[0002] In the steelmaking process of steel production, the converter refines pig iron into molten steel, while simultaneously producing converter gas. To recover energy from and treat the converter gas in an environmentally friendly manner, it needs to be pressurized for storage and utilization.

[0003] Currently, converter gas is typically pressurized using a pressurization unit consisting of multiple identical compressors. When pressure adjustment is required, it is achieved by uniformly adjusting the load of each compressor. However, when the compressors in the pressurization unit are of different models, this pressure regulation method makes it difficult to coordinate the control of each compressor.

If the remaining pressure difference is less than the preset pressure, then the inlet switch butterfly valve of one of the second type of compressors that is not running in the compressor linkage system will be opened. Adjust the valve opening of the inlet regulating valve according to the remaining pressure difference to meet the target pressure value.

[0008] Optionally, the valve of the second type of press is an inlet switch butterfly valve, the second type of press is a fixed load press, and the corresponding pressure is a preset pressure; the step of controlling the valves of the first type of press and / or the second type of press based on the magnitude relationship further includes: If the target pressure value is less than the current pressure value, and the pressure difference between the target pressure value and the current pressure value exceeds the preset pressure threshold range, calculate the remaining pressure difference between the pressure difference and the preset pressure. If the remaining pressure difference is less than the preset pressure, then the inlet switch butterfly valve of one of the second type of compressors currently operating in the compressor linkage system is closed; Adjust the valve opening of the inlet regulating valve according to the remaining pressure difference to meet the target pressure value.

[0009] Optionally, the valve controlling the first type of compressor and / or the second type of compressor based on the size relationship further includes: If the remaining pressure difference is greater than the preset pressure, calculate the quotient and remainder of the pressure difference and the preset pressure; The corresponding number of inlet switch butterfly valves of the second type of press are opened or closed according to the quotient of the pressure difference and the preset pressure. Adjust the valve opening of the inlet regulating valve according to the remainder between the pressure difference and the preset pressure to meet the target pressure value.

[0010] Optionally, the method further includes the step of determining the preset pressure threshold range, the step comprising: When the first type of compressor is running under preset conditions, the current load of the first type of compressor is increased at a set rate; When the first type of compressor passes through the surge zone, record the opening degree of the first inlet regulating valve of the first type of compressor; When the current load of the first type of compressor reaches the rated current, record the opening degree of the second inlet regulating valve of the first type of compressor; The range between the opening degree of the first inlet regulating valve and the opening degree of the second inlet regulating valve is taken as the preset pressure threshold range.

[0011] Optionally, the method further includes: If the target pressure value is greater than the maximum pressure that the press linkage system can provide, an error signal is generated and fed back to the user terminal.

[0012] Secondly, embodiments of the present invention provide a compressor control device, applied to a controller of a compressor linkage system.

Based on the different relationships between the target and current pressure values, the valves of the first-type and / or second-type compressors are controlled to bring the compressor linkage system to the target pressure value. Because this invention can adjust only a single compressor to achieve the target pressure value, rather than uniformly adjusting the load of all compressors, it enables coordinated control of the pressure of different compressor models, enhancing the applicability of the entire compressor linkage system.

[0024] Traditional pressurizer linkage systems typically use parallel operation of the same type of equipment, and achieve pressure control by uniformly adjusting the load. However, the existing hierarchical control method for multiple pressurizers of the same type is difficult to coordinate when encountering pressurizers of different types (such as equipment with large differences in flow rate and power).

[0025] Based on the above, embodiments of the present invention provide a press control method, device, electronic equipment, and storage medium, which can effectively alleviate the above problems.

[0031] This invention provides a method for controlling a pressurizer, applied to a controller of a pressurizer linkage system. The pressurizer linkage system further includes multiple pressurizers, each connected in parallel via a gas inlet manifold and a gas outlet manifold. A valve is installed between each pressurizer and the gas inlet manifold. Each pressurizer includes at least one first-type pressurizer and at least one second-type pressurizer. The controller is communicatively connected to each pressurizer. The method includes, as follows: Figure 2 The following steps are shown: Step S110: Obtain the target pressure value in real time.

