Guanglan CEC series UV photolysis 8000 air volume fume purifier

Equipment Introduction 2.1 Equipment purpose

Guanglan Environmental Protection's TL-Photocatalytic UV Odor Removal Equipment is a waste gas treatment device designed to manage odors generated during cooking processes in Chinese and Western catering kitchens, as well as from industrial VOCs. This equipment features stable operation, long service life, simple operation, and convenient maintenance and cleaning. It is a basic model that meets the needs of kitchen and industrial odor removal and treatment.

The UV photolysis purification system utilizes a UV lamp that emits ultraviolet light in two bands: 254nm and 185nm. The dedicated 254nm ultraviolet light breaks down the molecular chains of odor gases, forming active small molecules. Meanwhile, the 185nm ultraviolet light reacts with oxygen in the air to produce ozone, which then "cold burns" the active small molecules into water, carbon dioxide, and trace amounts of white powder. The organic compounds in the odor are photolytically oxidized, significantly reducing the odor.

The flue gas processed by the equipment must be discharged through a pipeline to an open outdoor area. The height of the discharge outlet should comply with the standards set by relevant national regulations, and the outlet should not be directed towards trees, walls, residents' balconies, or other objects.

Photolysis principle Photolysis

UV-C ultraviolet C-band (254nm) beam radiation cuts small oil particles (protein molecules composed of amino acids, fat molecules composed of fatty acids, etc.) into smaller pieces, altering the molecular structure of the oil. Oils and volatile organic compounds are easily attacked by UV-C.

·O + UV → 2O

·H O + UV → ·OH +·H → ·OH + H O VOC molecules are destroyed and decomposed

UV-C ultraviolet C-band (185nm) reacts with oxygen in the air during operation to generate ozone (O3).

Ozone is a strong oxidant that permanently oxidizes and decomposes molecules such as alcohols, esters, aldehydes, and benzene derivatives present in odors into harmless compounds like water vapor and carbon dioxide, thereby reducing odor-causing compounds.

 

Photocatalytic principle

By irradiating with light of a specific wavelength, the nanometer photocatalyst is activated, generating electron-hole pairs. These pairs interact with the surrounding H2O and O2 molecules, combining to form hydroxyl radicals ·OH. These hydroxyl radicals ·OH can layer by layer lock various harmful components in the air and decompose the molecular structure of harmful components, inhibiting bacterial growth and viral activity, thus achieving the purposes of sterilization, air purification, deodorization, mold prevention, and elimination of air pollution.
