Description

Technical Field

[0001] The present invention relates to the technical field of catalytic reactions, in particular to a glass-lined tube type continuous flow reaction device. Background Art

[0002] Reactors are widely used in the petroleum, chemical, rubber, pesticide, dye, pharmaceutical, and food industries. Reactors are comprehensive reaction vessels whose structure, functions, and accessories are designed based on reaction conditions. From feeding to reaction to discharging, pre-set reaction steps can be completed with a high degree of automation, ensuring strict control of key parameters such as temperature, pressure, mechanical control (stirring, air blast, etc.), and reactant and product concentrations. Their structure generally consists of a reactor body, transmission mechanism, stirring mechanism, heating mechanism, cooling mechanism, and sealing mechanism.

[0003] The Chinese patent with the announcement number CN118949859B discloses a reactor with a catalyst turbulence temperature control structure, including a reactor, an agitator installed on the reactor, and a heating pipe arranged in the reactor. The heating pipe is coiled to form a spoiler and fixedly connected to the inner wall of the reactor. A fixed bed is detachably connected to the heating pipe. The surface of the fixed bed is set as a mesh surface, and the fixed bed is filled with a catalyst. The particle size of the catalyst is smaller than the mesh aperture of the mesh surface. The fixed bed is located in the direction of the material flow facing or facing away from the heating pipe.

[0004] In the above technical solution, when the fixed bed is located in the direction of the material flow facing the heating pipe, the material can form a certain flushing effect on the catalyst, and the material will be slowed down after passing through the fixed bed, with a certain reaction time, and then flow from the side of the heating pipe, at this time it can form turbulence and catalysis. When the fixed bed is located in the direction of the heating pipe facing away from the material flow, the heating pipe can be used to turbulently block the impact of the material, and then the fixed bed can be used to react with the catalyst after it is relieved. On the one hand, the material can be slowed down first, making it easier to form a reaction at the catalyst position, and the reaction temperature can be more suitable. However, in the above technical solution, the fixed bed is located in the direction of the heating pipe facing or facing away from the material flow. During the stirring process, the agitator cannot ensure that all liquids can contact the catalyst filled in the fixed bed, so it is difficult to ensure the effect of the reaction. In addition, when the catalyst needs to be replaced, the fixed bed needs to be taken out of the reactor. This process requires cumbersome reactor disassembly and assembly procedures, which is inefficient. Summary of the Invention

DETAILED DESCRIPTION

[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0029] refer to Figure 1 and Figure 2A glass-lined tubular continuous flow reaction device includes a kettle body 10, a stirring member coaxially arranged in the kettle body 10, and a supporting frame 30 coaxially arranged in the kettle body 10. A jacket 20 is provided on the outside of the kettle body 10. An external temperature control device can transport liquid into the jacket 20 through a pipeline to adjust the reaction temperature in the kettle body 10. A temperature detector 14 for monitoring the reaction temperature in the kettle body 10 is installed in the kettle body 10. The kettle body 10 has an infusion port 101 at the bottom and a discharge port 102 at the top. The liquid to be reacted is input into the kettle body 10 through the infusion port 101 and flows upward in the kettle body 10. During this process, the liquid in the kettle body 10 can react and accelerate the reaction rate with the assistance of the catalyst. Subsequently, the reacted liquid can be discharged from the kettle body 10 through the discharge port 102.

[0030] refer to Figure 2 The stirring member includes a stirring shaft 15 coaxially rotating in the kettle body 10 and a blade 151 provided on the stirring shaft 15. In this embodiment, two blades 151 are provided along the axial direction of the stirring shaft 15 and are in an inclined state. A driving source 1 for driving the stirring shaft 15 to rotate is installed on the top of the kettle body 10. The driving source 1 can be a motor 16. The driving source 1 controls the direction of rotation of the stirring shaft 15 to be clockwise (looking from top to bottom along the axial direction of the stirring shaft 15). When the stirring shaft 15 rotates, the reaction rate of the liquid can be accelerated through the blade 151. At the same time, the inclined blade 151 can cause the liquid in the kettle body 10 to disturb upward, so as to assist the liquid in the kettle body 10 to flow upward continuously.

