Figure 1 As shown, the computer terminal may include one or more ( Figure 1 Only one is shown in the figure) a processor 102 (the processor 102 may include but is not limited to a processing device such as a microprocessor (Central Processing Unit, CPU) or a programmable logic device (Field Programmable Gate Array, FPGA)) and a memory 104 for storing data, wherein the above-mentioned computer terminal may also include a transmission device 106 and an input and output device 108 for communication functions. It can be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the above-mentioned computer terminal.

[0029] In this embodiment, a flow control method for a drying skid is provided, including but not limited to being used in a carbon dioxide storage capacity management model. Figure 2 is a flow chart of a flow control method of a drying skid according to an embodiment of the present application. Figure 2 As shown, the process includes the following steps S202-S208:

[0030] Step S202: obtaining a first amount of carbon dioxide to be input into the drying skid for drying;

[0031] Optionally, the first amount of carbon dioxide is carbon dioxide captured from exhaust gas from a factory or power plant, and can be determined based on the proportion of carbon dioxide in the exhaust gas and the exhaust gas flow rate.

[0032] Step S204: determining the drying parameters of each of the N drying towers included in the drying skid;

[0033] Optionally, multiple drying towers are provided in the drying skid, and each drying tower is controlled to perform a different drying stage, thereby greatly shortening the time for drying a fixed amount of carbon dioxide and improving the drying efficiency.

[0034] Step S206: Determine the amount of carbon dioxide that can be processed by each drying tower during the drying operation cycle according to the drying parameters; wherein the drying parameters include the amount of dry material present in each drying tower and the amount of carbon dioxide gas that can be introduced into each drying tower. By determining the drying parameters, the amount of gaseous matter that can be effectively processed by each drying tower can be identified, thereby avoiding a secondary drying process caused by inadequate processing.

[0035] Step S208: determining M target drying towers participating in drying in the drying skid according to the processing quantity and the first quantity, and performing flow control on the M target drying towers, wherein N and M are integers greater than 1, and M is less than or equal to N.

[0036] The above steps obtain the first quantity of carbon dioxide to be input into the drying skid for drying; determine the drying parameters of each drying tower among the N drying towers included in the drying skid; determine the processing quantity of the carbon dioxide by each drying tower during the drying operation cycle according to the drying parameters; determine the M target drying towers participating in the drying in the drying skid according to the processing quantity and the first quantity, and perform flow control on the M target drying towers, wherein N and M are integers greater than 1, and M is less than or equal to N. Through the above implementation, the problems of low efficiency and inflexibility in the drying process of carbon dioxide in the prior art are solved. By controlling different drying towers to execute different drying sub-processes respectively, the drying process is diverted, thereby improving the drying efficiency. At the same time, the processing method of non-single drying tower is used to avoid the influence of abnormal conditions on the overall capture system.

[0037] In an exemplary embodiment, before performing flow control on M target drying towers, it also includes: determining the P sub-cycles included in the drying operation cycle, and determining the function to be performed in the target drying tower in each sub-cycle, wherein the function includes at least one of the following: adsorption function, cooling function, regeneration function, and the P sub-cycles have the same cycle length; determining the target functions to be performed by the M target drying towers in the same period according to the P sub-cycles, wherein P is an integer greater than 2.

[0038] It can be understood that by dividing the drying operation cycle into P sub-cycles and determining the function to be performed in the target drying tower in each sub-cycle, the drying process can be better organized and arranged to improve the drying efficiency and quality. Each sub-cycle has the same cycle length, which can make the operation more regular and stable and reduce fluctuations in the drying process. This method can ensure that the target drying tower can complete the required functions in each time period, making the drying process more stable and efficient.

[0039] Optionally, the above-mentioned adsorption function refers to the adsorption of moisture in humid air into the interior of the drying tower by the adsorbent, thereby achieving the purpose of drying; the above-mentioned cooling function refers to the use of a cooling system to reduce the temperature inside the drying tower so that the adsorbent can restore its adsorption capacity; the above-mentioned regeneration function refers to the re-releasing of the adsorbed moisture by heating or other means, so that the adsorbent returns to a dry state.

[0040] In an exemplary embodiment, the target functions to be executed by M target drying towers in the same time period are determined according to P sub-cycles, including: when P is determined to be 3 and M is 3, it is determined that the first target drying tower among the M target drying towers is set to perform the adsorption function, the second target drying tower is set to perform the regeneration function, and the third target drying tower is set to perform the cooling function; or, it is determined that the first target drying tower among the M target drying towers is set to perform the regeneration function, the second target drying tower is set to perform the cooling function, and the third target drying tower is set to perform the adsorption function; or, it is determined that the first target drying tower among the M target drying towers is set to perform the cooling function, the second target drying tower is set to perform the adsorption function, and the third target drying tower is set to the regeneration function.

