Description

디젤 자동차의 매연 저감 여과장치Soot Reduction Filter of Diesel Vehicle

본 발명은 디젤자동차의 매연 저감 여과장치에 관한 것으로서, 보다 상세하게는 빈 내부 공간에 비중이 높고 크기가 작은 볼이 내장된 미세다공 볼 형태의 촉매제를 이웅하여 배기가스 및 입자상 물질의 연소 여과처리 효과가 매우 우수한, 디젤자동차의 매연 저감 여과장치에 관한 것이다.The present invention relates to an apparatus for reducing smoke in diesel vehicles, and more particularly, combustion filtration of exhaust gas and particulate matter by degrading catalysts in the form of microporous balls having high specific gravity and small sized balls in empty interior spaces. The present invention relates to a diesel particulate filter for reducing smoke.

산업이 발달됨에 따라 유류 및 화석연료의 연소, 제철, 제강, 시멘트 제조 및 폐기물 소각 공정 등에서 발생되는 각종 미세먼지 오염물질들은 대기오염의 주종을 이루면서 인간에게 상당한 피해를 끼치고 있다.As the industry develops, various fine dust pollutants generated from the combustion of oil and fossil fuels, steelmaking, steelmaking, cement manufacturing, and waste incineration processes are causing major air pollution, causing considerable damage to humans.

그런데 80년대 후반에 들어와 급격히 증가한 자동차는 전국토를 주차장화 하면서 많은 오염물질을 배출하여 이러한 대기오염 문제를 더욱 더 가중시키고 있는데, 자동차에서 배출되는 오염물질은 대기중의 질소산화물과 오존농도 및 미세한 부유먼지의 농도를 증가시킨다.However, the rapid increase of automobiles in the late 80's has caused a lot of pollutants by parking lot of the whole country, making the air pollution problem more and more.The pollutants emitted from automobiles are nitrogen oxides and ozone concentration and fine suspension in the air. Increase the concentration of dust

즉 대기오염의 주범이 산업현장이나 난방연료와 같은 고정 배출원에서 자동차와 같은 이동 배출원으로 바뀌어진 것이다.In other words, the main cause of air pollution has changed from fixed sources such as industrial sites or heating fuels to mobile sources such as automobiles.

70년대 이후 매년 100만대씩 급격하게 증가하는 자동차의 배출가스를 엄격하게 규제하였음에도 불구하고 자동차에 의한 도시 대기오염은 전체적으로 개선될 기미를 보이지 않고 있으며 부유먼지의 배출량은 계속적으로 증가하여 국민건강을 위협하고 있는 실정이다.Despite severe restrictions on automobile emissions, which have rapidly increased by one million vehicles every year since the 1970s, urban air pollution by automobiles has not shown any improvement, and emissions of suspended dust continue to increase, threatening national health. I'm doing it.

일반적으로 디젤엔진의 배기가스는 공연비가 크고, 일산화탄소(CO) 및 탄화수소(HC)의 배출이 적으며, 압축비가 크고 소음 및 진동이 심하며 질소산화물(NOX), 황산화물(SOX)의 생성이 많을 뿐 아니라 배출가스 중에 매연(Smoke)을 포함한 입자상 물질이 많은 특성이 있다.In general, the exhaust gas of diesel engines has a high air-fuel ratio, low emissions of carbon monoxide (CO) and hydrocarbons (HC), high compression ratio, high noise and vibration, and generation of nitrogen oxides (NO X ) and sulfur oxides (SO X ). In addition to this, there are many characteristics of particulate matter including smoke in the exhaust gas.

특히 상기 입자상물질은 스폰지 형태의 탄소 입자로 많은 독성 화학물질을 포함하고 있으며, 직경 0.1μm∼0.3μm의 매우 작은 크기의 입자가 분포를 이루므로 흡착성이 강하고, 작고 가벼워 공기중에 오랫동안 떠돌아 다닌다.In particular, the particulate matter is a sponge-like carbon particles containing a lot of toxic chemicals, because the particles of a very small size of 0.1μm to 0.3μm in diameter is distributed, the adsorption is strong, small and light, and float in the air for a long time.

이러한 디젤엔진에서 배출되는 유해성분을 감소시키기 위하여 필터를 사용하는 방법이 많이 활용되어 왔는데 그 중 가장 각광 받는 방법이 벽을 이용하는 하니컴과 세라믹 화이버를 이용한 필터 포집 방법이다.In order to reduce harmful components emitted from diesel engines, a method of using a filter has been widely used. Among them, the most popular method is a filter collection method using a honeycomb and a ceramic fiber using a wall.

