Description

Technical Field

[0001] This invention relates to the field of intelligent control, and in particular to an intelligent control system for dust removal in ironworks environments. Background Technology

[0002] Pulse jet baghouse dust collectors are widely used in the steel and petrochemical industries. They utilize the filtration effect of fiber fabrics to filter dust-laden gas. When dust-laden gas enters the dust collector, dust adheres to the outer surface of the filter bags. After accumulating to a certain extent, the bag expands and shakes off the dust into the ash hopper through the pulse jet back-blowing action. The dust is then transported out through the conveying system, thus completing the purification of the gas.

[0003] Steel enterprises have numerous dust-generating points in their raw material, sintering, ironmaking, and steelmaking processes, all of which require pulse-jet baghouse dry dust collection and purification facilities. A single steel enterprise may have dozens (or even more) pulse-jet baghouse dust collectors, requiring significant manpower and resources for maintenance. Coupled with the increase in labor costs, the development of intelligent technology in the steel industry necessitates centralized control, efficient management, and more stable operation of dust collectors. This also enables early warning and prediction of system performance, provides key inspection targets for production inspections, saves maintenance and repair manpower, and optimizes the quantity and frequency of spare parts procurement.

[0004] There is currently no effective solution to the problem of incomplete functions and low level of intelligence in the control system for dust removal equipment in iron plants in related technologies.

[0033] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0034] like Figure 1 , Figure 3 As shown, this invention provides an intelligent dust control system for ironworks environments. This system includes: a fault inspection unit 4, an identification and prompting unit 5, a system analysis unit 6, a data storage unit 1, a fault troubleshooting unit 2, and a fault alarm unit 3, wherein:

[0035] The fault inspection unit 4 is used to detect the fault location of the dust removal equipment 9 and output fault information;

[0036] The identification and prompting unit 5 is used to identify preset alarm information and output the alarm information;

[0037] The system analysis unit 6 is used to determine the failure time and / or usage cycle of each component in the dust removal equipment 9, and to output alarm information in advance;

[0038] Data storage unit 1, the signal receiving end of data storage unit 1 is connected to the signal output end of fault inspection unit 4, the signal output end of identification prompt unit 5 and the signal output end of system analysis unit 6 respectively. Data storage unit 1 is used to pre-store the data information of dust removal equipment 9 and to receive fault information, alarm information and alarm information.

[0039] The fault troubleshooting unit 2 is connected to the signal output terminal of the data storage unit 1. The fault troubleshooting unit 2 is used to retrieve a pre-set solution based on the fault information, alarm information, alarm information and the data information pre-stored in the data storage unit 1.

[0040] The fault alarm unit 3 is connected to the signal output terminal of the data storage unit 1. The fault alarm unit 3 is used to send a preset alarm signal based on the fault information, alarm information, alarm information and the data information stored in the data storage unit 1.

[0041] This invention utilizes a fault inspection unit 4, an identification and prompting unit 5, a system analysis unit 6, a data storage unit 1, a fault troubleshooting unit 2, and a fault alarm unit 3 in conjunction to achieve centralized control of dust removal equipment in ironworks. This saves management costs, improves control efficiency, and enhances the system's intelligent management capabilities through intelligent control. It effectively reduces the burden of controlling dust removal equipment, saves control costs and energy consumption, and improves economic benefits. Furthermore, it enriches the fault detection and alarm functions of dust removal equipment, increases the ability to provide early warnings of faults, and reduces safety risks.

[0042] In an optional embodiment of the present invention, such as Figure 1 As shown, the intelligent dust control system for the ironworks environment also includes an interlocking operation unit 7, which pre-sets the first and second functional devices in the dust removal equipment 9 to operate in an interlocking manner according to the dust removal requirements.

[0043] Furthermore, the first functional component can be a dust removal fan, and the second functional component can be a dust removal valve on the dust removal equipment 9. When the dust removal fan is operating, the dust removal valve is controlled to operate in an interlocking manner. To avoid wasting airflow, for inactive dust removal equipment 9, the dust removal valve and other valves interlocked with it (i.e., valves whose opening or closing status does not affect the normally operating dust removal equipment 9) must be closed promptly. Some manual valves can be prompted by system voice or signals to ensure efficient valve utilization. To save energy, the dust removal fan in the dust removal equipment 9 is interlocked with the corresponding dust removal valve. Of course, the first and second functional components can also be other functional components in the dust removal equipment 9, such as interlocking the dust removal valve in the dust removal equipment 9 with the production equipment. For example, to prevent excessive emissions of pollutants in the flue gas, the dust removal fan can be interlocked with the dust emission concentration detection element. When an emission alarm (exceeding the standard) is triggered, the dust removal fan speed is reduced, and a fault inspection program can be quickly initiated simultaneously to check for equipment malfunctions. In this invention, no specific functional element is limited to implement the interlocking operation; the interlocking relationship can be set according to the actual working conditions.

