Description

Technical Field

[0001] This invention relates to the field of gas-liquid separation technology, specifically to a multi-stage high-efficiency gas-liquid separator and its separation method. Background Technology

[0002] Gas-liquid separation technology is a key process in chemical, petroleum, energy, and environmental protection fields. Its core function is to effectively separate the gaseous and liquid components in a gas-liquid mixture to meet the requirements of subsequent processes for gas purity or liquid recovery. With the increasing sophistication of industrial production, the demands for gas-liquid separation efficiency, precision, and equipment adaptability are rising, especially in scenarios with significant fluctuations in liquid content (such as chemical reaction tail gas treatment, associated gas separation from natural gas extraction, and steam condensation recovery). Highly efficient and stable separation equipment has become crucial for improving production efficiency and reducing energy consumption.

[0003] A major problem with existing multi-stage gas-liquid separators is their inability to achieve adaptive adjustment. In traditional multi-stage gas-liquid separators, the operating parameters of each separation stage, such as the rotational speed during centrifugation and the working state of the separation elements, are mostly preset fixed values. During actual operation, when the initial liquid content of the gas-liquid mixture changes, the equipment cannot automatically adjust the operating parameters of each separation stage accordingly. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a multi-stage high-efficiency gas-liquid separator and its separation method.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a multi-stage high-efficiency gas-liquid separator and its separation method, comprising: A separation cylinder, the top end of which is fixedly connected to a connecting pipe, the other end of which is fixedly connected to a processing cylinder, and the other outer wall of the processing cylinder is fixedly connected to an air inlet pipe.

An upper toothed plate is fixedly connected to the outer wall of the first connecting ring, and the outer wall of the upper toothed plate is in rotatable contact with the inner wall of the separation cylinder.

[0010] Preferably, a rotating cylinder is rotatably connected to the outer wall of the rotating rod, a second impact plate is fixedly connected to the outer wall of the rotating cylinder, a second connecting ring is fixedly connected to the other end of the second impact plate, the second impact plate is tilted left and right between the rotating cylinder and the second connecting ring, the second impact plate is tilted up and down between the rotating cylinder and the second connecting ring, and the tilting direction of the second impact plate is from the second connecting ring to the rotating cylinder. A lower toothed plate is fixedly connected to the outer wall of the second connecting ring, the outer wall of the lower toothed plate is rotatably in contact with the inner wall of the separation cylinder, a rotating shaft is rotatably connected to the inner wall of the separation cylinder, a gear is fixedly connected to the outer wall of the rotating shaft, and both the upper toothed plate and the lower toothed plate mesh with the gear.

[0011] Preferably, the inner wall of the separation cylinder is provided with a fixing groove, and the inner wall of the fixing groove is fixedly connected to a plurality of first drain pipes. The first drain pipes extend obliquely to the outer wall of the separation cylinder. The outer wall of the rotating rod is rotatably connected to a collection shell. The bottom end of the collection shell is fixedly connected to a plurality of second drain pipes. The other end of the second drain pipes extends to the outside of the separation cylinder. The inner wall of the separation cylinder is provided with a collection groove, and the collection groove is located at the inclined end of the hydrophobic membrane. The inner wall of the collection groove is fixedly connected to a third drain pipe, and the other end of the third drain pipe extends to the outside of the separation cylinder. A float-type one-way drain valve is provided in the first drain pipe, the second drain pipe, and the third drain pipe.

[0012] Preferably, the outer wall of the separation cylinder is fixedly connected with a plurality of support legs arranged in a circular array, the bottom end of the separation cylinder is embedded with an exhaust fan, the output end of the exhaust fan is fixedly connected to an air outlet pipe, the other end of the air outlet pipe is fixedly connected to a liquid content detector, and the liquid content detector is electrically connected to the PLC controller to form a third detection loop.

[0013] Preferably, a separation method for a multi-stage high-efficiency gas-liquid separator includes the following steps: S1. The gas-liquid mixture is fed into the processing cylinder through the air inlet pipe for primary separation; S2. After the primary separation is completed, the gas-liquid mixture enters the separation cylinder, and the gas-liquid mixture undergoes secondary separation by rotating the rotating rod. S3. Then, the gas and liquid are further separated in a secondary process by the rotation of the first and second impact plates. S4. After the secondary separation process, a tertiary separation process is carried out through a hydrophobic membrane.

