Description

Technical Field

[0001] The invention relates to the technical field of reactors, and in particular to a vertical etherification reactor. Background Art

[0002] Vertical etherification reactor is a chemical equipment used for etherification reaction. Its design feature is that the reactor is placed upright. Fluidized catalyst bed is preferred in certain etherification reactions. The catalyst particles in the fluidized bed are in a constant state of motion, which helps to improve the contact efficiency between the reactants and the catalyst, thereby accelerating the reaction rate.

[0003] The Chinese patent document with the authorization announcement number CN118267958B discloses a catalytic reactor for dichloroethyl ether synthesis, which uses a stirring rod and a stirring clamping plate to achieve a basic stirring and mixing effect, and uses the mutual attraction of the electromagnetic plate to isolate multiple spaces of the pocket for storing the catalyst, ensuring that the catalyst exists in a uniformly distributed isolated storage state in the kettle body, which can ensure that the catalyst in the pocket is in full contact with the mixed material in the kettle body and enhance the catalytic reaction effect, and also facilitate the subsequent centralized and efficient recovery of the catalyst. In addition, during the stirring process, the isolated and stored catalyst part is knocked and dispersed by the cooperation of the inner moving rod, the missing gear, the missing gear ring and the flat spiral spring, so as to further enhance the full mixing of the catalyst and the mixed material.

[0004] The above technical solution isolates the bag into multiple spaces and disperses the catalyst by knocking. The catalyst will gather at the bottom of the bag. If the bag is fixed, it is difficult for the catalyst in the bag to fully contact with the material. If the bag rotates, the catalyst in the bag will move toward the edge of the bag under the action of centrifugal force, and it is difficult for the catalyst to fully contact with the material. After a period of reaction, the catalyst solidifies. Although the bag is knocked by knocking to avoid catalyst agglomeration in the above technical solution, the knocking effect has a low effect on the breakage of the catalyst. In summary, the reaction rate of the etherification reaction in the prior art decreases after a period of reaction. Summary of the invention

[0027] 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.

[0028] like Figure 1-Figure 6 As shown, a vertical etherification reactor comprises a reactor body 1, a stirring shaft 2, stirring blades 3 spirally arranged on the periphery of the stirring shaft 2, and a driving member 4 for rotating the stirring shaft 2. The interior of each stirring blade 3 is hollow for storing catalysts. Each stirring blade 3 can rotate and swing up and down with the radial direction of the stirring shaft 2 as the rotation axis. When the stirring blade 3 rotates and swings up and down, the catalyst in the stirring blade 3 can be moved.

[0029] The driving member 4 is a driving motor installed on the top of the reactor body 1. The stirring shaft 2 is connected to the output end of the driving motor. The driving motor rotates to drive the stirring shaft 2 to rotate with its own axis as the rotation axis. The stirring blades 3 are spirally arranged on the periphery of the stirring shaft 2. When the etherification reaction is carried out, the stirring blades 3 can stir the reaction liquids of the upper and lower layers and fully contact with the catalyst in the stirring blades 3, thereby improving the reaction efficiency. When the stirring blades 3 rotate, the reaction liquids of the upper and lower layers are turned over to mix the reaction liquids evenly. At the same time, the catalyst can be rolled in the stirring blades 3 to slow down the agglomeration of the catalyst.

[0030] The outer periphery of the stirring shaft 2 is arranged with a plurality of mounting shafts 21 extending in its radial direction, the stirring blade 3 is hinged at the end of the mounting shaft 21, the stirring shaft 2 is hollow, and a driving device 6 is installed in the stirring shaft 2. In a specific embodiment of the present invention, the driving device 6 includes an electric telescopic rod 61, a rack 62 fixedly arranged at the movable end of the electric telescopic rod 61, and a gear 63 fixedly arranged on the mounting shaft 21, and the rack 62 and the gear 63 are meshed with each other; when the electric telescopic rod 61 is raised or lowered, the rack 62 is driven to be raised or lowered, thereby rotating the gear 63, and the rotation of the gear 63 causes the mounting shaft 21 to rotate, and the rotation of the mounting shaft 21 drives the stirring blade 3 to rotate, and the rotation of the stirring blade 3 causes the catalyst inside to roll, thereby slowing down the compaction of the granular catalyst.

