Description

Technical Field

[0001] The invention relates to the technical field of electrostatic precipitators, and in particular to a control system for dust expansion in a dust collector and a control method for dust expansion in a dust collector. Background Art

[0002] In the power, metallurgy and cement industries, the effective application of environmental protection equipment is the key to ensure that flue gas emissions meet environmental standards. Especially in these highly polluting industries, electrostatic precipitators and electric bag precipitators, as important dust removal equipment, play a vital role. These devices are mainly used to filter the flue gas generated during the combustion process to remove dust particles and harmful substances. The safe and efficient operation of dust removal equipment not only directly affects the production stability of the enterprise, but also determines the service life of the equipment. It is also one of the core links of environmental protection.

[0003] The working principle of the electrostatic precipitator is to charge the dust particles in the flue gas through a high-voltage electrostatic field, and use the electric field force to adsorb the charged dust particles to the dust collecting electrode. The dust is then shaken off the electrode surface by vibration or other cleaning methods and collected in the ash hopper. However, in actual operation, the ash hopper is prone to excessive dust accumulation and even clogging. Especially when the dust removal efficiency is high, the dust in the ash hopper increases rapidly. If it is not cleaned in time, the dust in the ash hopper may reach a full state, hindering further ash discharge operations.

[0004] In the prior art, the problem of ash accumulation and fullness in the ash hopper is one of the main causes of safety accidents in dust removal equipment. When the dust accumulation in the ash hopper exceeds a certain limit, the ash discharge port at the bottom of the ash hopper is easily blocked, and new dust cannot be discharged smoothly. This not only reduces the efficiency of the dust removal equipment, but may also cause damage to the equipment structure. In severe cases, it may even cause the equipment support structure to collapse due to overload. Most of the current solutions rely on manual regular inspection and cleaning of the ash hopper, but this method is inefficient and costly. Manual operation also has the limitation of relying on the operator's experience, which is prone to omissions or misoperation, and it is difficult to achieve real-time monitoring of the dust accumulation status of the ash hopper.

[0005] Therefore, the main problems of the existing technology include: 1) the ash hopper is easily blocked, resulting in reduced dust removal efficiency and posing a threat to equipment safety; 2) the existing manual cleaning method is time-consuming and labor-intensive, and cannot achieve real-time monitoring and rapid response; 3) the manual operation method has problems of human error and untimely cleaning, which affects the stability and safety of the dust removal equipment. In order to solve these problems, a system that can automatically monitor and control the ash storage in the ash hopper is urgently needed to improve the safety and operating efficiency of the dust removal equipment and reduce the safety hazards caused by ash hopper blockage. Summary of the invention

[0010] Optionally, the control device is configured to: simulate the increase in the ash storage amount per unit time of the corresponding ash hopper based on the real-time ash storage amount at each moment in the most recent preset period; if the real-time ash storage amount at the current moment is greater than the preset ash storage amount threshold, or the increase in the ash storage amount per unit time in the most recent preset period is greater than the preset increase amount threshold, then trigger the ionization generating device adjustment plan; execute the ionization generating device adjustment plan so that the ash storage amount at a predetermined moment in the future is not greater than the preset ash storage amount threshold.

[0011] Optionally, the rules of the adjustment plan for the ionization generating device are as follows: if the real-time ash storage amount at the current moment is greater than a preset ash storage amount threshold, the ionization generating device is controlled to increase power operation based on a preset power increase; if the ash storage amount increase per unit time in the most recent preset period is greater than a preset increase threshold, the power increase of the ionization generating device is determined based on the absolute value of the difference between the ash storage amount increase per unit time in the most recent preset period and the preset increase threshold, and the ionization generating device is controlled to increase power operation based on the power increase.

[0012] Optionally, the power growth of the ionization generating device is determined based on the absolute value of the difference between the increase per unit time of the ash storage amount in the most recent preset period and a preset growth threshold, including: collecting environmental information in the current ash hopper, and correcting a pre-trained power adjustment model based on the environmental information; using the absolute value of the difference between the increase per unit time of the ash storage amount in the most recent preset period and the preset growth threshold as an input parameter of the corrected power adjustment model to obtain the power growth of the ionization generating device.

