Moreover, the number of floors and the number of units can be designed and constructed according to the actual situation. It can be used as a single-layer reactor or a multi-layer reactor, that is, one reactor can realize the functions of multiple reactors, shorten the reaction time, reduce backmixing, and has higher efficiency, which can bring higher economic benefits;

The tower structure design occupies a small area and improves the volume utilization rate. The number of layers and the number of uses can be designed and constructed according to actual conditions. It can be used as a single-layer reactor or a multi-layer reactor, that is, one reactor can realize the functions of multiple reactors, shorten the reaction time, reduce back mixing, and be more efficient, which can bring higher economic benefits. During the production process, the raw liquid enters from the feed port of the lowest tower section 2. When the liquid is filled The liquid in the current tower section 2 enters the next tower section 2 through the liquid rising hole 5 until the liquid rises to the highest tower section 2 and is discharged from the discharge port. The feed port of the middle tower section 2 can be provided with a sampling port or a plug for sealing. The present application ensures that the solution in the tower section 2 is heated evenly when the heat exchange jacket 3 is used by providing a mixing component 10. The tower section 2 located at the highest level is fixed to the mounting plate 1001 through the reserved mounting screw hole 9.
