With the rapid development of the industrial and energy fields, the adsorber is used as an important device and is widely applied to occasions such as gas separation, storage, purification and the like. The use of adsorbers, especially in hydrogen-rich environments, is becoming increasingly common. However, the hydrogen-rich environment has increasingly significant impact on fatigue damage to the adsorber material, and the specificity of this environment makes the adsorber susceptible to performance degradation during long-term operation, even leading to equipment failure, making the reliability and safety of the adsorber a significant challenge.

However, these single detection methods often fail to fully and accurately evaluate the actual damage condition of the adsorber under complex working conditions. Particularly, under the combined action of a hydrogen-rich environment and alternating load, a single detection means is difficult to comprehensively reflect the evolution process of the damage. Therefore, comprehensive evaluation is urgently needed by adopting a mode of combining multiple detection technologies, and different damage modes of the absorber are monitored in real time, so that the accuracy and the sensitivity of damage detection are improved.

In the following, the technical solutions of the present application will be clearly and completely described with reference to the accompanying drawings, and it should be understood that the described embodiments are only some embodiments of the present application, but not all embodiments of the present application, and that the present application is not limited by the exemplary embodiments described herein. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application. It should be further noted that, for convenience of description, only some, but not all of the drawings related to the present application are shown.
Referring to fig. 1, the application provides a damage evaluation method for a pressure swing adsorption device, which is applied to the damage evaluation device of the pressure swing adsorption device, and specifically includes the following steps:
The method comprises the steps of collecting operation data of the pressure swing adsorption device in real time through a sensor system, inputting the operation data into a damage evaluation model to perform state monitoring on the pressure swing adsorption device, and obtaining a state monitoring result.
Specifically, the sensor system is used for collecting the operation data of the pressure swing adsorption device in real time, firstly, the sensor can monitor and record the working parameters of each key component in the device, such as pressure, temperature, flow, gas concentration and the like, and the data can reflect the actual operation condition of the device. For example, when the gas flow rate of an adsorbent bed is reduced, it may mean that its adsorption capacity is reduced or that there is a plugging problem. Then, the operation data collected in real time are input into a damage evaluation model, and the damage evaluation model can identify whether the equipment has damage or fault signs by analyzing the input data. For example, when abnormal fluctuations in temperature and pressure of the adsorbent bed occur, the model may determine that it is agglomerated or damaged. Finally, the state monitoring is carried out through the output result of the damage evaluation model, and the system can evaluate the health state of the equipment and generate a monitoring result. For example, when the health status score of the device is below a set threshold, the system may issue an early warning, alerting the operator to make a repair or adjustment.
And secondly, carrying out damage mode identification according to the monitoring result in the state monitoring results to obtain damage mode data.
Specifically, according to the monitoring result of the state monitoring results, first, the state monitoring results include various operation data of the pressure swing adsorption device, such as real-time values of temperature, pressure, flow rate, and the like. These data reflect the operating state of the device. Then, by performing damage pattern recognition on these monitoring results, the system can analyze different damage patterns. For example, if the device is operated at high temperature, pressure fluctuations occur, which may be an indication of damage to the seal ring. By analyzing the trend of the data changes in the monitoring results, the system can identify the potential damage cause behind those changes. Damage pattern data refers to data information derived during analysis that indicates the type of equipment damage, such as possible seal ring damage, adsorbent bed plugging, or other internal failures. Through the damage mode data, maintenance personnel can be further guided to take corresponding repair measures, and normal operation of equipment is ensured.
And thirdly, carrying out health state evaluation based on the damage mode data to obtain a health evaluation result.
Specifically, the health state evaluation is performed based on the damage mode data, and the damage mode data is firstly required to be known to be obtained through monitoring and analyzing the running state of the equipment, so that the specific damage condition of the equipment can be revealed. By entering these damage pattern data into the health assessment model, the system will assess its current health status in combination with the normal operating criteria of the device. For example, if the sensors of the device detect excessive temperatures or low pressures, the damage pattern data may be used to determine if the device is excessively worn or damaged. The result of the health status assessment is based on these analysis data to draw conclusions as to whether the device needs maintenance or can continue to operate safely.
And fourthly, continuously monitoring the pressure swing adsorption device according to the health evaluation result.
