Description

Technical Field

[0001] This utility model relates to the field of acid mist recovery technology, specifically to an acid mist recovery device for an acid mist purification tower. Background Technology

[0002] In industrial production processes, such as metallurgy, electroplating, chemical processing, and electronic component manufacturing, a large amount of acidic gases are emitted. These acidic gases combine with water vapor in the air to form acid mist. Acid mist is not only highly corrosive, causing damage to production equipment and factory buildings and shortening equipment lifespan, but it also spreads to the surrounding environment, polluting the atmosphere, soil, and water bodies, and endangering the balance of the ecosystem. Therefore, devices for acid mist recovery have emerged.

[0003] Patent CN219462986U discloses an acid mist recovery device for an acid mist purification tower, including a base, an acid mist tower on top of the base, an acid mist tower top on top of the acid mist tower, a mist inlet pipe on top of the mist tower top, a liquid inlet pipe around the outer ring of the acid mist tower, and an installation groove on top of the acid mist tower. This acid mist recovery device for an acid mist purification tower injects the required chemical solution for removing acid mist into the acid mist tower through the liquid inlet pipe, ensuring the liquid level is higher than the top mist outlet. Then, the acid mist outlet pipe is directly connected to the mist inlet pipe, allowing the acid mist to be guided through a guide pipe inside the top of the acid mist tower and then through a second mist inlet pipe into the main mist inlet pipe within the installation groove. Finally, the mist inlet branch pipes within the groove guide the acid mist directly into the interior of the chemical solution from the mist outlet, ensuring thorough mixing of the acid mist and the chemical solution, thus achieving the purpose of acid mist recovery and solving the problem of low recovery efficiency in existing acid mist recovery devices.

[0004] However, the above technical solutions still have the following shortcomings: When the gas is discharged into the acid mist tower, in addition to acid mist and other substances, the gas also contains other solid particulate impurities. This method cannot filter the solid impurities in the initially discharged gas. When the solid impurities enter the drug solution that adsorbs acid mist along with the gas, it will cause too many impurities inside the drug solution, affecting the subsequent acid mist extraction. Moreover, too many impurities will reduce the performance of the drug solution and increase material loss.

[0005] Therefore, an acid mist recovery device for acid mist purification towers is proposed to solve the problems mentioned above. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] Please see Figure 1 - Figure 6 An acid mist recovery device for an acid mist purification tower in this embodiment includes a purification tower body 1. A pull-out box 2 is provided inside the purification tower body 1. One side of the pull-out box 2 penetrates the purification tower body 1. The pull-out box 2 is slidably connected to the purification tower body 1. Several filter plates 3 are fixedly connected to the inner wall of the pull-out box 2. The filter plates 3 are arranged in a straight line. The purification tower body 1 is provided with a filtration mechanism through the filter plates 3. An air outlet 14 is opened at the top of the purification tower body 1. An emission component is provided through the air outlet 14 of the purification tower body 1. The filtration mechanism includes several filter holes 4 opened on the surface of the filter plate 3, an air inlet 5 is opened on the side of the purification tower body 1, a baffle plate 6 is provided on the side of the pull box 2, and a slot 7 is opened on the side of the baffle plate 6. The emission assembly includes a baffle plate 15 disposed on the top of the purification tower body 1, a baffle plate 16 disposed on the top of the purification tower body 1, and a motor 17 for driving disposed above the baffle plate 16. In the process of collecting acid mist, the gas is first discharged through the air inlet 5. At this time, the acid mist will enter the pull-out housing 2. The air inlet 5 is located below the bottom filter plate 3. For details, please refer to [link to relevant documentation]. Figure 3 At this point, the gas will accumulate inside the pulling box 2 and gradually move upwards. Continue to observe... Figure 3 The gas gradually moves upwards through the filter holes 4 on the bottom filter plate 3. Since the radius of the filter holes 4 decreases as they rise, impurities in the gas are filtered repeatedly and retained within the pulling chamber 2. Finally, the gas enters the cavity between the pulling chamber 2 and the water storage tank 12. At this point, the air pump 13 can be activated to deliver the filtered gas (containing solid impurities) to the water storage tank 12. The liquid stored in the water storage tank 12 is used to adsorb acid mist. The acid mist is adsorbed and collected within the water storage tank 12. Afterwards, the electric... Machine 17, through the discharge mechanism, will quantitatively discharge the gas in the water storage tank 12 after the acid mist has been adsorbed. Since the adsorption of acid mist takes time, the quantitative discharge of gas through the discharge mechanism will help the liquid in the water storage tank 12 to more fully absorb the acid mist. When it is necessary to clean the impurities in the pull box 2, the pull box 2 is pulled out from the purification tower body 1. Then, the baffle plate 6 is pulled up. Through the filtration mechanism, the baffle plate 6 will leave the pull box 2. At this time, the filter holes 4 on the filter plate 3 can be processed. At this point, the gas before acid mist extraction is filtered to remove solid impurities, reducing the likelihood of solid impurities entering the acid mist absorption solution along with the gas. Subsequent extraction of acid mist from the solution will not be hindered by solid impurities, making extraction easier. Furthermore, reducing the amount of solid impurities entering the solution ensures its purity, preventing dilution or damage to internal molecules, thus improving the absorption efficiency of the solution and reducing material waste.

