Description

Technical Field

[0001] The invention belongs to the technical field of water purification, and in particular relates to a double-sided water electrolysis device. Background Art

[0002] Electrolyzed water usually refers to the product generated by electrolysis of water containing salt (such as sodium chloride). The electrolyzed water itself is neutral, and other ions can be added, or it can be separated by a semi-permeable membrane to generate two types of water. One is alkaline ion water, and the other is acidic ion water. Electrolyzed water with sodium chloride as the electrolyte contained in the water will contain sodium hydroxide, hypochlorous acid and sodium hypochlorite after electrolysis (if pure water is electrolyzed, only hydroxide ions, hydrogen, oxygen and hydrogen ions will be produced).

[0003] In the invention patent application document with application number 201911061246.9, a small electrolyzed water device and its system are disclosed. The document also discloses the following information: electrolyzed water is divided into strong acid electrolyzed water pH2.3-2.7, strong alkaline electrolyzed water pH11-11.5, weak acid electrolyzed water pH5-6, electrolyzed hypochlorite water pH8-9 and alkaline ion water pH8-10 according to the pH value of the acidity and alkalinity index. Among them, the strong acid electrolyzed water is known for its strong bactericidal power and good safety. Its bactericidal objects are not limited to general bacteria, but also have the effect of killing HIV, HBV and Bacillus. It has a wider applicability than glutaraldehyde and disinfectant ethanol, so it is widely used as a cleaning agent to prevent infection, a disinfectant for medical equipment, and a disinfectant for human skin and mucous membranes.

[0004] At present, in the production of strong acid electrolyzed water, it is usually produced by injecting less than 0.1% salt water into an electrolytic cell equipped with an anode, a cathode, and a separator between the anode and the cathode, and then electrolyzing it. The electrolytic cell is the key equipment for producing strong acid electrolyzed water. The commonly used electrolytic cells are generally double-barreled and use plate electrodes. Under low voltage and low current electrolysis conditions, the electrolysis efficiency is low and cannot meet the water supply requirements of continuous and large amounts of electrolyzed water with a specified pH value in a short period of time, such as when cleaning medical instruments such as endoscopes in hospitals.

[0005] However, currently known hypochlorous acid water generators are mainly used in industry, and are generally complex in structure, large in size, expensive and have high maintenance costs. In recent years, with the frequent occurrence of infectious diseases, as a means of preventing infection, the market needs small, cheap, reliable and widely applicable electrolyzed water production equipment to meet the daily needs of residents' homes or community health care stations and hospitals.

[0006] Therefore, in view of the problems that the electrolytic water preparation device in the prior art has a complex structure, troublesome maintenance and limited scope of application, it is necessary to provide a more reasonable technical solution to solve the current technical problems. Summary of the invention

[0007] The purpose of the present invention is to provide a double-sided electrolytic water device to solve the problems of complex structure, troublesome maintenance and limited scope of application of electrolytic water preparation devices in the prior art.

[0009] Wherein, electrolytic membranes are respectively arranged on both sides of the anode frame in sequence, the electrolytic membranes are located between the anode frame and the cathode frame, and the cathode frame is fixedly connected to the anode frame by fasteners, so that the electrolytic membrane and the upper second cavity of the cathode frame together form a cathode chamber;

[0010] The leakage plates are provided in two pairs, each pair of leakage plates is respectively attached to the two sides of the electrolytic membrane, and the leakage plates are sealed and connected to the anode frame and the cathode frame; wherein the leakage plates are also provided with a plurality of leakage holes arranged in an array, so that the liquid in the anode chamber can flow to the cathode chamber through the leakage holes;

[0011] The cathode frame is provided with an electrolyte inlet for introducing electrolyte and an electrolyte outlet for leading out electrolyte; the water inlet, water outlet, electrolyte inlet and electrolyte outlet are all provided with pipe joints;

[0012] An anode plate is arranged in the anode chamber, and the anode plate is electrically connected to the external positive pole of the power supply; a cathode plate is arranged in the cathode chamber, and the cathode plate is electrically connected to the external negative pole of the power supply.

[0013] In a possible design, the anode frame and the cathode frame are both provided with grooves for accommodating annular gaskets; the annular gaskets are embedded in the grooves in a one-to-one correspondence; and the orifice plates are pressed against the annular gaskets.

[0014] In a possible design, the cross section of the groove is semicircular.

[0016] In a possible design, the leakage holes are configured as circular holes; the leakage holes are arranged in a circle.

The double-sided electrolysis water device can quickly change the pH value of the electrolyzed water, and the pH value can be as high as 12, thereby achieving effective control of the pH value of the electrolyzed water. The electrolysis water device can significantly increase the effective electrolysis area of ​​the electrolysis electrode by electrolyzing water on both sides at the same time, thereby greatly improving the electrolysis efficiency of the electrolysis water device. Therefore, while ensuring the efficiency and quality of electrolyzed water, the structure of the device is optimized to reduce the space occupied.
