Triple Intercell Bar for Electrometallur

PV energy prices are declining rapidly, prompting the need for modified operational practices to lower carbon footprints and improve the efficiency of electrowinning operations. This work presents an innovative triple intercell bar designed for enhanced modulation of electrode current distribution, facilitating increased daytime current usage and reduced nighttime consumption. Operating in current-source mode, this proprietary system is designed with a dogbone-type capping board, enhancing safety by preventing short circuits and allowing for easy repairs. The configuration of twin auxiliary connectors ensures robust current paths, thereby minimizing the risk of contact arcing, while the conductive elements are strategically positioned to maximize ventilation and reduce operating temperatures. A critical advantage of this design is its ability to maintain a balanced cathode current, crucial for effective polarity modulation and optimization of photovoltaic energy usage. The findings are supported by a 3D finite element method model predicting electric and thermal performance across various industrial scenarios, alongside preliminary results from trials conducted in an electrowinning facility utilizing industrial prototypes.
