Abstract
Description
Technical Field
[0001] This application belongs to the field of steam target technology, and in particular relates to a steam target detection system and detection method. Background Technology
[0002] In marine nuclear power systems, ensuring system cleanliness is a crucial aspect of guaranteeing the safe and stable operation of the entire vessel. Among these, the cleanliness control of the steam system is particularly important, and its cleaning process is the most complex. During the steam system cleaning process, steam target testing is required to verify whether the pipeline cleanliness meets the process standards.
[0003] However, the steam target testing system of this technology has significant efficiency problems: after the first target test, when replacing the target plate for the second test, the boiler room must be shut down to stop the steam supply, and steam supply can only be resumed after the target plate is replaced. Due to the excessively long steam supply pipeline, it takes a considerable amount of time to restore the high-temperature steam to the required flow rate and temperature, which severely affects the efficiency of steam cleaning. Furthermore, if the target plate is not properly sealed during replacement, high-temperature steam leakage may occur, causing burns to personnel. Summary of the Invention

The entire target testing process does not require stopping the steam supply, which can significantly improve the efficiency of target testing and avoid high-temperature steam leakage, reducing the risk of burns and thus improving safety.
[0005] In a first aspect, this application provides a steam target detection system, comprising: Main pipeline; The target plate mounting section is located on the main pipeline and is used to install the target plate assembly. The target plate mounting section divides the main pipeline into a first branch pipeline and a second branch pipeline. A bypass pipe is connected to both ends of the target plate mounting section, and both ends of the bypass pipe are respectively connected to the first branch pipe and the second branch pipe. A conversion component is used to switch the connection between the first branch pipe and the target plate mounting section or the bypass pipe.
[0006] In some embodiments, the switching assembly includes a first shut-off valve and a second shut-off valve; the first shut-off valve is disposed in the target plate mounting section for connecting or disconnecting the target plate mounting section from the first branch pipe; the second shut-off valve is disposed in the bypass pipe for connecting or disconnecting the bypass pipe from the first branch pipe.
[0007] In some embodiments, the steam target detection system further includes a drain pipe connected to the target plate mounting section; a drain valve is provided on the drain pipe for cutting off or connecting the drain pipe.
[0008] In some embodiments, the target plate assembly includes a target plate holder and a target plate, the target plate being detachably connected to the target plate holder; the target plate holder is fixedly connected to the main pipeline to maintain the target plate in a stationary state when the target plate is subjected to steam impact.
[0009] In some embodiments, the steam target detection system further includes: The controller, which is communicatively connected to the conversion component, is configured to: upon receiving a target firing signal, control the conversion component to switch states so that the target plate mounting section is connected to the first branch pipe; Upon receiving a target plate replacement signal, the conversion component is controlled to switch states so that the bypass pipe is connected to the first branch pipe.
[0010] In some embodiments, the controller is also configured to open the drain valve upon receiving a target plate replacement signal.
[0011] In some embodiments, the steam target detection system further includes a drive pump, which is located at the steam inlet end of the main pipeline and is used to adjust the steam delivery rate. The controller is also configured to: upon receiving the target firing signal, control the drive pump to drive steam to be transported in the pipeline at a first rate; Upon receiving the target plate replacement signal, the drive pump is controlled to drive steam to be transported in the pipeline at a second rate, wherein the second rate is less than the first rate.
[0012] Secondly, this application provides a steam target testing method, applied to the steam target testing system described in the first aspect, the steam target testing method comprising: In response to the target firing signal, the conversion component is controlled to switch to a first state so that the first branch pipe is connected to the target plate mounting section; In response to a target plate replacement signal, the conversion component is controlled to switch to a second state so that the first branch pipe is connected to the bypass pipe.
[0013] In some embodiments, the switching assembly includes a first shut-off valve and a second shut-off valve; the first shut-off valve is disposed in the target plate mounting section for connecting or disconnecting the target plate mounting section from the first branch pipe; the second shut-off valve is disposed in the bypass pipe for connecting or disconnecting the bypass pipe from the first branch pipe. The control of switching the conversion component to the first state specifically includes: controlling the first shut-off valve to open and controlling the second shut-off valve to close; The control of switching the conversion component to the second state specifically includes: controlling the first shut-off valve to close and controlling the second shut-off valve to open.
