METHODS FOR CLEANING A ROTOR OF A CENTRIFUGAL SEPARATOR, AND GAS SEPARATION PLANTS HAVING SUCH CLEANABLE CENTRIFUGAL SEPARATORS

摘要

Method and arrangement for cleaning a rotor (16) of a centrifugal separator (12) in a gas separation plant having at least two centrifugal separators, coupled in parallel and functioning by counter-current or co-current separation. For the purpose of alternately cleaning rotors (16) of the centrifugal separators (12), agas outlet line (24) from the one separator is shut off and an air inlet (34) in its gas outlet (22) upstream of the shut-off in the outlet line (24) is opened, the air from the air inlet (34) being made to flow through the rotor in the separator that is to be cleaned by means of the pumping action of the centrifugal separator itself and possible suction force from a common fan (28) via the gas inlet (20) of the other, active centrifugal separator.
