Description

Technical Field

[0001] This utility model relates to the field of fiberglass absorption tower technology, specifically to fiberglass absorption towers. Background Technology

[0002] Fiberglass reinforced plastic (FRP) absorption towers typically refer to absorption towers made of fiberglass reinforced plastic (FRP). These towers are commonly used in industrial gas purification systems, particularly for removing pollutants from waste gases such as hydrogen sulfide, ammonia, and benzene. FRP offers advantages such as corrosion resistance, high-temperature resistance, lightweight construction, and long service life, making it widely used in chemical and environmental protection fields. Current methods often involve installing a spray solution inside the absorption tower that reacts with the pollutants in the waste gas. The spraying action of the solution enhances the reaction with the waste gas.

[0003] In existing technologies, the spray liquid that reacts with the waste gas is recycled to reduce treatment costs. However, the following technical problems still exist: when toxic gases in the waste gas react with the spray liquid, sediments are released. As these sediments flow downward with the spray liquid, they clog the filter components on the lower side, thereby reducing the circulation of the spray liquid. This requires workers to frequently replace and maintain the filter components, reducing the practicality of the device. Utility Model Content

[0004] This invention proposes a fiberglass absorption tower that improves the reaction effect between waste gas and spray liquid, reduces the clogging of filter components by waste materials, increases the circulation of spray liquid, enables better recycling of spray liquid, and reduces waste gas treatment costs.

[0005] The technical solution of this utility model is as follows:

[0006] A fiberglass reinforced plastic (FRP) absorption tower includes a FRP tower body, a spray device, a water supply pipe for circulating water within the FRP tower body, packing material for enhancing the reaction effect between the spray liquid and the waste gas, and a water supply pump for driving the water supply pipe. The spray device is fixedly connected to the top of the inner wall of the FRP tower body. The upper end of the water supply pipe is connected to the spray device, and the lower end of the water supply pipe is connected to the bottom wall of the FRP tower body. The packing material is fixedly connected within the FRP tower body and is located below the spray device.

[0007] An air inlet pipe is fixedly connected to the outside of the fiberglass tower body to input the waste gas to be treated into the fiberglass tower body. An air outlet pipe is fixedly connected to the air inlet pipe to output the treated waste gas from the fiberglass tower body. A vibrating filter assembly is connected between the lower end of the air inlet pipe and the water supply pipe to filter the spray liquid after the waste gas is treated.

[0008] Furthermore, the oscillating filter assembly includes a first limiting plate and a second limiting plate. Both the first limiting plate and the second limiting plate are fixedly connected to the inner wall of the fiberglass tower body. A half-hollow drainage cylinder is rotatably connected between the first limiting plate and the second limiting plate. A drive motor is fixedly connected to the upper side of the first limiting plate. The drive shaft of the drive motor is fixedly connected to the drainage cylinder. A filter block for filtering the deposited wastewater is slidably connected to the drainage cylinder. A reset assembly is connected to the lower side of the filter block to reset the filter block after it moves.

[0009] The drain cylinder has a first spiral plate and a second spiral plate arranged in opposite spiral directions. A first transmission column is fixedly connected to the filter block. The first transmission column abuts against the first spiral plate. A stirring fan is snapped into the lower end of the drain cylinder. A water lifting plate is rotatably connected to the stirring fan. A second transmission column is fixedly connected to the lower end of the water lifting plate. The second transmission column abuts against the surface of the second spiral plate.

[0010] Furthermore, the reset assembly includes a reset column, which is slidably connected to the filter block. A limit plate is fixedly connected to the lower end of the reset column, and the limit plate is slidably connected to the drain cylinder. A reset spring is sleeved on the reset column, and the two ends of the reset spring abut against the filter block and the limit plate, respectively.

[0011] Furthermore, a filter screen is fixedly connected to the filter block, and several return grooves are opened on the inner wall of the filter block. Several drainage grooves are opened on the drainage cylinder, and each drainage groove is connected to the hollow part inside the drainage cylinder.

