Description

Technical Field

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

[0002] A desulfurization tower is a tower-type equipment that desulfurizes waste gas such as flue gas produced by coal combustion. It mainly removes sulfur-containing compounds in the flue gas by chemical absorption or physical adsorption. In order to improve the desulfurization efficiency of the desulfurization tower, the desulfurization tower generally adopts a multi-layer flow adsorption method when 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, in the use of the existing multi-layer flow adsorption flue gas desulfurization tower, it is difficult to adjust the spacing between several adsorption beds, which easily leads to uneven distribution of flue gas between the beds. When the spacing between several adsorption beds is not appropriate, the flue gas to be desulfurized is likely to form high-speed channels in some areas, causing part of the flue gas to quickly flow out through the adsorption bed without being fully adsorbed, reducing the adsorption effect and efficiency of the adsorption bed. At the same time, it also leads to a shorter contact time between the flue gas and the adsorption bed, making it difficult for the adsorption bed to completely clean the sulfur-containing compounds in the flue gas, resulting in the exhaust flue gas containing sulfur-containing compounds, thereby polluting the environment, which not only reduces the use effect of the desulfurization tower, but also makes the desulfurization tower have strong limitations when used.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) The displacement screw rotates to move the displacement block connected to it, so that it moves within the displacement square groove through the displacement slider on the opposite side, thereby driving the adsorption bed to move under the action of the extension block, so that it can move within the tower body, and adjust the distance between different adsorption beds, so as to avoid the uneven distribution of flue gas between the beds due to the inability to adjust the spacing between several adsorption beds. At the same time, it also avoids the formation of high-speed channels in some areas of the flue gas to be desulfurized if the spacing between different adsorption beds is not appropriate, and avoids part of the flue gas flowing out through the adsorption bed without being fully adsorbed, thereby improving the adsorption effect and efficiency of the adsorption bed, and further avoiding the short contact time between the flue gas and the adsorption bed, so that the adsorption bed can completely clean the sulfur-containing compounds in the flue gas, and avoid the exhaust The flue gas is mixed with sulfur-containing compounds, thereby further improving the use of the desulfurization tower and the desulfurization effect and efficiency, avoiding pollution to the surrounding environment, and reducing the limitations of the desulfurization tower when in use;

[0017] (2) A plurality of retaining square plates are in contact with the top and bottom of the adsorption bed respectively, thereby limiting the adsorption bed at the current position, thereby completing the installation of the adsorption bed; at the same time, during installation, the friction between the retaining square plates and the adsorption bed can be increased by the provided rubber buffer pads, thereby preventing the adsorption bed from shaking and dislocating during use, thereby improving the installation effect of the adsorption bed; at the same time, the installation and disassembly of the adsorption bed are convenient and quick, and can be completed without the aid of any tools, thereby reducing the limitations of the desulfurization tower during use, so that different adsorption beds can be replaced and used according to different desulfurization requirements, thereby improving the desulfurization effect of the desulfurization tower; when the adsorption bed is adjusted in position by means of the displacement locking structure, it is also limited and moved at the storage box, thereby driving the displacement of the retaining square plates, so that the top and bottom of the adsorption bed are always within the contact range of the retaining square plates, so that the rubber buffer pads and the retaining springs are in a buffering state, thereby preventing the adsorption bed from dislocating when adjusting its position, thereby improving the installation effect of the adsorption bed;

[0018] (3) Since the strength of the high-pressure spring is greater than that of the positioning spring, when the positioning tooth block has been meshed with the driving gear, the positioning slider has not yet reset to its position. The continued reset movement of the positioning slider causes the T-shaped square plate on it to move to the upper limit of the positioning cylinder, so that the positioning spring is in a buffering state, thereby strengthening the contact strength between the positioning tooth block and the driving gear, further avoiding the displacement of the positioning tooth block and the driving gear due to non-human factors during use, and improving the desulfurization effect of the desulfurization tower;

