Abstract
A process and apparatus are disclosed for mechanically mixing two immiscible liquids and one or more other substances by creating in the upper portion of the apparatus a continuous dual-layer liquid film composed of upper and lower layers of immiscible liquids such as oil and water, into which film one or more substances in the gas, liquid, powder, or a combined phase are dispersed and the resulting dispersed mixture is further mixed and emulsified in the lower portion of the apparatus under the action of shearing forces. A portion of the oil to be mixed may be fed directly into the lower portion of the apparatus for mixing with the pre-emulsified mixture.
Claims22
A continuous flow mixer comprising:
- tank means having two inlets for respectively receiving two immiscible liquids therein;
- means forming an inverted truncated conical surface coaxially disposed within said tank means, and having an upper circumferential rim communicating with the interior of said tank means and a lower open end sealed from the interior of said tank means;
- means for feeding two immiscible liquids into said tank means so as to overflow said rim and create a continuous downwardly flowing dual-layer liquid film on said conical surface from said rim to the open lower end;
- means for feeding a third substance into said tank means;
- means for centrifugally dispersing said third substance into said flowing liquid film on said conical surface;
- compartment means communicating with said lower open end for receiving the downwardly flowing dual-layer liquid film containing the third substance dispersed therein;
- and
- means in said compartment means for producing a shearing action on the liquids and third substance therein to mix and emulsify the two immiscible liquids and the third substance dispersed therein.
Apparatus for mechanically mixing two immiscible liquids and one or more other substances comprising:
- first and second coaxially disposed chambers, said first chamber having two inlets therein;
- means for feeding two immiscible liquids into said first chamber respectively through said two inlets;
- means for feeding a third substance into said first chamber;
- means, comprising a member containing a coaxially disposed inverted truncated conical surface having an upper circumferential rim communicating with said first chamber and a lower open end communicating with said second chamber, for conducting said two liquids, in the form of a continuous dual-layer liquid film flowing over the rim of the open upper end and downwardly over the inverted conical surface of said member, between said first and second chambers;
- first rotating means coaxially disposed within said member in the path of flow of said third substance for centrifugally dispersing said third substance into said liquid film;
- second rotating means coaxially disposed in said second chamber;
- and
- mixing means in said second chamber, including means for rotating with said second rotating means, for producing a shearing action on the liquids and third substance in said second chamber to mix and emulsify the two immiscible liquids and the third substance dispersed therein.
A process for mechanically mixing two immiscible liquids and one or more other substances comprising the steps of:
- feeding two immiscible liquids into a first chamber containing an inverted truncated conical surface having an upper circumferential rim communicating with the interior of said tank means and a lower open end sealed from the interior of said tank means;
- causing said immiscible liquids to flow over said conical surface rim for creating a continuous downwardly flowing dual-layer liquid film on said surface from said rim to the upper lower end;
- feeding a flow of a third substance into said first chamber and centrifugally dispersing said third substance into said downwardly flowing dual layer of liquid film;
- receiving the downwardly flowing dual-layer liquid film containing the third substance dispersed therein in a second chamber through the open end of said truncated conical surface;
- and
- producing a shearing action on the liquids and third substance in said second chamber to mix and emulsify the two immiscible liquids and the third substance dispersed therein.
