[0021] In some embodiments, the online heating control method for the oil phase solution of emulsion explosives provided in this application can be applied to electronic devices or cloud servers. The electronic device can be any mobile terminal or fixed terminal. The terminal can be a device that provides voice and / or data connectivity to the user.

[0022] In some embodiments, such as Figure 1As shown, an online heating control method for an emulsion explosive oil phase solution is provided, used to control the heating system to heat the oil phase solution and combine it with the aqueous phase solution to generate an emulsion explosive; the heating system includes a first pipeline and a second pipeline; the method includes the following steps: S101, obtain the first starting temperature of the first oil phase solution.

[0023] In this embodiment, the aqueous phase solution can be a solution mainly composed of ammonium nitrate. For example, the aqueous phase solution can be a mixture of ammonium nitrate, sodium nitrate, and water.

[0024] In this embodiment, the first oil phase solution can be a composite oil phase. For example, the first oil phase solution can be a mixture of diesel oil, castor oil, and an emulsifier; or it can be a mixture of at least one of rice bran wax, stearic acid, rosin, paraffin wax, and wax paste.

[0025] In one embodiment, the electronic device can collect and record the temperature of the first oil phase solution and / or aqueous phase solution in real time through a temperature sensor or other device installed in the heating system.

[0026] S102, in the current heat exchange stage, the first oil phase solution is heat-exchanged according to a heat exchange path matching the first starting temperature to obtain a second oil phase solution after heat exchange; wherein, the step of heat exchange of the first oil phase solution according to a heat exchange path matching the first starting temperature to obtain a second oil phase solution after heat exchange includes one of the following: Method 1: When the initial temperature is less than the temperature threshold, the first oil phase solution is heated using the first pipeline to obtain the second oil phase solution; wherein, the first pipeline is an ammonium nitrate solution delivery pipeline; the temperature of the ammonium nitrate solution is greater than or equal to 90 degrees Celsius. The second method involves heating the first oil phase solution using the second pipeline when the second initial temperature is greater than or equal to the temperature threshold, thereby obtaining the second oil phase solution; wherein the second pipeline is an aqueous phase solution delivery pipeline; and the aqueous phase solution includes the ammonium nitrate solution.

[0027] In one embodiment, in a conventional emulsion explosive preparation process, it is typically necessary to cool the high-temperature aqueous solution until it meets the process requirements. To reduce energy consumption during the emulsion explosive preparation process, the heat released during the cooling of the ammonium nitrate solution and / or the aqueous solution can be used to heat the first oil phase solution, achieving heat exchange and thus reducing both the energy consumption for oil phase heating and the energy consumption for aqueous phase cooling.

[0028] In this embodiment of the application, the temperature threshold may include, but is not limited to, 18°C, 20°C, or 21°C.

[0029] In one embodiment, the temperature threshold can be 20°C; when the initial temperature of the first oil phase solution is less than the temperature threshold, the energy required to heat up the first oil phase solution is relatively large; the electronic device can control the first oil phase solution to enter the first pipeline and be heated by the high-temperature ammonium nitrate solution to achieve heat exchange between the first oil phase solution and the ammonium nitrate solution, thereby obtaining the second oil phase solution.

[0030] In one embodiment, when the first initial temperature of the first oil phase solution is greater than or equal to a temperature threshold, the energy required to heat the first oil phase solution is relatively small; the electronic device can control the first oil phase solution to enter the second pipeline and be heated by the aqueous phase solution, thereby realizing heat exchange between the first oil phase solution and the aqueous phase solution to obtain the second oil phase solution.

[0031] In one embodiment, when the initial temperature of the first oil phase solution is much lower than the temperature threshold, the energy required to heat up the first oil phase solution is particularly large; the electronic device can control the first oil phase solution to first enter the first pipeline and be heated by the ammonium nitrate solution; then enter the second pipeline and be heated by the aqueous phase solution to obtain the second oil phase solution, thereby realizing multi-stage heat exchange between the first oil phase solution and the ammonium nitrate solution and the aqueous phase solution.

