ION EXCHANGE RESIN COLUMN
Document Type and Number:
Japanese Patent JP2015080749
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an ion exchange resin column in which upflow regeneration is performed and a lower part of a resin layer is prevented from being fluidized without creating a space due to shrinkage of an ion exchange resin even in the initial stage of the regeneration so that a perfect fixed bed can be formed.SOLUTION: A water-permeable mesh disk 10 is arranged on the upper side of a packed layer of an ion exchange resin 6 in an upflow regeneration type ion exchange resin column 1 in a column body 2 of which the packed layer of the ion exchange resin 6 is formed and downflow circulating water is deionized. A guide plate 13 is arranged in the mesh disk 10 so that the mesh disk 10 can be moved vertically while keeping a substantially horizontal state.
