Description

Technical Field

[0001] The invention relates to the field of electrolysis, and in particular to a method, a device, an electronic device and a medium for correcting anode voltage drop in an aluminum electrolysis cell. Background Art

[0002] In the electrolytic aluminum industry, the Hall-Heroult electrolysis process is widely used in aluminum production. The electrolysis method of the Hall-Heroult electrolysis process is to put a mixed solution of cryolite, alumina and aluminum fluoride into the electrolytic cell. After the DC voltage is applied to the electrolytic cell, the positively charged aluminum ions will gather near the cathode of the electrolytic cell, and the aluminum ions will gain electrons to generate elemental aluminum, while the oxygen ions will lose electrons near the anode of the electrolytic cell to generate oxygen atoms. The anode of the electrolytic cell is composed of a number of anode aluminum guide rods, each of which is connected to a number of steel claws, and each of which is connected to a number of anode carbon block groups. The anode carbon block group is regarded as the "heart" of the electrolytic cell and plays a vital role in the Hall-Heroult electrolysis process.

[0003] According to electrolysis theory, the decomposition voltage of alumina accounts for about 70% of the total voltage of the electrolytic cell, and the remaining voltage drop is caused by the resistance of the power supply circuit in the electrolytic cell, of which the voltage drop of the anode carbon block group accounts for about 7% to 11% of the total voltage drop of the power supply circuit. Therefore, studying and improving the conductive properties of the electrolytic cell anode, especially analyzing the voltage drop of each part of the anode carbon block group, is the key to reducing the total voltage of the electrolytic cell.

[0004] Among them, the voltage drop (voltage) of the phosphorus pig iron in the anode carbon block group can directly reflect the conductive properties of the anode carbon block group and the conductive condition of the phosphorus pig iron, that is, the resistance of the phosphorus pig iron. However, the current voltage drop measurement technology of the phosphorus pig iron can only obtain the raw data of the phosphorus pig iron voltage. Moreover, due to the influence of the anode current distribution of the electrolytic cell, the accuracy of the raw data of the phosphorus pig iron voltage is low, and it is unable to accurately reflect the conductive properties of the anode carbon block group and the resistance of the phosphorus pig iron. Summary of the invention

[0050] The core of the present invention is to provide a method, device, electronic equipment and medium for correcting the anode voltage drop of an aluminum electrolytic cell, because the ratio of the voltage drop of a single anode aluminum guide rod to the average voltage drop of all anode aluminum guide rods is related to the ratio of the anode current of a single anode aluminum guide rod to the average anode current of all anode aluminum guide rods, and the ratio of the anode current of a single anode aluminum guide rod to the average anode current of all anode aluminum guide rods can characterize the anode current distribution of a single anode aluminum guide rod, and because the anode current distribution of the anode aluminum guide rod affects the accuracy of the voltage drop of phosphorus pig iron, the present application corrects the voltage of phosphorus pig iron by the ratio of the anode current of each anode aluminum guide rod to the average anode current of all anode aluminum guide rods, thereby eliminating the influence of the anode current distribution on the determination of the phosphorus pig iron voltage.

[0051] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] Please refer to Figure 1 , Figure 1 The present invention provides a process flow chart of a method for correcting anode voltage drop in an aluminum electrolytic cell. The method for correcting anode voltage drop in an aluminum electrolytic cell comprises:

[0053] S11: obtaining current voltage drops of a plurality of anode aluminum guide rods of the current aluminum electrolytic cell, and determining a current average voltage drop of all anode aluminum guide rods according to each current voltage drop;

[0054] S12: obtaining the current voltage of several groups of phosphorus pig iron corresponding to each anode aluminum guide rod;

[0055] S13: determining the ratio of the anode current of each anode aluminum guide rod to the average anode current of all anode aluminum guide rods according to the ratio of each current voltage drop to the current average voltage drop;

[0056] S14: Correcting each current voltage according to the ratio of the anode current of each anode aluminum guide rod to the average anode current of all anode aluminum guide rods to obtain a corrected voltage of each phosphorus pig iron.

