Abstract
The structure of a gas scrubber for large diameter conduits. It employs an axially located element that forms an annular venturi passage. This eliminates any tendency toward incomplete scrubbing of the gas stream.
Claims2
A carbon scrubber for removing carbon from a synthesis gas stream, comprising in combination
- a ring having a ring cylindrical inner surface the diameter of which is equal to the inside diameter of a conduit for said synthesis gas stream,
- said ring having an outside diameter sufficient for cooperating with coupling flanges on said conduit,
- a tear shaped plug coaxially located centrally of said ring for forming an annular venturi passage for said synthesis gas stream,
- a plurality of radial struts for supporting said plug in said ring,
- said struts being streamlined for minimizing flow disturbance in said gas stream,
- a pair of manifolds in said ring for supplying water for scrubbing said gas stream,
- a plenum centrally located in said plug,
- passages inside said struts for connecting one of said manifolds to said plenum,
- a first plurality of ports located peripherally on said plug and connected to said plenum for spraying water outward into the throat of said annular venturi passage,
- a passage from said plenum to the nose of said plug for keeping the front surfaces wet and clean, and
- a second plurality of ports located on the inside of said ring radially opposite said first ports and connected to the other of said pair of manifolds.

A carbon scrubber for removing carbon from a synthesis gas stream, comprising in combination
- a ring having a right cylindrical inner surface the diameter of which is equal to the inside diameter of a conduit for said synthesis gas stream,
- said ring having an outside diameter sufficient for cooperating with coupling flanges on said conduit,
- an annular plug having a streamlined cross sectional shape for forming both an annular and an axial venturi passage for said synthesis gas stream,
- a plurality of radial struts for supporting said plug coaxially in said ring,
- said struts being streamlined for minimizing flow disturbance in said gas stream,
- a pair of manifolds in said ring for supplying water for scrubbing said gas stream,
- an annular plenum centrally located in said plug annulus,
- passages inside said struts for connecting one of said manifolds to said annular plenum,
- a first plurality of ports comprising two sets of ports located peripherally on the inner and outer surfaces of said annular plug and both sets connected to said annular plenum for spraying water radially inward and outward into the throats of said venturi passages,
- a plurality of passages from said annular plenum to the leading edge of said annular plug for keeping the front annular surface wet and clean, and
- a second plurality of ports located on the inside of said ring radially opposite the outer set of said first ports and connected to the other of said pair of manifolds.