[0044] In an optional embodiment of the present invention, the data information stored in the data storage unit 1 (data twin) includes at least the three-dimensional model of the dust removal equipment 9, raw data, real-time operating data, and operation and maintenance data.

[0045] The 3D model should include at least the equipment, civil engineering, steel structure, pipelines, and instrumentation of the ironworks. The raw data should include at least the original parameters, attributes, drawings, documents, manuals, and instructions for the dust removal equipment 9. Real-time operational data should include at least the real-time data for each measuring point on the dust removal equipment 9, such as flow rate, temperature, pressure, fan speed, emission concentration, bearing vibration, bearing temperature, and noise. Maintenance data should include at least the time nodes and cycles for inspections, repairs, and parts replacements, as well as the frequency and location of fault alarms.

[0046] In this embodiment, the establishment of the 3D model and the collection of raw data can be completed during the design phase of the ironworks and the installation of the dust removal equipment 9. Real-time operating data can be collected and uploaded by the detection instruments set at the corresponding locations on site and stored in the data storage unit 1. Maintenance data can be uploaded by management personnel to the data storage unit 1, including information on maintenance personnel, maintenance time nodes, and types and models of maintenance equipment for each maintenance operation, enabling the accumulation and analysis of data under subsequent operating conditions.

[0047] In an optional embodiment of the present invention, the fault troubleshooting unit 2 pre-stores solutions for different fault locations and different fault types in the dust removal equipment 9. The fault troubleshooting unit 2 judges the fault location and fault type in the dust removal equipment 9 based on the fault information, alarm information, alarm information and data information pre-stored in the data storage unit 1, and retrieves the corresponding solution based on the fault location and fault type.

[0048] Specifically, the solutions pre-stored in the troubleshooting unit 2 can include, but are not limited to, troubleshooting methods for bag filters, dust discharge devices, filter bags, scraper conveyors, bucket elevators, pneumatic conveying devices, fan performance issues, fan mechanical issues, fan mechanical vibration and elimination methods, valve issues, etc. Of course, solutions can be pre-stored according to the actual fault conditions and corresponding solutions; this invention does not limit specific faults or corresponding solutions.

[0049] In an optional embodiment of the present invention, such as Figure 2 As shown, the signal output terminal of the fault troubleshooting unit 2 is connected to the signal receiving terminal of the fault alarm unit 3, so that the fault alarm unit 3 sends a corresponding alarm signal according to the fault location and fault type of the dust removal equipment 9.

[0050] Furthermore, the fault alarm unit 3 presets corresponding alarm thresholds based on different fault locations and types. It can collect operating data from the dust removal equipment 9 using detection instruments. If the operating data of the dust removal equipment 9 exceeds the corresponding alarm threshold, the fault alarm unit 3 sends a preset alarm signal. Alternatively, the fault alarm unit 3 can also send preset alarm signals based on fault information sent by the fault inspection unit 4, alarm information sent by the identification and prompting unit 5, and / or alarm information sent by the fault alarm unit itself. This achieves interlocking between fault alarms and fault emission solutions, providing a corresponding solution as quickly as possible after the system issues an alarm signal.

[0051] Specifically, the fault location and fault type may include, but are not limited to, alarms for motor temperature and vibration of the fan in dust removal equipment 9. The motor of the fan in dust removal equipment 9 is equipped with an instrument box, which contains instruments that can collect data such as motor temperature and vibration of the fan. Alarms for abnormal flue gas emission concentration in dust removal equipment 9 are also included. A flue gas emission concentration detection element is installed at the flue gas outlet of dust removal equipment 9 to detect the concentration of the discharged flue gas. When the flue gas concentration approaches the preset upper limit, the fan speed is reduced. Alarms for overload operation in dust removal equipment 9 are also included. Each hopper in dust removal equipment 9 is equipped with at least two level gauges to measure the highest and lowest material levels in the hoppers. When the material level in the hopper exceeds the highest material level, an audible and visual alarm is triggered to indicate that dust removal equipment 9 is overloaded and requires immediate action. Alarms for excessive negative pressure and overcurrent at the fan inlet of dust removal equipment 9 can control the fan to operate at a reduced frequency until the alarm is cleared.

[0052] In an optional embodiment of the present invention, the fault inspection unit 4 collects real-time operating data of the dust removal equipment 9 and compares the real-time operating data with the original data stored in the data storage unit 1 to determine the fault location of the dust removal equipment 9.

