[0035] As shown in the background art, in the prior art, a conventional autoclave reactor is generally used for catalytic reaction. The autoclave reactor has an autoclave cavity, into which reactants such as isobutane and butene are supplied, and alkylate oil is formed by contacting the reactants with ionic liquid under alkylation conditions. However, the mass transfer efficiency between the reactants and the ionic liquid in the autoclave reactor is low.

[0036] Based on this, the static mixing reactor provided by the present application is provided with at least one reactor, one end of the reactor is provided with a first feed port for introducing an ionic liquid catalyst, and the other end of the reactor is provided with a discharge port for discharging the product after the reaction. The reactor includes a plurality of reaction chambers connected in sequence, and a baffle structure is correspondingly provided in the reaction chamber. A second feed port is provided on at least one reaction chamber, and the second feed port is located on the side of the baffle structure facing the first feed port. The reactants are added successively through the second feed ports on each reaction chamber, and the mixed materials are transported successively along each reaction chamber, which can make the reaction more complete. The baffle structure includes at least one first baffle assembly, and the first baffle assembly includes a plurality of first baffles, and the first baffles are arranged at intervals along the radial direction of the reaction chamber, and there is a first angle between the first baffle and the radial direction of the reaction chamber, and the inclination direction of each first baffle is consistent, and a first material channel is formed between two adjacent first baffles. The first material channel can redistribute the reaction materials to prevent the reaction materials from being concentrated on the inner wall of the reaction chamber, so that the reaction materials and the ionic liquid catalyst can fully contact and react in the first material channel, thereby improving the mass transfer efficiency.

[0037] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0038] Figure 1 A schematic diagram of the structure of a static mixing reactor provided in an embodiment of the present application; Figure 2 for Figure 1 Structural schematic diagram of the middle baffle structure; Figure 3 for Figure 2 A schematic diagram of the structure from another angle.

[0039] Reference Figures 1 to 3As shown, the static mixing reactor provided in the present application includes at least one reactor, one end of the reactor is provided with a first feed port 100, and the other end of the reactor is provided with a discharge port 200.

[0040] The reactor comprises a plurality of reaction chambers 300 connected in sequence, wherein a baffle structure 400 is correspondingly arranged in the reaction chamber 300, and at least one reaction chamber 300 is provided with a second feed port 500, which is located on the side of the baffle structure 400 facing the first feed port 100.

[0041] The deflection structure 400 includes at least one first deflection component 410, and the first deflection component 410 includes a plurality of first deflection members 411. The first deflection members 411 are arranged at intervals along the radial direction of the reaction chamber 300, and a first angle is formed between the first deflection members 411 and the radial direction of the reaction chamber 300. The inclination directions of the first deflection members 411 are consistent, and a first material channel 412 is formed between two adjacent first deflection members 411.

[0042] At least one reactor, that is, the reactor can be one or more. The number of reactors can be set according to actual needs to adapt to different reaction scales and production requirements. The embodiments of the present application do not impose too many restrictions on this.

[0043] In specific implementation, multiple reactors can be set up, and multiple reactors are arranged in parallel. Then, two adjacent reactors are connected in sequence through pipelines to form a multi-stage static mixing reactor. The materials enter the next reactor connected to it from the upper reactor in sequence, and finally discharge from the last reactor. The reactors are arranged in a compact manner, which can shorten the material transportation time and improve the transportation efficiency. The reactors are connected in sequence to form a continuous transportation channel, which realizes the continuous feeding and continuous discharging of materials, can solve the problem of low production capacity of a single small-capacity reactor, and increase the output of alkylate oil.

[0044] It should be noted that the first feed port 100 is used to introduce the ionic liquid catalyst, and the discharge port 200 is used to discharge the product after the reaction. The first feed port 100 and the discharge port 200 are respectively arranged at the two ends of the reactor. The ionic liquid catalyst flows from one end of the reactor to the other end, so that the ionic liquid passes through the entire internal space of the reactor, making the material mixing more uniform.

