Description

Technical Field

[0001] The present invention belongs to the technical field of flue gas desulfurization, and specifically relates to a multi-layer flow adsorption type flue gas desulfurization tower. Background Art

[0002] A desulfurization tower is a tower device for desulfurizing waste gas such as flue gas generated after coal combustion. It mainly removes sulfur-containing compounds in the flue gas through chemical absorption or physical adsorption. In order to improve the desulfurization efficiency of the desulfurization tower, the multi-layer flow adsorption method is generally adopted when the desulfurization tower is in use, so that different adsorption layers can adsorb sulfur dioxide particles of different particle sizes or sulfur-containing compounds in different states.

[0003] However, during the use of the existing multi-layer flow adsorption type flue gas desulfurization tower, since the distance between several adsorption beds cannot be adjusted, it is easy to cause uneven distribution of flue gas among the beds. When the distance between several adsorption beds is inappropriate, the flue gas to be desulfurized is likely to form a high-speed channel in some areas, causing some flue gas to flow out of the adsorption bed quickly without being fully adsorbed, reducing the adsorption effect and efficiency of the adsorption bed. At the same time, it also results in a short contact time between the flue gas and the adsorption bed, making it difficult for the adsorption bed to thoroughly remove sulfur-containing compounds in the flue gas, resulting in sulfur-containing compounds still being contained in the discharged flue gas, thus causing environmental pollution, not only reducing the use effect of the desulfurization tower, but also making the desulfurization tower have strong limitations during use.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] (1) The displacement lead screw rotates, causing the displacement block connected by its thread to move. The displacement block moves within the displacement square groove through the displacement slider on the opposite side, and thus drives the adsorption bed layer to move under the action of the extension block, enabling it to move within the tower in a limited manner and adjusting the distance between different adsorption bed layers. This avoids the uneven distribution of flue gas between the beds due to the inability to adjust the spacing between several adsorption bed layers. At the same time, it also avoids the formation of high-speed channels for the flue gas to be desulfurized in some areas when the spacing between different adsorption bed layers is inappropriate, preventing some flue gas from flowing out through the adsorption bed layer without sufficient adsorption. This improves the adsorption effect and efficiency of the adsorption bed layer, further avoiding the short contact time between the flue gas and the adsorption bed layer, enabling the adsorption bed layer to completely remove the sulfur compounds in the flue gas, and preventing sulfur compounds from being mixed in the discharged flue gas. Thereby, it further improves the use and desulfurization effect and efficiency of the desulfurization tower, avoids polluting the surrounding environment, and reduces the limitations of the desulfurization tower during use;

[0017] (2) A number of retaining square plates are in contact with the top and bottom of the adsorption bed layer respectively, thus limiting the adsorption bed layer in its current position and completing the installation operation of the adsorption bed layer. At the same time, during installation, the provided rubber buffer pads can also increase the friction between the retaining square plates and the adsorption bed layer, preventing phenomena such as shaking and dislocation of the adsorption bed layer during use, and improving the installation effect of the adsorption bed layer. At the same time, the installation and disassembly operations of the adsorption bed layer are convenient and fast, and can be completed without the aid of any tools, reducing the limitations of the desulfurization tower during use, enabling it to replace and use different adsorption bed layers according to different desulfurization requirements, and improving the desulfurization effect of the desulfurization tower. When the adsorption bed layer adjusts its position through the position-changing and distance-locking structural member, it also moves within the storage long box in a limited manner, driving the retaining square plate to displace, so that the top and bottom of the adsorption bed layer are always within the contact range of the retaining square plate, keeping the rubber buffer pads and the retaining springs in a buffered state, thus preventing phenomena such as dislocation of the adsorption bed layer during position adjustment and improving the installation effect of the adsorption bed layer;

