Description

Technical Field

[0001] This application belongs to the field of solution monitoring technology, and relates to a leakage monitoring device and a leakage collection system. Background Technology

[0002] Under current technological conditions, solution leakage, especially from strong acid or alkali solutions, can cause serious damage to the surrounding natural environment. Taking sodium hypochlorite stock solution as an example, it not only has strong reducing properties but also forms a strongly alkaline solution after dissolving in water, posing a significant threat to surrounding agriculture, forestry, and fisheries. Although the stress on the pipeline network and the risks of pipe bursts and ruptures have been effectively controlled through flexible connection modifications to pipe joints, the risk of leakage at flange surfaces still exists. Therefore, how to quickly and accurately monitor solution leakage has become an urgent technical problem to be solved. Utility Model Content

[0003] This application provides a leakage monitoring device and a leakage collection system for collecting leakage liquid seeping from the monitored flange surface and for monitoring leakage liquid by measuring changes in the pH value of the liquid in the reservoir.

[0004] In a first aspect, embodiments of this application provide a leakage monitoring device, comprising: a flange leakage sleeve; and a reservoir for receiving leakage fluid collected by the flange leakage sleeve, so as to monitor the leakage of the leakage fluid within the reservoir.

[0005] In one implementation of the first aspect, the flange face being monitored is embedded in the flange face leakage sleeve.

[0006] In one implementation of the first aspect, the device further includes a leakage delivery pipe, the two ends of which are connected to the flange leakage sleeve and the reservoir, respectively, for directing the leakage to be tested into the reservoir.

[0007] In one implementation of the first aspect, the reservoir stores a pre-prepared liquid.

[0008] In one implementation of the first aspect, the pre-prepared liquid includes at least one of potassium chloride solution and distilled water.

[0009] In one implementation of the first aspect, the reservoir is further equipped with a pH electrode, which is used to detect the pH value after the pre-prepared liquid reacts with the test liquid.

[0010] In one implementation of the first aspect, the device further includes a signal transmitter connected to the pH electrode, for issuing an alarm signal based on an abnormal pH value detected by the pH electrode.

[0011] In one implementation of the first aspect, the device further includes a communication module connected to the signal transmitter for making a telephone alarm based on the received alarm signal.

[0012] The leakage monitoring device provided in this application includes: a flange leakage sleeve; and a reservoir for receiving the leakage liquid to be tested collected by the flange leakage sleeve, so as to monitor the leakage of the leakage liquid to be tested within the reservoir. Based on the principle that the pH value of the pre-prepared liquid changes rapidly after it reacts with the leakage liquid to be tested after being mixed in the reservoir, the leakage of the leakage liquid to be tested is accurately monitored by a pH electrode in the reservoir, so that relevant technicians can repair and handle the leakage device in a timely manner, and avoid damage to the surrounding natural environment caused by solution leakage.

[0013] Secondly, embodiments of this application provide a leakage collection system, including a leakage collection tank and a leakage monitoring device as described in any of the first aspects, wherein the leakage monitoring device includes a reservoir; the reservoir is disposed inside the leakage collection tank.

[0014] In one implementation of the second aspect, the reservoir is provided with an overflow pipe at a preset height. When the height of the liquid after the reaction between the preset liquid and the leaking liquid to be tested in the reservoir is greater than the preset height, the overflow pipe is used to allow the liquid in the reservoir to flow into the leaking liquid collection tank.

Therefore, the drawings only show the components related to this application and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the shape, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0029] Existing monitoring devices lack rapid and accurate monitoring capabilities for detecting microleakage of solutions.

[0030] To address at least the aforementioned problems, this application provides a leakage monitoring device. The leakage monitoring device includes: a flange leakage sleeve; and a reservoir for receiving the leakage fluid collected by the flange leakage sleeve, so as to monitor the leakage of the leakage fluid within the reservoir. This solves the technical problem of the lack of a rapid and accurate method for monitoring solution leakage in the prior art.

