DYNAMIC AXIAL COMPRESSION SYSTEM Russian patent published in 2023 - IPC B01D15/10 B01D15/20 B01D15/22 

FIELD: dynamic axial compression system.

SUBSTANCE: invention is related to dynamic axial compression columns, in particular to a dynamic axial compression system. The system includes a tubular column body, a first pumping unit, an organic solvent storage tank and a filler collection tank, wherein the tubular column body is configured to accommodate the filler, and several holes for the filler are made in the lower part of the side wall of the tubular column body in the circumferential direction. Moreover, the inlet of the first pumping unit communicates with the organic solvent storage tank, and part of the holes for the filler communicates with the output of the first pumping unit. The other part of the holes for the filler communicates with the tank for collecting the filler. In addition, in the upper part of the side wall of the tubular body of the column there is an inlet for the filler, and on the pipeline connecting the inlet for the filler and the tank for collecting the filler, a second pump unit is additionally located, configured to pump the filler and organic solvent in the tubular body of the column into the tank for collecting filler; wherein the first pump unit and the second pump unit are located at the unloading station and are pneumatic diaphragm pumps.

EFFECT: development of a dynamic axial compression system, in which the efficiency of filler replacement is increased, which increases the productivity of liquid chromatography, further, the supporting structure is simplified, the weight of the equipment and maintenance time are reduced, which significantly increases the productivity of liquid chromatography.
