Description

Technical Field

[0001] This invention relates to the field of power generation equipment operation control technology, specifically a dynamic collaborative control method for improving the ball collection rate of a condenser ball system. Background Technology

[0002] Currently, the safe and economical operation of thermal power plant generator units highly depends on the heat exchange efficiency of the condenser. The condenser ball cleaning system is a core auxiliary device for maintaining the cleanliness of the internal tube bundles and upholding the high vacuum level of the unit. The circulation status of the cleaning medium within the pipe network is directly reflected by the key indicator of the ball recovery rate. A consistently low ball recovery rate not only indicates a significant reduction in cleaning effectiveness but also signifies abnormal retention of a large amount of cleaning medium inside the equipment. This situation can lead to a continuous increase in the condenser terminal temperature difference, directly restricting the overall economic benefits of the thermal system.

[0003] Regarding the aforementioned issues, conventional ball-collecting system control and maintenance solutions primarily rely on single-path physical intervention. During routine operation, this typically involves extending the ball-collecting time of the water pump and soaking the cleaning medium in clean water before commissioning. During unit shutdowns for maintenance, personnel perform routine manual cleaning by opening the condenser water chamber. Some solutions involve adding large metal guide plates directly to the outlet bend section to alter the macroscopic flow field, or performing simple mechanical repairs and angle adjustments on deformed ball-collecting mesh plates and valves experiencing internal leakage, thereby maintaining the basic circulation flow of the cleaning medium.

[0004] Conventional treatment methods reveal significant limitations and systemic deficiencies. Simple macroscopic flow field intervention completely ignores the complex microscopic physical morphology within the equipment. The inherent geometric structures such as the grooves at the top of the titanium tubes in the condenser water chamber, the through-holes in the valve body reinforcing ribs, and the gaps between bolt columns constitute hidden fluid dead zones. Once the cleaning medium gets trapped in these mechanical dead zones, irreversible structural jamming can easily occur, and traditional surface maintenance simply cannot smooth out these naturally occurring stagnation points. Faced with fluctuations in operating conditions, isolated operational methods are powerless to address the dynamically accumulating air at the top of the water chamber. Coupled with the long-term absence of a physical density screening mechanism for the cleaning medium, the phenomenon of medium suspension and accumulation occurs frequently. This passive response mode heavily relies on arduous manual cleaning by shutting down and opening the cover, making dynamic intervention difficult, ultimately resulting in significant fluctuations and periodic declines in the actual ball collection rate of the system.

[0005] Therefore, this invention provides a dynamic collaborative control method to improve the ball collection rate of a condenser ball system, thereby addressing the shortcomings of existing technologies. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a dynamic collaborative control method for improving the ball collection rate of condenser ball cleaning systems. This method solves the technical problem that existing condenser ball cleaning systems suffer from severe retention of cleaning media due to internal flow field defects, gas accumulation, and microstructural dead angles, resulting in a long-term low and highly unstable ball collection rate.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a dynamic collaborative control method for improving the ball recovery rate of a condenser ball system, comprising the following steps:

[0008] Perform dynamic and coordinated adjustments at the operational level to adjust the hydrodynamic distribution inside the condenser ball system and eliminate the problem of cleaning medium retention caused by gas accumulation. Implement refined management of the quality and life cycle of the condenser balls, obtain the cleaning medium that meets the physical density standard, and alternately apply it to the condenser ball system; Conduct targeted investigation and permanent sealing of internal structural defects in the condenser to block the physical movement trajectory of the cleaning medium into the dead water zone; The pipe and valve structure and auxiliary system are comprehensively optimized and configured to change the internal flow field distribution state, so as to make the cleaning medium evenly distributed and impact the ball collecting plate. Based on long-term ball collection rate diagnostic results, a systematic overall upgrade and transformation will be selectively implemented to reshape the internal flow channel boundary; To conduct dynamic verification of the effectiveness and economic benefit evaluation of the glue ball system, the absolute quantity of the cleaning medium input and recovery in a single cycle was obtained, the actual ball recovery rate parameters were obtained, and the physical effect verification was completed.

[0009] By adopting the above technical solutions, the use of multi-layered dynamic intervention combined with flow field reshaping and physical gap sealing eliminates the medium retention caused by dead zones and gas accumulation inside the system, optimizes operating parameters and physical properties of the medium, and thus achieves the effect of smooth movement trajectory of the cleaning medium, complete blockage of physical loss paths, and stable improvement of overall ball collection rate.

[0010] Preferably, the specific steps for performing dynamic coordinated adjustment at the operational level are as follows: obtaining the number of circulating water pumps in operation and their operating status; when the condenser ball system is in single-pump operation mode, placing the condenser ball system in ball-collecting mode for continuous operation for two hours; after the condenser ball system has been running for two hours, starting the second circulating water pump in standby mode, so that the single circulating water pump and the second circulating water pump in standby mode run in parallel for thirty minutes, performing dynamic coordinated adjustment at the operational level, adjusting the water flow dynamic distribution inside the condenser ball system, increasing the water flow dynamic and velocity inside the pipeline system, discharging the gas accumulated at the top of the return water chamber, and eliminating the problem of cleaning medium retention caused by the gas accumulation.

[0011] By adopting the above technical solution, the water flow dynamics are increased to forcefully expel accumulated gas and eliminate the suspended dead zone of the cleaning medium.

