Description

Technical Field

[0001] The utility model relates to the technical field of tail gas treatment, in particular to an ozone catalytic oxidation tail gas recovery device. Background Art

[0002] As a practical and efficient advanced oxidation technology, ozone oxidation has the advantages of strong processing capacity, high degree of automation, no secondary pollution, and simple equipment. It has broad application potential in the treatment of various industrial wastewaters, especially in the field of deep sewage treatment. The gas produced after ozone treatment still contains a small amount of ozone, and direct discharge will have an adverse effect on the surrounding air environment. Therefore, the ozone oxidation tail gas needs to be recovered and treated.

[0003] The core of ozone catalytic oxidation exhaust gas recovery technology lies in the efficient utilization of ozone catalysts. These catalysts demonstrate excellent performance in promoting ozone decomposition, with the primary decomposition product being highly reactive hydroxyl radicals (OH·). These radicals possess strong oxidative power and react rapidly with organic matter in the exhaust gas, effectively degrading pollutants. However, if the exhaust gas does not spend sufficient contact time with the ozone catalyst as it passes through it, this can limit the full decomposition of ozone, resulting in residual, incompletely treated ozone in the exhaust gas.