상기 필터 포집 방법은 입자상 물질을 제거시키는 방식에 따라 버너, 전기히터, 연료 첨가제 등을 이용하는데 이 때 재생과정에서 내열성(열충격), 내구성 등의 문제로 인한 균열이 발생하여 필터가 쉽게 파손되는 문제점이 있었다.The filter collection method uses a burner, an electric heater, a fuel additive, etc. according to a method of removing particulate matter, in which a crack is generated due to problems such as heat resistance (heat shock) and durability in the regeneration process, and thus the filter is easily broken. There was this.

또한 입자상 물질이 미세다공 벽면에 의해 포집된 후 미세다공에 쉽게 부착되어 미세다공을 폐쇄시키게 되므로 통기성이 점차 저하될 뿐 아니라 입자상 물질의 축적과 이로 인한 막힘 현상에 의해 배압이 증가되어 필터의 사용주기가 짧아지며 재생과정에서 발생하는 발열로 인해 쉽게 필터가 파손되는 문제점이 있었다.In addition, since the particulate matter is collected by the microporous wall and easily attached to the micropore to close the micropores, not only the air permeability is gradually lowered but also the back pressure is increased due to the accumulation of particulate matter and the blockage caused by the filter. Was short and there was a problem that the filter is easily broken due to the heat generated during the regeneration process.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서 디젤자동차의 배기가스와 함께 배출되는 유해물질을 근본적으로 제거할 수 있는 디젤자동차의 매연 저감 여과장치를 제공하는 것을 목적으로 한다.The present invention has been made in order to solve the above problems, and an object of the present invention is to provide a smoke reduction filter device for diesel vehicles that can fundamentally remove harmful substances discharged together with the exhaust gas of diesel vehicles.

본 발명의 다른 목적은 배압 증가 현상이 일어나지 않는 촉매제를 사용하여 사용주기가 길고 경제적인 디젤자동차의 매연 저감 여과장치를 제공하는 것이다.It is another object of the present invention to provide a smoke reduction filter device of a diesel vehicle having a long service life and economical efficiency by using a catalyst that does not occur an increase in back pressure.

본 발명의 상기 목적들은 필터에 의한 여과방법이 아닌 빈 내부공간에 작은볼이 내장된 미세다공 형태의 볼(Ball)을 이용하는 매연 저감 여과장치를 제공함으로써 달성되는데, 상기 미세다공 볼은 단위 체적당 접촉면적 및 입자상 물질에 대한 담지량이 매우 커서 효과적으로 배기가스를 정화시킬 수 있으며, 패생과정에서도 내열성, 내구성 등이 우수하여 파손될 우려가 없다.The above object of the present invention is achieved by providing a smoke reduction filter device using a ball of a microporous form in which a small ball is embedded in an empty interior space, rather than a filtration method by a filter, wherein the microporous ball is per unit volume. The amount of contact on the contact area and the particulate matter is very large, so that the exhaust gas can be effectively purified, and there is no fear of damage due to its excellent heat resistance and durability even in the process of defeat.

특히, 본 발명은 미세다공 볼과 볼 사이 및 볼의 표면에 형성된 기공사이로 배기가스가 흐를 수 있어 배압의 증가없이 일정배압을 유지할 수 있게 되므로 반영구적인 사용이 가능하다.In particular, the present invention can be used semi-permanently because the pores formed between the microporous ball and the ball and the surface of the ball can be exhaust gas flow to maintain a constant back pressure without increasing the back pressure.

본 발명은 다수의 미세공이 형성된 차단판에 의해 챔버과 챔버로 분리 구획되는 케이싱과; 상기 케이싱의 전방에서 챔버 내부를 관통하여 챔버에 설치되며 챔버 통과부에 다수의 미세공이 형성된 인입가스 유도관과; 상기 케이싱 하방 경사부호퍼에 설치되는 전기히터와; 상기 챔버에서 챔버을 관통하여 케이싱 후방으로 설치되며, 챔버 통과부에 다수의 미세공이 형성된 배기가스 유도관을 포함하여 구성되는 디젤자동차의 매연저감 여과장치에 있어서, 상기 챔버와 챔버 내부에는, 표면에 직경 0.1mm∼10mm의 미세다공이 형성되고 빈 내부 공간에 비중이 높고 크기가 작은 볼이 내장된 미세다공 볼이 채워진 것을 특징으로 하는, 디젤자동차의 매연저감 여과장치에 관한 것이다.The present invention and the casing is divided into a chamber and the chamber by a blocking plate formed with a plurality of micropores; An inlet gas induction pipe installed in the chamber through the inside of the chamber at the front of the casing and having a plurality of micropores formed therein; An electric heater installed at the lower portion of the casing hopper; In the chamber, passing through the chamber is installed in the rear of the casing, and the exhaust gas filtration device of the diesel vehicle comprising an exhaust gas induction pipe formed with a plurality of fine holes in the chamber passage, the chamber and the inside of the chamber, the diameter on the surface It relates to a particulate filter of the diesel vehicle, characterized in that the fine pores of 0.1mm to 10mm is formed and the hollow inner space is filled with microporous balls having a high specific gravity and small balls.

