LIQUID-LIQUID PURIFICATION SYSTEM OF SAMPLE WITH ACOUSTIC DEPOSITION Russian patent published in 2019 - IPC B01D11/04 

FIELD: separation.

SUBSTANCE: group of inventions relates to purification of samples, particularly to liquid-liquid extraction. Proposed system comprises container assembly 12a to limit sample cleaning section 136a and having top end 56 and opposite bottom end 57. Sample cleaning section comprises mixing zones (31) and precipitation zones (33), first inlet opening (51a, 51c) and first outlet opening (51b, 51d) located on one of upper end and lower end of sample cleaning section, and second inlet (51c, 51a) and second outlet (51d, 51b) located on the other of the upper end and lower end of the sample cleaning section. First and second inlet holes and the first and the second outlet holes are in fluid communication with the sample cleaning section. Container comprises a plurality of screening elements (61) arranged inside the sample cleaning section to at least partially separate adjacent mixing zones (31) and deposition zones (33) or to separate adjacent mixing zones (31), wherein said mixing zones are communicated with sedimentation zones. In each of the mixing zones there is agent (78) for mixing the liquid. System comprises acoustic precipitation circuit (96, 97) having opposite ends in fluid communication with section (136a) for sample cleaning so that fluid sample can flow through acoustic precipitation circuit from sample cleaning section and return back to cleaning section sample; first acoustic wave precipitator (16d) aligned with the acoustic precipitation circuit, wherein the first acoustic wave depositor is configured to emit the acoustic wave on the fluid sample in the first acoustic precipitation circuit.

EFFECT: technical result is obtaining a high-purity sample in a relatively short period of time, simple method and design.