[0032] In some embodiments, both the first pipeline and the second pipeline are pipe-tracing heat exchange devices; the pipe-tracing heat exchange device consists of an outer pipe and an inner pipe; wherein, the outer pipe is used to transport the first oil phase solution; and the inner pipe is used to transport the ammonium nitrate solution or the aqueous phase solution.

[0033] In one embodiment, the outer tube has an inlet and an outlet at both ends for inputting and discharging the oil phase solution (e.g., a low-temperature first oil phase solution). The outer tube can be made of stainless steel.

[0034] In one embodiment, the inner tube has an inlet and an outlet at both ends for inputting and discharging high-temperature sodium nitrate solution or aqueous solution (a composite solution mainly composed of ammonium nitrate). The inner tube can be made of carbon steel.

[0035] In one embodiment, the heat-conducting sheets are uniformly distributed along the axial direction to increase the heat conduction area. The heat-conducting sheets can be made of copper alloy.

[0036] In some embodiments, when the high-temperature ammonium nitrate solution flows into the inner tube, the narrow space between the inner and outer tubes allows heat to be rapidly transferred through the tube wall to the low-temperature oil phase solution flowing in the outer tube. Furthermore, the heat-conducting fins further enhance heat transfer efficiency, effectively accelerating heat diffusion and exchange. During this process, the temperature of the ammonium nitrate solution gradually decreases, while the first oil phase solution is gradually heated. Ultimately, the ammonium nitrate solution cools to the required process temperature, and the first oil phase solution achieves the desired heating effect, realizing efficient heat recovery and utilization. Thus, by exchanging heat with the first oil phase solution through the first and / or second pipes, the heat from different temperature zones of the ammonium nitrate / aqueous phase solution can be continuously and efficiently utilized. For example, when the first and second pipes are connected in series, the first pipe utilizes the largest temperature difference for rapid heating, and the second pipe utilizes the second largest temperature difference for continued effective heating, further improving heat exchange efficiency, reducing heat exchange time, and lowering energy consumption.

[0037] In the above-mentioned online heating control method for the oil phase solution of emulsion explosives, the heat exchange path is dynamically switched based on the first initial temperature of the oil phase solution during the current heat exchange stage, flexibly adjusting the heating strategy: when the first initial temperature is low (below the temperature threshold), the ammonium nitrate solution delivery pipeline is used for heating, and because the temperature of the ammonium nitrate solution is high, the temperature of the oil phase solution can be quickly increased; while when the initial temperature is high (greater than or equal to the temperature threshold), the aqueous phase solution delivery pipeline is used for a gentler heating treatment; thus, it can ensure that the required process temperature can be reached efficiently under different initial conditions, thereby improving the overall production efficiency; and by distinguishing different heat exchange paths to match the initial temperature of the oil phase solution, unnecessary energy consumption and production costs can be further reduced.

[0038] In some embodiments, the method further includes: If the second initial temperature of the second oil phase solution does not reach the target temperature, the target heating time and / or target heating curve of the current heating stage are determined with the goal of the energy of the current preheating stage being consistent with the energy of the preheating stage under the conventional heating mode; the current preheating stage includes the current heat exchange stage and the current heating stage; Based on the target heating time and / or the target heating curve, the heating device in the heating system is controlled to perform heating control on the second oil phase solution in the current heating stage until the real-time temperature of the second oil phase solution reaches the target temperature.

[0039] In some embodiments, the conventional heating mode refers to the mode in traditional emulsion explosive preparation processes where the oil phase solution is heated to the target temperature required by the process through methods such as steam heat exchange, external electric heating, or microwave heating. The preheating stage of the conventional heating mode only includes the heating stage.

