Description

자동차 배기가스 재 연소처리장치Automobile Exhaust Reburn Treatment System

최근의 대기오염은 그 심각도가 점차 증대되므로서 국민의 건강 및 자연생태계를 심각하게 위협하고 있는 바 대기오염의 주원인이 되는 것으로 자동차 배기가스를 들 수 있는데 자동차 엔진으로부터 배출되는 배기가스는 완전연소가 되지 않을 뿐 아니라 엔진의 성능에 따라서 매연의 배출정도가 많은 차이가 있으나 아무리 연료의 연소상태가 양호하다 할지라도 100% 완전연소가 될 수 없고 따라서 자동차의 배기가스는 인체에 극히 유해한 각종 공해물질이 혼재된 상태에서 배기되게 되어 대기를 오염시키게 되므로 본 발명은 이와 같은 배기가스를 별다른 부가장치없이 2차 연소시키므로서 완전연소에 가깝게 각종 공해물질을 연소시키는 한편 2차 연소처리를 한 이후에도 잔존하는 유해물질은 미세한 필터장치를 거쳐서 여과한 다음 청정공기만을 대기 중으로 배기시키므로서 대기오염을 현저하게 줄일 수 있도록 함에 본 발명의 목적이 있다.Recent air pollution is a serious threat to the health and natural ecosystems of the public as its severity is gradually increasing. Car exhaust is one of the main causes of air pollution. Not only does the exhaust emission vary greatly depending on the engine's performance, but no matter how good the combustion condition of the fuel is, it can not be 100% completely burned. Since the exhaust gas is mixed in a mixed state to contaminate the air, the present invention secondary combustion of such exhaust gas without any additional equipment, thereby burning various pollutants close to complete combustion while remaining harmful after the second combustion treatment. The material is filtered through a fine filter and then clean air only The purpose of the present invention as to be standing because the exhaust into groups significantly reduce air pollution.

본 발명은 가솔린, 경유 등을 연료로 하여 동력을 발생시키는 각종 내연기관 등에서 필연적으로 발생하는, 사람을 포함한 자연생태계를 파괴하는 대기오염의 주원인인 불완전연소 배기가스를 정화하는 정화장치에 속하는 분야에 대한 것으로 현재경유를 연료로 하는 자동차에서 발생되는 배기가스를 정화하는 장치로서 첨부한 도면 도1에 그 개념을 도시한 고안이 제안되어 있는 바 이 고안의 개요는 엔진 (1)으로부터 나오는 불완전연소 배기가스를 2대의 배기가스 연소장치로서 교대로 재연소시키므로서 배기가스의 유해물질을 최소화하고자 한 것으로서 불완전연소 배기가스를 2대중의 1대의 연소장치(A)가 엔진으로부터 나오는 불완전연소가스를 여과, 포집하는 동안 다른 1대의 연소장치(B)는 별도의 열원(2)으로부터 고온의 열을 연소장치(B) 내부로 공급하여 2차 연소시켜서 머플러(3)를 통하여 배기되도록 하되 연소장치(A)와 (B)를 교대로 여과포집, 재연소를 시키도록 하고 있다.The present invention is in the field belonging to the purification apparatus for purifying incomplete combustion exhaust gas, which is the main cause of air pollution that destroys natural ecosystems including humans, inevitably generated in various internal combustion engines that generate power by using gasoline, diesel, and the like as fuel. As a device for purifying exhaust gas generated from a vehicle currently fueled by diesel fuel, a design showing the concept is proposed in FIG. 1. The outline of the design is an incomplete combustion exhaust from the engine 1. In order to minimize the harmful substances in the exhaust gas by alternately re-burning the gas as two exhaust gas combustion devices, one combustion device (A) of two incomplete combustion exhaust gas filters the incomplete combustion gas from the engine. During the capture, the other combustor (B) draws high temperature heat from a separate heat source (2) into the combustor (B). By supplying the secondary combustion and exhausting it through the muffler 3, the combustion apparatuses A and B are alternately filtered and reburned.

상기와 같은 종래의 배기가스 정화장치는 엔진으로부터 1차로 연소되는 머플러(3)를 통하여 대기중으로 방출되는 배기가스를 2대의 2차연소장치에 교대로 유입시켜 별도의 연소열원을 구비하여 2차 연소시키는 구조로 되어 있는데 자동차에 내장되어 있는 바테리의 전력을 이용하여 2차 연소열원으로 사용하거나 연소버너를 별도로 설치하여 이 버너에서 발생되는 열로 2차 연소시키게 됨에 따라 장치의 부가에 따르는 제작비용의 증가와 부피와 무게가 그만큼 증대되는 문제점이 있으며 장치가 복잡하여 고장의 우려가 크고 이와같은 연소장치와 별도로 고온의 플라즈마를 발생시켜 불완전연소가스를 연소정화처리하는 방법이 있으나 이 또한 플라즈마 발생장치가 고가이며 복잡하여 제작자체가 용이하지 못하였다.The conventional exhaust gas purification apparatus as described above alternately flows exhaust gases discharged into the atmosphere through two mufflers 3, which are primarily combusted from an engine, to two secondary combustion apparatuses to provide secondary combustion with separate combustion heat sources. As the secondary combustion heat source is used by using the electric power of the battery built in the car or the combustion burner is installed separately, the secondary combustion is performed by the heat generated from this burner. There is a problem in that the volume and weight are increased, and there is a high risk of failure due to the complexity of the device, and there is a method of generating a high-temperature plasma and combusting the incomplete combustion gas separately from such a combustion device, but the plasma generation device is also expensive. The production itself was not easy because of the complexity.

At this time, the tip of the heat pipe (H) provided on the inlet pipe 21 side receives the high temperature heat of the exhaust gas and is a liquid thermal conductive material (Hg, K, Na, naphthalene, etc.) enclosed in the heat pipe (H). This vaporization is instantaneously endothermic and the inside is vacuumed, and the heat is transferred to the other end of the heat pipe (H) without heat loss from the outside without heat loss. While being liquefied and induced by the capillary phenomenon along the capillary layer 11 installed on the inner circumferential surface of the heat pipe H, it is moved to the evaporation part side of the heat pipe H and rapidly thermally evaporates while absorbing high heat from the outside. This is performed repeatedly repeatedly, whereby the primary exhaust gas is introduced into the combustion tube 22 through the inlet pipe 21 and at a high temperature of 400 ° C. to 600 ° C. that generates heat from the heat pipe H at the same time. Hazardous combustibles of the primary exhaust gas are secondary burned, and the residual gas generated in the secondary combustion is discharged to the outside of the secondary combustion device. The side wall 25 of the combustion pipe 22 is sealed and the side wall 25 ) And the one side of the tubular filter 24, the secondary combustion gas passes through the tubular filter 24, and harmful substances that may remain after the secondary combustion are filtered to micro units or less, so that only the clean air is discharged to the exhaust pipe 26. It is discharged through the outside.
