Description

Technical Field

[0001] The present application relates to the field of hydrogen production by electrolysis, and more specifically, to a molecular sieve processing method, device, equipment and storage medium for a hydrogen production system. Background Art

[0002] In the process of producing hydrogen by electrolysis of water, special attention needs to be paid to the collection of hydrogen to ensure the safety of the hydrogen production process. In the current technology of producing hydrogen by electrolysis of water, molecular sieves are set up during the collection and transportation of hydrogen to filter impurities in hydrogen to improve the purity of hydrogen, thereby ensuring safety and improving the quality of hydrogen production.

[0003] As the molecular sieve is used for a longer time, its filtering capacity decreases and it is necessary to clean the molecular sieve. The existing cleaning method is single and it is difficult to ensure the cleaning effect of the molecular sieve. Summary of the invention

[0004] The embodiments of the present application provide a molecular sieve processing method, device, equipment and storage medium for a hydrogen production system, so as to at least solve the technical problem that it is difficult to ensure the cleaning effect of the molecular sieve.

[0005] According to a first aspect of an embodiment of the present application, a molecular sieve treatment method for a hydrogen production system is provided, the method comprising:

[0006] Get the color parameters and humidity parameters of the molecular sieve;

[0007] Determine a color change according to the color parameter and determine a humidity change according to the humidity parameter;

[0008] A target cleaning method for the molecular sieve is determined based on the color change and the humidity change.

[0009] M240486CNI-Pre-examination-Shanghai2024-11486

[0010] By adopting this embodiment, the molecular sieve can filter various types of impurities, such as oxygen, water, hydrogen sulfide, carbon dioxide, etc. When impurities remain in the molecular sieve, the color of the molecular sieve will change. Therefore, by determining the color change, the filtering condition of the molecular sieve on the impurities can be known, and the humidity change condition can reflect the filtering condition of the molecular sieve on the water. Based on the color change condition, the filtering condition of the molecular sieve on all impurities can be known, and based on the humidity change condition, the filtering condition of the water can be known, so as to know the water content in the impurities, thereby determining the target cleaning method, which is beneficial to mainly clean the water in the molecular sieve when there is more water in the impurities, and mainly clean other impurities when there is less water in the impurities, which helps to improve the cleaning effect of the molecular sieve.

[0011] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the color change condition includes a color change rate, and the humidity change condition includes a humidity change rate;

[0012] The method of determining a target cleaning method of the molecular sieve based on the color change and the humidity change includes:

[0013] The target cleaning method is determined according to the difference between the color change rate and the humidity change rate.

[0014] With this implementation, the color change rate can reflect the filtering of all impurities of the molecular sieve. When the color change rate is large, it proves that the amount of impurities filtered by the molecular sieve has increased; the humidity change rate can reflect the filtering of water by the molecular sieve. When the humidity change rate is large, it proves that the amount of water filtered by the molecular sieve has increased. Therefore, when the difference between the color change rate and the temperature change rate is known, the amount of water in all impurities filtered by the molecular sieve can be known, so that the appropriate target cleaning method can be determined, which improves the accuracy of the target cleaning method and its adaptability to the actual situation of the molecular sieve.

[0015] In combination with the first aspect, in an optional implementation of the embodiment of the present application, determining the target cleaning method according to the difference between the color change rate and the humidity change rate includes:

[0016] Calculating the ratio or difference between the color change rate and the temperature change rate to obtain a difference value;

[0017] If the difference value exceeds the preset difference threshold, the combined cleaning method is determined as the target M240486CNI-Preliminary-Shanghai2024-11486

[0018] Standard cleaning method, wherein the combined cleaning method includes mechanized cleaning and chemical cleaning;

[0019] If the difference value does not exceed the difference threshold, the drying cleaning method is determined as the target cleaning method.

[0020] With this implementation, the target cleaning methods include a combined cleaning method and a drying cleaning method. Different cleaning methods are used to deal with different impurity conditions of the molecular sieve, which helps to improve the cleaning effect of the molecular sieve.

