Description

【Technical Field】 【0001】 The present invention relates to a gas-liquid mixing reactor, and particularly to a gas-liquid reaction device capable of continuously mixing gas and liquid in multiple stages. 【Background Art】 【0002】 The gas-liquid mixing reaction technology is widely used in various fields. After introducing gas and liquid into the reaction chamber, mixing and reacting them, useful solid substances can be obtained. Also, the more thoroughly the gas and liquid are mixed and the more uniform the mixing is, the more advantageous it is for the production of useful substances. 【0003】 As a conventional gas-liquid mixing reaction technology, for example, there is a configuration in which a neck or a throttle part is provided in the reaction chamber, and a pressure difference, a turbulent flow or a Venturi effect is generated by the pipe diameter difference, and suction force is applied to the gas or liquid to drive it forward. Alternatively, there is a configuration in which gas pipes or liquid pipes with different pipe diameters or numbers are designed to enhance the uniformity when the gas and liquid merge. 【0004】 However, the above mixing promotion is local and does not last. For example, after the gas and liquid pass through the neck or the throttle part, the forward driving by the suction force is lost. Also, the mixing effect is lost after the gas and liquid pass through the merging part. Although improvement is possible by extending or expanding the reaction area, the entire device becomes larger and the cost increases significantly. 【0005】 Therefore, it is an issue in the technical field to develop a "gas-liquid reaction device" that can continuously mix gas and liquid in multiple stages, improve the reaction rate, shorten the reaction time, and is small in size. 【Summary of the Invention】 【Means for Solving the Problems】 【0006】 In one embodiment, the present invention provides a gas-liquid reaction device comprising the following: A first cavity having a first open end and a first closed end parallel to the central axis and facing each other, and further having a first space, the first space communicating with the first open end, The second cavity is provided within the first space and does not come into contact with the first cavity, and has a second closed end, a second open end, a plurality of second wing pieces, a second space, an outer wall, and a plurality of through grooves (permeable grooves) facing each other.

[Modes for carrying out the invention] 【0008】 The following describes in detail the features and exemplary embodiments of each aspect of the present invention. To further clarify the object, technical solution, and effect of the present invention, the present invention will be described in more detail with reference to the accompanying drawings and specific embodiments. The embodiments described herein are for illustrative purposes only and do not limit the present invention. Those skilled in the art may implement the present invention without using some of these specific details. The following description of embodiments aims to improve understanding of the present invention by illustrating its features. 【0009】 In this specification, relational terms such as "first," "second," etc., are used to distinguish one entity or operation from another, and do not necessarily require or suggest the existence of an actual relationship or sequence between entities or operations. Furthermore, terms such as "includes" and "contains" are intended to mean non-exclusive inclusion, and a process, method, article, or apparatus that includes multiple elements may include not only those elements but also other elements not explicitly stated, or elements specific to that process, method, article, or apparatus. Unless otherwise specified, an element defined as "...includes" does not exclude the existence of additional identical elements other than that element. 【0010】 Referring to the structure of the embodiments shown in Figures 1 and 4, the gas-liquid reactor 100 of the present invention comprises a first cavity 10, a second cavity 20, a third cavity 30, and six gas advance tubes 40. In other embodiments, the number of gas advance tubes 40 can be adjusted as needed to one or more, and is not limited thereto. 【0011】 Referring to Figure 4, the first cavity 10 has a first open end 11 and a first closed end 12 that are opposite to each other and parallel to the central axis C. The second cavity 20 has a second closed end 21 and a second open end 22 that are opposite to each other and parallel to the central axis C. The third cavity 30 has a third inlet end 31 and a third outlet end 32 that are opposite to each other and communicate with each other, parallel to the central axis C. 【0012】 The central axis C penetrates through the center of the first open end 11 and the center of the first closed end 12, penetrates through the center of the second closed end 21 and the center of the second open end 22, and further penetrates through the center of the third inlet end 31 and the center of the third outlet end 32. That is, in this embodiment, the first cavity 10, the second cavity 20, and the third cavity 30 are arranged coaxially. 【0013】 Referring to FIGS. 2 to 4, the intake pipes 40 are annularly arranged and connected around the first cavity 10 at equal intervals. The intake pipe 40 is composed of a first pipe portion 41, a second pipe portion 42, and a connecting pipe portion 43. The connecting pipe portion 43 is connected to the first pipe portion 41 and the second pipe portion 42 respectively. That is, the connecting pipe portion 43 is arranged between the first pipe portion 41 and the second pipe portion 42. 