Description

Technical Field

[0001] The present invention relates to the field of gas filtration, and in particular to an operation and maintenance method, device, equipment and readable storage medium for filtering and separating equipment. Background Art

[0002] Filtration and separation equipment uses physical methods to separate aerosols from the air, producing clean air. External dust-laden air passes through a filter cartridge (built into the filtration and separation equipment) and is converted into clean air. The clean air is then transported to downstream equipment, enabling the production, delivery, and utilization of clean air. The condition of the filter cartridge directly determines the filtration effectiveness of the filtration and separation equipment. However, related technologies fail to promptly detect poor filter cartridge condition, potentially causing the filtration and separation equipment to operate even when the filter cartridge is in poor condition. This results in poor filtration effectiveness and potential damage to downstream equipment.

[0054] The core of the present invention is to provide an operation and maintenance method, device, equipment and readable storage medium for filtering and separating equipment, pre-training a filter cartridge life prediction model, and then obtaining a real-time sensor data set (including the temperature and humidity data of the filter cartridge, the pressure difference value on the filter cartridge surface, the particle concentration at the inlet and outlet of the filter cartridge, and at least one of the filter cartridge outlet flow rate) through a preset sensor group during the operation of the filtering and separating equipment. The real-time sensor data set is then input into the pre-trained filter cartridge life prediction model to obtain the remaining life prediction value of the filter cartridge, and the prompter is controlled to prompt the remaining life prediction value, so as to promptly detect the situation where the filter cartridge is in poor condition and has insufficient life and replace it in time, thereby avoiding the filtering and separation equipment from operating when the filter cartridge is in poor condition, ensuring the filtering effect, and avoiding damage to the back-end equipment.

[0055] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0056] Please refer to Figure 1 , Figure 1 This is a flow chart of a first method for operating and maintaining a filtration and separation device provided by the present invention, which includes:

[0057] S101: During operation of the filtration and separation device, a real-time sensing data set is acquired through a preset sensor group, wherein the real-time sensing data set includes at least one of temperature and humidity data of a filter cartridge of the filtration and separation device, a pressure difference value on the surface of the filter cartridge, a particle concentration at an inlet and outlet of the filter cartridge, and a flow rate at an outlet of the filter cartridge;

[0058] Specifically, to better illustrate the embodiments of the present invention, please refer to Figure 2 , Figure 2 This is a structural diagram of an operation and maintenance device for a filtration and separation device provided by the present invention. Figure 2 Taking the filtration and separation equipment in the gas turbine as an example, Figure 2The reference numerals in the figures include: 1 is a gas turbine wheel, 2 is a compressor, 3 is a filter cartridge, 4 is a gateway, 5 is a processor, 6 is a temperature and humidity sensor, 7 is a first particle concentration sensor, 8 is an image sensor, 9 is a pressure difference sensor, 10 is a back-blow valve, 11 is a flow meter, and 12 is a second particle concentration sensor; the process flow is that the external air is filtered through the filter cartridge, flows into the compressor through the gas pipeline in the direction of the arrow for use. In the figure, 8 is an image sensor installed inside the filter separation device and captures images of the filter cartridge surface at a set time. A temperature and humidity sensor is installed at the air flow inlet of the filter separation device to collect the temperature, humidity, and atmospheric pressure parameters of the inlet air. In addition, a first particle concentration sensor is installed at the air flow inlet of the filter separation device to detect the particle concentration value of the inlet air. A differential pressure sensor is installed on the filter cartridge to monitor the differential pressure value on the filter cartridge surface during the filtration process. A flow meter 11 is installed in the air transmission pipeline at the rear end of the filter separation device to measure the flow rate and velocity of the clean air after filtration. A second particle concentration sensor is also installed in the air transmission pipeline to measure the particle concentration value of the clean air after filtration. After the above sensors collect data, they upload the data to the processor via the gateway. The processor analyzes the data and determines the predicted value of the remaining life of the filter cartridge. In subsequent embodiments, the processor can also control the backflush valve through the gateway to backflush the filter cartridge surface after determining the dust removal time, thereby achieving the purpose of cleaning the filter cartridge.

