Description

Technical Field

[0001] This utility model relates to the field of scrubbing towers, and in particular to a waste gas scrubbing tower with an anti-clogging structure. Background Technology

[0002] A scrubbing tower is a new type of gas purification equipment, widely used in pretreatment for industrial waste gas purification and dust removal. It is an improvement on the floating packing layer gas purifier, and is named a scrubbing tower because its working principle is similar to a washing process.

[0003] According to the search, for example, the anti-clogging exhaust gas scrubbing device disclosed in patent publication number CN219984244U and the anti-clogging exhaust gas scrubbing tower disclosed in publication number CN221999306U both cause the packing material stacked on the support to roll and misalign with each other, and use the friction of adjacent packing material to remove the surface deposits, thus achieving self-cleaning.

[0004] However, based on the above search and combined with existing technology, it was found that when the internal packing of the anti-clogging exhaust gas scrubbing tower disclosed above is subjected to vibration, the gaps between the packing become larger, which causes some impurities to escape upward with the gas through the gaps, resulting in a deterioration in the exhaust gas purification effect. Utility Model Content

[0005] The core of this invention lies in solving the problem in existing technologies where some impurities escape upwards with the gas through the enlarged gaps between the packing materials by using multiple supporting mesh disks in conjunction with a vibration component. Simultaneously, the friction between adjacent packing materials removes surface deposits, achieving self-cleaning.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A waste gas scrubbing tower with an anti-clogging structure includes a scrubbing tower body with an outlet and an inlet at the top and bottom ends, respectively. The scrubbing tower body is filled with packing material. Multiple support mesh trays are distributed at equal intervals from top to bottom on the inner side of the scrubbing tower body. The packing material is evenly stacked on the upper surface of the multiple support mesh trays.

[0008] The washing tower body is equipped with a drive shaft that rotates along its own axis. The drive shaft moves through multiple support mesh plates from bottom to top. A vibration component is installed between the drive shaft and the support mesh plates. A drive motor is installed at the bottom of the washing tower body. A transmission component is connected between the drive motor and the drive shaft.

[0009] Under the rotation of the drive shaft, multiple vibration components vibrate alternately.

[0010] By using multiple support mesh panels in conjunction with vibration components, the vibration components can vibrate alternately, causing the packing material on the multiple support mesh panels to vibrate alternately. This ensures that the packing material on at least one support mesh panel remains stationary, thereby guaranteeing stable filtration of exhaust gas.

[0011] Furthermore, the vibration assembly includes a fixed ring, a rotating ring, a plurality of first protrusions, and a plurality of second protrusions;

[0012] The fixing ring is coaxially mounted on the bottom surface of the supporting mesh disk, and multiple first protrusions are equidistantly mounted on the bottom surface of the fixing ring;

[0013] The rotating ring is coaxially fixed to the drive shaft by a bracket. Multiple second protrusions are divided into several groups, and the groups of second protrusions are equidistantly distributed on the upper end face of the rotating ring. Multiple second protrusions in one group are equidistantly installed on the rotating ring.

[0014] The first protrusions in the multiple vibration components are not set vertically, while the second protrusions in the multiple vibration components are set vertically.

[0015] Furthermore, multiple positioning sliding columns are fixed at equal intervals on the bottom periphery of the support mesh disk, and multiple positioning blocks are fixed at equal intervals on the inner wall of the washing tower body. The multiple positioning sliding columns are set one-to-one with the multiple positioning blocks and slide vertically through the positioning blocks.

[0016] Furthermore, the transmission assembly includes a first transmission gear and a second transmission gear. The first transmission gear is coaxially fixed to the output end of the drive motor, and the second transmission gear is coaxially fixed to the transmission shaft. The first transmission gear and the second transmission gear mesh with each other, and the diameter of the second transmission gear is larger than the diameter of the first transmission gear.

[0017] Furthermore, the drive shaft is a tube, and multiple spray pipes are horizontally fixed and connected at equal intervals at both the upper and lower ends of the drive shaft inside the washing tower body. Multiple atomizing nozzles are evenly distributed on the spray pipes.

[0018] The drive shaft extends to the end outside the washing tower body and is connected to the external water pipe through a sealed connector.

