Abstract
Oil separation from discharge gas of a screw compressor is performed with a demister provided in a discharge chamber. For solving unevenness in the speed distribution of the gas in the chamber, at least one auxiliary demister for oil separation is disposed at a local position immediately behind or near the downstream side of an outlet of a discharge passage in a discharge casing so as to be perpendicular to the flow direction of the gas at the outlet. In addition, at least one obstacle plate is disposed on the downstream side of the auxiliary demister.
