Description

Technical Field

[0001] The present application relates to the technical field of valve control, and in particular, to a ceramic feed valve control method, device, electronic equipment and storage medium. Background Art

[0002] In modern coking production process, the control of coal powder feeding at the entrance of the coking chamber is very important, which directly affects the quality and production efficiency of coke products. At present, the widely used coal powder feeding control device is the ceramic feed valve. This valve uses the high temperature resistance and wear resistance of ceramic materials to adapt to the harsh working conditions such as high temperature and dust at the entrance of the coking chamber.

[0003] However, the ceramic feed valve faces severe technical challenges in actual operation. The ambient temperature at the entrance of the carbonization chamber is extremely high, where coal gas and coal powder mix to form a high-temperature, high-concentration mixed gas. This mixed gas will inevitably penetrate into the tiny gap between the sealing surfaces of the ceramic feed valve. Coal gas contains a large amount of tar components, which are very easy to undergo pyrolysis and polymerization reactions under high temperature. After mixing with coal powder particles, a viscous mixture will be formed. When the valve of the ceramic feed valve is closed, the viscous mixture remaining in the gap between the sealing surfaces will gradually cool and harden, and finally solidify into hard coking deposits. These deposits are like gravel, firmly attached to the ceramic sealing surfaces. Since the valve needs to be opened and closed frequently to control the feed amount of coal powder, each opening and closing will cause relative movement between the sealing surfaces. The sediment particles are repeatedly squeezed and rubbed between the sealing surfaces, just like abrasives, accelerating the wear of the ceramic sealing surfaces. What's worse, the presence of sediments will also aggravate the expansion of microcracks on the sealing surface, further damaging the sealing surface, thereby damaging the ceramic feed valve.

[0004] Therefore, in order to solve the technical problem that when using ceramic feed valves in the coking production process, the coking deposits generated in the gap of the sealing surface of the ceramic feed valve will cause valve damage and affect the production efficiency, a ceramic feed valve control method, device, electronic equipment and storage medium are urgently needed. Summary of the invention

[0025] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. At the same time, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0026] Please refer to Figure 1 , Figure 1 A ceramic feed valve control method in some embodiments of the present application is used to control the ceramic feed valve, comprising the steps of: Step S101, obtaining the operating parameters of the ceramic feed valve and the nitrogen input parameters of the nitrogen input system; Step S102, based on a preset deposit reduction rate model, a preset dynamic deposit accumulation model and a preset deposit wear model, combined with operating parameters and nitrogen input parameters, predicting a deposit reduction rate, a deposit accumulation amount and a deposit wear amount; Step S103, designing a nitrogen input strategy according to the deposit reduction rate, deposit accumulation and deposit wear, as well as the composition parameters of the deposit and the structural parameters of the ceramic feed valve, combined with the preset valve sealing reliability target and nitrogen consumption constraint conditions; Step S104, according to the nitrogen input strategy, controlling the ceramic feed valve and the nitrogen input system to clean the deposits.

[0027] The ceramic feed valve control method designs a nitrogen input strategy based on the deposit reduction rate, deposit accumulation amount and deposit wear amount calculated by a preset deposit reduction rate model, a preset dynamic deposit accumulation model and a preset deposit wear model to control the ceramic feed valve and the nitrogen input system to clean the deposits, thereby solving the problem that when the ceramic feed valve is used in a coking production process, the coking deposits generated in the gap of the sealing surface of the ceramic feed valve may cause valve damage and affect production efficiency. The nitrogen input can be dynamically adjusted according to the operating state of the ceramic feed valve and the deposit situation to effectively reduce the deposit accumulation, thereby achieving effective control of the ceramic feed valve.

[0028] Specifically, the nitrogen input system is pre-arranged opposite to the ceramic feed valve, so that the nitrogen output from the nitrogen input system can act on the ceramic feed valve.

[0029] Specifically, in step S101, the operating parameters of the ceramic feed valve and the nitrogen input parameters of the nitrogen input system are obtained, wherein the operating parameters include the valve opening of the ceramic feed valve, the size of the sealing surface gap, the mixed gas flow rate of coal gas and coal powder, the valve inlet pressure, the valve outlet pressure (i.e., the internal pressure of the carbonization chamber), the valve temperature, the valve opening time (i.e., the mixed gas introduction time) and the valve closing time (i.e., the mixed gas introduction time interval), etc., which can reflect the operating status of the valve; the nitrogen input parameters can include the nitrogen input pressure, nitrogen input time and nitrogen input frequency, etc., which can reflect the operating status of the nitrogen input system.

