Description

Technical Field [0001] The present invention relates to a ballast water sterilization device,

The present invention relates to a ballast water sterilization apparatus, and more particularly, to a sterilization apparatus having improved cooling efficiency in a sterilization and sludge disposal apparatus using an ultraviolet light emitting diode.

Ballast water refers to seawater filled in the vessel for safe and efficient operation. When a ship is unloaded, it floats on the water as much as the reduced weight, and accordingly, as the center of gravity becomes higher, the rolling motion increases. When operating in this condition, it may lead to rollover accidents. To prevent this, the ship installs a ballast tank inside the hull and holds the ballast water to a certain extent in the water. The lower the center of gravity is, the higher the stability of the ship. In addition, if there is a lot of cargo on one side of the vessel, the opposite ballast tank may be filled with water to balance the balance. Ballast water is an indispensable part of the operation of ships, but the fact that the organisms or pathogens of a specific area are transported to other sea areas by vessels containing equilibrium water, causing the adverse effects of disturbing the environment and ecosystem of the area do.

The treatment techniques that can be used for ballast water treatment can be roughly divided into physical treatment and chemical treatment. Physical treatment techniques include filtration or membrane separation, centrifugation, ultraviolet irradiation, heating, ultrasonic treatment, cavitation, and deoxygenation. Chemical treatments include chlorination and ozone treatment, Hydrogen peroxide, and chlorine dioxide. In addition, processing apparatuses combining physical and chemical processing technologies are being developed.

However, since the manufacture and import / export of mercury-added products are prohibited since 2020, ultraviolet light lamps can not be used. Therefore, a method using ultraviolet light emitting diodes has been proposed. The ultraviolet light emitting diode method has advantages over ultraviolet lamps in terms of long lifetime, low power consumption, and environmental friendliness.

A structure in which the light source unit is cooled by natural circulation through a flow path formed through the inside of the heat sink and a cooling water outlet tube All.

However, the prior art 2 requires a separate structure for natural circulation of ship equilibrium in that it utilizes the natural circulation of ship equilibrium water due to the pressure difference, and requires a separate structure for the equilibrium water to flow into the heat sink This problem is pointed out in that the light source unit is indirectly cooled by the circulating ballast water.
