Abstract
Description
Technical Field
[0001] This invention relates to the field of concrete mixing management technology, specifically to a concrete mixing plant management system and method. Background Technology
[0002] As the global goal of carbon neutrality is advanced, the concrete industry faces pressure to reduce carbon emissions. As the core of low-carbon production, carbon dioxide mineralization technology needs to optimize carbon dioxide supply strategies and mineralization control. At the same time, industrial wastewater reuse and resource recycling have become essential requirements for green production, driving the upgrading of mixing plants towards intelligence, low carbon, and circularity to meet the needs of environmental protection and sustainable development.
[0003] The existing concrete mixing plant management system and method have at least the following technical problems: 1. The existing technical solution lacks analysis on carbon dioxide mineralization management in the concrete production process, which makes it impossible to achieve the goal of low-carbon and environmentally friendly production. At present, the construction industry is actively promoting the carbon neutrality process. As the most important building material, the carbon emission control in the production process of concrete is crucial. The lack of analysis on the direction of mineralization reaction using carbon dioxide in industrial waste gas makes it impossible to permanently solidify carbon dioxide in concrete through chemical reaction. This will cause the mixing plant to miss an important technical path to reduce carbon emissions. It will not be able to respond to the dual carbon requirements, nor can it meet the mandatory indicators for low-carbon concrete in the green building evaluation standards. Ultimately, this will cause the product to lose its environmental advantage in market competition.
[0004] 2. Most concrete mixing plant management systems and methods lack a chemical reaction-based mixing ratio optimization mechanism, leading to raw material waste and unstable product quality. Furthermore, they lack the establishment and analysis of a synergistic control model for cement hydration and carbon dioxide mineralization reactions, making it impossible to accurately control the reaction equivalent of calcium hydroxide and carbon dioxide. This results in insufficient or excessive mineralization. Insufficient mineralization leads to a low carbon dioxide fixation rate, while excessive mineralization causes early strength problems in concrete, thus significantly increasing production costs.
[0005] 3. Existing concrete mixing plant management systems and methods lack a closed-loop wastewater reuse management system, leading to water waste and environmental pollution. While some management systems and methods include a truck cleaning module within the mixing plant, they lack a wastewater treatment and reuse mechanism. This lack of wastewater management further exacerbates the problem. Key technical modules such as value monitoring, sodium carbonate neutralization calculation, and settling rate analysis fail to improve wastewater recycling rates, resulting in an additional 0.2 to 0.3 tons of industrial water consumption per cubic meter of concrete production. Simultaneously, the discharged alkaline wastewater damages the surrounding soil. The increased value caused vegetation damage. Summary of the Invention
[0006] The purpose of this invention is to provide a concrete mixing plant management system and method, which solves the problems existing in the background art.
[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a concrete mixing plant management system, including: a mineralization supply process management module, used to analyze the carbon dioxide supply situation in the corresponding carbon dioxide mineralization process before concrete mixing when a designated mixing plant uses carbon dioxide mineralization to produce low-carbon concrete, and then generate a carbon dioxide supply strategy.
[0008] The mineralization control optimization module is used to mix concrete based on the carbon dioxide supply during the carbon dioxide mineralization process and to evaluate whether the carbon dioxide mineralization meets the requirements. If the carbon dioxide mineralization does not meet the requirements, the carbon dioxide supply strategy is adjusted.
[0009] The mixing ratio optimization management module is used to analyze the ratio of admixtures when mixing concrete, when the carbon dioxide mineralization meets the requirements, and then to mix the concrete.
[0010] The water circulation management module for the mixing process is used to manage the wastewater reuse process generated during concrete mixing when the concrete is being mineralized.
[0011] In a second aspect, the present invention provides a method for managing a concrete mixing plant, comprising: Step 1, mineralization supply process management: when a designated mixing plant uses carbon dioxide mineralization to produce low-carbon concrete, the carbon dioxide supply situation in the corresponding carbon dioxide mineralization process before concrete mixing is analyzed, and a carbon dioxide supply strategy is generated.