[0018] (3) Since the strength of the high-pressure spring is greater than that of the positioning spring, when the positioning tooth block has engaged with the driving gear and the positioning slider has not yet been reset and moved in place, the continuous reset movement of the positioning slider causes the T-shaped square plate on it to move within the positioning cylinder in a limited manner, putting the positioning spring in a buffered state, thereby strengthening the contact strength between the positioning tooth block and the driving gear, and further preventing displacement of the positioning tooth block and the driving gear due to non-human factors during use, improving the desulfurization effect of the desulfurization tower;

[0019] (4) When the adsorption bed layer is moving, it also causes the extension block to be limited in movement at the extension slot, avoiding phenomena such as shaking when the extension block is moving and improving the stability of the adsorption bed layer during position adjustment; at the same time, when the extension block is moving, it will also drive the shielding long plate to move, making it always move at the extension slot, so as to always shield the extension slot, thus preventing the flue gas in the desulfurization tower from entering the storage long box and improving the desulfurization effect of the desulfurization tower;

[0020] (5) The auxiliary gear rotates and meshes with the rotating tooth ring to rotate, so that the rotating block on it rotates in a limited way in the rotating annular groove. Thus, under the action of the connecting shaft body, the first rotating shaft body is driven to rotate. The elastic rod at the bottom end of the first rotating shaft body drives the second rotating shaft body to rotate. Under the action of the elastic rod at the bottom end of the second rotating shaft body, the third rotating shaft body is driven to rotate, so that the three rotating shaft bodies all rotate and drive a number of scrapers to rotate, enabling the impurities adsorbed on the adsorption bed layer to be cleaned, avoiding excessive impurities adsorbed on the adsorption bed layer during use from affecting its desulfurization effect on the flue gas, and at the same time increasing the service life of the adsorption bed layer, avoiding the need for frequent manual removal of the adsorption bed layer for cleaning, and reducing the limitations in the use of the desulfurization tower;

[0021] (6) When it is necessary to synchronously adjust the positions of the three adsorption bed layers, the three transmission gears at their positions are all moved to the corresponding drive gears, so that the transmission gears and drive gears at each adsorption bed layer are meshed. By rotating any one of the drive gears, it meshes with the transmission gear to rotate, thereby driving the other two transmission gears on the rotating shaft to rotate, and making them mesh with the corresponding drive gears to rotate, so that the displacement lead screws on each adsorption bed layer rotate synchronously, thus driving a number of adsorption bed layers to rotate synchronously, reducing the time required for adjusting the adsorption bed layer, and to a certain extent reducing the time required for adjusting the position of the adsorption bed layer and reducing the limitations in the use of the desulfurization tower; enabling the operator to adjust the synchronous movement of different adsorption bed layers as needed, reducing the time for adjusting the position of the adsorption bed layer, and improving the use effect and desulfurization effect of the desulfurization tower; at the same time, when the position of the transmission gear is adjusted and the limit slide column is released, it drives the limit slide column to reset and move through the reset of the limit spring, and the end close to the rotating shaft enters any one of the guide slots, so as to limit the transmission gear at the current position, avoiding phenomena such as shaking or dislocation of the transmission gear during use, and improving the use effect of the desulfurization tower;

[0022] (7) After the positioning tooth block moves, it no longer meshes with the driving gear, thus releasing the limit setting for the driving gear, enabling the position of the adsorption bed layer to be adjusted by the position-changing lock distance structural member; when the position adjustment of the adsorption bed layer is completed, by loosening the positioning slider, the reset of the high-pressure spring drives the positioning slider to move back, which drives the T-shaped square plate to move back, and under the action of the positioning cylinder and the positioning spring, drives the positioning tooth block to move towards the driving gear and contact it, so that the positioning tooth block meshes with the driving gear to set its limit, preventing the driving gear from rotating, avoiding the displacement of the adsorption bed layer in the tower body due to non-human factors during use, reducing the limitations of the desulfurization tower during use, and enhancing the safety of the adsorption bed layer during use;

