Description

TECHNICAL FIELD

[0001] The application relates to the technical field of gas-liquid separation equipment, in particular to a gas separation device based on ultrasonic resonance. BACKGROUND

[0002] The gas separation device based on ultrasonic resonance is a technology for efficiently separating a gas mixture by using the vibration characteristics of ultrasonic waves, and the core principle is to use the resonance effect or acoustic energy to drive the separation of different gas components by the interaction between the ultrasonic field and the gas molecules. The ultrasonic resonance technology uses the difference in vibration characteristics of different gas molecules at a specific frequency, so that the motion direction and speed of the gas molecules in the sound field are different, thereby realizing separation. When purifying biogas, the ultrasonic vibration method is often used to promote the condensation of liquid droplets in the biogas into larger droplets, so that the liquid droplets in the biogas are separated from the gas.

[0003] Biogas is produced by fermentation of degradation materials such as kitchen waste, livestock manure and crop waste. The degradation materials are generally placed in a biogas fermentation tank and biogas is produced by natural fermentation. However, in areas with large diurnal temperature differences, the production of biogas is accelerated when the temperature is high. When the production increases, the flow rate of biogas increases and the drag force of the airflow increases. Even if the ultrasonic resonance mixes the liquid droplets, the liquid 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

[0004] To solve the above technical problems, the application provides a gas separation device based on ultrasonic resonance, which comprises 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] A separation mechanism is provided, and a condensation assembly is fixedly arranged on the inner wall of the separation mechanism. A driving assembly is installed on the top of the separation mechanism, and the condensation assembly is used to separate liquid droplets in the biogas.

[0006] A slowing mechanism is installed on the inner wall of the condensation assembly and is used to slow down the flow speed of the biogas.

[0007] An expansion mechanism is located on the inner wall of the separation mechanism and is used to accelerate the collision speed of the biogas.

[0008] Four arc-shaped grooves are formed in the inner wall of the gas storage frame, two inclined baffles are fixedly connected to the inner wall of the gas storage frame, and a collection frame is slidably connected to the inner wall of the gas storage frame.

[0009] Among them, biogas is injected into the separation tank through the air inlet pipe. After that, the droplets in the biogas are mixed through the separation mechanism to allow the droplets to settle. The flow speed of the biogas is then slowed down by the deceleration mechanism. Finally, the collision speed of the biogas is accelerated by the expansion mechanism, so that the droplets can gather into larger droplets, making it easier for the droplets to settle, prompting the droplets in the biogas to separate from the biogas, effectively preventing the biogas flow from being too fast. The high-speed airflow is prone to carrying larger droplets, so that the biogas and the droplets are fully separated.

[0010] Preferably, the separation mechanism comprises:

[0011] A condensation assembly is fixedly arranged at the outer wall of the condensation assembly and the inner wall of the separation tank, and is used to mix the liquid droplets in the biogas;

[0012] A driving assembly, the bottom of which is fixedly arranged on the top of the separation tank, and is used to drive the deceleration mechanism to rotate;

[0013] When biogas needs to be purified, the biogas is injected into the separation tank through the air inlet pipe, and then passes through the vibrator in the condensation component to vibrate and mix the droplets in the biogas, causing the droplets to settle.

[0014] Preferably, the mitigation mechanism comprises:

[0015] A flow guide assembly is fixedly arranged on the side wall of the gas storage frame to guide the flow of biogas;

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

[0017] Among them, when the biogas enters the separation tank, the biogas flow is guided by the guide component, and the biogas is separated into two streams, which are made to collide with each other, consume the kinetic energy of the biogas, slow down the flow speed of the biogas, and reduce the drag force on the droplets in the biogas. Afterwards, the biogas flow is blocked multiple times by the blocking component, giving the droplets in the biogas time to fully mix, so that the droplets can gather into larger droplets, making it easier for the droplets to settle.