[0012] Step 2, Mineralization Control Optimization: Based on the carbon dioxide supply during the carbon dioxide mineralization process, the concrete is mixed and the carbon dioxide mineralization is evaluated to determine if it meets the requirements. If the carbon dioxide mineralization does not meet the requirements, the carbon dioxide supply strategy is adjusted.
[0013] Step 3, Mixing Proportion Optimization Management: When the carbon dioxide mineralization meets the requirements, analyze the proportion of the admixtures when mixing the concrete, and then carry out the mineralization mixing of the concrete.
[0014] Step 4: Water circulation management during the mixing process: When concrete is being mineralized, manage the wastewater reuse process generated during concrete mineralization mixing.
[0015] The beneficial effects of the present invention are as follows: 1. The concrete mixing plant management system and method provided by the embodiments of the present invention, in the management of the carbon dioxide mineralization supply process, through a comprehensive analysis of the carbon dioxide supply situation, is conducive to providing a precise carbon dioxide supply strategy for concrete production. This process not only considers the utilization of carbon dioxide in the exhaust gas, but also scientifically calculates the carbon dioxide input rate by combining it with the molar mass of calcium hydroxide and carbon dioxide, ensuring the efficiency and accuracy of the mineralization process, which is conducive to ensuring that the carbon dioxide supply is precisely matched with the needs of concrete production, thereby achieving the best balance in terms of environmental protection and cost control.
[0016] 2. In the mineralization control optimization module of this invention, a mechanism for real-time monitoring and evaluation of the carbon dioxide mineralization process is adopted, which helps to ensure the stability of the mineralization process. When it is found that the carbon dioxide mineralization does not meet the requirements, the module automatically adjusts the carbon dioxide supply strategy to ensure the best effect of the mineralization process. The dynamic adjustment mechanism effectively avoids the problem of excessive or insufficient carbon dioxide supply, thereby improving the environmental performance and production efficiency of concrete, and ensuring the quality and sustainability of concrete.
[0017] 3. In the mixing ratio optimization management module of this invention, the precise analysis of the required admixture ratio for concrete mixing is beneficial to improving the overall performance of concrete. By combining the water demand after carbon dioxide mineralization with the amount of admixtures, the scientific and rationality of the ratio is ensured. This not only helps to improve the strength and durability of concrete, but also effectively avoids waste and optimizes resource utilization in the production process. Through optimized management, the final performance of concrete is guaranteed and meets the usage requirements of different application scenarios.
[0018] 4. In the water circulation management module of the mixing process, the present invention monitors and manages the wastewater reuse process, which helps to reduce the environmental burden in the production process. Through standardized control of wastewater reuse, it ensures that production wastewater can be effectively recycled and used in subsequent production processes. This not only helps to improve the efficiency of resource recycling, but also reduces the pollution of wastewater to the environment, and helps to achieve sustainable development in the production process.

[0022] 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.
[0023] Please see Figure 1 As shown, the present invention provides a concrete mixing plant management system, which includes: a mineralization supply process management module, a mineralization control optimization module, a mixing ratio optimization management module, a mixing process water circulation management module, and a database.
[0024] The mineralization supply process management module is connected to the mineralization control optimization module. The mineralization control optimization module is connected to the mixing ratio optimization management module and the database. The mixing ratio optimization management module is connected to the mixing process water circulation management module and the database. The mixing process water circulation management module is connected to the database.
[0025] The mineralization supply process management module is used to analyze the carbon dioxide supply during the corresponding carbon dioxide mineralization process before concrete mixing when a designated mixing plant uses carbon dioxide mineralization to produce low-carbon concrete, and then generate a carbon dioxide supply strategy.
