Abstract
An apparatus for removing particles from a fluid stream includes an unobstructed channel for conveying a stream in turbulent flow and a series of objects extending at least along one side of the channel, the objects being closely spaced from each other in the direction of flow so as to define therebetween spaces in which eddies penetrate from the channel to cause collection of particles on surfaces of the objects upon decay of the eddies.
Claims8
An apparatus for removing particles from a gas stream containing the particles which comprises a housing having an inlet and an outlet, a plurality of parallel straight flow passages arranged side-by-side for conveying said gas stream in a turbulent flow from said inlet to said outlet, said flow passages being vertically extending and being defined by a plurality of parallel vertically extending elements each of which is arranged adjacent to the turbulent flow in one of the plurality of flow passages, said elements having pleats arranged transversely to the turbulent flow, said pleats having vertically extending peaks joined to vertically extending valleys forming spaces therebetween which communicate with one flow passage in order to create a plurality of regions in which said particles are trapped and are deposited on surfaces of said pleats;
- said pleats being closely spaced together so that the spaces formed therebetween allow eddies of said gas stream to enter into outer portions of the spaces formed between said pleats and cause the eddies to decay in the regions located in inner portions of said spaces.
