It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0028] Figure 1 is a flow chart of a load regulation method for an air separation device according to an embodiment of the present invention. The method may include the following steps:

[0029] Step S101, determining the pressure of oxygen in the pipeline network at different time periods.

[0030] In the technical solution provided in the above step S101 of the present invention, the above pressure can be used to determine the relationship between the changing state and the fluctuating state of the pressure.

[0031] In this embodiment, the pressure of oxygen in the pipe network at different time periods is determined. Optionally, this embodiment measures the oxygen in the pipe network at different time periods by means of a pressure measuring device deployed at a pressure measuring point of the pipe network, and can obtain the pressure of oxygen in the pipe network at different time periods. The pressure measuring device may include at least one of the following devices: a pressure gauge and a pressure sensor, etc., which are only used as examples and are not specifically limited.

[0032] Step S102, in response to the pressure change state being a fluctuating state, determining at least one target air separation unit from the air separation units deployed in the pipeline network.

[0033] In the technical solution provided in the above step S102 of the present invention, the above-mentioned fluctuation state may include at least one of the following states: the pressure of oxygen in the pipeline network at different time periods fluctuates within a set range, and the pressure of oxygen in the pipeline network at different time periods exceeds the set range and undergoes a sudden change, which is only used as an example here and is not specifically limited.

[0034] In this embodiment, the above-mentioned state in which the pressure of oxygen in the pipeline network at different time periods exceeds the set range and a sudden change occurs may include: the pressure of oxygen in the pipeline network at different time periods exceeds the set range and a sudden decrease occurs, and the pressure of oxygen in the pipeline network at different time periods exceeds the set range and a sudden increase occurs. This is only an example for illustration and is not specifically limited.

[0035] In this embodiment, after determining the pressure of oxygen in the pipeline network at different time periods, in response to the change state of the pressure being a fluctuating state, at least one target air separation unit is determined from the air separation units deployed in the pipeline network. Optionally, this embodiment can determine the change state of the pressure based on determining the pressure of oxygen in the pipeline network at different time periods. The relationship between the change state of the pressure and the fluctuating state is judged to obtain a judgment result. If the obtained judgment result indicates that the change state of the pressure is a fluctuating state, at least one target air separation unit can be determined from the air separation units deployed in the pipeline network.

[0036] Step S103, determining the current load of the target air separation unit.

[0037] In the technical solution provided in step S103 of the present invention, the current load can be used to indicate the flow rate of oxygen delivered by the target air separation unit to the user and oxygen-consuming equipment in the current period. The oxygen-consuming equipment may be, but is not limited to, a gasifier and an oxygen compressor, etc., which are only used as examples and are not specifically limited.

[0038] In this embodiment, in response to the pressure change state being a fluctuating state, after determining at least one target air separation unit from the air separation units deployed in the pipe network, the current load of the target air separation unit is determined. Optionally, based on the determination of at least one target air separation unit, this embodiment uses a flow measurement device deployed at the oxygen delivery valve of the target air separation unit to measure the flow rate of oxygen delivered by the target air separation unit to users and oxygen-consuming equipment in the current period, and the current load of the target air separation unit can be obtained. Among them, the flow measurement device may include: vortex flowmeter, electromagnetic flowmeter, thermal flowmeter and ultrasonic flowmeter, etc., which are only used as examples here and are not specifically limited.

[0039] Step S104, adjusting the current load to the target load.

[0040] In the technical solution provided in step S104 of the present invention, the target load can be used to switch the changing state to the stable state. The target load can be used to indicate the flow rate of oxygen delivered by the target air separation unit to users and oxygen-consuming equipment in the future period.

[0041] In this embodiment, after determining the current load of the target air separation device, the current load is adjusted to the target load. Optionally, based on determining the current load of the target air separation device, according to the distance between each air separation device in the target air separation device and the pipeline network, the current load of each air separation device in the target air separation device is adjusted to the target load.

[0042] Optionally, in response to the pressure change state that the pressure exceeds the set range and suddenly drops, the distances between each air separation unit in the target air separation unit and the pipeline network are sorted, and the current load of each air separation unit in the target air separation unit is adjusted to the target load in order from far to near according to the sorted distances.

