Core Focus · Systematic Knowledge Sharin
Drawing on Villo’s extensive project experience in industrial dust collection and explosion protection, Mr. Miao delivered a comprehensive presentation covering:
- Classification methods and typical structures of industrial dust collectors
- Understanding and matching key parameters such as airflow, negative pressure, and filtration velocity
- Mechanisms of dust explosions and zoning principles (Zone 20 / Zone 21)
- Integrated explosion protection strategies including venting, isolation, suppression, and resistance
- Case reviews and reminders on common design pitfalls
Standard-Based Practice · Precision Implementation
In response to the concerns of the TÜV SÜD audit team, Mr. Miao provided in-depth analysis of how international standards such as ATEX, IECEx, and ISO are applied in the design and product testing of industrial dust collection systems. He also shared best practices from typical projects in high-risk sectors like lithium battery and metalworking, including standardized FAT (Factory Acceptance Test) and SAT (Site Acceptance Test) processes.
During the Q&A, both parties engaged in in-depth discussions on practical challenges and standard implementation, including:
- How to determine whether the interior of dust collection equipment should be classified as Zone 20 or Zone 21
- Key design differences for dust collection systems in different zones
- How to regulate powder spraying rates to meet operational requirements
- Whether pipes or cables near flameless venting devices affect pressure relief efficiency
- Critical points for client acceptance inspections
