Description

Technical Field

[0001] This invention relates to the field of washing tower equipment technology, specifically an adaptive acid-base washing tower. Background Technology

[0002] Waste gas emissions are a significant environmental issue in industrial production. With increasing environmental awareness and increasingly stringent emission standards, efficient waste gas purification has become essential for sustainable enterprise development. Scrubbers, a common waste gas treatment device, remove pollutants from waste gas through spray washing. They offer advantages such as high treatment efficiency and ease of operation, and are widely used in chemical, metallurgical, and electronics industries.

[0003] Traditional devices have the following shortcomings:

[0004] Existing scrubbing towers are generally sufficient for treating conventional waste gases, but they have significant limitations when dealing with high-concentration acid and alkali waste gases. Due to the high pollutant content in these gases, the scrubbing liquid quickly becomes saturated and loses its absorption capacity. To ensure effective scrubbing, existing towers typically use disposable scrubbing liquid, meaning it is not recycled and is immediately discharged after use, with fresh liquid continuously introduced into the spray pipes. While this method guarantees effectiveness, the constant scrubbing efficiency leads to significant waste of scrubbing liquid when waste gas emissions are low, increasing treatment costs. Furthermore, when waste gas emissions increase, the constant scrubbing efficiency of the tower cannot adapt to changes in gas volume, resulting in incomplete scrubbing and environmental damage. In such cases, companies can only maintain purification by reducing production capacity. Therefore, existing scrubbing towers are insufficient to meet the scrubbing needs of high-concentration acid and alkali waste gases. Summary of the Invention

[0005] The purpose of this invention is to provide an adaptive acid-base scrubbing tower to solve the problems mentioned in the background art.

[0011] A connecting plate is movably disposed on one side of the outer wall of the tower body. The first tie rod, the second tie rod, and the third tie rod pass through through holes in the tower body and are connected to one side of the connecting plate.

[0012] Preferably, the rotating partition assembly includes:

[0013] The mounting shaft is symmetrically and movable within the mounting frame, and a flap is provided on the mounting shaft;

[0014] The wall groove is formed on the inner wall of the tower body and located on both sides of the mounting frame. The end of the mounting shaft passes through the mounting frame and is provided with a rotating pin in the wall groove.

[0015] A sliding sleeve is slidably connected to the upper end of the wall groove, and the lower end of the sliding sleeve is connected to the frame wall of the mounting frame through the wall groove by a synchronous bracket.

[0016] A permanent magnet slider is slidably connected inside a sliding sleeve. A push rod is rotatably connected to the lower end of the permanent magnet slider, and the lower end of the push rod is rotatably connected to a rotating pin.

[0017] An electromagnetic bar is installed inside the tower body shell, above the wall groove, to control the movement of the permanent magnet slider.

[0018] Preferably, the clamping assembly includes:

[0019] A top plate is installed on the inner wall of the tower body, and several inner sleeves are provided through the lower end surface of the top plate;

[0020] The lifting groove is located on the inner wall of the tower body, below the top plate. A bottom plate is movably installed inside the lifting groove. Several outer sleeves matching the inner sleeve are opened through the upper surface of the bottom plate. The outer sleeves are sleeved on the outside of the inner sleeve. A through groove for horizontal sliding of the connecting strip is opened on one side of both the top plate and the bottom plate.

[0021] A buffer rod is installed at the upper end of the lifting groove and connected to the base plate.

[0022] The permanent magnet strip is embedded and installed on the outer edge of the base plate to match the electromagnetic strip, which is distributed in a rectangular shape below the lifting groove.

[0023] Preferably, the drive mechanism includes:

[0024] The mounting cover is located on the outer wall of the tower body, outside the connecting plate, and a motor is installed at the end of the mounting cover;

[0029] Preferably, the lower end of the base has a plurality of steel balls movably disposed thereon through ball grooves to reduce friction.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] This invention, by incorporating an adjustment mechanism, enables flexible adjustment of the washing efficiency of the scrubbing tower. When the exhaust gas volume increases or decreases, the washing efficiency is adjusted synchronously by regulating the amount of packing material involved in the washing process. This avoids situations where insufficient exhaust gas volume leads to wasted washing liquid, or excessive exhaust gas volume results in insufficient washing and forced production reduction. Furthermore, when adjusting the packing material amount, the spray volume and spray area of ​​the washing liquid in the spray pipes are also adjusted simultaneously, ensuring that all packing material involved in the washing of the exhaust gas can be effectively wetted, thus better meeting the flexible and ever-changing application needs of current enterprises.

