements (such as baffles), will inevitably carry these newly formed small droplets with it.

[0004] This causes a certain amount of the liquid that has already been separated to be carried away again by the airflow, resulting in a "secondary entrainment" effect. This problem seriously weakens the effect of the initial centrifugal separation, resulting in the residual liquid droplet content in the outlet gas failing to meet the requirements of high-end applications. This has become a key technical bottleneck restricting the further improvement of the performance of existing centrifugal separators. Summary of the Invention

[0005] This invention provides a buffer separation device for a gas compressor, which can solve the problem in the prior art where liquids separated by centrifugation are carried away by the airflow again, resulting in a secondary entrainment effect.

[0006] A buffer separation device for a gas compressor includes: a separation tank, a centrifugal assembly, and a recovery assembly. The separation tank has an inlet and an outlet on both sides. The centrifugal assembly is installed inside the separation tank and provides a flow path for the mixed gas discharged from the inlet, causing centrifugal force to separate the mixed gas into large liquid particles and the gas to be collected. The recovery assembly includes multiple recovery bends and multiple evaporation bends, with the evaporation bends installed on the outside of the recovery bends. The recovery bends change the flow direction of the gas to be collected, causing residual liquid droplets to impact and adhere to the inner wall of the recovery bends due to inertia. The wall surface after adsorption is then regenerated by heating through the evaporation bends, and the resulting liquid evaporation is discharged.

[0007] Preferably, a safety valve and a liquid collection valve are installed at the top and bottom of the separation tank, respectively.

[0008] Preferably, the centrifugal assembly includes a spiral pipe and a fixed pipe. The spiral pipe is installed inside the separation tank, and the fixed pipe is installed in the middle of the spiral pipe. An exhaust pipe is installed inside the fixed pipe, and the inner wall of the fixed pipe and the outer wall of the exhaust pipe form a collection cavity. A baffle is installed on the inner wall of the separation tank below the spiral pipe.

[0009] Preferably, the recycling assembly includes a recycling fixing ring and a flow guide shroud. The flow guide shroud is installed around the outer perimeter of the recycling fixing ring, and a flow guide ball is installed at the bottom end of the recycling fixing ring. The flow guide ball is disposed inside the flow guide shroud.

[0010] Preferably, the two ends of the recovery bend are connected to the recovery fixing ring and the air outlet pipe, respectively, and an adsorption strip is installed on the outer wall of the inner bend section of the recovery bend. Multiple heating frames are installed on the outer wall of the bend section of the adsorption strip and at the location surrounding the adsorption strip.

[0011] Preferably, a pair of reset slots are provided in the heating frame, a slide rod is slidably connected in the reset slot, and an elastic strip is installed on the inner wall of the reset slot, the elastic strip being connected to the slide rod.

[0012] Preferably, a sealing cover is installed at the outer end of the slide rod, and a magnetic block is embedded in the sealing cover.

[0013] Preferably, an arc-shaped electromagnet is installed on the inner wall of the evaporation bend, and a discharge pipe is installed at the outer end of the evaporation bend, the discharge pipe being connected to the collection chamber.

[0014] Preferably, the extrusion assembly includes a protective cover, which is installed on the inner wall of the separation tank, and a servo motor is installed inside the protective cover. A rotating block is installed at the output of the servo motor. Multiple connecting rods are slidably connected in an abutment groove on the rotating block. A reciprocating block is installed at one end of each connecting rod. A water-absorbing ring is installed on the inner wall of the separation tank and outside the connecting rod.

[0015] Preferably, the shape corresponding to the abutment groove is set to an annular wavy shape.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) This scheme adds control and capture of the behavior of the separated liquid. The baffle first stabilizes and turns the airflow after centrifugal separation to achieve inertial sedimentation of medium-sized droplets. Then, the system composed of the guide hood, guide ball and recovery bend is used to collect and process the airflow that may contain splashed liquid mist. The sharp turn of the gas in the recovery bend allows those droplets that are generated by splashing, have small mass and small inertia to be efficiently captured on the outer wall of the bend. The adsorption strip further ensures that the droplets are adsorbed and locked to prevent rebound. The secondary pollutants are collected in the final stage, thereby ensuring that the outlet gas reaches a very high degree of dryness.

