Problems solved by technology

[0003] However, since the water near the anode is acidic and the water near the cathode is alkaline, it is easy to cause corrosion to the electrode plate
At the same time, there are no supports on both sides of the existing ionic membrane, and the pressure of water is likely to cause damage to the ionic membrane, so that the filter needs to be replaced and cleaned frequently

Abstract

The present invention discloses a filter. The filter comprises a bracket and a body arranged on the bracket. A raw water inlet, a fresh water inlet, a concentrated water outlet and a fresh water outlet are arranged on the body. The body comprises an upper cover, a lower cover, a plurality of anode plates and a plurality of cathode plates arranged in stacks alternately between the upper cover and the lower cover, and filter units are arranged between the two adjacent anode plate and cathode plate. By respectively attaching anode membrane subassemblies and cathode membrane subassemblies on the anode plates and cathode plates, the stress abilities of the anode membrane subassemblies and cathode membrane subassemblies are greatly improved. Due to the protections of the anode membrane subassemblies and cathode membrane subassemblies, the anode plates and cathode plates are more resistant to corrosion.

Description

technical field [0001] The invention relates to the field of water purification, in particular to a filter. 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 and alkali recovery, electroplating waste liquid treatment, and recovery of ...
