Description

Technical Field

[0001] This utility model relates to the field of ultrasonic reactors, and in particular to an ultrasonic reactor, a laboratory-grade reactor, and an industrial-grade reactor. Background Technology

[0002] The working principle of an ultrasonic reactor is based on the propagation characteristics of ultrasound in liquids. It generates a series of physical effects through high-frequency vibration, which promotes chemical reactions or enables the processing of materials.

[0003] Existing ultrasonic reactors have the following structural defects: 1. Insufficient sealing: The connection between the vibrator and the reactor is poorly sealed, which can easily lead to liquid leakage or gas leakage, affecting the stability of the reaction environment.

[0004] 2. Uneven distribution of ultrasonic field: In some reactors (such as batch reactors), the ultrasonic energy is concentrated in a local area due to the fixed position of the vibrator, resulting in large differences in the intensity of the sound field inside the reactor, which affects the reaction efficiency.

[0005] 3. Existing reactors have only one series path, so the flow rate of reactants in a single continuous flow reactor is fixed. When production or experiments require increasing the flow rate of reactants, multiple continuous flow reactors can only be used to increase the flow rate. Moreover, the required reaction flow rate and reaction length are different in industrial production and experiments. When the reactants do not require an excessively long reaction length, existing continuous flow reactors, due to their non-adjustable reaction length, will result in a waste of reaction tube length. After the reactants have finished reacting, they continue to flow in the reaction tube, and excessively long reaction lengths may generate too many byproducts. Utility Model Content

[0006] In view of this, the present invention proposes an ultrasonic reactor, as well as experimental and industrial-grade reactors, aiming to solve the problems existing in the prior art.

[0007] Specifically, the ultrasonic reactor of this utility model includes: A reaction tube assembly is used to provide a reaction channel for the reaction fluid, the reaction tube assembly comprising multiple reaction tubes; A housing used for heat exchange of the reaction fluid within the reaction tube assembly; An ultrasonic generator used to provide ultrasonic waves to the reaction fluid inside the reaction tube; The ultrasonic generator includes a transducer disposed outside the housing and a vibrating rod for insertion inside the housing.

[0008] Based on the above scheme, tube sheets for fixing the reaction tubes are respectively installed at both ends of the reaction tube assembly; the tube sheets are connected to the tube box in a detachable manner.

[0009] Based on the above scheme, a flange assembly for fixing the ultrasonic generator and the tube box is also included; The flange assembly includes an upper flange that is fixedly connected to a pipe box near the ultrasonic generator and a lower flange that works in conjunction with the upper flange to fix the ultrasonic generator.

[0010] In addition, this utility model also provides an experimental-grade reactor, including: the ultrasonic reactor mentioned above; The reaction tube group consists of several reaction tubes connected in series, and the tube box is a baffle box.

[0011] Based on the above scheme, a reactant inlet for inputting the fluid to be reacted into the reaction tube group and a reactant outlet for outputting the fluid after reaction from the reaction tube group are provided on the tube box on the side away from the ultrasonic generator.

[0012] Based on the above scheme, the plurality of reaction tubes are arranged around the vibrating rod.

[0013] In addition, this utility model also provides an industrial-grade reactor, including: the ultrasonic reactor; the reaction tube assembly consists of several reaction tubes connected in parallel.

[0014] Based on the above scheme, a second manifold for collecting the input fluid to be reacted is provided on the pipe box on the side away from the ultrasonic generator and connected to the reaction pipe; the second manifold is connected to the reactant inlet.

[0015] Based on the above scheme, a first manifold for collecting the fluid after the reaction is provided on the pipe box near the ultrasonic generator; the first manifold is connected to the reactant outlet.

[0016] Based on the above scheme, the reactant outlet is located on the side wall of the tubular container.

[0017] Compared to existing devices, this invention allows for the connection of different tube boxes to the same reactor via a tube sheet. By changing the connection relationship between the tube box and the reaction tubes, the flow rate and total flow length of the reactants in a single reaction tube assembly can be altered. Furthermore, by simply changing the tube box, different reaction flow rates and lengths can be achieved for different requirements, enabling both experimental and industrial applications without the need to replace the reactor, facilitating production conversion, and reducing costs. In addition, the components and parts included in this ultrasonic reactor, as well as the experimental and industrial-grade ultrasonic reactors, are readily available and easy to assemble, resulting in low production costs.

The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Example 1

[0021] like Figure 1 As shown, this application provides a specific embodiment of an ultrasonic reactor, including: The reaction tube assembly 2 is used to provide a reaction channel for the reaction fluid, and the reaction tube assembly 2 includes multiple reaction tubes 20; The housing 1 is used for heat exchange of the reaction fluid within the reaction tube assembly 2; An ultrasonic generator 5 is used to provide ultrasonic waves to the reaction fluid in the reaction tube 20. The ultrasonic generator 5 includes a transducer 5-1 disposed outside the housing 1 and a vibrating rod 5-2 for insertion into the housing 1.