[0023] (8) When it is necessary to operate and rotate the scraping and attaching module to clean the impurities adsorbed on the adsorption bed layer, by pulling the limiting slide post outwards, it is limited to move on the limiting base, making the limiting spring in a buffered state, and then making the limiting slide post move away from the rotating shaft, so that the limiting slide post no longer connects with the guiding slot, thus releasing the limit setting for the vertical movement of the transmission gear, enabling the positioning circular groove on it to be limited and slide in the rotating shaft, thereby adjusting the position of the transmission gear on the rotating shaft, and adjusting the transmission gear to the meshing position with the driving gear. When it is necessary to operate the position-changing lock distance structural member to adjust the position of the adsorption bed layer, the driving gear needs to be rotated, and when it rotates, it will mesh with the transmission gear to rotate. Since the clamping slot on the positioning circular groove contacts the clamping block on the outer side wall of the rotating shaft, the rotating shaft can be driven to rotate, and through the action of the gear acceleration box, the auxiliary gear rotates rapidly, so that it meshes with the rotating tooth ring to rotate, enabling the scraping and attaching module to clean the adsorption bed layer.

DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0041] Example, byFigures 1 to 13 Given that, the present invention includes a tower body 1; three adsorption bed layers 2 with the same diameter as the tower body 1 are further provided inside the tower body 1, and the three adsorption bed layers 2 are respectively a physical adsorption layer, a chemical adsorption layer and an ion adsorption layer; a storage long box 3 is installed on the inner wall of the tower body 1, and the adsorption bed layer 2 is slidably matched with the storage long box 3; three groups of parallel fixing devices are arranged on the storage long box 3, and the three groups of parallel fixing devices are respectively used for installing the three adsorption bed layers 2; three displacement screw rods 4 arranged at equal intervals are further provided inside the storage long box 3, and the three displacement screw rods 4 respectively correspond to the positions of the three adsorption bed layers 2 one by one; a position-changing locking distance structural member is installed on the displacement screw rod 4, and the position-changing locking distance structural member is used for adjusting the position of the adsorption bed layer 2 inside the tower body 1; rotating bearings 5 are provided at the centers of the three adsorption bed layers 2, and a rotating scraping module is further provided on the rotating bearing 5, and the rotating scraping module is used for cleaning the impurities adsorbed on the adsorption bed layer 2; two symmetrical displacement bases 6 are installed on the displacement screw rod 4, and the displacement bases 6 are fixedly connected inside the storage long box 3;

[0042] After the flue gas enters through the inlet pipe on the side wall of the tower body 1, the sulfur-containing compounds in the flue gas are treated by multiple adsorption bed layers 2 inside the tower body 1. These adsorption bed layers 2 can be a physical adsorption layer, a chemical adsorption layer or an ion adsorption layer, and the three can be used in combination or separately according to the actual situation. At the same time, spraying can be combined to further improve the desulfurization effect and efficiency of the equipment. By setting the adsorption bed layer 2 as multiple layers, a larger adsorption area can be provided, and at the same time, the adsorption load can be shared, the service time of the adsorption bed layer 2 is extended, the desulfurization effect of the equipment is further improved, and the limitation of the desulfurization tower during use is reduced.

[0043] The displacement lock distance structural member of this embodiment includes a displacement square block 7 threadedly connected to a displacement lead screw 4. Displacement sliders are provided on opposite sides of the displacement square block 7, and the displacement sliders are slidably connected to displacement square grooves provided on the inner opposite surfaces of a storage long box 3; an extension square block 8 is further installed on the side surface of the displacement square block 7, and the extension square block 8 passes through the storage long box 3 and is connected to an adsorption bed layer 2; an extension square groove 9 is provided through the same side of the storage long box 3 and the extension square block 8, and the extension square groove 9 is slidably connected to the extension square block 8; two shielding long plates 10 are provided through the top of the extension square block 8, the extension square groove 9 is located between the two shielding long plates 10, and the size of the shielding long plates 10 is larger than that of the extension square groove 9; a displacement pulley 11 is installed on the displacement lead screw 4, a transmission belt 12 is connected to the displacement pulley 11, and the transmission belt 12 is further connected to a driving pulley 13, and the driving pulley 13 is located at the outer wall of a tower body 1; the driving pulley 13 and the displacement pulley 11 are slidably engaged with the transmission belt 12; a driving rotating shaft 14 is installed on the driving pulley 13, a driving substrate 15 is connected to the driving rotating shaft 14, and the driving substrate 15 is installed on the outer side wall of the tower body 1; a driving gear 16 is further installed at one end of the driving rotating shaft 14 away from the driving pulley 13, and a handle is connected to the top of the driving gear 16;

