Abstract
The ballast water treatment system according to an embodiment of the present invention includes a ballast tank for storing seawater outside the vessel inside the vessel and an electrolytic sterilizing solution using seawater stored in the ballast tank, And a sterilization unit for discharging the electrolytic sterilization liquid into the ballast tank.
Description
The present invention relates to a ballast water treatment system.
In general, the ballast tank of a ship is intended to minimize the variation of the center of gravity of the ship by the loading and unloading of the cargo so as to enable safe navigation. The seawater around the ship enters the ballast tank as ballast water, Ballast water can be discharged from the tank to the outside of the ship.
However, the ballast water used for safe operation of the ship has a problem that it becomes a medium for propagating the organisms or pathogens in a specific sea area to other sea areas.
That is, the ballast water to be filled in the ballast tank may include various marine life and pathogens. Since the inflow and outflow of the ballast water occur in different areas, Leaking organisms or pathogens into other waters will cause side effects that disturb the environment and the ecosystem.
Accordingly, the International Maritime Organization (IMO) requires internationally recognized procedures to treat marine organisms or pathogens contained in ballast water when the ballast water is leaked from ships.
At this time, in order to sterilize the ballast water of a ship, recently, it has been proposed to use a sterilizing material such as hypochlorous acid (HClO or ClO-) generated through an electrolysis reaction of salt water, A decomposition type ballast water treatment system has been applied.
Based on the technical background as described above, the present invention provides a ballast water treatment system capable of reducing installation space in a ship.
A ballast water treatment system according to an embodiment of the present invention includes a ballast tank for storing seawater outside the vessel inside the vessel and an electrolytic sterilizing liquid located inside the ballast tank using seawater stored in the ballast tank And discharging the electrolytic sterilizing liquid into the ballast tank.
The sterilizing unit may include a body, a seawater inlet formed on the first side of the body for receiving the seawater stored in the ballast tank, and a second side formed on the body for discharging the electrolytic sterilizing liquid into the ballast tank And a second outlet for delivering the first fluid.
An electrolytic unit for electrolyzing the seawater introduced through the seawater inlet to produce the electrolytic sterilizing liquid may be disposed inside the body.
The body may further include a hydrogen separator for separating hydrogen gas from the electrolytic sterilizing solution produced by the electrolyzer.
And the hydrogen gas may flow out into the ballast tank through the first outlet.
And a second outlet through which the hydrogen gas flows out may be further formed on the third side of the body.
The hydrogen gas flowing out through the second outlet may be discharged to the outside of the ship through a ballast outlet through which seawater flows out of the ballast tank.
A seawater control valve for controlling the inflow amount of the seawater may be disposed at the seawater inlet.
And a ballast pump for introducing the seawater into the ballast tank.
And a filter for filtering the seawater introduced by the ballast pump.
According to the ballast water treatment system as described above, the space occupied by the ballast water treatment system in the ship can be reduced.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, which will be readily apparent to those skilled in the art to which the present invention pertains. The present invention may be embodied in many different forms and is not limited to the embodiments described herein. In order to clearly illustrate the present invention, parts not related to the description are omitted, and the same or similar components are denoted by the same reference numerals throughout the specification.
In addition, since the sizes and thicknesses of the respective components shown in the drawings are arbitrarily shown for convenience of explanation, the present invention is not necessarily limited to those shown in the drawings.
In the drawings, the thickness is enlarged to clearly represent the layers and regions. In the drawings, for the convenience of explanation, the thicknesses of some layers and regions are exaggerated. Whenever a portion such as a layer, film, region, plate, or the like is referred to as being "on" or "on" another portion, it includes not only the case where it is "directly on" another portion but also the case where there is another portion in between.
Also, throughout the specification, when an element is referred to as "including" an element, it is understood that the element may include other elements as well, without departing from the other elements unless specifically stated otherwise. Also, throughout the specification, the term "on " means to be located above or below a target portion, and does not necessarily mean that the target portion is located on the image side with respect to the gravitational direction.
Also, in the entire specification, when it is referred to as "planar ", it means that the object portion is viewed from above, and when it is called" sectional image, " this means that the object portion is viewed from the side.
