Working principle of fish meal odor treatment equipment

The foul odor gas generated during the fish meal processing has a complex chemical composition and is related to the freshness of the raw materials. According to the current situation of industry governance, there is currently no comprehensive analysis data on its composition. According to our investigation and reference to relevant information, it is found that the foul odor gas in the fish meal processing is mainly formed by substances such as acrolein, oil degradation products, hydrogen sulfide, ammonia, butyric acid and valeric acid, as well as trimethylamine. For the human body's sense of smell, it cannot accept this odor, which can cause discomfort and directly affect the production efficiency of employees. At the same time, it can also affect the corporate image and bring intangible economic losses. Therefore, when producing fish meal, it is necessary to use fish meal odor treatment equipment. So, what is the working principle of this equipment?

Photocatalytic oxidation occurs under the action of visible light from the outside world, using semiconductors and air as catalysts and light as energy to degrade organic matter into CO2, H2O, and other non-toxic and harmless components. Our company uses artificial ultraviolet light waves as energy, combined with our specially treated nano TiO2 catalyst, which has the strongest activity and highest reaction efficiency. After treatment, the waste odorous gas can achieve a more ideal purification effect.

In the semiconductor photocatalytic oxidation reaction, ultraviolet light is irradiated on the nano TiO2 catalyst. The nano TiO2 catalyst absorbs light energy and produces electron hole transitions. After further combination, electron hole pairs are generated, which react with the adsorbed water (H2O) and oxygen (O2) on the exhaust gas surface to generate oxidizing active wave free radicals and superoxide ion free radicals. It can reduce various organic waste gases such as hydrocarbons, aldehydes, phenols, alcohols, thiols, benzene, ammonia, nitrogen oxides, sulfides, and other VOC organic and inorganic substances under photocatalytic oxidation to carbon dioxide (CO2), water (H2O), and other non-toxic and harmless substances. After purification, the waste gas molecules are activated and degraded, and the odor also disappears, playing a role in waste gas purification, At the same time, bacteria that grow inside the pipeline can be effectively removed. Due to the absence of any additives in the photocatalytic oxidation process, there will be no secondary pollution. In terms of operating costs, only electrical energy is used without the need for frequent replacement of accessories, which is quite energy-saving and environmentally friendly for enterprises.
