APPARATUS FOR REMOVING IMPURITIES FROM FLUID STREAM Russian patent published in 2018 - IPC B04B5/10 

FIELD: centrifuge.

SUBSTANCE: group of inventions relates to an apparatus and method for removing impurities from a fluid stream, for example a stream of a liquid such as water. Apparatus for separating materials suspended in a fluid stream comprises a support structure, a separator unit rotatably mounted on the support structure, a device for rotating the separator unit on the support structure, the separator unit having a longitudinal axis of rotation extending through a longitudinal tube arranged centrally within the separator unit. Longitudinal tube is connected or connectable to a pressurised source of fluid requiring separation, and the longitudinal tube has one or more openings for receiving fluid under pressure from the said source and one or more lateral openings for introducing the fluid into the separator unit. Separator unit comprises, in addition to the longitudinal tube, a centrifugal separation chamber for separating suspended material from the fluid stream, a collector for collecting either suspended material separated from the fluid stream or fluid from which at least some of the suspended material has been removed. Collector is arranged radially outside the separator and is associated with a centrifugal separation chamber. Separator unit, a first and a second branch pipe through which the fluid components to be separated can pass, wherein the suspended materials separated from the fluid stream can pass through the first branch pipe, and the fluid stream from which the suspended materials have been removed can pass through another branch pipe and a set of blades or nozzles, and means for guiding the fluid stream or discharging fluid from the separator through the blades or through nozzles to form a turbine that can drive the separator into rotation. Method for cleaning fluid or separating suspended materials from a fluid comprises passing fluid through an apparatus for separating materials suspended in the fluid stream.

EFFECT: technical result is an increase in the reliability and throughput of the apparatus, as well as simplification of its design.