[0012] Preferably, the dynamic coordinated adjustment at the execution operation level further includes the following specific steps for implementing a closed-loop confirmation mechanism for the tightness of the ball-collecting net: detecting the physical closed position of the ball-collecting net plate; switching the control mode of the ball-collecting net plate to manual mode via a mechanical transmission mechanism, performing a mechanical tightening operation on the ball-collecting net plate, in conjunction with the dynamic coordinated adjustment at the execution operation level; completing the closed-loop confirmation mechanism for the tightness of the ball-collecting net through the mechanical tightening operation, controlling the edge of the ball-collecting net plate to form a physical seal with the pipe wall, and blocking the physical movement path of the cleaning medium from flowing out of the mechanical gap between the ball-collecting net plate and the pipe wall.

[0013] By adopting the above technical solution, the gaps at the edges of the ball-collecting net are closed, blocking the physical path of ball leakage.

[0014] Preferably, the specific steps for implementing refined management of the quality and lifecycle of the cleaning media are as follows: A preset number of new cleaning media are placed inside an immersion container; fluid is injected into the immersion container so that all the new cleaning media are completely submerged below the surface of the fluid; the new cleaning media are placed in warm water and continuously immersed, allowing the internal pores of the new cleaning media to absorb the warm water, causing the volume of the new cleaning media to expand and reach the set working physical dimensions; the physical density data of a single new cleaning media is obtained, and the physical density parameter of the new cleaning media is limited to between 1.0 grams per cubic centimeter and 1.15 grams per cubic centimeter; new cleaning media with physical densities outside the limited range are discarded, thus completing the refined management of the quality and lifecycle of the cleaning media and obtaining cleaning media that meet the physical density standard.

[0015] By adopting the above technical solutions, it is ensured that the cleaning medium reaches the set size and matches the density of the water, thus preventing the medium from settling or suspending.

[0016] Preferably, the refined management of the condenser ball quality and lifecycle further includes the following specific steps for performing alternating use of dual-color condenser balls and ball accumulation location analysis: First, a first cleaning medium with a first color attribute and a second cleaning medium with a second color attribute are obtained. During the continuous operation cycle of the condenser ball system, the first and second cleaning media are alternately used in the condenser ball system, performing the alternating use of dual-color condenser balls. At the media recovery end of the condenser ball system, the absolute quantities of the first and second cleaning media recovered in a single cycle are obtained, and the ratio of the absolute quantities of the first and second cleaning media is calculated. When the absolute quantity of the first cleaning medium obtained at the media recovery end exceeds a preset benchmark value, the time node data of the sudden increase in the quantity of the first cleaning medium is obtained. Combined with the fluid velocity parameters in the pipeline of the condenser ball system, the physical distance from the media retention point to the media recovery end is calculated, and the physical location of the cleaning medium retained inside the condenser is determined, thus completing the ball accumulation location analysis and the refined management of the condenser ball quality and lifecycle.

[0017] By adopting the above technical solution, the historical ball accumulation location can be accurately located by combining the difference in the quantity of the two-color medium with the flow velocity data.

[0018] Preferably, the specific steps for targeted investigation and permanent sealing of internal structural defects in the condenser are as follows: For the square grooves present at the top of the titanium pipes in the condenser circulating water inlet chamber, silicone structural sealant is used for internal filling, thus conducting targeted investigation and permanent sealing of the internal structural defects in the condenser; For the fastening bolts distributed around the backwash valve housing in the condenser circulating water inlet chamber, a nylon protective sleeve is wrapped around the bolt post of each fastening bolt, and a stainless steel clamp is used to close the nylon protective sleeve for rigid locking; For the physical pits formed by the connecting valve in the condenser inlet and outlet chambers at the outlet chamber structure and the through holes formed by the reinforcing ribs of the connecting valve, closed-cell polyurethane foam is injected into the through holes, and a quick-release nylon rope net is fixed above the physical pits via a flange connection to block the physical movement trajectory of the cleaning medium into the dead water zone.

[0019] By adopting the above technical solution, the internal geometric gaps and pits are filled, and the medium jamming points at the structural level are eliminated.

[0020] Preferably, the specific steps for the comprehensive optimization configuration of the valve structure and auxiliary system are as follows: A reconfigured flow guide component is installed on the ball-collecting mesh plate, and a vertical baffle plate is welded and fixed at the bottom of the ball-collecting mesh plate to eliminate the dead water zone; a metal flow guide plate is welded and added inside the condenser outlet bend section to physically converge and guide the flow field of the medium flowing through the condenser outlet bend section, completing the comprehensive optimization configuration of the valve structure and auxiliary system, changing the internal flow field distribution to promote uniform distribution of the cleaning medium and its impact on the ball-collecting mesh plate; an auxiliary test pipeline is laid between the ball outlet pipe outlet of the ball-loading chamber and above the condenser outlet bend section, and a full-opening one-way valve is installed at the ball outlet of the power generation equipment's ball-loading chamber to physically block the reverse flow path of the cleaning medium.

[0021] By adopting the above technical solutions, the local water flow velocity distribution is optimized, preventing the cleaning medium from flowing out of control, accumulating, or flowing back.

[0022] Preferably, the comprehensive optimization configuration of the pipe and valve structure and auxiliary system further includes the following specific steps for hydraulic control of air accumulation treatment in the return water chamber: when the monitoring system detects air accumulation at the top of the return water chamber, as part of the comprehensive optimization configuration of the pipe and valve structure and auxiliary system, the control system sends a pump start command to start the circulating water pump in standby mode; the circulating water pump in standby mode provides additional hydraulic head and flow increment after being connected to the pipe network, driving the air accumulated at the top of the return water chamber to be forcibly discharged from the outside of the system pipe network with high-speed water flow, thus completing the hydraulic control of air accumulation treatment in the return water chamber.

[0023] By adopting the above technical solution, the backup water pump provides an increased flow rate to force air release, thus avoiding stagnation caused by a lack of liquid level at the top.

