However, this system connects multiple cooling walls of the blast furnace in series for closed-loop cooling. Typically, each cooling wall layer of a blast furnace has more than 50 sections, and each cooling wall has 4-5 front-row pipes, with more than 200 sets of soft water cooling pipes connected in series, resulting in an extremely complex on-site piping layout. In addition, the high dust and humidity levels on-site make maintenance very difficult after long-term use of various facilities. Especially in the middle and later stages of blast furnace operation, the cooling walls are prone to damage, and checking for leaks presents many challenges.

[0003] Currently, leak inspection of blast furnace cooling walls mainly relies on manual labor, with common methods including flow meter methods, ignition and gas measurement methods, and pipeline pressure testing. In actual inspections, these methods often need to be used in combination. However, these traditional methods are not only cumbersome to operate, but also have a significant impact on the service life of the cooling walls, making it difficult to meet the requirements for efficient and stable operation of blast furnaces.

[0021] Compared with the prior art, the advantages of this application are:

[0022] The leakage detection device described in this application is used for leakage detection in a blast furnace soft water system. The device includes a detection pipeline, a flow meter, a thermometer, a pressure gauge, and a processor. The detection pipeline is connected in series with a soft water cooling pipe and has a first end and a second end. Fluid in the soft water cooling pipe enters the detection pipeline from the first end and flows back to the soft water cooling pipe from the second end. The flow meter is located in the middle of the detection pipeline and is used to detect the flow rate of the fluid flowing from the first end to the second end, and outputs a flow rate signal.

This improves the accuracy and efficiency of the inspection. Traditional inspection methods, such as pipeline pressure testing, can apply additional pressure to the cooling walls, further shortening their lifespan. Attached Figure Description

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is intended to aid in understanding the present invention, but does not constitute a limitation thereof. The specific structural and functional details disclosed herein are only for describing exemplary embodiments of the present invention. However, the present invention may be embodied in many alternative forms and should not be construed as being limited to the embodiments described herein.

[0029] like Figure 1 As shown, Figure 1 This is a schematic diagram of a water leakage detection device provided in an embodiment of this application; a water leakage detection device for a blast furnace soft water system, the water leakage detection device including a detection pipeline 100, a flow meter 200, a thermometer 300, a pressure gauge 400, and a processor, wherein:

[0030] like Figure 1 As shown, the detection pipeline 100 is used to connect in series with the soft water cooling pipe. The detection pipeline 100 has a first end 101 and a second end 102. The fluid in the soft water cooling pipe can enter the detection pipeline 100 from the first end 101 and flow back to the soft water cooling pipe from the second end 102.

[0031] like Figure 1 As shown, the detection pipeline 100 is connected in series with the blast furnace soft water cooling pipeline, serving both as a diversion and detection function. The detection pipeline 100 has a first end 101 and a second end 102. Fluid in the cooling pipeline enters the detection pipeline 100 from the first end 101, and after undergoing a series of tests, flows back to the cooling pipeline from the second end 102. This not only ensures the normal operation of the cooling system but also provides an independent channel for detection.

[0032] The detection line 100 ensures smooth and uniform fluid flow. The inner wall of the detection line 100 is kept smooth to effectively reduce fluid resistance and prevent impurity deposition, thereby ensuring the stability and accuracy of the detection signal.

[0033] like Figure 1As shown, the flow meter 200 is located in the middle of the detection pipeline 100. The flow meter 200 is used to detect the flow rate of the fluid flowing from the first end 101 to the second end 102 and outputs a flow signal.

[0034] Flow meter 200 is installed in the middle of the detection pipe 100 for real-time monitoring of fluid flow. The working principle of flow meter 200 is based on the continuity equation and Bernoulli's equation in fluid mechanics. When fluid passes through the detection pipe 100, flow meter 200 calculates the volumetric flow rate per unit time by measuring the fluid velocity and cross-sectional area. Flow meter 200 accurately detects minute changes in flow rate and converts them into an electrical signal output.

[0035] In blast furnace soft water cooling systems, flow rate changes are a crucial indicator for leak detection. Under normal circumstances, the cooling water flow rate should remain relatively stable. If an abnormal flow rate is detected, during actual testing, a range of 1-3% can be set as the normal fluctuation range. If the flow rate exceeds this range, a leak in the cooling pipe is identified, causing cooling water to leak through the leak and resulting in a change in flow rate in the detection pipe 100. The high precision and real-time monitoring capability of the flow meter 200 enable the leak detection device to quickly detect this change, providing crucial information for subsequent leak assessment.

[0036] like Figure 1 As shown, a thermometer 300 is located in the middle of the detection pipeline 100. The thermometer 300 is used to detect the temperature of the fluid flowing from the first end 101 to the second end 102 and output a temperature signal.

