DEVICE FOR CENTRIFUGAL PURIFICATION OF AIR AND FLUID FLOW Russian patent published in 2023 - IPC B01D45/12 B04C5/103 

FIELD: air and fluid flow treatment.

SUBSTANCE: invention relates to the treatment of air and fluid flow, gas, etc. from impurities and dust, in particular to devices for purifying air and fluid flow using centrifugal force, and can be used in the gas, gas production, oil, chemical, and other industries. A device for centrifugal cleaning of air and fluid flow includes a housing, an inlet pipe mounted tangentially to the housing, an exhaust pipe with a screw insert mounted around it, forming a conical screw channel with aspiration windows. The device body is made in the form of three parts: the upper – cylindrical part with a screw channel formed by the screw insert and the inner housing, the middle – conical part of the body and the lower – hopper, equipped with a guide manifold in the upper part. The device is equipped with an ascending air and fluid flow divider mounted in the cross section of the middle conical part of the body under the lower edge of the exhaust pipe. The diameter of the ascending air and fluid flow divider is made in a ratio to the diameter of the exhaust pipe from 1.0: 1.0 to 1.0: 1.8, and to the cross-sectional diameter of the conical part of the body, located in the same horizontal plane with the divider, in a ratio of 1.0: 2.0-3.0.

EFFECT: creation of a simple and reliable design, easy to maintain during operation, providing high-quality purification of the air and fluid flow from impurities, associated with limiting the possibility of aspirated particles entering the ascending air and fluid flow.