[0043] Optionally, in response to the pressure change state that the pressure exceeds a set range and suddenly rises, the distances between each air separation unit in the target air separation unit and the pipeline network are sorted, and the current load of each air separation unit in the target air separation unit is adjusted to the target load in order from near to far according to the sorted distances.

[0044] In the above steps S101 to S104 of the present application, when adjusting the load of the air separation unit, the pressure of oxygen in the pipeline network at different time periods can be determined. In response to the change state of the pressure being a fluctuating state, at least one target air separation unit can be determined from the air separation units deployed in the pipeline network, and then the current load of the target air separation unit can be determined, and the current load of the target air separation unit can be adjusted to the target load, thereby achieving the purpose of switching the change state of the target air separation unit to a stable state, thereby solving the technical problem of low efficiency of load regulation of the air separation unit, and further achieving the technical effect of improving the efficiency of load regulation of the air separation unit.

[0045] The above method of this embodiment is further introduced below.

[0046] As an optional implementation method, step S102, in response to the pressure change state being a fluctuating state, determines at least one target air separation unit from the air separation units deployed in the pipeline network, including: in response to the change state being a first fluctuating state, determines the working state of the backup oxygen system deployed in the pipeline network, and the switch state of the vent valve of each air separation unit in the air separation unit set; based on the working state and the switch state, determines at least one target air separation unit from the air separation unit set; in response to the change state being a second fluctuating state, determines the load of each air separation unit in the air separation unit set; based on the load, determines at least one target air separation unit from the air separation unit set; in response to the change state being a third fluctuating state, determines the opening of the vent valve of each air separation unit in the air separation unit set; based on the opening, determines at least one target air separation unit from the air separation unit set.

[0047] In this embodiment, the above-mentioned fluctuation state may include: a first fluctuation state, a second fluctuation state and a third fluctuation state.

[0048] In this embodiment, the first fluctuation state may be used to indicate that the pressure fluctuates within a set range. That is, the first fluctuation state may be that the pressure of oxygen in the pipeline network fluctuates within a set range at different time periods.

[0049] In this embodiment, the second fluctuation state can be used to indicate that the pressure does not fluctuate within the set range and the pressure is lower than the lower pressure limit. That is, the second fluctuation state can be that the pressure of oxygen in the pipeline network at different time periods exceeds the set range and suddenly decreases. It should be noted that the second fluctuation state can be caused by the start-up of the gasifier or the tripping of the air separation unit, which is only used as an example here and is not specifically limited.

[0050] In this embodiment, the third fluctuation state can be used to indicate that the pressure does not fluctuate within the set range and the pressure is higher than the upper pressure limit. That is, the third fluctuation state can be that the pressure of oxygen in the pipeline network at different time periods exceeds the set range and suddenly increases. It should be noted that the third fluctuation state can be caused by the gasifier tripping, which is only used as an example here and is not specifically limited.

[0051] In this embodiment, after determining the pressure of oxygen in the pipeline network at different time periods, in response to the change state being the first fluctuation state, the working state of the backup oxygen system deployed in the pipeline network and the switch state of the vent valve of each air separation unit in the air separation unit set are determined; based on the working state and the switch state, at least one target air separation unit is determined from the air separation unit set. Optionally, this embodiment can determine the change state of pressure on the basis of determining the pressure of oxygen in the pipeline network at different time periods. The relationship between the change state of pressure and the fluctuation state is judged to obtain a judgment result. If the obtained judgment result indicates that the change state of pressure is the first fluctuation state in the fluctuation state, the working state of the backup oxygen system deployed in the pipeline network can be determined according to the flow rate of oxygen delivered by the backup oxygen system to users and oxygen-consuming equipment in the current time period, and the switch state of the vent valve of each air separation unit in the air separation unit set can also be determined. According to the determined working state of the above-mentioned backup oxygen system and the switch state of the above-mentioned vent valve, at least one target air separation unit can be determined from the air separation unit set.

