A gas separation device based on ultrasonic resonance

Abstract

This invention relates to the field of gas-liquid separation technology and discloses a gas separation device based on ultrasonic resonance, including a separation tank. A gas storage frame is fixedly connected to the inner wall of the separation tank, and an air inlet pipe is connected through the inner wall of the separation tank. Four arc-shaped grooves are formed on the inner wall of the gas storage frame. Biogas enters the arc-shaped grooves, causing the biogas to collide and slowing down its flow speed. A motor is started to drive the fan-shaped frame to rotate slowly. Through the blocking component, the biogas flows to the position of the ultrasonic generator, while preventing the biogas from rising further. Then, the droplets are mixed. By slowing down the flow speed of the biogas and concentrating it in one place, the density of the tiny droplets is increased. Combined with the blocking of the biogas flow, the droplets can gather into larger droplets, making the droplets easier to settle, thus promoting the separation of droplets from biogas. This effectively prevents the biogas from flowing too fast, as high-speed airflow can easily carry large droplets, ensuring that the biogas and droplets are fully separated.

Description

Technical Field

[0001] This invention relates to the field of gas-liquid separation equipment technology, specifically a gas separation device based on ultrasonic resonance. Background Technology

[0002] Ultrasonic resonance-based gas separation devices are a technology that utilizes the vibration characteristics of ultrasonic waves to achieve efficient separation of gas mixtures. Its core principle is to use the interaction between the ultrasonic field and gas molecules to drive the separation of different gas components through resonance effect or acoustic energy. Ultrasonic resonance technology utilizes the differences in vibration characteristics of different gas molecules at specific frequencies, resulting in different directions and velocities of their motion in the sound field, thereby achieving separation. In the purification of biogas, ultrasonic vibration is often used to cause the biogas to condense into larger droplets, causing the droplets in the biogas to settle and separating the droplets from the gas.

[0003] Biogas is produced by the fermentation of degradation products, such as kitchen waste, livestock and poultry manure, and agricultural waste. Generally, the degradation products are put into a biogas digester and biogas is produced by natural fermentation. However, in areas with large temperature differences between day and night, high temperatures will accelerate biogas production. When the production increases, the biogas flow rate will increase and the airflow drag will increase. Even if ultrasonic resonance mixes the droplets, the droplets in the biogas may still be carried by the high-speed airflow and are difficult to settle, resulting in incomplete gas-liquid separation and affecting the purification of biogas. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a gas separation device based on ultrasonic resonance, including a separation tank, a gas storage frame fixedly connected to the inner wall of the separation tank, and an air inlet pipe connected through the inner wall of the separation tank.

[0005] The separation mechanism has a condensation component fixedly installed on its inner wall and a drive component installed on its top. The condensation component is used to separate liquid droplets from biogas.

[0006] A slowing mechanism, installed on the inner wall of the condensation assembly, is used to slow the flow rate of biogas; and

[0007] An expansion mechanism, located on the inner wall of the separation mechanism, accelerates the collision speed of biogas.

[0008] The inner wall of the gas storage frame has four arc-shaped grooves, and two inclined baffles are fixedly connected to the inner wall of the gas storage frame. A collection frame is slidably connected to the inner wall of the gas storage frame.

[0009] The process involves injecting biogas into the separator through an intake pipe. Then, a separation mechanism mixes the biogas droplets, causing them to settle. A deceleration mechanism slows down the flow of biogas, and finally, an expansion mechanism accelerates the collision speed of the biogas, allowing the droplets to aggregate into larger droplets and settle more easily. This promotes the separation of biogas droplets from the biogas, effectively preventing the high flow rate of biogas from carrying large droplets and ensuring thorough separation of biogas from droplets.

[0010] Preferably, the separation mechanism includes:

[0011] A condensation assembly is fixedly installed on the outer wall of the condensation assembly and on the inner wall of the separator, and is used to mix the liquid droplets in the biogas.

[0012] The drive assembly is fixedly mounted at the bottom and at the top of the separation tank, and is used to drive the rotation of the slowing mechanism;

[0013] When biogas needs to be purified, biogas is injected into the separator through the intake pipe, and then the liquid droplets in the biogas are vibrated and mixed by the vibrator in the condensation component, which promotes the sedimentation of the droplets.

