Description

Technical Field

[0001] This invention belongs to the field of flue gas monitoring technology, and particularly relates to a flue gas monitoring and analysis method and a monitoring sensor. Background Technology

[0002] In order to achieve the monitoring, analysis and processing of flue gas and thus improve the reliability of monitoring and analysis of pollutants in flue gas, the existing technical solutions in the flue gas monitoring and processing of thermal power plants often rely on multi-channel acquisition systems for pollutant detection and analysis. A similar technical solution is given in the invention patent application CN202210460815.2 "A hybrid sampling measurement structure with built-in ash removal function and its working method".

[0003] However, the above technical solutions neglect the determination of a collaborative monitoring scheme for flue gas from different channels. In actual testing, due to the large amount of dust in the flue gas, if multiple flue gas monitoring devices are used for simultaneous monitoring and processing, it will inevitably lead to a risk of contamination for the sensors of all multiple flue gas monitoring devices. Therefore, how to achieve collaborative monitoring and processing of sensors from multiple flue gas monitoring devices to improve the reliability of flue gas monitoring and analysis has become an urgent technical problem to be solved.

[0004] To address the aforementioned technical problems, this application provides a flue gas monitoring and analysis method and a monitoring sensor. Summary of the Invention

[0005] To achieve the objectives of this invention, the following technical solution is adopted:

[0006] Specifically, this application provides a flue gas monitoring and analysis method, which includes:

[0007] S1 uses the monitoring data of the flue gas monitoring equipment as a basis to determine the consistency of the monitoring data of the flue gas monitoring equipment within the ash content range. Based on the consistency, it determines the consistent monitoring equipment in each ash content range. According to the distribution of the consistent monitoring equipment in each ash content range, it determines that when verification analysis can be performed, the flue gas monitoring equipment is divided into verification equipment and monitoring equipment based on the distribution.

[0008] S2 uses the consistent monitoring equipment and ash content of the monitoring equipment within the ash content range to determine the verification processing plan for the verification equipment in different ash content ranges. Using the verification processing plan and the monitoring data of the monitoring equipment in each ash content range, the management method for the target operating range of the verification equipment is determined.

[0009] The beneficial effects of this invention are as follows:

[0010] By using consistent monitoring equipment and ash content within the ash content range, a verification processing scheme for the verification equipment in different ash content ranges is determined. This ensures the reliability of verification processing in ash content ranges with a small number of consistent monitoring equipment and low ash content. At the same time, by combining ash content, the impact of frequent verification processing in ash content ranges with high ash content on the verification accuracy of the verification equipment is avoided, thus improving the reliability of verification processing.

[0011] By utilizing the verification processing scheme and monitoring data from monitoring devices within each ash content range, a management method for determining the target operating range of the verification devices is established. This avoids the technical problem of poor reliability in verification processing within ash content ranges where there are many consistent monitoring devices or where the ash content is high, due to the lack of verification processing. Furthermore, by combining monitoring data, the monitoring reliability of monitoring devices belonging to consistent monitoring devices within the aforementioned ash content ranges is determined for other ash content ranges. In ash content ranges with higher monitoring reliability, the verification devices are controlled for operation, thereby achieving reliable verification processing for monitoring devices belonging to consistent monitoring devices within the aforementioned ash content ranges.

[0012] Furthermore, the monitoring data of the flue gas monitoring equipment includes monitoring data from different flue gas monitoring equipment, which is specifically determined by reading the results from the background database.

[0013] Furthermore, the ash content range is divided based on historical monitoring data of the ash content of the flue gas. On the basis of one possible approach, the historical monitoring data is divided into a preset number of ash content ranges at equal intervals.

[0014] Furthermore, the consistency of the monitoring data of the flue gas monitoring equipment is determined based on the consistency of the monitoring data of different flue gas monitoring equipment. Specifically, the consistency is determined based on the time when the monitoring data of different flue gas monitoring equipment meets the monitoring error rate range.

[0015] Furthermore, the method for determining the consistent monitoring device within the ash content range is as follows:

[0016] Using the consistent monitoring time data of the flue gas monitoring device within the ash content range and other flue gas monitoring devices, the distribution data of the consistent monitoring time in the monitoring time is determined;

[0017] Based on the distribution data, it is determined whether the flue gas monitoring device is a consistent monitoring device.

