AI Technical Summary

Technical Problem

Traditional lithium aluminum hydrotalcite adsorbents are prone to forming large-sized aggregates during preparation due to electrostatic interactions or hydrodynamic effects between particles. This results in poor product uniformity, decreased adsorption performance, insufficient real-time monitoring and positioning capabilities, low dispersion efficiency, low automation, high misjudgment rate in existing systems, and delayed control response.

Method used

A preparation system based on intelligent sensing is adopted, which combines a laser measurement unit, a pneumatic drive unit and multimodal data fusion technology to monitor and locate the aggregates in real time. The aggregates are then dispersed through pneumatic drive and multi-level collaborative dispersion units, achieving automatic detection, positioning and processing.

Benefits of technology

The adsorption performance of lithium aluminum hydrotalcite adsorbent has been improved, enhancing the efficiency of lithium batteries and exhaust gas treatment in new energy vehicles, reducing energy consumption, and realizing fully automated control of the entire process.