[0014] Preferably, the mitigation mechanism includes:

[0015] A flow guiding component is fixedly installed on the side wall of the gas storage frame to guide the flow of biogas.

[0016] A blocking component is rotatably installed on the inner wall of the gas storage frame to block the flow of biogas.

[0017] When biogas enters the separator, it is guided by the flow guide component to separate it into two streams. The two streams collide, consuming the biogas's kinetic energy, slowing down the flow speed, and reducing the drag force on the droplets in the biogas. Then, the flow of biogas is blocked multiple times by the blocking component, giving the droplets in the biogas sufficient time to mix, allowing the droplets to gather into larger droplets and making them easier to settle.

[0018] Preferably, the expansion mechanism includes:

[0019] The discharge component is fixedly installed on the inner wall of the gas storage frame and is used to discharge the mixed droplets.

[0020] The reciprocating component is slidably mounted on the inner wall of the separator via a sliding member, and is used to compress biogas and accelerate the collision speed of biogas.

[0021] The sliding component includes a spring ring that is slidably connected to the inner wall of the separator, and a fixing bracket is fixedly connected to the inner wall of the separator;

[0022] In this process, after the droplets mix and settle, the settled droplets are discharged through the discharge component and then rise through the reciprocating component, compressing the biogas and accelerating the collision speed of the biogas. This effectively prevents the biogas droplets from being too small and requiring a long mixing time. Since the biogas will continue to be injected into the separator, if the blocking component blocks the biogas for too long, it will easily cause the pressure inside the separator to be too high. If the blocking component blocks the biogas for too short a time, it will easily cause the droplets to be difficult to mix fully.

[0023] Preferably, the condensation assembly includes an outlet pipe that runs through the inner wall of the separator, and two ultrasonic generators that are fixedly connected to the inner wall of the gas storage frame.

[0024] The operator sends biogas into the separator through the air inlet pipe. The biogas will accumulate in the separator until a large amount of biogas has accumulated.

[0025] Preferably, the drive assembly includes a motor fixedly connected to the top of the separation tank, a rotating rod rotatably connected to the inner wall of the separation tank, and the bottom output end of the motor fixedly connected to the top of the rotating rod.

[0026] Preferably, the flow guiding component includes two inclined panels that are slidably connected to the inner wall of the collection frame, and L-shaped blocks are fixedly connected to the left and right sides of the gas storage frame, with extension grooves provided on the inner walls of the two L-shaped blocks.

[0027] The biogas then enters the extension trough and the arc-shaped trough, flowing within the two arc-shaped troughs and splitting into two streams. These two streams collide at the outlet of the arc-shaped troughs, consuming the kinetic energy of the biogas and slowing its flow. The biogas then enters the gas storage frame, concentrating it within the frame. Because biogas production requires a high temperature, its high heat content causes a decrease in gas density, resulting in it flowing upwards.

[0028] Preferably, the blocking component includes a fan-shaped frame disposed on the inner wall of the gas storage frame, the top of the fan-shaped frame being fixedly connected to the bottom of the rotating rod, a fan-shaped groove being provided on the inner wall of the gas storage frame, a push rod being slidably connected to the inner wall of the gas storage frame, and the outer wall of the push rod being fixedly connected to the inner wall of the collection frame.

[0029] When biogas enters the storage frame, the motor drives the rotating rod to rotate, which in turn causes the fan-shaped frame to rotate slowly. During the rotation of the fan-shaped frame, when the protruding part of the fan-shaped frame comes into contact with the push rod, it will squeeze the push rod to descend.

[0030] Preferably, the discharge assembly includes a funnel frame fixedly connected to the inner wall of the gas storage frame, a drain pipe being connected through the top of the funnel frame, and the outer wall of the drain pipe being connected through the inner wall of the separation tank.

[0031] A spring inclined ring is slidably connected to the inner wall of the drain pipe. The top of the spring inclined ring is fixedly connected to the bottom of the push rod. The side walls of the two inclined plates are fixedly connected to the inner wall of the funnel frame.

