[0002] Domestic aluminum electrolysis companies are located in different regions across the country. China's distinct four seasons, coupled with regional temperature differences, result in corresponding changes in the energy balance of each aluminum electrolysis cell throughout the year. Most aluminum electrolysis companies generally use current or power control, lacking an effective energy balance adjustment method for the entire aluminum electrolysis system. Some aluminum electrolysis companies only adjust the current intensity accordingly in summer and winter, failing to develop a more systematic energy balance adjustment method. Currently, most aluminum electrolysis companies mostly use energy balance adjustment based on individual electrolysis cells, which is relatively inconsistent and slow to achieve results.

[0030] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only 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 making creative efforts shall fall within the scope of protection of the present invention.

[0031] The following will describe some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0032] According to the first aspect of the embodiment of the present application, a method for regulating energy balance in aluminum electrolysis is provided. Figure 1 shown.

[0033] See also Figure 1 , shows a flow chart of an aluminum electrolysis energy balance control method according to an embodiment of the present application, specifically including S110 to S130.

[0034] S110, obtaining a first temperature difference between the current ambient temperature of the target electrolytic aluminum series and the set ambient temperature, and a second temperature difference between the current large busbar temperature and the set large busbar temperature.

[0035] In some embodiments, a busbar temperature and ambient temperature detection device may be installed at the busbar end of each electrolytic aluminum series, thereby enabling continuous detection of the busbar temperature and ambient temperature of the electrolytic aluminum series. For example, two temperature sensors may be installed at the busbar end of the electrolytic aluminum series, thereby enabling continuous detection of the busbar temperature and ambient temperature.

[0036] Regarding the set ambient temperature and the set large busbar temperature, in some embodiments, the set ambient temperature is the ambient temperature when the current intensity of the target electrolytic aluminum series was last adjusted; the set large busbar temperature is the large busbar temperature when the current intensity of the target electrolytic aluminum series was last adjusted.

[0037] For example, if the ambient temperature was 25°C and the busbar temperature was 39.9°C when the current intensity of the target electrolytic aluminum was adjusted last time, then the 25°C is the set ambient temperature and the 39.9°C is the set busbar temperature.

[0038] In some embodiments, the set ambient temperature and the set busbar temperature may be set in combination with the process characteristics of the target electrolytic aluminum series and the environmental conditions of the region where the target electrolytic aluminum is located. For example, the set ambient temperature may be set to 20° C. and the set busbar temperature may be set to 35° C.

[0039] It should be noted that, in this embodiment, the specific setting implementation methods for setting the ambient temperature and setting the large bus temperature are not limited in this application.

[0040] In this embodiment, it can be understood that the first temperature difference between the current ambient temperature of the target electrolytic aluminum series and the set ambient temperature is continuously monitored in real time, and the second temperature difference between the current large busbar temperature and the set large busbar temperature is continuously monitored in real time. The first temperature difference may be 0, a positive number, or a negative number, and the second temperature difference may be 0, a positive number, or a negative number.

[0041] Generally speaking, the ambient temperature and the busbar temperature show corresponding trends. For example, when the ambient temperature of the target electrolytic aluminum series increases, the corresponding busbar temperature will also increase.

[0042] For example, if the target electrolytic aluminum series has a set ambient temperature of 20°C and a set busbar temperature of 35°C, and after monitoring, the current ambient temperature is 30°C and the current busbar temperature is 19.1°C, then it can be calculated that the first temperature difference is -5°C (30°C - 35°C) and the second temperature difference is -0.9°C (19.1°C - 20°C).

[0043] Continue to see Figure 1 , S120, when the first temperature difference exceeds a first preset range and the second temperature difference exceeds a second preset range, determining a current intensity adjustment parameter and a fan opening adjustment parameter according to the first temperature difference and the second temperature difference.

[0044] In some embodiments, the first preset range is preferably set to [-8°C, +8°C], and the second preset range is preferably set to [-1°C, +1°C]. Therefore, the current intensity adjustment parameter and the fan opening adjustment parameter are determined only when the absolute value of the first temperature difference is greater than 8°C and the absolute value of the second temperature difference is greater than 1°C. Of course, corresponding first and second preset ranges can also be designed according to actual conditions, and this application does not impose specific limitations here.

[0045] In this embodiment, specific implementations of determining the current intensity adjustment parameter and the fan opening adjustment parameter based on the first temperature difference and the second temperature difference include at least the following two implementations:

[0046] The first implementation method:

[0047] You can follow the Figure 2 The steps shown are executed, including S121A to S122A.

[0048] S121A, obtains a reference current intensity and a reference fan opening.

[0049] In this embodiment, obtaining the reference current intensity and the reference fan opening degree may be performed according to the following steps S1211A to S1212A.

[0050] S1211A, obtaining at least one current intensity and at least one fan opening of the target electrolytic aluminum series within a set time.

