<P>PROBLEM TO BE SOLVED: To provide an exhaust emission control device allowing simplification of a structure. <P>SOLUTION: A breathable cylindrical grease filter 23 is rotatably disposed inside a main body 22 such that the grease filter 23 closes an inflow port 25 of the main body 22. A water supply jetting port of a water supply jetting pipe 36 is provided opposite to the grease filter. A temperature sensing sensor 48 senses a temperature of an exhaust air 5. When the temperature of the exhaust air 5 is not less than a preset prescribed temperature, water 44 is jetted toward the grease filter 23 from the water supply jetting port while a deceleration motor 34 rotates the grease filter 23. The water 44 and a washing liquid 49 stored in a washing tank 24 form a liquid film on the peripheral face of the grease filter 23. Because the liquid film of the peripheral face of the grease filter 23 can certainly prevent transmission of flame without independently providing a fireproof damper, the structure can be simplified. <P>COPYRIGHT: (C)2004,JPO |
