1. Product Overview
The Dust Explosion Risk Monitoring and Early Warning System is an intelligent safety solution designed for industries exposed to combustible dust hazards.
It provides real-time monitoring and early warning of dust explosion risks by continuously supervising the operating status of dust collection systems and key safety parameters.
The system is built around a Smart Data Acquisition Station, independently developed by Hebei Shengnan Environmental Technology Co., Ltd., integrating sensors, data acquisition, wireless transmission, and risk analysis into one platform—without interfering with existing dust collection control systems.
2. Purpose and Safety Value
Combustible dust explosions are characterized by sudden occurrence, high destructiveness, and severe casualties, and are common in metal processing, woodworking, grain handling, and chemical industries.
This system helps to:
Monitor whether dust collection systems are operating properly
Detect abnormal operating conditions and reduced dust removal efficiency
Identify dust accumulation and ignition risks in advance
Prevent fire, deflagration, and explosion accidents
Support enterprise safety management and regulatory supervision
3. System Architecture
The system consists of three main components:
3.1 Sensor Subsystem
Collects key safety-related parameters
Newly installed sensors are electrically and logically isolated from existing systems
No impact on original dust collector control systems
3.2 Smart Data Acquisition Terminal
Independent data collection and processing
No reliance on existing PLCs or control systems
Suitable for old plants, unclear wiring, or missing sensors
3.3 Data Transmission & Warning Platform
Wireless data transmission via 4G cellular network
Real-time data analysis and risk assessment
Automatic alarm and notification upon abnormal conditions
4. Key Monitoring Points
1. Dust Collector Start/Stop Status
Acquired from control cabinet signals
Indicates whether the dust collection system is running
2. Inlet and Outlet Differential Pressure
Measured by differential pressure sensors
Reflects filter clogging, damage, or efficiency loss
3. Hopper Temperature Monitoring
Thermocouple sensors installed at dust accumulation zones
Detects abnormal heating, smoldering, or ignition risks
4. Rotary Valve / Discharge Device Status
Proximity sensors monitor continuous operation
Prevents dust buildup due to discharge failure
5. Operating Mode and Early Warning Mechanism
Sensors continuously collect safety-related data
Data is transmitted to the monitoring platform
The platform analyzes operating conditions and trends
Abnormal conditions trigger automatic alarms
Notifications are sent via platform messages or SMS
6. Typical Applications
The system is suitable for all industries with combustible dust risks, including:
Metal polishing and grinding workshops
Wood processing and furniture manufacturing
Grain, feed, and starch processing plants
Coal, carbon black, and metallurgical powders
Chemical and pharmaceutical powder handling
Textile, rubber, and plastic industries