[0026] In one specific embodiment, the analysis of the carbon dioxide supply during the carbon dioxide mineralization process before concrete mixing is carried out as follows: Before using waste carbon dioxide generated in the industrial park for concrete mineralization, the corresponding molar masses are calculated using the chemical formulas of calcium hydroxide and carbon dioxide. The molar masses of calcium hydroxide and carbon dioxide are denoted as follows: and The cement dosage corresponding to the production of a specified amount of concrete is obtained from the designated mixing plant management system. The contents of tricalcium silicate and dicalcium silicate, the main components of the cement, are then calculated. The mass of calcium hydroxide generated during the production of the specified amount of concrete is then recorded as follows: Therefore, the carbon dioxide input rate formula is used: The rate of carbon dioxide input during mineralization was obtained when producing a specified amount of concrete. ,in This represents the time required for carbon dioxide to be fully mineralized from the start of injection.
[0027] It should be noted that the calculation process for obtaining the corresponding molar mass from the chemical formulas of calcium hydroxide and carbon dioxide is the existing method for calculating molar mass using chemical formulas, and will not be elaborated further here. Industrial parks include, but are not limited to, steel plants and chemical plants.
[0028] It should also be noted that, based on the hydration reaction equations of tricalcium silicate and dicalcium silicate, the contents of the main components tricalcium silicate and dicalcium silicate in cement are statistically obtained. This is a standard chemical analysis process and will not be elaborated upon further here. The contents of tricalcium silicate and dicalcium silicate in the corresponding cement of a specified amount of concrete are respectively denoted as... and The process of calculating the mass of calcium hydroxide generated when producing a specified amount of concrete is as follows: First, based on the amount of cement used in the specified amount of concrete... Then, the amount of calcium hydroxide produced per 100 grams of tricalcium silicate and per 100 grams of dicalcium silicate is recorded as follows: and Then, through the calculation formula: To obtain the mass of calcium hydroxide generated when producing a specified amount of concrete. .
[0029] It should also be noted that, taking the carbon dioxide mineralization reaction at a concrete mixing plant as an example, at a stirring speed of 100 rpm and an environment of 20°C, carbon dioxide can completely react with calcium hydroxide within 120 seconds. Therefore, the setting... The stirring time for the carbon dioxide mineralization reaction was set at 2 minutes. In actual production, engineers adjusted this time experimentally; if the carbon dioxide could react completely within 90 seconds, the stirring time was shortened. To improve efficiency, if residual carbon dioxide is still detected after 120 seconds, the time needs to be extended. Or increase the stirring intensity, It is both an empirical parameter and can be dynamically adjusted according to the actual situation.
[0030] In one specific embodiment, the carbon dioxide supply strategy is as follows: based on the carbon dioxide input rate corresponding to the mineralization during the production of a specified amount of concrete. Through the calculation formula: The amount of carbon dioxide injected during mineralization is obtained when producing a specified amount of concrete. When producing concrete mineralization in a specified quantity, it is carried out in a designated mixing plant according to... and The mineralization production of concrete with a specified dosage will be carried out in order to formulate a carbon dioxide supply strategy.
[0031] The mineralization control optimization module is used to mix concrete based on the carbon dioxide supply during the carbon dioxide mineralization process and to evaluate whether the carbon dioxide mineralization meets the requirements. If the carbon dioxide mineralization does not meet the requirements, the carbon dioxide supply strategy is adjusted.
[0032] In one specific embodiment, the process of assessing whether carbon dioxide mineralization meets the requirements is as follows: Retrieve from the database the corresponding values of concrete with a specified dosage during carbon dioxide mineralization. The target range of values, through real-time Monitoring yielded the corresponding data at each set time point. Values corresponding to each time point Value and The values are compared within the target range; if the time point corresponds to... Value greater than If the value corresponds to the upper limit of the target interval, then the carbon dioxide input rate will increase according to the preset carbon dioxide input rate growth step size. If the time point corresponds to... Value less than If the value corresponds to the lower limit of the target range, then the carbon dioxide input rate will be reduced by decreasing the step size according to the preset carbon dioxide input rate. Once the specified amount of concrete has undergone mineralization, the following calculation formula is used: The mass of calcium carbonate generated after the specified amount of concrete mineralization is obtained. ,in Expressed as the molar mass of calcium carbonate.
