[0002] In continuous flow reactions in chemical and pharmaceutical industries, single-tube reactors are widely used due to their simple structure and ease of scalability. However, in traditional single-tube reactors, the fluid is mainly laminar, making it difficult for materials to mix sufficiently in the radial direction, resulting in inadequate contact of reactants and low reaction efficiency.
[0003] Therefore, how to avoid insufficient radial mixing of materials in a single-tube reactor, which leads to low reaction efficiency, is a technical problem that urgently needs to be solved by those skilled in the art.
[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0021] The dynamic turbulence unit is adapted to convert energy waves into radially coupled vibrations, enabling radial mixing of the fluid within the reaction tube.
[0022] In one alternative embodiment, the dynamic turbulence unit includes an elastic element located within the interlayer space, the elastic element being continuously spirally wound around the outer wall of the reaction tube.
[0023] In one alternative embodiment, the energy coupling device includes an ultrasonic generator and an acoustic coupling adhesive layer;

[0027] The beneficial effects of this invention are as follows: This single-tube reactor incorporates an ultrasonic generator mounted on the wall of the outer tube, which inputs energy waves into the reaction tube, inducing cavitation in the fluid and causing fluid particles to break down to the micrometer level before remixing. Furthermore, an elastic element spirally wound around the wall of the reaction tube converts the ultrasonic energy into radially coupled vibrations, directly disturbing the boundary layer fluid and achieving radial mixing within the reaction tube.

[0041] Research has revealed the following drawbacks of existing technologies: the fluid in traditional single-tube reactors is predominantly laminar, making it difficult for materials to mix sufficiently in the radial direction, resulting in inadequate contact of reactants and low reaction efficiency.
[0042] Based on the above research, this disclosure provides a single-tube reactor that utilizes the synergistic effect of a spiral elastic element and an ultrasonic generator to periodically agitate the fluid in the reaction tube, thereby ensuring thorough mixing of the fluid in the radial direction and solving the aforementioned problems.
[0043] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.
[0044] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0045] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0046] See Figure 1 This disclosure provides a single-tube reactor, comprising: a reaction tube 100, with a fluid inlet 110 and a fluid outlet 120 at its two ends, respectively. An outer tube 200 is fitted over the outer wall of the reaction tube 100, and the gap between the outer tube 200 and the reaction tube 100 forms a closed interlayer space 300. An elastic element 510 is disposed within the interlayer space 300, and the elastic element 510 is continuously spirally wound around the outer wall of the reaction tube 100. A plurality of ultrasonic generators 410 are also disposed on the outer wall of the outer tube 200, the ultrasonic generators 410 being adapted to input energy waves into the reaction tube 100, thereby inducing a cavitation reaction in the fluid, causing the fluid particles to break down to the micrometer level and then remix, thus promoting the mixing of the fluid in the radial direction.
[0047] See also Figure 1 Furthermore, the elastic element 510 is made of a shape memory alloy (such as a nickel-titanium alloy), and it is coiled in a spiral structure around the wall of the reaction tube 100. When the energy wave emitted by the ultrasonic generator 410 is transmitted to the elastic element 510, the geometric characteristics of the spiral structure convert the energy wave into a radial force, such as... Figure 1As indicated by arrow F1, the elastic element 510 impacts the wall of the reaction tube 100 under radial force. Subsequently, the elastic element 510 undergoes periodic expansion and contraction deformation under the reaction force F2 from the tube wall, driving the wall of the reaction tube 100 to vibrate radially. This disturbs the boundary layer fluid inside the reaction tube 100, enabling radial mixing of the fluid within the reaction tube 100. Through the synergistic effect of the elastic element 510 and the ultrasonic generator 410, the low reaction efficiency caused by insufficient radial mixing of the fluid inside the reaction tube 100 is avoided.
[0048] See Figure 1 and Figure 2 In some embodiments, mounting bases 600 are provided on both sides of the outer tube 200, and the ultrasonic generator 410 is mounted on the tube wall of the outer tube 200 through the mounting bases 600; and an acoustic coupling adhesive layer 700 is filled between the emitting end face of the ultrasonic generator 410 and the outer tube 200. Tiny irregularities on the surface of the outer tube 200 may trap air, and sound waves encountering these air pockets will be completely reflected, resulting in a significant loss of sound wave energy. The acoustic coupling adhesive layer 700 can fill these gaps and reduce sound wave reflection.
[0049] See also Figure 1 In some embodiments, the ultrasonic generators 410 are arranged along the axial direction of the reaction tube 100 and are uniformly arrayed on the wall of the outer tube 200. The uniformly arranged ultrasonic generators 410 enable the ultrasonic energy to form an equally spaced standing wave field in the axial direction of the reaction tube 100, eliminating energy dead zones.
[0050] See also Figure 1 In some embodiments, the outer tube 200 is provided with an inlet pipe 210 and an outlet pipe 220 suitable for the passage of cooling medium, and both the inlet pipe 210 and the outlet pipe 220 are in communication with the interlayer space 300. Through the cooperation of the inlet pipe 210, the outlet pipe 220 and the cooling medium in the interlayer space 300, the fluid in the reaction tube 100 can be prevented from overheating due to the vibration of the elastic element 510.
[0051] See also Figure 1 Some embodiments also provide a single-tube reactor, including: a reaction tube 100, with a fluid inlet 110 and a fluid outlet 120 at its two ends; an outer tube 200, sleeved on the outer wall of the reaction tube 100, forming a closed interlayer space 300 between the reaction tube 100 and the outer tube 200; an energy coupling device 400, disposed on the outer wall of the outer tube 200, for transmitting energy waves to a dynamic turbulence unit 500; the dynamic turbulence unit 500, disposed within the interlayer space 300, for converting the energy waves into radially coupled vibrations; wherein, the dynamic turbulence unit 500 is adapted to convert the energy waves into radially coupled vibrations, thereby achieving radial mixing of the fluid within the reaction tube 100.
[0052] See also Figure 1In some embodiments, the dynamic turbulence unit 500 includes an elastic element 510 located within the interlayer space 300, the elastic element 510 being continuously spirally wound around the outer wall of the reaction tube 100.
[0053] See also Figure 1 In some embodiments, the energy coupling device 400 includes an ultrasonic generator 410 and an acoustic coupling adhesive layer 700; the acoustic coupling adhesive layer 700 is disposed between the ultrasonic generator 410 and the outer tube 200; and the ultrasonic generator 410 is disposed along the axial direction of the reaction tube 100 and is uniformly arranged in an array on the tube wall of the outer tube 200.
[0054] In summary, this single-tube reactor utilizes an ultrasonic generator 410 mounted on the wall of the outer tube 200. This generator inputs energy waves into the reaction tube 100, inducing cavitation in the fluid and causing fluid particles to break down to the micrometer level before remixing. Furthermore, an elastic element 510 spirally wound around the wall of the reaction tube 100 converts the ultrasonic energy into radially coupled vibrations, directly disturbing the boundary layer fluid and achieving radial mixing within the reaction tube 100. Through the synergistic effect of the elastic element 510 and the ultrasonic generator 410, the reactor avoids the low reaction efficiency caused by insufficient radial mixing of the fluid within the reaction tube 100.
[0055] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0056] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.
[0057] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.
[0058] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.
[0059] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