[0052] In this embodiment, after determining the pressure of oxygen in the pipeline network at different time periods, in response to the change state being the second fluctuation state, the load of each air separation unit in the air separation unit set is determined; based on the load, at least one target air separation unit is determined from the air separation unit set. Optionally, this embodiment can determine the change state of pressure on the basis of determining the pressure of oxygen in the pipeline network at different time periods. The relationship between the change state of pressure and the fluctuation state is judged to obtain a judgment result. If the obtained judgment result indicates that the change state of pressure is the second fluctuation state in the fluctuation state, the flow rate of oxygen delivered to users and oxygen-consuming equipment by each air separation unit in the air separation unit set in the current time period is measured by using the flow measurement equipment deployed at the oxygen delivery valve of each air separation unit in the air separation unit set, and the load of each air separation unit in the air separation unit set can be obtained. According to the load of each air separation unit in the above-mentioned air separation unit set, at least one target air separation unit can be determined from the air separation unit set.

[0053] In this embodiment, after determining the pressure of oxygen in the pipeline network at different time periods, in response to the change state being the third fluctuation state, the opening of the vent valve of each air separation unit in the air separation unit set is determined; based on the opening, at least one target air separation unit is determined from the air separation unit set. Optionally, this embodiment can determine the change state of pressure on the basis of determining the pressure of oxygen in the pipeline network at different time periods. The relationship between the change state of pressure and the fluctuation state is judged to obtain a judgment result. If the obtained judgment result indicates that the change state of pressure is the third fluctuation state in the fluctuation state, the opening of the vent valve of each air separation unit in the air separation unit set can be determined, and based on the determined opening of the vent valve of each air separation unit in the air separation unit set, at least one target air separation unit can be determined from the air separation unit set.

[0054] As an optional embodiment, at least one target air separation unit is determined from the air separation unit set based on the working state and the switch state, including: in response to the working state being the external delivery state and the switch state including the open state and the closed state, according to the distance between each air separation unit and the pipeline network and the oxygen supply of the backup oxygen system, at least one target air separation unit is determined from the air separation unit set; in response to the working state being the external delivery state and the switch state being the closed state, based on the load of each air separation unit, at least one target air separation unit is determined from the air separation unit set; in response to the working state being the cut-out state and the switch state including the open state and the closed state, based on the distance, at least one target air separation unit is determined from the air separation unit set; in response to the working state being the cut-out state and the switch state being the closed state, based on the target load in the load of each air separation unit, at least one target air separation unit is determined from the air separation unit set.

[0055] In this embodiment, the target load may include a first target load and a second target load, wherein the first target load may be greater than the loads other than the first target load in the target loads, and the second target load may be less than the loads other than the second target load in the target loads.

[0056] In this embodiment, the oxygen supply amount may be used to indicate the flow rate of oxygen delivered by the backup oxygen system to the user and the oxygen-consuming equipment in the current period.

[0057] In this embodiment, in response to the change state being the first fluctuation state, after determining the working state of the backup oxygen system deployed in the pipeline network and the switch state of the vent valves of each air separation unit in the air separation unit set, in response to the working state being the external delivery state, and the switch state including the open state and the closed state, at least one target air separation unit is determined from the air separation unit set according to the distance between each air separation unit and the pipeline network and the oxygen supply of the backup oxygen system. Optionally, this embodiment determines the relationship between the working state of the backup oxygen system and the external delivery state, and determines the relationship between the switch state and the open state and the closed state of the vent valves of each air separation unit in the air separation unit set based on the working state of the backup oxygen system and the switch state of the vent valves of each air separation unit in the air separation unit set. If it is determined that the working state of the backup oxygen system is the external delivery state, and the switch state of the vent valves of each air separation unit in the air separation unit set includes the open state and the closed state, then according to the distance between each air separation unit and the pipeline network, the vent valves of each air separation unit in the device are sequentially simulated to be closed alternately in a small amplitude, the oxygen pipeline network pressure is read, and the oxygen supply of the backup oxygen system is adjusted to 0, thereby determining the air separation units corresponding to the simulated closed vent valves from the air separation unit set as at least one target air separation unit.