[0044] By rotating the handle of the driving gear 16, when the driving gear 16 rotates, it drives the driving pulley 13 to rotate through the driving rotating shaft 14, which drives the displacement pulley 11 to rotate under the action of the transmission belt 12, causing the displacement lead screw 4 thereon to rotate, and the displacement square block 7 threadedly connected thereto to move. The displacement square block 7 moves in a limited manner in the displacement square groove through the displacement sliders on its opposite sides. Thus, under the action of the extension square block 8, the adsorption bed layer 2 is driven to move, enabling it to move in a limited manner within the tower body 1, and enabling the distance between different adsorption bed layers 2 to be adjusted. This avoids the uneven distribution of flue gas between the beds caused by the inability to adjust the spacing between several adsorption bed layers 2. At the same time, it also avoids the formation of high-speed channels for the flue gas to be desulfurized in some areas when the spacing between different adsorption bed layers 2 is inappropriate, preventing some flue gas from flowing out through the adsorption bed layer 2 without sufficient adsorption. This improves the adsorption effect and efficiency of the adsorption bed layer 2, further avoiding the short contact time between the flue gas and the adsorption bed layer 2, enabling the adsorption bed layer 2 to completely remove the sulfur-containing compounds in the flue gas, and preventing the flue gas discharged from being doped with sulfur-containing compounds. Thereby, it further improves the use of the desulfurization tower and the desulfurization effect and efficiency, avoids polluting the surrounding environment, and thus reduces the limitations of the desulfurization tower during use;

[0045] It is worth mentioning that when the adsorption bed layer 2 is moving, it also makes the extension block 8 move in a limited way at the extension slot 9, avoiding phenomena such as shaking when the extension block 8 is moving and at the same time improving the stability of the movement of the adsorption bed layer 2 when adjusting its position; at the same time, when the extension block 8 is moving, it will also drive the shielding long plate 10 to move, so that it has been moving at the extension slot 9, and can always shield the extension slot 9, thus preventing the flue gas in the desulfurization tower from entering the storage long box 3 and improving the desulfurization effect of the desulfurization tower.

[0046] The rotating scraping and attaching module of this embodiment includes a rotating shaft body 17 installed on the rotating bearing 5. A set of scraping plates 18 are installed at both ends of the rotating shaft body 17, and the two sets of scraping plates 18 are respectively located at the top and bottom of the adsorption bed layer 2; the number of each set of the scraping plates 18 is four; the rotating scraping and attaching module also includes two elastic rods 19; one end of one of the elastic rods 19 is respectively connected to the bottom end of the first rotating shaft body 17 and the top end of the second rotating shaft body 17; the two ends of the other elastic rod 19 are respectively connected to the bottom end of the second rotating shaft body 17 and the top end of the third rotating shaft body 17; a connecting shaft body 20 is installed at the top end of the first rotating shaft body 17, a rotating tooth ring 21 is installed around the connecting shaft body 20 through a connecting rod, and a rotating block 22 is installed at the bottom of the rotating tooth ring 21; a rotating annular groove 23 is provided on the tower body 1, and the rotating annular groove 23 is in sliding fit with the rotating block 22;

