일반적으로 디젤자동차용 배기가스정화장치는 디젤엔진이 배출하는 배기가스내에 함유되어 있는 유해 성분을 연소시켜 제거한 후 배출시키도록 한 장치로서 도 1에서와 같이,In general, an exhaust gas purifying apparatus for a diesel vehicle is a device for discharging and removing harmful components contained in exhaust gas emitted by a diesel engine, and then discharged.

엔진(10)으로부터 발생되는 배기가스를 각각의 실린더에 연결된 배기 매니폴더(12)를 통하여 배출하며,The exhaust gas generated from the engine 10 is discharged through the exhaust manifold 12 connected to each cylinder,

배출된 배기가스는 배기관(11)을 통해 제어밸브(13,14)를 거치면서 각각 머플러(15)와 정화장치(16)로 분리 배출된다.The discharged exhaust gas is separated and discharged through the control valves 13 and 14 through the exhaust pipe 11 to the muffler 15 and the purifier 16, respectively.

상기와 같이 연소가스를 배출하는 디젤엔진(10)은,Diesel engine 10 for discharging the combustion gas as described above,

스로틀센서와 회전수센서 및 압력을 지시하는 바로메터 등에서 측정된 신호값을 ECU(17)로 보내고, 여기에서 최적의 연소상태로 제어하기 위하여 각각의 센서로부터 입력신호를 기본값으로 하여 솔레노이드를 제어한다.The throttle sensor, the speed sensor, and the barometer indicating the pressure are sent to the ECU 17, and the solenoid is controlled based on the input signal from each sensor in order to control the optimum combustion state. .

이와 같이 전,후방에 장착된 각 엘보우(25)는,Thus, each elbow 25 mounted on the front and rear,

필터(23,24) 재생시, 배기가스의 유입량을 제어하여 필터재생시 요구되는 적정 온도 조절을 위한 컨트롤밸브(26)를 전방엘보우(25')에 장착하여 배기관(31)과 체결하고,When the filters 23 and 24 are regenerated, a control valve 26 is mounted on the front elbow 25 'to control the flow rate of the exhaust gas so as to adjust the temperature required for regenerating the filter.

To form a connection with.

상기와 같이 구성된 본 발명의 작용 상태를 종래 기술의 문제점과 비교하여 설명하면 다음과 같다.Referring to the operational state of the present invention configured as described above compared with the problems of the prior art as follows.

본 발명인 배기가스정화장치(2)는,Exhaust gas purification apparatus 2 of the present invention,

먼저, 통상 운행시 전방필터(23)로 유입되는 배기가스의 원활한 이송을 위해 전방엘보우(25')와 배기관(31) 상간에 개재된 컨트롤밸브(26)를 일정량 개방하고,First, the control valve 26 interposed between the front elbow 25 'and the exhaust pipe 31 is opened for a certain amount to smoothly transfer the exhaust gas introduced into the front filter 23 during normal operation,

전,후방필터(23,24) 상간의 이격 공간(L2)에 배기관(31)과 후방엘보우(25")를 통하여 개재되어 배기가스의 이송을 유도하는 on/off밸브(27)는 전방필터(23)를 통한 많은 량의 분진 포집이 이루어지도록 그 개방 각도를 조절한다.An on / off valve 27 interposed between the front and rear filters 23 and 24 via an exhaust pipe 31 and a rear elbow 25 "in a space L2 between the front and rear filters 23 and 24 is a front filter ( 23) Adjust the opening angle so that a large amount of dust is collected through.

상기와 같이 컨트롤밸브(26)를 비롯한 on/off 밸브(27)를 조절하여 원활한 배기가스의 정화와 배출이 이루어지는 상태에서 운행을 하며,By operating the on / off valve 27, including the control valve 26 as described above to operate in a state where the smooth exhaust gas purification and discharge,

이러한 운행 중 전, 후방필터(23,24)에 일정량의 분진이 포집될 경우 정화 성능 향상을 위해 필터재생 공정을 수행한다.If a certain amount of dust is collected in the front and rear filters 23 and 24 during this operation, the filter regeneration process is performed to improve the purification performance.

상기와 같이 필터재생 공정을 수행할 경우,When performing the filter regeneration process as described above,

우선적으로 전방필터(23)를 버너(21)의 열원을 통하여 재생한 후, 전방필터의 산화열을 이용하여 후방필터(24)의 재생 공정을 수행한다.First, the front filter 23 is regenerated through the heat source of the burner 21, and then the regeneration process of the rear filter 24 is performed using the heat of oxidation of the front filter.