[0017] (2) This solution is specifically designed for the nuclear adsorption strip that captures fine droplets. It is designed with a heating evaporation regeneration module consisting of a heating frame, a sealing cover and an evaporation bend. It can be automatically started when the machine is stopped to evaporate and discharge the adsorbed liquid, so that the adsorption strip is restored to its original state. At the same time, the water absorption ring used to collect the fluid on the wall is also equipped with a squeezing component driven by a wave-shaped abutment groove, which can periodically squeeze and dehydrate, consolidating its long-term effectiveness in solving the secondary entrainment problem and ensuring the durability and stability of the separation performance.

[0020] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] like Figure 1 , Figure 2 and Figure 6 As shown in the figure, an embodiment of the present invention provides a buffer separation device for a gas compressor, comprising: a separation tank 1, a centrifugal assembly 2, and a recovery assembly 3. The separation tank 1 is equipped with an inlet 12 and an outlet 13 on both sides. The centrifugal assembly 2 is installed inside the separation tank 1 and is used to provide a flow path for the mixed gas discharged from the inlet 12, so that the mixed gas generates centrifugal force, thereby separating it into large-particle liquid and gas to be collected. The recovery assembly 3 includes multiple recovery bends 5 and multiple evaporation bends 6, with the evaporation bends 6 installed on the outside of the recovery bends 5. The recovery bends 5 are used to change the flow direction of the gas to be collected, so that the residual liquid droplets in them impact and are adsorbed onto the inner wall of the recovery bends 5 due to inertia. Then, the wall surface that has completed adsorption is heated and regenerated by the evaporation bends 6, and the generated liquid evaporation is discharged.

[0022] The purpose of this design is to deeply purify the process gas containing liquid droplets discharged from the compressor. While efficiently separating large liquid particles, it completely solves the problem of "secondary entrainment" caused by the splashing of separated liquid, thereby obtaining extremely dry compressed gas.

[0023] The main body of this device is a separation tank 1, which has an air inlet 12 on one side for receiving liquid-containing process gas and an air outlet 13 on the other side for discharging dry gas. The core working principle of the device is divided into two main stages: primary centrifugal separation and terminal fine collection and regeneration.

[0024] In the initial separation stage, centrifugal assembly 2 is mainly used. This assembly mainly includes a spiral pipe 21, whose inlet is connected to the air inlet 12. After the high-pressure liquid-containing gas enters the spiral pipe 21, it is forced to flow along the spiral path, generating a strong vortex. Based on the density difference between the gas and liquid phases, the denser droplets are thrown to the outside of the pipe under the action of centrifugal force, and finally collide with and adhere to the inner wall of the separation tank 1, achieving efficient preliminary separation of large droplets. The gas after preliminary purification then converges towards the center.

[0025] In the terminal fine collection and regeneration stage, the recovery component 3 completes the process. This component is the key to overcoming the problem of "secondary entrainment". It first collects, stabilizes and accelerates the gas from the primary separation zone through a gradually narrowing cavity composed of a flow guide shroud 32 and a flow guide ball 33, and guides it smoothly into multiple recovery bends 5.

[0026] The recovery bend 5 is designed as a flow channel with a sharp turn, forcing the gas to change direction drastically as it passes through. At this time, the small residual droplets generated by the splashing of the primary separation liquid in the gas, due to their large inertia, cannot flexibly change direction with the gas flow line, and thus collide with the inner wall of the bend section of the recovery bend 5.

[0027] To further ensure the capture effect, a specially designed adsorption strip 51 is fixed on the impact wall. It can immediately adsorb and lock the fine droplets that impact, preventing them from rebounding or falling off, thus achieving the final capture of submicron-sized droplets that are difficult to capture by traditional methods. The dry gas that has completed adsorption and purification is finally discharged from the outlet 13 through the outlet pipe 23.

[0028] Another innovation of the recycling component 3 is the integration of a self-cleaning and regeneration function. Each recycling bend 5 is fitted with an evaporation bend 6 on its outer side, and a heating frame 52 is installed at the position corresponding to the adsorption strip 51.

