Description

Technical Field

[0001] This application relates to the technical field of cooling tower control, and in particular to a method and system for monitoring the operation of indirect air-cooled towers. Background Technology

[0002] Indirect air-cooled towers, as a highly efficient and water-saving cooling device, have been widely used in areas with relatively scarce water resources. However, the generally strong winds in these areas during winter pose a serious challenge to the stable and efficient operation of indirect air-cooled towers.

[0003] When ambient wind flows through an indirect air-cooled tower, it creates complex airflow field changes at different locations around the tower due to the tower's structure and wind direction. These changes lead to significant differences in the air intake conditions and heat dissipation efficiency of each cooling triangular unit, resulting in uneven distribution of the outlet water temperature around the tower. This "thermal inhomogeneity" not only reduces the overall cooling efficiency of the air-cooled tower but can also, in severe cases, trigger localized freezing risks, threatening the safe operation of the unit. Current macroscopic monitoring methods cannot capture the dynamic characteristics of the uneven microscopic thermal distribution within the tower caused by ambient wind, making it impossible to formulate effective windproofing and wind-resistance optimization measures due to a lack of precise data support and theoretical basis.

[0004] Therefore, there is an urgent need for a solution that can reveal the inherent influence of the "thermal non-uniformity" phenomenon, so as to provide technical means to fundamentally improve the operating performance of air-cooled towers in strong wind environments. Summary of the Invention

[0005] This application proposes a method and system for monitoring the operation of indirect air-cooled towers to address the deficiencies of the prior art.

[0006] According to a first aspect of the embodiments of this application, a method for monitoring the operation of an indirect air-cooled tower is provided, wherein the heat dissipation circumference of the indirect air-cooled tower body includes a plurality of independent cooling triangular units distributed along the circumference of the indirect air-cooled tower, the method comprising: During the operation of the indirect air-cooled tower, based on the unified clock reference provided by the data acquisition device according to the preset acquisition cycle, the set of operating parameters reflecting the overall operating status of the indirect air-cooled tower, the set of environmental meteorological parameters including at least the ambient wind speed and the ambient wind direction, and the independent outlet water temperature data of each cooling triangular unit are collected synchronously. The collected environmental meteorological parameter set, the operating parameter set, and the independent outlet water temperature data of each cooling triangular unit are transmitted to the data processing center in real time. The data processing center generates a unique timestamp for each collection cycle, and integrates the environmental meteorological parameter set, the operating parameter set, and the independent outlet water temperature data of each cooling triangular unit under the same timestamp to construct a comprehensive analysis dataset. Each data record in the comprehensive analysis dataset includes a timestamp, the environmental meteorological parameter set, the operating parameter set, and multiple independent outlet water temperatures indexed by the cooling triangular unit number. Under different environmental wind conditions and different operating conditions, the analysis based on the comprehensive analysis dataset is used to analyze the non-uniform variation of the outlet water temperature of each cooling triangular unit in the circumferential direction of the indirect air-cooled tower.

[0007] In some implementations, the set of operating parameters includes the inlet water temperature of the radiator inlet header, the outlet water temperature of the radiator return header, and the circulating water flow rate of the circulating water header. The set of environmental meteorological parameters includes environmental wind speed, environmental wind direction, environmental dry-bulb temperature, environmental relative humidity, and environmental atmospheric pressure. The independent outlet water temperature data of each cooling triangle unit is obtained by measuring the temperature at a temperature measuring point set on the outlet water pipe of each cooling triangle of the indirect air-cooled tower. The independent outlet water temperature data of each cooling triangle unit is the spatial distribution data of the circumferential outlet water temperature of the indirect air-cooled tower.

[0008] In some embodiments, the plurality of independent cooling triangular units are uniformly distributed circumferentially around the perimeter of the indirect air-cooled tower, and independent outlet water temperature data of each cooling triangular unit are collected, including: Two thermometers are installed on the water outlet pipe of each cooling triangle unit; Read the measured values ​​of the two thermometers and calculate the average value, and use the average value as the outlet water temperature data of the current cooling triangular unit.

[0009] In some implementations, each thermometer has a resolution of no more than 0.2°C and an accuracy of no less than 0.5%.

