PURPOSE: An SCR system is provided to remove contaminated components of exhaust gas with simple structure while preventing destruction and damages of the SCR system due to vibration and external shock while reducing volume of a catalyst. CONSTITUTION: An SCR system connected to an exhaust gas facility(1) includes the following: an SCR reactor(2) having a front pipe and a back pipe with a catalyst activated by exhaust gas; a reducing agent supply line supplying a reducing agent to the SCR reactor; a sensor(11) detecting remaining contaminants in the exhaust gas and is equipped on the rear end of the SCR reactor; an analyzer(7) analyzing remaining contaminants by using information gained from the sensor; and a water spray part(20) removing the contaminants in the exhaust gas. |