Specifically, the continuous monitoring of the pressure swing adsorption device according to the health evaluation result means that after the preliminary health state evaluation is completed, the system determines whether the pressure swing adsorption device needs to be monitored for a long time and continuously according to the evaluation result. For example, if the evaluation result shows that the device health is high, the monitoring frequency may be selected to be reduced, and only during critical periods of time. However, if the evaluation result shows that the health degree is low, the monitoring frequency needs to be increased, and various operation parameters of the device, such as temperature, pressure, flow rate and the like, may be tracked in real time. The purpose of the continuous monitoring is to identify potential problems ahead of time before the device fails, thereby avoiding abrupt shut down or significant damage to the device. Through the continuous monitoring, the equipment can be ensured to be kept stable in the long-time operation process, possible faults can be found in time, corresponding maintenance measures can be taken, and the service life of the equipment is prolonged.
The damage evaluation method of the pressure swing adsorption device is applied to the damage evaluation device of the pressure swing adsorption device, can realize the technical aim of multi-mode quantitative detection, achieves the technical effects of comprehensively and accurately monitoring the damage of the adsorber, and improves the reliability of damage identification, thereby effectively prolonging the service life of equipment and ensuring the safe operation of the equipment.
The method comprises the steps of acquiring real-time data, acquiring a real-time state of an initial sensor system, acquiring a real-time state, acquiring a self-adaptive calibration mapping relation, acquiring a sensor repair strategy, and repairing the initial sensor system according to the sensor repair strategy, wherein the self-adaptive calibration mapping relation comprises a mapping relation between the device data and the device state, the initial sensor system is subjected to device health identification based on the real-time state, and the sensor system is acquired.
Specifically, the adaptive calibration mapping is a dynamic adjustment mechanism that calibrates the device according to real-time data, ensuring that errors between the device's measurement results and the actual state are minimized. By collecting real-time data, the system can reflect the current working state of the equipment, such as temperature, pressure or vibration information. Then, by means of the device status recognition technique, the system deduces from these data the actual operating conditions of the device, such as whether the device is normal or whether there is a sign of failure. The real-time state refers to the health and performance status of the device at the current time, for example, if the temperature of the device exceeds a set range, the system may determine it as an abnormal state. The self-adaptive calibration mapping is to provide a mechanism capable of adjusting and optimizing equipment monitoring in real time by mapping the relation between the operation data and the state of the equipment, so as to ensure the accuracy of equipment state monitoring.
After obtaining the real-time status, the system performs health assessment based on the current status of the device, e.g., analyzing whether the temperature, pressure of the device is within normal operating range. If the health of the device shows a potential risk of failure, the system initiates a device health identification procedure to evaluate whether the device needs repair. Sensor repair strategies are a system-proposed solution aimed at improving or restoring the function of the sensor. For example, if the sensor drifts, resulting in inaccurate data, the system may recommend recalibration or replacement of the sensor. Implementation of this strategy helps to ensure accuracy and reliability of the device, avoiding affecting the overall performance of the device due to sensor failure.
After the sensor repair strategy is formulated, the actual repair work is performed next. For example, the sensors of the device may be cleaned, recalibrated, or replaced for damaged sensor components in accordance with a repair strategy. By these repair measures, the system is able to restore the function of the sensor so that it can re-provide accurate data output. And finally, restoring the normal operation of the repaired sensor system, and ensuring that the equipment can continuously monitor and control various working parameters so as to realize long-term stable operation of the equipment.
The method comprises the steps of collecting historical operation data and fault records, constructing a damage assessment model, extracting pressure fluctuation according to the operation data, inputting the pressure fluctuation to the pressure analysis channel, carrying out pressure fluctuation analysis, obtaining a pressure monitoring result, extracting temperature fluctuation according to the operation data, inputting the temperature fluctuation to the temperature analysis channel, carrying out temperature fluctuation analysis, obtaining a temperature monitoring result, extracting gas flow according to the operation data, inputting the gas flow to the flow analysis channel, carrying out gas flow analysis, obtaining a flow monitoring result, extracting gas concentration according to the operation data, inputting the gas concentration to the concentration analysis channel, carrying out gas concentration analysis, obtaining a concentration monitoring result, and combining the pressure monitoring result, the temperature monitoring result, the flow monitoring result and the concentration monitoring result to obtain the state monitoring result.
