Description

Technical Field

[0001] This invention relates to the field of gas-liquid treatment technology of water washing towers, and specifically to a high-efficiency water washing tower. Background Technology

[0002] High-efficiency water scrubbing towers are core gas-liquid mass transfer devices in the fields of industrial waste gas purification, chemical absorption, and particulate matter removal. Gas is introduced into the tower through the bottom inlet pipe and flows upward, forming a countercurrent contact with the absorbent liquid sprayed down from the liquid distributor at the top of the tower. The gas-liquid mass transfer and pollutant removal process is completed by relying on the packing layer or tower plate. The initial flow field quality of the gas entering the tower, including the uniformity of the airflow velocity across the entire cross section, turbulence, and the pre-dispersion state of particles and droplets, directly determines the degree of sufficient gas-liquid contact and absorption efficiency in the tower, and is the core control point for optimizing the performance of water scrubbing towers. In existing technologies, the connection between the inlet pipe and the tower body, as well as the initial gas distribution within the tower, often employs a direct connection between the pipe opening and a gas distribution plate or guide cone within the tower. The working principle is that gas enters the tower body directly through the inlet pipe, impacts the distribution plate or guide cone, and then diffuses outwards before turning upwards into the packing layer or spray area. The distribution plate applies flow resistance to the airflow through its perforations, attempting to achieve a uniform redistribution of the airflow across the entire cross-section. However, as the gas flows within the inlet pipe, a low-velocity laminar boundary layer forms near the pipe wall. This boundary layer persists along the tower wall after entering the tower body with the airflow, resulting in a slow gas replacement rate near the tower wall and creating a weak area for gas-liquid contact. Conventional distribution plates can only passively redistribute the airflow through resistance, unable to actively disrupt the boundary layer structure, thus limiting further improvements in gas-liquid contact efficiency. Summary of the Invention

The flat rack and the receiving slot are connected by a protective shell, which is used to cover and protect the driven wheel, belt and receiving slot.

[0012] The technical effects and advantages provided by the present invention in the above technical solution are as follows: 1. In this invention, the arc-shaped protrusion of the spiral pusher is arranged perpendicularly to the incoming gas flow. After the gas flow impacts the arc-shaped protrusion head-on, a local high-pressure stagnation zone is formed in front of the arc-shaped front. Then, it diffuses radially in all directions along the arc-shaped front. This impact diffusion process can cause large-diameter droplets or agglomerated particles carried in the gas flow to be broken by inertial impact on the arc-shaped front. After the gas flow is transported to the inner cavity of the partition ring through the inner liner tube, it is divided into two paths: one path flows normally along the inner wall of the partition ring, and the other path is led out to the outer cavity of the partition ring through the inclined gas distribution chamber. It flows downstream along the annular gap channel between the outer wall of the partition ring and the inner wall of the middle section pipe. After the annular gap gas flow passes through the partition ring, it forms an annular jet on the back flow side of the ring and is close to the boundary layer region of the inner wall of the middle section pipe. This can forcibly strip away the low-velocity laminar boundary formed at the pipe wall and replace it with fresh gas flow with high turbulence. This disperses the agglomerated particles and droplets in the gas flow, improves the uniformity of the circumferential distribution of the gas flow in the tower, ensures the uniformity of the gas distribution before it reaches the liquid distributor, and is conducive to efficient gas-liquid contact. 2. The present invention drives the fan partition frame to rotate synchronously along the inside of the front end tube by rotating the spiral push rod. When the rotating airflow reaches the end of the inner liner tube, the fan partition frame and the first support ring convert the axial velocity component of the airflow into radial and axial components, thereby forming a further homogenization and guiding effect on the airflow. 3. In this invention, the rotation of the centering ring cylinder synchronously drives the rotation of the guide slide groove. The corrugated trajectory inside the guide slide groove pushes the limiting cone column to make horizontal reciprocating motion along the limiting groove. Driven by the corrugated trajectory, the limiting cone column produces non-uniform horizontal reciprocating motion, which in turn drives the horizontal column to slide directionally along the receiving ring frame and the partition ring through the slide rod. Finally, it pushes the inner lining slide plate to make reciprocating motion along the inside of the air distribution chamber. The inner lining slide plate can frequently change the flow opening of the air distribution chamber in a short time, so that the airflow produces an intermittent pulsating effect, which greatly improves the dispersion uniformity of particles in the airflow. 4. In the reciprocating motion of the front end of the inner lining slide plate, the present invention not only changes the flow area of ​​the air distribution chamber, but also dynamically changes the incident guidance of the airflow into the air distribution chamber. When the inner lining slide plate is pushed outward, its end guides more airflow into the depth of the inclined groove, enhancing the swirling flow. When the push rod is retracted, the airflow flows closer to the outside of the groove opening. This dynamic guidance causes the airflow direction entering the middle section of the pipe to oscillate slightly in the circumferential direction, further disrupting the steady flow structure on the pipe cross section and eliminating the dead zone in the central low turbulence zone. 5. In this invention, the continuous bending surface at the top of the flat frame is inclined relative to the middle section pipe. The airflow moving from the middle section pipe and the partition ring does not move vertically to the bending surface, but cuts in at an inclined angle. The bending surface converts part of the axial kinetic energy of the airflow into radial flow that unfolds along the inclined surface. At the same time, the peaks and valleys of the continuous bending cause the airflow to undergo multiple acceleration and deceleration turns on the inclined surface, transforming the concentrated swirling flow into a large-area diffuse turbulence. 6. This invention utilizes the staggered movement of the second and first actuating rods along the outside of the flattening frame, i.e., staggered phase difference. The staggered appearance of the second and first actuating rods on the outside of the flattening frame generates a spatially asymmetrical airflow pulsation. Under the pressure difference, the droplets and particles in the airflow are repeatedly pushed and pulled laterally, increasing their relative sliding velocity with the gas phase. As the airflow moves from the edge area of ​​the inner wall of the tower towards the center area, combined with the radial expansion of the inclined surface of the flattening frame, the gas-liquid distribution across the entire tower cross-section becomes more uniform, effectively improving the contact area and reaction mass transfer efficiency of the sprayed liquid and gas in the liquid distributor.