[0032] This invention enables rapid adjustment of the flap angle by incorporating a rotating partition component. When the waste gas discharge changes and the washing efficiency of the scrubbing tower needs to be adjusted, the flap is made perpendicular to the mounting frame, ensuring that the mounting frame can move smoothly horizontally within the packing area and significantly reducing resistance during movement. After adjustment, the flap is rotated back to partition the two sides of the packing area, ensuring the smooth operation of the washing process.

[0033] This invention, by incorporating a pressing component, allows for flexible control and rapid adjustment of the space above the filler, significantly reducing the resistance encountered during the rotation and horizontal movement of the flap, improving movement efficiency, and ensuring the bottom plate can automatically reset after adjustment, thus guaranteeing the pressing effect of the filler during subsequent washing. Furthermore, the entire lifting and lowering of the bottom plate is accomplished by the magnetic force of the electromagnetic strip, which is the same as the rotational power source of the flap, eliminating the need for additional power input, avoiding equipment redundancy, and ensuring the synchronization of their movements.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0052] Please see Figure 1-14 As shown, this invention provides an adaptive acid-base scrubbing tower technical solution: An adaptive acid-base scrubbing tower includes a tower body 1, which is rectangular in shape. A liquid pump 2 and an air inlet pipe 3 are installed on one side of the outer wall of the tower body 1. An exhaust pipe 4 is connected to the upper end of the tower body 1. A demister 5 is fixedly installed at the upper end inside the tower body 1. Several spray pipes 6 connected to the liquid pump 2 are horizontally installed below the demister 5 inside the tower body 1. During operation, the liquid pump 2 transports the scrubbing liquid at the bottom of the tower body 1 to the spray pipes 6 for spraying. A support plate 7 for supporting the packing is installed on the inner wall of the tower body 1 above the air inlet pipe 3. Since the exhaust gas and scrubbing liquid need to pass through the support plate 7, the support plate 7 is densely perforated, and the diameter of the perforations is smaller than that of the packing. A clamping assembly 8 is installed on the inner wall of the tower body 1 between the support plate 7 and the spray pipe 6 to clamp the packing. An adjustment mechanism 9 for adjusting the washing efficiency is also installed on one side of the tower body 1. A drive mechanism 10 is installed on the outer wall of the tower body 1 to drive the adjustment mechanism 9 to operate. A controller 11 is installed below the drive mechanism 10.

[0053] The adjusting mechanism 9 includes a slide groove 901, a connecting bar 905, a first pull rod 907, and a connecting plate 911. The slide groove 901 is horizontally opened on one side of the upper surface of the support plate 7. A base 902 is slidably connected inside the slide groove 901. A mounting frame 903 is connected to the upper end of the base 902. A rotating partition assembly 904 is installed inside the mounting frame 903. The connecting bar 905 passes through the clamping assembly 8 and is installed on the upper end of the mounting frame 903. A baffle 906 for preventing spray liquid splashing is connected to the upper end of the connecting bar 905. The upper end of the baffle 906 is slidably connected to the spray pipe 6 through a through hole. The first pull rod 907 is movably installed inside the slide groove 901 and connected to one end of the base 902. A second pull rod 908 is symmetrically fixed on one side of the baffle 906. A third pull rod 909 is movably installed inside the spray pipe 6. A piston 910 for sealing the spray pipe 6 is installed at the end of the third pull rod 909. The connecting plate 911 is movably installed on one side of the outer wall of the tower body 1. The first tie rod 907, the second tie rod 908 and the third tie rod 909 pass through the through hole on the tower body 1 and are connected to one side of the connecting plate 911.

[0054] like Figure 9 As shown, the connecting plate 911, the first pull rod 907, the second pull rod 908, the third pull rod 909, the base 902, the mounting frame 903, the connecting strip 905, and the baffle 906 are a connected whole.

[0055] During routine scrubbing of exhaust gas in this scrubbing tower, the exhaust gas enters the tower body 1 through the inlet pipe 3, then moves upward through the support plate 7, and moves upward by the mounting frame 903 and the rotating partition assembly 904, contacting the packing material wetted by the scrubbing liquid for washing. After washing, the gas moves upward through the compression assembly 8 and continues to move upward along the baffle 906 until it passes through the demister 5 and the exhaust pipe 4 and is discharged upward. The exhaust gas washing discharge channel is established by the mounting frame 903, the rotating partition assembly 904, and the baffle 906 combined with the inner wall of the tower body 1.

