[0023] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0024] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0025] According to an embodiment of the present application, an embodiment of a method for controlling the working state of a gasifier is provided. 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.

[0026] In this embodiment, a method for controlling the working state of a gasifier is proposed. When a fault occurs in the coal chemical industry chain, the method can determine the type of fault, call the corresponding emergency response standard based on the fault type, determine the emergency response strategy corresponding to the fault according to the emergency response standard, and control the working state of the gasifier according to the emergency response strategy, thereby solving the technical problem of low efficiency in controlling the gasifier and achieving the technical effect of improving the efficiency of controlling the gasifier.

[0027] Figure 1 FIG. 1 is a flow chart of a method for controlling the working state of a gasifier according to an embodiment of the present application. Figure 1 As shown, the method may include the following steps:

[0028] Step S102, in response to a fault in the coal chemical industry chain, determining the fault type of the fault, wherein the coal chemical industry chain includes at least one gasifier.

[0029] In the technical solution provided in the above step S102 of the present application, the above coal chemical industry chain may include an upstream device, a downstream device and at least one gasifier (or a clustered gasifier), which can be used to process coal. The above upstream device can be used to pre-treat the raw coal, for example, it can be used to crush, dry, grind and other processes of the raw coal, and may include a device for pre-treating the raw coal, for example, it may include an air separation device. The above downstream device can be used to further process, convert or refine the pre-treated raw coal, and may include a device for further processing, converting or refining the raw coal, for example, it may include a purification device, a conversion device, a synthesis device and an oil product processing device.

[0030] Optionally, if there is a fault in the coal chemical industry chain, the fault type of the fault can be determined. The fault type may include an air separation unit fault, a purification unit fuel gas compressor fault, a carbon dioxide compressor fault, etc., which can be used to determine the faulty device in the coal chemical industry chain. The above-mentioned fault may be a production safety accident in the coal chemical industry chain.

[0031] It should be noted that this is only an example, and there is no specific restriction on the content included in the coal chemical industry chain, the type of upstream equipment, the type of downstream equipment, and the type of failure.

[0032] Step S104, acquiring an emergency handling standard associated with the fault type, wherein the emergency handling standard is used to guide the switching of the working state of the gasifier.

[0033] In the technical solution provided in the above step S104 of the present application, the above emergency handling standard can be a gasifier determination standard, which can include a parking priority determination standard and a switching priority determination standard, which can be used to guide the switching of the working state of the gasifier. The above parking priority determination standard can be a shutdown priority, which can be a gasifier optimal operation scoring standard.

[0034] Optionally, a shutdown priority may be established according to emergency response standards to shut down gasifiers with short operating cycles and high operating quality, thereby ensuring that the gasifiers can be restarted normally.

[0035] Optionally, different fault types correspond to different emergency response standards. Therefore, after determining the fault type, the emergency response strategy corresponding to the fault can be quickly determined based on the emergency response standard corresponding to the fault type, thereby achieving the purpose of improving the efficiency of determining the emergency response strategy.

[0036] Optionally, the above parking priority judgment standard may refer to a set of rules for automatically and selectively deactivating some gasifiers according to the operating status and performance of the gasifier in an emergency situation such as a failure of an upstream or downstream device in the coal chemical industry chain leading to insufficient supply of key media. By using the parking priority judgment standard, secondary accidents caused by the shutdown of a single or multiple gasifiers can be avoided, thereby ensuring the safe and stable operation of the entire gasification device and even the coal chemical industry chain. For example, the parking priority judgment standard can be a standard for judging the operating cycle, that is, a gasifier with a short operating cycle means that it has completed maintenance and overhaul in the near future and has faster restart conditions. Therefore, when emergency shutdown is required, priority can be given to deactivating a gasifier with a short operating cycle to reduce the time cost of subsequent resumption of production. Or it can be an operating quality scoring standard, which includes but is not limited to indicators such as the operating load of the gasifier, the stability of key operating parameters, energy efficiency, and environmental emissions. When encountering a situation where some gasifiers need to be stopped, the standard can be used to give priority to deactivating gasifiers with higher operating quality scores to ensure that in an emergency, high production efficiency and product quality can still be maintained.

[0037] Optionally, the above-mentioned switching priority judgment criteria can be used to automatically prioritize and switch the source or type of medium that the gasifier relies on when the supply of common medium (e.g., fuel gas, oxygen, carbon dioxide, high-pressure nitrogen, etc.) becomes unstable or insufficient, to ensure that the gasifier can still operate safely under limited medium conditions.