[0029] When the device is shut down for maintenance, the heating frame 52 can be activated to heat the adsorption strip 51, causing the adsorbed liquid to evaporate. The water vapor generated by evaporation is guided to a specific cavity in the system through the discharge pipe 62 and then discharged, thereby restoring the adsorption strip 51 to a dry state and adsorption capacity, realizing the in-situ regeneration and reuse of key consumables.

[0030] like Figure 1 As shown, a safety valve 11 and a liquid collection valve 14 are installed at the top and bottom of the separation tank 1, respectively.

[0031] In the construction of the separator 1, a safety valve 11 is installed at the top and a liquid collection valve 14 is installed at the bottom to solve the problems of pressure safety and discharge of separated products during the operation of the device, thereby ensuring the long-term stable and efficient operation of the equipment.

[0032] Specifically, the safety valve 11 is integrated at the highest point of the separator 1. Since this device processes process gas from a gas compressor, its inlet pressure may fluctuate or experience instantaneous overpressure.

[0033] Safety valve 11 is set to automatically open when the internal pressure of separation tank 1 exceeds a preset safety threshold, quickly releasing excess gas to the outside, thereby effectively preventing tank deformation, seal failure or other safety accidents caused by excessive pressure.

[0034] Meanwhile, the liquid collection valve 14 is installed at the lowest point of the bottom of the separator tank 1. After centrifugal separation by the centrifugal assembly 2 and inertial settling by the baffle 24, a large amount of liquid separated from the gas collects at the bottom of the tank under the action of gravity. The liquid collection valve 14 is used to periodically or continuously discharge the collected liquid from the system.

[0035] This not only prevents the separated liquid from accumulating excessively in the tank and occupying the effective separation space, but more importantly, it prevents the liquid from being re-entrained by the rising airflow after the liquid level at the bottom of the tank is too high, thus ensuring the dryness of the final outlet gas and maintaining the continuous and efficient separation performance of the device.

[0036] like Figures 1 to 2 As shown, the centrifugal assembly 2 includes a spiral pipe 21 and a fixed pipe 22. The spiral pipe 21 is installed inside the separation tank 1, and the fixed pipe 22 is installed in the middle of the spiral pipe 21. An exhaust pipe 23 is installed inside the fixed pipe 22, and the inner wall of the fixed pipe 22 and the outer wall of the exhaust pipe 23 form a collection cavity. A baffle plate 24 is installed on the inner wall of the separation tank 1 and below the spiral pipe 21.

[0037] The centrifugal assembly 2 constitutes the core functional unit of the buffer separation device for achieving efficient primary separation. It is integrated inside the separation tank 1 and specifically includes a spiral pipe 21, a fixed pipe 22, an exhaust pipe 23, and a baffle plate 24. All components work together to achieve multi-stage separation in a compact structure.

[0038] The spiral pipe 21 is fixedly installed in the inner cavity of the separator 1, and its inlet is connected to the air inlet 12. When compressed gas carrying droplets enters from the air inlet 12, it is forced into the spiral pipe 21.

[0039] As the gas moves along the spiral path, it generates a strong rotating flow. Based on the density difference between the gas and liquid phases, the denser droplets are thrown to the outside of the spiral pipe 21 under centrifugal force and eventually collide with and adhere to the inner wall of the separator 1, thus achieving efficient preliminary separation of large droplets. The separated gas then converges towards the central low-pressure zone of the spiral pipe 21.

[0040] At the central axis of the spiral pipe 21, a fixed pipe 22 is coaxially arranged, and an exhaust pipe 23 is coaxially installed inside the fixed pipe 22. An annular collection cavity is formed between the inner wall of the fixed pipe 22 and the outer wall of the exhaust pipe 23.

[0041] To further capture the smaller droplets remaining after centrifugation, a baffle plate 24 is installed on the inner wall of the separator 1 and on the lower side downstream of the airflow in the spiral pipe 21.

[0042] After initial separation through the spiral pipe 21, the gas moves downward and impacts the baffle plate 24, causing a sharp change in the flow direction, such as a 180° turn.

[0043] In this abrupt flow field, gas molecules, due to their small mass, easily follow the streamline and change direction, while the remaining droplets, with their greater inertia, are difficult to deflect. As a result, they break away from the mainstream and collide with the surface of the baffle 24, and then drip downwards due to gravity, thus achieving secondary fine separation based on the inertial mechanism.

