1. According to the generator's high-voltage electric frequency, there are three types: power frequency (50-60Hz), intermediate frequency (400-1000Hz) and high frequency (>1000Hz). Power frequency generators have basically withdrawn from the market due to their shortcomings such as large size and high power consumption. Medium and high-frequency generators have the advantages of small size, low power consumption, and large ozone output, and are the most commonly used products.
2. According to the gas raw materials used, there are two types: oxygen type and air type. The oxygen type is usually supplied with oxygen from an oxygen cylinder or an oxygen generator. Air type usually uses clean and dry compressed air as raw material. Because ozone is produced by oxygen, and the oxygen content in the air is only 21%, the concentration of ozone produced by the air-type generator is relatively low, and the oxygen purity of the bottled or oxygen generator is above 90%, so the oxygen-type The ozone concentration of the generator is relatively high.
3. According to the cooling method, there are water-cooled and air-cooled. When the ozone generator is working, it will generate a lot of heat energy and needs to be cooled, otherwise the ozone will be decomposed due to the high temperature. The water-cooled generator has good cooling effect, stable operation, no ozone attenuation, and can work continuously for a long time, but the structure is complicated and the cost is slightly higher. The air-cooled cooling effect is not ideal, and the ozone attenuation is obvious. High-performance ozone generators with stable overall performance are usually water-cooled. Air cooling is generally only used for low- and medium-grade ozone generators with small ozone production. When choosing a generator, try to choose a water-cooled type.
4. Divided by dielectric materials, there are common types of quartz tubes (a type of glass), ceramic plates, ceramic tubes, glass tubes and enamel tubes. Ozone generators made of various dielectric materials are sold on the market, and their performance is different. The low cost and stable performance of glass dielectric is one of the earliest materials used for artificial ozone production, but its mechanical strength is poor. Ceramics are similar to glass, but ceramics are not suitable for processing, especially when used in large-scale ozone generators. Enamel is a new type of dielectric material. The medium and the electrode are integrated with high mechanical strength and high precision machining accuracy. It is widely used in large and medium-sized ozone generators, but the manufacturing cost is relatively high.
5. According to the structure of the ozone generator, there are two types: Dielectric Barrier Discharge (DBD) and Open Type.
6. According to the structure of the discharge chamber of the ozone generator, there are two types: tube type and plate type.
