AI Technical Summary

⚠Technical Problem

Traditional methods make it difficult to evenly add lime powder to the surface of anhydrous hydrogen fluoride mixed solution, resulting in local concentrations that are too high or too low, affecting the anion removal effect and reaction stability.

⚗Method used

Design a feeding device that includes a feeding tray and a feeding control component. The addition of lime powder is precisely controlled by a rotating plate and a sealing component, and a stirring component is used to ensure uniform mixing and avoid uneven concentration in some areas.

🎯Benefits of technology

The method achieves uniform addition of lime powder in anhydrous hydrogen fluoride mixed solution, which improves anion removal efficiency and reaction stability, shortens the production cycle, and reduces production costs.
