[0036] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.
[0037] Figure 1 This is a schematic diagram of the cement kiln node parameter correlation verification method provided in the embodiments of this application, as shown below. Figure 1 As shown, it includes:
[0038] Step 110: Obtain the target operating parameters of the cement kiln;
[0039] Specifically, the target operating parameters described in the embodiments of this application can be any operating parameter in the cement kiln growth line, or multiple operating parameters.
[0040] The target operating parameters described in this embodiment can be automatically determined by feedback from historical data of the long-term operation of the control system. Specifically, the central control room of the cement kiln has a DCS control system that can display various monitored parameters online and perform operational control. For example, it can display the temperature at the outlet of the decomposer and the amount of coal used in the decomposer. Operational control can change the amount of coal used in the decomposer by controlling the actuator of the coal scale in the decomposer. The range and frequency of the collected parameters can be automatically determined from the historical data of the DCS system's operation frequency.
[0041] The target operating parameters described in this application embodiment may specifically be the oxygen concentration index, temperature index, nitrogen oxide concentration index, carbon monoxide concentration index, and decomposition furnace outlet temperature index of the kiln tail smoke chamber, or other relevant parameters in the cement kiln production process such as the inlet static pressure index of the high-temperature fan.
[0042] Step 120: Based on the production process of the cement kiln, obtain the associated operating parameters corresponding to the target operating parameters;
[0043] Specifically, the cement kiln production process described in this application refers to each production stage in the cement kiln's dry process for manufacturing cement. Since the various production stages in the cement kiln production process often need to cooperate with each other, this application can determine the associated operating parameters for judging whether there is a parameter deviation based on the logic of the production stages corresponding to each target operating parameter.
[0044] The associated operating parameters described in this application embodiment can be data that affects the target operating parameters, or data that is affected by the target operating parameters.
[0045] Step 130: Determine the data verification range of the target operating parameters based on the associated operating parameters;
[0046] In this embodiment of the application, based on the associated operating parameters and the internal process of cement kiln production, a reasonable range of target operating parameters can be further determined. This reasonable range is the data verification range of the target operating parameters.
[0047] The data verification interval in this embodiment can be used to determine whether the target operating parameter is abnormal data. If the target operating parameter is not covered by the data verification interval, it indicates that the target operating parameter may be abnormal data, which may affect the overall production of the cement kiln.
[0048] If the target operating parameters are covered by the data verification interval, it indicates that the target operating parameters are relatively normal.
[0049] Step 140: If the target operating parameter is not covered by the data verification interval, determine the feedback adjustment scheme corresponding to the associated operating parameter based on the target operating parameter and the associated operating parameter, and adjust the target operating parameter according to the feedback adjustment scheme.
[0050] Specifically, if the target operating parameter is not covered by the data verification interval in this application, it indicates that the target operating parameter is abnormal. In order to ensure that the overall production is not affected by the abnormal target operating parameter, the target operating parameter can be further corrected.
[0051] In this embodiment, many target operating parameters cannot be directly adjusted, and the parameters that can be directly adjusted manually in the production process are limited. In this embodiment, it is necessary to further consider the related operating parameters that can affect the target operating parameters, and in combination with the production process, further determine the feedback adjustment scheme corresponding to the correction of the related operating parameters.
[0052] The feedback adjustment scheme in this application further includes the adjustment objects in each production stage, as well as the specific adjustment strategies.
[0053] In this embodiment of the application, the target operating parameters can be further adjusted through the feedback adjustment scheme. If the adjusted target operating parameters are still not covered by the data verification interval after detection and analysis, it indicates that the adjusted target operating parameters need to be further adjusted until the target operating parameters can be covered by the data verification interval.
[0054] In this embodiment of the application, after obtaining the target operating parameters of the cement kiln, a reasonable operating range of the target operating parameters is further determined based on the associated operating parameters, that is, the data verification range of the target operating parameters is obtained. The target operating parameters are judged to be abnormal through the data verification range, which can effectively identify abnormal target operating parameters. Furthermore, if the target operating parameters are not covered by the data verification range, the abnormality of the target operating parameters is identified, and the target operating parameters are further adjusted through a feedback adjustment scheme, thereby avoiding the abnormal parameters from affecting the overall production process of the cement kiln.
[0055] Optionally, obtaining the associated operating parameters corresponding to the target operating parameters based on the production process of the cement kiln includes:
[0056] When the target operating parameter is the oxygen content parameter of the kiln tail smoke chamber, according to the internal operating logic of the production process, the associated operating parameters corresponding to the oxygen content parameter of the kiln tail smoke chamber are the coal consumption parameter of the kiln head and the carbon monoxide concentration parameter of the kiln tail smoke chamber.
[0057] Alternatively, if the target operating parameter is the kiln tail flue temperature parameter, the associated operating parameters corresponding to the kiln tail flue temperature parameter can be obtained according to the internal operating logic of the production process, namely, the kiln head coal consumption parameter, the kiln tail flue oxygen concentration parameter, the firing zone temperature parameter, and the kiln tail flue carbon monoxide concentration parameter.