[0051] Specifically, the set time may be the entire last year, or one or more years in the calendar year. This application does not make any specific limitation here.

[0052] It is understandable that the current intensity and fan opening of the target electrolytic cell series within the set time will change with the adjustment, so at least one current intensity and at least one fan opening can be obtained within the set time.

[0053] S1212A: Perform filtering and smoothing processing on the at least one current intensity and the at least one fan opening, respectively, to obtain a reference current intensity and a reference fan opening.

[0054] In some implementations, if only one current intensity and one fan opening are obtained, the current intensity and the fan opening are used as the reference current intensity and the reference fan opening.

[0055] In some embodiments, if multiple current intensities and multiple fan openings are obtained, weighted averages may be performed on the multiple current intensities and multiple fan openings, and the obtained values ​​may be used as reference current intensities and reference fan openings, respectively.

[0056] In some embodiments, if multiple current intensities and multiple fan openings are obtained, the medians of the multiple current intensities and the multiple fan openings can be taken as the reference current intensities and the reference fan opening, respectively.

[0057] In this embodiment, the specific method for obtaining the reference current intensity and the reference fan opening is not limited in this application.

[0058] Continue to see Figure 2, S122A, determine the current intensity adjustment parameter and the fan opening adjustment parameter according to the first temperature difference, the second temperature difference, the reference current intensity, and the reference fan opening.

[0059] The specific implementation of this embodiment can be as follows: Figure 3 The steps shown are executed, specifically including S1221A to S1224A.

[0060] S1221A: Obtain a first adjustment coefficient and a second adjustment coefficient.

[0061] S1222A: Determine a current intensity adjustment range based on the first adjustment coefficient and the reference current intensity, and determine a fan opening adjustment range based on the second adjustment coefficient and the reference fan opening.

[0062] In this embodiment, there are no specific limitations on the setting of the first adjustment coefficient, nor on the specific implementation of determining the current intensity adjustment amplitude based on the first adjustment coefficient and the reference current intensity. However, the present application shall adhere to the first principle that the current intensity adjustment amplitude determined by the first adjustment coefficient and the reference current intensity should be within 3% of the current intensity of the target electrolytic cell series. For example, if the current intensity is 400 kA, the current intensity adjustment amplitude obtained by the above two steps should be less than 12 kA.

[0063] A preferred implementation for setting the first adjustment coefficient and determining the current intensity adjustment amplitude based on the first adjustment coefficient and the reference current intensity is as follows:

[0064] The first adjustment coefficient is set to 0.6%, and the current intensity adjustment range is obtained by calculating the product of the first adjustment coefficient and the reference current intensity, ie, the current intensity adjustment range = 0.6% × reference current intensity.

[0065] In this embodiment, there is no specific limitation on the setting of the second adjustment coefficient, and the specific implementation method for determining the fan opening adjustment range based on the second adjustment coefficient and the reference fan opening is not specifically limited in this application. However, the second principle should be followed: the fan opening adjustment range determined by the second adjustment coefficient and the reference fan opening should be within 20% of the current fan opening of the target electrolytic cell series. For example, if the current fan opening is 100°, then the fan opening adjustment range obtained by the above two steps should be less than 20°.

[0066] A preferred implementation of the second adjustment coefficient and determining the fan opening adjustment range based on the second adjustment coefficient and the reference fan opening is as follows:

[0067] The second adjustment coefficient is set to 4%, and the fan opening adjustment range is obtained by calculating the product of the second adjustment coefficient and the reference fan opening, that is, the fan opening adjustment range = 4% × reference fan opening.

[0068] In this embodiment, the first principle setting is a limited setting based on the input energy requirements of the electrolytic cell series in four seasons. The second principle setting is a limited setting based on the output energy requirements of the electrolytic cell series in four seasons.

[0069] Continue to see Figure 3 , S1223A, if the first temperature difference and the second temperature difference are positive numbers, the difference between the reference current intensity and the current intensity adjustment amplitude is used as the current intensity adjustment parameter, and the sum of the reference fan opening and the fan opening adjustment amplitude is used as the fan opening adjustment parameter.

[0070] For example, assuming: first temperature difference = 9°C; second temperature difference = 1°C; base current = 500kA; current adjustment range = 3kA; base fan opening = 90°; fan opening adjustment range = 4°. Thus, the current adjustment parameter = 500kA - 3kA = 497kA; and the fan opening adjustment parameter = 90° + 4° = 94°.

[0071] Therefore, it can be understood that the current intensity of the target electrolytic cell needs to be lowered to reduce energy input, and the fan opening needs to be increased to increase series heat dissipation.

[0072] S1224A, if the first temperature difference and the second temperature difference are negative, the sum of the reference current intensity and the current intensity adjustment amplitude is used as the current intensity adjustment parameter, and the difference between the reference fan opening and the fan opening adjustment amplitude is used as the fan opening adjustment parameter.