[0021] In combination with the first aspect, in an optional implementation of the embodiment of the present application, the target cleaning method includes a combined cleaning method and a drying cleaning method;

[0022] The method further comprises:

[0023] If the target cleaning method is the combined cleaning method, the molecular sieve is first subjected to at least one of backflushing, chemical treatment, ultrasonic treatment and microwave radiation, and then the molecular sieve is dried;

[0024] If the target cleaning method is the drying cleaning method, the molecular sieve is subjected to the drying treatment;

[0025] Wherein, the backflushing treatment includes backflushing the molecular sieve with an inert gas, the chemical treatment includes cleaning the molecular sieve with chemicals, and the drying treatment includes blowing the molecular sieve with a hot gas flow.

[0026] By adopting the present implementation method, a variety of cleaning methods are combined, which is beneficial to improving the cleaning effect of the molecular sieve.

[0027] In combination with the first aspect, in an optional implementation manner of the embodiment of the present application, the method further includes:

[0028] If the target cleaning method is the drying cleaning method, the molecular sieve is divided into a to-be-cleaned area and a filtering area according to the color parameter, wherein the to-be-cleaned area represents an area that needs to be cleaned, and the filtering area represents an area that can be filtered;

[0029] When the ratio of the sum of the areas of the to-be-cleaned areas in the half area of ​​the molecular sieve to the sum of the areas of all the to-be-cleaned areas exceeds a preset threshold value, the molecular sieve is controlled to rotate 180 degrees and

[0030] The half area is dried.

[0031] By adopting this implementation method, not only can the cleaning method suitable for the molecular sieve be determined according to the color parameters, but also the area to be cleaned can be judged. When the area to be cleaned is concentrated on one side of the molecular sieve, it proves that the hydrogen is mainly in contact with one side of the molecular sieve. At this time, by rotating the molecular sieve, the filtration area of ​​the molecular sieve can be used to continue filtering the hydrogen, extending the use time of the molecular sieve and not easily affecting the production progress of hydrogen. In addition, after the molecular sieve is rotated 180 degrees, since the area to be cleaned is not easy to contact with a large amount of hydrogen, other tools or methods can be used to directly dry the molecular sieve, so that the molecular sieve can be cleaned while working, improving the hydrogen production effect.

[0032] In combination with the first aspect, in an optional implementation of the embodiment of the present application, determining the color change according to the color parameter and determining the humidity change according to the humidity parameter include:

[0033] Calculate the difference between the color parameters collected at two time nodes to obtain a first difference;

[0034] Calculate the first difference and compare it with the time interval between the two time nodes to obtain a color change rate and use the color change rate as the color change condition;

[0035] Calculating the difference between the humidity parameters collected at the two time nodes to obtain a second difference;

[0036] The second difference is calculated and compared with the time interval between the two time nodes to obtain a humidity change rate and the humidity change rate is used as the humidity change condition.

[0037] By adopting this implementation method, the process of determining the color change and humidity change is mainly a calculation process, and the calculation process is simple, which is conducive to improving the efficiency of determining the target cleaning method and reducing the occupation of computing resources.

[0038] In combination with the first aspect, in an optional implementation of the embodiment of the present application, before the molecular sieve is cleaned by the target cleaning method, the method further includes:

[0039] Determining the cleaning time of the molecular sieve according to the change of the color change rate;

[0040] When the color change rate gradually increases, the cleaning time of the molecular sieve is delayed, and when the color change rate gradually decreases, the cleaning time of the molecular sieve is advanced. The cleaning time of the molecular sieve is preset.

[0041] M240486CNI-Pre-examination-Shanghai2024-11486

[0042] In this implementation, if the color change rate is getting faster and faster, it proves that the molecular sieve can still adsorb impurities. If the color change rate is getting smaller and smaller, it proves that the molecular sieve is difficult to adsorb impurities and tends to be saturated. Therefore, delaying or advancing the cleaning time of the molecular sieve according to the color change rate is conducive to extending the working time of the molecular sieve or cleaning the molecular sieve in time.

