SELECTIVE CATALYTIC REDUCTION REACTOR WITH IMPROVED STRUCTURE

摘要

The present invention relates to a selective catalytic reduction reactor capable of reducing exhaust gas into nitrogen and water vapor. The provided selective catalytic reduction reactor having an improved structure includes: a housing having an exhaust gas inlet and an exhaust gas outlet; a catalyst installed inside the housing; a heater installed on the outside of the housing and having an air inlet and an air outlet; and a reductant decomposition chamber having a reductant inlet for introducing air heated by the heater and a reductant, and a reductant outlet disposed adjacent to the exhaust gas inlet and jetting the reductant into the housing.
