Reverse osmosis direct drinking water machine performing disinfection by using low-voltage electrolysis technology

Abstract

The invention provides a reverse osmosis direct drinking water machine performing disinfection by using a low-voltage electrolysis technology. The reverse osmosis direct drinking water machine comprises: a water storage tank, wherein a plurality of partition plates are arranged in the water storage tank, are alternately distributed on the left side wall and the right side wall in the water storagetank in the height direction, and are partially overlapped in the height direction; and a PEM electrolysis device, wherein the PEM electrolysis device comprises a hydrogen electrolysis cathode cavityand an ozone electrolysis anode cavity, the hydrogen electrolysis cathode cavity and the ozone electrolysis anode cavity are relatively independent, the water inlet pipeline and the water outlet pipeline of the hydrogen electrolysis cathode cavity are respectively connected to two hydrogen water holes formed in the side wall of the upper portion of the water storage tank, and the water inlet pipeline and the water outlet pipeline of the ozone electrolysis anode cavity are respectively connected to two ozone water holes formed in the side wall of the bottom plate of the water storage tank. According to the invention, reverse osmosis pure water can be directly used as the stock solution, ozone generated by the anode and water have a certain mixing degree, the innovative multi-layer partition plate structure can replace the common complex gas-liquid mixing mode, mixing is performed layer by layer from the bottom, and the efficient sterilization is conducted on the whole pure water tank.

Description

technical field [0001] The invention relates to the field of disinfection and sterilization, in particular to a reverse osmosis direct drinking water dispenser which uses low-voltage electrolysis technology for disinfection. Background technique [0002] Ozone O 3 As one of the strongest oxidants, it has been quite effective in the fields of sterilization, disinfection, pesticide degradation, and environmental governance. In particular, ozone has a strong oxidizing ability, safe and thorough sterilization, and does not pollute the environment, and is finally reduced to oxygen. [0003] The development of solid polymer electrolyte membrane (Polymer Electrolysis Membrane, referred to as PEM) technology has promoted the low-voltage electrolysis method to show unique advantages, including the concentration can be as high as 18%-20%; the raw material is relatively pure water, and the by-product is only H 2 , O 2 , no by-product pollution. In addition, the PEM low-voltage elec...

Problems solved by technology

[0004] Existing reverse osmosis direct drinking water dispensers generally use small-flow reverse osmosis membranes to produce water.

During the storage process, bacteria in the air enter the water tank and breed, causing the total number of colonies to exceed the standard, which poses a hidden danger to drinking water hygiene and safety

Existing solutions generally use ultraviolet lamps, but there are problems such as short service life, difficulty in irradiating dead angles, and UV-resistant materials; there is also the use of high-pressure ozone gas, through aeration, jet flow, etc., but there will be low utilization efficiency and side effects.