[0014] In some embodiments, the steam target detection system further includes a drive pump, which is located at the steam inlet end of the first branch pipe and is used to adjust the steam delivery rate.

[0015] The steam target firing detection system of this application, when conducting target firing tests, switches the connection between the first pipeline and the target plate installation section via a conversion component, allowing steam to enter the target plate installation section instead of the bypass pipeline, thus enabling normal target firing. When the target plate needs to be replaced, the conversion component switches the connection between the first pipeline and the bypass pipeline, allowing steam to enter the bypass pipeline instead of the target plate installation section. This means that target plate replacement does not require shutting down the steam equipment or stopping the steam supply; the entire main pipeline remains filled with high-temperature steam. Therefore, target firing tests can be performed immediately after target plate replacement without waiting, thereby improving target firing efficiency and consequently, the efficiency of steam cleaning. Furthermore, since high-temperature steam does not enter the target plate installation section during target plate replacement but flows through the bypass pipeline, there is no risk of high-temperature leakage causing burns, thus improving safety.

[0019] The steam target testing system of the relevant technology has significant efficiency problems: after the first target test, when replacing the target plate for the second test, the boiler room must be shut down to stop the steam supply, and steam supply can only be resumed after the target plate is replaced. Due to the excessively long steam supply pipeline, it takes a long time to restore the high-temperature steam to the required flow rate and temperature, which seriously affects the efficiency of steam cleaning.
[0020] In view of this, the present application provides a steam target testing system and method, which does not require stopping the steam supply during the entire target testing process, and can significantly improve the working efficiency of target testing.
[0021] Figure 1 This is a schematic overall diagram of a steam target detection system provided in one or more embodiments of this application. Figure 1 As shown, the steam target detection system includes a main pipeline 10, a target plate mounting section 101, a bypass pipeline 20, and a conversion component. The target plate mounting section 101 is located on the main pipeline 10, that is, the target plate mounting section 101 is a segment of the main pipeline 10. The main pipeline 10 includes the target plate mounting section 101 and other pipe segments.
[0022] The main pipeline 10 can transport steam for target practice. The steam inlet of the main pipeline 10 can be connected to a steam equipment 30, such as a boiler, and the steam outlet of the main pipeline 10 can be connected to a steam exhaust equipment 40, such as a chimney. The high-temperature steam generated by the steam equipment 30 can enter the main pipeline 10 from the steam inlet, flow through the main pipeline 10, and finally be discharged from the steam outlet of the main pipeline 10 into the steam exhaust equipment 40, and then discharged from the steam exhaust equipment 40.
[0023] Since the target plate mounting section 101 is located on the main pipeline 10, steam entering the main pipeline 10 from the steam inlet end will also pass through the target plate mounting section 101. Here, the target plate mounting section 101 on the main pipeline 10 can be an integral structure, with the target plate mounting section 101 simply being a segment of the main pipeline 10, without any actual segmented components. Alternatively, the target plate mounting section 101 can be a separate structure from the main pipeline 10. Both ends of the target plate mounting section 101 can be connected to the main pipeline 10 via connectors, such as flanges.
[0024] See also Figure 1 The target plate mounting section 101 is used to install the target plate assembly 102, which is a device that allows for quick installation and removal of the target plate and is used to check and evaluate the cleanliness of the system during the purging process.
[0025] In some embodiments, the target plate assembly 102 may include a target plate holder and a target plate, with the target plate detachably connected to the target plate holder and the target plate holder fixedly connected to the main pipe 10. The target plate may be a polished metal plate (e.g., an aluminum plate, copper plate, or stainless steel plate), with a width that can be 5-8% of the inner diameter of the main pipe 10 and a length that can cover the entire inner diameter of the pipe. Before each purging, a brand new, clean, and measured target plate is installed on the target plate holder for target testing.
[0026] Target testing typically requires at least two passes, necessitating the removal of used target plates from the target plate holder and replacement with brand new ones. To prevent steam leakage, this process necessitates shutting off the steam equipment (30°C) to stop the steam supply, resuming steam supply only after the target plate replacement is complete. Due to the time required to restore the high-temperature steam to the required flow rate and temperature during the steam supply pipeline process, a significant waiting period exists between two target tests, severely impacting the efficiency of steam cleaning.
