Description

Technical Field

[0001] This invention relates to the field of air-cooled tower technology, and in particular to an analysis device and system for the maximum probability tower-side sector of an indirect air-cooled tower. Background Technology

[0002] Due to the uneven distribution of water resources in my country, and the severe water shortage in some areas, indirect air-cooling systems are widely used in coal-rich but water-scarce regions because of their significant advantages in water conservation.

[0003] The upward airflow within an indirect air-cooled tower is driven by the pressure difference created by the density difference between the air inside and outside the tower. Therefore, the thermodynamic characteristics of an indirect air-cooled tower are easily affected by environmental conditions, especially crosswinds. In complex building environments, surrounding buildings can alter the direction and speed of crosswinds, thus impacting the tower's heat exchange performance. If not optimized in time, excessive turbine back pressure can affect the unit's cycle efficiency, leading to reduced cooling efficiency of the indirect air-cooled tower and a decrease in power plant output. Therefore, optimizing indirect air-cooled towers is of paramount importance. Summary of the Invention

[0047] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] This invention provides a module for determining the maximum probability tower-side sector of an indirect air-cooled tower, comprising: an information acquisition module for acquiring the inlet air direction, inlet air velocity, and windward inlet angle of each sector of the indirect air-cooled tower under year-round operating conditions; a judgment and calculation module for judging whether the inlet air direction of each sector meets preset conditions, and if so, obtaining the actual inlet angle of each sector based on the inlet air direction and windward inlet angle; a tower-side angle deviation value calculation module for obtaining the tower-side angle deviation value by calculating the difference between the actual inlet angle and a preset value; a circumferential average wind speed calculation module for obtaining the circumferential average wind speed of each sector based on the inlet air velocity and the cosine value of the calculated tower-side angle deviation value; and a maximum probability tower-side sector determination module for determining the maximum probability tower-side sector of the indirect air-cooled tower based on the tower-side angle deviation value and the circumferential average wind speed of each sector.

[0049] Therefore, this invention provides a scheme for determining the most probable tower-side sector of an indirect air-cooled tower under complex building environments. By measuring the inlet air velocity and direction values ​​of each sector under year-round operating conditions, the actual inlet angle and tower-side angle deviation values ​​of each sector are calculated. The frequency of occurrence of the sector with the minimum tower-side angle deviation value is also counted, and the circumferential average wind speed of each sector is calculated. This invention comprehensively considers the above factors to finally determine the most probable tower-side sector of an indirect air-cooled tower under complex building environments under year-round operating conditions. This lays the groundwork for the subsequent optimization of the tower-side sector of the indirect air-cooled tower and provides theoretical support for the transformation of the cooling performance of the indirect air-cooled tower.

[0050] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0051] Specifically, the present invention provides an analysis device for the maximum probability tower-side sector of an indirect air-cooled tower, the specific functions of each module included are as follows:

[0052] The information acquisition module is used to acquire the air inlet direction, air inlet speed, and windward angle of each sector of the indirect air-cooled tower under year-round operating conditions.

[0053] like Figure 1 As shown, the information acquisition module is implemented in the following steps:

[0054] S11. Based on the annual wind direction frequency map of the local area where the indirect air-cooled tower is located and the location information of each sector, determine the windward angle of each sector.

[0055] Based on the annual wind direction frequency diagram of the location of the indirect air-cooled tower, the windward and inlet angles of sectors 1 to n are divided. The windward and inlet angles of sector 1 are α1 to α2, those of sector 2 are α1 to α2, and so on, with the windward and inlet angles of sector n being α1 to α2. n ~α1.

[0056] S12. Obtain the airflow direction and speed of each sector under the year-round operating conditions using several anemometers. Install an integrated anemometer at the airflow centerline of each of sectors 1 to n of the indirect air-cooled tower. The integrated anemometer measures the airflow speed v and airflow direction α of sectors 1 to n under the year-round operating conditions every m (1≤m) seconds.

[0057] S2. Determine whether the air intake direction of each sector meets the preset conditions. If the preset conditions are met, obtain the actual air intake angle of each sector based on the air intake direction and the windward air intake angle.

[0058] like Figure 2 As shown, the specific implementation of the judgment and retrieval module is as follows:

[0059] S21. Determine whether the air intake direction of each sector meets the preset conditions.

[0060] S2. If the conditions are met, the air inlet angle of each sector is obtained by calculating the difference between the average value of the air inlet direction and the average value of the windward air inlet angle of each sector. Based on the annual wind direction frequency map of the local area where the air-cooled tower is located and the location information of each sector, the range of the windward air inlet angle of each sector can be determined. Each sector has an upper limit and a lower limit for the windward air inlet angle range, and the average value of the windward air inlet angle is the average of the upper limit and the lower limit of the windward air inlet angle.

[0061] S23. If the air inlet angle is not greater than 180°, then the obtained air inlet angle shall be used as the actual air inlet angle of each sector.

[0062] S24. If the air inlet angle is greater than 180°, then the actual air inlet angle of each sector is the angle obtained by subtracting the air inlet angle from 360°.

