AI Technical Summary

Technical Problem

In the existing technology, the wastewater generated during washing and dehydration in the production process of ternary precursors cannot be effectively recycled, resulting in waste of ternary precursors and high production costs.

Method used

Design a ternary precursor production device with washing, dehydration and recycling functions, including a production system, a washing water recycling system and a dehydration recycling system. The washing water and dehydration water are completely recycled and reused through filtration and storage tank connection, reducing the amount of production wastewater and pure water used.

Benefits of technology

It achieves complete recycling of washing and dehydration water, reduces production costs, improves production efficiency, saves energy through heat recovery, and reduces wastewater treatment costs.