[0012] Furthermore, a plurality of first limiting posts are fixedly connected to the filter block, and each of the first limiting posts is slidably connected to a first limiting plate. A plurality of second limiting posts are fixedly connected to the lower side of the water lifting plate, and each of the second limiting posts is slidably connected to a second limiting plate.

[0013] Furthermore, a linkage cylinder is fixedly connected to the lower end of the drain cylinder, and a plurality of locking grooves are circumferentially formed on the linkage cylinder with the axis of the linkage cylinder as the center. A plurality of locking blocks are fixedly connected to the inner wall of the stirring fan with the axis of the stirring fan as the center. The number of locking blocks is the same as the number of locking grooves and they are correspondingly arranged.

[0014] Furthermore, the width of the upper opening of the snap-fit ​​groove is greater than the width of the lower groove.

[0015] The beneficial effects of this utility model are as follows:

[0016] The vibrating filter assembly can guide the exhaust gas through vibration, allowing it to react better with the spray-impregnated packing material, thus improving the reaction efficiency. Simultaneously, the vibration causes the exhaust gas inside the fiberglass tower to collide and vibrate with the exhaust gas just entering from the inlet pipe. This allows large particles in the exhaust gas to settle better with the downward-flowing spray liquid, and also improves the filtration of the spray liquid containing impurities. This reduces the clogging of the filter blocks by waste materials, increases the circulation of the spray liquid, and enables better recycling of the spray liquid, thereby reducing the cost of exhaust gas treatment.

Detailed Implementation

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0027] like Figures 1 to 7 As shown, this embodiment proposes a fiberglass absorption tower, including a fiberglass tower body 11, a spray device 12, a water supply pipe 13 for circulating water in the fiberglass tower body 11, a packing material 14 for increasing the reaction effect between the spray liquid and the waste gas, and a water supply pump 15 for driving the water supply pipe 13. The spray device 12 is fixedly connected to the top of the inner wall of the fiberglass tower body 11. The upper end of the water supply pipe 13 is connected to the spray device 12. The spray device 12 sprays the spray liquid onto the packing material 14, so that the waste gas can react through the packing material 14, increasing the reaction time and allowing the toxic gases in the waste gas to fully react with the spray liquid, thereby improving the waste gas treatment effect. The lower end of the water supply pipe 13 is connected to the bottom wall of the fiberglass tower body 11. The packing material 14 is fixedly connected in the fiberglass tower body 11 and is located below the spray device 12.

[0028] The exhaust gas to be treated is input into the air inlet pipe 21 of the FRP tower body 11 and fixedly connected to the outside of the FRP tower body 11. The exhaust pipe 22, which outputs the treated exhaust gas from the FRP tower body 11, is fixedly connected to the air inlet pipe 21. The vibrating filter assembly 3, which filters the spray liquid after exhaust gas treatment, is connected between the air inlet pipe 21 and the lower end of the water supply pipe 13. The vibrating filter assembly 3 can vibrate and guide the exhaust gas, so that the exhaust gas can better react with the packing material 14 impregnated with the spray liquid, thereby improving the reaction effect between the exhaust gas and the spray liquid. At the same time, it can also vibrate the exhaust gas, so that the exhaust gas in the FRP tower body 11 collides and vibrates with the exhaust gas just input from the air inlet pipe 21. This allows large particles in the exhaust gas to settle better with the downward flowing spray liquid, and can better filter the sedimented spray liquid with impurities, reducing the clogging effect of waste on the filter block 33, increasing the circulation of the spray liquid, and enabling better recycling of the spray liquid, thereby reducing the cost of exhaust gas treatment.