이를 위해 초기 전방필터(23)의 재생 온도 상승을 위해 컨트롤밸브(26)는 전개(全開)하고, on/off 밸브(27)는 폐쇄하여 최대한의 배기가스가 전방필터(23)로 유입되도록 한 후,To this end, the control valve 26 is fully opened and the on / off valve 27 is closed to increase the regeneration temperature of the initial front filter 23 so that the maximum exhaust gas flows into the front filter 23. after,

이어 버너(21)를 착화시켜 그 열원을 통하여 전방필터(23)에 포집된 분진을소각하여 필터재생이 이루어지도록 한다.Then, the burner 21 is ignited to burn the dust collected in the front filter 23 through the heat source so that the filter is regenerated.

이와 같이 전방필터(23)가 재생되는 동안 컨트롤밸브(26)는 다시 적정 각도로 폐쇄하고, on/off밸브(27)는 개방 각도를 증가시켜 전방필터(23)의 재생시 배출되는 배기가스가 후방필터(24)를 통하여 여과되면서 배출되도록 하여 원활한 배기가스의 배출이 이루어지도록 한다.As such, while the front filter 23 is regenerated, the control valve 26 is closed again at an appropriate angle, and the on / off valve 27 increases the opening angle so that the exhaust gas discharged during the regeneration of the front filter 23 is discharged. It is discharged while being filtered through the rear filter 24 to facilitate the discharge of the exhaust gas.

상기와 같이 버너(21)를 통해 전방필터(23)의 재생이 완료됨과 동시에 그 폐열을 이용하여 후방필터(24)에 포집된 분진을 소각하여 재생함으로서 필터재생시간을 현격히 단축시킬 수 있다.As described above, the regeneration of the front filter 23 through the burner 21 is completed, and at the same time, by regenerating and regenerating the dust collected in the rear filter 24 using the waste heat, the filter regeneration time can be significantly shortened.

상기 후방필터(24) 재생시에는 컨트롤밸브(26)와 on/off밸브(27)의 개,폐 각도를 상반되게 설정하여 각 필터의 재생시에도 배출되는 배기가스의 여과 작용은 항상 유지될 수 있도록 한다.When the rear filter 24 is regenerated, the opening and closing angles of the control valve 26 and the on / off valve 27 are set opposite to each other so that the filtration action of the exhaust gas discharged even during regeneration of each filter is always maintained. .

이상에서와 같이 각 분진을 포집한 각 필터재생 작업중에도 배출되는 배기가스의 여과 작용은 이루어지는데,As described above, the exhaust gas is filtered even during each filter regeneration process in which dust is collected.

이는 종래 배기가스정화장치가 필터의 재생시 배출되는 배기가스를 별도구비된 머플러를 통하여 여과 작용 없이 배출함으로서 유발되는 환경오염등의 문제점을 해결할 수 있다.This can solve the problems such as environmental pollution caused by the conventional exhaust gas purification device to discharge the exhaust gas discharged during the regeneration of the filter through a separately equipped muffler without filtration action.

더불어 본 발명의 배기가스정화장치(2)는 필터재생과 배기가스 정화가 동시에 가능하여, 별도 구비되는 머플러를 삭제할 수 있어 원가 절감은 물론 차체중량을 감소시켜 연비 향상을 도모할 수 있다.In addition, the exhaust gas purifying apparatus 2 of the present invention is capable of simultaneously regenerating the filter and purifying the exhaust gas, so that a separate muffler can be removed, thereby reducing fuel costs and improving fuel efficiency by reducing the body weight.

이상과 같은 본 발명인 디젤자동차용 배기가스정화장치는 필터재생과 아울러 배기가스의 여과 작용이 동시에 가능하여 여과성능 향상에 따른 배기가스 오염도를 절감시켜 친환경적인 제품의 생산이 용이하며,Exhaust gas purifying apparatus for diesel vehicles according to the present invention as described above is capable of simultaneously regenerating the filter and filtering the exhaust gas, thereby reducing the pollution degree of the exhaust gas due to the improvement of the filtration performance, and easily producing environmentally friendly products.

별도의 머플러의 삭제가 가능하여 생산원가 절감 및 차제중량 감소에 따른 연료소비량 개선 등의 장점을 가지는 유용한 발명이다.It is a useful invention having the advantages of reducing the production cost and improving the fuel consumption according to the reduced vehicle weight by eliminating the separate muffler.