[0038] Optionally, through the formulation and application of the above standards, the gasification equipment in the coal chemical industry chain can achieve rapid response and safe disposal through intelligent decision-making and control when encountering various emergency situations, thereby improving the operating efficiency and safety of the entire industry chain.

[0039] Step S106, determining an emergency response strategy corresponding to the fault according to the emergency response standard, wherein the emergency response strategy is used to represent a control rule that puts the gasifier in a safe state.

[0040] In the technical solution provided in the above step S106 of the present application, the above emergency response strategy can be used to determine the shutdown time of the gasifier, the number of gasifiers to be shut down, etc., and can be used to represent the control rules that put the gasifier in a safe state. This is only for example, and there is no specific restriction on the determination of the emergency response strategy.

[0041] Optionally, an emergency response strategy may be determined according to the interlocking procedure and the gasifier shutdown priority to automatically select the gasifier for shutdown.

[0042] Optionally, this embodiment ensures that the gasifier can quickly and safely enter a protection state when encountering different types of faults based on preset judgment standards (ie, emergency handling signs) and interlocking procedures, thereby avoiding or reducing the impact of the accident.

[0043] For example, if the fault type is insufficient oxygen supply to the air separation unit, according to the load rate of the air separation unit, some gasifiers can be automatically selected for shutdown according to the pre-set gasifier shutdown priority judgment standard, and the supply of important media in the system can be adjusted to ensure the safety and efficiency of the remaining gasifiers. For example, assuming that the load rate of the air separation unit drops to 80%, the emergency response strategy can be to automatically shut down two gasifiers with short operating cycles and high operating quality. At the same time, the interlocking program can automatically adjust the oxygen pipeline pressure to ensure that the oxygen supply of the remaining gasifiers can still meet the minimum safe operation requirements. The implementation of this emergency response strategy can avoid the interlocking jump of the gasifier due to insufficient oxygen supply, reduce the risk of large-scale shutdown, and ensure the overall stable operation of the gasification unit.

[0044] For another example, when a fuel gas (FG) compressor fails and causes the fuel gas supply pressure to drop to the interlock value, it can be determined that the fault type is a fuel gas compressor failure. The system can automatically switch the fuel gas source of the ignition burner with a short running time and no leakage to liquefied petroleum gas (LPG) based on the judgment indicators such as the running time of the ignition burner and the return flow rate difference of the cooling water, and at the same time switch the burner support purge gas to high-pressure nitrogen (N2). Optionally, in the case of a fuel gas compressor failure, if the fuel gas load rate drops to 90%, according to the emergency disposal strategy, each gasifier area can automatically select a gasifier with a short running time and a return flow rate difference of 0 on the cooling water, and cut its ignition burner fuel gas (FG) to liquefied petroleum gas (LPG), and at the same time automatically switch the burner support purge gas from FG to high-pressure nitrogen (N2). This measure can prevent interlock shutdown caused by insufficient fuel gas supply, reduce production interruptions, and improve the efficiency and accuracy of emergency disposal.

[0045] As an optional example, when the failure of the carbon dioxide compressor causes insufficient carbon dioxide supply to the gasifier, it can be determined that the fault type at this time is a carbon dioxide compressor failure, and the emergency disposal standard can be determined to select a gasifier with lower heat loss, switch the carbon dioxide supply to high-pressure nitrogen, and adjust the gasifier load. Further, according to the emergency disposal standard, the emergency disposal strategy can be determined as follows: according to the main heat loss and slag heat loss of the gasifier, automatically select the gasifier with lower heat loss, switch the carbon dioxide supply to high-pressure nitrogen, and adjust the gasifier load to maximize the operation stability of the entire gasification system. Optionally, if the carbon dioxide load rate drops to 80%, according to the emergency disposal strategy, the system can automatically select a gasifier with lower main heat loss and slag heat loss in each area, switch carbon dioxide (CO2) to high-pressure nitrogen (NH), and reduce the gasifier load to 75% to reduce the use of high-pressure nitrogen, so as to ensure that the entire system can still operate safely when the carbon dioxide supply is insufficient.

[0046] Optionally, emergency response strategies can be determined through pre-set judgment criteria and interlocking procedures. The combination of automated control and artificial intelligence systems enables intelligent fault response and handles faults according to emergency response strategies. This method can not only quickly identify and isolate the source of the fault, but also maximize the safe and stable operation of the gasifier and reduce production losses and accident risks by optimizing medium supply and adjusting load strategies under limited resources.

