Problems solved by technology

Most of the patents involve high-gravity rotating packed beds with similar structures, and they are all driven by a single motor. The high motor speed puts forward high requirements for assembly and debugging of the rotating shaft; most patents are applied to gas-liquid reactions, which are suitable for liquid-liquid mass transfer reactions.

Abstract

The invention relates to a dual-drive high-gravity rotating packed bed, and belongs to the technical field of chemical and metallurgical devices. The dual-drive high-gravity rotating packed bed comprises power transmission structures, liquid spraying structures, rotating shaft structures, a liquid mass transferring structure and a member fixing structure. According to a dual-motor drive, adjustable parameters of a reactor are increased, the primary-mixing mass transferring efficiency is improved through a nozzle with the solid cone, falling liquid drop can be newly thrown to a packed layer through a splashing disc and a lower rotating disc with a slant-face protrusion, motion trails of mixed liquid are jointly influenced by rotational flow and high gravity which are brought by edge pressing strips with right-angle bend corners, and the measures have the effects of prolonging the mixing time, enlarging the mass transferring area and improving the mass transferring efficiency.

Description

technical field [0001] The invention relates to a dual-drive high-gravity rotary packed bed, which belongs to the technical field of chemical and metallurgical equipment.
