Description

Technical Field

[0001] This invention relates to the field of packed tower technology, and more specifically, to a gas packed tower based on ultrasonic guided waves. Background Technology

[0002] Gas packed towers are widely used in chemical, petroleum, and environmental protection fields to achieve mass transfer processes between gas and liquid phases, such as absorption, desorption, and distillation. Mass transfer efficiency is a key indicator of the performance of gas packed towers, directly affecting product quality, production efficiency, and energy consumption. However, traditional mass transfer efficiency monitoring methods usually require offline sampling and analysis, which is not only cumbersome and time-consuming but also cannot reflect the dynamic changes in mass transfer within the tower in real time. Once problems such as a decline in mass transfer efficiency occur within the tower, it is difficult to detect them in time and take effective measures to adjust them, which may lead to production accidents or substandard product quality.

[0003] Existing technologies employ ultrasonic guided wave monitoring to monitor the interior of packed towers. However, ultrasonic guided waves generate ultrasonic waves within the tower, causing slight fluctuations that have little impact on the packing material and the gas. In contrast, the water mist sprayed from the nozzle consists of numerous tiny water droplets suspended in the air. When vibration is applied to the air containing the water mist, these small particles gain additional kinetic energy, intensifying their movement. This significantly increases the collision frequency between the previously relatively dispersed particles, ultimately causing the water mist to condense into droplets and fall. This reduces the gas-liquid contact area, resulting in lower gas-liquid two-phase mass transfer efficiency.

[0004] Therefore, it is of great practical significance to develop a packed tower that can monitor the mass transfer efficiency of a gas packed tower in real time and accurately without reducing the mass transfer efficiency. Summary of the Invention

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a gas packed tower based on ultrasonic guided waves, which solves the technical problem in the prior art that the ultrasonic waves emitted by ultrasonic guided waves will affect the liquid at the nozzle to condense into water droplets, reduce the gas-liquid contact area, and reduce the mass transfer efficiency.

[0006] According to one aspect, at least one embodiment of this disclosure provides a gas-filled tower based on ultrasonic guided waves, including a tower body and a liquid spraying assembly, a packing assembly, and an air inlet assembly arranged sequentially from top to bottom in the tower body along a vertical direction; it also includes a turntable component, which is rotatably disposed in the tower body, the turntable component being located vertically between the liquid spraying assembly and the packing assembly, the turntable component having a vertically disposed mounting hole, a mesh body being vertically reciprocatingly slidably disposed in the mounting hole, the mesh body having a plurality of uniformly distributed through holes, and the mesh body rotating with the turntable component.

[0007] As a further technical solution, the mesh body also has several protrusions, which are evenly distributed around the periphery of the mesh body; it also includes a driving member, which is disposed on the inner wall of the tower body and is used to contact the protrusions. The mesh body slides in the vertical direction. One end of the elastic member is connected to the turntable member, and the other end of the elastic member is connected to the mesh body. The elastic member is used to drive the mesh body to reset.

[0008] As a further technical solution, the protrusion has an inclined surface, and the driving member contacts the inclined surface to drive the mesh to move in the vertical direction.

[0009] As a further technical solution, the air intake assembly includes an air intake cylinder, which has an air intake chamber, an air inlet, and an air outlet. The air inlet and the air outlet are both connected to the air intake chamber. The air inlet is located on the side of the air intake cylinder, and a plurality of air outlets are evenly distributed on the top of the air intake cylinder. The air intake cylinder also has a liquid infusion hole that passes through the air intake cylinder. A plurality of liquid infusion holes are evenly distributed on the air intake cylinder. A sliding member is vertically slidably disposed at the air outlet, and the sliding member is used to open or close the air outlet.

[0010] As a further technical solution, the air inlet cylinder has several connecting holes, which are respectively connected to the air outlet. The sliding member slides vertically to contact or separate from the outlet end of the connecting hole. The transverse cross-section of the sliding member is an annular shape, and the transverse cross-sectional area of ​​the sliding member gradually increases from top to bottom vertically.

[0011] As a further technical solution, the outer wall of the connecting hole has a plurality of spaced blocking portions, and the inner wall of the sliding member has an annular portion. The blocking portions are used to contact the annular portion and prevent the sliding member from disengaging from the air outlet.

[0012] As a further technical solution, the spraying assembly includes a liquid inlet pipe disposed in the tower body, and a plurality of spray nozzles, all of which are connected to the liquid inlet pipe and are evenly distributed along the horizontal direction.

[0013] As a further technical solution, the packing assembly includes a frame, which is disposed within the tower body, and the packing components are disposed within the frame.

[0014] As a further technical solution, a drive motor is also included, which is mounted on the tower body. The output end of the drive motor is connected to the turntable component. The ultrasonic transducer is mounted on the outer wall of the tower body, and a plurality of ultrasonic transducers are evenly distributed vertically on the tower body.

