Description

Technical Field

[0001] This invention relates to the field of reactor technology, and more specifically to a reactor with a fluid dynamics structure. Background Technology

[0002] Currently, traditional metal reactors are insufficient in terms of corrosion resistance and are difficult to operate stably for a long time in highly corrosive environments such as strong acids and strong alkalis. In contrast, non-metallic reactors have excellent corrosion resistance and are suitable for use in highly corrosive media. However, the structural design of traditional non-metallic reactors is often relatively simple, with smooth internal walls, resulting in poor fluid turbulence and low heat exchange efficiency. Therefore, there is still a large technological gap in non-metallic materials for achieving efficient heat transfer structures. Summary of the Invention

[0003] The purpose of this invention is to provide a reactor with a fluid dynamic structure that can effectively increase the heat transfer area and fluid flow dynamics, create turbulence, significantly improve heat transfer efficiency, not only have good corrosion resistance, but also provide near-high heat exchange efficiency in highly corrosive environments.

[0004] According to the present invention, a fluid dynamic structure reactor includes a reactor shell, the reactor shell having a first end and a second end opposite to each other, the first end and the second end of the reactor shell having a first material inlet and a first material outlet respectively, end caps being installed inside the reactor shell near both ends of the reactor shell, with buffer spaces left between the end caps and the ends of the reactor shell respectively, multiple pipes being installed inside the reactor shell, each pipe having both ends connected to the end caps, and a reaction space between two end caps, a second material inlet and a second material outlet being provided on the side wall of the reactor shell, the second material inlet and the second material outlet communicating with the reaction space, and continuous spiral grooves being provided on the inner wall of the pipes.

[0005] In practical use, the second material inlet of the reactor can be used to introduce various reaction fluids into the reaction space for mixing and reaction, while the first material inlet introduces heat exchange fluid into the pipeline to exchange heat between the reaction space and the pipeline. Of course, the reactor can also be used as a heat exchanger on its own, that is, different fluids can be introduced into the first and second material inlets for heat exchange. In both of the above processes, the spiral grooves set in the pipeline are a fluid dynamics design that improves the flow dynamics and turbulence effect of the fluid.

[0006] Furthermore, the central axis of the reactor shell is parallel to the line connecting the first end and the second end of the reactor shell, and baffles are spirally installed circumferentially from the first end to the second end of the reactor shell with the central axis of the reactor shell as the center line.

[0007] The spiral baffles installed inside the reactor shell can improve the flow dynamics and turbulence of the fluid entering the reaction space, and use the thrust of the fluid to minimize the accumulation of dirt.

[0008] Furthermore, the first material inlet is connected to a fluid power conveying device.

[0009] Furthermore, the fluid power conveying device includes a connecting pipe, a first end of which is connected to a pump, a second end of which is connected to the first material inlet, and a feeding port extending from the connecting pipe.

[0010] Furthermore, a tube sheet is installed in the buffer space, the shape of which is adapted to the buffer space. The tube sheet has channels along the central axis of the reactor shell, and both ends of each tube are connected to the corresponding channel.

[0011] Furthermore, the outer wall of the pipe is provided with grooves.

[0012] Furthermore, the grooves are continuously distributed on the outer wall between the two ends of the pipe.

[0013] The presence of continuous grooves causes periodic disturbances in the fluid as it flows through the outer wall of the pipe. These disturbances help break the fluid boundary layer, enhance turbulence, and thus improve the convective heat transfer coefficient. In effect, it increases the surface area of ​​the outer wall of the pipe, providing more contact surface for heat transfer and thus improving heat transfer efficiency. For example, in the condensation heat transfer process, the grooves can guide the condensate to fall off quickly along the grooves, reduce the thickness of the liquid film on the pipe wall, reduce thermal resistance, and improve the condensation heat transfer coefficient.

[0016] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0017] Combination Figure 1 The present invention illustrates a reactor with a fluid dynamic structure, comprising a reactor shell 1, wherein the reactor shell 1 has a first end and a second end opposite to each other, the first end and the second end of the reactor shell 1 are respectively provided with a first material inlet 2 and a first material outlet 3, and end caps are respectively installed inside the reactor shell 1 near the two ends of the reactor shell, with a buffer space 4 left between the end caps and the ends of the reactor shell 1, and multiple pipes 5 are installed inside the reactor shell 1, the two ends of each pipe 5 being connected to the end caps respectively, and the space between two end caps is a reaction space, a second material inlet and a second material outlet are provided on the side wall of the reactor shell, the second material inlet and the second material outlet are connected to the reaction space, and the inner wall of the pipe 5 is provided with continuous spiral grooves 10.

