Ion exchange resin pretreatment device and ion exchange resin pretreatment method

摘要

It provides a pretreatment device for an ion exchange resin that can reduce moisture content easily and economically. A stock solution tank storing a non-aqueous solvent, an ion exchange resin container containing an ion exchange resin, and a moisture removal device for removing moisture in the non-aqueous solvent, and at the same time, from the stock solution tank, the ion exchange resin container and the moisture removal device After passing the non-aqueous solvent in the order of, the non-aqueous solvent is passed through the water removal device and the ion exchange resin container in the order of the water removal device and the ion exchange resin container from the circulation supply pipe and the stock solution tank for returning the passed non-aqueous solvent to the stock solution tank, A pretreatment apparatus for an ion exchange resin, comprising: at least one liquid feed pipe selected from a circulating liquid feed pipe for conveying the non-aqueous solvent passed through to the stock solution tank.