[0029] like Figures 2-5As shown, the oscillating filter assembly 3 includes a first limiting plate 31 and a second limiting plate 32. Both the first limiting plate 31 and the second limiting plate 32 are fixedly connected to the inner wall of the fiberglass tower body 11. The half-hole hollow drainage cylinder 35 is rotatably connected between the first limiting plate 31 and the second limiting plate 32 to ensure that the axis of the drainage cylinder 35 will not deviate during rotation. Thus, the drainage cylinder 35 can drive each component to work for a longer time. The drive motor 310 is fixedly connected to the upper side of the first limiting plate 31. The drive shaft of the drive motor 310 is fixedly connected to the drainage cylinder 35. The filter block 33, which filters the deposited wastewater, is slidably connected to the drainage cylinder 35. The drive motor 310 ensures that the drainage cylinder 35 rotates stably. The reset assembly, which resets the filter block 33 after it moves, is connected to the lower side of the filter block 33. The reset assembly can ensure that the filter block 33 can move up and down stably through the rotation of the drainage cylinder 35.

[0030] The first spiral plate 351 and the second spiral plate 352 are arranged on the drain cylinder 35 with opposite spiral directions. During normal rotation of the drain cylinder 35, the first transmission column 361 and the second transmission column 362, which respectively cooperate with the first spiral plate 351 and the second spiral plate 352, move in opposite directions. The first transmission column 361 is fixedly connected to the filter block 33 and abuts against the first spiral plate 351. The stirring fan 38 is engaged with the lower end of the drain cylinder 35, allowing the stirring fan 38 to rotate with the drain cylinder 35. The airflow guides the exhaust gas, allowing it to react better with the spray liquid inside the fiberglass tower body 11. Simultaneously, the stirring fan 38 can disengage from the rotation of the drain cylinder 35, enabling the airflow to operate intermittently and generating an oscillating effect, further enhancing the reaction between the exhaust gas and the spray liquid. The stirring fan 38 is rotatably connected to the water-lifting plate 39, and the second transmission column 362 is fixedly connected to the lower end of the water-lifting plate 39, with the second transmission column 362 abutting against the surface of the second spiral plate 352.

[0031] like Figures 2-5 As shown, the reset assembly includes a reset column 41, which is slidably connected to the filter block 33. A limiting plate 43 is fixedly connected to the lower end of the reset column 41 and is slidably connected to the drain cylinder 35. A bearing component can be provided between the limiting plate 43 and the drain cylinder 35 to keep the height of the limiting plate 43 on the drain cylinder 35 constant and to keep them in a relative rotational state. A reset spring 42 is sleeved on the reset column 41, and the two ends of the reset spring 42 abut against the filter block 33 and the limiting plate 43, respectively. When the first spiral plate 351 moves the filter block 33 downward through the rotation of the drain cylinder 35, the first transmission column 361 can always abut against the surface of the first spiral plate 351 under the action of the reset spring 42, so that the filter block 33 can continuously move up and down.

[0032] At the same time, when the first drive column 361 moves to the fault point of the first spiral plate 351, that is, the lowest point, the first drive column 361 will carry the filter block 33 from the lowest point to the highest point in an instant, thereby generating a vibration effect. This vibration effect can shake the particles attached to the filter block 33, prevent too many particles from adhering to the surface of the filter block 33, and ensure the flow effect of wastewater through the filter block 33.

[0033] like Figures 2-5 As shown, the filter screen 37 is fixedly connected to the filter block 33. When the filter block 33 moves downward, the sedimented water can flow into the filter block 33 through the filter screen 37. The filter screen 37 filters the particulate matter in the wastewater. Several return water channels 331 are opened on the inner wall of the filter block 33, and several drain channels 353 are opened on the drain cylinder 35. Each drain channel 353 is connected to the hollow part inside the drain cylinder 35. When the filter block 33 moves to the highest point, the filter block 33 will block the drain channel 353. When the filter block 33 moves downward, the area of ​​the drain channel 353 connected to the return water channel 331 will continuously expand, thereby ensuring that the sedimented water entering the filter block 33 can flow downward through the hollow part inside the drain cylinder 35 more quickly, so that the water supply pipe 13 can recycle this part of the filtered spray liquid.

[0034] like Figure 2 ~ and Figure 3 As shown, several first limiting posts 341 are fixedly connected to the filter block 33, and each first limiting post 341 is slidably connected to the first limiting plate 31. Several second limiting posts 342 are fixedly connected to the lower side of the lifting plate 39, and each second limiting post 342 is slidably connected to the second limiting plate 32. This allows the filter block 33 and the lifting plate 39 to move stably up and down without changing direction, reducing wear between components and increasing the service life of the components.