[0024] Preferably, the specific steps for selectively implementing a systematic overall upgrade based on long-term ball collection rate diagnostic results are as follows: Obtain historical collection data within a set time period and calculate the average ball collection rate; based on the long-term ball collection rate diagnostic results, if the average ball collection rate value is consistently below the threshold of 85%, physically remove the originally installed guide plates and fixed support components inside the condenser water chamber and related pipelines; selectively implement the systematic overall upgrade by rotating the installation orientation of the ball collection mesh plate by 90 degrees along the central axis, so that the main flow direction of the circulating water forms a new spatial geometric relationship with the flow surface of the ball collection mesh plate; for the fluid vortex zone and velocity stagnation zone formed inside the condenser water chamber, use solid filling blocks or guide cone components welded and fixed to the corner areas and internal cavities of the condenser water chamber, and perform comprehensive repair on the sealing components of the condenser water chamber partition area, reshaping the internal flow channel boundary.

[0025] By adopting the above technical solution, the installation angle of the ball-collecting net is redesigned to improve the condition of the water-facing surface and eliminate the dead zone of fluid vortex.

[0026] Preferably, the specific steps for conducting dynamic verification and economic benefit assessment of the condenser ball system are as follows: The flow rate during a single cycle is recorded using a ball counter installed in the pipeline of the condenser ball system; the absolute quantity of cleaning medium input and the absolute quantity of cleaning medium recovered during the single cycle are obtained; the absolute quantity of cleaning medium recovered by the control system is divided by the total quantity of newly added cleaning medium and the original cleaning medium input to the ball loading chamber in a single cycle to calculate the actual ball recovery rate parameter, thus completing the dynamic verification and economic benefit assessment of the condenser ball system; the condenser terminal differential reduction value recorded by the unit operation monitoring system is obtained, and the corresponding annual increase in power generation is calculated based on the unit thermal system efficiency calculation model, thus completing the overall economic benefit assessment of the condenser ball system's operating status.

[0027] By adopting the above technical solution, the ball collection rate can be quantitatively calculated in real time, and the economic benefit evaluation indicators of the system operation can be converted and output.

[0028] This invention provides a dynamic coordinated control method for improving the ball recovery rate of a condenser ball system. It has the following beneficial effects: 1. This invention establishes a complete technical system encompassing multiple levels, including dynamic coordinated adjustment at the operational level, refined management of condenser ball quality, sealing of internal structural defects in the condenser, and optimization of pipe and valve structures and auxiliary systems. By providing various intervention methods ranging from temporary adjustment of operating water flow dynamics to long-term modification of physical structures, application units can flexibly select corresponding combinations for local optimization or overall system upgrades based on the actual operating conditions and severity of problems in the condenser ball system, demonstrating high applicability and application value.

[0029] 2. This invention addresses the issue of condenser internal ball accumulation defects that are difficult to eliminate through conventional maintenance. It employs targeted physical sealing measures, including filling the top slots of titanium tubes with silicone structural sealant, sealing through-holes with closed-cell polyurethane foam, and adding nylon protective sleeves and rope net covers. These structural modifications eliminate stagnation points for the cleaning medium in mechanical gaps and structural pits, block the medium loss path in stagnant water zones, and ensure smooth movement of the cleaning medium. This reduces daily physical losses of the cleaning medium and significantly improves the system's average ball collection rate.

[0030] 3. The control method and optimization measures of this invention have significant comprehensive economic benefits. Management steps such as hydrodynamic adjustment and medium physical density screening can be implemented directly under normal unit operation, achieving low-cost intervention in the operation process; measures such as internal flow channel boundary reshaping and valve modification have short work cycles and are convenient to implement. The synergistic effect of these operations can save on the cost of daily cleaning media input for the system, reduce the time spent on manual inspection and maintenance, and effectively reduce the condenser terminal temperature difference by maintaining the cleanliness of the condenser piping network, thereby improving the overall efficiency of the generator unit's thermal system and the overall power generation output.

Detailed Implementation

[0032] The technical solutions in 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] See attached document Figure 1 The present invention provides a dynamic collaborative control method for improving the ball recovery rate of a condenser ball system, which may include the following steps: Step S100 involves performing dynamic coordinated adjustments at the operational level. In this step, the operating status of the pumps and the mechanical positions of valve components in the condenser ball cleaning system are acquired and intervened. The flow dynamics distribution within the pipeline is adjusted by changing the operating combination and timing of the circulating water pumps, while simultaneously mechanically locking the ball collection mesh plate to establish a tight physical enclosure. This step aims to eliminate cleaning medium retention caused by gas accumulation and ball leakage paths caused by mechanical clearances from the operational control end.

[0034] Step S200 involves implementing refined management of the quality and lifecycle of the cleaning media. In this step, the physical properties and lifecycle of the cleaning media introduced into the system are controlled. Standardized water immersion operations are used to ensure the cleaning media reaches the set volume expansion and density standards. Cleaning media with distinct color differences are used alternately, and based on the color ratio data difference obtained from the recovery point, structurally accumulating areas within the system are located. Simultaneously, periodic physical dimensional measurements are performed to remove media entities that have undergone geometric deformation or dimensional decay.

[0035] Step S300 involves targeted inspection and permanent sealing of internal structural defects in the condenser. In this step, specific physical filling and spatial sealing operations are performed on inherent geometric gaps and recessed areas within the condenser water chamber and piping valve bodies. By injecting curing sealing material or installing physical isolation mesh and protective kits, the surface flatness of localized areas is altered, blocking the physical movement trajectory of the cleaning medium into the stagnant water zone, thus eliminating mechanical jamming points at the physical structural level.