[0032] The process involves lowering the collection frame and the spring-loaded inclined ring, allowing the ring to accumulate rebound force. This causes the collection frame to separate from the inclined baffle, removing the obstruction to the biogas. The biogas then flows to the ultrasonic generator, which activates to generate ultrasonic resonance. This vibration causes the surrounding biogas and droplets to form localized vortices, drawing droplets dispersed in different areas into the center of the vortex and mixing them. As the fan-shaped frame continues to rotate, it covers the fan-shaped groove, preventing the biogas from rising. Simultaneously, the recessed area of ​​the fan-shaped frame re-contacts the push rod, eliminating the compressive force. At this point, the rebound force of the spring-loaded inclined ring... It will release, allowing the push rod and collection frame to return to their original positions, allowing the collection frame to fit against the inclined baffle, blocking the biogas flow to the ultrasonic generator position, giving the droplets in the biogas time to mix. By slowing down the flow speed of the biogas and concentrating it in one place, the density of the tiny droplets is increased, and the energy of the ultrasonic vibration can act more concentrated on the droplets. Combined with blocking the biogas flow, it gives the droplets enough time to mix, allowing the droplets to gather into larger droplets, making the droplets easier to settle, and promoting the separation of droplets from the biogas. This effectively prevents the biogas from flowing too fast, as high-speed airflow can easily carry large droplets, thus ensuring the complete separation of biogas and droplets.

[0033] As the fan-shaped frame continues to rotate, it removes its obstruction to the fan-shaped groove, allowing biogas to flow upwards through the groove and enter the gas outlet pipe. The biogas is then discharged through the outlet pipe. Simultaneously, the protruding part of the fan-shaped frame again compresses the push rod and the collection frame, causing untreated biogas to move to the ultrasonic generator. This process repeats, separating the droplets in the biogas. The mixed droplets fall into the collection frame and accumulate. As the collection frame descends, it separates from the inclined plate, allowing the droplets to slide down the inclined surfaces into the funnel frame. From there, they enter the drain pipe. As the push rod lowers the collection frame, it also causes the spring inclined ring to descend and separate from the inclined surface of the drain pipe, removing its obstruction of the droplets, which are then discharged through the drain pipe.

[0034] Preferably, the reciprocating assembly includes a rocker arm rotatably connected to the outer wall of the fixed frame, and a squeezing rod slidably connected to the inner wall of the gas storage frame, with the top of the squeezing rod fixedly connected to the bottom of the collection frame;

[0035] The outer wall of the extrusion rod is slidably connected to the inner wall of the funnel frame, and the outer wall of the extrusion rod is slidably connected to the inner wall of the spring ring.

[0036] As the collection frame descends, it causes the squeezing rod to descend as well. The squeezing rod then pushes the rocker arm to rotate, causing the side of the rocker arm in contact with the squeezing rod to descend while the other side rises. The rising side pushes the spring ring upward, allowing the spring ring to accumulate rebound force. The spring ring then squeezes the biogas flow in the separator, accelerating the flow speed of the biogas and propelling it into the arc-shaped groove at a faster speed. This enhances the collision effect. During the accelerated impact, the relative kinetic energy of the droplets is significantly increased, enough to overcome the limitation of the repulsive force on the droplet surface. This allows some droplets to mix when the biogas collides, making it easier for larger droplets to mix with smaller droplets during subsequent ultrasonic vibration. This accelerates the mixing speed of subsequent droplets and effectively prevents the biogas droplets from being too small and requiring a long mixing time. Since biogas is continuously injected into the separator, if the fan-shaped frame blocks the biogas for too long, it can easily cause excessive pressure in the separator. If the fan-shaped frame blocks the biogas for too short a time, it can easily cause the droplets to not mix sufficiently.

[0037] The present invention has the following beneficial effects:

[0038] (1) When using this invention, the operator sends biogas into the separator through the air inlet pipe. The biogas will enter the arc-shaped groove and collide at the outlet of the arc-shaped groove, slowing down the flow speed of the biogas and concentrating the biogas in the gas storage frame. The motor drives the fan-shaped frame to rotate slowly. Through the blocking component, the biogas will flow to the position of the ultrasonic generator. Then, the ultrasonic generator is started to generate ultrasonic resonance, which mixes the droplets. As the fan-shaped frame continues to rotate, it will cover the fan-shaped groove and block the biogas from rising. By slowing down the flow speed of the biogas and concentrating it in one place, the density of the tiny droplets is higher, and the energy of the ultrasonic vibration can be more concentrated on the droplets. Combined with blocking the flow of biogas, it gives the droplets enough time to mix, allowing the droplets to gather into larger droplets, making the droplets easier to settle, and promoting the separation of the droplets from the biogas. This effectively prevents the biogas from flowing too fast and the high-speed airflow from carrying large droplets, thus ensuring the separation of the biogas from the droplets.