[0030] Specifically, in step S102, the operating parameters and nitrogen input parameters are input into a preset deposit reduction rate model, a preset dynamic deposit accumulation model and a preset deposit wear model, and the predicted deposit reduction rate (the deposit reduction rate is the efficiency of the nitrogen output by the nitrogen input system to purge the deposits to remove the deposits), the deposit accumulation amount and the deposit wear amount (the deposit wear amount is the deposit wear amount caused by the friction of the ceramic valve on the deposits when opening and closing). Among them, the preset deposit reduction rate model is specifically: ; in, is the sediment reduction rate; is the nitrogen purge efficiency coefficient, which is calibrated through experiments or CFD (Computational Fluid Dynamics) simulation; Input pressure for nitrogen; is the pressure inside the carbonization chamber; Indicates nitrogen input pressure The pressure inside the carbonization chamber The maximum value between the difference of When the sediment reduction rate is 0 (i.e. ineffective sweeping), the nitrogen input pressure must be guaranteed to ensure the sediment cleaning effect (i.e. ensure that the sediment reduction rate is greater than 0). Greater than the pressure inside the carbonization chamber ; Enter the time for nitrogen; is the gap size of the sealing surface of the ceramic feed valve; is the natural exponential function, which represents the exponential function with the natural constant e as the base. Indicates e Power.

[0031] The preset dynamic sediment accumulation model is as follows: ; in, It is the amount of deposit generated during a single operation of the valve; is the deposition rate without nitrogen injection, which can be calculated through experiments or field data; is the valve closing time; is the accumulated amount of sediment; n is the total number of valve operation cycles; i is the number of i-th valve operation.

[0032] The preset deposit wear model is as follows: ; in, is the amount of deposit wear; is the wear coefficient, which reflects the wear capacity of the deposits on the valve material; is the wear cycle coefficient, which indicates the effect of valve opening and closing times on wear. and wear cycle coefficient It can be calculated through experiments or field data.

[0033] Specifically, in step S103, according to the deposit reduction rate, the deposit accumulation amount and the deposit wear amount, as well as the composition parameters of the deposit and the structural parameters of the ceramic feed valve, combined with the preset valve sealing reliability target and the nitrogen consumption constraint condition, a nitrogen input strategy is designed, including: Obtaining composition parameters of sediment and structural parameters of ceramic feed valve; According to the composition parameters and structural parameters, combined with the preset valve sealing reliability target and nitrogen consumption constraints, a preliminary nitrogen input strategy is constructed; Based on the deposit reduction rate, deposit accumulation and deposit wear, the preliminary nitrogen input strategy is optimized to obtain the nitrogen input strategy.

[0034] In step S103, the composition parameters of the sediment and the structural parameters of the ceramic feed valve are obtained, wherein the composition parameters are parameters such as tar content and ash content in the sediment that can characterize the characteristics of the sediment, and the structural parameters include parameters such as sealing surface gap distribution or valve material that can characterize the structure of the ceramic feed valve.

[0035] Specifically, in step S103, according to the composition parameters and the structural parameters, combined with the preset valve sealing reliability target and the nitrogen consumption constraint condition, a preliminary nitrogen input strategy is constructed, including: Determine the material properties of the sediment based on the composition parameters; The sealing surface gap distribution of the ceramic feed valve is extracted from the structural parameters; Based on the material properties and the distribution of sealing surface gap, combined with the preset valve sealing reliability target and nitrogen consumption constraints, a preliminary nitrogen input strategy was constructed.

[0036] In step S103, the material properties of the sediment, such as viscosity and hardness, are determined by analyzing the composition parameters of the sediment, such as the tar content. For example, if the tar component in the sediment accounts for a high proportion, the sediment may show a higher viscosity and a lower hardness. When the viscosity of the sediment is high, a higher nitrogen input pressure is required to effectively remove it. Among them, the material properties of the sediment can be obtained by experimental testing, theoretical analysis or empirical data, or the material properties of the sediment are determined by component analysis methods such as spectral analysis and chromatographic analysis, combined with physical property testing methods such as rheological testing and hardness testing. Thus, accurate sediment material property parameters can be obtained, providing a reliable basis for the construction of subsequent nitrogen input strategies.

[0037] By extracting the gap distribution of the sealing surface of the ceramic feed valve, we can understand the areas where nitrogen is easy to enter and difficult to enter, so that we can design a more targeted nitrogen input strategy. For example, for areas with smaller gaps, we can appropriately increase the nitrogen input pressure or extend the nitrogen input time.

[0038] Specifically, in step S103, based on the material properties and the distribution of the sealing surface gap, combined with the preset valve sealing reliability target and the nitrogen consumption constraint condition, a preliminary nitrogen input strategy is constructed, including: Construct an initial preliminary nitrogen input strategy based on preset valve seal reliability targets and nitrogen consumption constraints; Based on the material properties and the distribution of the sealing surface gap, the nitrogen input pressure and the nitrogen input time in the initial preliminary nitrogen input strategy are optimized to obtain a preliminary nitrogen input strategy.

