Description

Technical Field

[0001] This invention relates to the field of industrial waste gas purification and gas-liquid separation technology, specifically to a novel micro-vortex demister. Background Technology

[0002] Many industrial processes, such as wet desulfurization, chemical absorption, and gas cooling, generate large amounts of saturated waste gas carrying liquid droplets. If these waste gases are not effectively separated from their liquid components, the droplets can cause corrosion of downstream equipment, pipe blockage, catalyst poisoning, loss of valuable media, and environmental pollution. Therefore, the performance of the demister, as a critical end-of-line separation device, directly affects the operating efficiency, energy consumption, and reliability of the entire system.

[0003] Traditional demisting technologies, such as baffle plate, wire mesh, and classic "S"-shaped corrugated plate demisters, have revealed several inherent defects in long-term application. First, the working principle of these demisters largely relies on sudden changes in airflow direction or the inertial impaction of droplets through narrow channels, meaning their efficient operating range often corresponds to a relatively narrow gas velocity range. When the velocity is too low, the droplets lack sufficient inertia to effectively separate from the airflow; when the velocity is too high, the captured droplets are easily re-entrained by the high-speed airflow, resulting in a "secondary liquid lifting" phenomenon, severely limiting the equipment's adaptability to fluctuations in operating conditions. Second, the separation process in traditional demisters is often a gas-liquid countercurrent or vertical impact mode, with the droplets falling in the opposite direction to the rising airflow. This antagonistic flow pattern itself limits further improvement in separation efficiency and increases system pressure drop. Furthermore, wire mesh packing or complex baffle channels are easily clogged by solid particles or sticky substances in the exhaust gas, which not only leads to a sharp increase in resistance and energy consumption, but also requires frequent shutdowns for cleaning, resulting in high maintenance costs and affecting production continuity. Therefore, since it does not meet the existing needs, we have proposed a new type of micro vortex demister. Summary of the Invention

[0004] To address these issues, the present invention provides a novel micro-vortex demister to solve the aforementioned problems in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: According to a first aspect of the present invention, a novel micro vortex demister includes a cylindrical tank, the tank being divided into an upper chamber and a lower chamber by a fixing plate, the lower chamber having a tangential air inlet pipe on its side wall, a central pipe connecting the upper and lower chambers at the center of the fixing plate, the upper chamber having an air outlet and an exhaust port, and the lower chamber having a vent at its bottom. The bottom of the fixed plate is provided with at least one set of annular airflow guiding channels formed by dividing concentric annular plates. At least one of the airflow guiding channels is provided with multiple micro vortex guiding plates on its inner and outer walls. The micro vortex guiding plates are arc-shaped and their arc concave surfaces are set to cut the rotating airflow flowing through them, either facing or laterally, in order to generate local micro vortices in the macroscopic rotating flow to promote the collision and coalescence of droplets. The annular plate is provided in three parts, which are divided into three concentric arc plates by opening fan-shaped grooves, thereby forming the first, second and third airflow guiding channels from the outside to the inside; the micro vortex guide vanes are provided on the inner and outer side walls of the second and third airflow guiding channels.

[0006] Furthermore, the micro-vortex guide vanes located on the inner and outer side walls of the same airflow guide channel are distributed in an alternating manner.

[0007] Furthermore, each of the micro vortex guide vanes is rotatably connected to the arc-shaped plate via a connecting structure. The connecting structure includes a U-shaped frame fixed to the arc-shaped plate. The micro vortex guide vane is rotatably connected to the U-shaped frame via a connecting sleeve and a vertical rotating shaft. A spiral spring is provided between the connecting sleeve and the vertical rotating shaft to enable the micro vortex guide vane to adaptively adjust its angle of attack under the balance of aerodynamic force and spring force.

[0008] Furthermore, the U-shaped frame is rotatably connected to the mounting platform fixed on the arc plate via a connecting shaft, allowing the U-shaped frame and its internal micro-vortex guide vane unit to swing around the connecting shaft axis.

