Description

Technical Field

[0001] This disclosure relates to the field of electrical equipment technology, specifically to an ash silo gasification air system, a control method for the ash silo gasification air system, a control device for the ash silo gasification air system, a non-transitory computer-readable storage medium, electronic equipment, and computer program products. Background Technology

[0002] Coal-fired power plants typically have ash silos to store and transport post-combustion ash from boiler flue gas that has been removed by electrostatic precipitators, thus enabling the storage and external transportation of ash for comprehensive utilization within the power plant. To ensure that the ash remains in a fluidized state for easy discharge and transportation, gasifying air is blown into the ash silos by gasifying fans. This increases the fluidity of the ash and prevents it from caking.

[0003] In related technologies, coal-fired power plants typically install a gasification blower to supply gasification air to a corresponding ash silo, and the flow rate of the gasification air is fixed. To meet the gas supply needs of the ash silo, the flow rate of the gasification air provided by the gasification blower is usually set based on the maximum material level of the ash silo to prevent insufficient gas supply when the ash content in the ash silo is high, which could lead to ash caking. However, since the ash silo level is constantly changing due to factors such as unit load and ash transportation, this gas supply method has poor flexibility and is prone to resource waste due to excessive gasification air flow.

[0028] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0029] It should be noted that all actions involving the acquisition of signals, information, or data in this disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the location is situated, and with authorization from the owner of the relevant device.

[0030] In this disclosure, unless otherwise stated, directional terms such as "top" and "bottom" generally refer to the top and bottom of the corresponding component in the direction of gravity when in use, and "inner" and "outer" refer to the inner and outer contours relative to the component or structure itself. Furthermore, it should be noted that terms such as "first" and "second" are used to distinguish one element from another and do not have sequential or importance implications. Additionally, in the description with reference to the accompanying drawings, the same reference numerals in different drawings denote the same element.

[0031] Figure 1 This is a schematic diagram illustrating the structure of an ash silo gasification air system according to an exemplary embodiment. For example... Figure 1 As shown, this disclosure provides an ash silo gasification ventilation system, comprising: at least three target ash silos 10, the at least three target ash silos 10 being connected in parallel to one end of a main pipe 12 via ash silo branch pipes 11, and each target ash silo 10 being connected to an ash silo branch pipe 11 being provided with a target gas regulating valve 20, the target gas regulating valve 20 being used to regulate the gas flow rate supplied to the at least three target ash silos 10 through the ash silo branch pipe 11; and a target fan assembly 30, the target fan assembly 30 being connected to the other end of the main pipe 12 via a pipe, the target fan assembly 30 being used to supply gas to the at least three target ash silos 10 sequentially through the pipe, the main pipe 12, and the ash silo branch pipe 11 when powered on.

[0032] For example, the target gas regulating valve 20 may include a manually operated regulating valve or an electrically operated regulating valve, which is not limited in this disclosure.

[0033] Through the above technical solution, in the ash silo gasification ventilation system provided by this disclosure, at least three target ash silos 10 are connected in parallel to one end of the main pipe 12 via ash silo branch pipes 11, and the target fan assembly 30 is connected to the other end of the main pipe 12 via a pipeline. In this way, the target fan assembly 30 can supply gas to at least three target ash silos 10 through the pipeline, the main pipe 12, and the ash silo branch pipes 11, thereby keeping the ash in the target ash silos 10 in a flowing state, facilitating the discharge and transportation of ash. Furthermore, a target gas regulating valve 20 is provided on the ash silo branch pipe 11 connected to each target ash silo 10. The target gas regulating valve 20 can regulate the gas flow rate supplied to the at least three target ash silos 10 through the ash silo branch pipe 11. Thus, the gas supply can be flexibly adjusted according to the needs of different target ash silos 10, ensuring that each target ash silo 10 receives an appropriate amount of gas, meeting the gas supply needs of the target ash silos 10 while avoiding the waste of gas resources due to excessive gas supply from the target fan assembly 30.