[0015] The beneficial effects of the embodiments disclosed herein are as follows:

[0016] In this disclosure, after monitoring the tower body using ultrasonic guided waves, the ultrasonic waves generated by the ultrasonic guided waves affect the water mist sprayed by the liquid spraying component, causing the water mist to condense into water droplets. The water droplets fall onto the rotating mesh, and under the combined action of centrifugal force and the through holes of the mesh, the liquid is dispersed into finer droplets, increasing the contact area with the rising gas below and promoting gas-liquid mass transfer. Through the setting of the rotating disc and the mesh, the gas-liquid contact area is effectively increased, and the mass transfer efficiency is improved. Attached Figure Description

It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0028] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0029] like Figures 1-4As shown, according to one aspect, at least one embodiment of this disclosure provides a gas-filled tower based on ultrasonic guided waves, including a tower body 1 and a liquid spraying assembly 2, a packing assembly 3, and an air inlet assembly 4 arranged sequentially from top to bottom in the tower body 1 in a vertical direction; it also includes a turntable 5, which is rotatably disposed in the tower body 1, and is located vertically between the liquid spraying assembly 2 and the packing assembly 3. The turntable 5 has a vertically disposed mounting hole 501, and a mesh 6 is vertically reciprocatingly disposed in the mounting hole 501. The mesh 6 has a plurality of uniformly distributed through holes 601, and the mesh 6 rotates with the turntable 5.

[0030] In this embodiment, after monitoring the tower body 1 using ultrasonic guided waves, the ultrasonic waves generated by the ultrasonic guided waves affect the water mist sprayed by the liquid spraying component 2, causing the water mist to condense into water droplets. The water droplets fall onto the rotating mesh 6. Under the combined action of centrifugal force and the through holes 601 of the mesh 6, the liquid is dispersed into finer droplets, increasing the contact area with the rising gas below and promoting gas-liquid mass transfer. Through the arrangement of the turntable component 5 and the mesh 6, the gas-liquid contact area is effectively increased, and the mass transfer efficiency is improved.

[0031] Furthermore, the mesh body 6 also has a plurality of protrusions 602, which are evenly distributed around the periphery of the mesh body 6; it also includes a driving member 7, which is disposed on the inner wall of the tower body 1, and is used to contact the protrusions 602. The mesh body 6 slides in the vertical direction. One end of the elastic member 8 is connected to the turntable 5, and the other end of the elastic member 8 is connected to the mesh body 6. The elastic member 8 is used to drive the mesh body 6 to reset.

[0032] In this embodiment, the driving member 7, by contacting the protrusion 602, overcomes the elastic force of the elastic member 8 and pushes the mesh 6 to slide vertically. When the driving member 7 stops working, the elastic force of the elastic member 8 causes the mesh 6 to return to its original position, thereby realizing the reciprocating sliding of the mesh 6 along the vertical direction, changing the flow path and dispersion effect of the liquid on the mesh 6. To prevent the liquid from condensing on the mesh 6, during the rotation of the mesh 6 driven by the turntable 5, the driving member 7 on the inner wall of the tower body 1 will intermittently contact the protrusion 602 on the mesh 6, thereby causing the mesh 6 to reciprocate vertically, causing the liquid that has not been thrown off the mesh 6 to be thrown downwards onto the surface of the mesh 6, thereby dispersing the liquid into smaller droplets through centrifugal force, increasing the contact area with the lower part, allowing the gas and liquid to fully contact each other, and improving the mass transfer efficiency.

[0033] Furthermore, the protrusion 602 has an inclined surface 621, and the driving member 7 contacts the inclined surface 621 to drive the mesh body 6 to move in the vertical direction.

[0034] In this embodiment, the driving component 7 contacts the inclined surface 621, and its force is decomposed into components along the direction of the inclined surface 621 and perpendicular to the direction of the inclined surface 621. The component along the direction of the inclined surface 621 causes the protrusion 602 to drive the mesh body 6 to move vertically, thereby adjusting the position of the mesh body 6. The design of the inclined surface 621 makes the vertical movement of the mesh body 6 more stable and precise, which helps to optimize the mass transfer process and improve the stability of product quality.

[0035] Furthermore, the air intake assembly 4 includes an air intake cylinder 401, which has an air intake chamber 411, an air inlet 412, and an air outlet 413. The air inlet 412 and the air outlet 413 are both connected to the air intake chamber 411. The air inlet 412 is located on the side of the air intake cylinder 401. A plurality of air outlets 413 are evenly distributed on the top of the air intake cylinder 401. The air intake cylinder 401 also has a liquid infusion hole 414 that passes through the air intake cylinder 401. A plurality of liquid infusion holes 414 are evenly distributed on the air intake cylinder 401. The sliding member 402 is slidably disposed vertically at the air outlet 413. The sliding member 402 is used to open or close the air outlet 413.