[0018] Furthermore, the method for determining the management method of the operating target range of the verification equipment is as follows:

[0019] Based on the verification and processing scheme, the ash content range that does not require verification processing of the monitoring equipment is determined and is regarded as the unverified range;

[0020] Based on the monitoring data of the monitoring equipment in the unverified interval, identify the consistent monitoring equipment among the monitoring equipment in the unverified interval and use it as the verification target equipment;

[0021] Based on the monitoring data of the target equipment in each ash content range, the ash content range of the target equipment is determined to be the range of consistent monitoring equipment. Based on the verification processing scheme of the target equipment belonging to the ash content range of consistent monitoring equipment, the management method of the target operating range of the verification equipment is determined.

[0022] Secondly, the present invention provides a monitoring sensor installed in a flue gas monitoring device and applied to the above-mentioned flue gas monitoring and analysis method, specifically including: monitoring and analyzing the content of pollutants.

[0023] Other features and advantages will be set forth in the following description, and the objects and other advantages of the invention are realized and obtained through the structures particularly pointed out in the description and the drawings.

[0029] To enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this specification, and not all embodiments. Based on the embodiments of this specification, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this specification.

[0030] Example 1

[0031] like Figure 1 As shown, this application provides a flue gas monitoring and analysis method, specifically including:

[0032] S1 uses the monitoring data of the flue gas monitoring equipment as a basis to determine the consistency of the monitoring data of the flue gas monitoring equipment within the ash content range. Based on the consistency, it determines the consistent monitoring equipment in each ash content range. According to the distribution of the consistent monitoring equipment in each ash content range, it determines that when verification analysis can be performed, the flue gas monitoring equipment is divided into verification equipment and monitoring equipment based on the distribution.

[0033] Furthermore, the monitoring data of the flue gas monitoring equipment includes monitoring data from different flue gas monitoring equipment, which is specifically determined by reading the results from the background database.

[0034] It should be noted that the monitoring data includes SO2, NOx, and CO / CO2.

[0035] Furthermore, the ash content range is divided based on historical monitoring data of the ash content of the flue gas. On the basis of one possible approach, the historical monitoring data is divided into a preset number of ash content ranges at equal intervals.

[0036] In one possible embodiment, the preset quantity is 10.

[0037] Furthermore, the consistency of the monitoring data of the flue gas monitoring equipment is determined based on the consistency of the monitoring data of different flue gas monitoring equipment. Specifically, the consistency is determined based on the time when the monitoring data of different flue gas monitoring equipment meets the monitoring error rate range.

[0038] It is understood that the monitoring error rate is determined based on the factory data of the flue gas monitoring equipment. When the deviation rate between the monitoring data of different flue gas monitoring equipment at the specified time is less than the monitoring error rate, the flue gas monitoring equipment at the specified time is determined to be a consistent monitoring time.

[0039] The specific deviation rate is determined based on the ratio of the absolute value of the deviation of the monitoring data of different flue gas monitoring devices at that time to the minimum value of the monitoring data of different flue gas monitoring devices at that time.

[0040] Specifically, such as Figure 2 As shown, the method for determining the consistent monitoring device within the ash content range is as follows:

[0041] Using the consistent monitoring time data of the flue gas monitoring device within the ash content range and other flue gas monitoring devices, the distribution data of the consistent monitoring time in the monitoring time is determined;

[0042] Based on the distribution data, it is determined whether the flue gas monitoring device is a consistent monitoring device.

[0043] It is understood that when the average interval between adjacent consistent monitoring times of the flue gas monitoring device and other flue gas monitoring devices meets the requirements, the flue gas monitoring device is determined to be a consistent monitoring device with other flue gas monitoring devices.

[0044] In one possible embodiment, when the average interval between adjacent consistent monitoring times of the flue gas monitoring device and other flue gas monitoring devices is less than 1 minute, the flue gas monitoring device is determined to be a consistent monitoring device with other flue gas monitoring devices.

[0045] Furthermore, it was determined that verification analysis could be performed, specifically including:

[0046] Distribution of consistent monitoring equipment for flue gas within various ash content ranges

[0047] Based on the distribution of consistent monitoring equipment in various ash content ranges, the flue gas monitoring equipment that is consistent monitoring equipment in all ash content ranges is identified.

[0048] By using flue gas monitoring equipment data that belongs to the same monitoring equipment across all ash content ranges, it can be determined whether verification analysis can be performed.

[0049] It is understandable that when the number of flue gas monitoring devices that are consistent monitoring devices in all ash content ranges meets the requirements, that is, when there are at least two, even if one of the flue gas monitoring devices that are consistent monitoring devices in all ash content ranges is no longer used as a verification device, the reliability of flue gas monitoring and processing can still be guaranteed. Therefore, it is determined that verification analysis and processing can be carried out.

