Technical Field

Background

Continuous processes are completely realized in the large chemical field, but in the aspects of fine chemical engineering and medicine, due to the factors of too many types, small total output, insufficiently deep process research and the like, the traditional kettle type intermittent process is mostly adopted.

The present invention provides a reaction apparatus 100.

Referring to fig. 1 to 6, a reaction apparatus 100 in an embodiment of the present invention 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;

when two of the connection ports 1355 are opened, a plurality of the reaction tubes 10 may be connected in series to perform a continuous flow reaction.

The technical scheme of the invention is that the adopted reaction device 100 comprises a driving mechanism and a reactor, wherein the reaction comprises a plurality of reaction tubes 10, a reaction cavity 111 for accommodating reactants is formed inside each reaction tube 10, the reaction tubes 10 are provided with a feed inlet 113 and a discharge outlet 115 which are communicated with the reaction cavity 111, the reactants can be put into the reaction cavity 111 through the feed inlet 113, and reaction products can be taken out through the discharge outlet 115.

When the two connection ports 1355 are opened, a plurality of reaction tubes 10 may be connected in series through a connection tube (not shown), so that the reaction apparatus 100 may be used as a continuous flow reaction device, thereby increasing the flexibility of the reaction apparatus 100. In addition, the reaction device 100 of the technical scheme of the invention also has the advantage of plug flow of a tubular reactor, and has strong driving force in the reaction tube, less back mixing and no problem of residual raw materials. The reaction device 100 in the technical scheme of the invention can be applied to both batch reaction processes and continuous reaction processes, and the application range of the reaction device 100 is expanded. And, the actuating mechanism can also drive the reactor to vibrate reciprocally, and the reactor vibrates reciprocally and then can drive the reactant in the reaction chamber 111 to move reciprocally in the reaction chamber 111, so as to improve the mixing effect of the reactant, strengthen the mass transfer and heat transfer efficiency of the reactant, and improve the reaction efficiency.

The reaction device 100 in the embodiment of the invention can realize flexible conversion of batch reaction and continuous reaction, and can also combine batch process and/or semi-continuous process in continuous process, thereby greatly improving the flexibility of the reaction device 100 and improving the application range of the reaction device 100. In addition, the reaction device in the embodiment of the invention can realize high-temperature and high-pressure environment, and has the advantages of strong driving force, capability of accelerating the reaction process, great reduction of the residence time of each step of reaction and the like.

It can be understood that the driving mechanism can replace a stirring paddle in a traditional kettle-type reactor to mix the reaction raw materials of the reactants in the reaction chamber 111, so as to enhance the mixing effect of the reactants in the reaction chamber 111. Further, the driving mechanism may be a linear mechanism such as a vibration exciter, an air cylinder, an electric cylinder, etc., and the driving mechanism may be directly connected to the reaction tube 10, or indirectly connected to the reaction tube 10, as long as the driving mechanism can drive the reaction tube 10 and drive the reactant in the reaction tube 10 to reciprocate, and the connection mode between the driving mechanism and the reaction tube 10 is not limited herein. The driving mechanism may drive the reaction tube 10 to vertically vibrate, or may drive the reaction tube 10 to horizontally vibrate. In one embodiment, both ends of the reaction tube 10 in the axial direction are connected to a driving mechanism, so that the driving mechanism can drive the reaction tube 10 to reciprocate in the radial direction of the reaction tube 10.

Referring to fig. 3, in an 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 both ends of the reaction tube 10 in a length direction.

In the technical solution of an embodiment of the present invention, two connection ports 1355 are respectively located at two ends of the reaction tube 10 in the axial direction, so that when a continuous reaction is required, two adjacent reaction tubes 10 can be connected to the connection ports 1355 through a connection tube, so as to realize the series connection of a plurality of reaction tubes 10. It can be understood that, two connectors 1355 are respectively disposed at two ends of the reaction tubes 10 in the axial direction, and when the adjacent connecting tubes are connected in series, the connectors 1355 on the same side of the two adjacent reaction tubes 10 can be connected by U-shaped tubes, so that the connection between the adjacent connecting tubes is facilitated, and the arrangement of the connecting tubes can also be facilitated. Further, two connectors 1355 are respectively disposed at two ends of the reaction tube 10 in the axial direction, when a plurality of reaction tubes 10 are connected in series, the reactant needs to leave from the connector 1355 at the other end and enter the next reaction tube 10 after a long distance in the reaction tube 10, so that the residence time of the reactant in the reaction chamber 111 is longer, the reactant can react in a more sufficient time, the mixing effect of the reactant is further improved, and the reaction efficiency is further improved.

