Ship ballast water treatment system

Abstract

A ship ballast water treatment system is disclosed. The ship ballast water treatment system according to the present invention comprises: an ozone bubble unit provided inside a conduit through which ballast water flows, for turning supplied ozone into bubbles; a flow channel for sea water supply, which is a separate line not diverging from the conduit, and a side part of which is connected to the ozone bubble unit so as to supply sea water to the ozone bubble unit; and a sea water pumping unit provided in the flow channel for sea water supply, for pumping sea water into the ozone bubble unit.

Description

technical field [0001] The present invention relates to a ship's ballast water treatment system, more particularly to a ship's ballast water treatment system, which can sterilize ballast water stored in a plurality of ballast tanks, and these ballast tanks are arranged in Inside the ship, and accept seawater to improve the stability of the ship. Background technique [0002] In general, vessels such as LNG carriers, LPG carriers, container ships, bulk carriers and tankers are designed to transport cargo in marine traffic. Consequently, when cargo is unloaded from the vessel, the center of gravity of the vessel may be shifted upwards, causing the vessel to become unstable. [0003] In other words, as the ship's draft (that is, the depth to which the ship is submerged when carrying a given load) becomes shallow due to unloading cargo from the ship, the hull deflection (refers to the upward bowing of the ship, when the ship's center rise, while loading cargo intensively at th...

Problems solved by technology

These devices must be disassembled prior to cleaning in order to remove sedimented underwater organisms, thus providing complex cleaning procedures and difficulty in removing virulent viruses other than some plankton

[0012] Moreover, in the ballast water treatment plant, sodium hypochlorite is produced by electrolysis of seawater, which is added to ballast water for sterilization of ballast water, and only some microorganisms can be removed by indirect methods, thus providing Low sterilization efficiency and difficult to control sterilization materials

[0013] In addition, the ballast water treatment device uses a filtration device and an electrolysis device respectively to perform sterilization of ballast water in various ways, thus requiring a very complicated operating mechanism and a large space

[0014] Moreover, such devices can destroy some microorganisms through indirect means, thus providing lower sterilization efficiency and difficult to control the sterilization material