[0058] In this embodiment, after determining the working state of the backup oxygen system deployed in the pipeline network and the switch state of the vent valve of each air separation unit in the air separation unit collection in response to the change state being the first fluctuation state, in response to the working state being the external delivery state and the switch state being the closed state, at least one target air separation unit is determined from the air separation unit collection based on the load of each air separation unit. Optionally, this embodiment determines the relationship between the working state of the backup oxygen system and the external delivery state on the basis of determining the working state of the backup oxygen system and the switch state of the vent valve of each air separation unit in the air separation unit collection, and determines the relationship between the switch state and the open state and the closed state of the vent valve of each air separation unit in the air separation unit collection. If it is determined that the working state of the backup oxygen system is the external delivery state and the switch state of the vent valve of each air separation unit in the air separation unit collection is the closed state, the flow rate of oxygen delivered to users and oxygen-consuming equipment by each air separation unit in the air separation unit collection in the current period is measured by using the flow measurement device deployed at the oxygen delivery valve of each air separation unit in the air separation unit collection, so as to obtain the load of each air separation unit in the air separation unit collection. The load of each air separation unit measured is sequentially simulated to be increased, the oxygen network pressure is read, and the output of the backup oxygen system is reduced until the output of the backup oxygen system is zero, thereby centralizing the air separation units and determining the air separation units corresponding to each of the simulated increased loads as at least one target air separation unit.

[0059] In this embodiment, in response to the change state being a first fluctuation state, after determining the working state of the backup oxygen system deployed in the pipeline network and the switch state of the vent valves of each air separation unit in the air separation unit set, in response to the working state being a cut-out state, and the switch state including an open state and a closed state, at least one target air separation unit is determined from the air separation unit set based on the distance. Optionally, this embodiment determines the relationship between the working state of the backup oxygen system and the cut-out state, and determines the relationship between the switch state and the open state and the closed state of the vent valves of each air separation unit in the air separation unit set based on the working state of the backup oxygen system and the switch state of the vent valves of each air separation unit in the air separation unit set. If it is determined that the working state of the backup oxygen system is the cut-out state, and the switch state of the vent valves of each air separation unit in the air separation unit set includes the open state and the closed state, then according to the distance between each air separation unit and the pipeline network, the vent valves of each air separation unit are sequentially simulated to be closed, the oxygen pipeline network pressure is read, and the load of each air separation unit is reduced until the vent valves are all closed, thereby determining the air separation units corresponding to the simulated closed vent valves from the air separation unit set as at least one target air separation unit.

[0060] In this embodiment, in response to the change state being a first fluctuation state, after determining the working state of the backup oxygen system deployed in the pipeline network and the switch state of the vent valves of each air separation unit in the air separation unit set, in response to the working state being a cut-out state and the switch state being a closed state, based on the target load in the load of each air separation unit, at least one target air separation unit is determined from the air separation unit set. Optionally, this embodiment judges the relationship between the working state and the cut-out state of the backup oxygen system on the basis of determining the working state of the backup oxygen system and the switching state of the vent valves of each air separation unit in the air separation unit set, and measures the flow rate of oxygen delivered to users and oxygen-consuming equipment by each air separation unit in the air separation unit set in the current time period, so as to obtain the load of each air separation unit in the air separation unit set, take the maximum load in the load as the first target load, and take the minimum load in the load as the second target load, thereby simulating the reduction of the first target load in the target load and simulating the increase of the second target load, thereby determining the air separation units corresponding to the simulated reduction of the first target load and the simulated increase of the second target load, respectively, from the air separation unit set as at least one target air separation unit.

[0061] As an optional implementation method, based on the load, at least one target air separation unit is determined from the air separation unit set, including: determining a target load below a load threshold from the load; and determining, from the air separation unit set, air separation units other than the air separation unit corresponding to the target load as at least one target air separation unit.

[0062] In this embodiment, the load threshold can be used to determine whether the air separation unit has tripped. For example, the load threshold can be 70%. If the load of the air separation unit is less than 70%, it means that the air separation unit has tripped. The value of the threshold is only used as an example and is not specifically limited.

[0063] In this embodiment, in response to the change state being the second fluctuation state, after determining the load of each air separation unit in the air separation unit set, a target load below the load threshold is determined from the loads. Optionally, this embodiment compares the load of each air separation unit with the load threshold on the basis of determining the load of each air separation unit in the air separation unit set, and uses the load below the load threshold as the target load.

[0064] In this embodiment, after determining the target load below the load threshold from the load, the air separation units other than the air separation units corresponding to the target load are determined as at least one target air separation unit from the air separation unit set. Optionally, based on determining the target load below the load threshold, if the number of air separation units corresponding to the target load is 5, the air separation units other than the 5 air separation units corresponding to the target load are determined as at least one target air separation unit from the air separation unit set, and the number is only for illustration and is not specifically limited.