[0032] Step S120: When the target pressure value is obtained, determine the relationship between the target pressure value and the current pressure value of the pressurizer linkage system.

[0033] Step S130: Control the valves of the first type of press and / or the second type of press based on the size relationship, so that the press linkage system reaches the target pressure value.

[0034] In step S110, the target pressure value is acquired in real time.

[0035] like Figure 3 The diagram shows the structure of a pressurizer linkage system. In this system, one type-1 pressurizer and multiple type-2 pressurizers can be installed. When converter gas is diverted from the converter gas pipeline to the inlet pipelines of the parallel pressurizers, the type-1 and type-2 pressurizers pressurize the converter gas respectively. The pressurized gas is then transported to the converter gas holder for storage and finally supplied to users.

[0036] When the pressurizer linkage system is started, it can start at least one second-type pressurizer at rated power and start the first-type pressurizer at minimum power, based on the initial pressure value sent by the user through the user terminal, and open their respective inlet valves, so that the pressurizer linkage system can meet the initial pressure value. During the operation of the pressurizer linkage system, the controller acquires the target pressure value newly sent by the user through the user terminal in real time.

[0037] In step S120, when the target pressure value is obtained, the relationship between the target pressure value and the current pressure value of the press linkage system is determined.

[0038] If the controller acquires a new target pressure value, it will determine the relationship between the target pressure value and the current pressure value of the compressor linkage system. If the target pressure value is the first target pressure value acquired during this startup of the compressor linkage system besides the initial pressure value, then the current pressure value is the initial pressure value. The controller will calculate the relationship between the current pressure value and the target pressure value, such as whether the target pressure value is greater than the current pressure value, the target pressure value is less than the current pressure value, or the target pressure value is equal to the current pressure value.

[0039] Execute step S130, control the valves of the first type of press and / or the second type of press based on the size relationship, so that the press linkage system reaches the target pressure value.

[0040] After determining the relationship between the target pressure value and the current pressure value, the controller controls the valves of the first type of compressor and / or the second type of compressor based on the control strategy corresponding to different relationships, so that the compressor linkage system adjusts from the current pressure value to the target pressure value. For example, if the target pressure value is less than the current pressure value, the valve openings of the first and second type of compressors remain unchanged; if the target pressure value is greater than the current pressure value, the valve opening of the second type of compressor remains unchanged, while the valve opening of the first type of compressor is increased, and so on.

[0041] Optionally, the valve of the first type of press is an inlet regulating valve, and the control of the valves of the first type of press and / or the second type of press based on the size relationship includes: If the target pressure value is greater than or less than the current pressure value, and the pressure difference between the target pressure value and the current pressure value is within a preset pressure threshold range, then the valve opening of the inlet regulating valve is adjusted so that the press linkage system reaches the target pressure value.

[0042] In one alternative implementation, such as Figure 3 As shown, the valve of the first type of compressor can be set as an inlet regulating valve. If the target pressure value is greater than the current pressure value, and the pressure difference between the target pressure value and the current pressure value is within the preset pressure threshold range of the inlet regulating valve, the power of the second type of compressor remains unchanged, and the compressor linkage system reaches the target pressure value only by changing the valve opening of the inlet regulating valve.

[0043] The method further includes the step of determining the preset pressure threshold range, the step including: When the first type of compressor is running under preset conditions, the current load of the first type of compressor is increased at a set rate.

[0044] When the first type of press passes through the surge zone, record the opening degree of the first inlet regulating valve of the first type of press.

[0045] When the current load of the first type of press reaches the rated current, record the opening degree of the second inlet regulating valve of the first type of press.

[0046] The range between the opening degree of the first inlet regulating valve and the opening degree of the second inlet regulating valve is taken as the preset pressure threshold range.

[0047] When the press operates with automatic load adjustment, it is necessary to implement anti-surge and anti-overload protection during the automatic load adjustment process. Therefore, as an optional implementation method, the preset pressure threshold range can be determined in the following way.

