<p><P>PROBLEM TO BE SOLVED: To provide a purification device removing odor and collecting dust held in exhaust gas emitted from a traveling vehicle engine and efficiently removing CO, NOX dust with a simple structure. <P>SOLUTION: This device eliminates burning concentration by electric heat firepower and gas firepower, and uses two kinds of devices of an electric power heater combustor and a gas firepower combustor. A flange metal fitting 1 is connected to an engine exhaust port to take exhaust gas in. Air oxygen quantity is adjusted by turning movement of an air introduction adjustment rotary ring device 3 and is merged with exhaust gas to reduce exhaust gas temperature. Exhaust gas is guided to an electric heating heater chamber 7 and is burned. Exhaust gas flow is cooled by injection nozzle water of a cooling chamber and humidity is maintained. Remaining toxic material CO, NOX dust or the like is efficiently adsorbed and filtered further by cylindrical cotton fiber fabric provided in a bellows pipe. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