[0039] In step S103, the valve sealing reliability target is the sealing degree that the valve needs to achieve. For example, the valve sealing reliability target can be set to ensure that the valve has no leakage within a certain period of time. The nitrogen consumption constraint condition is the nitrogen consumption limit of the nitrogen input system. For example, the nitrogen consumption constraint condition can be set to that the nitrogen consumption of the nitrogen input system does not exceed a certain value.

[0040] Based on the valve sealing reliability target and the nitrogen consumption constraint, the initial nitrogen input pressure and the initial nitrogen input time are set as the initial preliminary nitrogen input strategy. For example, the initial nitrogen input pressure can be set to a lower pressure value, and the initial nitrogen input time can be set to a shorter time value to meet the basic sealing requirements and nitrogen consumption constraints.

[0041] According to the material properties of the deposits and the distribution of the sealing surface gap of the ceramic feed valve, the nitrogen input pressure and nitrogen input time in the initial preliminary nitrogen input strategy are optimized. For example, if the deposits are easy to clean and the sealing surface gap is large, the initial nitrogen input pressure can be appropriately reduced and the initial nitrogen input time can be appropriately shortened; if the deposits are not easy to clean and the sealing surface gap is small, the initial nitrogen input pressure can be appropriately increased and the initial nitrogen input time can be appropriately extended. Thus, by optimizing the nitrogen input pressure and nitrogen input time, a preliminary nitrogen input strategy is constructed.

[0042] Specifically, in step S103, based on the deposit reduction rate, the deposit accumulation amount and the deposit wear amount, the preliminary nitrogen input strategy is optimized to obtain the nitrogen input strategy, including: When the accumulated amount of deposits is greater than or equal to a preset accumulated amount threshold, the nitrogen input pressure of the nitrogen input system is increased or the nitrogen input time of the nitrogen input system is extended to increase the deposit reduction rate and the deposit wear amount, thereby optimizing the preliminary nitrogen input strategy to obtain the nitrogen input strategy; When the accumulated amount of sediment is less than the preset accumulated amount threshold, determine whether the nitrogen input consumption of the nitrogen input system is greater than the preset nitrogen consumption threshold; if so, reduce the nitrogen input pressure of the nitrogen input system or shorten the nitrogen input time of the nitrogen input system to reduce the nitrogen consumption, thereby optimizing the preliminary nitrogen input strategy to obtain the nitrogen input strategy; if not, maintain the existing nitrogen input pressure and nitrogen input time to obtain the nitrogen input strategy.

[0043] In step S103, the amount of deposit accumulation during the operation of the ceramic feed valve is monitored in real time. When the amount of deposit accumulation reaches or exceeds the preset accumulation threshold, it indicates that the valve has accumulated a lot of deposits. At this time, the control system can increase the nitrogen input pressure of the nitrogen input system, or extend the nitrogen input time of the nitrogen input system. In this way, the nitrogen purge force is increased, thereby increasing the deposit reduction rate and the amount of deposit wear, achieving effective removal of deposits, and ensuring the sealing performance and operational reliability of the ceramic feed valve. Among them, the preset accumulation threshold can be set according to actual needs. For example, for a ceramic feed valve with a large sealing surface gap, the threshold of the deposit accumulation can be appropriately increased; for valves with higher sealing requirements, the threshold can be lowered.

[0044] When the accumulated amount of deposits is lower than the preset accumulated amount threshold, it indicates that the valve deposits are less accumulated. At this time, it is further determined whether the nitrogen consumption of the nitrogen input system exceeds the preset nitrogen consumption threshold. If the nitrogen consumption is too high (i.e., exceeds the preset nitrogen consumption threshold), the nitrogen input pressure can be appropriately reduced or the nitrogen input time can be shortened so that the nitrogen consumption is less than or equal to the preset nitrogen consumption threshold to reduce nitrogen consumption and reduce operating costs. If the nitrogen consumption does not exceed the preset nitrogen consumption threshold, the existing nitrogen input pressure and nitrogen input time are maintained to obtain a nitrogen input strategy. Among them, the preset nitrogen consumption threshold can be set according to actual needs.