【0014】 The end of the first pipe portion 41 on the side opposite to the connection end side with the connecting pipe portion 43 is the intake end 411. The end of the second pipe portion 42 on the side opposite to the connection end side with the connecting pipe portion 43 is the outlet end 421, and the outlet end 421 is connected to the first cavity 10. Thus, each intake pipe 40 communicates with the first cavity 10. As shown in FIG. 3, the axis C42 of each second pipe portion 42 is offset from the central axis C. 【0015】 The connecting pipe portion 43 is curved in an arc shape. 【0016】 As shown in FIG. 4, the axis C41 of the first pipe portion 41 is parallel to the central axis C, and a first angle θ1 greater than 0 degrees and less than 90 degrees is formed between the axis C42 of the second pipe portion 42 and the central axis C. 【0017】 A connecting member 44 is provided between each intake pipe 40 and the first cavity 10 and they are connected to each other. The connecting member 44 is flat and supports so that each intake pipe 40 does not swing during operation. 【0018】 Referring to FIGS. 1, 4, and 5, the first cavity 10 further has a first space S10. The first cavity 10 extends in a relative direction parallel to the central axis C to form a circular tubular liquid inlet pipe 13 and a circular tubular gas-liquid outlet pipe 14 respectively. 【0019】 The inner diameter of the first cavity 10 gradually decreases toward the first open end 11 and the first closed end 12, respectively, so that the first space S10 of the first cavity 10 becomes a spindle-shaped internal space. 【0020】 The fluid supply tube 13 is connected to the first open end 11. The first space S10 communicates with the external space outside the first cavity 10 via the first open end 11 and the fluid supply tube 13. On the other hand, the first closed end 12 does not communicate directly with the external space. 【0021】 Referring to Figures 4 and 6, the second cavity 20 has a second closed end 21 and a second open end 22 facing each other, parallel to the central axis C. The second cavity 20 further has a second space S20, a plurality of second wing pieces 23, a plurality of through grooves 25, and an outer wall 26. The second cavity 20 is located within the first cavity 10 and does not directly contact the first cavity 10. The outer wall 26 surrounds and defines the second space S20. 【0022】 The inner diameter of the second cavity 20 gradually decreases toward the second closed end 21 and the second open end 22, respectively, so that the second space S20 of the second cavity 20 becomes an elongated elliptical internal space. 【0023】 Referring to Figures 6 and 7, the second wing pieces 23 are provided on the outer wall 26 at equal intervals in the circumferential direction. A second arc-shaped channel 24 is formed between adjacent second wing pieces 23. Each second arc-shaped channel 24 communicates with the first open end 11. 【0024】 Referring to Figures 6 and 7, the second wing piece 23 extends in an arc from the second closed end 21 toward the second open end 22. The end of the second wing piece 23 on the second closed end 21 side is the second wing piece inlet end 231, and the end on the second open end 22 side is the second wing piece outlet end 232. When the central axis C is set perpendicular to the horizontal plane as shown in Figure 7, the projected position P231 of the second wing piece inlet end 231 is offset from the projected position P232 of the second wing piece outlet end 232. 【0025】 The width W1 of the second wing segment 23 gradually decreases from the inlet end 231 to the outlet end 232. The thickness T1 of each second wing segment 23 also gradually decreases from the inlet end 231 to the outlet end 232. 【0026】 Referring to Figures 6, 7, and 7A, the multiple through grooves 25 penetrate the outer wall 26 and are provided at equal intervals in the circumferential direction, with each through groove 25 extending in an arc from the second open end 22 toward the second closed end 21. Each through groove 25 has a first end 251 and a second end 252 facing each other, with the first end 251 located at the second open end 22. 【0027】 As shown in Figure 7A, the projected position P251 of the first end 251 of the through groove 25 is offset from the projected position P252 of the second end 252. A second angle θ2 of more than 0 degrees but less than 90 degrees is formed between the extension direction F1 of the line segment connecting the first end 251 and the second end 252 and the second open end 22. 【0028】 As shown in Figure 6, the second space S20 communicates with the first space S10 through each through groove 25. 【0029】 Referring to Figures 7 and 8, the axis C42 of each second pipe section 42 is offset from the central axis C as shown in Figure 3, and as shown in Figure 8, the axis C42 of each second pipe section 42 does not pass through each through groove 25. As a result, after the gas AR flows from the second pipe section 42 into the first cavity 10, it collides with the fence section 261 of the outer wall 26 located between two adjacent through grooves 25, creating turbulence. This prevents the gas AR from directly flowing into the second cavity 20 through the through grooves 25 before mixing with the liquid in the first cavity 10. 