[0036] Step S400 involves comprehensive optimization of the pipe and valve structure and auxiliary systems. In this step, the internal flow field distribution of the condenser and the external pipe connection method are systematically reconstructed. Metal flow guide components are fixed at specific pipe cross-sections and mesh plate areas to alter the local velocity field distribution characteristics of the water flow and reduce the unilateral velocity difference. Simultaneously, auxiliary pipes for condition monitoring and one-way valve components to restrict reverse fluid flow are added to the piping system.

[0037] Step S500 involves selectively implementing a systemic upgrade based on long-term ball collection rate diagnostic results. This step is a condition-triggered step based on historical system operation data monitoring. When the absolute value of the system's ball collection rate is lower than a preset threshold, a spatial geometrical rotation and reorganization operation is performed on the ball collection net plate and its connecting pipes. The original support components in the low-flow-rate area are removed, and solid filling components are installed to reshape the geometric space of the internal water chamber.

[0038] Step S600 involves conducting dynamic verification of the effectiveness and economic benefit assessment of the ball-collecting system. In this step, the absolute quantities of cleaning media input and output during a single cycle are obtained using sensing equipment. Based on these quantity differences, the actual ball-collecting rate parameter is derived. Combined with imaging data of the internal physical structure acquired during system downtime, the residual quantity of cleaning media at each implementation node is compared to verify the physical effectiveness of the system's multi-level intervention operations.

[0039] See attached document Figure 1 The present invention provides a dynamic collaborative control method for improving the ball recovery rate of a condenser ball system, which may include the following detailed implementation steps.

[0040] In step S100, the main focus is on intervening in the operation status of the water pump equipment and the mechanical position of the valve components of the condenser ball cleaning system. This includes dynamic ball collection time control strategy, closed-loop confirmation mechanism for ball collection net tightness, dynamic monitoring and elimination of system defects, and daily maintenance operations for filter screen and water quality cleanliness.

[0041] When implementing the dynamic ball-collection time control strategy, the number and operating status of the circulating water pumps are acquired. When the system is operating with only one circulating water pump, the ball cleaning system is continuously run in ball-collection mode for two hours. After two hours of system operation, the second standby circulating water pump is started, and the two circulating water pumps run in parallel for thirty minutes. The operation of a single circulating water pump will cause a decrease in the fluid filling degree at the top of the condenser return water chamber and generate air accumulation, causing the cleaning medium to remain in the top space of the return water chamber. By starting the second circulating water pump in parallel, the water flow dynamics and velocity within the pipeline system are increased, the air accumulated at the top of the return water chamber is expelled, and the cleaning medium floating at the top of the water chamber is forced into the circulating fluid.

[0042] When implementing the closed-loop confirmation mechanism for the tightness of the ball-collecting net, the physical closure position of the ball-collecting net plate is checked before the ball-collecting system completes the ball-collecting procedure and enters the regular circulation mode. The control mode of the ball-collecting net plate is switched to manual mode via a mechanical transmission mechanism to perform a mechanical tightening operation. This controls the edge of the ball-collecting net to form a physical seal with the tube wall. This operation uses physical mechanical force to bring the ball-collecting net to a completely closed boundary position, blocking the physical movement path of the cleaning medium from flowing out through the mechanical gap between the ball-collecting net plate and the tube wall.

[0043] During dynamic monitoring and elimination of system defects, the integrity of the mechanical seal of the rubber ball pump within the system is checked. When damage to the mechanical seal component is detected, causing a drop in fluid output pressure, the mechanical seal is physically replaced to restore fluid delivery power. Simultaneously, the physical sealing status of the heating system's connecting pipelines is checked, and fluid leakage points on the pipeline surface are investigated. The location and status of drain valves distributed along the rubber ball system are obtained, drain valves in the open or semi-open state are closed, and internal leakage at the valve's internal flow surface when closed is detected. By eliminating internal and external leakage points in the system, leakage of fluid along with the cleaning medium is prevented.

[0044] During routine maintenance of the filter screen and water cleanliness, a fixed amount of diamond abrasive balls are added to the system according to the preset time cycle. The physical friction of the diamond abrasive surface scrapes away the deposits on the inner wall of the condenser titanium tubes. The physical concentration data of impurities in the circulating water is obtained. When the impurity concentration exceeds a preset threshold, the continuous operation mode of the fine filter screen is activated. At the media recovery end, a physical separation operation is performed on the intercepted mixed solid matter, separating the cleaning media from the impurities. This prevents non-standard impurities from adhering to the surface of the ball-collecting screen and clogging the flow pores, thereby maintaining the fluid permeability of the ball-collecting screen area.

[0045] See attached document Figure 1 The present invention provides a dynamic collaborative control method for improving the ball recovery rate of a condenser ball system, which may include the following detailed implementation steps.

[0046] In step S200, physical property control and status monitoring are mainly performed on the cleaning medium put into the system, including performing dynamic soaking operation of the rubber balls, controlling the density parameters of the cleaning medium, performing alternating use of two-color rubber balls and ball accumulation positioning analysis, and implementing dynamic screening and quantity replenishment of the rubber balls throughout their life cycle.

[0047] During the dynamic soaking operation of the cleaning media balls, a fixed-volume soaking container is installed outside the condenser equipment. A preset number of new cleaning media balls (500 balls) are placed inside the soaking container. The liquid level inside the soaking container is monitored at set intervals. When the liquid level is lower than the top of the cleaning media, fluid is injected into the soaking container so that all cleaning media are completely submerged below the fluid surface. The new cleaning media, in its fresh state, has not absorbed water, its physical dimensions are smaller than the standard working dimensions, and its material hardness parameter is higher than the standard working value. Before being put into the cleaning system, the new cleaning media is placed in warm water for a continuous soaking program, the duration of which is set to be greater than or equal to 24 hours. During the soaking process, the cleaning media absorbs fluid through its internal pores, causing its volume to expand and reach the set working physical dimensions. After absorbing water and expanding, the physical density of the cleaning media reaches the set range and is close to the physical density of the circulating cooling water.