[0016] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0017] This invention provides, for example Figure 1 , Figure 2 , Figure 3 and Figure 4 The high-efficiency water washing tower shown includes a tower body 1, a liquid distributor 11 and a middle section pipe 12. A support frame 13 is fixedly connected to the bottom of the tower body 1, and a front end pipe 14 is fixedly connected to the top of the support frame 13. A gas distribution component 2 is provided between the middle section pipe 12 and the front end pipe 14. The gas distribution component 2 is used to turbulent the gas inside the middle section pipe 12 and to fully mix and contact the gas inside the middle section pipe 12 with the liquid inside the tower body 1. The gas distribution assembly 2 includes a partition ring 21 installed inside the middle section pipe 12 and a spiral push rod 25 rotatably installed inside the front end pipe 14. The inclined surface of the spiral push rod 25 forms an arc-shaped protrusion. A receiving ring frame 22 is fixedly connected between the partition ring 21 and the middle section pipe 12, and the receiving ring frame 22 keeps the partition ring 21 hollow inside the middle section pipe 12. Several gas distribution chambers 24 communicating with the interior are obliquely opened on the outside of the partition ring 21. A first servo motor 26 is fixedly connected to one end of the front end pipe 14, and the first servo motor 26 is used to drive the spiral push rod 25 to rotate. An inner liner pipe 23 is connected between the front end pipe 14 and the partition ring 21. One end of the inner liner pipe 23 is fixedly connected to the inner wall of the partition ring 21, and the other end extends into the interior of the front end pipe 14, so that the partition ring 21 and the front end pipe 14 are internally connected through the inner liner pipe 23. The specific structure and working principle of the tower body 1 and the liquid distributor 11 are existing technologies, and will not be described in detail in this application. The current gas treatment process of the water washing tower is as follows: The gas to be treated enters the tower body 1 through the front-end pipe 14 and the middle pipe 12. Before entering the front-end pipe 14, the gas first flows through the gas distributor, which is usually a perforated plate or guide cone structure. It can forcibly disperse and redistribute the high-speed gas flow that enters in a concentrated manner, so that the gas flow flows upward along the entire cross section of the tower body 1 at a relatively uniform flow rate. At the same time, the circulating pump at the bottom of the tower pressurizes the washing liquid (clean water or solution containing chemical agents) and then transports it through the pipeline to the liquid distributor 11 at the top of the tower. The liquid distributor 11 evenly disperses the single-entry liquid flow into multiple fine jets or droplets, and sprays them evenly onto the entire top surface of the packing bed below. Under the action of gravity, the washing liquid flows downward along the packing, wets the surface of the packing and forms a constantly renewed extremely thin liquid film. The gas passes through the packing channel filled with liquid film from bottom to top, and the gas and liquid phases complete contact mass transfer.

