Description

Technical Field

[0001] The present invention relates to the technical field of reaction kettles, and more specifically, to an extraction-type titanium-based catalyst preparation catalytic reaction kettle. Background Art

[0002] ‌Titanium-based catalysts‌ refer to catalysts with titanium as the main component, which play an important role in industrial applications. Especially in the selective catalytic reduction (SCR) technology for denitrification treatment, titanium-based catalysts are commonly used in high-temperature and high-pressure reactions (such as olefin polymerization). The reaction kettle can precisely adjust the temperature (heating / cooling system) and pressure (sealing design) to ensure that the catalyst is in the best active state.

[0003] Among them, the patent with the publication number CN213102213U discloses a crystallization reaction system in the preparation process of titanium silicalite molecular sieve catalysts. The crystallization reaction system includes a reaction kettle, a de-alcoholization tower, and a tripropylamine phase separator; a gas phase outlet, a feed inlet, and a tripropylamine discharge outlet are provided at the top of the reaction kettle, a crystallization reaction product discharge outlet is provided at the bottom, and a stirring device and a temperature control device are provided inside; an air inlet is provided on the side wall of the de-alcoholization tower, and the air inlet is connected to the gas phase outlet through a pipeline; the tripropylamine phase separator is provided with a tripropylamine solution inlet and a crude tripropylamine outlet; the tripropylamine solution inlet is connected to the tripropylamine discharge outlet through a pipeline.

[0004] When this structure is in use, the spiral stirring coil fixed on the stirring shaft is used to replace the stirring blades in the traditional stirring device through the stirring device in the reaction kettle. Due to the specific stirring form of the stirring coil and the special liquid flow form generated during the stirring process, the shear force on the crystal grains formed in the reaction kettle can be avoided during the stirring process, which is beneficial to the stable growth of the crystal grains in the reaction kettle. However, the installation angles of the stirring shaft and the stirring coil of this structure are fixed, and it is not easy to eliminate the unmixed area at the bottom of the reaction kettle. The angles of the stirring shaft and the stirring coil are not easy to adjust, and it is easy to generate ineffective flow (such as excessive eddy current or stratification), resulting in increased energy consumption, directly affecting the fluid flow pattern, shear force, and mass transfer efficiency, thereby affecting the reaction results (such as reaction rate, product uniformity, catalyst dispersion, etc.). Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an extraction-type titanium-based catalyst preparation catalytic reaction kettle, aiming to solve the problems proposed in the above background art.

