<P>PROBLEM TO BE SOLVED: To provide an air supply water filtering device having simplified construction for reducing manufacturing and operating costs, and an air supply cleaning method. <P>SOLUTION: The air supply water filtering device comprises an air supply duct 14, a water storage part 16, a partition wall 12 and a filter plate 13. The air supply duct 14 has a suction port 14a and a supply port 14b. The water storage part 16 is provided in the air supply duct 14 between the suction port 14a and the supply port 14b. The partition wall 12 is arranged in the air supply duct 14 at a gap 18 to the level of water stored in the water storage part 16, through which air is permeable to send up spray of water, in the form of interruption between the suction port 14a and the supply port 14b. The filter plate 13 having a plurality of plate materials 11a alternately arranged at an air-permeable gap is provided above the water storage part 16 in the form of blocking the air supply duct 14. The filter plate 13 can interrupt a spray of water to be sent up by air permeation through the gap 18, and it is air permeable. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
