본 발명은 자동차 촉매컨버터의 담체 지지구조에 관한 것으로, 특히 비용이 절감되고 배기가스의 온도변화에 적절히 대응하면서 담체를 지지할 수 있도록 된담체 서포터가 적용된 자동차 촉매컨버터의 담체 지지구조에 관한 것이다.The present invention relates to a carrier support structure of an automobile catalytic converter, and more particularly, to a carrier support structure of an automobile catalyst converter to which a carrier supporter, which is capable of supporting a carrier while reducing costs and appropriately responding to a temperature change of exhaust gas, is applied.

일반적으로 자동차의 배기계는 도 1에 도시된 바와 같이, 배기매니폴드에 연결된 배기관(10)에 소음저감을 위한 머플러(20;서브머플러, 30;메인머플러)가 설치되고, 이 머플러의 앞쪽에 공해물질제거를 위한 촉매컨버터(40)--차종에 따라서는 배기매니폴드에 직접 설치되는 경우도 있다.--가 설치된 구조로 이루어진다.In general, as shown in FIG. 1, an exhaust system of a vehicle is provided with a muffler 20 (sub muffler, 30; main muffler) for noise reduction in an exhaust pipe 10 connected to an exhaust manifold. The catalytic converter 40 for removing the substance, which is installed directly in the exhaust manifold depending on the type of vehicle.

상기 촉매컨버터(40)는 도 2에 도시된 바와 같이, 쉘(41)의 내부에 입상 또는 격자상의 알루미나에 촉매작용을 하는 물질(백금, 로듐, 파라듐)이 부착된 담체(42)가 내장된 구조로 이루어진 것이며, 이 담체(42)를 배기가스가 통과하면서 유해성분인 일산화탄소(CO)와 탄화수소(HC) 및 질소산화물(NOx)이 무해한 질소(N2), 이산화탄소(CO2), 물(H2O)로 변환되어 배기가스가 정화된다.As shown in FIG. 2, the catalytic converter 40 includes a carrier 42 having a substance (platinum, rhodium, or palladium) attached thereto, which catalyzes granular or lattice-shaped alumina inside the shell 41. Exhaust gas passes through the carrier 42, and the harmful components of carbon monoxide (CO) and hydrocarbons (HC) and nitrogen oxides (NO x ) are harmless nitrogen (N 2 ), carbon dioxide (CO 2 ), It is converted into water (H 2 O) to purify the exhaust gas.

상기 담체(42)는 도 3에 도시된 바와 같이, 서포터(43)에 둘러 싸여진 상태로 상기 쉘(41)에 내장되는데, 이 서포터(43)는 담체(42)를 보호하고, 배기가스 온도에 의한 쉘(41) 및 담체(42)의 수축과 팽창에 대응하면서 담체(42)를 쉘(41)의 내부에서 안정적으로 지지하는 역할을 한다.The carrier 42 is embedded in the shell 41 in a state surrounded by the supporter 43, as shown in FIG. 3, which protects the carrier 42 and at an exhaust gas temperature. Corresponding to the contraction and expansion of the shell 41 and the carrier 42 by the support serves to stably support the carrier 42 in the shell 41.

한편, 정화율 향상을 위한 담체(42)의 셀(sell)수 증가에 따라, 소프트 캐닝(soft canning)을 위하여 현재 서포터(43)의 재질은 버미컬라이트(vermiculite)에서 알루미나 섬유(alumina fiber)로 변경되어 적용되고 있다.On the other hand, with the increase in the number of cells (sell) of the carrier 42 for improving the purification rate, the material of the current supporter 43 for soft canning (vermiculite) in the alumina fiber (alumina fiber) Has been changed and applied.

그러나, 알루미나 섬유는 그 가격이 매우 고가여서 비용부담이 증가되는 문제점이 있었다.However, alumina fiber has a problem that the cost is increased because the price is very expensive.

이에 본 발명은 상기와 같은 문제점을 해결하기 위하여 발명된 것으로, 온도변화에 따른 쉘 및 담체의 수축과 팽창에 민감하게 대응하면서 담체를 안정적으로 지지할 수 있으면서 그 적용 가격도 저렴한 서포터를 갖춘 자동차 촉매컨버터의 담체 지지구조를 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the above problems, while being sensitive to the contraction and expansion of the shell and the carrier according to the temperature change, it is possible to stably support the carrier, and the vehicle catalyst having a low support price. The object is to provide a carrier support structure for the converter.

