Process principle of external ozone generator
Date: 2025-07-31Read: 4
The process principle of an external ozone generator is to generate high concentration ozone through an independent ozone generation unit, and then transport it to the target area for disinfection or oxidation treatment through a pipeline system. The core process flow is as follows:
1、 Principle of Ozone Generation
1. High voltage ionization conversion
After an external gas source (air or oxygen) enters the generator, a glow discharge (corona discharge) is formed between the high-voltage electrodes, and oxygen molecules (O ₂) are ionized into active oxygen atoms (O), which then polymerize into ozone (O3). The chemical reaction formula is: 3O ₂ → 2O3.
2. Air source pretreatment
Air type: Compressed air needs to be dried and filtered to remove moisture and impurities, ensuring stable ozone production.
Oxygen type: Directly introduce high-purity oxygen (such as supplied by an oxygen concentrator) to increase ozone concentration and efficiency.
2、 Process characteristics of external system
1. Separate design
The ozone generation unit is independent of the application site and is connected to the central air conditioning system or gas distribution network through corrosion-resistant pipes (such as stainless steel) to transport ozone gas to multiple workshops or enclosed spaces.
2. Efficient cooling mechanism
Adopting a water cooling system to forcibly cool the discharge unit, avoiding ozone decomposition caused by high temperature, and maintaining stable ozone concentration (air-cooled type is prone to decay and not suitable for large equipment).
3. Ozone delivery and diffusion
Ozone gas is driven by a fan into the air conditioning duct and evenly distributed to the target area along with the airflow; When there is no central air conditioning, direct injection into the space through distributed pipelines ensures sterilization coverage (up to 100000 level cleanliness standards).
4. Security control
The built-in voltage regulator stabilizes the high-voltage power supply (approximately 15000V), equipped with electrical protection modules (such as overload protection) and ozone leakage monitoring to ensure safe operation.
3、 Application Process Example
1. Gas pathway: air/oxygen → drying and filtering → high voltage discharge ionization → ozone generation;
2. Transportation path: ozone gas → pipeline network → central air conditioning or fan → target space;
3. Exhaust gas treatment: Residual ozone is discharged through the return air outlet or decomposed by activated carbon to ensure safe emissions.
4. Key advantages: External design avoids direct contact of ozone with internal components of the device, extending its lifespan; Supports multi-point and large space disinfection, suitable for clean places such as pharmaceutical workshops and food factories.
