Description

회전날개 촉매 정화기{The Rotation Wings Catalyst Convertor}Rotating Wings Catalyst Convertor

내연기관의 실린더 안에서 혼합기가 압축후 폭발되고 나서, 이 연소된 가스를 외부로 배출하는 장치가 배기장치이다. 배기장치는 엔진구조의 마지막에 있으며 분진과 유해가스를 걸러주며 폭발소음과 엔진효율 등에 큰 영향을 미치는 매우 중요한 장치이다. 종래의 배기 시스템은 도 1에 도시된 바와 같이 배기가스를 모우는 배기매니폴드(1,Exhaust Manifold)와, 배기가스의 압력을 낮추어주는 송풍기 (2,bellows)와, 배기가스의 유해물질을 걸러주는 촉매정화기(3,Catalyst Convertor )와, 단면적을 확대함으로 인해 고온고압의 배기가스를 저온저압으로 낮추어 주는 소음기(4,Muffler)와, 배기가스가 대기중으로 방출되는 배기배출관 (5,Tail Pipe)으로 되어있다.In the cylinder of the internal combustion engine, after the mixer is compressed and exploded, the exhaust device is an apparatus for discharging the combusted gas to the outside. The exhaust system is at the end of the engine structure and it is a very important device that filters out dust and harmful gases and has a great influence on explosion noise and engine efficiency. Conventional exhaust systems filter exhaust manifolds (1, Exhaust Manifold), which collect exhaust gases, blowers (2, bellows) that lower the pressure of exhaust gases, and filter harmful substances as shown in FIG. The main unit is a catalytic converter (3, Catalyst Convertor), a silencer (4, Muffler) that lowers the high-temperature and high-pressure exhaust gas to a low-temperature low pressure by expanding the cross-sectional area, and an exhaust pipe (5, Tail Pipe) where the exhaust gas is released into the atmosphere. It is.

이중 상기 촉매정화기는 실린더내 혼합기의 불완전연소로 인해 생긴 유해성분인 일산화탄소(CO), 탄화수소(HC), 질소산화물(NOx) 등을 화학적으로 변화시키는 장치로서, 본 발명은 상기 촉매정화기를 날개가 회전함으로서 배기가스의 촉매통과를 원활하게 하여 배기가스의 유해물질을 효율적으로 걸러주는 새로운 개념의 촉매정화기이다.The catalytic purifier is a device for chemically changing carbon monoxide (CO), hydrocarbon (HC), nitrogen oxides (NOx), etc., which are harmful components caused by incomplete combustion of an in-cylinder mixer. It is a new concept of catalytic purifier that efficiently filters harmful substances in exhaust gas by smoothly passing catalyst through exhaust gas.

종래의 촉매정화기는 도 2에 도시한 바와같이, 배기가스가 일정한 방향으로 촉매를 통과하여 배기관으로 나가는 것으로서, 상기 촉매정화기 내부에는 촉매(삼원촉매 등)가 밀집되어 있음으로 인해 배기저항이 심하게 발생하고, 이로인해 엔진의 출력이 감소되는 문제점이 있으며, 배기저항을 감소시키기 위해 촉매를 얇게 만들면 배기가스 중의 유해성분을 제거하는 효과가 낮아졌다. 본 발명은 날개의 회전으로인해 배기가스를 촉매부에 통과시킴으로서 이런 문제점을 동시에 해결하여 엔진출력의 효율을 높이고,배기가스의 입자가 촉매부와 접촉하는 횟수(유효충돌횟수) 를 높여 배기가스의 유해성분을 충분히 제거할 수 있는 배기가스 정화장치를 만들기 위해서이다.As shown in FIG. 2, the conventional catalyst purifier exhaust gas passes through the catalyst in a predetermined direction and exits to the exhaust pipe, and exhaust resistance is severely generated because the catalyst (three-way catalyst, etc.) is concentrated inside the catalyst purifier. And, because of this there is a problem that the output of the engine is reduced, making the catalyst thin in order to reduce the exhaust resistance has a low effect of removing harmful components in the exhaust gas. The present invention solves this problem simultaneously by passing the exhaust gas through the catalyst part due to the rotation of the blade, thereby improving the efficiency of engine output, and increasing the number of times (effective collision) the particles of the exhaust gas are in contact with the catalyst part. This is to make an exhaust gas purification device that can remove the harmful components sufficiently.

첨부된 도면에 의해 상세히 설명하면 다음과 같다.When described in detail with the accompanying drawings as follows.

도 4는 본 발명에 따른 배기가스 구성도로서, 배기가스가 들어오는 배기가스 흡입관(10)과, 상기 배기가스 흡입관 외부에 형성되어져 있는 베어링(30)과, 상기 베어링을 둘러싸고 있는 회전날개 구동부(20)와, 상기 회전날개구동부를 회전시켜주는 벨트(40)와, 상기 회전날개 구동부 아랫부분에 형성되어져 있는 회전날개부 (60)와 상기 회전날개부를 둘러싸고 있는 촉매부와 상기 촉매부를 통과한 배기가스가 흐르는 배기가스통로(50)와, 상기 배기가스 통로를 거친 배기가스가 모여서 나가는 배기가스 배출관(5)으로 구성되어 있다.4 is an exhaust gas configuration diagram according to the present invention, the exhaust gas suction pipe 10 through which the exhaust gas enters, a bearing 30 formed outside the exhaust gas suction pipe, and a rotary wing drive unit 20 surrounding the bearing. ), A belt 40 for rotating the rotary wing drive unit, a rotary wing unit 60 formed below the rotary wing drive unit, a catalyst unit surrounding the rotary wing unit, and exhaust gas passing through the catalyst unit. And an exhaust gas discharge pipe 5 through which the exhaust gas passing through the exhaust gas passage collects and exits.