【0030】 Referring to Figures 9, 10, 10A, and 10B, the third cavity 30 is a hollow circular tube with a third inlet end 31 and a third outlet end 32 that are parallel to each other, facing each other and communicating, and parallel to the central axis C. The third cavity 30 is located inside the second cavity 20 and does not come into contact with the second cavity 20. The gas-liquid outlet pipe 14 is connected to the third outlet end 32. 【0031】 The third cavity 30 further has a third space S30 and a plurality of third wing pieces 33. In this embodiment, the third wing pieces 33 are arranged at equal intervals around the central axis C and are provided within the third space S30. A third arc-shaped channel 34 is formed between adjacent third wing pieces 33. 【0032】 The third wing piece 33 extends in an arc from the third inlet end 31 toward the third outlet end 32. The end of the third wing piece 33 on the third inlet end 31 side is the third wing piece inlet end 331, and the end on the third outlet end 32 side is the third wing piece outlet end 332. When the central axis C is set perpendicular to the horizontal plane as shown in Figure 10, the projected position P331 of the third wing piece inlet end 331 is offset from the projected position P332 of the third wing piece outlet end 332. 【0033】 The width W2 of the third wing 33 is constant from the inlet end 331 to the outlet end 332. The thickness T2 of each third wing 33 gradually decreases from the inlet end 331 to the outlet end 32. 【0034】 The second space S20 and the third space S30 are connected via the third arc-shaped flow path 34, and the third outlet end 32 is connected to the outside space via the gas-liquid outlet pipe 14. 【0035】 Referring to Figure 11, when the central axis C is positioned perpendicular to the horizontal plane as shown in Figure 11, and the horizontal height H11 of the first open end 11 of the first cavity 10 is higher than the horizontal height H12 of the first closed end 12, the horizontal height H21 of the second closed end 21 of the second cavity 20 is higher than the horizontal height H22 of the second open end 22, and furthermore, the horizontal height H31 of the third inlet end 31 of the third cavity 30 is higher than the horizontal height H32 of the third outlet end 32. 【0036】 Furthermore, the projection range A421 of the inner diameter of the outlet end 421, parallel to the horizontal plane, is located within the projection range A25 of the through groove 25, which is parallel to the horizontal plane. 【0037】 Furthermore, the horizontal height H232 of the second wing exit end 232 is located outside the projection range A25 parallel to the horizontal plane of the through groove 25. 【0038】 Referring to Figure 12, the process by which gas and liquid are mixed in the gas-liquid reactor 100 of the present invention will be explained. Liquid L flows from the liquid feed tube 13 to the first open end 11, then into the first cavity 10 and into each second arc-shaped flow path 24. Gas AR flows from the feed end 411 of each gas feed tube 40 to the first pipe section 41, through the connecting pipe section 43, and then into the first cavity 10 from the outlet end 421 of the second pipe section 42. Gas AR and liquid L undergo a first stage of mixing in the first space S10 of the first cavity 10 to form a first stage mixed gas-liquid AL1. 【0039】 Next, the first-stage mixed gas-liquid AL1 flows into the second space S20 of the second cavity 20 through each through groove 25 of the second cavity 20, where it undergoes a second stage of mixing to form the second-stage mixed gas-liquid AL2. 【0040】 Next, the second-stage mixed gas liquid AL2 flows from the third inlet end 31 of the third cavity 30 into the third space S30 of the third cavity 30, flows into each third arc-shaped flow path 34, undergoes the third stage of mixing, and forms the third-stage mixed gas liquid AL3. 【0041】 Next, the third-stage mixed gas-liquid AL3 flows out of the third cavity 30 from the third outlet end 32, and further flows out into the external space via the gas-liquid outlet pipe 14 for use in subsequent processes. 【0042】 As described above, the gas-liquid reaction apparatus of the present invention accelerates and sustains gas-liquid mixing through its composite cavity structure, generating turbulence, vortex, and injection effects as the fluid flows through each cavity, thereby enabling thorough and uniform mixing of the gas and the reactive components in the solution within the turbulent flow path. Since this apparatus is driven by the kinetic energy of the fluid, it does not require a stirring motor or a tank to contain the fluid, thus significantly reducing the space required for processing, the construction costs of the reactor, and motor power. Furthermore, because it can be operated continuously, it can greatly improve production capacity. 【0043】 Those skilled in the art will understand that the gas-liquid reactor of the present invention is not limited to the first, second, and third cavities of the embodiment. A fourth, fifth, or more cavities can be provided as needed, the flow paths of the gas and liquid can be extended by a multi-layered covering structure, and the flow velocities of the gas and liquid can be accelerated by the arrangement of fins. 【0044】 The above are merely specific embodiments of the present invention, and those skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope of the present invention. All of these modifications or substitutions are within the scope of protection of the present invention.