[0057] In the present invention, it is considered that the current voltage drop measurement technology of phosphorus pig iron in the prior art can only obtain the original data of phosphorus pig iron voltage, and because it is affected by the anode current distribution of the electrolytic cell, the accuracy of the original data of the phosphorus pig iron voltage is low, and it is unable to accurately reflect the conductivity of the anode carbon block group and the resistance of the phosphorus pig iron. Because the anode current distribution of the electrolytic cell can be characterized by the ratio of the anode current of a single anode aluminum guide rod to the average anode current of all anode aluminum guide rods, this scheme needs to first obtain the current voltage drops of several anode aluminum guide rods of the current aluminum electrolytic cell, and determine the current average voltage drop of all anode aluminum guide rods according to each current voltage drop, and then determine the anode current of each anode aluminum guide rod and the average anode current of all anode aluminum guide rods according to the ratio of each current voltage drop to the current average voltage drop. The ratio of the average anode current of the anode aluminum guide rod is used, that is, because the resistance of a single aluminum guide rod is approximately equal when only the anode current distribution of the electrolytic cell is considered, the ratio of the voltage drop of a single aluminum guide rod to the average voltage drop of all anode aluminum guide rods can characterize the ratio of the anode current of a single anode aluminum guide rod to the average anode current of all anode aluminum guide rods. Finally, the current voltage can be corrected by the ratio of the anode current of a single anode aluminum guide rod to the average anode current of all anode aluminum guide rods, and the corrected voltage of each phosphorus pig iron can be accurately obtained. The present application corrects the voltage of the phosphorus pig iron by the ratio of the anode current of each anode aluminum guide rod to the average anode current of all anode aluminum guide rods, and can eliminate the influence of the anode current distribution on the determination of the phosphorus pig iron voltage.

[0058] It should be noted that the pressure drop of phosphorus pig iron The premise for directly reflecting the resistance of phosphorus pig iron is that the current flowing through different phosphorus pig irons is equal. Due to the fluctuations in the anode position, the conditions of each slot, and the temperature field, the conductivity of each anode is different. Correcting the phosphorus pig iron voltage based on the idea of ​​unified current can better reflect the resistance of phosphorus pig iron.

[0059] The present embodiment provides a method for correcting the anode voltage drop of an aluminum electrolytic cell, because the ratio of the voltage drop of a single anode aluminum guide rod to the average voltage drop of all anode aluminum guide rods is related to the ratio of the anode current of a single anode aluminum guide rod to the average anode current of all anode aluminum guide rods, and the ratio of the anode current of a single anode aluminum guide rod to the average anode current of all anode aluminum guide rods can characterize the anode current distribution of a single anode aluminum guide rod, and because the anode current distribution of the anode aluminum guide rods affects the accuracy of the voltage drop of phosphorus pig iron, the present application corrects the voltage of phosphorus pig iron by the ratio of the anode current of each anode aluminum guide rod to the average anode current of all anode aluminum guide rods, thereby eliminating the influence of the anode current distribution on the determination of the phosphorus pig iron voltage.

[0060] Based on the above embodiments:

[0061] As an optional embodiment, each current voltage is corrected according to the ratio of the anode current of each anode aluminum guide rod to the anode average current of all anode aluminum guide rods to obtain the corrected voltage of each phosphorus pig iron, including:

[0062] Obtain the number of first claws of the steel claws connected to each anodized aluminum guide rod;

[0063] Determine the current of each phosphorus pig iron according to the ratio of the anode current of each anode aluminum guide rod to the average anode current of all anode aluminum guide rods and the number of each first claw;

[0064] Determine the current resistance of each phosphorus pig iron according to each current voltage, the current current of each phosphorus pig iron, the anode current of each anode aluminum guide rod, the number of first claws, the average anode current of all anode aluminum guide rods, the ratio of the anode current of each anode aluminum guide rod to the average anode current of all anode aluminum guide rods, and the resistance calculation formula;

[0065] Determining a correction voltage for each phosphorus pig iron based on each current resistance;

[0066] The resistance calculation formula is: ; is the current resistance, is the current voltage of the i-th phosphorus pig iron, is the anode current of the i-th anode aluminum guide rod, is the number of the first claw, is the current of the ith phosphorus pig iron, is the average anode current of each anode aluminum guide rod, is the current average voltage drop, is the current voltage drop of the i-th anode aluminum guide rod, Characterizes the correction voltage of the i-th phosphorus pig iron, It is the reciprocal of the ratio of the anode current of each anode aluminum guide rod to the average anode current of all anode aluminum guide rods.

