Description
본 고안은 엔진으로부터 배출되는 질소산화물 및 유해가스를 다단식으로 형성된 코로나반응기를 이용하여 제거하는 정화장치에 관한 것으로서, 더욱 자세하게는 촉매장치를 코로나반응기와 유기적으로 결합시켜 소요에너지를 극소화할 뿐만 아니라 배기가스 처리온도영역에도 구애받지 않는 촉매일체형 다단식 코로나반응기에 관한 것이다.The present invention relates to a purifier that removes nitrogen oxides and harmful gases discharged from an engine using a multi-stage corona reactor, and more specifically, combines the catalytic device with a corona reactor organically to minimize the required energy and exhaust the exhaust gas. It relates to a catalyst integrated multi-stage corona reactor regardless of the gas treatment temperature range.
배기가스의 유해성분을 정화시키기 위한 종래의 방법으로는 3원촉매 등의 촉매장치를 배기관에 장착하여 유해가스를 산화 또는 환원시킴으로써 정화시키는 방법이 주로 이용되었다.As a conventional method for purifying harmful components of exhaust gas, a method of purifying by oxidizing or reducing harmful gases by attaching a catalyst device such as a three-way catalyst to an exhaust pipe is mainly used.
다른 방법으로는 고전압에 의한 코로나방전으로 플라즈마 화학반응을 일으키는 코로나반응기를 이용하여 유해성분을 산화 또는 환원시키는 방법이 이용되고 있는데, 본 출원인은 특허출원 제95-49666호와 제95-49667호에서 고전압에 의한 코로나방전으로 플라즈마를 형성하는 코로나반응기를 다단으로 조립한 다단식 코로나반응기를 제안한 바 있으며, 이것은 다수의 단에서 코로나방전을 시킨 상태에서 배출가스를 연속적으로 통과시킴으로써 배출가스 유해성분의 제거효율을 극대화시킨 장치이다.As another method, a method of oxidizing or reducing harmful components by using a corona reactor that generates a plasma chemical reaction by high voltage corona discharge is used, and the applicants in Korean Patent Application Nos. 95-49666 and 95-49667 A multi-stage corona reactor has been proposed in which multiple corona reactors that form plasma by corona discharge due to high voltage are assembled in multiple stages, which efficiently removes harmful components of the exhaust gas by continuously passing the exhaust gas in a corona discharge state in multiple stages. The device maximized.
배기가스를 정화시키기 위하여 촉매장치를 이용할 경우 가솔린엔진의 배기가스를 정화시키기 위한 촉매장치는 개발되어 있으나, 디젤엔진의 배기가스를 정화시키기 위한 촉매장치는 아직도 개발 중에 있으며 상용화된 기술이 없다.In the case of using a catalytic apparatus for purifying exhaust gas, a catalytic apparatus for purifying exhaust gas of a gasoline engine has been developed, but a catalytic apparatus for purifying exhaust gas of a diesel engine is still under development and there is no commercialized technology.
디젤엔진용 촉매장치 개발에 있어서의 문제점은 다량의 산소가 존재하는 배기가스에 대하여 사용할 수 있는 촉매의 개발이 어렵다는 점과 촉매반응이 활성화될 수 있는 온도영역이 제한되는 점 등이다.Problems in the development of a catalytic device for diesel engines include the difficulty in developing a catalyst that can be used for exhaust gas in which a large amount of oxygen exists and the temperature range in which the catalytic reaction can be activated.
특히, 온도에 대한 문제점은 적절한 촉매가 개발된다 하더라도 해결해야 할 과제이기 때문에 촉매활성이 취약한 온도영역인 저온영역에서 촉매를 대체할 수 있는 기술이 필요한 실정이다.In particular, since the problem of temperature is a problem to be solved even if an appropriate catalyst is developed, there is a need for a technology capable of replacing the catalyst in a low temperature region where the catalytic activity is weak.
또한, 상기에서 언급한 코로나방전을 이용한 정화장치는 소요에너지가 과다하게 든다는 취약점 때문에 상용화에 문제가 있는 것으로 알려져 있다. 특히, 디젤자동차와 같이 이동원에 적용할 경우 별도의 에너지원이 마련되지 못하면 과다한 소요에너지로 인하여 적용 자체가 불가능해진다는 문제점이 있다.In addition, the purification apparatus using the corona discharge mentioned above is known to have a problem in commercialization due to the vulnerability of excessive energy consumption. In particular, when applied to a mobile source, such as a diesel car, if a separate energy source is not provided, there is a problem that the application itself is impossible due to excessive required energy.
또한, 상기 촉매장치와 코로나반응기를 접목시킨 배기가스 정화장치를 개발하기 위한 노력이 있었으나 성공한 사례는 없었으며, 가장 최근에 발표된 사례의 경우 각각을 단순히 병렬로 연결시켜 사용하는 정도의 수준에 머무르고 있는 실정이다.In addition, efforts have been made to develop an exhaust gas purifying device incorporating the catalytic device and the corona reactor, but there have been no successful cases. In the case of the most recently published case, each is simply connected to each other in parallel. There is a situation.
