Description

Technical Field

[0001] The present invention belongs to the technical field of fluid control process monitoring, and in particular, relates to a fluid control process monitoring method and system. Background Art

[0002] With the widespread application of steam fluid transmission pipelines in industrial production, steam traps, as key components in the pipeline system, play a vital role. The main function of the steam trap is to effectively discharge the condensate in the steam system while avoiding steam leakage, thereby ensuring the efficient operation of the system. However, in actual applications, due to various reasons, steam traps often have abnormal conditions, such as flow rate drop and pressure rise, which pose a great threat to the normal operation of the system. Therefore, how to accurately judge the abnormal conditions of steam traps and their root causes has become an important issue to ensure the stable operation of the system.

[0003] In the prior art, although there are some methods for monitoring the operating status of steam traps, these methods usually have many shortcomings. For example, traditional methods mainly rely on simple flow and pressure detection, and cannot confirm the root cause of the abnormality through specific simulation tests. In addition, when the steam trap has an abnormality, the existing technical means are usually unable to accurately analyze the blocking material, which makes it difficult for monitoring personnel to take effective measures for management and maintenance. Summary of the invention

[0004] The object of the present invention is to provide a fluid control process monitoring method and system, aiming to solve the problems raised in the background technology.

[0007] activating a test pipe in the same fluid pipe environment as the target steam trap and placing the test steam trap of the test pipe in the same preset operation mode as the target steam trap;

[0008] Conduct blockage interventions on test pipes;

[0009] During the process of performing the blockage intervention measures on the test pipeline, the fluid flow condition of the test steam trap is continuously observed, and when it is observed at a certain moment that the similarity between the fluid flow condition of the test steam trap and the specific abnormal fluid flow condition of the target steam trap exceeds a preset threshold, the blockage intervention measures are stopped, and the cause of the specific abnormal fluid flow condition of the target steam trap is determined to be an internal blockage;

[0059] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0060] It is understood that the terms "first", "second", etc. used in this application may be used herein to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish a first element from another element. For example, without departing from the scope of this application, a first xx script may be referred to as a second xx script, and similarly, a second xx script may be referred to as a first xx script.

[0061] Figure 1 A flow chart of a method provided by an embodiment of the present invention is shown.

[0062] Specifically, a fluid control process monitoring method comprises the following steps:

[0063] Step S100, continuously observing the fluid flow conditions of the steam traps of a plurality of working pipelines in the same fluid pipeline environment, and when a steam trap is found to have a specific abnormal fluid flow condition, the steam trap is determined to be a target steam trap.

[0064] Specifically, Figure 2 A flow chart for determining a target steam trap is shown.

[0065] The method of continuously observing the fluid flow conditions of the steam traps of several working pipelines in the same fluid pipeline environment and determining that a steam trap is a target steam trap when a specific abnormal fluid flow condition is found in a steam trap specifically includes the following steps:

[0066] Step S101, acquiring real-time flow data and real-time pressure data of steam traps of a plurality of working pipelines in the same fluid pipeline environment;

[0067] Step S102, generating a flow trend line graph and a pressure trend line graph corresponding to the steam traps of each working pipeline according to the real-time flow data and real-time pressure data of the steam traps of different working pipelines;

[0068] Step S103, continuously observing the flow trend line graphs and pressure trend line graphs corresponding to different steam traps, when it is found that the flow trend line graph corresponding to a certain steam trap shows a downward flow trend, and the pressure trend line graph shows an upward pressure trend, it is determined that the steam trap has a specific abnormal fluid flow condition, and the steam trap is set as the target steam trap.

[0069] In an embodiment of the present invention, the fluid pipeline environment used in the present application includes multiple working pipelines for conveying steam fluid, and each working pipeline is equipped with a steam trap for draining water, and a pressure sensor and a flow sensor are installed at the rear end of the steam trap of the working pipeline. The pressure sensor can obtain the pressure of the steam fluid passing through the steam trap in real time, and the flow sensor can obtain the flow of the steam fluid passing through the steam trap in real time.

