Description

Technical Field

[0001] The present invention relates to the technical field of water purification devices, and more specifically, to a water purification device of an EDI module. Background Art

[0002] EDI (Electrodeionization), also known as continuous electric desalination technology, scientifically integrates electrodialysis technology and ion exchange technology. Through the selective permeation of cations and anions by cation and anion membranes and the exchange of ions in water by ion exchange resins, the directional migration of ions in water is achieved under the action of electric fields, thereby achieving deep purification and desalination of water. The hydrogen ions and hydroxide ions generated by water electrolysis are used to continuously regenerate the loaded resin. Therefore, the EDI water production process does not require acid or alkali chemical regeneration to continuously produce high-quality ultrapure water.

[0003] Existing EDI module water purification treatment devices such as the EDI module for water purification devices with publication number CN209367878U, include fixed plates on both sides of the shell, damping shafts on the front plate and rear plate of the fixed plate, telescopic rods movably mounted on the damping shafts, rollers on the telescopic rods, and further optimized, the controller is a PLC programmable controller, and the wireless communication module is a WiFi communication module or a 4G communication module. The EDI module for water purification devices described in the utility model sets the concentrated water outlet pipe and the extreme water outlet pipe to the same pipeline, which simplifies the structural design; can facilitate the replacement and maintenance of the resin block of the fresh water chamber; can monitor the flow of the outlet pipe, and timely discover the blockage of the equipment, which is suitable for wide promotion and application.

[0004] However, the existing EDI water purification device is prone to accumulation of impurities in the internal ion permeation membrane after long-term use. Therefore, the EDI water purification device needs to be cleaned or the ion permeation membrane needs to be replaced. No matter which method is used, the EDI water purification device needs to be stopped, which reduces the pure water production efficiency. If chemical cleaning is used, repeated cleaning is required afterwards, resulting in a waste of water resources. Summary of the invention

[0018] 4. The interior of the collecting device is hollow, and slots are provided at intervals of the collecting device corresponding to the outward expansion pieces.
