<p><P>PROBLEM TO BE SOLVED: To provide an exhaust emission control device capable of decomposing specific components contained in treated gas by efficiently utilizing high frequency energy with simple constitution, and excelling in mountability. <P>SOLUTION: The exhaust emission control device includes at least a high frequency oscillating means 30 oscillating a high frequency RF, and a waveguide 10 transmitting the high frequency RF oscillated from the high frequency generating means 30. The passage directions 11, 12 of exhaust passages through which treated exhaust flows, are made coincident with the transmitting direction of the waveguide 10 to interpose the waveguide 10 in the exhaust passages 11, 12. The treated exhaust permeates an inlet side opening of the waveguide 10 communicating with the before-treatment exhaust passage 11 through which exhaust before treated flows, and an outlet side opening of the waveguide 10 communicating with the treated exhaust passage 12 through which the treated exhaust flows. Gas permeable high frequency reflecting walls 20, 21 are provided for reflecting the high frequency RF oscillated from the high frequency generating means 30, and the waveguide 10 is set to such a length that the standing waves of the high frequency RF are formed between the gas permeable high frequency reflecting walls 20, 21 provided at both ends of the waveguide 10. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