[0041] It is understandable that by performing different functions in turn in multiple target drying towers, through reasonable function allocation, the system's work efficiency and requirements can be effectively improved, ensuring that each target drying tower can play its maximum role. According to the characteristics and requirements of different functions, targeted tasks are allocated to avoid interference and conflict between functions, and improve the stability and reliability of the system.

[0042] In an exemplary embodiment, determining M target drying towers participating in drying in a drying skid according to the processing quantity and the first quantity includes: determining a target multiple between the processing quantity and the first quantity; rounding up the target multiple to obtain a target value; and determining the M target drying towers participating in drying in the drying skid based on the target value, wherein the target value is the same as the M.

[0043] It is understandable that the specific process of determining the M target drying towers participating in the drying in the drying skid according to the processing quantity and the first quantity includes determining the target multiple, rounding up to obtain the target value, and selecting M target drying towers to participate in the drying operation. Rounding up to determine the target value can more accurately determine the number of drying towers that need to be dried, avoiding waste of resources. It can also ensure the adequacy of the drying operation and ensure that all target drying towers are fully dried. This method can effectively improve the drying efficiency, ensure that all target drying towers are fully processed, and save resources and costs.

[0044] In an exemplary embodiment, flow control is performed on the M target drying towers, including: when determining the target functions that need to be performed by the M target drying towers at different time periods, matching corresponding pipeline control strategies for the target functions from a preset operation database, wherein the preset operation database contains multiple sets of pre-designed pipeline control strategies and associations with target drying towers and target functions; and adjusting the switching states of different valves in the drying skid according to the pipeline control strategies to control the actual processing quantity of the first amount of carbon dioxide entering different target drying towers.

[0045] It is understandable that by presetting the pipeline control strategy stored in the operation database, the appropriate pipeline control strategy can be quickly selected for each target drying tower, improving the efficiency and accuracy of the operation. At the same time, adjusting the switch status of different valves in the drying skid can achieve precise control of different target drying towers, ensuring that each target drying tower operates according to the preset target function, improving production efficiency and product quality.

[0046] In an exemplary embodiment, after determining the M target drying towers participating in drying in the drying skid according to the processing quantity and the first quantity, and performing flow control on the M target drying towers, it also includes: monitoring the real-time operating parameters of the M target drying towers during the flow control process, wherein the real-time operating parameters at least include: the pressure parameters of the target drying towers, the drying efficiency of the target drying towers; when the real-time operating parameters do not meet the preset standard operating parameters, sending an abnormal prompt information to the equipment management system where the drying skid is located, wherein the abnormal prompt information is used to indicate that the operation of the drying skid is abnormal and an operation and maintenance inspection is required; when the real-time operating parameters meet the preset standard operating parameters, recording the actual time consumed by the drying skid to process the first amount of carbon dioxide.

[0047] That is to say, after the flow rate of M target drying towers is controlled, their real-time operating parameters, including pressure and drying efficiency, are monitored. If the parameters are abnormal, a prompt message is sent for operation and maintenance inspection; if the parameters are normal, the actual duration of carbon dioxide consumption is recorded. Through the above operations, effective management and monitoring of the drying skid can be achieved to ensure stable operation of the equipment and product quality. At the same time, abnormal situations can be discovered and handled in a timely manner to improve production efficiency and equipment utilization. This method can help companies improve production efficiency, reduce losses, and enhance competitiveness.

[0048] Obviously, the embodiments described above are only some embodiments of the present application, not all embodiments. In order to better understand the above method, the above process is described below in conjunction with the embodiments, but it is not intended to limit the technical solutions of the embodiments of the present application, specifically:

[0049] An optional embodiment of the present application provides a flow control method for a drying skid to solve the problems of low efficiency and inflexibility in the drying process of carbon dioxide. The method can effectively control the flow and concentration of carbon dioxide and improve the efficiency of capture and storage.

[0050] Optionally, the flow control of the drying skid involves the following aspects:

[0051] First, drying technology: Drying technology can effectively remove moisture from the air, making the capture and storage of carbon dioxide more efficient and stable.

[0052] Second, pry flow control technology: pry flow control technology refers to adjusting the flow and concentration of carbon dioxide as needed to ensure the stability and controllability of the capture and storage process.

