Description

Technical Field

[0001] The embodiments of this specification relate to the technical field of electrolytic aluminum and aluminum-based alloys, and in particular to a control method for an electrolytic cell. Background Art

[0002] As a large electricity consumer, aluminum smelting enterprises do not have the ability to adjust the peak with traditional technology. This is because the core equipment, aluminum electrolytic cells, are designed under preset thermal balance conditions. Any power supply that deviates from the preset thermal balance may cause severe overheating or freezing. Due to this limitation, the operation of modern aluminum electrolytic cells has very strict requirements on the quality of power supply. Therefore, as a large electricity consumer, the electrolytic aluminum industry basically has no peak adjustment ability, cannot benefit from renewable energy as a source of electricity, and has low adaptability and flexibility to the power supply system.

[0003] At present, the electrolytic aluminum industry has requirements for the proportion of green electricity application, which requires the electrolytic cell to have a large capacity for "peak regulation". The heat dissipation of the electrolytic side and the upper energy balance control are the key to the stable operation of the electrolytic cell and the realization of flexible production technology. At present, the industry has determined a control strategy based on the furnace and centered on superheat. A regular furnace and appropriate superheat can improve the stability and current efficiency of the electrolytic cell. However, due to the strong corrosiveness of high-temperature electrolytes, there is currently no probe that can detect the electrolyte temperature online for a long time. Engineers can only measure the tank temperature regularly every day through handheld thermocouples, and judge the superheat by the degree of crusting at the aluminum outlet. The trend of changes in the tank temperature and superheat obtained above is used to judge the trend of changes in the energy of the electrolytic cell, and targeted adjustments are made to ensure the energy balance of the electrolytic cell.

[0004] However, the above method cannot accurately reflect the changes in the energy balance of the electrolytic cell in a timely manner. At the same time, it requires engineers to make judgments and adjustments, which places high demands on engineers and poses systemic risks, resulting in lag and subjectivity in energy balance through the above method.

Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0022] In this specification, a control method of an electrolytic cell is provided. This specification also relates to a control device of an electrolytic cell, a host computer device, and a computer-readable storage medium, which are described in detail one by one in the following embodiments.

[0023] Figure 1 is a flow chart of a control method of an electrolytic cell provided in one embodiment of this specification, such as Figure 1 As shown, the method includes: Step 101: The host computer device predicts the change trend of the electrolytic cell based on at least one channel temperature and determines the change trend of the electrolytic cell. The channel temperature is the temperature collected by the thermocouple module of the electrolytic cell.

[0024] In some embodiments, the host computer device includes but is not limited to devices such as laptop computers, servers, desktop computers or mobile phones. The electrolytic cell includes an aluminum electrolytic cell or an aluminum silicon electrolytic cell. The electrolytic cell includes a thermocouple module, which is used to collect channel temperature. The electrolytic cell may include one or more thermocouples. The thermocouple may be located near the cathode carbon block, the thermocouple corresponds to the unloading point, each unloading point corresponds to a thermocouple, and the electrolytic cell includes a cathode carbon block; the thermocouple may also be distributed at the legs of the electrolytic cell. There is no need to measure the temperature of the high-temperature and highly corrosive electrolyte, which reduces the consumption of the probe, and the thermocouple module can collect the channel temperature for a long time.

[0025] The thermocouple is connected to the acquisition terminal, and the acquisition terminal uploads at least one channel temperature to the host computer device.

[0026] The electrolytic cell uses green electricity as energy, but does not have the ability to load peak, which results in the inability of the preset thermal balance of the electrolytic cell to effectively regulate the temperature inside the electrolytic cell. The electrolytic cell has a tendency to develop into a cold cell or a hot cell. The host computer device predicts the trend of the electrolytic cell, that is, predicts the trend of the electrolytic cell developing into a cold cell or a hot cell. The electrolytic cell change trend includes a hot cell trend or a cold cell trend. When the electrolytic cell change trend is a hot cell trend, it indicates that the temperature inside the electrolytic cell is too high, and the host computer device needs to control the electrolytic cell for heat dissipation; when the electrolytic cell change trend is a cold cell trend, it indicates that the temperature inside the electrolytic cell is too low, and the host computer device needs to control the electrolytic cell for heat preservation.

[0027] Step 102: The host computer device generates a side energy change value and / or an upper energy change value based on the change trend of the electrolytic cell.