[0019] (4) When the adsorption bed is moving, the extension block is limited to move at the extension square groove, which prevents the extension block from shaking during movement and improves the stability of the adsorption bed when adjusting its position; at the same time, the extension block will also drive the shielding long plate to move when moving, so that it is always located at the extension square groove and can always shield the extension square groove, thereby preventing the flue gas in the desulfurization tower from entering the storage long box, thereby improving the desulfurization effect of the desulfurization tower;

[0020] (5) The auxiliary gear rotates and meshes with the rotating gear ring to rotate, so that the rotating block on it rotates within the rotating annular groove, thereby driving the first rotating shaft to rotate under the action of the connecting shaft, and the elastic rod at the bottom end of the first rotating shaft drives the second rotating shaft to rotate, and the elastic rod at the bottom end of the second rotating shaft drives the third rotating shaft to rotate, so that all three rotating shafts rotate and drive a number of scrapers to rotate, so that the impurities adsorbed on the adsorption bed can be cleaned, avoiding the adsorption bed from adsorbing too many impurities during use and affecting its desulfurization effect on the flue gas. At the same time, the service life of the adsorption bed is increased, avoiding the need for frequent manual removal of the adsorption bed for cleaning, and reducing the limitations of the desulfurization tower during use;

[0021] (6) When the positions of the three adsorption beds need to be adjusted synchronously, the three transmission gears at the beds are moved to the corresponding drive gears, so that the transmission gears at each adsorption bed are meshed with the drive gears. By rotating any one of the drive gears, it is meshed with the transmission gear and rotates, thereby driving the other two transmission gears on the rotating shaft to rotate and mesh with the corresponding drive gears, so that the displacement screws on each adsorption bed rotate synchronously, thereby driving several adsorption beds to rotate synchronously, reducing the time required for adjusting the adsorption beds, and to a certain extent reducing the time required for adjusting the positions of the adsorption beds, thereby reducing the limitations of the desulfurization tower during use; allowing the operator to adjust the synchronous movement of different adsorption beds as needed, thereby reducing the time for adjusting the positions of the adsorption beds, 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, the limit slide is released, so that the limit slide is reset and moved by the reset of the limit spring, so that the end close to the rotating shaft enters any guide slot, thereby limiting the transmission gear at the current position, avoiding 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 is no longer engaged with the driving gear, thereby releasing the limit setting of the driving gear, so that the position of the adsorption bed can be adjusted by the shifting lock distance structure; when the position adjustment of the adsorption bed is completed, the positioning slider is released to reset the high-pressure spring, thereby driving the positioning slider to reset and move, so that it drives the T-shaped square plate to reset and move, so that the positioning tooth block is driven by the positioning cylinder and the positioning spring to move toward the direction of the driving gear and contact it, so that the positioning tooth block is engaged with the driving gear to limit its position, thereby preventing the driving gear from rotating, so that the adsorption bed is prevented from being displaced in the tower body due to non-human factors during use, reducing the limitations of the desulfurization tower during use, and improving the safety of the adsorption bed during use;

[0023] (8) When it is necessary to operate the rotary scraping module to clean the impurities adsorbed on the adsorption bed, the limit slide is pulled outward to move within the limit limit of the limit base, so that the limit spring is in a buffer state, and then the limit slide is moved away from the rotating shaft, so that the limit slide is no longer connected to the guide slot, thereby releasing the limit setting for the vertical movement of the transmission gear, so that the positioning circular groove on it slides within the rotating shaft, thereby adjusting the position of the transmission gear on the rotating shaft, thereby adjusting the transmission gear to a position that meshes with the driving gear. When it is necessary to operate the shift locking structure to adjust the position of the adsorption bed, it is necessary to rotate the driving gear so that it will mesh with the transmission gear when it rotates. Since the card groove on the positioning circular groove contacts the card block on the outer wall of the rotating shaft, the rotating shaft is driven to rotate, so that the auxiliary gear is rotated rapidly under the action of the gear speed increase box, so that it can mesh with the rotating gear ring to rotate, so that the rotary scraping module can clean the adsorption bed.

