Abstract
Description
Technical Field
[0001] This invention relates to the field of microchannel reactor technology, and in particular to a high-efficiency mixing microchannel reactor. Background Technology
[0002] Continuous flow technology, as one of the methods for drug production, typically utilizes microchannel reactors to complete the drug production process. However, traditional microchannel reactors suffer from poor mixing and insufficient temperature control stability during continuous production. Specifically, in traditional reactors, material mixing relies primarily on the reactor's channel design, resulting in limited mixing effectiveness and affecting reaction uniformity and product quality; therefore, improvements are needed. Utility Model Content
[0003] Therefore, it is necessary to provide a highly efficient mixing microchannel reactor to address the above problems.
[0004] A high-efficiency mixing microchannel reactor includes several reaction units and a base. The base has a feed channel and a discharge channel arranged side-by-side. The reaction units are spaced apart and connected side-by-side between the feed channel and the discharge channel. The feed channel is connected to the discharge channel through the reaction units. Optical modules are provided on both sides of each reaction unit. Each reaction unit includes a shell, a spiral channel, and a vibrator. The shell is connected to the base. The two sides of the shell are made of a light-transmitting material. The spiral channel is installed inside the shell, with its two ends connected to the feed channel and the discharge channel, respectively. The vibrator is installed inside the spiral channel and is fitted against it.
[0005] Preferably, the vibrator includes a pipe network and a vibrator body. The pipe network is made of woven metal wire, and the vibrator body is installed inside the pipe network and is fitted with the spiral channel through the pipe network.
[0006] Preferably, the two sides of the outer casing are made of glass plates.
[0007] Preferably, the reaction unit further includes a temperature control plate, which is installed inside the housing and located on the upper and lower sides of the spiral channel.
[0008] The advantages of this invention are: the designed spiral channel can extend the material path without increasing the length of the reaction unit, effectively improving the mixing efficiency, and the vibrator is designed to enhance the fluid mixing effect through the spiral channel.

[0011] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0012] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.
[0013] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0014] like Figures 1-2As shown, a high-efficiency mixing microchannel reactor includes several reaction units 1 and a base 2. A feed channel 21 and a discharge channel 22 are arranged side-by-side on the base 2. Several reaction units 1 are spaced apart and connected side-by-side between the feed channel 21 and the discharge channel 22. The feed channel 21 is connected to the discharge channel 22 through the reaction units 1. Optical modules 3 are arranged on both sides of each reaction unit 1. Each reaction unit 1 includes a shell 11, a spiral channel 12, and a vibrator 13. The shell 11 is connected to the base 2. Both sides of the shell 11 are made of a light-transmitting material. The spiral channel 12 is installed inside the shell 11, and its two ends are connected to the feed channel 21 and the discharge channel 22, respectively. The vibrator 13 is installed inside the spiral channel 12 and is fitted to it. Specifically, in this embodiment, the feed channel 21 and discharge channel 22 on the base 2 are metal pipes. Fluid materials are pumped into the reaction unit 1, and then enter the spiral channel 12. The spiral channel 12 we designed extends the material path as much as possible without increasing the length of the reaction unit 1. Furthermore, the spiral channel 12 forces the fluid to generate centrifugal force as it flows within it. This centrifugal force drives the fluid to generate turbulence, breaking the laminar flow state and enabling efficient three-dimensional mixing of the fluid within the spiral channel 12, effectively improving mixing efficiency. Simultaneously, the spiral channel 12 provides installation space for the vibrator 13, allowing it to be installed within the spiral channel 12, avoiding the risk of the vibrator 13 blocking the light from the optical module 3 if installed on either side of the spiral channel 12. The vibrator 13 is specifically added to improve the mixing effect of the fluid materials passing through the spiral channel 12. The vibrator 13 is an electrically driven ultrasonic vibrator, which is existing technology and will not be elaborated upon here. The vibration adjustment strategy for vibrator 13 is as follows: for example, for materials with high viscosity, the power and frequency of the ultrasound can be appropriately increased to enhance the mixing effect; while for materials with larger particles, the power and frequency of the ultrasound can be reduced to avoid excessive material breakage. The optical module 3 provides sufficient light energy to the fluid passing through the spiral channel 12. The light energy directly acts on the reactant molecules within the spiral channel 12, catalyzing them into chemical energy through photon energy, driving reaction pathways that are difficult to achieve through traditional thermodynamics, such as photopolymerization and photodegradation, thus realizing the synergistic effect of light energy and microchannel reaction synthesis. The outer shell 11 we designed is transparent on both sides, specifically made of transparent plastic or glass. The optical module 3 is installed on both sides of the reaction unit 1, providing light energy to the material flowing within the spiral channel 12. The light energy directly acts on the reactant molecules within the microchannel, converting them into chemical energy through photon energy, driving reaction pathways that are difficult to achieve through traditional thermodynamics, such as photopolymerization and photodegradation.
[0015] like Figure 2As shown, the vibrator 13 includes a tubular network 131 and a vibrator body 132. The tubular network 131 is made of woven metal wire, and the vibrator body 132 is installed inside the tubular network 131 and fits into the spiral channel 12 through the tubular network 131. Specifically, the vibrator body 132 is installed using the tubular network 131. The tubular network 131 is made of woven metal wire and has a certain degree of elasticity. After the vibrator body 132 is filled inside the tubular network 131, it transmits vibration energy through the fitting fit between the tubular network 131 and the spiral channel 12. Furthermore, the tubular network structure allows light to pass through, reducing the light resistance to the optical module 3.
[0016] Specifically, the outer shell 11 is made of glass plates on both sides, which have good light transmittance, ensuring that the light from the light module 3 can pass through the outer shell 11 and enter the reaction unit 1 to activate the photocatalyst and ensure smooth photoreaction within the spiral channel 12.
[0017] like Figure 2 As shown, the reaction unit 1 also includes a temperature control plate 14, which is installed inside the housing 11 and located on the upper and lower sides of the spiral channel 12. Specifically, a temperature sensor is also installed inside the housing 11 to detect the temperature inside the housing 11 in real time. If the temperature is lower than the preset temperature, the background controller can control the temperature control plate 14 to generate heat, specifically by heating with an electric heating wire, to increase the temperature inside the housing 11, so that the material passing through the spiral channel 12 is within the optimal temperature range, avoiding thermal deactivation or the generation of by-products.
[0018] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