[0019] Furthermore, a sedimentation tank is installed at the bottom of the washing tower body, and the sedimentation tank is connected to the washing tower body.

[0020] Compared with existing technologies, the advantages of this utility model are:

[0021] (1) This scheme uses multiple support mesh disks in conjunction with vibration components to enable multiple vibration components to vibrate alternately, thereby causing the packing on multiple support mesh disks to vibrate alternately, keeping the packing on at least one support mesh disk in a stationary state at all times, thus ensuring stable filtration of exhaust gas.

[0022] (2) This scheme uses the combination of drive shaft and spray pipe. When the drive shaft rotates, it will drive multiple spray pipes that are fixed horizontally at its upper and lower ends to rotate synchronously. Since multiple atomizing nozzles are evenly distributed on the spray pipe, the atomizing nozzles can spray the inside of the scrubbing tower body in all directions during the rotation process, so that the washing liquid is evenly covered in the space where the exhaust gas flows, which greatly increases the contact area and contact time between the exhaust gas and the washing liquid, thereby more effectively washing and removing impurities and pollutants in the exhaust gas, and further enhancing the purification effect of the exhaust gas scrubbing tower.

[0032] The technical solution will now be clearly and completely described with reference to the accompanying drawings in the embodiments of this utility model.

[0033] First implementation method:

[0034] Please see Figures 1-7A waste gas scrubbing tower with an anti-clogging structure includes a scrubbing tower body 1 with an outlet 102 and an inlet 101 at its upper and lower ends, respectively. The scrubbing tower body 1 is filled with packing 3. The packing 3 can be made of conventional waste gas scrubbing tower waste gas purification materials, such as conventional multi-faceted hollow spherical packing 3. Multiple supporting mesh disks 2 (mesh holes not shown in the figure) are distributed equidistantly from top to bottom on the inner side of the scrubbing tower body 1. The packing 3 is evenly stacked on the upper surface of the multiple supporting mesh disks 2. Of course, the diameter of the packing 3 is larger than the mesh hole diameter of the supporting mesh disk 2.

[0035] The washing tower body 1 is equipped with a drive shaft 4 that rotates along its own axis. The drive shaft 4 moves through multiple support mesh trays 2 from bottom to top, and a vibration component 5 is provided between the drive shaft 4 and the support mesh trays 2. A drive motor 6 is installed at the bottom of the washing tower body 1. The drive motor 6 can be a conventional electric motor, such as a motor with the model number TZ155X020. A transmission component 7 is connected between the drive motor 6 and the drive shaft 4. Under the rotation of the drive shaft 4, the multiple vibration components 5 vibrate alternately.

[0036] Based on the above configuration of multiple support mesh disks 2 and vibration components 5, multiple vibration components 5 can vibrate alternately, thereby causing the packing material 3 on multiple support mesh disks 2 to vibrate alternately, keeping at least one packing material 3 on the support mesh disk 2 in a stationary state at all times, thus ensuring stable filtration of exhaust gas.

[0037] Specifically, the vibration assembly 5 includes a fixed ring 51, a rotating ring 52, multiple first protrusions 53 and multiple second protrusions 54. The fixed ring 51 is coaxially mounted on the bottom surface of the support mesh disk 2. The multiple first protrusions 53 are equidistantly mounted on the bottom surface of the fixed ring 51. The rotating ring 52 is coaxially fixed to the transmission shaft 4 through a bracket. The multiple second protrusions 54 are divided into several groups, and the several groups of second protrusions 54 are equidistantly distributed on the upper surface of the rotating ring 52. Multiple second protrusions 54 in one group are equidistantly mounted on the rotating ring 52.

[0038] Based on the above structural arrangement, when the drive shaft 4 rotates, it drives the rotating ring 52, which is coaxially fixed on it, to rotate. The second protrusions 54 at different positions will contact and collide with the first protrusions 53 in turn, thereby generating vibration. This vibration is transmitted to the packing 3 through the support mesh disk 2, causing the packing 3 on the support mesh disk 2 to vibrate. The packing 3 rolls and misaligns with each other, and uses the friction of adjacent packing 3 to remove the surface deposits, thus achieving self-cleaning.