[0070] When it is found that the flow trend line graph corresponding to a certain steam trap shows a downward flow trend, and the pressure trend line graph shows an upward pressure trend, it is determined that the steam trap has a specific abnormal fluid flow situation. It can be understood that the downward flow trend and the upward pressure trend here should both have a certain time length.

[0071] Furthermore, the fluid control process monitoring method further comprises the following steps:

[0072] Step S200, activating a test pipeline in the same fluid pipeline environment as the target steam trap, and placing the test steam trap of the test pipeline in the same preset operation mode as the target steam trap.

[0073] In the embodiment of the present invention, a test pipeline is also separately provided in the fluid pipeline environment, and the caliber area of ​​the test pipeline is the same as the caliber area of ​​the working pipeline (even if the shape is different), and electromagnetic valves should be installed at both ends of the test pipeline. When the test pipeline needs to be activated, the electromagnetic valves at the both ends of the test pipeline should be opened at the same time, so that the same steam fluid as that in the working pipeline flows into the test pipeline;

[0074] The preset operation mode includes the valve opening and closing angle of the steam trap, the drainage frequency, etc.

[0075] Furthermore, the fluid control process monitoring method further comprises the following steps:

[0076] Step S300, performing blockage intervention measures on the test pipeline;

[0077] performing blockage intervention measures on the test pipeline by means of a blockage intervention structure;

[0078] The blockage intervention structure comprises: a moving element, a simulated blockage, an adsorption element and a sealing element, wherein the moving element and the sealing element are both arranged on the outer surface of the test pipe, the simulated blockage is arranged inside the sealing element, the adsorption element is arranged on the moving element, the moving element is used to drive the adsorption element to move, and the adsorption element is used to adsorb and drive the simulated blockage to move;

[0079] When taking blockage intervention measures, the simulated blockage adsorbed by the adsorption element is driven by the moving element to move inside the sealing element, so that the simulated blockage gradually enters the test pipe to simulate the effect of blockage inside the test pipe.

[0080] Step S400, during the process of performing blockage intervention measures on the test pipeline, the fluid flow condition of the test trap is continuously observed. When at a certain moment, it is observed that the similarity between the fluid flow condition of the test trap and the specific abnormal fluid flow condition of the target trap exceeds a preset threshold, the blockage intervention measures are stopped, and the cause of the specific abnormal fluid flow condition of the target trap is determined to be internal blockage.

[0081] Specifically, Figure 3 A flow chart showing continuous observation of fluid flow through a test steam trap during blockage intervention in a test pipeline.

[0082] In the process of performing the blockage intervention measures on the test pipeline, the fluid flow of the test trap is continuously observed. When the similarity between the fluid flow of the test trap and the specific abnormal fluid flow of the target trap is observed to exceed a preset threshold at a certain moment, the blockage intervention measures are stopped, and it is determined that the cause of the specific abnormal fluid flow of the target trap is internal blockage. Specifically, the following steps are included:

[0083] Step S401, in the process of taking blockage intervention measures on the test pipeline, whenever the simulated blockage is moved to a preset test position, real-time flow data and real-time pressure data of the test steam trap in this state within a preset period of time are obtained, and a flow trend line graph and a pressure trend line graph corresponding to the test steam trap are generated;

[0084] Step S402, comparing the flow trend line graph and pressure trend line graph obtained when the simulated obstruction is at different preset test positions with the flow trend line graph and pressure trend line graph when the target steam trap is in a specific abnormal fluid flow condition for similarity;

[0085] Step S403, when the similarity between the flow trend line graph and the pressure trend line graph obtained when the simulated blockage is in a specific preset test position and the flow trend line graph and the pressure trend line graph when the target steam trap is in a specific abnormal fluid flow condition exceeds a preset threshold, the specific preset test position is determined as the control test position, and the blockage intervention measures are stopped, and it is determined that the cause of the specific abnormal fluid flow condition in the target steam trap is internal blockage.

