Abstract:
A method for separation of fine particles from a turbulent gas stream, comprising the steps of first agglomerating said fine particles in the form of larger particles by successively passing the gas stream through a series of filters in order to cause part of the particles to collide with solid parts of each filter so that part of the particles agglomerate and form larger particles, most of said larger particles being re-entrained in the gas stream, and then separating said larger particles by precipitation, wherein the step of separating said larger particles by precipitation comprises passing the gas stream having said larger particles reintrained therein from the series of filters through a precipitation device comprising at least one non-obstructed channel intended to convey the stream in a turbulent flow and a series of objects extending along at least one side of each channel, said objects being positioned at close intervals in the direction of flow so as to define with each other spaces which swirls coming from each channel enter, which leads to an accumulation of particles at the surface of said objects after the swirl have declined, wherein said objects consist of at least one corrugated plate.