[0018] In practical use, the second material inlet of the reactor can be used to introduce various reaction fluids into the reaction space 6 for mixing and reaction, while the first material inlet 2 introduces heat exchange fluid into the pipe 5 to exchange heat between the reaction space 6 and the pipe 5. Of course, the reactor can also be used as a heat exchanger on its own, that is, the first material inlet 2 and the second material inlet can be used to introduce different fluids for heat exchange. In the above two processes, the design of the spiral groove 10 greatly improves the flow dynamics and turbulence effect of the fluid.

[0019] It is worth noting that turbulence refers to a situation where, when the fluid velocity increases to a certain level, streamlines in the flow field become indistinguishable, vortices appear, laminar flow is disrupted, and not only does sliding occur between adjacent flow layers, but mixing also occurs. At this time, the fluid undergoes irregular movement. The spiral groove 10 provided in the pipe 5 of this invention can accelerate the formation of turbulence. During the formation of turbulence, various forces are generated, including its own inertial force, centrifugal force, etc., which will scour the channel of the spiral groove 10 to minimize scaling and achieve a self-cleaning effect.

[0020] It is worth noting that the connection between the two walls of the spiral groove 10 in this invention is arc-shaped. This design is more resistant to scaling on the wall than the conventional design with sharp corners, and the arc shape can better exert the self-cleaning effect of turbulence.

[0021] The central axis of the reactor shell 1 is parallel to the line connecting the first end and the second end of the reactor shell 1. Spiral baffles 7 are installed circumferentially from the first end to the second end of the reactor shell along the central axis of the reactor shell 1.

[0022] The spiral baffles installed inside the reactor shell 1 can improve the flow dynamics and turbulence effect of the fluid entering the reaction space 6, and use the thrust of the fluid to minimize the accumulation of dirt.

[0023] The spiral baffle 7 can also improve the turbulence effect of the fluid in the reaction space 6.

[0024] The first material inlet 2 is connected to a fluid power conveying device.

[0025] The fluid power conveying device includes a connecting pipe, the first end of which is connected to a pump, the second end of which is connected to a first material inlet 2, and a feeding port extending from the connecting pipe.

[0026] A tube sheet 8 is installed in the buffer space 4. The shape of the tube sheet 8 is adapted to the buffer space 4. The tube sheet 8 has channels opened along the central axis of the reactor shell. The two ends of each pipe 5 are connected to the corresponding channels.

[0027] The outer wall of pipe 5 is provided with grooves 9.

[0028] The grooves 9 are distributed continuously on the outer wall between the two ends of the pipe 5.

[0029] Of course, there are many ways to set the groove pattern 9, such as Figure 2 As shown, the grooves 9 are in a continuous spiral shape, which can improve the turbulence effect and enhance the self-cleaning ability. Of course, as... Figure 3 As shown, groove 9 can also be a straight groove parallel to the axis of pipe 5 to improve heat exchange efficiency.

[0030] The presence of continuous grooves 9 causes periodic disturbances in the fluid as it flows through the outer wall of the pipe. These disturbances help break the fluid boundary layer, enhance turbulence, and thus improve the convective heat transfer coefficient. In effect, it increases the surface area of ​​the outer wall of the pipe, providing more contact surface for heat transfer and thus improving heat transfer efficiency. For example, in the condensation heat transfer process, the threaded grooves can guide the condensate to fall off quickly along the grooves, reduce the thickness of the liquid film on the pipe wall, reduce thermal resistance, and improve the condensation heat transfer coefficient.

[0031] It is worth noting that the pipe 5 described in this invention is made of non-metallic materials rather than conventional metallic materials. Therefore, it cannot be manufactured using conventional metal pressing, cutting, or other methods. Furthermore, in reactors or other related fields, the pipe 5 typically needs to meet large-size requirements. Therefore, its manufacturing process includes the following steps: S1: Provide tubular straight groove molds and materials for manufacturing; S2: Install a heating jacket on the outside of the mold to heat the mold to its initial temperature; S3: Use an extruder to evenly feed the material into the mold and heat it; S4: The mold rotates around its own axis, and at the same time, the spiral groove mandrel is slowly fed into the mold, and the material is gradually formed into a tubular shape by squeezing it outwards. S5: The continuous extrusion of the spiral groove mandrel eventually forms a continuous spiral groove on the inner wall and grooves on the outer wall, and finally the finished product is extruded. S6: Cool the finished product to room temperature; S7: Perform heat treatment on the finished product.

[0032] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