[0048] When controlling the density parameters of the cleaning medium, the physical density data of a single cleaning medium is obtained, and the physical density parameter of the cleaning medium is limited to between 1.0 grams per cubic centimeter and 1.15 grams per cubic centimeter. Cleaning media with physical densities outside this limited range are discarded. Limiting the physical density of the cleaning medium is to prevent it from suspending in the top space of the condenser water chamber due to excessively low density, or from settling in the bottom area of ​​the condenser piping due to excessively high density, thereby ensuring that the cleaning medium maintains a normal movement trajectory under the influence of the fluid. At the same time, the physical properties of the cleaning medium are obtained, and cleaning medium that has exceeded its service life, undergone physical material hardening, or has physical damage on its surface is isolated and discarded, ensuring that the cleaning medium put into the system has the elastic deformation capacity required by the standard.

[0049] When performing alternating application and ball accumulation positioning analysis of dual-color cleaning balls, two cleaning media with first and second color attributes are obtained. During continuous system operation cycles, the first and second color cleaning media are alternately introduced into the system. At the media recovery end of the cleaning system, the absolute quantities of the first and second color cleaning media recovered in a single cycle are obtained. The quantity ratio data of the two color cleaning media are calculated. When the system is currently set to use the second color cleaning media, but the absolute quantity of the first color cleaning media obtained at the recovery end exceeds a preset benchmark value, it is determined that a physical release process of historically retained media has occurred inside the condenser pipeline. The time node data of the sudden increase in the quantity of the first color cleaning media is obtained, and combined with the fluid velocity parameters in the system pipeline, the physical distance from the media retention point to the recovery end is calculated, thereby locating the specific physical area of ​​the retained cleaning media inside the condenser.

[0050] When implementing dynamic screening and replenishment of cleaning media throughout the system's lifecycle, physical size measurements and geometric morphology checks are performed on the circulating cleaning media at set time intervals. The absolute physical diameter of each individual cleaning media is measured; if the detected physical diameter is less than a preset difference range for the condenser's inner tube diameter, the media is deemed to have experienced excessive physical wear. The appearance and geometric morphology of the cleaning media are obtained through visual or mechanical inspection to identify individuals with permanent geometric deformation or structural damage. Cleaning media identified as having excessive physical wear, geometric deformation, or structural damage are physically removed from the circulation system. The total number of qualified cleaning media remaining in the system after the removal operation is obtained, and the difference between this total number and the system's rated operating quantity parameter is compared. Based on the calculated quantity difference, a quantitative amount of new qualified cleaning media that has undergone a standard soaking process is added to the system to restore and maintain the total number of cleaning media in the system at the set rated level.

[0051] See attached document Figure 1The present invention provides a dynamic collaborative control method for improving the ball recovery rate of a condenser ball system, which may include the following detailed implementation steps.

[0052] In step S300, the physical gaps and recessed areas on the internal flow path of the condenser system are filled and spatially shielded. This includes micro-management of the grooves at the top of the titanium tubes, physical protection of the backflushing valve bolt gaps, composite management of the ball pits and holes in the valve volume, and physical deformation repair of the ball collection net and accessories.

[0053] When performing micro-treatment of the slot at the top of the titanium tube, a square slot with a width of 22mm and a depth of 10mm was physically sealed at the top of the titanium tube in the condenser circulating water inlet chamber. This square slot, under the pressure of the circulating water, traps the cleaning medium impacting it. The treatment involved filling the internal area with silicone structural sealant, which has a water flow impact resistance strength ≥1.5MPa and an operating temperature range of -40℃ to +200℃. The construction process included opening the condenser manhole with the power generation equipment shut down and removing any dirt or deposits from the square slot. Then, a high-pressure air gun was used to blow away the slot until no solid residue remained. The silicone structural sealant was then evenly injected into the slot using a caulking gun, controlling the filling depth to ≥8mm. After injection, a scraper was used to smooth the surface of the sealant, ensuring a surface flatness error ≤0.5mm, and the sealant was allowed to cure at room temperature for 24 hours. As an alternative to the above-mentioned glue injection filling solution, a 2mm thick 304 stainless steel sealing sheet can be used to cover the square groove, and the edges of the stainless steel sealing sheet can be fully welded and the welded surface can be physically polished.

[0054] When implementing physical protection for the bolt gaps of the backflushing valve, spatial isolation is performed on the fastening bolts distributed around the backflushing valve housing in the condenser inlet water chamber. The spatial gap between the bolt posts and the valve body in this area can obstruct the cleaning medium under fluid impact. The remedial measure is to install a 50mm outer diameter nylon protective sleeve on the outside of each bolt post. This nylon protective sleeve is made of PA66 material with a wall thickness of 2mm and a temperature resistance of up to 120℃. The nylon protective sleeve adopts a longitudinally split structural design and is equipped with a stainless steel clamp for external locking. The specific installation process includes first removing the original bolts and nuts and cleaning the surface of the bolt posts. Next, the split nylon protective sleeve is wrapped around the bolt post, and the nylon protective sleeve is closed using the stainless steel clamp and rigidly locked with a torque of 15 N·m. Finally, the removed nuts are reinstalled, and a no-loosening check is performed to ensure that the nylon protective sleeve is fixed in the designed position.

