[0023] In some embodiments, optionally, Figure 1 As shown, a flow adjustment method for a gas cabinet is proposed, comprising:

[0024] Step S101, obtaining the gas demand volume of the gas demand end and the first volume of the gas tank, and obtaining the time interval of the operation of the steelmaking furnace.

[0025] In this embodiment, the gas holder is used to store the gas generated by the steelmaking furnace and transmit the gas to the gas demand end, wherein the gas demand end is the gas consumption end. The steelmaking furnace will generate gas during the steelmaking process. The gas holder can collect and store the gas generated by the steelmaking furnace. The output end of the gas holder is connected to the gas demand end, and can transmit the gas to the gas demand end.

[0026] Exemplarily, the steelmaking furnace may be a converter for steelmaking.

[0027] Obtain the gas demand volume of the gas demand end and the first volume of the gas tank, and obtain the time interval of the steelmaking furnace operation, wherein the gas demand volume is the volume of gas required by the gas demand end, the first volume is the rated volume of the gas tank, and the time interval is the time interval between multiple operations of the steelmaking furnace.

[0028] Illustratively, the first volume may be one thousand cubic meters.

[0029] Exemplarily, the gas demand volume may be five hundred cubic meters.

[0030] For example, the time interval may be a fixed one hour.

[0031] Step S102, when the steelmaking furnace delivers gas to the gas holder, the volume of the gas is detected to obtain a first volume of the gas.

[0032] In the process of the steelmaking furnace generating gas and delivering the gas to the gas holder, the volume of the gas is detected to determine a first volume of the gas, wherein the first volume is the volume of the gas generated by the steelmaking furnace.

[0033] Exemplarily, the main component of coal gas is carbon monoxide.

[0034] Exemplarily, a gas sensor is provided on the gas cabinet, and the volume of gas is detected by the gas sensor.

[0035] Step S103, adjusting the volume flow rate of gas delivered by the gas cabinet to the gas demand end according to the first capacity, the first volume, the gas demand volume and the time interval.

[0036] Based on the first capacity, the first volume, the gas demand volume and the time interval, the volume flow rate corresponding to the gas is determined, and according to the volume flow rate, the flow rate of gas delivered by the gasholder to the gas demand end is adjusted.

[0037] Among them, the volume flow rate is the volume flow rate of gas delivered by the gas tank to the gas demand end.

[0038] For example, when the gas demand volume is large and the first volume is small, the volume flow rate of gas delivered by the gasholder to the gas demand end can be reduced.

[0039] For example, when the gas demand volume is small and the first volume is large, the volume flow rate of gas delivered by the gasholder to the gas demand end can be increased.

[0040] Exemplarily, the volume flow rate of gas delivered by the gasholder to the gas demand end is adjusted so that the volume of gas stored in the gasholder is approximately half of the first volume, thereby ensuring the stability of the gasholder.

[0041] It should be noted that the volume flow rate of gas delivered by the gas tank to the gas demand end is determined based on multiple data such as the first capacity, the first volume, the gas demand volume and the time interval, thereby ensuring the accuracy of the volume flow rate data and further ensuring the accuracy of the volume flow rate regulation.

[0042] In addition, by accurately adjusting the volume flow of the gas, the efficiency of adjusting the gas flow can be improved, thereby reducing time costs.

[0043] The flow adjustment method of the gas holder in this embodiment adjusts the volume flow rate of gas delivered by the gas holder to the gas demand end according to the first capacity, the first volume, the gas demand volume and the time interval, thereby ensuring the data accuracy of the volume flow rate of the gas, and further ensuring the accuracy of the regulation of the volume flow rate, while improving the adjustment efficiency of the gas flow rate.

[0044] In some embodiments, optionally, a flow adjustment method of a gas holder is proposed, which adjusts the volume flow of gas delivered by the gas holder to the gas demand end according to the first capacity, the first volume, the gas demand volume and the time interval, including:

[0045] Step S201, when the first volume is smaller than the required gas volume, reducing the volume flow rate.

[0046] In this embodiment, when the first volume is smaller than the gas demand volume, it indicates that the gas demand at the gas demand end is greater than the gas generation of the steelmaking furnace, and the gas reserve inside the gas tank is maintained by continuously reducing the volume flow of the gas.

[0047] Exemplarily, the volume flow of the gas output from the gasholder is reduced by adjusting the gas output valve of the gasholder.

[0048] Step S202: when the product of the volume flow rate and the time interval is less than the first volume and the volume flow rate is equal to the first flow rate threshold, reduce the pressure on the gas to adjust the volume flow rate.

[0049] When the product of the volume flow and the time interval is less than the first volume and the volume flow is equal to the first flow threshold, it indicates that the volume flow of the gas output from the gasholder has been reduced to the first flow threshold, which is a critical value of the volume flow.

