Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of industrial load process model, and particularly relates to a method for analyzing power characteristics and electrolytic tank solution temperature constraints in an electrolytic copper load process and establishing a resource task network model of the process, in particular, to a method and system for establishing an electrolytic copper industrial load resource task network model considering temperature constraints. BACKGROUND

[0002] New power systems urgently need to enhance the operation regulation ability to adapt to the demand of large-scale renewable energy grid connection. The optimization path of system regulation ability covers three dimensions of power supply side, power grid side and demand side. At present, the improvement of regulation ability of power supply side is restricted by economic cost and environmental constraints, and the power grid side faces the balance problem of operation safety, technical bottleneck and investment benefit. Under this background, the development and utilization of demand side resource regulation ability gradually become a research hotspot.

[0003] Among the demand side resources, high-energy-consuming industrial load shows significant regulation potential due to its large adjustable capacity and excellent response characteristics. However, it should be noted that the participation of industrial load in demand response may challenge the production stability. This is mainly due to the production characteristics of high-energy-consuming industries: first, the production processes of different industries are significantly different, and the power demand characteristics of each process link show obvious heterogeneity; second, the production process generally involves complex physical and chemical reactions such as thermodynamics and electrochemistry, and power regulation may break the original material balance state, threatening the production safety boundary. These characteristics together constitute the technical difficulties in formulating power regulation strategies for multi-process industrial loads.

[0004] Among industrial loads, electrolytic copper industrial load is a typical multi-process high-energy-consuming industrial load. The electrolytic copper load process includes: material preparation link, pyrometallurgical copper smelting link, oxygen production link, auxiliary smelting link, electrolytic refining link, and acid production link. The material preparation link provides raw materials for the subsequent pyrometallurgical copper smelting link, the oxygen production link and the auxiliary smelting link provide oxygen-rich air for the pyrometallurgical copper smelting link, the acid production link absorbs the sulfur-containing waste gas generated by the pyrometallurgical copper smelting link to make sulfuric acid, the pyrometallurgical copper smelting link gradually smelts the raw materials to obtain anode copper, and the electrolytic refining link electrolyzes the cast anode copper to obtain product cathode copper. The characteristics of the above process links and the power regulation characteristics of the production equipment are different, there is a material coupling relationship between different process links, power regulation is difficult to coordinate between different process links, and in the production process of the electrolytic refining link, the electrolytic tank solution needs to be maintained within a certain range to ensure the normal deposition of cathode copper. When electrolytic copper participates in grid interaction, power regulation will affect the normal production conditions, and a model is needed that can systematically describe the material interaction state between the process links in the production cycle of electrolytic copper, the power regulation state of the production equipment, and the temperature change of the electrolyte in the electrolytic refining link. SUMMARY

[0005] The purpose of this invention is to address the problem of complex coupling relationships and varying characteristics among different processes in the electrolytic copper industry, making it difficult for these processes to coordinate during power regulation. This invention provides a method for establishing a resource-task network model for electrolytic copper industry loads that considers temperature constraints. Based on the characteristics of the electrolytic copper process flow and the material interactions between processes, the feasibility of power regulation at each process stage is analyzed. The process stages are treated as a whole, with equipment, materials, and electricity in the electrolytic copper process stages abstracted as resources, and the operations of producing / consuming specific sets of resources in each process stage abstracted as tasks. Production safety constraints such as material quantity, output demand, and equipment power regulation, as well as the temperature constraint of the electrolytic cell solution, are considered. Building upon the traditional resource-task network, the energy-temperature coupling relationship of the electrolytic cell solution is further considered to establish an electrolytic cell temperature constraint model. Compared to traditional production scheduling decisions, this model can further characterize the feasible domain for power regulation of the electrolytic copper load.

[0052] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] like Figure 1 As shown, this embodiment of the invention provides a method for establishing a resource task network model for electrolytic copper industrial load considering temperature constraints, comprising: Step 1, analyzing the characteristics of the electrolytic copper load process flow and determining the power regulation characteristics in the electrolytic copper load process flow; Step 2, based on the material coupling relationship and power regulation feasibility between different links in the electrolytic copper load process flow, establishing a resource task network model for the electrolytic copper process flow and obtaining a method for describing the quantity of different materials within the production cycle; Step 3, based on Step 1 and Step 2, establishing a power control model considering the temperature characteristics within the electrolytic cell.

[0054] Specifically, this embodiment of the invention provides the following steps for step one: analyzing the characteristics of the electrolytic copper process and determining the power regulation characteristics of the process. Based on the characteristics of the electrolytic copper load process flow, the electrolytic copper load process flow is as follows: Figure 2 As shown.