[0018] Preferably, the expansion mechanism includes:

[0019] A discharge assembly is fixedly arranged on the inner wall of the gas storage frame and is used to discharge the mixed liquid droplets;

[0020] A reciprocating assembly is slidably arranged on the inner wall of the separation tank through a sliding member, and is used to squeeze the biogas and accelerate the collision speed of the biogas;

[0021] The sliding member includes a spring ring slidably connected to the inner wall of the separation tank, and a fixing frame is fixedly connected to the inner wall of the separation tank;

[0022] Among them, when the droplets are mixed and settled, the settled droplets are discharged through the discharge component, and then rise through the reciprocating component to squeeze the biogas, accelerate the collision speed of the biogas, and effectively prevent the biogas from being too small and taking a long time to mix. Since the biogas will continue to be injected into the separation tank, the blocking component blocks the biogas for too long, which may easily cause the pressure in the separation tank to be too high. The blocking component blocks for a short time, which may easily cause the droplets to be difficult to fully mix.

[0023] Preferably, the condensation assembly includes an air outlet pipe connected to the inner wall of the separation tank, and two ultrasonic generators are fixedly connected to the inner wall of the gas storage frame;

[0024] The operator sends the biogas into the separation tank through the air inlet pipe, and the biogas will gather in the separation tank until more biogas is gathered.

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

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

[0027] Among them, the biogas will enter the extension trough and the arc trough, allowing the biogas to flow in the two arc troughs and split into two streams. The two streams of biogas will collide at the outlet of the arc trough, consuming the kinetic energy of the biogas and slowing down the flow rate of the biogas. The biogas will then enter the gas storage frame and concentrate in the gas storage frame. Since a higher temperature is required for the generation of biogas, the heat of the biogas is higher, which causes the gas density to decrease and it will flow upward.

[0028] Preferably, the blocking assembly includes a fan-shaped frame arranged on the inner wall of the gas storage frame, the top of the fan-shaped frame is fixedly connected to the bottom of the rotating rod, a fan-shaped groove is opened on the inner wall of the gas storage frame, a push rod is slidably connected to the inner wall of the gas storage frame, and the outer wall of the push rod is fixedly connected to the inner wall of the collection frame;

[0029] Among them, when the biogas enters the gas storage frame, the rotating rod is driven to rotate by starting the motor, so that the fan-shaped frame rotates slowly. During the rotation process of the fan-shaped frame, when the protruding position of the fan-shaped frame contacts the push rod, it will squeeze the push rod down.

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

[0031] A spring bevel ring is slidably connected to the inner wall of the discharge pipe, the top of the spring bevel ring is fixedly connected to the bottom of the push rod, and the side walls of the two bevel panels are fixedly connected to the inner wall of the funnel frame;

[0032] Among them, the collection frame and the spring bevel ring are driven to descend, and the spring bevel ring accumulates rebound force, so that the collection frame is separated from the bevel baffle, and the obstruction to the biogas is eliminated. The biogas will flow to the position of the ultrasonic generator. After that, the ultrasonic generator is started to generate ultrasonic resonance. The vibration drives the surrounding biogas and droplets to form a local vortex, and the droplets scattered in different areas are drawn into the vortex center to achieve mixing of droplets between areas. As the fan-shaped frame continues to rotate, the fan-shaped frame will cover the fan-shaped groove to block the biogas from rising. At the same time, the concave position of the fan-shaped frame will contact the push rod again, and the squeezing force on it will disappear. At this time, the rebound force of the spring bevel ring will be It will release, allowing the push rod and the collection frame to return to their original positions, allowing the collection frame to fit with the inclined baffle, blocking the flow of biogas to the position of the ultrasonic generator, giving time for the droplets in the biogas to mix, and by slowing down the flow of biogas, concentrating the biogas in one place, making the density of tiny droplets higher, and the energy of ultrasonic vibration can act more concentratedly on the droplets, cooperating with blocking the flow of biogas, giving the droplets time to fully mix, so that the droplets can gather into larger droplets, making it easier for the droplets to settle, and promoting the separation of the droplets in the biogas from the biogas, effectively preventing the biogas flow from being too fast, and the high-speed airflow easily carrying larger droplets, so that the biogas and the droplets are fully separated;

[0033] As the fan-shaped frame continues to rotate, the fan-shaped frame will remove the obstruction to the fan-shaped groove, and the biogas will flow upward through the fan-shaped groove, enter the air outlet pipe, and be discharged through the air outlet pipe. At the same time, the protruding position of the fan-shaped frame will squeeze the push rod and the collecting frame to descend again, so that the untreated biogas moves to the position of the ultrasonic generator, and so on. The droplets in the biogas are separated. At the same time, the mixed droplets will fall into the collecting frame and gather in the collecting frame. When the collecting frame descends, the collecting frame will be separated from the inclined panel. At this time, the droplets will slide along the inclined surfaces of the two and fall into the funnel frame. Through the funnel frame, it enters the drain pipe. When the push rod pushes the collection frame to descend, the spring inclined surface ring will also descend and separate from the inclined surface of the drain pipe, thereby removing the obstruction to the droplets, and the droplets will be discharged through the drain pipe.

