Description

Technical Field

[0001] The invention relates to the technical field of electronic digital data processing, in particular to a method for predicting the refractoriness of a combustion furnace liner used for drying compound fertilizers. Background Art

[0002] In the field of compound fertilizer drying technology, with the continuous expansion of industrial production scale and the improvement of production efficiency requirements, the performance of the combustion furnace has a direct impact on the production quality and energy efficiency consumption of compound fertilizers. The fire resistance of the combustion furnace liner is a key factor in determining the service life and stable operation of the combustion furnace. Since the compound fertilizer drying process requires long-term high-temperature heating, the liner material is often faced with greater thermal shock and chemical corrosion, which puts higher requirements on the fire resistance of the material. By optimizing the selection of the liner material in the design stage and performing reasonable temperature control and operation adjustment during the production process, the overall efficiency and safety of the combustion furnace can be improved, providing a more reliable technical guarantee for compound fertilizer drying.

[0003] The prior art, such as the invention patent announcement with announcement number: CN113961996B, discloses a method for fire resistance calculation of an integral structure based on a parametric model. The characteristic of the method is that the fire resistance calculation of the integral structure specifically includes: construction of an integrated information model of the building structure, generation of a parametric fire scenario analysis model, fire scenario simulation, calculation of the temperature rise curve of each component, establishment and solution of the fire resistance calculation model of the integral structure, and fire resistance calculation of the entire structure and adjustment of fire protection measures.

[0004] Prior art, such as a patent application with publication number: CN111553100A, discloses a method for analyzing the fire resistance time of an integral structure based on a fire spread zone. The method is characterized in that a finite element analysis of the fire of the integral structure is used to obtain the overall fire resistance time under different fire development conditions. The specific analysis includes the following steps: setting of a heating zone and a fire spread route, a finite element analysis of the fire of the integral structure, and establishing a quick lookup table. Through the quick lookup table, it is possible to analyze and judge whether the fire resistance time of the integral structure meets the design requirements and whether the structure in which a fire has occurred is close to the fire resistance time.

[0005] In combination with the above scheme, it is found that currently in the field of compound fertilizer drying technology, only the fire resistance monitoring and analysis of the overall structure is usually carried out. However, in the actual application process, there are problems such as the monitoring data is not detailed enough and not targeted enough, which makes the prediction and evaluation of the refractoriness of the inner liner not accurate enough, which not only affects the true evaluation of the refractoriness of the combustion furnace inner liner, and fails to timely discover potential refractory material degradation or damage, but also may lead to the risk of safety hazards in actual operation, affecting the safety and reliability of the compound fertilizer drying process. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a method for predicting the refractoriness of a combustion furnace liner for drying compound fertilizers, which can effectively solve the problems involved in the above-mentioned background technology.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a method for predicting the refractoriness of the inner shell of a combustion furnace for drying compound fertilizers, comprising collecting the operating parameters of the safety equipment of the compound fertilizer drying combustion furnace, performing a safety assessment on the safety equipment of the compound fertilizer drying combustion furnace, analyzing and obtaining the pre-configuration information of the safety equipment of the compound fertilizer drying combustion furnace, and initializing and modulating the safety equipment of the compound fertilizer drying combustion furnace.

[0008] The operation process of the compound fertilizer drying and combustion furnace after initialization modulation is continuously monitored, and the operation process of the compound fertilizer drying and combustion furnace is divided into a fire resistance monitoring stage and a high temperature durability monitoring stage of the compound fertilizer drying and combustion furnace.

[0009] The fire resistance performance monitoring phase of the compound fertilizer drying and combustion furnace is monitored, and the fire resistance performance analysis results of the compound fertilizer drying and combustion furnace are obtained through analysis.

[0010] The high temperature persistence monitoring stage of the compound fertilizer drying and combustion furnace is monitored. Combined with the fire resistance performance analysis results of the compound fertilizer drying and combustion furnace, a comprehensive analysis is performed to obtain the comprehensive prediction and evaluation results of the fire resistance performance of the inner tank, and monitoring and early warning configuration is performed.

[0011] Furthermore, the safety assessment of the compound fertilizer drying and combustion furnace safety equipment is carried out in the following specific process: the operating parameters of the compound fertilizer drying and combustion furnace safety equipment include the normal operating coefficient of the compound fertilizer drying and combustion furnace safety equipment, the sensor abnormality coefficient, the communication abnormality coefficient, the electrical parameter input abnormality coefficient and the average vibration frequency.

[0016] If the pre-configuration information of the compound fertilizer drying and combustion furnace safety equipment is to execute the safety equipment pre-configuration, the difference between the abnormal operation evaluation value of the compound fertilizer drying and combustion furnace safety equipment and the set abnormal operation evaluation threshold value shall be recorded as the compound fertilizer drying and combustion furnace safety equipment adjustment reference value, and the safety equipment configuration parameters shall be obtained according to the compound fertilizer drying and combustion furnace safety equipment adjustment reference value, and the compound fertilizer drying and combustion furnace safety equipment shall be initialized and modulated based on the safety equipment configuration parameters.