[0047] Optionally, the above emergency response strategy may be pre-set based on testing and experience, and may be used to determine the emergency response required for the coal chemical industry chain under the current fault type.

[0048] Step S108, controlling the working state of the gasifier to a safe state according to the emergency handling strategy.

[0049] In the technical solution provided in the above step S108 of the present application, according to the emergency disposal strategy, the working state of at least one gasifier in the clustered gasifier can be controlled, so as to ensure that the coal chemical industry chain is in a safe state. The above working state may include an open or closed state.

[0050] Optionally, the gasifier is used to implement dry pulverized coal gasification technology and can be used to convert coal.

[0051] At present, promoting the development of modern coal chemical industry has significant economic and social benefits. Coal chemical projects are also key projects to promote the clean, safe and efficient use of coal and achieve green and low-carbon transformation. The achievements of coal chemical industry have been vigorously promoted and applied. Therefore, the clustering of gasification units in coal chemical projects is an inevitable development trend.

[0052] Alternatively, due to efficient material supply, material and energy integration, and scale benefits, unnecessary intermediate links and resource waste can be resolved, and more effective coupling can be formed into a new systematic functional combination. Projects with more than 10 gasifiers can be classified as cluster engineering projects. While improving the automatic control system, stability, and anti-interference capabilities of each system, such clustered gasifiers must also consider how to safely, efficiently, and quickly handle emergency situations when production failures occur in each system of the entire device, so as to avoid production safety accidents such as coordination errors, misoperation, and improper handling.

[0053] Whenever a large-scale system production and operation failure occurs in the coal chemical industry chain, the dispatcher usually coordinates and directs each unit to deal with the emergency. However, there are differences in the operating conditions of the gasification furnace. When the furnace needs to be shut down, the above method cannot accurately issue instructions, which delays time and easily causes secondary accidents.

[0054] In the existing dry pulverized coal gasification technology, each gasifier and public system has only a single device protection interlock, and there is a lack of interlock protection system between the gasification device and the upstream and downstream devices such as air separation, purification, synthesis, and oil products. The dry pulverized coal gasification technology lacks an artificial intelligence system and is not coupled with the system big data and artificial intelligence. Therefore, there is a technical problem of low efficiency in controlling the gasifier.

[0055] To solve the above problems, in this embodiment, a clustered gasifier interlocking protection system is established. When the upstream and downstream devices fail to operate, the clustered gasifier interlocking protection system can determine the emergency response strategy based on the emergency response standards associated with the fault type, and automatically determine and choose to shut down the gasifier according to the emergency response strategy, thereby achieving automatic intervention, adjusting the pressure of important medium pipelines, and ensuring the overall smooth operation of the device.

[0056] Optionally, the cluster gasifier interlocking protection system can be an artificial intelligence system, which can be used to couple coal chemical gasification equipment, operation big data and artificial intelligence to achieve human-machine integration. Effectively utilize digital technology to ensure the high-quality and safe development of coal chemical projects.

[0057] In this embodiment, the above-mentioned clustered gasifier interlocking protection system may include a clustered gasifier interlocking protection program. By setting up a clustered gasifier interlocking protection program, the program can be shielded and put into use, and is uniformly arranged by the dispatcher. When the upstream and downstream devices of the coal chemical industry chain (which can be referred to as coal chemical industry) fail, the public pipeline medium is insufficient, and emergency operations such as gasifier shutdown are required, the emergency response strategy can be determined according to the interlocking program and the gasifier shutdown priority standard (that is, the emergency response standard) to automatically select the gasifier to be shut down. The clustered gasifier interlocking system can be uniformly managed by the dispatcher, which is different from the interlocking system of each device and exists independently, thereby solving the technical problem of low efficiency in gasifier control and achieving the technical effect of improving the low efficiency in gasifier control.

[0058] Through the above steps S102 and S108 of the present application, in response to the existence of a fault in the coal chemical industry chain, the fault type of the fault is determined; the emergency handling standard associated with the fault type; according to the emergency handling standard, the emergency handling strategy corresponding to the fault is determined, wherein the emergency handling strategy is used to represent the control rules that put the gasifier in a safe state; according to the emergency handling strategy, the working state of the gasifier is controlled to be a safe state. That is to say, in the embodiment of the present application, when there is a fault in the coal chemical industry chain, the fault type can be determined, the corresponding emergency handling standard can be called based on the fault type, according to the emergency handling standard, the emergency handling strategy corresponding to the fault is determined, and the working state of the gasifier is controlled according to the emergency handling strategy, thereby solving the technical problem of low efficiency of gasifier control and achieving the technical effect of improving the low efficiency of gasifier control.