[0045] The reactor includes a plurality of reaction chambers 300 connected in sequence, at least one reaction chamber 300 is provided with a second feed port 500, the second feed port 500 is a feed port for reactants, the reactants are added successively through the second feed port 500 on each reaction chamber 300, and the mixed materials are transported in sequence along each reaction chamber 300, which can make the reaction more complete.

[0046] Exemplarily, the second feed port 500 may be a circular hole with a diameter of 120 mm; the second feed port 500 may also be a square hole, or a hole of other shapes. The embodiment of the present application does not impose too many restrictions on the shape of the second feed port 500.

[0047] A deflection structure 400 is correspondingly arranged in the reaction chamber 300, and the deflection structure 400 includes at least one first deflection component 410. The first deflection member 411 is arranged at radial intervals along the reaction chamber 300. Specifically, the opposite sides of the first deflection member 411 are respectively connected to the inner wall of the reaction chamber 300 to fix the first deflection member 411 in the reaction chamber 300.

[0048] The shearing effect of the first deflector 411 can cause the fluid to produce very small droplets and a larger phase interface area, thereby reducing the mass transfer resistance and increasing the mass transfer coefficient, so as to enhance the mixing effect and reaction efficiency of the materials.

[0049] There is a first angle between the first baffle 411 and the radial direction of the reaction chamber 300, which can increase the flow path of the material, and the inclination direction of each first baffle 411 is consistent, and a first material channel 412 is formed between two adjacent first baffles 411. The first material channel 412 can redistribute the reaction material to prevent the reaction material from being concentrated on the inner wall of the reaction chamber 300, so that the reaction material and the ionic liquid catalyst can fully contact and react in the first material channel 412, thereby improving the mass transfer efficiency and ensuring sufficient reaction.

[0050] When the reaction is carried out, the ionic liquid catalyst can be first added from the first feed port 100 of the first-stage reactor, and the reaction raw materials are added one by one through the second feed port 500 on each reaction chamber 300. The mixed materials are transported along each reaction chamber 300 in sequence. After the materials are mixed, the fluid is broken into fine droplets under the action of the first deflector 411, so as to achieve efficient mixing and rapid reaction of the ionic liquid and the reactants. After the reaction is completed, the product is discharged from the discharge port 200 of the last-stage reactor. During the whole process, the reaction materials are added in batches, which promotes mass transfer between materials and improves the reaction efficiency. Moreover, the residence time is uniform and controllable, which is suitable for ionic liquid-catalyzed carbon tetraalkylation reaction.

[0051] In some embodiments, reference Figure 2 As shown, the first angle is 50°-70°.

[0052] The first angle is 50°-70°, and the first angle is Figure 2 The angle α indicated by the arrow in the middle, exemplarily, the first angle can be 50°, 60°, or 70°. The embodiment of the present application does not impose too many restrictions on the angle of the first angle.

[0053] It should be noted that the first angle is 50°-70°, which can generate appropriate turbulence and shear force when the fluid flows through the first deflector 411, thereby enhancing the mixing effect between the ionic liquid and the reactants. Moreover, the first deflector 411 has an angle of 50°-70° with the radial direction of the reaction chamber 300, which can increase the flow path of the material and further enhance the mixing effect on the one hand, and force the material to change the flow path and increase the flow resistance of the fluid on the other hand. This change in path can cause the fluid to rotate and flip more inside the reaction chamber 300, thereby improving the mixing effect.

[0054] Figure 4 for Figure 3 Schematic diagram of the structure of the first deflector.

[0055] In some embodiments, reference Figure 4 As shown, the first deflector 411 is a corrugated sheet.