[0040] In some embodiments, for oil phase solutions of the same weight and proportion, the energy required to heat from the same starting temperature to the required process temperature is the same. If the second starting temperature of the second oil phase solution does not reach the target temperature, i.e., the process temperature required for subsequent emulsification is not reached after heat exchange of the first oil phase solution in the current heat exchange stage, the electronic equipment can calculate the energy absorbed by the first oil phase solution in the preheating stage under conventional heating mode and the energy absorbed in the current heat exchange stage according to a preset algorithm, aiming to ensure that the energy of the current preheating stage is consistent with the energy of the preheating stage under conventional heating mode. This allows for the determination of the target heating time and / or target heating curve for heating the second oil phase solution in the current heating stage. Thus, based on the target heating time and / or target heating curve, the energy absorbed by the oil phase solution and the temperature reached after preheating can be precisely controlled, making the energy input relatively stable throughout the preheating stage. This reduces the impact of energy fluctuations on product quality and production rhythm, thereby ensuring the product stability of the emulsion explosive prepared based on the preheated oil phase solution.

[0041] In one embodiment, determining the target heating time for the current heating stage, with the goal of ensuring that the energy of the current preheating stage is consistent with the energy of the preheating stage under conventional heating mode, includes: Obtain the preheating temperature curve under the conventional heating mode; wherein, the preheating temperature curve characterizes the preheating process of the first oil phase solution from the first starting temperature to the target temperature under the conventional heating mode; Based on the preheating temperature curve, the target energy integral under the conventional heating mode is determined; the target energy integral represents the energy absorbed by the first oil phase solution during the preheating stage under the conventional heating mode. The first energy integral is determined based on the first starting temperature and the heat transfer temperature curve; wherein, the heat transfer temperature curve indicates the heat transfer temperature curve generated during the process of obtaining the second oil phase solution after the first oil phase solution undergoes heat transfer. The target heating time is determined based on the difference between the target energy integral and the first energy integral.

[0042] In some embodiments, such as Figure 2As shown, in the coordinate system containing the preheating temperature curve, the horizontal axis can be time, and the vertical axis can be temperature. The electronic device can use the vertical axis containing the first starting temperature of the preheating temperature curve, the horizontal and vertical axes containing the preheating time corresponding to the preheating stage, and the area of ​​the region formed by these axes and the preheating temperature curve as the target energy integral. For example, if the third starting temperature is T1℃, the preheating time is S2s, and the target temperature (real-time temperature) after the preheating time is T3℃, then the target energy integral can be the vertical axis 201 containing T1℃, the horizontal axis 202 and vertical axis 203 containing the preheating time S2, and the area P2 of the region formed by these axes and the preheating temperature curve.

[0043] In some embodiments, such as Figure 2 As shown, the electronic device establishes a heat transfer temperature curve by real-time collecting the temperature of the first oil phase solution in the current heat transfer stage. The electronic device can use the area formed by the first starting temperature of the current heat transfer stage (vertical axis), the heat transfer time of the current heat transfer stage (horizontal axis), and the heat transfer temperature curve as the first energy integral. For example, if the first starting temperature is T1℃, the real-time temperature after heat transfer is T2℃ (i.e., the second starting temperature of the second oil phase solution), and the heat transfer time of the current heat transfer stage is S1s, then the first energy integral can be the vertical axis 201 where T1℃ is located, the horizontal axis 202 and the vertical axis 204 where the heat transfer time S1s is located, and the shaded area P1 formed by the heat transfer temperature curve.

[0044] In some embodiments, determining the target heating time based on the difference between the target energy integral and the first energy integral includes: A second energy integral is determined based on the difference between the target energy integral and the first energy integral; wherein the second energy integral represents the energy required for the second oil phase solution to rise from the second initial temperature to the target temperature; If the heating temperature curve of the current heating stage is the preheating temperature curve, the target heating time is determined based on the second energy integral and the preheating temperature curve.

[0045] In this embodiment, the second starting temperature indicates the initial temperature of the second oil phase solution, that is, the real-time temperature of the first oil phase solution after heat exchange is completed.

[0046] For example, such as Figure 2 As shown in the figure, the second starting temperature is T2℃. The goal is to make the energy of the current preheating stage consistent with the energy of the preheating stage under the conventional heating mode. The second energy integral is the region where P2-P1 is located. The target heating time required for the second oil phase solution to heat from T2℃ to the target temperature T3℃ according to the heating trend consistent with the preheating temperature curve is S3-S1s.