[0048] Under preset conditions (such as conveying media in normal production), the current load of the first type of compressor is gradually increased at a pre-set rate. When the first type of compressor passes through the surge zone, the opening of the first inlet regulating valve of the first type of compressor is recorded, which is the lower limit valve opening of the preset pressure threshold range. The current load of the first type of compressor continues to increase. When the current load of the first type of compressor reaches its rated current, the opening of the second inlet regulating valve of the first type of compressor at this time is recorded and used as the upper limit valve opening of the preset pressure threshold range.

[0049] Optionally, the valve of the second type of press is an inlet switch butterfly valve, the second type of press is a fixed load press, and the corresponding pressure is a preset pressure; the step of controlling the valves of the first type of press and / or the second type of press based on the magnitude relationship further includes: If the target pressure value is greater than the current pressure value, and the pressure difference between the target pressure value and the current pressure value exceeds the preset pressure threshold range, calculate the remaining pressure difference between the pressure difference and the preset pressure.

[0050] If the remaining pressure difference is less than the preset pressure, then the inlet switch butterfly valve of an unoperated second-type compressor in the compressor linkage system will be opened.

[0051] Adjust the valve opening of the inlet regulating valve according to the remaining pressure difference to meet the target pressure value.

[0052] As another alternative implementation method, such as Figure 3 As shown, the valve of the second type of press can be set as an inlet switch butterfly valve. That is, the second type of press is set as a fixed load press. When the pressure of the second type of press is adjusted, the inlet switch butterfly valve of the second type of press can only be opened or closed.

[0053] In this embodiment of the invention, if the target pressure value is greater than the current pressure value, and the pressure difference between the target pressure value and the current pressure value exceeds the preset pressure threshold range, it is considered that even if the inlet regulating valve of the currently activated first type of press is adjusted to the maximum opening corresponding to the preset pressure threshold range, it cannot meet the target pressure value.

[0054] Therefore, the controller can first calculate the difference between the pressure difference and the preset pressure of the second type of compressor, i.e., the remaining pressure difference. If the remaining pressure difference is less than the preset pressure, the controller can simply start another second type of compressor with a fixed load to meet the target pressure value. After starting the new second type of compressor, the pressure value of the compressor linkage system is the current pressure value plus the preset pressure. At this point, it is only necessary to adjust the valve opening of the inlet regulating valve of the first type of compressor according to the remaining pressure difference between the pressure difference and the preset pressure to meet the target pressure value.

[0055] For example, if the current pressure value is 10 kPa, the target pressure value is 15 kPa, the preset pressure is 3 kPa, and the preset pressure threshold range is 0.5~3 kPa.

[0056] Calculations show that the pressure difference is 5 kPa, and the remaining pressure difference is 2 kPa. At this point, starting an additional second-type press will allow the press linkage system to reach 13 kPa. Then, by adjusting the valve opening of the inlet regulating valve of the first-type press, the remaining 2 kPa pressure can be met, allowing the press linkage system to reach the target pressure value of 15 kPa.

[0057] Optionally, the valve of the second type of press is an inlet switch butterfly valve, and the second type of press is a fixed load press, with the corresponding pressure being a preset pressure. The method of controlling the valves of the first type of press and / or the second type of press based on the magnitude relationship further includes: If the target pressure value is less than the current pressure value, and the pressure difference between the target pressure value and the current pressure value exceeds the preset pressure threshold range, calculate the remaining pressure difference between the pressure difference and the preset pressure.

[0058] If the remaining pressure difference is less than the preset pressure, then the inlet switch butterfly valve of one of the second-type compressors currently operating in the compressor linkage system is closed.

[0059] Adjust the valve opening of the inlet regulating valve according to the remaining pressure difference to meet the target pressure value.

[0060] Similar to the case where the target pressure value is greater than the current pressure value, if the target pressure value is less than the current pressure value, and the pressure difference between the target pressure value and the current pressure value exceeds the preset pressure threshold range, then it is considered that even if the inlet regulating valve of the currently activated first type of compressor is adjusted to the minimum opening corresponding to the preset pressure threshold range, it will not be able to meet the target pressure value.