[0050] Exemplarily, the first flow threshold may be a minimum critical value that can be adjusted by the gas output valve.

[0051] Then, the volume flow of the gas is further reduced by reducing the pressure on the gas.

[0052] Exemplarily, a compressor may be provided on the pipeline between the gas tank and the gas demand end, and the compressor is used to reduce the pressure on the gas, thereby reducing the volume flow of the gas.

[0053] For example, by reducing the gas output valve of the gas cabinet to reduce the volume flow of the gas to a first flow threshold, in this case, the volume flow of the gas cannot be further reduced by reducing the gas output valve, but the volume flow of the gas can be further reduced by reducing the pressure on the gas by using a compressor.

[0054] Exemplarily, the amount of gas generated by a single furnace in a steel plant is Q1 (i.e., the first volume), the interval time is T, the cabinet capacity of the gas tank is V (i.e., the first volume), the after-machine pressure of the compressor is P, the delivery volume of the gas tank is v1 (i.e., the volume flow rate), and the coal conversion user usage is Q3 (i.e., the gas demand volume). When Q3>Q1, v1 is controlled so that v1×T<V. If v1 cannot be adjusted, P continues to be adjusted to control v1.

[0055] The flow adjustment method of the gas cabinet in this embodiment, after reducing the gas output valve of the gas cabinet to reduce the volume flow rate of the gas to a first flow threshold, reduces the pressure on the gas through a compressor, which can further reduce the volume flow rate of the gas, thereby ensuring the accuracy of regulating the volume flow rate of the gas.

[0056] In some embodiments, optionally, a flow adjustment method of a gas holder is proposed, which adjusts the volume flow of gas delivered by the gas holder to the gas demand end according to the first capacity, the first volume, the gas demand volume and the time interval, including:

[0057] Step S301, when the first volume is greater than the required gas volume, increasing the volume flow rate.

[0058] In this embodiment, when the first volume is equal to the gas demand volume, it indicates that the gas demand at the gas demand end is less than the gas generation of the steelmaking furnace, and the gas reserve inside the gas tank is maintained by continuously increasing the volume flow of the gas.

[0059] For example, the volume flow rate of the gas output from the gasholder is increased by increasing the gas output valve of the gasholder.

[0060] Step S302: when the product of the volume flow rate and the time interval is greater than the first volume and the volume flow rate is equal to the second flow rate threshold, increase the pressure of the gas to adjust the volume flow rate.

[0061] When the product of the volume flow and the time interval is greater than the first volume and the volume flow is equal to the second flow threshold, it indicates that the volume flow of the gas output from the gas cabinet has increased to the second flow threshold, and the second flow threshold is a critical value of the volume flow.

[0062] Exemplarily, the second flow threshold may be a maximum critical value that can be adjusted by the gas output valve.

[0063] Then, by increasing the pressure on the gas, the volume flow rate of the gas can be further increased.

[0064] For example, a compressor may be provided on the pipeline between the gas tank and the gas demand end, and the pressure of the gas may be increased by the compressor, thereby increasing the volume flow of the gas.

[0065] For example, by increasing the gas output valve of the gas cabinet to reduce the volume flow of the gas to the second flow threshold, in this case, the volume flow of the gas can no longer be prompted by adjusting the gas output valve, but the gas pressure can be increased by a compressor to further increase the volume flow of the gas.

[0066] Exemplarily, the amount of gas generated by a single furnace in a steel plant is Q1 (i.e., the first volume), the interval time is T, the capacity of the gas tank is V (i.e., the first volume), the pressure after the compressor is P, the delivery volume of the gas tank is v1 (i.e., the volume flow rate), and the amount used by coal users is Q3 (i.e., the gas demand volume). When Q3<Q1, v1 is controlled so that v1T>V. If v1 cannot be adjusted, P continues to be adjusted to control v1.

[0067] The flow adjustment method of the gas cabinet in this embodiment increases the volume flow rate of the gas by increasing the gas output valve of the gas cabinet to the second flow threshold, and then increases the pressure of the gas by a compressor, which can further increase the volume flow rate of the gas and ensure the accuracy of adjusting the volume flow rate of the gas.

[0068] In some embodiments, optionally, a method for adjusting the flow rate of a gas cabinet is proposed. After detecting the volume of the gas and obtaining a first volume of the gas, the method further includes:

[0069] Step S401, when the first volume is equal to the required gas volume, adjust the volume flow rate so that the gas volume stored in the gas tank is equal to the product of the first volume and the preset ratio.

[0070] In this embodiment, when the first volume is equal to the required gas volume, the volume flow rate of the gas output by the gasholder is adjusted so that the volume of gas stored in the gasholder is equal to the product of the first volume and the preset ratio.

