Online detection method of aluminium electrolyzer tank condition based on area current

At present, the aluminium electrolytic cell is developing in the direction of large-scale, but it still adopts the past ‘overunder’ discharging method for the control of alumina concentration, which has low current efficiency and frequent occurrence of anode effect. The development of fiber optic measurement technology provides new possibilities for the measurement of anode current in electrolytic tanks. Based on fiber optic current measurement technology and modern detection technology, this paper develops a real-time monitoring system for aluminium electrolytic tanks based on regional current, realizes accurate online measurement of regional current and tank voltage in aluminium electrolytic tanks and uploads data to the cloud, realizes fine feedback of alumina concentration, and provides data support and technical guarantee for the independent discharging of aluminium electrolytic tanks in different regions.
