Abstract

<P>PROBLEM TO BE SOLVED: To provide a device for efficiently extinguishing, at a low cost, marine organism in a ballast water used for the safe operation of a vessel. <P>SOLUTION: An OHR mixer is fitted directly to the delivery pipe or to the bypass pipe of the delivery pipe of a ballast pump generally used in the ship, and the marine organism flowing through the fed ballast water by the shearing force and impact force of a vortex flow caused in the OHR mixer. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

発明の詳細な説明Detailed Description of the Invention

本発明はＯＨＲミキサーを船舶のバラストポンプの吐出菅に取り付け、海洋生物を死滅させることにより、地球の自然環境の破壊に繋がる海洋生物の遠隔地移動を防止する装置である。
一般的にバラスト水の中にいる海洋生物死滅の手段としてＵＶ照射、流れの中に設置したスリットで発生するキャビテーションの使用、オゾンの添加などが考えられているが、効率の悪さや装置の海水通過部の目詰まりの防止等が必要で、その構造は複雑かつ高価な物となっている。
本発明は高能率のラインミキサーとして知られるＯＨＲミキサーを船舶のバラストポンプの吐出管側に取り付けて、船外からのバラスト水取り入れ時又は、船外への排出時にＯＨＲミキサー内部で発生する渦流の激しいせん断力、衝撃力によってバラスト水と共に流れる海洋生物を効率良く死滅させる装置である。
この海洋生物死滅のためにバラストポンプを動かすことは船舶にバラスト水の張り込みや排出時だけでなく、航海中にバラストタンク内のバラスト水を、ＯＨＲミキサーを吐出管に装備したバラストポンプで吸入し、バラストタンクに返すという使い方でも良い。
また航海中にバラストポンプを使用しバラスト水をＯＨＲミキサー内を通して海洋生物の死滅化を行うためにはバラストポンプ吐出管に直接ＯＨＲミキサーを取り付けるのではなく吐出管のバイパス管として取り付け可能なために、バラストタンクに対するバラスト水の張り込み、排出のためにＯＨＲミキサーの流れ抵抗を考慮する必要が無く、使用するＯＨＲミキサーの容量を小さく出来る。The present invention is an apparatus for preventing remote movement of marine organisms, which leads to destruction of the natural environment of the earth, by attaching an OHR mixer to a discharge rod of a ship's ballast pump and killing marine organisms.
In general, UV irradiation, the use of cavitation generated by slits installed in the flow, and the addition of ozone are considered as a means of killing marine organisms in ballast water. It is necessary to prevent the passage part from being clogged, and the structure is complicated and expensive.
In the present invention, an OHR mixer known as a high-efficiency line mixer is attached to the discharge pipe side of a ship's ballast pump, and the vortex generated inside the OHR mixer when taking ballast water from the outside of the ship or discharging it to the outside of the ship. It is a device that efficiently kills marine life that flows with ballast water by intense shearing force and impact force.
To move the ballast pump to kill the marine life, not only is the ballast water loaded into or discharged from the ship, but the ballast water in the ballast tank is inhaled by the ballast pump equipped with an OHR mixer in the discharge pipe during the voyage. You can use it by returning it to the ballast tank.
In addition, in order to kill marine organisms through the OHR mixer by using a ballast pump during voyage, the ballast pump can be installed as a bypass pipe instead of an OHR mixer directly on the discharge pipe. In addition, it is not necessary to consider the flow resistance of the OHR mixer for filling and discharging the ballast water with respect to the ballast tank, and the capacity of the OHR mixer to be used can be reduced.

ＯＨＲミキサーをバラストポンプ吐出管に装備し、バラスト水をバラストタンクに張り込みながら、またバラスト水排出時にバラスト水に含まれる海洋生物を死滅させるシステム。A system that equips the ballast pump discharge pipe with an OHR mixer and kills marine organisms contained in the ballast water while the ballast water is stuck in the ballast tank and when the ballast water is discharged. ＯＨＲミキサーをバラストポンプ吐出管のバイパス管に取りつけ、バラストタンクに張り込んだバラスト水を航海中にＯＨＲミキサー内を循環させ海洋生物を死滅させるシステム。A system that attaches an OHR mixer to the bypass pipe of the ballast pump discharge pipe and circulates the ballast water in the ballast tank through the OHR mixer during the voyage to kill marine life.