[0028] In some embodiments, the electrolytic cell has a top, side walls and a bottom. The heat loss from the top is greater than the heat loss from the side walls, and the heat loss from the side walls is greater than the heat loss from the bottom. The heat dissipation or heat preservation of the electrolytic cell is usually controlled by the top and the side walls.

[0029] The side energy change value refers to the energy that needs to be adjusted for the side wall of the electrolytic cell. The upper energy change value refers to the energy that needs to be adjusted for the top of the electrolytic cell.

[0030] According to the different energy that the electrolytic cell needs to adjust, the host computer device can coordinately adjust the side and top of the electrolytic cell to dissipate heat or keep warm. For example, when the electrolytic cell needs less energy to dissipate heat, the host computer device can control the electrolytic cell to only adjust the heat dissipation of the side or the top; when the electrolytic cell needs more energy to dissipate heat, the host computer device can control the electrolytic cell to adjust the heat dissipation of the side and the top at the same time.

[0031] Step 103: The host device generates a side adjustment parameter based on the side energy change value; and / or generates an upper adjustment parameter based on the upper energy change value.

[0032] In some embodiments, the side wall of the electrolytic cell has a temperature control medium, and the heat of the side of the electrolytic cell can be adjusted by adjusting the temperature difference between the temperature control medium and the side wall and / or adjusting the flow rate of the temperature control medium. The side adjustment parameters include the temperature difference between the temperature control medium and the side wall, and / or the side adjustment parameters include the flow rate of the temperature control medium.

[0033] The top of the electrolytic cell is where the flue gas is discharged. The heat of the upper part of the electrolytic cell can usually be adjusted by adjusting the flue gas flow rate of the flue gas. The upper adjustment parameters include the flue gas flow rate of the flue gas.

[0034] Step 104: The host device generates an electrolytic cell adjustment instruction based on the side adjustment parameters and / or the upper adjustment parameters.

[0035] In some embodiments, the electrolytic cell adjustment instructions include side adjustment parameters and / or upper adjustment parameters. An embodiment of the present specification provides a control method for an electrolytic cell, which predicts the change trend of the electrolytic cell based on at least one channel temperature and determines the change trend of the electrolytic cell, wherein the channel temperature is the temperature collected by the thermocouple module of the electrolytic cell; based on the change trend of the electrolytic cell, generates a side energy change value and / or an upper energy change value; based on the side energy change value, generates a side adjustment parameter; and / or, based on the upper energy change value, generates an upper adjustment parameter; based on the side adjustment parameter and / or the upper adjustment parameter, generates an electrolytic cell adjustment instruction, so that the upper computer device determines that the electrolytic cell needs to increase or reduce heat dissipation based on the channel temperature, and then can adjust only the side heat dissipation or only the upper heat dissipation as needed. The heat dissipation, or the heat dissipation of the side and the heat dissipation of the top need to be adjusted; the heat dissipation of the side and / or the heat dissipation of the top that need to be adjusted is analyzed, and when the heat dissipation of the side of the electrolytic cell needs to be changed, the side adjustment parameters are generated; when the heat dissipation of the top of the electrolytic cell needs to be changed, the top adjustment parameters are generated; finally, the electrolytic cell adjustment instructions are generated according to the parameters that need to be adjusted, and the electrolytic cell is controlled to adjust the energy in time. The upper computer equipment controls the electrolytic cell in time, which has strong operability, avoids manual judgment operations, and does not have judgment errors caused by manual subjectivity. The electrolytic cell can use green electricity as energy, which improves the adaptability and flexibility of the electrolytic cell, ensures the energy balance of the electrolytic cell, and improves the adjustment ability of the electrolytic cell.

[0036] The following combination Figure 1 , a control method for an electrolytic cell is further explained.

[0037] In a possible implementation, step 101 may specifically include: the host computer device determines that the electrolytic cell change trend is a hot tank trend based on the channel temperature being greater than a high temperature threshold; or determines that the electrolytic cell change trend is a cold tank trend based on the channel temperature being less than a low temperature threshold.

