Continuous flow reaction module, reaction device and filling block

Technical Field

The utility model relates to a continuous flow reaction unit field, what it specifically related to is one kind can promote the fluid in the continuous flow in-process reaction module of mixed effect to and install this continuous flow reaction module's device and establish the important piece part of filling up in this continuous flow reaction module.

Background

Tubular reactors, kettle reactors and the like are fluid reaction equipment commonly used in the chemical and pharmaceutical fields at present.

Wherein, the tank reactor is generally provided with a stirring device in the reaction tank for mixing liquid phase reactants, and has the problems of low purity of the compositions, low reaction conversion rate and serious energy consumption and pollution. Because of the high purity requirements of products in the chemical and pharmaceutical fields, the continuous flow tubular reactor is relatively a type of reaction equipment which uses more.

Given that the chemical reactant concentration and reaction rate within a tubular reactor vary with the length of the tube. Therefore, to achieve the desired effect, the tubular reactor is typically provided with a tube length that is required to satisfy the chemical reaction. In order to ensure the effect, if the existing straight tube reactor or U-shaped tube reactor needs to be internally provided with a longer tube length, the volume of the whole reactor is necessarily large enough. In addition, because the flowing state of the reactants in the reaction tube directly affects the uninterrupted mixing effect and the reaction heat transfer rate, a related design is urgently needed to avoid the excessively large volume of the reaction device, so that the purpose of improving the mixing effect and the reaction rate is achieved by changing the structure in the pipeline under the condition of ensuring that the tube length is basically unchanged.

SUMMERY OF THE UTILITY MODEL

The utility model provides a continuous flow reaction module, its tubular reactor that has relatively can reach the purpose that improves the mixed effect of continuous flow's liquid under the condition of the pipe length basic uniformity. Moreover, the continuous flow reaction module has simple structure and is convenient to manufacture, process and install. The patent also relates to a device using the continuous flow reaction module and a filling block which is arranged in the continuous flow reaction module and is used for changing the liquid flow form and the mixed flow mode.

The utility model provides a technical scheme that its technical problem adopted is: a continuous flow reaction module comprises an outer tube body and a plurality of first fillers and second fillers which are alternately fixed in the inner cavity of the outer tube body, wherein the side walls of the first fillers and the second fillers are in contact with the inner wall of the outer tube body.

One scheme commonly used in practical application is that one filling block two is correspondingly arranged in each filling block one arranged in the tube cavity of the outer tube body, so that the number of the filling blocks one arranged in the whole outer tube body is as large as or different from that of the filling blocks two by one, and meanwhile, the axial distance between the filling blocks one and the filling blocks two in the liquid flowing direction (from upstream to downstream) can be uniform and consistent, and can also be continuously increased or reduced, and the specific needs are flexibly determined according to the viscosity, the reaction condition and the like of liquid.

And the end surface of the first filling block is provided with at least one through hole which is consistent with the direction of the tube cavity of the outer tube body. And a plurality of grooves which are consistent with the direction of the tube cavity of the outer tube body are arranged on the side wall of the filling block II. After the side wall of the second filling block is contacted with the inner wall of the tube cavity of the outer tube body, the grooves in the two side walls of the filling block and the inner wall of the outer tube body enclose to form a groove hole.

After the reaction liquid flows into the pipe cavity from one end of the outer pipe body, the reaction liquid flows into a cavity formed between the first filling block and a second filling block adjacent to the downstream through a through hole arranged on the first filling block, and then is divided outwards along the radial direction by the cavity and flows downstream through grooves on two side walls of the filling block, namely enters the cavity formed between the second filling block and the first filling block adjacent to the downstream. Then the fluid flows to a cavity formed between the downstream adjacent first filling block and the downstream adjacent second filling block through the through hole of the downstream first filling block, and the circulation is carried out sequentially according to the sequence. The flow dynamics of the reaction liquid is designed, so that the reaction liquid can be continuously and fully mixed and reacted in a continuous flow by means of a convergence-dispersion rectification mode, and the aim of improving the mixing effect of the continuously flowing liquid is fulfilled. Therefore, in order to ensure that the reaction liquid circularly flows from the axis of the tube cavity to the radial outer end and then converges to the axis, and the circular flow process from the radial outer end to the radial outer end promotes the mixing effect, the position of the through hole arranged on the first filling block is suggested to be close to or at the axis of the first filling block as much as possible.

