Abstract
A filtering separator for cleaning dust and smoke-particle-laden gases comprising a separator, a duct connected to the gas inlet of the separator and containing dust collector bodies around which the dirty gas flows, means for detaching particles which collect on and between said bodies, said detaching means affording at least intermittent application of vibration force, and means for feeding at least some of said particles to said separator along with the dirty gas.
Claims4
In a filter assembly comprising a housing having a perforated wall separating a dirty gas chamber with a raw gas inlet at the end of a raw gas duct and a clean gas chamber with a clean gas outlet, said dirty gas chamber containing filter elements exposed to the stream of raw inlet gases and adapted to be cleaned periodically by counter-current scavenging from the clean gas side, the improvement that there is interposed in the raw gas duct, upstream of the filter elements, at least one perforated drum containing individual dust collector bodies forming a dust collector in the path of the raw gas, and motion imparting means enabling the bodies in said drum to be placed in motion to cause said bodies to move about and rub against one another to free dust agglomerations thereon to be fed into the raw gas stream moving to the filter elements.