[0009] Furthermore, the U-shaped frames of the multiple micro vortex guide vanes are linked together by a series rod and a series frame to form at least one linkage group, ensuring that the swing of all micro vortex guide vanes in the linkage group is synchronized.

[0010] Furthermore, the micro-vortex guide vane on the outer wall of the second channel is defined as the first guide vane, and the one on its inner wall is defined as the second guide vane; the one on the outer wall of the third channel is defined as the third guide vane, and the one on its inner wall is defined as the fourth guide vane; the first guide vane and the third guide vane are linked by a series rod, and the second guide vane and the fourth guide vane are linked by another series rod.

[0011] Furthermore, the connecting shafts of the first guide vane and the fourth guide vane extend out of the arc-shaped plate they are located on, and a helical gear is fixedly connected to the end of each shaft.

[0012] Furthermore, helical gear one meshes with helical gear two, which is fixed inside the tank.

[0013] Furthermore, all the arc-shaped plates are connected in series as a whole by a ring-shaped connecting frame. The connecting frame is rotatably connected to the connecting sleeve at the bottom of the fixed plate through a bearing, and is provided with a rotary drive mechanism driven by a drive motor through a worm gear and a turbine, which is used to drive all the arc-shaped plates and the mounting platform on them to revolve around the central tube axis.

[0014] Furthermore, when the drive motor drives the arc plate to revolve, under the constraint of the fixed helical gear two, the connecting shaft of the first and fourth guide vanes is forced to rotate, which in turn drives the U-shaped frame of all micro vortex guide vanes to swing synchronously through the series rod, so as to uniformly change the preset initial angle of each micro vortex guide vane.

[0015] Furthermore, the distances from the helical gear at the end of the connecting shaft of the first guide vane to the center of rotation are different from those from the helical gear at the end of the connecting shaft of the fourth guide vane. This results in the rotation angles of the first and third guide vanes being greater than those of the second and fourth guide vanes when the connecting frame rotates by the same angle, thereby achieving differentiated gradient adjustment of guide vanes at different radial positions.

[0016] Furthermore, the differentiated gradient adjustment allows the first and third guide vanes located in the outer airflow channel to be adjusted at a larger angle to meet the capture or drag reduction requirements of the high-speed, high-centrifugal region; while the second and fourth guide vanes located in the inner airflow channel are adjusted at a smaller angle to stabilize the flow field near the core region and promote the coalescence of fine droplets.

[0017] The present invention has the following advantages: 1. This novel micro-vortex demister features a concentric annular airflow guiding channel with arc-shaped and staggered micro-vortex guide vanes arranged on the channel wall. The tangentially entering airflow is guided to form a strong downward rotating mainstream, while the guide vanes act like a series of precise vortex generators, continuously cutting and disturbing the airflow passing over their surface, generating a large number of high-intensity, small-scale micro-vortices within the macroscopic rotating flow. These micro-vortices greatly enhance the collision, merging, and migration mechanisms between droplets towards the wall, enabling even at high flow velocities, fine droplets can be effectively coalesced and rapidly detached from the airflow under centrifugal force, thus achieving separation efficiency far exceeding that of traditional methods. 2. This novel micro-vortex demister, in its basic structure, features each micro-vortex guide vane that achieves independent adaptive deflection through a spiral spring mechanism. This allows for real-time fine-tuning of the angle in response to local flow velocity changes, automatically balancing separation efficiency and flow resistance under wide loads. A more advanced design utilizes a centralized drive system to control the preset reference angles of all guide vanes. Ingeniously, by employing a helical gear pair and linkage mechanism, this drive system can synchronously but differentially adjust the deflection amplitude of guide vanes at different radial positions. The outer guide vanes can be significantly adjusted to meet the strong capture or drag reduction requirements of the high-speed outer region, while the inner guide vanes undergo small, fine adjustments to maintain the stability of the flow field near the core region. This radial gradient adjustment capability—"large outer amplitude, small inner amplitude"—allows the demister to intelligently match different inlet conditions (such as high-concentration coarse particles or low-concentration fine droplets), enabling flexible switching between various optimal operating modes, such as "primarily capturing on the outer side, ensuring smooth flow on the inner side" to "reducing losses on the outer side, improving efficiency on the inner side," thus elevating overall performance to a new level.

