도 3에 도시하는 것과 같이 흡기매니폴드(18)를 통해 엔진(1)으로 유입된 공기를 이용하여 실런더내로 분사된 연료를 연소시켜 동력을 얻은 후 연소된 배기가스는 배기매니폴드(2)를 통해 외부로 배출하게 되며, 고온 고압이며 다량의 인체 유해 가스를 함유하고 있는 배기가스에 의한 환경 오염을 방지하기 위해 촉매 정화기(4)와 소음 감쇠를 위한 머플러(5)를 통과시킨 후 대기로 방출하고 있다.As shown in FIG. 3, after the fuel injected into the cylinder is combusted by using the air introduced into the engine 1 through the intake manifold 18, the exhaust gas combusted is exhaust manifold 2. It is discharged to the outside through the catalyst purifier (4) and the muffler (5) for noise reduction in order to prevent the environmental pollution by the exhaust gas containing a high temperature and high pressure and a large amount of human harmful gas to the atmosphere Emitting.
엔진(1)은 통상 고강도이며 경량인 알루미늄 합금을 쓰고 있으나 흡,배기 매니폴드(8)(2)는 고가의 알루미늄 합금 대신 주로 저가의 주철로 주조하여 제작한 것을 사용하고 있다.The engine 1 is usually made of a high strength and lightweight aluminum alloy, but the intake and exhaust manifolds 8 and 2 are manufactured by casting mainly of inexpensive cast iron instead of the expensive aluminum alloy.

The inner surface of is peeled off and falls off.
이 떨어진 금속분(자성에 반응하는 Fe 성분을 말함)은 배기가스와 함께 배출되어지게 되는데 도중에 유해성분을 제거하기 위해 설치된 촉매정화기(4)의 벌집 모양의 촉매를 통과하면서 촉매를 손상시키게 되며, 쇳가루에 의해 촉매가 막히게 되면 배압을 상승시켜 엔진 성능을 저하시기게 되는 문제점이 있다.The separated metal powder (referring to the Fe component reacting to the magnetic) is discharged together with the exhaust gas, and the catalyst is damaged while passing through the honeycomb catalyst of the catalytic purifier 4 installed to remove harmful components. If the catalyst is blocked by the increase in the back pressure there is a problem that lowers the engine performance.
이에 본 발명은 상기한 문제점을 감안하여 제안한 것으로서 그의 목적으로 하는 것은 배기가스 속에 포함된 금속 분말이 촉매 정화기로 유입되기 전에 이를 분리시켜 제거하므로써 촉매 정화기의 손상을 방지하는 배기가스중의 금속분 제거장치를 제공하는 데 있다.Accordingly, the present invention has been proposed in view of the above problems, and its object is to remove metal powder contained in exhaust gas before it is introduced into the catalyst purifier to remove the metal powder in the exhaust gas, thereby preventing damage to the catalytic purifier.

도 1은 본 발명에 의한 배기가스 중의 금속분 제거장치가 설치된 배기계를 나타내는 도면이고, 도 2는 본 발명의 배기가스 중의 금속분 제거장치를 나타내는 상세단면도로서 도면중 부호 1 내지 5는 각각 엔진의 실린더 헤드, 배기매니폴드, 배기관, 촉매정화기 및 머플러이다.BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a view showing an exhaust system provided with an apparatus for removing metal powder in exhaust gas according to the present invention, and Fig. 2 is a detailed cross-sectional view showing a device for removing metal powder in exhaust gas according to the present invention. Exhaust manifolds, exhaust pipes, catalytic purifiers and mufflers.
상기 촉매정화기(4)의 전방 위치인 배기관(3)의 도중에는 본 발명에 의한 금속분 제거장치(6)가 접속되어 있다.The metal powder removing apparatus 6 according to the present invention is connected in the middle of the exhaust pipe 3 which is the front position of the catalyst purifier 4.
금속분 제거장치(6)는 일측 유입구(7)를 통해 유입된 배기가스가 타측 유출구(8)로 나갈때 통과하게 되는 유로(9)가 형성되어 있는 접속본체(10)와, 그 접속본체(10)에 착탈가능하게 나사(11)로 체결되는 금속분 포집함(12)과, 접속본체(10)내의 유로(9)상에 설치되어 유동하는 배기가스 중의 금속분을 흡착하는 전자석(13), 그리고 전자석(13)에 의하여 상기 유로(9)와 금속분 포집함(12)을 연통시키거나 또는 연통상태를 차단하는 밸브(14)와, 상기 전자석(13)이 여자되어 밸브(14)를 흡착시 압축되어지므로써 전자석(13)의 여자 상태가 해제되었을 때 밸브(14)를 하강시키도록 탄발하는 리턴스프링(15)을 포함하여 구성되어 있다.The metal powder removing device 6 includes a connection main body 10 having a flow path 9 through which exhaust gas introduced through one inlet 7 exits the other outlet 8, and the connection main body 10. A metal powder collecting box 12 fastened to and detachably attached to the screw 11, an electromagnet 13 adsorbing metal powder in exhaust gas flowing on the flow path 9 in the connection body 10, and an electromagnet ( 13, the valve 14 for communicating or blocking the communication state of the flow path 9 and the metal powder collecting box 12, and the electromagnet 13 is excited to be compressed when the valve 14 is adsorbed It comprises a return spring 15 which emits a shot so as to lower the valve 14 when the excited state of the electromagnet 13 is released.