[0027] like Figure 1As shown, the steam target detection system of this application also includes a bypass pipe 20, the steam inlet and exhaust ends of which are connected to the two ends of the target plate mounting section 101, respectively. The target plate mounting section 101 effectively divides the main pipeline 10 into a first branch pipe 103 and a second branch pipe 104. The steam inlet end of the first branch pipe 103 is the same as the steam inlet end of the main pipeline 10 and is connected to the steam equipment 30. The exhaust ends of the first branch pipe 103 are connected to both the steam inlet end of the target plate mounting section 101 and the steam inlet end of the bypass pipe 20. The exhaust ends of both the target plate mounting section 101 and the bypass pipe 20 are connected to the steam inlet end of the second branch pipe 104. The exhaust end of the second branch pipe 104 is the same as the exhaust end of the main pipeline 10 and is connected to the exhaust equipment 40.
[0028] The switching component is used to switch the connection between the first branch pipe 103 and the target plate mounting section 101, or between the first branch pipe 103 and the bypass pipe 20. Specifically, a three-way valve can be installed at the exhaust end of the first branch pipe 103. The first end of the three-way valve is connected to the first branch pipe 103, the second end of the three-way valve is connected to the target plate mounting section 101, and the third end of the three-way valve is connected to the bypass pipe 20. When the first end and the second end of the three-way valve are connected, the first branch pipe 103 is connected to the target plate mounting section 101; when the first end and the third end of the three-way valve are connected, the first branch pipe 103 is connected to the bypass pipe 20.
[0029] During target firing tests, the switching component connects the first pipe 103 to the target plate mounting section 101, allowing steam to enter the target plate mounting section 101 instead of the bypass pipe 20, thus enabling normal target firing. Figure 2 The steam flow path shown is such that high-temperature steam flows from the steam equipment to the first branch pipe 103, then to the target plate mounting section 101, to the second branch pipe 104, and finally to the exhaust equipment 40.
[0030] When the target plate needs to be replaced, the first branch pipe 103 is switched to be connected to the bypass pipe 20 via the conversion component, allowing steam to enter the bypass pipe 20 instead of the target plate mounting section 101. Figure 3 The steam flow path shown is such that high-temperature steam flows from the steam equipment to the first branch pipe 103, then to the bypass pipe 20, to the second branch pipe 104, and finally to the exhaust equipment 40.
[0031] This method allows for target plate replacement without shutting down the steam equipment 30 or stopping the steam supply. The entire main pipeline 10 remains filled with high-temperature steam. Therefore, target testing can be performed immediately after target plate replacement without waiting, improving testing efficiency and consequently, the overall efficiency of steam cleaning. Furthermore, since the high-temperature steam does not enter the target plate installation section 101 during replacement but flows through the bypass pipeline, there is no risk of high-temperature leakage causing burns, thus enhancing safety.
[0032] In some implementations, such as Figure 1 As shown, the conversion assembly may include a first shut-off valve 501 and a second shut-off valve 502; the first shut-off valve 501 is disposed in the target plate mounting section 101 and is used to connect or disconnect the target plate mounting section 101 from the first branch pipe 103; the second shut-off valve 502 is disposed in the bypass pipe 20 and is used to connect or disconnect the bypass pipe 20 from the first branch pipe 103.
[0033] Specifically, when conducting a target firing test, the first shut-off valve 501 is opened and the second shut-off valve 502 is closed. The first branch pipe 103 is connected to the target plate mounting section 101, while the first branch pipe 103 is cut off from the bypass pipe 20, so that steam enters the target plate mounting section 101 but does not enter the bypass pipe 20, thus allowing the target firing to be carried out normally.
[0034] When the target plate needs to be replaced, the first shut-off valve 501 is closed and the second shut-off valve 502 is opened. The first branch pipe 103 is cut off from the bypass pipe 20, while the first branch pipe 103 is connected to the bypass pipe 20, so that steam enters the bypass pipe 20 and does not enter the target plate installation section 101.
[0035] In some implementations, such as Figure 1 As shown, the steam target detection system also includes a condensate drain pipe 105, which is connected to the target plate mounting section 101. A condensate drain valve 503 is installed on the condensate drain pipe 105, which is used to cut off or connect the condensate drain pipe 105. The condensate drain pipe 105 can discharge condensate and non-condensable gases (such as air) in the steam system, while preventing steam leakage.
