Description

Technical Field

[0001] This utility model relates to the field of pipeline reactors, and in particular to a novel pipeline reactor. Background Technology

[0002] In the chemical and pharmaceutical industries, the application of pipeline reactors is constantly expanding, especially suitable for continuous production reaction processes and reactions involving flammable, explosive, or corrosive hazardous materials. Currently, most pipeline reactors have no internal components. Some pipeline reactors have baffles or other measures to increase disturbance. However, because the pipe diameter of pipeline reactors is generally limited by production scale and flow rate, the installation of baffles and other internal components has limitations, resulting in high manufacturing difficulty, inconvenient installation, and the need to improve the mixing effect of different reaction media. Traditional empty tube reactors have at least the following drawbacks: Traditional empty tube reactors have poor mixing of reaction media or liquids and cannot effectively transfer mass. They require long pipelines to achieve the required degree of mixing, which leads to longer reaction times, increases the length of the pipeline reactor, and may even affect the reaction yield. Some pipeline reactors have been equipped with measures to increase turbulence and enhance the turbulence effect, but this will greatly increase the resistance of the entire pipeline reactor, requiring more power and increasing energy consumption. Most mixing elements need to be welded or permanently fixed inside the pipeline, making cleaning difficult. Once internal blockages occur or replacement is needed, the pipeline may even need to be cut, resulting in high maintenance costs and long downtime. At the same time, pipeline reactors with special structures are difficult to manufacture. Utility Model Content

[0003] (a) Technical problems to be solved To address the aforementioned problems in the prior art, this utility model provides a novel pipeline reactor.

[0004] (II) Technical Solution To achieve the above objectives, the main technical solutions adopted by this utility model include: A novel pipeline reactor includes a pipeline unit, a support frame, a main shaft, and guide vanes; Both ends of the main shaft are mounted inside the pipe unit via the support frame; Multiple guide vanes are provided and are installed at equal intervals on the main shaft. Multiple guide holes are evenly distributed on the surface of the guide vanes.

[0005] Preferably, the guide vanes are three-bladed propellers.

[0006] Preferably, the guide vane includes a first guide vane and a second guide vane, wherein the tilt angle of the first guide vane is 30-45° and the tilt angle of the second guide vane is 45-60°.

[0007] Preferably, adjacent pipe units are connected by flanges.

[0008] Preferably, one end of the spindle is provided with a mating spline, and the other end of the spindle is provided with a mating keyway corresponding to the mating spline.

[0009] Preferably, the connection between the main shaft and the support frame is via a bearing.

[0010] (III) Beneficial Effects The beneficial effects of this invention are as follows: the perforated guide vane design combines three mixing mechanisms—diversion, shearing, and eddy current—significantly improving mass transfer, reaction rate, and efficiency. It is particularly suitable for reactions that produce excessive byproducts due to prolonged reaction times. The guide vanes have a certain angle and curved surface, which guides the fluid to flow in a specific direction, resulting in relatively low resistance and reduced energy consumption. Furthermore, this novel pipeline reactor is composed of various small units, and the modular design allows for "disassembly, cleaning, and replacement," reducing maintenance costs and downtime. It is especially suitable for the production of fine chemicals that are prone to clogging and produce a wide variety of products. Attached Figure Description

[0013] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] Please refer to Figure 1 This utility model provides a novel pipeline reactor, including a pipeline unit 1, a support frame 3, a main shaft 2, and guide vanes; The two ends of the main shaft 2 are installed inside the pipe unit 1 via the support frame 3; Multiple guide vanes are provided and are installed on the main shaft 2 at equal intervals. Multiple guide holes are evenly distributed on the surface of the guide vanes. In use, two or more reactants enter the pipe unit 1 respectively, where they begin to mix and react on the guide vanes. Each guide vane has uniformly distributed guide holes. When the fluid passes through, part of it is guided by the guide vanes to rotate, while the other part passes through the guide holes at high speed and collides and shears with the main fluid, thereby generating multiphase flow in a very short time, achieving rapid and uniform mixing and reaction of the materials, and finally obtaining a high-quality product.

[0015] In this embodiment, the guide vanes are three-bladed propellers.

[0016] In this embodiment, the guide vane includes a first guide vane 4 and a second guide vane 5, wherein the tilt angle of the first guide vane 4 is 30-45° and the tilt angle of the second guide vane 5 is 45-60°. The first guide vane 4 has a smaller inclination angle and is mainly used to initially guide the fluid, generating gentle turbulence. The second guide vane 4 has a larger inclination angle and is used to create stronger disturbances and eddies. This alternating arrangement can form staggered flows and improve mixing uniformity.

[0017] In this embodiment, adjacent pipe units 1 are connected by flanges.

[0018] In this embodiment, one end of the main shaft 2 is provided with a mating spline, and the other end of the main shaft 2 is provided with a mating keyway corresponding to the mating spline. When adjacent pipe units 1 are connected, the main shafts 2 are simultaneously connected through the mating spline and the mating keyway.

[0019] In this embodiment, the connection between the main shaft 2 and the support frame 3 is achieved through a bearing.

[0020] The working principle of this utility model is as follows: Two or more reactants enter the pipeline unit 1 respectively, where they begin to mix and react on the guide vanes. Each guide vane has uniformly distributed guide holes. When the fluid passes through, part of it is guided by the guide vanes to rotate, while the other part passes through the guide holes at high speed and collides and shears with the main fluid, thereby generating multiphase flow in a very short time, achieving rapid and uniform mixing and reaction of the materials, and finally obtaining a high-quality product.

Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