[0065] As an optional embodiment, at least one target air separation unit is determined from the air separation unit set based on the opening, including: determining the target opening from the opening; and determining the air separation unit corresponding to the target opening as at least one target air separation unit from the air separation unit set.

[0066] In this embodiment, the above-mentioned target opening degree may be smaller than the opening degrees other than the target opening degree among the opening degrees.

[0067] In this embodiment, in response to the change state being the third fluctuation state, after determining the opening of the vent valve of each air separation device in the air separation device collection, the target opening is determined from the openings. Optionally, this embodiment, on the basis of determining the opening of the vent valve of each air separation device in the air separation device collection, sorts the openings of the vent valves of each air separation device, selects the minimum opening from the sorted openings, and determines the selected minimum opening as the target opening.

[0068] In this embodiment, after determining the target opening from the opening, the air separation device corresponding to the target opening is determined as at least one target air separation device from the air separation device set. Optionally, based on the determination of the target opening, if the number of air separation devices corresponding to the target opening is 6, the 6 air separation devices corresponding to the target opening are determined as at least one target air separation device from the air separation device set. The number is only for example and is not specifically limited.

[0070] In this embodiment, the at least one target air separation device may include a first target air separation device and a second target air separation device, wherein the distance between the first target air separation device and the pipeline network may be greater than the distance between the second target air separation device and the pipeline network.

[0071] In this embodiment, after determining the current load of the target air separation unit, the current load of the first target air separation unit and the current load of the second target air separation unit are determined. Optionally, this embodiment uses a flow measurement device deployed at the oxygen delivery valve of the first target air separation unit to measure the flow rate of oxygen delivered by the first target air separation unit to users and oxygen-consuming equipment in the current period, so as to obtain the current load of the first target air separation unit, and uses a flow measurement device deployed at the oxygen delivery valve of the second target air separation unit to measure the flow rate of oxygen delivered by the second target air separation unit to users and oxygen-consuming equipment in the current period, so as to obtain the current load of the second target air separation unit.

[0072] In this embodiment, after determining the current load of the first target air separation device and the current load of the second target air separation device, the current load of the second target air separation device is adjusted to the target load after adjusting the current load of the first target air separation device to the target load, under the condition that the air separation devices other than the air separation device corresponding to the target load are determined as at least one target air separation device from the air separation device set.

[0073] In this embodiment, after determining the current load of the first target air separation device and the current load of the second target air separation device, the current load of the first target air separation device is adjusted to the target load after adjusting the current load of the second target air separation device to the target load under the condition that the air separation device corresponding to the target opening is determined as at least one target air separation device from the air separation device set.

[0074] In the embodiment of the present invention, when adjusting the load of the air separation unit, the pressure of oxygen in the pipeline network at different time periods can be determined. In response to the change state of the pressure being a fluctuating state, at least one target air separation unit can be determined from the air separation units deployed in the pipeline network, and then the current load of the target air separation unit is determined, and the current load of the target air separation unit is adjusted to the target load, thereby achieving the purpose of switching the change state of the target air separation unit to a stable state, thereby solving the technical problem of low efficiency of load regulation of the air separation unit, and further achieving the technical effect of improving the efficiency of load regulation of the air separation unit.

[0075] The technical solution of the embodiment of the present invention is illustrated below in conjunction with preferred implementation modes.

[0076] In the process of building large-scale coal chemical projects, the load regulation of air separation units generally refers to the automatic load change of a single air separation unit. The above-mentioned air separation units are mostly supporting air separation units in the metallurgical industry. After the load number of the air separation unit is manually input into the operating system, it is necessary to adjust the set parameters after computer calculation, which leads to the technical problem of low efficiency of load regulation of the air separation unit.

[0077] In order to solve the above technical problems, an embodiment of the present invention proposes a load regulation method for an air separation unit. When adjusting the load of the air separation unit, the pressure of oxygen in the pipeline network at different time periods can be determined. In response to the change state of the pressure being a fluctuating state, at least one target air separation unit can be determined from the air separation units deployed in the pipeline network, and then the current load of the target air separation unit can be determined, and the current load of the target air separation unit can be adjusted to the target load, thereby achieving the purpose of switching the change state of the pressure to a stable state, thereby solving the technical problem of low efficiency of load regulation of the air separation unit, and further achieving the technical effect of improving the efficiency of load regulation of the air separation unit.