[0022] like Figure 2 As shown, specifically, tube sheets 3 for fixing reaction tubes 20 are respectively provided at both ends of the reaction tube assembly 2; the tube sheets 3 are connected to the tube box 4 in a detachable manner.

[0023] To improve the sealing between the tube sheet 3 and the tube box 4, a gasket 8 is also included between the tube sheet 3 and the tube box 4.

[0024] The ultrasonic generator 5 mentioned above can be a conventional ultrasonic generator in the prior art. Its specific structure is not an innovation of this utility model and will not be described in detail here.

[0025] In order to ensure a stable connection between the ultrasonic generator 5 and the reactor, the ultrasonic reactor described above also includes a flange assembly for fixing the ultrasonic generator 5 and the tube box 4. The flange assembly includes an upper flange 6 fixedly connected to the pipe box 4 near the ultrasonic generator 5, and a lower flange 7 used in conjunction with the upper flange 6 for fixing the ultrasonic generator 5. This design allows for a stable connection between the reactor and the ultrasonic generator 5, while also enabling rapid installation and disassembly.

[0026] Example 2

[0027] Based on the ultrasonic reactor of Example 1, such as Figure 1-4 As shown, this application provides an experimental-grade reactor for conducting exploratory experiments on chemical reactions under ultrasonic conditions in the laboratory.

[0028] The reaction tube group 2 consists of several reaction tubes 20 connected in series, and the tube box 4 is a baffle tube box; The baffle box uses patent number CN201910172116.6, patent title: "A Multi-Thread Baffle Box and Reactor", as shown below. Figures 3-4 As shown, the baffle box has several phase-separated baffle channels 40. The baffle box is detachably connected to the tube sheet 3 of the reactor. The tube sheet 3 and the baffle channels 40 of the baffle box together form several phase-separated baffle channels. Each reaction tube group 2 includes at least two reaction tubes 20. Each baffle channel 40 corresponds to and is connected to two reaction tubes 20.

[0029] The number of reaction tubes 20 in reaction tube group 2 can be adaptively selected according to needs; in use, only the above-mentioned baffle box needs to be replaced, and the correspondence between one baffle and different numbers of reaction tubes needs to be changed, thus changing the number of reaction tubes 20 in the same reaction tube group 2. Figure 3and Figure 4 The baffle box shown is used for 12 reaction tubes 20.

[0030] As a specific implementation scheme, the reaction tubes 20 are all vertically arranged straight tubes, and the upper and lower ends of each reaction tube 20 pass through and are fixedly connected to the tube sheet 3; several reaction tubes 20 are arranged around the vibrating rod 5-2.

[0031] The lower and upper parts of the shell 1 are respectively provided with a shell-side inlet 10 and a shell-side outlet 11. The shell-side interior of the shell 1 is used for the flow of heat transfer medium to maintain a suitable temperature for the reactants in the tube side of the reaction tube 20. The heat transfer medium enters through the shell-side inlet 10, making full and uniform contact with the reaction tube 20, resulting in better heat preservation. Finally, it is discharged through the shell-side outlet 11.

[0032] Specifically, in terms of the flow sequence of the medium, adjacent reaction tubes 20 are connected in series one by one through their corresponding baffle channels. On the tube box 4 on the side away from the ultrasonic generator 5, there is a reactant inlet 41 for inputting the fluid to be reacted into the reaction tube group 2 and a reactant outlet 42 for outputting the fluid after the reaction from the reaction tube group 2.

[0033] In this embodiment, during use, the reactants enter the reaction tube 20 through the reactant inlet 41. Inside the shell 1, adjacent tube holes are connected by a baffle 40. The reactants are deflected by the baffle 40 and flow back along the transport direction of the reaction tube 20, finally leaving the reaction tube 20 through the reactant outlet 42. Multiple reaction tubes inside the reactor are connected in series, thus providing a longer reaction flow (i.e., sufficient reaction time for the chemical reaction). Specifically, when the reactant inlet 41 is located on the tube box 4, the flow sequence of the reactants in the reaction tube group 2 is as follows: the reactant enters the bottom of the first reaction tube through the reactant inlet 41 on the tube box 4, passes through the first reaction tube, and enters a baffle 40 in the tube box 4 from the top of the first reaction tube (this baffle corresponds to and connects the tops of the first and second reaction tubes), then enters from the top of the second reaction tube, flows through the second reaction tube, and enters the tube box from the bottom of the second reaction tube. The reactants flow through a baffle 40 (corresponding to and connecting the bottom ends of the second and third reaction tubes) and then from the bottom end of the third reaction tube. After passing through the third reaction tube, they flow through the top end of the third reaction tube and then into another baffle 40 (corresponding to and connecting the top ends of the third and fourth reaction tubes) in the tube box 4. This continues until the reactants exit through the reactant outlet 42. It should be noted that the terms "first," "second," ... in this paragraph correspond to the flow order of the reactants; the first reaction tube is the first reaction tube through which the reactants flow.

