Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of catalyst production, in particular to a chemical catalyst production device. BACKGROUND

[0002] Hydrogenation catalyst refers to the catalyst used when a compound is added to hydrogen. A large amount of flue gas containing nitrogen oxides is generated during the production of hydrogenation catalysts. In order to prevent environmental pollution, the flue gas generated during the production of hydrogenation catalysts needs to be treated using a special tail gas denitration reactor to remove as much nitrogen oxides in the flue gas as possible.

[0003] For example, the Chinese patent with publication number CN118217782B discloses a tail gas denitration reactor for hydrogenation catalyst production, which comprises a reactor body and a nitrogen injection structure and a rectifier installed on the reactor body. A dust collecting hopper is installed at the bottom of the reactor body gas inlet. A plurality of catalyst boxes are connected to one end of the reactor body inside near the gas outlet. The inside of the catalyst box is filled with catalyst particles. Heat absorption pipes are provided between each layer of catalyst boxes. A beating assembly is provided on one side of the heat absorption pipe. A steam water pump is provided at the outlet end of the heat absorption pipe and is fixed to the outer wall of the reactor body. The water inlet of the steam water pump is connected to the heat absorption pipe. The catalyst box position is cooled by the heat absorption pipe to avoid high temperature near the catalyst box, which causes the catalyst particles to be deactivated, thereby affecting the treatment efficiency of the reactor body for nitrogen oxides.

[0004] The above-mentioned heat absorption pipe, steam water pump, output pipe, input pipe and steam injection pipe are used to transfer the high temperature inside the catalyst box to the outside and gradually cool down the temperature around the catalyst box, but during the cooling process, the cooling water in the heat absorption pipe flows to drive the rotating blades, which in turn drives the elastic beating pieces to rotate and beat on the outer wall of the catalyst box. During the beating process, noise is generated by the contact between the two, and resistance is generated when the elastic beating pieces contact the catalyst box, which reduces the rotation speed of the elastic beating pieces and affects the shaking effect of the catalyst box, resulting in the agglomeration of catalyst particles in the catalyst box. Therefore, the present application provides a chemical catalyst production device to meet the needs. SUMMARY

[0017] Compared with the prior art, the present application has at least the following beneficial effects:

[0018] In the above scheme, by arranging the vibration assembly, the irregular shaking of the second universal ball on the vibration assembly is driven by the flow of cooling water in the process of normal cooling of the cooling pipe, the catalyst box is touched and lifted upward, the position state of the catalyst box is changed, the vibration of the catalyst box occurs, the caking between catalyst particles is reduced, since the second universal ball is a spherical body, more point contact is formed when the second universal ball contacts the bottom of the catalyst box, the rotation and beating are changed into point contact beating, so that the torque required in the vibration process of the catalyst box can be reduced, the noise generated by contact can be reduced, and the vibration effect of the catalyst box can be improved.

[0019] By setting the first universal ball, friction inclined plate and lifting block, the normal stable state of the catalyst box is ensured by using the self-weight of the catalyst box and the mutual resistance of the first universal ball when the catalyst box is placed, and when the catalyst box is shaken by external force, it will not be separated under the action of the first universal ball and the lifting block, and the friction inclined plate increases the friction between the upper and lower catalyst boxes, so that it will be limited in a small range during shaking, further ensuring that the catalyst box is within the specified range during shaking, and improving the shaking effect of the catalyst box.

[0020] By setting the floating ball, floating column and movable tray, the floating ball and floating column will shake during continuous flow of cooling water, and when the floating ball and floating column are unstable and shake, they will drive the supporting tray and movable tray, and then cause the second universal ball to irregularly contact the bottom of the catalyst box. When contacting, the friction on the outer wall of the second universal ball will further increase the friction between the second universal ball and the bottom of the catalyst box, thereby increasing the shaking effect of the catalyst box and further improving the displacement between the catalyst particles in the catalyst box, reducing the agglomeration between the catalysts.

