Description

Technical Field

[0001] This invention belongs to the field of gas-liquid separation technology, specifically relating to a sound-assisted vertical gas-liquid separation device with sound frequency control. Background Technology

[0002] In industrial production (such as oil extraction, chemical reactions, gas purification, etc.), the efficient separation of gas-liquid mixtures is one of the core links to ensure product quality, equipment safety and process efficiency.

[0003] In gas-liquid separation processes, wire mesh demisters are often used as the final separation unit. They rely on the interception and inertial collision of the wire mesh to capture tiny droplets in the gas phase, making them a core component for achieving fine separation. However, this equipment faces key technical bottlenecks in actual operation: when the gas phase carries droplets through the wire mesh, the droplets will accumulate on the wire mesh surface to form a continuous liquid film. As the thickness of the liquid film increases, the high-speed airflow can easily tear the liquid film into new tiny droplets, which will flow out with the gas phase, directly causing secondary entrainment problems and significantly reducing separation efficiency. At the same time, the accumulation of the liquid film can also clog the wire mesh pores, leading to increased gas phase flow resistance, increased equipment energy consumption, and decreased operational stability.

[0004] To alleviate the liquid film problem, existing methods mostly focus on optimizing the wire mesh structure or adding a rinsing system. However, structural optimization can only delay the formation of the liquid film and cannot fundamentally eliminate the liquid film that has already been formed. The rinsing system requires the introduction of an additional medium, which increases the complexity of the process and the operating cost, and is not suitable for working conditions that require water resistance or high purity.

[0005] The acoustic vibration effect of acoustic technology can disrupt the stability of the fluid interface through periodic mechanical vibration. Theoretically, it can be used to break the continuous liquid film on the surface of the wire mesh. However, in the existing technology, acoustic means are only used alone for droplet aggregation and have not been combined with wire mesh demisters to form a synergistic separation system of "wire mesh + sound wave". At the same time, there is a lack of sound frequency and sound intensity control schemes for industrial-grade wire mesh demister scenarios, making it difficult to adapt to the working conditions with different liquid film thicknesses and fluid characteristics.

[0006] Therefore, the industry urgently needs a gas-liquid separation device that can accurately break the liquid film on the surface of the wire mesh, avoid secondary entrainment, and be suitable for high-flow industrial conditions, in order to solve the liquid film bottleneck of traditional wire mesh demisters and improve separation efficiency and equipment stability.

Detailed Implementation

[0020] The invention will be further described with reference to the accompanying drawings.

[0021] As shown in the figure, a sound-assisted vertical gas-liquid separator with sound frequency control includes a vertical separator tank 1. A saddle 2 is provided at the bottom of the vertical separator tank for support. An inlet 3 is opened on the side of the tank body, and an adjustable baffle 4 is correspondingly provided at the inlet to buffer and guide the flow of the gas-liquid mixture entering the tank. A wire mesh demister 5 is installed in the upper part of the vertical separator tank 1 to capture tiny droplets in the gas phase. An electromagnetically driven sound wave generator 7 is installed on the top of the vertical separator tank 1 via a support frame 6. The output of the sound wave generator is transmitted through a conductive... Rod 8 is connected to a conical acoustic diffuser 9 and a cylindrical acoustic diffuser 10. The conical acoustic diffuser 9 is positioned above the wire mesh demister 5 and contains a flow guide groove. The cylindrical acoustic diffuser 10 is placed inside the wire mesh demister and contains uniform small holes to achieve comprehensive and uniform coverage of sound waves in the wire mesh demister area. A differential pressure transmitter 11 is installed on the side of the vertical separation tank 1 to monitor the flow resistance in the wire mesh demister area in real time. A gas phase outlet 12 is opened at the top of the tank, and a liquid phase outlet 13 is opened at the bottom of the tank to discharge the separated gas phase and liquid phase media, respectively.

