Method of managing the cleaning of a bag filter

摘要

The method involves acquiring a measurement of a pressure drop signal (DP) across a bag filter, and filtering the signal by digital or analog unit to obtain a filtered signal (DP *>). A measurement of the filtered signal corrected by a flow value is calculated using a savisky-golay algorithm. A declogging sequence is initiated, when DP is greater than DP3, a declogging is not initiated from tau minutes or DPc is greater than DP2, where the DP3 is chosen in a range of 1500-2500 Pascal, DP2 is chosen in a range of 1000-2000 Pascal, and tau is chosen in a range of 15-90 minutes.