[0045] For example, the threshold of deposit accumulation is set to 10 grams. During the operation of the valve, the deposit accumulation is predicted by the preset model. If the predicted deposit accumulation exceeds 10 grams, the control system determines that the deposit accumulation is large and the nitrogen purge effect needs to be enhanced. At this time, the control system can control the nitrogen input system to increase the nitrogen input pressure or extend the nitrogen input time, such as increasing the nitrogen input pressure from 0.2 MPa to 0.3 MPa, or extending the nitrogen input time from 5 seconds to 8 seconds. By increasing the nitrogen input pressure or extending the nitrogen input time, the flushing force of nitrogen on the deposit is enhanced, which can more effectively reduce the accumulation of deposits and accelerate the wear of deposits, thereby ensuring the sealing performance of the valve. On the contrary, if the predicted deposit accumulation is less than 10 grams, the control system further evaluates the nitrogen consumption. Assuming that the preset nitrogen consumption threshold is 5 liters per minute, if the actual nitrogen consumption exceeds 5 liters per minute, the control system determines that the nitrogen consumption is high and there is a possibility of waste. In order to reduce nitrogen consumption, the control system can control the nitrogen input system, reduce the nitrogen input pressure or shorten the nitrogen input time, such as reducing the nitrogen input pressure from 0.3 MPa to 0.25 MPa, or shortening the nitrogen input time from 8 seconds to 6 seconds. If the actual nitrogen consumption does not exceed 5 liters per minute, the existing nitrogen input pressure and nitrogen input time are maintained. By reducing the nitrogen input pressure or shortening the nitrogen input time, the nitrogen consumption can be effectively reduced while ensuring the basic deposit removal effect, thereby achieving the purpose of energy saving and consumption reduction. In this way, the nitrogen input strategy can be adaptively adjusted according to the feedback of the deposit accumulation and nitrogen consumption, making the nitrogen input control more refined and intelligent.

[0046] In practical applications, the optimal sediment accumulation threshold and nitrogen consumption threshold, as well as the adjustment range of nitrogen input pressure and nitrogen input time can be determined through experiments or simulations.

[0047] Specifically, in step S104, according to the nitrogen input strategy, the ceramic feed valve and the nitrogen input system are controlled to clean the deposits, including: Control the nitrogen input system to execute the nitrogen input strategy to clean the deposits while obtaining the real-time flow rate of the mixed gas of coal gas and coal powder when passing through the ceramic feed valve; The valve opening of the ceramic feed valve is adjusted so that the real-time flow rate tends to the preset coking production target flow rate.

[0048] In step S104, the nitrogen input system is driven to output nitrogen according to parameters such as nitrogen input pressure and nitrogen input time in the nitrogen input strategy to clean the deposits on the ceramic feed valve. At the same time, the flow rate of the coal gas and coal powder mixed gas is monitored in real time through a flow sensor installed downstream of the ceramic feed valve.

[0049] In actual applications, in coking production tasks, the preset coking production target flow rate will be determined according to the coking production plan and process parameters, and the input of nitrogen will affect the flow rate of the mixed gas of coal gas and coal powder, that is, it will affect the flow rate of the mixed gas. Therefore, in order to ensure the normal operation of the coking production task, it is necessary to adjust the valve opening of the ceramic feed valve to maintain the stable operation of the coking production process.

[0050] Specifically, in step S104, adjusting the valve opening of the ceramic feed valve so that the real-time flow rate tends to the preset coking production target flow rate includes: Calculate the deviation between the real-time flow and the preset coking production target flow; The valve opening of the ceramic feed valve is adjusted based on the deviation value using the PID algorithm.

[0051] In step S104, the real-time flow rate is compared with the preset coking production target flow rate, and the deviation value between the two is calculated. This deviation value directly reflects the degree of deviation between the current flow rate and the target flow rate. Subsequently, the deviation value is input into the preset PID algorithm. The PID algorithm calculates the adjustment amount of the valve opening according to the size and direction of the deviation value and the set control law. The calculated valve opening adjustment amount is converted into a control signal and sent to the valve actuator of the ceramic feed valve. After receiving the control signal, the valve actuator drives the valve stem to move and accurately adjust the valve opening of the ceramic feed valve. The change in valve opening will directly affect the flow rate of the mixed gas of coal gas and coal powder. If the real-time flow rate is too small, the PID algorithm will control the valve actuator to increase the valve opening, thereby increasing the flow rate; conversely, if the real-time flow rate is too large, the PID algorithm will control the valve actuator to reduce the valve opening, thereby reducing the flow rate. Through the above closed-loop control process, the real-time flow rate is continuously adjusted and finally stabilized near the preset coking production target flow rate, thereby achieving precise control of the flow rate and ensuring that the mixed gas flow rate of coal gas and coal powder meets the coking production target flow rate. Among them, the PID algorithm is an existing algorithm and will not be described in detail here.

[0052] In some optional embodiments, a corresponding PID controller can be generated in advance according to the PID algorithm. After calculating the deviation value between the real-time flow rate and the preset coking production target flow rate, the PID controller will automatically adjust the valve opening of the ceramic feed valve according to the deviation value to maintain the stable operation of the coking production process.

