Simulation Studies on Protector of Pulse-jet Cleaning Filter Bag

Designed protector of pulse-jet cleaning filter bag for refraining from damages caused by airflow. It was shown that air spurt angles and intensity were different from each other from various jets in the simulated map of airflow station. Simulated calculation of airflow station and expecially studied the protector and raising height (L) of venturi. The results indicated that cleaning airflow was the primary airflow about 60%-70% which entered filter bag from outside of intubation by induction; Raising height (L) and inclined angle (α) of nozzle would cause bigger effect on induction airflow and height (H) of nozzle slight effect on induction airflow, the optimal raising height (L) was 40-55 mm.
