ABSTRACT:
A gaseous stream is freed of its particulate material in apparatus which includes a casing having an inlet opening, an outlet opening, and an impingement screen disposed across the inlet opening and comprising single or multiple, preferably staggered rows of impingement elements of V-shaped transverse profile positioned with the apex thereof facing the inlet opening. As the gaseous stream flows through the impingement screen, vortices are formed at the trailing edge of each element whereby droplets in the gaseous stream are entrained into the vortices, spin into a low pressure region which exists inside the open rear of the impingement element, and drain by gravity to collecting means. A series of radially extending vanes positioned downstream of the impingement screen impart swirl to the gaseous stream. A series of coaxial frustoconical rings are provided downstream of the vanes. Support means maintain the coaxial frustoconical rings in overlapping arrangement. The action of the vanes, of the coaxial rings and of the support means on the gaseous stream enhances particle removal.