[0006] The present invention provides the following technical solutions: An extraction-type titanium-based catalyst preparation catalytic reaction kettle, including a base, the top of the base is rotatably connected with a reaction kettle body, and a regulation component is arranged on the reaction kettle body; The control component includes a gasket ring arranged at the bottom of the inner cavity of the reactor main body. A column is arranged in the middle of the gasket ring. A central ring is arranged at the top of the column. A plurality of stirring rods are fixedly arranged on the outer side of the central ring. Stirring rings are arranged at the tops of the stirring rods. A plurality of flow dividing rods are distributed at the bottom of the stirring ring; Two support arc plates with adjustable angles are installed at the bottom of the central ring through bolts. The two support arc plates are respectively located on both sides of the column. Regulation grooves are respectively formed through the two support arc plates. Horizontal shafts are arranged in the two regulation grooves. Anti-slip strips are embedded in the top inner walls of the regulation grooves. The horizontal shafts are in contact with the regulation grooves. One end of each horizontal shaft extends to the column and is rotatably connected to the column. The support arc plates and the central ring are detachably connected through bolts. The two support arc plates are respectively located on both sides of the column. An upper support ring is installed at the top end of the stirring ring through bolts. A flow dividing frame is embedded in the upper support ring. The shape of the flow dividing frame is triangular; It can be seen that in the above technical solution, the reactants in the reactor main body can be divided through the spacing between two adjacent flow dividing rods, so that the traction force when the reactants flow through the flow dividing rods rotates the reactants. When the reactants form an axial flow in the middle of the stirring ring, they can contact the flow dividing frame. The axially flowing reactants can be dispersed by being blocked by the flow dividing frame and are easily dispersed to the outside of the stirring ring. The first motor drives the horizontal shaft to rotate. When the horizontal shaft rotates, it frictions with the regulation groove. Then the support arc plate can drive the structures on the stirring ring, the flow dividing rods and the upper support ring to adjust the angle on the column, so as to increase the shear force during the radial flow, break the internal structure of the high-viscosity fluid, accelerate the mixing of the reactants, effectively eliminate the unmixed area at the bottom of the reactor main body. After the reactants are mixed, the reactor main body heats the mixed reactants. The reacted materials are discharged through the guide cylinder at the bottom of the base for subsequent processes; Two ends of the two horizontal shafts facing the column are sleeved with contact cylinders. The contact cylinders are in contact with one side of the support arc plate. One end of one of the horizontal shafts is provided with a first motor for driving the horizontal shaft to rotate. The first motor is installed on the outer side of the reactor main body through bolts. The two horizontal shafts are coaxially and fixedly connected. The end of the horizontal shaft away from the first motor extends to the reactor main body and is rotatably connected to the reactor main body. A support frame is fixedly arranged in the middle of the gasket ring. The bottom end of the column extends to the support frame and is detachably connected to the support frame through bolts. A first gear is installed on the outer side of the reactor main body through bolts. A second gear is arranged on the outer side of the first gear. The second gear meshes with the first gear. A second motor for driving the second gear to rotate is installed at the bottom of the base through bolts; It can be seen that in the above technical solution, the second gear is meshed with the first gear, so that when the second gear rotates, it drives the first gear to rotate, and the first gear drives the reactor body and the gasket ring to rotate on the base, and the gasket ring can drive the support frame and the column to rotate when rotating. Since each horizontal axis passes through the supporting arc plate and is installed on the column, and the abutment cylinder can abut on the side of the supporting arc plate, then when the horizontal axis rotates along the axial direction of the gasket ring, it can drive the supporting arc plate, the center ring, the stirring rod and each structure on the stirring ring to rotate, and first stir the raw materials in the reactor body; A plurality of guide rings are arranged in the middle of the stirring ring, and the plurality of guide rings are stacked from small to large, and a positioning ring is fixedly arranged on the top of the topmost guide ring, and a plurality of rotating drums are movably connected to the positioning ring, and the plurality of guide rings are connected by elastic ribs, and a cover plate is hinged on the top of the reactor body, and a guide drum is installed at the bottom of the cover plate and the base through a valve; It can be seen that in the above technical solution, the guide ring is compressed by the resistance of the reactants to stretch the elastic ribs on each guide ring, thereby adjusting the position of each guide ring, so that the guide ring can be reset when the resistance between the guide ring and the reactants is small, and can be stretched when the resistance between the guide ring and the reactants is large, thereby realizing the function of automatically adjusting the spacing of the guide ring in the middle of the stirring ring along the axial direction of the stirring ring, which is easy to quickly disperse the reactants, so that the reactants form an axial flow to promote uniform dispersion of the catalyst particles and avoid agglomeration leading to uneven polymerization degree.

[0007] Technical effects and advantages of the present invention: 1. The present invention enables the reactants in the reactor body to be diverted through the spacing between two adjacent diverter rods, so that the reactants flow through the two diverter rods due to the traction force when the diverter rods rotate. At the same time, during the process of the diverter rods, the stirring ring and the stirring rod rotating to stir the reactants, the guide ring is pressed by the resistance of the reactants to stretch the elastic ribs on each guide ring, thereby adjusting the position of each guide ring. When the resistance between the guide ring and the reactants is small, the guide ring can be reset, and when the resistance between the guide ring and the reactants is large, the guide ring can be stretched, thereby realizing the function of automatically adjusting the spacing of the guide ring in the middle of the stirring ring along the axial direction of the stirring ring, making it easy to quickly disperse the reactants, so that the reactants form an axial flow to promote uniform dispersion of catalyst particles and avoid agglomeration leading to uneven polymerization degree; 2. When the reactants of the present invention form an axial flow in the middle of the stirring ring through the guide ring, they can contact the diverter frame, so that the reactants flowing in the axial direction can be dispersed due to the isolation of the diverter frame and easily dispersed to the outside of the stirring ring; 3. The present invention can drive various structures on the stirring ring, the flow dividing rod and the upper supporting ring to adjust the angle on the column through the supporting arc plate, so as to increase the shear force during the radial flow, break the internal structure of the high-viscosity fluid, accelerate the mixing of reactants, and effectively eliminate the unmixed area at the bottom of the reaction kettle body; 4. When the horizontal axis rotates and rubs against the control groove in the present invention, the anti-slip strips embedded in the control groove increase the friction force between the control groove and the horizontal axis to ensure the stability of the supporting arc plate during the deflection adjustment at the top of the column. At the same time, by stirring the reactants in the axial flow and the longitudinal flow synchronously, it is easy for the reactant particles to be evenly dispersed, which can promote the contact between the catalyst and the reactants, is not easy to generate ineffective flow, and shortens the reaction time; In summary, through the corresponding cooperation of each structure, when the resistance of the flow guiding ring in contact with the reactants is small, the flow guiding ring can reset, and when the resistance of the flow guiding ring in contact with the reactants is large, it can stretch, realizing the function of automatically adjusting the distance along the axial direction of the stirring ring in the middle of the stirring ring. It is easy to quickly disperse the reactants, make the reactants form an axial flow to promote the uniform dispersion of catalyst particles, avoid agglomeration resulting in uneven degree of polymerization. Through the supporting arc plate, various structures on the stirring ring, the flow dividing rod and the upper supporting ring can be driven to adjust the angle on the column, so as to increase the shear force during the radial flow, break the internal structure of the high-viscosity fluid, accelerate the mixing of reactants, and effectively eliminate the unmixed area at the bottom of the reaction kettle body. By stirring the reactants in the axial flow and the longitudinal flow synchronously, it is easy for the reactant particles to be evenly dispersed, which can promote the contact between the catalyst and the reactants, is not easy to generate ineffective flow, and shortens the reaction time.