In particular, the collection of historical operating data refers to data obtained from the long-term operation of a device or system that is capable of reflecting the performance of the device over different time periods. For example, a history of indicators such as pressure, temperature, flow, etc. of the operation of the device, which can help us understand the normal and abnormal conditions of the device. Meanwhile, the fault record refers to relevant information when the equipment fails in the running process, such as fault type, occurrence time, duration time and the like. This information contributes to the potential problems that the analysis device may have. By collecting this data, a lesion assessment model can be constructed that includes various analysis channels, such as pressure, temperature, flow and concentration analysis channels. The channels respectively correspond to the monitoring and analysis of different parameters in the equipment, and each channel has the function of carrying out deep analysis on specific variables so as to evaluate the health state of the equipment.
Next, in the damage evaluation process, information of pressure fluctuation is first extracted from the historical operation data. Pressure fluctuations refer to the change in pressure values over time during operation of the device. If the pressure changes outside the normal range of the design of the device, damage to the device may result. After extracting these fluctuation data, they are input to a pressure analysis channel, which is dedicated to analyzing the law of variation of pressure. By analyzing the pressure fluctuation, the system can identify whether the equipment has abnormal pressure fluctuation, and then a pressure monitoring result is obtained. These results help assess the risk of damage to the equipment due to pressure anomalies.
Temperature fluctuations refer to changes in the temperature of the device during operation, which may lead to damage to the device, for example, if the device fluctuates too much during a certain period of time. The system can identify trends or conditions of temperature anomalies by extracting temperature fluctuation information from historical operating data and inputting the temperature fluctuation information to a temperature analysis channel for detailed analysis. Finally, after temperature fluctuation analysis, the system can obtain a temperature monitoring result, which is helpful for judging whether the equipment is in a normal temperature range, so that safe operation of the equipment is ensured.
The fluctuation of the gas flow refers to the change of the gas flow with time during the operation of the device. If the flow fluctuation exceeds the normal range, this may mean that a problem arises with a certain component of the apparatus. By extracting flow data from the historical operational data and inputting it into the flow analysis channel, the system is able to analyze the flow in detail. The flow analysis can help the monitoring system identify whether a flow abnormality exists, thereby judging whether the device is in a normal operation state. Eventually, the analysis results will provide flow monitoring results that help assess the health of the device.
The change in gas concentration may affect the operating efficiency of the device or reflect problems such as leakage or clogging inside the system. By extracting the gas concentration information in the operation data and inputting the information to the concentration analysis channel, the system will analyze the trend of the concentration change. This process can help identify if the gas concentration is in the normal range, obtain concentration monitoring results, and further help determine if the equipment is at risk of failure.
Finally, the system performs comprehensive analysis on the results obtained from the pressure monitoring, the temperature monitoring, the flow monitoring and the concentration monitoring. By combining the monitoring results of these different parameters, the system is able to comprehensively evaluate the status of the device. If any of the parameters are abnormal, the system will give a warning to indicate that the device may be at risk of potential failure. By combining analysis of a plurality of monitoring results, the overall health condition of the equipment can be reflected more accurately, so that powerful support is provided for maintenance and repair.
The method comprises the steps of detecting valve deformation of a pressure swing adsorption device to obtain a first detection result, evaluating connection stability of a pipeline and a joint of the pressure swing adsorption device to obtain a second detection result, identifying abrasion of an adsorption bed structure of the pressure swing adsorption device to obtain a third detection result, detecting air tightness of the first detection result, the second detection result and the third detection result according to an air tightness judging threshold value, and collecting operation data based on the air tightness result.
In particular, valves in pressure swing adsorption units are important components to control gas flow, and deformation thereof may lead to gas flow restrictions or equipment failure. Valve deformation detection is performed by measuring and analyzing the geometry of the valve to check whether it has deformed due to pressure, temperature changes or other external factors. The detection method can include the steps of using a sensor, a displacement meter and other tools to collect deformation data of the valve in real time, so that the valve can still work normally. The first detection result is the deformation degree of the valve, and the result can reflect whether the valve needs maintenance or replacement.
