ABSTRACT:
In a fabric filter dust collector of the type including a plurality of elongated tubular fabric filter elements with an inlet for gas and entrained solids, an outlet for filtered gas and an outlet for separated solids wherein the gas and entrained solids enter the dust collector, the gas passes through the fabric filters to the outlet of the collector and particulate material is collected on the surface of the tubular filter elements. A sonic horn cleaning system including sound generators or horns are positioned in the dust collector which when sounded transmit energy to the filter elements to remove the filter cake from the tubular filter elements. A system is provided for determining whether the horns are operating and includes a tube connected to the vent of the horn which tube passes through the casing wall to a remote location where a sound detecting device can be utilized to pick up sound waves transmitted through the tube from an operating horn. The failure detection system can be used in other applications where several sonic generators are used in a confined space to determine which generators are operating.