[0034] Optionally, at least three target ash silos 10 include a primary ash silo 101, a coarse ash silo 102, and a fine ash silo 103. The target gas regulating valve 20 includes at least a first gas regulating valve 201 on the ash silo branch pipe 11 connected to the primary ash silo 101, a second gas regulating valve 202 on the ash silo branch pipe 11 connected to the coarse ash silo 102, and a third gas regulating valve 203 on the ash silo branch pipe 11 connected to the fine ash silo 103. Thus, the first gas regulating valve 201 can regulate the gas flow rate supplied to the primary ash silo 101 via the ash silo branch pipe 11; the second gas regulating valve 202 can regulate the gas flow rate supplied to the coarse ash silo 102 via the ash silo branch pipe 11; and the third gas regulating valve 203 can regulate the gas flow rate supplied to the fine ash silo 103 via the ash silo branch pipe 11.

[0035] Understandably, since each target ash silo 10 is equipped with a corresponding gas regulating valve, the valve opening of the corresponding gas regulating valve can be adjusted according to the needs of different target ash silos 10 to control the gas flow rate supplied to different target ash silos 10, thereby enabling the gas supply of the target fan assembly 30 to meet the needs of different target ash silos 10 and improving the flexibility of the ash silo gasification air system.

[0036] For example, at least three target ash silos 10 may also include other ash silos, which can be set according to user needs and are not limited here. Correspondingly, each ash silo branch pipe 11 connected to each ash silo can be equipped with a corresponding gas regulating valve to regulate the gas flow rate supplied to the corresponding ash silo through the ash silo branch pipe 11.

[0037] Optionally, a first manual valve 41 is also installed on the ash silo branch pipe 11 between the original ash silo 101 and the first gas regulating valve 201; a second manual valve 42 is also installed on the ash silo branch pipe 11 between the coarse ash silo 102 and the second gas regulating valve 202; and a third manual valve 43 is also installed on the ash silo branch pipe 11 between the fine ash silo 103 and the third gas regulating valve 203. The first manual valve 41, the second manual valve 42, and the third manual valve 43 can respectively control the gas supply from the target fan assembly 30 to the original ash silo 101, to the coarse ash silo 102, and to the fine ash silo 103. Taking the first manual valve 41 as an example, when the first manual valve 41 is in the open state, the gas supplied by the target fan assembly 30 can be delivered to the original ash silo 101, that is, the target fan assembly 30 can supply gas to the original ash silo 101; when the first manual valve 41 is in the closed state, the gas supplied by the target fan assembly 30 cannot be delivered to the original ash silo 101, that is, the target fan assembly 30 cannot supply gas to the original ash silo 101.

[0038] By setting the first manual valve 41, the second manual valve 42, and the third manual valve 43, the gas supply process of the ash silo gasification air system can be effectively managed. When gas supply is not required, closing the manual valves can avoid unnecessary consumption of gas supply resources and save gas supply resources of the ash silo gasification air system.

[0039] Optionally, the target fan assembly 30 includes multiple base fan assemblies 31 connected in parallel via pipes. Each base fan assembly 31 includes a gasifying fan 311, a check valve 312, an electric heater 313, and an outlet valve 314 connected in sequence via pipes.

[0040] Among them, the gasification fan 311 is used to provide gasification air when it is turned on, that is, to provide gas supply; the check valve 312 is used to prevent the gas supply provided by the gasification fan 311 from flowing back in the pipeline, thereby improving the safety and stability of the gas supply process; the electric heater 313 is used to heat the temperature of the gas supply to a preset temperature (e.g., 90°C, 100°C), so that the ash in at least three target ash silos 10 can maintain a good flow state under the gas supply at the preset temperature; the outlet valve 314 can cut off the airflow when closed, and is suitable for scenarios such as maintenance or repair of the target fan assembly 30 or other equipment.

[0041] For example, such as Figure 1As shown, the number of basic fan components 31 can be four, and any one of the basic fan components 31 can be set as a backup fan component. In this way, during the operation of the ash silo gasification air system, air can be supplied to at least three target ash silos 10 through three basic fan components 31, and if any of the basic fan components 31 used for air supply fails, the backup fan component can be started to take over the failed basic fan component 31 to ensure the stability of the ash silo gasification air system during operation.

