HYDROCYCLONE Russian patent published in 2010 - IPC B04C9/00 

FIELD: process engineering.

SUBSTANCE: invention relates to separation liquid inhomogeneous media by centrifugal forces and can be used in chemical and petroleum industries, as well as for oil-containing fluid separation. Hydrocyclone comprises housing with tangential inlet, outlet and sand branch pipes, flotation products collecting chamber, cylindrical barrel and vane swirler arranged aligned with discharge branch pipe in flotation chamber. Hollow cylinder communicated with flotation products collecting chamber adjoins aforesaid cylindrical barrel and is aligned with it. Cylinder side surface is perforated to form cylindrical screen with hole diametre decreasing from top to bottom from 10 to 0.01 mm. Cylinder inner chamber acts as flotation chamber. Lower tapered section of Hydrocyclone accommodates drop-shaped hollow insert secure on the pipe aligned with sand branch pipe. Baffle is arranged on sand branch pipe outlet and features truncated cone shape. Its inner thread mating that of pipe end. Said baffle extends from sand branch pipe to allow moving along said pipe.

EFFECT: higher efficiency.
