1Cable factory exhaust gas treatment equipment | Photocatalytic oxidation cable factory exhaust gas treatmentTechnical principle:

1. Photocatalytic oxidation is a catalytic reaction that occurs under the action of visible light from the outside. The photocatalytic oxidation reaction uses semiconductors and air as catalysts, and light as energy to degrade organic matter into CO2 and H2O. The semiconductor used by our company is the current reaction efficiency nano TiO2 photocatalyst, which has been specially treated and used to achieve the desired effect.

2. In photocatalytic oxidation reactions, electron hole pairs are generated on nano TiO2 photocatalysts by ultraviolet light irradiation, which react with adsorbed water (H2O) and oxygen (O2) on the surface to generate highly reactive hydroxyl radicals (OH -) and superoxide ion radicals (O2-, 0-). It can reduce various waste odorous gases such as aldehydes, benzene, ammonia, nitrogen oxides, sulfides, and other VOC organic and inorganic substances to carbon dioxide (CO2), water (H2O), and other non-toxic and harmless substances under the action of photocatalytic oxidation. At the same time, it has the effects of deodorization, disinfection, and sterilization. Since there are no additives in the photocatalytic oxidation reaction process, it will not produce secondary pollution.

(1) Photocatalytic oxidation is suitable for completely oxidizing waste odorous gases into non-toxic and harmless substances at room temperature, and is suitable for treating toxic and harmful gases with high concentration, large gas volume, and strong stability.

(2) Effective purification: Through photocatalytic oxidation, waste odorous gases in the air can be completely oxidized into non-toxic and harmless substances without leaving any secondary pollution.

(3) Green energy: Photocatalytic oxidation uses vacuum wave ultraviolet light generated by artificial ultraviolet lamps as energy to activate photocatalysts and drive oxidation-reduction reactions. Moreover, photocatalysts are not consumed during the reaction process, and the use of oxygen in the air as an oxidant effectively degrades toxic and harmful waste gases, becoming the energy-saving feature of photocatalysis.

(4) Strong oxidizing property: Semiconductor photocatalysis has the characteristic of strong oxidizing property, which can effectively decompose certain organic compounds that are difficult to oxidize by ozone, such as chloroform, carbon tetrachloride, and hexachlorobenzene. Therefore, it has special significance for organic compounds that are difficult to degrade. The effective oxidants for photocatalysis are hydroxyl radicals (OH -) and superoxide ion radicals (O2-, 0-), which have higher oxidizing property than common ozone, hydrogen peroxide, potassium permanganate, hypochlorous acid, etc.

(5) Photocatalytic oxidation is effective for a wide range of organic compounds, from hydrocarbons to carboxylic acids. Even for atomic organic compounds such as halogenated hydrocarbons, dyes, nitrogen-containing organic compounds, and organophosphorus insecticides, it has a good removal effect. With a certain amount of reaction time, complete purification can be achieved.

(6) Long lifespan: In theory, the lifespan of photocatalysts is infinite and does not require replacement.