Referring to fig. 6, in an embodiment of the present invention, a dispersion structure 15 is further disposed in the reaction chamber 111, and the dispersion structure 15 extends along an axial direction of the reaction tube 10.

In the technical scheme of an embodiment of the invention, the dispersing structure 15 is arranged in the reaction cavity 111 to replace a stirring shaft in the kettle-type reactor, and because the stirring shaft is not arranged, the problem of shaft sealing of the stirring shaft is not needed, the structure of the reaction device 100 can be well simplified, so that the reaction device 100 has a simple structure and low cost, the applicable temperature and pressure range of the reaction tube 10 is wider, and the application range of the reaction device 100 is widened. The dispersing structure 15 is arranged along the axial direction of the reaction tube 10, and can disperse the reactants at each position of the axial direction of the reaction tube 10, so that the mixing effect is improved.

Further, referring to fig. 6, the dispersing structure 15 may be a first dispersing plate 151, a length direction of the first dispersing plate 151 extends along an axial direction of the reaction tube 10, and a plurality of first through holes 1511 are further provided at intervals on the first dispersing plate 151. The first via 1511 is convenient for the reactant to pass through, and the first via 1511 may be a round hole, or a square hole, a special-shaped hole, or the like. 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 a plurality of first through holes 1511 are further provided at intervals in the first dispersion plate 151.

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 may shear the fluid reactant moving along the radial direction of the reaction tube 10, enhancing the mixing effect of the fluid. When gas is still in the reaction chamber 111 to participate in the reaction, and when the driving mechanism drives the reaction tube 10 to move, the first dispersion plate 151 can also enable the gas and the liquid to generate strong convection, increase the contact area of the gas and the liquid, and improve the gas-liquid mixing effect.

Specifically, for example, when the driving mechanism drives the reaction tube 10 to move upwards, the liquid in the reaction tube 10 can obtain an upward initial velocity, so that the liquid can overcome gravity and the tension of the liquid surface, and move upwards under the action of inertia, the liquid continues to move upwards through the first through hole 1511 after being sheared by the first dispersion plate 151, so as to squeeze the space of the gas, so that the gas can flow towards the bottom of the liquid, so as to form a convection current of the gas and the liquid, the liquid rapidly moves downwards after colliding with the wall of the top of the reaction chamber 111, the liquid continues to move downwards through the first through hole 1511 after being sheared by the first dispersion plate 151, so that the rising gas and the liquid form a convection current again, the liquid obtains an upward initial velocity again after abutting against the wall of the bottom of the reaction chamber 111, and reciprocates, so as to greatly increase the gas-liquid mixing efficiency in the reaction chamber 111, greatly improving the mass and heat transfer efficiency.

Referring to fig. 6, in an embodiment of the present invention, the dispersing structure 15 further includes a plurality of second dispersing plates 153, the plurality of second dispersing plates 153 extend along the axial direction of the reaction tube 10 and are connected to the first dispersing plates 151, and the second dispersing plates 153 are provided with a plurality of second through holes 1531 at intervals.

In the technical solution of an embodiment of the present invention, the second dispersion plates 153 are disposed at intervals along the axial direction of the reaction tube 10, so that the flow velocity of the liquid in the reaction tube 10 can be effectively reduced, the reaction time can be prolonged, and the back-mixing of the fluid in the reaction tube 10 can be reduced by the second dispersion plates 153. Specifically, the second dispersion plate 153 has the same shape as the cross-sectional shape of the reaction tube 10, that is, the second dispersion plate 153 is a circular plate, and the plurality of second dispersion plates 153 and the first dispersion plate 151 are integrated, so that the fixing is facilitated and the difficulty of assembly is reduced.

The second dispersion plate 153 is further provided with a second through hole 1531 for allowing liquid to pass through, and the second through hole 1531 may be a circular hole, a square hole, a stepped hole, or the like. The second dispersion plate 153 may have the second via hole 1531 on the whole plate surface, or may have the second via hole 1531 in a local area.