[0063] If the air intake direction does not meet the preset conditions, the data is deleted and the result is output. That is, after deletion, this data is not included in the calculation, and the calculation directly iterates to the next set of air intake direction values. The preset conditions are 0° to 360°.

[0064] In the above steps, the difference between the air inlet direction α of sectors 1 to n of the indirect air-cooled tower and the average value of the windward air inlet angle of each sector is the air inlet angle β. r If the air intake angle β r ≤180°, the actual air inlet angle β = β for each sector r If the air inlet angle β r>180°, the actual air inlet angle β for each sector is 360° - β r The actual air inlet angle β for sectors 1 to n ranges from 0° to 180°.

[0065] S3. The tower side angle deviation value is obtained by calculating the difference between the actual air inlet angle and the preset value.

[0066] Furthermore, the tower side angle deviation value calculation module is implemented in the following specific steps:

[0067] The difference between the actual air inlet angle and the preset value of 90° is calculated, and the absolute value of the difference is processed to obtain the tower side angle deviation value.

[0068] S4. Based on the intake wind speed and the cosine value of the obtained tower side angle deviation, obtain the circumferential average wind speed of each sector.

[0069] like Figure 3 As shown, the module for calculating the circumferential average wind speed specifically implements the following steps:

[0070] S41. Calculate the cosine value of the tower side angle deviation value based on the tower side angle deviation value of each sector.

[0071] S42. The circumferential average wind speed of each sector is obtained by multiplying the inlet wind speed and the cosine of the tower side angle deviation.

[0072] The product of the inlet air velocity v in sectors 1 to n of the indirect air-cooled tower under year-round operating conditions and the cosine of the actual inlet air angle cosβ is the circumferential average air velocity, i.e.

[0073] S5. Based on the tower side angle deviation value and circumferential average wind speed of each sector, determine the most probable tower side sector of the indirect air-cooled tower.

[0074] like Figure 4 As shown, the module for determining the maximum probability tower-side sector is implemented in the following steps:

[0075] S51. Obtain the minimum tower side angle deviation value and the number of times the minimum tower side angle deviation value occurs for each sector. After obtaining the tower side angle deviation value for each sector, count the number of times the minimum tower side angle deviation value of sectors 1 to n occurs under the annual operating conditions of the indirect air-cooled tower.

[0076] S52. Based on the minimum value of the tower side angle deviation value of each sector, the number of times the minimum value of the tower side angle deviation value occurs, and the magnitude of the circumferential average wind speed, determine the maximum probability tower side sector of the indirect air-cooled tower.

[0077] Furthermore, the sector that satisfies the following conditions the most is the tower-side sector with the highest probability: the smallest tower-side angle deviation value, the most frequent occurrence of the minimum tower-side angle deviation value, and the largest circumferential average wind speed. That is, the sector with the smallest tower-side angle deviation value among sectors 1 to n of the indirect air-cooled tower is preferably the tower-side sector; the sector with the most frequent occurrence of the minimum tower-side angle deviation value among sectors 1 to n of the indirect air-cooled tower is preferably the tower-side sector; and the sector with the largest circumferential average wind speed among sectors 1 to n of the indirect air-cooled tower is preferably the tower-side sector.

[0078] In a specific embodiment, the above scheme is described using the operating conditions of an indirect air-cooled tower (June to September), and the specific implementation process is as follows:

[0079] First, for a 1000MW unit's natural draft indirect air-cooled tower, based on the prevailing wind direction of the location of the indirect air-cooled tower and the original location distribution of each sector of the indirect air-cooled tower, the windward angles of sectors 1 to 12 of the indirect air-cooled tower are determined. For example... Figure 5 As shown, the wind direction from the east is 0°, the wind direction from the south is 90°, the wind direction from the west is 180°, and the wind direction from the north is 270°. The windward inlet angles for sector 1 are 30°–60°, for sector 2 they are 0°–30°, for sector 3 they are 330°–360°, for sector 4 they are 300°–330°, for sector 5 they are 270°–300°, for sector 6 they are 240°–270°, for sector 7 they are 210°–240°, for sector 8 they are 180°–210°, for sector 9 they are 150°–180°, for sector 10 they are 120°–150°, for sector 11 they are 90°–120°, and for sector 12 they are 60°–90°.

[0080] Secondly, the incoming air velocity v and incoming air direction α are measured every 5 seconds using an integrated anemometer, and the above data are statistically analyzed in real time.

[0081] Next, determine whether the measured air inlet direction values ​​of sectors 1 to 12 of the indirect air-cooled tower meet the condition 0°≤α≤360°. If yes, calculate the actual air inlet angle of sectors 1 to 12; otherwise, delete the data and output the result.

[0082] Subsequently, the difference between the air inlet direction α of sectors 1 to 12 of the indirect air-cooled tower and the average windward air inlet angle of each sector is calculated as the air inlet angle β. r If the air intake angle β r ≤180°, the actual air inlet angle β = β for each sector r If the air inlet angle β r>180°, the actual air inlet angle β for each sector is 360° - β r The absolute value of the difference between the actual air inlet angle of sectors 1 to 12 of the indirect air-cooled tower and 90° is the tower side angle deviation value θ of each sector, i.e., θ = |90° - β|.

