バラスト水処理装置
Document Type and Number:
Japanese Patent JP6726414
Kind Code:
B2
Abstract:
To provide a ballast water treatment apparatus that can eliminate the possibility that the sterilizing agent supply device, and the like, may be adversely affected by the reduction reaction heat that is generated in the detoxication of the sterilizing agent residue. The ballast water treatment apparatus includes a sterilizing agent supply device (20) that supplies a chlorine-based sterilizing agent into the inside of a ballast water piping (3) through which ballast water is passed toward a ballast tank (2); a reduction agent supply device (30) that supplies a reduction agent that is reacted with the chlorine-based sterilizing agent into the inside of the ballast water piping (3); a first piping (22) that transfers the chlorine-based sterilizing agent that has remained in the sterilizing agent supply device (20) into the inside of the ballast water piping (3); a second piping (32) that transfers the reduction agent into the inside of the ballast water piping (3); and an injection part (7) that injects the chlorine-based sterilizing agent transferred from the first piping (22) into the inside of the ballast water piping, the second piping (32) being connected to the injection part(7), and the chlorine-based sterilizing agent that has remained in the sterilizing agent supply device (20) being injected into the inside of the ballast water piping (3) together with the reduction agent from an opening part (7a) that is provided for the injection part (7).
