Description

Technical Field

[0001] The present invention relates to the technical field of reaction devices, and in particular to a reaction device. Background Art

[0002] In the field of large-scale chemical industry, continuous process has been fully realized. However, in the field of fine chemicals and medicine, due to factors such as too many types, small total output, and insufficient in-depth process research, most of them adopt traditional batch process. The batch reaction process has the advantage of a wide range of adaptability, but it has the disadvantages of severe back-mixing and obvious amplification effect. In industry, multiple batches of batches are often used in series to achieve process continuity. This method has the applicability of batches, while reducing the adverse effects of back-mixing and amplification effects. However, the batch series fully mixed flow reactor (CSTR) converts batch reactions into continuous reaction processes, but has the disadvantages of poor gas-liquid-solid multiphase mixed mass transfer effect, severe raw material residue, and insufficient driving force, which limits its scope of use.

[0034] The present invention provides a reaction device 100 .

[0035] Reference Figures 1 to 6 In one embodiment of the present invention, the reaction device 100 includes a driving mechanism (not shown) and a reactor (not shown), wherein the driving mechanism is connected to the reactor to drive the reactor to vibrate;

[0036] The reactor comprises a plurality of reaction tubes 10, wherein a reaction chamber 111 for accommodating reactants is formed inside the reaction tube 10, and the reaction tube 10 is provided with a feed port 113 and a discharge port 115 communicating with the reaction chamber 111, and the reaction tube 10 is also provided with two communicating connection ports 1355;

[0037] When the two connection ports 1355 are closed, the plurality of reaction tubes 10 can perform intermittent reactions respectively;

[0038] When the two connection ports 1355 are opened, a plurality of reaction tubes 10 can be connected in series to perform a continuous flow reaction.

[0039] The technical solution of the present invention adopts a reaction device 100 including a driving mechanism and a reactor, wherein the reaction includes a plurality of reaction tubes 10, and a reaction chamber 111 for accommodating reactants is formed inside the reaction tube 10, and the reaction tube 10 is provided with a feed port 113 and a discharge port 115 connected to the reaction chamber 111, and the reactants can be put into the reaction chamber 111 through the feed port 113, and the reaction products can also be taken out through the discharge port 115. In addition to the feed port 113 and the discharge port 115, two connection ports 1355 connected to the reaction chamber 111 are also provided on the reaction tube 10, and when the connection port 1355 is closed, the reaction chambers 111 in the plurality of reaction tubes 10 are all independently arranged, and at this time, the reaction device 100 can be used as a reaction device for an intermittent reaction process. When the two connection ports 1355 are opened, at this time, the plurality of reaction tubes 10 can be connected in series through a connecting pipe (not shown), so that the reaction device 100 can be used as a continuous flow reaction device, thereby improving the flexibility of the reaction device 100. Moreover, the reaction device 100 of the technical solution of the present invention also has the advantages of the plug flow of the tubular reactor, and the driving force in the reaction tube is strong, the back mixing is small, and there is no problem of residual raw materials. The reaction device 100 in the technical solution of the present invention can be applied to both intermittent reaction processes and continuous reaction processes, which expands the application range of the reaction device 100. Moreover, the driving mechanism can also drive the reactor to vibrate back and forth, and the reciprocating vibration of the reactor can drive the reactants in the reaction chamber 111 to reciprocate in the reaction chamber 111, thereby improving the mixing effect of the reactants, strengthening the mass transfer and heat transfer efficiency of the reactants, and improving the reaction efficiency.

[0040] The reaction device 100 in the embodiment of the present invention can realize the flexible conversion between intermittent reaction and continuous reaction, and can also combine the intermittent process and / or semi-continuous process in the continuous process, which greatly improves the flexibility of the reaction device 100 and improves the application scope of the reaction device 100. In addition, the reaction device in the embodiment of the present invention can also realize a high temperature and high pressure environment, has the advantages of strong driving force, can accelerate the reaction process, and greatly reduce the residence time of each step of the reaction.

