Description

Technical Field

[0001] The present invention relates to the field of heat exchange technology, and in particular to a device for repairing heat exchange tube leakage. Background Art

[0002] Leakage in heat exchangers for heating units has long been a major concern for the safe operation of power plants. When a heat exchanger leaks, the condensate becomes contaminated. In most power plants, condensate returns to the deaerator after heat exchange. Leakage in the heat exchanger deteriorates the water vapor quality of the feedwater system, causing corrosion and scaling in the thermal system, seriously threatening the safe operation of the unit.

[0003] The existing heat exchanger stations of heating units are not equipped with any leak detection equipment. Only when the water vapor indicators of the water supply system are unqualified, manual sampling is carried out through the on-site sampling valve of the heat exchanger, and the leaks are analyzed and eliminated one by one. After the leaking heat exchanger is found, it is decoupled or discharged, or a detection vehicle is used for detection. However, due to the uneven ground environment, the detection vehicle has difficulty moving and cannot arrive effectively.

[0004] Secondly, common problems with manual inspections to eliminate heat exchanger leaks include: 1) Leak detection is not carried out in a timely manner. Leak detection is only performed after the water quality in the water supply system has deteriorated, which has already caused corrosion and scaling in the thermal system. 2) Safety risks are high. The condensate temperature after heat exchange is generally around 90°C, and manual sampling on-site poses a risk of burns. 3) Sampling is poorly representative. The on-site sampling valve is always closed, and opening it for a short period of time to take a sample cannot completely flush out any remaining corrosion products in the pipeline. Furthermore, manual sampling results in large measurement errors, which can easily lead to misjudgments and false positives.

[0005] For example, Patent No. 201910693847.5 discloses an online diagnostic device and method for heat exchanger tube leakage in a heating unit. This device adds a sampling point at the condensate outlet of each heat exchanger, performs independent sampling and measurement, and uses an intelligent diagnostic system to monitor the operating status of the heat exchanger in real time. When a heat exchanger leaks, it can accurately and immediately determine which heat exchanger is leaking. Although this method can locate the leak point, it cannot effectively detect large pressure and temperature fluctuations inside the heat exchanger tube. Summary of the Invention

[0038] Example description; Data collection layer (real-time perception) Parameter acquisition unit Deploy pressure / temperature sensors inside the heat exchange tube 1 to monitor fluid parameters in real time; Calculate the rate of change of key indicators (e.g., pressure fluctuation rate = ΔP / Δt, temperature gradient = ΔT / tube length).

[0039] Detection unit Set up detection points at key nodes of the pipeline (elbows, welds, etc.) to capture abnormal signals (such as: characteristic frequency of acoustic leakage, flow rate mutation).

[0040] Image acquisition component 4 The lifting component 3 carries a high-definition camera to scan cracks or corrosion areas on the pipe wall surface and generate thermal imaging / visible light images.

[0041] Output: Original data set = {pressure value, temperature value, rate of change, image features, abnormal signal} Fault diagnosis layer (local analysis) Fault Analysis Unit Input: Fault instructions generated by the detection unit (e.g., "Node 7 traffic suddenly dropped 30%").

[0042] Processing logic: Python If the pressure fluctuation rate > threshold K1: Classified as "Excessive pressure fluctuation" (second warning) elif image recognition detects crack OR acoustic wave frequency ∈ [leakage frequency band]: Classified as "Pipeline Wall Rupture" (First Warning) else: Launch a deep learning model (training data: historical leakage cases) for secondary diagnosis.

[0043] Classification alarm unit Generate graded warnings: First warning (emergency): Pipe wall rupture → Trigger repair components to standby; Second warning (warning): Pressure fluctuation → adjust system operating parameters.

[0044] Model building layer (trend forecasting) Model building unit Build a fault evolution model based on real-time data streams: Time series analysis: pressure / temperature change rate → predict leakage risk probability (e.g. ARIMA algorithm); Spatial correlation analysis: multiple detection point data → locate the leak point coordinates (triangulation positioning method); Image semantic segmentation: marking crack propagation paths (UNet algorithm).

[0047] processing unit Generate the final instruction: Confirm the leak → Control the walking / lifting component 3 to move to the coordinate (X, Y) and start repairing the component (e.g., injecting sealant); False positive → record learning samples and update local algorithm.

[0049] 1. Data layer: Parameter unit → Detected pressure fluctuation rate of 0.8MPa / s (exceeding threshold value 0.5); Detection unit → Acoustic sensor captures 30kHz frequency band leakage characteristic wave; Image unit → A 2mm crack was found on the pipe wall near T7.

[0050] 2. Diagnostic layer: Fault analysis unit → Comprehensively judged as "pipe wall rupture" (first warning); Model element → predicts that the crack will grow to the critical value within 2 hours.
