[0011] Example 1: Purification of waste gas containing toluene.
[0012] A schematic diagram of the structure of a photo-oxidation coupled catalytic ozone oxidation air purifier figure 1 As shown, it includes a filter layer 1, a fan 2, a duct system 3, a housing 4, a wavelength ≤185nm ultraviolet lamp 5, a wavelength ≤254nm ultraviolet lamp 6, a fan 7, a catalyst 8, a fan 9, and a purified air 10. Taking toluene-containing organic waste gas as an example, the toluene-containing organic waste gas is subjected to the dust removal and purification of the filter layer 1 under the action of the fan 2, and then enters the pipeline system 3 with the wavelength ≤185nm ultraviolet lamp 5 and the wavelength ≤254nm ultraviolet lamp 6. Photo-oxidation, the organic waste gas containing toluene is oxidized into harmless carbon dioxide and water. The undegraded toluene and part of ozone reach the catalyst 8 through the blower 7. After catalytic ozone oxidation, the toluene and ozone are complete...