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, by Figures 1 to 13 The present invention comprises a tower body 1; the tower body 1 is also provided with three adsorption beds 2 of the same diameter as the tower body 1, and the three adsorption beds 2 are respectively a physical adsorption layer, a chemical adsorption layer and an ion adsorption layer; a long storage box 3 is installed on the inner wall of the tower body 1, and the adsorption bed 2 is slidably matched with the long storage box 3; three sets of parallel fixing devices are arranged on the long storage box 3, and the three sets of parallel fixing devices are respectively used to install the three adsorption beds 2; the long storage box 3 is also provided with three displacement screw rods 4 arranged equidistantly, and the three The displacement screw 4 corresponds to the positions of the three adsorption beds 2 respectively; a displacement locking structure is installed on the displacement screw 4, and the displacement locking structure is used to adjust the position of the adsorption bed 2 in the tower body 1; a rotating bearing 5 is provided at the center of the three adsorption beds 2, and a rotating scraping module is also provided on the rotating bearing 5, and the rotating scraping module is used to clean the impurities adsorbed on the adsorption bed 2; two symmetrical displacement bases 6 are installed on the displacement screw 4, and the displacement base 6 is fixedly connected to the storage long box 3;

[0042] After the flue gas enters through the air inlet pipe on the side wall of the tower body 1, the sulfur-containing compounds in the flue gas are treated by multiple adsorption beds 2 in the tower body 1. These adsorption beds 2 can be physical adsorption layers, chemical adsorption layers or ion adsorption layers. The three can be used in combination or separately according to actual conditions. At the same time, they can also be used in combination with spraying to further improve the desulfurization effect and efficiency of the equipment. By setting the adsorption bed 2 as a multi-layer, a larger adsorption area can be provided, and the adsorption load can be shared at the same time, which extends the service life of the adsorption bed 2, further improves the desulfurization effect of the equipment, and reduces the limitations of the desulfurization tower during use.

[0043] The displacement locking structure of this embodiment includes a displacement block 7 threadedly connected to the displacement screw rod 4, a displacement slider is provided on the opposite side of the displacement block 7, and the displacement slider is slidably connected to the displacement square groove provided on the opposite inner surface of the storage long box 3; an extension block 8 is also installed on the side of the displacement block 7, and the extension block 8 passes through the storage long box 3 and is connected to the adsorption bed 2; an extension square groove 9 is penetrated on the same side of the storage long box 3 and the extension block 8, and the extension square groove 9 is slidably connected to the extension block 8; two shielding long plates 10 are penetrated on the top of the extension block 8, and the extension square groove 9 is located between the two shielding long plates 10, and the shielding long plates The size of 10 is larger than the extended square groove 9; a displacement pulley 11 is installed on the displacement screw rod 4, and a transmission belt 12 is connected to the displacement pulley 11, and the transmission belt 12 is also connected to a driving pulley 13, and the driving pulley 13 is located at the outer wall of the tower body 1; the driving pulley 13 and the displacement pulley 11 are slidably matched with the transmission belt 12; a driving shaft 14 is installed on the driving pulley 13, and a driving base plate 15 is connected to the driving shaft 14, and the driving base plate 15 is installed on the outer wall of the tower body 1; a driving gear 16 is also installed on the end of the driving shaft 14 away from the driving pulley 13, and a handle is connected to the top of the driving gear 16;

[0044] By turning the handle of the driving gear 16, the driving gear 16 rotates, and the driving pulley 13 is driven to rotate through the driving shaft 14, so that the displacement pulley 11 is driven to rotate under the action of the transmission belt 12, so that the displacement screw 4 on it is rotated, and the displacement block 7 connected with it is moved, so that it is limited and moved in the displacement square groove through the displacement slider on the opposite side, so that the adsorption bed 2 is driven to move under the action of the extension block 8, so that it can be limited and moved in the tower body 1, so that the distance between different adsorption beds 2 can be adjusted, so as to avoid that the spacing between several adsorption beds 2 cannot be adjusted, resulting in uneven distribution of flue gas between the beds, and at the same time If the spacing between different adsorption beds 2 is not appropriate, it is avoided that the flue gas to be desulfurized will easily form high-speed channels in some areas, and some flue gas will not flow out through the adsorption bed 2 without being fully adsorbed, thereby improving the adsorption effect and efficiency of the adsorption bed 2, and further avoiding the short contact time between the flue gas and the adsorption bed 2, so that the adsorption bed 2 can completely clean the sulfur-containing compounds in the flue gas, and avoid the exhaust flue gas being mixed with sulfur-containing compounds, thereby further improving the use of the desulfurization tower and the desulfurization effect and efficiency, avoiding pollution to the surrounding environment, and reducing the limitations of the desulfurization tower when in use;