[0035] like Figure 6 and Figure 7 As shown, the linkage cylinder 354 is fixedly connected to the lower end of the drain cylinder 35. Several locking slots 355 are arranged in a ring around the axis of the linkage cylinder 354. Several locking blocks 381 are fixedly connected in a ring around the axis of the stirring fan 38 on the inner wall of the stirring fan 38. The number of locking blocks 381 and locking slots 355 are the same and correspondingly arranged, so that the drain cylinder 35 can rotate after the locking blocks 381 are locked with the locking slots 355. Then, when the water lifting plate 39 moves up, the locking blocks 381 will disengage from the locking slots 355, thereby stopping the rotation of the stirring fan 38. This facilitates the flow of water on the water lifting plate 39 through the filter block 33. The intermittent rotation increases the oscillation effect of the stirring fan 38 on the airflow inside the fiberglass tower body 11, thereby increasing the reaction effect between the waste gas and the spray liquid inside the fiberglass tower body 11, that is, improving the waste gas treatment effect.

[0036] like Figure 6 and Figure 7 As shown, the width of the upper opening of the snap-fit ​​groove 355 is greater than the width of the lower opening, so that when the stirring fan 38 moves down along the linkage cylinder 354, the snap-fit ​​block 381 can be more easily snapped into the snap-fit ​​groove 355. This allows the rotation of the drain cylinder 35 to drive the stirring fan 38 to rotate. The rotation of the stirring fan 38 can stir the water accumulated on the upper side of the water lifting plate 39, preventing excessive sediment from settling.

[0037] The principle of this embodiment is as follows:

[0038] The drive motor 310 drives the drain cylinder 35 to rotate continuously, which in turn drives the first spiral plate 351 and the second spiral plate 352 to rotate synchronously in the up and down spiral direction.

[0039] When the first spiral plate 351 rotates, the first transmission column 361, which abuts against the lower side of the first spiral plate 351, moves the filter block 33 downward. When the first transmission column 361 moves to the position where the upper and lower ends of the first spiral plate 351 are discontinuous, under the action of the reset component, it will move the filter block 33 from the lowest point to the highest point. This will generate a vibration effect, which can shake off the impurities adsorbed on the lower side of the filter block 33, so that the spray liquid can flow better. When the filter block 33 moves downward, the return water tank 331 and the drain tank 353 will be connected. That is to say, when the filter block 33 squeezes the spray liquid with sediment downward, the connected slot will be exposed, so that the spray liquid can flow out quickly from the drain tank 353 by its own weight.

[0040] When the second spiral plate 352 rotates, the second transmission column 362, which abuts against the upper side of the second spiral plate 352, moves the water lifting plate 39 upward. When the second transmission column 362 moves to the fault position at the upper and lower ends of the second spiral plate 352, it will slide the water lifting plate 39 from the highest point to the lowest point under its own gravity. The upward movement of the water lifting plate 39 raises the water level of the sedimented spray liquid, allowing more spray liquid to flow out through the filter block 33.

[0041] When the lifting plate 39 moves upward, it also moves the stirring fan 38 upward, causing the stirring fan 38 to disengage from the linkage cylinder 354. Without the drive of the linkage cylinder 354, the rotation speed of the stirring fan 38 decreases, reducing the airflow guidance effect within the fiberglass tower body 11. This causes the new waste gas introduced from the air inlet pipe 21 to collide with the waste gas already in the fiberglass tower body 11. Then, the lifting plate 39 moves downward, causing the stirring fan 38 to reset, allowing the stirring fan 38 to continue rotating in conjunction with the linkage cylinder 354. This results in an intermittent airflow guidance effect within the fiberglass tower body 11, allowing the waste gas to collide with each other, increasing the reaction time between the waste gas and the spray liquid, and thus improving the treatment effect of the absorption tower on the waste gas.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