[0036] In this embodiment, due to the design of the inlet 412, the air pressure near the inlet 412 is always greater than the air pressure away from the inlet 412, thus preventing the gas from being evenly distributed throughout the entire tower body 1. The gas enters the inlet chamber 411 from the inlet 412. By using a sliding member 402, the gas can accumulate in the inlet chamber 411. When the gas pressure in the inlet chamber 411 reaches a certain value, the pressure will push against the weight of the sliding member 402, lifting the adjusting member, allowing the gas to enter the tower body 1 evenly. This ensures uniform contact between the gas and the liquid above, controlling the flow rate and velocity of the gas entering the packing layer. The liquid inlet 414 allows the liquid falling from above to reach the bottom of the tower body 1 and be discharged from there. The liquid inlet 414 is separated from the inlet chamber 411, preventing the gas from being obstructed by the liquid. Liquid falling onto the upper surface of the inlet cylinder 401 will fall through the liquid inlet 414.

[0037] Furthermore, the air inlet cylinder 401 has a plurality of connecting holes 415, which are respectively connected to the air outlet 413. The sliding member 402 slides vertically to contact or separate from the outlet end of the connecting hole 415. The transverse cross-section of the sliding member 402 is an annular, and the transverse cross-sectional area of ​​the sliding member 402 gradually increases from top to bottom vertically.

[0038] In this embodiment, the slider 402 slides vertically. By contacting or separating from the outlet end of the connecting hole 415, the gas can be discharged from the outlet 413 at the same pressure. The cross-section of the slider 402 is annular, which allows the slider 402 to seal the air inlet chamber 411 when it is not disengaged from the connecting hole 415. When the slider 402 is lifted by air pressure, the gas can be sent out between the slider 402 and the outer wall of the connecting hole 415, thereby achieving uniform gas delivery. The cross-sectional area of ​​the slider 402 gradually increases from top to bottom vertically, which makes the opening between the slider 402 and the connecting hole 415 larger as the slider 402 moves upward, thereby accelerating the discharge of gas and reducing the air pressure in the air inlet chamber 411.

[0039] Furthermore, the outer wall of the connecting hole 415 has a plurality of spaced blocking portions 611, and the inner wall of the sliding member 402 has an annular portion 421. The blocking portions 611 are used to contact the annular portion 421, and the blocking portions 611 prevent the sliding member 402 from disengaging from the air outlet 413.

[0040] In this embodiment, the blocking part 611 and the annular part 421 cooperate with each other. When the slider 402 slides upward to a certain position, the blocking part 611 contacts the annular part 421, restricting the slider 402 from continuing to move upward and preventing it from leaving the air outlet 413. The blocking part 611 only prevents the slider 402 from leaving the air outlet 413 and does not affect the exhaust speed of the gas.

[0041] Furthermore, the spraying assembly 2 includes a liquid inlet pipe 201, which is disposed inside the tower body 1. There are several nozzles 202, all of which are connected to the liquid inlet pipe 201 and are evenly distributed in the horizontal direction.

[0042] In this embodiment, the liquid enters the inlet pipe 201 under pressure and is sprayed out through the nozzle 202 to form a mist, providing favorable conditions for gas-liquid mass transfer. The design of the spray assembly 2 ensures uniform distribution of the liquid within the tower, increases the gas-liquid contact area, improves mass transfer efficiency, and helps to enhance the absorption effect.

[0043] Furthermore, the packing assembly 3 includes a frame 301, which is disposed within the tower body 1, and the packing element 302 is disposed within the frame 301.

[0044] In this embodiment, the gas and liquid come into contact on the surface of the packing element 302. The specific surface area and porosity structure of the packing increase the gas-liquid contact time and area, promoting the mass transfer process. The packing assembly 3 provides an efficient environment for gas-liquid mass transfer, and the use of corrugated metal mesh packing improves mass transfer efficiency, contributing to the efficient execution of separation processes such as distillation.

[0045] Furthermore, it also includes a drive motor 9, which is mounted on the tower body 1. The output end of the drive motor 9 is connected to the turntable 5. The ultrasonic transducer 10 is mounted on the outer wall of the tower body 1, and a plurality of the ultrasonic transducers 10 are evenly distributed vertically on the tower body 1.

[0046] In this embodiment, the drive motor 9 drives the turntable 5 to rotate, causing the mesh 6 to rotate as well, promoting liquid dispersion and mass transfer. The ultrasonic transducer 10 emits ultrasonic guided wave signals. The signals propagate within the tower and are reflected or refracted when encountering gas-liquid interfaces, packing materials, etc. The received signals contain information about the mass transfer status within the tower, and mass transfer efficiency can be monitored by analyzing the signals. The drive motor 9 and the ultrasonic transducer 10 ensure the stable operation of the packed tower and real-time monitoring of mass transfer efficiency.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