[0047] When the adsorption bed layer 2 is in use, a large amount of impurities will be adsorbed on its surface. When the adsorption bed layer 2 adjusts its position, it will make the auxiliary gear 41 rotate and mesh with the rotating tooth ring 21 to rotate, so that the rotating block 22 on it rotates in a limited way in the rotating annular groove 23. Thus, under the action of the connecting shaft body 20, the first rotating shaft body 17 is driven to rotate. The elastic rod 19 at the bottom end of the first rotating shaft body 17 drives the second rotating shaft body 17 to rotate. Under the action of the elastic rod 19 at the bottom end of the second rotating shaft body 17, the third rotating shaft body 17 is driven to rotate, so that the three rotating shaft bodies 17 all rotate and drive a number of scraping plates 18 to rotate, so as to clean the impurities adsorbed on the adsorption bed layer 2, avoid excessive impurities adsorbed on the adsorption bed layer 2 during use from affecting its desulfurization effect on flue gas, at the same time extend the service life of the adsorption bed layer 2, avoid the need to frequently manually remove the adsorption bed layer 2 for cleaning, and reduce the limitations during the use of the desulfurization tower.

[0048] A ratchet stop rotating member is further provided on the driving substrate 15 of this embodiment; the ratchet stop rotating member includes a positioning square column 24 installed on the side of the driving substrate 15 away from the tower body 1. A positioning slider 25 is slidably connected to the positioning square column 24. A T-shaped square plate 26 is connected to the positioning slider 25. Two symmetrically arranged positioning cylinders 27 penetrate through the side surface of the T-shaped square plate 26. The positioning cylinders 27 are slidably matched with the T-shaped square plate 26; one end of the two positioning cylinders 27 close to the driving gear 16 is commonly connected with a positioning tooth block 28; the driving gear 16 is located on the moving path of the positioning tooth block 28 and the two are meshed; a positioning spring 29 is sleeved on the positioning cylinder 27. One end of the positioning spring 29 is fixedly connected with the positioning tooth block 28, and the other end is fixedly connected with the T-shaped square plate 26; a high-pressure spring 30 is sleeved on the positioning square column 24. One end of the high-pressure spring 30 is fixedly connected with the positioning slider 25, and the other end is connected with a positioning limit plate 31. The positioning limit plate 31 is installed at the end of the positioning square column 24 away from the driving substrate 15;

[0049] When it is necessary to operate the transposition lock distance structure to adjust the position of the adsorption bed layer 2 in the tower body 1, it is necessary to rotate the driving gear 16. At this time, by pulling out the positioning slider 25 outward, it is limited to move on the positioning square column 24, so that the high-pressure spring 30 is in a buffered state, thereby driving the T-shaped square plate 26 to move. Under the action of the positioning cylinder 27 and the positioning spring 29, the positioning tooth block 28 is driven to move. It is worth mentioning that before the positioning tooth block 28 moves, the positioning spring 29 that was originally in a buffered state is gradually reset. After the positioning spring 29 is reset, the positioning tooth block 28 can be driven to no longer mesh with the driving gear 16, thereby releasing the limit setting of the driving gear 16, so that the transposition lock distance structure can adjust the position of the adsorption bed layer 2; when the position adjustment of the adsorption bed layer 2 is completed, by loosening the positioning slider 25, the reset of the high-pressure spring 30 drives the positioning slider 25 to reset and move, which drives the T-shaped square plate 26 to reset and move. Under the action of the positioning cylinder 27 and the positioning spring 29, the positioning tooth block 28 is driven to move towards the driving gear 16 and contact it, so that the positioning tooth block 28 meshes with the driving gear 16 to limit it, avoiding the rotation of the driving gear 16, so that the adsorption bed layer 2 can avoid displacement in the tower body 1 due to non-human factors during use, reducing the limitations of the desulfurization tower during use and improving the safety of the adsorption bed layer 2 during use; it is worth mentioning that since the strength of the high-pressure spring 30 is greater than that of the positioning spring 29, when the positioning tooth block 28 has meshed with the driving gear 16 and the positioning slider 25 has not yet reset and moved in place, the continuous reset and movement of the positioning slider 25 causes the T-shaped square plate 26 on it to be limited to move on the positioning cylinder 27, so that the positioning spring 29 is in a buffered state, thereby strengthening the contact strength between the positioning tooth block 28 and the driving gear 16, further avoiding displacement of the positioning tooth block 28 and the driving gear 16 due to non-human factors during use, and improving the desulfurization effect of the desulfurization tower.