[0038] In some embodiments, the electrolytic cell includes one or more thermocouple modules, the thermocouple module includes a thermocouple, a metal layer and a non-metal layer, the thermocouple is covered with a metal layer, and the metal layer is covered with a non-metal layer. The thermocouple includes a high temperature resistant thermocouple, the metal layer includes a stainless steel layer, and the non-metal layer includes a silicon nitride layer. Figure 2 is a schematic diagram of a thermocouple module provided in one embodiment of this specification, such as Figure 2 As shown, the thermocouple module uses the thermocouple as the innermost layer, the thermocouple is covered with a stainless steel tube, and the stainless steel tube is covered with a silicon nitride tube. The silicon nitride tube has high hardness, inherent lubricity, and is wear-resistant, which increases the service life of the thermocouple module. The host device receives one or more channel temperatures. When the number of channel temperatures is 1, the host device executes step 101. When the number of channel temperatures is greater than 1, if any channel temperature is greater than the high temperature threshold, it indicates that the electrolytic cell has a tendency to develop into a hot cell, and the electrolytic cell change trend is determined to be a hot cell trend; if any channel temperature is less than the low temperature threshold, it indicates that the electrolytic cell has a tendency to develop into a cold cell, and the electrolytic cell change trend is determined to be a cold cell trend.

[0039] For example, the electrolytic cell includes 8 thermocouple modules, and the thermocouple modules are pre-buried in the electrolytic cell. Figure 3 is a schematic diagram of a pre-buried point provided by an embodiment of this specification, such as Figure 3 As shown, 6 thermocouple modules are buried 5-6 cm below the cathode carbon block. The electrolytic cell has 6 feeding points, each of which corresponds to a thermocouple module. The remaining two thermocouple modules are placed at the extension of the electrolytic cell ( Figure 3 ). The 8 channel temperatures collected include T1, T2, ..., T7 and T8. When one or more channel temperatures Ti are greater than the high temperature threshold Tmax, it indicates that the electrolytic cell has a tendency to develop into a hot tank; when one or more channel temperatures Ti are less than the low temperature threshold Tmin, it indicates that the electrolytic cell has a tendency to develop into a cold tank. i is an integer greater than or equal to 1 and less than or equal to 8.

[0040] Before determining that the electrolytic cell change trend is a hot cell trend, or before determining that the electrolytic cell change trend is a cold cell trend, it also includes: the host computer device obtains the historical channel temperature corresponding to the channel temperature and the thermocouple data corresponding to the channel temperature; generates the channel temperature change trend based on the channel temperature and the historical channel temperature; and determines that the channel temperature is normal based on the channel temperature change trend and the thermocouple data.

[0041] In some embodiments, the host computer device may determine whether the channel temperature greater than the high temperature threshold is normal after determining that the channel temperature is greater than the high temperature threshold; or, after determining that the channel temperature is less than the low temperature threshold, determine whether the channel temperature less than the low temperature threshold is normal; or, after obtaining the channel temperature, determine whether the channel temperature is normal.

[0042] The historical channel temperature corresponding to the channel temperature is the channel temperature previously collected by the thermocouple corresponding to the channel temperature. The thermocouple data corresponding to the channel temperature is the data of the thermocouple module corresponding to the channel temperature.

[0043] The channel temperature change trend reflects the temperature change trend around the thermocouple module over a period of time. The channel temperature change trend includes gradual increase, sudden increase, gradual decrease or sudden decrease.

[0044] Sort the historical channel temperature and channel temperature in chronological order. If the historical channel temperature and channel temperature gradually increase, the channel temperature change trend is gradually increasing, indicating that the heat accumulated in the electrolytic cell gradually increases, and the channel temperature gradually increases, and the change of channel temperature is normal; if the historical channel temperature and channel temperature gradually decrease, the channel temperature change trend is gradually decreasing, indicating that the heat accumulated in the electrolytic cell gradually decreases, and the channel temperature gradually decreases, and the change of channel temperature is normal; if the channel temperature suddenly increases compared with the historical channel temperature, the channel temperature change trend is a sudden increase, indicating that the temperature collected by the thermocouple module has a large fluctuation, and the thermocouple module may fail, resulting in abnormal channel temperature; if the channel temperature suddenly decreases compared with the historical channel temperature, the channel temperature change trend is a sudden decrease, indicating that the temperature collected by the thermocouple module has a large fluctuation, and the thermocouple module may fail, resulting in abnormal channel temperature.

[0045] The thermocouple data may be a parameter of the operation of the thermocouple module, and the host device determines whether the thermocouple module is abnormal based on the thermocouple data, or may be the result of whether the thermocouple module is abnormal.

[0046] The upper computer device determines whether the channel temperature is normal based on the channel temperature change trend and the thermocouple data; when the channel temperature is normal, the step of determining that the electrolytic cell change trend is a hot cell trend or determining that the electrolytic cell change trend is a cold cell trend is executed.