[0033] It should be noted that the setting process for the preset carbon dioxide input rate increase step and the preset carbon dioxide input rate decrease step is the same as the PID control process based on feedback control principles in existing technologies. This ensures that the system output remains within the preset target range by real-time monitoring and adjustment of the input rate. The values, etc., will not be elaborated upon further here.
[0034] In one specific embodiment, the process of adjusting the carbon dioxide supply strategy is as follows: The mass of calcium carbonate generated after the specified amount of concrete mineralization is... Compared with the preset mineralization standard range, if If the value exceeds the upper limit of the preset mineralization standard range, it indicates that the specified amount of concrete is excessively mineralized. If the value is less than the lower limit of the preset mineralization standard range, it indicates that the specified amount of concrete is not sufficiently mineralized. When the specified amount of concrete is excessively mineralized, the amount of carbon dioxide input will be reduced in subsequent mineralization of the same amount of concrete. When the specified amount of concrete is insufficiently mineralized, the amount of carbon dioxide input will be increased in subsequent mineralization of the same amount of concrete, thereby adjusting the carbon dioxide supply strategy.
[0035] It should be noted that the preset mineralization standard range is set based on the carbonation reaction efficiency, concrete composition, and reaction conditions during the actual production process, such as temperature, humidity, and carbon dioxide concentration. For example, for a specified amount of concrete, after a certain period of carbon dioxide mineralization reaction, the ideal mass of calcium carbonate produced is calculated or experimentally determined to be 10 to 12 kg per ton. Based on this experimental result, the mineralization standard range is set to 10 to 12 kg of calcium carbonate per ton. Then, in actual operation, after each mineralization reaction, the mass of calcium carbonate produced is measured in real time. If the amount of calcium carbonate produced is greater than 12 kg per ton, it indicates over-mineralization; if it is less than 10 kg per ton, it indicates insufficient mineralization.
[0036] It should also be noted that the specific reduction amount corresponding to the reduction in carbon dioxide input is analyzed as follows: If the lower limit of the preset mineralization standard range is 10, then the calculation formula is as follows: To obtain the required amount of carbon dioxide input to reduce. The analysis process for the required increase in carbon dioxide input and the required decrease in carbon dioxide input is the same, and will not be elaborated further here.
[0037] In the mineralization control optimization module of this invention, a mechanism for real-time monitoring and evaluation of the carbon dioxide mineralization process is adopted, which helps to ensure the stability of the mineralization process. When it is found that the carbon dioxide mineralization does not meet the requirements, the module automatically adjusts the carbon dioxide supply strategy to ensure the best effect of the mineralization process. The dynamic adjustment mechanism effectively avoids the problem of excessive or insufficient carbon dioxide supply, thereby improving the environmental performance and production efficiency of concrete, and ensuring the quality and sustainability of concrete.
[0038] The mixing ratio optimization management module is used to analyze the ratio of admixtures when mixing concrete, when the carbon dioxide mineralization meets the requirements, and then to mix the concrete.
[0039] In a specific embodiment, the process of analyzing the proportion of admixtures during concrete mixing is as follows: The required water volume for a specified amount of unmineralized concrete is obtained from the database. and the required amount of admixtures The water demand calculation formula is as follows: This determines the amount of water required for subsequent mixing of the specified concrete after mineralization. ,in This is expressed as the reduction factor for water demand of calcium carbonate.
[0040] Evaluation formula based on admixtures: This determines the amount of admixtures required for subsequent mixing of the specified concrete after mineralization. ,in This represents the set coefficient by which calcium carbonate enhances the activity of the admixture.