[0014] The technical solution provided by this invention has the following advantages compared with the known prior art: This multi-stage high-efficiency gas-liquid separator, through the installation of detection structures such as an infrared emitting plate, an infrared receiving plate, and a liquid level detection rod, combined with a PLC controller, can monitor the initial gas-liquid content and the amount of liquid separated in the first stage in real time. When the separation effect is detected to be poor, the PLC controller will automatically adjust the power of the drive motor in the second-stage processing component and change the rotation speed of the rotor, thereby adaptively adjusting the separation force to meet the separation requirements of gas-liquid mixtures with different liquid contents.

[0015] This separator employs a three-stage separation mechanism. The first stage separates gas and liquid due to inertial differences via baffles, with liquid particles condensing and dripping after impacting the baffles. The second stage utilizes centrifugal force generated by the rotation of the rotor, along with the high-speed counter-rotating alternating rotation of the first and second impact plates, to further break down and condense liquid particles. The third stage intercepts tiny droplets through a hydrophobic membrane. This three-stage separation process is progressive and more efficient than the single or limited separation methods of traditional separators, enabling the separation of gas-liquid mixtures.

[0016] On the one hand, during the secondary separation process, the multi-stage high-efficiency gas-liquid separator increases the impact frequency and force of the gas-liquid mixture through the high-speed counter-rotation of the first and second impact plates. This effectively breaks down and agglomerates liquid particles that were not completely separated in the first stage, while generating a stronger centrifugal effect, causing more liquid particles to be thrown against the inner wall of the separation cylinder or the outer wall of the fixed cylinder for discharge. On the other hand, the liquid content of the discharged gas is detected in real time by a liquid content detector at the end of the air outlet pipe. If the liquid content does not meet the standard, the PLC controller will continue to adjust the power of the secondary processing components until the liquid content meets the requirements, thus ensuring the separation effect.

[0029] The outer wall of the separation cylinder 1 is fixedly connected with multiple support legs 6 arranged in a circular array. The bottom end of the separation cylinder 1 is embedded with an exhaust fan 7. The output end of the exhaust fan 7 is fixedly connected to an air outlet pipe 8. The other end of the air outlet pipe 8 is fixedly connected to a liquid content detector 9. The liquid content detector 9 is electrically connected to the PLC controller to form a third detection circuit.

[0030] The working principle of this invention is as follows: When the gas-liquid mixture enters the processing cylinder 3 through the inlet pipe 4, it will first undergo primary separation; First, after the gas and liquid enter the inlet pipe 4, the infrared emitting plate 5122 and the infrared receiving plate 5123 in the inlet pipe 4 form the first detection circuit. By measuring the change in infrared transmittance, the PLC controller detects the initial liquid content of the gas and liquid in real time. When infrared light passes through the gas-liquid mixture in the inlet pipe 4, the liquid particles in the mixture will absorb, reflect, and scatter the infrared light. The higher the liquid content, the more numerous and densely distributed the liquid particles in the gas and liquid, and the more significant the degree of blocking and attenuation of infrared light during propagation, resulting in a decrease in the transmittance reaching the infrared receiving plate 5123. The PLC controller acquires the transmittance data received by the infrared receiver board 5123 in real time. Combined with the preset calibration curve (which is established in advance through experiments to reflect the correspondence between different liquid contents and infrared transmittance), it can quickly calculate the liquid content of the initial gas-liquid mixture. This detection method can achieve non-contact real-time monitoring, avoid interference with gas-liquid flow, and has the characteristics of fast response speed and high detection accuracy. It provides accurate initial parameter basis for the power adjustment of the drive motor 521 in the subsequent secondary separation, ensuring that the separation process is dynamically adapted according to the initial state of gas and liquid, and improving the overall separation efficiency.

[0031] After the mixture enters the processing cylinder 3, it is blocked by multiple staggered array baffles 511. During the baffle process, the gas and liquid flow separate due to inertial differences. Liquid particles collide with the baffles 511 and then condense and drip down, flowing into the collection box 513 through the connecting port. The liquid level detection rod 5124 in the collection box 513 forms a second detection circuit, which monitors the amount of liquid separated in the first stage in real time (the solenoid valve will automatically open at fixed intervals; if the liquid level detected by the liquid level detection rod 5124 drops suddenly during this period but the detected liquid content does not decrease, the gas-liquid separation effect during this period is poor, and the separation power needs to be increased in the second separation stage). After the solenoid valve opens, the separated liquid is discharged into the collection tank 516 through the drain pipe 515, completing the collection and control of the liquid volume separated in the first stage.

