Operation Monitoring
During operation, it is recommended to inspect the bag filter every 30–60 minutes. Pay close attention to pressure, flow rate, and filtrate quality to prevent filter bag clogging or damage, which could cause filtration failure.

Key Parameter Monitoring Range

Parameter	Normal Range	Abnormal Condition
Inlet–Outlet Pressure Difference	≤ 0.1 MPa (adjusted according to filter bag precision)	Pressure difference > 0.15 MPa → Filter bag clogging
Flow Rate	Meets process design value	Flow rate decreases by >30% → Filter bag clogging
Filtrate Quality	Clear, no visible impurities	Filtrate becomes turbid → Filter bag damage or sealing leakage
Temperature	≤ Maximum temperature limit of filter bag (e.g., Polyester 130°C)	Temperature exceeds limit → Filter bag softening or damage
