Abstract

Abstract Apparatus for removing suspended matter from gases including a transverse baffle plate having openings for the passage of gases and separating units in said openings including a central pipe through which the gases pass and having vanes to cause rotation of the gas stream for the centrifugal separation of the suspended matter. A cap registers with said pipe having a central opening through which cleaned gases pass and has a deflecting annular rim with a depending skirt for deflecting the gases with a reversal in direction around the outside of said pipe to remove suspended matter by impingement.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 204 words
Apparatus for removing suspended matter from gases comprising a vessel having a transverse baffle plate extending thereacross to form separate input and output zones in said vessel and having openings for the passage of gases between said zones, and separating units disposed in registration with said openings, each such unit comprising a central pipe through which said gas stream passes into said outlet zone, means in said pipe to cause rotation of said gas stream for concentrating said suspended matter centrifugally in the peripheral portion of said stream, a cap disposed above the discharge end of said pipe and having an annular concave surface adapted to deflect the outer peripheral portion of said stream downwardly in a reverse direction around the outer surface of said pipe while retaining their rotation and having a downwardly extending skirt spaced beyond said pipe to form an annular passage for said gases and terminating above said baffle plate to provide an annular discharge opening for said gases to be further deflected by said plate into said output zone, said cap having a central opening through which the central portion of said gas stream passes directly into said output zone, and spray means disposed in advance of said plate.
Claim 2
Dependent Claim 204 words
Apparatus for removing suspended matter from gases comprising a vessel having a transverse baffle plate extending thereacross to form separate input and output zones in said vessel and having openings for the passage of gases between said zones, and separating units disposed in registration with said openings, each such unit comprising a central pipe through which said gas stream passes into said outlet zone, means in said pipe to cause rotation of said gas stream for concentrating said suspended matter centrifugally in the peripheral portion of said stream, a cap disposed above the discharge end of said pipe and having an annular concave surface adapted to deflect the outer peripheral portion of said stream downwardly in a reverse direction around the outer surface of said pipe while retaining their rotation and having a downwardly extending skirt spaced beyond said pipe to form an annular passage for said gases and terminating above said baffle plate to provide an annular discharge opening for said gases to be further deflected by said plate into said output zone, said cap having a central opening through which the central portion of said gas stream passes directly into said output zone, and spray means disposed in advance of said plate.
Claim 3
Dependent Claim 34 words
Apparatus as set forth in claim 1 including means in said annular passage for opposing rotation of said gas stream whereby said gases are caused to impinge on said baffle plate without substantial rotation.
Claim 4
Dependent Claim 23 words
Apparatus according to claim 1 in which said cap includes in its central opening means for opposing rotation of the gases passing therethrough.
Claim 5
Dependent Claim 26 words
Apparatus according to claim 1 wherein said spray means is directed to supply wash liquid to the units for preventing accumulation of separated suspended matter thereon.