[0055] When performing a combined treatment of the spherical pit and holes in the valve body, the following spatial sealing is applied to the physical pit with a diameter of 1.2m and a depth ranging from 0.15m to 0.4m formed by the connecting valve in the condenser inlet and outlet water chamber structure, as well as the three through holes with a length of 0.6m formed by the valve reinforcing ribs. During circulation, the cleaning medium will accumulate inside the aforementioned physical pit and through holes along with the fluid flow direction. This combined treatment includes two specific physical operation measures. The first measure is to inject closed-cell polyurethane foam into the through holes formed by the valve body reinforcing ribs, with the physical density of the foam set at 35kg / m³. 3 The closed-cell ratio is ≥90%. After the foaming adhesive has fully cured, the portion extending beyond the pore surface is cut and leveled to eliminate dead zones in the flow field caused by the pores. The second measure is to install a quick-release nylon rope mesh cover above the physical recess at the top of the aforementioned connecting valve. This nylon rope mesh cover has a support frame made of 304 stainless steel, and its mesh size is set at 5mm×5mm. The support frame of the nylon rope mesh cover is fixed to the edge of the physical recess via a flange connection, preventing the cleaning medium from falling into the recess. At the same time, the flange connection structure allows for disassembly and internal cleaning operations during equipment maintenance.

[0056] When performing physical deformation repair on the ball-collecting net and its accessories, the structural dimensions and position calibration of the ball-collecting net system are performed during the power generation equipment maintenance cycle. The physical contact status between the ball-collecting net plate and the surrounding pipe wall is inspected. Physical deformation and weld detachment areas of the ball-collecting net plate are repaired through mechanical force application or metal welding, eliminating undesigned physical gaps between the ball-collecting net plate and the pipe wall to prevent physical escape of the cleaning medium from these gaps. Solid impurities inside the ball-collecting pipeline are removed using mechanical cleaning tools to restore the calibrated flow cross-sectional area of ​​the ball-collecting pipeline and ensure unobstructed physical flow of the medium recovery path. The stroke parameters of the electric actuator driving the ball-collecting net plate are recalibrated, and the limit control nodes of the electric actuator are adjusted to ensure that the ball-collecting net plate reaches the designed physical limit sealing position during the closing operation.

[0057] See attached document Figure 1 The present invention provides a dynamic collaborative control method for improving the ball recovery rate of a condenser ball system, which may include the following detailed implementation steps.

[0058] In step S400, structural modifications and flow field interventions are mainly performed on the physical pipes, valve components, and auxiliary hydraulic system of the ball ball system. This includes reconstructing the ball collection net guide component, adding a guide plate to the outlet bend section, adding auxiliary pipes and valves, and implementing hydraulic control for air accumulation treatment in the return water chamber.

[0059] When reconstructing the flow guiding components of the ball-collecting net, the original flow guiding components on the ball-collecting net plate are removed, and reconfigured flow guiding components are installed. The reconfigured flow guiding components generate turbulence in a designated local area of ​​the ball-collecting net plate, using hydrodynamics to guide the cleaning medium into the main water flow for continuous operation. Simultaneously, a vertical baffle is welded and fixed to the bottom of the ball-collecting net plate. The physical obstruction effect of the vertical baffle alters the fluid trajectory at the bottom of the ball-collecting net plate, adjusts the flow field distribution in this area, eliminates dead zones with excessively low flow velocities at the bottom, and prevents physical stagnation of the cleaning medium in the bottom region.

[0060] When adding guide plates to the outlet bend section, to address the asymmetrical flow field distribution caused by the structure within the condenser outlet bend section, metal guide plates are welded and added inside the bend section. These metal guide plates physically converge and guide the flow field of the medium passing through the bend section. This guiding and cutting operation reduces the deviation of the medium velocity on one side of the pipe, making the velocity distribution of the medium across the cross-section of the bend section more uniform. This uniform velocity distribution eliminates the unilateral accumulation of cleaning medium within the pipe, promoting a more even distribution of the cleaning medium and its impact on the collecting mesh plate with the water flow, thus reducing the probability of the cleaning medium escaping from the periphery of the collecting mesh plate.

[0061] When adding auxiliary pipelines and valves, an auxiliary test pipeline with a nominal diameter of DN80 is laid between the outlet of the ball loading chamber and the bend in the condenser outlet water pipe. This auxiliary test pipeline connects the two locations and provides an independent fluid testing channel during power generation equipment commissioning and fault diagnosis. Full-opening check valves are installed at the ball outlets of the A-side and B-side ball loading chambers of the power generation equipment. The internal valve disc structure of the full-opening check valves restricts the cleaning medium to flow unidirectionally from the ball loading chamber towards the condenser, physically blocking the reverse flow path of the cleaning medium. In addition, an optical or mechanical ball counter is fixedly installed on the system pipeline. The probe of this ball counter is connected to the medium recovery pipeline to acquire real-time data on the amount of cleaning medium passing through during a single recovery process and to calculate the real-time recovery ratio.

[0062] When implementing hydraulic control for air accumulation treatment in the return water chamber, a forced venting hydraulic regulation operation is performed to address the air accumulation at the top of the return water chamber caused by the lower inlet and upper outlet structure of the condenser circulating water system. When the monitoring system detects air accumulation at the top of the return water chamber, the control system sends a pump start command to activate the standby circulating water pump. After the standby circulating water pump is connected to the pipeline network, it provides additional hydraulic head and flow rate increment, driving the air accumulated at the top of the return water chamber to be forcibly discharged from the system pipeline network by high-speed water flow. After the accumulated air is discharged, the return water chamber returns to a full fluid state, eliminating the spatial environment where cleaning media are suspended and stagnant at the top of the return water chamber due to insufficient liquid level, ensuring that the cleaning media enters the normal circulation and recovery path.

