원심회전기를 이용한 차량용 매연저감장치Vehicle smoke reduction device using centrifugal rotor

본 발명은 차량의 엔진에서 배출되는 배출가스에 포함된 오염물질을 제거하여 정화된 가스를 배기하기위해 배출가스관내의 일부분에 설치되는 원심회전기를 이용한 차량용 매연저감장치에 관한 것이다.The present invention relates to a vehicle smoke reduction device using a centrifugal rotor installed in a part of the exhaust gas pipe to remove the pollutants contained in the exhaust gas discharged from the engine of the vehicle to exhaust the purified gas.

일반적으로 차량의 주행시 엔진에서 발생되는 배출가스에는 불완전연소에 의해 발생된 인체에 유해한 입자상물질을 포함하고 있다.In general, the exhaust gas generated from the engine while driving the vehicle contains particulate matter harmful to the human body caused by incomplete combustion.

상기 입자상물질을 제거하기위해 연소를 촉진시키는 첨가제를 연료와 함께 주입하여 배기가스의 온도만으로 상기 입자상물질을 제거하는 방법이 이용되었으나 상기 첨가제가 소모성이기 때문에 고비용이고, 또 다른 정화방법은 매연여과장치를 사용하는 방법이며, 이 장치의 구성은 도 1에 도시한 바와같이 주입구(12) 및 배출구(14)가 형성되어 있는 하우징(10)과, 상기 주입구(12)를 통해 주입된 배출가스(1)에 포함된 입자상물질을 여과하여 연소시키도록 상기 하우징(10)내에 길이방향으로 이격설치되고, 내부에는 벌집모양의 다수의 통로가 형성되어 있으며, 도시하지않은 전원공급장치에서 전원을 인가받아 발열하는 열선이 내설되어 있는 다수의 세라믹필터(20)와, 상기 세라믹필터(20)의 일단부에 상호 교대로 설치되어 봉합하는 차단막(30)으로 이루어져 있다.In order to remove the particulate matter, a method of removing the particulate matter by injecting an additive which promotes combustion together with fuel to remove the particulate matter is only expensive because the additive is consumable, and another purification method is a soot filtration device. As shown in FIG. 1, the apparatus includes a housing 10 in which an inlet 12 and an outlet 14 are formed, and the exhaust gas 1 injected through the inlet 12. Installed in the housing 10 in the longitudinal direction so as to filter and burn the particulate matter contained in the), there are formed a plurality of passages in the shape of a honeycomb, heat generated by receiving power from a power supply (not shown) A plurality of ceramic filters 20 in which hot wires are installed, and a blocking film 30 alternately installed at one end of the ceramic filter 20 and sealed. There adjuster.

이와같이 구성된 종래의 매연여과장치의 작용을 설명하면 다음과 같다.Referring to the operation of the conventional soot filtration device configured as described above are as follows.

먼저, 엔진의 배기포트로부터 배출된 배출가스가 주입구(12)에 주입되면, 배출가스는 유속에 의해 계속해서 전진하여 세라믹필터(20)를 통과하면서 배출가스에 포함된 입자상 물질이 이 세라믹필터(20)에 걸러지고, 이 입자상물질은 상기 세라믹필터(20)내에 설치된 열선으로부터 발생되는 열에 의해 연소되어 최종적으로는 배출구(14)를 통해 정화된 배기가스(3)가 배출된다.First, when the exhaust gas discharged from the exhaust port of the engine is injected into the injection port 12, the exhaust gas is continuously advanced by the flow rate and passes through the ceramic filter 20, the particulate matter contained in the exhaust gas is the ceramic filter ( 20, the particulate matter is burned by the heat generated from the heating wire installed in the ceramic filter 20, and finally, the exhaust gas 3 purified through the exhaust port 14 is discharged.

그런데, 이와같은 매연여과장치를 이용한 방법은 입자상물질이 세라믹필터(20)내의 통로에 과다하게 축적되면 일시적으로 배압이 걸려 엔진출력등에 문제를 일으킬 수 있으며, 입자상물질의 연소시 상기 세라믹필터가 열적파손될 위험이 있다는 문제점이 있었다.However, in the method using such a soot filtration device, if excessive particulate matter accumulates in the passage in the ceramic filter 20, the back pressure may be temporarily applied to cause an engine output problem. There was a problem that there is a risk of breakage.

또다른 문제점은 세라믹필터의 재생과정에서 별도의 부대시설이 필요하여 장치가 커지고 비용이 많이 든다는 것이다.Another problem is that additional equipment is required in the process of regenerating the ceramic filter, which makes the apparatus larger and more expensive.

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위해 이루어진 것으로서, 본 발명의 목적은 엔진의 출력에 문제를 일으키지않고, 열적파손의 위험이 없으며, 매연필터의 재생에 필요한 부대시설이 필요없는 원심회전기를 이용한 차량용 매연저감장치를 제공하는데 있다.Therefore, the present invention has been made to solve the above problems, the object of the present invention does not cause a problem in the output of the engine, there is no risk of thermal damage, a centrifugal rotor that does not need the auxiliary facilities required for the regeneration of the soot filter To provide a vehicle smoke reduction device using.