[0053] As can be seen from the above, the ceramic feed valve control method obtains the operating parameters of the ceramic feed valve and the nitrogen input parameters of the nitrogen input system, based on the preset deposit reduction rate model, the preset dynamic deposit accumulation model and the preset deposit wear model, combined with the operating parameters and the nitrogen input parameters, predicts the deposit reduction rate, the deposit accumulation amount and the deposit wear amount, and designs a nitrogen input strategy based on the deposit reduction rate, the deposit accumulation amount and the deposit wear amount, as well as the composition parameters of the deposit and the structural parameters of the ceramic feed valve, combined with the preset valve sealing reliability target and the nitrogen consumption constraint conditions, and controls the ceramic feed valve and the nitrogen according to the nitrogen input strategy. An input system is provided to clean the deposits; thereby, the deposit reduction rate, deposit accumulation amount and deposit wear amount calculated by a preset deposit reduction rate model, a preset dynamic deposit accumulation model and a preset deposit wear model are used to design a nitrogen input strategy to control the ceramic feed valve and the nitrogen input system to clean the deposits, so as to solve the problem that when the ceramic feed valve is used in the coking production process, the coking deposits generated in the sealing surface gap of the ceramic feed valve may cause valve damage and affect the production efficiency. The nitrogen input can be dynamically adjusted according to the operating status and deposit situation of the ceramic feed valve to effectively reduce the deposit accumulation, thereby realizing effective control of the ceramic feed valve.

[0054] refer to Figure 2 The present application provides a ceramic feed valve control device for controlling a ceramic feed valve, comprising: An acquisition module 1 is used to acquire the operating parameters of the ceramic feed valve and the nitrogen input parameters of the nitrogen input system; Prediction module 2, used for predicting the deposit reduction rate, the deposit accumulation amount and the deposit wear amount based on a preset deposit reduction rate model, a preset dynamic deposit accumulation model and a preset deposit wear model, combined with operating parameters and nitrogen input parameters; Design module 3, used to design a nitrogen input strategy according to the deposit reduction rate, deposit accumulation and deposit wear, as well as the composition parameters of the deposits and the structural parameters of the ceramic feed valve, combined with the preset valve sealing reliability target and nitrogen consumption constraint conditions; The control module 4 is used to control the ceramic feed valve and the nitrogen input system according to the nitrogen input strategy to clean the deposits.

[0055] The ceramic feed valve control device designs a nitrogen input strategy based on the deposit reduction rate, deposit accumulation amount and deposit wear amount calculated by a preset deposit reduction rate model, a preset dynamic deposit accumulation model and a preset deposit wear model to control the ceramic feed valve and the nitrogen input system to clean the deposits, thereby solving the problem that when the ceramic feed valve is used in a coking production process, the coking deposits generated in the gap between the sealing surfaces of the ceramic feed valve may cause valve damage and affect production efficiency. The nitrogen input can be dynamically adjusted according to the operating state of the ceramic feed valve and the deposit situation to effectively reduce the deposit accumulation, thereby achieving effective control of the ceramic feed valve.

[0056] Specifically, the nitrogen input system is pre-arranged opposite to the ceramic feed valve, so that the nitrogen output from the nitrogen input system can act on the ceramic feed valve.

[0057] Specifically, when the acquisition module 1 is executed, the operating parameters of the ceramic feed valve and the nitrogen input parameters of the nitrogen input system are acquired, wherein the operating parameters include the valve opening of the ceramic feed valve, the size of the sealing surface gap, the mixed gas flow rate of coal gas and coal powder, the valve inlet pressure, the valve outlet pressure (i.e., the pressure inside the carbonization chamber), the valve temperature, the valve opening time (i.e., the mixed gas introduction time) and the valve closing time (i.e., the mixed gas introduction time interval), etc., which can reflect the valve operating status; the nitrogen input parameters can include the nitrogen input pressure, nitrogen input time and nitrogen input frequency, etc., which can reflect the operating status of the nitrogen input system.

[0058] Specifically, when the prediction module 2 is executed, the operation parameters and the nitrogen input parameters are input into the preset deposit reduction rate model, the preset dynamic deposit accumulation model and the preset deposit wear model, and the predicted deposit reduction rate (the deposit reduction rate is the efficiency of the nitrogen output by the nitrogen input system to purge the deposits to remove the deposits), the deposit accumulation amount and the deposit wear amount (the deposit wear amount is the deposit wear amount caused by the friction of the ceramic valve on the deposits when opening and closing). Among them, the preset deposit reduction rate model is specifically: ; in, is the sediment reduction rate; is the nitrogen purge efficiency coefficient, which is calibrated through experiments or CFD (Computational Fluid Dynamics) simulation; Input pressure for nitrogen; is the pressure inside the carbonization chamber; Indicates nitrogen input pressure The pressure inside the carbonization chamber The maximum value between the difference of When the sediment reduction rate is 0 (i.e. ineffective sweeping), the nitrogen input pressure must be guaranteed to ensure the sediment cleaning effect (i.e. ensure that the sediment reduction rate is greater than 0). Greater than the pressure inside the carbonization chamber ; Enter the time for nitrogen; is the gap size of the sealing surface of the ceramic feed valve; is the natural exponential function, which represents the exponential function with the natural constant e as the base. Indicates e Power.