[0039] (2) When the collection frame descends, the extrusion rod will descend, and the extrusion rod will push the rocker to rotate. Through the reciprocating assembly, the spring ring will squeeze the biogas flow in the separation tank, and push the biogas into the arc groove at a faster speed, thereby enhancing the collision effect and allowing some droplets to mix. This makes it easier for larger droplets to mix with smaller droplets during subsequent ultrasonic vibration, thus accelerating the mixing speed of subsequent droplets. This effectively prevents the biogas droplets from being too small and requiring a long mixing time. Since the biogas will be continuously injected into the separation tank, if the fan-shaped frame blocks the biogas for too long, the pressure in the separation tank will be too high. If the fan-shaped frame blocks the biogas for too short a time, the droplets will be difficult to mix fully.

[0040] (3) The present invention guides biogas into the arc-shaped groove at the bottom through the extension groove inside the L-shaped block, so that the opening position of the extension groove and the arc-shaped groove at the top are at the same height, and the size of the extension groove is larger than that of the arc-shaped groove. This reduces the air intake resistance and makes it easier for the gas to flow into the bottom arc-shaped groove, guiding the biogas in. This makes the amount of biogas entering the two arc-shaped grooves more uniform, effectively preventing the biogas, which has a certain temperature, from accumulating upward in the separator. This would easily result in a higher biogas content at the top of the separator and a lower content at the bottom. The arc-shaped groove at the top has a higher biogas content and a faster flow rate, while the arc-shaped groove at the bottom has a lower content and a slower flow rate. This makes it difficult for the two airflows to effectively counteract each other, affecting the deceleration of the gas. At the same time, it will also affect the initial mixing of the liquid droplets in the biogas.

[0041] (4) When the biogas production is low, the present invention blocks part of the biogas, causing the biogas to accumulate in the separator, which increases the local biogas concentration. This results in more biogas near the ultrasonic generator. The reciprocating component accelerates the flow speed of biogas in the arc-shaped trough, making the droplets easier to mix. This effectively prevents the biogas droplets from being too dispersed and difficult to mix when the biogas content is low, which would affect the sedimentation of the droplets and the separation of the droplets in the biogas. In addition, the inclined baffle blocks the biogas at the outlet of the arc-shaped trough, and at the same time, causes the droplets to fall into the collection frame. This effectively prevents the two streams of biogas from colliding and becoming too turbulent. When the droplets fall at this position, the condensed droplets are easily dispersed again by the turbulent airflow. Attached Figure Description

[0055] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] Example 1, please refer to Figures 1-4 The present invention is a gas separation device based on ultrasonic resonance, including a separation tank 111, a gas storage frame 114 fixedly connected to the inner wall of the separation tank 111, and an air inlet pipe 112 throughly connected to the inner wall of the separation tank 111.

[0057] The separation mechanism 1 has a condensation component 11 fixedly installed on its inner wall and a drive component 12 installed on its top. The condensation component 11 is used to separate liquid droplets in biogas.

[0058] Slowing mechanism 2, installed on the inner wall of condensation assembly 11, is used to slow down the flow rate of biogas; and

[0059] The expansion mechanism 3 is located on the inner wall of the separation mechanism 1, which accelerates the collision speed of biogas.

[0060] Four arc-shaped grooves 211 are provided on the inner wall of the gas storage frame 114, and two inclined baffles 212 are fixedly connected to the inner wall of the gas storage frame 114. A collection frame 213 is slidably connected to the inner wall of the gas storage frame 114.