[0045] It is worth mentioning that when the adsorption bed 2 is moving, the extended block 8 is also limited in movement at the extended square groove 9, which avoids the extended block 8 from shaking during movement and improves the stability of the adsorption bed 2 when adjusting its position; at the same time, the extended block 8 will also drive the shielding long plate 10 to move when moving, so that it is always located at the extended square groove 9 and can always shield the extended square groove 9, thereby preventing the flue gas in the desulfurization tower from entering the storage long box 3, thereby improving the desulfurization effect of the desulfurization tower.

[0046] The rotary scraping module of this embodiment includes a rotating shaft body 17 mounted on a rotating bearing 5, and a group of scrapers 18 are installed at both ends of the rotating shaft body 17, and the two groups of scrapers 18 are respectively located at the top and bottom of the adsorption bed 2; the number of scrapers 18 in each group is four; the rotary scraping module also includes two elastic rods 19; the two ends of one of the elastic rods 19 are 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 of the first rotating shaft body 17, and a rotating gear ring 21 is installed around the connecting shaft body 20 through a connecting rod, and a rotating rotating block 22 is installed at the bottom of the rotating gear ring 21; a rotating annular groove 23 is provided on the tower body 1, and the rotating annular groove 23 is slidably matched with the rotating rotating block 22;

[0047] When the adsorption bed 2 is in use, a large amount of impurities will be adsorbed on its surface. When the adsorption bed 2 is in an adjusted position, the auxiliary gear 41 will rotate and engage the rotating gear ring 21 to rotate, so that the rotating block 22 thereon will rotate within the rotating annular groove 23 within a limited position, thereby driving the first rotating shaft 17 to rotate under the action of the connecting shaft 20, and the elastic rod 19 at the bottom end of the first rotating shaft 17 drives the second rotating shaft 17 to rotate, and the third rotating shaft 17 is driven to rotate under the action of the elastic rod 19 at the bottom end of the second rotating shaft 17, so that all three rotating shafts 17 rotate and drive a number of scrapers 18 to rotate, so that the impurities adsorbed on the adsorption bed 2 can be cleaned, so as to avoid the adsorption bed 2 absorbing too many impurities during use and affecting its desulfurization effect on the flue gas, and at the same time, the service life of the adsorption bed 2 is increased, avoiding the need for frequent manual removal of the adsorption bed 2 for cleaning, and reducing the limitations of the desulfurization tower during use.