[0071] Exemplarily, the amount of gas generated by a single furnace in a steel plant is Q1 (i.e., the first volume), the interval time is T, the cabinet capacity of the gas tank is V (i.e., the first volume), the after-machine pressure of the compressor is P, the delivery volume of the gas tank is v1 (i.e., the volume flow rate), and the coal-to-gas user usage is Q3 (i.e., the gas demand volume). When Q3=Q1, V is controlled to be in the middle cabinet position.

[0072] The flow adjustment method of the gas holder in this embodiment ensures that the volume of gas stored in the gas holder is equal to the product of the first volume and the preset ratio by adjusting the volume flow of the gas output by the gas holder when the first volume is equal to the gas demand volume, thereby ensuring the stability of the gas holder.

[0073] In some embodiments, optionally, a flow adjustment method for a gas tank is proposed, where a compressor is provided between the gas tank and a gas demand end, and the compressor can adjust the pressure of the gas to adjust the volume flow.

[0074] In this embodiment, a gas transmission pipeline between the gas tank and the gas demand end is provided with a compressor, which can pressurize the gas to adjust the volume flow.

[0075] Exemplarily, the compressor may be a gas compressor.

[0076] In some embodiments, optionally, a flow adjustment method for a gas cabinet is proposed, and the flow adjustment method for the gas cabinet further includes:

[0077] Step S501, obtaining a preset value range corresponding to the gas tank.

[0078] In this embodiment, a preset value range corresponding to the gas cabinet is obtained, wherein the preset value range four is determined according to the historical operating parameters of the gas cabinet.

[0079] Exemplarily, the preset numerical range may represent a parameter range for normal operation of the gas cabinet.

[0080] Step S502: during the operation of the gas holder, obtain the operation parameters of the gas holder.

[0081] During the operation of the gas holder, the operation parameters of the gas holder are obtained, wherein the operation parameters are parameters when the gas holder is in operation.

[0082] Exemplarily, a detection sensor is provided on the gas holder, and during the operation of the gas holder, the operation parameters of the gas holder are obtained through the detection sensor.

[0083] Step S503: When the operating parameter is not within the preset value range, the gas holder is controlled to stop operating.

[0084] When the operating parameters are not within the preset value range, it indicates that the gas tank is abnormal and the gas tank is controlled to stop operating.

[0085] Exemplarily, when the operating parameter is not within the preset value range, it can be confirmed that the gas tank has a fault, the gas tank needs to be stopped, and a fault warning is issued.

[0086] The flow adjustment method of the gas holder in this embodiment controls the gas holder to stop operating when the operating parameters of the gas holder are not within a preset value range, thereby ensuring the safety and stability of the gas holder.

[0087] In some embodiments, optionally, a flow adjustment method for a gas cabinet is proposed. After obtaining the operating parameters of the gas cabinet, the method further includes:

[0088] Step S601, storing the operating parameters to obtain a parameter database.

[0089] In this embodiment, the operating parameters of the gas holder are stored, and a parameter database of the gas holder is established, wherein the parameter database is a database for storing the operating parameters of the gas holder.

[0090] Exemplarily, the preset value range may be determined by data in the parameter database.

[0091] The flow adjustment method of the gas holder in this embodiment stores the operating parameters of the gas holder and establishes a parameter database of the gas holder, thereby ensuring the data integrity of the gas holder.

[0092] like Figure 2 As shown, in an embodiment of the present application, a flow regulating device 700 of a gas holder is provided. The gas holder is used to store the gas generated by a steelmaking furnace and transmit the gas to a gas demand end. The flow regulating device 700 of the gas holder includes:

[0093] An acquisition unit 702 is used to acquire the gas demand volume of the gas demand end and the first volume of the gas tank, and to acquire the working time interval of the steelmaking furnace;

[0094] The detection unit 704 is used to detect the volume of the gas when the steelmaking furnace delivers gas to the gas holder to obtain a first volume of the gas;

[0095] The control unit 706 is used to adjust the volume flow rate of gas delivered by the gas cabinet to the gas demand end according to the first capacity, the first volume, the gas demand volume and the time interval.

[0096] In this embodiment, the gas holder is used to store the gas generated by the steelmaking furnace and transmit the gas to the gas demand end, wherein the gas demand end is the gas consumption end. The steelmaking furnace will generate gas during the steelmaking process. The gas holder can collect and store the gas generated by the steelmaking furnace. The output end of the gas holder is connected to the gas demand end, and can transmit the gas to the gas demand end.

[0097] Exemplarily, the steelmaking furnace may be a converter for steelmaking.