[0083] Table 1. Summer (June to September) Operating Conditions: Sector Data for Sectors 1-12

[0084]

[0085] Refer to Table 1 and Figure 6 The tower side angle deviation values ​​of sectors 1 to 12 of the indirect air-cooled tower under summer operating conditions were calculated and the data were statistically recorded. Comparing the side angle deviation values ​​of sectors 1 to 12 under summer operating conditions, it can be seen that the sectors with the smallest side angle deviation values ​​under summer operating conditions are, in descending order, sector 5, sector 6, sector 12, sector 9, sector 8, and sector 11.

[0086] Refer to Table 1 and Figure 7 The frequency of occurrence of the minimum tower-side angle deviation value in sectors 1-12 of the indirect air-cooled tower under summer operating conditions was statistically analyzed and recorded. Comparing the frequency of occurrence in sectors 1-12 under summer operating conditions, the sectors with the most frequent occurrences of the minimum tower-side angle deviation value are, in descending order: sector 5, sector 6, sector 12, sector 7, sector 8, sector 9, sector 8, and sector 11.

[0087] Refer to Table 1 and Figure 8 The circumferential average wind speed of sectors 1 to 12 of the indirect air-cooled tower under summer operating conditions was calculated, and the data was statistically recorded. Comparing the circumferential average wind speed of sectors 1 to 12 under summer operating conditions, it can be seen that the sectors with the largest circumferential average wind speed among sectors 1 to 12 under summer operating conditions are, in descending order, sector 5, sector 6, sector 12, sector 9, sector 8, and sector 11.

[0088] Therefore, in this implementation case, under summer operating conditions, sector 5 has the smallest side angle deviation value among sectors 1-12 of the indirect air-cooled tower. Sector 5 also has the highest frequency of occurrence of the sector with the smallest tower side angle deviation value, and it also has the highest circumferential average wind speed. Therefore, sector 5 can be determined as the most probable tower side sector for the indirect air-cooled tower under summer operating conditions. This method is also applicable to determining the most probable tower side sector under year-round operating conditions.

[0089] Furthermore, the present invention provides an analysis system for the maximum probability tower-side sector of an indirect air-cooled tower, comprising: a plurality of anemometers and wind direction meters disposed at the air inlet centerline of each sector; and the analysis device for the maximum probability tower-side sector of the indirect air-cooled tower as described above, which is communicatively connected to the plurality of anemometers and wind direction meters.

All systems / devices used in the methods of the above embodiments of the present invention fall within the scope of protection of the present invention.

[0091] Furthermore, this invention proposes a method for determining the most probable tower-side sector of an indirect air-cooled tower, comprising: first, obtaining the inlet air direction, inlet air velocity, and windward inlet angle of each sector of the indirect air-cooled tower under year-round operating conditions; second, determining whether the inlet air direction of each sector meets preset conditions, and if it does, obtaining the actual inlet angle of each sector based on the inlet air direction and windward inlet angle; next, obtaining the tower-side angle deviation value by calculating the difference between the actual inlet angle and the preset value; furthermore, obtaining the circumferential average wind speed of each sector based on the inlet air velocity and the cosine value of the calculated tower-side angle deviation value; and finally, determining the most probable tower-side sector of the indirect air-cooled tower based on the tower-side angle deviation value and the circumferential average wind speed of each sector.

[0092] Furthermore, the present invention also provides a computer-readable medium having computer-executable instructions stored thereon, which, when executed by a processor, implement a method for determining the maximum probability tower-side sector of an indirect air-cooled tower as described above.

[0093] In summary, this invention provides an analysis device and system for the maximum probability tower-side sector of an indirect air-cooled tower, which comprehensively considers the local annual wind direction frequency map and complex building environment of the indirect air-cooled tower, such as... Figure 9 As shown, the overall scheme of this invention is as follows: Based on the accurate measurement of the airflow direction and speed of sectors 1 to 12 under summer operating conditions, the statistical measurement data is judged to ensure that each set of data can be run. The actual airflow angle of sectors 1 to 12 is calculated, and then the tower side angle deviation value is obtained. The frequency of occurrence of the sector with the minimum tower side angle deviation value of sectors 1 to 12 under summer operating conditions is counted. The cosine value of the tower side angle deviation value and the circumferential average wind speed are calculated. By determining the sector with the minimum tower side angle deviation value under summer operating conditions, the sector with the most occurrences of the sector with the minimum tower side angle deviation value, and the sector with the highest circumferential average wind speed, the maximum probability tower side sector of the indirect air-cooled tower under summer operating conditions is determined. This invention determines the maximum probability tower side sector of the indirect air-cooled tower under given operating conditions, providing theoretical support and experimental numerical reference for subsequent indirect air-cooled tower cooling performance modification and antifreeze modification, and has certain practical engineering application value.
