Description

Technical Field

[0001] This invention relates to the field of combined cycle generator technology, specifically to an intelligent replacement early warning system for gas turbine intake filters. Background Technology

[0002] With the acceleration of industrialization and the increasing demand for electricity, combined cycle generator sets have been widely used in various fields. These sets typically consist of multiple generators and related auxiliary equipment, working together to ensure a stable power supply. During the operation of the set, the gas turbine intake filter plays a crucial role in capturing and removing impurities from the fluid, protecting the set from contamination and wear.

[0003] Traditional combined cycle generator gas turbine inlet filters typically employ a fixed replacement cycle, meaning they are replaced at regular intervals or after a certain number of hours of operation. However, this fixed-cycle replacement method has several drawbacks. First, due to significant differences in operating environments, load conditions, and fluid quality among different units, fixed-cycle replacement often fails to accurately reflect the actual usage condition of the gas turbine inlet filter. This can lead to premature replacement, resulting in wasted resources, or premature replacement, causing clogging or failure of the gas turbine inlet filter, ultimately affecting the stable operation of the entire unit.

[0004] Furthermore, with the continuous development of intelligent technologies, various industries are seeking intelligent and automated solutions to improve efficiency. In the field of combined cycle generator sets, although some intelligent monitoring and diagnostic systems have been applied to unit condition monitoring and fault early warning, systems specifically for filter condition monitoring and replacement reminders are still insufficient.

[0005] Therefore, developing an adaptive replacement reminder system for the gas turbine intake filter of a combined cycle generator set has significant practical importance and application value. This system can monitor the filter's usage status in real time, observe the filter's performance degradation trend based on the actual operating conditions of the unit, and intelligently remind the user when to replace the filter, thereby achieving precise filter replacement and efficient and stable operation of the unit.

[0006] Furthermore, since there are many tools used for replacement, it is not convenient to make adaptive adjustments according to the needs of replacing different models of filters. This results in the need to prepare different devices for different filters, leading to poor integration and practical effect. Summary of the Invention

[0007] The purpose of this invention is to provide an intelligent replacement early warning system for gas turbine intake filters, thereby ensuring that they are replaced at the appropriate time.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an intelligent replacement early warning system for a gas turbine intake filter, comprising at least a sensor module, a data processing module, an intelligent algorithm module, and an alert output module; The sensor module is responsible for collecting key parameters of the filter, including at least differential pressure and flow rate; The data processing module processes and analyzes the collected data to extract key indicators reflecting the filter's performance. The intelligent algorithm module trains a highly adaptable predictive model based on these indicators and the unit's operating data through methods such as machine learning or deep learning. The prompt output module provides the operator with prompt information to replace the filter based on the obtained results; It also includes an opening / closing module, a leak detection module, and a sensor replacement module; The opening and closing module is used in conjunction with the sensor module and the data processing module to control the opening and closing of the valve according to the specific pressure difference and flow rate, thereby facilitating the opening and inspection of the part equipped with the filter element after the valve is opened; The leak detection module is used in conjunction with the sensor module and the data processing module to detect leaks during replacement and startup. The replacement sensor module is used to connect the filter element to the air inlet pipe, thereby re-detecting the gas passing through the filter element, and then triggering an alarm based on whether the detected result reaches a threshold, and then replacing the filter element.

[0009] Furthermore, the replacement sensor module includes an alarm module, a detection module, a control calculation module, and an execution module, which are electrically connected to each other.

[0010] Furthermore, the execution module includes a housing, a guide tube, an auxiliary mounting box, a signal processing circuit board, a photosensitive reaction plate, a reflective mounting shell, a control switch, a spotlight, a diffuser plate, a guide post, and a flange. The guide tube is fixedly connected inside the housing, and flanges are fixedly connected to both ends of the guide tube. The execution module connects the filter element to the air inlet pipe via the flanges. A reflective mounting shell is fixedly connected to the top of the housing, and a control switch is fixedly connected to the top of the reflective mounting shell. A spotlight is fixedly connected to the inner side of the reflective mounting shell, and the control switch is electrically connected to the spotlight. A diffuser plate is fixedly connected to the inner wall of the top of the housing. A guide post is fixedly connected to the inner side of the guide tube. An auxiliary mounting box is fixedly connected to the bottom of the housing. A signal processing circuit board and a photosensitive reaction plate are disposed inside the auxiliary mounting box, and the photosensitive reaction plate is electrically connected to the signal processing circuit board.