Secondly, the piping and joint connection of the pressure swing adsorption apparatus is a critical part to ensure smooth gas flow. The stability of the piping and fittings is related to the tightness of the system and the overall operating efficiency. The stability evaluation of the pipe connection includes checking whether the pipe has problems such as cracks, looseness, leakage and the like, while the stability of the joint connection is ensured to ensure that all the connection parts have no leakage, looseness or falling. By means of pressure test, vibration analysis and other methods, whether the pipeline and the joint can bear long-time work load or not can be judged, and safe operation of equipment is ensured. The second test result obtained is then the result of evaluating the stability of the pipe and joint connection, which contributes to the evaluation of the reliability and maintenance requirements of the device.
The adsorbent bed is then the core component of the pressure swing adsorption apparatus, whose primary function is to adsorb impurities from the gas. During long-term use, the adsorbent bed may wear, resulting in reduced adsorption efficiency and even affecting the overall performance of the device. Therefore, the abrasion identification of the adsorption bed structure is to check the surface, pores and the whole structure of the adsorption bed to judge whether the phenomena of crack, breakage, aging and the like exist. The abrasion degree of the adsorption bed can be obtained in real time through methods such as vibration analysis, sound wave detection or temperature monitoring. The third detection result is the evaluation data about the abrasion condition of the adsorbent bed, and can help to judge whether the adsorbent bed needs to be replaced or not so as to restore the adsorption effect of the equipment.
Finally, tightness is an important indicator for evaluating the safety and efficiency of pressure swing adsorption devices. And according to a preset air tightness judging threshold, the system evaluates the air tightness state of the whole equipment by combining the first detection result, the second detection result and the third detection result. If the deformation of the valve, the stability of the pipeline joint and the abrasion degree of the adsorption bed meet the air tightness requirements, the equipment can maintain good sealing performance and avoid gas leakage, and if the detection result shows that the problem exists, the air tightness judgment can warn the equipment that the leakage risk possibly exists. Based on the air tightness judging result, the system further collects data related to the operation of the equipment so as to monitor and early warn in real time and ensure the normal operation of the equipment.
The method comprises the steps of detecting the adsorption bed blockage of the pressure swing adsorption device according to preset pressure fluctuation, detecting the adsorption and desorption functions of the pressure swing adsorption device according to a preset temperature range, detecting the functions, detecting the agglomeration of the adsorbent according to a preset descending trend, detecting the agglomeration of the adsorbent, detecting the adsorbent, and obtaining the damage mode data by combining the adsorption bed monitoring result, the function monitoring result and the adsorbent monitoring result.
Specifically, by the pressure data extracted from the state monitoring result, it is possible to monitor whether or not there is a pressure abnormality fluctuation in the system. Pressure fluctuations may indicate plugging or unsmooth adsorption beds, which often result in limited gas flow and reduced plant efficiency. By comparing the preset pressure fluctuation range, if the monitored pressure fluctuation exceeds the normal range, whether the adsorption bed is blocked or not can be judged. After the adsorption bed blockage is identified, the system can output an adsorption bed monitoring result to provide diagnosis information of whether the equipment is blocked or not.
Second, in pressure swing adsorption units, adsorption and desorption are typically required to be performed under specific temperature conditions, and therefore monitoring of temperature fluctuations is critical. By extracting temperature data from the state monitoring results, it can be judged whether the apparatus is within a preset temperature range. If the temperature exceeds the normal operating range, the adsorption and desorption process may be affected, resulting in malfunction of the apparatus. Therefore, the system analyzes the temperature data and detects the adsorption and desorption functions according to a preset temperature range. According to the detection result, the system can output a function monitoring result to judge whether the equipment works normally.
Then, the flow rate monitoring result can reflect the flowing state of the gas, and the concentration monitoring result can reflect the purifying effect of the gas in the adsorption process. If an abnormal drop in flow or concentration occurs, it may be due to agglomeration of the adsorbent, resulting in a drop in the performance of the adsorption apparatus. Therefore, by analyzing the flow and concentration monitoring data and comparing with a preset trend down, the system can identify whether there is an adsorbent agglomeration phenomenon. The agglomeration of the adsorbent affects the adsorption efficiency of the gas, so that the system can obtain the monitoring result of the adsorbent by identifying the phenomenon, so as to guide the maintenance of equipment.