[0037] Thermometer 300 is also installed in the middle of the detection line 100 to monitor changes in fluid temperature. The thermometer 300 operates based on thermodynamic principles, reflecting the heat exchange status of the cooling system by measuring the fluid temperature. The thermometer 300 uses a thermistor, enabling it to accurately detect minute changes in fluid temperature and convert them into an electrical signal output.

[0038] In blast furnace cooling systems, the temperature change of cooling water is closely related to heat transfer. When water leaks from the cooling wall, the cooling water undergoes additional heat exchange with the surrounding environment, causing temperature changes. For example, if the cooling water comes into contact with the high-temperature furnace wall through the leak, its temperature may rise; conversely, if the cooling water comes into contact with the low-temperature external environment, its temperature may drop. Thermometer 300 monitors temperature changes in real time, and when temperature fluctuations exceed a set range, it provides another important parameter for leak detection. Combined with flow signals, the temperature signal can further improve the accuracy and reliability of leak detection.

[0039] like Figure 1As shown, the pressure gauge 400 is located in the middle of the detection pipeline 100. The pressure gauge 400 is used to detect the pressure in the detection pipeline 100 and output a pressure signal.

[0040] Pressure gauge 400 is installed in the middle of detection line 100 to monitor pressure changes within the line. The working principle of pressure gauge 400 is based on the pressure transmission principle in fluid mechanics. When fluid flows in detection line 100, pressure gauge 400 measures the fluid pressure to reflect the pressure state of the cooling system. Pressure gauge 400 uses a pressure sensor, which can accurately detect minute pressure changes and convert them into an electrical signal output.

[0041] In blast furnace cooling systems, pressure changes are a crucial indicator for leak detection. Under normal circumstances, the cooling water pressure should remain relatively stable. An abnormal pressure drop may indicate a leak in the cooling pipes, causing water loss and pressure reduction. The pressure gauge 400 enables leak detection devices to quickly detect such changes, providing vital information for subsequent leak assessment. Combined with flow and temperature signals, the pressure signal further enhances the accuracy and reliability of leak detection.

[0042] The processor is connected to the flow meter 200, the thermometer 300 and the pressure gauge 400 respectively, and the processor receives and processes the flow signal, the temperature signal and the pressure signal.

[0043] The processor is connected to the flow meter 200, thermometer 300, and pressure gauge 400 respectively, and performs comprehensive analysis and processing on the flow, temperature, and pressure signals. By setting reasonable thresholds and logical relationships, the processor can determine whether there is a leak in the cooling system and issue an alarm in a timely manner.

[0044] The processor operates based on multi-parameter comprehensive analysis. When any parameter—flow rate, temperature, or pressure—changes abnormally, the processor combines this information with changes in other parameters to make a comprehensive judgment. For example, if the flow rate increases while the temperature and pressure remain constant, it might be a fluctuation in the normal operation of the cooling system; however, if the flow rate increases along with abnormal changes in temperature and pressure, the processor will determine that there is a leak and issue an alarm. This multi-parameter comprehensive analysis method effectively reduces false alarms and improves the accuracy and reliability of leak detection.

[0045] Traditional manual inspection methods are inefficient and can easily damage the cooling walls, shortening their lifespan. This leak detection device collects flow rate, temperature, and pressure data, and the processor quickly analyzes the data, avoiding subjective errors associated with manual inspection and improving the accuracy and efficiency of detection.

[0046] The blast furnace cooling system has a complex piping layout, making it difficult for traditional detection methods to quickly locate leaks. This leak detection device connects detection pipes 100 in series with the cooling pipes and uses the combined changes in flow rate, temperature, and pressure to determine the location of leaks. It can quickly and accurately locate leaks and works effectively even in complex piping layouts.

[0047] As blast furnaces enter their later stages of operation, the cooling walls are prone to damage due to prolonged use, increasing the difficulty of leak detection. This leak detection device monitors minute changes in flow rate, temperature, and pressure, enabling timely detection of even minor damage to the cooling walls. This prevents further damage caused by leaks and extends the service life of the cooling equipment.

[0048] Traditional leak detection methods, such as pipeline pressure testing, can impose additional pressure on the cooling walls, shortening their lifespan. This leak detection device uses a non-destructive testing method, which will not damage the cooling walls, effectively protecting the cooling equipment and extending its service life.