[0042] Please continue to refer to Figure 2 , Figure 2 This is a flowchart illustrating a control method for an ash silo gasification air system according to an exemplary embodiment. Figure 2 As shown, the control method for the ash silo gasification air system can be applied to the ash silo gasification air system provided in this disclosure, and can be executed by the control unit (e.g., microcontroller unit, distributed control unit, etc.) on the ash silo gasification air system. The control method for the ash silo gasification air system may include the following steps: In step S11, the current number of operating fans of the target fan assembly 30 and the current material level data of at least three target ash silos 10 are obtained.

[0043] It should be noted that the current number of operating fans in the target fan assembly 30 can be preset by the user. That is, the user can set the current number of operating fans in the target fan assembly 30 to 2, 3, etc., according to actual needs, and control the target fan assembly 30 to operate according to the preset number during actual operation. There is no limitation here.

[0044] For example, a level sensor (e.g., ultrasonic sensor, radar sensor, capacitive sensor, etc.) can be installed in each target ash silo 10 to measure the ash level within the target ash silo 10 in real time. Thus, the current ash level data of the corresponding target ash silo 10 can be determined based on the measurement results of the level sensor.

[0045] In step S12, the recommended number of operating fans for the target fan assembly 30 is determined based on the current material level data.

[0046] The recommended number of operating fans is used to characterize the number of fans that are recommended to be operated to meet the air supply requirements of the target ash silo 10 under the current material level data.

[0047] In some implementations, the total gas supply demand for at least three target ash silos 10 can be determined based on the current material level data. Then, the recommended number of operating fans for the target fan assembly 30 can be determined based on the total gas supply demand of the at least three target ash silos 10 and the gas supply capacity of the target fan assembly 30. For example, the current material level data for each target ash silo 10 can be determined, and the corresponding gas supply demand for that target ash silo 10 can be determined based on the current material level data. Thus, the total gas supply demand for at least three target ash silos 10 can be calculated based on the gas supply demand corresponding to each target ash silo 10. Furthermore, the gas supply capacity of the target fan assembly 30 (i.e., the gas supply capacity of any one fan in the target fan assembly 30) can be obtained. Then, the recommended number of operating fans for the target fan assembly 30 can be obtained by dividing the total gas supply demand of the at least three target ash silos 10 by the gas supply capacity of the target fan assembly 30.

[0048] In other implementations, the total material level data level can be preset, such as low, medium, and high levels. Furthermore, a recommended number of operating fans can be set according to different total material level data levels. For example, when the total material level data level is low, the recommended number of operating fans is set to 1; when the total material level data level is medium, the recommended number of operating fans is set to 2; and when the total material level data level is high, the recommended number of operating fans is set to 3. Thus, the total material level data level can be determined based on the current material level data, and the corresponding recommended number of operating fans can be further determined.

[0049] In step S13, the valve opening data of the target gas regulating valve 20 is determined based on the recommended number of operating fans and the current number of operating fans.

[0050] In some implementations, the flow rate difference of the supplied gas can be determined based on the difference between the recommended number of operating fans and the current number of operating fans, as well as the gas supply capacity of the target fan assembly 30. This flow rate difference is then used to determine the valve opening data of the target gas regulating valve 20. For example, the correspondence between the valve opening data adjustment amount and the supply gas flow rate difference can be pre-acquired. Therefore, the valve opening data adjustment amount can be determined based on the supply gas flow rate difference, and the valve opening data of the target gas regulating valve 20 can be determined based on the initial valve opening data and the valve opening data adjustment amount. For instance, suppose the pre-acquired correspondence between the valve opening data adjustment amount and the supply gas flow rate difference is such that for every 50 units increase (or decrease) in the gas flow rate difference, the corresponding valve opening adjustment amount increases (or decreases) by 10%, and the acquired initial valve opening data is 40%. If the current number of operating fans is 2 and the recommended number of operating fans is 3, then the difference is 1 fan. Therefore, the product of this difference and the air supply capacity of the target fan assembly 30 (e.g., 50 units) can be determined as the difference in gas flow rate. Furthermore, in response to a higher recommended number of operating fans than the current number, the valve opening of the target gas regulating valve 20 can be determined to be 50%. If the current number of operating fans is 3 and the recommended number of operating fans is 2, then the difference is 1 fan. Therefore, the product of this difference and the air supply capacity of the target fan assembly 30 (e.g., 50 units) can be determined as the difference in gas flow rate. Furthermore, in response to a lower recommended number of operating fans than the current number, the valve opening of the target gas regulating valve 20 can be determined to be 30%.