[0010] In some implementations, the simultaneous acquisition of the environmental meteorological parameter set, which includes at least ambient wind speed and ambient wind direction, includes: Environmental meteorological parameters are collected at a preset distance upwind of the indirect air-cooled tower, wherein the preset distance is 30 to 50 meters away from the indirect air-cooled tower and the collection height is 1.5 meters above the ground. The ambient wind speed and direction are collected using an anemometer with an accuracy of not less than ±0.1 m / s and a wind direction meter with an accuracy of not less than ±1°.

[0011] In some implementations, collecting the set of operating parameters includes: The inlet water temperature of the radiator inlet header and the outlet water temperature of the radiator return header are collected using a platinum resistance thermometer. The resolution of the platinum resistance thermometer is not greater than 0.2℃ and the accuracy of the platinum resistance thermometer is not less than 0.5 grade. Select a straight pipe section on the circulating water main pipe with a length greater than 15 times the pipe diameter, and install an ultrasonic flow meter on the straight pipe section. The installation position of the ultrasonic flow meter is not less than 10 times the pipe diameter from the upstream disturbance component and not less than 5 times the pipe diameter from the downstream disturbance component. The circulating water flow rate of the circulating water main pipe is collected based on the ultrasonic flow meter.

[0012] In some implementations, the data acquisition device is a data acquisition card, which provides a unified clock reference and synchronously acquires, converts, and integrates the signals output by each sensor before sending them to the data processing center.

[0013] In some implementations, the data processing center is an industrial control computer.

[0014] In some embodiments, the method further includes: Based on the comprehensive analysis dataset, a distribution cloud map or analysis report is generated to reflect the circumferential outlet water temperature of the cooling tower under specific environmental wind conditions. The distribution cloud map or analysis report is used to guide the wind resistance optimization of the indirect air-cooled tower.

[0015] According to a second aspect of this application, an operation monitoring system for an indirect air-cooled tower is provided, wherein the heat dissipation circumference of the indirect air-cooled tower body includes multiple independent cooling triangular units distributed circumferentially along the indirect air-cooled tower, and the system includes: The data acquisition module is used to synchronously acquire, during the operation of the indirect air-cooled tower, a set of operating parameters reflecting the overall operating status of the indirect air-cooled tower, an environmental meteorological parameter set including at least ambient wind speed and ambient wind direction, and independent outlet water temperature data of each cooling triangular unit, based on a unified clock reference provided by the data acquisition device according to a preset acquisition cycle. The data transmission module is used to transmit the collected environmental meteorological parameter set, the operating parameter set, and the independent outlet water temperature data of each cooling triangular unit to the data processing center in real time. The comprehensive analysis dataset construction module is used by the data processing center to generate a unique timestamp for each collection period, and to associate and integrate the environmental meteorological parameter set, the operating parameter set, and the independent outlet water temperature data of each cooling triangular unit under the same timestamp to construct a comprehensive analysis dataset. Each data record in the comprehensive analysis dataset includes a timestamp, the environmental meteorological parameter set, the operating parameter set, and multiple independent outlet water temperatures indexed by the cooling triangular unit number. The water outlet status analysis module is used to analyze the uneven variation of water temperature at the outlet of each cooling triangular unit in the circumference of the indirect air-cooled tower under different environmental wind conditions and different operating conditions, based on the comprehensive analysis dataset.

[0016] The beneficial effects of the indirect air-cooled tower operation monitoring method and system of this application embodiments include at least: This application first synchronously collects a multi-dimensional parameter set based on a unified clock reference, ensuring strict temporal synchronization and comparability of operating parameters reflecting the overall tower status, environmental wind parameters affecting tower operation, and water temperatures of each triangular unit reflecting the local state of the tower. This lays a solid foundation for establishing accurate correlations later. Secondly, the above three types of data are transmitted to the data processing center in real time, ensuring the effective aggregation of massive amounts of monitoring data in terms of immediacy and completeness. This avoids analytical distortion caused by data transmission delays or losses, providing a guarantee for constructing a continuous and reliable analytical dataset. Next, the three types of data are correlated and integrated using timestamps to construct a comprehensive analytical dataset with a specific structure. This allows the tower's operating conditions, external environmental excitations, and internal circumferential temperature distribution response at each moment to be completely encapsulated in a single data record, greatly enhancing the inherent correlation of the data and the convenience of analysis. Finally, based on this dataset, the temperature non-uniformity variation pattern under different wind and operating conditions can be analyzed. This allows the influence of environmental wind to be separated from the complex operating state, revealing the key wind field characteristics and dynamic mechanisms leading to uneven heat dissipation. This provides a direct and scientific decision-making basis for implementing precise and efficient wind protection optimization measures. Attached Figure Description