[0063] See attached document Figure 1 The present invention provides a dynamic collaborative control method for improving the ball recovery rate of a condenser ball system, which may include the following detailed implementation steps.

[0064] In step S500, the data processing unit acquires historical recovery data within a set time period and calculates the average ball recovery rate. When the data processing unit determines that the average ball recovery rate is consistently below the threshold of 85%, it determines that there is flow field distortion and structural obstruction in the condenser ball system, and at this time, it outputs a systemic overall upgrade and modification command. This systemic overall upgrade and modification operation includes performing overall rerouting and optimized arrangement of the ball recovery net, as well as eliminating dead zones and reconstructing the internal structure of the condenser.

[0065] When performing the overall reversal and optimization of the ball-collecting net, all originally installed guide plates and fixed support components inside the condenser water chamber and related pipelines are physically removed to eliminate the physical interference of the original structural components on the flow field. Mechanical cutting and welding equipment is used to physically modify the installation interface of the ball-collecting net, spatially reversing the installation orientation of the entire ball-collecting net by 90 degrees along the central axis. This 90-degree spatial reversal changes the physical angle of the fluid impact on the ball-collecting net plate inside the pipeline, creating a new spatial geometric relationship between the mainstream flow direction of the circulating water and the flow surface of the ball-collecting net plate. Based on this, according to the hydrodynamic parameters after the reversal, a set number of guide components are re-welded onto the upper surface of the ball-collecting net plate, and vertical baffles are welded and installed at the bottom of the ball-collecting net plate.

[0066] When eliminating dead zones and reconstructing the internal structure of the condenser, solid filler blocks or guide cones made of corrosion-resistant metal are used to physically occupy the fluid vortex zones and velocity stagnation zones formed by abrupt structural boundary changes in the condenser's inlet and outlet water chambers. These solid filler blocks or guide cones are welded and fixed to the corner areas and internal cavities of the water chambers. By squeezing out ineffective fluid volume, the shape of the water chamber's internal boundary is reshaped, allowing the water flow to conform to the smooth flow channel boundaries after reconstruction. This physically eliminates dead zones where cleaning media stagnates or accumulates.

[0067] While reconstructing the internal flow channel boundaries, a comprehensive repair was performed on the sealing components in the condenser water chamber baffle area. Seals with physical deformation or material aging at the baffle joints were removed, and new high-elasticity seals were installed at the physical mating surfaces of the baffle edges. This seal repair operation sealed off undesigned crossflow channels between different pressure zones within the condenser water chamber, preventing the physical escape of cleaning media through baffle gaps. After completing the above seal repair, a metal welding process was simultaneously used to eliminate microscopic gaps between the edge of the ball-collecting mesh plate and the mounting pipe wall, creating a tightly bounded closed-loop media circulation system within the condenser ball system.

[0068] See attached document Figure 1 The present invention provides a dynamic collaborative control method for improving the ball recovery rate of a condenser ball system, which may include: In step S600, real-time data on the number of rubber balls is obtained by a rubber ball counter installed in the condenser rubber ball system pipeline to perform real-time calculation of the ball recovery rate. The rubber ball counter is either an optical or mechanical type, installed between the outlet of the ball loading chamber and the area above the bend in the condenser outlet water pipe. The control system receives pulse or digital signals transmitted from the rubber ball counter, records the number of rubber balls flowing through in a single cleaning cycle, and calculates the real-time ball recovery rate value based on the ball recovery rate calculation formula.

[0069] The formula for calculating the ball collection rate is: ; in, Indicates the real-time ball catch rate. This indicates the number of rubber balls recovered in a single operation, obtained by the control system through the rubber ball counter. This indicates the total number of newly added rubber balls and existing rubber balls added to the ball loading room in a single operation.

[0070] The control system will calculate the real-time ball collection rate. The data is stored in a database and compared with the set ball recovery rate evaluation criteria. The real-time ball recovery rate is calculated over a continuously set operating cycle. When the success rate is greater than or equal to 94%, the operating status of the ball-collecting system is determined to meet the set standard. At the same time, the control system compares historical ball collection rate data to verify whether the minimum single ball collection rate has increased from 40% to 86%, thereby quantifying the improvement index of the ball collection rate.

[0071] During the completion of the set operating cycle or unit shutdown maintenance phase, an endoscopic re-inspection of the condenser's internal ball accumulation is performed. Operators insert the probe of an industrial endoscope through the manhole or pre-reserved inspection hole into the condenser's inlet and outlet water chambers to acquire real-time image data of specific areas that have undergone structural sealing treatment. These specific areas include the 22mm wide and 10mm deep groove at the top of the titanium tubes, the gap between the bolt posts and the valve body around the backflushing valve housing, and the ball accumulation pits and reinforcing rib holes in the valve body. By comparing the image data with historical records, the number of physical balls in these areas is counted. When the image re-inspection results show that the ball accumulation rate in the titanium tube top groove is 0%, the bolt gap ball accumulation rate is 0%, and the valve body chamber ball accumulation rate is less than or equal to 3%, the physical sealing operation targeting the structural defects is deemed to have met the set technical indicators.

[0072] Based on the ball collection rate calculation data and endoscopic review results, the control system or data processing terminal performs a quantitative economic benefit assessment. It acquires the total ball consumption data for a specific statistical period and the historical total ball consumption data for the same period, calculating the difference in ball loss. For example, when the annual ball loss decreases from 1200 to 300, the specific cost savings are calculated based on the unit purchase price of a single ball, such as outputting a cost saving of 27000 CNY.

