AI Technical Summary
Existing flue gas ducts with particle interception mechanisms are prone to re-ignition of intercepted particles under fluctuating airflow or operational conditions, leading to secondary pollution or reduced interception efficiency.
Design a flue gas duct with a particle interception mechanism, including a flue gas duct, a particle interception mechanism, an ash collection trough, an isolation wall, and an ash discharge port. By combining the inclined bottom and the isolation wall, an airtight isolation structure is formed to prevent particles from being re-raised.
It effectively prevents the re-ignition of intercepted particles, improves interception efficiency, reduces the risk of secondary pollution, and ensures the stability of airflow and the reliability of system operation.