[0058] Specifically, in this application embodiment, the target operating parameter to be verified is the oxygen content parameter of the kiln tail smoke chamber. In the production process of cement kiln, the oxygen content of the kiln tail smoke chamber is often related to the combustion status of the kiln tail smoke chamber, and its combustion status is often related to the amount of coal used at the kiln head. At the same time, carbon monoxide and nitrogen oxides in the kiln tail smoke chamber can also effectively reflect its combustion status.
[0059] Therefore, in this embodiment of the application, the parameters related to the coal consumption at the kiln head, the nitrogen oxide concentration in the kiln tail smoke chamber, and the carbon monoxide concentration in the kiln tail smoke chamber, which are associated with the temperature parameters of the kiln tail smoke chamber, can be used to effectively verify whether the oxygen content parameters of the kiln tail smoke chamber are abnormal.
[0060] When the target operating parameter is the temperature parameter of the kiln tail smoke chamber, according to the internal operating logic of the production process, the temperature parameter of the kiln tail smoke chamber is related to the combustion status of the kiln tail smoke chamber, and the temperature parameter of the kiln tail smoke chamber can also be indirectly understood through the temperature of the firing zone.
[0061] Therefore, in this embodiment of the application, the kiln tail smoke chamber temperature parameter is verified by using the associated operating parameters corresponding to the kiln tail smoke chamber temperature parameter as the kiln tail smoke chamber oxygen concentration parameter, the firing zone temperature parameter, and the kiln tail smoke chamber carbon monoxide concentration parameter.
[0062] In some embodiments, the present application can be based on the internal operating logic of the production process.
[0063] In this embodiment of the application, after obtaining the target operating parameters, the internal operating logic of the production process can be further combined to determine the associated operating parameters corresponding to the target operating parameters, and the target operating parameters can be verified based on the associated operating parameters.
[0064] Optionally, obtaining the associated operating parameters corresponding to the target operating parameters based on the production process of the cement kiln includes:
[0065] When the target operating parameter is the static pressure parameter at the inlet of the high-temperature fan, the associated operating parameters corresponding to the static pressure parameter at the inlet of the high-temperature fan are the high-temperature fan speed, the static pressure parameter at the outlet of the preheater, and the static pressure parameter at the outlet of the decomposition furnace.
[0066] Specifically, in the embodiments of this application, if the target operating parameter is the outlet temperature parameter of the decomposition furnace, the relevant parameters associated with its inlet static pressure are often static pressure parameters at other locations in the production process, such as the static pressure at the outlet of the preheater, the speed of the high-temperature fan, and the static pressure at the outlet of the decomposition furnace.
[0067] In this embodiment, the data verification range of the high-temperature fan inlet static pressure parameter can be further determined by the preheater outlet static pressure parameter, the high-temperature fan speed, and the decomposition furnace outlet static pressure parameter, which can effectively verify the abnormality of the decomposition furnace outlet temperature parameter.
[0068] Optionally, determining the feedback adjustment scheme corresponding to the associated operating parameters based on the target operating parameters and the associated operating parameters includes:
[0069] Based on the target operating parameters and the associated operating parameters, determine the abnormal factors of the parameters;
[0070] Based on the abnormal factors of the parameters, a feedback adjustment scheme corresponding to the associated operating parameters is determined.
[0071] Specifically, in this embodiment of the application, after detecting an abnormality in the target operating parameters, it is necessary to further combine the associated operating parameters to determine the factors that caused the parameter abnormality.
[0072] For example, if the target operating parameter is that the oxygen content in the kiln tail flue is lower than each value in its corresponding data verification range, it indicates that the oxygen content in the kiln tail flue is too low. If the coal consumption at the kiln head is greater than 2 / 3 of its normal coal consumption, it means that the coal consumption should not be adjusted, but the corresponding ventilation conditions need to be adjusted.
[0073] At this point, the abnormal parameters may be due to poor ventilation inside the kiln or an excessively large damper in the tertiary air duct, causing combustibles to fall into the smoke chamber.
[0074] In this embodiment of the application, after identifying the abnormal parameter factors, a corresponding feedback adjustment plan is generated based on the internal logic of the production process. This feedback adjustment plan can further resolve the abnormal parameter factors, thereby effectively correcting the target operating parameters.
[0075] Optionally, determining the feedback adjustment scheme corresponding to the associated operating parameters based on the abnormal parameter factors includes:
[0076] When the abnormal factors are abnormal factors in the kiln ventilation or abnormal factors in the coal consumption at the kiln head, the tertiary air damper is adjusted by the actuator according to the preset size.
[0077] If, after N adjustments to the tertiary air damper, the oxygen content parameter of the kiln tail flue is still not covered by the data verification range of the target operating parameter, the coal consumption at the kiln head is adjusted.