[0055] The material preparation stage in the process flow includes subsequent stages such as material transportation and material crushing and mixing. The production equipment in the material transportation stage is a conveyor belt driven by a variable frequency motor. The material transportation speed can be adjusted by changing the frequency. The power consumption of subsequent stages depends on the amount of material, which means that the power of the stage can be adjusted by changing the frequency of the variable frequency motor. Therefore, this stage is a power-adjustable stage.

[0056] The main electrical equipment used in the pyrometallurgical copper smelting process consists of various types of smelting furnaces. These furnaces have complex power characteristics, and the production equipment is non-electrical. Power control mainly regulates the auxiliary smelting equipment. Furthermore, the temperature changes caused by power control have a significant impact on smelting production. Restoring the temperature requires a large amount of coal. Therefore, this process is considered to be a process where power control is not possible.

[0057] The main electrical equipment used in the oxygen production, smelting, and acid production processes are air compressors, blowers, and environmental protection fans. Their power depends on the gas volume. The power consumption can be changed by altering the angle of the inlet guide vanes of the electrical equipment and changing the gas volume. Therefore, the oxygen production, smelting, and acid production processes are power-adjustable processes.

[0058] The main electrical equipment in the electrolytic refining process is the electrolytic cell. Its power characteristics depend on the magnitude of the DC current, which can be altered by changing the voltage drop of the saturated reactor in the electrolytic cell. The electrolytic cell solution has a large thermal inertia, so short-term adjustments have little impact on the solution temperature. Therefore, this stage is considered a power-adjustable stage. To ensure normal production in the electrolytic refining process, the solution temperature needs to be maintained within a certain range. Excessively low temperatures can lead to copper sulfate deposition, affecting the cathode copper deposition efficiency. Therefore, the electrolytic refining stage is also a power-adjustable stage. From the above, it can be seen that in the electrolytic copper load process, the stages with feasible power adjustment are: raw material preparation, oxygen production, intensified smelting, and electrolytic refining.

[0059] Specifically, this embodiment of the invention provides specific steps for step two: based on the material coupling relationship and power control feasibility between process flow stages, a method for describing the quantity of different materials within the production cycle is established. As can be seen from step one, the power characteristics of different production process stages in the electrolytic copper load process vary significantly, and material coupling relationships exist between different stages. The ore, solvent, oxygen, and air in the production process can be considered as raw materials; matte, crude copper, anode copper, and sulfur dioxide can be considered as process products; and sulfuric acid and cathode copper can be considered as products. Raw materials, process products, and products are all resources. The transportation processes between different production stages are all considered tasks. A resource-task network model for the electrolytic copper process is established, as illustrated in the schematic diagram below. Figure 3 As shown.

[0060] The production and consumption of materials in the electrolytic copper process depend on the power control status of the production equipment. Assuming that the power regulation of adjustable production equipment in the electrolytic copper load process includes continuous regulation and switching methods, and that different types of production equipment have different switching characteristics, the power consumption of adjustable production equipment can be expressed as follows:

[0061] (1)

[0062] in, Let k be the power consumed by production equipment k during time period t. N represents the rated power of production equipment k.

[0063] x k t s k t These represent the power regulation and switching states of production equipment k during time period t. Different production equipment have slightly different constraints regarding power regulation and switching states, as detailed below:

[0064] (2)

[0065] (3)

[0066] (4)

[0067] in This indicates a process step that can be continuously controlled and cut. This indicates a process step that cannot be continuously controlled and cut. This refers to a process step that can be continuously controlled but cannot be cut. , These represent the lower and upper limits of power control for production equipment k, respectively. Among them, the side-blown smelting, top-blown smelting, and anode furnace smelting processes in pyrometallurgical copper refining belong to... To avoid affecting the absorption of sulfur-containing waste gas generated in the pyrometallurgical copper smelting process, the acid production process is classified as... All other steps belong to .

[0068] The power regulation and feeding / cutting of production equipment affect the quantity of materials in the process flow. The quantity of materials and its constraints in the electrolytic copper load process flow during the production cycle can be expressed as follows:

[0069] (5)

[0070] (6)

[0071] (7)

[0072] in, Let x be the quantity of material x in time period t. , R represents the quantity of cathode copper at the beginning and end of the production cycle, respectively. xmax and R xmin This refers to the upper limit of the storage space for the material (the upper and lower limits of the material quantity) and the minimum material quantity required to ensure normal production. R represents the quantity of materials produced or consumed by production equipment k during time period t. T is the end of the production cycle. pc R represents the quantity of cathode copper in the product. aim This refers to the demand for cathode copper production, which is the production output required to be met within the production cycle.