[0020] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.

[0021] Example 1; Reference Figures 1-10 A novel micro-vortex demister includes a cylindrical tank 11, with a fixing plate 13 fixedly installed on the upper inner wall of the cylindrical tank 11, which divides the cylindrical tank 11 into upper and lower chambers. An air inlet pipe 12 is installed on the side wall of the cylindrical tank 11. The output end of the air inlet pipe 12 is connected to the lower cavity. A central pipe 14 is fixedly installed at the bottom center of the fixed plate 13. A vertical through-ventilation channel is opened on the central pipe 14 to connect the upper and lower cavities. The bottom end of the fixed plate 13 is fixedly installed with three annular sleeves of different diameters and concentrically arranged with the central tube 14, which together form the annular plate 18; The bottom end of the fixed plate 13 is fixedly equipped with three annular sleeves of different diameters, which are concentrically arranged with the central tube 14, forming an annular plate 18. Each annular sleeve has fan-shaped grooves arranged in a ring array, thereby dividing the three annular sleeves into three groups of arc plates 181. The three arc plates 181 in the same group are arranged sequentially from the inside to the outside, forming three concentric annular airflow guiding channels between them: the outer wall of the outermost arc plate 181 and the inner wall of the cylindrical tank 11 form the first airflow guiding channel; the inner side of the outermost arc plate 181 and the outer wall of the middle arc plate 181 form the second airflow guiding channel; the inner side of the middle arc plate 181 and the outer wall of the innermost arc plate 181 form the third airflow guiding channel. On the inner and outer side walls of the second airflow guiding channel and the inner and outer side walls of the third airflow guiding channel, micro vortex guide vanes 182 are vertically installed in a fan-shaped array. These micro vortex guide vanes 182 have an arc-shaped structure. The key feature is that the arc-shaped concave surfaces of the micro vortex guide vanes 182 arranged in rows on each side of the channel wall are all designed to cut the downward rotating airflow at that point in the direction of the flow, rather than being completely in the same direction. More specifically, the micro vortex guide vanes 182 located on the inner and outer side walls of the channel are distributed in an alternating manner, thereby forming continuous and asymmetrical disturbance points in the airflow path. When the rotating airflow passes through these annular channels, the staggered micro-vortex guide vanes 182 with their concave surfaces facing the airflow continuously cut and impede the airflow. This design can generate a large number of strong local vortices (i.e., micro-vortices) with different directions and small scales in a stable rotating mainstream. These micro-vortices greatly disrupt the stability of the airflow and create excellent conditions for the collision and coalescence of droplets. The cylindrical tank 11 has an air outlet 15 on the upper cavity side wall and an exhaust port 16 on the top of the upper cavity, which together form the exhaust path of the purified gas. Working principle: During operation, the exhaust gas carrying liquid droplets enters the lower chamber tangentially through the intake pipe 12, forming a high-speed downward rotating mainstream; when the airflow passes through the second and third annular guide channels, it will be continuously acted upon by the micro vortex guide vanes 182 arranged alternately on both sides of the channel. Each micro-vortex guide vane 182 acts like a tiny vortex generator. Its arc-shaped concave surface facing the airflow produces local separation and shearing of the airflow, forming tiny vortices behind it. Due to the staggered arrangement of the micro-vortex guide vanes 182 on both sides, these tiny vortices are unevenly distributed on the cross-section of the channel and interfere with each other, causing the entire flow field to rapidly transform from a steady laminar flow or a large vortex flow into a complex flow field full of violent, random micro-scale turbulence. In this high-intensity microturbulent flow field, the Brownian motion of the fine droplets is greatly enhanced, and the collision frequency and efficiency between droplets of different sizes and between droplets and solid walls are increased by orders of magnitude. The droplets rapidly coalesce and grow, and under the continuous centrifugal force, they are thrown towards the inner wall of the tank 11. The condensed droplets slide down the wall and eventually gather at the bottom of the tank and are discharged from the vent 17. After gas-liquid separation, the clean