[0021] By setting the fixed frame, weakening part and limiting cover, when the second universal ball is moved upward and shaken by the cooling water, it can be ensured that the second universal ball can contact the bottom of the catalyst box to the greatest extent, avoiding the situation that the second universal ball cannot contact the bottom of the catalyst box due to violent shaking and causing uneven local stress. The fixed frame and weakening part connected to the outside of each limiting disc can also improve the synchronicity of the second universal ball during the rising process, reduce the different acting forces caused by the different rising heights and shaking degrees between the second universal balls, thereby causing different resistance forces of the catalyst box and affecting the shaking of the catalyst box.

[0044] As Figures 1 to 13As shown, an embodiment of the present invention provides a chemical catalyst production apparatus, including a denitrification reactor body 1, a steam pump 2, a cooling pipe 3, a reaction chamber 4, and a catalyst box 5. A limiting platform 6 is installed on the surface of the catalyst box 5, a reinforcing block 7 is snapped onto the top of the limiting platform 6, a first universal ball 9 is installed on the top of the limiting platform 6, and a liner tray 10 is installed on the top of the cooling pipe 3. A vibration assembly is used to catalytically shake the catalyst box 5. The vibration assembly is connected to the cooling pipe 3. An adapter groove is opened on the outer wall of the limiting platform 6 near the first universal ball 9, and a lightweight circular groove is opened in the middle of the limiting platform 6. The lower part of the first universal ball 9 is snapped onto the top of the limiting platform 6. The liner trays 10 are arrayed on the outer wall of the cooling pipe 3. The denitrification reactor body 1, steam pump 2, cooling pipe 3, reaction chamber 4, and catalyst box 5 are existing structures. Since the existing structures are not related to the core technical solution of this application, they will not be described in detail.

[0045] By setting up a vibration assembly, during the normal cooling process of the cooling pipe 3, the flow of cooling water drives the irregular shaking of the second universal ball 24 on the vibration assembly, which touches and lifts the catalyst box 5, changing the position of the catalyst box 5, thus causing the catalyst box 5 to vibrate. This reduces the agglomeration between catalyst particles. Since the second universal ball 24 is a spherical body, it makes more point contact when it contacts the bottom of the catalyst box 5. This changes the rotational tapping to point contact tapping, thereby reducing the torque required for the catalyst box 5 to vibrate, reducing the noise generated by the contact, and improving the vibration effect of the catalyst box 5.

[0046] like Figures 6 to 10 As shown, a sliding part 8 is fixedly connected to the outer wall of the reinforcing block 7. A friction inclined plate 11 is attached to the top of the reinforcing block 7 near the sliding part 8. A lifting block 12 is fixedly connected to the top of the limiting platform 6. A second protective block is fixedly connected to the top of the lifting block 12. A first connecting post 13 is fixedly connected between the second protective blocks. A fixing post 14 is fixedly connected to the outer wall of the second protective block. The sliding part 8 is fixedly connected to the upper and lower ends of the reinforcing block 7 respectively. The sliding part 8 is slidably connected to the outer wall of the limiting platform 6. A friction groove is opened on the top of the friction inclined plate 11. The fixing post 14 is fixedly connected to the outer wall of the limiting platform 6.