[0059] The combination of the above sensors may be a specific implementation of a preset sensor group.

[0060] Specifically, taking into account the technical problems in the above background technology, and considering that the relevant sensor data of the filter cartridge can reflect the remaining life of the filter cartridge, the embodiment of the present invention intends to pre-train a filter cartridge life prediction model, and then during the operation of the filtration and separation equipment, the remaining life prediction value of the filter cartridge is determined by the acquired real-time sensor data set and the filter cartridge life prediction model, so that the staff can perform filter cartridge maintenance based on the remaining life prediction value. Therefore, in this step, during the operation of the filtration and separation equipment, the real-time sensor data set can be obtained through the preset sensor group, so that it can be used as the data basis for subsequent steps.

[0061] The main body of the filtration and separation equipment is a self-cleaning filter with a large number of built-in filter cartridges. The dusty air outside is converted into clean air after passing through the filter cartridges. The clean air enters downstream equipment such as air compressors, realizing the production, transportation and utilization of clean air.

[0062] Specifically, the temperature and humidity data of the filter cartridge, the pressure difference on the filter cartridge surface, the particle concentration at the filter cartridge inlet and outlet, and the filter cartridge outlet flow rate can all reflect the filter cartridge status and filter cartridge life to a certain extent, and these sensor data can all be obtained through each sensor in the preset sensor group.

[0063] Of course, in addition to these data, the real-time sensing data set may also be of other types, which is not limited in the embodiment of the present invention.

[0064] S102: Inputting the real-time sensor data set into a pre-trained filter cartridge life prediction model to obtain a predicted value of the remaining life of the filter cartridge;

[0065] Specifically, a filter cartridge life prediction model can be obtained by training a machine learning algorithm using a historical sensor data set collected in advance during the full cycle operation of the filtration and separation equipment. The historical sensor data set can also be collected via a preset sensor group. During the training process, the historical sensor data set can be divided into a training set and a verification set. The filter cartridge life prediction model is obtained by training with the training set and verified by the verification set. The machine learning algorithm can be of various types, which are not limited in the embodiments of the present invention.

[0066] Specifically, the collected real-time sensor data set can be input into a pre-trained filter cartridge life prediction model to obtain a remaining life prediction value of the filter cartridge, which can accurately reflect the remaining life of the filter cartridge.

[0067] S103: The control prompter prompts the remaining life prediction value so that the filter cartridge can be maintained according to the remaining life prediction value.

[0068] Specifically, by prompting the remaining life prediction value through the prompter, the staff can obtain the remaining life prediction value in time and perform filter cartridge maintenance based on the remaining life prediction value. For example, when the remaining life prediction value is short, the filter cartridge can be repaired or replaced in time, thereby avoiding the filter cartridge working in a poor state, ensuring the filtering effect, and avoiding damage to the back-end equipment.

[0069] The prompter may be of various types, such as a display or a voice announcer, etc., which is not limited in the embodiment of the present invention.

[0070] The present invention provides an operation and maintenance method for a filtration and separation device. Considering that the relevant sensor data of the filter cartridge can reflect the remaining life of the filter cartridge, the present invention pre-trains a filter cartridge life prediction model. Then, during the operation of the filtration and separation device, a real-time sensor data set (including the temperature and humidity data of the filter cartridge, the pressure difference value on the surface of the filter cartridge, the particle concentration at the inlet and outlet of the filter cartridge, and at least one of the filter cartridge outlet flow rate) is obtained through a preset sensor group. The real-time sensor data set is then input into the pre-trained filter cartridge life prediction model to obtain a remaining life prediction value of the filter cartridge, and a prompter is controlled to prompt the remaining life prediction value, so as to timely discover the situation where the filter cartridge is in poor condition and has insufficient life and replace it in time, thereby avoiding the filtration and separation device from operating when the filter cartridge is in poor condition, ensuring the filtration effect, and avoiding damage to the back-end equipment.