[0049] In an optional embodiment, the leakage detection device of this application is applied to leakage detection operations in a blast furnace soft water system. The leakage detection device includes a detection pipeline 100, a flow meter 200, a thermometer 300, a pressure gauge 400, and a processor. The detection pipeline 100 is connected in series with a soft water cooling pipe. The detection pipeline 100 has a first end 101 and a second end 102. Fluid in the soft water cooling pipe can enter the detection pipeline 100 from the first end 101 and flow back to the soft water cooling pipe from the second end 102. The flow meter 200 is located in the middle of the detection pipeline 100 and is used to detect leakage from the first end 101. The flow rate of fluid flowing from one end 101 to the second end 102 is measured and a flow rate signal is output. A thermometer 300 is located in the middle of the detection pipe 100. The thermometer 300 is used to detect the temperature of the fluid flowing from the first end 101 to the second end 102 and outputs a temperature signal. A pressure gauge 400 is located in the middle of the detection pipe 100. The pressure gauge 400 is used to detect the pressure in the detection pipe 100 and outputs a pressure signal. A processor is connected to the flow meter 200, the thermometer 300, and the pressure gauge 400 respectively. The processor receives and processes the flow rate signal, the temperature signal, and the pressure signal.

[0050] The leak detection device can simultaneously detect three key indicators: flow rate, temperature, and pressure. Compared to single-parameter detection methods, it can more comprehensively and accurately determine the leak situation, reduce false alarms, and improve detection reliability. Secondly, the detection pipeline is connected in series with the soft water cooling pipeline, which does not affect the normal operation of the blast furnace. It enables real-time online monitoring of the cooling system. By analyzing fluctuations in the detection results, potential leaks can be detected in a timely manner, avoiding equipment damage and production accidents caused by delayed detection. Furthermore, the processor receives and processes flow rate, temperature, and pressure signals without frequent manual intervention, reducing the workload and error of manual detection and improving detection efficiency. The device can also quickly and accurately locate leak points, facilitating timely repair measures, reducing the risk of cooling wall damage, and extending equipment lifespan. The leak detection device can adapt to harsh environments such as high dust and humidity at the blast furnace site, and its installation and maintenance are relatively simple, making it suitable for long-term stable operation.

[0051] Traditional manual inspection methods are inefficient and can easily damage the cooling walls, shortening their lifespan. Leak detection devices collect flow, temperature, and pressure data in real time, avoiding subjective errors associated with manual inspection and preventing further damage to the cooling walls due to leaks. This improves the accuracy and efficiency of the inspection. Traditional inspection methods, such as pipeline pressure testing, can apply additional pressure to the cooling walls, further shortening their lifespan.

[0052] like Figure 1 As shown, in an optional embodiment, the detection pipeline 100 is further provided with a water tank 500 in the middle, the water tank 500 is provided with a first inlet 501 and a first outlet 502 connecting the detection pipeline 100, and the top of the water tank 500 is also provided with a second outlet 503 for venting.

[0053] A water tank 500 is also provided in the middle of the detection pipeline 100 to further optimize the detection process. The water tank 500 is connected to the detection pipeline 100 through a first inlet 501 and a first outlet 502. Cooling water can flow from the detection pipeline 100 into the water tank 500, stay briefly, and then flow out of the water tank 500 to return to the cooling pipeline. This not only provides a buffer space for the cooling water but also effectively stabilizes the fluid state within the detection pipeline 100, reducing the impact of fluid turbulence or pressure fluctuations on detection accuracy. In addition, a second outlet 503 is provided at the top of the water tank 500, specifically for venting. When cooling water flows into the water tank 500, it may carry a small amount of air or other gases. If these gases are not vented in time, they may accumulate in the water tank 500, affecting the accuracy of the detection. By providing an vent, the smooth discharge of gases from the water tank 500 can be ensured, maintaining the stable operation of the detection system.

[0054] like Figure 1As shown, in an optional embodiment, the second outlet 503 is equipped with an exhaust valve 601. The function of the exhaust valve 601 is to control the gas discharge process, making it more orderly and controllable. During the operation of the detection system, the exhaust valve 601 can be opened automatically or manually as needed to discharge the gas in the water tank 500. This not only prevents the pressure rise caused by gas accumulation, but also avoids the formation of bubbles in the water tank 500, thereby reducing interference with the fluid detection signal. For example, at the initial stage of system startup, when the cooling water enters the water tank 500, it may carry a large amount of air. At this time, the exhaust valve 601 can be opened quickly to discharge the air, ensuring that the water tank 500 is filled with cooling water as soon as possible and enters a stable operating state.

[0055] like Figure 1 As shown, in an optional embodiment, the second outlet 503 is provided with a detector 602 for detecting carbon monoxide content.

[0056] A carbon monoxide detector 602 is also installed at the second outlet 503. During operation, damage or leaks in the cooling walls of the blast furnace cooling system may cause cooling water to come into contact with the high-temperature environment inside the furnace, potentially generating harmful gases such as carbon monoxide. By installing the carbon monoxide detector 602 at the exhaust port of the water tank 500, the carbon monoxide content in the exhaust gas can be monitored in real time. Once an abnormally high carbon monoxide concentration is detected, it may indicate a leak in the cooling system, with cooling water coming into contact with the high-temperature environment inside the furnace. This not only provides additional information for leak detection but also allows for the timely identification of potential safety hazards, ensuring the safe operation of the blast furnace.