[0018] A comprehensive analysis is performed on the fire resistance performance monitoring data of each operating monitoring area of ​​the compound fertilizer drying and combustion furnace to obtain the fire resistance performance index value of the compound fertilizer drying and combustion furnace. The fire resistance performance index value of the compound fertilizer drying and combustion furnace is used to comprehensively quantify the fire resistance of the compound fertilizer drying and combustion furnace in a high temperature environment.

[0019] Furthermore, the analysis obtains the fire resistance performance analysis result of the compound fertilizer drying and combustion furnace, and the specific analysis process is: the fire resistance performance analysis result of the compound fertilizer drying and combustion furnace includes normal fire resistance performance and abnormal fire resistance performance.

[0020] The fire resistance performance index value of the compound fertilizer drying and combustion furnace is compared with the set fire resistance performance index threshold. If the fire resistance performance index value of the compound fertilizer drying and combustion furnace is higher than or equal to the set fire resistance performance index threshold, the fire resistance performance analysis result of the compound fertilizer drying and combustion furnace is marked as normal fire resistance performance; otherwise, the fire resistance performance analysis result of the compound fertilizer drying and combustion furnace is marked as abnormal fire resistance performance.

[0021] Furthermore, the high-temperature persistence monitoring stage of the compound fertilizer drying and combustion furnace is monitored, and the specific process is: the high-temperature persistence monitoring stage of the compound fertilizer drying and combustion furnace is monitored to obtain the high-temperature persistence monitoring data of each operation monitoring area of ​​the compound fertilizer drying and combustion furnace, and the high-temperature persistence monitoring data of each operation monitoring area of ​​the compound fertilizer drying and combustion furnace includes the high-temperature antioxidant coefficient of the inner liner material, the average thermal stress value of the inner liner material, the thermal diffusion coefficient and the average temperature of each operation monitoring area of ​​the compound fertilizer drying and combustion furnace.

[0022] Based on the high-temperature persistence monitoring data of each operating monitoring area of ​​the compound fertilizer drying and combustion furnace, combined with the fire resistance performance index value of the compound fertilizer drying and combustion furnace, a comprehensive prediction and evaluation value of the fire resistance performance of the inner liner of the compound fertilizer drying and combustion furnace is obtained. The comprehensive prediction and evaluation value of the fire resistance performance of the inner liner of the compound fertilizer drying and combustion furnace is used to comprehensively quantify the fire resistance durability and reliability of the compound fertilizer drying and combustion furnace in a high temperature environment.

[0023] Furthermore, the comprehensive analysis obtains a comprehensive prediction and evaluation result of the fire resistance performance of the inner liner. The specific analysis process is: extracting the fire resistance performance analysis result of the compound fertilizer drying and combustion furnace. If the fire resistance performance analysis result of the compound fertilizer drying and combustion furnace is that the fire resistance performance is abnormal, then the comprehensive prediction and evaluation result of the fire resistance performance of the inner liner is directly marked as unqualified for the comprehensive prediction of the fire resistance performance of the inner liner.

[0024] If the fire resistance performance analysis result of the compound fertilizer drying and combustion furnace is that the fire resistance performance is normal, the comprehensive predicted evaluation value of the fire resistance performance of the inner liner of the compound fertilizer drying and combustion furnace will be compared with the set comprehensive predicted evaluation threshold of the fire resistance performance of the inner liner. If the comprehensive predicted evaluation value of the fire resistance performance of the inner liner of the compound fertilizer drying and combustion furnace is higher than or equal to the set comprehensive predicted evaluation threshold of the fire resistance performance of the inner liner, the comprehensive predicted evaluation result of the fire resistance performance of the inner liner will be marked as qualified; otherwise, the comprehensive predicted evaluation result of the fire resistance performance of the inner liner will be marked as abnormal.

[0026] If the comprehensive prediction and evaluation result of the inner liner fire resistance performance is that the comprehensive prediction of the inner liner fire resistance performance is abnormal, the current inner liner fire resistance performance monitoring configuration parameters are added to the set inner liner fire resistance performance monitoring configuration parameter supplementary values ​​to obtain the inner liner fire resistance performance monitoring configuration target adjustment parameters, and the inner liner fire resistance performance monitoring configuration parameters are adjusted up to the inner liner fire resistance performance monitoring configuration target adjustment parameters for monitoring configuration.

[0027] If the comprehensive prediction and evaluation result of the fire resistance performance of the inner liner is that the comprehensive prediction and evaluation result of the fire resistance performance of the inner liner is abnormal, the comprehensive prediction and evaluation result of the fire resistance performance of the inner liner will be sent to the management terminal for early warning at the same time.

