Ozone is named after its knife like fishy smell, which can be self reduced to oxygen at room temperature. Compared to oxygen, it is soluble in water and easily dispersed. Ozone is composed of an oxygen atom carried by oxygen molecules, which determines that it is only in a temporary storage state. The oxygen atoms carried are oxidized and used up, and the remaining combine to form oxygen and enter a stable state, so ozone does not have secondary pollution.

Ozone generator is a machine that produces ozone. A generator is a purification device for air or water. Its main purpose is to use ozone to kill bacteria and filter pollutants.

Ozone generator is an internally heated gas-phase reactor. Because gases such as air are poor thermal conductors, the heat generated by corona discharge can raise the temperature of the gas. Higher temperatures accelerate the reverse reaction of ozone, where ozone is reduced to oxygen, thereby reducing ozone production. Therefore, cooling the ozone generator is also a measure to improve its efficiency. Due to the much higher heat absorption coefficients of water and oil compared to air, industrial generators generally use water-cooled or oil cooled generators. Due to the convenience and ease of air cooling, this form is commonly used in micro ozone generators.

Ozone generators that use water cooling should consider the quality of the cooling water to prevent scaling and affect the heat dissipation of the ozone generator, thereby reducing ozone output and increasing maintenance costs. Therefore, if the quality of the cooling water is poor, it is necessary to add a plate cooler.
