Abstract
Description
Technical Field
[0001] This invention relates to the field of cement kiln co-processing technology, and in particular to a safety monitoring system and method for cement kiln co-processing optimized for variable operating conditions. Background Technology
[0002] Cement kiln co-processing technology utilizes the high-temperature environment and alkaline atmosphere during cement production to effectively decompose harmful organic compounds such as dioxins and solidify heavy metals, thereby achieving the harmlessness, reduction, and resource utilization of waste.
[0003] However, existing cement kiln co-processing systems still have many shortcomings. The substitute materials used in co-processing contain various polluting elements. If the cement kiln process control is not accurate enough, environmental safety issues can arise, necessitating enhanced safety monitoring. Furthermore, because cement kilns need to process different raw materials, they must switch between various operating conditions, including conventional coal-fired production and co-processing of different substitute types. This poses a significant challenge to traditional cement kiln production processes. If the cement kiln's operating conditions change but the system's control parameters fail to adapt, equipment malfunctions can occur. For example, when the substitute material is chlorine-containing compounds from municipal solid waste or industrial waste, chlorine volatilizes at high temperatures and combines with alkali metals to form low-melting-point chlorides, which condense and deposit on the preheater's inner wall, leading to a significantly increased scaling rate. Therefore, it is necessary to adjust the bypass fan in the process parameters to reduce the content of gaseous chlorine. In addition, the temperature of the decomposition furnace in co-processing mode is higher than in conventional coal-fired mode to increase the degree of decomposition. If the decomposition furnace temperature is not increased in co-processing mode, incomplete decomposition of toxic substances in the substitute material can occur, causing environmental safety issues. However, how to optimize the entire cement kiln control system based on changing operating conditions remains an unsolved problem in current technology. Therefore, it is necessary to design a monitoring and control system that is compatible with multiple operating conditions, automatically matches and optimizes production control parameters, and can ensure the safe production of the cement kiln system.
[0004] Existing invention patent application CN119143414A proposes a construction waste treatment system and method based on cement kiln co-processing. The system includes a construction waste treatment system, a lightweight material crushing system, an alternative fuel conveying and processing system, a raw material conveying system, and a cement production system. The system has two construction waste inlets, allowing it to handle both renovation and demolition waste, thus offering wide adaptability. This invention patent application fully utilizes the characteristics of cement production to cleanly process construction waste. Through the construction waste treatment system and the lightweight material crushing system, the construction waste is processed into aggregates, powders, and lightweight materials. The resulting aggregates and powders can be used as raw materials for cement production, while the lightweight materials can be used as alternative fuels for cement production, improving resource recycling rates, reducing cement production costs, and reducing carbon emissions. However, this invention patent application does not solve the aforementioned technical problems. Summary of the Invention

[0061] Example 1:
[0062] This invention provides a safety monitoring system for co-processing in cement kilns optimized for varying operating conditions. Please refer to the following for details. Figure 1 , Figure 1 A schematic diagram of a safety monitoring system for co-processing cement kilns optimized for varying operating conditions, provided in an embodiment of the present invention, is shown. The system includes:
[0063] Cement kiln production system, cement kiln storage system, on-site production control platform, storage monitoring host, operating condition control server;
[0064] The cement kiln production system includes a decomposition furnace and a pretreatment device; the cement kiln storage system stores coal raw materials and alternative raw materials.
[0065] The on-site production control platform is used to determine the current working condition based on the current raw material information, and to activate and control the associated production controller based on the target working condition;
[0066] The storage monitoring host is used to obtain alternative operating conditions based on the stored raw material information;
[0067] The operating condition control server is used to determine the cement kiln change operating condition control point based on the current raw material consumption information, and to select the target operating condition based on the current raw material type, the stored raw material type and the current equipment workload.
[0068] Preferably, it also includes a production information acquisition device and a sensing device for the storage system;
[0069] The production information acquisition device obtains the current raw material information and sends it to the on-site production control platform; the production information acquisition device is a sensor installed on the production site, including but not limited to scanning devices, visual recognition devices, and RFID recognition devices.
[0070] The on-site production control platform determines the current operating condition based on the current raw material information. If the current raw material information is coal, the current operating condition is determined to be a coal-fired operating condition; if the current raw material information is a substitute raw material, the current operating condition is determined to be a collaborative processing operating condition.
[0071] The production information acquisition device is used to acquire current raw material information and send it to the on-site production control platform;
[0072] The sensing device of the storage system is used to collect information on the stored raw materials, including the type of stored raw materials.
[0073] Preferably, the operating condition control server obtains the raw material consumption curve under the current operating condition, and obtains the raw material consumption rate curve after differential operation;
[0074] Obtain the average consumption rate of the raw material consumption rate curve during the steady-state period;
[0075] Obtain the remaining amount and storage quantity of the current raw materials;
[0076] The remaining consumption time of the current raw material is analyzed based on the average consumption rate, the current remaining amount of raw material, and the current storage amount of raw material.
[0077] Let the time point when the remaining time consumed is less than or equal to the preset time threshold be the variable operating condition control point.