상기와 같이 구성되는 본 발명 디젤자동차의 매연 저감 여과장치를 이용한 매연 저감 과정을 살펴보면 디젤자동차에서 배출되는 배기가스가 단위 체적당 접촉면적 및 입자상 물질에 대한 담지량이 매우 른 미세다공 형태의 볼을 통과하면서 정화된 후 배출되는 것이다.Referring to the smoke reduction process using the smoke reduction filter of the diesel vehicle of the present invention configured as described above, the exhaust gas discharged from the diesel vehicle passes through the microporous ball having a very different contact area and support amount for particulate matter per unit volume. It is purified and then discharged.

즉, 배기가스중에 포함된 입자상물질들이 상기 미세다공 볼 표면에 부착되어 서로 결합하게 되면서 비중이 높아지게 되고, 이와 같이 입자상 물질이 부착된 미세다공 볼은 자동차 운행시의 흔들림과 엔진에서 발생하는 맥동 흐름에 의해 움직이게 되므로 입자상물질들이 아래쪽 호퍼로 모이게 되고 이렇게 호퍼에 모여진 입자상 물질들이 전기히터로 연소처리되어 제거되는 것이다.That is, as the particulate matter contained in the exhaust gas is attached to the surface of the microporous ball and combined with each other, the specific gravity is increased. Since the particulate matter is collected in the lower hopper and the particulate matter collected in the hopper is burned and removed by an electric heater.

이하 본 발명의 바람직한 실시예를 첨부된 도면에 의거하여 구체적이고 상세하게 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention in detail and in detail as follows.

본 발명은 제1, 3, 4도에 도시된 바와 같이 통상의 형상으로 이루어진 케이싱(1)의 전방에서 챔버(12)와 챔버(11)의 내부를 통과하여 인입가스 유도관(2)이 설치되며, 배기가스 유도관(4)이 챔버(12)에서 챔버(11)로 통과하여 케이싱(1) 뒤쪽까지 빠져나와 구성된다.In the present invention, the incoming gas guide pipe (2) is installed through the interior of the chamber (12) and the chamber (11) in front of the casing (1) having a general shape as shown in FIG. The exhaust gas guide pipe 4 passes from the chamber 12 to the chamber 11 and exits to the rear of the casing 1.

상기 케이싱(1)에는 다수의 미세공(9)이 형성된 차단판(5)을 설치하여 챔버(11)에서 챔버(12)쪽으로 배기가스를 유도 분산시켜 구획하고, 금속이나 세라믹 재질의 내열성, 내마모성, 내구성이 우수한 미세다공 볼(7)을 챔버(11)와 챔버(12)에 채우고, 케이싱(1) 아래쪽 내부 경사부분 호퍼(8)에 전기히터(3)를 설치한다.The casing 1 is provided with a blocking plate 5 in which a plurality of micropores 9 are formed, thereby inducing and distributing the exhaust gas from the chamber 11 toward the chamber 12, and separating heat and abrasion resistance of the metal or ceramic material. The highly porous microporous ball 7 is filled in the chamber 11 and the chamber 12, and the electric heater 3 is installed in the inclined portion hopper 8 under the casing 1.

따라서, 디젤엔진에서 배출되는 배기가스는 인입가스 유도관(2)으로 인입되어 챔버(12)를 통과한 후 챔버(11)에서 챔버(11)의 인입가스유도관(2)에 형성되어 있는 직경 1∼20mm인 다수의 미세공(6)을 통해 방출된다.Therefore, the exhaust gas discharged from the diesel engine is introduced into the inlet gas induction pipe (2), passes through the chamber 12, and the diameter formed in the inlet gas induction pipe (2) of the chamber (11) in the chamber (11) It is emitted through a plurality of micropores 6 of 1 to 20 mm.

상기 배기가스는 챔버(11)에 채워진 촉매제 미세다공 볼(7)에 의해 대부분 정화되어 챔버(12)로 넘어가게 된다.The exhaust gas is mostly purified by the catalyst microporous ball 7 filled in the chamber 11 to be passed to the chamber 12.