[0078] In this embodiment, the pipe network may be an oxygen pipe network. For example, FIG2(a) is a schematic diagram of an oxygen pipe network according to an embodiment of the present invention. As shown in FIG2(a), in the oxygen pipe network, point P is a pressure measurement point of the oxygen pipe network. Among them, the air separation unit 2011 and the air separation unit 2012 can respectively deliver oxygen to users 2021 to users 2023 and gasifiers 2031 to gasifiers 203n through their respective oxygen delivery valves; the air separation unit 2011 and the air separation unit 2012 can discharge oxygen to the external environment through their respective oxygen vent valves; the backup oxygen production system 204 can also deliver oxygen to users 2021 to users 2023 and gasifiers 2031 to gasifiers 203n through the oxygen delivery valve; users 2021 to users 2023 and gasifiers 2031 to gasifiers 203n can receive oxygen delivered from the air separation unit 2011, the air separation unit 2012 and the backup oxygen production system 204 through their respective oxygen intake valves.

[0079] In this embodiment, the current load of the target air separation unit can be adjusted to the target load through the pressure regulation method of the pipeline network, thereby achieving the purpose of switching the pressure change state to a stable state. The pressure regulation method of the pipeline network can be shown in Figure 2 (b), which is a flow chart of a pressure regulation method of a pipeline network according to an embodiment of the present invention. The method may include the following steps:

[0080] Step S211, detecting the pressure of the oxygen pipe network.

[0081] In the technical solution provided in the above step S211 of the present invention, after the oxygen pipeline network enters normal operation, the pressure fluctuation may be as follows:

[0082] Case 1: The oxygen network pressure fluctuates within the set range;

[0083] Case 2: The oxygen network pressure suddenly drops (for example, when the gasifier is started or the air separation unit is tripped);

[0084] Case three: The oxygen network pressure suddenly increases (for example, the gasifier trips).

[0085] In this embodiment, a first calculator is provided, and the input values ​​of the first calculator may include the following: the rate of change of the pipe network pressure and the oxygen flow rate of each air separation unit, the maximum output oxygen flow rate set by each air separation unit (this value is the initial setting value, used to protect the device), the coefficient of the oxygen delivery pipe of each air separation unit being incorporated into the pipe network interface (this value is the initial setting value, because the gas is easy to compress, there is a rush to increase the volume under the same circumstances, and the purpose of setting this coefficient is to make the synchronous regulation of multiple air separation units not limited by the distance connected to the oxygen pipe network), and the output is the vent valve adjustment signal of each air separation pipe network, the load of each air separation unit (also known as the delivery flow, the delivery flow can be achieved by changing the frequency of the oxygen pump), the output value of the backup oxygen system, and the oxygen input of the gasifier. After the pressure signal of the oxygen pipe network is sent to the first calculator, the first calculator compares the pressure value represented by the pressure signal with the set range of the pipe network pressure. If it is determined that the pressure fluctuates within the set range, it will read in turn whether the backup oxygen system has an external delivery signal, whether the vent valve of each air separation unit is fully closed, and whether the load of each air separation unit is the same. In order to reduce the number of adjustments, it can be set that no adjustment will be made if the load difference is within 2%.

[0086] In this embodiment, for situation 1:

[0087] First, if it is detected that the backup oxygen system is in the external delivery state, and the switch state of the vent valve of the air separation unit includes an open state and a closed state, then the vent valve of the device is closed alternately in small amplitudes, the oxygen network pressure is read, and the delivery volume of the backup oxygen system is closed, wherein the network pressure is within the set value as the criterion during the adjustment process. If the switch state of the vent valve is closed, and the backup oxygen system is still in the external delivery state, then the device load is increased in turn, the oxygen network pressure is read, and the output of the backup oxygen system is reduced until the output of the backup oxygen system is zero. If the backup oxygen system is in the cut-out state, and the switch state of the vent valve of the air separation unit includes an open state and a closed state, then the vent valve is closed in turn, the oxygen network pressure is read, and the load of each device is reduced until the vent valve is completely closed.

[0088] Second, if it is detected that the backup oxygen system is in the external delivery state and the switch state of the vent valve of the air separation unit is closed, the load of the air separation unit is increased in sequence, the oxygen pipeline pressure is read, and the output of the backup oxygen system is reduced until the output of the backup oxygen system is zero.

