Description
본 발명은 디젤엔진에 설치되는 필터 재생장치에 관한 것으로, 특히 재생효율을 높이고 재생장치의 내구성을 증가시킬 수 있도록 된 디젤엔진의 필터 재생장치에 관한 것이다.The present invention relates to a filter regeneration device installed in a diesel engine, and more particularly, to a filter regeneration device of a diesel engine that is capable of increasing regeneration efficiency and increasing durability of the regeneration device.
디젤엔진에 설치되는 필터는 시간이 흐름에 따라 배기가스에서 배출되는 매연성분이 누적되게 되어 배압을 증가시키게 되므로 엔진의 출력을 감소시켜 기관의 성능을 저하시키는 하나의 원인이 되고 있다, 따라서, 일정한 시간이 경과되면 필터에 누적된 매연성분을 제거하는 재생과정을 거쳐야 한다.The filter installed in the diesel engine accumulates soot exhaust from the exhaust gas over time, and increases the back pressure, thus reducing the engine output and causing a decrease in engine performance. As time passes, the regeneration process removes the soot accumulated in the filter.
이를 위하여 종래에는 도 3에 도시된 것과 같은 장치를 사용하고 있다.For this purpose, the apparatus as shown in FIG. 3 is conventionally used.
즉, 필터(1)가 장착된 배기관(2)에 바이패스밸브(3)를 갖춘 바이패스관(4)이 설치되고, 상기 필터(1)의 앞쪽에는 진공펌프(5)와 진공스위치밸브(6)를 매개로 연결된 진공조절기(7) 및 트랩밸브(8)가 설치되어 있다.That is, the bypass pipe (4) having the bypass valve (3) is installed in the exhaust pipe (2) on which the filter (1) is mounted, and the vacuum pump (5) and the vacuum switch valve ( The vacuum regulator 7 and the trap valve 8 connected via 6) are provided.
그리고, 상기 필터(1) 일측에는 필터재생시 열을 공급하기 위한 히이터(9)가 장착되어 있다.On the one side of the filter 1, a heater 9 for supplying heat during filter regeneration is mounted.
따라서, 상기 트랩밸브(8)를 동작시켜 필터(1)로 들어가는 배기가스를 차단한 다음 바이패스밸브(3)를 동작시켜 바이패스관(4)을 개방하면 엔진으로부터 나오는 배기가스가 바이패스관(4)을 통해 배출되게 되고, 이와 동시에 상기 히이터(9)를 동작시키면 히이터(9)에서 발산되는 열로 인해 필터(1)에 누적된 매연성분을 태우게 됨으로써 필터를 재생시키도록 구성되어 있다.Therefore, when the trap valve 8 is operated to block the exhaust gas entering the filter 1, and then the bypass valve 3 is operated to open the bypass pipe 4, the exhaust gas from the engine is bypassed. It is discharged through (4), and at the same time operating the heater (9) is configured to regenerate the filter by burning the soot components accumulated in the filter (1) due to the heat emitted from the heater (9).
그런데 이상과 같이 구성된 종래의 재생장치는 히이터(9)에서 발산되는 고온의 열로 인해 장치 전체에 무리가 가게 되어 재생효율을 저하시킬 뿐 아니라, 오히려 필터가 손상되게 되어 살용화시키기에는 무리가 있다는 문제가 있다.By the way, the conventional regeneration apparatus configured as described above has a problem that the whole regeneration of the apparatus due to the high temperature heat emitted from the heater 9 not only lowers the regeneration efficiency, but also causes the filter to be damaged and makes it difficult to make use of it. There is.
이에 본 발명은 상기와 같은 문제를 감안하여 발명된 것으로, 재생시 외기를 유입시켜 재생효율을 향상시키고, 보호유리를 장착시켜 재생장치가 열에 노출되는 것을 최대한 방지함으로써 내구성을 증가시킬 수 있도록 된 디젤엔진의 필터 재생장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been invented in view of the above problems, and it is possible to increase the durability by introducing external air during regeneration to improve regeneration efficiency, and by installing a protective glass to prevent the regeneration apparatus from being exposed to heat to the maximum. It is an object to provide a filter regeneration device for an engine.
상기와 같은 목적을 달성하기 위한 본 발명은, 필터가 장착된 배기관에 바이패스관이 설치되고, 상기 필터의 앞쪽에는 진공펌프와 진공스위치밸브를 매개로 연결된 진공조절기와 트랩밸브가 설치된 디젤엔진의 필터 재생장치에 있어서, 상기 필터 앞쪽에 진공조절기와 연결된 공기공급밸브가 설치되고, 필터 일측에는 보호유리가 부착되어 있다.The present invention for achieving the above object, the bypass pipe is installed in the exhaust pipe is equipped with a filter, the front of the filter of the diesel engine is installed with a vacuum regulator and a trap valve connected via a vacuum pump and a vacuum switch valve In the filter regeneration device, an air supply valve connected to a vacuum regulator is installed in front of the filter, and a protective glass is attached to one side of the filter.