[0041] It can be understood that the driving mechanism can replace the stirring paddle in the traditional kettle reactor to mix the reactants in the reaction chamber 111, thereby enhancing the mixing effect of the reactants in the reaction chamber 111. Furthermore, the driving mechanism can be a linear mechanism such as an exciter, a cylinder, an electric cylinder, etc. The driving mechanism can be directly connected to the reaction tube 10, or it can be indirectly connected to the reaction tube 10. As long as the driving mechanism can drive the reaction tube 10 and drive the reactants in the reaction tube 10 to reciprocate, the connection method between the driving mechanism and the reaction tube 10 is not limited here. The driving mechanism can drive the reaction tube 10 to vibrate vertically or horizontally. In one embodiment, both ends of the reaction tube 10 in the axial direction are connected to the driving mechanism, so that the driving mechanism can drive the reaction tube 10 to reciprocate along the radial direction of the reaction tube 10.

[0042] Reference Figure 3 In one embodiment of the present invention, the reaction tube 10 is provided with an axial direction and a radial direction, and the two connection ports 1355 are respectively provided at two ends of the length direction of the reaction tube 10 .

[0043] In the technical solution of one embodiment of the present invention, the two connecting ports 1355 are respectively located at the two ends of the axial direction of the reaction tube 10. In this way, when a continuous reaction is required, the two adjacent reaction tubes 10 can be connected to the connecting port 1355 through a connecting tube to realize the series connection of multiple reaction tubes 10. It can be understood that the two connecting ports 1355 are respectively arranged at the two ends of the axial direction of the reaction tube 10. When the adjacent connecting tubes are connected in series, the connecting ports 1355 on the same side of the two adjacent reaction tubes 10 can be connected with a U-shaped tube. In this way, it is convenient to connect the adjacent connecting tubes and the arrangement of the connecting tubes. Further, the two connecting ports 1355 are respectively arranged at the two ends of the axial direction of the reaction tube 10. When multiple reaction tubes 10 are connected in series, the reactants need to travel a long distance in the reaction tube 10 to leave from the connecting port 1355 at the other end and enter the next reaction tube 10, so that the reactants stay in the reaction chamber 111 for a longer time, so that the reactants have more time to react, so as to further improve the mixing effect of the reactants, which is more conducive to improving the reaction efficiency.

[0044] Reference Figure 6In one embodiment of the present invention, a dispersion structure 15 is further provided in the reaction chamber 111 , and the dispersion structure 15 is extended along the axial direction of the reaction tube 10 .

[0045] In the technical solution of one embodiment of the present invention, by arranging the dispersion structure 15 in the reaction chamber 111 to replace the stirring shaft in the kettle reactor, since there is no stirring shaft, there is no need to seal the stirring shaft, which can greatly simplify the structure of the reaction device 100, making the reaction device 100 simple in structure and low in cost, and the temperature and pressure range applicable to the reaction tube 10 is wider, thereby improving the application range of the reaction device 100. The dispersion structure 15 is arranged along the axial direction of the reaction tube 10, and can disperse the reactants at various positions in the axial direction of the reaction tube 10, thereby improving the mixing effect.

[0046] Further, refer to Figure 6 The dispersion structure 15 may be a first dispersion plate 151, the length direction of the first dispersion plate 151 extends along the axial direction of the reaction tube 10, and the first dispersion plate 151 is also provided with a plurality of first through holes 1511 at intervals. The first through holes 1511 facilitate the passage of reactants, and the first through holes 1511 may be round holes, square holes, special-shaped holes, etc. The first dispersion plate 151 is rectangular, the length direction of the first dispersion plate 151 extends along the axial direction of the reaction tube 10, the width direction of the first dispersion plate 151 extends along the radial direction of the reaction tube 10, and the first dispersion plate 151 is also provided with a plurality of first through holes 1511 at intervals.

[0047] When the driving mechanism drives the reaction tube 10 to reciprocate along the radial direction of the reaction tube 10, the first dispersion plate 151 can shear the fluid reactant moving along the radial direction of the reaction tube 10, thereby enhancing the mixing effect of the fluid. When there is gas participating in the reaction in the reaction chamber 111, when the driving mechanism drives the reaction tube 10 to move, the first dispersion plate 151 can also cause strong convection between the gas and the liquid, thereby increasing the contact area between the gas and the liquid and improving the gas-liquid mixing effect.

