Inventor: LANDOLT HANS
IPC: B01D45/08
Filed: 1981-03-11
Abstract: The interior of a housing, which has a gas inlet (4a) and a gas outlet (5a), is subdivided by parallel vertical baffle plates (1) into a number of chambers (2). Gas through-holes which are offset from each other and have funnel-like inserts (8), are provided in the successive baffle plates (1). The gas is thus repeatedly deflected on flowing through the separator and directed against the baffle plates (1), liquid droplets, which are suspended in the gas stream, impacting on the baffle plates (1) and remaining adhering to these. The liquid separated off runs downwards on the baffle plates (1) and through drain holes (9) in the bottom of the chambers (2) into a collection channel (10), from which it is discharged via a flow controller element (12) through a discharge pipe (11). The flow controller element (12) ensures that the pressure in the collector channel (10) is somewhat lower than in the chambers (2). Liquid droplets can be separated off by the separator from gas streams of all types, in particular oil droplets from a compressed air stream supplied from a compressor for paint spray guns or other sensitive applications. The oil can then be returned to the compressor through the discharge pipe (11). <IMAGE>