[0034] When the tube box 4 of this utility model is in use, adjacent reaction tubes 20 in the direction of medium transmission are connected by a baffle 40. Adjacent reaction tubes 20 do not need to be connected by elbows or U-shaped tubes, nor are they limited by the radius of the bend. The spacing between reaction tubes 20 is small, the reactor volume is small, the reaction process is long, and it is not easily damaged.

[0035] Multiple reaction tubes inside the reactor are connected in series via the aforementioned baffle 40, forming a continuous flow path. This series structure significantly increases the flow path length of the reactants, thus providing sufficient reaction time for the chemical reaction and ensuring its full progress. The design of the baffle 40 not only guides the reactants to flow back along the designated path but also prevents short-circuiting or stagnation of reactants within the tubes, ensuring the uniformity and stability of the reaction.

[0036] Example 3

[0037] Based on the ultrasonic reactor in Example 1, such as Figures 5-7 As shown, this application provides an industrial-grade reactor for industrial production of chemical reactions under ultrasonic conditions.

[0038] The industrial-grade ultrasonic reactor also includes: the reaction tube group 2 consists of several reaction tubes 20 connected in parallel.

[0039] like Figure 6 As shown, a first manifold 420-1 for collecting the fluid after reaction is provided on the tube box 4 near the ultrasonic generator 5, connected to the reaction tube 20; the first manifold 420-1 is connected to the reactant outlet 42. The reactant outlet 42 is located on the side wall of the tube box 4.

[0040] like Figure 7 As shown, specifically, a second manifold 420-2 for collecting the input fluid to be reacted is provided on the pipe box 4 on the side away from the ultrasonic generator 5, which is connected to the reaction pipe 20; the second manifold 420-2 is connected to the reactant inlet 41.

[0041] Specifically, the first manifold 420-1 and the second manifold 420-2 are connected to both ends of the two reaction tube groups 2. The number of reaction tubes 20 in the reaction tube group 2 can be adaptively selected as needed.

[0042] By connecting different pairs of tube boxes 4 to the reaction tube group 2 respectively, the number of reaction tubes 20 corresponding to each reaction tube group 2 can be changed, thereby changing the reaction length and reaction flow rate of the entire reactor.

[0043] The reactants enter several reaction tubes 20 of the reaction tube group 2 from the reactant inlet 41. The flow principle of the reactants in the reactor is the same as when the reaction tube group 2 contains a single reaction tube 20. In both cases, the flow direction of the reactants in the reaction tubes 20 of the reaction tube group 2 is the same.

[0044] The reaction tube group 2 consists of several reaction tubes 20 connected in parallel. The reaction tubes 20 of the reactor are not replaced. Only by replacing different tube boxes 4, the reaction tubes 20 contained in the reaction tube group 2 are changed into multiple reaction tubes connected in parallel. This makes the flow rate of the reactor (i.e. the total flow rate of each reaction tube group 2 containing reaction tubes 20) several times that of a single reaction tube 20 (the multiple is equal to the number of reaction tubes 20).

[0045] The flow principle of reactants in the entire reactor is as follows: The reactants enter each reaction tube 20 of the same reaction tube group 2 through the reactant inlet 41. That is, when the reactant inlet 41 is provided on the tube box 4, the flow sequence of the reactants is as follows: the reactant inlet 41 on the tube box 4 enters the second manifold 420-2, enters the bottom of multiple reaction tube groups 2, passes through each reaction tube group, and enters the first manifold 420-1 from the top of the reaction tube group 2, until the reactants flow out from the reactant outlet 42. The first manifold 420-1 and the second manifold 420-2 are connected to multiple reaction tube groups 2, and the reaction tubes 20 in each reaction tube group 2 are adjacent.

[0046] In this embodiment, when the tube box is in use, adjacent reaction tubes in the direction of medium transmission are connected by a manifold 420. Adjacent reaction tubes do not need to be connected by elbows or U-shaped pipes, nor are they limited by the radius of the bend. The spacing between reaction tubes is small, the reactor volume is small, and the reaction process is long.

[0047] This application allows for the connection of different tube boxes to the same reactor via a tube sheet, thereby changing the connection relationship between the tube box and the reaction tubes, thus changing the number of reaction tubes in each reaction tube group, and consequently changing the flow rate and total flow length of the reactants in a single reaction tube group. By changing the tube box of the same reactor, the reaction flow rate and reaction length under different requirements can be met. It eliminates the need to replace the reactor, making it convenient for production conversion and cost-effective.

[0048] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