[0056] When adjustments to production capacity lead to an increase or decrease in the exhaust gas volume of the intake pipe 3, necessitating adjustments to the washing efficiency, the controller 11, upon receiving a signal, sequentially activates the clamping assembly 8, the rotating partition assembly 904, and the drive mechanism 10. The drive mechanism 10 drives the connecting plate 911 to move horizontally. Under the pull or push of the connecting plate 911, the first pull rod 907, the second pull rod 908, the third pull rod 909, and the base 902 drive the mounting frame 903, the rotating partition assembly 904, and the baffle 906 to move horizontally a certain distance within the slide groove 901. If the exhaust gas volume increases, the connecting plate 911 is driven to move away from the tower body 1, while simultaneously increasing the circulation power of the liquid pump 2. At this time, the exhaust gas washing discharge channel expands, allowing more packing material to flow into the left side of the rotating partition assembly 904 to participate in exhaust gas washing. Furthermore, the piston 910, moving with the third pull rod 909, enables more spray heads of the spray pipe 6 to release washing liquid, ensuring that the washing liquid is evenly dispersed on the packing material. Thus, the overall washing efficiency of the washing tower is improved.

[0057] If the exhaust gas volume decreases, the drive connecting plate 911 moves towards the tower body 1, and all the tie rods are inserted back into the tower body 1. At the same time, the circulation power of the liquid pump 2 is reduced. At this time, the exhaust gas washing and discharge channel narrows, some of the packing returns to the right side of the rotating partition assembly 904, the amount of packing involved in washing decreases, and the piston 910, along with the movement of the third tie rod 909, re-closes part of the spray head of the spray pipe 6. At this time, the overall washing efficiency of the washing tower is reduced, thereby meeting the washing requirements when the exhaust gas emission volume is reduced.

[0058] The washing efficiency of the scrubbing tower can be flexibly adjusted by adjusting the amount of packing material involved in the washing when the exhaust gas volume increases or decreases. This avoids situations where the waste gas volume is too small, resulting in waste of washing liquid, or the waste gas volume is too large, resulting in insufficient washing and forced production reduction. Furthermore, when adjusting the amount of packing material, the spray volume and spray area of ​​the washing liquid in the spray pipe 6 are also adjusted simultaneously to ensure that all packing material involved in the washing of exhaust gas can be effectively wetted, which better meets the flexible and ever-changing application needs of current enterprises.

[0059] The rotating partition assembly 904 includes a mounting shaft 9041, a wall groove 9043, a sliding sleeve 9045, a permanent magnet slider 9047, and an electromagnetic strip 9049. Two mounting shafts 9041 are symmetrically connected and rotate within the mounting frame 903. A flap 9042 is fixedly mounted on the mounting shaft 9041. The wall groove 9043 is formed on the inner wall of the tower body 1 on both sides of the mounting frame 903. A rotating pin 9044 is integrally formed at the end of the mounting shaft 9041, passing through the mounting frame 903, and is located within the wall groove 9043. The sliding sleeve 9045 is slidably connected to the upper end of the wall groove 9043, and the lower end of the sliding sleeve 9045 is connected to the frame wall of the mounting frame 903 through the wall groove 9043 via a synchronous bracket 9046. Figure 14 As shown, the permanent magnet slider 9047 is slidably connected inside the sliding sleeve 9045. The lower end of the permanent magnet slider 9047 is rotatably connected to the push rod 9048. The lower end of the push rod 9048 is rotatably connected to the rotating pin 9044. The push rod 9048 is kept slightly inclined in the wall groove 9043, which facilitates the push rod 9048 to move up and down along the inclined direction later.

[0060] When the mounting frame 903 moves horizontally, the sliding sleeve 9045 can be moved synchronously via the synchronous bracket 9046. The permanent magnet slider 9047 and push rod 9048 also move horizontally synchronously with the mounting shaft 9041 and rotating pin 9044. The electromagnetic strip 9049 is embedded in the housing of the tower body 1, located above the wall groove 9043, and is used to control the movement of the permanent magnet slider 9047. Figure 11 and Figure 12 As shown, there are a total of six grooves in the wall 9043, and there are also six electromagnetic strips 9049.