[0056] It is understandable that the corrugated sheet can, on the one hand, break the fluid into fine droplets to achieve efficient mixing and rapid reaction of the ionic liquid and isobutane; on the other hand, it can effectively increase the flow path of the material and enhance the mixing effect. For example, the thickness of the corrugated sheet can be 2 mm or 3 mm, and the embodiments of the present application do not impose too many restrictions on this.

[0057] In some embodiments, reference Figure 4 As shown, the corrugated sheet includes a plurality of bending segments 1411 , and a second angle is formed between two adjacent bending segments 1411 , and the second angle is 89°-91°.

[0058] There is a second angle between two adjacent bending sections 1411, which can generate turbulence and shear force when the fluid flows through the bending section 1411. Such turbulence and shear force can effectively mix the fluids together, thereby improving the mixing efficiency. The second angle is 89°-91°, that is, Figure 4 The arrow in the middle indicates an angle β. For example, the second angle may be 90°.

[0059] It should be noted that the height of the bending section 1411 (ie Figure 4 The length of H indicated by the middle arrow) can be 20 mm or 30 mm, and the length of the bending section 1411 (i.e. Figure 4 The length of L indicated by the middle arrow can be 20 mm or 30 mm. The embodiment of the present application does not impose too many restrictions on the size of the corrugated sheet.

[0060] In some embodiments, reference Figure 2As shown, the deflection structure 400 also includes at least one second deflection component 420, and the second deflection component 420 includes a plurality of second deflection members 421. The second deflection members 421 are arranged at radial intervals along the reaction chamber 300, and the inclination directions of the second deflection members 421 are consistent. A second material channel 422 is formed between two adjacent second deflection members 421, and the first material channel 412 is connected to the second material channel 422.

[0061] The second baffles 421 are arranged at intervals along the radial direction of the reaction chamber 300, that is, the second baffles 421 are arranged along the radial direction of the reaction chamber 300. Figure 1 As shown by the arrow in the middle, the second deflector 421 is arranged at intervals in the X direction, and the shearing effect can further reduce the mass transfer resistance, increase the mass transfer coefficient, and thus enhance the mixing effect of the materials.

[0062] A second material channel 422 is formed between two adjacent second deflectors 421 . The second material channel 422 can redistribute the reaction materials so that the reaction materials and the ionic liquid catalyst can fully contact and react in the second material channel 422 , further improving the mass transfer efficiency.

[0063] The connecting design between the first material channel 412 and the second material channel 422 can ensure that the fluid can smoothly enter the second deflection component 420 for further mixing and reaction after passing through the first deflection component 410.

[0064] In some embodiments, reference Figure 2 As shown, the first deflector assembly 410 and the second deflector assembly 420 are arranged in sequence and spaced apart, and a third angle is formed between the second deflector 421 and the first deflector 411 .

[0065] The first baffle assembly 410 and the second baffle assembly 420 are arranged in sequence. That is, the first baffle assembly 410 and the second baffle assembly 420 are arranged along Figure 1 The Y direction indicated by the middle arrow is arranged sequentially, so that the material can flow through the first deflector assembly 410 and the second deflector assembly 420 multiple times, further enhancing the mixing effect.

[0066] There is a third angle between the second deflector 421 and the first deflector 411, which can generate a more complex flow path. This complex flow helps to improve the mixing efficiency. The third angle is Figure 2 The arrow in the middle indicates an angle θ. Exemplarily, the third angle may be 100°, 120°, or other angles. The embodiment of the present application does not impose too many restrictions on the angle of the third angle.

[0067] In some embodiments, reference Figure 2 As shown, the first deflector 411 and the second deflector 421 are inclined in opposite directions.

[0068] It should be noted that the first deflector 411 and the second deflector 421 with opposite inclination directions can generate alternating flow paths and turbulence when the fluid flows through the deflection structure 400. Such alternating flow paths can effectively break the laminar flow state of the fluid and enhance the mixing effect. Moreover, the first deflector 411 and the second deflector 421 with opposite inclination directions can generate shear forces and turbulence in different directions during the flow of the fluid, which further helps to break up the droplets and promote mass transfer between materials.

