AI Technical Summary

Technical Problem

Existing reactors suffer from problems such as uneven stirring, inability to scale up, low stirring efficiency, difficulty in accurately controlling temperature and pH, high operating noise, and oil leakage, which affect material performance, especially in the synthesis of lithium battery precursors.

Method used

The jet reactor consists of a cylindrical reactor shell, a jet mixer, and a central reflux device. Through the synergistic effect of the multi-layer jet mixer and the central reflux device, the velocity gradient generated by mechanical stirring is eliminated, achieving uniform mixing throughout the entire reactor. Precise temperature control is achieved through a jacket and coil structure.

Benefits of technology

It improves reaction uniformity and control precision, reduces operating noise, supports large-scale and mass production of reactors, and enhances production efficiency and product quality.