[0022] The adjustable baffle 4 comprises a main shaft 41 and a secondary shaft 42. One end of the main shaft 41 is connected to a handle 411 and a tray 412, while the other end houses a three-stage gear within a gearbox 43. A linear guide rail 413 is internally located within the main shaft 41 and connected to a spring plate 416 via a combination of a washer 414, a spring 415, and another washer 414. The spring plate 416 integrates a buckle 417 and an adjustment button 418. One end of the secondary shaft 42 has a three-stage gear, also housed within the gearbox 43, meshing with the three-stage gear on the main shaft 41 in a staggered manner. The other end features a worm gear structure that meshes with a worm wheel 44 to form a worm-worm transmission mechanism. A semi-enclosed outer shell 45 protects the worm wheel 44 from impact and wear.

[0023] The wire mesh demister 5 includes a support ring 51, and a limiting cylinder 52 is fastened to the support ring 51 by bolts. A wire mesh 53 is provided inside the limiting cylinder 52. This wire mesh 53 consists of three layers of wire mesh with different apertures, and each layer of wire mesh is isolated and positioned by a support plate 54. A pressure ring 55 is provided on the uppermost layer of the wire mesh assembly 53, and a pressure plate 56 is mounted on the pressure ring 55. A metal hoop 57 is fitted around the outside of the limiting cylinder 52 to axially compress and fix the limiting cylinder 52.

[0024] The electromagnetically driven acoustic wave generator 7 includes a magnetically shielded shell 71, an electromagnetic component 72, a transmission component 73, and a rigid diaphragm 74.

[0025] The electromagnetic component 72 includes a permanent magnet 721, to which a sliding rod 722 is connected, and an electromagnet component 723 is placed on the sliding rod 722 via a linear bearing.

[0026] The electromagnet assembly 723 includes an electromagnet 7231, with electromagnet bases 7232 mounted at both ends. A copper heat-conducting cylinder 7233 is bonded and fixed around the electromagnet 7231 with thermally conductive silicone grease, transferring heat through the electromagnet bases 7232 to heat transfer plates 7234 on the left and right sides, with the heat transfer plates 7234 on the upper and lower sides arranged in a staggered pattern. Fin-shaped heat sinks 7235 are evenly distributed on each heat transfer plate 7234, forming a highly efficient heat dissipation structure. A wire is wound around the outer periphery of the electromagnet 7231, leading to three connection ports 7236, which are electrically connected to an AC power supply 7237 and an adjustment switch 7238, respectively. A cable chain 7239 is also provided on the wire for protection and guidance.

[0027] The transmission assembly 73 includes a connecting rod 731, one end of which is connected to the electromagnet base 7232, and the other end is connected to a transmission rod 732. The transmission rod 732 has a guide groove 733 and is fastened to the magnetic shielding shell 71 by bolts. A support plate is welded to the lower end of the transmission rod 732, and three ear plates 734 are provided on the support plate. One end of the tapered frame 735 is connected to the support plate via the ear plates 734, and the other end is also connected to an elastic pin coupling 736 on the rigid diaphragm 74 via the ear plates 734. The rigid diaphragm 74 is fixed to the magnetic shielding shell 71 by an elastic ring to achieve stable assembly.

[0028] When the gas-liquid separation device of the present invention is working, the gas-liquid mixture enters the vertical separation tank 1 through the feed inlet 3. The adjustable baffle 4 can be adaptively adjusted according to the different gas-liquid ratios of the feed: when the gas phase ratio is high, the angle between the baffle and the airflow direction is reduced to reduce local eddies and impacts, thereby reducing the gas phase flow resistance and improving the gas phase discharge efficiency; when the liquid phase ratio is high, the angle between the baffle and the airflow direction is increased to prolong the residence time of the gas phase in the device, while more effectively blocking and guiding the liquid phase, promoting the liquid phase to aggregate and slide down, and improving the gas-liquid separation efficiency.