[0059] The above method of this embodiment is further introduced below.

[0060] As an optional implementation, step S102, in response to a fault in the coal chemical industry chain, determines the fault type of the fault, including: in response to the fault in the coal chemical industry chain, determines the target device where the fault occurs in the coal chemical industry chain; based on the target device, determines the fault type, wherein the target device is used to exchange materials with a gasifier.

[0061] In this embodiment, the target device may be a downstream device or an upstream device. It may be used to exchange materials with the gasifier. The materials may be oxygen, nitrogen, steam, etc., which are not specifically limited here.

[0062] Optionally, if there is a fault in the coal chemical industry chain, the target device with the fault can be determined, and the fault type matching the target device can be determined. For example, if the target device with the fault is an air separation unit, the fault type can be determined to be an air separation unit fault. If the target device with the fault is a fuel gas compressor, the fault type can be determined to be a fuel gas compressor fault. No specific restrictions are made here.

[0063] As an optional implementation, based on the target equipment, the fault type is determined, including: in response to the target equipment being a space separation device in the coal chemical industry chain, determining the fault type to be a first fault type; calling the emergency response standard associated with the fault type, including: in response to the fault type being the first fault type, determining the emergency response standard to be a gasifier shutdown priority determination standard.

[0064] In this embodiment, if the faulty equipment is a separation device in the coal chemical industry chain, the fault type can be determined to be the first fault type, that is, the sub-control device fault. If the fault type is the first fault type, the emergency handling standard can be determined to be the gasifier shutdown priority determination standard.

[0065] Optionally, the above-mentioned gasifier parking priority determination standard can be simply referred to as the parking priority determination standard, which can be a gasifier determination standard.

[0066] Optionally, a shutdown priority may be set according to the gasifier judgment standard, which may be a gasifier with a short shutdown operation cycle and high operation quality, to ensure that the gasifier is restarted normally.

[0067] Optionally, the judgment criteria may include but are not limited to the following conditions: the gasifier operation cycle, and a set of established gasifier optimal operation scoring criteria (including but not limited to the gasifier operation load and key operation parameters).

[0068] For example, the above emergency response standard may be to give priority to the interlocking and shutdown of gasifiers with short operating cycles and high operating quality scores.

[0069] As an optional implementation, an emergency response strategy corresponding to the fault is determined according to the emergency response standard, including: comparing the emergency response standard with the first load rate of the air separation device to obtain a first comparison result; based on the first comparison result, determining the emergency response strategy, wherein the emergency response strategy is at least used to determine the gasifier to be stopped in at least one gasifier.

[0070] In this embodiment, after the emergency handling standard is determined, the emergency handling standard can be compared with the first load rate of the air separation device to obtain a first comparison result, and the gasifier to be stopped in at least one gasifier can be determined based on the first comparison result.

[0071] Alternatively, if the fault type is an air separation unit fault, at this time, the oxygen and nitrogen production will decrease, and improper handling will cause the gasifier to trip due to low oxygen content and low interlock. Therefore, it is necessary to shut down some gasifiers according to the air separation unit load and the gasifier shutdown priority judgment standard within a limited time to prevent large-scale shutdown of the gasifier. Furthermore, a matching standard can be made according to the load rate of the air separation unit and the number of gasifiers in operation. According to the load rate of the air separation unit, the number of gasifiers that have stopped can be calculated.

[0072] For example, the emergency disposal standard may be: if the air separation load rate is lower than 90%, 2 gasifiers may be stopped; if the air separation load rate is lower than 75%, 5 gasifiers may be stopped; if the air separation load rate is lower than 30%, 10 gasifiers may be stopped. Therefore, by comparing the actual load rate of the air separation unit with the emergency disposal standard, a first comparison result is obtained, and based on the first comparison structure, the number of gasifiers that need to be stopped may be determined.

[0073] As an optional implementation, based on the target device, determining the fault type includes: in response to the target device being a purification device in the coal chemical industry chain, determining the fault type to be a second fault type, wherein the second fault type is different from the first fault type; calling the emergency response standard associated with the fault type, including: in response to the fault type being the second fault type, determining the emergency response standard to be a public medium switching priority determination standard.