In order to accommodate as many packings as possible in the outer tube body per unit length and ensure smooth flow of the reaction solution, in the specific implementation, both end surfaces of the first packing can be in the shape of spherical grooves, and both end surfaces of the second packing can also be in the shape of spherical grooves. The arrangement can enable the cavity formed between the two opposite surfaces of the adjacent first filling block and the filling block to be in a waist drum shape, increase the volume of the cavity and facilitate the reaction liquid to be fully mixed in the process of circularly converging and dispersing flow so as to be fully reacted.

If a through hole is arranged on the first filling block, the axis of the through hole is positioned at the axis of the first filling block, and the axis of the through hole is preferably coincident with the axis of the first filling block.

If the first filling block is provided with a plurality of through holes, the following situations can be divided: (1) the axis of one through hole is positioned at the axle center of the first filling block, and other through holes are distributed on the periphery of the axle center of the first filling block; (2) all the through holes are arranged on the periphery of the axle center of the first filling block.

In the two cases, if a through hole is arranged at the axle center of the first filling block, the axle line of the through hole is along the axle center line direction of the first filling block, and the through hole does not pass through the axle center line direction of the first filling block. Meanwhile, the through holes are formed in the periphery of the axle center of the filling block, so that the axle lines of the through holes are obliquely arranged relative to the axial direction of the first filling block, and one end, located at the downstream, of the axle lines of the through holes is close to the axle center of the first filling block.

In general, the extending direction of the grooves arranged on the two side walls of the filler block is consistent with the axial lead of the filler block II, namely the projection of the extending direction (line) of the grooves on the vertical plane is relatively parallel to or coincided with the axial lead of the filler block II. However, in some embodiments, the projection of the extending direction (line) of the groove formed on the sidewall of the second filler block on the vertical plane intersects with the axis of the second filler block. The vertical plane is generally understood to be a vertical plane of the axis of the second overfeeding block, and if the vertical plane is understood to be a parallel plane relatively parallel or relatively perpendicular to the vertical plane of the axis of the second overfeeding block, the extending direction (line) of the groove and the axis of the second overfeeding block need to be projected on the vertical plane together. It is desirable that the inclination directions of the grooves formed in two adjacent packing blocks (one packing block in the middle) arranged in the same outer tube body are opposite, so as to further improve the mixing effect of the reaction liquid by continuously changing the flowing direction of the reaction liquid in the radial direction.

In other embodiments, the grooves formed on the two sidewalls of the filler block can be spiral grooves. The spiral groove is arranged to form a turbulent flow of the reaction liquid, the flow rate is increased, different components in the reaction liquid are in a certain separation state and then are gathered and mixed in the axis direction, and the purpose of further improving the mixing effect can be achieved. And the spiral directions of the grooves on two adjacent filling blocks II (the middle is provided with one filling block I) arranged in the same outer pipe body are opposite, and the aim of better improving the reaction liquid mixing effect can be fulfilled by continuously changing the rotational flow direction. It is also possible to circulate the reaction solution in such a manner that the spiral direction of the grooves in the second partial packings sequentially arranged in the flow direction of the reaction solution is the same (e.g., clockwise spiral), the spiral direction of the grooves in the second partial packings sequentially arranged next is opposite to the spiral direction of the grooves in the first partial packings (counterclockwise spiral), and the spiral direction of the grooves in the second partial packings next is opposite to the spiral direction of the grooves in the first partial packings (clockwise spiral). In the case of the partial filler one or the filler two, the number of fillers indicated by the "partial" includes the case of coincidence and also includes the case of non-coincidence. The spiral curve of the grooves with the same spiral direction may be different.

