Description

Technical Field

[0001] This utility model relates to the field of waste catalyst recycling technology, and in particular to a continuous iron removal device for waste ozone deoxidation catalyst. Background Technology

[0002] The recycling of spent catalysts is of great significance for environmental protection and resource reuse. These catalysts are widely used in petrochemical, pharmaceutical manufacturing, and automotive exhaust purification industries. During use, they gradually deactivate and accumulate impurities. If not properly disposed of after disposal, they may cause heavy metal pollution to soil and water bodies. Therefore, recycling precious metals (such as platinum and palladium) and rare earth elements from spent catalysts can not only alleviate resource shortages but also effectively reduce the risk of environmental pollution.

[0003] The main components of ozone desiccant catalysts include various transition metal oxides and precious metals, such as manganese dioxide, iron tetroxide, and platinum (Pt), palladium (Pd), and silver (Ag). These metals play a crucial role in the catalyst, significantly improving ozone utilization and degradation capacity, especially exhibiting extremely high catalytic activity at low temperatures. In catalyst recovery processes, iron removal is a critical step determining regeneration quality. Iron, a common impurity element in catalysts, directly affects the activity and lifespan of the regenerated catalyst. Iron in spent catalysts can be separated using physical and chemical methods. Physical methods mainly employ techniques such as magnetic separation and sieving, utilizing the magnetic or density differences between iron and other components to achieve separation. Chemical methods involve reactions such as acid leaching and complexation to convert iron into soluble compounds for extraction.

[0004] The main method for removing iron from catalysts is to first remove elemental iron. This involves crushing honeycomb or plate-shaped catalysts. After crushing, the elemental iron inside the crushed catalyst needs to be separated through methods such as filtration and magnetic separation before chemical iron removal. However, current technology requires crushing the catalyst first and then collecting it for iron removal. This process is quite complex, and during transportation, the poor stability of the crushed catalyst can cause environmental pollution and catalyst loss. Utility Model Content