[0051] In other embodiments, if the gas supply flow rate and valve opening data are linearly related, the gas supply flow rate ratio can be determined based on the ratio of the recommended number of operating fans to the current number of operating fans, and then the valve opening data of the target gas regulating valve 20 can be determined based on the gas supply flow rate ratio. For example, when the recommended number of operating fans is 3 and the current number of operating fans is 2, the gas supply flow rate ratio can be determined to be 3:2. In order to ensure that the gas supply flow rate of the current number of operating fans can reach the gas supply flow rate of the recommended number of operating fans, the valve opening data can be determined to be 1.5 times the initial valve opening data. ).

[0052] In step S14, the target gas regulating valve 20 is controlled to operate according to the valve opening data to regulate the gas flow rate supplied to at least three target ash silos 10.

[0053] Understandably, the above method can control the gas flow rate supplied to at least three target ash silos 10 by controlling the target gas regulating valve 20 to operate according to the valve opening data, so that the gas supply of the target fan assembly 30 can meet the needs of different target ash silos 10, thereby improving the flexibility of the ash silo gasification air system.

[0054] Through the above technical solution, the control method of the ash silo gasification ventilation system provided in this disclosure can determine the recommended number of operating fans to meet the gas supply demand of the target ash silo 10 based on the current material level data of the target ash silo 10. Then, based on the recommended number of operating fans and the current number of operating fans, the valve opening data of the target gas regulating valve 20 is determined, and the target gas regulating valve 20 is controlled to operate according to the valve opening data. In this way, the gas supply can be flexibly adjusted according to the needs of different target ash silos 10, ensuring that each target ash silo 10 receives an appropriate amount of gas, thus meeting the gas supply demand of the target ash silo 10 while avoiding the waste of gas supply resources due to excessive gas supply from the target fan assembly 30.

[0055] Optionally, at least three target ash silos 10 include an original ash silo 101, a coarse ash silo 102, and a fine ash silo 103. The target gas regulating valve 20 includes at least a first gas regulating valve 201 on the ash silo branch pipe 11 connected to the original ash silo 101, a second gas regulating valve 202 on the ash silo branch pipe 11 connected to the coarse ash silo 102, and a third gas regulating valve 203 on the ash silo branch pipe 11 connected to the fine ash silo 103. The current material level data includes at least the first material level data of the original ash silo 101, the second material level data of the coarse ash silo 102, and the third material level data of the fine ash silo 103. In step S12, the recommended number of operating fans for the target fan assembly 30 is determined based on the current material level data, including: determining the recommended number of operating fans based on the first material level data, the second material level data, and the third material level data.

[0056] In some implementations, a recommended number of operating fans corresponding to multiple gas supply demand intervals can be preset. Thus, the total gas supply demand of at least three target ash silos 10 can be determined based on the first, second, and third material level data, and the target gas supply demand intervals corresponding to the total gas supply demand of at least three target ash silos 10 can be determined from the multiple gas supply demand intervals. This further determines the recommended number of operating fans corresponding to the target gas supply demand intervals, i.e., the recommended number of operating fans for the target fan assembly 30.