[0043] According to a second aspect of an embodiment of the present application, a molecular sieve processing device of a hydrogen production system is provided, which is included in a target server in a cloud platform, and the device includes:

[0044] An acquisition module, used to obtain the color parameters and humidity parameters of the molecular sieve;

[0045] a change module, used to determine a color change according to the color parameter and to determine a humidity change according to the humidity parameter;

[0046] A determination module is used to determine a target cleaning method of the molecular sieve based on the color change and the humidity change.

[0047] According to a third aspect of an embodiment of the present application, an electronic device is provided, the electronic device comprising a memory and a processor;

[0048] The memory is used to store computer programs;

[0049] The processor is used to execute the computer program to implement the steps of the method described above.

[0050] According to a fourth aspect of an embodiment of the present application, a computer-readable storage medium is provided, wherein the computer-readable storage medium stores a computer program, and when the computer program runs on a computer or a processor, the computer or the processor executes the steps of the method described above.

[0051] The technical effects obtained in the above-mentioned second to fourth aspects are similar to the technical effects obtained by the corresponding technical means in the first aspect, and will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0056] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0057] It should be understood that the "plurality" mentioned in this article refers to two or more. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in order to facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first", "second" and so on are used to distinguish between the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first", "second" and so on do not limit the quantity and execution order, and the words "first", "second" and so on do not limit certain different

[0058] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.

[0059] First, the terms involved in the embodiments of the present application are introduced.

[0060] Molecular sieve is a crystalline material with a special pore structure, which is often used in the fields of impurity separation, catalytic reaction and molecular adsorption. In the process of water electrolysis to produce hydrogen, molecular sieve mainly plays the role of purifying hydrogen. Since the hydrogen and oxygen produced in the process of water electrolysis to produce hydrogen need to be effectively separated, and hydrogen M240486CNI-Pre-examination-Shanghai2024-11486

[0061] The gas needs to reach a certain purity standard, and molecular sieves come in handy. It can screen molecules of different sizes through its regular pore structure, thereby separating hydrogen and oxygen, and removing impurities in hydrogen, such as water and other gas molecules.

[0062] In the process of producing hydrogen by electrolysis of water, molecular sieves are mainly used to filter and purify hydrogen and remove impurities. Molecular sieves are usually used to remove the following impurities in this process:

[0063] Moisture: Since the electrolysis process is a gas-liquid coexistence, the hydrogen will contain saturated water. Molecular sieves have strong adsorption capacity and can effectively remove moisture from hydrogen;

[0064] Oxygen: Since the diaphragm cannot absolutely block the mutual penetration of hydrogen and oxygen, hydrogen may contain a small amount of oxygen. Molecular sieves can remove this impurity oxygen;

[0065] Hydrogen sulfide, ammonia: These impurities may come from the electrolyte or raw water, and molecular sieves can adsorb and remove these harmful gases;

[0066] Carbon dioxide: In some cases, if the feed water or electrolyte contains carbon dioxide, molecular sieves can also be used to remove carbon dioxide from hydrogen;

[0067] Other gases: such as nitrogen, methane, etc. Although these gases appear less frequently in the process of hydrogen production by water electrolysis, molecular sieves can also remove these impurities through their pore size selective adsorption characteristics.

[0068] The above introduces the terms involved in the embodiments of the present application. According to the research of the inventors of the present application, in the process of hydrogen production by PEM electrolyzer, the cleaning method of the molecular sieve is relatively fixed and single, and it is difficult to ensure the cleaning effect of the molecular sieve.

[0069] Based on this, the present application embodiment provides a molecular sieve treatment method for a hydrogen production system, referring to Figure 1 The schematic flow diagram of the molecular sieve treatment method for the hydrogen production system shown is a schematic flow diagram of the molecular sieve treatment method for the hydrogen production system, and the method includes the following treatment process.

[0070] S100, obtaining color parameters and humidity parameters of the molecular sieve.

