A unique and novel mixing device to effect an intense and rapid mixing of two fluids which is comprised of a venturi tube connected to the first fluid and a feed member disposed around the venturi tube through which the second fluid can flow. The feed member has one or more chambers which connect with the venturi tube through which the second fluid can be admixed with the first fluid. A baffle is positioned axially opposite the exit of the venturi tube to promote additional mixing.
Device for mixing two fluids provided with a venturi tube through which a first fluid can flow said venturi tube in the direction flow narrowing in a first part to a throat and then widening in a shorter second part, with a feed member for a second fluid disposed around said venturi tube and from said feed member one or more channels open into said venturi tube, through which said channels said second fluid can be added to said first fluid, and with a baffle placed axially opposite the mouth of said second part of said venturi tube, comprising,

The present invention is directed to a unique and novel device for mixing two fluids. The device is comprised of a venturi tube through which a first fluid can flow with a feed member disposed around the venturi tube through which a second fluid can flow.
The venturi tube, looking in the direction of the flow of the first liquid, narrows to a throat and then widens. The feed member which is disposed around the venturi tube has one or more channels which connect to the venturi tube through which the second fluid is admixed with the first fluid. A baffle is positioned axially opposite the exit of the venturi tube to promote additional mixing.
The term fluid as used herein will be in the first instance be understood to mean liquids, but the device of the present invention can be used to admix both liquids and gases.
The invention is elucidated by reference to the following drawings:
FIG. 1 is a view, partly in elevation, partly in axial section, of a mixing device according to the invention, along the line I--I in FIG. 2;
FIG. 2 is a horizontal section along the line II--II in FIG. 1, the left-hand half showing a section in the plane of the throat of the venturi tube, and the right-hand half a section in the plane passing through the centers of the feed channels for the second liquid;
Same parts have same reference numbers in all figures. The reference numbers indicate:
41: a cylindrical housing of corrosion-proof material (chrome-nickel steel);
42: an insert fixed in the housing 1, made of corrosion-proof and wear-resistant material (chrome-nickel-molybdenum steel);