In practical implementation, if the first filling blocks have different specific structural patterns or the second filling blocks have different specific structural patterns or the first filling blocks and the second filling blocks both have different specific structural patterns, then when arranging the two filling blocks, on the premise of following the rule that one filling block is arranged every time one filling block is arranged, the specific structural patterns of the first filling blocks on both sides of the same filling block may be different, or the specific structural patterns of the second filling blocks on both sides of the same filling block may be different, or the structural patterns of the first filling blocks arranged in sequence along the flow direction of the reaction liquid are one, and the structural patterns of the first filling blocks arranged in sequence are the other, at this time, the structural patterns of the second filling blocks correspondingly arranged between the two adjacent filling blocks may be one or the other Is a plurality of; or the structural style of the second filling blocks which are sequentially arranged along the flowing direction of the reaction liquid is one, and the structural style of the second filling blocks which are sequentially arranged is another, at this time, the structural style of the first filling blocks which are correspondingly arranged between the two adjacent second filling blocks can be one or more, and the arrangement forms of the first filling blocks and the second filling blocks fall into the protection scope of the continuous flow reaction module in the patent.

In addition, (1) with respect to "including the outer tube and a plurality of fillers one and two alternately fixed in the inner cavity of the outer tube" is understood that: a. comprises the situation that one filling block II is correspondingly arranged every time one filling block I is arranged in the tube cavity of the outer tube body; b. the case where one or more second fillers are provided for each two or more first fillers provided in succession or the case where one or more first fillers are provided for each two or more second fillers provided in succession is also included. Particularly, when the specific structural style (mainly referring to the arrangement form of the through holes) of the first filling block is various, the specific structural style (mainly referring to the arrangement form of the grooves) of the second filling block is various. (2) The expression that the side wall of the second filling block is provided with a plurality of grooves which are consistent with the direction of the tube cavity of the outer tube body is understood as follows: a. the situation that the radial section of the notch which is arranged on the side surface of the second filling block is triangular, trapezoidal, U-shaped, or ] shaped or other irregular or regular shapes is not only included; b. it is also considered to include the slots of the two end faces of the conventional fillers disposed in the vicinity of the inner rings near the two side wall faces of the fillers, and the radial sectional shape of the slots includes any shape.

As shown in FIG. 1, a continuous flow reaction module comprises an outer tube body 1 and a plurality of first fillers 2 and second fillers 3 alternately fixed in the inner cavity of the outer tube body 1, wherein the side walls of the first fillers 2 and the second fillers 3 are in contact with the inner wall of the outer tube body 1. The side wall of the filling block and the inner wall of the outer tube body are tightly pressed together by adopting a hot assembly process, so that the filling block cannot move relatively in the tube cavity in use. Of course, if the outer tube body is of a structure with half tubes at two sides buckled, the side wall of the filling block and the inner wall of the outer tube body can be pressed together in a manner that the clasping hoop is arranged at the position, corresponding to the filling block, outside the outer tube body. The outer pipe body can be understood as a plurality of unit pipes which are sequentially connected together through a threaded structure or an insertion structure, and at the moment, the opposite ends of the two connected unit pipes are in accordance with the alternating arrangement rule of the first filling blocks and the second filling blocks in the whole outer pipe body. Set up into the unit form with outer body, can put convenient equipment, conveniently put into intraductal and be convenient for again hold the axial spacing between two adjacent fillers in operation with filling the piece. In the specific assembly process, the operation that the filling blocks are sequentially connected into a whole through the connecting ribs in advance and then are plugged into the outer pipe body or the unit pipe is not eliminated.

In practical implementation, as shown in fig. 1, one filling block two 3 is correspondingly arranged in each filling block one 2 arranged in the lumen of the outer tube body 1, so that the number of the filling blocks one 2 arranged in the whole outer tube body 1 is the same as that of the filling blocks two 3, or one filling block is more than one filling block or one filling block is more than two filling blocks. The axial distance between the first packing and the second packing in the liquid flowing direction (i.e. from the upstream to the downstream) can be uniform, can be continuously larger or continuously smaller, and can be even partially uniform and partially relatively larger or smaller, and the specific needs can be flexibly determined according to the viscosity, the reaction condition and the like of the liquid.