[0071] Based on the above embodiment:

[0072] As an optional embodiment, after inputting the real-time sensor data set into a pre-trained filter cartridge life prediction model to obtain a predicted value of the remaining life of the filter cartridge, the operation and maintenance method of the filtration separation equipment further includes:

[0073] S201: Obtaining a current remaining life reference value of a filter cartridge of a filtration and separation device;

[0074] S202: Determine whether the deviation between the predicted value of the remaining life of the filter cartridge and the reference value of the remaining life is higher than a preset deviation;

[0075] S203: If it is higher, adjusting the parameters of the filter cartridge life prediction model according to the deviation of the remaining life prediction value relative to the remaining life reference value to improve the prediction accuracy.

[0076] Specifically, to better illustrate the embodiments of the present invention, please refer to Figure 3 , Figure 3 This is a flow chart of the second operation and maintenance method of the filtration and separation equipment provided by the present invention.

[0077] Specifically, considering that there are differences between the environmental factors and other factors of the filter cartridge to which the historical sensor data set used in the pre-trained filter cartridge life prediction model belongs and the environmental factors and other factors of the filter cartridge currently applied by the filter cartridge life prediction model, the prediction accuracy may also be reduced when making predictions using the real-time sensor data set. Therefore, in order to enable the filter cartridge life prediction model to more accurately predict the remaining life of the currently applied filter cartridge, in an embodiment of the present invention, after "inputting the real-time sensor data set into the pre-trained filter cartridge life prediction model to obtain the remaining life prediction value of the filter cartridge", the current remaining life reference value of the filter cartridge of the filtration and separation equipment (which is a relatively accurate remaining life value used as a reference for the filter cartridge) is obtained, and then it is determined whether the deviation of the remaining life prediction value of the filter cartridge from the remaining life reference value is higher than a preset deviation. If it is higher, it indicates that the prediction accuracy of the remaining life prediction value is poor, and the filter cartridge life prediction model needs to be optimized and improved. Therefore, the parameters of the filter cartridge life prediction model can be adjusted based on the deviation of the remaining life prediction value from the remaining life reference value to improve the prediction accuracy. If it is not higher, it indicates that the prediction accuracy of the remaining life prediction value is good, and there is no need to adjust the prediction accuracy of the remaining life prediction value.

[0078] The preset deviation degree may be set independently, for example, it may be a preset percentage of the prediction accuracy of the remaining life prediction value, the preset percentage may be 97%, etc., and the embodiment of the present invention does not limit this.

[0079] As an optional embodiment, obtaining the current remaining life reference value of the filter cartridge of the filtration separation device includes:

[0080] Get the current dust holding capacity of the filter cartridge;

[0081] Based on the dust holding capacity, the current remaining life reference value of the filter cartridge is determined according to a first relationship between the dust holding capacity and the remaining life reference value;

[0082] The first relation includes:

[0083] ;

[0084] Among them, t is the reference value of the remaining life of the filter cartridge, P0 is the pressure drop of the filter cartridge in the clean state, τ is the total operating time of the filtration separation equipment, P τ is the pressure drop of the filter cartridge at the current moment, B1 to B4 are fitting curve coefficients, Int is the intercept of the fitting curve, M τ It is the current dust holding capacity of the filter cartridge.

[0085] Specifically, considering that the first relationship between the dust holding capacity and the remaining life reference value can be used to efficiently and accurately determine the current remaining life reference value of the filter cartridge, the current dust holding capacity of the filter cartridge can be obtained in an embodiment of the present invention. Based on the dust holding capacity, the current remaining life reference value of the filter cartridge can be determined according to the first relationship between the dust holding capacity and the remaining life reference value.

[0086] Of course, in addition to the above specific forms, "obtaining the current remaining life reference value of the filter cartridge of the filtration separation equipment" can also be in other forms, such as obtaining a manually specified remaining life reference value through a human-computer interaction device, etc., which is not limited in the embodiments of the present invention.

