STERILISER WITH EXHAUST GAS CLEANING SYSTEM FOR DECOMPOSING NOX WITH OZONE

摘要

An exhaust system is provided for exhausting an exhaust gas used for sterilizing an item to be sterilized by using a high concentration NO2 gas, including an ozone generator, a gas treatment means for adsorbing ozone generated by the ozone generator and NO2 in the exhaust gas and accelerating generation of dinitrogen pentoxide or nitric acid by a reaction of the ozone and NO2 to retain the resultant, and an exhaust apparatus for exhausting the exhaust gas. The exhaust system can effectively and ably purify a high concentration NO2 exhaust gas having a concentration beyond the normal level.
