AI Technical Summary
Existing real-time measurement devices for current efficiency in aluminum electrolysis cells have shortcomings in achieving uniformity of data acquisition and measurement over a large area at multiple points, resulting in poor uniformity of the acquired data.
A distributed acquisition component, including a central tube and multiple dispersed tubes, is evenly distributed at the sampling port of the aluminum electrolysis cell. Combined with a sealing component, it ensures a sealing effect, achieving uniform gas acquisition and sealing. Current efficiency is measured in real time using oxygen, carbon monoxide, and carbon dioxide sensors.
It achieves broader uniform acquisition and better measurement uniformity, while improving the sealing effect, ensuring the real-time accuracy and stability of current efficiency measurement.
