The salt positive ions are absorbed by the cation exchange resin in the cation absorption unit layer, the hydrogen ions are replaced to form free hydrogen ions, and the replaced free hydrogen ions enter the next-stage anion absorption unit layer along with the raw water. In the anion adsorption unit layer, the salt anions in the raw water are replaced by hydroxide ions in the anion adsorption unit layer, the salt anions are adsorbed by anion exchange resin in the anion exchange unit layer, and the hydroxide ions are replaced to form free hydroxide ions. The free hydroxyl ions combine with the free hydrogen ions to form purified pure water, which is discharged as pure water.
The electrode plate comprises a positive electrode plate and a negative electrode plate, a water inlet waterway of the regeneration waterway is formed by a gap between the positive electrode plate and the anion exchange membrane, a water outlet waterway of the regeneration waterway is formed by a gap between the negative electrode plate and the cation exchange membrane, and the water inlet waterway of the regeneration waterway is connected with the water outlet waterway of the regeneration waterway.
The principle of the regeneration water path of the water purifier of the embodiment is as follows:
and under the regeneration working condition, the desalination waterway is closed. Raw water enters a regeneration water path of the desalination, filtration and purification device, and the electrode plates are electrified. The water generated by the hydrogen ions and the hydroxide ions between the cation adsorption unit and the anion adsorption unit of each stage is decomposed into the hydrogen ions and the hydroxide ions again under the action of the electrolysis voltage. Due to the action of the positive electrode plate, the hydroxide ions move towards the direction of the positive electrode plate, in the moving process, the hydroxide ions replace the salt negative ions adsorbed in the anion exchange resin, the salt negative ions become free salt negative ions, and the salt negative ions enter the water inlet waterway of the regeneration waterway through the anion exchange membrane.
Meanwhile, the electrolyzed hydrogen ions move towards the direction of the negative electrode plate, in the moving process, the hydrogen ions replace the salt positive ions adsorbed in the cation exchange resin, the salt positive ions become free salt positive ions, and the free salt positive ions enter the water outlet waterway of the regeneration waterway through the cation exchange membrane.
In the regeneration water path, the free salt positive ions and the free salt negative ions are combined, and the compound is used as concentrated drainage water through the water path, and the concentrated drainage water is drained from the water outlet water path of the regeneration water path along with the raw water.
The water purifier of the embodiment is provided with a plurality of stages of cation adsorption units and anion adsorption units which are overlapped by a desalination filtration purification device, and carries out desalination filtration and resin regeneration on raw water. Under the operating mode of desalination filtration, the raw water gets into multistage ion adsorption unit's desalination filtration purifier, and salt positive ion and salt anion in the raw water are adsorbed by the resin of every grade to replace hydrogen ion and hydroxyl ion in the resin, resin among the multistage ion adsorption unit can maximum absorption raw water salt positive ion and salt anion, and hydrogen ion and hydroxyl ion chemical combination form the high pure water of purity.