The end face of the filling block I2 is provided with at least one through hole 21 which is consistent with the direction (axial direction) of the tube cavity of the outer tube body 1. The side wall of the second filling block 3 is provided with a plurality of grooves 31 which are consistent with the direction (axial direction) of the tube cavity of the outer tube body 1. After the side wall of the second filling block 3 is contacted with the inner wall of the lumen of the outer tube body 1, the groove 31 on the side wall of the second filling block 3 and the inner wall of the outer tube body 1 enclose to form a groove hole. The through hole 21 may be a cylindrical hole as shown, or may be a conical hole, a triangular hole, a prismatic hole, a special-shaped hole, or the like. The radial cross-sectional shape of the groove 31 may be U-shaped as shown, V-shaped, trapezoidal, or spline (groove for engaging gear teeth) or the like.

As shown in fig. 1, the axial direction of the fillers 2, 3 is coincident with the axial direction of the outer tube 1. After flowing into the tube cavity from one end of the outer tube body 1, the reaction liquid flows into a cavity formed between the first filling block 2 and the second filling block 3 adjacent to the downstream through the through holes 21 arranged on the first filling block 2, and then is divided radially outwards by the cavity and flows to the downstream through the grooves 31 on the side wall of the second filling block 2, namely enters the cavity formed between the second filling block 3 and the first filling block 2 adjacent to the downstream. Then, the fluid flows from the through holes 21 of the downstream first filler piece 2 to the cavity formed between the adjacent downstream second filler pieces 3, and the circulation is performed in the above order. The flowing form of the reaction liquid is designed, so that the reaction liquid can be continuously mixed and reacted in a continuous flowing process by virtue of a rectification mode of converging towards the center and dispersing towards the periphery in the radial direction, and the aim of improving the mixing effect of the continuously flowing liquid is fulfilled. Therefore, in order to ensure the promotion effect of the mixing effect of the circulating flow process that the reaction liquid circularly disperses from the axis of the tube cavity to the radial outer end and then converges to the axis and then disperses to the radial outer end, the position of the through hole 21 arranged on the filling block I2 is suggested to be close to or at the axis of the filling block I2 as much as possible (the axial lead of the through hole is coincident with the axial lead of the filling block I shown in figure 1).

In order to accommodate as many packings as possible in the outer tube body per unit length and ensure smooth flow of the reaction solution, as shown in fig. 1 to 11, both end surfaces of the first packing 2 and both end surfaces of the second packing 3 are spherical grooves. The arrangement can enable the cavity formed between the two opposite surfaces of the adjacent first filling block and the filling block to be in a waist drum shape, increase the volume of the cavity and facilitate the reaction liquid to be fully mixed in the process of circularly converging and dispersing flow so as to be fully reacted. On one hand, the reaction liquid can be smoothly gathered to the center, and on the other hand, the reaction liquid can dispersedly climb outwards along the radial direction to a certain extent, so that part of the reaction liquid has reflux and can be continuously mixed with the liquid flowing in the back.

As shown in fig. 2, 4 and 6, one through hole 21 is provided in the axial direction of the first filler piece 2. Two end faces (A) of the first filling block 2₁Flour, A₂Face) forms a groove that is substantially uniform in arc.

As shown in fig. 3 and 5, a plurality of grooves 31 are provided alternately on the sidewall of the second filler block 3, and the direction of the grooves 31 coincides with the axial direction of the second filler block 3. As shown in fig. 7, the grooves 31 provided in the side walls are inclined, and the extensions of the inclined grooves intersect with the projection of the axial direction (line) of the second filler piece 3 in the vertical plane. Two end faces (B) of the second filling block 3₁Flour, B₂Face) forms a groove that is substantially uniform in arc.

