Description
Technical Field
The invention belongs to the technical field of purification and separation equipment, and particularly relates to an ion exchange fiber device easy to fill.
Background
Ion Exchange Fiber (IEF) is a new fibrous Ion Exchange material developed on the basis of Ion Exchange resin, and is an Ion exchanger using fibrous material as skeleton, and most of Ion Exchange groups are present on the surface of fibrils. The working principle of the ion exchange fiber is the same as that of the ion exchange resin, and the ion exchange fiber selectively adsorbs required substances through the adsorption function of positive and negative ions and then is taken down by an eluant to achieve the functions of separation, extraction, purification, recovery and the like.
However, due to the difference of physicochemical properties of the two materials, the application effect is different, and the ion exchange fiber is more suitable in many application scenes. However, the application equipment of the ion exchange fiber material is relatively slow to develop relative to the ion exchange resin equipment and is not matched with the ion exchange resin equipment, so that the popularization and the use of the ion exchange fiber material are difficult. The main difficulties are: (1) the ion exchange fiber material is difficult to fill, and the equipment standardization and industrialization are difficult to realize; (2) the effective utilization rate of the ion exchange fiber material is low; (3) the exchange container is easy to block, and the running resistance is large; (4) the equipment has high operation pressure and high energy consumption; (5) the medicament consumption is large, and the treatment cost is high; (6) the equipment structure is complex, and the treatment process is difficult to control.
The structure of the prior art device is in the form of an exchange column, see fig. 1. The ion exchange fiber material 4 is filled in the exchange column 6, after the solution is pressed in from one end of the exchange column 6 through the pressure pump 7, the solution is contacted with the ion exchange fiber material 4 to complete the ion exchange process, and the solution comes out from the other end of the exchange column 6. The solution treatment process is continuous. The apparatus has the following problems: (1) the fiber material is difficult to comb due to the phenomena of curling and mutual winding of the fiber material, so that the integral filling density of the fiber column and the gaps of the fiber filaments are difficult to keep relatively uniform and consistent; (2) the liquid has larger resistance when passing through the fiber column, so the fiber filling height has requirements; (3) because the column shape of the ion exchange container is a closed pressure container, the fiber is cleaned and regenerated or the fiber material is replaced inconveniently.

Furthermore, the exchange container adopts a horizontal or vertical container.
Further, the stirring shaft adopts a single shaft, a double shaft or a multiple shaft.
Further, the number of the stirring blades is single, double or multiple.
Further, a gap is left between each stirring blade which winds and/or attaches the ion exchange fiber material.
Further, the driving device selects different motors according to different media.
Has the advantages that: the invention adopts a stirrer structure, so that the ion exchange fiber material is repeatedly contacted with the medium in the stirrer in a continuous rotating and stirring motion mode to complete the ion exchange process. The whole medium treatment process is intermittent, the ion exchange fiber material is easy to fill, the effective utilization rate of the ion exchange fiber material is high, the pressurization is not needed in the operation process, an exchange container is not easy to block, and the operation resistance is small; low energy consumption, low medicament consumption in the operation process and low operation cost.