[0048] Specifically, for example, when the driving mechanism drives the reaction tube 10 to move upward, the liquid in the reaction tube 10 can obtain an initial upward velocity, so that the liquid can overcome gravity and the tension on the surface of the liquid and move upward under the action of inertia. After the liquid is sheared by the first dispersion plate 151, it continues to move upward through the first through hole 1511, thereby squeezing the space for the gas, so that the gas can flow to the bottom of the liquid to form gas and liquid convection. After colliding with the cavity wall at the top of the reaction chamber 111, the liquid moves downward rapidly. After being sheared by the first dispersion plate 151, the liquid continues to move downward through the first through hole 1511, so that the rising gas and liquid form convection again. After the liquid abuts against the cavity wall at the bottom of the reaction chamber 111, it obtains the initial upward velocity again, and so on and so forth, thereby greatly increasing the gas-liquid mixing efficiency in the reaction chamber 111 and greatly improving the mass transfer and heat transfer efficiency.

[0049] Reference Figure 6 In one embodiment of the present invention, the dispersion structure 15 further includes a plurality of second dispersion plates 153, the plurality of second dispersion plates 153 extend along the axial direction of the reaction tube 10 and are connected to the first dispersion plate 151, and the second dispersion plates 153 are provided with a plurality of second through holes 1531 at intervals.

[0050] In the technical solution of one embodiment of the present invention, by providing a plurality of second dispersion plates 153 spaced apart along the axial direction of the reaction tube 10, the flow velocity of the liquid in the reaction tube 10 can be effectively reduced, the reaction time can be prolonged, and the second dispersion plates 153 can also reduce the back-mixing of the fluid in the reaction tube 10. Specifically, the shape of the second dispersion plates 153 is the same as the cross-sectional shape of the reaction tube 10, that is, the second dispersion plates 153 are circular plates, and the plurality of second dispersion plates 153 are all integrated with the first dispersion plate 151, which is convenient for fixing and reduces the difficulty of assembly.

[0051] The second dispersion plate 153 is also provided with second through holes 1531 for liquid to pass through, and the second through holes 1531 may be round holes, square holes, stepped holes, etc. The second dispersion plate 153 may have second through holes 1531 on the entire plate surface or in a local area.

[0052] In one embodiment, only half of the second dispersion plate 153 may be provided with the second through holes 1531. Furthermore, the second through holes 1531 of two adjacent second dispersion plates 153 are staggered, that is, of the two adjacent second dispersion plates 153, the second through holes 1531 of one of the second dispersion plates 153 is provided above the first dispersion plate 151, and the second through holes 1531 of the other second dispersion plate 153 is provided below the first dispersion plate 151. Such a configuration can further reduce the flow rate of the liquid in the reaction tube 10 and prolong the reaction time.

[0053] Reference Figure 1 and Figure 2 In one embodiment of the present invention, the reaction tube 10 includes a tube body 11 and two sealing components 13, the two sealing components 13 are detachably connected to the two ends of the tube body 11 in the axial direction, the tube body 11 and the two sealing components 13 form the reaction chamber 111, the tube body 11 is provided with the feed port 113 and the discharge port 115, and the feed port 113 and the discharge port 115 are respectively arranged at the two ends of the tube body 11 in the axial direction, and the end surface of the sealing component 13 is provided with the connecting port 1355.

[0054] In one embodiment of the present invention, the aspect ratio of the tube body 11 is 2 to 10, which can ensure the reaction space of the reaction chamber 111. The sealing assembly 13 and the tube body 11 are detachably connected, so that the dispersion structure 15 can be arranged in the tube body 11. The sealing assembly 13 and the tube body 11 can be detachably connected through a threaded structure, or can be detachably connected to the tube body 11 through a structure such as a screw. The sealing assembly 13 includes an end cap 131 and a sealing cover 135. The end cap 131, the sealing cover 135 and the tube body 11 are all made of metal. Among them, the inner wall surface of the end cap 131 is provided with a first thread 117, and the outer side wall of the tube body 11 is provided with a second thread 1313, and the first thread 117 and the second thread 1313 are engaged to realize the detachable connection between the end cap 131 and the tube body 11. The end cap 131 and the tube body 11 are connected by threads, which can ensure the reliability of the connection and facilitate maintenance.