[0073] Specifically, this embodiment of the invention provides the following steps for step two: establishing a power control model that considers the temperature characteristics within the electrolytic cell. The power regulation of the electrolytic cell affects the temperature change of the solution within the cell; the principle can be expressed as follows:

[0074] (7)

[0075] Where c and m are the specific heat capacity and mass of the solution in the electrolytic cell, respectively. The temperature of the solution in the electrolytic cell is denoted by t, and t represents a time period within the production cycle, typically 15 minutes or more. This represents the electrical power consumed by the electrolytic cell, specifically the amount of electricity consumed over a given time period.

[0076] The relationship between the temperature changes of the solution in the electrolytic cell during the production cycle and the temperature constraints that need to be met to maintain normal production can be expressed as follows:

[0077] (8)

[0078] (9)

[0079] Among them, P loss This represents the heat loss from the electrolytic cell solution; it indicates the heat lost over a given time period. and The specific heat capacity and mass of the solution in the electrolytic cell. and These are the lower and upper limits of the electrolytic cell solution temperature; This represents the power lost in time period t. This indicates the temperature of the solution in the electrolytic cell and the power of the electrolysis process.

[0080] The electrolytic copper load resource task network considering temperature constraints is based on the process characteristics of electrolytic copper load. It studies the characteristics of production equipment in each process step and the impact of power regulation on the production order. It analyzes the material coupling relationship between different process steps and the temperature characteristics of the electrolytic cell. It can describe the production status of electrolytic copper load during the production cycle and provide a power regulation reference for electrolytic copper load to participate in grid interaction control.

[0081] Specifically, this embodiment of the invention takes the participation of an electrolytic copper industrial load in the grid's time-of-use electricity price demand response as an example. Using the lowest daily production cost as the objective function, it verifies the above-mentioned resource task network model for the electrolytic copper industrial load considering temperature constraints. The specific scenario and electrolytic copper load production data are shown below:

[0082] Assuming the electrolytic copper load participates in the grid demand-side response, with low-price response periods from 12:00 AM to 8:00 AM and from 7:00 PM to 12:00 AM, the adjustable production equipment is the same as analyzed above, the allowable temperature range of the electrolytic copper electrolytic cell solution is 35-40℃, the initial temperature is 40℃, the time scale is 15 minutes, and the response process meets capacity response requirements and load production safety constraints. The electrolytic copper load process, production equipment, main materials, and consumption / production rates are shown below:

[0083] The production stages involved in demand-side response power regulation include: material preparation, oxygen production, intensified smelting, acid production, and electrolytic refining. The corresponding production equipment is, in order: conveyor belt, air compressor, blower, exhaust fan, and electrolytic cell.

The units for the consumption / production material rate data of production equipment are tons or cubic meters, and are uniformly recorded as units. The unit time period is 1 hour.

[0085] Side-blown smelting process: consumes 500 units of ore and solvent, produces 155 units of copper matte, consumes 1090 units of oxygen, consumes 467 units of air, and produces 200 units of sulfur dioxide.

[0086] Top-blown smelting process: consumes 155 units of matte, produces 110 units of crude copper, consumes 345 units of oxygen, consumes 148 units of air, and produces 20 units of sulfur dioxide.

[0087] Anode furnace smelting process: consumes 110 units of crude copper, produces 109 units of anode copper, consumes 140 units of oxygen, consumes 60 units of air, and produces 10 units of sulfur dioxide.

[0088] Electrolytic refining process: 109 units of anode copper are consumed to produce 108 units of cathode copper.

[0089] Oxygen production stage: Produces 1600 units of oxygen.

[0090] Enhanced smelting: Produces 800 units of air.

[0091] Acid production process: Consumes 230 units of sulfur dioxide.

[0092] Based on the resource-task network model considering temperature constraints, the power consumption curves, changes in the quantity of production materials, and changes in the temperature of the electrolytic cell solution during the electrolytic copper industrial load production cycle under the above scenario are as follows: Figures 4-6 As shown.

It considers production safety constraints such as material quantity, output demand, and equipment power regulation, as well as the temperature constraint of the electrolytic cell solution.

[0100] In summary, the present invention addresses the problem that traditional methods that only consider material interaction in resource task networks may violate temperature constraints in the electrolysis process during actual scheduling, potentially affecting actual production order or even causing production safety accidents. By adding temperature constraints, the production order can be further guaranteed when electrolytic copper loads participate in grid interaction.
