Description

technical field [0001] The invention relates to the technical field of automobile exhaust catalysts, in particular to a device for extracting precious metals from automobile exhaust catalysts. Background technique [0002] Due to the unique purification ability of platinum group metals on automobile exhaust, more than 60% of platinum and palladium are used in the production of automobile exhaust purification catalysts every year. Although many devices are researching new catalysts to replace or reduce the use of platinum group metals, the demand for platinum group metals will further increase with the increase in the number of cars and the improvement of environmental protection standards. Because platinum group metal resources are scarce and expensive, and platinum group metals in auto catalysts are a "recyclable platinum mine", it is very important to recover platinum group metals from spent automobile exhaust catalysts. [0003] During the use of the existing precious me...