[0047] By the above structure, inside the reaction box 4 will be often placed a plurality of groups of catalyst boxes 5, the direction of placement is vertical, from bottom to top, when placing the catalyst boxes 5, except for the bottommost catalyst box 5, the remaining catalyst boxes 5 need to be placed with a limiting table 6 below, the bottom of the limiting table 6 is clamped and fixed on the top of the previous catalyst box 5, the height of the limiting table 6 is roughly consistent with the thickness of the cooling pipe 3, the limiting table 6 will not affect the normal use of the cooling pipe 3 when placed, then a reinforcing block 7 is clamped and slid on the top of the limiting table 6, the overall size of the reinforcing block 7 is consistent with the size of the gap on the top of the limiting table 6, the reinforcing block 7 is horizontally clamped and slid in the gap on the top of the limiting table 6, until the end of the reinforcing block 7 touches the inner wall of the limiting table 6, indicating that the reinforcing block 7 is completely clamped on the top of the limiting table 6, at this time the friction inclined plate 11 is clamped and placed on the side of the sliding part 8, the top of the reinforcing block 7 cooperates with the friction inclined plate 11 to form a horizontal plane, by default, the first universal ball 9 is an integral structure with the limiting table 6, and the lifting block 12, the first connecting column 13 and the fixed column 14 are auxiliary parts around the first universal ball 9, which are also integral structures with the limiting table 6, when placing the upper catalyst box 5, it is necessary to ensure that the adaptive slot on the bottom of the upper catalyst box 5 is in close contact with the first universal ball 9, the fixed column 14 corresponds to the hole on the bottom of the upper catalyst box 5 one by one, so that the gap between the bottom of the upper catalyst box 5 and the sliding part 8 will be small, and the bottom of the upper catalyst box 5 is in close contact with the top of the friction inclined plate 11, limiting tables 6 are placed at the four corners of the catalyst box 5, so that the state of the catalyst box 5 changes from fixed to semi-fixed, and shaking may occur when subjected to external force, the catalyst box 5 needs five layers in total, and the catalyst box 5 is placed and stabilized in turn by using the above method, the inner wall size of the reaction box 4 is slightly larger than the size of the catalyst box 5, on the one hand, it is convenient for taking and replacing the catalyst box 5, and on the other hand, the shaking of the catalyst box 5 will not be restricted during work, ensuring the normal vibration and shaking of the catalyst box 5.

[0048] By setting the first universal ball 9, the friction inclined plate 11 and the lifting block 12, the normal stable state of the catalyst box 5 is ensured by using the self-weight of the catalyst box 5 and the mutual contact of the first universal ball 9 when placing the catalyst box 5, and when the catalyst box 5 shakes due to external impact during work, it will not be separated under the action of the first universal ball 9 and the lifting block 12, and the friction inclined plate 11 increases the friction between the upper and lower catalyst boxes 5, so that the catalyst box 5 will be limited in a small range during shaking, further ensuring that the catalyst box 5 is within the specified range when shaking, and improving the shaking effect of the catalyst box 5.

[0049] As Figure 11 and Figure 12As shown, the vibration assembly comprises a protective shell 18 fixedly connected to the top of the cooling pipe 3, the bottom of the protective shell 18 is fixedly connected with a frame body 17, the bottom of the frame body 17 is fixedly connected with a floating ball 15 and a floating column 16, the inner wall of the protective shell 18 is slidably connected with a movable tray 21, the top of the movable tray 21 is fixedly connected with a first protective block, the first protective blocks are fixedly connected with a second connecting column 22, the top of the first protective block is matched with a limiting disc 23, the inner wall of the limiting disc 23 and the first protective block is matched with a second universal ball 24, the protective shell 18 is composed of two parts, the upper part is a deformation end, the lower part is a fixed end, the floating ball 15 is located below the floating column 16, the middle positions of the floating ball 15 and the floating column 16 are fixedly connected to the outer wall of the bottom of the frame body 17, the bottom of the movable tray 21 is fixedly connected to the middle position of the top of the supporting tray 10, the area surrounded by the first protective block is larger than the outer wall size of the second universal ball 24, and a friction strip is arranged on the top of the second universal ball 24.

[0050] Through the above structure, after placing a layer of catalyst box 5, the contact between the upper catalyst box 5 and the second universal ball 24 is observed, and in the above, when the first universal ball 9 is aligned with the bottom of the catalyst box 5, the alignment of the second universal ball 24 with the bottom of the catalyst box 5 also needs to be observed, when the upper catalyst box 5 is not placed, the first universal ball 9 is installed on the top of the limiting table 6, and the second universal ball 24 is installed on the inner wall of the limiting disc 23, when it is ensured that the upper catalyst box 5 is placed stably, it can be found that the second universal ball 24 moves downward under the weight of the upper catalyst box 5, and the second universal ball 24 is clamped on the inner wall of the limiting disc 23, causing the limiting disc 23, the second connecting column 22, the movable tray 21 and the supporting tray 10 to move downward, since the upper half of the protective shell 18 is fixedly connected to the outer wall of the movable tray 21, the upper half of the protective shell 18 will also be deformed, while the floating ball 15, the floating column 16 and the frame body 17 are always inside the cooling pipe 3, the materials of the floating ball 15 and the floating column 16 are plastic, in work, the floating ball 15 and the floating column 16 use the combined buoyancy to push the supporting tray 10 upward, and the upward movement of the supporting tray 10 drives the movable tray 21, the second connecting column 22, the limiting disc 23 and the second universal ball 24 to move upward, so that the top of the second universal ball 24 abuts against the bottom of the catalyst box 5, and the catalyst box 5 is pushed upward, so that the catalyst box 5 appears to be shaking, in order to improve the shaking ability of the catalyst box 5, when the second universal ball 24 is pushed upward, the friction strip on the outer wall of the second universal ball 24 can better contact the bottom of the catalyst box 5, in order to avoid the falling of the second universal ball 24 during movement, a second protective block is arranged on the top of the movable tray 21, and the second connecting column 22 is used to strengthen, so as to improve the protection and limiting of the second universal ball 24.