[0089] Third, if it is detected that the backup oxygen system is in the cut-out state, and the switch state of the vent valve of the air separation unit includes the open state and the closed state, the vent valves are closed in sequence, the oxygen pipeline pressure is read, and the load of each air separation unit is reduced until all the vent valves are closed.

[0090] Fourth, if it is detected that the backup oxygen system is in the cut-out state and the switch state of the vent valve of the air separation unit is in the closed state, the load of each air separation unit is read, and the load of the highest air separation unit and the load of the lowest air separation unit in the cluster are selected, and the load of the lowest air separation unit is increased in turn, the pipeline pressure is read, the load of each air separation unit is read, and the load of the highest air separation unit is lowered until the difference between the two loads is within the set value (for example, the set value can be an initialization set value, which can be adaptively adjusted with reference to the number of air separation units in the cluster and the adjustment sensitivity).

[0091] In this embodiment, for situation 2, if the air separation unit suddenly trips, or the back system user (mostly the gasifier) ​​suddenly increases the load, or there is an air separation unit tripping, the oxygen pipe network pressure will drop sharply synchronously, and the first calculator will detect that the pressure of the pipe network exceeds the lower limit, that is, the pipe network changes from being stable in the early stage to exceeding the lower limit. When the first calculator detects that the pressure of the pipe network exceeds the lower limit, the load of each air separation unit is read (if the load of an air separation unit is less than 70%, the system will alarm at the same time, prompting the corresponding air separation unit to trip), select the air separation unit with the lowest load, alternately increase the load of the air separation unit in sequence (that is, increase the speed of the external oxygen pump), read the pressure of the pipe network, and judge the air separation unit with the smallest load in the cluster (if the load is less than 70%, that is, tripping, then it is not selected). If the pressure of the pipe network reaches the set range, it will enter situation 1. If each air separation unit in the cluster has reached full load, but the pressure of the pipe network is still lower than the lower limit, the backup oxygen system is started, the external delivery volume of the backup oxygen system is alternately increased, and the pipe network pressure is read until the pipe network pressure reaches the set range.

[0092] It should be noted that if there are two or more air separation units with the same load, the load of the air separation unit at the end (that is, the air separation unit farthest from the pressure detection point of the pipeline network) will be adjusted first. The priority has been set according to the length of the pipeline between the delivery valve of each air separation unit and the pressure measurement point of the oxygen pipeline network. The longer the length, the higher the priority of the corresponding air separation unit.

[0093] In this embodiment, for situation three, if the gasifier suddenly trips or the user of the rear system suddenly quits gas, the pressure of the oxygen pipe network will rise synchronously, and the first calculator will detect that the pressure of the pipe network exceeds the upper limit, that is, the pressure of the pipe network changes from being stable within the set range in the early stage to exceeding the upper limit. When the first calculator detects that the pressure of the oxygen pipe network exceeds the upper limit, it detects the opening of the vent valve of each air separation unit, selects the air separation unit with the smallest opening of the vent valve, alternately opens the opening of the external valve of the air separation unit in small amplitudes, and reads the pressure of the pipe network until the pressure of the pipe network reaches the set range.

[0094] It should be noted that, under normal circumstances, the vent valves of each air separation unit are all closed, that is, the opening of the vent valves of each air separation unit is zero. Therefore, the priority is set in advance, that is, when the opening of the vent valves of each air separation unit is the same, the priority has been set according to the pipeline length of the delivery valve of each air separation unit and the pressure measuring point of the oxygen pipeline network. If the length is shorter, the corresponding air separation unit has a higher priority, that is, the vent valve of the air separation unit is opened first under the same conditions.

[0095] After the pressure of the oxygen pipe network is detected, the process proceeds to step S212 to determine whether the pressure of the oxygen pipe network exceeds the pressure range.

[0096] If the pressure of the oxygen pipeline network exceeds the pressure range, the process proceeds to step S213, where the vent valve of the device with the largest external delivery volume is opened, and gradually opened larger (1% each time) according to the pipeline network pressure until it is fully opened.

