AI Technical Summary
Traditional baghouse dust collectors suffer from uneven dust removal, high energy consumption, and filter bag damage. In particular, under high-pressure pulse jet cleaning, the bottom of the filter bag accumulates dust severely, resulting in high air leakage and short filter bag life.
The cyclone cleaning device of the low-pressure pulse jet bag filter uses a cyclone generator and a guide sleeve design to form a forced rotation diffusion path with arc blades and spiral guide grooves. Combined with pressure-resistant sealing gaskets and dynamic sealing components, it achieves efficient airflow rotation and sealing. It is equipped with an angle adjustment mechanism and condensate guide groove to adapt to changes in filter bag pressure difference.
It achieves complete removal of dust accumulation at the bottom of the filter bag, reduces system energy consumption and leakage rate, extends filter bag life, avoids condensate corrosion, and provides adaptive adjustment of cleaning intensity.