[0031] refer to Figure 2-Figure 9 A plurality of inclined accommodating cavities 31 are evenly arranged along the circumference of the supporting frame 30. In this embodiment, there are six accommodating cavities 31, which are used to hold catalyst particles. A feeding pipe 11 for feeding into the accommodating cavity 31 is provided above the supporting frame 30, and the upper end of the feeding pipe 11 extends upward from the kettle body 10 and is fixedly connected to the kettle body 10. The feeding pipe 11 is connected to an external catalyst feeding device through a pipeline, and the lower end face of the feeding pipe 11 is fitted with the upper end face of the supporting frame 30. A discharge piece 12 is provided below the supporting frame 30, and the discharge piece 12 is fixedly connected to the kettle body 10. The supporting frame 30 is coaxially rotatably connected to the discharge piece 12. A discharge pipe 121 is provided at the bottom of the discharge piece 12, and the lower end of the discharge pipe 121 extends downward from the kettle body 10 and is connected to an external waste catalyst receiving device.

[0032] The supporting frame 30 rotates coaxially with the stirring shaft 15, and the stirring shaft 15 drives the supporting frame 30 to rotate through a transmission assembly. The transmission assembly includes a gear 1 41 rotatably arranged on the discharge member 12, a gear 2 42 coaxially fixed on the stirring shaft 15, and a gear ring 43 coaxially fixed on the bottom of the supporting frame 30. Gear 1 41 is engaged with gear 2 42 and the gear ring 43 at the same time, so that when the stirring shaft 15 rotates clockwise, the supporting frame 30 can rotate counterclockwise, and the rotation speed of the supporting frame 30 is less than that of the stirring shaft 15.

[0033] The accommodating chamber 31 is provided with a through hole 311 connecting the upper and lower sides of the carrying frame 30, so that the liquid in the kettle body 10 can pass through the carrying frame 30 from bottom to top and contact the catalyst in the accommodating chamber 31. A stirring member 2 is provided for rotating in the accommodating chamber 31, and a driving member for driving the stirring member 2 to rotate is provided on the inner wall of the kettle body 10. The stirring member 2 includes a rotating shaft 32 rotatably connected to the carrying frame 30, two blades 2 321 axially spaced along the rotating shaft 32, and a gear 322 provided at the end of the rotating shaft 32. The accommodating chamber 31 is cylindrical and the rotating shaft 32 is coaxially arranged with the accommodating chamber 31. The deflection directions of the two blades 2 321 are opposite, and the driving member is along the kettle The body 10 has multiple racks 13 fixedly arranged at circumferential intervals and cooperating with gear three 322. Therefore, during the counterclockwise rotation of the supporting frame 30, when gear three 322 engages with the rack 13, gear three 322 can rotate and drive blade two 321 to rotate, so that the two blades two 321 can stir the catalyst particles in the accommodating cavity 31 to clean the deposits generated on the catalyst surface due to long-term use. Since the deflection directions of the two blades two 321 are opposite, the two blades two 321 can push the catalyst particles in the accommodating cavity 31 back and forth to accelerate the shedding of deposits on the catalyst surface, thereby maintaining the stability of the catalytic efficiency.

[0034] The end of the accommodating chamber 31 away from the stirring shaft 15 is higher than the end of the accommodating chamber 31 close to the stirring shaft 15. The top of the accommodating chamber 31 is provided with an inlet 312 and the bottom is provided with an outlet 313. The inlet 312 is located at the top of the end of the accommodating chamber 31 away from the stirring shaft 15, and the outlet 313 is located at the bottom of the end of the accommodating chamber 31 close to the stirring shaft 15. A position sensor is provided at the bottom of the feeding tube 11 to cooperate with the inlet 312. As the supporting frame 30 rotates, the position sensor is used to detect when the inlet 312 moves to the bottom of the feeding tube 11 and is completely aligned, thereby facilitating the addition of catalyst to the inlet 312 through the feeding tube 11. The top of the supporting frame 30 slides along its radial direction and is provided with a position sensor to cooperate with the accommodating chamber 312. 1, an upper sealing plate 33 corresponding to the inlet 312 of the accommodating chamber 31 is provided at the bottom along its radial sliding direction with a lower sealing plate 34 corresponding to the outlet 313 of the accommodating chamber 31, the upper sealing plate 33 is connected to the bearing frame 30 through an elastic member 1 331, and the lower sealing plate 34 is connected to the bearing frame 30 through an elastic member 2 341. The elastic member 1 331 and the elastic member 2 341 are respectively springs. A guide is provided for coaxial sliding in the kettle body 10. One end of the upper sealing plate 33 and the lower sealing plate 34 close to the stirring shaft 15 is respectively stopped with the guide member. A driving source 2 for driving the guide member to move is installed on the top of the kettle body 10. The driving source 2 adopts an electric push rod 17. In other embodiments, the driving source 2 may also adopt a cylinder or a hydraulic cylinder.