[0097] In the technical solution provided in step S213 of the present invention, if there are two or more air separation units with the same maximum delivery volume, the air separation unit closest to the pressure measurement point is selected, and the vent valve of the air separation unit is gradually opened. When two or more air separation units are fully opened or one air separation unit is fully opened for 5 minutes, a manual processing prompt is displayed.

[0098] If the pressure of the oxygen network does not exceed the pressure range, the process proceeds to step S214 to adjust the load of each air separation unit until each air separation unit reaches full load. If the pressure of the oxygen network still does not meet the standard, the backup oxygen production system is started.

[0099] After starting the backup oxygen production system, proceed to step S215, step S216 and step S217 to detect whether the vent valve of each air separation unit has output, detect whether the vent valve of the backup oxygen production system has output, and detect whether the load of each air separation unit is at the average load.

[0100] If the vent valve of each air separation unit has no output, the process ends. If the vent valve of each air separation unit has output, enter step S218, gradually close the vent valve of each air separation unit according to the opening of 1% until it is fully closed; if the vent valve of the backup oxygen production system has no output, the process ends. If the vent valve of the backup oxygen production system has output, enter step S219, gradually close the vent valve of the backup oxygen production system according to the opening of 1% until the backup oxygen production system is cut out; if the vent valve of the backup oxygen production system has no output, the process ends. If the load of each air separation unit is above the average load, the process ends; if the load of each air separation unit is not above the average load, enter step S220, adjust the load of each air separation unit in turn until the load of each air separation unit is above the average load.

[0101] In this embodiment, the load regulation method of the air separation unit in the present application is applied to a single air separation unit, and a load regulation method of the single air separation unit can be obtained. The load regulation method of the single air separation unit can be shown in FIG2(c), which is a flow chart of a load regulation method of a single air separation unit according to an embodiment of the present invention. The method may include the following steps:

[0102] Step S231: The first calculator sends a signal for adjusting the frequency of the external oxygen pump to the second calculator.

[0103] In the technical solution provided in the above step S231 of the present invention, considering that the product delivered by the device is gas (easy to compress, greatly affected by the pressure of the pipeline network), when extreme conditions occur (for example, when the pressure of the pipeline network drops sharply, the delivered oxygen will overflow rapidly, and the delivered amount is much higher than the maximum load, resulting in an extreme imbalance of the distillation system, and the air separation unit will jump), the oxygen pump is set to a maximum frequency, which depends on the oxygen pump and the motor, and requires that the oxygen delivery amount of the oxygen pump at this frequency is ≤ the maximum load of the device (for example, 105%). Limited by the surge of the unit, the load of the general air separation unit can be adjusted within the range of 75% to 105%.

[0104] After sending a signal for adjusting the frequency of the external oxygen pump to the second calculator, the process proceeds to step S232 to determine whether the current frequency of the oxygen pump is greater than the set frequency.

[0105] If the current oxygen pump frequency is greater than the set frequency, the process returns to step S231. If the current oxygen pump frequency is less than the set frequency, the process proceeds to step S233 to adjust the frequency of the external oxygen pump to increase the flow rate of oxygen delivery.

[0106] In the technical solution provided in the above step S233 of the present invention, by increasing the gas expander to adjust the expansion amount, increasing the guide vane opening of the booster, and increasing the guide vane opening of the air compressor, the frequency of the external oxygen pump can be adjusted to increase the flow rate of the delivered oxygen.

[0107] In this embodiment, after increasing the gas expander adjustment expansion amount, the circulating water volume of the expander booster cooler, the distillation volume of the distillation system, and the tower liquid level are changed in sequence. After increasing the opening of the booster guide vane, the circulating water flow of the cooler, the corresponding valve of the distillation system, etc. are adjusted. After increasing the opening of the air compressor guide vane, the precooling system pump frequency, ice machine load, and circulating water volume are adjusted.

[0108] In this embodiment, when adjusting the load of the air separation unit, the pressure of oxygen in the pipeline network at different time periods can be determined. In response to the change state of the pressure being a fluctuating state, at least one target air separation unit can be determined from the air separation units deployed in the pipeline network, and then the current load of the target air separation unit can be determined, and the current load of the target air separation unit can be adjusted to the target load, thereby achieving the purpose of switching the change state of the pressure to a stable state, thereby solving the technical problem of low efficiency of load regulation of the air separation unit, and further achieving the technical effect of improving the efficiency of load regulation of the air separation unit.
