Vacuum carburizing harmful exhaust gase reducction apparatus and vacuum carburizing harmful exhaust gase reducction method using the same

Abstract

The present invention relates a vacuum carburizing harmful exhaust gas reduction apparatus and vacuum carburizing harmful exhaust gas reduction method using the same. vacuum carburizing harmful exhaust gas reduction apparatus includes a high-temperature decomposition unit configured to heat exhaust gases discharged from a vacuum pump in the vacuum carburizing process to a temperature ranging from 500 to 1500° C., and a high-temperature catalyst unit comprising a supported catalyst supporting a catalyst including one or more selected from a group including platinum (Pt), palladium (Pd), and alloys thereof and configured to allow the exhaust gases heated in the high-temperature decomposition unit to contact the supported catalyst. According to the present invention, it is possible to significantly reduce harmful substances such as carbon monoxide, nitrogen oxides, benzene, and total hydrocarbons (THC) in the exhaust gases expelled by the vacuum pump during the vacuum carburizing process.