[0035] The guide member includes a sleeve 50 that is coaxially slidably matched with the stirring shaft 15. The sleeve 50 is sleeved on the outer periphery of the stirring shaft 15. The upper end of the sleeve 50 extends upwardly out of the kettle body 10 and is connected to the telescopic end of the electric push rod 17. An upper guide plate 51 and a lower guide plate 52 are coaxially fixed on the sleeve 50 from top to bottom. The outer periphery of the upper guide plate 51 has an upper guide surface 1 511 and an upper guide surface 2 512. The upper guide surface 1 511 is located above the upper guide surface 2 512. The upper guide surface 2 512 is in an inverted cone shape. When the upper sealing plate 33 stops against the upper guide surface 1 511, the upper sealing plate 33 blocks the inlet 312. The elastic member 1 331 is in a compressed state. When the upper sealing plate 33 stops against the upper guide surface 2 512, the elastic member 1 331 assists the upper sealing plate 33 to open the inlet 312; the outer periphery of the lower guide plate 52 has a lower guide surface 1 521 and the lower end of the lower guide plate 52 is provided with a guide groove 5 22. The guide groove 522 is provided with an inclined lower guide surface 2 523. When the lower sealing plate 34 abuts against the lower guide surface 1 521, the lower sealing plate 34 blocks the outlet 313, and the elastic member 2 341 is in a compressed state. When the lower sealing plate 34 abuts against the bottom of the guide groove 522, the elastic member 2 341 assists the lower sealing plate 34 to open the outlet 313. The lower guide surface 2 523 is inclined so that when the supporting frame 30 rotates counterclockwise, the lower sealing plate 34 enters the guide groove 522 from the state of abutting against the lower guide surface 1 521 and abuts against the bottom of the guide groove 522. The lower sealing plate 34 can smoothly change from the state of abutting against the bottom of the guide groove 522 to the state of abutting against the lower guide surface 1 521 through the lower guide surface 2 523. It should be noted that the bottom of the guide groove 522 is the bottom position of the guide groove 522 close to the axis of the stirring shaft 15 in the horizontal direction.

[0036] It should be noted that the angle between two adjacent lower sealing plates 34 is greater than the opening size of the guide groove 522. When the guide member moves upward and one of the inlets 312 completely corresponds to the feeding tube 11, each lower sealing plate 34 stops at the lower guide surface 521, and the guide groove 522 is located between the two adjacent lower sealing plates 34.

[0037] It should be noted that when the guide member moves downward, the upper sealing plate 33 stops against the upper guide surface 511, and the lower sealing plate 34 stops against the lower guide surface 521, and the inlet 312 and the outlet 313 are both in a blocked state; when the guide member moves upward, the upper sealing plate 33 stops against the upper guide surface 511, and as the supporting frame 30 rotates, the lower sealing plates 34 will enter the guide groove 522 one by one.

[0038] The bottom of the supporting frame 30 has a collecting cavity 35, and the discharge piece 12 has a funnel-shaped collecting cavity. The discharge pipe 121 is connected to the funnel bottom of the collecting cavity. The bottom of the collecting cavity 35 has a drop hole 351 for allowing the material to fall into the collecting cavity. When the lower sealing plate 34 opens the outlet 313, the catalyst particles in the accommodating cavity 31 can flow into the collecting cavity 35 through the outlet 313, and then flow into the collecting cavity through the drop hole 351, and then be discharged from the kettle body 10 through the discharge pipe 121.

[0039] Specific working principle: Reference Figures 1-9 In the initial state, a certain amount of catalyst particles (close to four-fifths of the volume of the accommodating chamber 31) is placed in each accommodating chamber 31, and the end of each upper sealing plate 33 close to the guide member is abutted against the upper guide surface 511, and the end of each lower sealing plate 34 close to the guide member is abutted against the lower guide surface 521. The inlet 312 and the outlet 313 are both in a blocked state. During the clockwise rotation of the stirring shaft 15, the supporting frame 30 can rotate slowly counterclockwise, and the stirring member 2 can intermittently stir the catalyst in the accommodating chamber 31 to extend the service life of the catalyst and maintain the catalytic efficiency.

