Abstract
Abstract Illustrated and described is an apparatus for the separation of liquid drops or particulate solids from a gas stream comprising a plurality of parallel separator plates, a flow passage being formed between every two separator plates, each separator plate having at least one wave crest disposed approximately in its center and two wave troughs disposed at its edge on the inlet side and the outlet side, respectively, and forming an inlet section and an outlet section, respectively, as well as impingement-wall sections formed between the wave crest and the wave troughs, a main phase-separator chamber open in a direction counter to the direction of the gas flow being formed externally on the wave crest. In accordance with the invention, high separation efficiency with low pressure drop or low energy loss is obtained by providing an inlet nozzle formed in the inlet section, the gas stream being directable by means of the inlet nozzle onto the region on the inlet side of the opposite impingement-wall section.