[0011] Furthermore, the intelligent algorithm module is used to match the replacement of the sensor module for linkage application. The intelligent algorithm module is equipped with an algorithm to design a replacement reminder based on the amount of ash entering the filter after the sensor module is replaced. The replacement reminder algorithm is to build an effective replacement reminder mechanism by combining real-time monitored ash entering data, the rated capacity of the filter and historical usage data.

[0012] Furthermore, the algorithm for replacing reminders includes at least the following steps: S1: Data acquisition and preprocessing: The real-time ash inlet monitoring data exported from the sensor module replacement is converted into data and recorded in the form of a time series. S2: Data cleaning, removing outliers or noisy data to ensure data accuracy and reliability; S3: Rated capacity setting, determines the rated capacity of the filter, that is, the maximum amount of ash that the filter can handle under design conditions; S4: Performance degradation assessment. Based on historical data, analyze the performance degradation trend of the filter. Over time, the filtration efficiency of the filter will gradually decrease, and this factor needs to be considered in the replacement reminder algorithm. S5: Construct a replacement reminder algorithm, prioritize the calculation of remaining capacity, and calculate the remaining capacity of the filter based on real-time ash intake data and the rated capacity of the filter; Remaining capacity = Rated capacity - Cumulative ash intake; Replacement threshold setting: Based on the performance degradation trend of the filter and actual operating requirements, set a reasonable replacement threshold. When the remaining capacity is lower than this threshold, a reminder should be given to replace the filter. S6: Dynamic adjustment strategy. Considering the performance differences of filters under different operating environments and load conditions, the algorithm can introduce a dynamic adjustment strategy to adjust the replacement threshold in real time according to factors such as unit load and fluid quality. S7: Early warning mechanism. Before the replacement threshold is reached, a multi-level early warning mechanism is set up to notify operators in advance to pay attention to the usage of the filter so that they can prepare for replacement.

[0013] Furthermore, the replacement reminder algorithm is implemented using suitable Python and C++ to ensure its real-time performance and accuracy. The interface of the intelligent algorithm module is integrated into the unit's monitoring system, displaying the filter's usage and replacement reminder information through a graphical interface for easy viewing and management by operators.

[0015] Furthermore, the filter element disassembly and replacement device includes an external component, a second limit adjustment and driving component, and a linkage component. The filter element disassembly and replacement device is used to easily remove the fixing shell outside the filter element and clamp and retrieve the filter element. The external components include a second grip, a lower bottom shell, and a second limit adjustment drive assembly. The top of the lower bottom shell is connected to an upper top shell by screws. The second grip is welded to one end of the lower bottom shell. Multiple guide limit slide grooves are evenly distributed on the inner side of the upper top shell. A second reserved groove is opened on the side of the guide limit slide groove. Symmetrical reserved holes are opened on both sides of the guide limit slide groove at the top of the upper top shell.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0023] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the invention can be combined with each other.

[0024] Example 1: See Figure 1 , Figures 9-10 The intelligent replacement early warning system for gas turbine intake filters in this embodiment includes at least a sensor module, a data processing module, an intelligent algorithm module, and an alert output module. The sensor module is responsible for collecting key parameters of the filter, including at least differential pressure and flow rate; The data processing module processes and analyzes the collected data to extract key indicators that reflect the performance of the filter; Based on these indicators and the unit's operating data, the intelligent algorithm module trains a highly adaptable predictive model using methods such as machine learning or deep learning. The prompt output module provides the operator with prompt information to replace the filter based on the obtained results; The present invention also includes an opening and closing module, a leakage detection module, and a sensor replacement module; The opening and closing module is used in conjunction with the sensor module and data processing module to control the opening and closing of the valve according to the specific pressure difference and flow rate, so as to facilitate the opening and inspection of the part with the filter element after the valve is opened; The leak detection module is used in conjunction with the sensor module and data processing module to detect leaks during replacement and startup. The sensor module is replaced to connect the filter element to the air intake pipe, thereby re-detecting the gas passing through the filter element. Based on the detection results, an alarm is triggered to determine whether the threshold is reached, and the filter element is then replaced.

[0025] The replacement sensor module includes an alarm module, a detection module, a control calculation module, and an execution module. The alarm module, detection module, control calculation module, and execution module are electrically connected to each other.

