<P>PROBLEM TO BE SOLVED: To highly efficiently collect particles in a mist state contained in a discharged fluid such as oily smoke, particularly oil and fat and dust generated in a kitchen. <P>SOLUTION: In an improved grease filter X, blades 1 (2, 3) having approximately symmetric V-shaped cross-sectional shapes are arranged at equal intervals to form ventilation paths 4, (5, 6) having the blades 1 (2, 3) as partitions and a discharge fluid is introduced from the opened starting ends of the ventilation paths 4 (5, 6) to curve the flow of the fluid at an acute angle in the middle parts of the paths and the fluid is guided unidirectionally while being turned in the flowing direction and released from the open terminal ends. The partitions of the ventilation paths 4 (5, 6) are respectively curved via bent parts 8 to the introduction sides (inlets) and the open sides (outlets) and the cross-section width of the ventilation paths (4 to 5) on the upstream side from the introduction sides to the bent parts 8 is gradually decreased, "flare-contracted", and the the cross-section width of the ventilation paths (6 to 7) on the downstream side from the bent parts 8 to release sides is gradually increased, "flare-diffused". <P>COPYRIGHT: (C)2004,JPO |