Comparing fig. 2 and 3, the end face (a) of the first filler piece 2₁Flour, A₂Face) is formed by the arc of the groove and the end face (B) of the second filling block 3₁Flour, B₂Faces) form grooves of different arcs. In practical application, the end face (A) of the first filling block 2 can be used₁Flour, A₂Face) and end face (B) of the second filling block 3₁Flour, B₂Faces) form the same arc of the groove.

As shown in FIG. 9, B of the second filler block 3₁The surface forms a groove arc and B₂The faces form grooves of different arcs. Similarly, A of filling block one 2₁The surface forms a groove arc and A₂The arc of the groove formed by the faces may also be different.

As shown in fig. 1, 2, 4 and 6, if one through hole 21 is provided on the first filler block 2, the axis of the through hole 21 is located at the axial center of the first filler block 2, and the axis of the through hole 21 is set to coincide with the axial center of the first filler block 2.

As shown in fig. 8 and 9, the first filler block 2 is provided with a plurality of through holes, the axis of one through hole 21 is located at the axial center of the first filler block 2, and the other through holes 21 are distributed around the axial center of the first filler block to form a circle (in addition to the circle shown in the figure, the circle may be triangular, polygonal, etc.). Other through holes can be arranged in a word or arranged into a plus sign or arranged into an x sign relative to the through holes at the axle center, and the like.

In addition, if the first filling block 2 is provided with a plurality of through holes, all the through holes can be arranged on the periphery of the axis of the first filling block to form one circle or a plurality of circles, or form a triangle or form a polygon, or be arranged to form a straight line or be arranged to form a "+" sign or be arranged to form an "x" sign, and the like.

As shown in fig. 8, for the through hole 21 arranged at the periphery of the axial center of the first filler block 2, it is preferable that the axis of the through hole is inclined with respect to the axial direction of the first filler block 2 and the end of the through hole at the downstream side of the axis of the through hole is close to the axial center of the first filler block.

In general, as shown in fig. 1, 3 and 5, the extending direction of the groove 31 provided on the sidewall of the second filler block 3 is consistent with the direction of the axis of the second filler block 3, that is, the projection of the extending direction (line) of the groove 31 on the vertical plane is relatively parallel to or coincides with the axis of the second filler block 3. However, in some embodiments in practical applications, a projection of an extending direction (line) of the groove formed on the sidewall of the second filler block on a vertical plane intersects with an axial line of the second filler block (see fig. 7). The vertical plane is generally understood to be a vertical plane of the axis of the second overfeeding block, and if the vertical plane is understood to be a parallel plane relatively parallel or relatively perpendicular to the vertical plane of the axis of the second overfeeding block, the extending direction (line) of the groove and the axis of the second overfeeding block need to be projected on the vertical plane together. It is emphasized that the inclination directions of the grooves on two adjacent fillers two (one filler one in the middle) arranged in the same outer tube body can be opposite, so as to further improve the mixing effect of the reaction liquid by continuously changing the flowing direction of the reaction liquid in the radial direction.

As shown in FIG. 11, the grooves 31 formed on the side walls of the second filler block 3 can be spiral grooves. The spiral groove 31 can make the reaction liquid form turbulent flow, improve the flow velocity, make different components in the reaction liquid converge towards the axial center after being separated, and can achieve the purpose of further improving the mixing effect. And the spiral directions of the grooves on two adjacent filling blocks II (the middle is provided with one filling block I) arranged in the same outer pipe body are opposite, and the aim of better improving the reaction liquid mixing effect can be fulfilled by continuously changing the rotational flow direction.

In practical implementation, if the first filler block has a different specific structural style (e.g., fig. 2 and 8) or the second filler block 3 has a different specific structural style (e.g., fig. 3, 7, 10 and 11)), or both the first filler block and the second filler block have different specific structural styles (e.g., fig. 2, 8, 3, 7, 10 and 11)), the two filler blocks may be arranged according to the rule that one filler block is arranged for each filler block, and the specific structural styles of the first filler blocks on both sides of the same filler block may be different, or the specific structural styles of the second filler blocks on both sides of the same filler block may be different.
