PROBLEM TO BE SOLVED: To provide a device which eliminates filter clog that causes an obstacle for any system and settles a slurry clarification countermeasure for an ultraviolet sterilization device.SOLUTION: A cyclone separator body 1 comprises a stationary impeller 3-1 and is provided with a separation inner cylinder 6 and a sedimentation tank 2 at the bottom. Water introduced into the separator body from a ballast water inlet pipe 4 is changed into a swirling flow by the stationary impeller to turn to the bottom sedimentation tank while swirling along the inner wall of the separator body. The ballast water has such a structure as to increase a flow speed and obtain a large centrifugal force when passing the stationary impeller. A solid material in seawater is separated to the inner wall side by this centrifugal force and then descends along this inner wall to descend into the bottom sedimentation tank. A swirling flow at the body center becomes purified clean water and is therefore fed to a sterilizer via the separation inner cylinder 6 and a ballast water outlet pipe 5.

    【課題】いずれのシステムにおいても障害となるフィルターの目詰まりをなくすと共に、紫外線殺菌装置用として泥水の浄化対策の解決をも行う装置を提供する。【解決手段】サイクロンセパレーター本体1は、固定羽根3−1を備え、分離内筒6と下部に沈降タンク2を設けた。バラスト水入口管4からセパレーター本体へ導入された水は固定羽根により旋回流に変えられ、セパレーター本体の内壁に沿って旋回しながら下部沈降タンクへと向かう。バラスト水は固定羽根通過時、流速を増加し大きな遠心力を得る構造となっており、海水中の固形物はこの遠心力により本体内壁側へと分離され、その後この内壁に沿って下降し、下部沈降タンク内へと下降する。本体中央部の旋回流は浄化された清浄水となるため、分離内筒6,バラスト水出口管5を経て殺菌装置へと送出される。【選択図】図1