[0044] In summary, the centrifugal assembly 2, through a series design of spiral centrifugal separation and baffle inertial separation, completes the stepwise removal of liquid droplets from the gas from coarse to fine in a highly integrated space. This effectively overcomes the problems of insufficient efficiency or large equipment size of traditional single separation methods, and significantly improves separation efficiency and space utilization of the device.

[0045] like Figures 4 to 9 As shown, the recovery assembly 3 includes a recovery fixing ring 31 and a flow guide 32. The flow guide 32 is installed around the outer perimeter of the recovery fixing ring 31, and a flow guide ball 33 is installed at the bottom of the recovery fixing ring 31. The flow guide ball 33 is disposed inside the flow guide 32.

[0046] The two ends of the recovery bend 5 are connected to the recovery fixing ring 31 and the air outlet pipe 23, respectively. An adsorption strip 51 is installed on the outer wall of the inner bend section of the recovery bend 5. Multiple heating frames 52 are installed on the outer wall of the bend section of the adsorption strip 51 and at the outer perimeter of the adsorption strip 51. A pair of reset grooves 54 are opened in the heating frame 52. A slide rod 56 is slidably connected in the reset groove 54. An elastic strip 55 is installed on the inner wall of the reset groove 54. The elastic strip 55 is connected to the slide rod 56. A sealing cover 53 is installed on the outer end of the slide rod 56. A magnetic block is embedded in the sealing cover 53.

[0047] An arc-shaped electromagnet 61 is installed on the inner wall of the evaporation bend 6, and a discharge pipe 62 is installed at the outer end of the evaporation bend 6, which is connected to the collection chamber.

[0048] Among them, the recovery component 3 is the core unit for fine processing and purification of gas, which is integrated into the separation tank 1 and located above the baffle 24.

[0049] It mainly consists of a recovery fixing ring 31, a flow guide hood 32, a flow guide ball 33, multiple recovery bends 5 and multiple evaporation bends 6, which work together to solve the problem of secondary entrainment of residual trace droplets in the gas after the pre-stage separation and to achieve self-recovery of the adsorption function.

[0050] Specifically, the deflector 32 is in the shape of an inverted bowl or funnel, with its large-diameter end facing downwards, so as to effectively collect the rising airflow from the area of ​​the lower baffle 24.

[0051] The recovery fixing ring 31 is installed at the top center of the flow guide shroud 32, and a flow guide ball 33 is coaxially installed at its bottom end. The flow guide ball 33 is located inside the flow guide shroud 32.

[0052] A ring-shaped cavity with a gradually narrowing cross-section is formed between the flow guide shroud 32 and the flow guide sphere 33. This tapering structure can accelerate the gas, giving it sufficient kinetic energy to enter the subsequent processing unit. At the same time, this smooth guiding effect helps stabilize the flow field and reduce the impact of airflow disturbance on the already settled liquid surface at the bottom of the tank, thereby inhibiting the re-entrainment of liquid from the source of flow field design.

[0053] The inlet ends of multiple recycling bends 5 are connected to the recycling fixing ring 31, while the outlet ends are connected to the inlet of the gas outlet pipe 23.

[0054] After the accelerated gas enters the recovery bend 5, it is forced to make a sharp turn at the bend. Due to the difference in inertia between the gas and the residual droplets in it, the droplets cannot flexibly change direction with the airflow, thus impacting and adhering to the outer wall of the bend section of the recovery bend 5.

[0055] To further ensure capture efficiency and prevent droplet bounce, an adsorption strip 51 is fixedly installed on the outer wall of the curved section. The adsorption strip 51 is made of a heat-resistant material with excellent hydrophilic or capillary properties.

[0056] Firstly, its surface properties enable it to instantly adsorb and lock droplets caused by inertial impact, effectively preventing droplets from rebounding or falling off, thus achieving efficient capture of submicron-sized droplets.

[0057] Secondly, its heat resistance ensures that the material structure remains stable and its performance does not degrade during subsequent heating and regeneration processes, thus supporting repeated heating and dehydration and reuse.