[0073] Simultaneously, condenser terminal temperature difference data recorded by the unit operation monitoring system is acquired, and the reduction in condenser terminal temperature difference is calculated. Under the condition that the system detects a 1.5℃ reduction in condenser terminal temperature difference, based on the unit's thermal system efficiency calculation model, the corresponding annual increase in power generation is calculated to be 1,200,000 kWh. Furthermore, maintenance man-hour data for cleaning accumulated balls inside the condenser is acquired from the unit maintenance management system. The current cycle's maintenance man-hours are compared with the historical average maintenance man-hours, outputting a reduction of 200 h / yr, thus completing the overall economic benefit quantitative assessment of the condenser ball system's operating status.

[0074] Specific application examples: See attached document Figure 2 The present invention provides a dynamic collaborative control method for improving the ball collection rate of a condenser ball system, which may include the following specific application steps.

[0075] Raw operating data was obtained using Unit 3 of a power plant as the implementation subject. Operational records show that after historical modifications, the unit's ball recovery rate was stable between 85% and 95%. After long-term operation, the ball recovery rate decreased to between 60% and 70%, with single-cycle ball recovery rates fluctuating between 40% and 95%. Physical inspection data obtained during shutdown and opening of the condenser cover showed 23 balls stuck in a 22mm wide and 10mm deep groove at the top of the titanium tube in the condenser inlet water chamber. 15 balls were found stuck in the bolt gaps around the backflushing valve housing. 86 balls were found stuck in the valve body cavity formed by the ball pits and reinforcing rib holes. The unit's material log records an annual ball loss of 1200 balls.

[0076] The control system outputs control commands to adjust system parameters. The initial ball collection time under single-circulation pump operation is set to 2 hours. After this time parameter is reached, the standby circulating pump is started and runs in parallel for 30 minutes. The operator performs a physical verification to confirm that the ball collection net is in the fully closed position and performs a manual tightening action. Under summer conditions with high impurity levels in the circulating water, the control system outputs signals to maintain continuous operation of the fine filter. The unit is equipped with a dedicated soaking container and filled with a specified volume of water to ensure that 500 balls have a density of 1.0 g / cm³. 3 Up to 1.15 g / cm 3The rubber balls in the designated area are fully submerged. Red and blue rubber balls are used alternately, and any balls that have undergone physical deformation are discarded.

[0077] Physical sealing was implemented at the location of structural defects. Silicone structural sealant was used to fill the top groove of the titanium tube, which was 22mm wide and 10mm deep. Twelve nylon protective sleeves were added to the outside of the bolted posts around the backflushing valve housing in the inlet chamber and secured with stainless steel clamps. Polyurethane foam was injected into the through-holes formed by the valve body reinforcing ribs to perform closed-cell filling. A nylon rope mesh cover with a mesh size of 5mm x 5mm was installed at the valve top recess using a flange connection. The original flow guiding components of the ball-receiving mesh plate were removed and a flow distribution plate was re-welded. A metal baffle plate was welded vertically to the bottom of the ball-receiving mesh plate. A metal flow guide plate was welded to the inner wall of the condenser outlet bend section. A full-opening check valve was installed at the ball-loading chamber outlet pipe. An optical ball counter was installed on the main return water pipe to transmit digital pulse signals to the control system.

[0078] Based on the above physical structure reconstruction and operational parameter adjustment, the execution formula parameters are calculated. The optical ball counter obtains the number of balls flowing through during a single cleaning cycle. The control system calculates the real-time ball recovery rate based on this number. The formula for calculating the ball recovery rate is:

[0079] Combination Figure 2 The simulation data shown indicates that the control system is set to add a total of 500 new rubber balls to the loading chamber in a single operation, equal to the total number of existing rubber balls. The control system collects data over 30 consecutive operating cycles. Figure 2 As shown, in the 5th operating cycle, the control system received a signal from the ball counter recording 470 balls recovered in a single run. Substituting this into the aforementioned calculation formula, the real-time ball recovery rate was 94%. The 12th operating cycle saw the lowest real-time ball recovery rate, with the control system recording 430 balls recovered in a single run. Substituting this into the formula, the real-time ball recovery rate was 86%. The real-time ball recovery rates for the remaining operating cycles fluctuated between 86% and 97%, generally distributing around a baseline value of 94%.

[0080] Experimental verification and effect comparison: See attached document Figure 3 To verify the physical execution results and parameter changes of this scheme, the control system performs experimental verification and effect comparison steps.

[0081] Endoscopic image comparison results showed that the number of physically stuck balls in the groove at the top of the titanium tube decreased from 23 to 0, and the corresponding ball accumulation rate decreased from 100% to 0%. The number of physically stuck balls in the bolt gap decreased from 15 to 0, and the corresponding ball accumulation rate decreased from 85% to 0%. The number of physically stuck balls in the valve body chamber decreased from 86 to 3, and the corresponding ball accumulation rate decreased from 92% to 3%. Figure 3 The displayed comparative data bar chart shows that the system's annual average ball collection rate was 68% before implementation, which increased to 94% after implementation. The system's lowest single ball collection rate was 40% before implementation, which increased to 86% after implementation. Unit material ledger data shows that the annual ball loss decreased from 1200 to 300. Based on the ball purchase price stored in the system, the calculated cost saving for balls is 27,000 CNY. The unit maintenance management system records a 200-hour / year reduction in physical operation time for cleaning accumulated balls inside the condenser. The unit operation monitoring system detected a 1.5°C decrease in the condenser terminal temperature difference parameter. Based on the thermal efficiency calculation model, this terminal temperature difference data outputs an annual increase in power generation of 1,200,000 kWh. The above data collection, comparison, and calculations validated the control method.
