[0034] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0035] Please refer to Figure 1-Figure 4 A tubular reactor comprises a tube body 1 and a first baffle assembly 2 and a second baffle assembly 3 sequentially arranged along the axis of the tube body 1; the tube body 1 has a liquid inlet 11, a liquid outlet 12 and a reaction chamber 13; the tube body 1, the first baffle assembly 2 and the second baffle assembly 3 are coaxially arranged, and the first baffle assembly 2 and the second baffle assembly 3 are located in the reaction chamber 13; the first baffle assembly 2 has at least three first flow holes 21 uniformly distributed around the axis of the tube body 1; the second baffle assembly 3 has a second flow hole 30 coaxially arranged with the axis of the tube body 1; the liquid inlet 11 is connected to the liquid outlet 12 through the first flow hole 21 and the second flow hole 30.

[0036] It can be understood that by setting the first baffle assembly 2 and the second baffle assembly 3 and forming the first flow hole 21 and the second flow hole 30, the length of the reaction channel can be extended, thereby shortening the length of the tube body 1, and due to the setting of the first flow hole 21 and the second flow hole 30, the flow pressure of the reaction liquid is increased, further improving the reaction efficiency of the reactants. The utility model adopts a method of increasing the length of the reaction channel inside the tube body 1, ensuring that the reactants react fully and improving the reaction efficiency of the reactants without increasing the length of the tube body 1.

[0037] In some embodiments, the first baffle assembly 2 includes a first baffle ring 22 and a first baffle plate 23 which are coaxially arranged; the first baffle plate 23 is arranged on the axial end surface of the first baffle ring 22 and forms a first flow hole 21 with the inner wall of the first baffle ring 22. In the axial direction of the tube body 1, the first baffle plate 23 is centrally arranged relative to the first baffle ring 22.

[0038] In some embodiments, the first baffle 23 includes a circular portion 231 and at least two extension portions 232; all the extension portions 232 are equally spaced around the circular portion 231, and the extension portions 232 are radially distributed along the circular portion 231; preferably, four extension portions 232 are provided to form four first flow holes 21. The arrangement of the extension portions 232 and the circular portion 231 can enclose the inner wall of the first baffle ring 22 to form the first flow holes 21, so that the solution flows into the space formed between the first baffle 23 and the second baffle assembly 3 after being diverted by the first baffle 23, and is gathered through the second flow holes 30 on the second baffle assembly 3, so that the solution is first diverted and then mixed, which prolongs the length of the reaction channel and has a pressurizing effect on the reactants.

[0039] In some embodiments, the second baffle assembly 3 includes a coaxially arranged second baffle ring 31 and a second baffle plate 32; the second baffle plate 32 is arranged on the axial end face of the second baffle ring 31, and in the axial direction of the second baffle ring 31, the second baffle second flow hole 30 is opened on the second baffle plate 32. Preferably, the second baffle plate 32 is in a circular ring shape, the axial thickness of the first baffle ring 22 and the second baffle ring 31 are equal, and the first baffle ring 22 and the second baffle ring 31 are pressed against each other in the axial direction, which is used to limit the adjacent first baffle plates 23 and the second baffle plates 32 to maintain an equal distance, so that the pressure difference of the reactants between the first baffle plates 23 and the second baffle plates 32 will not produce excessive fluctuations. Among them, the first baffle plate 23 and the second baffle plate 32 are respectively clamped between the corresponding first baffle ring 22 and the second baffle ring 31 in the axial direction.

[0040] In some embodiments, at least four first deflector assemblies 2 and second deflector assemblies 3 are respectively provided, and the number of first deflector assemblies 2 and second deflector assemblies 3 is set according to the length of the tube body 1, and the last deflector assembly at the liquid outlet end of the tube body 1 should be the second deflector assembly 3 to ensure that the reactants are gathered and discharged from the second flow hole 30, thereby improving the discharge smoothness.

[0041] In some embodiments, the tube body 1 has a liquid inlet channel 14 and a liquid outlet channel 15; in the liquid inlet direction, the inner diameter of the liquid inlet channel 14 gradually increases, slowing down the flow rate of the solution entering the reaction chamber 13, and the inner diameter of the liquid outlet channel 15 gradually decreases, which has a pressurizing effect on the reaction liquid.

[0042] In some embodiments, in order to ensure that the reactants can form a concentrated reaction liquid and be discharged after being diverted, the last baffle assembly arranged near the liquid outlet 12 is a second baffle assembly 3, and a sealing ring 4 is sandwiched between the second baffle assembly 3 near the liquid outlet 12 and the inner wall of the tube body 1 in the axial direction of the tube body 1. The setting of the sealing ring 4 is used to ensure that the reaction liquid is discharged through the second flow hole 30, ensure the sealing between the second baffle plate 32 and the inner wall of the tube body 1, and increase the pressure applied to the reactants inside the tube body 1.

[0043] In some embodiments, a partition plate 5 is sandwiched between the first folding willow component 2 and the inner wall of the liquid inlet end of the pipe 1 , and a liquid inlet through hole 51 coaxially arranged with the first flow hole 21 is opened on the partition plate 5 .

[0044] The working principle of the utility model is:

[0045] The mixed solution is introduced from the liquid inlet 11 , and after entering the liquid inlet channel 14 , the solution flows through a plurality of first baffles 23 and a plurality of second baffles 32 , is pressurized through the liquid outlet channel 15 , and is discharged from the liquid outlet 12 .

[0046] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