[0061] In this process, biogas is injected into the separator 111 through the air inlet pipe 112. Then, the liquid droplets in the biogas are mixed by the separation mechanism 1, allowing the droplets to settle. Next, the flow rate of the biogas is slowed down by the deceleration mechanism 2. Finally, the collision speed of the biogas is accelerated by the expansion mechanism 3, allowing the droplets to gather into larger droplets, making it easier for the droplets to settle. This promotes the separation of the liquid droplets from the biogas, effectively preventing the biogas from flowing too fast and easily carrying large droplets, thus ensuring that the biogas and liquid droplets are fully separated.

[0062] Separation mechanism 1 includes:

[0063] A condensation component 11 is fixedly installed on its outer wall and on the inner wall of the separator 111, and is used to mix the liquid droplets in the biogas.

[0064] The bottom of the drive assembly 12 is fixedly disposed with the top of the separation tank 111, and is used to drive the deceleration mechanism 2 to rotate;

[0065] When biogas needs to be purified, biogas is injected into the separator 111 through the air inlet pipe 112, and then the liquid droplets in the biogas are vibrated and mixed by the vibrator in the condensation component 11, which promotes the sedimentation of the liquid droplets.

[0066] Mitigation mechanism 2 includes:

[0067] The flow guiding component 21 is fixedly installed on the side wall of the gas storage frame 114 to guide the flow of biogas.

[0068] The blocking component 22 is rotatably disposed on the inner wall of the gas storage frame 114 to guide the biogas out.

[0069] When biogas enters the separator 111, the flow of biogas is guided by the flow guide component 21, which separates the biogas into two streams. The two streams collide, consuming the kinetic energy of the biogas, slowing down the flow speed of the biogas, and reducing the drag force on the droplets in the biogas. Then, the flow of biogas is blocked multiple times by the blocking component 22, giving the droplets in the biogas sufficient time to mix, allowing the droplets to gather into larger droplets and making the droplets easier to settle.

[0070] Expansion Unit 3 includes:

[0071] Discharge assembly 31 is fixedly installed on the inner wall of the gas storage frame 114 and is used to discharge the mixed droplets.

[0072] The reciprocating component 32 is slidably disposed on the inner wall of the separator 111 via a sliding member, and is used to compress biogas and accelerate the collision speed of biogas.

[0073] The sliding component includes a spring ring 321 that is slidably connected to the inner wall of the separator 111, and a fixing bracket 322 is fixedly connected to the inner wall of the separator 111.

[0074] In this process, after the droplets mix and settle, the settled droplets are discharged through the discharge component 31 and then rise through the reciprocating component 32, compressing the biogas and accelerating the collision speed of the biogas. This effectively prevents the biogas droplets from being too small and requiring a long mixing time. Since the biogas will continue to be injected into the separator 111, if the blocking component 22 blocks the biogas for too long, it will easily cause the pressure inside the separator 111 to be too high. If the blocking component 22 blocks the biogas for too short a time, it will easily cause the droplets to be difficult to mix fully.

[0075] Example 2, please refer to Figures 1-10 The present invention is a gas separation device based on ultrasonic resonance. Based on Example 1, the condensation component 11 includes an outlet pipe 113 that is connected through the inner wall of the separation tank 111, and two ultrasonic generators 115 are fixedly connected to the inner wall of the gas storage frame 114.

[0076] The operator sends biogas into the separator 111 through the air inlet pipe 112. The biogas will accumulate in the separator 111 until a large amount of biogas has accumulated.

[0077] The drive assembly 12 includes a motor 121 fixedly connected to the top of the separation tank 111, a rotating rod 122 rotatably connected to the inner wall of the separation tank 111, and the bottom output end of the motor 121 fixedly connected to the top of the rotating rod 122.

[0078] The flow guiding component 21 includes two inclined panels 214 that are slidably connected to the inner wall of the collection frame 213. L-shaped blocks 215 are fixedly connected to the left and right sides of the gas storage frame 114. Extension grooves 216 are provided on the inner walls of the two L-shaped blocks 215.

[0079] The biogas will then enter the extension trough 216 and the arc-shaped trough 211, allowing the biogas to flow within the two arc-shaped troughs 211, splitting the biogas into two streams. The two streams of biogas will collide at the outlet of the arc-shaped trough 211, consuming the kinetic energy of the biogas and slowing down its flow speed. The biogas will then enter the gas storage frame 114, concentrating it within the frame. Because biogas requires a high temperature to be produced, it has a high heat content, resulting in a lower gas density and causing it to flow upwards.