[0057] In other embodiments, determining the recommended number of operating fans based on the first material level data, the second material level data, and the third material level data includes: determining the sum of the first material level data, the second material level data, and the third material level data to obtain total material level data; in response to the total material level data being less than a preset threshold, determining the recommended number of operating fans as the first number; or, in response to the total material level data being greater than or equal to the preset threshold, determining the recommended number of operating fans as the second number, wherein the second number is greater than the first number.

[0058] For example, the first number of units may include 1 or 2 units; the second number of units may include 2 or 3 units. When the first number of units is 1, the second number of units is 2 or 3; when the first number of units is 2, the second number of units is 3. This disclosure will be further explained using the example of the first number of units being 2 and the second number of units being 3.

[0059] It should be noted that this disclosure does not limit the preset threshold, which usually depends on the user's needs. For example, the preset threshold can be determined based on the intermediate material level data of the target ash silo 10, where the intermediate material level data of the target ash silo 10 is used to characterize that the current ash level data in the target ash silo 10 is at an intermediate value. That is, when the material level data of the target ash silo 10 is greater than or equal to the intermediate material level data, it indicates that there is a lot of ash in the current target ash silo 10; when the material level data of the target ash silo 10 is lower than the intermediate material level data, it indicates that there is a little ash in the current target ash silo 10. Furthermore, the intermediate material level data of the target ash silo 10 can be 5 meters, 6 meters, 8 meters, etc. Taking the intermediate material level data of the target ash silo 10 as 5 meters as an example, the preset threshold is 15 (3×5=15) meters.

[0060] Therefore, when the total material level data is less than 15 meters, it indicates that the total material level data is less than the preset threshold, that is, the total material level data of the target ash silo 10 is lower than the total intermediate material level data. At this time, the ash content in the current target ash silo 10 is relatively low, so the recommended number of operating fans can be determined to be the first number, that is, 2 units. When the total material level data is greater than or equal to 15 meters, it indicates that the total material level data is greater than or equal to the preset threshold, that is, the total material level data of the target ash silo 10 is greater than or equal to the total intermediate material level data. At this time, the ash content in the current target ash silo 10 is relatively high, so the recommended number of operating fans can be determined to be the second number, that is, 3 units.

[0061] Optionally, the valve opening data of the target gas regulating valve 20 is determined based on the recommended number of operating fans and the current number of operating fans, including: determining a first correction coefficient and a second correction coefficient based on the recommended number of operating fans and the current number of operating fans; obtaining the first maximum material level of the original ash silo 101, the second maximum material level of the coarse ash silo 102, and the third maximum material level of the fine ash silo 103; determining the valve opening data of the first gas regulating valve 201 based on the first correction coefficient, the second correction coefficient, and the ratio of the first material level data to the first maximum material level; determining the valve opening data of the second gas regulating valve 202 based on the first correction coefficient, the second correction coefficient, and the ratio of the second material level data to the second maximum material level; and determining the valve opening data of the third gas regulating valve 203 based on the first correction coefficient, the second correction coefficient, and the ratio of the third material level data to the third maximum material level.

[0062] The first and second correction coefficients are parameters used to adjust the valve opening data in the ash silo gasification air system. For example, the first correction coefficient is used to ensure that when the current gas supply flow rate is low based on the recommended number of operating fans, the calculated valve opening data is greater than the initial valve opening data. This prevents system pressure buildup due to an excessively low initial valve opening data, thus ensuring the safe operation of the ash silo gasification air system. The second correction coefficient is used to ensure that when the current gas supply flow rate is high based on the recommended number of operating fans, the calculated valve opening data is less than the initial valve opening data. This ensures a balanced system load and avoids efficiency reduction or equipment damage caused by excessive gas flow due to an excessively high initial valve opening data.

[0063] The first maximum material level is the theoretical maximum material level of the original ash silo 101; the second maximum material level is the theoretical maximum material level of the coarse ash silo 102; and the third maximum material level is the theoretical maximum material level of the fine ash silo 103.

