Abstract

The invention discloses an improved roll-type electric desalter, which includes a central tube as one pole of the electrode and a shell, the other pole of the electrode is arranged on the shell, and anion and cation exchanges arranged alternately between the central tube and the shell The anion and cation exchange membrane divides the space between the central tube and the shell into a fresh water chamber and a concentrated water chamber, the fresh water chamber is filled with ion exchange resin, and a pair of adjacent anion and cation exchange membranes form a membrane bag, and the membrane bag is set The first water flow inlet and the first water flow outlet, one end of the central tube is provided with the second water flow inlet, the shell is provided with the second water flow outlet, and a water distribution pipe is respectively arranged at the two ends of the film bag, and the side wall of the water distribution pipe is provided with There are water distribution holes, and a screen is set adjacent to the water distribution pipe. After the improvement of the invention, the water distribution is uniform, the water flow rate is large, and the water flow enters and exits more smoothly; the occurrence rate of thick and fresh water crossing is smaller, and it is more convenient to arrange and maintain by pipelines.

Description

technical field [0001] The invention relates to a water treatment device in the field of water treatment, in particular to an improved coil type electric desalter. Background technique [0002] Electric desalination, the English name is abbreviated as EDI. Electric desalination combines electrodialysis and ion exchange technology, fills the fresh water chamber of the electrodialyzer with ion exchangers, and under the action of a DC electric field, realizes the process of electrodialysis, ion exchange desalination and ion exchange continuous electrical regeneration, which can Continuous production of high-quality pure water. [0003] Currently, there are existing electric desalters, such as the Chinese patent application number: 201410399732.2, which discloses a roll-type electric desalter. It includes a central tube as a pole of the electrode and a shell concentric with it. The fresh water chamber is filled with ion exchange resin, and a pair of anion and cation exchange m...
