KOCHETOV NOZZLE ELEMENT FOR DUST-GAS CLEANING APPARATUS Russian patent published in 2016 - IPC B01D47/06 

FIELD: instrument making.

SUBSTANCE: invention relates to wet dust separation and can be used in chemical, textile, food, light and other industries for purification of gases. This is achieved by fact that in nozzle member for dust and gas catching devices comprises casing and elements increasing contact area of flow with nozzle adapter element housing is made in form of at least three coaxial hemispherical surfaces connected to each other with clearance by fastener through axisymmetrically located spacers in form of rings. Elements increasing contact area of flow with nozzle, are made in form of corrugated elements, which surfaces at their forming surface, are equidistant to hemi-spherical surfaces of adapter element housing, wherein corrugated elements are arranged with gaps relative to hemispherical surfaces of adapter element housing. Adapter element hemispherical surfaces are made perforated.

EFFECT: higher process efficiency and reliability due to more extended surface of the packing.