[0050] The juxtaposition fixing device of this embodiment includes two fixing square plates 32 respectively located on the top and bottom of the adsorption bed layer 2. Rubber buffer pads 33 are provided on one side of several fixing square plates 32 close to the adsorption bed layer 2, and the rubber buffer pads 33 are attached to the adsorption bed layer 2; on the side of several said fixing square plates 32 away from the adsorption bed layer 2, fixing square columns 34 are provided. A fixing substrate 35 is slidably connected to the fixing square columns 34, and the fixing substrate 35 is fixedly installed on the storage long box 3; a fixing spring 36 is sleeved on the fixing square columns 34. One end of the fixing spring 36 is fixedly connected to the fixing substrate 35, and the other end is fixedly connected to the fixing square plate 32;

[0051] By pulling the retaining square column 34 to make it move in a limited way on the retaining base plate 35, the retaining spring 36 is in a buffered state, and then the retaining square plate 32 on the retaining square column 34 no longer contacts the adsorption bed layer 2, so as to release the limit setting for the adsorption bed layer 2, and the disassembly operation of the adsorption bed layer 2 can be completed; when the adsorption bed layer 2 needs to be installed, the adsorption bed layer 2 is placed between the two retaining square plates 32, the retaining square column 34 is released, and the retaining square plate 32 is driven to move back by the reset of the retaining spring 36, so that several retaining square plates 32 respectively contact the top and bottom of the adsorption bed layer 2, thereby positioning the adsorption bed layer 2 at the current position, and the installation operation of the adsorption bed layer 2 is completed; at the same time, when installing, the rubber buffer pad 33 provided can also increase the friction force between the retaining square plate 32 and the adsorption bed layer 2, avoiding phenomena such as shaking and dislocation of the adsorption bed layer 2 during use, and improving the installation effect of the adsorption bed layer 2; at the same time, the installation and disassembly operations of the adsorption bed layer 2 are convenient and fast, and can be completed without any tools, reducing the limitations of the desulfurization tower during use, enabling it to replace and use different adsorption bed layers 2 according to different desulfurization requirements, and improving the desulfurization effect of the desulfurization tower; when the adsorption bed layer 2 adjusts its position through the position-changing lock-distance structural member, it also moves in a limited way at the storage long box 3, thereby driving the displacement of the retaining square plate 32, so that the top and bottom of the adsorption bed layer 2 are always within the contact range of the retaining square plate 32, making the rubber buffer pad 33 and the retaining spring 36 both in a buffered state, thus avoiding phenomena such as dislocation of the adsorption bed layer 2 during position adjustment, and improving the installation effect of the adsorption bed layer 2.

[0052] In the tower body 1 of this embodiment, a transfer drive unit is further provided; the transfer drive unit includes an auxiliary base 37 installed on the outer side wall of the tower body 1, and a rotating shaft 38 is installed on the top of the auxiliary base 37; several guiding slots 39 are further provided on the outer side wall of the rotating shaft 38; one end of the rotating shaft 38 away from the auxiliary base 37 is further installed with a gear acceleration box 40, and the gear acceleration box 40 is installed at the outer side wall of the tower body 1; an auxiliary gear 41 is further provided on the top of the gear acceleration box 40, and the auxiliary gear 41 is meshed and connected with the rotating tooth ring 21; the transfer drive unit further includes a transmission gear 42 having the same number as the drive gear 16, a positioning circular groove 43 is provided through the center of the transmission gear 42, and the inner side wall of the positioning circular groove 43 is in fit with and slidably matched with the outer side wall of the rotating shaft 38; several clamping slots are provided on the inner side wall of the positioning circular groove 43, and the clamping slots are in slidable fit with the clamping blocks provided on the outer side wall of the rotating shaft 38; the drive gear 16 is located on the moving path of the transmission gear 42 and the two are meshed; a limiting base 44 is provided on the top of the transmission gear 42, a limiting sliding column 45 is connected through the side surface of the limiting base 44, and the limiting sliding column 45 is slidably matched with the limiting base 44; one end of the limiting sliding column 45 away from the rotating shaft 38 is connected with a limiting square plate 46; a limiting spring 47 is sleeved on the limiting sliding column 45, one end of the limiting spring 47 is connected with the limiting square plate 46, and the other end is connected with the limiting base 44; the guiding slot 39 is located on the moving path of the limiting sliding column 45;