[0086] In an embodiment of the present invention, the moving element may be an electric telescopic rod, the simulated blockage may be a square panel made of iron (whose outer surface is coated with an anti-corrosion layer), and the test pipe should also be square, and the width of the simulated blockage is the same as the width inside the test pipe, that is, after the simulated blockage enters the test pipe, its two sides are tightly attached to the inner wall of the test pipe, the adsorption element is an electromagnet block, and the sealing element is a connecting cover.

[0087] When the moving element drives the adsorption element box to move the simulated blockage, the movement stroke of the moving element should be obtained in real time, and the movement stroke is the distance that the simulated blockage enters the test pipe.

[0088] The preset thresholds can be pre-set by the monitoring staff, and a machine learning algorithm (such as a neural network or cluster analysis) can be used to compare the flow trend line graph and pressure trend line graph obtained when the simulated blockage is in different preset test positions with the flow trend line graph and pressure trend line graph of the target steam trap when it is in a specific abnormal fluid flow condition.

[0089] It can be understood that when the similarity between the flow trend line graph and the pressure trend line graph obtained when the simulated obstruction is at a specific preset test position and the flow trend line graph and the pressure trend line graph when the target steam trap is in a specific abnormal fluid flow condition exceeds a preset threshold, it means that when the test steam trap is blocked in the piping system (there is a simulated obstruction at the control test position in the test pipeline), the steam fluid flow inside the test steam trap will have fluid flow characteristics similar to the blockage phenomenon inside the target steam trap, and it can be inferred that the cause of the specific abnormal fluid flow condition in the target steam trap is internal blockage.

[0090] Furthermore, the fluid control process monitoring method further comprises the following steps:

[0091] Step S500, obtaining the specific intervention situation of the blockage intervention measure performed on the test pipeline when the similarity between the fluid flow situation of the test steam trap and the specific abnormal fluid flow situation of the target steam trap exceeds a preset threshold, and analyzing the specific blockage cause of the target steam trap according to the specific intervention situation.

[0092] Specifically, Figure 4 A flow chart for determining a specific cause of blockage of a target steam trap is shown.

[0093] The process of obtaining the specific intervention situation of the blockage intervention measures performed on the test pipeline when the similarity between the fluid flow situation of the test steam trap and the specific abnormal fluid flow situation of the target steam trap exceeds a preset threshold value, and analyzing the specific blockage cause of the target steam trap according to the specific intervention situation specifically includes the following steps:

[0094] Step S501, when it is determined that the similarity between the observed fluid flow condition of the test steam trap and the specific abnormal fluid flow condition of the target steam trap exceeds a preset threshold, obtaining a control test position where the simulated blockage is located;

[0095] Step S502, calculating the area ratio of the simulated obstruction inside the test pipe according to the control test position, that is, determining the actual area ratio of the obstruction inside the target steam trap;

[0096] Step S503: retrieve a preset blocking reason comparison table, and search the preset blocking reason comparison table for a specific blocking reason corresponding to the actual occupied area ratio.

[0097] In the embodiment of the present invention, the preset blocking reason comparison table is provided with multiple groups of actual occupied area ratio ranges, and each actual occupied area ratio range corresponds to a specific specific blocking reason. The specific blocking reasons estimated by the occupied area ratio are mainly divided into three categories:

[0098] Minor blockage: This may be caused by some light sediment or particulate matter.

[0099] Medium blockage: This may be caused by a large accumulation of sediment or particulate matter, or by a failure of a smaller component inside the target steam trap (the specific component is pre-determined by the staff).

[0100] Large-area blockage: This may be caused by a malfunction of a larger component inside the target steam trap (the specific component is pre-set by the staff).