[0080] The blocking component 22 includes a fan-shaped frame 221 disposed on the inner wall of the gas storage frame 114. The top of the fan-shaped frame 221 is fixedly connected to the bottom of the rotating rod 122. A fan-shaped groove 222 is provided on the inner wall of the gas storage frame 114. A push rod 223 is slidably connected to the inner wall of the gas storage frame 114. The outer wall of the push rod 223 is fixedly connected to the inner wall of the collection frame 213.

[0081] When biogas enters the gas storage frame 114, the motor 121 drives the rotating rod 122 to rotate, which in turn causes the fan-shaped frame 221 to rotate slowly. During the rotation of the fan-shaped frame 221, when the protruding part of the fan-shaped frame 221 contacts the push rod 223, it will squeeze the push rod 223 to descend.

[0082] The discharge assembly 31 includes a funnel frame 311 fixedly connected to the inner wall of the gas storage frame 114, and a drain pipe 312 is connected through the top of the funnel frame 311. The outer wall of the drain pipe 312 is connected through the inner wall of the separation tank 111.

[0083] A spring inclined ring 313 is slidably connected to the inner wall of the drain pipe 312. The top of the spring inclined ring 313 is fixedly connected to the bottom of the push rod 223. The side walls of the two inclined plates 214 are fixedly connected to the inner wall of the funnel frame 311.

[0084] The process involves lowering the collection frame 213 and the spring inclined ring 313, allowing the spring inclined ring 313 to accumulate rebound force, separating the collection frame 213 from the inclined baffle 212, thus removing the obstruction to the biogas. The biogas then flows to the position of the ultrasonic generator 115. The ultrasonic generator 115 is then activated to generate ultrasonic resonance, and the vibration causes the surrounding biogas and droplets to form a local vortex. This vortex draws droplets dispersed in different areas into the center of the vortex, achieving mixing between the droplets. As the fan-shaped frame 221 continues to rotate, it covers the fan-shaped groove 222, preventing the biogas from rising. Simultaneously, the recessed position of the fan-shaped frame 221 contacts the push rod 223 again, eliminating the squeezing force. At this point, the spring... The rebound force of the inclined ring 313 will be released, allowing the push rod 223 and the collection frame 213 to return to their original positions, and the collection frame 213 to fit against the inclined baffle 212, blocking the biogas from flowing to the position of the ultrasonic generator 115, giving the droplets in the biogas time to mix. By slowing down the flow speed of the biogas and concentrating it in one place, the density of the tiny droplets is increased, and the energy of the ultrasonic vibration can be more concentrated on the droplets. Combined with blocking the flow of biogas, giving the droplets enough time to mix, the droplets can gather into larger droplets, making the droplets easier to settle, promoting the separation of droplets from biogas, effectively preventing the biogas from flowing too fast and the high-speed airflow from carrying large droplets, so that the biogas and droplets are fully separated.

[0085] As the sector frame 221 continues to rotate, it removes its obstruction of the sector groove 222, allowing biogas to flow upwards through the groove and into the outlet pipe 113. The biogas is then discharged through the outlet pipe 113. Simultaneously, the protruding part of the sector frame 221 again compresses the push rod 223 and the collection frame 213, causing untreated biogas to move to the position of the ultrasonic generator 115. This process repeats, separating droplets from the biogas. The mixed droplets then fall onto the collection frame. Inside the collection frame 213, the droplets gather. When the collection frame 213 descends, it separates from the inclined plate 214. At this time, the droplets slide down the inclined surfaces of both into the funnel frame 311, and then enter the drain pipe 312 through the funnel frame 311. When the push rod 223 pushes the collection frame 213 down, it also causes the spring inclined ring 313 to descend and separate from the inclined surface of the drain pipe 312, thus removing the obstruction to the droplets. The droplets then drain out through the drain pipe 312.

[0086] The reciprocating assembly 32 includes a rocker arm 323 rotatably connected to the outer wall of the fixed frame 322, and a squeezing rod 324 slidably connected to the inner wall of the gas storage frame 114. The top of the squeezing rod 324 is fixedly connected to the bottom of the collection frame 213.

