DEVICE FOR MULTIPHASE EXTRACTION PROCESSES Russian patent published in 2008 - IPC B01D11/04 

FIELD: technological processes.

SUBSTANCE: device includes two contact chambers in the form of vertical tubes and two sedimentation tanks in the form of horizontal tubes. Each sedimentation tank is connected by pipes to front part of one chamber and to back part of another chamber. Front part of each chamber is made of a tube with lesser diameter, which holds connection pipe of sediment tank, and features a diffuser. Entrance cross-section of connection pipe is less than front part cross-section. Exit part of each chamber is connected to a sedimentation tank end, and the sedimentation tank is placed between entrance and exit chamber parts in height. To perform adjoint processes of extraction/flushing/re-extraction the device includes third chamber and third sedimentation tank.

EFFECT: reduced extraction agent volume; increased holding time of refinement and extract phase flow in contact chambers and improved extraction efficiency.