전자석(13)은 시동키 스위치(16)에 연동하여 여자 및 여자 상태가 해제되며, 밸브(14)는 전자석(13)에 흡착되는 솔레노이드 밸브로 구성된다.The electromagnet 13 is interlocked with the ignition key switch 16 to release the excited and the excited state, the valve 14 is composed of a solenoid valve that is adsorbed by the electromagnet 13.
이와같은 본 발명의 구성에 의하면 시동키스위치(16)를 온하면 엔진이 시동되어 배기가스가 배기매니폴드(2)를 통하여 배출됨과 동시에 전자석(13)이 여자되어지게 된다.According to the configuration of the present invention as described above, when the start key switch 16 is turned on, the engine is started to exhaust the exhaust gas through the exhaust manifold 2 and the electromagnet 13 is excited.
전자석(13)이 여자되면 밸브(14)가 흡착되어 상승하여 밸브시트(17)에 밀착하므로써 유로(9)와 금속분 포집함(12)의 연통상태가 차단된다(도 2의 실선 도시 상태).When the electromagnet 13 is excited, the valve 14 is adsorbed and lifted up to be in close contact with the valve seat 17 so that the communication state between the flow path 9 and the metal dust collector 12 is interrupted (solid line shown in FIG. 2).
이때 배기관(3)을 통과하여 배출되는 배기가스는 도중에 접속된 금속분 제거장치(6)의 유로(9)를 지나게 되며, 그 유로(9)내에 설치되어 있는 전자석(13)에 배기가스중에 포함되어 있는 미세한 쇳가루가 흡착 분리되어지게 되는 것이다.At this time, the exhaust gas discharged through the exhaust pipe (3) passes through the flow path (9) of the metal powder removing device (6) connected in the middle, and is contained in the exhaust gas in the electromagnet (13) installed in the flow path (9). Fine lump powder will be adsorbed and separated.
이에따라 그 후방의 촉매정화기(4)에 유입되는 배기가스속에는 촉매정화기(4)를 손상시킬 주철 마모 분말이 포함되어 있지 않아 촉매정화기(4)의 손상 및 배기계를 막히게 하여 일어나는 배압 증가를 가져오지 않게 된다.Accordingly, the exhaust gas flowing into the rear of the catalytic purifier 4 does not contain cast iron abrasion powder which will damage the catalytic purifier 4 so that the catalyst purifier 4 is not damaged and the exhaust system is blocked to increase the back pressure. do.
한편 엔진의 시동을 끄면 전자석(13)의 여자 상태(자성)가 소거되면서 전자석(13) 표면에 흡착되어 있던 쉿가루는 중력에 의해 하방으로 낙하하게 되는데 이때 전자석(13)의 자성이 소거됨과 동시에 중력 및 리턴스프링(15)에 의해 밸브(14)가 하강하여 밸브시트(17)로부터 이격되기 때문에(도 2의 일점쇄선 도시 참조) 낙하하는 쇳가루는 금속분 포집함(12)으로 낙하, 회수되어지게 되며, 금속분 포집함(12)내에 수집된 금속분이 일정량에 도달하면 금속분 포집함(12)을 접속분체(10)로부터 분해하여 쇳가루를 털어낸 후 다시 체결 장착하여 재사용 하게 되는 것이다.On the other hand, when the engine is turned off, the excited state (magnetism) of the electromagnet 13 is canceled, and the shhh powder adsorbed on the surface of the electromagnet 13 drops downward due to gravity. Since the valve 14 is lowered and separated from the valve seat 17 by gravity and the return spring 15 (see the dashed-dotted line shown in FIG. 2), the falling powder is dropped and recovered by the metal powder collecting box 12. When the metal powder collected in the metal powder collecting box 12 reaches a predetermined amount, the metal powder collecting box 12 is decomposed from the connecting powder 10 to shake off the powder and reused by tightening again.
다시 엔진이 시동되면 전자석(13)은 자성을 갖게되어 배기가스 중의 쇳가루를 흡착하게 되고, 밸브(14)는 전자석(13)에 흡착되어 상승하여 밸브시트(17)에 밀착하게 되므로써 금속분 포집함(12)내의 쇳가루가 유로(9)측으로 역류하는 것이 방지된다.When the engine is started again, the electromagnet 13 becomes magnetic and absorbs fine powder in the exhaust gas, and the valve 14 is absorbed by the electromagnet 13 and ascends and adheres to the valve seat 17 to collect metal powder. The dust in 12) is prevented from flowing back to the flow path 9 side.
이상과 같은 본 발명에 의하면 주철재의 배기매니폴드가 고온의 배기가스에 의해 산화되어 쇳가루가 발생하여 배기가스 속에 포함되어 배출되더라도 촉매 정화기 앞에 설치된 전자석에 의해 흡착되기 때문에 촉매 정화기의 손상 및 배기계의 막힘 현상에 의한 배압 증가를 방지하게되며, 전자석이 엔진의 시동과 연계되고 또 전자석에 의해 개폐되는 밸브 및 접속본체와 착탈가능하게 장착된 금속분 포집함의 구성에 의해 흡착된 쇳가루의 안전한 회수 및 사후처리가 가능한 효과가 있다.According to the present invention as described above, even if the exhaust manifold of the cast iron is oxidized by the high-temperature exhaust gas and the flakes are generated and included in the exhaust gas, the exhaust manifold is adsorbed by the electromagnet installed in front of the catalytic purifier, thereby causing damage to the catalytic purifier and the exhaust system. Prevents back pressure increase due to clogging phenomenon and safe recovery and post-treatment of crushed powder adsorbed by the configuration of a metal dust collector which is detachably mounted with a valve and a connection body in which an electromagnet is connected to the engine starting and opened and closed by an electromagnet Has the possible effect.