Finally, the damage pattern data is important information reflecting the overall health status of the pressure swing adsorption apparatus. By combining the adsorption bed monitoring result, the function monitoring result and the adsorbent monitoring result, the operation state of the apparatus can be comprehensively evaluated. For example, if the adsorbent bed becomes clogged, the function is affected by temperature fluctuations, and the adsorbent becomes agglomerated, all of these problems affect the overall operating efficiency and life of the apparatus. By comprehensively analyzing the monitoring data, the system can obtain accurate damage mode data for judging whether potential faults or damage exists in the equipment.
The method further comprises the steps of extracting the temperature change trend of the pressure swing adsorption device based on the preset temperature range to conduct adsorption abnormality identification to obtain a leakage detection result, conducting heat transfer failure identification of the pressure swing adsorption device according to an internal structure, verifying the leakage detection result to obtain a leakage verification result, and taking the leakage verification result as the function monitoring result.
In particular, temperature variation is a very critical parameter in pressure swing adsorption units, as temperature directly affects the efficiency of the adsorption and desorption processes. The system monitors according to a preset temperature range, and if the temperature change trend exceeds a preset normal range, the system indicates that an abnormal condition may exist. For example, when the apparatus is operating, the temperature will typically vary with the progress of adsorption and desorption, and if the temperature varies too fast or too slow, it may be that gas leakage during adsorption causes abnormal heat exchange. By extracting the temperature change trend of the equipment, the system can identify whether adsorption abnormality exists or not, and a leakage detection result is generated according to the identification result.
The internal structure of the pressure swing adsorption apparatus, in turn, affects its heat transfer efficiency. If the heat transfer system inside the apparatus has defects or poor design, uneven temperature distribution or low heat transfer efficiency may result, thereby affecting the performance of the whole adsorption process. By analyzing the internal structure of the device, the system can identify whether there is a poor heat transfer. Poor heat transfer may exacerbate the leakage problem of the device, and therefore, verification of the leak detection results in the previous step is required. If the device has heat transfer problems, the leak detection results may not be accurate. By verifying the leak detection results, the system can obtain a more accurate leak verification result, ensuring that the device has a true leak problem.
Finally, the leakage verification result is one of the important bases for equipment health monitoring. The leakage verification result can not only confirm whether the leakage problem occurs in the equipment, but also reflect the overall functional state of the equipment. If the leakage verification result indicates that the device has a leakage problem, the function of the device may be seriously affected, resulting in a decrease in the working efficiency or a decrease in the safety. Therefore, the leakage verification result is directly used as a function monitoring result, and a judgment basis for whether the equipment is normally operated is provided.
The health state evaluation method comprises the steps of obtaining health state influence based on the damage mode data, configuring damage weights, carrying out weighted calculation on the damage mode data according to the damage weights to obtain health state scores, and taking the health state scores as health evaluation results.
Specifically, in the condition monitoring of the pressure swing adsorption apparatus, the damage pattern data reflects the health status of the various parts of the apparatus. For example, different components of the apparatus, such as adsorbent beds, valves, piping, etc., may experience different types of damage during long-term operation. Each damage pattern may have a different impact on the overall health of the device, where we need to configure the damage weights according to the specific impact of each damage pattern. The injury weight refers to the degree of importance of different types of injury in assessing the health status of the device. If a certain impairment mode has a greater impact on the performance of the device, its impairment weight will be higher. By acquiring these damage pattern data and their corresponding effects, we can be helped to more accurately assess the health status of the device.
Based on the configured impairment weights, we will weight the data for each impairment mode. The process of weighting calculation is to multiply the data of each damage pattern by its corresponding damage weight and then sum the results. By doing so, we can derive a comprehensive health status score that reflects the overall health of the device. For example, if a component has a high weight of damage and the component is damaged to a higher degree, the component will have a greater impact on the health score, thereby degrading the health score of the device. By means of the weighting mode, the health status score can comprehensively reflect the health status of each component of the equipment.
Finally, the health state score obtained through weighted calculation is a health evaluation result, and provides an important basis for equipment maintenance. This score can help the manager determine the current health of the device and decide whether repair or replacement of the component is needed. For example, if the health status score is lower, indicating that the device is more damaged, repair or inspection is needed, while if the score is higher, indicating that the device is good, immediate intervention may not be needed. The health assessment results provide quantitative reference basis for equipment management through the scoring system.