Figure 2 This is a schematic diagram of the operation monitoring system for an indirect air-cooled tower according to an embodiment of this application. Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the operation monitoring method and system for indirect air-cooled towers will be described clearly and completely below in conjunction with the accompanying drawings of the embodiments of this application. Obviously, the described embodiments are only some embodiments of the embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed embodiments of the present application, but merely to illustrate selected embodiments of the present application. Other embodiments obtained by those skilled in the art based on the embodiments of the present application without inventive effort are all within the scope of protection of the embodiments of the present application.

[0020] It can be noted that similar reference numerals and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it will not be further defined and explained in subsequent figures according to the embodiments of this application.

[0021] This application discloses an operation monitoring method and system for an indirect air-cooled tower. The operation monitoring method for an indirect air-cooled tower is based on an operation monitoring system for an indirect air-cooled tower. The purpose is to monitor the ambient wind parameters and the outlet water temperature of each cooling triangular unit of the air-cooled tower in real time and synchronously, thereby revealing the inherent influence law of the "thermal non-uniformity" phenomenon.

[0022] See attached document Figure 1 As shown, the operation monitoring method of this indirect air-cooled tower includes the following steps 110-140.

[0023] Step 110: During the operation of the indirect air-cooled tower, based on the unified clock reference provided by the data acquisition device according to the preset acquisition cycle, synchronously acquire the set of operating parameters reflecting the overall operating status of the indirect air-cooled tower, the set of environmental meteorological parameters including at least the ambient wind speed and the ambient wind direction, and the independent outlet water temperature data of each cooling triangular unit.

[0024] For example, the set of operating parameters includes the inlet water temperature of the radiator inlet header, the outlet water temperature of the radiator return header, and the circulating water flow rate of the circulating water header.

[0025] In some implementations, collecting the set of operating parameters includes: using a platinum resistance thermometer to collect the inlet water temperature of the radiator inlet header and the outlet water temperature of the radiator return header, wherein the resolution of the platinum resistance thermometer is not greater than 0.2℃ and the accuracy of the platinum resistance thermometer is not less than 0.5 grade; selecting a straight pipe section on the circulating water header with a length greater than 15 times the pipe diameter, installing an ultrasonic flow meter on the straight pipe section, wherein the installation position of the ultrasonic flow meter is not less than 10 times the pipe diameter from the upstream disturbance component and not less than 5 times the pipe diameter from the downstream disturbance component, and collecting the circulating water flow rate of the circulating water header based on the ultrasonic flow meter.

[0026] For example, the synchronous collection of the environmental meteorological parameter set, which includes at least environmental wind speed and environmental wind direction, includes: collecting environmental meteorological parameters at a preset distance upwind of the indirect air-cooled tower, wherein the preset distance is 30 to 50 meters away from the indirect air-cooled tower and the collection height is 1.5 meters above the ground; and collecting the environmental wind speed and environmental wind direction based on an anemometer with an accuracy of not less than ±0.1 m / s and an anemometer with an accuracy of not less than ±1°.

[0027] Preferably, the environmental meteorological parameter set includes environmental wind speed, environmental wind direction, environmental dry-bulb temperature, environmental relative humidity, and environmental atmospheric pressure. These environmental meteorological parameters are collected from meteorological stations.

[0028] For example, the independent outlet water temperature data of each cooling triangle unit is obtained by setting temperature measuring points on the outlet water pipes of each cooling triangle of the indirect air-cooled tower. The independent outlet water temperature data of each cooling triangle unit is the spatial distribution data of the circumferential outlet water temperature of the indirect air-cooled tower.

[0029] For example, the heat dissipation circumference (i.e., heat dissipation core) of the indirect air-cooled tower includes multiple independent cooling triangular units distributed along the circumference of the indirect air-cooled tower. For instance, the heat dissipation core of the indirect air-cooled tower is a heat dissipation ring composed of dozens (e.g., 15) cooling triangular units arranged along the circumference of the tower. Preferably, the multiple independent cooling triangular units are evenly distributed circumferentially along the circumference of the indirect air-cooled tower.