[0055] The end face of the end cap 131 is also provided with a mounting hole 1311, and the sealing cover 135 includes a sealing portion 1351 and a connecting portion 1353 connected to each other. Among them, the sealing portion 1351 is sandwiched between the end cap 131 and the end face of the tube body 11 to seal the opening at the end of the tube body 11, the connecting portion 1353 is arranged through the mounting hole 1311, and the connecting port 1355 passes through the connecting portion 1353 of the sealing cover 135 to achieve communication with the reaction chamber 111. The connecting port 1355 can form a stepped hole, and the side wall surface of the connecting port 1355 can also be formed with a connecting thread to facilitate connection with the connecting pipe. In one embodiment, the sealing assembly 13 is also provided with a sieve plate, and the sieve plate aperture range is 0.5mm to 20mm. In some embodiments, the connecting ports 1355 provided at both ends of the tube body 11 can also be a feed port 113 or a discharge port 115, and gas or liquid can flow in or out through the connecting port 1355, and the sieve plate can prevent solid particles from passing through.

[0056] Further, refer to Figures 1 to 4 In one embodiment of the present invention, the reaction device 100 further includes a heat exchange mechanism 20 , and the heat exchange mechanism 20 is disposed on the surface of the tube body 11 .

[0057] In the technical solution of one embodiment of the present invention, by setting a heat exchange mechanism 20, the heat exchange mechanism 20 is directly sleeved on the outer surface of the tube body 11, which can achieve uniform heat exchange with the reactants in the reaction tube 10, so that the reaction device 100 can be suitable for reaction processes of various temperatures, which is convenient for the reactants to release or absorb heat smoothly, thereby improving the use range of the reaction device 100.

[0058] Specifically, the heat exchange mechanism 20 can be a heat exchange tube, a heat exchange clip, or other structures. The heat exchange clip and the outer surface of the tube body 11 enclose a heat exchange cavity 21, and the heat exchange cavity 21 is used to contain a heat exchange medium. The heat exchange medium can be a heat exchange fluid, such as water, oil, etc. Further, the heat exchange mechanism 20 is also provided with a heat exchange inlet 23 and a heat exchange outlet 25 connected to the heat exchange cavity 21, so as to facilitate the replenishment or replacement of the heat exchange medium to ensure a good heat exchange effect.

[0059] In one embodiment, in order to improve the heat exchange efficiency, a plurality of heat exchange chambers 21 may be connected in series using a connecting pipe so that the heat exchange medium in the plurality of heat exchange chambers 21 can flow, thereby improving the heat exchange efficiency. In one embodiment, the heat exchange mechanism 20 may also control the reaction temperature in the reaction chamber 111 by means of electric heating.

[0060] Further, refer to Figure 5 In one embodiment of the present invention, the reaction device 100 further includes a feed three-way valve 30 and a discharge three-way valve 40 , wherein the feed three-way valve 30 is connected to the feed port 113 , and the discharge three-way valve 40 is connected to the discharge port 115 .

[0061] In the technical solution of one embodiment of the present invention, a feed three-way valve 30 is connected to the feed port 113 of the reaction tube 10 to facilitate adding reactants into the reaction chamber 111. Specifically, the feed three-way valve 30 is a tubular three-way valve, including an inner sleeve and an outer sleeve, wherein one end of the inner sleeve can be inserted into the interior of the reaction chamber 111 to facilitate adding materials into the reaction chamber 111. It can be understood that solid particles and liquid reactants can flow into the reaction chamber 111 through the same interface of the feed three-way valve 30, and gaseous reactants can flow into the reaction chamber 111 through another interface of the feed three-way valve 30. Since one end of the inner sleeve can be inserted into the interior of the reaction chamber 111, it can directly contact the reactants in the reaction chamber 111, and therefore, a temperature sensor 50 can also be fixed at the end of the inner sleeve extending into the reaction chamber 111 to facilitate measuring the temperature in the reaction chamber 111.

[0062] Similarly, the discharge port 115 is also connected to a discharge three-way valve 40 to facilitate the removal of the reactants obtained in the reaction chamber 111 through the three-way valve. It can be understood that the discharge three-way valve 40 is also a tubular three-way valve like the feed three-way valve 30, and also includes an inner sleeve and an outer sleeve. In one embodiment of the present invention, the reactants in the reaction chamber 111 can be sampled through the discharge three-way valve to facilitate real-time understanding of the reaction situation. In one embodiment, a pressure sensor 60 is also provided at the discharge three-way valve 40 to monitor the pressure in the reaction chamber 111.