[0059] The preset dynamic sediment accumulation model is as follows: ; in, It is the amount of deposit generated during a single operation of the valve; is the deposition rate without nitrogen injection, which can be calculated through experiments or field data; is the valve closing time; is the accumulated amount of sediment; n is the total number of valve operation cycles; i is the number of i-th valve operation.

[0060] The preset deposit wear model is as follows: ; in, is the amount of deposit wear; is the wear coefficient, which reflects the wear capacity of the deposits on the valve material; is the wear cycle coefficient, which indicates the effect of valve opening and closing times on wear. and wear cycle coefficient It can be calculated through experiments or field data.

[0061] Specifically, when designing the nitrogen input strategy according to the deposit reduction rate, the deposit accumulation amount and the deposit wear amount, as well as the composition parameters of the deposit and the structural parameters of the ceramic feed valve, combined with the preset valve sealing reliability target and the nitrogen consumption constraint condition, the design module 3 executes: Obtaining composition parameters of sediment and structural parameters of ceramic feed valve; According to the composition parameters and structural parameters, combined with the preset valve sealing reliability target and nitrogen consumption constraints, a preliminary nitrogen input strategy is constructed; Based on the deposit reduction rate, deposit accumulation and deposit wear, the preliminary nitrogen input strategy is optimized to obtain the nitrogen input strategy.

[0062] When the design module 3 is executed, it obtains the composition parameters of the sediment and the structural parameters of the ceramic feed valve, wherein the composition parameters are parameters such as tar content and ash content in the sediment that can characterize the characteristics of the sediment, and the structural parameters include parameters such as sealing surface gap distribution or valve material that can characterize the structure of the ceramic feed valve.

[0063] Specifically, when the design module 3 constructs a preliminary nitrogen input strategy based on the composition parameters and the structural parameters, combined with the preset valve sealing reliability target and the nitrogen consumption constraint conditions, it executes: Determine the material properties of the sediment based on the composition parameters; The sealing surface gap distribution of the ceramic feed valve is extracted from the structural parameters; Based on the material properties and the distribution of sealing surface gap, combined with the preset valve sealing reliability target and nitrogen consumption constraints, a preliminary nitrogen input strategy was constructed.

[0064] When the design module 3 is executed, the viscosity, hardness and other material properties of the sediment are determined by analyzing the composition parameters of the sediment, such as the tar content. For example, if the tar component in the sediment accounts for a high proportion, the sediment may show a higher viscosity and a lower hardness. When the sediment viscosity is high, a higher nitrogen input pressure is required to effectively remove it. Among them, the material properties of the sediment can be obtained by experimental testing, theoretical analysis or empirical data, or the material properties of the sediment are determined by component analysis methods such as spectral analysis and chromatographic analysis, combined with physical property testing methods such as rheological testing and hardness testing. Thus, accurate sediment material property parameters can be obtained, providing a reliable basis for the construction of subsequent nitrogen input strategies.

[0065] By extracting the gap distribution of the sealing surface of the ceramic feed valve, we can understand the areas where nitrogen is easy to enter and difficult to enter, so that we can design a more targeted nitrogen input strategy. For example, for areas with smaller gaps, we can appropriately increase the nitrogen input pressure or extend the nitrogen input time.

[0066] Specifically, when the design module 3 constructs a preliminary nitrogen input strategy based on the material properties and the distribution of the sealing surface gap, combined with the preset valve sealing reliability target and the nitrogen consumption constraint condition, it executes: Construct an initial preliminary nitrogen input strategy based on preset valve seal reliability targets and nitrogen consumption constraints; Based on the material properties and the distribution of the sealing surface gap, the nitrogen input pressure and the nitrogen input time in the initial preliminary nitrogen input strategy are optimized to obtain a preliminary nitrogen input strategy.

[0067] When the design module 3 is executed, the valve sealing reliability target is the sealing degree that the valve needs to achieve. For example, the valve sealing reliability target can be set to ensure that the valve has no leakage within a certain period of time. The nitrogen consumption constraint condition is the nitrogen consumption limit of the nitrogen input system. For example, the nitrogen consumption constraint condition can be set to that the nitrogen consumption of the nitrogen input system does not exceed a certain value.

[0068] Based on the valve sealing reliability target and the nitrogen consumption constraint, the initial nitrogen input pressure and the initial nitrogen input time are set as the initial preliminary nitrogen input strategy. For example, the initial nitrogen input pressure can be set to a lower pressure value, and the initial nitrogen input time can be set to a shorter time value to meet the basic sealing requirements and nitrogen consumption constraints.

[0069] According to the material properties of the deposits and the distribution of the sealing surface gap of the ceramic feed valve, the nitrogen input pressure and nitrogen input time in the initial preliminary nitrogen input strategy are optimized. For example, if the deposits are easy to clean and the sealing surface gap is large, the initial nitrogen input pressure can be appropriately reduced and the initial nitrogen input time can be appropriately shortened; if the deposits are not easy to clean and the sealing surface gap is small, the initial nitrogen input pressure can be appropriately increased and the initial nitrogen input time can be appropriately extended. Thus, by optimizing the nitrogen input pressure and nitrogen input time, a preliminary nitrogen input strategy is constructed.

