Easily-filled ion exchange fiber device

Abstract

The invention discloses an ion exchange fiber device easy to fill. The ion exchange fiber device comprises a driving device, an exchange container, and a stirring shaft, stirring blades and an ion exchange fiber material which are positioned in the exchange container, the exchange container is provided with a hollow accommodating space, the stirring shaft is arranged in the exchange container, the stirring shaft is connected with a driving device arranged outside the exchange container through a transmission device, and the stirring shaft can be driven by the driving device to rotate and stir around the axis of the stirring shaft; the stirring blades are fixedly arranged on the stirring shaft; the ion exchange fiber material is wound and / or attached to the stirring blade, and the stirring blade is driven by the driving device to rotate and stir in the exchange container, so that the ion exchange fiber material is continuously and fully contacted with a medium in the exchange container. The stirrer structure is adopted, the ion exchange fiber material is in repeated contact with a medium in the stirrer in a continuous stirring motion mode, the ion exchange process is completed, the ion exchange fiber material is easy and simple to fill, and the effective utilization rate is high.

Description

technical field [0001] The invention belongs to the technical field of purification and separation equipment, and in particular relates to an easy-to-fill ion exchange fiber device. Background technique [0002] Ion exchange fiber (Ion Exchange Fiber, IEF for short) is a new fibrous ion exchange material developed on the basis of ion exchange resin. on the filament surface. The working principle of ion exchange fiber is the same as that of ion exchange resin. It selectively adsorbs the desired substance through the adsorption function of positive and negative ions, and then removes it with an eluent to achieve separation, extraction, purification, recovery and other functions. . [0003] However, due to the differences in the physicochemical properties of the two materials, the application effects are also different, and ion exchange fibers are more suitable in many application scenarios. However, due to the relatively slow and unsuitable development of the application eq...

AI Technical Summary

Problems solved by technology

The equipment has the following problems: (1) Due to the fiber material's own curling and intertwining phenomenon, it is difficult to comb, which makes it difficult to keep the overall packing density of the fiber column and the gap between the fiber filaments relatively uniform and consistent; (2) Due to the resistance of the liquid when passing through the fiber column Larger, the fiber filling height is required; (3) Since the cylindrical ion exchange vessel is a closed pressure vessel, it is troublesome to clean and regenerate the fiber or replace the fiber material