차량의 내연기관이 가동되기 시작하면 크랭크축을 회전시키게 되고, 상기 크랭크축에 벨트로 연결된 회전날개 구동부(20)가 회전을 하게된다. 상기 회전날개구동부(20)에서 회전을 함으로서 회전날개(60)를 회전시키고, 상기 회전날개(60)가 유해물질을 포함하고 있는 배기가스를 촉매부(7)로 강제로 밀어낸다. 회전날개(60)가 회전을 함으로서 배기가스가 촉매를 통과하는 힘을 높여주어서 종래의 배기장치가 가지고 있던 문제점인 배기저항을 감소시킬 수 있다. 배기저항을 감소시킴으로서 내연기관의 효율을 높일수 있고 또한 배기가스와 접촉하는 촉매가 회전날개(60)를 둘러싸고 있는 방식으로 구성되어져 있어서 그 접촉면적이 넓어져 배기가스의 유해성분을 넓어진 면적만큼 효율적으로 제거하게 된다. 상기 촉매부(7)는 배기가스 내 유해성분인 일산화탄소(CO), 탄화수소 (HC), 질소산화물(NOx) 등을 화학반응을 통해 이산화탄소(CO2)나 물(H2O) 등 무해한 물질로 바꾸어 준다.When the internal combustion engine of the vehicle starts to operate, the crankshaft is rotated, and the rotary wing drive unit 20 connected to the crankshaft by a belt rotates. The rotary blade 60 rotates by rotating in the rotary blade driving unit 20, and the rotary blade 60 forcibly pushes exhaust gas containing harmful substances into the catalyst unit 7. By rotating the rotary blade 60 it is possible to reduce the exhaust resistance which is a problem with the conventional exhaust apparatus by increasing the force of the exhaust gas passing through the catalyst. By reducing the exhaust resistance, the efficiency of the internal combustion engine can be increased, and the catalyst in contact with the exhaust gas surrounds the rotor blade 60 so that the contact area is widened, so that the harmful components of the exhaust gas can be efficiently as large as the enlarged area. Will be removed. The catalyst unit 7 is a harmless substance such as carbon dioxide (CO 2 ) or water (H 2 O) through a chemical reaction of carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx) and the like as harmful components in the exhaust gas. Change it.

배기가스가 상기 촉매부(7)를 통해 걸러지고 나면 배기가스 통로(50)로 나오고 상기 배기가스 배출관(5)을 통해 소음기(Muffler) 쪽으로 나오게 된다.After the exhaust gas is filtered through the catalyst unit 7, the exhaust gas is discharged to the exhaust gas passage 50 and the exhaust gas is discharged toward the muffler through the exhaust gas discharge pipe 5.

도 6은 본 발명에 따른 차량의 장치 구성도로서, 크랭크축의 동력을 변속기에 전달하는 플라이휠(100)과 상기 크랭크축의 외단에 설치되는 크랭크 풀리(90)와 상기 크랭크 풀리(90)와 플라이휠(100) 사이의 일부분에 축(110)을 설치하고 상기 축(110)의 일부분에 연결된 벨트(40)에 의해 회전날개 구동부(20)가 회전되는 회전날개 촉매정화기(80)를 개략적으로 도시하였다. 상기 크랭크 풀리(90)가 회전을 함으로서 회전날개 촉매정화기(80)에 형성되어져 있는 벨트(4)도 같이 회전하게되고 이로인해 상기 회전날개 촉매정화기(80) 내부에 있는 회전날개(60)와 촉매부(7)가 같이 회전을 하면서 배기가스의 유해성분을 걸러주게된다. 따라서 엔진의 회전수6 is a device configuration diagram of a vehicle according to the present invention, a crank pulley 90 and a crank pulley 90 and a flywheel 100 installed at an outer end of the crankshaft to transmit a power of a crankshaft to a transmission. The rotor blade catalyst purifier 80 is schematically illustrated in which a shaft 110 is installed at a portion between the shafts 110 and the rotor blade drive unit 20 is rotated by a belt 40 connected to a portion of the shaft 110. As the crank pulley 90 rotates, the belt 4 formed in the rotary wing catalyst purifier 80 also rotates, thereby rotating the blade 60 and the catalyst inside the rotary wing catalyst purifier 80. Part 7 rotates together to filter out harmful components of the exhaust gas. Thus the engine speed

(rpm)와 함께 회전날개 촉매정화기(80) 내부의 회전도 같이 변하므로 효율적으로 배기가스를 정화할 수 있게 된다.(rpm) and the rotation inside the rotary wing catalyst purifier 80 also changes so that it is possible to efficiently purify the exhaust gas.

이상에서 본 바와 같이, 본 발명에 의한 배기가스 정화장치는 배기가스를 회전날개에 의해 촉매부로 강제로 보내어주므로, 배기저항을 약화시켜 엔진의 출력효율을 높일수 있으며, 배기가스가 통과하는 촉매부의 면적이 넓어지고 배기가스의 입자가 촉매와 접촉하는 횟수(유효충돌횟수)를 높여 배기가스의 유해성분을 충분히 제거할 수 있다.As described above, the exhaust gas purifying apparatus according to the present invention forcibly sends the exhaust gas to the catalyst part by the rotary blades, thereby reducing the exhaust resistance and increasing the output efficiency of the engine, and the area of the catalyst part through which the exhaust gas passes. As a result, the number of times (effective collisions) that the particles of the exhaust gas come into contact with the catalyst can be increased to sufficiently remove the harmful components of the exhaust gas.