[0070] Specifically, when the design module 3 optimizes the preliminary nitrogen input strategy based on the deposit reduction rate, the deposit accumulation amount and the deposit wear amount and obtains the nitrogen input strategy, it executes: When the accumulated amount of deposits is greater than or equal to a preset accumulated amount threshold, the nitrogen input pressure of the nitrogen input system is increased or the nitrogen input time of the nitrogen input system is extended to increase the deposit reduction rate and the deposit wear amount, thereby optimizing the preliminary nitrogen input strategy to obtain the nitrogen input strategy; When the accumulated amount of sediment is less than the preset accumulated amount threshold, determine whether the nitrogen input consumption of the nitrogen input system is greater than the preset nitrogen consumption threshold; if so, reduce the nitrogen input pressure of the nitrogen input system or shorten the nitrogen input time of the nitrogen input system to reduce the nitrogen consumption, thereby optimizing the preliminary nitrogen input strategy to obtain the nitrogen input strategy; if not, maintain the existing nitrogen input pressure and nitrogen input time to obtain the nitrogen input strategy.

[0071] When the design module 3 is executed, the accumulated amount of deposits during the operation of the ceramic feed valve is monitored in real time. When the accumulated amount of deposits reaches or exceeds the preset accumulated amount threshold, it indicates that the valve has accumulated a lot of deposits. At this time, the control system can increase the nitrogen input pressure of the nitrogen input system, or extend the nitrogen input time of the nitrogen input system. In this way, the nitrogen purge force is increased, thereby increasing the deposit reduction rate and the amount of deposit wear, achieving effective removal of deposits, and ensuring the sealing performance and operational reliability of the ceramic feed valve. Among them, the preset accumulated amount threshold can be set according to actual needs. For example, for a ceramic feed valve with a large sealing surface gap, the accumulated amount threshold can be appropriately increased; for valves with higher sealing requirements, the threshold can be lowered.

[0072] When the accumulated amount of deposits is lower than the preset accumulated amount threshold, it indicates that the valve deposits are less accumulated. At this time, it is further determined whether the nitrogen consumption of the nitrogen input system exceeds the preset nitrogen consumption threshold. If the nitrogen consumption is too high (i.e., exceeds the preset nitrogen consumption threshold), the nitrogen input pressure can be appropriately reduced or the nitrogen input time can be shortened so that the nitrogen consumption is less than or equal to the preset nitrogen consumption threshold to reduce nitrogen consumption and reduce operating costs. If the nitrogen consumption does not exceed the preset nitrogen consumption threshold, the existing nitrogen input pressure and nitrogen input time are maintained to obtain a nitrogen input strategy. Among them, the preset nitrogen consumption threshold can be set according to actual needs.

[0073] For example, the threshold of deposit accumulation is set to 10 grams. During the operation of the valve, the deposit accumulation is predicted by the preset model. If the predicted deposit accumulation exceeds 10 grams, the control system determines that the deposit accumulation is large and the nitrogen purge effect needs to be enhanced. At this time, the control system can control the nitrogen input system to increase the nitrogen input pressure or extend the nitrogen input time, such as increasing the nitrogen input pressure from 0.2 MPa to 0.3 MPa, or extending the nitrogen input time from 5 seconds to 8 seconds. By increasing the nitrogen input pressure or extending the nitrogen input time, the flushing force of nitrogen on the deposit is enhanced, which can more effectively reduce the accumulation of deposits and accelerate the wear of deposits, thereby ensuring the sealing performance of the valve. On the contrary, if the predicted deposit accumulation is less than 10 grams, the control system further evaluates the nitrogen consumption. Assuming that the preset nitrogen consumption threshold is 5 liters per minute, if the actual nitrogen consumption exceeds 5 liters per minute, the control system determines that the nitrogen consumption is high and there is a possibility of waste. In order to reduce nitrogen consumption, the control system can control the nitrogen input system, reduce the nitrogen input pressure or shorten the nitrogen input time, such as reducing the nitrogen input pressure from 0.3 MPa to 0.25 MPa, or shortening the nitrogen input time from 8 seconds to 6 seconds. If the actual nitrogen consumption does not exceed 5 liters per minute, the existing nitrogen input pressure and nitrogen input time are maintained. By reducing the nitrogen input pressure or shortening the nitrogen input time, the nitrogen consumption can be effectively reduced while ensuring the basic deposit removal effect, thereby achieving the purpose of energy saving and consumption reduction. In this way, the nitrogen input strategy can be adaptively adjusted according to the feedback of the deposit accumulation and nitrogen consumption, making the nitrogen input control more refined and intelligent.