[0061] During the washing operation in the scrubbing tower, the flap 9042 isolates the packing area, so that the exhaust gas and washing liquid can only pass through one side of the flap 9042, ensuring the smooth progress of the washing.

[0062] When the drive mechanism 10 is about to move the connecting plate 911 and the mounting frame 903 horizontally to adjust the washing efficiency, the controller 11 first controls the electromagnetic strip 9049 to be energized. After the electromagnetic strip 9049 is energized, it generates sufficient repulsive force on the permanent magnet slider 9047, pushing the permanent magnet slider 9047 and the push rod 9048 to slide downward along the sliding sleeve 9045 for a certain distance. The push rod 9048 then drives the mounting shaft 9041 and the flip plate 9042 to rotate within the mounting frame 903 through the rotating pin 9044. By controlling the downward stroke of the sliding sleeve 9045, the mounting shaft 9041 and the flip plate 9042 are ensured to rotate 90 degrees, ultimately making the flip plate 9042 perpendicular to the mounting frame 903. Since the filler is granular and in a moving state, the filler on both sides of the plate will rotate synchronously when the flip plate 9042 rotates, ensuring the continuity of the rotational movement of the flip plate 9042 and preventing interference. At this time, the connecting plate 911 will not be subject to significant resistance from the filler when moving the mounting frame 903 horizontally. After the movement is completed, the controller 11 controls the change of the current direction of the electromagnetic bar 9049 to generate an attraction force on the permanent magnet slider 9047. The permanent magnet slider 9047 then drives the flap 9042 to rotate and reset through the push rod 9048, and the filling area is separated again.

[0063] By rotating the partition assembly 904, the angle of the flap 9042 can be quickly adjusted. When the exhaust gas discharge changes and the washing efficiency of the scrubbing tower needs to be adjusted, the flap 9042 is made perpendicular to the mounting frame 903, ensuring that the mounting frame 903 can move smoothly horizontally within the packing area and significantly reducing the resistance during the movement. After the adjustment is completed, the flap 9042 is rotated back to isolate the two sides of the packing area, ensuring the smooth progress of the washing operation.

[0064] The clamping assembly 8 includes a top plate 801, a lifting groove 803, a buffer rod 807, and a permanent magnet strip 808. The top plate 801 is installed on the inner wall of the tower body 1, and several inner sleeves 802 are formed through the lower end face of the top plate 801. The lifting groove 803 is located on the inner wall of the tower body 1 below the top plate 801, and a bottom plate 804 is movably installed in the lifting groove 803, sliding up and down within the lifting groove 803. Several outer sleeves 805, matching the inner sleeves 802, are formed through the upper end face of the bottom plate 804, and the outer sleeves 805 are fitted onto the outside of the inner sleeves 802. Both the top plate 801 and the bottom plate 804 have through grooves 806 on one side for the horizontal sliding of the connecting strip 905. A buffer rod 807 is installed at the upper end of the lifting groove 803 and connected to the base plate 804. The buffer rod 807 is a hydraulic rod used to slow down the descent speed of the base plate 804, ensuring that the base plate 804 only descends to its final position after the flip plate 9042 has rotated. Permanent magnet strips 808 are embedded and installed around the outer edge of the base plate 804, matching the electromagnetic strips 9049. The electromagnetic strips 9049 are rectangularly distributed below the lifting groove 803.

[0065] When the rotating partition assembly 904 operates, i.e., when the flap 9042 rotates, the permanent magnet strip 808 is also repelled by the energization of the electromagnetic strip 9049, thus driving the base plate 804 upward along the lifting groove 803. During the upward movement of the base plate 804, the inner sleeve 802 retracts into the outer sleeve 805 to ensure that the movement is not interfered with. Due to the upward movement of the base plate 804, a gap appears above the packing area, and the packing is in a free state, at which time the rotational resistance of the flap 9042 is reduced. During the horizontal movement of the mounting frame 903 and the flap 9042, the base plate 804 also remains in an upward state, reducing the movement resistance. After the mounting frame 903 and the flap 9042 have completed their movement, the current direction of the electromagnetic strip 9049 changes, and the base plate 804 slowly resets under the action of the buffer rod 807, returning to above the packing.

[0066] By using the clamping component 8, the space above the filler can be flexibly controlled and quickly adjusted, significantly reducing the resistance encountered by the flip plate 9042 during rotation and horizontal movement, improving movement efficiency, and the bottom plate 804 can automatically reset after adjustment, ensuring the clamping effect of the filler during subsequent washing. Furthermore, the entire lifting and lowering of the bottom plate 804 is accomplished by the magnetic force of the electromagnetic strip 9049, which is the same as the rotation power source of the flip plate 9042. There is no additional power input, avoiding equipment redundancy and ensuring the synchronization of the two movements.

