US 4,129,624 A · Fluid mixer

Abstract

A fluid mixer providing improved fine mixing of a rough mixture of liquid and gas. The mixer includes a plurality of grooved annular plates defining an annular array of flow passages leading inwardly from a delivery space receiving the rough mixture to an inner central outlet space for discharging the fine mixture. The gas is introduced into the liquid to define the rough mixture in the form of an annular stream directed toward an inlet opening delivering the liquid to a mixing space. The rough mixture is delivered through a transfer space to the annular space about the fine mixer. The annular inlet space has a relatively large volume to provide a low flow rate therethrough to the fine mixer. Confronting grooves of the fine mixer plates may cross, and in the illustrated embodiment, the grooves of one face cross a plurality of grooves of the opposite face. The grooved plates may be arranged in aligned relationship or may be randomly disposed as desired.

Dependent claims

A fluid mixer comprising:

means for injecting into a liquid a fine stream of gas to provide a rough mixture;
means for conducting the liquid-gas rough mixture to an annular inlet space;
and
means defining a first annular array of chordal substantially rectilinear flow passages leading inwardly from said inlet space to a central outlet space, and a second annular array of chordal substantially rectilinear flow passages intersecting said first flow passages for causing the rough mixture flowed through said flow passages to be discharged into said central outlet space in intersecting streams whereby the rough mixture is further mixed therein to define a fine mixture of said liquid and gas for delivery from said outlet space.