[0026] The execution module includes a housing 30, a guide tube 31, an auxiliary mounting box 32, a signal processing circuit board 33, a photosensitive reaction plate 34, a reflective mounting shell 35, a control switch 36, a spotlight 37, a diffuser plate 38, a guide post 39, and a flange 40. The guide tube 31 is fixedly connected inside the housing 30, and flanges 40 are fixedly connected to both ends of the guide tube 31. The execution module connects the filter element to the air inlet pipe via flanges 40. A reflective mounting shell 35 is fixedly connected to the top of the housing 30. A control switch 36 is fixedly connected to the top of the housing 35. A spotlight 37 is fixedly connected to the inner side of the reflective housing 35. The control switch 36 and the spotlight 37 are electrically connected. A diffuser plate 38 is fixedly connected to the inner wall of the top of the housing 30. A guide post 39 is fixedly connected to the inner side of the guide tube 31. An auxiliary mounting box 32 is fixedly connected to the bottom of the housing 30. A signal processing circuit board 33 and a photosensitive reaction plate 34 are arranged inside the auxiliary mounting box 32. The photosensitive reaction plate 34 and the signal processing circuit board 33 are electrically connected.

[0027] Since the execution module is located at the position of the filtered air, the filtered air needs to pass through the execution module to detect the amount of dust inside in order to ensure the working capacity of the filter element. When the amount of dust increases to more than the threshold, it makes a comprehensive judgment based on the threshold given by the manufacturer, so as to better grasp the timing of replacing the intake filter element. The specific detection principle is as follows: The light illuminating the spotlight 37 is diffused and amplified by the light diffuser 38 through the principle of its own convex lens, so that the light comes into contact with the filtered air introduced into the auxiliary mounting box 32 through the guide tube 31. When dust in the air is irradiated, due to the semi-light absorption principle of dust, it will block the light that is fully irradiated on the surface of the photosensitive reaction plate 34, producing a partial shadow and forming multiple small dots. When the small dots are on the surface of the photosensitive reaction plate 34, they form small circuit signals. These signals are processed and amplified by the signal processing circuit board 33 and transmitted to the control calculation module. The amount of dust in the filtered air is then judged based on the number of small dots, thereby determining the corresponding value.

[0028] The intelligent algorithm module is used to match the replacement of sensor modules for linkage applications. The intelligent algorithm module is equipped with an algorithm designed to remind users to replace the sensor modules based on the amount of ash entering the filter after replacement. The replacement reminder algorithm combines real-time monitored ash data, the rated capacity of the filter, and historical usage data to build an effective replacement reminder mechanism.

[0029] Setting up an algorithm for changing reminders includes at least the following steps: S1: Data acquisition and preprocessing: The real-time ash inlet monitoring data exported from the sensor module replacement is converted into data and recorded in the form of a time series. S2: Data cleaning, removing outliers or noisy data to ensure data accuracy and reliability; S3: Rated capacity setting, determines the rated capacity of the filter, that is, the maximum amount of ash that the filter can handle under design conditions; S4: Performance degradation assessment. Based on historical data, analyze the performance degradation trend of the filter. Over time, the filtration efficiency of the filter will gradually decrease, and this factor needs to be considered in the replacement reminder algorithm. S5: Construct a replacement reminder algorithm, prioritize the calculation of remaining capacity, and calculate the remaining capacity of the filter based on real-time ash intake data and the rated capacity of the filter; Remaining capacity = Rated capacity - Cumulative ash intake; Replacement threshold setting: Based on the performance degradation trend of the filter and actual operating requirements, set a reasonable replacement threshold. When the remaining capacity is lower than this threshold, a reminder should be given to replace the filter. S6: Dynamic adjustment strategy. Considering the performance differences of filters under different operating environments and load conditions, the algorithm can introduce a dynamic adjustment strategy to adjust the replacement threshold in real time according to factors such as unit load and fluid quality. S7: Early warning mechanism. Before the replacement threshold is reached, a multi-level early warning mechanism is set up to notify operators in advance to pay attention to the usage of the filter so that they can prepare for replacement.

[0030] The replacement reminder algorithm is implemented using appropriate Python and C++ to ensure its real-time performance and accuracy. The interface of the intelligent algorithm module is integrated into the unit's monitoring system, displaying the filter usage and replacement reminder information through a graphical interface for easy viewing and management by operators.

[0031] Example 2: The intelligent replacement early warning system for the gas turbine intake filter in this embodiment, based on embodiment 1, further includes a nut replacement device and a filter element disassembly and replacement device. The nut replacement device facilitates the adjustment of different locking nuts on the filter to meet specific usage requirements, thereby avoiding the need to carry multiple different wrenches during replacement and achieving better replacement optimization.