[0071] In one embodiment, a camera can be used to photograph the molecular sieve to obtain an image containing the color of the molecular sieve, and then the color parameters of the molecular sieve can be obtained using image analysis technology or pixel recognition technology. Preferably, the color parameters include pixel parameters corresponding to each point of the molecular sieve.

[0072] M240486CNI-Pre-examination-Shanghai2024-11486

[0073] In one embodiment, the humidity parameter may be acquired by using a humidity sensor, which is not specifically limited in this embodiment.

[0074] It should be noted that the color parameters and humidity parameters can be obtained in multiple groups. That is to say, at the same time node, the color parameters and humidity parameters of the molecular sieve at this time are obtained respectively, and the color parameters and humidity parameters of the time node are taken as the same group, and so on, the color parameters and humidity parameters corresponding to multiple time nodes are obtained. So that in the subsequent calculation process, the color parameters and humidity parameters of the same group can be calculated, the color parameters of different groups can be calculated, and the humidity parameters of different groups can be calculated.

[0075] S102: Determine a color change according to the color parameter and determine a humidity change according to the humidity parameter.

[0076] The color change refers to the change value of the color of the molecular sieve, which can be the value of the color change degree or the value of the color change speed, and this embodiment does not make specific restrictions on this. The humidity change refers to the change value of the humidity of the molecular sieve, which can be the value of the humidity change degree or the value of the humidity change speed, and this embodiment does not make specific restrictions on this.

[0077] Since the color parameters include pixel parameters of multiple points of the molecular sieve, when determining the color change, the pixel parameters of the same point obtained at two time nodes can be subtracted, and then the difference values ​​of all points of the molecular sieve can be averaged to obtain the color change. In addition, the pixel parameters of several points of the molecular sieve can also be subtracted to obtain the color change, which is not specifically limited in this embodiment.

[0078] Similarly, the humidity change can be determined using the humidity parameters of the entire molecular sieve, or using the humidity parameters of multiple points of the molecular sieve, which is not specifically limited in this embodiment.

[0079] Preferably, when determining the color change, the color change value of each point of the molecular sieve is first calculated, and then the average value of the color change values ​​of all points is taken as the color change. Wherein, the color change value can be a color change degree value (that is, the size of the color difference) or a color change speed value (that is, the size of the color difference change per unit time).

[0080] S104. Determine the molecular sieve based on the color change and the humidity change. M240486CNI-Preliminary-Shanghai 2024-11486

[0081] Target cleaning method.

[0082] Different target cleaning methods are determined according to different color changes and humidity changes. In one embodiment, the target cleaning method can be determined by means of a preset table. Specifically, a table is preset, and the table contains a variety of cleaning methods, and different cleaning methods correspond to color changes and humidity changes. When it is necessary to determine the target cleaning method, the cleaning method that matches the humidity change and color change in the table can be used as the target cleaning method. In other embodiments, different target cleaning methods can be determined according to the actual color change and the humidity change by using neural network models, mathematical models, etc., and this embodiment does not specifically limit this.

[0083] It should be noted that the target cleaning method is one of the existing cleaning methods.

[0084] By adopting this embodiment, the molecular sieve can filter various types of impurities, such as oxygen, water, hydrogen sulfide, carbon dioxide, etc. When impurities remain in the molecular sieve, the color of the molecular sieve will change. Therefore, by determining the color change, the filtering condition of the molecular sieve on the impurities can be known, and the humidity change condition can reflect the filtering condition of the molecular sieve on the water. Based on the color change condition, the filtering condition of the molecular sieve on all impurities can be known, and based on the humidity change condition, the filtering condition of the water can be known, so as to know the water content in the impurities, thereby determining the target cleaning method, which is beneficial to mainly clean the water in the molecular sieve when there is more water in the impurities, and mainly clean other impurities when there is less water in the impurities, which helps to improve the cleaning effect of the molecular sieve.