gas flows to the bottom of the tank and changes direction. It rises through the central tube 14 into the upper chamber and is finally discharged from the outlet 15 and exhaust port 16. Example 2: Basically the same as in Example 1, but further: referring to Figures 1-10A novel micro-vortex demister is described, wherein each micro-vortex guide vane 182 is rotatably connected to its corresponding arc-shaped plate 181 via a connecting structure. This connecting structure includes a U-shaped frame 21 fixedly connected to the arc-shaped plate 181. A connecting sleeve 23 is fixedly connected to one end of the micro-vortex guide vane 182 near the U-shaped frame 21. The inner wall of the connecting sleeve 23 is rotatably connected to the two side walls of the U-shaped frame 21 via a vertical rotating shaft 22. Crucially, both ends of the connecting sleeve 23 are provided with grooves 24, and a spiral spring 25 is installed between the groove 24 and the vertical rotating shaft 22. The two ends of the spiral spring 25 are fixedly connected to the connecting sleeve 23 and the vertical rotating shaft 22, respectively. Working principle: In the absence of wind, the spiral spring 25 keeps the micro-vortex guide vane 182 at a preset optimal angle to the airflow. When the airflow velocity increases, the aerodynamic torque acting on the arc surface of the guide vane increases accordingly. If this torque exceeds the preset torque of the spiral spring 25, it will drive the connecting sleeve 23 to rotate the guide vane 182 around the vertical axis 22, making its arc concave surface more aligned with the airflow direction, thereby reducing local resistance and airflow impact. When the airflow velocity decreases, the restoring torque of the spiral spring 25 drives the guide vane 182 back to its original position. This purely passive adaptive adjustment mechanism allows each guide vane to finely adjust its angle in real time according to the local flow velocity at its location, thereby maintaining a high efficiency in generating micro-vortices and low flow resistance over a wide flow velocity range, improving the working stability and load adaptability of the entire demister. Example 3: It is basically the same as Embodiment 1, except that the U-shaped frame 21 and the arc plate 181 are not fixedly connected, and the supporting structure that supports the arc plate 181 has also changed. First, mounting platforms 26 are provided on the inner and outer side walls of the second and third airflow guiding channels, and the mounting platforms 26 are fixed on the corresponding arc-shaped plates 181 and move accordingly. A connecting shaft 27 is fixedly installed at the outer center of the U-shaped frame 21. The connecting shaft 27 is rotatably connected to the mounting platform 26, and its axis is perpendicular to the mounting platform 26. This means that the entire U-shaped frame 21 and the internal guiding vane unit can swing around the axis of the connecting shaft 27 on the mounting platform 26, and the base of this swing pair (mounting platform 26) moves together with the arc-shaped plate 181. For clarity, the following groupings are defined: the guide vane on the outer wall of the second airflow guide channel is named the first guide vane, and the one on the inner wall is named the second guide vane; the one on the outer wall of the third airflow guide channel is named the third guide vane, and the one on the inner wall is named the fourth guide vane. A series frame 35 is fixedly installed on the outer side of the U-shaped frame 21 of the first and fourth guide vanes; the connecting shaft 27 of the third guide vane extends outward and is fixedly connected to the series frame 35 of the first guide vane through a series rod 36; similarly, the connecting shaft 27 of the second guide vane extends inward and is fixedly connected to the series frame 35 of the fourth guide vane through another series rod 36; this design realizes the swing linkage of the first and third guide vanes, as well as the swing linkage of the second and fourth guide vanes, ensuring that the guide vanes in the same group move completely synchronously; The connecting shaft 27 of the first guide vane extends outward through the outermost arc plate 181, and the connecting shaft 27 of the fourth guide vane extends inward through the innermost arc plate 181. At the end of each of these, a helical gear 38 is fixedly connected; below each helical gear 38, a helical gear 39 is meshed with a helical gear 39 fixedly installed on the internal support of the tank. Three sets of arc-shaped plates 181 are connected in series to form a frame that can rotate as a whole through a ring-shaped connecting frame 31. A connecting sleeve 310 is rotatably connected to the middle of the connecting frame 31 via a bearing. The top of the