Abstract

A cone-shaped screening member for separating solids from a gaseous medium such as steam flowing through a pipe line. The cone shaped member has a plurality of spaced annular screen elements of increasing diameters disposed behind each other with the cross section of each screen element shaped substantially as an obtuse triangle. Particular features of the screening member are, PA0 (a) inclining the outer triangle side of the screen element at about the inclination angle of the cone, and PA0 (b) providing a discharge opening in the pipe line at about the base of the cone for removal of separated solids. This prevents settling and clogging of the gas passage canals and also prevents accumulation of settled solids in the pipe.
