Tubular reactor

The utility model discloses a tubular reactor, which belongs to the technical field of chemical reaction equipment and comprises a stirring shaft provided with a plurality of fins; the reaction tube is arranged on the stirring shaft in a sleeving manner, and a reaction cavity is formed between the reaction tube and the stirring shaft; a plurality of baffles are arranged on the inner wall surface of the reaction tube; a feed port is formed in one end of the reaction tube, a discharge port is formed in the other end of the reaction tube, and the feed port and the discharge port are both communicated with the reaction cavity; in the stirring and mixing process of materials, the fins interact with the baffle on the inner wall of the reaction tube along with the rotation of the stirring shaft, so that the shearing force on the materials can be greatly increased, and two-phase or multi-phase materials with different densities can be mixed more uniformly; the baffle plate is in the triangular prism state, so that wh