[0032] When the liquid level detected by the level sensor 5124 suddenly drops but the liquid content does not decrease, the PLC controller determines that the gas-liquid separation effect is poor during this period and immediately sends a signal to increase the power of the drive motor 521 of the secondary processing component 52. Since the drive motor 521 and the PLC controller are connected by an electrical signal to form an adjustment loop, the output power of the drive motor 521 increases at this time, driving the rotating rod 522 to rotate at a higher speed. After the rotation speed of the rotating rod 522 increases, the stirring force of the agitator 523 on its outer wall on the gas-liquid mixture entering the separation cylinder 1 is enhanced, making the gas-liquid mixture subject to greater centrifugal force, which is more conducive to the liquid particles being thrown towards the inner wall of the separation cylinder 1, thus improving the initial effect of secondary separation. The liquid adhering to the inner wall of the separation cylinder 1 flows into the fixed tank 5214 and is discharged through the inclined first drain pipe 5215 (with a built-in float-type one-way drain valve to prevent gas leakage).

[0033] At the same time, the rotating rod 522 drives the fixed cylinder 524 and the first impact plate 525 to rotate faster. Through the transmission of the upper toothed plate 527, the gear 5213 and the lower toothed plate 5211, the reverse rotation speed of the second impact plate 529 also increases synchronously. The high-speed, counter-rotating alternating rotation of the first impact plate 525 and the second impact plate 529 increases the frequency and force of the impact with the gas-liquid mixture, which can more effectively break and agglomerate liquid particles that have not been completely separated in the first stage. It can also cause some liquid droplets to adhere to the first impact plate 525 and the second impact plate 529. Since the first impact plate 525 and the second impact plate 529 are tilted, the liquid droplets can gather near the fixed cylinder 524 and flow into the collection shell 514, and be discharged through the second drain pipe 5216. On the other hand, the higher rotation speed generates a stronger centrifugal effect, causing more liquid particles to be thrown towards the inner wall of the separation cylinder 1 or the outer wall of the fixed cylinder 524, and then discharged through the first drain pipe 5215 and the second drain pipe 5216. After the increased power processing in the secondary separation stage, the liquid particles in the gas-liquid mixture are further reduced. Subsequently, the gas-liquid mixture moves upward and comes into contact with the hydrophobic membrane 531 inclined inside the separation cylinder 1, entering the tertiary separation stage. The hydrophobic membrane 531 uses its hydrophobic properties to intercept the tiny droplets remaining in the gas. Due to the inclined arrangement of the hydrophobic membrane 531, the intercepted droplets slide down along the inclined direction under the action of gravity into the collection tank 5218, and are finally discharged through the third drain pipe 5217.

[0034] The separated gas is discharged through the exhaust pipe 8 under the action of the exhaust fan 7. The liquid content detector 9 at the end of the exhaust pipe 8 detects the liquid content of the gas and transmits the data to the PLC controller. If the liquid content meets the standard, the equipment maintains its current operating state; if it still does not meet the standard, the PLC controller will continue to adjust the power of the secondary processing component 52 until the liquid content meets the requirements, ensuring that the entire gas-liquid separation process is efficient and thorough.

[0035] The entire process involves a three-stage separation process (baffle interception → centrifugal impact → hydrophobic membrane 531 filtration), combined with real-time detection and intelligent adjustment, to achieve efficient and precise separation of gas-liquid mixtures.

[0036] A separation method for a multi-stage high-efficiency gas-liquid separator includes the following steps: S1. The gas-liquid mixture is fed into the processing cylinder 3 through the air inlet pipe 4 for primary separation; S2. After the primary separation is completed, the gas-liquid mixture enters the separation cylinder 1, and the gas-liquid mixture is further separated by rotating the rotating rod 522. S3. Then, the gas and liquid are further separated by the rotation of the first impact plate 525 and the second impact plate 529. S4. After the secondary separation process, a tertiary separation process is carried out through the hydrophobic membrane 531.
