The ozone of ozone test chamber is generated by ozone generator, currently there are three ways: high voltage discharge type, ultraviolet irradiation type and electrolysis type. High-voltage discharge type is currently the zui widely used ozone generator in related industries at home and abroad, widely used in the field of environmental testing.
The high-voltage discharge generator uses a high-voltage current of a certain frequency to create a high-voltage corona electric field, so that the oxygen molecules in or around the electric field undergo electrochemical reactions to produce ozone. This kind of ozone generator has mature technology, stable operation, long service life and large ozone output (single machine can reach 1Kg/h).
The uv ozone test chamber uses ultraviolet rays of a specific wavelength (185mm) to irradiate oxygen molecules to decompose the oxygen molecules to generate ozone. Due to the large size of the ultraviolet lamp, low ozone production and short service life, this generator has a narrow range of use and is often used on disinfection cupboards.
Electrolytic generators usually generate ozone by electrolyzing clean water. The generator can produce high-concentration ozone water, has low manufacturing cost, and is easy to use and maintain. However, due to the shortcomings of ozone production cannot be increased, electrode life is short, ozone is not easy to collect, etc., its scope of use is limited. At present, this generator is only used on some specific small equipment or in some specific places, and does not have the conditions to replace the high-voltage discharge generator.