[0053] When it is necessary to operate the rotating scraping and attaching module to clean the impurities adsorbed on the adsorption bed layer 2, the limit slide post 45 is pulled outwards, so that it moves in a limited way on the limit base 44, making the limit spring 47 in a buffered state. Then, the limit slide post 45 moves away from the rotating shaft 38, so that the limit slide post 45 is no longer connected to the guiding slot 39, thus releasing the limit setting for the vertical movement of the transmission gear 42. The positioning circular groove 43 on it slides in a limited way in the rotating shaft 38, so as to adjust the position of the transmission gear 42 on the rotating shaft 38, and then adjust the transmission gear 42 to the meshing position with the driving gear 16. When it is necessary to operate the position-changing and distance-locking structural member to adjust the position of the adsorption bed layer 2, the driving gear 16 needs to be rotated. When it rotates, it will mesh with the transmission gear 42 and rotate. Since the clamping groove on the positioning circular groove 43 contacts the clamping block on the outer side wall of the rotating shaft 38, the rotating shaft 38 can be driven to rotate. Through the action of the gear speed increasing box 40, the auxiliary gear 41 rotates rapidly, so as to mesh with the rotating toothed ring 21 and rotate, enabling the rotating scraping and attaching module to clean the adsorption bed layer 2. At the same time, when it is necessary to adjust the synchronous movement of several adsorption bed layer 2s simultaneously, the positions of the corresponding transmission gears 42 can be adjusted according to the several adsorption bed layer 2s that need to be synchronously moved, so that they mesh with the driving gears 16 at the positions of the adsorption bed layer 2s to be adjusted. For example, in the figure, there are the first, second, and third adsorption bed layer 2s from top to bottom. There is a driving gear 16 and a movable transmission gear 42 at each adsorption bed layer 2. For example, when it is necessary to synchronously adjust the positions of the three adsorption bed layer 2s, the three transmission gears 42 at their positions are all moved to the corresponding driving gears 16, so that the transmission gears 42 and the driving gears 16 at each adsorption bed layer 2 mesh. By rotating any one of the driving gears 16, it meshes with the transmission gear 42 and rotates, thus driving the other two transmission gears 42 on the rotating shaft 38 to rotate, and making them mesh with the corresponding driving gears 16 to rotate, so that the displacement lead screws 4 on each adsorption bed layer 2 rotate synchronously, thus driving several adsorption bed layer 2s to rotate synchronously, reducing the time required for adjusting the adsorption bed layer 2, and to a certain extent reducing the time required for adjusting the position of the adsorption bed layer 2, and reducing the limitations of the desulfurization tower during use. It enables the operator to adjust the synchronous movement of different adsorption bed layer 2s as needed, reducing the time for adjusting the position of the adsorption bed layer 2, and improving the use effect and desulfurization effect of the desulfurization tower. At the same time, when the position of the transmission gear 42 is adjusted and the limit slide post 45 is released, it drives the limit slide post 45 to move back to its original position through the reset of the limit spring 47, and the end close to the rotating shaft 38 enters into any one of the guiding slots 39, so as to limit the transmission gear 42 at the current position, avoiding phenomena such as shaking or dislocation of the transmission gear 42 during use, and improving the use effect of the desulfurization tower.