상기와 같은 목적을 달성하기 위한 본 발명은, 담체를 둘러싼 서포터가 버미컬라이트와 세라믹 섬유의 혼합물로 이루어지고, 이 서포터는 상기 담체가 내장되는 쉘의 내측표면에 대하여 담체를 지지하도록 된 구조로 이루어진다.The present invention for achieving the above object, the supporter surrounding the carrier is made of a mixture of vermiculite and ceramic fibers, the supporter is structured to support the carrier against the inner surface of the shell in which the carrier is embedded Is done.

이하, 본 발명을 첨부된 도면을 참조하여 설명한다.Hereinafter, the present invention will be described with reference to the accompanying drawings.

도 4는 본 발명에 따른 담체 지지구조가 적용된 촉매컨버터의 종단면도로서, 본 발명은 쉘(41)의 내부에 촉매물질이 부착된 담체(42)가 내장되되, 이 담체(42)는 서포터(43)에 의해 둘러 싸여져 있으며, 이 서포터(43)의 양측에는 시일(seal;44)이 구비되는 구조로 이루어진다.4 is a longitudinal cross-sectional view of a catalyst converter to which a carrier support structure is applied according to the present invention. The present invention includes a carrier 42 having a catalyst material attached to the inside of the shell 41, wherein the carrier 42 is a supporter ( It is enclosed by 43, and it consists of a structure in which the seal 44 is provided in the both sides of this supporter 43. As shown in FIG.

여기서, 상기 서포터(43)는 버미컬라이트(vermiculite)와 세라믹 섬유(ceramic fiber)의 혼합물로 이루어지며, 그 재질 특성은 다음과 같다.Here, the supporter 43 is made of a mixture of vermiculite and ceramic fiber, the material properties are as follows.

항 목Item 종 래Species 본 발명The present invention 유기휘발물질(LOI)Organic Volatiles (LOIs) 8∼16 %8-16% 6∼13 %6 to 13% 알루미나(Al2O3)Alumina (Al 2 O 3 ) 84∼92 %84-92% 46∼59 %46 to 59% 버미컬라이트(vermiculite)Vermiculite 0 %0 % 32∼43 %32-43%

상기 표에서와 같이 종래에 비하여 본 발명에 따른 서포터(43)는 고가재질인알루미나의 함량이 약 절반으로 줄고, 그 부족분이 저가재질인 버미컬라이트에 의해 충당되고 있다.As shown in the table, the supporter 43 according to the present invention is reduced to about half the content of alumina, which is expensive, and the shortage thereof is covered by vermiculite, which is a low cost material.

따라서, 배기가스의 유동적인 온도변화에 따른 쉘(41) 및 담체(42)의 팽창 및 수축에 민감하게 대응하면서 담체(42)를 지지함은 물론, 소프트캐닝을 위해 채택되었던 알루미나가 다량 잔존함으로써 종래와 같이 쉘(41) 및 담체(42)의 체적변화를 수용하면서 담체(42)를 안정적으로 지지할 수 있고, 캐닝(canning)시 작업성은 용이하게 유지되며, 이에 더하여 가격은 약 30∼40 % 정도 절감되게 된다.Therefore, while supporting the carrier 42 while being sensitive to the expansion and contraction of the shell 41 and the carrier 42 according to the fluctuations in the fluctuation of the exhaust gas, a large amount of alumina remaining for soft canning remains. The carrier 42 can be stably supported while accommodating volume changes of the shell 41 and the carrier 42 as in the related art, and workability can be easily maintained during canning, and the price is about 30 to 40. % Savings.

한편, 상기 서포터(43)의 양 옆에 위치된 시일(44)은 배기가스가 담체(42) 이외의 부분으로 통과하는 것을 방지하고, 서포터(43)의 담체(42) 지지상태를 더욱 견고히 해 주는 역할을 한다.On the other hand, the seals 44 positioned on both sides of the supporter 43 prevent the exhaust gas from passing through portions other than the carrier 42, and further strengthen the support 42 of the supporter 43. Role.

이상 설명한 바와 같이 본 발명에 따르면, 촉매컨버터의 담체 서포터로서 요구되는 성질은 그대로 유지하면서도 가격은 저렴한 서포터가 구비됨으로써 촉매컨버터의 제작비용이 저감되는 효과가 있다.As described above, according to the present invention, by providing a supporter having a low cost while maintaining the properties required as a carrier supporter of the catalyst converter, the manufacturing cost of the catalyst converter can be reduced.
