Ozone generator is a device used to produce ozone gas (O3). Ozone is easy to decompose and cannot be stored. It needs to be prepared and used on site (short-term storage can be carried out under special circumstances), so ozone generators must be used in all places where ozone can be used. Ozone generators are widely used in drinking water, sewage, industrial oxidation, food processing and preservation, medical synthesis, and space sterilization. The ozone gas produced by the ozone generator can be used directly, or it can participate in the reaction by mixing with a liquid through a mixing device. Ozone is produced by ceramic plate with the principle of high frequency and high pressure. The gas source is air, without any other raw materials. Use the broad-spectrum, high-efficiency and rapid sterilization function of ozone to sterilize indoor air, oxidize and denature the protein shell of bacteria, fungi and other bacteria, thereby killing bacterial propagules and spores, viruses, fungi, etc. A variety of toxic ingredients (such as formaldehyde, benzene, ammonia, smoke and organic substances with odor) produce oxidation reactions to eliminate the odor and release its toxicity.
