Abstract
An arrangement for cleaning gas includes a centrifugal separator and pre-separation unit. The centrifugal separator includes a stationary casing, enclosing a separation space through which a gas flow is permitted, a gas inlet extending through the stationary casing and permitting supply of the gas from the pre-separation unit, a rotating stack of separation disks, a gas outlet and a drainage outlet for discharging separated liquid impurities. The pre-separation unit is arranged upstream of said inlet of said centrifugal separator, and it comprises a pre-separation inlet having a cross-sectional area A2 and permitting supply of the gas to be cleaned. A2 is larger than the cross-sectional area A1 of the inlet to the separation space of the centrifugal separator. A pre-separation outlet permits supply of gas from the pre-separation unit to the gas inlet of the centrifugal separator. A first chamber and a second chamber arranged downstream thereof are separated by at least one intermediate wall including at least one through-hole.