[0031] The technical solutions in the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0032] Figure 1 The image shown is a cross-sectional view of a leakage monitoring device provided in an embodiment of this application. Figure 1 As shown, the leakage monitoring device 100 includes a flange leakage sleeve 110 and a reservoir 120 for receiving the leakage liquid to be tested collected by the flange leakage sleeve 110 and monitoring the pH value of the leakage liquid to be tested.

[0033] The device also includes a monitored flange face 130, which is embedded in the flange face leakage sleeve 110.

[0034] For example, the flange face leakage sleeve 110 and the monitored flange face 130 are located on the same center line.

[0035] It should be noted that the fact that the flange leakage sleeve 110 and the monitored flange face 130 are located on the same center line is only for illustrative purposes. In actual applications, the monitored flange face 130 can be set at any suitable position inside the flange leakage sleeve 110, which will not be elaborated further in this application.

[0036] The device further includes a leakage delivery pipe 140, the two ends of which are connected to the flange leakage sleeve 110 and the reservoir 120, respectively, for delivering the leakage liquid to be tested into the reservoir 120.

[0037] In some embodiments, the reservoir 120 is further equipped with a pH electrode 150, which is used to detect the pH value after the pre-prepared liquid reacts with the test liquid.

[0038] In some embodiments, the device further includes a signal transmitter connected to the pH electrode 150 for issuing an alarm signal based on an abnormal pH value detected by the pH electrode 150.

[0039] In some embodiments, the reservoir 120 stores a pre-prepared liquid.

[0040] For example, the pre-prepared liquid includes at least one of potassium chloride solution and distilled water.

[0041] It should be noted that the types of pre-prepared liquids listed above are merely illustrative examples. In practical applications, any other suitable type of pre-prepared liquid can be selected according to the specific scenario, and this application does not impose any restrictions on this.

[0042] Please see Figure 2 , Figure 2 The diagram shown illustrates another leakage monitoring device provided in one embodiment of this application. Figure 2 As shown, the reservoir 120 is equipped with an overflow pipe 160 at a preset height.

[0043] The preset height is less than the actual height of the liquid reservoir 120.

[0044] For example, if the actual height of the reservoir 120 is 50cm, the preset height can be set to 30cm, 40cm, 20cm, etc.

[0045] It should be noted that the actual height of the reservoir 120 and the preset height of the overflow pipe 160 listed above are merely illustrative examples of this application. In actual applications, any other suitable preset height can be determined according to specific application requirements, and this application does not impose any restrictions on this.

[0046] For example, the overflow pipe 160 may be located on the left side of the reservoir 120.

[0047] It should be noted that the specific position of the overflow pipe 160 relative to the reservoir 120 in this embodiment is only for illustrative purposes. In actual applications, the overflow pipe 160 can be placed on either side of the reservoir 120 according to specific application requirements. This application does not limit the specific position of the overflow pipe 160 in the reservoir 120.

[0048] Specifically, if the test solution leaks from the monitored flange face 130, the flange face leakage sleeve 110 collects the leaked test solution and transfers it to the reservoir 120 via the leakage delivery pipe 140. There, the test solution mixes with the pre-placed liquid in the reservoir 120, undergoing a fusion reaction. Based on the principle that the pH value of the pre-placed liquid changes rapidly after the fusion reaction, detecting this pH change indicates a micro-leakage of the test solution from the monitored flange face 130. For example, if the test solution is sodium hypochlorite stock solution and the pre-prepared liquid is distilled water, the reaction that occurs after the sodium hypochlorite stock solution and distilled water are mixed is: NaClO + H2O → NaOH + HClO, which increases the pH value of the pre-prepared liquid. The pH electrode 150 promptly detects the abnormal pH value of the pre-prepared liquid and sends the abnormal pH value to the signal transmitter so that the signal transmitter can issue an alarm signal. After receiving the alarm signal sent by the signal transmitter, the communication module promptly sends the alarm signal to the relevant person in charge via telephone alarm to remind the person in charge to deal with the abnormal situation in a timely manner.

