EXHAUST PIPE OF DEVICE FOR CENTRIFUGAL TREATMENT OF AEROHYDROFLOW Russian patent published in 2023 - IPC B01D45/12 B04C5/12 

FIELD: gas purification.

SUBSTANCE: gas purification devices using centrifugal force that can be used in gas, gas production, oil, chemical and other industries. The exhaust pipe of the device for centrifugal treatment of the aerohydroflow includes a screw insert mounted around it, forming a conical screw channel, made in a shell housing with aspiration windows, and an inlet pipe tangentially mounted to the shell housing. The exhaust pipe is made of two parts: the lower conical part made in the form of a confuser 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 pipe and the external pipe - forming between them an enclosed cavity, while in the lower part of the outer pipe there is an ejection window, which 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.

EFFECT: creation of an exhaust pipe design that is easy to manufacture, which improves the quality of treatment of the aerohydroflow by moving the channels of the screw insert away from the center of the ascending flow and removing the particles remaining and floating in the cavity of the pipe for repeated cleaning.
