Description

Technical Field

[0001] The present invention belongs to the field of pharmaceutical and chemical equipment, and particularly relates to a high-turbulence tubular reactor. Background Art

[0002] A tubular reactor is a continuous operation reactor in the shape of a tube with a large length-diameter ratio. It can be divided into a single-tube reactor and a multi-tube reactor according to its structure, and can be divided into a horizontal tubular reactor, a vertical tubular reactor and a coil tubular reactor according to its installation method. For example, a horizontal tubular reactor is composed of a single tube (straight tube or coil tube) continuously or multiple parallel tubes, and generally is provided with a sleeve or a shell-and-tube heat exchange device. During operation, the reactants are continuously added from one end, continuously react in the tube, and continuously flow out from the other end, thus achieving the required conversion. It is widely used in pharmaceutical and chemical production. Due to the relatively simple pipeline structure of the existing technology, the pipeline is long, the pressure drop is large, the power and heat consumption are large, there are problems such as insufficient mixing, low heat and mass transfer efficiency, too long reaction time, and low conversion rate, and its application is greatly restricted. Summary of the Invention

[0003] The purpose of the present invention is to provide a high-turbulence tubular reactor for the market, which has a scientific and reasonable structure, improves fluid mixing, saves energy consumption, reduces equipment investment, has uniform and sufficient reaction, and improves heat transfer efficiency and conversion rate.

[0004] The technical solution of the present invention is: It is composed of reaction tubes, inlet and outlet nozzles, control devices and other components, and a turbulence internal part is arranged in the reaction tube. The turbulence internal part is composed of a fixed shaft and blade turbulence parts, etc. The blade turbulence parts are fixed on the fixed shaft, and the turbulence internal part is inserted into the reaction tube, and both ends of its fixed shaft are integrally connected with the reaction tube.

[0005] Further, the blade turbulence parts have different lengths, a shaft hole is arranged at the central position, and reinforcing ribs are arranged thereon.

[0006] Furthermore, the width direction of the blade turbulence parts of the turbulence internal part can form an angle of 4-45° with the fixed shaft, or can be set to an angle of 90°, and the blade turbulence parts with different lengths are fixed on the fixed shaft.

[0007] The beneficial effects of the present invention are: Since a turbulence internal part is added in the heat exchange reaction tube, the blade turbulence parts cause obstruction to the reactants flowing through the reaction tube to form high turbulence, so that the reactants are in a high-turbulence state in the tube, the mixing is more sufficient and the reaction is more uniform. It can effectively solve the problems of large investment, high energy consumption, low conversion rate, long time, too long required pipeline, low heat transfer efficiency, etc., and is often used in occasions requiring high-efficiency heat transfer. It has the advantages of reducing costs, improving efficiency, saving energy, etc., and can be widely used in industries such as petrochemical, fine chemical, food and biopharmaceuticals.

[0010] In the figure: 1 is a reaction tube, 2 is a fixed shaft, 3 is a blade turbulent member, 4 is a reinforcing rib, and 5 is a shaft hole. Detailed Embodiment

[0011] As Figure 1 , Figure 2 shown, a strong-turbulence tubular reactor is composed of components such as a reaction tube 1, inlet and outlet nozzles, and a control device. A turbulent internal part is arranged in the reaction tube 1. The turbulent internal part is composed of a fixed shaft 2 and a blade turbulent member 3, etc. The lengths of the blade turbulent members 3 are different. A shaft hole 5 is arranged at the central position, and a reinforcing rib 4 is arranged thereon. The blade turbulent member 3 is fixed on the fixed shaft 2. The included angle between its width direction and the fixed shaft 2 can be set to 4 - 45° (as Figure 3 , Figure 4 shown), or can be set to 90° (as Figure 5 shown). The turbulent internal part is inserted into the reaction tube 1, and both ends of its fixed shaft 2 are integrated with the reaction tube 1. When implementing the present invention, a mixing material adding nozzle can also be installed before the inlet of the material, which is suitable for the reaction of various materials. After the materials are mixed, they are pumped into the reaction tube 1 of the reactor from the inlet of the reaction tube by a material pump. At the same time, a heat source (such as heat-conducting oil or steam, etc.) is sent into the jacketed heat exchange tube 2 outside the reaction tube 1, so that the reactants in the reaction tube 1 exchange heat with the heating medium in the jacketed heat exchange tube 2. After the heat exchange, the temperature of the reactants in the reaction tube 1 rises to the set process temperature. The reactants in the reaction tube 1 are in a strong-turbulence state due to the blocking of the blade turbulent member 3 at the set temperature, so that the reactants are turbulized more intensively in the tube, the mixing inside the fluid is enhanced, and the heat transfer efficiency and conversion rate are improved. It has the advantages of low cost, high efficiency, energy saving, etc., and can be widely applied to industries such as petrochemical industry, fine chemical industry, food, and biopharmaceuticals.