[0013] Optionally, the environmental information includes humidity information, temperature information and air flow rate information; the pre-trained power adjustment model is corrected based on the environmental information, including: using the environmental information as a hyperparameter input of the pre-trained power adjustment model to initialize the model; performing a power pre-adjustment of the ionization generating device once within a predetermined period based on the initialized power adjustment model, and verifying the initialized power adjustment model based on the real-time ash storage amount after the pre-adjustment, and using the verified power adjustment model as the corrected power adjustment model.

[0014] A second aspect of the present invention provides a method for controlling the expansion of ash in a dust collector, and the method is implemented based on the above-mentioned control system for the expansion of ash in a dust collector, and the method includes: judging in real time the amount of ash stored in the corresponding ash hopper; adjusting the operating power of an ionization generating device based on the real-time amount of ash stored; wherein the ionization generating device is arranged on the inner wall of the ash hopper, and is used to generate ionization during the ash storage process to keep the ash stored in a fluffy state; and controlling the opening / closing of the ash hopper ash conveying valve based on the amount of ash stored in the ash hopper.

[0016] On the other hand, the present invention provides a computer-readable storage medium having instructions stored thereon, which, when executed on a computer, enables the computer to execute the above-mentioned method for controlling dust expansion in a dust collector.

[0017] Through the above technical scheme, the scheme of the present invention realizes real-time monitoring of the dust accumulation status in each ash hopper by setting an ash storage amount identification device at the bottom of the ash hopper, which helps to prevent excessive dust accumulation and blockage in the ash hopper. The ionization generator is arranged on the inner wall of the ash hopper, and releases ionization during the dust accumulation process to keep the dust fluffy, reduce dust agglomeration and compaction, and effectively reduce the risk of blockage.

[0024] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0025] Figure 1 This is a system structure diagram of a control system for dust storage expansion in a dust collector provided by an embodiment of the present invention. Figure 1As shown, an embodiment of the present invention provides a control system for ash expansion in a dust collector, the system comprising: an ash quantity identification device 20 disposed at the bottom of each ash hopper, for determining the ash quantity in the corresponding ash hopper in real time; at least one ionization generating device 10 disposed on the inner wall of the ash hopper, for generating ionization during the ash storage process to keep the ash in a fluffy state; a control device (not shown in the figure), which is communicatively connected with the ionization generating device 10 and the ash quantity identification device 20, and is used to adjust the operating power of the ionization generating device 10 based on the real-time ash quantity; an ash conveying device (not shown in the figure), which is connected to the control device, and is used to control the opening / closing of the ash conveying valve of the ash hopper based on the instructions issued by the control device.

[0026] In the embodiment of the present invention, the scheme of the present invention realizes real-time monitoring of the dust accumulation state in each ash hopper by setting an ash storage amount identification device 20 at the bottom of the ash hopper, which helps to prevent excessive dust accumulation and blockage in the ash hopper. The ionization generating device 10 is set on the inner wall of the ash hopper (preferably a negative ion generating device), and releases ionization during the dust accumulation process to keep the dust fluffy, reduce dust agglomeration and compaction, and effectively reduce the risk of blockage. The control device is connected to the ash storage amount identification device 20 and the ionization generating device 10 in communication, and can dynamically adjust the power of the ionization generating device 10 according to the real-time monitored ash storage amount to ensure that the dust is always in a controllable state. The design is further combined with the ash conveying device, and the ash conveying valve of the ash hopper is automatically controlled to open and close under the command of the control device, making the ash discharge process more intelligent and automated, reducing the frequency of manual intervention, improving the operating efficiency and safety of the dust removal equipment, reducing the risk of ash blockage, and extending the service life of the equipment.

[0027] Preferably, the ash storage amount identification device 20 comprises: a lever weighing module for identifying the real-time ash storage weight in the corresponding ash hopper; and a data transmission module for sending the real-time ash storage weight to the control device.