DETAILED DESCRIPTION

[0019] like Figures 1-8 The extractive titanium catalyst preparation catalytic reactor shown in the figure, through the regulating component arranged on the base 1, makes the reactants realize axial flow and longitudinal flow synchronously stirred, so that the reactant particles are easily dispersed evenly, the contact between the catalyst and the reactants can be promoted, and it is not easy to generate invalid flow, and the reaction time is shortened. The specific structural arrangement of the component is as follows; The regulating component includes a gasket 3 arranged at the bottom of the inner cavity of the reactor body 2, a column 4 is arranged in the middle of the gasket 3, a center ring 5 is arranged on the top of the column 4, a plurality of stirring rods 6 are fixedly arranged on the outside of the center ring 5, and a stirring ring 7 is arranged on the top of each stirring rod 6, and a plurality of diverter rods 8 are distributed at the bottom of the stirring ring 7; At the bottom of the central ring 5, two support arc plates 9 with adjustable angles are installed by bolts. The two support arc plates 9 are respectively located on both sides of the column 4, and a control groove 10 is penetrated through each support arc plate 9. A horizontal shaft 11 is arranged in each of the two control grooves 10, and an anti-slip strip is embedded in the top of the inner wall of the control groove 10. The horizontal shaft 11 is in contact with the control groove 10, and one end of each horizontal shaft 11 extends to the column 4 and is rotatably connected to the column 4. The support arc plate 9 and the central ring 5 are detachably connected by bolts, and the support arc plates 9 are respectively located on both sides of the column 4. At the top end of the stirring ring 7, a upper support ring 18 is installed by bolts. A flow dividing frame 19 is embedded in the upper support ring 18, and the shape of the flow dividing frame 19 is triangular; A contact cylinder 12 is sleeved on one end of each of the two horizontal shafts 11 facing the column 4. The contact cylinder 12 abuts against one side of the support arc plate 9, and a first motor 13 for driving the horizontal shaft 11 to rotate is arranged at one end of one of the horizontal shafts 11. The first motor 13 is installed on the outside of the reaction kettle body 2 by bolts, and the two horizontal shafts 11 are coaxially and fixedly connected. The end of the horizontal shaft 11 away from the first motor 13 extends to the reaction kettle body 2 and is rotatably connected to the reaction kettle body 2. A support frame 14 is fixedly arranged in the middle of the cushion ring 3. The bottom end of the column 4 extends to the support frame 14 and is detachably connected to the support frame 14 by bolts. A first gear 15 is installed on the outside of the reaction kettle body 2 by bolts. A second gear 16 is arranged on the outside of the first gear 15. The second gear 16 meshes with the first gear 15. A second motor 17 for driving the second gear 16 to rotate is installed at the bottom of the base 1 by bolts; A plurality of flow guiding rings 20 are arranged in the middle of the stirring ring 7. The plurality of flow guiding rings 20 are stacked from small to large, and a positioning ring 21 is fixedly arranged at the top of the topmost flow guiding ring 20. A plurality of rotating cylinders 22 are movably connected to the positioning ring 21. The plurality of flow guiding rings 20 are all connected by elastic ribs. A cover plate 23 is hinged to the top of the reaction kettle body 2. A material guiding cylinder 24 is installed at the bottom of the cover plate 23 and the base 1 through a valve.