[0067] The drive mechanism 10 includes a mounting cover 1001 and a ball screw 1003. The mounting cover 1001 is fixedly mounted on the outer wall of the tower body 1, located outside the connecting plate 911. A motor 1002 is mounted on one end of the mounting cover 1001. One end of the ball screw 1003 is connected to the output end of the motor 1002, and the other end of the ball screw 1003 is rotatably connected to the outer wall of the tower body 1. The nut on the ball screw 1003 is installed in the mounting hole on the connecting plate 911.

[0068] When it is necessary to drive the connecting plate 911 to move horizontally, the motor 1002 is started. The motor 1002 drives the ball screw 1003 to rotate, thereby driving the connecting plate 911 to move horizontally. The direction of rotation of the motor 1002 determines the direction of movement of the connecting plate 911.

[0069] A gas detector 12 is installed at the upper end of the tower body 1, and a controller 11 is fixedly installed on the lower side of the mounting cover 1001. The controller 11 is electrically connected to the liquid pump 2, the electromagnetic strip 9049, the motor 1002, and the gas detector 12 via wires. The gas detector 12 can detect the washing effect and exhaust volume of the waste gas and transmit the data to the controller 11. The controller 11 then determines the required washing efficiency and issues adjustment commands to the liquid pump 2, the electromagnetic strip 9049, and the motor 1002.

[0070] The width of the chute 901 and the through chute 806, as well as the diameter of the inner sleeve 802 and the outer sleeve 805, are all smaller than the diameter of the packing material to prevent the packing material from getting stuck in the chute 901 and affecting the adjustment, or from leaking out through the through chute 806 and the sleeve.

[0071] The upper and lower ends of the sliding sleeve 9045 are fixedly equipped with limiting rings to limit the stroke of the permanent magnet slider 9047. The limiting rings ensure that the push rod 9048 can only drive the mounting shaft 9041 to rotate 90 degrees.

[0072] The lower end of the base 902 is rotatably connected to several steel balls through ball grooves to reduce friction and ensure smooth sliding of the base 902.

[0073] Working Principle: When the gas detector 12 sends the detection data to the controller 11 to determine if the efficiency of the scrubbing tower needs to be adjusted, the controller 11 first energizes the electromagnetic bar 9049. After being energized, the electromagnetic bar 9049 generates a repulsive force on the permanent magnet bar 808, causing the base plate 804 to move upward along the lifting groove 803, creating a gap above the packing area, allowing the packing to be in a free state. Simultaneously, the electromagnetic bar 9049 also generates sufficient repulsive force on the permanent magnet slider 9047, pushing the permanent magnet slider 9047 and the push rod 9048 downward along the sliding sleeve 9045 by a certain distance. The push rod 9048 then drives the mounting shaft 9041 and the flap 9042 to rotate within the mounting frame 903 via the rotating pin 9044. By controlling the downward stroke of the sliding sleeve 9045, the mounting shaft 9041 and the flap 9042 are ensured to rotate 90 degrees, ultimately making the flap 9042 perpendicular to the mounting frame 903. At this time, the controller 11 controls the start motor 1002, which drives the ball screw 1003 to rotate and drives the connecting plate 911 to move horizontally. Under the pull or push of the connecting plate 911, the first pull rod 907, the second pull rod 908, the third pull rod 909, and the base 902 drive the mounting frame 903, the flip plate 9042, and the baffle 906 to move horizontally a certain distance within the slide groove 901. The controller 11 sets the rotation direction and number of revolutions of the output end according to the difference between the current detection data and the target data, thereby achieving precise control of the moving distance. After the mounting frame 903, the flap 9042, and the baffle 906 move to the target position, the motor 1002 is turned off. The controller 11 controls the change of the current direction on the electromagnetic strip 9049. The electromagnetic strip 9049 generates an attractive force on both the permanent magnet slider 9047 and the permanent magnet strip 808. The permanent magnet slider 9047 then drives the flap 9042 to rotate and reset via the push rod 9048. The bottom plate 804 also slowly resets under the action of the buffer rod 807, returning to above the packing. At this point, the efficiency adjustment of the scrubbing tower is complete.
