| titleOfInvention | Selective Catalytic Reduction System and Reactor Regeneration Control Method Thereof |
| abstract | The present invention relates to an SCR system and a method for controlling regeneration of a reactor thereof. The present invention is an SCR system for removing nitrogen oxides from engine exhaust gas by an SCR reactor, which is installed at the rear end of the SCR reactor to detect the concentration of ammonia generated during the reactor regeneration treatment to remove ammonium disulfate of the SCR reactor. A detection sensor for applying the detected ammonia concentration to the controller; It provides an SCR system comprising a controller for performing a reactor regeneration process while monitoring the removal state of the ammonium disulfate based on the ammonia concentration detected by the detection sensor. According to the present invention, the temperature of the engine exhaust gas is raised to the possible reaction temperature in the SCR reactor, and ammonia decomposed from urea is mixed with the engine exhaust gas as a reducing agent and introduced into the SCR reactor. When the SCR reactor is regenerated by removing contamination of the SCR reactor due to ammonium disulfate generated in the SCR reactor as the exhaust gas purification treatment to remove nitrogen oxides proceeds, the removal status of ammonium disulfate is monitored and the SCR By accurately grasping the completion point of regeneration of the reactor, the SCR reactor is regenerated by sufficiently removing ammonium disulfate in the SCR reactor, thereby stably performing the purification treatment of engine exhaust gas. |