[0063] When the reaction device 100 of the present invention is used for intermittent reaction, the connection ports 1355 at both ends of each reaction tube 10 can be blocked with a plug, and at this time, each reaction tube 10 can become an independently arranged intermittent reactor. The reaction material can be sucked in by vacuum or injected by a syringe pump, and inflated to the experimental pressure in the reaction chamber 111. Multiple parallel reaction chambers 111 can also use the DOE (DESIGN OF EXPERIMENT) experimental design method to optimize the material ratio, solvent type, catalyst type, reaction pressure, reaction temperature, reaction time and other factors of the reaction, and quickly screen out the optimal process conditions.

[0064] Furthermore, since each reaction tube 10 is the same, the intermittent optimal process conditions can be quickly screened out through high-throughput parallel reaction. At the same time, the material flow rate, residence time, set reaction temperature, pressure, etc. under the continuous process conditions can be calculated according to the intermittent reaction conditions, so as to facilitate the connection of multiple intermittent reaction chambers 111 in series according to the process flow, and realize the rapid conversion between the intermittent process and the continuous process.

[0065] When the reaction device 100 of the present invention is used for a continuous reaction process, a connecting pipe is used to connect the same side connection port 1355 of the adjacent reaction tubes 10, so that multiple reaction tubes 10 can be connected in series to form a multi-stage reactor in series, and the reactants can flow through each reaction chamber 111 in sequence under the pressure of the fluid, and flow out from the last reaction chamber 111. Further, the reaction chamber 111 can be filled with a catalyst, or a catalyst is mixed in the solid particles, and dispersed into the entire reaction chamber 111 under the action of the driving mechanism, thereby realizing efficient mass transfer and heat transfer of gas, liquid and solid, and realizing continuous synthesis. It can be understood that the reaction tube 10 can be parallel to the driving mechanism table or perpendicular to the driving mechanism. When the reaction tube 10 is arranged vertically, the reaction device 100 is suitable for the absorption reaction process, and the gas and liquid are dispersed into tiny bubbles through the sieve plate and enter the reaction chamber 111. The bottom end of the reaction chamber 111 is liquid, and the top end is gas. The top end is connected to the bottom end of another reaction tube 10, forming a multi-stage absorption tower. Under the action of the driving mechanism, the liquid at the bottom continuously forms gas-liquid convection with the gas at the top, and is dispersed into a liquid film or liquid droplets, thereby increasing the contact area between the gas and the liquid, and greatly improving the absorption efficiency. It can be understood that when the reaction device 100 of the present invention is used to perform a continuous reaction process, the feed three-way valve 30 and the discharge three-way valve 40 connected to some reaction tubes 10 are both closed.

[0066] The reaction device 100 in the technical solution of the present invention can also be used in a reaction-extraction coupling process. For example, when the reaction tube 10 is placed vertically and statically, it can be used as a phase separator, and the heavy phase and the light phase flow out from the bottom and the top of the reaction tube 10, respectively. After the continuous reaction of the material is completed, the extractant is added and fully mixed under the action of the driving mechanism, flows into the reaction chamber 111 for phase separation, and then is forcibly mixed with the extractant again in the next reaction chamber 111, and the extraction and separation are continued multiple times.

[0067] The reaction device 100 in the technical solution of the present invention can also be used for the reaction crystallization coupling process. For example, the two interfaces of the reaction tube 10 are sleeves, and the inner tube of the sleeve can be made into a porous array to become a porous array sleeve mixer, which can achieve rapid microscale mixing and rapid reaction nucleation. Then, continuous flow maturation and macroscopic mixing are carried out in the reaction chamber 111 to produce crystals with uniform particles. When the crystal particles of some processes reach more than tens of microns, the sieve plates at both ends of the tube body 11 can also filter the crystal particles, and the crystals trapped in the reaction chamber 111 can be washed twice. The reaction chamber 111 body can be heated and blown with nitrogen for drying treatment to finally obtain the product.