[0039] Furthermore, since the first protrusions 53 in the multiple vibration components 5 are not vertically aligned, while the second protrusions 54 in the multiple vibration components 5 are vertically aligned, the packing material 3 on at least one support mesh disk 2 can be kept stationary at all times to stably filter the exhaust gas.

[0040] The bottom circumference of the support mesh disk 2 is fixed with multiple positioning sliding columns 9 at equal intervals, and the inner wall of the washing tower body 1 is fixed with multiple positioning blocks 8 at equal intervals. The multiple positioning sliding columns 9 are arranged one-to-one with the multiple positioning blocks 8 and slide vertically through the positioning blocks 8. This structure can ensure that the support mesh disk 2 can only move up and down in the vertical direction during vibration, and will not deviate in the horizontal direction, thereby ensuring the stability of the entire device and further ensuring the stable filtration effect of the exhaust gas.

[0041] The transmission assembly 7 includes a first transmission gear 71 and a second transmission gear 72. The first transmission gear 71 is coaxially fixed to the output end of the drive motor 6, and the second transmission gear 72 is coaxially fixed to the transmission shaft 4. The first transmission gear 71 and the second transmission gear 72 mesh with each other, and the diameter of the second transmission gear 72 is larger than the diameter of the first transmission gear 71. When the drive motor 6 starts, the first transmission gear 71 rotates accordingly. Since the first transmission gear 71 and the second transmission gear 72 mesh with each other, and the diameter of the second transmission gear 72 is larger than the diameter of the first transmission gear 71, according to the principle of gear transmission, it can play a role in reducing speed and increasing torque, so that the transmission shaft 4 rotates at a suitable speed.

[0042] Second implementation method:

[0043] Based on the first embodiment, the drive shaft 4 is a tube body. Both the upper and lower ends of the drive shaft 4 are horizontally fixed and connected at equal intervals inside the washing tower body 1, and multiple spray pipes 401 are equidistantly and integrally distributed on the spray pipes 401.

[0044] When the drive shaft 4 rotates, it drives multiple spray pipes 401, which are horizontally fixed at its upper and lower ends, to rotate synchronously. Since multiple atomizing nozzles are equidistantly and integrally distributed on the spray pipes 401, the atomizing nozzles can spray the interior of the scrubbing tower body 1 in all directions during the rotation process. This makes the scrubbing liquid evenly cover the space where the exhaust gas flows, greatly increasing the contact area and contact time between the exhaust gas and the scrubbing liquid. This makes it more effective in washing and removing impurities and pollutants in the exhaust gas, further enhancing the purification effect of the exhaust gas scrubbing tower.

[0045] In addition, the end of the drive shaft 4 extending to the outside of the washing tower body 1 is connected to the external water pipe 402 through a sealing connector 403. The sealing connector 403 can be a conventional rotary joint. This connection method not only ensures the sealing between the water pipe 402 and the drive shaft 4 to prevent the washing liquid from leaking, but also ensures that the water pipe 402 stably delivers the washing liquid into the drive shaft 4, thus ensuring the continuous and stable operation of the spraying operation.

[0046] In addition, a sedimentation tank 10 is installed at the bottom of the washing tower body 1. The sedimentation tank 10 is connected to the washing tower body 1. Of course, conventional filtration equipment (not shown in the figure) can be installed inside the sedimentation tank 10. The filtered water can be recycled, which can reduce water waste and reduce environmental pollution. In addition, a conventional drain port (not shown in the figure) is provided at the bottom of the side wall of the sedimentation tank 10. A valve can be installed on the drain port. When the impurities in the sedimentation chamber accumulate to a certain extent, the valve can be opened to discharge the impurities.

[0047] It should be noted that the specific models and specifications of the electrical equipment involved in this solution need to be selected and determined according to the actual specifications of the device. The specific selection and calculation methods adopt existing technologies in this field, so they will not be described in detail here. The power supply and principles of the electrical equipment involved are clear to those skilled in the art, and will not be described in detail here.

[0048] The above description is merely a preferred embodiment of this utility model; it encompasses all the protection scope of this utility model. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be covered within the protection scope of this utility model.