The outer side of the inner liner tube 23 is fixedly sleeved with a second support ring 35, and the outer side of the toothed ring 34 extends into the interior of the second support ring 35, and the extended part forms a movable fit with the inner wall of the second support ring 35. A disturbance wall assembly 4 adapted to the gas distribution chamber 24 is provided between the second support ring 35 and the partition ring 21, and the disturbance wall assembly 4 is used to guide the gas distribution inside the gas distribution chamber 24. The air distribution chamber 24 is internally slidably connected to an inner liner slide plate 41 and a gear 48 rotatably connected to one end of the second support ring 35. The gear 48 and the gear ring 34 are meshed. One end of the inner liner slide plate 41 is fixedly connected to a horizontal column 42. One end of the horizontal column 42 passes through the partition ring 21 and the receiving ring frame 22 in sequence and is fixedly connected to a slide rod 44. The slide rod 44 is designed as a T-shaped structure. A reciprocating assembly is provided between gear 48 and slide bar 44, and the reciprocating assembly is used to drive the inner liner slide plate 41 to reciprocate and finely adjust within the air distribution chamber 24. There are three sets of air distribution chambers 24, and the number of the baffle assembly 4 corresponds to the number of air distribution chambers 24 and is arranged accordingly. The outer wall of the inner liner ring frame 32 is movably engaged with the inner wall of the front end tube 14, and the inner wall is fixedly connected to the outer wall of the fan partition frame 31, which can ensure that the fan partition frame 31 rotates stably inside the front end tube 14. When the guide slide 46 is engaged with the limiting cone 47, the change in the helix angle of its corrugated trajectory can produce a significant force amplification effect. A large thrust can be output in the small helix angle section of the corrugation to meet the driving requirements of the load condition. In the no-load return stage, the large helix angle section can achieve rapid reset movement. At the same time, when the inner liner slide plate 41 is pushed in the opposite direction by the airflow reaction force, the corrugated trajectory profile of the guide slide 46 has a self-locking characteristic, which can prevent the inner liner slide plate 41 from being pushed back by the airflow. The reciprocating assembly includes a limiting groove 43 opened on the outside of the inner liner tube 23 for the slide rod 44 to move horizontally back and forth, and a centering column 49 fixedly connected to one end of the gear 48.

The installation positions of the two are staggered. At the same time, the number of support column 61, side connecting plate 63, first shaft column 64 and connecting arm 65 are matched with the number of first actuating rod 53 and first saddle plate 55 and second actuating rod 54 and second saddle plate 56, and they are matched with each other.