[0028] Furthermore, the comprehensive prediction and evaluation value of the fire resistance performance of the inner shell of the compound fertilizer drying and combustion furnace is analyzed under the following specific conditions:

[0036] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] Figure 1 It is a schematic diagram of the method flow of the present invention. DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figure 1 As shown, an embodiment of the present invention provides a technical solution: a method for predicting the refractoriness of the inner shell of a combustion furnace for drying compound fertilizers, comprising collecting operating parameters of the compound fertilizer drying combustion furnace safety equipment, performing a safety assessment on the compound fertilizer drying combustion furnace safety equipment, analyzing and obtaining the pre-configuration information of the compound fertilizer drying combustion furnace safety equipment, and initializing and modulating the compound fertilizer drying combustion furnace safety equipment.

[0040] The operation process of the compound fertilizer drying and combustion furnace after initialization modulation is continuously monitored, and the operation process of the compound fertilizer drying and combustion furnace is divided into a fire resistance monitoring stage and a high temperature durability monitoring stage of the compound fertilizer drying and combustion furnace.

[0041] The fire resistance performance monitoring phase of the compound fertilizer drying and combustion furnace is monitored, and the fire resistance performance analysis results of the compound fertilizer drying and combustion furnace are obtained through analysis.

[0042] The high temperature persistence monitoring stage of the compound fertilizer drying and combustion furnace is monitored. Combined with the fire resistance performance analysis results of the compound fertilizer drying and combustion furnace, a comprehensive analysis is performed to obtain the comprehensive prediction and evaluation results of the fire resistance performance of the inner tank, and monitoring and early warning configuration is performed.

[0043] It should be noted that, in the present embodiment, the compound fertilizer drying and combustion furnace is changed from an internal upper fixed form to a lower support fixed form, a plurality of holes are opened in the inner tank stopper of the compound fertilizer drying and combustion furnace, the heat can be dissipated as quickly as possible, and the inner wall of the inner tank is coated with refractory material to improve the fire resistance of the compound fertilizer drying and combustion furnace. The above modification method can reduce the possibility of deformation of the inner tank due to high temperature during the fertilizer drying process.

[0044] Specifically, a safety assessment is conducted on the compound fertilizer drying and combustion furnace safety equipment, and the specific process is: the operating parameters of the compound fertilizer drying and combustion furnace safety equipment include the normal operating coefficient of the compound fertilizer drying and combustion furnace safety equipment, the sensor abnormality coefficient, the communication abnormality coefficient, the electrical parameter input abnormality coefficient and the average vibration frequency.

[0045] It should be noted that the safety equipment of the compound fertilizer drying and combustion furnace includes fire-fighting equipment, sound and light alarms, and flame detectors.

[0046] It should be noted that the normal operation coefficient of the safety equipment refers to the ratio of the normal operation time of the compound fertilizer drying and combustion furnace safety equipment to the total operation time within a period of time. The status indicator of the monitoring system or the equipment (such as the PLC control system) can be used to detect in real time whether the equipment is in a normal operation state. The sensor abnormality coefficient refers to the ratio of the number of abnormal sensors to the total number of sensors within a period of time. The number of abnormal sensors can be monitored and recorded by the intelligent sensor management system. The communication abnormality coefficient refers to the ratio of the number of communication interruptions or delays of the compound fertilizer drying and combustion furnace safety equipment to the total number of communications. The quality of communication within a period of time is detected by network monitoring instruments (such as network analyzers, status feedback of PLC systems), and the number of communication interruptions or delays is recorded to obtain the communication abnormality coefficient. The electrical parameter input abnormality coefficient is used to measure the abnormality of the input electrical parameters (such as current, voltage, power, etc.). If the input electrical parameters exceed the set range or fluctuate abnormally, it indicates that there may be problems with the electrical system. The number of input abnormalities within a period of time can be monitored by electrical parameter monitoring instruments (such as power analyzers, multimeters), and the ratio of the number of input abnormalities to the total number of inputs is recorded as the electrical parameter input abnormality coefficient. The vibration frequency of the safety equipment within a period of time can be measured by a vibration sensor, and the average value is taken to obtain the average vibration frequency.

[0047] Based on the operation parameter processing of the compound fertilizer drying and combustion furnace safety equipment, an abnormal operation evaluation value of the compound fertilizer drying and combustion furnace safety equipment is obtained, and the abnormal operation evaluation value of the compound fertilizer drying and combustion furnace safety equipment is used to comprehensively quantify abnormal conditions occurring in the safety equipment.

[0048] In this embodiment, the abnormal operation evaluation value of the compound fertilizer drying and combustion furnace safety equipment can be obtained by the following analysis method, and the specific analysis conditions are as follows:

[0049]

[0050] In the formula, α represents the abnormal operation evaluation value of the compound fertilizer drying and combustion furnace safety equipment, R1 represents the normal operation coefficient of the compound fertilizer drying and combustion furnace safety equipment, μ1 represents the abnormal operation evaluation factor corresponding to the set normal operation coefficient, R2 represents the sensor abnormality coefficient of the compound fertilizer drying and combustion furnace safety equipment, μ2 represents the abnormal operation evaluation factor corresponding to the set sensor abnormality coefficient, R3 represents the communication abnormality coefficient of the compound fertilizer drying and combustion furnace safety equipment, μ3 represents the abnormal operation evaluation factor corresponding to the set communication abnormality coefficient, R4 represents the electrical parameter input abnormality coefficient of the compound fertilizer drying and combustion furnace safety equipment, μ4 represents the abnormal operation evaluation factor corresponding to the set electrical parameter input abnormality coefficient, R5 represents the average vibration frequency of the compound fertilizer drying and combustion furnace safety equipment, ΔR5 represents the set reference vibration frequency, and e represents a natural constant.