[0051] By setting the floating ball 15, the floating column 16 and the movable tray 21, the floating ball 15 and the floating column 16 will sway in the process of the continuous flow of cooling water, and when the floating ball 15 and the floating column 16 sway unstably, the supporting tray 10 and the movable tray 21 will be driven, and then the second universal ball 24 will irregularly contact the bottom of the catalyst box 5, at the time of contact, the friction on the outer wall of the second universal ball 24 will further improve the friction between the second universal ball 24 and the bottom of the catalyst box 5, thereby increasing the effect of the catalyst box 5 swaying, further improving the displacement between the catalyst particles in the catalyst box 5, and reducing the caking between the catalysts.

[0052] As shown in Figure 13 The outer wall of the limiting disc 23 is fixedly connected with a fixed frame 27, the fixed frame 27 is close to the outer wall of the limiting disc 23 and is provided with a weakening portion 28, the end of the fixed frame 27 close to the weakening portion 28 is fixedly connected with an annular frame 19, the inner wall of the annular frame 19 is fixedly connected with a plurality of connecting portions 26, the end of the connecting portion 26 is fixedly connected with a fixed disc 20, the bottom of the fixed disc 20 is fixedly connected with a limiting cover 25, the fixed frame 27 is a large-opening "U" type, the end of the fixed frame 27 is fixedly connected with the outer wall of the connecting portion 26, the fixed frame 27 and the limiting disc 23 are fixedly connected with a connecting column, the weakening portion 28 is arranged on the outer wall of the connecting column, a plurality of threaded columns are circumferentially arranged on the fixed disc 20, a circular groove is arranged at the middle position of the fixed disc 20, and the limiting cover 25 is surrounded and has a size greater than that of the second universal ball 24.

[0053] By the above structure, in the process of contacting the second universal ball 24 with the bottom of the catalyst box 5, the fixed frame 27 can be used to connect each second universal ball 24, and the fixed disc 20 and the limiting cover 25 are arranged around the bottom of the catalyst box 5 near the notch of the second universal ball 24. The limiting cover 25 is used to protect and limit the second universal ball 24 from the top, which does not affect the contact between the second universal ball 24 and the bottom of the catalyst box 5, and blocks the surrounding of the second universal ball 24. On the one hand, it avoids the instability of the cooling water flow causing the second universal ball 24 to tilt or fall off when contacting the bottom of the catalyst box 5. On the other hand, the slot hole in the middle position of the fixed disc 20 can also limit the contact range between the second universal ball 24 and the bottom of the catalyst box 5, ensuring that the shaking of the second universal ball 24 can directly and effectively act on the bottom of the catalyst box 5, reducing the situation that the second universal ball 24 cannot effectively contact the bottom of the catalyst box 5 due to intense reaction after shaking. The weakening part 28 is provided on the column between the fixed frame 27 and the limiting disc 23, which can move upward without being limited by the fixed frame 27, limiting the tilting direction of the second universal ball 24 during the upward movement, avoiding the phenomenon of tilting upward. During the upward movement of the second universal ball 24, it will contact the inner wall of the limiting cover 25 until the friction strip at the top of the second universal ball 24 passes through the middle position of the fixed disc 20 and contacts the bottom of the catalyst box 5. At the same time, the weakening part 28 can make the second universal ball 24 have a certain connection, without affecting the normal upward movement and resistance of the second universal ball 24.

