Abstract

The invention relates to a method for forecasting anode effects by isometric voltage drop of anode rods. The method includes that anode rod isometric voltage drop signal sensors are respectively mounted on different anode rods of a prebaked anode electrolytic cell and used for transmitting acquired anode rod isometric voltage drop signals to a front-end data analyzer; and the front-end data analyzer is used for analyzing anode rod isometric voltage drop data, forecasting anodes about to have the anode effects, and then sending the forecasting results to an electrolytic cell controller. The method has the advantages that conditions of the anode effect of the single anode of the electrolytic cell can be forecasted intensively, abnormal anodes can be monitored effectively, refined operation of the electrolytic cell is realized, running of the electrolytic cell is stabilized, and effects of saving energy, reducing consumption and improving current efficiency are realized.

Description

Technical field [0001] The invention relates to a method for predicting the anode effect by using the equidistant pressure drop of the anode guide rod, in particular to predicting the individual anodes of the prebaked anode aluminum electrolytic cell that are about to have the anode effect by using the equidistant pressure drop data of the anode guide rod of the electrolytic cell. Background technique [0002] The traditional method of predicting the anode effect of the electrolytic cell is to analyze and process the overall voltage signal of the electrolytic cell, and predict the anode effect of the electrolytic cell according to the signal size of the overall cell voltage. However, in actual production, the anode effect often occurs on individual anodes. In recent years, as the size of the electrolytic cell continues to increase, the shortcomings of traditional anode effect prediction methods have been exposed. The original method of predicting the anode effect through the ove...

However, in actual production, the anode effect often occurs on individual anodes first. In recent years, with the continuous increase in the size of the electrolytic cell, the shortcomings of the traditional anode effect prediction method are constantly exposed

The original method of predicting the anode effect through the overall tank voltage can only determine that the anode effect is about to occur in the entire tank, and cannot determine the specific area where the anode effect is about to occur. Carry out large-scale feeding, which will change the concentration of alumina in the electrolyte, making it uneven in spatial distribution and increasing the consumption of alumina

This traditional anode effect prediction method, which does not consider the differences in specific anodes, can no longer meet the requirements for refined operation of new electrolytic cells, nor does it meet the current society's goal of reducing energy consumption in the aluminum electrolysis process.