[0020] Working principle: When using: refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when it is necessary to bring the gas into contact with the liquid inside tower 1 in order to treat harmful substances in the gas; First, external gas enters the cavity through the inlet of the front-end pipe 14. The first servo motor 26 outputs driving force, driving the spiral push rod 25 to rotate inside the front-end pipe 14. The arc-shaped protrusion of the spiral push rod 25 is perpendicular to the incoming gas flow. After the airflow impacts the arc-shaped protrusion head-on, a local high-pressure stagnation zone is formed in front of the arc-shaped front. Subsequently, the airflow diffuses radially in all directions along the arc-shaped front. This impact diffusion process can cause large-diameter droplets or particle clusters carried in the airflow to be broken by inertial impact on the arc-shaped front. At the same time, the radial diffusion of the airflow can stretch the rotating flow core formed by the turbulence ring groove towards the pipe wall, expand the range of the vortex core, and enhance the gas exchange between the center and the edge regions. The rotation of the spiral push rod 25 synchronously drives the fan-shaped support frame 31 to rotate inside the front-end pipe 14. When the rotating airflow reaches the end of the inner liner pipe 23... When the fan-shaped support frame 31 and the first support ring 33 are in place, they can convert the axial velocity component of the airflow into radial and circumferential components, which further guides the airflow. Then the airflow enters the interior of the inner liner tube 23 and is guided by the inner liner tube 23 to the inner cavity of the partition ring 21. After the airflow contacts the partition ring 21, part of it flows normally along the inner wall of the partition ring 21, and the other part is led out to the outer cavity of the partition ring 21 through the inclined gas distribution chamber 24. It flows downstream along the annular gap channel between the outer wall of the partition ring 21 and the inner wall of the middle section pipe 12. After the annular gap airflow flows through the partition ring 21, it forms an annular jet on the annular backflow side of the partition ring 21 and approaches the boundary layer region of the inner wall of the middle section pipe 12. It can forcibly peel off the low-velocity laminar boundary formed on the inner wall of the middle section pipe 12 and replace it with fresh airflow with high turbulence flowing along the wall. refer to Figure 4 , Figure 5 and Figure 6As shown, during the rotation of the fan partition support frame 31, the inner lining ring frame 32 is synchronously driven to rotate along the inner wall of the front end tube 14. The inner lining ring frame 32 makes a circular motion along the outer side of the toothed ring 34, forming a guiding motion between the front end tube 14 and the first support ring 33. The rotation of the inner lining ring frame 32 drives the toothed ring 34 to rotate synchronously along the outer side of the first support ring 33 and the inner side of the second support ring 35. The toothed ring 34 meshes with the gear 48, driving the gear 48 to rotate along the end of the second support ring 35. The rotation of the gear 48 drives the centering column 49 to rotate along the inside of the second support ring 35, thereby driving the centering ring cylinder 45 to rotate synchronously. The rotation of the cylinder 45 synchronously drives the guide slide 46 to rotate. The corrugated trajectory inside the guide slide 46 pushes the limiting cone 47 to move horizontally back and forth along the limiting groove 43. Driven by the corrugated trajectory, the limiting cone 47 produces a non-uniform horizontal back and forth movement, which in turn pushes the slide rod 44 to move synchronously along the limiting groove 43. The slide rod 44 drives the horizontal column 42 to slide directionally along the receiving ring frame 22 and the partition ring 21. The displacement of the horizontal column 42 pushes the inner lining slide plate 41 to move back and forth along the air distribution chamber 24, so that the inner lining slide plate 41 frequently changes the flow opening of the air distribution chamber 24 in a short period of time, so that the airflow produces an intermittent pulsating effect. Figure 7 , Figure 8 , Figure 9 and Figure 10Finally, the airflow inside the partition ring 21 and the middle section pipe 12 continues to flow into the tower body 1. After the airflow enters the tower body 1, the continuous bending surface at the top of the flat frame 52 is arranged at an angle relative to the middle section pipe 12. The airflow flowing out of the middle section pipe 12 and the partition ring 21 does not impact the bending surface perpendicularly, but cuts in at an inclined angle. The bending surface can convert part of the axial kinetic energy of the airflow into radial flow that unfolds along the inclined surface. At the same time, the peak and valley structure of the continuous bending causes the airflow to undergo multiple acceleration and deceleration turns on the inclined surface, transforming the concentrated vortex into a large-area diffuse flow. The second servo motor 73 drives the drive pulley 74 to rotate, and drives the belt 76 to circulate through friction. The belt 76 is stretched taut on the side entering the drive pulley 74, forming a tight side. Within the wrap angle of the drive pulley 74, there is a tension difference between the tight and slack sides. The slight elastic deformation of the belt 76 causes it to produce a small elastic slip on the pulley surface, generating friction in the same direction as the rotation. The