[0032] The inclusion of a filter element removal and replacement device facilitates matching with different filter housing diameters, achieving better applicability.

[0033] Example 3: See Figures 2-8Based on Example 2, the nut replacement device includes a main body, a first limit adjustment drive assembly 3, a clamping pressure plate 4, a matching drive assembly 5, and a transmission component. The nut replacement device is used to loosen the nuts fixed to the outside of the filter. The main components include a first handle 1 and a wrench body 2. The transmission components include a first gear 12, an upper gear ring 7, and a lower gear ring 8. The wrench body 2 is fixedly connected to one side of the first handle 1. A first limit adjustment drive assembly 3 is provided at one end of the wrench body 2. An upper gear ring 7 is provided at the top of the inner side of the wrench body 2, and a lower gear ring 8 is provided at the bottom of the inner side of the wrench body 2. Multiple first gears 12 are meshed between the upper gear ring 7 and the lower gear ring 8. A first reserved groove 6 is provided inside the wrench body 2 corresponding to the position of the first gear 12.

[0034] The clamping plate 4 includes a ball-head push rod 9, a first spring 10, an inclined plane adjustment push rod 11, and a linkage displacement rod 13. The linkage displacement rod 13 is fixedly connected to the inner side of the first gear 12. One end of the linkage displacement rod 13 is rotatably connected to the wrench body 2, and the other end of the linkage displacement rod 13 is fixedly connected to the inclined plane adjustment push rod 11. The linkage displacement rod 13 corresponding to the position of the first limit adjustment drive component 3 extends out of the wrench body 2. The inclined plane adjustment push rod 11 is an inclined cut cylinder. The clamping plate 4 is provided with a first spring 10 and a ball-head push rod 9 at one end near the inclined plane adjustment push rod 11. The first spring 10 is located on both sides of the ball-head push rod 9. The end of the first spring 10 away from the clamping plate 4 is fixedly connected to the wrench body 2. The ball-head push rod 9 passes through the wrench body 2 and fits against the inclined plane adjustment push rod 11.

[0035] The first limit adjustment drive assembly 3 includes a mounting positioning plate 14, a matching tooth groove 15, a rotating plate 16, a second spring 17, and a beveled paddle 18. One end of the mounting positioning plate 14 is fixedly connected to the wrench body 2. Multiple matching tooth grooves 15 are provided on the inner side of the mounting positioning plate 14. One end of the rotating plate 16 at the first limit adjustment drive assembly 3 is fixedly connected to the end of the linkage displacement rod 13 extending out of the wrench body 2. A receiving groove is provided on the inner side of the rotating plate 16. The second spring 17 is provided on the inner wall of the receiving groove. The beveled paddle 18 is provided on the end of the second spring 17 away from the inner wall of the receiving groove. The beveled paddle 18 and the matching tooth groove 15 are in clearance fit.

[0036] When it is necessary to disassemble the filter element, some nuts or screws need to be loosened. In order to loosen the nuts, the nut replacement device in this embodiment is used, and the specific application is as follows: Holding the first handle 1, place the clamping plate 4 outside the nut. When it is necessary to adjust the clamping plate 4 to fit the nut, continuously press down the inclined plate 18, causing the inclined plate 18 to squeeze the second spring 17 into the receiving groove in the rotating disk 16. The inclined plate 18 disengages from the inner side of the adjusting tooth groove 15, thereby causing the rotating disk 16 to lose its limit. At this time, rotating the rotating disk 16 causes the rotating disk 16 to drive the linkage displacement rod 13 connected to it to rotate, and simultaneously drive the corresponding first gear 12 to rotate. At this time, by utilizing the meshing of the first gear 12 with the lower gear ring 8 and the first gear 12 with the upper gear ring 7, the lower gear 12 is rotated. The gear ring 8 and the upper gear ring 7 rotate, which in turn drives the other first gears 12 to rotate synchronously. This rotation causes the inclined plane adjustment push rod 11 to rotate synchronously. The different thicknesses of the inclined plane adjustment push rod 11 cause the ball head push rod 9 to be pushed to different extension lengths during the contact process between the inclined plane adjustment push rod 11 and the ball head push rod 9. This pushes the clamping plate 4 closer to or further away from the corresponding nut. The first spring 10 provides auxiliary support and adjustment and retraction reset, thereby achieving the adjustment function. This allows the clamping plate 4 to fit against the nut surface, achieving the application of different sized nuts. After adjusting to the appropriate size, by releasing the pressure on the inclined plate 18, the second spring 17 loses pressure and resets itself through its own elasticity, removing the inclined plate 18 and inserting it into the corresponding adjusting groove 15, thereby completing the corresponding locking limit and preventing the limit from being lost after adjustment, which would cause the nut to loosen. Furthermore, by rotating the first handle 1, the nut can be rotated, thus better adapting to the use when replacing different filter elements.