[0049] The leakage monitoring device provided in this application embodiment can monitor micro-leakage on the flange surface in real time. By detecting changes in the pH value of the standard solution, it can quickly detect signs of leakage, and is more sensitive to minor leaks, enabling it to issue alarms earlier. This gives relevant technicians more time to take countermeasures and prevent the leakage from escalating. The entire monitoring process is in a fully enclosed state, with no leakage causing secondary pollution to the surrounding environment, thus protecting the ecological environment and the safety of surrounding organisms to the greatest extent. This device has broad application prospects in chemical, environmental protection and other fields, providing related industries with a safer, more reliable and environmentally friendly leakage monitoring solution.

[0050] Please see Figure 3 , Figure 3 The diagram shown illustrates another leakage monitoring device provided in one embodiment of this application. Figure 3 As shown, the overflow pipe 160 can be located on the right side of the reservoir 120.

[0051] Figure 3 Leakage monitoring device and Figure 2 The leakage monitoring device is similar in structure except for the location of the overflow pipe 160, and will not be described in detail here.

[0052] Please see Figure 4 , Figure 4 The diagram shown is a longitudinal cross-sectional view of a flange leakage sleeve provided in an embodiment of this application. Figure 4 The longitudinal cross-sectional diagram of the flange leakage sleeve 110 in the diagram is shown for ease of understanding. Figure 4 The structure of the flange face leakage sleeve 110 is the same as described above. Figures 1 to 3The structure of the flange face leakage sleeve 110 is similar, and will not be described in detail here.

[0053] Please see Figure 5 , Figure 5 The diagram shown is a schematic representation of a leakage collection system provided in an embodiment of this application. Figure 5 As shown, the leakage collection system 200 includes: a leakage collection tank 210; and a leakage monitoring device 100, wherein the leakage monitoring device includes a reservoir 120; the reservoir 120 is disposed inside the leakage collection tank 210.

[0054] The flange leakage sleeve 110 is inclined relative to the leakage collection box 210 and is located above the leakage collection box 210.

[0055] In some embodiments, an overflow pipe 160 is provided at a preset height of the liquid reservoir 120. When the liquid level after the reaction between the pre-set liquid and the leaking liquid to be tested in the liquid reservoir 120 exceeds the preset height, the overflow pipe 160 is used to divert the liquid in the liquid reservoir 120 into the leak collection tank 210. The leak collection tank 210 can promptly collect the liquid flowing out of the liquid reservoir 120, increasing the time for on-site personnel to arrive and handle the situation, and enhancing the resilience of the pipeline network's safe operation during holidays.

[0056] For example, the leakage collection box 210 in this embodiment of the application is in the shape of a cube or a cuboid.

[0057] It should be noted that the shape of the leakage collection box 210 can also be a cylinder, an elliptical cylinder, etc. In practical applications, any suitable shape of leakage collection box 210 can be selected according to specific application requirements, and this application does not impose any restrictions on this.

[0058] The leak collection system 200 of this application features micro-leakage monitoring, alarm, and leak collection functions. It enables real-time monitoring, rapid response, multi-functional integration, effective leak collection, reduced safety risks, and ensures good economic efficiency, providing safer, more reliable, and environmentally friendly protection for the storage and transportation of solutions, especially strong acid or strong alkali solutions. The integrated design of the leak collection system makes the system structure more compact, easier to install and use, and significantly reduces maintenance and labor costs. The centralized collection of leaks under test through the leak collection tank in the system avoids environmental pollution caused by indiscriminate discharge.

[0059] Please see Figure 6 , Figure 6 The diagram shown is a schematic representation of a leakage collection system provided in an embodiment of this application. Figure 6 As shown, the flange face leakage sleeve 110 is horizontally positioned above the leakage collection box 210.

[0060] It should be noted that the above-mentioned flange leakage sleeve 110 can be horizontally installed above the leakage collection box 210. The flange leakage sleeve 110 can also form a certain angle with the leakage collection box 210 and be installed above the leakage collection box 210. In actual applications, any suitable installation method can be selected for the flange leakage sleeve 110 according to specific application requirements. This application does not impose any restrictions on this.
