The water scrubber 10 is configured to absorb water-soluble pollutants and part of dust in the exhaust gas; the absorption tower 20 is configured to remove sulfides and nitrogen oxides in the exhaust gas by spraying an alkaline solution, and the water scrubber 10 and the absorption tower 20 generate a certain amount of sewage after the exhaust gas is treated, and the sewage is collected and intensively treated by the above-mentioned sewage collecting device. The above-described photocatalytic device 30 is configured to remove organic exhaust gas from exhaust gas using ultraviolet rays and a photocatalyst. The photocatalyst absorbs light energy to generate electron leap-in and hole leap-in through ultraviolet light irradiation on the photocatalyst, an electron-hole pair is generated through further combination, and the electron-hole pair reacts with the waste gas and moisture and oxygen in the air introduced by the blast system 40 to generate hydroxyl free radicals and superoxide ion free radicals with strong oxidizability, so that various organic waste gases such as aldehydes, benzenes, ammonia, methanol, hydrocarbons, carbon monoxide and other VOC organic matters are reduced into carbon dioxide, water and other nontoxic and harmless substances under the action of photocatalytic oxidation.
Specifically, in the present embodiment, the photocatalytic device 30 includes a base 31; the substrate 31 has an air inlet end and an air outlet end opposite to each other; the air inlet end is respectively connected with one end of the demister 21 far away from the absorption tower 20 and the air blowing system 40; the substrate 31 comprises a filtering device 33, a reaction channel 34 and an ultraviolet generator 32; the filtering device 33 is arranged in the base body 31 near the air inlet end; the ultraviolet generator 32 is arranged along the length direction of the substrate 31; the reaction channel 34 is surrounded by the ultraviolet generator 32, and the photocatalyst is arranged on the inner wall of the reaction channel 34.
