Abstract

A filter device is proposed for cleaning gas entraining foreign bodies, including at least one filter unit having at least one filter surface on a raw gas side to which a raw gas stream containing foreign bodies can be supplied, wherein filtration aids can be supplied to the raw gas stream and/or the filter surface, and wherein filtration aids and/or foreign matter attached to the filter surface can be cleaned off. The filter device additionally includes a fluidized bed arrangement in which a carrier fluid stream can be generated such that cleaned-off filtration aids and/or foreign matter can be held at least in part as filtration aerosol in a surrounding of the filter unit and/or can re-attach to a filter surface.
