RECYCLABLE FILTER FOR CLEANING GASES OF SOLID AEROSOLS Russian patent published in 2012 - IPC B01D46/10 

FIELD: process engineering.

SUBSTANCE: invention relates to environmental protection and may be used in nuclear engineering for air cleaning of radioactive dust, metallurgy, chemical and other industries. Proposed filter comprises barrel casing with inlet and outlet branch pipe, cylindrical open-top filtration device arranged inside said casing and aligned therewith, and impact mechanism fitted at casing top to allow reciprocation of mechanism striker. Filter is furnished with elastic diaphragm tightly jointed with the casing to make dusty and clean air chambers. Filtration device top is tightly jointed with diaphragm bottom side. Striker can tightly close the filtration device bottom in striking on diaphragm. Relationship between casing ID and filtration device ID and OD makes 1:(0.75÷0.85):(0.45÷0.49).

EFFECT: higher efficiency, lower costs.