[0051] It should be added that, in this embodiment, the abnormal operation assessment factor corresponding to the preset normal operation coefficient, the abnormal operation assessment factor corresponding to the sensor abnormality coefficient, the abnormal operation assessment factor corresponding to the communication abnormality coefficient and the abnormal operation assessment factor corresponding to the electrical parameter input abnormality coefficient are obtained from the refractoriness prediction database.

[0052] It needs to be explained that the abnormal operation evaluation factors corresponding to the normal operation coefficient, sensor abnormality coefficient, communication abnormality coefficient and electrical parameter input abnormality coefficient are used to adjust the importance of the normal operation coefficient, sensor abnormality coefficient, communication abnormality coefficient and electrical parameter input abnormality coefficient of the compound fertilizer drying and combustion furnace safety equipment in the process of analyzing and obtaining the abnormal operation evaluation value of the compound fertilizer drying and combustion furnace safety equipment. For example, there is a preset mapping relationship between the operating parameters of the compound fertilizer drying and combustion furnace safety equipment and the corresponding abnormal operation evaluation factors in the refractoriness prediction database. The real-time abnormal operation evaluation factors corresponding to the operating parameters of the compound fertilizer drying and combustion furnace safety equipment can be matched through the preset mapping relationship. The normal operation coefficient, sensor abnormality coefficient, communication abnormality coefficient and electrical parameter input abnormality coefficient of the compound fertilizer drying and combustion furnace safety equipment are matched with the preset mapping relationship respectively to obtain the abnormal operation evaluation factors corresponding to the normal operation coefficient, sensor abnormality coefficient, communication abnormality coefficient and electrical parameter input abnormality coefficient.

[0053] In this implementation scheme, the normal operating coefficient, sensor abnormality coefficient, communication abnormality coefficient, electrical parameter input abnormality coefficient and average vibration frequency of the compound fertilizer drying and combustion furnace safety equipment are correlated and do not exist independently. For example, sensor abnormality usually means that there are errors in data acquisition, which may cause system control failure, thereby affecting the normal operating coefficient. Sensor abnormality may cause incorrect or lost data transmitted on the communication link, thereby increasing the communication abnormality coefficient. Communication abnormality usually causes the control signal to be unable to be transmitted to the execution part of the equipment in a timely manner, thereby affecting the stable operation of the equipment and causing the normal operating coefficient to decrease. Poor communication may cause instability in the electrical parameter input and affect the control system's regulation of the electrical equipment. Comprehensive analysis can obtain the abnormal operation evaluation value of the compound fertilizer drying and combustion furnace safety equipment, which can accurately identify the potential risks and failures of the safety equipment, thereby providing early warning or optimizing maintenance.

[0054] Specifically, the preconfiguration information of the compound fertilizer drying and combustion furnace safety equipment is analyzed and obtained, and the specific analysis process is: the preconfiguration information of the compound fertilizer drying and combustion furnace safety equipment includes executing the safety equipment preconfiguration and not executing the safety equipment preconfiguration.

[0055] The abnormal operation evaluation value of the compound fertilizer drying and combustion furnace safety equipment is compared with the set abnormal operation evaluation threshold. If the abnormal operation evaluation value of the compound fertilizer drying and combustion furnace safety equipment is lower than or equal to the set abnormal operation evaluation threshold, the pre-configuration information of the compound fertilizer drying and combustion furnace safety equipment is marked as not executing safety equipment pre-configuration; otherwise, the pre-configuration information of the compound fertilizer drying and combustion furnace safety equipment is marked as executing safety equipment pre-configuration.

[0056] Specifically, the safety equipment of the compound fertilizer drying and combustion furnace is initialized and modulated. The specific process is: extract the pre-configuration information of the safety equipment of the compound fertilizer drying and combustion furnace. If the pre-configuration information of the safety equipment of the compound fertilizer drying and combustion furnace is not to perform safety equipment pre-configuration, then continue to initialize and modulate the safety equipment of the compound fertilizer drying and combustion furnace with the current safety equipment configuration parameters.

[0057] If the pre-configuration information of the compound fertilizer drying and combustion furnace safety equipment is to execute the safety equipment pre-configuration, the difference between the abnormal operation evaluation value of the compound fertilizer drying and combustion furnace safety equipment and the set abnormal operation evaluation threshold value shall be recorded as the compound fertilizer drying and combustion furnace safety equipment adjustment reference value, and the safety equipment configuration parameters shall be obtained according to the compound fertilizer drying and combustion furnace safety equipment adjustment reference value, and the compound fertilizer drying and combustion furnace safety equipment shall be initialized and modulated based on the safety equipment configuration parameters.