상기 미세다공 볼(7)은 제2도에 도시된 바와 같이, 표면에 직경 0.1mm∼10mm의 미세다공(13)이 형성되고 빈 내부 공간에 비중이 높고 크기가 작은 볼(14)이 내장되어 구성 된다.As shown in FIG. 2, the microporous ball 7 has a micropore 13 having a diameter of 0.1 mm to 10 mm on its surface, and a ball 14 having a high specific gravity and a small size is embedded in an empty interior space. It is composed.

배기가스와 함께 배출된 입자상 물질은 챔버(11)내에 채워진 미세다공 볼(7)의 표면과 내부에 안착되어 지속적으로 배기되는 입자상 물질과 서로 결합하게 되어 입자 크기가 점차 커지게 된다.The particulate matter discharged together with the exhaust gas is seated on the surface and inside of the microporous ball 7 filled in the chamber 11 and is coupled to the particulate matter continuously exhausted, thereby gradually increasing the particle size.

이와 같이 미세다공 볼의 표면과 내부에 안착되어 커진 입자상 물질은 운행중인 자동차의 흔들림과 엔진에서 발생하는 맥동 흐름이 미세다공 볼(7)에 전달되어 미세다공 볼(7)이 움직이게 됨에 따라 아래쪽 호퍼(8)로 낙하되어 모이게 되며, 모여진 입자상 물질은 챔버(11) 아래쪽에 있는 전기히터(3)에 의해 연소되어 제거 된다.As such, the particulate matter that has been settled on the surface and inside of the microporous ball is transferred to the microporous ball 7 by the vibration of the vehicle and the pulsation flow generated from the engine, so that the microporous ball 7 moves to the lower hopper. Dropped and collected in (8), the collected particulate matter is burned and removed by the electric heater (3) below the chamber (11).

이 때, 챔버(11)에서 미처 처리되지 못한 일부 적은 양의 입자상 물질은 챔버(17)로 이동한 다음 챔버(12)에 채워진 미세다공 볼(7)에 의해 상기와 동일한 단계를 거쳐 연소되어 제거된다.At this time, some small amount of particulate matter which has not been treated in the chamber 11 is moved to the chamber 17 and then burned and removed by the same steps as described above by the microporous ball 7 filled in the chamber 12. do.

이와 같이 입자상 물질이 전기히터(3)에 의해 완전 연소되어 정화된 배기가 챔버(12)의 배기가스 유도관(4)에 형성되어 있는 직경 1∼20mm의 미세공(10) 들어가 배기가스유도관(4)을 통해 밖으로 방출된다.The exhaust gas in which the particulate matter is completely burned by the electric heater 3 and purged enters the fine pores 10 having a diameter of 1 to 20 mm formed in the exhaust gas induction pipe 4 of the chamber 12. (4) is released out through.

본 발명은 배기가스와 함께 배출되는 입자상 물질을 단위 체적당 접촉면적이 큰 미세다공 볼 형태의 촉매제를 이용하여 제거함으로써 배기가스 정화 효과가 매우 우수하다.The present invention is very excellent in the exhaust gas purification effect by removing the particulate matter discharged with the exhaust gas by using a catalyst in the form of a microporous ball having a large contact area per unit volume.

또한, 상기 미세다공 볼은 입자상 물질에 대한 담지량이 뚜척 크므로 입자상 물질들을 서로 결합시켜 비중을 높이고, 운전시의 흔들림과 엔진에서 발생하는 맥동 흐름을 이용하여 상기 미세다공 볼이 움직이도록 함으로써 미세다공 볼 표면에 붙은 입자상 물질을 케이싱 하방 경사부 호퍼로 모이게 하고 전기히터를 사용하여 모아진 입자상 물질을 지속적으로 연소시켜 입자상 물질을 제거할 수 있게 되므로 디젤자동차에서 배출되는 유해 물질을 근본적으로 차단할 수 있다.In addition, since the microporous ball has a large amount of support for particulate matter, the particulate matter is bonded to each other to increase specific gravity, and the microporous ball moves by using the pulsation flow generated from the engine and the shaking during operation. The particulate matter adhered to the ball surface is collected in the hopper down the casing, and the particulate matter is continuously burned by using an electric heater to remove particulate matter, thereby fundamentally blocking harmful substances emitted from diesel vehicles.

그리고, 본 발명은 배압의 증가없이 일정배압을 유지할 수 있어 반영구적인 사용이 가능하며, 장치의 구조가 간단하고 장착이 용이하여 기존 디자인의 변경없이도 장착이 가능할 뿐 아니라 현재 운행중인 차량에도 쉽게 부착하여 사용할 수 있으므로 매우 경제적이다.In addition, the present invention can maintain a constant back pressure without increasing the back pressure can be used semi-permanently, the structure of the device is simple and easy to install it can be installed without changing the existing design as well as easily attached to the vehicle currently in operation Very economical because it can be used.