[0054] It is worth mentioning that the entire vibration assembly is longitudinally and transversely arrayed on the cooling pipe 3 in the horizontal plane, the top of the vibration assembly contacts the bottom of the catalyst box 5, and the bottom of the vibration assembly is fixed on the outer wall of the cooling pipe 3. By using the resistance and buoyancy in the cooling water flow process, the lifting position of the second universal ball 24 inside the vibration assembly is changed, and the second universal ball 24 is subjected to up-and-down reciprocating motion. Specifically, after the top of the second universal ball 24 contacts the bottom of the catalyst box 5, the second universal ball 24 will move downward due to the interaction. The floating ball 15 and the floating column 16 will shake and rise due to the buoyancy and resistance after encountering the cooling water, and will drive the second universal ball 24 to start moving upward again. Such a cycle is repeated, and the second universal ball 24 continuously contacts the catalyst box 5 to achieve the vibration effect.

[0055] Further, since each layer of the catalyst box 5 is not fixed when placed, but will shake under the action of external force, the shaking effect of the catalyst box 5 will be more obvious under the action of several second universal balls 24. The presence of the fixed frame 27 and the weakening part 28 can ensure that each second universal ball 24 will remain consistent as much as possible during the shaking process, reducing the mutual resistance and force leakage between each second universal ball 24.

[0056] By setting the fixing frame 27, the weakened part 28 and the limiting cover 25, when the second universal ball 24 is moved upward and shaken by the cooling water, it can be ensured that the second universal ball 24 can be in contact with the bottom of the catalyst box 5 to the greatest extent, avoiding the situation that the second universal ball 24 cannot be in contact with the bottom of the catalyst box 5 due to severe shaking, and the local stress is uneven, and the fixing frame 27 and the weakened part 28 connected on the outside of each limiting disc 23 can also improve the synchronism of the second universal ball 24 in the rising process, reduce the different forces caused by the different rising heights and shaking degrees between the second universal balls 24, and thus cause different resistance to the catalyst box 5, and affect the shaking of the catalyst box 5.

[0057] The working principle of the technical scheme provided by the application is as follows:

[0058] In the inside of the reaction box 4, there are often multiple groups of catalyst boxes 5 placed vertically, and when placing the catalyst boxes 5 from bottom to top, except for the bottommost catalyst box 5, the remaining catalyst boxes 5 need to be placed on the limiting table 6 below, and the bottom of the limiting table 6 is clamped and fixed on the top of the previous catalyst box 5. The height of the limiting table 6 is approximately consistent with the thickness of the cooling pipe 3, and the placement of the limiting table 6 will not affect the normal use of the cooling pipe 3. Then a reinforcing block 7 is clamped and slid on the top of the limiting table 6, and the overall size of the reinforcing block 7 is consistent with the size of the gap on the top of the limiting table 6. The reinforcing block 7 is horizontally slid and clamped in the gap on the top of the limiting table 6 until the end of the reinforcing block 7 touches the inner wall of the limiting table 6, indicating that the reinforcing block 7 is completely clamped on the top of the limiting table 6. At this time, the friction inclined plate 11 is clamped and placed on the side of the sliding part 8, and the top of the reinforcing block 7 cooperates with the friction inclined plate 11 to form a horizontal plane. By default, the first universal ball 9 is an integrated structure with the limiting table 6, and the lifting block 12, the first connecting column 13 and the fixed column 14 are auxiliary parts around the first universal ball 9, which are also integrated with the limiting table 6. When placing the upper catalyst box 5, it is necessary to ensure that the adaptive groove on the bottom of the upper catalyst box 5 is in close contact with the first universal ball 9, and the fixed column 14 corresponds to the hole in the bottom of the upper catalyst box 5 one by one. In this way, the gap between the bottom of the upper catalyst box 5 and the sliding part 8 will be very small, and the bottom of the upper catalyst box 5 and the top of the friction inclined plate 11 will be in close contact. The limiting table 6 is placed at the four corners of the catalyst box 5, so that the state of the catalyst box 5 changes from fixed to semi-fixed, and shaking occurs when an external force is applied. The catalyst box 5 needs five layers in total, and the above method is used to place and stabilize the catalyst box 5. The inner wall size of the reaction box 4 is slightly larger than the size of the catalyst box 5, on the one hand, it is convenient for taking and replacing the catalyst box 5, and on the other hand, the shaking of the catalyst box 5 will not be restricted during work, ensuring the normal vibration and shaking of the catalyst box 5.

