Abstract

See full text

The invention relates to a method for monitoring a compressed gas-based cleaning in a bag filter system (2). In order to achieve a cost-effective monitoring of a pressure-gas-based cleaning in a bag filter system (2), it is proposed that a flow (Q) of a compressed gas flow is determined during a cleaning process during a predefinable time period (T), using the determined flow rate (Q ) of the compressed gas flow, a flow characteristic (V) is determined and using the flow characteristic (V), the gas-based cleaning is monitored. Furthermore, the invention relates to a monitoring system (40) for a bag filter system (2), comprising at least one flow sensor (44) for determining a flow (Q) of a compressed gas flow and a control unit (42) for controlling a compressed gas-based cleaning, wherein the control unit (42) is set up to carry out the method. Furthermore, the invention relates to a bag filter system (2) with a plurality of bag filters (4) and such a monitoring system (40).
