UV Photocatalytic Oxidizer

UV Photocatalytic Oxidizer

Professional Process Equipment Supplier

1. Product Overview

The UV Photocatalytic Oxidizer is an air purification device that utilizes UV-C ultraviolet radiation combined with a photocatalyst (TiO₂) and ozone to decompose malodorous gases and volatile organic compounds (VOCs). The equipment irradiates exhaust gas with specially designed high-energy UV-C light beams to break organic molecular bonds, while simultaneously generating ozone from oxygen molecules and activating the TiO₂ photocatalyst to produce highly reactive hydroxyl radicals. The synergistic action of ozone and hydroxyl radicals oxidizes and decomposes organic compounds into low-molecular-weight substances, carbon dioxide, and water. UV photocatalytic oxidizers offer a compact footprint, low operating cost, no secondary pollution, and simple maintenance, making them well suited to commercial kitchen exhaust, odor control at waste transfer stations and wastewater treatment plants, and VOCs abatement in spray booths.

2. Working Principle

The UV photocatalytic oxidizer operates on the synergy of photochemical oxidation and photocatalysis, through the following processes: First, when malodorous and VOCs-laden exhaust gas enters the purifier, it is irradiated by high-energy UV-C lamps emitting dual-wavelength ultraviolet light at 185nm and 254nm. The 185nm wavelength ionizes oxygen molecules in the air to produce ozone (O₃) and free oxygen (O), while the 254nm wavelength activates the titanium dioxide (TiO₂) photocatalyst surface to generate highly reactive hydroxyl radicals (·OH). Simultaneously, the high-energy UV beams directly cleave the molecular bonds of organic malodorous compounds, degrading them into lower-molecular-weight fragments. Ozone and hydroxyl radicals, as extremely powerful oxidizers, rapidly oxidize and decompose these organic fragments, ultimately converting them into harmless substances such as CO₂ and H₂O. The purified gas is discharged through the exhaust stack in compliance with emission standards. The entire process operates at ambient temperature and pressure without additional heating, ensuring safe and reliable operation.

6. Typical Application Fields

Food Service Industry: Kitchen exhaust purification in restaurants, hotels, and canteens. Effectively removes oil mist particles and odors, meeting cooking fume emission standards and improving surrounding air quality.

Waste Management: Odor treatment at waste transfer stations, landfills, and composting facilities. Removes hydrogen sulfide, ammonia, and mercaptans, improving the living environment for nearby residents.

Wastewater Treatment: Odor purification from pump rooms, sludge dewatering rooms, and aeration tanks at sewage treatment plants. Removes H₂S, NH₃, and VOCs to ensure compliance with air quality standards.

Spray Coating: VOCs treatment from small spray booths and repair rooms. Combined with pre-filtration of paint mist, removes organic solvent odors and harmful components.

Other Industries: Food processing odors, livestock farm emissions, pharmaceutical workshop exhaust, and various low-to-medium concentration odor and VOCs treatment scenarios.