[0048] The driving substrate 15 of this embodiment is also provided with an engaging rotating member; the engaging 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, and a T-shaped square plate 26 is connected to the positioning slider 25. The side of the T-shaped square plate 26 is penetrated by two symmetrically arranged positioning cylinders 27, and 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 to 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 to the positioning tooth block 28, and the other end is fixedly connected to 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 to the positioning slider 25, and the other end is connected to a positioning limit plate 31, and 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 locking structure to adjust the position of the adsorption bed 2 in the tower body 1, the driving gear 16 needs to be rotated. At this time, the positioning slider 25 is pulled outward to make it move within the upper limit position of the positioning square column 24, so that the high-pressure spring 30 is in a buffering state, thereby driving the T-shaped square plate 26 to move, so that it drives the positioning tooth block 28 to move under the action of the positioning cylinder 27 and the positioning spring 29. It is worth mentioning that before the positioning tooth block 28 moves, the positioning spring 29, which was originally in a buffering state, is gradually reset. Only when the positioning spring 29 is reset can it drive the positioning tooth block 28 so that it no longer meshes with the driving gear 16, thereby releasing the limit setting of the driving gear 16, so that the transposition locking structure can adjust the position of the adsorption bed 2; when the position adjustment of the adsorption bed 2 is completed, the positioning slider 25 is released to reset the high-pressure spring 30, thereby driving the positioning slider 25 to reset and move, so that it drives the T-shaped square plate 26 to reset and move, so that it is between the positioning cylinder 27 and the positioning The spring 29 drives the positioning tooth block 28 to move toward and contact the driving gear 16, so that the positioning tooth block 28 engages with the driving gear 16 to limit it and prevent the driving gear 16 from rotating, so that the adsorption bed 2 is prevented from being displaced in the tower body 1 due to non-human factors during use, thereby reducing the limitations of the desulfurization tower during use and improving the safety of the adsorption bed 2 during use; it is worth mentioning that since the strength of the high-pressure spring 30 is greater than the positioning spring 29, when the positioning tooth block 28 has engaged with the driving gear 16, the positioning slider 25 has not yet reset to its position, and the continued reset movement of the positioning slider 25 causes the T-shaped square plate 26 on it to move within the upper limit of the positioning cylinder 27, so that the positioning spring 29 is in a buffering state, thereby strengthening the contact strength between the positioning tooth block 28 and the driving gear 16, further preventing the positioning tooth block 28 and the driving gear 16 from being displaced due to non-human factors during use, and improving the desulfurization effect of the desulfurization tower.

[0050] The parallel fixing device of this embodiment includes two fixing square plates 32 located on the top and bottom of the adsorption bed 2.

[0051] By pulling the retaining square column 34, it moves to the upper limit position on the retaining base plate 35, so that the retaining spring 36 is in a buffering state, and then the retaining square plate 32 on the retaining square column 34 no longer contacts the adsorption bed 2, thereby releasing the limit setting of the adsorption bed 2, and the disassembly operation of the adsorption bed 2 can be completed; when the adsorption bed 2 needs to be installed, the adsorption bed 2 is placed between the two retaining square plates 32, and the retaining square column 34 is loosened. The retaining square plate 32 is driven to reset and move by the reset of the retaining spring 36, so that several retaining square plates 32 are respectively in contact with the top and bottom of the adsorption bed 2, thereby limiting the adsorption bed 2 to the current position, thereby completing the installation operation of the adsorption bed 2; at the same time, during installation, the friction between the retaining square plate 32 and the adsorption bed 2 can be increased by the provided rubber buffer pad 33. The adsorption bed 2 is prevented from shaking and dislocating during use, thereby improving the installation effect of the adsorption bed 2; at the same time, the installation and disassembly operations of the adsorption bed 2 are convenient and quick, and can be completed without the aid of any tools, thereby reducing the limitations of the desulfurization tower during use, so that different adsorption beds 2 can be replaced and used according to different desulfurization needs, thereby improving the desulfurization effect of the desulfurization tower; when the adsorption bed 2 is adjusted in position by the transposition locking structure, it is also limited and moved at the storage long box 3, thereby driving the fixed square plate 32 to move, so that the top and bottom of the adsorption bed 2 are always within the contact range of the fixed square plate 32, so that the rubber buffer pad 33 and the retaining spring 36 are both in a buffering state, thereby preventing the adsorption bed 2 from dislocating when adjusting its position, thereby improving the installation effect of the adsorption bed 2.

