In recent years, with the rapid development of science and technology, the continuous improvement of human living standard and the continuous expansion of industrial production scale, the problem of environmental pollution is increasingly serious, wherein the atmospheric environmental pollution on which human beings live is not optimistic, and the waste gas generated in industrial production is an important contribution source of atmospheric pollution, so that the effective control and treatment of the waste gas generated in industrial production become an important task of atmospheric treatment in China at present.
Because the components in the industrial waste gas are complex and the ideal treatment effect cannot be achieved by using a single oxidation process, in practical application, a plurality of oxidation processes are often combined to generate more hydroxyl radicals (. OH) and O3Thereby improving the oxidative degradation capability of the treatment system to the exhaust gas. Among various advanced oxidation technologies, ozone oxidation and photocatalytic oxidation have been widely applied in the field of exhaust gas engineering treatment, but have respective limitations. Therefore, two technologies of photocatalytic oxidation and ozone oxidation are combined, on one hand, ozone can be used as an electron capture agent, the recombination of holes and electrons is reduced, and the photocatalytic efficiency is improved; on the other hand, photocatalysis can also strengthen the oxidative degradation reaction of ozone on organic matters, and improve the utilization efficiency of ozone molecules. Therefore, the photocatalysis-ozone oxidation technology is combined for use, and the synergistic degradation of the waste gas is a promising treatment technology.
In the research and engineering application of ozone photocatalytic treatment of difficultly-degradable waste gas, the key of the design of the treatment device is the continuous high-efficiency treatment of the waste gas with low energy consumption, but the existing conventional engineering ozone photocatalytic treatment device does not consider the full mixing of an external ozone source and the waste gas due to the design reason, has a certain oxidation treatment effect in the process, forms relatively stable waste gas concentration and is beneficial to the next degradation; in the process that the ultraviolet lamp tube is directly exposed to the waste gas flow, certain crystals are gradually formed after oxidation and decomposition and are adsorbed outside the ultraviolet lamp tube, the energy of ultraviolet photons is slowly shielded, the treatment efficiency of the waste gas is reduced, and even if the device is detached, the ultraviolet lamp tube is time-consuming and labor-consuming to clean one by one and is easy to damage; the contact area of the photocatalytic plate is insufficient, so that the efficiency of waste gas treatment is influenced; after the waste gas is oxidized by the external ozone source, the residual ozone in the tail gas is not treated, so that the environmental pollution is easily caused.