[0020] The filtration mechanism also includes a limiting block 8 set inside the slot 7, a spring 9 set inside the slot 7, a slot 10 opened on the inner wall of the pull box 2, a limiting block 11 set inside the slot 10, a water storage tank 12 set inside the purification tower body 1, an air pump 13 set on the side of the purification tower body 1, and filter holes 4 on several filter plates 3 with different cross-sectional radii, the cross-sectional radius of the filter holes 4 located at the bottom is larger than the cross-sectional radius of the filter holes 4 located at the top. The air inlet 5 is connected to the side of the pull box 2. The air inlet 5 is located below the filter plate 3. The first baffle plate 6 is slidably connected to the pull box 2. The first baffle plate 6 is adapted to the pull box 2. The first limiting block 8 is slidably connected to the first slot 7. One end of the spring 9 is fixedly connected to the inner wall of the first slot 7. The other end of the spring 9 is fixedly connected to one end of the first limiting block 8. The second limiting block 11 is fixedly connected to the inner wall of the second slot 10. The other end of the limiting block 8 extends into the slot 10. The limiting block 8 and the slot 10 are slidably connected. The limiting block 11 is located above the limiting block 8. The side of the limiting block 11 that contacts the limiting block 8 is an arc surface. The side of the limiting block 8 that contacts the limiting block 11 is an arc surface. The limiting block 8 and the limiting block 11 are compatible. The water storage tank 12 is fixedly connected to the inner wall of the purification tower body 1. The water storage tank 12 is located above the pulling box 2. The suction end of the air pump 13 is connected to the purification tower body 1. The suction end of the air pump 13 is located between the pulling box 2 and the water storage tank 12. The air delivery end of the air pump 13 is connected to the purification tower body 1. The air delivery end of the air pump 13 is connected to the side of the water storage tank 12. Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 When the gas is discharged, it is first discharged into the purification tower body 1 through the air inlet 5. Then, the gas continues to reach the interior of the pull box 2 through the air inlet 5. At this time, the gas is located below the filter plate 3, specifically below the bottom filter plate 3. Then, the gas begins to gather and gradually passes through the filter hole 4 to the next filter plate 3. At this time, some larger solid impurities will be filtered by the filter hole 4. Then, the gas gradually moves upward, and the impurities will be filtered by the increasingly smaller filter holes 4. Finally, the solid impurities will be filtered into the pull box 2. At this time, the gas reaches between the pull box 2 and the water storage tank 12. At this time, the air pump 13 can be started. The air pump 13 will draw the gas after filtering the solid impurities from between the water storage tank 12 and the pull box 2 and discharge the gas into the water storage tank 12. At this time, the gas will mix with the medicine in the water storage tank 12. The acid mist in the gas will be absorbed, and the remaining gas will continue to move upward and gather above the water storage tank 12. When cleaning solid impurities inside the pull box 2, pull the pull box 2 out of the purification tower body 1. Then, pull the baffle plate 6 upwards. As the baffle plate 6 moves upwards, the limiting block 8 and the limiting block 11 will come into contact. As the limiting block 8 gradually moves upwards, under the squeezing action of the limiting block 11, the limiting block 8 will gradually move away from the limiting block 11 and retract into the slot 7. At this time, as the limiting block 8 gradually moves, the spring 9 will gradually be in a compressed state. After the limiting block 8 is completely retracted into the slot 7, the baffle plate 6 can be removed from the pull box 2. At this time, with the baffle plate 6 removed, the sides of the filter plates 3 will not be blocked, and multiple filter plates 3 can be cleaned. When installing the baffle plate 6, press the limiting block. When the limiting block 8 is inserted into the slot 7, the spring 9 will be in a compressed state as the limiting block 8 gradually moves. Then, the baffle plate 6 is aligned with the pull box 2 and inserted. After the slot 7 is engaged with the inner wall of the pull box 2, the limiting block 8 is released. At this time, the spring 9 loses its compressive force and will start to drive the limiting block 8 to reset, so that the limiting block 8 always presses against the inner wall of the pull box 2. At this time, as the baffle plate 6 continues to move downward, when the bottom of the baffle plate 6 reaches the inner bottom wall of the pull box 2, the limiting block 8 is facing the slot 10. Under the reset action of the spring 9, the limiting block 8 will be engaged in the slot 10, fixing the position between the baffle plate 6 and the pull box 2. When there is no force to pull the baffle plate 6 upward, the baffle plate 6 and the pull box 2 will always be in a fixed state. At this point, the gas for which acid mist needs to be collected is filtered to remove solid impurities, and the filtration device can be easily cleaned without complicated procedures, improving cleaning efficiency and allowing the device to be put into operation as soon as possible, thus improving the device's working efficiency.