[0028] In an embodiment of the present invention, the lever weighing module adopts high-precision weighing technology, continuously senses the weight of dust in the ash hopper through the lever structure, and updates the weight data at a high frequency. The module can adapt to changes in different dust densities and accumulation rates, ensuring that the amount of dust accumulation in the ash hopper can be accurately identified under various operating conditions. The data transmission module is responsible for transmitting the real-time ash weight data obtained by the lever weighing module to the control device. Through real-time data transmission, the control device can dynamically grasp the dust status in the ash hopper, and combine other operating parameters (such as the shape of the ash hopper, the nature of the dust, etc.) to perform refined management of the entire dust removal system.

[0029] Based on the scheme of the present invention, the dust storage amount identification device 20 has the characteristics of high precision and real-time performance, and can effectively avoid the blockage problem caused by excessive dust in the ash hopper. At the same time, the lever weighing module provides a stable and accurate data source, and cooperates with the data transmission module to enable the system to adjust the opening and closing of the ash discharge valve and the power of the ionization generating device 10 in real time to ensure that the dust is fluffy and easy to discharge. This design greatly improves the automation of dust removal equipment, reduces the frequency of manual inspection and cleaning, improves production efficiency, and reduces equipment failure rate and operating costs.

[0030] Preferably, the operating voltage of the ionization generating device 10 is -30 kV to -100 kV.

[0031] In the embodiment of the present invention, the operating voltage range of the ionization generating device 10 is -30kV to -100kV, indicating that the device has a strong ionization release capability and is suitable for dust treatment in an efficient dust removal system. Within this voltage range, the ionization generating device 10 ionizes air molecules through high voltage to generate a large amount of ions. These ions combine with the dust particles in the ash hopper to give them a negative charge, and then through the electrostatic repulsion, the dust particles repel each other, thereby effectively avoiding the aggregation and agglomeration of the dust particles.

[0032] Inside the ash hopper, due to the high dust density and susceptibility to the influence of gravity, the dust particles will gradually compact under natural conditions, making it difficult to discharge the dust at the bottom of the ash hopper. If the dust is too compacted, it will not only affect the ash discharge efficiency, but also easily cause the ash hopper to be blocked. Through the high-voltage operation of the ionization generating device 10, ionization can cause the dust particles to remain fluffy and avoid the formation of a dense hard dust layer. In addition, the continuous action of ionization can significantly reduce the adhesion of dust, making it easier to detach from the ash hopper wall or other equipment surfaces, further improving the cleaning effect of the ash hopper.

[0033] Within the working voltage range, different voltage settings can adapt to different working conditions. When the amount of dust accumulated in the ash hopper is small, a lower voltage (such as -30kV) can be used to ensure a certain amount of ionization release and maintain the fluffiness and dispersion of the dust. When the dust in the ash hopper accumulates rapidly or the density is large, the voltage can be increased to a higher level (such as -100kV) to enhance the efficiency of ionization and ensure that the dust will not be compressed due to excessive accumulation. In addition, by real-time monitoring of the amount of ash stored in the ash hopper, the control system can dynamically adjust the working voltage of the ionization generator 10 according to actual needs to optimize the dust treatment effect.

[0034] Based on the scheme of the present invention, the ionization generating device 10 operates within a voltage range of -30kV to -100kV, providing strong support for the fluffiness of dust in the ash hopper, significantly reducing the risk of dust aggregation and compaction, thereby effectively solving the problem of ash hopper blockage. Ionization can not only reduce the adhesion between dust, but also prevent dust from adhering to the inner wall of the ash hopper, making it easier to remove dust and discharge it to the outside of the ash hopper. In addition, the dynamic adjustable voltage allows the system to flexibly control the amount of ionization generated according to actual operating conditions, optimize energy consumption and operating effects. This design improves the degree of automation of the dust removal system, reduces dependence on manual cleaning, extends the service life of the equipment, and reduces the failure rate of the equipment. By continuously keeping the dust loose, the equipment can operate stably under various working conditions, ensuring smooth ash discharge, and greatly improving the overall operating efficiency and safety of the dust removal equipment.