[0074] In this embodiment, the purification device may include a fuel gas compressor or a carbon dioxide compressor. If the target device of the fault is a purification device in the coal chemical industry chain, the fault type may be determined to be the second fault type, that is, a purification device fault. Further, in response to the fault type being the second fault type, the emergency handling standard may be determined to be a public medium switching priority determination standard.

[0075] Optionally, a priority determination standard for switching the common medium of the gasification device may be formulated in advance, and the standard may include:

[0076] 1. The criteria for switching the fuel gas (FG) of the gasifier ignition burner to liquefied petroleum gas (LPG) may include:

[0077] 1) Ignition burner operating time;

[0078] 2) Whether the ignition burner is leaking (poor cooling water return flow);

[0079] When the return flow rate difference of the cooling water of the ignition burner is 0 and the running time of the ignition burner is short, automatic switching is prioritized.

[0080] 2. The priority judgment criteria for high-pressure nitrogen and carbon dioxide in the gasifier may include: judging by the main heat loss of the gasifier and the heat loss at the slag mouth, the lower one will be automatically switched first.

[0081] As an optional implementation, an emergency response strategy corresponding to the fault is determined according to the emergency response standard, including: determining the common medium processed by the purification device; determining the second load rate of the common medium; comparing the common medium switching priority judgment standard with the second load rate to obtain a second comparison result; based on the second comparison result, determining the emergency response strategy, wherein the emergency response strategy is at least used to determine the gasifier to be switched in at least one gasifier.

[0082] In this embodiment, a second load rate of the public medium treated by the purification device is determined, and the public medium switching priority judgment standard is compared with the second load rate to obtain a second comparison result; based on the second comparison result, an emergency disposal strategy is determined, and the emergency disposal strategy can be used to determine the gasification furnace to be switched in at least one gasification furnace.

[0083] Optionally, when the fuel gas compressor of the purification device fails, the fuel gas network pressure will drop to the interlock value, which will cause the gasifier interlock to jump. Therefore, it is necessary to switch the ignition burner fuel gas (FG) to LPG in sequence according to the ignition burner operation judgment standard priority within a limited time to avoid large-scale shutdown of the gasifier. Furthermore, a matching standard can be made with the number of gasifiers in operation according to the load rate of the fuel gas system and the number of compressors in operation. According to the fuel gas load rate (that is, the second load rate), the number of gasifiers that need to switch FG to LPG (that is, the number of gasifiers to be switched) can be calculated.

[0084] For example, the pre-set public medium switching priority judgment standard can be: when the fuel gas load rate is lower than 90%, one gasifier FG in each zone switches to LPG, and the burner support purge gas is automatically switched to high-pressure nitrogen by FG ​​at the same time; when the fuel gas load rate is lower than 30%, all gasifier FG switches to LPG, and the burner support purge gas is automatically switched to high-pressure nitrogen by FG ​​at the same time. Therefore, the second load rate of the public medium is obtained, and the public medium switching priority judgment standard is compared with the second load rate to determine the number of gasifiers to be switched.

[0085] In this embodiment, a carbon dioxide compressor failure interlock protection method can also be proposed, which may include: if the carbon dioxide compressor of the purification device fails, it will lead to insufficient carbon dioxide supply to the gasifier. While ensuring the operation of a limited number of gasifiers, the gasifiers can be handled according to priority, while ensuring the stability of the front and rear work sections.

[0086] Optionally, if the carbon dioxide compressor fails, the fault type can be determined to be the second fault type, and the emergency response standard associated with the second fault type can be called, which can be: a matching standard constructed according to the carbon dioxide system load rate and the number of operating carbon dioxide compressors and the number of operating gasifiers.

[0087] Optionally, according to the load rate, the number of gasifiers that are shut down and the number of gasifiers that need to switch from CO2 to high-pressure nitrogen (NH) can be calculated. For example, the standard can be: when the CO2 load rate is lower than 80%, each district switches one gasifier CO2 to NH, and the gasifier load is reduced to 75%, reducing the use of high-pressure nitrogen; when the CO2 load rate is lower than 30%, each district switches two gasifiers CO2 to NH, and the gasifier load is reduced to 75%, reducing the use of high-pressure nitrogen.

Based on the second comparison result, the corresponding emergency disposal strategy can be determined.

It should be noted that the above-mentioned large interlocking protection method can be specifically formulated according to the production failure situation of the device itself, and the emergency response standards corresponding to different fault types can be pre-set to determine the emergency response strategies corresponding to different faults, thereby solving the technical problem of low efficiency of gasifier control and achieving the technical effect of improving the low efficiency of gasifier control.
