Description

A long-life ozone generator

technical field

The present application relates to the technical field of ozone preparation, in particular to a long-life ozone generator.

Background technique

Ozone has environmental protection functions such as sterilization, elimination of odor, and degradation of COD. It has strong oxidizing properties and is not easy to store. It can rapidly oxidize and decompose harmful substances such as bacteria, viruses, Escherichia coli, mold, fungal spores, organic matter, inorganic matter, and kill 300-600 times faster than chlorine. There are many compounds that use chlorination properties to kill microorganisms to achieve bactericidal effect, but such bactericides such as ordinary chlorine, bleaching powder potassium permanganate are slower than ozone sterilization, and ordinary bactericides are harmful to human body. Ozone can destroy the biological structure of microorganisms such as bacteria and viruses in a short time, making them lose their viability. Because of its strong sterilization ability, it has been applied to various fields instead of conventional sterilization. The ozone gas produced by the ozone generator can be used directly, or it can be mixed with liquid through a mixing device to participate in the fusion. A certain concentration of ozone is not harmful to the human body and the environment.

An existing ozone generator adopts the principle of high voltage discharge. Convert oxygen to ozone. The high-voltage alternating current is applied to the high-voltage electrode with an insulator and a certain gap in the middle, and the passing air and oxygen are allowed to pass through. When the high-voltage alternating current reaches several thousand volts, a corona is generated, and the free high-energy ions in the corona dissociate the O2 molecule. The collision polymerized into 03 molecules. The production concentration of ozone varies with the applied supply voltage and current.

However, the existing ozone generator generates ozone through the high-voltage discharge of the metal electrode, and at the same time, it will also corrode the metal, form impurity rust on the surface, accumulate on the metal surface, and gradually the amount of ozone will become less and less efficient.