[0058] After completing inertial collision and adsorption treatment, the purified gas continues to flow along the path of the recovery bend 5, and finally flows into the gas outlet pipe 23 through its outlet end, and is discharged from the system through the gas outlet 13 connected to the gas outlet pipe 23, thereby obtaining dry and clean process gas.

[0059] When the gas is processed in the recovery bend 5, the elasticity of the elastic strip 55 drives the sealing cover 53 to remain closed, forming a seal inside the heating frame 52, effectively preventing gas from escaping from there, and ensuring the airtightness and efficiency of the separation process.

[0060] To enable online cleaning and regeneration of the adsorption strip 51 and ensure its continuous and effective adsorption capacity, the recovery component 3 is also equipped with a matching evaporation bend 6 and a heating structure, with multiple evaporation bends 6 respectively fitted on the outside of the corresponding recovery bend 5.

[0061] A heating frame 52 is installed on the outside of the recycling bend 5 at the position corresponding to the adsorption strip 51. In order to control the heating and evaporation process, a sealing cover 53 is elastically installed on the inside of each heating frame 52 through the cooperation of a reset groove 54, an elastic strip 55 installed in the groove, and a slide rod 56 slidably connected in the groove.

[0062] A magnetic block is embedded in the sealing cap 53. Correspondingly, an arc-shaped electromagnet 61 is installed at the outer end of the evaporation bend 6. The inner wall of the electromagnet is connected to a discharge pipe 62. The discharge pipe 62 is connected to the collection cavity formed between the inner wall of the fixed pipe 22 and the outer wall of the gas outlet pipe 23.

[0063] The regeneration process of the adsorption strip 51 is usually arranged during the equipment shutdown and maintenance phase. When regeneration is required, the arc electromagnet 61 is activated, and the magnetic force generated by it attracts the magnetic block on the sealing cover 53, overcoming the elastic force of the elastic strip 55 to open the sealing cover 53.

[0064] At the same time, the heating frame 52 is activated to heat the adsorption strip 51, causing the adsorbed liquid to evaporate, and the generated water vapor can enter the space of the evaporation bend 6.

[0065] The discharge of water vapor relies on the inherent pressure difference or ejection effect of the system, which is a mature existing technology. For example, in the collection chamber or related flow path connected to the outlet of the discharge pipe 62, a local negative pressure can be generated due to the main airflow, or a low-pressure drainage pipe connected to the compressor system can be set up to form a reliable suction and guidance of water vapor in the evaporation bend 6.

[0066] After water vapor is introduced into the collection chamber through the discharge pipe 62, it is eventually discharged with the main airflow of the system or through a dedicated discharge path, thereby completing the drying and regeneration of the adsorption strip 51 and restoring its adsorption performance.

[0067] This regeneration operation can be carried out simultaneously with the squeezing and dehydration operation of the squeezing component 4 on the water-absorbing ring 45, enabling efficient and centralized maintenance of all adsorption units inside the device during shutdown. The regeneration process is highly automated, requires no disassembly of parts, greatly reduces maintenance costs, and ensures the continuous operation capability of the device.

[0068] It should be added that the structural design has specific considerations to optimize the drying effect and ensure the complete regeneration of the adsorption strip 51.

[0069] The main body of the adsorption strip 51 is embedded in the curved wall of the recycling bend 5, while a portion of its structure is a protruding end that protrudes into the heating frame 52.

[0070] When the equipment is running normally and adsorbing, the droplets that collide with and adhere to the inner arc-shaped section wall of the recovery bend 5 will gradually migrate from the adsorption point and converge to the protruding end through the capillary action or surface diffusion of the adsorption strip 51 material itself.

[0071] When the regeneration process is started, the heat generated by the heating frame 52 is concentrated on the protruding end. On the one hand, the liquid adsorbed by the protruding end is directly heated and evaporated; on the other hand, the liquid stored in the arc-shaped adsorption strip 51 will continue to migrate to the protruding end, which is in a high-temperature state, and be evaporated thereafter, driven by capillary force and concentration gradient.

[0072] This method achieves the goal of deep drying of the entire adsorption strip 51 through localized and efficient heating, ensuring thorough regeneration and restoring full adsorption capacity for subsequent use cycles. The regeneration process is highly automated, requires no disassembly of parts, greatly reduces maintenance costs, and ensures the continuous operation of the device.