[0047] In a possible implementation, step 102 may specifically include: Step 1021: The host computer device determines a target channel temperature from at least one channel temperature based on a change trend of the electrolytic cell, and determines a temperature threshold, where the temperature threshold corresponds to the target channel temperature.

[0048] In some embodiments, the target channel temperature includes a target high temperature channel temperature. Or target low temperature channel temperature .

[0049] When the electrolytic cell changes in a hot tank trend, the channel temperature greater than the high temperature threshold Tmax is used as the high temperature channel temperature. If the number of high temperature channel temperatures is 1, the high temperature channel temperature is used as the target high temperature channel temperature. ; If the number of high temperature channel temperatures is greater than 1, determine the maximum high temperature channel temperature from multiple high temperature channel temperatures , the maximum high temperature channel temperature is taken as the target high temperature channel temperature, where the target high temperature channel temperature It is also the maximum channel temperature among multiple channel temperatures. The temperature threshold corresponding to the target channel temperature is the high temperature threshold Tmax.

[0050] When the electrolytic cell changes in a cold tank trend, the channel temperature less than the low temperature threshold Tmin is used as the low temperature channel temperature. If the number of low temperature channel temperatures is 1, the low temperature channel temperature is used as the target low temperature channel temperature. ; If the number of low-temperature channel temperatures is greater than 1, determine the minimum low-temperature channel temperature from multiple low-temperature channel temperatures, and use the minimum low-temperature channel temperature as the target low-temperature channel temperature , where the target low temperature channel temperature It is also the minimum channel temperature among multiple channel temperatures. The temperature threshold corresponding to the target channel temperature is the low temperature threshold Tmin.

[0051] Step 1022: The host device generates a total energy change value based on the target channel temperature and the temperature threshold.

[0052] In some embodiments, when the electrolytic cell changes in a hot tank trend, the total energy change value is the energy required to dissipate heat. When the electrolytic cell changes in a cold tank trend, the total energy change value is the energy required to keep warm.

[0053] It is expressed in the form of a formula . Where ΔQ represents the total energy change.

[0054] As shown in the first line of the above formula, when the electrolytic cell change trend is a cold tank trend, the total energy change value ΔQ is determined by the target low temperature channel temperature The total energy change value ΔQ calculated with the low temperature threshold Tmin represents the amount of heat that the electrolytic cell needs to keep warm, and is also the amount of heat that needs to be reduced, ΔQ < 0.

[0055] As shown in the second line of the above formula, when the electrolytic cell change trend is a hot tank trend, the total energy change value ΔQ is determined by the target high temperature channel temperature The total energy change value ΔQ calculated with the high temperature threshold Tmax represents the amount of heat that the electrolytic cell needs to increase, ΔQ>0.

[0056] As shown in the third line of the above formula, the temperature of any channel is greater than or equal to the low temperature threshold and less than or equal to the high temperature threshold, indicating that the internal temperature of the electrolytic cell is normal and there is no need to adjust the electrolytic cell.

[0057] Step 1023: The host device generates a side energy change value and / or an upper energy change value based on the total energy change value.

[0058] In some embodiments, the side energy change value Δ , upper energy change value Δ With constant heat dissipation value Together they make up the total energy change value, such as the constant heat dissipation value is the heat dissipation constant of other parts. Figure 4 Schematic diagram of heat dissipation ratio of an electrolytic cell provided in one embodiment of this specification, such as Figure 4 As shown, the top, sides and bottom of the electrolytic cell will dissipate heat. The heat dissipation of the top is the top heat loss, the heat dissipation of the sides is the side wall heat loss, and the heat dissipation of the bottom is the bottom heat loss; the top heat loss is 50%, the side wall heat loss is 35%, and the bottom heat loss is 15%.

[0059] The total energy change value distribution formula is ΔQ=Δ +Δ + .in, Indicates the heat dissipation coefficient. It can be changed with heat dissipation or heat preservation. For example, when the electrolytic cell needs to dissipate heat, is a positive number; when the electrolytic cell needs to be kept warm, Is a negative number. is a constant.

[0060] The host device can distribute the total energy change value according to the preset energy distribution ratio to generate the side energy change value Δ and the upper energy change Δ For example, the energy distribution ratio is Δ :Δ =30%:70%, total energy change ΔQ minus The energy difference is obtained; the product of the energy difference and 30% is the energy change value of the side, and the product of the energy difference and 70% is the energy change value of the upper part. The energy distribution ratio can also be other values, and the energy distribution ratio is not limited in this application.