[0064] For example, the ratio of the material level data to the maximum material level indicates the usage within the target ash silo 10, i.e., the filling degree of the target ash silo 10. A higher ratio indicates a higher filling degree of the target ash silo 10, meaning there is more ash in the target ash silo 10. In this case, it is necessary to increase the gas flow rate by increasing the valve opening of the gas regulating valve to meet the gas supply requirements of the target ash silo 10. Conversely, a lower ratio indicates a lower filling degree of the target ash silo 10, meaning there is less ash in the target ash silo 10. In this case, it is necessary to reduce the gas flow rate by decreasing the valve opening of the gas regulating valve to reduce unnecessary consumption of gas resources.

[0065] Therefore, the ratio of the material level data to the maximum material level can be combined with the first correction coefficient and the second correction coefficient to dynamically determine the valve opening data of the gas regulating valve according to the actual operating status, so as to optimize the operating efficiency and stability of the ash silo gasification air system and improve the resource utilization effect of the ash silo gasification air system.

[0066] Based on the above embodiments, the first correction factor and the second correction factor are determined according to the recommended number of operating wind turbines and the current number of operating wind turbines, including: determining the first correction factor and the second correction factor according to the following formula: ,

[0067] in, This is the first correction factor; This is the second correction factor; X is the current number of wind turbines in operation, where, ; To recommend the number of wind turbines to operate.

[0068] Optionally, the valve opening data of the first gas regulating valve 201 is determined based on the first correction coefficient, the second correction coefficient, and the ratio of the first material level data to the maximum value of the first material level; and the valve opening data of the second gas regulating valve 202 is determined based on the first correction coefficient, the second correction coefficient, and the ratio of the second material level data to the maximum value of the second material level; and the valve opening data of the third gas regulating valve 203 is determined based on the first correction coefficient, the second correction coefficient, and the ratio of the third material level data to the maximum value of the third material level, including: The valve opening data of the first gas regulating valve 201, the valve opening data of the second gas regulating valve 202, and the valve opening data of the third gas regulating valve 203 are determined according to the following formulas:

[0069] in, This refers to the valve opening data of the first gas regulating valve 201; This refers to the valve opening data of the second gas regulating valve 202; This refers to the valve opening data of the third gas regulating valve 203; This is the data for the first material level; This is the data for the second material level; This is the data for the third material level; This represents the maximum value of the first material level. This is the maximum value of the second material level; This is the maximum value of the third material level; This is the first correction factor; This is the second correction factor.

[0070] It should be noted that when the recommended number of operating fans is greater than the current number of operating fans (for example, the recommended number of operating fans is 3, and the current number of operating fans is 1), the flow rate of the gas supplied based on the current number of operating fans is relatively small. Therefore, the calculated valve opening data may be greater than 100%, which means that the valve is not fully open. Therefore, the upper limit of the valve opening data can be set to 100% to ensure the rationality of the valve opening data.

[0071] For example, a malfunction in the level sensor or a problem during data transmission may lead to abnormal level data. Therefore, the ash silo gasification ventilation system can also detect level data and, based on preset interlocking logic, automatically cut off the automatic control of the gas regulating valve when the level data is abnormal. In other words, the ash silo gasification ventilation system no longer relies on abnormal level data for automatic adjustment, thus avoiding erroneous operation. After cutting off the automatic control of the gas regulating valve, the ash silo gasification ventilation system will maintain the current opening state of the gas regulating valve to ensure the system continues to operate in a relatively stable state. Simultaneously, the ash silo gasification ventilation system can also issue alarm signals, such as audible or visual signals, to alert relevant personnel that an abnormality has occurred and manual intervention is required. The alarm signals aim to ensure that relevant personnel can take necessary operational measures in a timely manner, such as checking and repairing sensors, adjusting operating parameters, etc., to restore the ash silo gasification ventilation system to normal operation.

[0072] The above technical solutions enable flexible adjustment of gas supply according to the needs of different target ash silos 10, ensuring that each target ash silo 10 can receive an appropriate amount of gas. This not only meets the gas supply needs of the target ash silo 10 but also avoids the waste of gas supply resources caused by excessive gas supply to the target fan components.
