摘要： The filtering plant has a plurality of porous, gas-permeable filter elements with at least one raw gas side and at least one clean gas side. The gas to be cleaned (raw gas) flows towards the raw gas side, and the clean gas side is connected with a clean gas passage. Into the clean gas passage and into the filter elements, pulse gas coming from a pressure vessel is introduced for periodically detaching dust adhering at the raw gas side. Via a gas-permeable passage, the pressure vessel is connected with a measuring chamber having a smaller volume than the pressure vessel. While pulse gas flows out of the pressure vessel into the clean gas passage and to the filter elements, the pressure difference .DELTA.p=p1-p2 is measured and monitored, where p1 is the static pressure in the measuring chamber, and p2 is the static pressure in the pressure vessel. Expediently, an alarm signal is activated when the maximum of the pressure difference falls below a predetermined minimum value.