[0098] The acquisition unit 702 acquires the gas demand volume of the gas demand end and the first volume of the gas tank, and acquires the time interval of the steelmaking furnace operation, wherein the gas demand volume is the volume of gas required by the gas demand end, the first volume is the rated volume of the gas tank, and the time interval is the time interval between multiple operations of the steelmaking furnace.

[0099] Illustratively, the first volume may be one thousand cubic meters.

[0100] Exemplarily, the gas demand volume may be five hundred cubic meters.

[0101] For example, the time interval may be a fixed one hour.

[0102] In the process of the steelmaking furnace generating gas and delivering the gas to the gas holder, the detection unit 704 detects the volume of the gas and determines a first volume of the gas, wherein the first volume is the volume of the gas generated by the steelmaking furnace.

[0103] Exemplarily, the main component of coal gas is carbon monoxide.

[0104] Exemplarily, a gas sensor is provided on the gas cabinet, and the volume of gas is detected by the gas sensor.

[0105] The control unit 706 is used to determine the volume flow rate corresponding to the gas based on the first capacity, the first volume, the gas demand volume and the time interval, and adjust the flow rate of gas delivered by the gas cabinet to the gas demand end according to the volume flow rate.

[0106] Among them, the volume flow rate is the volume flow rate of gas delivered by the gas tank to the gas demand end.

[0107] For example, when the gas demand volume is large and the first volume is small, the volume flow rate of gas delivered by the gasholder to the gas demand end can be reduced.

[0108] For example, when the gas demand volume is small and the first volume is large, the volume flow rate of gas delivered by the gasholder to the gas demand end can be increased.

[0109] Exemplarily, the volume flow rate of gas delivered by the gasholder to the gas demand end is adjusted so that the volume of gas stored in the gasholder is approximately half of the first volume, thereby ensuring the stability of the gasholder.

[0110] It should be noted that the volume flow rate of gas delivered by the gas tank to the gas demand end is determined based on multiple data such as the first capacity, the first volume, the gas demand volume and the time interval, thereby ensuring the accuracy of the volume flow rate data and further ensuring the accuracy of the volume flow rate regulation.

[0111] In addition, by accurately adjusting the volume flow of the gas, the efficiency of adjusting the gas flow can be improved, thereby reducing time costs.

[0112] For example, Figure 3 As shown, for the gas recovery system, it includes PLC (Programmable Logic Controller), gas tank and compressor. PLC can control the gas tank and compressor. On the basis of PLC, AI (Artificial Intelligence) module, database, control model and network communication module are added.

[0113] Exemplarily, the flow regulating device 700 of the gas cabinet can implement the following steps:

[0114] 1. Collect the data of gas cabinet capacity, cabinet position, cabinet speed, pressure and temperature, pressure and flow rate after the compressor through gas cabinet laser cabinet level meter, optical fiber cabinet level meter, pressure sensor, temperature sensor, flow meter and other instrument equipment, and transmit the data of gas cabinet and compressor operation to PLC, and PLC transmits the data to the control system database. The data mainly includes the gas generation volume, interval time and historical data of single furnace in steelmaking plant, the cabinet position and historical data of converter gas cabinet, the pressure, delivery volume and historical data after the compressor, and the usage volume and historical data of each converter user.

[0115] 2. The PLC compares the gas cabinet operation status data such as cabinet speed and cabinet temperature with the normal gas cabinet operation status values ​​to determine whether the gas cabinet is operating normally. The PLC transmits the signal to the AI ​​processing module. At the same time, it is also necessary to collect normal maintenance and abnormal fault information from steel mills and users, and transmit the data input that affects the operation of the gas cabinet and compressor to the AI ​​processing module.

[0116] 3. Automatically create a database of different control models through the AI ​​processing module, compare and analyze the operating data of the gas holder and compressor system with different types of gas holder control models, and automatically match the corresponding gas holder control method.

[0117] 4. The matched gas cabinet control method is transmitted to the computer screen of the manned operation room through network communication, and confirmed by the technical staff and the operator to finally determine the gas cabinet control method.

[0118] 5. After the operator selects the control method on the computer screen, it is sent to the PLC to control the gas cabinet and compressor related equipment and facilities to operate, and the operating data of the gas cabinet and compressor system after the operation is fed back to the PLC in a timely manner.

[0119] 6. The operating data of the gas cabinet and compressor system is transmitted to the control system database through PLC, providing a basis for the subsequent AI module to automatically create a control model.

[0120] The flow adjustment device 700 of the gas holder in this embodiment adjusts the volume flow of gas delivered by the gas holder to the gas demand end according to the first capacity, the first volume, the gas demand volume and the time interval, thereby ensuring the data accuracy of the volume flow of gas, and further ensuring the accuracy of the volume flow regulation, while improving the adjustment efficiency of the gas flow.