[0053] Third, management and control technology: Management and control technology refers to controlling the flow direction and speed of carbon dioxide through equipment such as pipes and valves to ensure its smooth capture and storage.

[0054] In practical applications, the flow control technology of the drying skid needs to combine the above technologies and be adjusted and optimized according to specific circumstances to achieve the best capture and storage effect.

[0055] Optional, Figure 3 It is a structural schematic diagram of a flow control system of a drying skid according to an embodiment of the present application; the above system at least includes a flow monitoring unit 32, a flow control unit 34, a data recording unit 36, and a safety protection unit 38.

[0056] Optionally, the flow monitoring unit 32 is mainly used to monitor the inlet and outlet flow of the drying skid and display the flow data in real time. By monitoring the flow in real time, problems can be discovered and adjusted in time to improve production efficiency.

[0057] Optionally, the flow control unit 34 mainly controls and adjusts the flow of the drying skid according to the real-time monitored flow data to ensure that the flow is stable and meets the requirements. In addition, the flow monitoring can also avoid the safety hazards caused by excessive or insufficient flow.

[0058] Optionally, the data recording unit 36 ​​is mainly used to record flow data to facilitate subsequent analysis and optimization operations. By analyzing the data records, the production process can be optimized to improve production efficiency and product quality.

[0059] Optionally, the safety protection unit 38 is mainly used in the event of abnormal flow or sudden events. The system will issue an alarm and take corresponding protection measures to ensure the safety of equipment and personnel.

[0060] As an optional implementation, a drying skid flow control adopts a three-tank type, that is, the three processes of adsorption, regeneration and cooling are carried out simultaneously, and automatically switched within a certain period. One drying tower adsorbs, and the other two drying towers regenerate and cool respectively. The specific working modes are as follows:

[0061] The first one is A adsorption, B regeneration, and C cooling. The adsorption function is realized by the first drying tower A. The regeneration function is performed by the second drying tower B, and the cooling function is performed by the third drying tower C.

[0062] The second method is to use A for regeneration, B for cooling, and C for adsorption. The regeneration function is performed by the first drying tower A. The cooling function is performed by the second drying tower B, and the regeneration function is performed by the third drying tower C.

[0063] The third type is A cooling, B adsorption, and C regeneration, where the cooling function is performed by the first drying tower A. The adsorption function is achieved by the second drying tower B, and the regeneration function is performed by the third drying tower C.

[0064] Optional, Figure 4 This is a schematic diagram of a flow control operation simulation of a drying skid according to an embodiment of the present application. The working mode is the first one mentioned above: A adsorption B regeneration C cooling. The specific process is as follows:

[0065] 1. Adsorption process: The carbon dioxide adsorption process is carried out in the drying tower A by controlling the relevant valves. During the adsorption process, the gas containing carbon dioxide passes through the adsorbent, usually activated carbon or molecular sieve and other materials, so that the carbon dioxide is adsorbed on the surface of the adsorbent, and the valves A01 and A02 corresponding to the drying tower A are opened. At the same time, the valves B01 and B02 corresponding to the drying tower B and the valves C01 and C02 corresponding to the drying tower C are controlled to be closed. Among them, the drying tower B has completed the adsorption and is waiting for regeneration; the drying tower C has completed the adsorption and regeneration and is waiting for cooling. The specific steps are as follows:

[0066] Step 1: The gas containing carbon dioxide enters through the bottom of the drying tower, passes through the packing layer, and comes into contact with the adsorbent (such as activated carbon or molecular sieve);

[0067] Step 2: Carbon dioxide is adsorbed on the surface of the adsorbent, and the gas passing through the packing layer is discharged at the top outlet of the drying tower, at which time the carbon dioxide content is reduced;

[0068] Step 3: After the carbon dioxide in the adsorbent reaches saturation, it needs to be regenerated to restore its adsorption capacity.

[0069] 2. Regeneration process: The carbon dioxide regeneration process is carried out in the drying tower B by controlling the relevant valves. In the regeneration process, the carbon dioxide in the adsorbent is desorbed by increasing the temperature or reducing the pressure, so that the adsorbent regains its adsorption capacity. Optionally, in order to save energy in actual applications, the dry regeneration electric heater can be combined with the auxiliary steam of the power plant to save the regeneration cost. The specific steps are as follows:

[0070] Step 1: Desorb the carbon dioxide from the adsorbent bed, usually by increasing the temperature or reducing the pressure.