[0034] Preferably, the reciprocating assembly includes a seesaw rotatably connected to the outer wall of the fixed frame, an extrusion rod is slidably connected to the inner wall of the gas storage frame, and the top of the extrusion rod is 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] Among them, when the collecting frame descends, it will drive the squeezing rod to descend, and the squeezing rod will push the seesaw to rotate, so that the side of the seesaw in contact with the squeezing rod will descend and the other side will rise. The rising side will push the spring ring to rise, so that the spring ring will accumulate rebound force, and the spring ring will squeeze the flow of biogas in the separation tank, accelerate the flow rate of biogas, and push the biogas into the arc groove at a faster speed, thereby enhancing the collision effect. During the accelerated collision, the relative kinetic energy of the droplets is significantly improved, which is enough to break through the limitation of the surface repulsive force of the droplets, and can promote the mixing of some droplets when the biogas collides, so that during the subsequent ultrasonic vibration, larger droplets can be more easily mixed with smaller droplets, accelerating the mixing speed of subsequent droplets, and effectively preventing the droplets in the biogas from being small and taking a long time to mix. Since the biogas will continue to be injected into the separation tank, the fan-shaped frame blocks the biogas for too long, which may easily cause the pressure in the separation tank to be too high. The fan-shaped frame blocks for a short time, which may easily cause the droplets to be difficult to fully mix.

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

[0038] (1) When the present invention is used, the operator sends the biogas into the separation tank through the air inlet pipe, and the biogas will enter the arc groove, allowing the biogas to collide at the outlet position of the arc groove, slowing down the flow speed of the biogas, and concentrating the biogas in the gas storage frame. By starting the motor to drive the fan-shaped frame to rotate slowly, the biogas will flow to the position of the ultrasonic generator through the blocking component. After that, the ultrasonic generator is started to generate ultrasonic resonance to mix the droplets. As the fan-shaped frame continues to rotate, the fan-shaped frame will cover the fan-shaped groove and block the biogas from rising. By slowing down the flow speed of the biogas, the biogas is concentrated in one place, making the density of the tiny droplets higher, and the energy of the ultrasonic vibration can act more concentratedly on the droplets, cooperating with blocking the flow of biogas, giving the droplets time to fully mix, so that the droplets can gather larger droplets, making it easier for the droplets to settle, prompting the droplets in the biogas to separate from the biogas, and effectively preventing the biogas flow rate from being too fast. The high-speed airflow is easy to carry larger droplets to flow, so that the biogas and the droplets are fully separated.

[0039] (2) When the collecting frame of the present invention descends, it will drive the squeezing rod to descend, and the squeezing rod will push the seesaw to rotate. Through the reciprocating assembly, the spring ring squeezes the biogas flow in the separation tank, pushing the biogas into the arc groove at a faster speed, thereby enhancing the collision effect, allowing some droplets to mix, so that during subsequent ultrasonic vibrations, larger droplets can be more easily mixed with smaller droplets, accelerating the mixing speed of subsequent droplets, and effectively preventing the biogas droplets from being small and taking a long time to mix. Since biogas will continue to be injected into the separation tank, the fan-shaped frame blocks the biogas for too long, which can easily cause the pressure in the separation tank to be too high. The fan-shaped frame blocks for a short time, which can easily cause the droplets to be difficult to fully mix.

[0040] (3) The present application guides biogas through the L-shaped block extension groove into the arc-shaped groove at the bottom, so that the extension groove and the opening position of 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, which can reduce the gas inlet resistance and make the gas flow into the bottom arc-shaped groove more easily, guide the entry of biogas, make the amount of biogas entering the two arc-shaped grooves tend to be uniform, effectively prevent the biogas with a certain temperature from gathering upward in the separation tank, which is easy to cause the biogas content at the top of the separation tank to be more, the bottom to be less, the biogas content in the arc-shaped groove at the top to be more, the flow rate to be faster, the content in the bottom arc-shaped groove to be less, the flow rate to be slower, so that the two gas flows are difficult to effectively offset, affecting the deceleration of the gas, and also affecting the preliminary mixing of the liquid drops in the biogas.

