建立一种研究气泡对槽电压波动影响的方法,该方法将整个电解槽等效为一个电阻电路,并利用Matlab/Simulink仿真软件建立等效电路的仿真模型进行动态仿真研究,从而获得不同气泡状态下槽电压和阳极电流的时间序列数据,利用频谱和统计分析方法对这些数据进行分析。结果显示,较高的气泡释放频率对槽电压波动的影响更大,当一组阳极表面气泡覆盖率超过80%时,槽电压可能超出正常的波动范围。仿真结果证实了在实际生产中计算机监测到的阳极效应主要是全槽的阳极效应。
A method to study the effect of bubble on the voltage fluctuation in tank is established. The method equals the whole cell as a resistance circuit and uses Matlab / Simulink simulation software to establish the simulation model of equivalent circuit for dynamic simulation to obtain different bubble states Time-series data of the cell voltage and the anode current, and analyzed by spectrum and statistical analysis methods. The results show that the higher bubble release frequency has greater influence on the tank voltage fluctuation. When the bubble coverage of one anode surface exceeds 80%, the tank voltage may exceed the normal fluctuation range. The simulation results confirm that the anodic effect monitored by the computer in actual production is mainly the anode effect of the full tank.