[0071] Step 2: The desorbed carbon dioxide is discharged and the adsorbent recovers its adsorption capacity.

[0072] Step 3: The regenerated adsorbent can be used for the next round of adsorption process.

[0073] 3. Cooling process: The carbon dioxide cooling process is carried out in the drying tower C by controlling the relevant valves. The regenerated adsorbent needs to be cooled to the normal working temperature in order to resume the adsorption operation. During the cooling process, cooling water enters through the bottom of the drying tower to restore it to a suitable temperature and prepare for the next round of adsorption process. The specific steps are as follows:

[0074] Step 1: Pass cooling water through the adsorbent bed in drying tower C to reduce the adsorbent temperature.

[0075] Step 2: Lowering the adsorbent temperature helps prepare for the next round of adsorption process and ensure the stability and performance of the adsorbent.

[0076] Step 3: After cooling, the adsorbent can enter the next round of adsorption process.

[0077] Optionally, during the flow control process of the drying skid, the adsorption process needs to ensure sufficient contact of the adsorbent, and the adsorption effect can be enhanced by increasing stirring or increasing the gas flow rate.

[0078] Optionally, during the regeneration process, it is necessary to pay attention to controlling the temperature and flow rate of the regeneration gas to ensure that the regeneration gas can effectively remove the adsorbed substances in the adsorbent.

[0079] Optionally, during the cooling process, it is necessary to control the flow rate and temperature of cooling water or other cooling media to ensure that the adsorbent can be quickly cooled and restored to a temperature range suitable for adsorption.

[0080] In addition, during the entire flow control process, it is necessary to regularly monitor the performance of the adsorbent and the effect of flow control, and adjust the operating parameters in time to ensure the normal operation of the drying skid.

[0081] In summary, the optional embodiment of the present application, when it is determined that there are at least three drying towers, the adsorption function is realized by the first drying tower. The second drying tower is used to perform the regeneration function, and the third drying tower is controlled to perform the cooling function, so that when the above-mentioned at least three drying towers are used to dry carbon dioxide, the overall drying process is decomposed into multiple drying towers for separate execution, and the overall drying efficiency is improved through circulation, so that the drying process can be quantitatively continuous. Further, by adjusting the pipeline valve to control the first drying tower to enter the regeneration stage after the adsorption is completed, the second drying tower is switched from the regeneration stage to the cooling stage, and the third drying tower is switched from the cooling stage to the adsorption stage. By using three drying towers for synchronous operation, efficient carbon dioxide adsorption, regeneration and cooling can be achieved, and then continuous production can be achieved, which not only improves the processing efficiency of the entire system but also improves the stability and reliability of the processing. In addition, synchronous operation can also reduce processing time, save energy and cost.

[0082] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course it can also be implemented by hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of the present application, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, disk, CD), and includes a number of instructions for a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods of each embodiment of the present application.

[0083] In this embodiment, a flow control device for a drying skid is also provided, which is used to implement the above-mentioned embodiments and preferred implementation modes, and will not be repeated hereafter. As used below, the term "module" may be a combination of software and / or hardware that implements a predetermined function. Although the devices described in the following embodiments are preferably implemented in software, the implementation of hardware, or a combination of software and hardware, is also possible and conceivable.

[0084] Figure 5: is a structural block diagram of a flow control device of a drying skid according to an embodiment of the present application, the device comprising:

[0085] An acquisition module 52, for acquiring a first amount of carbon dioxide to be input into the drying skid for drying;

[0086] A first determination module 54 is used to determine the drying parameters of each of the N drying towers included in the drying skid;

[0087] A second determination module 56 determines the amount of carbon dioxide to be processed by each drying tower during a drying operation cycle according to the drying parameters;

[0088] The third determination module 58 determines M target drying towers participating in drying in the drying skid according to the processing quantity and the first quantity, and performs flow control on the M target drying towers, wherein N and M are integers greater than 1, and M is less than or equal to N.

[0089] Through the above device, the first quantity of carbon dioxide to be input into the drying skid for drying is obtained; the drying parameters of each drying tower in the N drying towers included in the drying skid are determined; the processing quantity of the carbon dioxide by each drying tower during the drying operation cycle is determined according to the drying parameters; the M target drying towers participating in the drying in the drying skid are determined according to the processing quantity and the first quantity, and the flow control of the M target drying towers is performed, wherein N and M are integers greater than 1, and M is less than or equal to N. Through the above implementation, the problems of low efficiency and lack of flexibility in the drying process of carbon dioxide in the prior art are solved.