본 고안은 이러한 문제점들을 해결하기 위한 것으로서, 본 고안의 목적은 촉매장치를 코로나반응기와 유기적으로 결합시켜 소요에너지를 극소화한 고효율의 촉매일체형 다단식 코로나반응기를 제공하는데 있다.The present invention is to solve these problems, an object of the present invention is to provide a high-efficiency catalyst-integrated multi-stage corona reactor that minimizes the energy required by organically combining the catalyst device with the corona reactor.
본 고안의 다른 목적은 배기가스의 처리가 처리온도영역에 의해 구애받지 않고 온도영역과 관계없이 처리가능한 촉매일체형 다단식 코로나반응기를 제공하는데 있다.Another object of the present invention is to provide a catalyst-integrated multi-stage corona reactor capable of treating the exhaust gas irrespective of the treatment temperature range and irrespective of the temperature region.

Is provided.
상기 카트리지(50)는 본 고안의 일 실시예인 촉매일체형 다단식 코로나반응기(1)를 구성하는 기본단위이며, 배기가스의 유량에 따라 최적의 단수로 적층될 수 있다.The cartridge 50 is a basic unit constituting the catalyst-integrated multi-stage corona reactor 1, which is an embodiment of the present invention, and may be stacked in an optimal stage according to the flow rate of the exhaust gas.
또한, 적층된 카트리지(50)들은 카트리지설치판(60)에 의해 흡기관(70) 및 배기관(80)과 결합되어 촉매일체형 다단식 코로나반응기(1)를 형성한다.In addition, the stacked cartridges 50 are combined with the intake pipe 70 and the exhaust pipe 80 by the cartridge mounting plate 60 to form the catalyst integrated multi-stage corona reactor 1.
다음에, 이와 같이 구성되어 있는 본 고안의 일 실시예에 의한 촉매일체형 다단식 코로나반응기의 작용을 도 3를 참조하여 상세히 설명한다.Next, the action of the catalyst-integrated multi-stage corona reactor according to one embodiment of the present invention configured as described above will be described in detail with reference to FIG. 3.
배기가스가 흡기관(70)을 통하여 본 고안의 일 실시예인 다단식 코로나반응기(1)에 유입되면 배기가스는 각 단의 카트리지(50)내에 설치된 방전극판(30)과 상대전극판(10)사이의 코로나방전에 의해 플라즈마화학반응을 겪게 된다. 즉, 배기가스 중의 NO는 주로 산화반응에 의해 NO2로 된다.When the exhaust gas flows into the multi-stage corona reactor 1 according to the embodiment of the present invention through the intake pipe 70, the exhaust gas flows between the discharge electrode plate 30 and the counter electrode plate 10 installed in the cartridge 50 at each stage. Corona discharge of to undergo a plasma chemical reaction. That is, NO in the exhaust gas is mainly to NO 2 by the oxidation reaction.
다음에, 촉매형 방전극설치판(40)에 의해 촉매작용을 받게 되는데, 촉매는 주로 NO2를 무해한 기체로 분해하는 기능을 담당한다.Next, the catalyst type discharge electrode mounting plate 40 is subjected to catalysis, and the catalyst mainly functions to decompose NO 2 into a harmless gas.
상기와 같은 과정을 수행하는 다단의 카트리지(50)들을 연속적으로 통과하게 되면 2차적인 오염물질의 생성없이 배기가스를 완전히 무해한 기체로 분해하여 배출할 수 있다.Continuously passing through the cartridge 50 of the multi-stage to perform the above process can be exhausted by decomposing the exhaust gas completely harmless gas without the generation of secondary pollutants.
또한, 시동초기와 같이 촉매가 활성화되지 않은 저온영역에서는 코로나방전에 의해 유해성분을 주로 처리하고 촉매의 온도가 배기가스에 의해 상승하여 활성화된 후에는 촉매에 의해 처리하게 되어 촉매의 활성화 후에는 코로나반응기의 작동율이 낮아지므로 코로나방전에 의한 소비에너지를 저감시킬 수 있다.In addition, in the low temperature region in which the catalyst is not activated, such as at the beginning of the process, the harmful components are mainly treated by corona discharge, and after the catalyst temperature is increased by the exhaust gas and activated, it is treated by the catalyst. Since the operation rate of the reactor is lowered, it is possible to reduce energy consumption by corona discharge.
또한, 상기 카트리지(50)는 적층하는 단수를 변화시킬 수 있으므로 최종적인 유해물질의 저감효율에 따라 최적의 상태로 가변시킬 수 있다.In addition, since the cartridge 50 can change the number of layers to be stacked, it can be changed to an optimal state according to the reduction efficiency of the final harmful substances.
앞에서 설명한 바와 같이 본 고안의 일 실시예인 촉매일체형 다단식 코로나반응기에 의하면, 방전극설치판이 다공성의 담체를 기초로 한 촉매로 형성되어 있어서 촉매장치가 코로나반응기와 유기적으로 결합되므로 소요에너지를 극소화할 수 있을 뿐만 아니라 배기가스의 처리가 처리온도영역에 의해 구애받지 않고 온도영역과 관계없이 처리가능하다는 효과가 있다.As described above, according to the catalyst integrated multi-stage corona reactor according to one embodiment of the present invention, since the discharge electrode mounting plate is formed of a catalyst based on a porous carrier, the catalyst device is organically coupled to the corona reactor, thereby minimizing required energy. In addition, there is an effect that the treatment of the exhaust gas can be processed irrespective of the processing temperature range regardless of the temperature range.