[0078] Specifically, in this embodiment, when the abnormal parameter factor is an abnormal factor in kiln ventilation or an abnormal factor in coal consumption at the kiln head, the tertiary air damper is first adjusted by the actuator to reduce it by 5cm at a time. After data feedback, the verification and judgment are continued according to the aforementioned method. If the state is still displayed within 10 minutes, the tertiary air damper is adjusted by the actuator again to reduce it by 5cm at a time.
[0079] After data feedback, continue verification and judgment using the aforementioned method. Repeat the adjustment a maximum of N times. If the status returns to normal, stop feedback control. If the status remains the same, adjust the coal consumption at the kiln head, increasing or decreasing by 0.5 t / h each time. After data feedback, continue verification and judgment using the aforementioned method. If the status remains the same within 10 minutes, continue increasing or decreasing by 0.5 t / h, repeating the adjustment a maximum of 3 times. If the status returns to normal, stop feedback control. If the status remains abnormal, restart the feedback adjustment (tertiary air damper) after 20 minutes. If it fails to return to normal after 2 hours, stop feedback adjustment.
[0080] In this embodiment, by adjusting the tertiary air damper and the coal consumption at the kiln head, the problems of abnormal ventilation or abnormal coal consumption at the kiln head can be solved as a whole, effectively addressing the abnormal target operating parameters caused by abnormal ventilation or abnormal coal consumption at the kiln head.
[0081] Optionally, determining the feedback adjustment scheme corresponding to the associated operating parameters based on the abnormal parameter factors includes:
[0082] If the abnormal parameter is due to data transmission abnormality or instrument accuracy abnormality, activate the backflushing function of the flue gas analyzer.
[0083] Specifically, in the embodiments of this application, if the abnormal parameter factor is a data transmission abnormal factor or an instrument accuracy abnormal factor, it indicates that the target operating parameter may have a large deviation and the target operating parameter has data abnormality.
[0084] At this point, it is necessary to address the issue of inaccurate data detection or low accuracy of the detection instrument. In this embodiment, in the event of abnormal data, the intelligent feedback control system is automatically disconnected, the backflushing cleaning function of the flue gas analyzer is automatically activated, and technical personnel are dispatched to handle the situation on-site. After the above operations, if the situation returns to normal, the intelligent feedback control system is reconnected. If the situation does not return to normal, the disconnected state is maintained until the situation is restored and the data is normal.
[0085] In this embodiment of the application, when the abnormal parameter factor is an abnormal instrument accuracy factor, the backflush function of the delay analyzer can effectively solve the problem of abnormal target operating parameters caused by abnormal instrument accuracy.
[0086] In some embodiments of this application, the collection of target operating parameters is timed. Data is collected and obtained at certain intervals, and the obtained data is used for correlation judgment in real time. The correlation model is determined when it is established and written to the software backend. The logic judgment of correlation verification can be modified and adjusted for different working conditions and different enterprises. Every adjustment to the logic judgment term or threshold of correlation verification must be logged.
[0087] In some embodiments, after detecting an abnormality in the target operating parameter, this application embodiment may only need to further determine the error range of the target operating parameter. If the target operating parameter has a continuous error and the amount of error has a certain pattern, a correction coefficient can be set, and then the corrected data can be output.
[0088] If the deviations of the collected target operating parameters are irregular and mostly sudden or abrupt, it indicates that there is no pattern to them. In this case, it is recommended to remove the abnormal target operating parameters.

The cement kiln node parameter correlation verification device described below and the cement kiln node parameter correlation verification method described above can be referred to in correspondence with each other.

[0091] Optionally, the device is further used for:
[0092] When the target operating parameter is the oxygen content parameter of the kiln tail flue, according to the internal operating logic of the production process, the associated operating parameters corresponding to the oxygen content parameter of the kiln tail flue are obtained as the coal consumption parameter at the kiln head, the nitrogen oxide concentration parameter of the kiln tail flue, and the carbon monoxide concentration parameter of the kiln tail flue.
[0093] Alternatively, if the target operating parameter is the kiln tail smoke chamber temperature parameter, according to the internal operating logic of the production process, the associated operating parameters corresponding to the kiln tail smoke chamber temperature parameter are obtained as the kiln tail smoke chamber oxygen concentration parameter, the firing zone temperature parameter, and the kiln tail smoke chamber carbon monoxide concentration parameter.

[0102] Optionally, the device is further used for:
[0103] If the abnormal parameter is a factor affecting instrument accuracy, activate the backflush function of the flue gas analyzer.
[0104] In this embodiment of the application, after obtaining the target operating parameters of the cement kiln, a reasonable operating range of the target operating parameters is further determined based on the associated operating parameters, that is, the data verification range of the target operating parameters is obtained. The target operating parameters are judged to be abnormal through the data verification range, which can effectively identify abnormal target operating parameters. Furthermore, if the target operating parameters are not covered by the data verification range, the abnormality of the target operating parameters is identified, and the target operating parameters are further adjusted through a feedback adjustment scheme, thereby avoiding the abnormal parameters from affecting the overall production process of the cement kiln.