[0052] The tower body 1 of this embodiment is also provided with a transfer transmission unit; the transfer transmission unit includes an auxiliary base 37 installed on the outer wall of the tower body 1, and a rotating shaft 38 is installed on the top of the auxiliary base 37; a plurality of guide slots 39 are also provided on the outer wall of the rotating shaft 38; a gear speed-up box 40 is also installed on the end of the rotating shaft 38 away from the auxiliary base 37, and the gear speed-up box 40 is installed on the outer wall of the tower body 1; an auxiliary gear 41 is also provided on the top of the gear speed-up box 40, and the auxiliary gear 41 is meshed and connected with the rotating gear ring 21; the transfer transmission unit also includes a transmission gear 42 with the same number as the driving gear 16, and a positioning circular groove 43 is penetrated at the center of the transmission gear 42, and the inner wall of the positioning circular groove 43 is connected to the rotating shaft 38 The outer wall of the positioning circular groove 43 fits in with each other and the two slide in cooperation; a plurality of slots are provided on the inner wall of the positioning circular groove 43, and the slots slide in cooperation with the blocks provided on the outer wall of the rotating shaft 38; the driving gear 16 is located on the moving path of the transmission gear 42 and the two mesh in cooperation; a limiting base 44 is provided on the top of the transmission gear 42, and a limiting slide post 45 is connected to the side of the limiting base 44, and the limiting slide post 45 slides in cooperation with the limiting base 44; the end of the limiting slide post 45 away from the rotating shaft 38 is connected to the limiting square plate 46; a limiting spring 47 is sleeved on the limiting slide post 45, and one end of the limiting spring 47 is connected to the limiting square plate 46, and the other end is connected to the limiting base 44; the guide slot 39 is located on the moving path of the limiting slide post 45;

[0053] When it is necessary to operate the rotary scraping module to clean the impurities adsorbed on the adsorption bed 2, the limit slide 45 is pulled outward to move within the limit position on the limit base 44, so that the limit spring 47 is in a buffering state, and then the limit slide 45 is moved away from the rotating shaft 38, so that the limit slide 45 is no longer connected to the guide slot 39, thereby releasing the limit setting for the vertical movement of the transmission gear 42, so that the positioning circular groove 43 on it slides within the rotating shaft 38, so that the position of the transmission gear 42 on the rotating shaft 38 can be adjusted, so that the transmission gear 42 is adjusted to a position meshing with the drive gear 16. When it is necessary to operate the shifting locking distance structure to adjust the position of the adsorption bed 2, the drive gear needs to be rotated. 16, so that when it rotates, it will mesh with the transmission gear 42 to rotate. Since the card groove on the positioning circular groove 43 contacts the card block on the outer wall of the rotating shaft 38, the rotating shaft 38 can be driven to rotate, so that the auxiliary gear 41 can rotate quickly under the action of the gear acceleration box 40, so that it can mesh with the rotating gear ring 21 to rotate, so that the rotating scraping module can clean the adsorption bed 2; at the same time, when it is necessary to adjust the synchronous movement of several adsorption beds 2 at the same time, the position of the corresponding transmission gear 42 can be adjusted according to the several adsorption beds 2 that need to be moved synchronously, so that it meshes with the driving gear 16 at the position of the adsorption bed 2 to be adjusted. For example, in the figure, there are the first, second, and third adsorption beds 2 from top to bottom, respectively. Each adsorption bed 2 has a driving gear 16 and a movable transmission gear 42. For example, when the positions of three adsorption beds 2 need to be adjusted synchronously, the three transmission gears 42 are moved to the corresponding driving gears 16, so that the transmission gear 42 and the driving gear 16 at each adsorption bed 2 are meshed. By rotating any one of the driving gears 16, it is meshed with the transmission gear 42 and rotated, thereby driving the other two transmission gears 42 on the rotating shaft 38 to rotate, so that they are meshed with the corresponding driving gear 16 and rotated, so that the displacement screw rod 4 on each adsorption bed 2 is synchronously rotated, thereby driving several adsorption beds 2 to rotate synchronously, reducing the time required for adjusting the adsorption bed 2. , to a certain extent, the time required for adjusting the position of the adsorption bed 2 can be reduced, and the limitations of the desulfurization tower during use can be reduced; the operator can adjust the synchronous movement of different adsorption beds 2 as needed, which can reduce the time for adjusting the position of the adsorption bed 2 and improve the use effect and desulfurization effect of the desulfurization tower; at the same time, when the position of the transmission gear 42 is adjusted, the limit slide 45 is released, so that the limit slide 45 is reset and moved by the reset of the limit spring 47, so that the end close to the rotating shaft 38 enters into any guide slot 39, so that the transmission gear 42 can be limited to the current position, avoiding the transmission gear 42 from shaking or dislocation during use, and improving the use effect of the desulfurization tower.
