AI Technical Summary

Technical Problem

Traditional hydrocyclones lack flow guidance design in their dust and sand inlet structure, resulting in turbulent flow field, reduced separation efficiency, easy accumulation of solid particles, rapid wear of the inner wall, and severe backflow of fine particles, making it difficult to meet the requirements for high-purity separation.

Method used

The dust and sand pipe is designed with tapered sections that decrease from the outside to the inside, and multiple spiral guide plates are set around the inner wall. The spiral guide plates are opened with strip-shaped slots to form a stable spiral flow field and optimize the flow field distribution.

Benefits of technology

It significantly improves solid-liquid separation efficiency, extends equipment life, increases separation accuracy, reduces equipment vibration and noise, and enhances operational stability.