[0067] In the present invention, the actual process of correcting each current voltage according to the ratio of the anode current of each anode aluminum guide rod to the anode average current of all anode aluminum guide rods is as follows: first, the number of first claws of the steel claws connected to each anode aluminum guide rod is obtained, and then the ratio of the anode current of each anode aluminum guide rod to the anode average current of all anode aluminum guide rods, the current voltage of phosphorus pig iron and other parameters are substituted into the phosphorus pig iron resistance determination formula, and the weighted phosphorus pig iron voltage, that is, the corrected voltage of phosphorus pig iron, can be calculated. , ensuring the integrity of the phosphorus pig iron voltage correction process.

[0068] It should be noted that when the effect of temperature on the voltage drop of the anode guide rod is not considered, the parameter used to evaluate the anode conductivity is the anode current distribution , The larger the anode is, the better the conductivity is and the larger the current is. ; The current of phosphorus pig iron is , is the number of claws of the steel claw, is the resistance of the anodized aluminum rod, then the resistance of phosphorus cast iron , for all anodes in the same series of electrolytic cells in the same workshop are the same value, That is, it is the weighted voltage drop of phosphorus pig iron based on uniform current, and this phosphorus pig iron voltage drop can avoid the distortion of phosphorus pig iron resistance reflection caused by uneven current distribution.

[0069] As an optional embodiment, after obtaining the current voltages of several groups of phosphorus pig iron corresponding to each anode aluminum guide rod, the method further includes:

[0070] Obtain the current temperature of each anodized aluminum guide rod, and determine the current temperature average of all anodized aluminum guide rods according to each current temperature;

[0071] Accordingly, each current voltage is corrected according to the ratio of the anode current of each anode aluminum guide rod to the average anode current of all anode aluminum guide rods to obtain the corrected voltage of each phosphorus pig iron, including:

[0072] Determine the preset resistance temperature correction factor of the anodized aluminum guide rod;

[0073] The correction voltage of each phosphorus pig iron is determined according to each current temperature, the current temperature average value, the preset resistance temperature correction coefficient, the ratio of the anode current of each anode aluminum guide rod to the anode average current of all anode aluminum guide rods, and each current voltage.

[0074] In the present invention, since the temperature field of the electrolytic cell fluctuates, after considering the influence of the anode current distribution of the electrolytic cell on the voltage drop of the phosphorus pig iron, it is also necessary to consider the influence of the temperature change of the anode aluminum guide rod on the voltage drop of the phosphorus pig iron. Therefore, this scheme will also obtain the current temperature of each anode aluminum guide rod, and determine the current temperature average value of all anode aluminum guide rods according to each current temperature, and determine the preset resistance temperature correction coefficient of the anode aluminum guide rod. Finally, the corrected voltage of each phosphorus pig iron is determined according to each current temperature, the current temperature average value, the preset resistance temperature correction coefficient, the ratio of the anode current of each anode aluminum guide rod to the anode average current of all anode aluminum guide rods, and each current voltage. That is, this scheme not only considers the influence of the anode current distribution of the electrolytic cell on the voltage drop of the phosphorus pig iron, but also considers the influence of the temperature change of the anode aluminum guide rod on the voltage drop of the phosphorus pig iron, so that the actual correction process of the phosphorus pig iron voltage is more accurate, thereby improving the accuracy and reliability of the scheme.