[0058] It should be added that the safety equipment configuration parameters are obtained by matching the safety equipment adjustment reference value of the compound fertilizer drying and combustion furnace, and the safety equipment configuration parameters corresponding to the safety equipment adjustment reference value intervals of each compound fertilizer drying and combustion furnace stored in the refractoriness prediction database are matched, and the safety equipment configuration parameters corresponding to the interval in which the safety equipment adjustment reference value of the compound fertilizer drying and combustion furnace is located are counted and recorded as safety equipment configuration parameters.

[0059] It should be noted that the safety equipment configuration parameters include the speed of the fan and the alarm threshold of the pressure sensor. The analysis of the operating parameters of the compound fertilizer drying and combustion furnace safety equipment can reflect the working quality of the safety equipment. If the working quality of the compound fertilizer drying and combustion furnace safety equipment is unqualified, subsequent monitoring with the original default safety equipment configuration parameters may cause safety equipment failure. Therefore, it is necessary to configure the safety equipment in combination with the safety equipment configuration parameters. The larger the adjustment reference value of the compound fertilizer drying and combustion furnace safety equipment, the more abnormal the safety equipment is, and the smaller the matching fan speed and pressure sensor alarm threshold are.

[0060] Specifically, the fire resistance monitoring stage of the compound fertilizer drying and combustion furnace is monitored, and the specific process is: a number of monitoring areas are set in the inner shell of the compound fertilizer drying and combustion furnace, recorded as each operation monitoring area, and the fire resistance monitoring data of each operation monitoring area of ​​the compound fertilizer drying and combustion furnace is monitored and obtained. The fire resistance monitoring data includes the thermal expansion coefficient, thermal conductivity, inner shell material defect coefficient and number of thermal cycles of each operation monitoring area of ​​the compound fertilizer drying and combustion furnace.

[0061] It should be noted that the thermal expansion coefficient is the degree to which the refractory material inside the combustion furnace expands due to the action of thermal energy when the temperature rises. The ratio of the change in length of the refractory material inside the combustion furnace in the operating monitoring area over a period of time to the initial length is used as the thermal expansion coefficient, which can be measured using a dilatometer to obtain the thermal expansion coefficient. Thermal conductivity is a measure of the thermal conductivity of a material, which refers to the amount of heat transferred by a unit area of ​​material per unit time driven by a temperature difference. A laser thermal conductivity meter can be used to measure the thermal conductivity of the material. The liner material defect coefficient refers to the number of defects (such as cracks, pores, etc.) present in the liner material in the operating monitoring area over a period of time and the de-normalized value. The number of thermal cycles refers to the number of times the liner material in the operating monitoring area experiences alternating high and low temperatures over a period of time. A temperature recorder can be used to record the temperature changes in the furnace in real time to obtain the number of thermal cycles.

[0062] A comprehensive analysis is performed on the fire resistance performance monitoring data of each operating monitoring area of ​​the compound fertilizer drying and combustion furnace to obtain the fire resistance performance index value of the compound fertilizer drying and combustion furnace. The fire resistance performance index value of the compound fertilizer drying and combustion furnace is used to comprehensively quantify the fire resistance of the compound fertilizer drying and combustion furnace in a high temperature environment.

[0063] In this embodiment, the fire resistance index value of the compound fertilizer drying and combustion furnace can be obtained by the following analysis method, and the specific analysis conditions are as follows:

[0064]

[0065] In the formula, k1 represents the fire resistance index value of the compound fertilizer drying and combustion furnace, f i→1 represents the thermal expansion coefficient of the ith operation monitoring area of ​​the compound fertilizer drying and combustion furnace, σ1 represents the fire resistance performance analysis correction factor corresponding to the set thermal expansion coefficient, and f i→2 represents the thermal conductivity of the ith operating monitoring area of ​​the compound fertilizer drying and combustion furnace, Δf i→2 represents the reference thermal conductivity of the set i-th operating monitoring area, f i→3 represents the inner liner material defect coefficient of the i-th operation monitoring area of ​​the compound fertilizer drying and combustion furnace, σ3 represents the fire resistance performance analysis correction factor corresponding to the set inner liner material defect coefficient, and f i→4It represents the number of thermal cycles of the i-th operation monitoring area of ​​the compound fertilizer drying and combustion furnace, σ4 represents the fire resistance performance analysis correction factor corresponding to the set unit number of thermal cycles, i represents the number of each operation monitoring area, i=1,2,3,...,n, n represents the total number of operation monitoring areas, and e represents a natural constant.

[0066] It should be added that, in this embodiment, the fire resistance performance analysis correction factor corresponding to the preset thermal expansion coefficient, the fire resistance performance analysis correction factor corresponding to the liner material defect coefficient and the fire resistance performance analysis correction factor corresponding to the unit thermal cycle number are obtained from the refractoriness prediction database.