[0053] Specifically, the fault inspection unit 4 has at least the function of inspecting the faults of major equipment in the dust removal equipment 9, such as filter bags, lifting valves, pulse valves, ash discharge valves, and scraper conveyors. It utilizes detection methods such as compartment differential pressure, dust collector inlet and outlet differential pressure, exhaust stack concentration detection, lifting valve open / closed limit switches, air manifold inlet blowpipe pressure, motor current detection, and speed detection to perform fault inspections on corresponding components. By comparing the collected actual operating data with the raw data stored in the data storage unit 1, it can determine which component or compartment in the dust removal equipment 9 is malfunctioning and provide a prompt message.

[0054] In an optional embodiment of the present invention, alarm information is preset in the identification and prompting unit 5. Actual alarm information is collected by an image acquisition device, and after matching the actual alarm information with the preset alarm information, the corresponding alarm information is output externally. The preset alarm information may include, but is not limited to, alarms for unauthorized entry, fire alarms, alarms for structural deformation of corresponding components in the dust removal equipment 9, and / or alarms for valves not being opened or closed according to operating conditions.

[0055] In an optional embodiment of the present invention, the system analysis unit 6 determines the failure time and / or usage cycle of each component in the dust removal equipment 9 based on the original data, real-time operating data and maintenance data of the dust removal equipment 9.

[0056] Furthermore, the system analysis unit 6 has at least the functions of equipment operation analysis (life analysis), energy consumption analysis, pipeline ash accumulation analysis, and environmental protection analysis.

[0057] Specifically, since the data storage unit 1 pre-stores information such as the initial usage time and expected service life of each major component (e.g., filter bags, pulse valves, bearings, etc.) in the dust removal equipment 9, and based on the maintenance and repair data accumulated in the data storage unit 1 during the operation of the corresponding components, statistical analysis can be performed according to data such as maintenance frequency and maintenance time nodes. This allows for the determination of the possible failure time and / or service life of each component, and early warning information can be issued in advance to reduce operation and maintenance costs. During the production state of the dust removal equipment 9, data such as power consumption and gas consumption are recorded in real time. Energy consumption over a certain period (e.g., one year) is accumulated. When the next cycle begins operation, the data is compared in real time with the data of the previous cycle to promptly confirm energy consumption. This allows for the pre-formulation of adjustment plans to ensure that energy consumption remains within a controllable range.

[0058] Specifically, since the main problem with dust removal equipment 9 during operation is its tendency to accumulate dust, the diagnosis and analysis of dust accumulation in the pipelines is particularly important. By adding flow and velocity measuring instruments at locations prone to dust accumulation, when the dust removal equipment 9 is initially running at full speed (valve fully open), the total flow rate and the flow rate and velocity at each location prone to dust accumulation are recorded (as standard values). Measurements are taken every preset time period (e.g., once a month), ensuring that the dust removal equipment 9 is running at the standard air volume (valve fully open), and the flow rate and velocity at each location prone to dust accumulation are recorded. Then, the cross-sectional area is calculated using the flow rate and velocity to determine the degree of dust accumulation, thus allowing for early prediction of the dust accumulation situation.

[0059] In an optional embodiment of the present invention, such as Figure 1 As shown, the intelligent dust control system for the ironworks environment also includes a monitoring and management unit 8. The signal receiving end of the monitoring and management unit 8 is connected to the signal output ends of the fault inspection unit 4, the identification and prompting unit 5, the system analysis unit 6, the data storage unit 1, the fault troubleshooting unit 2, the fault alarm unit 3, and the interlocking operation unit 7. The signal output end of the monitoring and management unit 8 is connected to the control end of the dust removal equipment 9 to control the working status of the dust removal equipment 9.

[0060] Furthermore, the monitoring and management unit 8 includes at least a computer terminal, a centralized control screen terminal, and a mobile terminal. The collected data and stored raw data can be displayed, centrally managed, and processed through these terminals. Additionally, the mobile terminal allows for remote, dynamic, real-time display of the dust removal equipment 9 and the sending of control commands.

[0061] The features and advantages of the intelligent dust control system for ironworks environments of this invention are:

[0062] I. The intelligent dust control system for ironworks can centrally control and dispose of multiple dust removal devices, saving management costs and increasing management efficiency.

[0063] Second, the intelligent dust control system for ironworks environments can improve the level of intelligence and save energy.

[0064] Third, the intelligent dust control system for the ironworks environment has enriched the functions of fault inspection and fault alarm, and added early warning and prediction functions, effectively reducing safety risks.

[0065] The above description is merely an illustrative embodiment of the present invention and is not intended to limit the scope of the invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present invention should fall within the scope of protection of the present invention.