In an embodiment, only half of the area of the second dispersion plate 153 may be provided with the second via 1531. In addition, the second through holes 1531 of the two adjacent second dispersion plates 153 are disposed in a staggered manner, that is, the second through hole 1531 of one second dispersion plate 153 of the two adjacent second dispersion plates 153 is disposed above the first dispersion plate 151, and the second through hole 1531 of the other second dispersion plate 153 is disposed below the first dispersion plate 151, so that the flow rate of the liquid in the reaction tube 10 can be further reduced, and the reaction time can be prolonged.

Referring to fig. 1 and 2, in an embodiment of the present invention, the reaction tube 10 includes a tube body 11 and two sealing assemblies 13, the two sealing assemblies 13 are detachably connected to two ends of the tube body 11 in an axial direction, the tube body 11 and the two sealing assemblies 13 form the reaction chamber 111, the tube body 11 is provided with the inlet 113 and the outlet 115, the inlet 113 and the outlet 115 are respectively provided at two ends of the tube body 11 in the axial direction, and an end surface of the sealing assembly 13 is provided with the connection port 1355.

In an embodiment of the present invention, the length/diameter ratio of the tube 11 is 2 to 10, so as to ensure the reaction space of the reaction chamber 111. The seal assembly 13 and the tubular body 11 are removably connected to facilitate locating the dispersing structure 15 within the tubular body 11. The sealing assembly 13 and the pipe body 11 can be detachably connected through a thread structure, and can also be detachably connected with the pipe body 11 through a screw structure and the like. Seal assembly 13 includes end cap 131 and seal cap 135. The end cap 131, the sealing cap 135 and the tube 11 are made of metal. Wherein, the inner wall surface of the end cap 131 is provided with a first thread 117, 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 of the end cap 131 and the tube body 11.

In one embodiment, the seal assembly 13 is further provided with a screen plate having an aperture in the range of 0.5mm to 20 mm.

Further, referring to fig. 1 to 4, in an embodiment of the present invention, the reaction apparatus 100 further includes a heat exchanging mechanism 20, and the heat exchanging mechanism 20 is disposed on a surface of the tube 11.

In the technical scheme of the embodiment of the invention, the heat exchange mechanism 20 is arranged, and the heat exchange mechanism 20 is directly sleeved on the outer surface of the tube body 11, so that uniform heat exchange with reactants in the reaction tube 10 can be realized, the reaction device 100 can be suitable for reaction processes at various temperatures, the reactants can smoothly release or absorb heat, and the application range of the reaction device 100 is widened.

Specifically, the heat exchange mechanism 20 may be a heat exchange tube, a heat exchange clip, or another structure. The heat exchange clamp and the outer surface of the pipe body 11 are enclosed to form a heat exchange cavity 21, and the heat exchange cavity 21 is used for accommodating a heat exchange medium. The heat exchange medium may be a heat exchange fluid, such as water, oil, etc. Further, the heat exchange mechanism 20 is further provided with a heat exchange inlet 23 and a heat exchange outlet 25 which are communicated with the heat exchange cavity 21, so that the heat exchange medium can be supplemented or replaced, and a good heat exchange effect can be guaranteed.

In an embodiment, in order to better improve the heat exchange efficiency, the plurality of heat exchange cavities 21 may be connected in series by using a connecting pipe, so that the heat exchange medium in the plurality of heat exchange cavities 21 can flow, thereby improving the heat exchange efficiency. In an embodiment, the heat exchanging mechanism 20 can also use an electric heating method to control the reaction temperature in the reaction chamber 111.

Further, referring to fig. 5, in an embodiment of the present invention, the reaction apparatus 100 further includes a feeding three-way valve 30 and a discharging three-way valve 40, the feeding three-way valve 30 is connected to the feeding port 113, and the discharging three-way valve 40 is connected to the discharging port 115.

In the solution of an embodiment of the present invention, a feeding three-way valve 30 is connected to the feeding port 113 of the reaction tube 10, so as to add the reactant into the reaction chamber 111. Specifically, the three-way feed valve 30 is a tubular three-way valve including an inner sleeve and an outer sleeve, wherein one end of the inner sleeve is insertable into the reaction chamber 111 to facilitate feeding of the material into the reaction chamber 111. It is understood that the solid particles and the liquid reactant may flow into the reaction chamber 111 through the same port of the feed three-way valve 30, and the gaseous reactant may flow into the reaction chamber 111 through the other port of the feed three-way valve 30. Since one end of the inner sleeve can be inserted into the reaction chamber 111 and can directly contact with the reactant in the reaction chamber 111, the temperature sensor 50 can be fixed at the end of the inner sleeve extending into the reaction chamber 111 to measure the temperature in the reaction chamber 111.