[0101] See also Fig. 9 After determining that the cause of the specific abnormal fluid flow in the target steam trap is internal blockage, in order to facilitate the monitoring staff to know the possible blockages inside the target steam trap and facilitate the maintenance personnel to prepare, the background processing cloud obtains the height inside the test pipe and the movement stroke of the moving element (that is, the distance of the simulated blockage entering the test pipe), and then calculates the ratio between the running stroke and the height inside the test pipe, so as to obtain the area ratio of the simulated blockage inside the test pipe, that is, determine the actual area ratio of the blockage inside the target steam trap, and finally take the preset blockage cause comparison table, and find the specific blockage cause corresponding to the actual area ratio in the preset blockage cause comparison table.

[0102] Through the above technical solution, when the steam trap has abnormal conditions of flow rate drop and pressure rise at the same time, it can be determined whether the root cause of these abnormal phenomena is due to internal blockage through accurate simulated environmental tests. Once it is confirmed that the abnormality is caused by internal blockage, the specific blocking material can be accurately analyzed to help monitoring personnel accurately identify the specific cause of the abnormality of the steam trap, thereby effectively managing and allocating maintenance resources.

[0104] Among them, in another preferred embodiment provided by the present invention, a fluid control process monitoring system includes:

[0105] The target steam trap determination module 100 is used to continuously observe the fluid flow conditions of steam traps of a plurality of working pipelines in the same fluid pipeline environment, and when a steam trap is found to have a specific abnormal fluid flow condition, the steam trap is determined to be a target steam trap.

[0122] The test trap continuous observation module 400 is used to continuously observe the fluid flow condition of the test trap during the process of performing blockage intervention measures on the test pipeline. When the similarity between the fluid flow condition of the test trap and the specific abnormal fluid flow condition of the target trap observed at a certain moment exceeds a preset threshold, the blockage intervention measures are stopped, and the cause of the specific abnormal fluid flow condition of the target trap is determined to be internal blockage.

[0123] Specifically, Figure 7 The structure block diagram of the continuous observation module 400 for testing the steam trap in the system provided by the embodiment of the present invention is shown.

[0124] Among them, in the preferred embodiment provided by the present invention, the test steam trap continuous observation module 400 specifically includes:

[0125] The second line graph generating unit 401 is used for obtaining the real-time flow data and real-time pressure data of the test steam trap in the state within a preset period of time and generating a flow trend line graph and a pressure trend line graph corresponding to the test steam trap whenever the simulated blockage is moved to a preset test position during the process of performing blockage intervention measures on the test pipeline;

[0126] A line graph comparison unit 402 is used to compare the flow trend line graph and pressure trend line graph obtained when the simulated blockage is at different preset test positions with the flow trend line graph and pressure trend line graph when the target steam trap is in a specific abnormal fluid flow condition.

[0127] The internal blockage cause determination unit 403 is used to determine that the specific preset test position is a control test position, stop the blockage intervention measures, and determine that the cause of the specific abnormal fluid flow condition in the target steam trap is internal blockage when the similarity between the flow trend line graph and the pressure trend line graph obtained when the simulated blockage is in the specific preset test position and the flow trend line graph and the pressure trend line graph when the target steam trap is in a specific abnormal fluid flow condition exceeds a preset threshold.

[0128] In an embodiment of the present invention, the moving element may be an electric telescopic rod, the simulated blockage may be a square panel made of iron (whose outer surface is coated with an anti-corrosion layer), and the test pipe should also be square, and the width of the simulated blockage is the same as the width inside the test pipe, that is, after the simulated blockage enters the test pipe, its two sides are tightly attached to the inner wall of the test pipe, the adsorption element is an electromagnet block, and the sealing element is a connecting cover.

[0129] When the moving element drives the adsorption element box to move the simulated blockage, the movement stroke of the moving element should be obtained in real time, and the movement stroke is the distance that the simulated blockage enters the test pipe.

[0130] The preset thresholds can be pre-set by the monitoring staff, and a machine learning algorithm (such as a neural network or cluster analysis) can be used to compare the flow trend line graph and pressure trend line graph obtained when the simulated blockage is in different preset test positions with the flow trend line graph and pressure trend line graph of the target steam trap when it is in a specific abnormal fluid flow condition.

