Problems solved by technology

[0006] The purpose of the present invention is to provide a kind of salt-adding electrodialysis device and its use method, to solve the existing salt-adding electrodialysis device on the market proposed by the above-mentioned background technology in the process of using, need regularly to add salt electrodialysis The ionic membrane inside the device is cleaned, and the ionic membrane is generally cleaned by a fixed cleaning solution, so that when cleaning the ionic membrane, if there is a certain element in the fouling substance on the surface of the ionic membrane that is relatively low, the cleaning solution The content of some substances in the cleaning solution is relatively high, so the high content of substances in the cleaning solution will cause corrosion to the ion membrane and reduce the cleaning effect.

Abstract

The invention discloses a salting electrodialysis device and a using method thereof. The salting electrodialysis device comprises a salting-out outer shell, at least six external fixing bases are arranged above the salting-out outer shell, a cation membrane, an anion membrane and an electrode membrane are arranged in the salting-out outer shell, and sampling mechanisms or sealing covers are arranged in through holes in the outer walls of the external fixing bases; and the sampling mechanism is positioned among the cation membrane, the anion membrane or the electrode membrane. According to the salting electrodialysis device and the use method thereof, the sampling structure is arranged, impurities on the surface of an ionic membrane in the device can be rapidly sampled, a sample can be detected after being sampled, a cleaning solution is prepared according to the content of substances in the sample, therefore, the surface of the ionic membrane can be effectively cleaned according to the prepared cleaning liquid, the cleaning effect of the device is improved, meanwhile, the condition that the ionic membrane is corroded can be reduced, and the service life of the ionic membrane is prolonged.

Description

technical field [0001] The invention relates to the technical field of electrodialysis devices, in particular to a salt-adding electrodialysis device and a method for using the same. Background technique [0002] The method of using the selective permeability of semipermeable membranes to separate different solute particles (such as ions) is called dialysis. When dialysis is performed under the action of an electric field, the phenomenon that charged solute particles (such as ions) in the solution migrate through the membrane is called electrodialysis. The technology of using electrodialysis to purify and separate substances is called electrodialysis. It is a new technology developed in the 1950s. It was originally used for seawater desalination and is now widely used in chemical industry, light industry, metallurgy, papermaking, and medicine. Industry, especially the preparation of pure water and the treatment of the three wastes in environmental protection, such as acid a...