[0041] (4) When the output of biogas is low, the present application blocks part of the biogas, so that the biogas will gather in the separation tank, which will increase the local biogas concentration, so that the ultrasonic generator has more biogas nearby, and the reciprocating assembly speeds up the flow rate of biogas in the arc-shaped groove, so that the liquid drops are more easily mixed, effectively preventing the biogas drops from being more dispersed and difficult to mix when the biogas content is low, affecting the sedimentation of the liquid drops and affecting the separation of the liquid drops in the biogas; in addition, the inclined baffle blocks the biogas at the outlet position of the arc-shaped groove, and at the same time, the liquid drops fall into the collection frame, effectively preventing the two biogas from colliding and being more turbulent, and the condensed liquid drops are scattered again by the turbulent gas flow when the liquid drops fall in this position.

DETAILED DESCRIPTION

[0055] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0056] For example 1, please refer to Figures 1-4 The present invention is a gas separation device based on ultrasonic resonance, comprising 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 penetratingly connected to the inner wall of the separation tank 111;

[0057] Separation mechanism 1, a condensation assembly 11 is fixedly provided on the inner wall of the separation mechanism 1, and a driving assembly 12 is installed on the top of the separation mechanism 1. The condensation assembly 11 is used to separate the liquid droplets in the biogas;

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

[0059] The expansion mechanism 3 is located at the inner wall of the separation mechanism 1 to accelerate the collision speed of the biogas;

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

[0061] Among them, biogas is injected into the separation tank 111 through the air inlet pipe 112, and then the droplets in the biogas are mixed through the separation mechanism 1 to allow the droplets to settle, and then the flow speed 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, so that the droplets can gather into larger droplets, making it easier for the droplets to settle, thereby promoting the separation of the droplets in the biogas from the biogas, effectively preventing the biogas flow from being too fast, and the high-speed airflow easily carrying larger droplets to flow, so that the biogas and the droplets are fully separated.

[0062] The separation mechanism 1 comprises:

[0063] The condensation component 11 is fixedly arranged at the outer wall of the condensation component 11 and the inner wall of the separation tank 111, and is used to mix the liquid droplets in the biogas;

[0064] A driving assembly 12, the bottom of which is fixedly arranged on 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, the biogas is injected into the separation tank 111 through the air inlet pipe 112, and then the vibrator in the condensation component 11 vibrates and mixes the liquid droplets in the biogas, thereby promoting the sedimentation of the liquid droplets.

[0066] Mitigation mechanism 2 includes:

[0067] The flow guide component 21 is fixedly arranged on the side wall of the gas storage frame 114 and is used to guide the flow of biogas;

[0068] The blocking component 22 is rotatably disposed on the inner wall of the gas storage frame 114 and is used to guide the discharge of biogas;

[0069] Among them, when the biogas enters the separation tank 111, the biogas flow is guided by the guide component 21, and the biogas is separated into two streams, which are made to collide with each other, consume the kinetic energy of the biogas, slow down the flow speed of the biogas, and reduce the drag on the droplets in the biogas. Afterwards, the flow of biogas is blocked multiple times by the blocking component 22, giving the droplets in the biogas time to fully mix, so that the droplets can gather into larger droplets, making it easier for the droplets to settle.

[0070] Expansion mechanism 3 includes:

[0071] The discharge component 31 is fixedly arranged on the inner wall of the gas storage frame 114 and is used to discharge the mixed liquid droplets;

[0072] The reciprocating assembly 32 is slidably disposed on the inner wall of the separation tank 111 through a sliding member, and is used to squeeze the biogas and accelerate the collision speed of the biogas;

[0073] The sliding member includes a spring ring 321 slidably connected to the inner wall of the separation tank 111, and a fixing frame 322 is fixedly connected to the inner wall of the separation tank 111;

[0074] Among them, after the droplets are mixed and settled, the settled droplets are discharged through the discharge component 31, and then rise through the reciprocating component 32 to squeeze the biogas and accelerate the collision speed of the biogas, effectively preventing the biogas from having small droplets and taking a long time to mix. Since the biogas will continue to be injected into the separation tank 111, the blocking component 22 blocks the biogas for too long, which may easily cause the pressure in the separation tank 111 to be too high. The blocking time of the blocking component 22 is relatively short, which may easily cause the droplets to be difficult to fully mix.