connecting sleeve 310 is fixed to the bottom of the fixed plate 13 and is fitted onto the outside of the central tube 14. A turbine 32 is fixedly installed on the bottom outer side of the connecting frame 31. Correspondingly, a drive motor 34 is fixedly installed on the inner wall of the cylindrical tank 11. The worm gear 33 connected to its output end meshes with the turbine 32. When the drive motor 34 is started, the turbine 32 is driven through the worm gear 33, thereby driving the entire three sets of arc-shaped plates 181 connected in series by the connecting frame 31 and all the structures on them to slowly revolve around the axis of the central tube 14. Working principle: When adjustment is required, the drive motor 34 is started; the motor drives the connecting frame 31 and all three sets of arc plates 181 connected in series on it to revolve around the central tube 14 through the transmission of the worm gear 33 and the worm 32; since the mounting platform 26 is fixed on the arc plate 181, they revolve together with the arc plate 181; however, the U-shaped frame 21 is rotatably connected to the mounting platform 26 through the connecting shaft 27, and the end of the connecting shaft 27 forms a motion constraint with the fixed tank structure through the helical gear pair composed of helical gear 1 38 and helical gear 2 39; This kinematic relationship leads to a key result: when the arc plate 181 revolves, the fixed helical gear 2 39 forces the helical gear 1 38 meshing with it to rotate, thereby causing the connecting shaft 27 of the first and fourth guide vanes to rotate around its own axis; this rotational motion is precisely transmitted to the linked third and second guide vanes through the connecting rod 36, and is finally converted into the synchronous oscillation of the U-shaped frame 21 of all micro vortex guide vanes 182 around the axis of their respective connecting shaft 27. This oscillation directly changes the initial balance position of the spiral spring 25 between each micro vortex guide vane 182 and the U-shaped frame 21, thus setting the reference angle of the guide vane under the new operating conditions. The operator can control the drive motor 34 to adjust all the guide vanes to the optimal angle at one time and synchronously according to actual needs (such as pursuing extremely high separation efficiency or low system resistance), thereby optimizing the comprehensive performance of the demister under different operating conditions. Meanwhile, the lengths between the two helical gears 38 and the center of rotation are different. Therefore, when the connecting frame 31 rotates, the outer helical gear 38 rotates a greater distance than the inner helical gear 38. Consequently, the rotation angles of the two sets of helical gears are different, resulting in the rotation angles of the first and third guide vanes being greater than those of the second and fourth guide vanes. Applying a larger angle adjustment to the first and third guide vanes (outer group): This allows the outer guide vanes to change their angle of attack more significantly; when enhanced separation is required, they can rotate to a steeper angle of attack to generate stronger shear and more intense micro-vortices, making full use of the high flow velocity and strong centrifugal force field on the outside, ensuring that droplets can be effectively captured and ejected even at high speeds or high loads; conversely, when drag needs to be reduced, they can also rotate to a smoother angle, significantly reducing obstruction to the main flow field; Applying a small angle adjustment to the second and fourth guide vanes (inner group): This ensures that the adjustment of the inner flow field is more precise and gentle; the main function of the inner region is to finely process and stabilize the flow field; the small adjustment range can avoid excessive disturbance to the airflow near the core, prevent the already separated fine droplets from being resuspended due to flow field turbulence, and at the same time moderately enhance the micro eddies to promote the coalescence of residual small droplets on the inner side; When facing coarse separation conditions with high concentrations and large droplets, the system can be driven to deflect the outer guide vanes significantly to enhance collection, while the inner guide vanes are finely adjusted to maintain stability, thus achieving primary collection on the outer side and ensuring unobstructed flow on the inner side. When dealing with fine separation of low concentration and fine droplets, the system can drive the outer guide vanes to deflect appropriately to reduce resistance, and finely adjust the inner guide vanes to improve the coalescence effect, thereby reducing losses on the outer side and increasing efficiency on the inner side.