[0087] As an optional embodiment, obtaining the current dust holding capacity of the filter cartridge includes:

[0088] The current dust holding capacity of the filter cartridge is determined through the second relationship;

[0089] The second relationship includes:

[0090] ;

[0091] q v is the air flow velocity of the filter cartridge, η is the filtration efficiency of the filter cartridge, t is the operation time, C m is the particle concentration in the filter cartridge, S f is the filtration area of the filter cartridge.

[0092] Specifically, considering that the second relationship of dust holding capacity can be used to efficiently and accurately determine the current dust holding capacity of the filter cartridge without disassembling the filter cartridge, the current dust holding capacity of the filter cartridge can be calculated through the second relationship in an embodiment of the present invention, and the operation time can be understood as the total operating time of the filter cartridge.

[0093] Of course, in addition to this specific method, the current dust holding capacity of the filter cartridge may also be determined by other methods, such as weighing, etc., which is not limited in this embodiment of the present invention.

[0094] As an optional embodiment, the operation and maintenance method of the filtration separation equipment further includes:

[0095] Through the current surface image of the filter cartridge, determine whether the current dust accumulation of the filter cartridge meets the dust removal standard;

[0096] If it is reached, the back-blowing valve is controlled to remove dust from the filter cartridge.

[0097] Specifically, in order to more accurately determine the dust removal timing of the filter cartridge, so as to better remove dust from the filter cartridge and avoid damage to the filter cartridge caused by the dust removal action, considering that there are significant differences in the surface images of the filter cartridge under different dust accumulation states, the embodiment of the present invention can determine whether the current dust accumulation amount of the filter cartridge meets the dust removal standard through the current surface image of the filter cartridge. If it meets the standard, the back-blowing valve can be controlled to remove dust from the filter cartridge, so that the dust removal timing can be accurately and reliably determined to trigger the dust removal action.

[0098] Of course, in addition to this method, there are many other types of methods for determining the timing of dust removal. For example, the dust removal action can be triggered when any one of the particle concentration downstream of the filter cartridge, the gas flow rate downstream of the filter cartridge, and the pressure difference value on the surface of the filter cartridge is within the corresponding abnormal range. The abnormal range corresponding to each indicator can be set independently. For example, the "abnormal range of the pressure difference value on the surface of the filter cartridge" can be greater than 300KPa, etc. The embodiments of the present invention are not limited here.

[0099] To better illustrate the embodiments of the present invention, please refer to Figure 4 , Figure 4 This is a logical structure diagram of an operation and maintenance method for a filtration and separation device provided by the present invention. Figure 4The preset sensor group in the system includes a differential pressure sensor, a temperature and humidity sensor, a particle concentration sensor, a flow meter, and an image sensor. The sensor data collected by the preset sensor group is transmitted via the gateway to the "life prediction module" and "dust removal timing judgment module" in the processor. In the "life prediction module," the real-time sensor data set can be input into the filter cartridge life prediction model to obtain a predicted remaining life value. The module then determines whether the deviation between the predicted remaining life value and the reference remaining life value exceeds a preset deviation. If so, the model (filter cartridge life prediction model) is optimized; if not, the predicted remaining life value is output. The "dust removal timing judgment module" can identify dust removal timing based on the filter cartridge surface image using the "dust removal timing recognition logic based on surface images" as described above. It can also identify dust removal timing using other types of sensor data using the dust removal timing recognition logic described above, which states that "dust removal action is triggered when any of the particle concentration downstream of the filter cartridge, the gas flow rate downstream of the filter cartridge, and the pressure differential value on the filter cartridge surface falls within the corresponding abnormal range." Regardless of the recognition method, once the dust removal timing is identified, the gateway can control the relay to activate, allowing the backflush valve to perform backflush dust removal.

