DEVICE FOR CENTRIFUGAL PURIFICATION OF AEROHYDROFLOW Russian patent published in 2023 - IPC B01D45/12 B04C5/08 B04C5/12 

FIELD: filtering equipment.

SUBSTANCE: device for centrifugal cleaning of aerohydroflow includes a housing made of two mating parts with a tangentially mounted inlet pipe, an exhaust pipe installed inside the housing with a screw insert mounted around it, forming a conical screw channel with a shell with aspiration windows. The exhaust pipe is made of two parts: the lower, conical, mounted in the upper part of the body and made in the form of a confuser forming the inner surface of a conical screw channel with at least one recirculation window in its upper part, and the upper, cylindrical part made in the form of two pipes placed one inside the other - the internal and the external, forming a closed cavity between themselves. There is an ejection window at the bottom of the outer pipe that connects the closed cavity and the space of the first turn of the screw channel, and the recirculation window connects the closed cavity and the cavity of the conical part of the pipe.

EFFECTL: creation of a simple and reliable design that improves the quality of purification of aerohydroflow from impurities and particles.