[0078] Preferably, the sensing device of the storage system collects information about the stored raw materials, including the type of stored raw materials; the sensing device of the storage system includes, but is not limited to, a scanning device, a visual recognition device, and an RFID recognition device.
[0079] The storage monitoring host acquires information about the stored raw materials, obtains the type of stored raw material that is different from the current raw material type, and obtains the matching alternative operating conditions;
[0080] The storage monitoring host sends the matching alternative operating conditions to the operating condition control server.
[0081] Preferably, the operating condition control server selects the target operating condition based on the current raw material type, the stored raw material type, and the current equipment workload;
[0082] Preferably, the operating condition control server analyzes the workload intensity R1 of the pretreatment equipment and the workload intensity R2 of the decomposition furnace; if the workload intensity R1 of the pretreatment equipment is greater than a first intensity threshold and the workload intensity R2 of the decomposition furnace is greater than a second intensity threshold, then the target operating condition is set to a coal-fired operating condition.
[0083] The workload intensity R is calculated based on the continuous working time and the working power. The longer the continuous working time, the higher the workload intensity R, and the higher the working power, the higher the workload intensity R. Optionally, the workload intensity R = w1 × continuous working time / working time threshold + w2 × working power / rated power, that is, the weighted average method is used to comprehensively consider the continuous working time and the working power. The weighting coefficients w1 and w2 can be obtained according to empirical values, or w1 = w2 = 0.5 can be set to simplify the calculation.
[0084] Because the pretreatment unit and the decomposition furnace are under heavy load, and the alternative raw materials require more pretreatment and higher decomposition furnace temperatures, it is necessary to switch to conventional coal-fired operation to reduce the load and improve equipment safety.
[0085] Preferably, the operating condition control server sends the target operating condition to the on-site production management and control platform, and the on-site production management and control platform selects the associated production controller based on the target process of the target operating condition;
[0086] The associated production controller obtains the process parameters for the target operating condition and adjusts them to the preset target value.
[0087] The associated production controllers include different types of pretreatment controllers and decomposition furnace temperature controllers. After receiving the target operating condition selected by the operating condition control server, the on-site production management platform calls the target process parameters from the database, selects the pretreatment module to be activated, and sends the process parameters to the pretreatment controller and decomposition furnace temperature controller. This achieves distributed safety monitoring of the entire cement kiln monitoring system, improving monitoring efficiency. Furthermore, each associated production controller monitors production information parameters and equipment status parameters during the production process, sending warning information to the monitoring terminal of remote monitoring personnel in case of anomalies, preventing equipment failure and environmental pollution, and improving the control capabilities for equipment safety and environmental safety.
[0088] Example 2:
[0089] This invention also provides a safety monitoring method for co-processing in cement kilns optimized for varying operating conditions; please refer to the following for details. Figure 2 , Figure 2 A flowchart of a safety monitoring method for co-processing in cement kilns optimized for varying operating conditions, provided by an embodiment of the present invention, is shown below. The method includes the following steps:
[0090] S1. Determine whether the current operating condition is coal-fired or co-processing based on the current production information of the cement kiln; the current production information includes the current raw material information;
[0091] Preferably, S1 includes:
[0092] S11. The production information acquisition device acquires the current raw material information and sends it to the on-site production control platform; the production information acquisition device is a sensor installed on the production site, including but not limited to scanning devices, visual recognition devices, and RFID recognition devices.
[0093] S12. The on-site production control platform determines the current operating condition based on the current raw material information. If the current raw material information is coal, the current operating condition is determined to be a coal-fired operating condition; if the current raw material information is a substitute raw material, the current operating condition is determined to be a collaborative processing operating condition.
[0094] S2. The operating condition control server determines the cement kiln change operating condition control point based on the current raw material consumption information.
[0095] The variable operating condition control point is the time point for controlling the switching of cement kiln operating conditions; the current raw material consumption information includes the current consumption amount, remaining amount, and remaining consumption time of the raw materials.
[0096] Please refer to the details. Figure 3 , Figure 3 A flowchart of a method for determining the control point of cement kiln transformation condition based on the current raw material consumption information provided in this embodiment of the invention includes:
[0097] S21. Obtain the raw material consumption curve under the current working condition, and obtain the raw material consumption rate curve after differential operation.
[0098] S22. Obtain the average consumption rate V of the raw material consumption rate curve during the steady-state period;
[0099] S23. Obtain the remaining amount of raw material Q1 and the current storage amount of raw material Q2;
[0100] S24. Analyze the remaining consumption time T of the current raw material based on the average consumption rate, the remaining amount of the current raw material, and the storage amount of the current raw material; where T = (Q1 + Q2) / V.
[0101] S25. Let the time point when the remaining time consumed is less than or equal to the preset time threshold be the variable operating condition control point.
[0102] Furthermore, there may be a certain distance between the current production system and the storage system. This distance varies between different cement kiln systems, so a certain transportation time is required from the storage system to the production system. However, for a given cement kiln system, this transportation time is fixed. Therefore, this invention simplifies the process and does not consider the transportation time here.
[0103] S3. The storage monitoring host obtains alternative operating conditions based on the stored raw material information and sends them to the operating condition control server.
