Abstract

The invention relates to a column type extraction device for pipe bundle multi-channel phase-dispersing; a main shaft is arranged inside the column type extraction device; two or at least three hollow thin tubes in parallel to the main shaft are distributed on the outer circumference of the main shaft; one end of each hollow thin tube is provided with a straight tube, and the other end of the hollow thin tube is bent to form a flanged bend; the bending direction of the flanged bend is the remote direction of a mounting shaft; the main shaft is connected with an electric motor, and drives the hollow thin tubes to carry out motion at a same speed with the main shaft when the main shaft rotates. The column type extraction device disclosed by the invention solves the difficult problems that a water phase or an oil phase with relatively small volume is difficult to disperse completely in the conventional mechanical stirring manner when the volume ratio of the water phase to the oil phase in an extraction process is large; and the difficult problems that the water phase and the oil phase are difficult to clarify and separate in an extraction system and the like caused by easy emulsification are also solved when the flow-rate ratio of the water phase to the oil phase is large.
