Abstract

The invention discloses an oxidizing agent and ultraviolet light cooperating organic waste gas purification device and a processing method. The device is composed of an oxidizing agent humidification system and an oxidation reaction system. The oxidizing agent humidification system is composed of a waste gas induced draught fan, a high-pressure pump and a humidification device. An oxidizing agent solution is sprayed into the humidification device through the high-pressure pump in the form of mist and makes contact with waste gas introduced through the waste gas induced draught fan so that waste gas can enter the oxidation reaction system after being humidified. Ultraviolet lamps with the wavelength of 180-300 nm and a catalyst net are arranged in the oxidation reaction system. An atomized oxidizing agent cooperates with irradiation of ultraviolet light under the effect of the catalyst to generate a large amount of HO. and O3, and organic matter is degraded. The atomized oxidizing agent is introduced into an ultraviolet light catalysis reaction system, the oxidizing efficiency is greatly improved, and the oxidizing agent and ultraviolet light cooperating organic waste gas purification device has the advantages of being simple in structure, low in energy consumption and the like.

Description

technical field [0001] The invention relates to a device and a treatment method for purifying organic waste gas with oxidant and ultraviolet light, which can remove various volatile gaseous pollutants such as formaldehyde, toluene, ethylbenzene and xylene, and is suitable for treating low-concentration industrial volatile organic compounds (VOCs) , indoor air pollution, etc. Background technique [0002] In recent years, the advanced oxidation method induced by ultraviolet light has been widely used in environmental protection fields such as sewage treatment, waste gas treatment and so on. The photocatalytic oxidation of VOCs has become a research hotspot in this field. The principle is that through various oxidants or catalysts such as H 2 o 2 , Fenton's reagent, ozone, TiO 2 After absorbing ultraviolet light, HO is generated to initiate a series of free radical reactions to degrade pollutants. Compared with some developed countries abroad, although our country has a c...