[0035] Preferably, the control device is configured to: simulate the increase in the ash storage amount per unit time of the corresponding ash hopper based on the real-time ash storage amount at each moment in the most recent preset period; if the real-time ash storage amount at the current moment is greater than the preset ash storage amount threshold, or the increase in the ash storage amount per unit time in the most recent preset period is greater than the preset increase amount threshold, then trigger the adjustment plan of the ionization generating device 10; execute the adjustment plan of the ionization generating device 10 so that the ash storage amount at a predetermined moment in the future is not greater than the preset ash storage amount threshold.

[0036] In the embodiment of the present invention, the unit time growth of dust accumulation in the ash hopper is calculated and simulated based on the real-time ash storage at each moment in the most recent preset cycle. The control device continuously monitors the ash storage at each moment to evaluate the growth trend of dust in different time periods. Once it is detected that the real-time ash storage at the current moment exceeds the preset ash storage threshold, or the unit time growth of dust in the most recent preset cycle exceeds the preset growth threshold, the system will immediately trigger the corresponding ionization generating device 10 adjustment plan.

[0037] During the execution of the adjustment plan, the operating voltage or operating frequency of the ionization generating device 10 can be dynamically adjusted according to the real-time monitoring data to ensure that the dust particles remain fluffy and prevent excessive accumulation or agglomeration of dust. The goal of this adjustment plan is to control the amount of dust stored in the ash hopper at future times so that it always remains below the preset threshold. In this way, the system can prevent the occurrence of ash hopper blockage or dust removal equipment overload problems in advance, avoiding safety hazards caused by rapid dust accumulation.

[0038] Based on the scheme of the present invention, the scheme of the present invention realizes the refined management of the dust removal equipment by real-time monitoring of the amount of ash stored in the ash hopper and its unit time growth rate. The control device can not only take immediate action when the dust accumulates too quickly or exceeds the threshold, but also control the dust accumulation at future times in advance by adjusting the operation of the ionization generator 10. In this way, the system can take timely measures before the dust accumulation reaches a dangerous level to ensure that the ash hopper always remains in a safe operating state. This design greatly improves the automation and intelligence level of dust removal equipment, reduces the need for manual intervention, extends the service life of the equipment, and reduces the risk of production interruptions and equipment damage caused by ash hopper blockage.

[0039] Preferably, the rules of the adjustment plan of the ionization generating device 10 are as follows: if the real-time ash storage amount at the current moment is greater than the preset ash storage amount threshold, the ionization generating device 10 is controlled to increase the power operation based on the preset power increase; if the ash storage amount increase per unit time in the most recent preset period is greater than the preset increase threshold, the power increase of the ionization generating device 10 is determined based on the absolute value of the difference between the ash storage amount increase per unit time in the most recent preset period and the preset increase threshold, and the ionization generating device 10 is controlled to increase the power operation based on the power increase.

[0040] Furthermore, the power growth of the ionization generating device 10 is determined based on the absolute value of the difference between the growth per unit time of the ash storage amount in the most recent preset period and the preset growth threshold, including: collecting environmental information in the current ash hopper, and correcting the pre-trained power adjustment model based on the environmental information; using the absolute value of the difference between the growth per unit time of the ash storage amount in the most recent preset period and the preset growth threshold as an input parameter of the corrected power adjustment model to obtain the power growth of the ionization generating device 10.

[0041] In an embodiment of the present invention, when the real-time ash storage amount at the current moment exceeds the preset ash storage amount threshold, the system will immediately control the ionization generating device 10 to increase the power operation based on the preset power growth amount. This can quickly respond to the situation of excessive dust accumulation, increase the amount of ionization release, and cause the dust particles to remain fluffy and prevent compaction, thereby reducing the risk of ash hopper blockage. If the unit time growth of dust accumulation exceeds the preset growth threshold in the most recent preset cycle, the system will determine the power growth of the ionization generating device 10 based on the absolute value of the difference between the unit time growth and the preset growth threshold. This adjustment method allows the system to flexibly adjust the power output according to the actual dust accumulation rate, avoiding energy waste caused by fixed power adjustment.

