What is Plasma Air Purifier
The plasma Air Purifier operates by applying a high-voltage alternating current (AC) across two insulated blocking media, creating high-energy plasma between them. The active particles in the plasma, such as high-energy ions and free radicals, then collide with organic molecules or molecular clusters in the exhaust gas. This interaction causes the molecules to break down quickly, helping to degrade the pollutants. During the plasma chemical reaction, high-energy ions gain energy from the electric field and transfer it to the organic molecules or molecular clusters through excitation or ionization. This results in the molecules either decomposing or being excited into active groups. These active groups then collide with oxygen and other active groups, forming stable products and releasing heat, which helps purify the organic molecules or clusters.
The plasma purifier also generates significant amounts of ozone, a strong oxidizer, which can oxidize organic gases into water and carbon dioxide. This oxidation process further neutralizes harmful chemicals and odors, improving air quality. Plasma purifiers primarily target gaseous organic molecules or molecular clusters, relying on chemical reactions to break down and oxidize these pollutants. They are particularly effective in industries where organic emissions are a significant concern, helping to purify the air and make it safer for workers and the environment.
The working Principle of Plasma Air Filter
High-Voltage Plasma Generation
The plasma air purifier operates by applying a high-voltage alternating current (AC) across two insulated blocking media. This creates high-energy plasma between the media.
Degradation of Pollutants
The active particles in the plasma, such as high-energy ions and free radicals, collide with organic molecules or molecular clusters in the exhaust gas. This causes the molecules to break down rapidly, helping to degrade the pollutants.
Plasma Chemical Reaction
During the process, high-energy ions gain energy from the electric field and transfer it to the organic molecules or molecular clusters through excitation or ionization. This results in the molecules either decomposing or being excited into active groups. These active groups then collide with oxygen and other active groups, forming stable products and releasing heat, which purifies the organic molecules or clusters.
Ozone Generation and Oxidation
The plasma purifier also produces significant amounts of ozone, a strong oxidizer. Ozone can oxidize organic gases, converting them into water and carbon dioxide. This oxidation process helps neutralize harmful chemicals and odors, improving air quality.
What is Electrostatic Air Purifier
The working principle of a high-voltage electrostatic oil mist purifier is to use a high-voltage direct current (DC) electric field to charge small liquid and solid particles in the exhaust gas. Under the influence of the electric field, these charged particles are attracted to the collection plates, where they are separated from the gas. The liquid droplets that are adsorbed onto the plates flow under gravity to an oil collection tray and are then drained out through an oil discharge channel. The purifier mainly targets small particles such as oil mist and dust, and its operation relies on physical processes like charging and adsorption. Additionally, the purifier generates some ozone, which can oxidize certain organic gases, helping to eliminate some of the odors in the smoke. The target pollutants are primarily small liquid or solid particles present in smoke and mist emissions. These purifiers are highly effective at capturing and neutralizing such particles, significantly improving air quality and reducing environmental impact.

High-voltage electrostatic oil mist purifiers are widely used for purifying oil mist and smoke generated in the catering industry and industrial production. Their primary application includes:
Catering Industry (Restaurant Kitchens):
Used to clean cooking fumes from kitchen exhaust systems in restaurants.
The device effectively removes fine solid and liquid particles in the smoke, ensuring cleaner air and compliance with environmental regulations.
Industrial Applications:
Utilized in food processing plants to handle emissions from frying, baking, or roasting operations.
Applied in chemical manufacturing processes where oil mist or particulate emissions are produced, ensuring a safer and cleaner working environment.