[0029] The adjustment operation of the adjustable baffle 4 is as follows: By rotating the handle 411 on the rotating tray 412, the main shaft 41 is driven to rotate, and the gears in the gearbox 43 mesh with each other, thereby driving the auxiliary shaft 42 to rotate. The worm gear structure at the end of the auxiliary shaft 42 synchronously drives the turbine 44 to rotate. Utilizing the self-locking characteristic of the worm gear structure, it can effectively prevent the turbine from generating a reaction force on the worm due to excessive feed or excessive speed. When it is necessary to speed up or slow down the rotation speed for precise control, the adjustment button 418 can be pressed. The spring plate 416 will move down accordingly, and the equally spaced buckles 417 distributed on it will also retract into the main shaft 41. At this time, push the main shaft 41 towards the gearbox 43, and the shim 414 will slide along the linear guide rail 413, so that the buckle 417 coincides with the next slot, and the secondary gear in the gearbox 43 also meshes. After releasing the adjustment button 418, the speed adjustment of the adjustable baffle 4 can be completed, and the baffle angle can be precisely controlled.

[0030] When gas carrying liquid enters the tank, the liquid settles to the bottom of the tank under gravity, while the gas flows upward. The gas accumulated in the upper part of the tank moves downward along the guide groove on the conical acoustic diffuser 9 and is eventually discharged from the gas phase outlet 12. During the upward flow of gas, a liquid film may form on the wire mesh 53 of the wire mesh demister 5. This will cause a change in the differential pressure on both sides of the wire mesh demister 5. The differential pressure transmitter 11 will capture this differential pressure signal in real time and transmit it to the electromagnetically driven acoustic generator 7 to trigger the acoustic demister action.

[0031] The working process of the electromagnetically driven acoustic wave generator 7 is as follows: The AC power supply 7237 generates alternating current with periodically changing direction, causing the electromagnet 7231 to generate a periodic alternating magnetic field. Under the magnetic field of the permanent magnet 721, the electromagnet 7231 reciprocates up and down along the sliding rod 722, driving the electromagnet base 7232 and connecting rod 731 mounted thereon to move synchronously, thereby driving the transmission rod 732 to slide back and forth within the guide groove 733. Since the end of the transmission rod 732 is securely connected to the rigid diaphragm 74 via the conical frame 735, the rigid diaphragm 74 vibrates and emits sound waves with the reciprocating motion of the transmission rod 732. Simultaneously, based on the magnitude of the differential pressure signal transmitted by the differential pressure transmitter 11, the current intensity input to the electromagnet 7231 can be changed by adjusting the regulating switch 7238, causing it to generate alternating magnetic fields of different intensities, thereby changing the reciprocating range of the sliding rod 722, ultimately achieving multi-level adjustment of the acoustic wave frequency to adapt to different liquid film thickness conditions.

[0032] Meanwhile, a copper heat-conducting cylinder 7233 is provided around the electromagnet 7231, which can absorb the heat generated by its up-and-down movement and conduct the heat to the heat transfer plate 7234 on the electromagnet base 7232, and then dissipate the heat through the finned heat dissipation plate.

[0033] The sound waves generated by the rigid diaphragm 7 are transmitted to the conical sound wave diffuser 9 and the cylindrical sound wave diffuser 10 through the transmission rod 8. The sound waves are reflected by the conical sound wave diffuser to generate uniform downward sound waves. At the same time, the cylindrical sound wave diffuser 10 with small holes will also disperse the sound waves evenly in all directions. The two work together to break the liquid film attached to the wire mesh demister 5. Meanwhile, the wire mesh demister 5 contains a three-layer wire mesh structure. The top layer is a coarse breaking layer (large-aperture corrugated wire mesh, aperture 8-12mm, wire diameter 0.8-1.2mm), which first breaks up the thick foam layer during sonic impact, preventing a large amount of foam from directly clogging the lower fine mesh. The middle layer is a transition layer (medium-aperture plain weave wire mesh, aperture 4-6mm, wire diameter 0.6-0.8mm), which receives the medium-sized foam particles after the upper layer is broken up and refined by secondary sonic impact, while also buffering the gas. The bottom layer is a fine trapping layer (fine-aperture dense weave wire mesh, aperture 2-3mm, wire diameter 0.3-0.5mm), which captures fine droplets. Combined with sonic vibration, it prevents the fine mesh from clogging and improves separation accuracy.

[0034] After the equipment finishes working, the separated gas is discharged from the gas phase outlet 12, and the liquid that has settled to the bottom of the tank is discharged through the liquid phase outlet 13 at the bottom of the tank, thus achieving efficient gas-liquid separation and completing the entire separation process.