[0042] Furthermore, in a further optimized technical solution, the power growth of the ionization generating device 10 is not only based on the growth rate of dust accumulation, but also comprehensively considered in combination with the current environmental information in the ash hopper (such as temperature, humidity, air flow rate, etc.). The system first collects the current environmental data, and uses these data to correct the pre-trained power adjustment model to adapt the model to the current operating conditions. By taking environmental information into consideration, the system can adjust the power more accurately to ensure that the best dust removal effect can be maintained under different working conditions. In the revised power adjustment model, the system uses the absolute value of the difference between the unit time growth of the amount of ash stored in the most recent preset period and the preset growth threshold as an input parameter. The model can intelligently calculate the power growth of the ionization generating device 10 based on the size of the difference to ensure that the power increase matches the actual demand. This method avoids the inflexibility of the traditional fixed power mode and makes the power adjustment more refined and intelligent.

[0043] Furthermore, the solution of the present invention effectively improves the response speed and operating efficiency of the dust removal system by dynamically adjusting the power of the ionization generating device 10. When too much dust accumulates, the system can immediately increase the ionization release amount to ensure that the dust particles remain fluffy and reduce the possibility of ash hopper blockage. In addition, by introducing a power adjustment mechanism based on the difference, the system can flexibly adjust the power according to the actual speed of dust accumulation, avoiding energy waste and excessive adjustment in the fixed power mode.

[0044] Furthermore, the pre-trained power adjustment model is modified based on environmental information, so that the system can adapt to the dust removal needs under different environmental conditions, improving the adaptability and accuracy of the system. This dynamic power adjustment method based on the difference between the environment and the growth amount can achieve a more optimized dust removal effect under different working conditions, reduce the frequency of manual intervention, and improve the automation level of the equipment. Ultimately, this design greatly improves the operating efficiency of the dust removal equipment, reduces the equipment failure rate, extends the service life of the equipment, and effectively controls energy consumption.

[0045] Preferably, the environmental information includes humidity information, temperature information and air flow rate information; the pre-trained power adjustment model is corrected based on the environmental information, including: using the environmental information as a hyperparameter input of the pre-trained power adjustment model to initialize the model; performing a power pre-adjustment of the ionization generating device 10 once within a predetermined period based on the initialized power adjustment model, and verifying the initialized power adjustment model based on the real-time ash storage amount after the pre-adjustment, and using the verified power adjustment model as the corrected power adjustment model.

[0046] In the embodiment of the present invention, the collection of environmental information mainly includes humidity information, temperature information and air flow rate information. These environmental parameters play a vital role in the dust accumulation and discharge process, especially humidity and temperature, which directly affect the adhesion of dust and the aggregation speed of particles. The air flow rate affects the suspension state of dust in the air and its sedimentation speed into the ash hopper. By integrating these environmental information into the power adjustment model of the ionization generating device 10, it can more accurately adapt to the dust treatment requirements under different working conditions.

[0047] Furthermore, the system uses environmental information such as humidity, temperature, and air flow rate as hyperparameter inputs of the pre-trained power adjustment model to initialize the model. By setting these hyperparameters, the system can establish a power adjustment model that better matches the actual working conditions based on the current environmental conditions. This step ensures that the model takes into account the dynamic changes in the environment when adjusting the power, and no longer relies on preset parameters under a single condition. After the power adjustment model is initialized, the system will perform a power pre-adjustment of the ionization generating device 10 once within a predetermined period. During this process, the power of the ionization generating device 10 will be adjusted according to the initialized model settings to cope with the current dust accumulation state in the ash hopper. Through this pre-adjustment, the system can preliminarily verify the effectiveness of the model after the environmental information is input, and test the power adjustment effect.

[0048] Furthermore, during the pre-adjustment process, the system will monitor the amount of ash stored in the ash hopper in real time, and verify the initialized power adjustment model based on the change in the amount of ash stored. If the actual amount of ash stored after pre-adjustment can reach the set target, that is, the dust accumulation is controlled within the preset range, the system will consider that the initialized model has passed the verification. Otherwise, the system will continue to adjust the hyperparameters of the model until the expected effect is achieved. After the verification is passed, the power adjustment model will be formally revised to a model suitable for the current environment. The revised model will become the basis for future power adjustments to ensure that the ionization generator 10 can continue to optimize its operation under real-time conditions. This process enables the power output of the ionization generator 10 to keep pace with environmental changes, thereby maximizing the dust handling efficiency.

