To suppress fine dust accumulated in a filter from separating from the filter and being dispersed when direction of water flowing in the periphery of a fine dust capture device becomes the direction reverse to advancing of a vessel.SOLUTION: A fine dust capture device 21 includes a water inlet 26 provided on a front end side of a body part 22, a rear wall part 27 sealing a rear end side of the main part 22, a first passage 31 and a second passage 32 stretching in the front to back direction in the main part 22, a drain chamber 38 provided in between respective rear end parts and rear wall parts 27 of the first passage 31 and the second passage 32 in the main body 22, an outlet 39 provided on the rear wall part 27, and a filter 40 provided in the first passage 31. Respective rear end sides of the first passage 31 and the second passage 32 open into the drain chamber 38, and the outlet 39 does not face an opening of the first passage 31 opening into the drain chamber 38 but is arranged in a position facing an opening of the second passage 32 opening into the exhaust chamber 38 in the rear wall part 27.SELECTED DRAWING: Figure 7
【課題】微小塵捕捉装置の周囲を流れる水の方向が船舶の前進時とは逆の方向になったとき、フィルタに蓄積された微小塵がフィルタから分離して拡散することを抑制する。【解決手段】微小塵捕捉装置21は、本体部22の前端側に設けられた取水口26と、本体部22の後端側を閉塞する後壁部27と、本体部22内を前後方向に伸長した第1の通路31および第2の通路32と、本体部22内において、第1の通路31および第2の通路32のそれぞれの後端部と後壁部27との間に設けられた排水室38と、後壁部27に設けられた排出口39と、第1の通路31に設けられたフィルタ40とを備え、第1の通路31および第2の通路32のそれぞれの後端側は排水室38内に開口し、後壁部27において、排出口39は、排水室38内に開口した第1の通路31の開口部とは対向せず、排水室38内に開口した第2の通路32の開口部と対向する位置に配置されている。【選択図】図7