[0100] In addition, after dust removal, the step of "S101: acquiring a real-time sensor data set through a preset sensor group during the operation of the filtration and separation equipment" can be retriggered to obtain the latest remaining life prediction value of the filter cartridge after dust removal.

[0101] As an optional embodiment, determining whether the current dust accumulation amount of the filter cartridge meets the dust removal standard based on the current surface image of the filter cartridge includes:

[0102] Obtaining the current surface image of the filter cartridge;

[0103] Determining whether the similarity between the current surface image and the pre-stored clean surface image of the filter cartridge is lower than a first preset threshold;

[0104] If it is lower than that, it is determined that the current dust accumulation of the filter cartridge meets the dust removal standard;

[0105] If it is not lower than, it is determined that the current dust accumulation of the filter cartridge does not meet the dust removal standard.

[0106] Specifically, to better illustrate the embodiments of the present invention, please refer to Figure 5 , Figure 5 The surface images of the filter cartridge provided by the present invention in different dust accumulation states are shown. Figure 5 From left to right in the figure are the clean surface image of the filter cartridge, the surface image of the filter cartridge with a small amount of dust accumulation, the surface image of the filter cartridge with a large amount of dust accumulation, and the surface image of the filter cartridge after dust removal.

[0107] Specifically, considering that the "similarity value between the current surface image of the filter cartridge and the clean surface image of the filter cartridge" can be used to efficiently and accurately determine the current dust accumulation level of the filter cartridge, thereby determining whether the dust removal standard is met, the embodiment of the present invention can obtain the current surface image of the filter cartridge, and determine whether the similarity between the current surface image and the pre-stored clean surface image of the filter cartridge is lower than a first preset threshold value. If so, it is determined that the current dust accumulation amount of the filter cartridge meets the dust removal standard. If not, it is determined that the current dust accumulation amount of the filter cartridge does not meet the dust removal standard.

[0108] The first preset threshold value can be set independently, for example, it can be set to 70%, etc., and the embodiment of the present invention does not limit this.

[0109] As an optional embodiment, the present invention includes:

[0110] Determining whether the similarity between the current surface image and the pre-stored clean surface image of the filter cartridge is greater than a second preset threshold;

[0111] If it is greater than, it is determined that the current dust accumulation in the filter cartridge meets the dust removal standard;

[0112] If it is not greater than, the filter cartridge is judged to be faulty and the indicator is controlled to give a prompt.

[0113] Specifically, considering that under normal circumstances, even if the amount of dust accumulation is large, the similarity between the current surface image and the clean surface image will not be too low, unless the filter cartridge is damaged, therefore, in an embodiment of the present invention, it is possible to determine whether the similarity between the current surface image and the pre-stored clean surface image of the filter cartridge is greater than a second preset threshold value. If not, the filter cartridge can be determined to be faulty and the indicator can be controlled to give a prompt so that the staff can intervene in time to repair the filter cartridge, thereby avoiding the filtration and separation equipment from operating when the filter cartridge is damaged, and thus avoiding damage to subsequent equipment by gases with poor filtration efficiency.

[0114] The second preset threshold value can be set independently, for example, it can be set to 30%, etc., and the embodiment of the present invention does not limit this.

[0115] Please refer to Figure 6 , Figure 6 This is a schematic structural diagram of an operation and maintenance device for a filtration and separation device provided by the present invention, wherein the operation and maintenance device for the filtration and separation device comprises:

[0116] an acquisition module 61 for acquiring a real-time sensor data set through a preset sensor group during operation of the filtration and separation device, wherein the preset sensor group includes: a plurality of sub-sensors, each sub-sensor being used to acquire sensor data related to the life of a filter cartridge in the filtration and separation device;

[0117] The prediction module 62 is used to input the real-time sensor data set into the pre-trained filter cartridge life prediction model to obtain the remaining life prediction value of the filter cartridge;

[0118] The control module 63 is used to control the indicator to indicate the remaining life prediction value so that the filter cartridge can be maintained according to the remaining life prediction value.
