본 고안은 배기가스 재순환 정화 처리장치에 관한 것이다.The present invention relates to an exhaust gas recycle purification treatment apparatus.
엔진으로부터 연소된 배기가스는 배기매니폴드와 배기파이프를 거쳐 외부로 배출되어진다.The exhaust gas combusted from the engine is discharged to the outside via the exhaust manifold and the exhaust pipe.
그런데 배기가스중에는 CO, HC, NOx 등 유해가스가 많이 포함되어 있어 이를 그대로 대기로 방출하게 될 경우 환경오염을 유발하게 되므로 이들 유해가스를 산화 한원 반응에 의하여 각기 무해한 CO2, H2O, N2로 정화 처리하여 배출하기 위한 촉매 변환기를 배기파이프의 도중에 설치하고 있다.However, the exhaust gas contains a lot of harmful gases such as CO, HC, NOx, and if released to the atmosphere as it will cause environmental pollution, these harmful gases are each harmless CO 2 , H 2 O, N A catalytic converter for purifying and discharging the furnace 2 is installed in the middle of the exhaust pipe.
그러나 종래의 경우 일단 배기가스가 촉매변환기를 통과하게 되면 정화처리가 충분히 이루어지지 아니한 상태라 하더라도 대기로 그대로 방출하게 되므로써 환경 오염의 원인이 되고 있으며 정화의 완벽성을 추구하기 위하여 값비싼 촉매변환기를 복수개 설치하는 것도 경제성 및 레이아웃상 곤란하다는 문제점이 있었다.However, in the conventional case, once the exhaust gas passes through the catalytic converter, even if the purification process is not sufficiently performed, the exhaust gas is emitted to the atmosphere, thereby causing environmental pollution. There is also a problem that it is difficult in terms of economics and layout to install a plurality.
이에 본 고안은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는 것은 촉매변환기를 통과한 배기가스를 다시 재순환시켜 정화처리 하므로써 정화 효율을 높여 환경오염을 예방하는 배기가스 재순환 정화 처리장치를 제공하는데 있다.Therefore, the present invention has been proposed in view of the above problems, and its object is to provide an exhaust gas recirculation purification treatment apparatus which improves the purification efficiency by preventing the pollution by recirculating the exhaust gas passed through the catalytic converter again. have.

이하 본 고안의 구성과 작용을 첨부한 도면을 참조하여 설명한다.Hereinafter, with reference to the accompanying drawings the configuration and operation of the present invention.
도 1은 본 고안에 의한 배기가스 재순환 정화 처리장치를 나타내는 도면으로 도면중 부호 1은 배기가스의 유해성분을 정화 처리하기 위한 촉매 변환기이다.1 is a view showing an exhaust gas recirculation purification treatment apparatus according to the present invention, the numeral 1 in the figure is a catalytic converter for purifying the harmful components of the exhaust gas.
촉매변환기(1)로부터 배출되는 배기가스가 빠져나가는 통로인 후방 배기파이프(2)에는 배기가스 취출공(3)이 다수개 형성되고 그 취출공(3)이 주변부를 배기가스 취출부(4)가 감싸고 있다.A plurality of exhaust gas ejection holes 3 are formed in the rear exhaust pipe 2, which is a passage through which the exhaust gas discharged from the catalytic converter 1 exits, and the ejection holes 3 are formed at the periphery of the exhaust gas ejection unit 4. Is wrapping.
그리고 상기 촉매변환기(1)로 배기가스를 유입시키는 전방 배기파이프(5)에는 복수개의 배기가스 흡입공(6)이 형성되고 그 흡입공(6) 주변을 배기가스 재 흡입부(7)가 감싸고 있다.In addition, a plurality of exhaust gas suction holes 6 are formed in the front exhaust pipe 5 through which the exhaust gas is introduced into the catalytic converter 1, and the exhaust gas re-intake unit 7 surrounds the suction holes 6. have.
또한 상기 배기가스 취출부(4)와 배기가스 재 흡입부(7)는 배기가스 환류 공급관로(8)로 연결되어 있다.In addition, the exhaust gas extracting portion 4 and the exhaust gas re-suction portion 7 is connected to the exhaust gas reflux supply pipe (8).
이와 같은 본 고안은 촉매변환기(1)를 통하여 1차 정화 처리된 배기가스가 후방 배기파이프(2)를 통해 배출되는 과정에 배기가스 취출공(3)을 통해 배기가스 취출부(4)로 배기가스의 일부가 유입된 후 배기가스 환류 공급관로(8)를 통하여 배기가스 재 흡입부(7)로 이동되고 배기가스 흡입공(6)을 통하여 전방 배기파이프(5)로 유입된 후 다시 촉매변환기(1)를 통과하면서 2차로 정화 처리되어지게 된다.The present invention as described above is exhausted through the exhaust gas vent hole 3 to the exhaust gas outlet part 4 in the process of exhaust gas which has been firstly purified through the catalytic converter 1 through the rear exhaust pipe 2. After a part of the gas flows in, it is moved to the exhaust gas retake unit 7 through the exhaust gas reflux supply line 8 and flows into the front exhaust pipe 5 through the exhaust gas suction hole 6, and then the catalytic converter again. As it passes through (1), it becomes secondary purification.
여기서 배기가스 환류 공급관로(8)는 역류방지를 위해 도 2에서와 같이 흐름방향을 향하는 돌기(9)를 형성하는 것이 바람직하다.In this case, the exhaust gas reflux supply line 8 is preferably formed with a protrusion 9 facing the flow direction as shown in FIG. 2 to prevent backflow.
이상과 같은 본 고안에 의하면 엔진으로 배출되는 배기가스를 촉매변환기 전후에서 가스압력을 이용하여 재순환시켜 재정화처리하게 되므로써 정화 효율을 높여 환경 공해를 억제하게 되는 효과가 있다.According to the present invention as described above, the exhaust gas discharged to the engine is recycled and reprocessed by using gas pressure before and after the catalytic converter, thereby increasing the purification efficiency and suppressing environmental pollution.
