DEVICE FOR PREPARING MIXES AND SOLUTIONS Russian patent published in 2011 - IPC B01F5/06 

FIELD: process engineering.

SUBSTANCE: inventions relates to dispersers to be used in oil industry for preparation of gas-liquid mix, i.e. foam, emulsion or suspension of required dispersion. Proposed device comprises casing, processing element arranged on core moving in said casing, and/or in casing. Various shapes and dimensions of said processing elements may be used Casing may have variable section. It is possible to vary dispersion of prepared mix or solution preparation interval by moving the core, i.e. variation is possible at constant flow rate. On the other hand, to allow constant dispersion of mix or constant rate/time of solution preparation at variable flow rates it is necessary and sufficiently to keep up constant pressure difference in said device by moving said core. If required, proposed device may be cut off without interrupting feed of mixed components.

EFFECT: possibility to vary dispersion and control rate/time of dissolution without varying flow rate.
