[0019] In order to make the utility model's purpose, technical scheme and advantage more clearly, the following is combined with the drawing and example, and the utility model is further detailedly explained. It should be understood that the specific example described here is only used to explain the utility model, and is not used to limit the utility model.
[0020] As shown in the drawing, Figure 1 A mixed uniform microreactor, comprising: inlet 1, reaction tube 2, connecting pipe 3, material outlet 4.
[0021] As shown in the drawing, Figure 1As shown, the reaction generating tube 2 is fed into the first blocking structure 21 from the top. After being blocked by the first diversion structure 21, part of the reaction liquid flows out from the middle to the first slow-flow structure 22, while the other part continues to flow downward along the wall. The reaction liquid in the middle is divided into two branches, left and right, by the first slow-flow structure 22. The reaction liquid on the side is divided into two directions by the second diversion structure 23, with one part converging towards the middle and the other part continuing to flow downward along the wall. The reaction liquid on the left is divided into two streams, left and right, by the second slow-flow structure 24, one of which mixes with the reaction liquid on the right that has passed through the second diversion structure 23. Finally, the fully mixed liquid is divided by the diversion block 25.
[0022] The first flow-slowing structure 22 and the second flow-slowing structure 24 are olive-shaped, and the second flow-diverting structure 23 is arc-shaped.
[0023] like Figure 2 As shown, there are 5 reaction generating tubes 2, with the bottom being the feed inlet 1. The reaction liquid enters from the material inlet 1 and then enters the connecting tube 3 through the 5 reaction generating tubes 2. The connecting tube 3 is equipped with baffles to block the reaction liquid and prevent the reaction liquid from flowing too fast.
[0024] like Figure 3 As shown, the adjacent reaction generating tubes 2 are connected by a connecting tube 3, and the two horizontally adjacent reaction generating tubes 2 are arranged in opposite directions, forming an S-shaped flow; the lower left is the inlet 1, and the lower right is the material outlet 4;
[0025] Preferably, the reaction liquid undergoes multiple splits and collisions inside as it is struck by multiple obstructions and mixed with reaction liquids flowing in different directions, resulting in a more uniform reaction mixture.
[0026] Working principle of this utility model:
[0027] First, after the reaction liquid enters the reaction generating tube 2 through the feed port 1, the reaction liquid is blocked by the first diversion structure 21 when it flows through the first diversion structure 21, so that part of the reaction liquid flows out from the middle to the first slow flow structure 22, and the other part continues to flow down along the wall.
[0028] The central reaction liquid is divided into two branches, left and right, by the first slow-flow structure 22. The side reaction liquid is divided into two directions by the second diversion structure 23. One part converges towards the center, and the other part continues to flow downward along the wall.
[0029] The reaction liquid on the left is divided into two streams via the second slow-flow structure 24, one of which mixes with the reaction liquid on the right via the second flow-splitting structure 23; the fully mixed liquid is then split by the flow-splitting block 25 into the connecting pipe 3, and the reaction liquid is blocked by the connecting pipe blocking structure 31 to prevent the flow from being too fast, and then enters another row of oppositely arranged reaction pipes 2, and finally the fully mixed reaction liquid flows out of the material outlet 4.
