State Environmental Protection Administration 1999-00-00 released HCRJ--058--1999
1, range
1.1 the technical requirements of the ozone generator product classification, naming, requirements, reference standards, test methods, inspection rules, signs, packaging, transportation and storage.
1.2 the technical conditions apply to the ozone generator (hereinafter referred to as the generator) in environmental pollution control.
2 classification and nomenclature
2.1 classification
2.1.1 generator is divided into air gap discharge type (tube type, plate type) and other types of gas discharge according to the basic ozone generator.
The 2.1.2 generator is divided into frequency (50Hz/60Hz), intermediate frequency (1000Hz - 100Hz) and high frequency (> 1000Hz) according to the discharge frequency.
The 3.1.1 generator is divided into low concentration (less than 10mg/l), middle concentration (10-50mg/l) and high concentration () and high concentration (> 50mg/l) according to the generation of ozone concentration.
The 3.1.2 generator is divided into micro (1000mg/h), small (1 - 100g/h), medium (- 1000g/h) and large (100 -) and large (1kg/h) according to the ozone production. The number should be selected according to the following series: 1, 2, 3, 4, 5, 10, 15, 20, 25, 501002003005001000,,.......
3.2 naming
Generator naming and models with Chinese phonetic alphabet and Arabia digital representation.
Example: CF-G-1-500G, the power frequency tube ozone generator that produces 500g ozone per hour.
4 requirements