[0085] In a possible embodiment of the present application, the color change condition includes a color change rate, and the humidity change condition includes a humidity change rate;

[0086] The method of determining a target cleaning method of the molecular sieve based on the color change and the humidity change includes:

[0087] The target cleaning method is determined according to the difference between the color change rate and the humidity change rate.

[0088] The difference size is the difference between the color change rate and the humidity change rate. In one embodiment, the absolute value can be taken after the difference is calculated to ensure that the calculation result is positive.

[0089] For ease of understanding, the color change rate characterizes the speed at which the color of the molecular sieve changes, that is, M240486CNI-Pre-examination-Shanghai 2024-11486

[0090] The greater the color change rate, the faster the molecular sieve color changes, and the reasons for the faster molecular sieve color change rate include that the molecular sieve filters out more impurities in the hydrogen, and the impurities filtered out can cause the molecular sieve color to change. The humidity change rate characterizes the rate of change of the molecular sieve humidity, that is, the greater the humidity change rate, the faster the molecular sieve humidity changes, and the reasons for the faster molecular sieve humidity change rate include that the molecular sieve filters out more water in the hydrogen.

[0091] Based on this, if the difference between the color change rate and the humidity change rate is large, it proves that the proportion of water in the impurities is small, and vice versa, it proves that the proportion of water in the impurities is large. Ideally, if all the impurities are water, the color change rate is equal to the humidity change rate.

[0092] Therefore, based on the above principle, a suitable cleaning method can be determined according to the difference between the color change rate and the humidity change rate.

[0093] With this implementation, the color change rate can reflect the filtering of all impurities of the molecular sieve. When the color change rate is large, it proves that the amount of impurities filtered by the molecular sieve has increased; the humidity change rate can reflect the filtering of water by the molecular sieve. When the humidity change rate is large, it proves that the amount of water filtered by the molecular sieve has increased. Therefore, when the difference between the color change rate and the temperature change rate is known, the amount of water in all impurities filtered by the molecular sieve can be known, so that the appropriate target cleaning method can be determined, which improves the accuracy of the target cleaning method and its adaptability to the actual situation of the molecular sieve.

[0094] Optionally, in an implementation of this embodiment, determining the target cleaning method according to the difference between the color change rate and the humidity change rate includes:

[0095] Calculating the ratio or difference between the color change rate and the temperature change rate to obtain a difference value;

[0096] If the difference value exceeds a preset difference threshold, a combined cleaning method is determined as the target cleaning method, wherein the combined cleaning method includes mechanized cleaning and chemical cleaning;

[0097] If the difference value does not exceed the difference threshold, the drying cleaning method is determined as the target cleaning method.

[0098] With this implementation, the target cleaning methods include combined cleaning methods and drying cleaning methods. Different cleaning methods can deal with different impurities in molecular sieves, which helps to improve the cleanliness of molecular sieves.

[0099] Therapeutic effect.

[0100] Optionally, when the difference value exceeds a preset alarm threshold, an alarm is issued.

[0101] Through the above content, when the difference value is large, it proves that the proportion of water in the impurities filtered by the molecular sieve is small, that is to say, the proportion of other impurities is large, such as oxygen. At this time, an alarm is issued, which makes it easy to monitor the impurity situation in the hydrogen and ensure the safety of hydrogen production.

[0102] Optionally, in an implementation of this embodiment, the target cleaning method includes a combined cleaning method and a drying cleaning method;

[0103] The method further comprises:

[0104] If the target cleaning method is the combined cleaning method, the molecular sieve is first subjected to at least one of backflushing, chemical treatment, ultrasonic treatment and microwave radiation, and then the molecular sieve is dried;

[0105] If the target cleaning method is the drying cleaning method, the molecular sieve is subjected to the drying treatment;

[0106] Wherein, the backflushing treatment includes backflushing the molecular sieve with an inert gas, the chemical treatment includes cleaning the molecular sieve with chemicals, and the drying treatment includes blowing the molecular sieve with a hot gas flow.

[0107] By adopting the present implementation method, a variety of cleaning methods are combined, which is beneficial to improving the cleaning effect of the molecular sieve.

