Agent is the ceramic honey comb for being coated with precious metal palladium and platinum, and the mass ratio of palladium and platinum is 3:7；Catalysis at 500 DEG C of the second level
Burning, used catalyst is the ceramic honey comb for being coated with precious metal palladium and platinum, and the mass ratio of palladium and platinum is 6:4；The third level 300
Catalysis burning at DEG C, used catalyst is the ceramic honey comb for being coated with precious metal palladium and platinum, and the mass ratio of palladium and platinum is 8:
2.Such temperature setting and the pro rate of noble metal catalyst palladium and platinum have been fully taken into account per one-level catalyst combustion reaction
Demand, the harmful exhaust amount in catalyticing combustion process at 650 DEG C of the first order is larger, and required reaction temperature is higher, due to expensive
Metal platinum remaining at high operating temperatures keeps good catalytic effect, so the present invention use metal platinum as starting burning instead
The catalyst answered, is then used as supplement catalyst using the relatively low palladium of price；In subordinate's catalyst combustion reaction reduction catalytic temperature
Meanwhile, step up the ratio of palladium so that waste gas is reaching highest reactivity simultaneously, reduces the use cost of catalyst.
The combination of said temperature and the determination of catalyst ratio, are that the present inventor obtains by studying, testing repeatedly, summarize
Optimum combination.
Enameling machine oven waste gas tail gas multiple treatment device is main by baker 10, two grades of catalyst containers 11 and three-level catalyst container 12
Composition.