[0050] Furthermore, flue gas monitoring equipment is divided into verification equipment and monitoring equipment, specifically including:

[0051] Flue gas monitoring equipment that is consistent across all ash content ranges will be considered as alternative verification equipment.

[0052] The verification equipment among the candidate verification equipment is determined based on the consistent monitoring time data of the candidate verification equipment in each ash content range.

[0053] It is understood that the verification device is the candidate verification device with the smallest average average interval duration of adjacent consistent monitoring times within each ash content range.

[0054] S2 uses the consistent monitoring equipment and ash content of the monitoring equipment within the ash content range to determine the verification processing plan for the verification equipment in different ash content ranges. Using the verification processing plan and the monitoring data of the monitoring equipment in each ash content range, the management method for the target operating range of the verification equipment is determined.

[0055] Specifically, such as Figure 3 As shown, the method for determining the verification processing scheme of the verification equipment within the ash content range is as follows:

[0056] Based on the consistent monitoring data of the monitoring equipment within the ash content range, the number of consistent monitoring equipment within the ash content range is determined;

[0057] Based on the ash content range, determine the maximum value at the endpoint of the ash content range and use it as the ash content;

[0058] The average number of consistent monitoring devices in each ash content range is determined by using the number of consistent monitoring devices in the monitoring equipment within the ash content range. The verification processing scheme of the verification device in each ash content range is then determined using the average number and the ash content.

[0059] It is understandable that when the average number of consistent monitoring devices in each ash content range meets the requirements, i.e., not less than 2, then the verification of the monitoring devices only needs to be carried out using the verification device in accordance with the preset strategy within the ash content range where the ash content meets the requirements.

[0060] Furthermore, if the average number of consistent monitoring devices in each ash content range does not meet the requirements, then if the ash content in the ash content range meets the requirements, the monitoring devices will be verified according to a preset strategy.

[0061] Additionally, it can be understood that if the ash content within the ash content range does not meet the requirements, then if the number of consistent monitoring devices among the monitoring devices within the ash content range meets the requirements, it is determined that the verification of the monitoring devices does not need to be performed using verification devices within the ash content range. However, if the number of consistent monitoring devices among the monitoring devices within the ash content range does not meet the requirements, then the verification of the monitoring devices is performed using verification devices according to the second preset strategy within the ash content range.

[0062] Specifically, the method for determining the management method of the operating target range of the verification equipment is as follows:

[0063] Based on the verification and processing scheme, the ash content range that does not require verification processing of the monitoring equipment is determined and is regarded as the unverified range;

[0064] Based on the monitoring data of the monitoring equipment in the unverified interval, identify the consistent monitoring equipment among the monitoring equipment in the unverified interval and use it as the verification target equipment;

[0065] Based on the monitoring data of the target equipment for verification in each ash content range, the number of ash content ranges of the target equipment for verification belonging to the consistent monitoring equipment and the verification processing scheme are determined, and the management method of the target operating range of the verification equipment is determined.

[0066] It is understandable that if all the verification target devices belong to the ash content range of the preset strategy of the consistent monitoring device, then the ash content of the ash content range is used to determine the operating target range. That is, the ash content range in which all the verification target devices with the smallest ash content belong to the consistent monitoring device and are verified using the preset strategy is taken as the operating target range, and the verification device is controlled to operate within the operating target range.

[0067] Additionally, it should be noted that when not all verification target devices belong to the ash content range of the preset strategy for consistent monitoring devices, the ash content ranges of the preset strategy for consistent monitoring devices to which the verification target devices belong are freely combined to construct monitoring combinations. With the goal of all verification target devices in the monitoring combination belonging to consistent monitoring devices, candidate monitoring combinations are determined. That is, in the ash content ranges of the candidate monitoring combinations, the verification target devices belong to consistent monitoring devices in at least one ash content range. The maximum ash content and the number of ash content ranges in the candidate monitoring combinations are used to determine the target operating range, and the verification devices are controlled to operate within the target operating range.

[0068] Example 2

[0069] Secondly, the present invention provides a monitoring sensor installed in a flue gas monitoring device and applied to the above-mentioned flue gas monitoring and analysis method, specifically including: monitoring and analyzing the content of pollutants.

[0070] Optionally, the method for determining the consistent monitoring device within the ash content range is as follows:

[0071] Using the consistent monitoring time data of the flue gas monitoring device within the ash content range and other flue gas monitoring devices, the distribution data of the consistent monitoring time in the monitoring time is determined;

[0072] Based on the distribution data, determine the maximum value of the interval between adjacent consistent inspection times of the flue gas monitoring device and other flue gas monitoring devices;

[0073] The flue gas monitoring device is determined as a consistent monitoring device based on the maximum value of the interval duration.