[0075] As an optional embodiment, the correction voltage of each phosphorus pig iron is determined according to each current temperature, the current temperature average value, the preset resistance temperature correction coefficient, the ratio of the anode current of each anode aluminum guide rod to the anode average current of all anode aluminum guide rods, and each current voltage, including:

[0076] Determine the correction voltage of each phosphorus pig iron according to each current temperature, the current temperature average value, the preset resistance temperature correction coefficient, the ratio of the anode current of each anode aluminum guide rod to the anode average current of all anode aluminum guide rods, each current voltage and the phosphorus pig iron voltage correction formula;

[0077] Among them, the voltage correction formula of phosphorus pig iron is: ; is the preset resistance temperature correction coefficient, is the current temperature, is the current average temperature, Characterizes the correction voltage of the i-th phosphorus pig iron.

[0078] In the present invention, after simultaneously considering the influence of the anode current distribution of the electrolytic cell on the voltage drop of the phosphorus pig iron and the influence of the temperature change of the anode aluminum guide rod on the voltage drop of the phosphorus pig iron, the actual value of the resistance of the anode aluminum guide rod is related to the preset resistance temperature correction coefficient and the temperature change, and there is a corresponding formula. Therefore, after referring to the resistance of the anode aluminum guide rod, the current temperature, the current temperature average value, the preset resistance temperature correction coefficient, the ratio of the anode current of each anode aluminum guide rod to the anode average current of all anode aluminum guide rods, and the current voltage can be directly substituted into the phosphorus pig iron voltage correction formula to accurately determine the corrected voltage of each phosphorus pig iron.

[0079] It should be noted that due to the fluctuation of the temperature field of the electrolytic cell, the anode current distribution It is also necessary to consider the resistance temperature correction to obtain the corrected current, that is, , and the resistance correction formula of the anodized aluminum guide rod is: ,in, is the actual resistance of the anodized aluminum guide rod, is the resistance of the anode aluminum guide rod at 0°C, so the phosphorus pig iron correction voltage obtained by weighting the voltage based on the correction current is The phosphorus pig iron correction voltage can better reflect the resistance of phosphorus pig iron by taking into account the cell condition, anode conductivity and temperature field fluctuation.

[0080] As an optional embodiment, after correcting each current voltage according to the ratio of the anode current of each anode aluminum guide rod to the anode average current of all anode aluminum guide rods to obtain the corrected voltage of each phosphorus pig iron, it also includes:

[0081] Obtain the number of first anodes of the current aluminum electrolysis cell and the number of second anodes of the aluminum electrolysis cell to be compared;

[0082] Obtain the number of second claws of the steel claws in the current aluminum electrolysis cell and the number of third claws of the steel claws in the aluminum electrolysis cell to be compared;

[0083] The corrected voltage of the phosphorus pig iron in the aluminum electrolytic cell to be compared is determined according to the first number of anodes, the second number of anodes, the second number of claws, the third number of claws and the corrected voltage of each phosphorus pig iron in the current aluminum electrolytic cell.

[0084] In the present invention, considering that the voltage drop measurement technology of phosphorus pig iron in the prior art can only obtain the original data of the voltage drop of phosphorus pig iron, it is impossible to directly determine the corrected voltage of phosphorus pig iron to be compared with different series of electrolytic cells and different series of steel claw numbers according to the current corrected voltage of phosphorus pig iron, that is, it is impossible to compare the voltage drop of phosphorus pig iron with different series of electrolytic cells and different steel claw structures, resulting in the actual phosphorus pig iron voltage measurement process taking too long, seriously affecting the efficiency, and once the measurement process is too long, it will also cause the voltage drop of phosphorus pig iron to change, affecting the actual measurement result. Therefore, this scheme obtains the first anode number of the current aluminum electrolytic cell and the second anode number of the aluminum electrolytic cell to be compared, and obtains the second claw head number of the steel claw in the current aluminum electrolytic cell and the third claw head number of the steel claw in the aluminum electrolytic cell to be compared, and finally determines the corrected voltage of the phosphorus pig iron in the aluminum electrolytic cell to be compared according to the first anode number, the second anode number, the second claw head number, the third claw head number and the corrected voltage of each phosphorus pig iron in the current aluminum electrolytic cell. That is, after determining the corrected voltage of the phosphorus pig iron in the current electrolytic cell, this scheme can also quickly determine the corrected voltage of the phosphorus pig iron in the aluminum electrolytic cell to be compared, which greatly improves the efficiency of the phosphorus pig iron voltage drop measurement.