[0061] Therefore, the controller can first calculate the remaining pressure difference between the pressure difference and the preset pressure of the second type of compressor. If the remaining pressure difference is less than the preset pressure, the controller can meet the target pressure value by shutting down one fixed-load second type of compressor. After shutting down one second type of compressor, the pressure value of the compressor linkage system is the current pressure value minus the preset pressure. At this time, it is only necessary to reduce the valve opening of the inlet regulating valve of the first type of compressor according to the remaining pressure difference between the pressure difference and the preset pressure to meet the target pressure value.

[0062] Optionally, the valve controlling the first type of compressor and / or the second type of compressor based on the size relationship further includes: If the remaining pressure difference is greater than the preset pressure, calculate the quotient and remainder of the pressure difference and the preset pressure.

[0063] The corresponding number of inlet switch butterfly valves of the second type of press are opened or closed according to the quotient of the pressure difference and the preset pressure.

[0064] Adjust the valve opening of the inlet regulating valve according to the remainder between the pressure difference and the preset pressure to meet the target pressure value.

[0065] If the remaining pressure difference is greater than the preset pressure, it is considered that opening or closing one new type-two press will still not meet the target pressure value. In this case, the quotient and remainder of the pressure difference and the preset pressure can be calculated. The number of inlet butterfly valves of the type-two presses to be opened or closed is determined based on the multiple by which the pressure difference exceeds the preset pressure. The remaining remainder can be satisfied by adjusting the valve opening of the inlet regulating valve of the type-one press.

[0066] For example, if the current pressure value is 10 kPa, the target pressure value is 20 kPa, the preset pressure is 3 kPa, and the preset pressure threshold range is 0.5~3 kPa.

[0067] The calculation shows that the pressure difference is 10 kPa and the remaining pressure difference is 7 kPa. At this time, the quotient of the calculated pressure difference and the preset pressure is 3 and the remainder is 1. Then, three additional second-type presses are turned on, and the valve opening of the inlet regulating valve of the first-type press is adjusted to meet the remaining 1 kPa pressure, so that the press linkage system reaches the target pressure value of 20 kPa.

[0068] Optionally, the method further includes: if the target pressure value is greater than the maximum pressure that the pressurizer linkage system can provide, generating an error signal to feed back to the user terminal.

[0069] If the target pressure value obtained by the controller is greater than the maximum pressure that the press linkage system can provide (i.e., all second-type presses are activated and the inlet regulating valves of the first-type presses are opened to their maximum opening), and the target pressure value still cannot be met, the controller generates an error signal and sends it back to the user terminal to inform the user that the target pressure value cannot be met and that the target pressure value needs to be re-entered.

[0070] Based on the same inventive concept, such as Figure 4 As shown in the figure, an embodiment of the present invention provides a compressor control device 300, which is applied to a compressor linkage system. The compressor linkage system further includes multiple compressors, each compressor being connected in parallel through a gas inlet manifold and a gas outlet manifold. A valve is respectively installed between each compressor and the gas inlet manifold. The compressors include at least one first-type compressor and at least one second-type compressor. The controller is communicatively connected to each compressor. The compressor control device 300 includes: The target pressure value acquisition unit 301 is used to acquire the target pressure value in real time.

[0071] The calculation unit 302 is used to determine the relationship between the target pressure value and the current pressure value of the press linkage system when the target pressure value is obtained.

[0072] The press control unit 303 is used to control the valves of the first type of press and / or the second type of press based on the size relationship, so that the press linkage system can reach the target pressure value.

[0073] Regarding the aforementioned press control device 300, the specific functions of each unit have been described in detail in the embodiments of the press control method provided in this specification, and will not be elaborated upon here.

[0074] Based on the same inventive concept, embodiments of this invention provide a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of any of the methods of the aforementioned press control method.

[0075] The present invention has at least the following beneficial effects: By configuring at least one first-type and at least one second-type compressor in the compressor linkage system, when a target pressure value sent by the user terminal is received, the system compares the target pressure value with the current pressure value of the compressor linkage system. Based on the different relationships between the target and current pressure values, the valves of the first-type and / or second-type compressors are controlled to bring the compressor linkage system to the target pressure value. Because this invention can adjust only a single compressor to achieve the target pressure value, rather than uniformly adjusting the load of all compressors, it enables coordinated control of the pressure of different compressor models, enhancing the applicability of the entire compressor linkage system.