[0067] It needs to be explained that the fire resistance analysis correction factors corresponding to the thermal expansion coefficient, the inner liner material defect coefficient and the unit number of thermal cycles are respectively used to adjust the importance of the thermal expansion coefficient, the inner liner material defect coefficient and the number of thermal cycles of each operating monitoring area of ​​the compound fertilizer drying and combustion furnace in the process of analyzing and obtaining the fire resistance index value of the compound fertilizer drying and combustion furnace. For example, there is a pre-set mapping relationship between the fire resistance monitoring data of each operating monitoring area of ​​the compound fertilizer drying and combustion furnace and the corresponding fire resistance analysis correction factors in the refractoriness prediction database. The fire resistance analysis correction factors corresponding to the real-time fire resistance monitoring data of each operating monitoring area of ​​the compound fertilizer drying and combustion furnace can be matched through the pre-set mapping relationship. The thermal expansion coefficient, the inner liner material defect coefficient and the unit number of thermal cycles of each operating monitoring area of ​​the compound fertilizer drying and combustion furnace are matched with the pre-set mapping relationship respectively to obtain the fire resistance analysis correction factors corresponding to the thermal expansion coefficient, the inner liner material defect coefficient and the unit number of thermal cycles.

[0068] In this implementation scheme, the thermal expansion coefficient, thermal conductivity, inner liner material defect coefficient and thermal cycle number of each operating monitoring area of ​​the compound fertilizer drying and combustion furnace are correlated and do not exist independently. For example, when the inner liner material of the furnace body is heated, the thermal expansion coefficient will affect the deformation degree of the inner liner material. Materials with higher thermal conductivity may cause uneven temperature distribution in the furnace, causing overheating in certain areas, thereby increasing the number of thermal cycles. Inner liner materials with higher defect coefficients are more prone to local overheating or rupture. The thermal unevenness caused by defects may increase the deformation caused by thermal expansion, thereby affecting the fire resistance performance. As the number of thermal cycles increases, the microstructure of the inner liner material changes, which may lead to changes in the thermal expansion coefficient, thermal conductivity, defect coefficient, etc., and materials with high thermal conductivity will cause local temperatures to be too high during the thermal cycle. Comprehensive analysis of the fire resistance index value of the compound fertilizer drying and combustion furnace can identify potential defects and inadaptability of the material in advance, so as to take preventive maintenance measures, thereby ensuring the safe and stable operation of the equipment and effectively reducing equipment failures caused by material problems.

[0069] Specifically, the fire resistance performance analysis result of the compound fertilizer drying and combustion furnace is analyzed and obtained, and the specific analysis process is: the fire resistance performance analysis result of the compound fertilizer drying and combustion furnace includes normal fire resistance performance and abnormal fire resistance performance.

[0070] The fire resistance performance index value of the compound fertilizer drying and combustion furnace is compared with the set fire resistance performance index threshold. If the fire resistance performance index value of the compound fertilizer drying and combustion furnace is higher than or equal to the set fire resistance performance index threshold, the fire resistance performance analysis result of the compound fertilizer drying and combustion furnace is marked as normal fire resistance performance; otherwise, the fire resistance performance analysis result of the compound fertilizer drying and combustion furnace is marked as abnormal fire resistance performance.

[0071] Specifically, the high temperature persistence monitoring stage of the compound fertilizer drying and combustion furnace is monitored, and the specific process is: the high temperature persistence monitoring stage of the compound fertilizer drying and combustion furnace is monitored to obtain the high temperature persistence monitoring data of each operation monitoring area of ​​the compound fertilizer drying and combustion furnace, and the high temperature persistence monitoring data of each operation monitoring area of ​​the compound fertilizer drying and combustion furnace includes the high temperature oxidation resistance coefficient of the inner liner material, the average thermal stress value of the inner liner material, the thermal diffusion coefficient and the average temperature value of each operation monitoring area of ​​the compound fertilizer drying and combustion furnace.

[0072] It should be noted that the high-temperature oxidation resistance coefficient of the liner material refers to the ability of the liner material to resist oxidation under high-temperature conditions. The oxide layer thickness value of the liner material in the operation monitoring area can be measured by an oxide layer thickness measuring instrument, and then the absolute value of the difference between the initial oxide layer thickness value and the oxide layer thickness value after a period of time is obtained. The ratio of the obtained absolute value to the initial oxide layer thickness value is recorded as the high-temperature oxidation resistance coefficient of the liner material. The thermal stress of the liner material over a period of time is measured by a strain gauge, and the average value is taken to obtain the average thermal stress value of the liner material. The thermal diffusion coefficient is a quantification of the material's ability to conduct heat, which indicates the rate at which heat propagates in the material. The thermal conductivity of the material is divided by the product of the density of the material and the specific heat capacity of the material, and the value is de-normalized to obtain the thermal diffusion coefficient. The thermal diffusion coefficient can be measured by a laser flash method thermal diffusion instrument. The temperature value over a period of time is measured using a thermocouple, and the average value is taken to obtain the temperature average value.