[0131] It can be understood that when the similarity between the flow trend line graph and the pressure trend line graph obtained when the simulated obstruction is at a specific preset test position and the flow trend line graph and the pressure trend line graph when the target steam trap is in a specific abnormal fluid flow condition exceeds a preset threshold, it means that when the test steam trap is blocked in the piping system (there is a simulated obstruction at the control test position in the test pipeline), the steam fluid flow inside the test steam trap will have fluid flow characteristics similar to the blockage phenomenon inside the target steam trap, and it can be inferred that the cause of the specific abnormal fluid flow condition in the target steam trap is internal blockage.

[0132] Furthermore, the fluid control process monitoring system also includes:

[0133] The specific blockage cause determination module 500 is used to obtain the specific intervention situation of the blockage intervention measures performed on the test pipeline when the similarity between the fluid flow situation of the test steam trap and the specific abnormal fluid flow situation of the target steam trap exceeds a preset threshold, and analyze the specific blockage cause of the target steam trap according to the specific intervention situation.

[0134] Specifically, Figure 8 It shows a structural block diagram of a specific blockage cause determination module 500 in the system provided by an embodiment of the present invention.

[0135] Among them, in the preferred embodiment provided by the present invention, the specific blocking cause determination module 500 specifically includes:

[0136] A control test position determination unit 501 is used to obtain a control test position where a simulated obstruction is located when it is determined that the similarity between the observed fluid flow condition of the test trap and the specific abnormal fluid flow condition of the target trap exceeds a preset threshold;

[0137] The actual occupied area ratio calculation unit 502 is used to calculate the area ratio of the simulated obstruction inside the test pipe according to the control test position, that is, to determine the actual occupied area ratio of the obstruction inside the target steam trap;

[0138] A specific congestion cause query unit 503 is used to retrieve a preset congestion cause comparison table and search for a specific congestion cause corresponding to the actual occupied area ratio in the preset congestion cause comparison table;

[0139] The preset blocking reason comparison table is provided with a plurality of groups of actual occupied area ratio ranges, and each actual occupied area ratio range corresponds to a specific blocking reason.

[0140] In the embodiment of the present invention, the preset blocking reason comparison table is provided with multiple groups of actual occupied area ratio ranges, and each actual occupied area ratio range corresponds to a specific specific blocking reason. The specific blocking reasons estimated by the occupied area ratio are mainly divided into three categories:

[0141] Minor blockage: This may be caused by some light sediment or particulate matter.

[0142] Medium blockage: This may be caused by a large accumulation of sediment or particulate matter, or by a failure of a smaller component inside the target steam trap (the specific component is pre-determined by the staff).

[0143] Large-area blockage: This may be caused by a malfunction of a larger component inside the target steam trap (the specific component is pre-set by the staff).

[0144] See also Fig. 9After determining that the cause of the specific abnormal fluid flow in the target steam trap is internal blockage, in order to facilitate the monitoring staff to know the possible blockages inside the target steam trap and facilitate the maintenance personnel to prepare, the background processing cloud obtains the height inside the test pipe and the movement stroke of the moving element (that is, the distance of the simulated blockage entering the test pipe), and then calculates the ratio between the running stroke and the height inside the test pipe, so as to obtain the area ratio of the simulated blockage inside the test pipe, that is, determine the actual area ratio of the blockage inside the target steam trap, and finally take the preset blockage cause comparison table, and find the specific blockage cause corresponding to the actual area ratio in the preset blockage cause comparison table.

[0145] Through the above technical solution, when the steam trap has abnormal conditions of flow rate drop and pressure rise at the same time, it can be determined whether the root cause of these abnormal phenomena is due to internal blockage through accurate simulated environmental tests. Once it is confirmed that the abnormality is caused by internal blockage, the specific blocking material can be accurately analyzed to help monitoring personnel accurately identify the specific cause of the abnormality of the steam trap, thereby effectively managing and allocating maintenance resources.