[0085] As an optional embodiment, determining the correction voltage of the phosphorus pig iron in the aluminum electrolytic cell to be compared according to the first anode number, the second anode number, the second claw number, the third claw number and the correction voltage of each phosphorus pig iron in the current aluminum electrolytic cell includes:

[0086] Determine a first series of currents of the current aluminum electrolysis cell and a second series of currents of the aluminum electrolysis cell to be compared;

[0087] Determine the current coefficient according to the first series current, the second series current, the first anode number, the second anode number, the second prong number, and the third prong number;

[0088] The correction voltage of the phosphorus pig iron in the aluminum electrolytic cell to be compared is determined based on the product of the current coefficient and the correction voltage of each phosphorus pig iron in the current aluminum electrolytic cell.

[0089] In the present invention, the specific process of determining the corrected voltage of the phosphorus pig iron in the aluminum electrolytic cell to be compared is: first determine the first series current of the current aluminum electrolytic cell and the second series current of the aluminum electrolytic cell to be compared, and determine the current coefficient based on the determined first series current, second series current, first anode number, second anode number, second claw number, and third claw number; finally, the corrected voltage of the phosphorus pig iron in the aluminum electrolytic cell to be compared can be determined based on the product of the current coefficient and the corrected voltage of each phosphorus pig iron in the current aluminum electrolytic cell, thereby ensuring the integrity of the process of determining the corrected voltage of the phosphorus pig iron in the aluminum electrolytic cell to be compared.

[0090] As an optional embodiment, the current coefficient is determined according to the first series current, the second series current, the first anode number, the second anode number, the second claw number, and the third claw number, including:

[0091] Determine the current coefficient according to the first series current, the second series current, the number of first anodes, the number of second anodes, the number of second prongs, the number of third prongs and the current coefficient determination formula;

[0092] Among them, the current coefficient determination formula is: ; is the current coefficient, is the first series current, is the second series current, is the first anode number, is the second anode number, is the number of the second claws, The number of the third claw.

[0093] In the present invention, considering that the current coefficient is related to the series current of the current aluminum electrolytic cell and the aluminum electrolytic cell to be compared and the number of claws of the steel claw, and there is a determination formula for the current coefficient, it is only necessary to substitute the determined first series current, second series current, first number of anodes, second number of anodes, second number of claws, and third number of claws into the current coefficient determination formula to accurately determine the current coefficient, and then the subsequent process of determining the correction voltage of the phosphorus pig iron in the aluminum electrolytic cell to be compared can be completed.

[0094] It should be noted that the phosphorus pig iron correction voltage It can be directly used for the comparison of phosphorus pig iron voltage drop in the same workshop of a single series of electrolytic cells. When conducting phosphorus pig iron tests, this voltage drop directly reflects the resistance of phosphorus pig iron. Convert other series of electrolytic cells to correct voltage for phosphorus pig iron ,in , is the series current, , is the number of anodes in the electrolytic cell, , is the number of steel claws, , , For other series of electrolytic cell parameters, , ,in is the average current of the current series of electrolytic cell guide rods, It is the average current of the guide rods of other series of electrolytic cells.

[0095] The basic idea of ​​introducing the current coefficient is to unify the current and correct the voltage in the phosphorus pig iron. The uniform phosphorus pig iron current is , the comparison of the phosphorus pig iron voltage across series of electrolytic cells requires the unification of the phosphorus pig iron current. Now the phosphorus pig iron current of other series of electrolytic cells is unified to the phosphorus pig iron current of the current series of electrolytic cells, then , , Therefore, the phosphorus pig iron current of other series of electrolytic cells is multiplied by the current coefficient It is equal to the current series electrolytic cell phosphorus pig iron current, phosphorus pig iron resistance , uniform phosphorus pig iron current requires , so the phosphorus iron voltage is multiplied by the current coefficient The phosphorus pig iron current can be unified to achieve the phosphorus pig iron voltage comparison across the series of electrolytic cells, that is, and comparison.