[0021] The emission assembly also includes a rotating shaft 18 located below the motor 17, an eccentric wheel 19 located below the baffle 16, a connecting rod 20 located at the bottom of the eccentric wheel 19, a connecting rod 21 located at the other end of the connecting rod 20, a guide rail 22 located at the top of the purification tower body 1, a moving rod 23 located inside the guide rail 22, a baffle 2 15 adapted to the air outlet 14, and the bottom of the baffle 16 fixedly connected to the top of the purification tower body 1. The bottom of the rotating shaft 18 passes through the top of the baffle 16. The rotating shaft 18 is rotatably connected to the baffle 16. The top of the baffle 16 is fixedly connected to the output end of the motor 17. The bottom of the baffle 16 is fixedly connected to the top of the eccentric wheel 19. The bottom of the eccentric wheel 19 is hinged to one end of the connecting rod 20. The other end of connecting rod 1 20 is hinged to one end of connecting rod 21, and the other end of connecting rod 21 is fixedly connected to the side of shield 2 15. The bottom of guide rail 22 is fixedly connected to the top of purification tower body 1. Moving rod 23 is slidably connected to guide rail 22, and one end of moving rod 23 is fixedly connected to the side of shield 2 15. Please refer to Figure 1 , Figure 2 and Figure 5 When the gas accumulated in the water storage tank 12 is discharged, the liquid in the water storage tank 12 will absorb the acid mist. After the acid mist is absorbed, the remaining gas will accumulate above the water storage tank 12, that is, at the inner top wall of the purification tower body 1. At this time, the starting motor 17 will drive the rotating shaft 18 to rotate on the baffle 16. At this time, as the rotating shaft 18 rotates, the eccentric wheel 19 will also rotate. Since the eccentric wheel 19 and the rotating shaft 18 are not concentric, that is, the eccentric wheel 19 rotates with an amplitude. As the eccentric wheel 19 rotates, the eccentric wheel 19 and the connecting rod... The angle between 20 and 21 will change. Under the limiting action of the guide rail 22 on the moving rod 23, the baffle plate 25 will move back and forth along the route of the guide rail 22. At this time, the movement of the baffle plate 25 will expose the vent 14, and the gas will be discharged. When the baffle plate 25 returns, it will block the vent 14 to prevent the gas from being discharged, thus completing the quantitative venting. The advantage of quantitative venting is that it provides more time for the absorption of acid mist and medicine in the water tank 12, making the absorption effect better. At this time, the gas that has absorbed the acid mist is discharged from the purification tower body 1, and the quantitative discharge helps the liquid in the water storage tank 12 to absorb the acid mist and improves the working efficiency of the device.

[0022] The installation method, connection method, or setting method disclosed in this embodiment are all common mechanical connections. Any connection method that can achieve its beneficial effect can be implemented, so the specific structural composition and working principle will not be described in detail in this embodiment.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
