Abstract
Abstract A method of and an apparatus for mixing fluids. A first fluid is introduced into a fluid zone defined by a cylindrical shell. A second fluid is introduced into a plurality of pipes passing through the fluid zone at a pressure lower than that of the first fluid. Each pipe has a small passageway through its wall through which the first fluid enters due to the pressure difference. The two fluids then mix during passage from the fluid zone within the pipes.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
116 words
Fluid mixing apparatus comprising a cylindrical shell having first and second ends; first and second closure plates attached to said first and second ends, respectively, for closing said ends to define a first fluid zone within said shell; means for introducing a first fluid into said first fluid zone; and a plurality of conduits passing through said first fluid zone and supported by said first and second closure plates, said plurality of conduits adapted to carry a second fluid therethrough, each conduit having a fluid passageway through its wall and within said first fluid zone to permit said first fluid to flow from said first fluid zone into said conduits to mix with said second fluid.
Claim 2
Dependent Claim
116 words
Fluid mixing apparatus comprising a cylindrical shell having first and second ends; first and second closure plates attached to said first and second ends, respectively, for closing said ends to define a first fluid zone within said shell; means for introducing a first fluid into said first fluid zone; and a plurality of conduits passing through said first fluid zone and supported by said first and second closure plates, said plurality of conduits adapted to carry a second fluid therethrough, each conduit having a fluid passageway through its wall and within said first fluid zone to permit said first fluid to flow from said first fluid zone into said conduits to mix with said second fluid.
Claim 3
Dependent Claim
93 words
Fluid mixing apparatus comprising means defining a first fluid zone; means for introducing a first fluid into said first fluid zone; and a plurality of discrete tubular conduits passing through said first fluid zone and distributed over the entire cross section of said first fluid zone, said tubular conduits adapted to carry a second fluid therethrough, each tubular conduit having a fluid passageway through its wall and within said fluid zone to permit said first fluid to flow from said first fluid zone into said tubular conduits to mix with said second fluid.
Claim 4
Dependent Claim
93 words
Fluid mixing apparatus comprising means defining a first fluid zone; means for introducing a first fluid into said first fluid zone; and a plurality of discrete tubular conduits passing through said first fluid zone and distributed over the entire cross section of said first fluid zone, said tubular conduits adapted to carry a second fluid therethrough, each tubular conduit having a fluid passageway through its wall and within said fluid zone to permit said first fluid to flow from said first fluid zone into said tubular conduits to mix with said second fluid.
Claim 5
Dependent Claim
27 words
Apparatus as claimed in claim 2 in which each tubular conduit has substantially the same internal diameter and in which the passageways are of substantially uniform diameter.
Claim 6
Dependent Claim
25 words
Apparatus as claimed in claim 2 in which each tubular conduit has a plurality of fluid passageways through its wall and within said fluid zone.
Claim 7
Dependent Claim
30 words
Fluid mixing apparatus as claimed in claim 2 in which the plurality of discrete tubular conduits are distributed substantially uniformly over the entire cross section of the first fluid zone.
