Abstract

The invention discloses a plate-and-frame electric deionizing unit. One side of working zone of freah water room is equipped with a fresh water room opening (21) connected to it; said opening is used as filling port for filling or changing ion material, and is sealed by sealing baffle; the two relative sides in heavy concentration water room working zone paralleling to fresh water flowing direction are provided with water inlet (25) and outlet (26) for heavy concentration room respectively; said inlet and outlet extend along direction parallelling to fresh water flowing direction. It is convenient for said device to fill and change resin on the pot, and adjust the resin filling ratio; the sealing problem caused by resin particle is avoided; and the water flow direction of fresh water and heavy concentration water is in cross flow.

Description

technical field

[0001] The invention relates to an electrodeionization device, in particular to a device for removing ions in water by ion selective electroosmosis with plate and frame components. Background technique

[0002] Continuous electric desalination technology, also known as electrodeionization (hereinafter referred to as EDI technology), uses the combined action of ion-conducting materials (such as ion-exchange resins and ion-exchange membranes) and electric current to deionize ionic or ionizable fluids. A technique for separating substances (impurities). Since the EDI component does not need acid-base regeneration when in use, the water quality of the produced water can reach or exceed that achieved by the ion exchange method, and the water quality of the produced water is stable and can be operated continuously. The device occupies less land than the ion exchange method, and does not require In the field of pure water and ultrapure water manufacturing, EDI tech...
