Description

Technical Field

[0001] This utility model relates to the field of electro-deionization water purification technology, and more specifically to an electro-deionization water purification device. Background Technology

[0002] Electro-deionization water purification devices can remove impurities such as ions, organic matter, and particulate matter from water. They adsorb and migrate anions and cations in the water to the electrode area, achieving deep purification of water. They can effectively remove harmful substances such as heavy metals, bacteria, and viruses, improve water quality, and are widely used in the electronics, pharmaceutical, and chemical industries, as well as in the preparation of ultrapure water in laboratories, ensuring water safety and quality.

[0003] During operation, prolonged use can lead to a decrease in the durability of the rubber diaphragm, causing it to gradually become saturated and lose its ion exchange capacity. This reduces the system's desalination efficiency, preventing the effective separation and removal of positive and negative ions in the water. Consequently, the quality of the effluent may be affected and may not meet the expected purity standards. Furthermore, microorganisms in the water may not be effectively controlled, increasing the risk of microbial contamination. Organic matter and microorganisms in the water may also be difficult to fully oxidize and remove. Utility Model Content

[0022] The sterilization component 4 includes a hollow tube 401 and an ultraviolet emitter 402. The hollow tube 401 is fixedly installed on the lower inner wall of the outer casing 101, and the ultraviolet emitter 402 is distributed in a ring and fixedly installed on the inner wall of the outer casing 101.

[0023] The auxiliary component 5 includes an ozone generator 501, a circular tube 502, and an air inlet pipe 503. The ozone generator 501 is fixedly installed at the bottom of the outer casing 101. The output end of the ozone generator 501 is fixedly connected to the outer wall of the circular tube 502. The air inlet pipe 503 is distributed in a ring.

[0024] The working principle of this utility model:

[0025] First, connect the inlet 102 of the device to the water inlet and the outlet 103 to the water outlet. At this point, the device can start working.

[0026] Secondly, after the water enters the inlet 102, the rubber diaphragm 2 efficiently adsorbs and removes anions and cations, including dissolved salts, from the water. Its high selectivity and adsorption capacity ensure deep purification of the water quality, and the resistivity of the effluent can reach above the conventional standard value, meeting the requirements for high-purity water. After the first treatment, when the water touches the positive electrode 303 and the negative electrode 304, the battery 301 supplies power to the positive electrode 303 and the negative electrode 304 through the connecting pipe 302. The water migrates directionally under the action of the electric field, accelerating the ions towards the resin diaphragm or the concentrate. The movement of the chamber improves deionization efficiency and also helps prevent membrane fouling, extending equipment life. The water after secondary treatment is relatively pure. At this time, the ultraviolet emitter 402 starts to work and emits ultraviolet light. At the same time, the output end of the ozone generator 501 injects ozone into the outer casing 101 through the round tube 502 and the air inlet pipe 503. Ozone has strong oxidizing properties and can quickly kill pathogens in the water and oxidize and decompose organic matter, odors and colors. Working in conjunction with the ultraviolet emitter 402, it can further oxidize residual pollutants and improve water quality safety.