[0031] In other embodiments of the present invention, the driving device 6 includes an electric telescopic rod 61, a push block 65 fixedly arranged at the movable end of the electric telescopic rod 61, and a stop block 66 fixedly arranged on the mounting shaft 21; when the electric telescopic rod 61 descends, the push block 65 contacts the stop block 66 and pushes the stop block 66 to rotate, thereby rotating the mounting shaft 21, and the rotation of the mounting shaft 21 causes the stirring blade 3 to rotate.

[0032] After the etherification reaction has been going on for a period of time, the catalyst in the stirring blade 3 may become compacted. At the same time, when the stirring shaft 2 drives the stirring blade 3 to rotate, under the action of centrifugal force, the catalyst in the stirring blade 3 will gather toward the side away from the stirring shaft 2, thereby affecting the reaction efficiency.

[0033] A reset member 5 is hinged between the stirring blade 3 and the mounting shaft 21. The interior of the mounting shaft 21 is hollow. The movable end of the electric telescopic rod 61 is connected to a connecting rope 34. The connecting rope 34 passes through the hollow part of the mounting shaft 21 into the stirring blade 3 and is connected to the stirring blade 3. It should be noted that the reset member 5 and the connecting rope 34 are arranged alternately up and down, a reset spring 35 is connected between the connecting rope 34 and the inner wall of the stirring blade 3, and a first torsion spring 64 is also installed between the mounting shaft 21 and the inner wall of the stirring shaft 2.

[0034] After the etherification reaction has been carried out for a period of time, the electric telescopic rod 61 descends to a certain height until the rack 62 is out of contact with the gear 63. At this time, when no torsion force is applied to the first torsion spring 64 and the reset member 5, the stirring blade 3 is in a horizontal state. When the electric telescopic rod 61 continues to descend, the connecting rope 34 is in a taut state and finally pulls the stirring blade 3 to swing downward. At this time, the reset member 5 accumulates force. When the electric telescopic rod 61 rises, the stirring blade 3 is restored to a horizontal state under the action of the reset member 5. The electric telescopic rod 61 is continuously raised and lowered to make the stirring blade 3 swing up and down. During the up and down swinging of the stirring blade 3, the upper and lower layers of reaction liquid are turned over. When the upper and lower layers of reaction liquid impact the catalyst in the stirring blade 3, the catalyst can be overcome to a certain extent. The situation of gathering toward one side of the stirring blade 3.

[0035] In a specific embodiment of the present invention, the reset member 5 includes an articulated shaft 51 and a second torsion spring 52. The articulated shaft 51 is used to connect the stirring blade 3 and the mounting shaft 21. The second torsion spring 52 is connected between the mounting shaft 21 and the articulated shaft 51. When the first torsion spring 64 is not applied with torsional force, the reset member 5 is above the connecting rope 34, and the electric telescopic rod 61 descends to move the connecting rope 34 toward the stirring shaft 2, and the stirring blade 3 swings downward. At this time, the reset spring 35 and the second torsion spring 52 both store force, and the stirring blade 3 switches between a horizontal state and a tilted downward state, thereby exchanging the upper and lower layers of reaction liquid.

[0036] In other preferred embodiments of the present invention, when no torsion force is applied to the first torsion spring 64 and the second torsion spring 52, the stirring blade 3 is in an inclined upward state. At this time, when the stirring shaft 2 rotates, the catalyst in the stirring blade 3 gathers toward the stirring shaft 2 under the action of gravity. When the stirring shaft 2 rotates, under the action of centrifugal force, the catalyst moves toward the edge of the stirring blade 3. The gravity of the catalyst and the applied centrifugal force offset each other so that the catalyst can be evenly distributed in the stirring blade 3. At this time, when the connecting rope 34 applies tension to the stirring blade 3, the stirring blade 3 is converted between the inclined upward state and the horizontal state.

[0037] When the first torsion spring 64 is twisted, the connecting rope 34 is in a relaxed state, that is, the first torsion spring 64 and the reset member 5 are not twisted at the same time; when the connecting rope 34 is in a taut state and applies force to the reset member 5, the stirring blade 3 only swings up and down without rotating; that is, the swinging and self-rotation of the stirring blade 3 are not performed at the same time; the stirring blade 3 only swings up and down to exchange the reaction liquids in the upper and lower layers, while preventing the connecting rope 34 from twisting in a taut state and shortening the service life of the connecting rope 34.