[0041] It should be noted that the subsequent mixing operations for concrete with specified dosage after mineralization include adjusting the water-cement ratio, optimizing the admixture ratio, and controlling the consistency and fluidity of the concrete.
[0042] It should also be noted that the coefficient for reducing water demand and the coefficient for increasing admixture activity of calcium carbonate are set based on the impact of the carbonation process on concrete performance. The formation of calcium carbonate changes the microstructure of concrete. In the mineralization reaction of concrete, carbon dioxide reacts with calcium ions in cement to form calcium carbonate, which reduces the water demand of cement. Since the formation of calcium carbonate fills part of the pore structure in concrete, the mineralization process reduces the water demand of concrete. For example, assuming that experimental studies show that when the calcium carbonate content in concrete reaches 10%, the water demand per ton of concrete is reduced by 5%, then the coefficient for reducing water demand of calcium carbonate is set to 0.05. The coefficient for increasing admixture activity of calcium carbonate is set in the same way as the coefficient for reducing water demand of calcium carbonate, and will not be elaborated further here.
[0043] In one specific embodiment, the concrete mixing process is as follows: Based on the specified amount of water required for subsequent mixing after the concrete has undergone mineralization. and the required amount of admixtures This allows for the subsequent mixing and management of concrete with a specified dosage after mineralization.
[0044] In the mixing ratio optimization management module of this invention, the precise analysis of the required admixture ratio for concrete mixing is beneficial to improving the overall performance of concrete. By combining the water demand after carbon dioxide mineralization with the amount of admixtures, the scientific and rationality of the ratio is ensured. This not only helps to improve the strength and durability of concrete, but also effectively avoids waste and optimizes resource utilization in the production process. Through optimized management, the final performance of concrete is guaranteed and meets the usage requirements of different application scenarios.
[0045] The water circulation management module for the mixing process is used to manage the wastewater reuse process generated during concrete mixing when the concrete is being mineralized.
[0046] In one specific embodiment, the process of managing the wastewater reuse generated from concrete mixing is as follows: when the specified amount of concrete has completed the subsequent mixing after mineralization, the wastewater generated from the mixing is monitored. Value, if the wastewater generated during mixing corresponds to The value does not belong to the preset wastewater reuse Within the standard range, the wastewater generated during mixing will be treated... Neutralization, and then through Neutralization assessment formula: The wastewater generated during mixing was obtained. Sodium carbonate required for neutralization process ,in This represents the amount of wastewater generated during mixing. , The wastewater generated during mixing is represented as follows: Standards for wastewater reuse value, The set sodium carbonate neutralization coefficient is expressed as follows, and is evaluated using the wastewater reuse rate assessment formula: The wastewater reuse rate generated after mixing a specified amount of concrete was obtained. , This represents the amount of wastewater that can be reused after calcium carbonate sedimentation, thus enabling the reuse of wastewater generated from concrete mixing of a specified quantity.
[0047] It should be noted that wastewater reuse The standard range is set based on the chemical characteristics of the wastewater generated during concrete mixing, as well as the wastewater's impact on the environment and reuse. The value should be kept within a range that is suitable for reuse and environmentally friendly, typically set between 6.5 and 8.5.
[0048] In a specific embodiment, the evaluation of the calcium carbonate sedimentation process is as follows: the average particle diameter of the corresponding calcium carbonate particles in the wastewater is detected by a laser particle size analyzer, and the density, hydrodynamic viscosity, and calcium carbonate density of the wastewater are retrieved from the database. Then, the sedimentation rate of the corresponding calcium carbonate in the wastewater is obtained by applying Stokes' sedimentation law. If the sedimentation rate of calcium carbonate is less than or equal to a preset threshold for the sedimentation rate of calcium carbonate for wastewater reuse, it indicates that calcium carbonate sedimentation adjustment is required before wastewater reuse. If the sedimentation rate of calcium carbonate is greater than the preset threshold for the sedimentation rate of calcium carbonate for wastewater reuse, it indicates that calcium carbonate sedimentation adjustment is not required before wastewater reuse.