[0040] After the kettle body 10 has been working for a period of time, the catalyst in each receiving cavity 31 will sinter or agglomerate between particles, resulting in a decrease in the specific surface area of the catalyst and a decrease in activity. In order to ensure the reaction effect of the solution, the catalyst in each receiving cavity 31 needs to be replaced at this time. When replacing, it is necessary to ensure that the liquid in the kettle body 10 is emptied or the liquid level is below the discharge piece 12.

[0041] Next, when replacing the catalyst, two implementation methods can be adopted. Example 1:

[0042] Step 1: Control the guide member to move upward through the electric push rod 17, the upper sealing plate 33 disengages from the upper guide surface 1 511 and starts to stop with the upper guide surface 2 512, and multiple upper sealing plates 33 are all separated from the blockage of the inlet 312, and then the stirring shaft 15 is controlled to rotate clockwise, and the supporting frame 30 can rotate slowly counterclockwise, and the lower sealing plates 34 corresponding to each accommodating cavity 31 will open the corresponding outlet 313 in turn, so that the catalyst particles in each accommodating cavity 31 can flow into the collecting cavity 35 through the outlet 313, and the rotation of the stirring member 2 can also assist the catalyst particles in the accommodating cavity 31 to flow into the collecting cavity 35 through the outlet 313, and the catalyst particles flowing into the collecting cavity 35 will then flow into the collecting cavity through the drop hole 351, and then be discharged from the kettle body 10 through the discharge pipe 121.

[0043] Step 2: Control the support frame 30 to rotate until the position sensor detects that one of the inlets 312 moves to the bottom of the feeding tube 11 and is completely aligned with it, and then stop the rotation of the support frame 30. At this time, control the catalyst feeding equipment to add a certain amount of catalyst particles through the feeding tube 11 into the accommodating cavity 31 corresponding to the inlet 312.

[0044] Step 3: Control the supporting frame 30 to continue rotating 60°. At this time, the next inlet 312 completely corresponds to the feeding tube 11 . At this time, control the catalyst feeding equipment to add a certain amount of catalyst particles into the accommodating cavity 31 corresponding to the inlet 312 through the feeding tube 11 .

[0045] Step 4: Repeat step 3 until the catalyst is added into the sixth receiving chamber 31 .

[0046] Then, the electric push rod 17 is controlled to move the guide member downward, and the upper sealing plate 33 and the lower sealing plate 34 respectively block the inlet 312 and the outlet 313, and then the liquid to be reacted can be continuously input into the kettle body 10 through the infusion port 101 for reaction.

[0047] Example 2:

[0048] S1: Control the support frame 30 to rotate until the position sensor detects that one of the inlets 312 moves to the bottom of the feeding tube 11 and completely corresponds to the inlet 312 , and then stop the support frame 30 from rotating.

[0049] S2: The guide member is controlled to move upward by the electric push rod 17, and the upper sealing plate 33 is disengaged from the upper guide surface 1 511 and begins to abut against the upper guide surface 2 512. Multiple upper sealing plates 33 are disengaged from the blockage of the inlet 312, and the guide groove 522 is located between two adjacent lower sealing plates 34. At this time, all lower sealing plates 34 are abutted against the lower guide surface 1 521, and all outlets 313 are blocked.

[0050] S3: Control the supporting frame 30 to rotate 60°. During this process, the lower sealing plate 34 corresponding to the next inlet 312 will first enter the guide groove 522 and then smoothly change from the state of abutting against the bottom of the guide groove 522 to the state of abutting against the lower guide surface 1 521 through the lower guide surface 2 523, so that the catalyst particles in the accommodating cavity 31 corresponding to the lower sealing plate 34 can flow into the collecting cavity 35 through the corresponding outlet 313, and then be discharged from the kettle body 10 through the discharge pipe 121. When the supporting frame 30 completes the 60° rotation, the inlet 312 of the accommodating cavity 31 is completely corresponding to the bottom of the feeding pipe 11, and then the catalyst feeding equipment is controlled to add a certain amount of catalyst particles into the accommodating cavity 31 through the feeding pipe 11.

[0051] S4: Repeat S3 until the catalyst is completely added into the accommodation chamber 31 corresponding to the inlet 312 in S1.

[0052] Then, the electric push rod 17 is controlled to move the guide member downward, and the upper sealing plate 33 and the lower sealing plate 34 respectively block the inlet 312 and the outlet 313, and then the liquid to be reacted can be continuously input into the kettle body 10 through the infusion port 101 for reaction.

[0053] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
