DETECTION OF DEFECTS IN FILTER HOSES

In normal operation, a filter device (5) filters loaded waste gas (2) in filter groups (8) with filter sleeves (7). In a cleaning operation, a cleaning gas (12) is applied to a respective filter group (8) on the waste air side (10) via an associated valve (13) such that the filter cake (11) detaches...

Beschreibung
Zusammenfassung:	In normal operation, a filter device (5) filters loaded waste gas (2) in filter groups (8) with filter sleeves (7). In a cleaning operation, a cleaning gas (12) is applied to a respective filter group (8) on the waste air side (10) via an associated valve (13) such that the filter cake (11) detaches from the incoming air side (9) of the filter sleeves (7). A sensor device (16) arranged in the waste gas channel (6) detects a loading (B) of the waste gas (2) caused by the cleaning operation of each filter group (8). A monitoring device (17) records the generated loading (B) of the waste gas (2). It determines a respective state for every filter group (8), on the basis of the loading (B) caused by the cleaning operation of each filter group (8) in connection with the loading (B) caused by the cleaning operation of at least one other filter group (8).