[0047] In this embodiment, on the one hand, energy consumption is a significant cost factor in chemical production. By obtaining the preheating temperature curve under conventional heating mode to determine the target energy integral, the standard energy value required to reach the target temperature can be clearly identified. Combining this with the first energy integral of the current heat exchange stage, the difference between the two is calculated to determine the target heating time, reducing energy waste caused by overheating. For example, in the first stage, if the first oil phase solution has already gained a significant amount of heat after heat exchange, the duration of subsequent heating stages can be reduced, lowering unnecessary energy consumption of the heating device. On the other hand, different batches of oil phase solutions may have different initial temperatures and flow / weight ratios. The target heating time is dynamically adjusted based on the real-time first energy integral. For example, if a batch of oil phase solution has a higher initial temperature and a larger first energy integral after heat exchange, the system will shorten the target heating time, ensuring that the final energy consumption is consistent with the conventional heating mode, achieving precise energy consumption control and reducing production costs.

[0048] In some embodiments, determining the target heating time and / or target heating curve for the current heating stage, with the goal of ensuring that the energy of the current preheating stage is consistent with the energy of the preheating stage under conventional heating mode, includes: The heat exchange time and the second initial temperature of the second oil phase solution are obtained by completing the heat exchange of the first oil phase solution. Based on the preheating temperature curve, determine the preheating time for the first oil phase solution to rise from the first starting temperature to the target temperature under the conventional heating mode, and the first heating time to rise from the first starting temperature to the second starting temperature; The target heating time is determined based on the difference between the preheating time and the heat exchange time. A second energy integral is determined based on the difference between the target energy integral and the first energy integral; wherein the second energy integral represents the energy required for the second oil phase solution to rise from the second initial temperature to the target temperature; The target heating curve is generated based on the target heating time, the first heating time, and the second energy integral.

[0049] For example, such as Figure 3As shown, the electronic device can determine the preheating time of the first oil phase solution from the first starting temperature to the target temperature in the conventional heating mode as S2s based on the preheating temperature curve 20; the heat exchange time of the first oil phase solution to obtain the second oil phase solution after heat exchange is S5s; the target heating time is determined as S2-S1s based on the difference between the preheating time and the heat exchange time; the target energy integral is the area of ​​the region corresponding to P2, the first energy integral is the shaded area corresponding to P1, and the second energy integral is the area of ​​the region corresponding to P2-P1; the target heating curve 10 is generated based on the target heating time S2-S1, the first heating time S5, and the second energy integral P2-P1.

[0050] In some embodiments, generating the target heating curve based on the target heating time, the first heating time, and the second energy integral includes: If the first heating time is greater than the heat exchange time, then it is determined that the heating trend represented by the target heating curve is slower than the heating trend represented by the preheating temperature curve. If the first heating time is less than or equal to the heat exchange time, then the heating trend represented by the target heating curve is determined to be faster than or equal to the heating trend represented by the preheating temperature curve.

[0051] In this embodiment, the heating trend is used to characterize the rate at which the temperature of the oil phase solution (such as the second oil phase solution) rises during the current heating stage.

[0052] For example, such as Figure 3 As shown, from Figure 3 As can be seen, the first heating time S5 is greater than the heat exchange time S1. During the heat exchange time S1, the energy absorbed by the first oil phase solution under the conventional heating mode is less than the energy absorbed in the current heat exchange stage. Therefore, the heating trend represented by the target heating curve 10 is slower than the heating trend represented by the preheating temperature curve 20.

[0053] In traditional chemical production, even slight temperature differences can lead to fluctuations in product quality. In this embodiment, the target heating time is precisely calculated to ensure consistent preheating time. Based on the target heating time, the first heating time, and the second energy integral, a target heating curve is generated. This ensures that each batch of products maintains consistent preheating time while keeping energy input consistent. On one hand, this reduces quality fluctuations caused by energy factors, improves product qualification rate and stability, and enhances product market competitiveness. On the other hand, it maintains consistency in the production process, allowing production personnel to monitor the preheating process in real time, ensuring that preheating time matches the production rhythm, and reducing the possibility of production line shutdowns due to excessively long preheating times for a particular batch.

[0054] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

The solution provided by this device is similar to the solution described in the above method.