[0073] In summary, the recycling component 3 forms a closed-loop processing flow through the flow-guiding acceleration of the flow guide hood 32 and the flow guide ball 33, the inertial collision adsorption of the recycling bend 5 and the adsorption strip 51, and the heating evaporation regeneration of the heating frame 52, the sealing cover 53 and the evaporation bend 6 system.

[0074] This design not only completely removes residual trace amounts of liquid from the gas, ensuring the extreme dryness of the outlet gas, but also innovatively achieves online self-cleaning and long-term stable operation of the system through a regenerable adsorption strip design and a shutdown maintenance procedure that can be executed simultaneously.

[0075] like Figure 10As shown, the extrusion assembly 4 includes a protective cover 41, which is installed on the inner wall of the separation tank 1. A servo motor is installed inside the protective cover 41. A rotating block 42 is installed at the output of the servo motor. Multiple connecting rods 43 are slidably connected in the abutment groove opened on the rotating block 42. A reciprocating block 44 is installed at one end of the connecting rod 43. A water-absorbing ring 45 is installed on the inner wall of the separation tank 1 and outside the connecting rod 43. The shape of the abutment groove is set as an annular wave shape.

[0076] Among them, the extrusion component 4 is a special cleaning and recycling mechanism designed in the buffer separation device to address the problem of liquid residue on the inner wall of the separation tank 1. It is integrated into the inner wall of the separation tank 1 and converts the rotational motion into periodic radial extrusion motion, thereby achieving mechanical dehydration of the adsorbent material, ensuring that the inner wall of the device is dry, and preventing the separated liquid from being re-entrained by the airflow due to excessive adhesion to the wall surface, which would cause secondary pollution.

[0077] Specifically, the extrusion assembly 4 includes a protective cover 41 mounted on the inner wall of the separation tank 1, which encapsulates a servo motor to power the entire assembly.

[0078] The output shaft of the servo motor is connected to a rotating block 42. The rotating block 42 has a specially designed annular wave-shaped abutment groove. One end of multiple connecting rods 43 is slidably connected to this annular wave-shaped abutment groove via sliders or rollers.

[0079] When the servo motor starts, it drives the rotating block 42 to rotate at a constant speed. Since the end of the connecting rod 43 is constrained in the wavy abutment groove, the undulating contour of the groove wall forces the rotational motion of the rotating block 42 into the reciprocating linear motion of the connecting rod 43 along its axis. A reciprocating block 44 is fixedly connected to the other end of each connecting rod 43.

[0080] On the inner wall of the separator 1, an annular water-absorbing ring 45 is fixedly installed around the outer side of these reciprocating blocks 44. The water-absorbing ring 45 is made of a highly absorbent elastic porous material, such as a sponge, and is positioned directly opposite the tank wall area downstream of the spiral pipe 21. It is used to actively absorb and temporarily store the liquid that is thrown to the tank wall by centrifugal force and flows down the wall.

[0081] During operation, the servo motor drives the rotating block 42 to rotate, which in turn drives all the connecting rods 43 and the reciprocating block 44 to perform periodic radial reciprocating motion synchronously.

[0082] When the reciprocating block 44 moves towards the tank wall, it squeezes the water-absorbing ring 45 on its outer side, mechanically expelling the liquid adsorbed and stored in its pores. When the reciprocating block 44 retracts towards the center, it releases the pressure on the water-absorbing ring 45, which then returns to its original shape due to its material elasticity and is ready to adsorb the subsequent liquid flow. The expelled liquid drips to the bottom of the tank under gravity and is eventually discharged through the liquid collection valve 14.

[0083] The annular wave-shaped abutment groove transforms the single rotation drive into a smooth, synchronous multi-point reciprocating extrusion, resulting in a compact and reliable structure.

[0084] Through periodic automatic compression, the water absorption ring 45 maintains a good adsorption capacity, effectively intercepting the liquid flowing down the wall. This prevents the liquid from being torn and entrained by the high-speed airflow when it forms a continuous liquid film or accumulates and drips on the tank wall, significantly improving the purity of the final output gas and the continuous working capability of the device.

[0085] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of the invention or exceed the scope defined in the claims, all of which should fall within the protection scope of the present invention.