drive pulley 74 transmits the rotational tangential force to the belt 76 through this friction, providing kinetic energy to the belt. The belt 76 then rotates. When the driven pulley 75 is reached, the tight-side tension acts on the driven pulley 75, causing it to rotate in a following direction. The driven pulley 75 applies reverse frictional resistance to the belt 76, causing the tension on the side of the belt 76 away from the driven pulley 75 to decrease, forming a slack side. The belt 76 continues to circulate, achieving smooth power transmission through the dynamic tension changes between the tight and slack sides. The rotation of the driven pulley 75 drives the side support rod 72 to rotate synchronously along the inside of the side support 71. The rotation of the side support rod 72 drives the second saddle plate 56 to rotate synchronously with the first saddle plate 55. The rotation of the second saddle plate 56 drives the second connecting rod 66 to make a counterclockwise circular motion. When the second connecting rod 66 makes a circular motion along the outside of the mounting base 51, its outer wall and the inner wall of the connecting arm 65 form a contact fit, pushing the connecting arm 65 to move to the left along the outside of the mounting base 51. The displacement of the connecting arm 65 pushes the first shaft column 64 to move synchronously. During the process of the first shaft column 64 moving to the left under force, it pushes the side connecting plate 63 to drive the outer circular seat 62 to make a circular motion along the outside of the support column 61, thereby driving the second actuating rod 54 to make an arc-shaped motion downward along the top of the flat frame 52. Figure 7 , Figure 8 , Figure 9 and Figure 10As the second saddle plate 56 continues to rotate, the second connecting rod 66 moves from the highest point to the lowest point of the ring along the outer side of the mounting base 51. The interaction between the second connecting rod 66 and the connecting arm 65 changes from pushing to pulling. The second connecting rod 66 pulls the connecting arm 65 to move from left to right. At this time, the connecting arm 65 swings left and right and up and down along the side of the mounting base 51 under the drive of the second connecting rod 66, instead of rotating a full circle with the second connecting rod 66. The relative position of the second connecting rod 66 and the second saddle plate 56 changes from horizontal to coincident. During the movement of the connecting arm 65, the first shaft column 64 is pulled to move synchronously, causing the side connecting plate 63 and the outer circular seat 62 to move in the opposite direction along the outer side of the support column 61, so that the second actuating rod 54 moves and resets along the outer side of the flat frame 52. This cycle repeats. Similarly, the rotation of the side support rod 72 synchronously drives the first saddle plate 55 to rotate. The rotation of the first saddle plate 55 drives the second connecting rod 66 to make a clockwise circular motion. When the second connecting rod 66 moves along the outside of the mounting base 51, its outer wall and the inner wall of the connecting arm 65 form a contact fit, pulling the connecting arm 65 to move to the right along the outside of the mounting base 51. The displacement of the connecting arm 65 drives the first shaft column 64 to move synchronously. During the process of the first shaft column 64 moving to the right under the force, it pulls the side connecting plate 63 to drive the outer circular seat 62 to make a circular motion along the outside of the support column 61, and then drives the first actuating rod 53 to make an arc-shaped motion upward along the top of the flat frame 52. As the first saddle plate 55 continues to rotate, the second connecting rod 66 moves from the highest point to the lowest point of the ring along the outer side of the mounting base 51. The interaction between the second connecting rod 66 and the connecting arm 65 changes from pulling to pushing. The second connecting rod 66 pushes the connecting arm 65 to move from right to left. At this time, the connecting arm 65, driven by the second connecting rod 66, swings left and right and up and down along the side of the mounting base 51, instead of rotating a full circle with the second connecting rod 66. The relative position of the second connecting rod 66 and the first saddle plate 55 changes from coincident to horizontal. During the movement of the connecting arm 65, it pushes the first shaft column 64 to move synchronously, causing the side connecting plate 63 and the outer circular seat 62 to move in opposite directions along the outer side of the support column 61. The first actuating rod 53 is moved and reset along the outside of the flat frame 52, and this cycle is repeated. The first actuating rod 53 and the second actuating rod 54 move alternately along the outside of the flat frame 52. There is a phase difference between the two, which forms an asymmetrical airflow pulsation on the surface of the flat frame 52. The droplets and particles in the airflow are repeatedly pushed and pulled laterally under the pressure difference, and the relative sliding velocity with the gas phase increases. Combined with the radial expansion effect of the inclined surface of the flat frame 52, the gas-liquid distribution of the entire tower cross section becomes more uniform as the airflow diffuses from the edge area of ​​the inner wall of the tower body 1 to the center area. This can effectively improve the contact area and reaction mass transfer efficiency of the liquid sprayed by the liquid distributor 11.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