[0069] In some embodiments, reference Figure 1 As shown, the reaction chamber 300 is a circular tube.

[0070] It can be understood that the reaction chamber 300 is a round tube, which can reduce dead angles, make the material flow in the reaction chamber 300 more uniform, and further improve the mixing effect.

[0071] In a specific implementation, the height of the reaction chamber 300 (ie, the length of the circular tube) may be 2000-4000 mm, and the ratio of the height to the diameter may be 4-6, so as to ensure sufficient reaction space and mixing effect.

[0072] In some embodiments, reference Figure 1 As shown, two adjacent reaction chambers 300 are connected via a flange.

[0073] It is understandable that the flanges connect two adjacent reaction chambers 300 to facilitate installation, disassembly and maintenance of the static mixing reactor. Specifically, the flanges are equipped with gaskets and fasteners to provide good sealing performance and prevent fluid leakage. Exemplarily, the number of reaction chambers 300 can be three to eight.

[0074] In some embodiments, reference Figure 1 As shown, the number of the reaction kettles is at least two, and the discharge port 200 of one of the two adjacent reaction kettles is connected to the first feed port 100 of the other one.

[0075] The number of reaction kettles is at least two, that is, there can be two reaction kettles or more than two reaction kettles. The embodiment of the present application does not impose too many restrictions on the number of reaction kettles.

[0076] In a specific implementation, there can be two reactors, that is, the static mixing reactor includes a first reactor and a second reactor, and the discharge port 200 of the first reactor is connected to the first feed port 100 of the second reactor through a pipeline to ensure the connectivity of the entire reaction system and the continuous flow of materials. The first reactor and the second reactor can each have five reaction chambers 300, that is, including Figure 1The first reaction chamber 300, the second reaction chamber 300, the third reaction chamber 300, the fourth reaction chamber 300 and the fifth reaction chamber 300 are sequentially arranged in the Y direction as indicated by the middle arrow, the first feed port 100 is arranged on the first reaction chamber 300, and the discharge port 200 is arranged on the fifth reaction chamber 300. The second feed port 500 can be arranged on all five reaction chambers 300 of the first reactor, the second feed port 500 is arranged on the first reaction chamber 300, the second reaction chamber 300 and the third reaction chamber 300 of the second reactor, and the second feed port 500 is not arranged on the fourth reaction chamber 300 and the fifth reaction chamber 300 of the second reactor, that is, no new reactants enter the fourth reaction chamber 300 and the fifth reaction chamber 300, so as to ensure the complete reaction of the materials and the efficient separation of the products in the final reaction stage.

[0077] Those skilled in the art can understand that the static mixing reactor provided in the present application is provided with at least one reactor, one end of which is provided with a first feed port 100 for introducing an ionic liquid catalyst, and the other end of the reactor is provided with a discharge port 200 for discharging the product after the reaction.

A second feed port 500 is provided on at least one reaction chamber 300, and the second feed port 500 is located on the side of the baffle structure 400 facing the first feed port 100. The reactants are added successively through the second feed port 500 on each reaction chamber 300, and the mixed materials are sequentially transported along each reaction chamber 300, so that the reaction can be more complete.

[0078] The baffle structure 400 includes at least one first baffle assembly 410, and the first baffle assembly 410 includes a plurality of first baffles 411, the first baffles 411 are arranged at intervals along the radial direction of the reaction chamber 300, and there is a first angle between the first baffles 411 and the radial direction of the reaction chamber 300, the inclination direction of each first baffle 411 is consistent, and a first material channel 412 is formed between two adjacent first baffles 411. The first material channel 412 can redistribute the reaction material to prevent the reaction material from being concentrated on the inner wall of the reaction chamber 300, so that the reaction material and the ionic liquid catalyst can fully contact and react in the first material channel 412, thereby improving the mass transfer efficiency.