[0104] S31. The sensing device of the storage system collects information on the stored raw materials, including the type of stored raw materials;
[0105] S32. The storage monitoring host obtains the storage raw material information, obtains the storage raw material type that is different from the current raw material type, and obtains the matching alternative operating conditions;
[0106] S33. Send the matched alternative operating conditions to the operating condition control server.
[0107] If the type of stored raw material includes coal, then the alternative operating conditions include coal-fired operating conditions;
[0108] If the type of stored raw material includes alternative raw materials, then the alternative operating conditions include co-processing operating conditions; further, the alternative raw materials include multiple types of alternative raw materials, including but not limited to industrial solid waste fly ash, blast furnace slag, coal gangue, waste gypsum, diatomaceous earth, waste incineration ash, fly ash, contaminated soil, and carbide slag; optionally, the alternative raw materials include first alternative raw materials and second alternative raw materials; correspondingly, the alternative operating conditions include first co-processing operating conditions and second co-processing operating conditions;
[0109] Therefore, in this embodiment, the types of stored raw materials include coal, a first alternative raw material, and a second alternative raw material; the alternative operating conditions include coal-fired operating conditions, a first co-processing operating condition, and a second co-processing operating condition.
[0110] The type of stored raw material is different from the current raw material, because the same type of raw material has already been used in the time calculation in S2.
[0111] S4. The operating condition control server selects the target operating condition based on the current raw material type, the stored raw material type, and the current equipment workload.
[0112] Please refer to the details. Figure 4 , Figure 4 A flowchart of a method for selecting a target operating condition based on the current raw material type, the stored raw material type, and the current equipment workload, provided in an embodiment of the present invention, includes:
[0113] S41. Determine whether the current raw material type is a substitute raw material. If yes, proceed to S42; otherwise, proceed to S44.
[0114] S42. Determine whether the type of stored raw material includes coal. If yes, proceed to S43; otherwise, proceed to S44.
[0115] S43. Analyze the working load intensity R1 of the pretreatment equipment and the working load intensity R2 of the decomposition furnace; if the working load intensity R1 of the pretreatment equipment is greater than the first intensity threshold and the working load intensity R2 of the decomposition furnace is greater than the second intensity threshold, then let the target working condition be the coal-fired working condition.
[0116] The workload intensity R is calculated based on the continuous working time and the working power. The longer the continuous working time, the higher the workload intensity R, and the higher the working power, the higher the workload intensity R. Optionally, the workload intensity R = w1 × continuous working time / working time threshold + w2 × working power / rated power, that is, the weighted average method is used to comprehensively consider the continuous working time and the working power. The weighting coefficients w1 and w2 can be obtained according to empirical values, or w1 = w2 = 0.5 can be set to simplify the calculation.
[0117] Because the pretreatment unit and the decomposition furnace are under heavy load, and the alternative raw materials require more pretreatment and higher decomposition furnace temperatures, it is necessary to switch to conventional coal-fired operation to reduce the load and improve equipment safety.
[0118] S44. Determine whether the stored raw material type includes at least one second alternative raw material that is different from the current raw material type; otherwise, end.
[0119] If there is only one type of the second alternative raw material, then the target working condition is the second co-processing working condition corresponding to the second alternative raw material;
[0120] If the second alternative raw material includes multiple types, then the second production process parameters corresponding to each second alternative raw material are obtained, the pretreatment equipment used and the decomposition furnace temperature used in each second production process parameter are analyzed, and a target operating condition sequence is generated.
[0121] First, sort the various alternative raw materials in order of increasing number of pretreatment devices used in each of the second production process parameters;
[0122] Due to the limited variety of pretreatment equipment, there may be situations where different second alternative raw materials use the same type and number of pretreatment equipment. In such cases, these second alternative raw materials are grouped together and occupy the same sorting sequence number.
[0123] Then, according to the temperature of the decomposition furnace in each second production process parameter from low to high, the various second substitute raw materials are sorted in a second order to obtain the target working condition sequence;
[0124] The secondary sorting is to determine the order of multiple second alternative raw materials within a group that occupy the same primary sorting sequence number, thereby obtaining the target operating condition sequence.
[0125] S5. The on-site production control platform activates associated production controllers to monitor production safety based on target operating conditions.
[0126] S51, The working condition control server sends the target working condition to the on-site production management and control platform, and the on-site production management and control platform selects the associated production controller based on the target process of the target working condition.
[0127] S52. The associated production controller obtains the process parameters of the target operating condition and adjusts them to the preset target value.
[0128] The associated production controllers include different types of pretreatment controllers and decomposition furnace temperature controllers. After receiving the target operating condition selected by the operating condition control server, the on-site production management platform calls the target process parameters from the database, selects the pretreatment module to be activated, and sends the process parameters to the pretreatment controller and decomposition furnace temperature controller. This achieves distributed safety monitoring of the entire cement kiln monitoring system, improving monitoring efficiency. Furthermore, each associated production controller monitors production information parameters and equipment status parameters during the production process, sending warning information to the monitoring terminal of remote monitoring personnel in case of anomalies, preventing equipment failure and environmental pollution, and improving the control capabilities for equipment safety and environmental safety.