[0049] It should be noted that, based on Stokes' law of settling, the settling rate of calcium carbonate... The calculation formula is as follows: ,in , , and These represent the average particle diameter, density, hydrodynamic viscosity, and calcium carbonate density of the corresponding calcium carbonate particles in the wastewater, respectively.
[0050] It should also be noted that the preset threshold for calcium carbonate settling rate in wastewater reuse is related to the wastewater reuse... The standard range setting is similar and will not be elaborated further here. When the settling rate of calcium carbonate in the wastewater is less than the preset threshold for the settling rate of calcium carbonate for wastewater reuse, flocculants are added or the wastewater is adjusted... To promote the aggregation and sedimentation of calcium carbonate particles, for example, in the process of wastewater reuse, the test results show that the sedimentation rate of calcium carbonate particles in the wastewater is 0.5 cm per hour, while the preset threshold for the sedimentation rate of calcium carbonate in wastewater reuse is 1 cm per hour. Since the actual sedimentation rate is lower than the threshold, calcium carbonate sedimentation needs to be adjusted. At this time, flocculants such as polyacrylamide are selected and the amount added is determined through experiments. If 0.1 g per liter of polyacrylamide is added in the experiment, the aggregation of calcium carbonate particles in the wastewater is accelerated and the sedimentation rate is increased to 1.2 cm per hour, which meets the reuse standard.
[0051] In the water circulation management module of the mixing process, this invention monitors and manages the wastewater reuse process, which helps reduce the environmental burden of the production process. Through standardized control of wastewater reuse, it ensures that production wastewater can be effectively recycled and used in subsequent production stages. This not only helps improve the efficiency of resource recycling but also reduces wastewater pollution to the environment, thus contributing to the sustainable development of the production process.
[0052] The database stores the corresponding values of concrete with a specified dosage during carbon dioxide mineralization. The target range of values is stored, as well as the amount of water and admixtures required when the concrete is not mineralized. It also stores the density, hydrodynamic viscosity and calcium carbonate density of the wastewater.
[0053] Please see Figure 2 As shown, a concrete mixing plant management method includes the following steps: Step 1, mineralization supply process management: When a designated mixing plant uses carbon dioxide mineralization to produce low-carbon concrete, the carbon dioxide supply situation in the corresponding carbon dioxide mineralization process before concrete mixing is analyzed, and a carbon dioxide supply strategy is generated.
[0054] Step 2, Mineralization Control Optimization: Based on the carbon dioxide supply during the carbon dioxide mineralization process, the concrete is mixed and the carbon dioxide mineralization is evaluated to determine if it meets the requirements. If the carbon dioxide mineralization does not meet the requirements, the carbon dioxide supply strategy is adjusted.
[0055] Step 3, Mixing Proportion Optimization Management: When the carbon dioxide mineralization meets the requirements, analyze the proportion of the admixtures when mixing the concrete, and then carry out the mineralization mixing of the concrete.
[0056] Step 4: Water circulation management during the mixing process: When concrete is being mineralized, manage the wastewater reuse process generated during concrete mineralization mixing.
[0057] The present invention provides a concrete mixing plant management system and method. In the management of the carbon dioxide mineralization supply process, through a comprehensive analysis of the carbon dioxide supply situation, it is beneficial to provide a precise carbon dioxide supply strategy for concrete production. This process not only considers the utilization of carbon dioxide in the exhaust gas, but also scientifically calculates the carbon dioxide input rate by combining it with the molar mass of calcium hydroxide and carbon dioxide, ensuring the efficiency and accuracy of the mineralization process. This helps to ensure that the carbon dioxide supply is precisely matched with the needs of concrete production, thereby achieving the best balance between environmental protection and cost control.

Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the concept of the invention or exceed the scope defined in this specification, they should all fall within the protection scope of the present invention.