[0073] Based on the high-temperature persistence monitoring data of each operating monitoring area of ​​the compound fertilizer drying and combustion furnace, combined with the fire resistance performance index value of the compound fertilizer drying and combustion furnace, a comprehensive prediction and evaluation value of the fire resistance performance of the inner liner of the compound fertilizer drying and combustion furnace is obtained. The comprehensive prediction and evaluation value of the fire resistance performance of the inner liner of the compound fertilizer drying and combustion furnace is used to comprehensively quantify the fire resistance durability and reliability of the compound fertilizer drying and combustion furnace in a high temperature environment.

[0074] Specifically, the comprehensive prediction and evaluation value of the fire resistance performance of the inner shell of the compound fertilizer drying and combustion furnace is analyzed under the following specific conditions:

[0075]

[0076] In the formula, β represents the comprehensive prediction and evaluation value of the fire resistance performance of the inner shell of the compound fertilizer drying and combustion furnace, k1 represents the fire resistance performance index value of the compound fertilizer drying and combustion furnace, θ1 represents the comprehensive performance evaluation factor corresponding to the set fire resistance performance index value, and k i→2 represents the high temperature oxidation resistance coefficient of the inner liner material in the i-th operation monitoring area of ​​the compound fertilizer drying and combustion furnace, Δk i→2 represents the high temperature oxidation resistance coefficient of the reference liner material in the set i-th operation monitoring area, k i→3 represents the average value of thermal stress of the liner material in the i-th operation monitoring area of ​​the compound fertilizer drying and combustion furnace, θ3 represents the performance comprehensive evaluation factor corresponding to the set average value of thermal stress of the unit liner material, k i→4 represents the thermal diffusion coefficient of the ith operation monitoring area of ​​the compound fertilizer drying and combustion furnace, Δk i→4 represents the reference thermal diffusion coefficient of the set i-th operation monitoring area, k i→5 represents the average temperature of the ith operating monitoring area of ​​the compound fertilizer drying and combustion furnace, Δk i→5 It represents the reference temperature of the set i-th operation monitoring area, i represents the number of each operation monitoring area, i=1,2,3,...,n, n represents the total number of operation monitoring areas, and e represents a natural constant.

[0077] It should be added that, in this embodiment, the comprehensive performance evaluation factor corresponding to the preset fire resistance performance index value and the comprehensive performance evaluation factor corresponding to the average value of thermal stress of the unit liner material are obtained from the refractoriness prediction database.

[0078] It needs to be explained that the comprehensive performance evaluation factors corresponding to the fire resistance performance index value and the average value of thermal stress per unit liner material are respectively used to adjust the importance of the fire resistance performance index value of the compound fertilizer drying and combustion furnace and the average value of thermal stress of the liner material in each operating monitoring area of ​​the compound fertilizer drying and combustion furnace in the process of analyzing and obtaining the comprehensive prediction evaluation value of the fire resistance performance of the liner. For example, there is a pre-set mapping relationship between the high-temperature persistence monitoring data of each operating monitoring area of ​​the compound fertilizer drying and combustion furnace and the corresponding comprehensive performance evaluation factors in the refractoriness prediction database. The pre-set mapping relationship can be used to match the real-time comprehensive performance evaluation factors corresponding to the high-temperature persistence monitoring data of each operating monitoring area. The fire resistance performance index value of the compound fertilizer drying and combustion furnace and the average value of thermal stress of the liner material in each operating monitoring area of ​​the compound fertilizer drying and combustion furnace are respectively matched with the pre-set mapping relationship to obtain the fire resistance performance index value and the comprehensive performance evaluation factors corresponding to the average value of thermal stress per unit liner material.

[0079] In this implementation scheme, there is a correlation between the refractory performance index value of the compound fertilizer drying and combustion furnace, the high-temperature antioxidant coefficient of the liner material in each operation monitoring area, the average thermal stress of the liner material, the thermal diffusion coefficient and the temperature average value, and they do not exist independently. For example, materials with high antioxidant coefficients can maintain high structural strength and stability at high temperatures, reducing the aging and damage of the liner material of the combustion furnace. Therefore, the high-temperature antioxidant coefficient has a positive effect on the refractory performance of the liner. Materials with strong antioxidant ability are not easily oxidized and damaged in high-temperature environments, thereby effectively reducing the concentration of thermal stress caused by oxidation and avoiding the generation of cracks. A higher thermal diffusion coefficient helps to evenly disperse the temperature and reduce local high temperatures, which can not only reduce the accumulation of thermal stress, but also effectively delay the fatigue damage of the material and enhance the refractory performance. The average temperature directly affects the thermal cycle and aging process of the material. Excessive temperature will aggravate the aging and damage of the material, and appropriate temperature control helps to extend the service life of the liner material and improve the refractory performance. A comprehensive analysis is obtained to obtain a comprehensive prediction and evaluation value of the refractory performance of the liner of the compound fertilizer drying and combustion furnace, providing a durability prediction of the liner material in a high-temperature working environment.