[0036] In some embodiments, the steam target detection system further includes: The controller, which is communicatively connected to the conversion component, is configured to: control the conversion component to switch states when a target firing signal is received, so that the target plate mounting section 101 is connected to the first branch pipe 103; Upon receiving a target plate replacement signal, the control conversion component switches its state to connect the bypass pipe to the first branch pipe 103.
[0037] In some implementations, the controller is also configured to open the steam trap 503 upon receiving a target plate replacement signal. That is, the steam trap 503 is only opened when the target plate is being replaced, which further prevents high-temperature steam leakage.
[0038] In some implementations, such as Figure 1 As shown, the steam target detection system also includes a drive pump 60, which is located at the steam inlet end of the main pipeline 10 and is used to adjust the steam delivery rate. The controller is also configured to: upon receiving a target firing signal, control the drive pump 60 to drive steam to be delivered in the pipeline at a first rate; Upon receiving a signal to replace the target plate, the control pump 60 drives steam to be transported in the pipeline at a second rate, which is less than the first rate. In other words, when replacing the target plate, the steam is controlled to flow at a lower rate in the pipeline, while during target firing and testing, the steam is controlled to flow at a higher rate. This ensures that the pipeline is filled with steam while avoiding energy waste.
[0039] Some embodiments of this application also provide a steam target detection method, applied to the steam target detection system in the above embodiments, such as... Figure 4 As shown, the steam target testing method includes the following steps: In step S101, in response to the target firing signal, the control conversion component is switched to the first state so that the first branch pipe 103 is connected to the target plate mounting section 101.
[0040] In step S102, in response to the target plate replacement signal, the control conversion component is switched to the second state so that the first branch pipe 103 is connected to the bypass pipe 20.
[0041] Specifically, the conversion assembly includes a first shut-off valve 501 and a second shut-off valve 502; the first shut-off valve 501 is disposed in the target plate mounting section 101 and is used to connect or disconnect the target plate mounting section 101 from the first branch pipe 103; the second shut-off valve 502 is disposed in the bypass pipe 20 and is used to connect or disconnect the bypass pipe 20 from the first branch pipe 103. Switching the control conversion component to the first state specifically includes: controlling the first shut-off valve 501 to open and controlling the second shut-off valve 502 to close; Switching the control conversion component to the second state specifically includes: controlling the first shut-off valve 501 to close and controlling the second shut-off valve 502 to open.
[0042] Specifically, when conducting a target firing test, the first shut-off valve 501 is opened and the second shut-off valve 502 is closed. The first branch pipe 103 is connected to the target plate mounting section 101, while the first branch pipe 103 is cut off from the bypass pipe 20, so that steam enters the target plate mounting section 101 but does not enter the bypass pipe 20, thus allowing the target firing to be carried out normally.
[0043] When the target plate needs to be replaced, the first shut-off valve 501 is closed and the second shut-off valve 502 is opened. The first branch pipe 103 is cut off from the bypass pipe 20, while the first branch pipe 103 is connected to the bypass pipe 20, so that steam enters the bypass pipe 20 and does not enter the target plate installation section 101.
[0044] In some embodiments, the steam target detection system also includes a drive pump 60, which is located at the steam inlet end of the first branch pipe 103 and is used to regulate the steam delivery rate. Steam target testing methods also include: Upon receiving the target firing signal, the control pump 60 drives steam to be transported in the pipeline at a first rate; specifically, the steam is driven to flow at the first rate through the first branch pipeline 103, the target plate mounting section 101, and the second branch pipeline 104.
[0045] Upon receiving a target plate replacement signal, the control pump 60 drives steam to be transported within the pipeline at a second rate. Specifically, the steam is driven to flow at a first rate through the first branch pipeline 103, the bypass pipeline to 20, and the second branch pipeline 104; wherein the second rate is less than the first rate. When replacing the target plate, the steam is controlled to flow at a lower rate within the pipeline, while during target firing and testing, the steam is controlled to flow at a higher rate within the pipeline. This ensures that the pipeline is filled with steam while avoiding energy waste.
