Ultraviolet purification of oil fume is to degrade oil fume macromolecules into low molecules through high-energy radiation (wavelength 185nm) to reduce oil fume emission, so as to achieve the purpose of oil fume purification.
Grease deposition is easy to form in the range hood and exhaust pipe in a large kitchen, resulting in high cleaning cost, bad smell and increasing the risk of fire. Ultraviolet fume purification can prevent the kitchen from oil pollution and eliminate the peculiar smell of waste gas. It is treated with high-energy ultraviolet radiation to decompose, destroy and neutralize the molecules of oil and smell. Thus, the surface of the kitchen range hood is kept clean and bright, and the cleaning of the exhaust passage is greatly reduced.
