AI Technical Summary
Traditional baghouse dust collectors suffer from problems such as turbulent airflow, low energy utilization, structural defects, and insufficient intelligence during pulse backflushing, leading to shortened filter bag life, increased energy consumption, and dust leakage.
Employing a flow guiding device, a gradually expanding flow guide tube, and an intelligent control unit, the flow is stabilized by flow guide blades and a conical flow guide head, ensuring uniform airflow distribution and vertical entry into the bag. Combined with wear-resistant ceramic liners and a sealing door, it achieves precise dust removal and reduces wear. A differential pressure sensor enables on-demand backflushing.
It improves the uniformity of airflow distribution and dust removal efficiency, reduces energy consumption by 20%-40%, extends the filter bag life to 100,000 hours, reduces dust leakage and wear, and enhances the intelligence level of the equipment.