[0037] Example 4: See Figures 6-8 Based on Example 3, the filter element disassembly and replacement device includes an external component, a second limit adjustment drive component 22 and a linkage component. The filter element disassembly and replacement device is used to easily remove the fixed shell outside the filter element and clamp and retrieve the filter element.

[0038] The external components include a second grip 19, a lower bottom shell 20, and a second limit adjustment drive assembly 22. The top of the lower bottom shell 20 is connected to an upper top shell 21 by screws. The second grip 19 is welded to one end of the lower bottom shell 20. Multiple guide limit slide grooves 23 are evenly distributed on the inner side of the upper top shell 21. A second reserved groove 28 is opened on the side of the guide limit slide groove 23. Symmetrical reserved holes 27 are opened on both sides of the guide limit slide groove 23 at the top of the upper top shell 21. The second limit adjustment drive assembly 22 is provided at the bottom of the lower bottom shell 20.

[0039] The linkage assembly includes a first gear shaft 24, a second gear shaft 25, a second gear 26, and a rack clamping block 29. Multiple sets of first gear shafts 24 and second gear shafts 25 are rotatably connected to the inner side of the lower bottom shell 20. The first gear shafts 24 and second gear shafts 25 are meshed together. The bottom end of the first gear shaft 24 corresponding to the position of the second limit adjustment drive assembly 22 extends out of the lower bottom shell 20. The second gear 26 is rotatably connected to the center of the lower bottom shell 20. The second gear shaft 25 is meshed with the second gear 26 at a point away from the first gear shaft 24. The rack clamping block 29 is slidably connected to the inner side of the guide limit slide groove 23. The top end of the second gear shaft 25 is meshed with the rack clamping block 29 through a reserved hole 27 and a second reserved groove 28.

[0040] The second limit adjustment drive assembly 22 includes a mounting positioning plate 14, a matching tooth groove 15, a rotating plate 16, a second spring 17, and an inclined plate 18. The top of the mounting positioning plate 14 is fixedly connected to the lower bottom shell 20. Multiple matching tooth grooves 15 are provided on the inner side of the mounting positioning plate 14. One end of the rotating plate 16 is fixedly connected to the end of the first gear shaft 24 extending out of the lower bottom shell 20. A receiving groove is provided on the inner side of the rotating plate 16. The second spring 17 is provided on the inner wall of the receiving groove. An inclined plate 18 is provided on the end of the second spring 17 away from the inner wall of the receiving groove. The inclined plate 18 and the matching tooth groove 15 are in clearance fit.

[0041] During use, the filter element housing needs to be clamped and then rotated to release it, and the filter element needs to be clamped and pulled out to fit the upper top shell 21 and the lower bottom shell 20 onto the filter element housing or the outside of the filter element. At this time, by pressing the inclined plate 18, the inclined plate 18 squeezes the second spring 17 into the receiving groove in the rotating disk 16, and the inclined plate 18 disengages from the inner side of the adjusting tooth groove 15, thereby causing the rotating disk 16 to lose its limit. At this time, rotating the rotating disk 16 causes the first gear shaft 24 to rotate. By utilizing the meshing of the first gear shaft 24 with the second gear shaft 25, and the meshing of the second gear shaft 25 with the second gear 26, multiple sets of second gear shafts 25 can rotate synchronously. By utilizing the meshing between the top end of the second gear shaft 25 and the rack clamping block 29, the rack clamping block 29 is forced to slide inside the guide limiting slide groove 23, thereby displacing and squeezing the rack clamping block 29 to a suitable position, thus completing the application of filter elements or filter element housings of different sizes.

[0042] After adjusting to the appropriate size, by releasing the pressure on the inclined plate 18, the second spring 17 loses pressure and resets itself through its own elasticity, allowing the inclined plate 18 to be inserted into the corresponding adjustment groove 15, thereby completing the corresponding locking limit and preventing the filter element or filter element shell from being loosened after the adjustment is completed.

[0043] This invention is not limited to the above-described optional embodiments. Anyone can derive other various forms of products under the guidance of this invention. However, regardless of any changes made in their shape or structure, any technical solution that falls within the scope of the claims of this invention shall be protected by this invention.
