Apparatus for separating material particles from gases

Abstract

An apparatus for separating particles from a gas flow is provided, comprising: is provided on the concave side of each crest, the serrations winning A plurality of corrugated separator plates arranged in spaced parallel relation to each other and defining wave-like flow channels between each other. The warped surfaces of the separator plates are generated in cross-section by at least three circular arcs connected continuously and with alternating directions of curvature. The radius of each of the three circular arcs is different, the radius of the arc representing the crest being the smallest. The arcs define at least one crest between two troughs, forming an intake section and an outlet-section, respectively of each separator plate. A first separating chamber is provided opening towards the gas flow on the convex side of the crest and is formed by a blade projecting from the downstream side of the crest toward its upstream side and running along the crest. A plurality of serrations running along underneath the crests arranged opposite to the separating chambers of the crest of the adjacent separator plate. The smaller radius of the second arc and the serrations together with the separating chamber provide a narrowing of the duct toward the crest to increase the speed of the fluid flow. A collision occurs between the main upstream gas flow and a continuous gas flow recoil from the first separating chamber, causing a stationary micro-turbulence in the vicinity of the serrations without a significant loss of energy and speed, whereby even the smallest particles are separated by the serrations. Two additional separating chambers of specific cross-sections are provided strategically on the downstream past the crest, each retaining material particles not caught previously.
