녹스를 정화하기 위하여 일반적으로 SCR 모듈이 많이 사용된다. 그러나 SCR 모듈의 성능 및 수명은 촉매의 피독(Posion) 물질인 황에 의해 훼손된다. 즉 배기가스 중에 함유된 녹스는 SCR 모듈에서 제거되지만 황이 SCR 모듈에 흡착될 경우 SCR 모듈의 성능 및 수명이 훼손된다. 그래서 SCR 모듈을 장시간 사용하면 SCR 모듈에 황피독이 발생하여 SCR 모듈이 제기능을 발휘하지 못하고 수명이 다한다는 문제점이 발생한다.SCR modules are commonly used to purify rusty. However, the performance and longevity of the SCR module are compromised by sulfur, the poison material of the catalyst. In other words, the rust contained in the exhaust gas is removed from the SCR module, but if sulfur is adsorbed to the SCR module, the performance and lifespan of the SCR module is impaired. Therefore, if the SCR module is used for a long time, the poisoning occurs in the SCR module, which causes a problem that the SCR module does not function properly and reaches its end of life.

도 1 내지 도 4를 참조하여 본 발명에 따른 SCR 모듈 재생장치의 일 실시예를 설명한다.An embodiment of an SCR module playback apparatus according to the present invention will be described with reference to FIGS.
본 발명에 따른 SCR 모듈 재생장치는 모듈함(10)과, 이동수단(15)과, 공기통로(20)와, 순환팬(25)과, 가열기(30)를 포함한다.The SCR module reproducing apparatus according to the present invention includes a module box 10, a moving means 15, an air passage 20, a circulation fan 25, and a heater 30.
모듈함(10)은 내부에 SCR 모듈을 수용할 수 있으며, 일측(12)에서 타측(13)으로 공기가 유동될 수 있도록 일측(12)과 타측(13)이 개방된다. 그리고 모듈함(10)은 단열을 위하여 보온재(11)로 감싸진다. 본 실시예의 경우 모듈함(10)은 2개가 구비된다. 그래서 2개의 모듈함(10)에 SCR 모듈을 각각 수용시킬 수 있다.The module box 10 may accommodate the SCR module therein, and one side 12 and the other side 13 are opened to allow air to flow from one side 12 to the other side 13. And the module box 10 is wrapped with a heat insulating material (11) for insulation. In the present embodiment, two module boxes 10 are provided. Thus, the SCR modules can be accommodated in two module boxes 10, respectively.
이동수단(15)은 연결통로(16)와 바퀴(17)를 구비한다. 이동수단은 모듈함(10)을 거치시켜서 모듈함(10)을 이동시키는 역할을 한다. 이를 위하여 바퀴(17)는 이동수단(15)의 하부에 형성되며, 이동수단(15)의 상부에 모듈함(10)이 거치된다. 그리고 연결통로(16)는 모듈함(10)이 상부에 거치된 경우 모듈함(10)의 일측(12)과 연결되도록 형성된다. 그래서 모듈함(10)의 타측(13)에서부터 연결통로(16) 까지 공기가 유동될 수 있다. 본 실시예의 경우 모듈함(10)이 2개 구비되므로 각각의 모듈함(10)을 이동시키기 위하여 이동수단(15)도 2개 구비된다.The moving means 15 has a connecting passage 16 and a wheel 17. The moving means serves to move the module box 10 by mounting the module box (10). To this end, the wheel 17 is formed in the lower portion of the moving means 15, the module box 10 is mounted on the upper portion of the moving means (15). And the connecting passage 16 is formed to be connected to one side 12 of the module box 10 when the module box 10 is mounted on the top. Thus, air may flow from the other side 13 of the module box 10 to the connection passage 16. In the present embodiment, since two module boxes 10 are provided, two moving means 15 are also provided to move each module box 10.