[0020] The specific working principle is as follows. When preparing the catalyst, the reactants are fed into the reaction kettle through the material guiding cylinder 24 at the top of the cover plate 23. The second motor 17 is started to drive the second gear 16. The second gear 16 meshes with the first gear 15, so that when the second gear 16 rotates, it drives the first gear 15 to rotate, and the first gear 15 drives the reaction kettle body 2 and the cushion ring 3 to rotate on the base 1; When the cushion ring 3 rotates, it can drive the support frame 14 and the column 4 to rotate. Since each horizontal shaft 11 penetrates through the support arc plate 9 and is installed on the column 4, and the contact cylinder 12 abuts against the side of the support arc plate 9, when the horizontal shaft 11 rotates along the axial direction of the cushion ring 3, it can drive the support arc plate 9, the central ring 5, the stirring rod 6 and each structure on the stirring ring 7 to rotate, and first stir the raw materials in the reaction kettle body 2.

[0021] During the stirring process of the reactants, the reactants in the main body 2 of the reaction kettle can be shunted through the spacing between two adjacent shunt rods 8, so that the reactants flow through the two shunt rods 8 under the traction force when the shunt rods 8 rotate. At the same time, during the process of the shunt rods 8, the stirring ring 7 and the stirring rods 6 rotate to stir the reactants, the guide rings 20 can stretch the elastic ribs on each guide ring 20 due to the oppression of the reactant resistance, and then adjust the positions of the respective guide rings 20. When the resistance of the guide ring 20 in contact with the reactants is small, the guide ring 20 can reset, and when the resistance of the guide ring 20 in contact with the reactants is large, it can stretch, realizing the function of automatically adjusting the spacing along the axial direction of the stirring ring 7 in the middle of the stirring ring 7 for the guide ring 20, which is conducive to quickly dispersing the reactants, making the reactants form an axial flow to promote the uniform dispersion of catalyst particles, avoiding uneven polymerization degree caused by agglomeration, and when the reactants form an axial flow in the middle of the stirring ring 7, they can contact the shunt frame 19, so that the axially flowing reactants can be dispersed by being blocked by the shunt frame 19, and are easily dispersed to the outside of the stirring ring 7.

[0022] At the same time, in order to further ensure the mixing effect of the reactants, the first motor 13 drives the horizontal shaft 11 to rotate. When the horizontal shaft 11 rotates, it rubs against the control groove 10, and then the support arc plate 9 can drive the various structures on the stirring ring 7, the shunt rods 8 and the upper support ring 18 to adjust the angle on the column 4, realizing an increase in the shear force during the radial flow, breaking the internal structure of the high-viscosity fluid, accelerating the mixing of the reactants, effectively eliminating the unmixed area at the bottom of the main body 2 of the reaction kettle. After the reactants are mixed, the main body 2 of the reaction kettle heats the mixed reactants, and the reacted material is discharged through the guide cylinder 24 at the bottom of the base 1 for subsequent processes; And when the horizontal shaft 11 rotates and rubs against the control groove 10, the anti-slip strips embedded in the control groove 10 increase the friction between the control groove 10 and the horizontal shaft 11 to ensure the stability of the support arc plate 9 when deflecting and adjusting at the top of the column 4.

[0023] Specifically, refer to the attached Figure 5 and 6 , the anti-slip strips and the support arc plate 9 are detachable structures. The anti-slip strips can be disassembled and replaced with racks, and gears can be installed on the horizontal shaft 11. The support arc plate 9 is driven to deflect by the meshing of the gears and the racks, which can effectively ensure the stability of the support arc plate 9 when deflecting and adjusting.

[0024] At the same time, by stirring the reactants synchronously in the axial flow and the longitudinal flow, it is easy to uniformly disperse the reactant particles, promote the contact between the catalyst and the reactants, is not prone to generate ineffective flow, and shortens the reaction time.

[0025] Different from the prior art, the present application discloses an extraction-type titanium-based catalyst preparation catalytic reactor. By stirring the reactants in a synchronous manner with axial flow and longitudinal flow, it is easy to uniformly disperse the reactant particles, promote the contact between the catalyst and the reactants, not easy to generate ineffective flow, and shorten the reaction time.

[0026] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
