CYCLONIC FILTER Russian patent published in 2005 - IPC

FIELD: equipment for cleaning dust-laden gases in chemical, food and metallurgical industries.

SUBSTANCE: filter includes vertical cylindrical body with conical bottom provided with connecting means for dust removal, connecting means for feeding dust-laden gas into filter, lid, an exhaust pipe and connection means for cleaned gas extraction. Connection means for dust-laden gas feeding is tangential to the body. The exhaust pipe also serves as a filter. Connection means for cleaned gas extraction is composite and partly formed of porous material. Attached to wind wheel are rods with blades rotating together with the wind wheel around a filtering member.

EFFECT: provision of continuous regeneration of filtering exhaust pipe surface, increased efficiency of duct-gas system separation due to increasing duct particle velocities, reduced size due to usage of working space for centrifugal gas cleaning and filtration, simplified production and operational reliability.
