HIGH-SPEED CLEANING OF CENTRIFUGAL SEPARATOR Russian patent published in 2019 - IPC B04B5/12 

FIELD: technological processes.

SUBSTANCE: invention relates to a centrifugal separator for purifying gas containing contaminants, comprising a fixed housing enclosing a separation space through which a gas stream is passed, gas inlet passing through the fixed housing and allowing to supply the gas to be cleaned, the rotating element comprising a plurality of separating elements located in said separation space and arranged to rotate about the rotation axis (X), outlet for gas configured to discharge cleaned gas and having an outlet through a wall of the fixed housing, and a drain outlet configured to release liquid impurities separated from the gas to be cleaned, a drive member for rotating the rotating member. Centrifugal separator additionally comprises control unit, which is made with possibility to control drive for rotation of rotating element at first speed during separation phase and at a second speed which is higher than the first speed during the cleaning phase to eliminate clogging on or between said separation elements, wherein the cleaning phase is shorter in time than the separation phase.

EFFECT: higher quality of cleaning.