[0049] Based on the solution of the present invention, by introducing environmental information and using it as a hyperparameter input of the power adjustment model, the system can significantly improve the power adjustment accuracy of the ionization generating device 10. Factors such as humidity, temperature, and air velocity directly affect the physical properties of dust. Considering these environmental information can ensure that the power adjustment process is closer to the actual working conditions. At the same time, through the steps of pre-adjustment and model verification, the system can quickly adapt to environmental changes and avoid excessive or insufficient power output while ensuring dust control.

[0050] Furthermore, this power adjustment method based on dynamic correction of environmental information can effectively improve the fluffiness of dust, reduce the risk of dust compaction in the ash hopper, and thus prevent the ash hopper from clogging. This solution not only improves the automation level of dust removal equipment, but also greatly reduces the frequency of manual maintenance, extends the service life of the equipment, and ensures stable and efficient operation of dust removal equipment under different environmental conditions. Ultimately, this technology achieves high efficiency and low energy consumption operation of dust removal equipment, providing reliable protection for environmental protection needs in industrial production.

[0051] An embodiment of the present invention provides a method for controlling the expansion of ash in a dust collector, the method comprising: determining in real time the amount of ash stored in a corresponding ash hopper; adjusting the operating power of an ionization generating device 10 based on the real-time amount of ash stored; wherein the ionization generating device 10 is arranged on the inner wall of the ash hopper, and is used to generate ionization during the ash storage process so that the ash is kept in a fluffy state; and controlling the opening / closing of an ash conveying valve in the ash hopper based on the amount of ash stored in the ash hopper.

[0052] In one possible implementation, the initial state of the system is: the ash discharge valve is closed and the electric field is working normally. The amount of ash stored in the ash hopper is monitored in real time by a high-precision analysis device. The device can accurately sense the amount of ash stored in the ash hopper and related weight data, continuously record these data and transmit them to the control system. The control system analyzes the accumulation trend of dust in the ash hopper based on the monitoring data. If the amount of dust is close to the safety threshold, the system will automatically issue an alarm to indicate that the amount of ash stored in the ash hopper is too high. In this case, the control system will adjust the output power of the ionization generator to increase the dust dispersion and anti-blocking effect of the equipment to ensure that the dust will not be further compacted. Once the amount of ash stored in the ash hopper approaches or reaches the preset safety threshold, the system will keep the dust fluffy and automatically discharge the ash by adjusting the output power of the ionization generator. The system will also monitor according to the ash discharge efficiency. If the ash discharge process is smooth and effective, the system will continue to operate normally. If there are problems such as excessive ash, poor ash discharge, blockage or leakage during the ash discharge process, the system will automatically identify the cause of the ash discharge failure and perform the following operations through the control module:

[0053] 1) Adjust the power of the ionization device: Increase the power output of the ionization device to enhance the dust dispersion effect and prevent further blockage.

[0054] 2) Send out an alarm signal: If the dust removal operation still cannot proceed smoothly and the dust accumulation exceeds the safety threshold, the system will send out an alarm signal and directly alert the high-voltage power supply system and central control equipment through the signal transmission module.

[0055] If the ash discharge failure cannot be resolved, the system will take emergency measures to stop the operation of the electric field and trigger the emergency ash discharge device to ensure the safety of equipment and personnel.

[0056] Furthermore, the adjustment of the operating power of the ionization generating device 10 based on the real-time ash storage amount includes: simulating the increase in the ash storage amount per unit time of the corresponding ash hopper based on the real-time ash storage amount at each moment in the most recent preset period; if the real-time ash storage amount at the current moment is greater than the preset ash storage amount threshold, or the increase in the ash storage amount per unit time in the most recent preset period is greater than the preset increase amount threshold, then triggering the adjustment plan of the ionization generating device 10; executing the adjustment plan of the ionization generating device 10 so that the ash storage amount at a predetermined moment in the future is not greater than the preset ash storage amount threshold.