[0073] For example, assuming: first temperature difference = -9°C; second temperature difference = -1°C; base current = 402kA; current adjustment range = 2.4kA; base fan opening = 86°; fan opening adjustment range = 3°. Therefore, it can be determined that the current adjustment parameter = 402kA + 2.4kA = 404.4kA; and the fan opening adjustment parameter = 86° - 3° = 83°.

[0074] Therefore, it can be understood that the current intensity of the target electrolytic cell series needs to be increased to increase energy input, and the fan opening needs to be lowered to reduce power consumption.

[0075] Continue to see Figure 1In S120, determining the current intensity adjustment parameter and the fan opening adjustment parameter according to the first temperature difference and the second temperature difference includes:

[0076] The second implementation method:

[0077] Specifically include Figure 4 As shown, it includes S121B to S124B.

[0078] S121B, obtaining a preset current intensity adjustment coefficient, a preset fan opening adjustment coefficient, the current current intensity of the target electrolytic cell series, and the current fan opening.

[0079] S122B, determining a current intensity adjustment range based on the preset current intensity adjustment coefficient and the current current intensity, and determining a fan opening adjustment range based on the preset fan opening adjustment coefficient and the current fan opening.

[0080] S123B, if the first temperature difference and the second temperature difference are positive numbers, the difference between the current current intensity and the current intensity adjustment range is used as the current intensity adjustment parameter, and the sum of the current fan opening and the fan opening adjustment range is used as the fan opening adjustment parameter.

[0081] S124B, if the first temperature difference and the second temperature difference are negative, the sum of the current current intensity and the current intensity adjustment amplitude is used as the current intensity adjustment parameter, and the difference between the current fan opening and the fan opening adjustment amplitude is used as the fan opening adjustment parameter.

[0082] In this embodiment, the present application does not specifically limit the specific implementation of the setting of the preset current intensity adjustment coefficient and the determination of the current intensity adjustment range based on the preset current intensity adjustment coefficient and the current current intensity, but the above-mentioned first principle should be followed. The present application does not specifically limit the specific implementation of the setting of the preset fan opening adjustment coefficient and the determination of the fan opening adjustment range based on the preset fan opening adjustment coefficient and the current fan opening, but the above-mentioned second principle should be followed.

[0083] Continue to see Figure 1 , S130, adjusting the current intensity and the fan opening of the target electrolytic aluminum series according to the current intensity adjustment parameter and the fan opening adjustment parameter.

[0084] In some embodiments, the current intensity of the target electrolytic cell series is adjusted by the power supply control system, and the fan opening angle of the target electrolytic cell series is adjusted by the high-pressure fan. For example, if the current intensity adjustment parameter is determined to be 497 kA and the fan opening adjustment parameter is determined to be 96°, the power supply control system adjusts the current intensity to 497 kA and the high-pressure fan adjusts the fan opening to 96°.

[0085] According to a second aspect of an embodiment of the present application, an aluminum electrolysis energy balance control system is provided.

[0086] See also Figure 5 , shows an architectural block diagram of an aluminum electrolysis energy balance control system in some embodiments of the present application, including: a temperature detection module 100, an energy balance control module 200, and an execution module 300.

[0087] The temperature detection module 100 is used to detect the current ambient temperature and the current busbar temperature of the target electrolytic aluminum series, which can be achieved by installing a busbar temperature meter and an ambient temperature meter at the busbar end of the target electrolytic aluminum series.

[0088] Among them, the energy balance control module 200 is used to determine the first temperature difference between the current ambient temperature of the target electrolytic aluminum series and the set ambient temperature, and the second temperature difference between the current large bus temperature and the set large bus temperature; it is also used to determine the current intensity adjustment parameter and the fan opening adjustment parameter according to the first temperature difference and the second temperature difference when the first temperature difference exceeds the first preset range and the second temperature difference exceeds the second preset range; it is also used to issue control instructions to the execution module 300.

[0089] The specific execution method of the energy balance control module 200 can be performed according to the implementation shown in the above S120, and this application will not elaborate on it here.

[0090] The execution module 300 is configured to adjust the current intensity and the fan opening of the target electrolytic aluminum series according to the current intensity adjustment parameter and the fan opening adjustment parameter.

[0091] In some embodiments, the execution module 300 includes a power supply control system 310 and a high-voltage fan 320; the power supply control system 310 is used to receive the current intensity control instruction issued by the energy balance control module 200, and adjust the current intensity of the target electrolytic aluminum series according to the current intensity adjustment parameter; the high-voltage fan 320 is used to receive the fan opening control instruction issued by the energy balance control module 200, and adjust the fan opening of the target electrolytic aluminum series according to the fan opening adjustment parameter.

[0092] In order to enable those skilled in the art to better understand the technical solution of the present application and the beneficial effects of the technology of the present application, the following five embodiments and five comparative examples are used for illustration.

At 11:00 PM on October 29, the busbar temperature was 36.2°C, when the air temperature was 4°C.