[0030] In some implementations, collecting independent outlet water temperature data for each cooling triangle unit includes: placing two thermometers on the outlet water pipe of each cooling triangle unit; reading the measured values ​​of the two thermometers and calculating the average value, using the average value as the outlet water temperature data of the current cooling triangle unit.

[0031] For example, each thermometer has a resolution of no more than 0.2°C and an accuracy of no less than 0.5%.

[0032] For example, the data acquisition device is a data acquisition card used to provide a unified clock reference.

[0033] Step 120: The collected environmental meteorological parameter set, the operating parameter set, and the independent outlet water temperature data of each cooling triangular unit are transmitted to the data processing center in real time.

[0034] For example, the data acquisition device is a data acquisition card, used to synchronously acquire, convert, and integrate the signals output by each sensor before sending them to the data processing center. Preferably, the data processing center is an industrial control computer.

[0035] For example, the collected environmental meteorological parameter set, the operational parameter set, and the independent outlet water temperature data of each cooling triangular unit are transmitted in real time to a data acquisition device (e.g., a high-precision multi-channel data acquisition card) via shielded data cables. This data acquisition card is responsible for performing analog-to-digital conversion on received analog signals (such as signals from platinum resistance thermometers, hygrometers, and pressure gauges) and protocol parsing and data integration on digital signals (such as signals from ultrasonic flow meters and anemometers). The data acquisition card uses a unified clock reference to ensure consistent time stamps for readings from different sensors. The integrated data is then uploaded in real time to a data processing center (e.g., an industrial control computer) using a standard industrial communication protocol through the data acquisition card's standard communication interface.

[0036] Step 130: The data processing center generates a unique timestamp for each acquisition cycle, and integrates the environmental meteorological parameter set, the operating parameter set, and the independent outlet water temperature data of each cooling triangular unit under the same timestamp to construct a comprehensive analysis dataset.

[0037] Each data record in this comprehensive analysis dataset includes a timestamp, the set of environmental meteorological parameters, the set of operating parameters, and multiple independent outlet water temperatures indexed by the cooling triangular unit number.

[0038] For example, in this application embodiment, the dedicated data acquisition and monitoring control software running on the industrial control computer (the data acquisition and monitoring control software is responsible for establishing a communication connection with the data acquisition card) receives and parses data packets. Then, the parsed environmental meteorological parameters, operating parameters, and water temperature data of each cooling triangle outlet are stored in the real-time database along with their precise acquisition timestamps, completing the real-time transmission and aggregation of data, and preparing for the subsequent construction of a comprehensive analysis dataset.

[0039] Step 140: Under different environmental wind conditions and different operating conditions, analyze the non-uniformity variation of the outlet water temperature of each cooling triangular unit in the circumferential direction of the indirect air-cooled tower based on the comprehensive analysis dataset.

[0040] Step 140 is used to provide data support for subsequent wind protection measures for indirect air-cooled towers.

[0041] In some implementations, the method further includes: generating a distribution cloud map or analysis report based on the comprehensive analysis dataset to reflect the circumferential outlet water temperature of the cooling tower under specific environmental wind conditions, the distribution cloud map or analysis report being used to guide wind resistance optimization of the indirect air-cooled tower.

[0042] For example, after obtaining the comprehensive analysis dataset, step 140 uses data analysis software running on the industrial control computer to analyze the uneven circumferential heat dissipation of the indirect air-cooled tower caused by ambient wind under different ambient wind conditions and different operating conditions.

[0043] Specifically, the analysis of the uneven circumferential heat dissipation of the indirect air-cooled tower caused by ambient wind includes: data screening and grouping, quantitative analysis of non-uniformity, and correlation and visualization of patterns.