[0087] The outer wall of the extrusion rod 324 is slidably connected to the inner wall of the funnel frame 311, and the outer wall of the extrusion rod 324 is slidably connected to the inner wall of the spring ring 321.

[0088] When the collection frame 213 descends, it causes the squeezing rod 324 to descend as well. The squeezing rod 324 then pushes the rocker arm 323 to rotate, causing the side of the rocker arm 323 in contact with the squeezing rod 324 to descend while the other side rises. The rising side pushes the spring ring 321 upward, causing the spring ring 321 to accumulate rebound force. The spring ring 321 then squeezes the biogas flow in the separator 111, accelerating the flow speed of the biogas and propelling it into the arc-shaped groove 211 at a faster speed. This enhances the collision effect and accelerates the relative impact of the droplets. The significantly enhanced kinetic energy is sufficient to overcome the limitations of the repulsive force on the surface of the droplets, enabling some droplets to mix when biogas collides. This allows larger droplets to mix more easily with smaller droplets during subsequent ultrasonic vibration, accelerating the mixing speed of subsequent droplets. This effectively prevents the biogas droplets from being too small and requiring a long mixing time. Since biogas is continuously injected into the separator 111, if the fan-shaped frame 221 blocks the biogas for too long, it can easily cause excessive pressure in the separator 111. If the blocking time of the fan-shaped frame 221 is too short, it can easily cause the droplets to be difficult to mix fully.

[0089] The number of the above components is not limited. Those skilled in the art can set it freely according to actual needs, as long as the above components are installed at the corresponding component connection positions.

[0090] A specific application of this embodiment is as follows: When using this invention, the operator sends biogas into the separator 111 through the air inlet pipe 112. The biogas will accumulate in the separator 111 until a large amount of biogas has accumulated. Then, the biogas will enter the extension groove 216 and the arc-shaped groove 211, allowing the biogas to flow in the two arc-shaped grooves 211, splitting the biogas into two streams. The two streams of biogas will collide at the outlet of the arc-shaped groove 211, consuming the kinetic energy of the biogas and slowing down its flow speed. The biogas will then enter the gas storage frame 114, concentrating the biogas in the gas storage frame 114. Since biogas production requires... The biogas requires a higher temperature, resulting in a higher heat content and a lower gas density, causing it to rise. When the biogas enters the storage frame 114, the motor 121 drives the rotating rod 122 to rotate, which in turn causes the fan-shaped frame 221 to rotate slowly. During the rotation of the fan-shaped frame 221, when the protruding part of the fan-shaped frame 221 contacts the push rod 223, it will squeeze the push rod 223 to descend, causing the collection frame 213 and the spring inclined ring 313 to descend. This allows the spring inclined ring 313 to accumulate rebound force, causing the collection frame 213 to separate from the inclined baffle 212, thus removing the obstruction to the biogas.

[0091] The biogas then flows to the ultrasonic generator 115. The ultrasonic generator 115 is then activated to generate ultrasonic resonance. The vibration causes the surrounding biogas and droplets to form localized vortices, drawing droplets dispersed in different areas into the center of the vortex, thus achieving mixing between the droplets. As the fan-shaped frame 221 continues to rotate, it covers the fan-shaped groove 222, preventing the biogas from rising. Simultaneously, the concave position of the fan-shaped frame 221 contacts the push rod 223 again, eliminating the compressive force. At this point, the restoring force of the spring inclined ring 313 is released, allowing the push rod 223 to return to its original position relative to the collection frame 213. The collection frame 213 is fitted with the inclined baffle 212 to block the biogas from flowing to the position of the ultrasonic generator 115, giving the droplets in the biogas time to mix. By slowing down the flow speed of the biogas and concentrating it in one place, the density of the tiny droplets is increased, and the energy of the ultrasonic vibration can be more concentrated on the droplets. Combined with blocking the flow of biogas, the droplets are given enough time to mix, allowing the droplets to gather into larger droplets, making the droplets easier to settle, and promoting the separation of droplets from biogas. This effectively prevents the biogas from flowing too fast, as high-speed airflow can easily carry large droplets, thus ensuring the complete separation of biogas from droplets.