[0080] Specifically, a comprehensive analysis is performed to obtain a comprehensive prediction and evaluation result of the fire resistance performance of the inner liner. The specific analysis process is: extract the fire resistance performance analysis result of the compound fertilizer drying and combustion furnace. If the fire resistance performance analysis result of the compound fertilizer drying and combustion furnace is that the fire resistance performance is abnormal, then the comprehensive prediction and evaluation result of the fire resistance performance of the inner liner is directly marked as unqualified for the comprehensive prediction of the fire resistance performance of the inner liner.

[0081] If the fire resistance performance analysis result of the compound fertilizer drying and combustion furnace is that the fire resistance performance is normal, the comprehensive predicted evaluation value of the fire resistance performance of the inner liner of the compound fertilizer drying and combustion furnace will be compared with the set comprehensive predicted evaluation threshold of the fire resistance performance of the inner liner. If the comprehensive predicted evaluation value of the fire resistance performance of the inner liner of the compound fertilizer drying and combustion furnace is higher than or equal to the set comprehensive predicted evaluation threshold of the fire resistance performance of the inner liner, the comprehensive predicted evaluation result of the fire resistance performance of the inner liner will be marked as qualified; otherwise, the comprehensive predicted evaluation result of the fire resistance performance of the inner liner will be marked as abnormal.

[0082] Specifically, monitoring and early warning configuration is performed, and the specific analysis conditions are: extracting the comprehensive prediction and evaluation results of the inner liner fire resistance performance, if the comprehensive prediction and evaluation results of the inner liner fire resistance performance are that the comprehensive prediction of the inner liner fire resistance performance is qualified, then continue to perform monitoring and configuration with the current inner liner fire resistance performance monitoring configuration parameters.

[0083] If the comprehensive prediction and evaluation result of the inner liner fire resistance performance is that the comprehensive prediction of the inner liner fire resistance performance is abnormal, the current inner liner fire resistance performance monitoring configuration parameters are added to the set inner liner fire resistance performance monitoring configuration parameter supplementary values ​​to obtain the inner liner fire resistance performance monitoring configuration target adjustment parameters, and the inner liner fire resistance performance monitoring configuration parameters are adjusted up to the inner liner fire resistance performance monitoring configuration target adjustment parameters for monitoring configuration.

[0084] It should be noted that the liner fire resistant performance monitoring configuration parameters include the hot air circulation rate and cooling rate of the combustion furnace. The analysis of the operating process of the compound fertilizer drying combustion furnace after initialization modulation can reflect the changes in the fire resistant performance of the liner. If the fire resistant performance of the liner is unqualified, subsequent monitoring with the original default liner fire resistant performance monitoring configuration parameters may lead to inaccurate monitoring results, and may even fail to effectively predict and prevent the decline in the fire resistant performance of the liner. Therefore, it is necessary to combine the liner fire resistant performance monitoring configuration parameters for monitoring and configuration to ensure that the parameters can reflect the fire resistant performance of the liner in real time and accurately, and provide reliable data support for subsequent equipment optimization.

[0085] If the comprehensive prediction and evaluation result of the fire resistance performance of the inner liner is that the comprehensive prediction and evaluation result of the fire resistance performance of the inner liner is abnormal, the comprehensive prediction and evaluation result of the fire resistance performance of the inner liner will be sent to the management terminal for early warning at the same time.

[0086] It should be noted that a method for predicting the refractoriness of a combustion furnace liner for drying compound fertilizers also includes a regional refractoriness prediction database for storing a first parameter set, a second parameter set and a third parameter set obtained by analyzing historical data.

[0087] The first parameter set includes the abnormal operation assessment factor corresponding to the normal operating coefficient, the abnormal operation assessment factor corresponding to the sensor abnormal coefficient, the abnormal operation assessment factor corresponding to the communication abnormal coefficient, the abnormal operation assessment factor corresponding to the electrical parameter input abnormal coefficient, the reference vibration frequency, the abnormal operation assessment threshold and the safety equipment configuration parameters corresponding to the reference value interval for the adjustment of the safety equipment of each compound fertilizer drying and combustion furnace.

[0088] The second parameter set includes the fire resistance performance analysis correction factor corresponding to the thermal expansion coefficient, the reference thermal conductivity of each operation monitoring area, the fire resistance performance analysis correction factor corresponding to the liner material defect coefficient, the fire resistance performance analysis correction factor corresponding to the unit thermal cycle number and the fire resistance performance index threshold.

[0089] The third parameter set includes the comprehensive performance evaluation factor corresponding to the fire resistance performance index value, the high temperature oxidation resistance coefficient of the reference liner material of each operation monitoring area, the comprehensive performance evaluation factor corresponding to the average thermal stress of the unit liner material, the reference thermal diffusion coefficient of each operation monitoring area, the reference temperature of each operation monitoring area, the comprehensive prediction evaluation threshold of the liner fire resistance performance and the supplementary value of the liner fire resistance performance monitoring configuration parameters.