[0075] For 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 connected to 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 the biogas into the separation tank 111 through the air inlet pipe 112 , and the biogas is accumulated in the separation tank 111 until a large amount of biogas is accumulated.

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

[0078] The flow guide assembly 21 includes two inclined panels 214 slidably connected to the inner wall of the collection frame 213. The left and right sides of the gas storage frame 114 are fixedly connected to L-shaped blocks 215. The inner walls of the two L-shaped blocks 215 are each provided with an extension groove 216.

[0079] The biogas will enter the extension groove 216 and the arc groove 211, allowing the biogas to flow in the two arc grooves 211 and be divided into two streams. The two streams of biogas will collide at the outlet of the arc groove 211, consuming the kinetic energy of the biogas and slowing down the flow speed of the biogas. The biogas will then enter the gas storage frame 114 and be concentrated in the gas storage frame 114. Since a higher temperature is required for the generation of biogas, the heat of the biogas is higher, resulting in a lower gas density and a flow upward.

[0080] The blocking assembly 22 includes a fan-shaped frame 221 provided 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 the biogas enters the gas storage frame 114, the motor 121 is started to drive the rotating rod 122 to rotate, thereby causing the fan-shaped frame 221 to rotate slowly. During the rotation process of the fan-shaped frame 221, when the protruding position of the fan-shaped frame 221 contacts the push rod 223, the push rod 223 will be squeezed down.

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

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

[0084] Among them, the collecting frame 213 and the spring bevel ring 313 are driven to descend, allowing the spring bevel ring 313 to accumulate rebound force, allowing the collecting frame 213 to separate from the bevel baffle 212, eliminating the obstruction to the biogas, and the biogas will flow to the position of the ultrasonic generator 115. After that, the ultrasonic generator 115 is started to generate ultrasonic resonance, and the vibration drives the surrounding biogas and droplets to form local vortices, and the droplets scattered in different areas are drawn into the vortex center to achieve mixing of droplets between areas. As the fan-shaped frame 221 continues to rotate, the fan-shaped frame 221 will cover the fan-shaped groove 222 to prevent the biogas from rising. At the same time, the concave position of the fan-shaped frame 221 will contact the push rod 223 again, and the squeezing force on it disappears. At this time, the spring The rebound force of the spring bevel ring 313 is released, allowing the push rod 223 and the collection frame 213 to return to their original positions, allowing the collection frame 213 to fit with the bevel baffle 212, thereby blocking the biogas from flowing to the position of the ultrasonic generator 115, giving time for the liquid droplets in the biogas to mix. By slowing down the flow of the biogas, the biogas is concentrated in one place, making the density of the tiny droplets higher, and the energy of the ultrasonic vibration can act more concentratedly on the droplets. In combination with blocking the flow of biogas, time is given for the droplets to fully mix, allowing the droplets to gather into larger droplets, making it easier for the droplets to settle, and promoting the separation of the liquid droplets in the biogas from the biogas, effectively preventing the biogas from flowing at a high flow rate, which is likely to carry larger droplets, and thus fully separating the biogas from the droplets.

[0085] With the continuous rotation of the sector frame 221, the sector frame 221 will cancel the blocking of the sector groove 222, and the biogas will flow upward through the sector groove 222 into the gas outlet pipe 113, and the biogas will be discharged through the gas outlet pipe 113. At the same time, the protruding position of the sector frame 221 will again extrude the push rod 223 and make the collection frame 213 descend, so that the untreated biogas moves to the position of the ultrasonic generator 115. Such reciprocating movement separates the liquid droplets in the biogas, and the mixed liquid droplets fall into the collection frame 213 and accumulate in the collection frame 213. When the collection frame 213 descends, the collection frame 213 will be separated from the inclined plate 214. At this time, the liquid droplets will slide down the inclined surface of the two to the hopper frame 311, and then enter the liquid discharge pipe 312 through the hopper frame 311. Since the push rod 223 pushes the collection frame 213 to descend, the spring inclined ring 313 will also descend and be separated from the inclined surface of the liquid discharge pipe 312, thereby canceling the blocking of the liquid droplets. The liquid droplets will be discharged through the liquid discharge pipe 312.

