To ensure the efficient operation of dust explosion-related monitoring systems, the key lies in product selection and installation standards, stability of information collection and transmission, a closed-loop system for early warning information processing, as well as institutional and human resource support. Below, I have summarized specific measures for you:
1. Product selection and installation standards
Sensor selection: Based on the type of dust removal equipment and dust type, select appropriate sensors (such as differential pressure sensors, temperature sensors, steam flowmeters, etc.), and ensure that their accuracy and anti-interference properties comply with the “Data Access Specification for Safety Production Risk Monitoring and Early Warning of Dust Explosion-related Enterprises (Trial)”.
Installation method: The sensor should be installed at key locations, such as the inlet and outlet of dust removal equipment, material silos, flushing pipelines, etc., to prevent installation at locations that may be affected or vibrate.
Explosion-proof design: All equipment must comply with explosion-proof standards, and electrical equipment should obtain an explosion-proof certificate to ensure that non-explosion-proof electrical equipment is not used in areas with dust explosion hazards.
II. Stability of information collection and transmission
Data collection: Automatically collect key parameters such as the start-stop data signals of dust removal equipment, pressure difference between inlet and outlet, ambient temperature of the material silo, sprinkling water volume, and water level in the water tank, ensuring detailed data.
Data transmission: The industrial production IoT network is selected for data transmission to ensure stable transmission, low latency, and prevent content loss or delay.
Verification rules: Regularly check and verify the collected data, and promptly troubleshoot equipment and transmission issues in case of anomalies.
III. Closed loop of early warning information processing
Grade classification early warning information: The system software dynamically creates four levels of early warnings, namely red, orange, yellow, and blue, based on the risk evaluation index system, and pushes them to relevant industries and emergency management departments through telephone calls, service platform messages, and other forms.
Closed-loop control process: Upon receiving early warning information, the company must immediately verify the operating status of the equipment, properly address potential issues, and eliminate the alarm within the specified time, forming a closed loop of “detection-early warning information-handling-feedback”.
Conduct drills on time: Enterprises should regularly carry out emergency response drills for dust explosion accidents to enhance employees’ emergency handling capabilities and ensure the effective operation of the alarm system during specific incidents.
IV. Institutional and Human Resources Guarantee
Responsibility mechanism: The company shall establish a responsibility system for forecasting and early warning of safety production work, and determine the dust explosion prevention and safety production responsibilities of the person in charge, relevant responsible comrades, and dust operation personnel.
Training and learning: Conduct regular safety education training and assessments on employees regarding dust explosion prevention, enabling them to understand the risks on the job site and grasp preventive and emergency response measures.
Maintenance: Regularly inspect and maintain monitoring instruments to ensure their normal operation and prevent invalid testing caused by mechanical failures.
V. Technical Support and Optimization
System: Based on actual operational conditions, continuously optimize the role of the monitoring and early warning system to enhance its stability and the informational value of early warnings.
Product upgrade: Pay attention to the application of new technologies and new machines in the field, promptly upgrade the detection system to ensure that the system remains at the forefront of the industry.
Through the aforementioned measures, the efficient operation of the dust explosion-related monitoring system can be fully ensured, the safety management level of enterprises can be improved, and the occurrence of dust explosion accidents can be prevented.