[0074] It should be noted that when the maximum value of the interval duration is not greater than the preset interval duration threshold, the flue gas monitoring device is determined to be a consistent monitoring device with other flue gas monitoring devices.

[0075] Example 3

[0076] Furthermore, the method for determining the verification processing scheme of the verification equipment within the ash content range is as follows:

[0077] Based on the consistent monitoring data of the monitoring equipment within the ash content range, the number of consistent monitoring equipment within the ash content range is determined;

[0078] Based on the ash content range, determine the maximum value at the endpoint of the ash content range and use it as the ash content;

[0079] By using the number of consistent monitoring devices and the ash content among the monitoring devices within the ash content range, the verification processing scheme of the verification device within the ash content range is determined.

[0080] It should be noted that when the number of consistent monitoring devices in the monitoring equipment within the ash content range meets the requirements, it is determined that the accuracy of the monitoring and processing of flue gas data within the ash content range is relatively high. Therefore, it is determined that no verification processing of the monitoring equipment is required within the ash content range.

[0081] In one possible specific embodiment, when there are at least two consistent monitoring devices among the monitoring devices in the ash content range, it is determined that the verification of the monitoring devices does not need to be performed using verification devices in the ash content range.

[0082] It is understandable that when the number of consistent monitoring devices in the ash content range does not meet the requirements, it is also necessary to determine the ash content in the ash content range. When the ash content meets the requirements, the verification process in the ash content range will not affect the sensor of the verification device. Therefore, it is determined that the verification process of the monitoring device will be carried out in the ash content range according to the preset strategy.

[0083] In one possible embodiment, when the ash content within the ash content range is not greater than 10%, the verification process of the monitoring device is determined to be performed within the ash content range according to a preset strategy.

[0084] Additionally, it should be noted that when the ash content within a certain ash content range does not meet the requirements, it is necessary to determine the number of ash content ranges that do not require monitoring and the number of ash content ranges that do require monitoring. If both the number of ash content ranges that do not require monitoring and the number of ash content ranges that require monitoring meet the requirements, then it is determined that the monitoring equipment does not need to be verified within the ash content range.

[0085] In one possible embodiment, when the number of ash content ranges that do not require monitoring is no more than one and the number of ash content ranges other than the ash content ranges that do not require monitoring and the ash content ranges that require monitoring is no more than two, then even if no verification processing is performed in the remaining ash content ranges, the reliability of the verification processing can still be guaranteed. Therefore, it is determined that no verification processing of the monitoring device is required within the ash content range.

[0086] Furthermore, when both the number of ash content ranges that do not require monitoring and the number of ash content ranges that require monitoring meet the requirements, the remaining number of ash content ranges excluding those that do not require monitoring and those that require monitoring is taken as the remaining monitoring quantity. Based on the number of ash content ranges that do not require monitoring and the remaining monitoring quantity, an ash content threshold is determined. When the ash content of the ash content range is less than the ash content threshold, it is determined that the verification processing of the monitoring equipment is performed within the ash content range according to the second preset strategy. When the ash content of the ash content range is not less than the ash content threshold, it is determined that the verification processing of the monitoring equipment is not required within the ash content range.

[0087] In one possible embodiment, the ash content threshold is determined based on the number of ash content intervals that do not require monitoring and the remaining monitoring quantity. In another possible embodiment, the number of monitoring deviations is determined based on the sum of the number of ash content intervals that do not require monitoring and the remaining monitoring quantity. The ratio of the number of monitoring deviations to the total number of ash content intervals is used to determine the monitoring deviation ratio. The sum of the monitoring deviation ratio and 1 is used as a correction ratio factor. The product of the preset ash content and the correction ratio factor is used as the ash content threshold.

[0088] In one possible specific embodiment, the preset ash content is 20%.

[0089] In another possible embodiment, based on the number of ash content intervals that do not require monitoring and the remaining number of monitoring, a mathematical model based on the analytic hierarchy process is constructed to determine the ash content threshold. The more ash content intervals that do not require monitoring and the more remaining monitoring, the larger the ash content threshold.

[0090] It should be noted that the preset strategy is to activate the verification device for a preset duration within the ash content range according to a preset time period to obtain monitoring data, and then use the monitoring data to verify the monitoring data of the monitoring device.

[0091] In one possible embodiment, the preset time period can be 1 day, and the preset duration can be 10 minutes.