[0086] The reciprocating assembly 32 comprises a rocker plate 323 rotationally connected to the outer wall of the fixed frame 322, and the inner wall of the gas storage frame 114 is slidably connected with an extrusion rod 324, and the top of the extrusion rod 324 is fixedly connected with the bottom of the collection frame 213.

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

[0088] When the collection frame 213 descends, the extrusion rod 324 will descend, and the extrusion rod 324 will push the rocker plate 323 to rotate, so that the side of the rocker plate 323 in contact with the extrusion rod 324 descends and the other side rises. The rising side will push the spring ring 321 to rise, so that the spring ring 321 accumulates the elastic force and extrudes the biogas in the separation tank 111 to flow, thereby accelerating the flow speed of the biogas and pushing the biogas to enter the arc-shaped groove 211 at a faster speed, thereby enhancing the collision effect. When the liquid droplets collide at a high speed, the relative kinetic energy of the liquid droplets is significantly increased, which is sufficient to break through the limitation of the surface repulsive force of the liquid droplets and promote the mixing of part of the liquid droplets when the biogas collides. Thus, the larger liquid droplets can more easily mix with the smaller liquid droplets, the mixing speed of the subsequent liquid droplets is accelerated, and the liquid droplets in the biogas are effectively prevented from being too small and taking too long to mix. Since the biogas will continue to be injected into the separation tank 111, the sector frame 221 will block the biogas for too long, which is easy to cause the pressure in the separation tank 111 to be too high, and the sector frame 221 will block the biogas for too short, which is easy to cause the liquid droplets to be difficult to fully mix.

[0089] The number of the above-mentioned assemblies is not limited, and those skilled in the art can freely set according to actual needs, as long as the above-mentioned assemblies are installed at the corresponding assembly connection positions.

[0090] A specific application of this embodiment is: when the present invention is used, the operator sends the biogas into the separation tank 111 through the air inlet pipe 112, and the biogas will gather in the separation tank 111 until more biogas is gathered. The biogas will enter the extension groove 216 and the arc groove 211, allowing the biogas to flow in the two arc grooves 211, and the biogas will be divided into two streams. The two streams of biogas will collide at the outlet position of the arc groove 211, consuming the kinetic energy of the biogas and slowing down the flow speed of the biogas. The biogas will then enter the gas storage frame 114, so that the biogas is concentrated in the gas storage frame 114. Since biogas needs to be generated when it is generated, The heat of the biogas is high, which reduces the gas density and causes it to flow upward. When the biogas enters the gas storage frame 114, the motor 121 is started to drive the rotating rod 122 to rotate, thereby causing the fan-shaped frame 221 to rotate slowly. During the rotation process of the fan-shaped frame 221, when the protruding portion of the fan-shaped frame 221 contacts the push rod 223, the push rod 223 is squeezed downward, driving the collection frame 213 and the spring bevel ring 313 to descend, allowing the spring bevel ring 313 to accumulate rebound force, allowing the collection frame 213 to separate from the bevel baffle 212, thereby eliminating the obstruction to the biogas.

[0091] The biogas will flow to the position of the ultrasonic generator 115, and then the ultrasonic generator 115 will be started to generate ultrasonic resonance. The vibration drives the surrounding biogas and droplets to form a local vortex, and the droplets scattered in different areas are drawn into the vortex center to achieve mixing of droplets between areas. As the fan-shaped frame 221 continues to rotate, the fan-shaped frame 221 will cover the fan-shaped groove 222 to prevent the biogas from rising. At the same time, the concave position of the fan-shaped frame 221 will contact the push rod 223 again, and the squeezing force on it will disappear. At this time, the rebound force of the spring bevel ring 313 will be released, allowing the push rod 223 and the collection frame 213 to return to their original positions. The collecting frame 213 is fitted with the inclined baffle 212 to block the biogas from flowing to the ultrasonic generator 115, giving the liquid droplets in the biogas time to mix. By slowing down the flow of the biogas, the biogas is concentrated in one place, making the density of the tiny droplets higher. The energy of the ultrasonic vibration can act more concentratedly on the droplets. In combination with blocking the flow of biogas, the droplets are given time to fully mix, allowing the droplets to gather into larger droplets, making it easier for the droplets to settle, and promoting the separation of the liquid droplets in the biogas from the biogas. This effectively prevents the high-speed biogas flow, which easily carries larger droplets, and fully separates the biogas from the droplets.

