RECTIFICATION APPARATUS USING HEAT PUMP Russian patent published in 2010 - IPC B01D3/08 B01D3/32 

FIELD: technological processes.

SUBSTANCE: invention is related to apparatus for distillation and increase of concentration and further condensation and final increase of concentration of easily evaporated component, preferably aqueous mixture. Heat required for distillation and increase of concentration is sent via common heat-transmitting body (3). Heat is produced as a result of condensation of steam generated by distillation and increase of concentration, moreover, steam by means of compression with application of heat pump obtains increase of boiling temperature, which is required for condensation. Apparatus consists of two sections: section of distillation and increase of condensation or the first section (1) and section of condensation and final increase of concentration or the second section (2), besides sections are combined around common heat transmitting body (3), which forms separating wall. Each section is additionally limited by a horizontal partially cylindrical jacket (13) and end wall at each side. Every section is equipped with spraying rotor (4), adjusted for liquid injection from each side from lower part of horizontal partially cylindrical jacket (13) inside towards direction of common heat-transmitting body, besides axial liquid channel (5) provides for continuous passage of liquid through apparatus, passing along lower part.

EFFECT: apparatus may provide for distillation and increase of concentration without necessity to use traditional distillation and concentration column, which reduces capital investments.