[0108] Optionally, in an implementation of this embodiment, the method further includes:

[0109] If the target cleaning method is the drying cleaning method, the molecular sieve is divided into a to-be-cleaned area and a filtering area according to the color parameter, wherein the to-be-cleaned area represents an area that needs to be cleaned, and the filtering area represents an area that can be filtered;

[0110] When the ratio of the sum of the areas of the to-be-cleaned regions in the half region of the molecular sieve to the sum of the areas of all the to-be-cleaned regions exceeds a preset threshold value, the molecular sieve is controlled to rotate 180 degrees and the half region is dried.

[0111] In one embodiment, in order to dry the molecular sieve after the molecular sieve is rotated 180 degrees, M240486CNI-Preliminary-Shanghai 2024-11486

[0112] A circulating air duct is designed, in which a fan and a heating wire are installed. When the molecular sieve rotates 180 degrees, half of the molecular sieve is separated from the hydrogen transport pipeline and enters the circulating air duct, thereby drying the half area, thereby eliminating the need to disassemble the molecular sieve.

[0113] By adopting this implementation method, not only can the cleaning method suitable for the molecular sieve be determined according to the color parameters, but also the area to be cleaned can be judged. When the area to be cleaned is concentrated on one side of the molecular sieve, it proves that the hydrogen is mainly in contact with one side of the molecular sieve. At this time, by rotating the molecular sieve, the filtration area of ​​the molecular sieve can be used to continue filtering the hydrogen, extending the use time of the molecular sieve and not easily affecting the production progress of hydrogen. In addition, after the molecular sieve is rotated 180 degrees, since the area to be cleaned is not easy to contact with a large amount of hydrogen, other tools or methods can be used to directly dry the molecular sieve, so that the molecular sieve can be cleaned while working, improving the hydrogen production effect.

[0114] Optionally, in an implementation of this embodiment, determining the color change according to the color parameter and determining the humidity change according to the humidity parameter include:

[0115] Calculate the difference between the color parameters collected at two time nodes to obtain a first difference;

[0116] Calculate the first difference and compare it with the time interval between the two time nodes to obtain a color change rate and use the color change rate as the color change condition;

[0117] Calculating the difference between the humidity parameters collected at the two time nodes to obtain a second difference;

[0118] The second difference is calculated and compared with the time interval between the two time nodes to obtain a humidity change rate and the humidity change rate is used as the humidity change condition.

[0119] By adopting this implementation method, the process of determining the color change and humidity change is mainly a calculation process, and the calculation process is simple, which is conducive to improving the efficiency of determining the target cleaning method and reducing the occupation of computing resources.

[0120] Optionally, in an implementation of this embodiment, before the molecular sieve is cleaned in the target cleaning manner, the method further includes:

[0121] Determining the cleaning time of the molecular sieve according to the change of the color change rate;

[0122] Among them, the color change rate gradually increases, the cleaning time of the molecular sieve is postponed, and the color change rate gradually decreases, the cleaning time of the molecular sieve is advanced, wherein, there is a preset M240486CNI-Pre-examination-Shanghai 2024-11486

[0123] Describe the cleaning time of the molecular sieve.

[0124] In one embodiment, a cleaning time of the molecular sieve is preset, and the current execution body automatically adjusts the preset cleaning time according to the color change rate.

[0125] In this implementation, if the color change rate is getting faster and faster, it proves that the molecular sieve can still adsorb impurities. If the color change rate is getting smaller and smaller, it proves that the molecular sieve is difficult to adsorb impurities and tends to be saturated. Therefore, delaying or advancing the cleaning time of the molecular sieve according to the color change rate is conducive to extending the working time of the molecular sieve or cleaning the molecular sieve in time.

For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments. The steps shown in the relevant flow chart can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flow chart, in some cases, the steps shown or described can be executed in an order different from that here. In other words, the order of steps described in the foregoing embodiments is only an example, and it is also within the scope of protection of the embodiments of the present application to reasonably adjust the order of steps based on the content of the embodiments of the present application.