[0092] As the sector-shaped frame 221 continues to rotate, it removes its obstruction of the sector-shaped groove 222, allowing biogas to flow upwards through the groove and into the outlet pipe 113. The biogas is then discharged through the outlet pipe 113. Simultaneously, the protruding part of the sector-shaped frame 221 again compresses the push rod 223 and the collection frame 213, causing the untreated biogas to move to the position of the ultrasonic generator 115. This process repeats, separating the droplets in the biogas, and the mixed droplets fall off. The droplets gather in the collection frame 213. When the collection frame 213 descends, it separates from the inclined plate 214. At this time, the droplets slide down the inclined surfaces of both into the funnel frame 311 and enter the drain pipe 312. When the push rod 223 pushes the collection frame 213 down, it also causes the spring inclined ring 313 to descend and separate from the inclined surface of the drain pipe 312, thus removing the obstruction to the droplets. The droplets will then be discharged through the drain pipe 312.

[0093] Secondly, when the collection frame 213 descends, it drives the squeezing rod 324 to descend as well. The squeezing rod 324 pushes the rocker arm 323 to rotate, causing the side of the rocker arm 323 in contact with the squeezing rod 324 to descend while the other side rises. The rising side pushes the spring ring 321 to rise, allowing the spring ring 321 to accumulate rebound force. The spring ring 321 then squeezes the biogas flow in the separator 111, accelerating the biogas flow speed and pushing the biogas into the arc-shaped groove 211 at a faster speed, thereby enhancing the collision effect and accelerating the relative impact of the droplets. The kinetic energy is significantly enhanced, which is sufficient to overcome the limitation of the repulsive force on the surface of the droplets. This allows some droplets to mix when biogas collides, making it easier for larger droplets to mix with smaller droplets during subsequent ultrasonic vibration. This accelerates the mixing speed of subsequent droplets and effectively prevents the biogas droplets from being too small and requiring a long mixing time. Since biogas is continuously injected into the separator 111, if the fan-shaped frame 221 blocks the biogas for too long, it will easily cause the pressure inside the separator 111 to be too high. If the blocking time of the fan-shaped frame 221 is too short, it will be difficult for the droplets to mix fully.

[0094] Secondly, the biogas is guided into the bottom arc-shaped groove 211 by the extension groove 216 inside the L-shaped block 215. This ensures that the opening height of the extension groove 216 and the top arc-shaped groove 211 are at the same height, and the size of the extension groove 216 is larger than that of the arc-shaped groove 211. This reduces the air intake resistance, making it easier for the gas to flow into the bottom arc-shaped groove 211. This guides the biogas into the groove, making the amount of biogas entering the two arc-shaped grooves 211 more uniform. This effectively prevents the biogas, which has a certain temperature, from accumulating upwards in the separator 111. This would result in a higher biogas content at the top of the separator 111 and a lower content at the bottom. The top arc-shaped groove would have a higher biogas content and a faster flow rate, while the bottom arc-shaped groove would have a lower content and a slower flow rate. This would make it difficult for the two airflows to effectively counteract each other, affecting the deceleration of the gas. At the same time, it would also affect the initial mixing of the biogas droplets.

[0095] Secondly, by blocking part of the biogas, the droplets in that part of the biogas are separated, causing the biogas to accumulate in the separator 111 and the pressure to increase. When the biogas output is low, the biogas accumulates in the separator 111, which increases the local biogas concentration. This results in more biogas near the ultrasonic generator 115. In conjunction with the reciprocating component 32, the flow speed of biogas in the arc-shaped groove 211 is accelerated, increasing the local biogas concentration and making it easier for the droplets to mix. This effectively prevents the biogas droplets from being too dispersed and difficult to mix when the biogas content is low, which would affect the sedimentation of the droplets and the separation of the droplets in the biogas. In addition, the inclined baffle 212 blocks the biogas at the outlet of the arc-shaped groove 211, while causing the droplets to fall into the collection frame 213. This effectively prevents the two streams of biogas from colliding and becoming too turbulent. When the droplets fall at this position, the condensed droplets are easily dispersed again by the turbulent airflow.