[0044] For example, data filtering and grouping include: filtering data records from the database during periods of relatively stable operating conditions (such as circulating water flow rate and total inlet water temperature). The data records are then grouped according to different environmental wind parameters, for example, by environmental wind speed (e.g., 0-2 m / s for light wind, 2-4 m / s for moderate wind), or by environmental wind direction relative to the air-cooled tower (e.g., one sector per 45 degrees). Non-uniformity quantification analysis includes: for each group of data under specific wind conditions, calculating the standard deviation, range (difference between the highest and lowest temperatures), or coefficient of variation of temperature distribution for the outlet water temperature of each cooling triangular unit within that group of data records. This serves as a key indicator for quantifying the non-uniformity of the tower's circumferential outlet water temperature. Pattern correlation and visualization include: performing correlation analysis between the calculated non-uniformity indicators and the corresponding environmental wind speed and direction. For example, a curve showing the non-uniformity indicator changing with wind speed under a specific wind direction can be plotted, or a cloud map showing the distribution of the tower's circumferential outlet water temperature under a specific wind speed can be drawn. Analyzing these charts clearly reveals the following patterns: different wind directions lead to the appearance of high-temperature and low-temperature zones at specific locations around the tower; as wind speed increases, temperature unevenness may exhibit dynamic changes such as initial aggravation followed by mitigation or continuous aggravation. Based on the above analysis results, the cooling triangle unit area most susceptible to adverse effects from ambient wind can be accurately located, thus providing precise data and theoretical support for subsequent design of targeted wind protection and airflow guidance measures (such as installing windbreaks or optimizing the design of airflow deflectors in this area).

[0045] This application first synchronously collects a multi-dimensional parameter set based on a unified clock reference, ensuring strict temporal synchronization and comparability of operating parameters reflecting the overall tower status, environmental wind parameters affecting tower operation, and water temperatures of each triangular unit reflecting the local state of the tower. This lays a solid foundation for establishing accurate correlations later. Secondly, the above three types of data are transmitted to the data processing center in real time, ensuring the effective aggregation of massive amounts of monitoring data in terms of immediacy and completeness. This avoids analytical distortion caused by data transmission delays or losses, providing a guarantee for constructing a continuous and reliable analytical dataset. Next, the three types of data are correlated and integrated using timestamps to construct a comprehensive analytical dataset with a specific structure. This allows the tower's operating conditions, external environmental excitations, and internal circumferential temperature distribution response at each moment to be completely encapsulated in a single data record, greatly enhancing the inherent correlation of the data and the convenience of analysis. Finally, based on this dataset, the temperature non-uniformity variation pattern under different wind and operating conditions can be analyzed. This allows the influence of environmental wind to be separated from the complex operating state, revealing the key wind field characteristics and dynamic mechanisms leading to uneven heat dissipation. This provides a direct and scientific decision-making basis for implementing precise and efficient wind protection optimization measures.

[0046] See attached document Figure 2 As shown, this application also discloses an operation monitoring system for an indirect air-cooled tower, used to implement the above-described operation monitoring method for an indirect air-cooled tower. The heat dissipation circumference of the indirect air-cooled tower body includes multiple independent cooling triangular units distributed along the circumference of the indirect air-cooled tower. The operation monitoring system for the indirect air-cooled tower includes: a data acquisition module 210, a data transmission module 220, a comprehensive analysis dataset construction module 230, and an effluent status analysis module 240.

[0047] For example, the data acquisition module 210 is used to synchronously acquire, during the operation of the indirect air-cooled tower, a set of operating parameters reflecting the overall operating status of the indirect air-cooled tower, a set of environmental meteorological parameters including at least the ambient wind speed and the ambient wind direction, and independent outlet water temperature data of each cooling triangular unit, based on a unified clock reference provided by the data acquisition device according to a preset acquisition cycle.

[0048] For example, the data transmission module 220 is used to transmit the collected environmental meteorological parameter set, the operating parameter set, and the independent outlet water temperature data of each cooling triangular unit to the data processing center in real time.

[0049] For example, the comprehensive analysis dataset construction module 230 is used to generate a unique timestamp for each collection cycle by the data processing center, and to associate and integrate the environmental meteorological parameter set, the operating parameter set and the independent outlet water temperature data of each cooling triangular unit under the same timestamp to construct a comprehensive analysis dataset. Each data record in the comprehensive analysis dataset includes a timestamp, the environmental meteorological parameter set, the operating parameter set, and multiple independent outlet water temperatures indexed by the cooling triangular unit number.

[0050] For example, the water outlet status analysis module 240 is used to analyze the non-uniformity variation of the water outlet temperature of each cooling triangular unit in the circumference of the indirect air-cooled tower based on the comprehensive analysis dataset under different environmental wind conditions and different operating conditions.

[0051] The system has a simple structure and is easy to operate and implement. It can accurately monitor the impact of ambient wind on the outlet water temperature of the cooling tower, providing data support for subsequent wind protection measures for indirect air-cooled towers.