[0092] Among them, as the fan-shaped frame 221 continues to rotate, the fan-shaped frame 221 will remove the obstruction of the fan-shaped groove 222, and the biogas will flow upward through the fan-shaped groove 222 and enter the outlet pipe 113, and the biogas will be discharged through the outlet pipe 113. At the same time, the protruding position of the fan-shaped frame 221 will squeeze the push rod 223 and the collection frame 213 to move downward, so that the untreated biogas moves to the position of the ultrasonic generator 115, and so on. The liquid droplets in the biogas are separated, and the mixed liquid droplets will fall. The liquid droplets gather in the collection frame 213. When the collection frame 213 descends, the collection frame 213 separates from the inclined plate 214. At this time, the liquid droplets slide along the inclined surfaces of the two and fall into the funnel frame 311. Then, they pass through the funnel frame 311 and enter the drainage pipe 312. When the push rod 223 pushes the collection frame 213 downward, the spring inclined ring 313 also descends and separates from the inclined surface of the drainage pipe 312, eliminating the obstruction to the liquid droplets. The liquid droplets are then discharged through the drainage pipe 312.

[0093] Secondly, when the collecting frame 213 descends, the squeezing rod 324 will be driven to descend, and the squeezing rod 324 will push the seesaw 323 to rotate, so that the side of the seesaw 323 in contact with the squeezing rod 324 will descend and the other side will rise. The rising side will push the spring ring 321 to rise, so that the spring ring 321 accumulates the rebound force, and the spring ring 321 will squeeze the biogas flow in the separation tank 111, accelerate the flow speed of the biogas, and push the biogas into the arc groove 211 at a faster speed, thereby enhancing the collision effect. When the collision is accelerated, the relative The kinetic energy is significantly increased, enough to break through the limitation of the repulsive force on the surface of the droplets, and can promote the mixing of some droplets when the biogas collides, so that during the subsequent ultrasonic vibration, larger droplets can more easily mix with smaller droplets, speeding up the mixing speed of subsequent droplets, and effectively preventing the small droplets in the biogas from taking a long time to mix. Since the biogas will be continuously injected into the separation tank 111, the fan-shaped frame 221 will block the biogas for too long, which may easily cause the pressure in the separation tank 111 to be too high. The fan-shaped frame 221 has a short blocking time, which may easily cause the droplets to be difficult to fully mix.

[0094] Secondly, the biogas is guided into the arc-shaped groove 211 at the bottom through the extension groove 216 in the L-shaped block 215, so that the opening height of the extension groove 216 and the opening height of the top arc-shaped groove 211 are at the same height, and the size of the extension groove 216 is larger than the size of the arc-shaped groove 211, which reduces the intake resistance, allowing the gas to flow more easily into the bottom arc-shaped groove 211, guiding the entry of the biogas, and making the amount of biogas entering the two arc-shaped grooves 211 tend to be uniform, effectively preventing the biogas from having a certain temperature and gathering upward in the separation tank 111, which easily causes the biogas content at the top of the separation tank 111 to be higher and lower 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, making it difficult for the two airflows to effectively offset each other, affecting the deceleration of the gas and, at the same time, affecting the initial mixing of liquid droplets in the biogas.

[0095] Secondly, by blocking part of the biogas, the droplets in this part of the biogas are separated, so that the biogas will gather in the separation tank 111 and the pressure will increase. When the output of biogas is low, the biogas gathers in the separation tank 111, which will increase the local biogas concentration, so that there is more biogas near the ultrasonic generator 115, and the reciprocating component 32 is used to accelerate the flow speed of biogas in the arc groove 211, so that the local concentration of biogas increases, and the droplets are easier to mix, which effectively prevents the biogas droplets from being more dispersed and difficult to mix when the biogas content is low, affecting the sedimentation of the droplets and affecting the separation of the droplets in the biogas. In addition: the biogas at the outlet of the arc groove 211 is blocked by the inclined baffle 212, and at the same time, the droplets fall into the collection frame 213, which effectively prevents the two biogases from being more turbulent after collision. When the droplets fall at this position, it is easy to cause the condensed droplets to be dispersed again by the turbulent airflow.