[0074] In practical applications, the optimal sediment accumulation threshold and nitrogen consumption threshold, as well as the adjustment range of nitrogen input pressure and nitrogen input time can be determined through experiments or simulations.

[0075] Specifically, when the control module 4 controls the ceramic feed valve and the nitrogen input system according to the nitrogen input strategy to clean the deposits, it executes: Control the nitrogen input system to execute the nitrogen input strategy to clean the deposits while obtaining the real-time flow rate of the mixed gas of coal gas and coal powder when passing through the ceramic feed valve; The valve opening of the ceramic feed valve is adjusted so that the real-time flow rate tends to the preset coking production target flow rate.

[0076] When the control module 4 is executed, it drives the nitrogen input system to output nitrogen according to the parameters such as nitrogen input pressure and nitrogen input time in the nitrogen input strategy to clean the deposits of the ceramic feed valve. At the same time, the flow rate of the coal gas and coal powder mixed gas is monitored in real time through the flow sensor installed downstream of the ceramic feed valve.

[0077] In actual applications, in coking production tasks, the preset coking production target flow rate will be determined according to the coking production plan and process parameters, and the input of nitrogen will affect the flow rate of the mixed gas of coal gas and coal powder, that is, it will affect the flow rate of the mixed gas. Therefore, in order to ensure the normal operation of the coking production task, it is necessary to adjust the valve opening of the ceramic feed valve to maintain the stable operation of the coking production process.

[0078] Specifically, when the control module 4 adjusts the valve opening of the ceramic feed valve so that the real-time flow rate tends to the preset coking production target flow rate, it executes: Calculate the deviation between the real-time flow and the preset coking production target flow; The valve opening of the ceramic feed valve is adjusted based on the deviation value using the PID algorithm.

[0079] When the control module 4 is executed, the real-time flow rate is compared with the preset coking production target flow rate, and the deviation value between the two is calculated. This deviation value directly reflects the degree of deviation between the current flow rate and the target flow rate. Subsequently, the deviation value is input into the preset PID algorithm. The PID algorithm calculates the adjustment amount of the valve opening according to the size and direction of the deviation value and the set control law. The calculated valve opening adjustment amount is converted into a control signal and sent to the valve actuator of the ceramic feed valve. After receiving the control signal, the valve actuator drives the valve stem to move and accurately adjust the valve opening of the ceramic feed valve. The change in valve opening will directly affect the flow rate of the mixed gas of coal gas and coal powder. If the real-time flow rate is too small, the PID algorithm will control the valve actuator to increase the valve opening, thereby increasing the flow rate; conversely, if the real-time flow rate is too large, the PID algorithm will control the valve actuator to reduce the valve opening, thereby reducing the flow rate. Through the above closed-loop control process, the real-time flow rate is continuously adjusted and finally stabilized near the preset coking production target flow rate, thereby achieving precise control of the flow rate and ensuring that the mixed gas flow rate of coal gas and coal powder meets the coking production target flow rate. Among them, the PID algorithm is an existing algorithm and will not be described in detail here.

[0080] In some optional embodiments, a corresponding PID controller can be generated in advance according to the PID algorithm. After the control module 4 calculates the deviation value between the real-time flow rate and the preset coking production target flow rate, it drives the PID controller to automatically adjust the valve opening of the ceramic feed valve according to the deviation value to maintain the stable operation of the coking production process.

[0081] As can be seen from the above, the ceramic feed valve control device obtains the operating parameters of the ceramic feed valve and the nitrogen input parameters of the nitrogen input system, and based on the preset deposit reduction rate model, the preset dynamic deposit accumulation model and the preset deposit wear model, combined with the operating parameters and the nitrogen input parameters, predicts the deposit reduction rate, the deposit accumulation amount and the deposit wear amount, and designs a nitrogen input strategy based on the deposit reduction rate, the deposit accumulation amount and the deposit wear amount, as well as the composition parameters of the deposit and the structural parameters of the ceramic feed valve, combined with the preset valve sealing reliability target and the nitrogen consumption constraint conditions, and controls the ceramic feed valve and the nitrogen according to the nitrogen input strategy. An input system is provided to clean the deposits; thereby, the deposit reduction rate, deposit accumulation amount and deposit wear amount calculated by a preset deposit reduction rate model, a preset dynamic deposit accumulation model and a preset deposit wear model are used to design a nitrogen input strategy to control the ceramic feed valve and the nitrogen input system to clean the deposits, so as to solve the problem that when the ceramic feed valve is used in the coking production process, the coking deposits generated in the sealing surface gap of the ceramic feed valve may cause valve damage and affect the production efficiency. The nitrogen input can be dynamically adjusted according to the operating status and deposit situation of the ceramic feed valve to effectively reduce the deposit accumulation, thereby realizing effective control of the ceramic feed valve.
