Abstract

The invention discloses a UV photocatalytic oxidation method and net cover equipment for treating VOCs and relates to the technical field of VOCs pollutant purification. A UV photocatalytic oxidationmethod and the UV photocatalytic oxidation net cover equipment are adopted, UV produced by a UV lamp excites electron transition of a catalyst to produce positive ions with an oxidation function, water on the surface of the catalyst is oxidized into hydroxyl radicals, meanwhile, transition electrons are captured by ozone adsorbed on the surface of the catalyst to form super-oxygen negative ions, and the super-oxygen negative ions and hydroxyl radicals oxidize organic matter into CO2 and H2O; meanwhile, UV at wavelength of 253.7 nm can change ozone in gas flow into oxygen negative ions and accelerate decomposition of the VOCs, so that the VOCS are treated efficiently.

Description

technical field [0001] The invention relates to the technical field of purification of VOCs pollutants, in particular to an ultraviolet photocatalytic oxidation method and mesh equipment for treating VOCs. Background technique [0002] In recent years, with the rapid development of industries, such as the rapid development of petroleum, chemical, dye, synthetic materials, and plastic industries, the air waste generated is increasing, causing large-scale invasion of smog all over the country, seriously endangering human health. . In particular, VOCs pollutants are mostly carcinogens. Excessive inhalation by the human body will lead to the emergence of various diseases and even cancer. Based on this, there are currently many methods and equipment for treating VOCs pollutants, but these methods have low treatment efficiency and high operating costs; these equipment have complex structures, low treatment efficiency, poor safety, instability, and high energy consumption, which i...