공기통로(20)는 모듈함(10) 내부로 공기를 순환시키는 통로로서, 이를 위하여 일단(21)은 연결통로(16)에 연결이 가능하고, 타단(22)은 모듈함(10)의 타측(13)에 연결이 가능하다. 본 실시예의 경우 이동수단(15)과 모듈함(10)이 각각 2개씩 구비되어 있으므로, 공기통로(20)의 일단(21)과 타단(22)도 각각의 연결통로(16)와 모듈함(10)의 타측(13)에 연결되기 위하여 분기되어 2개로 형성된다. 그리고 공기통로(20)의 일단(21)과 타단(22)에는 개폐댐퍼(23)가 설치되어 공기통로(20)를 개폐시킬 수 있다. Air passage 20 is a passage for circulating air into the module box 10, one end 21 can be connected to the connecting passage 16 for this purpose, the other end 22 is the other side of the module box 10 It is possible to connect to (13). In this embodiment, since the moving means 15 and two module boxes 10 are provided, respectively, one end 21 and the other end 22 of the air passage 20 are also connected to the respective connecting passages 16 and the module box ( Branched to be connected to the other side 13 of 10) is formed in two. One end 21 and the other end 22 of the air passage 20 may be provided with an opening / closing damper 23 to open and close the air passage 20.
순환팬(25)은 공기통로(20)를 따라 공기가 순환될 수 있도록 공기통로(20)에 설치된다.The circulation fan 25 is installed in the air passage 20 so that air can be circulated along the air passage 20.
가열기(30)는 모듈함(10)에 수용된 SCR 모듈에 흡착된 황을 제거할하기 위하여 공기통로(20)를 따라 순환되는 공기를 가열시킬 수 있도록 공기통로(20)에 설치된다.The heater 30 is installed in the air passage 20 to heat the air circulated along the air passage 20 to remove the sulfur adsorbed to the SCR module accommodated in the module box 10.
SCR 모듈은 SCR 시스템에서 사용된다. SCR 시스템에서 사용된 SCR 모듈에 황이 흡착되어 성능이 저하된 경우 이동수단(15)의 상부에 모듈함(10)을 거친 시킨 다. 이동수단(15)의 상부에 거치된 모듈함(10)의 일측(12)은 연결통로(16)여 연결된다. 그리고 이동수단(15)을 SCR 시스템으로 이동시키고, SCR 시스템에서 황피독된 SCR 모듈을 꺼내어 이동수단(15)의 모듈함(10)에 저장시킨다. 모듈함(10)에 SCR 모듈이 저장된 경우 이동수단(15)을 이동시켜서 이동수단(15)의 연결통로(16)를 공기통로(20)의 일단(21)에 연결시킨다. 그리고 공기통로(20)의 타단(22)을 모듈함(10)의 타측(13)에 연결시킨다. SCR modules are used in SCR systems. When sulfur is adsorbed on the SCR module used in the SCR system and the performance is degraded, the module box 10 is roughened on the upper portion of the moving means 15. One side 12 of the module box 10 mounted on the upper portion of the moving means 15 is connected by a connection passage (16). Then, the moving means 15 is moved to the SCR system, and the toxic poisoned SCR module is taken out of the SCR system and stored in the module box 10 of the moving means 15. When the SCR module is stored in the module box 10, the moving means 15 is moved to connect the connection passage 16 of the moving means 15 to one end 21 of the air passage 20. The other end 22 of the air passage 20 is connected to the other side 13 of the module box 10.
가열기(30)를 사용하여 공기를 가열시키고, 순환팬(25)을 사용하여 가열된 공기를 순환시키면 가열된 공기는 모듈함(10)으로 공급되어 공기통로(20)를 통하여 순환된다. 모듈함(10)에 수용된 SCR 모듈에 흡착된 황은 가열 공기에 의하여 제거된다.When the air is heated using the heater 30 and the heated air is circulated using the circulation fan 25, the heated air is supplied to the module box 10 and circulated through the air passage 20. Sulfur adsorbed to the SCR module housed in the module box 10 is removed by heating air.
2개의 모듈함(10)이 모두 공기통로(20)에 연결된 경우 개폐댐퍼(23)를 모두 개방시켜서 공기가 모듈함(10) 모두에 순환되도록 하지만, 어느 하나의 모듈함(10) 만이 공기통로(20)에 연결된 경우 연결되지 아니한 곳의 개폐댐퍼(23)를 폐쇄시킨다.When both module boxes 10 are connected to the air passage 20, the open / close dampers 23 are all opened to allow air to circulate through all of the module boxes 10, but only one module box 10 passes through the air passage. If it is connected to (20) closes the opening and closing damper (23) where it is not connected.
따라서 본 실시예에 의하면 SCR 모듈에 흡착된 황을 제거할 수 있어서, SCR 모듈을 재생시킬 수 있다.Therefore, according to this embodiment, sulfur adsorbed on the SCR module can be removed, and the SCR module can be regenerated.
