Abstract

The present invention relates to an electrodeionization filter comprising: a housing having a water inlet and a water outlet; a first electrode installed inside the housing in a spiral shape; a secondelectrode installed inside the housing in a spiral shape so as to be spaced apart from the first electrode; and an ion exchange module installed between the first electrode and the second electrode for adsorbing or desorbing ionic substances contained in water introduced by an application of electricity, wherein at least one of the first electrode and the second electrode has a structure in whichthe center portion thereof is denser than the peripheral region thereof. According to the present invention, the life span of the electrodes of the electrodeionization filter can be increased, and the assembly of the electrodes and related parts can be easily facilitated.

Description

technical field [0001] The present invention relates to an electrodeionization filter, and more particularly, to an electrodeionization filter configured to absorb and remove ionic substances contained in raw water using electric power. Background technique [0002] Recently, studies on electrodeionization filters for removing ionic substances and the like contained in raw water using electric attraction have been actively conducted. [0003] For example, Korean Patent Application No. 2015-0168858 filed by the present applicant proposes a technology involving the use of a bipolar ion exchange membrane including a cation exchange membrane and an anion exchange membrane and deionization using this ion exchange membrane Electrodeionization filter. [0004] Due to the fact that only simple studies have been conducted on ion exchange membranes and the lifetime of electrodes has not been considered sufficiently, however, conventional electrodeionization filters have a problem of ...