[0038] In a specific embodiment of the present invention, a plurality of partition plates 31 are fixedly arranged inside the stirring blade 3 to divide the interior of the stirring blade 3 into a plurality of storage bins 32, and a partition assembly 37 sliding along the radial direction of the stirring shaft 2 is arranged in each storage bin 32, and the partition assembly 37 includes a sliding sleeve 371 slidingly arranged on the upper and lower inner walls of the stirring blade 3, a partition tooth plate 372 is installed between the two sliding sleeves 371, and a compression spring 373 is arranged between the partition tooth plate 372 and the sliding sleeve 371, and each partition plate 31 is provided with an opening, and a connecting rope 34 is connected to each partition tooth plate 372 and passes through the opening; when the connecting rope When 34 moves toward the stirring shaft 2, the dividing tooth plate 372 moves toward the stirring shaft 2 and finally contacts with the partition plate 31. When the dividing tooth plate 372 moves, it pushes the catalyst toward the axis center of the stirring shaft 2. At the same time, the dividing tooth plate 372 crushes the agglomerated catalyst when moving toward the partition plate 31. When the dividing tooth plate 372 contacts with the partition plate 31, continue to pull the connecting rope 34 to deflect the stirring blade 3 upward or downward. When the electric telescopic rod 61 rises, under the action of the reset spring 35, the connecting rope 34 moves toward the side away from the stirring shaft 2 and the dividing tooth plate 372 moves toward the edge of the stirring blade 3.

[0039] Specifically, both sides of the stirring blade 3 are provided with slide grooves, and a slider slidably arranged in the slide groove is fixedly provided on the sliding sleeve 371; when the connecting rope 34 pulls the partition component 37 to move, the slider moves along the slide groove to provide a guide for the movement of the partition component 37.

[0040] The stirring blade 3 is fan-shaped, and the partition plate 31 divides the stirring blade 3 into a plurality of trapezoidal spaces. When the partition plate 31 moves toward the stirring shaft 2, the gap between the partition plate 31 and the partition tooth plate 372 gradually decreases, and the agglomerated catalyst is pushed toward the stirring shaft 2 and finally crushed under the pressure of the partition tooth plate 372.

[0041] A cover plate 33 is provided on the upper / lower side of the stirring blade 3, and through holes 36 are evenly distributed on the cover plate 33. The cover plate 33 is detachably arranged on the stirring blade 3 by fasteners such as screws and bolts; when the catalyst loses its activity and needs to be replaced or cleaned, the cover plate 33 is removed and the catalyst is replaced. When the reaction is carried out, the catalyst contacts the reaction liquid through the through holes 36.

[0042] Working principle: When the etherification reaction is carried out, the installation shaft 21 is first rotated by the driving device 6 and the stirring blade 3 is driven to be in an inclined or vertical state, so that the catalyst in the stirring blade 3 can be fully in contact with the reaction liquid during the reaction; after a period of reaction, there may be a difference in the concentration of the reaction liquid in the upper and lower layers, and the catalyst may be agglomerated. At this time, the active end of the driving device 6 descends and the stirring blade 3 is in a horizontal state under the action of the first torsion spring 64. The stirring blade 3 is hinged to the installation shaft 21 by the reset member 5, and the reset member 5 is connected to the connecting rope 34. The lower offset setting is used. When the connecting rope 34 applies tension to the stirring blade 3 through the driving device 6, the stirring blade 3 is deflected. When the stirring blade 3 loses the tension of the connecting rope 34, it returns to a horizontal state under the action of the reset member 5. The connecting rope 34 continuously applies tension to the stirring blade 3, so that the stirring blade 3 swings up and down, thereby exchanging the upper and lower layers of reaction liquid. When the connecting rope 34 pulls the stirring blade 3 to swing, the connecting rope 34 pulls the partition tooth plate 372 to move toward the stirring shaft 2, and the catalyst agglomerated in the stirring blade 3 is crushed by the partition tooth plate 372.

[0043] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