[0057] like Figure 1 As shown, in an optional embodiment, the first outlet 502 is located at the bottom of the water tank 500, and the first inlet 501 is located on the side wall of the water tank 500. This fully utilizes gravity, allowing cooling water to flow more smoothly into the water tank 500 and to mix and stabilize thoroughly within it. When cooling water flows into the water tank 500 from the first inlet 501 on the side wall, the flow rate rapidly decreases, and the water flow becomes more stable. Subsequently, the cooling water flows out from the first outlet 502 at the bottom of the water tank 500 and re-enters the detection pipeline 100. This not only helps reduce the impact of water flow on the bottom of the water tank 500 but also ensures a more stable state of the cooling water flowing out of the water tank 500, thereby improving the accuracy of the detection.

[0058] like Figure 1As shown, in an optional embodiment, the volume of the water tank 500 is 2–5 m³. This volume range has been carefully calculated and optimized to balance detection accuracy and system operating efficiency. If the volume of the water tank 500 is too small, it may not be able to effectively stabilize the fluid state, leading to interference with the detection signal; while if the volume of the water tank 500 is too large, it will increase the complexity and cost of the system, and also reduce the system's response speed. A volume of 2–5 m³ provides sufficient buffer space for the cooling water to ensure the stability of the detection signal without negatively impacting the overall operating efficiency of the system. In addition, this volume range can accommodate blast furnace cooling systems of different sizes, exhibiting good versatility and adaptability.

[0059] like Figure 1 As shown, in an optional embodiment, the thermometer 300, the pressure gauge 400, and the flow meter 200 are sequentially arranged between the first end 101 and the water tank 500. This arrangement is based on optimized detection process considerations. When cooling water enters the detection pipeline 100 from the soft water cooling pipe, it first passes through the flow meter 200, which can monitor the flow rate changes of the cooling water in real time. Subsequently, the cooling water continues to flow, passing through the thermometer 300 and the pressure gauge 400, which detect the temperature and pressure respectively. This sequential arrangement ensures that all key parameters are detected one by one before the cooling water enters the water tank 500, providing complete data support for subsequent comprehensive analysis. In addition, this arrangement can reduce mutual interference between detection devices and improve the accuracy and reliability of detection signals.

[0060] like Figure 1 As shown, in an optional embodiment, a water inlet valve 603 is provided between the first end 101 and the thermometer 300. The main function of the water inlet valve 603 is to control the flow rate and timing of cooling water entering the detection pipeline 100. During the operation of the detection system, the water inlet valve 603 can be adjusted as needed. For example, when the system starts or stops, the water inlet valve 603 can be closed to cut off the flow of cooling water and protect the detection equipment from impact. In addition, the water inlet valve 603 can also play an important role if fine-tuning of the cooling water flow rate is required during the detection process. By precisely controlling the water inlet flow rate, the stability and consistency of the detection signal can be ensured, thereby improving the accuracy of the detection.

[0061] like Figure 1As shown, in an optional embodiment, an outlet valve 604 is provided between the water tank 500 and the second end 102. The function of the outlet valve 604 is to control the flow rate and timing of cooling water flowing out of the water tank 500. In conjunction with the inlet valve 603, the outlet valve 604 can be adjusted as needed to ensure the stability of the fluid state within the detection pipeline 100. For example, during system operation, if it is necessary to replace or clean the cooling water in the water tank 500, the flow of cooling water can be temporarily stopped by closing the outlet valve 604. Furthermore, the outlet valve 604 can also work in conjunction with the inlet valve 603 to achieve precise control of the fluid pressure and flow rate within the detection pipeline 100 by adjusting the inlet and outlet flow rates, further improving the accuracy and reliability of the detection.

[0062] In an optional embodiment, the cross-sectional area of ​​the detection pipe 100 is larger than that of the soft water cooling pipe. This reduces the flow velocity of the cooling water in the detection pipe 100, thereby reducing the impact of water flow on the detection equipment and improving the stability of the detection signal. When cooling water enters the detection pipe 100 from the soft water cooling pipe, the flow velocity decreases rapidly due to the increased cross-sectional area, and the water flow becomes more stable. This not only helps reduce wear on the detection equipment but also reduces signal interference caused by fluid turbulence. Furthermore, the larger cross-sectional area provides more buffer space for the cooling water, further stabilizing the fluid state and improving the accuracy of the detection.

[0063] In actual configuration, the cross-sectional area of ​​the detection pipeline 100 is 1.2 to 1.5 times that of the soft water cooling pipeline.
