Abstract
Description
Technical Field
[0001] The invention relates to a regional direct drinking water pipe network pipeline disinfection and sterilization device, belonging to the field of ozone sterilization technology and application. Background Art
[0002] Since the water in the regional drinking water network does not contain residual chlorine and other antibacterial agents, it is easy to be contaminated and breed bacteria and mold, which is particularly serious in the hot season, which will seriously affect people's health. Ozone can be applied to this field as an efficient, broad-spectrum, and residue-free sterilization technology. However, since the conductivity of regional drinking water is relatively low, even lower than 5µs / cm, the ozone water manufacturing device that directly electrolyzes tap water is not suitable for such application fields. Summary of the invention
[0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a regional direct drinking water pipe network pipeline disinfection and sterilization device.

[0005] Furthermore, the ozone water manufacturing device includes an ozone water generator shell, an ozone water generator cover, and a top shell. The ozone water generator cover is connected to the ozone water generator shell, and the ozone water generator cover is inserted into the top shell and connected; a control panel is provided in the top shell, and a touch key is provided on the control panel.

[0006] Furthermore, the ozone water generator plate assembly includes n plate units, n is a natural number ≥1, each plate unit includes 1 coated titanium anode plate, 2 cathode plates and 2 proton exchange membranes, proton exchange membranes are provided on both sides of the coated titanium anode plate, and cathode plates are provided on the outside of the proton exchange membrane; a plurality of evenly distributed anode plate holes are provided on the coated titanium anode plate, a plurality of evenly distributed cathode plate holes are provided on the cathode plate, and a plurality of evenly distributed exchange membrane holes are provided on the proton exchange membrane, and the positions of the anode plate holes, the cathode plate holes and the exchange membrane holes correspond to each other; the coated titanium anode plates of each plate unit are connected and electrically connected to the anode conductive sheet; the cathode plates of each plate unit are connected and electrically connected to the cathode conductive sheet; anode conductive studs are provided on the anode conductive sheet, and cathode conductive studs are provided on the cathode conductive sheet.
[0007] Furthermore, the coated titanium anode plates of each plate unit are connected to the anode conductive sheet through anode fixing screws, conductive pillars and anode fixing nuts; the cathode plates of each plate unit are connected through evenly distributed cathode fixing screws, conductive pillars and cathode fixing nuts, and the cathode conductive sheet is connected to one of the cathode fixing screws and cathode fixing nuts.

The direct drinking water network pipeline disinfection and sterilization device is directly connected to the direct drinking water network pipeline. When the control board supplies power to the anode and cathode of the electrolytic ozone water generator, hydrogen ions are transferred to the cathode through the proton exchange membrane to generate hydrogen. The anode side generates ozone under the action of the anode plate catalyst coating. A part of the ozone is dissolved and mixed in the water to directly generate ozone water. Ozone that is not dissolved in water is stored in the form of ozone gas above the inside of the generator container. When water passes through the ozone generator, it promotes the generation of ozone water and ozone gas to sterilize the pipeline and outlet valve flowing through it in a comprehensive and dead-end-free manner.
