The invention discloses a labyrinth roasting and carbonizing system for waste catalysts. The labyrinth roasting and carbonizing system comprises a labyrinth roasting and carbonizing furnace main body, an auxiliary heating combustion device, an automatic discharging device and a three-stage high-temperature oxidizing chamber. The labyrinth roasting and carbonizing system for the waste catalysts has the advantages that a labyrinth roasting and carbonizing furnace for the waste catalysts and the three-stage high-temperature oxidizing chamber are in integrated temperature control, so that safety roasting and carbonizing of the waste catalysts are guaranteed while own heat of the waste catalysts is stimulated completely, operation cost is reduced through a whole treatment technology, precious metals cannot lose due to interference of strong airflow during roasting and carbonizing, and reduction, harmlessness, recycling and equipment operation safety are achieved.
Description
technical field [0001] The invention relates to a labyrinth roasting and carbonization system for spent catalysts. Background technique [0002] The waste catalyst vertical roasting and carbonization furnace involves: the roasting of waste catalysts containing platinum and palladium on the alumina carrier after adsorption and saturation in the chemical industry, medicine, and petroleum industries. The materials are: φ1.5-3.5mm spherical particles and φ(1.5- 2.5) x (2.5-10) mm thin columnar two kinds, the raw material contains organic matter ≤ 20% (the average value is 15%), the water content is 2.5-7.5% (the average value is 5%), and the bulk density of the material is 0.5t / m 3 . Due to the late start of the recovery of waste catalyst regeneration resources in my country, the technology is relatively lagging behind, the recycling production is extensively operated, the recycling units are scattered, and the scale cannot be formed; moreover, the recycling equipment is simple...