도 2는 본 발명의 일실시예에 의한 원심회전기를 이용한 차량용 매연저감장치의 구성을 도시한 부분적인 종단면도로서, 단열막(300)은 하우징(200)내주면에 설치되어 단열작용을 하고, 주입관(100)은 엔진의 배기포트에서 배출되는 배출가스를 후술되는 가열막(400)내부의 공간에 주입하도록 하우징(200)과 상기 단열막(300) 및 가열막(400)을 관통하여 설치되어 있고, 회전기(500)는 상기 주입관(100)을 통해 주입되는 배출가스의 유속에 의해 회전하여 후술되는 가열막(400)의 표면에 배출가스에 포함된 유해한 입자상물질을 흡착시키기위해 원심력을 제공하는 역할을 한다.Figure 2 is a partial longitudinal cross-sectional view showing the configuration of a vehicle smoke reduction device using a centrifugal rotor according to an embodiment of the present invention, the thermal insulation film 300 is installed on the inner peripheral surface of the housing 200 to insulate, injection Pipe 100 is installed through the housing 200 and the heat insulating film 300 and the heating film 400 to inject the exhaust gas discharged from the exhaust port of the engine into the space inside the heating film 400 to be described later The rotor 500 is rotated by the flow rate of the exhaust gas injected through the injection pipe 100 to provide centrifugal force to adsorb harmful particulate matter contained in the exhaust gas on the surface of the heating membrane 400 to be described later. It plays a role.

그리고, 가열막(400)은 상기 단열막(300)의 내주면에 설치되어 상기 회전기(500)의 원심력에 의해 유도된 배출가스에 포함된 유해물질을 흡착하여 연소시키도록 표면은 표면적이 넓도록 구불구불한 형태로 이루어지고, 재질은 섬유질 망사구조로 구성된 여과포로 이루어져 있으며, 내부에는 도시하지않은 전원장치에 의해 발열하는 열선이 형성되어 있다.In addition, the heating film 400 is installed on the inner circumferential surface of the heat insulating film 300 and the surface is bent so that the surface area is wide so as to adsorb and burn harmful substances contained in the exhaust gas induced by the centrifugal force of the rotor 500. It is made of a twisted shape, and the material is made of a filter cloth composed of a fibrous mesh structure, and a heating wire is formed therein by a power supply device (not shown).

또한, 배출관(600)은 상기 가열막(400)에 의해 제거된 정화가스를 외부로 방출하도록 상기 가열막(400)과 단열막(300) 및 하우징(200)을 관통하여 설치되어 있다.In addition, the discharge pipe 600 is installed to penetrate the heating membrane 400, the heat insulating membrane 300, and the housing 200 to discharge the purge gas removed by the heating membrane 400 to the outside.

상기와 같은 요소들로 구성된 본 발명의 일실시예에 의한 원심회전기를 이용한 차량용 매연저감장치에 대한 작용을 설명하기로 한다.It will be described the operation of the vehicle smoke reduction device using a centrifugal rotor according to an embodiment of the present invention composed of the above elements.

먼저, 엔진의 배기포트에서 배출된 오염된 배출가스가 주입관(100)을 통해 가열막(400)의 내부공간에 주입됨에 따라 배출가스의 유속에 의해 회전기(500)가 회전하게 되어 원심력이 발생함으로써 배출가스는 가열막(400)으로 유도되며, 이 가열막(400)의 표면에 배출가스에 포함된 유해한 입자상물질이 흡착된다.First, as the polluted exhaust gas discharged from the exhaust port of the engine is injected into the inner space of the heating membrane 400 through the injection pipe 100, the rotor 500 rotates due to the flow rate of the exhaust gas, thereby generating centrifugal force. As a result, the exhaust gas is guided to the heating membrane 400, and harmful particulate matter contained in the exhaust gas is adsorbed onto the surface of the heating membrane 400.

이때, 입자상물질은 상기 가열막(400)의 발열에 의해 연소되어 정화된 배기가스가 배출관(600)을 통해 외부로 배출된다.At this time, the particulate matter is burned by the heating of the heating film 400 and the purified exhaust gas is discharged to the outside through the discharge pipe 600.

상술한 바와 같이 본 발명에 의한 원심회전기를 이용한 차량용 매연저감장치는 필터를 사용하지 않으므로 필터내의 통기공에 입자상물질이 축적되지않아 배압에의한 연료소비율을 악화시키지 않아 엔진의 출력에 문제를 일으키지않고, 필터의 열적파손이 생기지 않으며, 필터의 여과재생에 필요한 부대시설이 필요없게되어 비용면에 있어서 경제적이라는 뛰어난 효과가 있다.As described above, since the vehicle smoke reduction device using the centrifugal rotor according to the present invention does not use a filter, particulate matter does not accumulate in the air vents in the filter, and thus does not deteriorate fuel consumption due to back pressure, thereby causing problems in engine output. In addition, the thermal damage of the filter does not occur, and there is no need for additional facilities necessary for the filtration and regeneration of the filter, which has an excellent cost-effective effect.