이하 본 발명의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명에 따른 필터 재생장치의 개략 구성도로써, 동래 사용구조와 동일 부위에는 동일 참조부호가 도시되어 있는 바, 본 발명은 도면에 도시된 것과 같이, 필터(1)가 장착된 배기관(2)에 바이패스밸브(3)를 갖춘 바이패스관(4)이 설치되고, 상기 필터(1)의 앞쪽에는 진공펌프(5)와 진공스위치밸브(6)를 매개로 연결된 진공조절기(7)와 트랩밸브(8)가 설치되며, 상기 필터(1)의 앞쪽에는진공조절기(7)와 연결된 공기공급밸브(10)가 설치되어 있다.1 is a schematic configuration diagram of a filter regeneration device according to the present invention, in which the same reference numerals are shown at the same site as the structure used in the present invention, as shown in the drawing. A bypass pipe 4 having a bypass valve 3 is installed in the filter 2, and a vacuum regulator 7 connected to the front of the filter 1 via a vacuum pump 5 and a vacuum switch valve 6 is provided. ) And a trap valve 8, and an air supply valve 10 connected to the vacuum regulator 7 is installed at the front of the filter 1.
그리고, 상기 필터(1) 일측에는 필터재생시 열을 공급하기 위한 히이터(9)가 장착되고, 이 주변에는 디젤배기가스의 미립(Particulate)으로부터 재생장치를 보호할 수 있도록 보호유리(11)가 부착되어 있다.One side of the filter 1 is equipped with a heater 9 for supplying heat during filter regeneration, and a protective glass 11 is provided around the filter 1 to protect the regeneration device from particulates of diesel exhaust gas. Attached.
따라서, 상기 트랩밸브(8)를 동작시켜 필터(1)로 들어가는 배기가스를 차단한 다음 바이패스밸브(3)를 동작시켜 바이패스관(4)을 개방하면 엔진으로부터 나오는 배기가스가 바이패스관(4)을 통해 배출되게 되고, 이와 동시에 상기 히이터(9)를 동작시키면 히이터(9)에서 발산되는 열로 인해 필터(1)에 누적된 매연성분을 태우게 됨으로써 필터를 재생시키게 된다.Therefore, when the trap valve 8 is operated to block the exhaust gas entering the filter 1, and then the bypass valve 3 is operated to open the bypass pipe 4, the exhaust gas from the engine is bypassed. At the same time, when the heater 9 is operated, the smoke component accumulated in the filter 1 is burned by the heat emitted from the heater 9, thereby regenerating the filter.
그리고, 상기 히이터(9) 동작시 공기공급밸브(10)를 온시키면 외기가 밸브를 타고 히이터(9)로 자연스럽게 유입되게 되는데, 이때 산소는 대류에 의해 필터(1)내부로 공급되게 되므로 필터표면에 퇴적된 여러 유해성분을 완전하게 연소시킬 수 있게 된다.When the air supply valve 10 is turned on during the operation of the heater 9, outside air naturally flows into the heater 9 through the valve, and oxygen is supplied into the filter 1 by convection. It is possible to completely burn various harmful components deposited in the furnace.
또한, 재생을 위해 히이터(9)를 동작시켜도 그 주위에 설치된 보호유리(11)가 이를 차단시키게 되므로 디젤배기가스의 미립으로부터 재생장치를 보호할 수 있게 된다.In addition, even when the heater 9 is operated for regeneration, the protective glass 11 installed thereon blocks the regeneration device, thereby protecting the regeneration device from particulates of the diesel exhaust gas.
한편, 본 발명에 의한 재생장치로 필터를 재생한 결과 도 3에 도시된 것과 같이 외기를 유입시키지 않은 조건에서 재생을 한 것보다 상대적으로 높은 재생율을 얻을 수 있었다.On the other hand, as a result of regenerating the filter by the regeneration device according to the present invention, as shown in FIG.
이상 설명한 바와 같이 본 발명은 재생시 외기를 유입시켜 재생효율을 향상시키고, 보호유리를 장착시켜 재생장치가 열에 노출되는 것을 최대한 방지함으로써 내구성을 증가시킬 수 있는 잇점이 있다.As described above, the present invention has an advantage of increasing durability by introducing external air during regeneration to improve regeneration efficiency and preventing the regeneration apparatus from being exposed to heat by mounting a protective glass.