Similarly, the discharge port 115 is also connected to a discharge three-way valve 40 to facilitate the extraction of the reactant obtained in the reaction chamber 111 through the three-way valve. It will be appreciated that the three-way outlet valve 40, like the three-way inlet valve 30, is also a tubular three-way valve, and includes an inner sleeve and an outer sleeve. In an embodiment of the present invention, the reactant in the reaction chamber 111 can be sampled through the discharge tee, so as to facilitate real-time understanding of the reaction condition. In one embodiment, a pressure sensor 60 is further disposed on the discharging three-way valve 40 to monitor the pressure in the reaction chamber 111.

When the reaction apparatus 100 of the present invention is used for a batch reaction, the connection ports 1355 at both ends of each reaction tube 10 may be sealed by plugs, and in this case, each reaction tube 10 may be independently provided with a batch reactor. The reaction mass can be sucked in by vacuum or injected by a syringe pump and the reaction chamber 111 is inflated to the experimental pressure. The reaction chambers 111 arranged in parallel can also adopt DOE (design OF experimenter) experimental design method to optimize the material proportion, solvent type, catalyst type, reaction pressure, reaction temperature, reaction time and other factors OF the reaction, and quickly screen out the optimal process conditions.

Further, since each reaction tube 10 is the same, it is also possible to quickly screen out batch optimized process conditions by high-throughput parallel reactions. Meanwhile, the material flow, the residence time, the reaction temperature and pressure and the like under the continuous process condition can be calculated according to the batch reaction condition, so that the batch reaction chambers 111 are connected in series according to the process flow, and the rapid conversion of the batch process and the continuous process is realized.

When the reaction device 100 of the present invention is used to perform a continuous reaction process, the connection pipe is used to connect the connection ports 1355 on the same side of the adjacent reaction tubes 10, so that a plurality of reaction tubes 10 can be connected in series to form a series-connected multi-stage reactor, and reactants can sequentially flow through each reaction chamber 111 under the pressure of fluid and flow out from the last reaction chamber 111. Further, the reaction chamber 111 may be filled with a catalyst, or a catalyst mixed with solid particles is dispersed into the entire reaction chamber 111 under the action of the driving mechanism, thereby realizing efficient mass and heat transfer of gas, liquid and solid, and realizing continuous synthesis. It will be appreciated that the reaction tube 10 may be parallel to the drive mechanism table or may be perpendicular to the drive mechanism. When the reaction tubes 10 are vertically arranged, the reaction device 100 is suitable for an absorption reaction process, gas and liquid are dispersed into tiny bubbles through a sieve plate and enter the reaction cavity 111, the bottom end of the reaction cavity 111 is liquid, the top end of the reaction cavity is gas, and the top end of the reaction cavity is connected with the bottom end of another reaction tube 10 to form a similar multistage absorption tower. And the liquid at the bottom end continuously generates gas-liquid convection with the gas at the top end under the action of the driving mechanism, and is dispersed into liquid films or liquid drops, so that the contact area between the gas and the liquid is increased, and the absorption efficiency is greatly improved. It is understood that, when the continuous reaction process is performed using the reaction apparatus 100 of the present invention, the three-way feed valve 30 and the three-way discharge valve 40 connected to a portion of the reaction tubes 10 are closed.

The reaction apparatus 100 of the present invention can also be used in a reactive extraction coupling process, for example, when the reaction tube 10 is vertically standing, 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 materials is finished, the extracting agent is added and fully mixed under the action of the driving mechanism, flows into the reaction cavity 111 to be separated, and is forcibly mixed with the extracting agent in the next reaction cavity 111 again, and the materials are extracted and separated continuously for multiple times.

The reaction apparatus 100 in the technical solution of the present invention can also be used in a reactive crystallization coupling process, for example, two interfaces of the reaction tube 10 are in the form of sleeves, and inner tubes of the sleeves can be made into a porous array to form a porous array sleeve mixer, so as to realize rapid microscale mixing and rapid nucleation of the reaction. Then continuous flow ripening and macro mixing are carried out in the reaction chamber 111 to produce uniform-particle crystals. When the crystal particles of part of the process reach more than dozens of microns, the sieve plates at the two ends of the tube body 11 can also filter the crystal particles, and the crystals are trapped in the reaction cavity 111 and can be washed for the second time. The reaction chamber 111 can be heated and nitrogen-blown for drying treatment, and the product is finally obtained.