[0061] Or the host device obtains the side threshold and the upper threshold. When the side threshold is less than the upper threshold: If the total energy change value is less than or equal to the side threshold, it means that the amount of heat dissipation to be increased or reduced is small, and the energy difference and the side energy change value Δ equal, and let the upper energy change value Δ 0; if the total energy change value is greater than the side threshold and less than or equal to the upper threshold, it indicates that the amount of heat dissipation that needs to be increased or reduced is large, and the energy difference and the upper energy change value Δ Equal, and let the side energy change value Δ 0; if the total energy change value is greater than the upper threshold, it indicates that the heat dissipation that needs to be increased or reduced is very large. The host device can distribute the total energy change value according to the preset energy distribution ratio to generate the side energy change value Δ and the upper energy change Δ When the upper threshold is smaller than the side threshold, reference may be made to the above description of when the side threshold is smaller than the upper threshold, which will not be described in detail here.

[0062] In a possible implementation, the side adjustment parameter includes a side flow rate adjustment value and / or a side temperature difference adjustment value; in step 103, the side adjustment parameter is generated based on the side energy change value, which may specifically include: Step 1031: The host device generates a current side energy value based on the acquired current side parameters.

[0063] In some embodiments, the host computer includes a host computer distributed control system, the host computer distributed control system includes a side temperature online monitoring system, and the side temperature online monitoring system uploads the current side parameters to the host computer device.

[0064] The side parameters include but are not limited to the heat exchange area A of the side wall, the medium flow rate v of the temperature control medium, and the dynamic viscosity of the temperature control medium. Specific heat of the temperature control medium , heat transfer area magnification factor a, medium density of temperature control medium , the surface temperature of the side wall of the electrolytic cell Medium temperature of temperature control medium At least one of the following parameters. The unit of heat exchange area A is square meters ( ), the heat transfer area A is determined according to the tank type; the unit of medium flow rate v is meter per second (m / s); dynamic viscosity The unit is square meters per second ( ); Medium specific heat The unit is joule per (kilogram·degree Celsius) ( ); medium density The unit is kilograms per cubic meter ( ); surface temperature The unit is degrees Celsius ( ); Medium temperature The unit is degrees Celsius ( ). Current Side Parameter is the current value of the Side parameter.

[0065] The host device is based on the heat transfer area magnification factor a and the medium density , medium flow rate v, medium specific heat Dynamic viscosity Generate Convective Heat Transfer Coefficient ; Based on surface temperature With medium temperature Generate heat transfer temperature difference; based on heat exchange area A, convection heat transfer coefficient The side energy value is generated by the heat transfer temperature difference.

[0066] Convective heat transfer coefficient is the coefficient of heat exchange between the side wall and the temperature control medium. The heat dissipation of the side depends on two aspects, namely the convection heat transfer coefficient and the heat transfer temperature difference. The host computer uses the convection heat transfer coefficient formula, based on the heat transfer area magnification coefficient a and the medium density , medium flow rate v, medium specific heat Dynamic viscosity Generate Convective Heat Transfer Coefficient The formula for the convective heat transfer coefficient is . Host computer equipment for medium density , medium flow velocity v and medium specific heat Perform exponential operation to generate the first exponential operation result; multiply the first exponential operation result by the heat transfer area magnification coefficient a to generate the product result; Perform an exponential operation to generate a second exponential operation result; use the ratio of the product result to the second exponential operation result as the convective heat transfer coefficient .

[0067] The host computer uses the side energy formula, heat exchange area A, and convection heat transfer coefficient The side energy value generated by the heat transfer temperature difference The side energy formula is The heat transfer temperature difference is , the upper computer equipment will heat transfer area A, convection heat transfer coefficient The product of the heat transfer temperature difference is taken as the side energy value .

[0068] When the temperature control medium is determined to be constant, the dynamic viscosity of the temperature control medium Specific heat of medium , medium density and the heat transfer area magnification coefficient a are both fixed and unchanging values; since the electrolytic cell remains unchanged, the heat transfer area A is also a fixed and unchanging value, and what changes are the medium flow rate v and the surface temperature With medium temperature , where the heat transfer temperature difference The difference can be expressed as Δt.