[0092] Furthermore, the second preset strategy is to activate the verification device for a preset duration within the ash content range to obtain monitoring data when the number of consistent monitoring times within the most recent preset time period in the ash content range does not meet the requirements, and then use the monitoring data to verify the monitoring data of the monitoring device.

[0093] In one possible embodiment, when the number of consistent monitoring moments within the ash content range is greater than 20 within the most recent hour, the verification device is activated for a preset duration within the ash content range to obtain monitoring data, and the monitoring data is used to verify the monitoring data of the monitoring device.

[0094] Example 4

[0095] Furthermore, the method for determining the management method of the operating target range of the verification equipment is as follows:

[0096] Based on the verification and processing scheme, the ash content range that does not require verification processing of the monitoring equipment is determined and is regarded as the unverified range;

[0097] Based on the monitoring data of the monitoring equipment in the unverified interval, identify the consistent monitoring equipment among the monitoring equipment in the unverified interval and use it as the verification target equipment;

[0098] Based on the monitoring data of the target equipment in each ash content range, the ash content range of the target equipment is determined to be the range of consistent monitoring equipment. Based on the verification processing scheme of the target equipment belonging to the ash content range of consistent monitoring equipment, the management method of the target operating range of the verification equipment is determined.

[0099] It is understandable that when there are verification target devices that do not belong to the consistency monitoring device within the ash content range of the verification processing scheme as a preset strategy, even if the verification processing scheme is operated within the ash content range of the preset strategy, the verification processing result of the verification target device may not meet the requirements. Therefore, based on this, the ash content range of the verification target device belonging to the consistency monitoring device as the operating target range is taken as the operating target range, and the verification device is controlled to operate within the operating target range.

[0100] Additionally, it should be noted that when there are no verification target devices within the ash content range of the preset strategy in the verification processing scheme, and none of them belong to the verification target devices of the consistency monitoring device, it is also necessary to determine whether the number of unverified ranges meets the requirements. If the number of unverified ranges does not meet the requirements, then because the number of unverified ranges is large, in order to ensure the reliability of the verification processing, the ash content range of the verification target devices belonging to the preset strategy of the consistency monitoring device is taken as the operating target range, and the verification device is controlled to operate within the operating target range.

[0101] In one possible embodiment, if the number of unverified intervals is not less than 3, then it is determined that the number of unverified intervals does not meet the requirement.

[0102] Furthermore, when the number of unverified intervals meets the requirements, it is also necessary to determine the total number of verification target devices. If the total number of verification target devices does not meet the requirements, then for the reliability of the verification process, the ash content interval of the verification target devices belonging to the preset strategy of the consistent monitoring devices is taken as the operating target interval, and the verification devices are controlled to operate within the operating target interval.

[0103] In one possible embodiment, if the total number of the verification target devices is not less than 3, then it is determined that the total number of the verification target devices does not meet the requirement.

[0104] Furthermore, if the total number of the verification target devices meets the requirements, and if all the verification target devices belong to the ash content range of the preset strategy of the consistent monitoring device, then the ash content of the ash content range is used to determine the operating target range. That is, the ash content range in which all the verification target devices with the smallest ash content belong to the consistent monitoring device and are verified using the preset strategy is taken as the operating target range, and the verification device is controlled to operate within the operating target range.

[0105] Additionally, it should be noted that when not all verification target devices belong to the ash content range of the preset strategy for consistent monitoring devices, the ash content ranges of the preset strategy for consistent monitoring devices to which the verification target devices belong are freely combined to construct monitoring combinations. With the goal of all verification target devices in the monitoring combination belonging to consistent monitoring devices, candidate monitoring combinations are determined. That is, in the ash content ranges of the candidate monitoring combinations, the verification target devices belong to consistent monitoring devices in at least one ash content range. The maximum ash content and the number of ash content ranges in the candidate monitoring combinations are used to determine the target operating range, and the verification devices are controlled to operate within the target operating range.

[0106] It should be noted that the target operating range is determined by using the maximum ash content and the number of ash content ranges in the candidate monitoring combinations, specifically including:

[0107] The candidate monitoring combination with the smallest maximum ash content is selected as the target operating range. If there are multiple candidate monitoring combinations with the smallest maximum ash content, the ash content range of the candidate monitoring combination with the smallest number of ash content ranges among the candidate monitoring combinations with the smallest maximum ash content is selected as the target operating range.

[0108] It is understood that controlling the verification equipment to operate within the target operating range specifically includes:

[0109] The verification equipment is allowed to operate normally within the target operating range, thereby enabling accurate determination of the operating status of the target verification equipment.
