Description
본 발명은 자동차 배기가스 처리장치에 관한 것으로서, 보다 상세하게는 자동차에 탑재된 직류전원을 이용한 플라즈마를 발생시켜 자동차 배기가스를 정화하는 자동차 배기가스 처리장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile exhaust gas treatment apparatus, and more particularly, to an automobile exhaust gas treatment apparatus that generates plasma using a DC power source mounted on an automobile to purify automobile exhaust gas.
최근 날로 심각해지고 있는 대도시의 대기오염 문제는 80% 이상이 자동차에서 배출되는 오염물질에 기인한다.The problem of air pollution in big cities, which is becoming more serious in recent days, is due to pollutants emitted by automobiles more than 80%.
자동차에서 배출되는 오염물질은 인간의 주변환경 및 건강에 직접적으로 유해한 영향을 미치거나 탄화수소와 질소산화물의 경우에는 대기 중에서 태양광선과 반응하여 2차 오염물질인 O3을 생성하기도 한다. 즉, 자동차의 배기가스는 자동차의 엔진 내에서 이루어지는 자동차의 연소에 의한 것으로서, 자동차 연소에 의하여 발생되는 대기오염물질로는 CO, NOx, HC을 비롯한 여러 종류의 VOCs(휘발성유기화합물)등이 배출된다. 이러한 대기오염물질은 직접적으로 인체에 유해할 뿐만 아니라 대기 중으로 배출되어 태양광선에 의한 광화학 반응으로 인하여 오존을 형성하는 전구물질이 되기도 한다.Pollutants emitted from automobiles have a direct detrimental effect on humans' surroundings and health, or in the case of hydrocarbons and nitrogen oxides, react with sunlight in the air to produce secondary pollutants, O 3 . In other words, the exhaust gas of automobiles is caused by the combustion of automobiles in the engines of automobiles, and various kinds of VOCs (volatile organic compounds) including CO, NOx, HC are emitted as air pollutants generated by automobile combustion. do. These air pollutants are not only directly harmful to the human body, but are also emitted into the atmosphere and become precursors that form ozone due to photochemical reactions caused by sunlight.
이러한 자동차 배기가스를 처리하기 위한 종래의 처리장치에는 직접불꽃방식과, 촉매장치에 의한 방식이 사용되고 있으며, 상기의 직접불꽃 방식은 공기펌프에 의하여 공급되는 2차 공기와 배기가스의 일부를 연소실로 유도한 후 다시 연소하여, CO와 HC를 제거하는 것으로, 이 장치의 연소반응은 비교적 높은 온도에서 이루어지므로 열 교환기와 보조연료의 공급으로 연소를 지속시킨다. 이 장치는 각 부분에서 높은 온도가 발생하므로 양질의 내열재를 써야하고, 보조연료를 사용하므로 연료의경제적인 면에서 바람직하지 않고 장치가 커지는 단점이 있고, 촉매장치에 의한 방식은 촉매를 사용하여 배기가스 중의 불완전 연소분을 제거하는 것으로, 배기가스와 2차 공기의 혼합가스를 촉매층에 통과시켜 각각 산화, 환원, 삼원 촉매반응을 일으켜 HC, CO, NOx 등을 제거하는 것으로, 각각의 오염물질에 대한 촉매를 선택하여야 하고, 촉매의 대부분이 고가이며, 처리 시 압력손실이 발생하는 단점이 있다.In the conventional treatment apparatus for treating such vehicle exhaust gas, a direct flame method and a method using a catalyst device are used. The direct flame method uses a part of secondary air and exhaust gas supplied by an air pump to a combustion chamber. By induction and combustion again, the removal of CO and HC, the combustion reaction of the device is carried out at a relatively high temperature, so the combustion is continued by the supply of heat exchanger and auxiliary fuel. This device has to use high quality heat resistant material because high temperature is generated in each part, and it is disadvantageous in terms of fuel economy because of the use of auxiliary fuel, and the device becomes large. Incomplete combustion of exhaust gas is removed, and mixed gas of exhaust gas and secondary air is passed through the catalyst layer to cause oxidation, reduction, and three-way catalytic reaction to remove HC, CO, NOx, and the like. The catalyst should be selected for, most of the catalyst is expensive, there is a disadvantage that the pressure loss occurs during processing.

상기와 같은 점을 감안하여 안출한 본 발명의 목적은 자동차 내의 전원을 이용하여 플라즈마를 생성하고, 상기 플라즈마에 의해 배기가스에 포함된 오염물질을 정화할 수 있는 자동차 배기가스 처리장치를 제공함에 있다.SUMMARY OF THE INVENTION An object of the present invention devised in view of the above is to provide a vehicle exhaust gas treatment apparatus capable of generating plasma using a power source in an automobile and purifying contaminants contained in exhaust gas by the plasma. .
