AI Technical Summary
Existing technologies make it difficult to achieve continuous production of phosphorus pentoxide and anhydrous hydrogen fluoride, resulting in high cost and low efficiency in the preparation of phosphorus oxyfluoride. Furthermore, fluidized bed towers are prone to phosphorus pentoxide agglomeration, which affects normal operation.
A reaction device for the preparation of phosphorus oxyfluoride is designed, which adopts a gas-solid distribution mechanism, a guiding mechanism, and a heat exchange mechanism. A dynamic airflow field is formed by the bidirectional rotation of the airflow distribution component and the rotation of the guide plate assembly, which breaks up the agglomeration of solid particles, improves the gas-solid contact efficiency, and achieves full heat exchange and separation through the spiral rising airflow.
The homogeneous reaction of phosphorus pentoxide and anhydrous hydrogen fluoride was achieved, reducing production costs, improving reaction efficiency, avoiding solid adhesion and temperature instability problems, and ensuring the efficient preparation of phosphorus trifluoride.