[0059] After placing a layer of catalyst box 5, the contact between the upper catalyst box 5 and the second universal ball 24 is observed, and when the first universal ball 9 is aligned with the bottom of the catalyst box 5 as described above, the alignment of the second universal ball 24 with the bottom of the catalyst box 5 is also observed. When the upper catalyst box 5 is not placed, the first universal ball 9 is installed on the top of the limiting table 6, and the second universal ball 24 is installed on the inner wall of the limiting disc 23. When it is ensured that the upper catalyst box 5 is placed stably, it can be found that the second universal ball 24 moves downward under the weight of the upper catalyst box 5, and the second universal ball 24 is clamped on the inner wall of the limiting disc 23, causing the limiting disc 23, the second connecting column 22, the movable tray 21 and the supporting tray 10 to move downward. Since the upper half of the protective shell 18 is fixed on the outer wall of the movable tray 21, the upper half of the protective shell 18 will also deform. The floating ball 15, the floating column 16 and the frame 17 are always inside the cooling pipe 3. The material of the floating ball 15 and the floating column 16 is plastic. In work, the floating ball 15 and the floating column 16 use the buoyancy together to push the supporting tray 10 upward, and the upward movement of the supporting tray 10 drives the movable tray 21, the second connecting column 22, the limiting disc 23 and the second universal ball 24 to move upward, so that the top of the second universal ball 24 touches the bottom of the catalyst box 5, and the catalyst box 5 is pushed upward, causing the catalyst box 5 to shake. In order to improve the shaking ability of the catalyst box 5, the friction strip on the outer wall of the second universal ball 24 can better contact the bottom of the catalyst box 5 when the second universal ball 24 is pushed upward. In order to avoid the falling of the second universal ball 24 during movement, a second protective block is arranged on the top of the movable tray 21, and the second connecting column 22 is used to strengthen, so as to improve the protection and limiting of the second universal ball 24.

[0060] In the process of contacting the second universal ball 24 with the bottom of the catalyst box 5, the fixed frame 27 can be used to connect each second universal ball 24, and the fixed disc 20 and the limiting cover 25 are arranged around the slot of the second universal ball 24 on the bottom of the catalyst box 5, the limiting cover 25 is used to protect and limit the second universal ball 24 from the top, which can block the surrounding of the second universal ball 24 without affecting the contact between the second universal ball 24 and the bottom of the catalyst box 5, on the one hand, the instability of the cooling water flow can cause the second universal ball 24 to tilt or fall off when contacting the bottom of the catalyst box 5, on the other hand, the slot in the middle of the fixed disc 20 can also limit the contact range of the second universal ball 24 with the bottom of the catalyst box 5, which can ensure that the shaking of the second universal ball 24 can directly and effectively act on the bottom of the catalyst box 5, and reduce the situation that the second universal ball 24 cannot effectively contact the bottom of the catalyst box 5 due to violent reaction after shaking, and the weakening part 28 on the column between the fixed frame 27 and the limiting disc 23 can also move upwards without being limited by the fixed frame 27, which can limit the tilting direction of the second universal ball 24 during the upward process, avoid the phenomenon of tilting upwards, and the second universal ball 24 will contact the inner wall of the limiting cover 25 during the upward process, until the friction strip on the top of the second universal ball 24 passes through the middle position of the fixed disc 20 and contacts the bottom of the catalyst box 5, and the weakening part 28 can make the second universal ball 24 have a certain connection, and will not affect the normal upward and resistance of the second universal ball 24.
