Abstract
Abstract Apparatus for the removal of liquid or solid particles from an aerosol flowing through a conduit. A feature of the method and means for this invention is the provision of (a) a deflector baffle member arranged to divert the flow of the gaseous stream of said aerosol from a wall of the conduit and to cause the stream to pass over a lip of the deflector member whereby an area of turbulence is formed downstream from the deflector member, and (b) a passage provided through the wall of the conduit adjacent said lip and downstream therefrom. It is a discovery of this invention that highly efficient particle separation is achieved by the formation of such turbulent area, or vortex, behind the lip wherein particles are momentarily trapped and then caused to move through the passage into a collection chamber.

Claim 1
Independent Claim
222 words
Means for separating particles from a moving aerosol wherein particles are suspended in a gaseous fluid stream, said means comprising: a. A centrifugal separator device having a circular cross section; b. A conduit for the gaseous stream, said conduit being within said centrifugal separator device and said conduit including an outer wall having an imperforate portion with a circular configuration; c. A chamber adjacent said conduit; d. A passage connecting said conduit with said chamber; e. A tangential inlet upstream of said passage, said inlet being alligned to conduct said gaseous stream tangentially into contact with said imperforate wall portion of said circular conduit; f. Flow deflecting means in said conduit adjacent to and extending downstream from said imperforate wall portion to contact said gaseous flow, said deflecting means including a baffle member disposed inwardly away from said outer wall into the conduit and said baffle member further being located adjacent to and up-stream of the mouth of said passage to divert said gaseous stream away from said imperforate wall portion and over said passage to cause a trailing vortex downstream of a lip of the baffle member thereby (i) to cause suspended particles to be trapped in said vortex and (ii) to cause said particles to be conveyed through said passage into said chamber and a gas outlet from the conduit.

Claim 3
Dependent Claim
81 words
The means of claim 1 in which said flow deflecting means comprises a baffle member, One edge of said baffle member being connected to said wall so that at the line of connection one side of said baffle member is mergent with the inside of said conduit wall, and said baffle being curved away from the curve of said wall so that the lip of said baffle is spaced from the projected arcuate plane of the inner side of said wall.
Claim 4
Dependent Claim
22 words
The means of claim 1 in which said chamber is closed and said chamber is connected to a pressure retaining discharge valve.
Claim 5
Dependent Claim
28 words
The means of claim 1 together with a curtain member disposed in said chamber adjacent to said passage and on the side thereof adjacent to said deflector lip.
